0001Reference of related application This application is a partial continuation of US Patent Application No. 11 / 045,204 filed on January 28, 2005, the entire disclosure of which is incorporated herein by reference.
0002The present invention relates to the field of cleaning appliances such as handheld dusters and dust mops. More specifically, the present invention relates to a cleaning method utilizing a system having a handle defining a cradle that houses a fluid reservoir attached to a support arm for attaching a cleaning tool. The system as a whole can perform wet, wet or dry cleaning or dust removal.
0003For decades, handheld rags, rags and other cleaning tools remove dust from dressers, coffee tables and other furniture, computers and other appliances, lighting fixtures, interior walls and lintels. Has been used as a cleaning tool for. Therefore, it is generally known to remove dust and dirt from floors, furniture, and other surfaces in the home by rubbing the surface with a rag, cloth, or other cleaning tool to allow dust and dirt to adhere to the cleaning tool. Has been done.
0004In the last half century, new cleaning tools have been developed to assist individuals in performing dust removal and similar cleaning tasks. Although handheld dusters and other cleaning tools are generally known in the art, current commercial designs have a number of drawbacks. For example, US Patent Application Publication Nos. US2004 / 034956Al, US Pat. No. 6,813,801, US Pat. No. 5,953,784 and US Pat. No. 6,550,092 (incorporated herein by reference) are disposable cleaning. Various handheld cleaning devices incorporating pads are disclosed. While some of these devices are suitable for the desired application, they have obvious limitations. For example, none of the above references provide a convenient containment configuration. Conversely, the handle must be physically removed from the cleaning pad support member to store most prior art handheld cleaning tools. Further, the mounting portion of these known devices often includes a press-fitted member, which becomes fragile over time, causing the support member to come off the handle during cleaning.
0005Also, holding means for properly holding the cleaning pad on the support member during dust removal or other cleaning have not yet been developed. For example, the handy mop disclosed in US Patent Application Publication No. US2004 / 0034956A1 discloses an arched protrusion along the lateral side of a parallel mounting plate. The distance between the arched surface and these protrusions may not hold the dust pad properly on the plate during cleaning. Pads often slip off the plate during normal dust removal or cleaning operations by the user.
0006In general, most of the improvements to handheld dusters and mops have been related to improvements to the basic mechanical components of cleaning equipment. These improvements relate to the provision of cheap and rigid tools for dry dust removal or cleaning. However, no attempt has been made in the prior art to provide a handheld cleaning tool that allows selective wet, wet or dry dust removal.
<p num="0007"> It is known that the addition of water or other cleaning fluids to most cleaning pads or systems improves the efficiency with which cleaning equipment adsorbs dust and other debris. Although this is known, handhelds currently include a mountable water or cleaning fluid reservoir accessible on a cleaning tool that allows the user to switch between wet, wet or dry dust removal with one hand. There is no cleaning system. With prior art dust removal and cleaning equipment, it was necessary for the user to obtain a separate spray bottle or other liquid application means when attempting to perform wet dust removal or cleaning. In light of the demand for wet or wet dust removal or cleaning systems and methods, there is also a need for improvements in cleaning liquids associated with such systems and methods.</p><p num="0008"> In addition, improvements to the cloth or cloth usage associated with such systems are needed. Many of the known disposable dust removal or cleaning cloths contained fabrics that did not absorb enough water and dust. Improved cleaning fibers and arrangements that maximize wet and dry absorption of dust removal pads while maximizing the liquid benefits of the cleaning system, although improvements to the dust removal cloth have been disclosed in the art. There is a demand for.</p>

0038As shown in FIG. 2, a suitable spray bottle is a substantially cylindrical bottle having an integral bottom 51, a side wall 53, a second section 55 and a third section 59. The spray cap or nozzle 61 is screwed or press-fitted into the top of the spray bottle. The spray cap 61 includes a pair of opposing flat portions 63a, 63b configured to selectively engage the flanges 71a, 71b of the fluid reservoir accommodating cradle 36. Alternatively, a tab and groove system may be used to form a similar locking mechanism. Alternatively, the spray cap 61 may include a flat or tapered button on only one side. The fluid reservoir 30 can take various forms other than the illustrated spray bottle. For example, it can take the form of an aerosol package, deformable handle or reservoir that disposes fluid through a flexible pouch with a squeeze, jet gun or attachable spray nozzle. In the figure, the fluid reservoir 30 fits inside the cradle 36 of the handle 24, but the fluid reservoir forms the handle of a system that has only the top of the cleaning system (ie, rotating and mounting members) to which it is mounted. Is also possible.
0039The opposing flat portions 63a and 63b of the spray cap 61 are tightly fitted in the handle portion 24, and further play a role of appropriately orienting the fluid reservoir 30 in the cleaning system 20. Alternatively, the fluid reservoir 30 may include a uniquely designed contour that allows it to be meshed and snugly fitted within the fluid reservoir containment cradle 36.
0040FIG. 5 illustrates the bottom 31 of the handle 24 defining the fluid reservoir containment cradle 36. Generally, the cradle 36 is defined by a lower support 37, handle side walls 21a, 21b and two U-shaped supports or rails 44, 46 configured to accommodate the fluid reservoir 30 of the preferred embodiment. .. In a preferred embodiment, the lower support portion 37 comprises a plurality of ribs 39 extending from the inside of the rear wall 23 of the handle portion 24. The front end of the rib 39 defines a lower support 37 configured to support the bottom 51 of the fluid reservoir 30. In a preferred embodiment, the rib 39 comprises a central rib 45 having a length substantially equal to the dimension of the bottom of the fluid reservoir 30. The length of the remaining ribs 39 gradually decreases and tapers away from the central ribs 45 to support the rest of the circular bottom of the fluid reservoir 30. As is clearly shown in FIG. 9, a pair of triangular holding tabs 42a and 42b extend from the opposite side of the cradle 36 in the vicinity of the lower support portion 37. The holding tabs 42a and 42b are configured to frictionally engage and hold the lower side wall 53 of the fluid reservoir 30. The side walls 21a, 21b extending forward from the holding tabs 42a, 42b further define the sides of the fluid reservoir accommodating cradle 36 and are spaced apart to fit tightly around the side wall 53 of the fluid reservoir 30.
0041In the preferred embodiment illustrated, the fluid reservoir 30 is press-fitted or rubbed into the cradle 36 of the handle portion 24, but another configuration for holding the fluid reservoir 30 within the handle portion 24 is also available. For example, Velcro® or rubber bands may be included in the segment of the handle 24 to hold the fluid reservoir 30 within the handle 24. Other support structures or holding functions for holding the fluid reservoir within the handle may be attached to the handle by hinges or other methods.
0042A first U-shaped bottleneck accommodating support 44 is provided near the front end of the fluid reservoir accommodating cradle 36. The first bottleneck accommodating support 44 is press-fitted around the fluid reservoir 30 of the preferred embodiment to accommodate and retain the fluid reservoir 30. As shown in FIGS. 6 and 8, the first bottleneck accommodating support 44 should be press-fitted around the fluid reservoir 30 near the junction 59 of the second section 55 and the third 57 sections of the reservoir 30. It is configured.
0043A second U-shaped spray cap accommodating support 46 is provided slightly in front of the first bottleneck accommodating support 44. The spray cap accommodating support 46 is press-fitted around the spray cap 61 of the fluid reservoir 30 and is configured to hold and direct it. As can be clearly seen from FIG. 7, the spray cap accommodating support 46 is defined by a pair of flanges 71a, 71b extending from the inside of the opposing side walls 21a, 21b. The flanges 71a, 71b are configured to be press-fitted around the flat portions 63a, 63b of the fluid reservoir spray cap 61 when the reservoir is placed inside the cradle 36. The tight fit of the flanges 71a, 71b with the flat portions 63a, 63b allows the spray cap 61 to be properly oriented within the fluid reservoir accommodating cradle 36 so that the spray cap 61 faces away from the cradle 36. In front of the opening 32, a plurality of structural support ribs 48 extending forward toward the rotating member accommodating cavity 50 are formed.
