DESCRIPTION

Cleaning cloth and cleaning apparatus.

This invention relates to a dry-type bag-shaped cleaning cloth made of a cleaning sheet, and a cleaning apparatus to which the cleaning cloth is attached.

A cleaning apparatus has recently been proposed as a device for cleaning a room, etc. This cleaning device is quieter and more manageable than a vacuum cleaner. This cleaning apparatus is made of a dry type cleaning sheet that does not require water as required in the case of an ordinary floor cloth. Examples of such cleaning apparatus so far proposed include a cleaning apparatus in which a joining plate is mounted to an end portion of its handle and a disposable wiper sheet is attached to the joining plate (see Publication of Japanese Patent 7-8434), and a cleaning apparatus in which a damping material is employed as a cleaning cloth (see Japanese Utility Model Publication 6-34773).

US-A-4,829,622 relates to a cleaning device including a head and a handle. The head includes several blades that are provided with a stitched area. Each sheet has an edge portion, an outer portion, and an inner portion. The handle is inserted into the inner portion defined by the stitched area. The cleaning device works in such a way that the edge portion and the outer portion of the blades perform the cleaning operation, as shown in Fig. 6. In addition, the handle is formed by bending a rod-shaped material, as shown. shown in the figures, and the inner part of the rod-shaped material that is introduced into the inner portion is a space. The dimensions of the outer portion as claimed in the present invention are not disclosed.

FR-A-1,487,987 discloses a cleaning apparatus having a sponge-shaped cleaning element, and not a flat bag cleaning cloth having the shape and dimension claimed in the present invention.

Conventional cleaning devices are suitable for cleaning an area that was open and wide, but are unsuitable for cleaning a confined space such as a space between adjacent keys on a keyboard, a space between adjacent operating keys on various types of devices. OA, and anaologues. Furthermore, conventional cleaning apparatuses have the drawbacks that since the cleaning sheet has to have an overlap width to join the joining plate and the overlap width cannot perform the cleaning function, they are economically inefficient.

Furthermore, conventional cleaning apparatuses have the problems that if a head portion is too soft or flexible, an end of the head portion, which is easily deformed according to the shape of an object to be cleaned, is susceptible to fatigue and therefore, it is difficult to completely remove dirt such as dust, etc., firmly attached to the head portion. In contrast, if the head portion is too hard, the intimate bonding ability of the head portion to the object to be cleaned is degraded. It is difficult for the cleaning apparatus to exhibit its full cleaning effect. Sometimes there is a danger that the hard head portion will damage the object to be cleaned and / or the cleaning cloth will be torn during a cleaning operation.

If it is possible in such conventional cleaning apparatus to prevent a part of the wiping cloth from getting dirty, it is convenient for its user because the user can turn the wiping cloth upside down or remove it, when necessary, from the portion of the cloth. head by grasping the clean part of the cleaning cloth.

Furthermore, in such conventional cleaning apparatus, it would be desirable that the used surface of the cleaning cloth can be easily changed to an unused surface.

As known household cleaners for cleaning dust attached to items such as furniture, electrical appliances, lighting appliances, etc., there are feather dusters having a plurality of wire-like elements arranged at an end portion of the head. These conventional feather dusters have the function of removing and cleaning the dust particles attached to the surface of the object to be cleaned.

Since conventional feather dusters are primarily designed for the use indicated above, it is difficult for them to remove dust adhering to a wide area of the object.

Therefore, a first object of the present invention is to provide a cleaning cloth that can be suitably used to clean even a small space. The second object of the invention is to provide a cleaning apparatus that is economically efficient.

A second object of the present invention is to provide a cleaning apparatus, in which a head portion has excellent shape retention, firmly stuck dirt can be completely removed, the intimate bonding ability of the head portion to the surface is good. object to be cleaned, and there is no danger that the object to be cleaned will be damaged and the wiping cloth will tear during a cleaning operation.

A third object of the present invention is to provide a cleaning apparatus, in which its user can change the cleaning cloth without the need to grasp the dirty area of the cleaning cloth.

A fourth object of the present invention is to provide a cleaning apparatus, in which a used part of a cleaning cloth can be easily changed to an unused part.

A fifth object of the present invention is to provide a new cleaning cloth, a new cleaning apparatus to which the cleaning cloth is attached, which can be suitably used not only as a duster but also for a cleaning operation.

