Paper dispenser

0001The invention relates to a dispenser for paper. The Invention particularly relates to a dispenser for paper in the dispenser mounted rollers paper such as toilet paper rolls.

0002Dispenser for paper, in particular toilet paper, are known to where a housing having two opposite Guideways belongs. In the housing, two rolls toilet paper are superposed. The rollers have a cylindrical core made of cardboard, by at the two opposite ends of a Plastic lid is closed. Each cover has a cylindrical Projection which fits in a guideway. This allows the rollers move only vertically in the housing. The lower part is in the Guideways each a stop on either side held, with which the projections are held. The lower End of the guideways is inclined as a stop inside. On Spring arm bears against the side of the lower roll, whereby the core horizontally held. If the role is almost entirely used up, moves the arm over the core, whereby the core can tilt and falls on the bottom of the housing.

0003A major drawback of these known dispensers is that this special, relatively expensive rollers are required, which on both sides with are the aforementioned lids equipped. In addition, this causes relatively large amount of waste. Moreover, the seeds must be separated from the cap are, before they can be discarded.

0004These known dispensers have yet another disadvantage: the continue the roll is unwound, the further pushes the arm the role away, in a position from which can tilt from the core, whereby the Unwinding of the paper is difficult, and the probability that the roller is inadvertently pulled out of the housing increases.

0005The invention has the objective of a donor in the introduction to provide the type described, wherein at least some of the above Disadvantages are avoided.

0006The invention has in particular the objective, such a dispenser to provide that with conventional rolls of paper with a hollow cylindrical Core can be used.

0007The invention further has the objective of such a dispenser to creating, in which the position of a roll, is unwound from the paper, obtained during use with respect to guideways and remains in which stops are required below the guideways not.

0008The invention further has the object to provide a dispenser is universally applicable, with rolls of paper with different Diameters.

0009At least some of these and other objectives with a Dispenser according to the invention, by the features defined in claim 1 is characterized achieved.

0010When a dispenser according to the present invention, the roll, ie the lower roller, supported by a holding role. The role is horizontally sandwiched by the two guideways. The or each Retaining roller is mounted so that the role of the or each retaining roller can not move over before almost all paper has been removed from it. On the role only vertical forces act essentially, particular gravity. This is the role always in a desired position between the two guideways held. Preferably, moreover, is a collection container for the seeds and any Axes on which the cores, ie rolls are supported in the housing, available. This will prevent that the latter or to the ground, covered at least from the housing and start inadvertently lost or be discarded. Thus, contamination of the environment of the Donor prevented in a simple manner.

0011In this way you get a donor whose construction and Use are particularly simple and in which, moreover, different Roll formats can be used.

0012In a favorable accurate preparation itself features a Dispenser according to the invention further by the measures in Claim. 2

0013The immediate release of the collected in the collecting vessel Cores and possibly axes when opening the case is prevented, that axes or nuclei in the collection container remain. This could lead to clogging lead. Moreover, it simplifies the separation of eventual axles and cores from each other.

0014In a more specific embodiment, low-removable Axles mounted on which the rollers are supported in the housing; these axes have been inserted for this purpose through the cores. This is preferably done in such a way that the rollers during use, the housing and the holding roller or adapt such catching mechanism. The axes thereby determine the Journal for inclusion in the guide tracks. In such a Embodiment, it is particularly advantageous if the collecting container is appropriate, because the axes can then reuse are collected after the nearly empty cores from them were.

0015Into the housing may preferably be at least two rollers Paper are superimposed added. These roles are preferably separated by arresting one another, which to be Example partially into at least one of the guideways and are represented by the presence or absence of a roll in a lower actuated position, ie in the position in which one of the outside Dispenser for removing the wound thereon paper on the role zoom comes. If the lower roller sufficiently and preferably has been completely used up, which means that the core is empty or nearly empty, it falls from the guide tracks and the Locking to be released so that an overlying roller in may drop the aforementioned lower position. If it still third roller is present, it is up to the locking with by below, so that this third roller in turn at a certain distance is kept to be lower roller. In this way, an undesirable Friction between the rollers is prevented.