0044Here, referring to FIGS. 6 and 11, a rotating member accommodating cavity 50 is formed at the front end 25 of the bottom portion 31 of the handle portion 24. The rotating member accommodating cavity 50 is defined between the opposing integrated ears 49a and 49b, located at the front end 25 of the handle portion 24. The ears 49a, 49b include opposing grooves 52a, 52b configured to slidably engage the shafts 80a, 80b of the circular rotating member 82 on the inner cavity surface during assembly. The widths of the grooves 52a and 52b are equal to or slightly wider than the dimensions of the shafts 80a and 80b of the circular rotating member 82. The grooves 52a, 52b and the rotating member accommodating cavity 50 are configured to accommodate various other cleaning pad support members 26 or other cleaning tools having a rotating member 82 attached to the distal end. ..
0045At the ends of the grooves 52a and 52b, a mortise 54 is provided which accommodates the shafts 80a and 80b of the circular rotating member 82 and enables the rotating operation thereof. A circular rotation holding tab in which a curved slot 83 extends laterally from grooves 52a and 52b and extends from a rotating member 82.<u style="single">95</u>Define a passage that is configured to allow the movement of. A circular rotation holding tab arranged on the rotation member 82 on the opposite side of the front end of the rotation member accommodation cavity 50.<u style="single">95</u>A circular rotation holding tab hole 87 is provided which is configured to engage with and accommodate this.
0046The elastically biased semi-flexible rotary engagement tab 38 extends downward from the top 29 of the handle portion 24 and enters the rotating member accommodating cavity 50. As described in detail below, the engagement tab 38 is configured to engage a first end 39 attached to the handle 24 and notches 102, 104, 106 on the outer surface of the rotating member 82. It is composed of two free ends 91.
0047A cleaning pad support member 26 is mounted in the rotating member accommodating cavity 50 of the handle portion 24. The cleaning pad support member 26 comprises an integrally formed circular rotating member 82, a connecting portion 93, and a support head as a whole indicated by reference numeral 92. The circular rotating member 82 includes integrated shafts 80a and 80b on opposite sides in the lateral direction. As can be clearly seen from FIG. 11, the shafts 80a and 80b are configured to fit in the mortise 54 and rotate rotatably in the hole. The rotating member 82 further includes a circular rotation holding tab 95. The circular retention tab 95 is configured to fit within the retention tab hole 87 and supports the system in a cleaning position. The rotating member 82 defines three notches or recesses 102, 104, 106 corresponding to the selective position of the cleaning pad support member 26. The cleaning position notch 102, the liquid coating notch 104 and the accommodating position notch 106 are defined on the outer surface of the rotating member 82. Generally, a suitable rotating assembly requires about 2-3 lbf of rotational power to rotate.
0048The connecting portion 93 and the support head 92 are integrally formed with the rotating member 82 and extend from the rotating member 82. As is known in the art, in a preferred embodiment, the support head 92 of the cleaning pad support member 26 is a pair of parallel mounts configured to engage the pockets or sleeves 110a, 110b of the cleaning pad 28. Includes members or mounting projections 108a, 108b. The mounting members 108a, 108b may be spaced apart in various configurations, but in a preferred embodiment, the overall width of the mounting members 108a, 108b is about 1.25 inches from the opposing outer edges. It is desirable that the mounting members 108a and 108b have a length of about 6.75 inches, a wall thickness of about 0.75 inches, and a width of about 0.80 inches. The mounting members 108a, 108b define a rounded tip 107 configured to facilitate insertion of the cleaning pad 28 into the sleeves 110a, 110b. Although a pair of mounting members 108a and 108b are shown in a preferred embodiment, many configurations can be used. For example, a single, wide mounting member may be used. Alternatively, three or more mounting members may be used.
0049Mounting members 108a, 108b include a plurality of separated cleaning pad holding tabs, barbs or protrusions 112 projecting from the top surface 105. In the illustrated embodiment, the retaining tab 112 extends substantially vertically from the top surface of the mounting members 108a, 108b to the first wall 114 and distal to the mounting members 108a, 108b from the upper edge of the first wall 114. A triangular tab with a second sloping wall 116 that slopes towards the edge. The tab 112 is preferably located approximately 0.050 inches above mounting members 108a, 108b. The unique triangular construction of the retention tab 112 serves two functions. The sloping wall 116 facilitates the installation of the cleaning pad 28 on the mounting members 108a, 108b during assembly, and the vertical first wall 114 holds the cleaning pad 28 on the mounting members 108a, 108b during the cleaning operation. To do.
0050In addition to the holding tab 112 having a unique configuration, the cleaning pad 28 is held on the mounting members 108a, 108b by arranging the holding tab 112 on the mounting members 108a, 108b. In the illustrated embodiment, the retaining tabs 112 are alternated and include a front end tab 115, three intermediate tabs 117 and a rear end tab 119. In the illustrated embodiment, each mounting member 108a, 108b includes five retaining tabs 112. Studies have shown that when the retention tabs 112 are equidistant from each other, the retention function is reduced compared to when they are arranged in the alternating configuration shown in the preferred embodiment. In a preferred embodiment, the first tab is 1.0 inch, the second tab is 2.0 inches, the third tab is 2.5 inches, the fourth tab is 3.0 inches, the fifth tab is 4.0 inches, each rounded. It is separated from the tip 107.
0051In one embodiment, the mounting members 108a, 108b may be expandable, inflatable, partially inflatable, or may include an inflatable portion. The inflatability allows the cleaning pad 28 to better fit the mounting members 108a, 108b, and the cleaning pad 28 can be easily removed from the mounting members 108a, 108b without the use of hands.
0052The cleaning pad 28 is generally known in the art and is composed of a combination of a fiber defining a cleaning surface 111 and a mounting portion 113. The cleaning pad 28 may include, for example, a plurality of fluffy synthetic resin non-woven fabrics which may be welded to each other. The pad may contain fibers made of PP, PE, PET fibers in various weight ratios. In the illustrated embodiment, the mounting portion 113 defines a mounting member 108a, 108b configured to accommodate a pair of pockets or sleeves 110a, 110b of the cleaning pad support member 26. The cleaning pad 28 is preferably a 20 g / sqm spunlace cloth manufactured by Haso Corporation of Japan and containing 1 to 4% of mineral oil. Such a cleaning pad or dust removal pad is disclosed in PCT / JP2004 / 10507 (the full text of the patent document is incorporated herein by reference).
0053When the cleaning system 20 is used, the sleeve-shaped cleaning pad 28 is attached to the mounting members 108a, 108b so that all holding tabs 112 are located within the sleeves 110a, 110b. Thus, in this configuration, the retention tab 112 is completely enclosed by the cleaning pad 28, avoiding scratches on delicate furniture and other items accessed by mounting members 108a, 108b.
0054The cleaning surface 111 of the cleaning pad 28 may be composed of a polymer that allows the spontaneous transport of aqueous fluids. Such polymers are disclosed, for example, in US Pat. Nos. 5,723,159, 5,972,505, 5,200,248 (see full disclosure of the patent document). Incorporated in the specification of the present application).
0055The polymer fiber of the cleaning pad can be made into various shapes to enhance various performances and characteristics of the cleaning system 20. As is known in the art, standard circular fibers are available. Alternatively, the individual fibers of the cleaning pad may be lobed into loose tau fibers. The unique rupture configuration creates channels within the individual fibers, improving capillary action in the individual fibers, increasing the overall cleaning or dust removal surface area, and improving the overall efficiency of wet and dry dust removal. .. As the surface area increases, the proportion of particles adsorbed on the grooves or channels increases and dust particles are "trapped" in the grooves of the ruptured fiber. Ripped fibers have generally improved dust retention and have more efficient wet wiping and useful life compared to standard circular fibers. Furthermore, the ruptured fiber can be made rigid, and the wiping pressure can be improved even when the access area is small. The ruptured fiber of the present invention can be composed of a large number of polymers, and PP, PE or PET is regarded as the most cost-effective option. Acrylics or biodegradable polymers can also be used.
0056In yet another embodiment, the cleaning pad 28 may include hard or strut fibers that are attached to a large number of tau fibers. In this configuration, the rigid fiber (usually in the range of about 0.3 mm) supports most of the stress on the cleaning pad 28. The tau may be coupled to a stronger fiber by being entangled at the outer end of the fiber. The rigid fiber provides an elastic cleaning pad 28 with a more desirable feel of the force exerted on the user. Hard fibers can also be used to clean areas that are difficult to clean, such as cracks, blinds, and screens. A further advantage of the rigid fiber is that it expands the tau volume and increases the amount of dust that moves to the tau fiber.