The first to fifth objects of the present invention indicated above can be achieved with any of the cleaning cloths and cleaning apparatuses according to the independent claims of the present invention described below, or by any of its embodiments described later.

Best Mode of Carrying Out the Invention

Various embodiments of the present invention will now be described with reference to the drawings.

ES 2 175 111 T3 companions.

A typical example of a cleaning cloth according to the present invention is of the type in which non-woven fabrics are joined to form a bonded portion, an insertion space being defined in an internal zone of the bonded portion (bonded portion), thereby forming both a flat bag-shaped configuration as a whole, an unbound portion (unbound portion) having been arranged in an external zone of the united portion.

Thus, the bonded portion in the wiping cloth according to the present invention is preferably constituted as a bonded portion obtained by heat sealing or anaologs. However, the bonded portion is not limited to one bonded portion as long as the nonwovens are bonded to one another, and therefore the bonded portion can be formed by stitching or the like.

The non-woven fabric constituting the wiping cloth is preferably a non-woven fabric composed of a fibrous material having excellent dust-absorbing properties and anti-wear properties. Examples of such a nonwoven fabric preferably include a spun lace nonwoven fabric, a spunbonded nonwoven fabric, a suction nonwoven fabric, a heat bonded nonwoven fabric, a melt blown nonwoven fabric and the like.

The fibrous composition for forming the nonwoven fabric can be suitably selected depending on the method of joining. In case the cleaning cloth is formed by heat sealing the non-woven fabric as described below, it is preferred to use a non-woven fabric made of a polyethylene terephthalate fiber (PET), for example, on the cleaning surface side. and a non-woven fabric made of a PET / polyethylene (PE) composite fiber (core / sheath) is used on the bonding surface side. These non-woven fabrics are preferably obtained by subjecting a polypropylene (PP) fiber to water cleavage by means of a PP net having a lattice-shaped arrangement. In that case, it is especially preferred that the PET / PE (core / sheath) composite fiber, which forms the non-woven fabric used on the bonding surface side, includes 10 to 90% by weight of PE.

The wiping cloth of the present invention can take any shape as long as it can exhibit a flat bag configuration having an insert space. Examples of such a shape are preferably a shape obtained by placing two non-woven fabrics one on top of the other and then sealing them in an area having a predetermined width to thereby form a joined portion, a shape obtained by folding a single non-woven fabric, sealing it afterwards. in other areas having a predetermined width than the folded portion to thereby form a joined portion, and then forming it into a flat bag-shaped configuration having an insertion space that corresponds to the configuration of the head portion. Especially, the arrangement to form the insertion space so that it corresponds to the configuration of the head portion proves to be effective because an entire area of the wiping cloth attached to one attachment portion can be used, with the only exception of one area. near your hole portion.

The way of forming the attached portion is preferably decided depending on what shape the head portion assumes. For example, it is preferred that the end portion includes an angular portion, or the attached portion is formed in a U-shape, V-shape, or anaologous in plan view. Apart from various sealing methods, the bonded portion can be formed by sewing. In case the bonded portion is formed by sealing, the width is made to be 20mm to 0.1mm, and preferably 10mm to 1mm. Due to this arrangement, the desired resistance can be obtained. Acceptable sealing methods include a supersoonic sealing method, a sealing method using a hot melt adhesive, a heat sealing method, and the like. The sealing configuration for forming the portion joined by one of said sealing methods is not particularly limited. The seal configurations preferably include, for example, a continuous, a stripe, dots, and anaologs. In case the linked portion (bonded portion) is formed by sewing, it is preferred to employ an ordinary sewing method using a sewing machine or the like.

According to the invention, the width of the unbonded portion located in an outer zone of the bonded portion is 5mm to 30mm from the peripheral edge portion of the nonwoven fabric. In case the bonded portion is formed by the heat sealing method, if the width is less than 1mm, the object to be cleaned is easily damaged by the bonded or sealed portion. In addition, the unbound portion can hardly exhibit its dust-absorbing effect. In contrast, if the width is greater than 50 mm, the unbonded portion lacks rigidity, making it even difficult to use for cleaning. In case the joined portion is formed by sewing, if the width is less than 1mm, the sewing thread tends to tangle. In addition, the unbound portion can barely exhibit its dust-absorbing effect. In contrast, if the width is greater than 50 mm, the unbonded portion lacks rigidity, making it even difficult to use for cleaning.