0016When a dispenser according to the present invention is the The housing preferably is shaped and dimensioned such that in the housing at least two rollers with a diameter of 120 to 150 mm, more specifically about 140 mm, above the other match, but also at least three Rollers having a diameter of 90 to 120 mm, more specifically from about 100 mm, one above the other, wherein the upper roller or upper rollers always without Contact of the lower roller in a with regard to the diameter of the Roles are relatively small distance, for example a few millimeters.

0017In a dispenser with a collecting container according to the invention is the Collecting container preferably tiltably connected to the housing, on such a way that when opening the case of the collection container so tilts that seeds or axes are immediately accessible and preferably falls under the influence of gravity from the holding tank. It is it is advantageous, if the parts of the housing and the collecting container remain connected. The housing can, for example, to have a rear portion, the one on a wall or on appropriate suspension or equivalent Aufhängefläche can be attached, and a front part, which is pivotally connected to the rear part and between a can move open and closed position. In this case, the front part connected to the rear part on the collecting container be pivotally connected to at least one of these parts, and preferably is connected to both.

0018The invention further relates to an assembly of a dispenser for paper, particularly as described as above, and a collecting container detachably with the underside of the is dispenser connected or can be connected. This allows the Collecting vessel used, as desired, along with the donor be or not.

0019Preferably, the receptacle is a container part interchangeable, in which a stack of paper can be taken in Housing. The container part is provided with means for the metered removal of Equipped paper from the stack above or it forms this during use together with the housing. The stack of paper is preferably a per se known stack of relatively Z or V-shaped, partially intermeshing folded paper, as and in Towel The like is used. In this way, with the same case both created a dispenser for paper rolls as well as folded paper be what is technically and economically favorable, and moreover resulting in a uniform and pleasant appearance.

0020The invention further relates to a container part for such a Donor, ie, for a number of donors. With such a container part can be an existing dispenser for rolls of paper just for delivery Change of folded paper. Of course, for the conversion a dispenser for folded paper in a dispenser for paper rolls on Correspondingly, a collecting container are attached.

0021The invention further relates to a compilation according to claim eleventh

0022Such compilation offers the advantage that with same donor both roles of the famous model with an on both sides open, hollow cylindrical core and the rollers known model with an end cap on each side of cylindrical core can be used. This is economically low, because it reduces the different parts are required, because the be donors always filled in the same manner, emptied and maintained can and because, moreover, a uniform appearance for different Dispenser is achieved. A user can thus easy for everyone Donor to decide what kind of roles to be used in it and he can do this even change to a later date or change leave.

0023Here preferably a container part as described above provided, mounted on or in a lower end of the dispenser can be, so that it no longer paper roll, but for folded pieces of paper is suitable. This is the freedom of choice for User with a minimum of additional parts to the manufacturer and the user is further increased.

0024The invention further relates to a number of donors, the be characterized by the measures according to claim. 13

0025One such series contains at least two of the above three Donor models, and preferably all three. This is for a User reaches optimum freedom in the choice of donor models, which donors jointly provide a unified vision and can also be produced economically and wait.

0027The embodiments illustrated in the drawings are merely to illustrate and should not be construed as limiting. In this description the same or corresponding parts have the same or corresponding reference numbers. This description is a "top" a up during use overhead part of the dispenser, in Fig. 1 shown in the drawing.

0028Fig. 1 shows in side cross-section schematically a dispenser 1 according to the invention, with it two paper rolls 2, in particular toilet paper. These roles have 2 in full condition, for example, a diameter D_Gof about 140 mm. The dispenser 1 has a housing 3, the rear of a Part 4 and a front part 5 is made. The rear part 4 is in a Rear wall 6 in a manner known per se with suspension means for equipped attachment to a wall or the like, for example with Openings for hooks or screws. The rear part 4 has two Side walls 7, in each of which a guide track 8 is. Each Track 8 includes a first, upper portion 9, which extends approximately perpendicular extends, or at least approximately parallel to the rear wall 6, and a lower Portion 10 which is inclined at an angle α to the rear wall. 6 The lower end 11 the lower part 10 is open downwards. The upper part 9 is at the top End 12 is also open. This top 12 is a slightly enlarged Mouth 13 (Fig. 4) for facilitating the feed and for storing three Rollers 2 have, as will be discussed in more detail.