0057In yet another embodiment, the cleaning pad 28 may include a particulate absorbent material that is anchored to the remaining fibers of the cleaning pad 28. The absorbent material may take the form of the known superabsorbent polymer SAP. SAP may be, for example, an acrylic polymer that is applied directly to the fiber as a coating or modified to form the fiber. Examples of commercially available SAPs generally include X-chain polyacrylic acid or X-chain starch-acrylic acid graft polymers, carboxyl groups partially neutralized with sodium hydroxide or caustic potash. SAP can be prepared by a solvent or solvent polymerization method, a back suspension, an emulsion polymerization method or the like. The SAP is disclosed, for example, in US Pat. Nos. 6, 124, 391 (the disclosures of such patent documents are incorporated herein by reference).
0058The absorbent material increases the total absorption of the fiber, prevents the fiber from clumping together and increases the friction of the fiber. The "string of pearls" arrangement also allows the high absorption area to be strategically placed on the cleaning pad. For example, if it is desired to impart higher absorbency to the front end of the cleaning pad 28 as compared to the rest of the cleaning pad 28, the proportion of the fine particle absorbing material at the front end may be increased.
0059The cleaning pad 28 may include spirally formed fibers. Such fibers can be made by stretching fiber bundles onto blades or by heating coaxial composite fibers. The resulting helical fiber has a more fluffy feel and is visually appealing, while at the same time increasing volume (despite the small amount of fiber) and increasing dust retention of the duster. The spiral shape of the fiber has the advantage that the coarse fiber has a soft feel due to the spring effect. In addition, the fiber gradually loses its helical nature, which also serves as an indication of the duration of effect of the cleaning pad.
0060The fiber material or configuration is not limited to the above. Cleaning pads can be constructed by strategically combining various fibers with other known fibers. For example, the cleaning pad can consist of 25-100% by weight ruptured fiber.
0061Similarly, although preferred embodiments disclose a single cleaning surface 111, the invention is not limited to such a single cleaning surface. Conversely, many other configurations are included within the scope of the invention. For example, the pads of the present invention may include a number of cleaning surfaces with different or similar fiber configurations to accommodate various cleaning functions. In one embodiment, the cleaning pad 28 may have two sides. One side may be a dust removing cloth, and the other side may be a cleaning pad 28 for cleaning. This configuration can also be obtained by "turning over" the pad to expose a new cleaning surface. Alternatively, a cleaning pad 28 with a triangular shape or many other faces is also available. Circular cleaning pads are also included in the scope of the present invention. Generally, the various shapes or configurations of the cleaning pad 28 are utilized to maximize the various properties of the cleaning pad 28 and the selected fiber.
0062As mentioned above, there are various options for the arrangement and type of fiber used in the cleaning pad 28. For example, the cleaning pad 28 may include, but is not limited to, a generally fluffy pad that includes a flat central strip around a pocket or area defined by sleeves 110a, 110b. Such an arrangement increases the surface area and enhances the effect. In addition, the central strip may include an absorbent pillow or tube extending downward from the center of the cleaning pad 28. By providing an absorption pillow, an area with a large amount of absorption is provided on the cleaning pad 28. In addition to this, for example, various combinations including a cleaning pad in which sections of sponge, pinnate structure, microfiber or cell roll foam are alternately provided can be considered. Wood pulp is preferred.
0063The cleaning pad 28 may include a fluffy cloth containing a hydrophilic additive to enhance water absorption. Hydrophilic additives include, but are not limited to, glycerin and glycols. The cleaning pad 28 may be composed only of an absorbent material such as rayon.
0064Further, the cleaning pad 28 or the cleaning pad support member 26 may contain a piezoelectric crystal that imparts an electrostatic charge to the cleaning pad during use in order to enhance the dust holding force. Such crystals are generally known and usually generate an electric charge when mechanically stressed. Berlin stone (AlPO) as an example of available materials<sub>4</sub>) And gallium orthophosphate (GaPO)<sub>4</sub>) And other quartz-like crystals, perovskite or tungsten-bronze-containing ceramics (BaTiO)<sub>3</sub>, KNbO<sub>3</sub>, LiNbO<sub>3</sub>, LiTaO<sub>3</sub>, BiFeO<sub>3</sub>, Na<sub>x</sub>WO<sub>3</sub>, Ba<sub>2</sub>NaNb<sub>5</sub>O<sub>5</sub>, Pb<sub>2</sub>KNb<sub>5</sub>Oi<sub>5</sub>), But is not limited to these.

0066In one embodiment, the cleaning pad 28 may include a spunbond fiber comprising web having a base weight of approximately 68 grams per square meter. The spunbonded fiber may include composite fibers having an adjacent configuration, each component containing about 50% by volume of the fiber. The spunbonded fiber comprises a first and / or second polypropylene component and / or a first component containing polypropylene and a second component containing a propylene-ethylene copolymer. In order to increase the opacity of the fiber, about 1% titanium oxide or titanium dioxide may be added to the fiber. The spunbonded fibrous non-woven web is bonded by heating with a point unbonded pattern. Nonwoven web is a pair of counter-rotating bonding By passing between the nip formed by rolls), they are coupled using both heat and molding pressure. The binding roll includes one flat roll and one engraved roll. The binding area of the non-woven web includes a continuous pattern corresponding to the pattern imparted to the engraved roll. In addition, the binding area is conferred on the web as it passes through the nip. The binding region is formed over a region of about 27% to about 35% of the non-woven web, forming a repeating non-random pattern of circular non-bonding regions. Absorbent or superabsorbent materials, including superabsorbent polymers, powders, fibers, etc., may be combined with the cleaning pad 28.
0067Alternatively, the pad 28 comprises a laminate of an air-laid composite and a spunbonded fiber non-woven web. The non-woven web may contain one component spunbonded fiber of polypropylene with a base weight of approximately 14 grams per square meter. The air laid complex may contain from about 85% to about 90% kraft pulp fulff and from about 10% to about 15% short fibers. The short fibers may have a sheath-core configuration, the core component is made of polyethylene terephthalate and the sheath component is made of polyethylene. The base weight of the airlaid complex is about 200-about 350 grams per square meter and the absorbency is about 8-about 11 grams per gram.
0068The cleaning pad 28 may include a hydrophilic fiber portion or side suitable for polishing and cleaning. Further, nylon fiber may be used in order to increase the friction efficiency when used in a wet manner. A portion of the cleaning pad 28 may consist of microfiber or ultramicrofiber with a denier per-filament (dpf) of about 1.0 or less.
0069As mentioned above, the cleaning pad 28 can be made of any material and known material forming steps. Examples include woven and non-woven materials, polymers, gels, extruded materials, laminates, laminated materials that are integrally bonded to form co-materials, molten materials, extruded materials, air laying, etc. Be done.
0070Alternatively, the cleaning pad 28 can optimize the supply of the cleaning fluid to the surface by using microcapsules, encapsulated fluids, or agents. The reinforced surface of the cleaning pad 28 may have a polished or polished quality. Reinforced surfaces can be formed by mechanical stamping, bonding, pressurization, compression, extrusion, spraying, sputtering, laminating or other surface forming or working steps. The various cleaning liquids described above may be microencapsulated and included in the cleaning pad so that they are selectively released by some additional stimulus. The various cleaning liquids microencapsulated and contained in the cleaning pad can be activated by water in the fluid reservoir, other chemicals, or pressure. The solvent may be dry-penetrated. The chemical solution may be encapsulated in a pad 28 or in a pocket or bubble on the pad 28 or on the cleaning medium support 26. The pocket may be designed to explode under moderate pressure and release the cleaning fluid.
0071The cleaning system 20 may be presented with the parts pre-assembled or unassembled. When assembling or manufacturing the cleaning system 20, the ears 49a and 49b of the handle portion 24 formed in advance as described above are forced when the rotating member 82 is inserted between the ears 49a and 49b in the above-mentioned orientation. May be curved outwards from each other. The shafts 80a, 80b slide along the path defined by the grooves 52a, 52b until they reach the (defined) rotating hole 54 defined at the end. The shafts 80a and 80b fit into the holes 54 to define the rotary coupling. The sleeves 110a, 110b of the cleaning pad 28 are placed on the mounting members 108a, 108b to secure the cleaning pad to the system.