It is preferred that the unbound portion is located on an outer side of the attached portion in such a way as to correspond to the attached portion. In case the wiping cloth is formed of two non-woven fabrics as mentioned above, the unbonded portion is arranged on the entire periphery of the wiping cloth except for the area of the hole portion. On the other hand, in case the wiping cloth is formed as a bag of a single non-woven fabric, the unbonded portion is preferably arranged in a part of the peripheral edge portion of the wiping cloth. Although it is preferred that the unattached portion is arranged such that it corresponds to the attached portion, it may be arranged on an outer side of the attached portion. The shape of the outer edge portion of the attached portion is not particularly limited. However, in view of the effective bonding of powder, etc., the shape is preferably a continuous (serrated) cut cheuroon, for example.

IS 2 175 111 T3

The provision of at least one slit in the hole portion of the wiping cloth is effective to achieve easy attachment and separation of the wiping cloth. In that case, the length of the slit is preferably on the order of about 10mm to 70mm.

Embodiments of a cleaning apparatus according to the present invention will now be described.

Throughout the present description, the term "wiping apparatus" refers primarily to "a wiping apparatus to which a wiping cloth is attached", but there are some instances where it refers to "a wiping apparatus in the state in question. that the wiping cloth is not attached (that is, only its obtained appliance portion excluding the wiping cloth of the wiping appliance) ”.

A cleaning apparatus according to the present invention includes a handle having a head portion at its end portion, and a flat bag-shaped cleaning cloth having an insert space. The head portion is usually made of a flexible material.

In the above cleaning apparatus, the cleaning cloth to be attached to the head portion is not limited to the bag-shaped cleaning cloth as long as it can be attached to the head portion. It is preferred, however, to employ the flat bag-shaped wiping cloth of the present invention, with the wiping cloths of embodiments A through D being particularly preferred.

The flexible material constituting the head portion is a porous flexible material in the form of a sponge or flexible rubber-like material having a hardness C of 1 to 60 and preferably 20 to 35. Here, the term "hardness C" refers to to the hardness measured by a type C rubber hardness tester based on SRIS (Japan Rubber Institute specification) 0101. If the hardness C of the flexible material is less than the lower limit of the range indicated above, the end of the head portion, which is easily deformed according to the configuration of an object to be cleaned, is susceptible to fatigue and therefore difficult to remove. Completely dirt, such as dust particles, etc., firmly stuck to the head portion. In contrast, if the hardness C of the flexible material is greater than the upper limit of the range indicated above, the intimate contact with the object to be cleaned is degraded, and a satisfactory cleaning operation cannot be obtained. In addition, the object can be easily damaged and the cleaning cloth can be easily torn during a cleaning operation.

In case the head portion is made of a porous flexible material in the form of a sponge, it is particularly preferred to employ a porous material composed of a soft cellular synthetic resin having excellent durability. As a preferable soft porous material having such above-mentioned properties, for example, a synthetic resin such as a foamed polyethylene, a foamed polyurethane or the like can be enumerated.

In case the head portion is formed of a soft porous material made of a synthetic resin as above, to improve smooth bonding and separation from the wiping cloth, it is preferred that the head portion has a good lubricant. Surface or head portion is subjected to surface treatment so that the color change can be eliminated. As a method to improve a favorable surface lubricant, for example, a Meltome treatment (treatment to improve a favorable surface lubricant), an in-mold coating treatment, or the like can be enumerated. As a surface treatment method for suppressing a color change, for example, an in-mold coating treatment, an anti-yellowing treatment application, coating, or the like can be listed.

As the soft material for composing the head portion, it is preferred to use, for example, a soft cushion-like material obtained by putting a fibrous material such as felt, cotton or the like in a bag made of artificial leather or fabric, apart. of soft porous sponge-like material.

It is preferred that the head portion be tapered such that the thickness of the head portion decreases towards its end portion, or in the direction of its width (for example, the sectional configuration is trapezoidal or like a convex lens ). Due to this arrangement, the reduced thickness end portion or side edge portion is pressed against the corner portion or angle portion so that the wipe can be in intimate contact with it. Accordingly, a corner portion where dirt and dust easily accumulates can be reliably cleaned. Although a lower surface portion (bottom surface portion) of the head portion is preferably flat, it may be partially or totally provided with irregularities.