0029In the illustrated dispenser 1 rolls 2, according to the Representation in Fig. 7A are used with a hollow cylindrical Core 14, for example of paper or cardboard, wrapped in paper 15, which core 14 at both ends open. From the core 14 projects in this Embodiment an axis out 16, the one on both sides of the roller protruding pins 17 is determined. The axis 16 is made even closer to descriptive reasons preferably with little scope from the core 14 surround. Fig. Figure 7B shows a second embodiment of a roll 2, in the can be mapped to the dispenser 1 used. This type of roller 2 is referred to as "lid part" and also includes a core 14, which is surrounded by the paper 15, wherein in the core 14 on both sides of a Plastic lid was placed 18 in the core 14th Each cover 18 determines a pin 17, comparable to the removable axles 16. The distance L between the free ends of the pin 17 was used for the two types of rollers 2 almost equal chosen.

0030have in the embodiments shown in Fig. 7A and 7B the pins 17 on both sides of the roll 2 a different Diameter. On the drawing on the right of the pin has a smaller diameter R₁ as the left, where the diameter R₂ is slightly larger. The Guideways 8 in the dispenser 1 have been adjusted to the effect that any Role 2 only in a single position between the side walls 7 can be included, with the pins 17 in the guide tracks eighth This has the advantage that the correct unwinding of the roll reaches becomes. Just as you can of course other solutions select, in which the pin 17 also have the same diameter can.

0031The rear portion 4 is in the vicinity of a lower end having an axis 19 fitted to the the front part 5 can rotate between a closed position (fig. 1) and an open position (Fig. 3). In the Close to the front underside of the front portion 5 is a Recess 20 on both sides of an opening 21 in which a collecting container 22 has been suspended by means of two pins 23rd The collecting container 22 has a Bottom surface 24 and two side wall parts 25, to which side wall portions 25 the pins 23 are attached. In the bottom surface 24 is a Recess, which forms the opening 21 for removal of paper. Of the lower part of the collection container 22 is closed Bottom wall 24 is formed and is almost fully open at the back of the 26th In at least one side wall 25 is located a cam 27, which at Closing the dispenser behind a detent 28, for example at or about axis 19, can hook to the collection container in the in Fig. 1 and 2 keep position shown.

0032In the vicinity of the lower end of the dispenser is in the vicinity of the Axis 19 a retaining roller 29 is attached, which is between the two Sidewalls 7 extends and preferably free or somewhat slowed their can rotate the longitudinal axis (perpendicular to the drawing plane). These Retaining pin 29 extends approximately the same level as the free end 11 of the the lower part 10 of the guideways. 8

0033A dispenser 1 according to the invention may, for example, are used as follows. The front part 5 is rotated about the axis 19 pivoted to the open position, see Fig. 3. Then, a Role 2 in a suitable manner from the open top end 12 of the pin 17 brought into the guideways. 8 The role then drops down in the guideways 8, down to the lower part 10. In this case, without prejudice to the Outside 30 of the reel 2, the holding roller 29, see Fig. 1, 2 and 4. The pin 17 are thereby located near the transition between the first and the second part 9, 10 of the guide rail 8. Thereby, the roller 2 in the lower position included.

0034At least one side wall 7, a tilting element 31 is present, the about a tilting axis 32 in a plane approximately parallel to the side wall 7 is, can tilt. The tilting element 31 comprises a first arm 33 of the Tilt axis 32 and an overlying second arm 34. The first Rocker arm 33 can extend into the lower part 10 of the guide track, see Fig. 3, while the upper rocker arm 34 fitted with a projection 35 is capable of 8 rich in the top 9 of the guide path, see FIG. 1. Possibly, the upper rocker arm 34 to adapt them to different have roll diameter over several such projections 35, See Fig. 4. Fig. 1 shows that the first arm 33 by the pin 17 of the lower roll 2 from the lower part 10 of the guide path 8 is pressed, whereby the projection 35 of the second rocker arm 34 in the upper part 9 is pressed. Subsequently, a second roller 2 from the open top End be brought out into the guideway 8, the role of the above said projection is resting 35th Preferably, at both The donor's such a tumbler.