0072The circular rotating member 82 conforms to the rotational movement of the cleaning pad support member 26 with respect to the longitudinal axis of the handle portion 24 by about 55 ° to 65 °. Suitable ranges are ideal for adapting to different fiber lengths and cross shapes in the systems of the invention. In particular, it is desirable that the range is about 61 °. When the cleaning pad support member 26 is fully extended in the cleaning position (FIG. 1), the circular holding tab 95 fits into the holding tab hole 87 and holds the cleaning pad support member 26 in the cleaning position.
00731, FIG. 3, FIG. 4, and FIG. 10 show the cleaning system of the present invention in alternating positions. FIG. 1 shows the cleaning system 20 at the cleaning position. As described above, at the cleaning position, the cleaning pad support member 26 extends forward, the rotation engagement tab 38 engages the cleaning position notch 102 of the rotation member 82, and the holding tab 95 fits into the holding tab hole 87. To fit. These engaging or holding properties generate at least 2.5 lbf of rotational power. The magnitude of this turning power is sufficient to hold the cleaning pad support member 26 in a fully extended cleaning position, regardless of the magnitude of torque experienced during normal dust removal, drying, or cleaning operations. Therefore, in the cleaning position, the user can operate the cleaning system 20 via the handle portion 24. In addition, the user can apply the water or other liquid contained in the fluid reservoir 30 directly to the surface to be cleaned. The user may insert a finger through the opening 32 and push down the spray cap 61 to expel the substance contained in the reservoir 30. Since the cleaning system 20 is located in the cleaning position, for example when the system is oriented horizontally when removing dust on the coffee table, liquids or other substances (foaming substances or foamy substances or other substances) in the area behind the cleaning pad 28. Powder) is applied directly to the surface to be cleaned. Alternatively, the cleaning liquid may be sprayed on the vertical cleaning target surface such as a window frame or a door frame.
00744 and 10 show the cleaning system 20 at the second liquid application position. To move the cleaning pad support member 26 to the liquid application position, the user grasps the handle portion 24 and applies torque to the cleaning pad support member 26 to move the cleaning pad support member 26 from the cleaning position shown in FIG. There is a need to. When a torque larger than the force of the engagement characteristic of the present invention is applied, the circular rotating member 82 rotates downward to reach the liquid coating position. At the liquid coating position, the rotary engagement tab 38 engages with the liquid coating notch 104 of the rotating member 82 to hold the cleaning pad support member 26 in an inclined liquid coated state. In the illustrated embodiment, the angle θ between the cleaning pad support member 26 and the handle portion 24 at the liquid application position may be 45 ° to 68 °. The angle θ between the cleaning pad support member 26 and the handle portion 24 is preferably 55 ° to 68 °, and particularly preferably 63 °. This preferred angle takes into account the spray pattern (dotted line) of the fluid reservoir to apply the liquid to the maximum surface area of the cleaning surface 111 of the cleaning pad 28.
0075During dust removal or cleaning, the user may repeatedly rotate the cleaning pad support member 26 from the cleaning position to the liquid application position, if necessary. Alternatively, as described above, the user may simply apply the liquid directly to the surface to be cleaned while using the cleaning system 20 in the cleaning position.
0076Figure 3 illustrates the containment position of the cleaning system. As shown in FIG. 3, at the accommodation position, the cleaning pad support member 26 is rotated rearward so as to be substantially parallel to the plane defined by the longitudinal axis of the handle portion 24. At the containment position, the engagement tab 38 engages with the containment position notch 106 to hold the cleaning pad support member 26 in the folded position. When in the containment position, the cleaning system 20 can be easily stored in various spaces such as kitchen drawers and cabinets. Alternatively, the system can be hung on the wall using the opening 32 in the handle 24.
0077As can be seen from the above description, the present invention includes a novel method of adjusting the cleaning pad support member 26. First, the cleaning system 20 is prepared. Grasp the handle portion (preferably only the handle portion), press the cleaning pad support member 26 against an object (for example, a wall or floor), and rotate the cleaning support member 26 with respect to the handle portion 24. In another embodiment, the rotating member may include a torsion spring or other urging means for returning the cleaning support member 26 to the cleaning position without bothering the user.
0078FIG. 10 illustrates another embodiment of the cleaning pad 128 of the present invention. The cleaning pad 128 is similar to that described above, but the pad 128 includes a tapered fiber 129 on the cleaning surface 111. As shown in FIG. 10, the fiber 129 is tapered so that the fiber 129 closest to the handle 24 is the shortest. The fiber 129 gradually becomes longer as it moves away from the handle portion 24. By tapering the length of the fiber, the cleaning system 20 is adapted to maximize the cleaning fluid coating surface area of the cleaning surface 111 at the fluid coating position.
007912 and 13 illustrate additional embodiments of the cleaning system. As shown in FIGS. 12 and 13, a flexible pouch 130 is provided in place of the cleaning fluid reservoir 30 of the above embodiment. In another embodiment, as described above, a spray nozzle or cap 134 with an inclined immersion tube 140 may be held by the handle portion 24. The user may drill the seal at a preformed position 138 of the pouch with the pumped immersion tube 140. Alternatively, the user may screw the spray cap 134 into the threaded pouch equipment 151, and the spray cap 134 may be moored directly to the pouch 130 during the refilling operation. As shown in FIGS. 12 and 13, instead of the cradle of the above-described embodiment, a snap-fit cover 142 attached to the handle portion 24 via the living hinge 141 is provided. The cover 142 secures the pouch 130 within the cleaning system 20.
0080b. A preferred embodiment of a cleaning pad used with a cleaning solution. 14 to 24 show preferred embodiments of the cleaning pad 28 that can be used with the cleaning system 22 of the present invention. In the preferred embodiment illustrated, the cleaning pad 28 is generally composed of a cleaning fiber mat 203 laminated on one surface of the base sheet 202. It is desirable that the fiber mat 203 be coupled to the base sheet 202 along a central coupling line 204 that extends continuously along the center of the base sheet 202 in the length direction of the fiber mat 203. In addition, the fiber mat 203 is coupled to the base sheet 202 in a spot coupling region 207 that defines a discontinuous line parallel to the central coupling line 204. As described in detail below, the fiber size defining the fiber mat 203 of the cleaning pad 28 can be varied depending on the application, but the fiber size is preferably 1-18 denier.
0081First, referring to FIGS. 14 to 16, the first preferred embodiment of the cleaning pad 28 of the present invention is shown. The cleaning pad 28 is formed by laminating the fiber mat 203 on one surface of the base sheet 202. The base sheet 202 is preferably composed of a non-woven sheet or other equivalent known in the art. It is desirable that the base sheet 202 and the fiber 203 are coupled to each other along the central bond line 204. In the illustrated embodiment, the central bond line 204 extends from the end 212c of the first base sheet to the opposite end 212d of the second base sheet.
0082As shown in FIG. 15, in addition to the central coupling region 204, the fiber mat 203 and the base sheet 202 are coupled in a plurality of spot coupling regions 207. In general, the spot coupling region 207 defines discontinuous parallel dashed lines 205a, 205b, 206a and 206b. In the illustrated embodiment, the dashed lines 205a, 205b, 206a and 206b are parallel to the central bond line 204.
0083The cross-sectional views shown in FIGS. 16 and 17 more clearly show the coupling region of the fiber mat 203. Generally, the fibers of the fiber mat 203 extend freely between the central bond line 204 and the ends 212a, 212b of the base sheet 202, but part of the fiber mat 203 is part of the spot bond region 207 (FIG. 16). Intermittently attached to the base sheet 202 (see). Alternatively, FIG. 17 shows a portion of the fiber mat 203 that is not coupled in the spot coupling region 207 and extends freely from the central coupling line 204 to the end of the fiber 231a. Regardless of the orientation of the spot coupling region 207, in the illustrated embodiment, the ends 231a and 231b of the fiber mat 203 are not coupled to the base sheet 202 and extend freely. Therefore, the cleaning pad 28 is designed so that the fibers of the fiber mat 203 move freely along the length from the central bond line 204 or the spot bond region 207 to the ends 331a and 331b. The unique binding pattern between the fiber mat 203 and the base sheet 202 (characterized by the discontinuous spot coupling region 207 between the central coupling regions 204) reduces the entanglement of individual fibers and fluffs the fabric as a whole. It has a lot of appearance.