The shape of the head portion can be appropriately changed depending on which cleaning cloth is attached. It is preferred, however, to use a head portion having an angular portion at its end portion. When the head portion is designed to have the indicated shape, a corner portion and a narrow space can be easily cleaned. In addition, the head portion was tapered in such a way that the thickness of the head portion decreases toward its end portion, or in the direction of its width (for example, the sectional configuration is trapezoidal or like a convex lens). With this feature, a corner portion and a narrow space can be easily cleaned. The head portion can have a predetermined thickness.

It is preferred to arrange a central element within the head portion to apply the desired stiffness to it. This arrangement of the central element within the head portion is especially effective when the head is made of a porous flexible material or flexible cushion-like material.

The shape of the central element can be changed appropriately depending on what shape the head portion assumes. The central element may be integral with the handle body or be located separately from the handle body.

In case the central element is located

ES 2 175 111 T3 separately from the handle body, it is preferred to make the core element of a synthetic resin such as polypropylene, ABS, and polycarbonate, or metal such as stainless steel, and spring steel. In that case, it is preferred to provide an attachment means (eg, male thread member) to attach the central member to the handle body at a lower end portion of the central member.

In case the head portion is made of a flexible porous material or flexible cushion-like material as indicated above, it is preferred that the central element is arranged inside the head portion, but in case the portion head is made of a flexible elastic element such as a rubber, the central element can be omitted.

The provision of the gripping portion to grip the inner surface of the wiping cloth when the wiping cloth is separated from the head portion, in a front portion of the head portion, is effective when the wiping cloth is temporarily released from the head portion in order to use the rear side of the wiping cloth, because the wiping cloth can be easily turned upside down simultaneously when the wiping cloth is separated from the head portion. The shape of the gripping portion is not particularly limited as long as it is capable of gripping the inner surface of the wiping cloth when the wiping cloth is separated from the head portion. For example, a mechaonic hook (for example, "magic tape" from a registered trademark, same below) can be attached to a front portion of the head portion, or a thin plasty plate having a cradle-shaped erected protrusion with one end of the erected protrusion facing rearward, or a thin plastic plate having comb tines as one end with the rear-facing end may likewise be attached. In case the head portion is made of a flexible porous sponge-shaped material, the gripping portion can be formed by forming the head portion using a suitable mold so that the head portion itself can have a protrusion at cradle shape.

The handle portion is preferably designed such that the head portion can be attached to an end portion of the handle portion and a grip portion is disposed at a rear end portion of the handle, the grip portion so that the grip portion is higher than the head portion when the head portion is attached. It is preferred that the handle includes a handle body with a handle portion, and a portion for attachment of the head portion, and that said component parts can be assembled and disassembled.

The handle can be expandable and foldable or not. If the handle is designed so that it can be expanded and folded when the handle is bent or folded in the manner indicated above, it is preferred that the grip portion can be expanded and folded and hooked at a predetermined position, or the portion for the The joint of the head portion is made expandable and collapsible and hookable at a predetermined position.

The handle is preferably made of vinyl chloride, polypropylene, ABS, polycarbonate, aluminum or its alloy, wood, or bamboo in view of light weight, strength and low cost.

The head portion or the handle was provided with a fixing portion to fix thereto the area near the hole portion of the wiping cloth that was attached to the head portion. The fixing portion is designed to be pressed down to the surface of the head portion, so that when the area near the hole portion of the wipe is fixed to the fixing portion, the surface of the area near the the hole portion of the wiping cloth is pressed down from the surface of the wiping cloth which covers the surface of the head portion. The fixing portion was arranged in such a way that when the cleaning cloth is attached for the first time and when the cleaning cloth is attached in its upside down position, it can be fixed in the same portion as the area near the hole portion. cleaning cloth. Due to this arrangement, dust etc. can be prevented from adhering to the area near the hole portion that was attached to the fixing portion. In addition, it can prevent dust etc. from adhering to the fixing portion or jamming when the wiping cloth is fixed again after turning it upside down, and the hand getting dirty or dirty when a cleaning operation is being performed. fixation.