0084As most clearly shown in FIG. 15, the spot binding region 207 roughly defines the lines 205a, 205b, 206a and 206b parallel to the central binding line 204. The individual spot coupling regions 207 are formed intermittently in a discontinuous linear manner. The individual spot coupling regions 207 can be formed in various shapes including circles, ellipses, ellipses, straight lines, and the like. The spot coupling region 207 may be formed so that the shape of the spot coupling region 207 is uniform, or the shape may be formed by various combinations of the above shapes.
0085The width of each spot coupling region 207 (along the length of the fiber) is preferably 0.5-5 mm, and the length (along the length direction of the central coupling region) is preferably 2-15 mm. .. It is desirable that the spot engagement regions 207 are separated by 5 to 50 mm. Of course, the individual spot coupling regions 207 may be evenly spaced over the entire spot coupling region 207, or may be spaced in various patterns.
0086In addition to the above orientation of the spot coupling region 207, the spot coupling region 207 is arranged slightly left and right along the width direction (fiber length direction) of the base sheet 202 with each spot centered on a parallel line. It may be located as such. As a result, parallel lines define the center line, and the spot coupling region 207 is arranged in a zigzag pattern on the left and right. Therefore, the spot coupling region 7 does not need to be linearly arranged on parallel lines 205a, 205b, 206a, 206b.
0087As a matter of course, the spot coupling region 207 may be produced with other configurations, and is not limited to the above configuration. For example, the spot coupling region 207 defines one parallel line between the central coupling line 204 and the end 212a and one parallel line between the central coupling line 204 and the opposite end 212b. However, these lines may define only two parallel lines (eg 205a and 205b).
0088Alternatively, the spot coupling region 207 may define three parallel lines between the central coupling line 204, the ends 212a and 212b so that a total of six parallel lines are formed across the cleaning pad 28. Good. Any number of lines can be formed depending on the application.
0089The various spot coupling regions 207 do not overlap in the fiber length direction of the fiber mat 203, thus no coupling occurs at multiple sites along the length of one fiber. As a result, most of the fiber length of the fiber mat 203 is free. Since the fiber mat 203 is not strategically disturbed, the fiber entanglement of the fiber mat 203 is effectively prevented, while the improved foreign body trapping performance and retention performance last for a longer period of time.
0090The fiber length of the fiber mat 203 can be set variously, but in a preferred embodiment, the fiber length in the fiber length direction from the central coupling region 204 to the fiber end is determined from the central coupling region 204 to the base sheet. It should be 50-100% of the length leading to the end of 202 (212a or 212b). In one preferred embodiment, the cleaning pad comprises a base sheet 202 having a width of 300 mm and a length of 200 mm. The length from the central coupling region 204 to the end of the basesheet 202 is preferably 100 mm, and the fiber length of the fiber mat 203 is preferably 50-100 mm.
0091As shown in FIGS. 16 and 17, the fiber end portions 231a and 231b of the fiber mat 203 in the fiber length direction are not bonded to the base sheet 202, and the coupling region from the fiber end portion 231a or 231b of the fiber mat 203. The length of the freely movable fiber varies from about 10-40 mm in the spot coupling region to about 50-100 mm of the fiber coupled only along the central coupling line. The line defined by the spot coupling region 207 is preferably in the range of 10-40 mm from the edge (202a or 202b) of the base sheet 202.
0092As mentioned above, the material of the base sheet 202 can be a non-woven sheet, paper, synthetic resin sheet, or other known material. In the illustrated embodiment, it is desirable that the base sheet 202 is a non-woven fabric sheet capable of trapping various types of foreign substances. The weight of the non-woven fabric used for the base sheet 202 is 10 to 200 g / m.<sup>2</sup>The thickness is preferably 0.01 to 0.1 mm.
0093In a preferred embodiment, when heat-welded fibers are used in the fiber mat 203, it is desirable that the base sheet 202 has a heat-welding capability that is heat-conducting to the bond with the fiber mat 203. Similarly, when a non-woven fabric sheet is used, it is desirable that the non-woven fabric sheet be heat weldable to the fiber mat 203. As described above, examples of such heat-weldable short fibers include polypropylene, polyethylene, polyethylene terephthalate and other fibers, or materials in which the fibers exist in a core-sheath structure or a parallel structure to form a composite fiber. Be done.
0094The non-woven fabric sheet used as the base sheet 202 can be a spunless non-woven fabric, a spunbonded non-woven fabric, a heat-bonded non-woven fabric, an air-through-bonded non-woven fabric, a spot-engaged non-woven fabric, and the like. In a preferred embodiment, a spunless non-woven fabric or a heat-bonded non-woven fabric is used. The non-woven fabric sheet can be formed from a single sheet, or can be formed by laminating a large number of sheets of the same or different types.
0095The fiber mat 203 used for the cleaning pad 28 can be made by stacking a large number of fibers so that the large number of fibers are in the same direction, or can be formed from a fiber aggregate. It is desirable that the fiber mat 203 has a sheet shape. Further, the fiber mat 203 may be partially coupled between various fibers by means such as welding. The fiber mat 203 may include all uniform fibers or may consist of many types of fibers.
0096The fiber mat 203 can be manufactured from fibers having the same thickness or various thicknesses. Similarly, the fiber mat 203 may be formed from an aggregate in which fibers of different colors are used regardless of whether the thickness and type of the constituent fibers are the same or different.
0097As mentioned above, a wide variety of fibers are available for fiber mat 203, such as cotton, wool and other natural fibers, polyethylene, polypropylene, polyethylene terephthalate, nylon, polyacrylic acid and other synthetic fibers, core sheath type. Examples include fiber, sea-island type fiber, parallel fiber and other composite fibers. Synthetic fibers and composite fibers are suitable because they have thermal welding properties. In one preferred embodiment, the tow is a two-component fiber consisting of a polypropylene core and a polyethylene outer surface or sheath. For example, in one embodiment the tau is a two-component fiber consisting of a polypropylene core and an outer surface or sheath of polyethylene. This is particularly desirable because both materials have excellent thermal welding properties. Further, the fibers used in the fiber mat 203 may be formed of a crimped material made by mechanically shrinking or heat shrinking.
0098In one preferred embodiment, the fiber mat 203 may be a long fiber mat, commonly referred to as "tau", made from polyethylene, polypropylene, nylon, polyester, rayon or similar materials. The thickness of the fibers constituting the fiber mat 203 is preferably 1 to 18 denier. In addition, the weight of the fiber mat 203 is 5-30 g / m when the fiber thickness is about 2 denier.<sup>2</sup>Is desirable.
0099The cleaning pad 28 of the present invention is obtained by laminating a fiber mat 203 on the surface of the base sheet 202 and bonding the two along the central bond line 204 and the spot bond region 207 as described above. Bonding can be done by thermal welding, ultrasonic welding, joining, contacting, or other known methods.
0100In a preferred embodiment, the base sheet 202 and the fiber mat 203 are formed of a heat-weldable material, and the laminate of the base sheet 202 and the fiber mat 203 is heated and pressurized by a hot roll to bond both surfaces. .. Alternatively, if the base sheet 202 or fiber mat 203 is not weldable, a heat-bondable material, such as a hot melt adhesive, may be laminated between the two, or the adhesive may be applied directly between the two layers. You may combine by doing.
0101As mentioned above, the fiber mat 203 or basesheet 202 may be coated with a chemical to improve foreign matter trapping performance. Examples of such chemicals include liquid paraffin and other mineral oils, silicone oils and nonionic surfactants.
0102When a suitable cleaning pad is incorporated into a suitable cleaning system 22, the fiber mat 203 is laminated on one side of the base sheet 202 and coupled in the central coupling region 204. Further, the coupling is carried out in the spot coupling region 207, which is formed discontinuously along the parallel line between the two ends 212a, 212b, parallel to the central coupling region 4. Therefore, a cleaning pad 28 is formed in which the two longitudinal ends of the fiber mat 203 are not coupled to the base sheet 202.
0103As shown in FIGS. 18, 19 and 21, the pocket or sleeve 110 of the cleaning pad 28 is formed by laminating and joining the holding sheet 221 on the back surface of the base sheet 202 (the surface opposite to the fiber mat 203). As a result, the holding opening 222 forming a space in which the arms of the mounting members 108a and 108b of the cleaning tool 22 can be inserted and held is formed. In one embodiment, the retaining sheet 221 is bonded to the base sheet along a central bond line 204 and a spot bond region 207 used to bond the fiber mat 203 to the base sheet 202, defining the two sleeves 110a, 110b. To do. The holding sheet 221 does not need to be connected along the same line as the fiber mat, and may have various configurations as long as it defines the holding opening 222.
0104As most clearly shown in FIG. 18, the base sheet 202 of the cleaning pad 28 has a large number of cuts or fringes 225 cut in the same direction as the fiber length of the fiber mat 203. May be good. The fringe 225 increases the surface area of the cleaning pad 28 and improves the dust adsorption property.
010519 to 21 show a cleaning pad 28 in which the fiber mat 203 is formed by superimposing two or more fiber mats 203a, 203b composed of different types of constituent fibers, different fiber sizes or different colors. Another preferred embodiment is illustrated. By stacking various fiber mats, a cleaning pad 28 having different characteristics can be obtained. In one preferred embodiment, thick fiber fiber mats 203a and thin fiber fiber mats 203b are provided alternately. For example, a fiber mat with a size of 0.01 to 0.05 mm is suitable for a thin mat 203a, and a fiber mat with a size of 0.06 mm to 0.3 mm is suitable for a thick mat 203b. Further, it is desirable to use a fiber having a high stem strength such as polypropylene or nylon for the thick fiber mat 203b. The thick fiber mat 203b is preferably composed of a bundling fiber formed by splitting the drawn polypropylene tape in the drawing direction. It is desirable that the thick polypropylene fiber mat 203b be bonded only at the central bond line 204 to a suitable thin mat 203b formed of a two-component tau fiber consisting of a polypropylene core and an outer surface of polyethylene. Therefore, as shown in FIG. 21, the thick fiber mat 203b hangs freely from the cleaning pad 28. As a result, the fiber pad has a bulky and fluffy appearance.
0106As described with reference to FIGS. 14-17, the dual fiber mat 203 may be made by laminating a thin sheet 203a on a base sheet 202. The thick fiber mat 203b is then laminated on the thin fiber mat 203 and both are coupled along the central bond line 204.
0107The stacking of alternative fibers in the fiber mat can be done in various ways, but in the illustrated embodiment the thick fiber 203b is on the outside (the surface to be cleaned). Such an arrangement is particularly suitable for cleaning surfaces and appliances that include small gaps, such as computer keyboards. The thin fiber 203a does not have a main body and does not easily enter the gap. However, in contrast, the thick fiber 203b has a high stem strength that allows it to easily enter the gap and lift dust, dirt and other debris from the surface to be cleaned. In addition, the thick fiber 203b prevents entanglement of the thin fiber and provides a rough surface for removing debris stuck to the surface.
0108In the illustrated embodiment, the length of the thick fiber mat 203b in the fiber length direction is preferably somewhat shorter than the length of the thin fiber mat 203a, but the length can be varied depending on the application.
010922 to 24 illustrate another preferred embodiment of the cleaning pad 28, specifically a holding sheet. The holding sheet 221 of the cleaning pad 28 is made by laminating two sheets of non-woven fabric 221a and 221b, heat sealing, and joining the center and the three sides to define the insertion opening 223. The sack-shaped holding portion 222 including a space for inserting and holding the mounting members 108a and 108b is formed between the two non-woven fabrics 221a and 221b.
0110As shown in FIG. 23, the insertion opening 223 of the holding sheet 221 is formed. The holding sheet 221 shown in FIG. 25 may be made by folding one non-woven fabric in two, sealing a specified portion, and forming an insertion opening 223. The upper non-woven fabric 221a is formed to function as a boundary 229 that is freely curable upward at the end of the sealing region 228 and is therefore not bound to the lower non-woven fabric 221b.
0111In one preferred embodiment, a colored region or other marking 224 indicating the orientation of the insertion region 223 may be provided at the end of the boundary 229. As a result, when the upper non-woven fabric 221a is formed longer than the lower non-woven fabric 221b and the boundary 29 is provided, the mounting members 108a and 108b can be easily and smoothly inserted.
0112Instead of providing a colored portion as a mark 244 at the boundary 229 of the holding sheet 221, an embossing process may be performed to provide a raised pattern at the same position. By providing a mark on the insertion opening side 223 of the holding sheet 221, the area where the mounting member 108 is inserted can be easily identified.
0113As shown in FIG. 24, the holding sheet 221 is formed by applying a hot melt adhesive 227 to the center of the base sheet and laminating and heating the holding sheet 221 and the base sheet by means such as heating or pressure welding. Attached to 202. The holding sheet 221 can be attached to the cleaning pad 28 using an adhesive or pressure sensitive adhesive, and a hot melt adhesive.
0114The cleaning pad is attached to the attachment member 110 by inserting the attachment members 110a and 110b into the insertion opening 223 of the holding sheet 221 so that the attachment member 110 is held by the holding portion 222. When the cleaning pad 28 becomes dirty, the arm mounting member 110 is pulled out from the insertion opening 223, and an unused cleaning pad 28 is attached.
0115The fibers disclosed by combining the coupling of the fiber mat 203 to the central coupling region 204 with the coupling to the spot coupling region 207 and because the longitudinal end of the fiber of the fiber mat 203 is not coupled to the base sheet 202. The fiber of the mat 203 has more fluff than the conventional cleaning pad, and it is possible to form a bulky region of the fiber. This offers significant advantages over the less bulky fabrics of the prior art. Both ends of the fiber mat 203 in the length direction of the sheet hang downward, and the fiber tips at both ends of the fiber are released from the base sheet and are movable. For this reason, the disclosed fiber mat 203 has dust, dirt and dust and dirt as compared to conventional sheets for cleaning tools in which long fiber filaments are cut to fluff the surface or sandwiched between two carrier sheets. Has excellent trapping performance and holding ability against various types of foreign matter.
0116The preferred embodiment of the cleaning pad 28 is particularly suitable for the system 20 of the present invention capable of performing wet, wet or dry cleaning or dust removal. Known prior art cleaning pads, more specifically dust removal pads, were hydrophobic. As a result, prior art cleaning pads cannot take advantage of the present invention when utilizing low level liquid products.
0117The cleaning pad of the present invention enables the wet, wet or dry dust removal method of the present invention. In particular, the system 20 of the present invention utilizes low level liquid products in combination with dry dust removal or cleaning pads 28 to improve dust removal performance. In a preferred embodiment, the liquid level used is 0.01-0.3 g / sq ft. Alternatively, a suitable liquid level applied to the cleaning pad is 80-500 microliters. The range of 120 to 130 microliters is particularly suitable. Water, solvents or emulsification-based intermediates can be used as liquids as described throughout the specification.
0118c. How to use and clean As can be seen from the above disclosure, the suitable cleaning tool 22 can be used for cleaning various surfaces and removing dust. Due to the unique configuration of the cleaning tool 22, the user can switch between wet, wet or dry cleaning or dust removal as appropriate. The components of the present invention can be appropriately replaced at hand according to a specific cleaning task. For example, some of the disclosed cleaning pads 28 are suitable for use with the disclosed cleaning liquids or for dry dust removal. Similarly, some cleaning pads 28 include another surface configured for another cleaning task. Similarly, the cleaning solution used can be varied according to the desired application.
0119The user may obtain the cleaning system 20 including a suitable cleaning tool 22 for dry dust removal. The user grips the cleaning tool 22 so as to surround the handle portion 24 with the palm of his hand. In a preferred embodiment, the palm of the user extends beyond the end of the top 29 of the handle 24, and the fingers of the user extend at least partially around the fluid reservoir 30. The fluid reservoir 30 may not be present when performing the dry dust removal task. In the illustrated embodiment, the user's hand is typically oriented so that the index finger can be inserted into the hole 32 extending into the handle portion 24.
0120When the user obtains the cleaning tool 22, the cleaning pad 28 is installed on the cleaning pad support member 26. As described above, the cleaning tool may be used together with various cleaning pads 28. In a preferred embodiment, the sleeve-shaped cleaning pad 28 is mounted on mounting members 108a, 108b such that all retaining tabs 112 are within sleeves 110a, 110b. When the cleaning pad 28 is fixed, the user places the cleaning pad 28 on the surface to be cleaned and moves the cleaning pad 28 on the surface to be cleaned. By moving the cleaning pad 28 on the surface to be cleaned, dust or other debris is collected by the cleaning pad 28. In the illustrated embodiment, dust or other debris is collected by the cleaning surface 111 of the cleaning pad 28. The user may rotate the cleaning pad support member 28 according to the surface to be cleaned to handle a place that is difficult to reach. For example, when the user wants to remove dust from the overhead forage, the cleaning pad support member 26 can be rotated by about 90 ° with respect to the handle portion 24.
0121A suitable dust removal or cleaning pattern consists of overlapping left and right movements, starting from the upper left (or upper right) of the section to be cleaned and advancing the wiping pattern over the entire surface to be cleaned while continuing the wiping operation to the left and right. Another suitable wiping pattern consists of a vertical wiping operation. By using a suitable wiping pattern, the cleaning pad 28 loosens dirt and dust, and a better finish can be obtained. Another advantage of the wiping pattern is that it minimizes the formation of streaks as a result of improved application of the liquid (in wet dust removal).
0122Wet dust removal or cleaning can be performed separately, in combination with, or in addition to dry dust removal. For example, the user may first perform dry dust removal and then wet dust removal or cleaning. In the case of wet cleaning or dust removal, the same step is performed in the case of the dry dust removal described above. However, the cleaning fluid reservoir 30 is first inserted into the fluid reservoir accommodating cradle 36 as needed. The fluid reservoir 30 is inserted between the handle side walls 21a and 21b into two U-shaped supports or rails 44 and 46. The fluid reservoir 30 is press-fitted into the cradle so that the triangular holding tabs 42a, 42b are frictionally engaged and hold the lower side wall 53 of the fluid reservoir 30. The reservoir needs to be press-fitted so that the first bottleneck accommodating support 44 fits around the fluid reservoir 30 near the junction 59 between the second section 55 and the third section 57 of the reservoir 30. The second U-shaped spray cap receiving support 46 fits around the spray cap 61 of the fluid reservoir 30 to hold and orient the spray cap 61. The spray cap receiving support flanges 71a, 71b are press-fitted around the flat portions 63a, 63b of the fluid reservoir spray cap 61 when the reservoir is placed in the cradle 36. The tight fit defined by the flanges 71a, 71b and the flats 63a, 63b serves to orient the spray cap 61 into the fluid reservoir containment cradle 36 appropriately so that the spray cap 61 is oriented away from the cradle 36. ..
0123When removing or cleaning wet dust, moisten the surface to move the cleaning pad 28 on the surface to be cleaned, moisten the cleaning pad 28 to move the cleaning pad 28 on the surface to be cleaned, or a combination of the two. Various technologies that combine the above can be used.
0124FIG. 1 shows a cleaning system 20 in a cleaning position configured for wet cleaning, where the cleaning liquid is applied directly to the surface. As described above, at the cleaning position, the cleaning pad support member 26 extends forward, the rotary engagement tab 38 engages with the cleaning position notch 102 of the rotary member 82, and the holding tab 95 is inside the holding tab hole 87. Fits to. At this position, the user may apply water or other liquid contained in the fluid reservoir 30 directly to the surface to be cleaned. The user may insert a finger through the opening 32 and push down on the spray cap 61 to release the liquid contained in the reservoir 30.
0125FIG. 4 shows the cleaning system 20 at the second liquid application position. In order to move the cleaning pad support member 26 to the second liquid application position, the user grasps the handle portion 24 and applies torque to the cleaning pad support member 26 to clean the cleaning pad support member 26 as shown in FIG. Move from position. When a torque exceeding the force of the engagement characteristic of the present invention is applied, the circular rotating member 82 rotates downward to the liquid coating position. At the second liquid coating position, the rotary engagement tab 38 engages with the liquid coating notch 104 of the rotating member 82 to hold the cleaning pad support member 26 in an angled liquid coating state. At this position, the user may apply water or other liquid contained in the fluid reservoir 30 directly to the cleaning surface 111 of the cleaning pad 28. As mentioned above, the various cleaning positions can be used interchangeably. At the time of dust removal or cleaning, the user can repeatedly rotate the cleaning pad support member 26 from the cleaning position to the liquid application position as needed. When removing or cleaning wet dust, the user can utilize the cleaning pattern described above.
0126Upon completion of cleaning or dust removal, the user may remove and dispose of the cleaning pad 28 and place the cleaning system 22 in the containment position (see FIG. 3). In order to place the cleaning system 22 in the accommodation position, the cleaning pad support member 26 is rotated in the opposite direction so as to be substantially parallel to the plane defined by the longitudinal axis of the handle portion 24.
0127As described above, various cleaning liquids can be used with the cleaning system of the present invention. In one preferred method of light cleaning or dust removal, the cleaning solution is approximately 96.30% by weight of tap water, 1% of isoparaffin hydrocarbon solution such as Exxon Mobil's Isopar E, and Dow. 1% silicone solution, 0.5% monolaurate sorbitan, preferably 1000estks polydimethylsiloxane silicone oil from Dow Corning, General Electric Silicones, or Rodia Chemical , Polyoxyethylene (20) sorbitan monolaurate or other emulsifier 0.5%, and Stephen Chemical (Stepen) It is a mixed liquid containing 0.15% of a quaternary substance (Chemical) such as BTC2125M. Ideally, this composition is applied to dust removal jobs. By using a suitable liquid agent together with the cleaning liquid agent of the present invention, the dust and allergen retention capacity can be enhanced, and an improved gloss can be given to the surface to be cleaned. Fingerprints, stains and other stains are easily removed.
0128In another preferred embodiment, the cleaning solution is 96.5125% by weight of deionized water, 1.75% anhydrous propane-2-ol, 0.40% ethylene glycol monobutyl ether, 0.40% ethylene glycol n-hexyl ether, propylene glycol. Contains 0.125%, monoethanolamine 0.10%, vinegar (white, 300 grains distilled) 0.30%, a small amount of surfactant, and other ingredients.
0129In another preferred embodiment, the cleaning solution is 97% deionized water, 1.50% anhydrous propane-2-ol, 0.30% ethylene glycol N-hexyl ether, 0.13% industrial grade propylene glycol, and surfactant. Contains 0.08% agent, 0.30% Mackam, 0.10% monoethanolamine, a small amount of surfactant, and other ingredients.
0130In yet another preferred embodiment, the cleaning solution is 91.8% deionized water, 5.0% isoparaffin hydrocarbon, 0.25% ELFUGIN AKT, 0.15% sodium n-cocoy lsarcosinate, 2.0% silicone solution, 0.15% sorbitan mono oleate, 0.15% polyoxyethylene sorbatane monolaurate, 0.15% low freeze grade triethanolamine, 0.15% formaldehyde, and Contains a small amount of other ingredients.
0131In another embodiment, the cleaning solution is 92.32% deionized water, 5% isoparaffin hydrocarbon, 2% silicone solution, 0.15% sorbitan monooleate, 0.15% monolaurate polyoxyethylene sorbatane, tri. Contains 0.03% ethanolamine, 0.15% formaldehyde and a small amount of other ingredients.
0132It is important to control the dose and range of cleaning fluids. In one preferred embodiment, the liquid level to be used with a suitable cleaning pad by application to the cleaning surface is 0.01-0.3 g / sq ft. Alternatively, a suitable liquid level applied directly to the cleaning pad is 80-500 microliters. Especially desirable is in the range of 120-130 microliters. For best results, the product is applied to the treated surface or cleaning pad 28 at the recommended dose above, then the cleaning pad 28 moves over the surface to collect dust and is applied directly to the cleaning surface. Absorbs the cleaning liquid. Instructions for use of the cleaning system may include drawings and / or descriptions detailing suitable application patterns and doses. As mentioned above, suitable compositions of the present invention are mild and minimize damage to most surfaces.
0133As described above, in the case of wet dust removal, the cleaning liquid can be sprayed using the fluid reservoir 30. If desired, additional compositions may be transported in the form of pre-moistened cleaning pads 28 for further convenience.
0134If necessary, most preferably, convenience and performance can be maximized by utilizing the system consisting of the disposable cleaning pads 28 described above. The pad can be configured with any of the cleaning pads 28 described above.
0135This cleaning system 22 and usage offers a number of advantages over traditional cleaning modes. The cleaning pad retains a larger amount of dust and a suitable cleaning solution removes fingerprints, stains, and other marks formed on the surface, thus reducing the time required for cleaning or dust removal. There is no need to carry a separate dust removal liquid or cleaning liquid. Due to the high absorbency of the pad, the pad absorbs and adheres dirt and dust when used in combination with a particularly suitable cleaning solution, and a single pad 28 can clean a large surface area.
0136Furthermore, since the unused pad 28 can be used every time, bacteria and dirt are trapped, removed and dumped, which is excellent in hygiene. Traditional reusable dust removers have the potential to accumulate dirt and bacteria and spread them throughout the home. By controlling the dose by the operator, dirt is removed more effectively and the finished result is good.
0137In addition, the cleaning process is at a low level over a significantly shorter period of time compared to conventional cleaning systems (eg, in the present invention a combination of multiple steps of applying a separate cleaning solution and gripping the cleaning tool). The surface safety of the system and method to delicate surfaces is improved because it involves the use of the liquid in contact with the surface to be cleaned.
0138The cleaning pad 28 is versatile because it is used for various cleaning and various surfaces. Each pad is designed to clean at least one average size surface that has accumulated average debris or dust. Pads can be replaced immediately if the surface is wider than average or if it is particularly dirty. To determine if the pad needs to be replaced, look behind the cleaning surface of the cleaning pad to see if the cleaning surface is saturated with dust and / or dirt.
0139In order to maximize the synergistic effect of the various cleaning and dust removal tasks, the methods of the present invention can be carried out using various practices and usage instructions. In one embodiment, a kit with multiple cleaning pads and liquids for different cleaning tasks may be provided. One liquid and cleaning pad may be for surface cleaning and another liquid and pad may be for dust removal. Kits may be sold separately with notices and instructions on each kit used to illustrate the benefits of using different products together.
0140The above-mentioned parts of the system 20 of the present invention may be manufactured and sold separately, or may be comprehensively manufactured and sold in the form of a cleaning system or a kit. The present invention also considers various additional configurations and components that allow the handle portion 24 to be mounted within the rotating member housing cavity 50. Instead of the cleaning pad support member 26, various replaceable cleaning tools may be used. Another cleaning tool preferably includes a modularly designed support member, including a general purpose rotating member or other mounting member described in the preferred embodiment so that it can be used in exchange for a suitable handle portion 24. .. For example, other cleaning tools such as squeegees for cleaning windows, mirror surfaces or other glass structures, soft surface cleaners such as lint rollers, glass cleaners, indexing rolls, bug slaps, dog brushes or other grooming tools, etc. Examples include, but are not limited to, washing brushes or other cleaning tools. Numerous other rotatably or movably mounted cleaning tools are also included within the scope of the invention.
0141Further, in a preferred embodiment, the handle portion 24 rotatably attached to the cleaning pad support portion 26 has been illustrated, but the present invention is not limited to such a configuration. For example, the cleaning system 20 of the present invention may be configured as a single non-moving component that allows only spraying of the cleaning fluid onto the surface. Similarly, the cleaning pad support may not be rotatably attached to the handle as described in a preferred embodiment. Many other embodiments that allow the cleaning pad support 26 to be moved relative to the handle are within the scope of the invention. Alternatively, the cleaning pad support member 26 and the handle portion 24 are slidably connected, connected by a hinge, and movably connected to various desired arrangements by bending or other means. A lock switch with a spring may be used to allow 180 ° rotation of the cleaning pad support member 26. The cleaning pad support member 26 may include a centrally located rotating member that allows 360 ° rotation. Alternatively, the handle may be rotatable 360 ° with respect to the cleaning pad support member 26. In addition, the handle 24 may include an integral or attachable nested extension that allows dust removal or cleaning of areas outside the reach of the normal user.
0142Further, the handle portion described above may not be installed and the fluid reservoir may be configured to form the handle of the cleaning system. The rotatable mounting member is mounted at the top of the fluid reservoir. Further, although the spray bottle described above is a physically separate module, it is clear that the spray bottle may be incorporated directly into the associated handle or form a handle. The reservoir may have a plug that can be removed when the fluid is filled.
0143Alternatively, the cleaning pad support portion may be connected to the handle portion by a screw connection. Such an arrangement facilitates the attachment and detachment of many other cleaning tools within the scope of the present invention. Alternatively, the cleaning pad support may be configured to rotate vertically or horizontally to suit various cleaning functions. In addition, the cleaning system may include an electric rotary head that is more effective and does not bother the consumer.
0144Although the cleaning fluid transport system has been described by taking a fluid reservoir as an example, other configurations for transporting the cleaning fluid to the surface to be cleaned or the cleaning medium are also included in the scope of the present invention. For example, the fluid reservoir may be configured such that the cleaning fluid can be sprayed or applied to the back of the cleaning pad or cloth and can penetrate and move to the cloth by wicking action. Alternatively, the cleaning system mounting members or teeth 108a, 108b may fluidly communicate with the cleaning fluid reservoir so that the cleaning fluid can be drained onto the cleaning pad 28 through the mounting members 108a, 108b. Such a transport system can transport the cleaning fluid through the tip, bottom, top or side of the mounting member. Alternatively, the liquid transport system may include a flip out nozzle or reservoir configured to spray the cleaning fluid onto the cleaning medium. Such a configuration eliminates the need for a rotation support member.
0145d Manufacturing method A variety of molding and manufacturing techniques can be used to manufacture the cleaning tool 22. In one embodiment, the manufacturing method generally comprises making a handle 24 with a cradle for accommodating the fluid dispenser 30, connecting the cloth support 26 to the handle 24, and tapering the fibers to clean the cloth. 28 includes forming the cross 28 so that the cloth 28 can be secured to the support 26 so that the fiber closest to the handle 24 is shorter than the fiber closest to the free end of the support member.
0146It is desirable that the handle portion 24 is configured such that the rotation point is defined by the rotating member accommodating cavity 50. The rotating member accommodating cavity 50 is configured to be located below the horizontal plane 30 defined by the fluid reservoir, and the rotating member accommodating cavity 50 is configured to include a cantilever rotating engaging tab 38. It is also desirable that the handle be configured to provide an opening 32 to allow the user to access the reservoir storage cradle 36 housed within the handle 24 with one hand. The reservoir containment cradle 36 is formed to define a plurality of grooves 39 configured to engage and secure the spray bottle in the cavity.
0147Two U-shaped supports, or rails 44, 46, are formed within the side wall of the handle, which are molded to accommodate the spray bottle 30. Further, the holding tabs 42a and 42b are frictionally engaged with the lower side wall of the spray bottle 30 and molded in the cradle 36 to hold the lower side wall. When the handle is configured, the handle 24 and a plurality of structural support ribs 39 extending forward from the rotating member accommodating cavity 50 are formed. In addition, a pair of ears 49a and 49b are formed in the handle 24. The ear is formed on the medial cavity surface, including opposing grooves 52a, 52b. It is desirable that the grooves 52a and 52b have dimensions that allow them to slidably engage with the shafts 80a and 80b of the circular rotating member 82. The rotating member 82 is formed including the shafts 80a and 80b. The bottleneck portion of the cradle is formed to define the first bottleneck accommodating portion 44.
0148Various methods can be used, but in one embodiment the cleaning tool 22 is formed using an injection molding process. The method involves injecting plastic into the mold to form the handle 24 of the cleaning tool. The mold is configured to define a handle 24 having an opening for access to the fluid reservoir 30. The second mold is used to form the cleaning pad support 26. The plastic is introduced into the mold to form the cleaning pad support member 26. A blow molding step is then utilized to form the fluid reservoir 30. In the final process, the parts of the cleaning tool 22 are assembled and packaged for distribution.