0035After both rollers 2 (or as shown in Fig. 3, three reels 2) one above the other were placed in the dispenser 1, can the front part 5 in the closed Position are pivoted, with suitable (not shown) Closing devices have been attached to complete the donor. As 1 and 4 clearly show Fig., The tilting element 31 such that the held upper roller 2 at a small spacing Z from the lower roller 2 is such that friction is prevented.

0036From the roll 2 in the lower position of paper 15 can be obtained by the Except port 21 are processed, whereby the diameter D_G of the Roll 2 decreases. Consequently, moves the pin 17 under the action of gravity or at least through the lower part 10 of the Guideway 8, the open end 11 towards, while the outer surface 30 with the retaining roller 29 keeps in contact. The distance from the holding roller 29 up to the open end 11 has been chosen so that when (almost) everything from paper 15 Core is unwound 14 of the lower roll 2, the pin 17 accurately in the open ends 11 of the guide tracks 8 are, which then, and only then, the core 14 may move past the retaining roller 29, so that the Pin 17 come out of the guide tracks 8, through the open ends 11 and drop the cores 14 downward into the receptacle 22, see FIG. 2. At the same time occurs, the first arm 33 of the tilting body 31 into the lower part 10 the guide track 8, whereby the projection 35 of the other arm 34 of the upper part 9 is pulled out from under the pin 17 and the upper roller 2 may fall into that shown in Fig. 2 position, which by the opening 21 of paper may be unwound from the roll. Of the Tilting body 31 can be biased in the position shown in FIG. 3.

0037As a result of the fit of the core 14 about the axis 16 has positioned itself Role always work properly in the dispenser at the holding roller 29, so that they are not can move on the axis.

0038In Fig. 7A, the gap between the axis 16 and the core 14 exaggerated. Preferably this is about sliding, so that relatively little movement of the core 14 with respect to the axis 16 is possible. This can be precisely controlled so that the core 14 really only then move past the retaining roller 29, when almost all paper from 15 the roller 2, ie, the core 14 is removed.

0039After the two rollers 2 are used up and, therefore, both Cores 14 are in the receptacle 22, or to a control appropriate time, the dispenser 1 are opened, see FIG. 3. The front section 5 is tilted about the axis 19, the cam 27 is pulled by the catch 28 and the catch tank 22 tilts about the Pins 23, in such a way that the open back 26 tilts downwards. The 14 cores covered by downward from the holding tank 22, see Fig. 3. These nuclei can be collected and discarded or Recycling will be prepared. can then use the above mentioned manner again two rollers 2 are mounted in the dispenser 1, the reuse.

0040Fig. Figure 4 shows that in the same donor and three rollers 2 one above the other can be mounted, which rollers, for example a smaller diameter D_k may have, for example, about 100 mm. to roll 2 with diameters of 100 and 140 mm are known per se, commercial roles toilet paper. Of course, a dispenser 1 according to the Invention will be made suitable for other roll diameter. Fig. 4 shows a small variation to the guideways 8, wherein the upper End 12 has a slightly enlarged mouth 13, whereby the upper part 2 can be applied to the rear wall 6 very close, so that the donor as shown in Fig. 4 can have the same shape and the same dimensions as the dispenser according to Fig. 1. Of course, according to also in the dispenser Fig. 1 of the above-mentioned expanded mouth 13 are attached. The Dispenser 1 according to fig. 1 and 4 are preferably in respect to construction, Dimensions, material use or external appearance identical so that choice of two rollers with a diameter of, for example, about 140 mm or three rolls having a diameter of about 100 mm in the dispenser 1 can be taken.

0041However, Fig. 5 shows the same dispenser 1 according to Fig. 1 or 4, wherein the receptacle 22 has been removed. This is easily possible by the Pins are taken 23 from the recesses 20 after donor 1 was opened (see Fig. 3). In this embodiment, preferably in particular cover rolls 2 used, see Fig. 7B; after everything was settled paper of this cover rolls fall freely from the dispenser 1 and can be thrown away, for example in a Trashcan.

0042If according to the invention rollers 2 with a dispenser 1 a removable axis 16 are used, see Fig. 7A, preferably a collecting container 22 is used, so that both the cores 14 and the axles 16 are collected in the collecting container 22nd At the Open the dispenser 1 are then the axes 16 from the cores 14 taken and put in new rollers 2, so that the axes 16 again be used. The cores 14 are preferably discarded. If Rollers 2 are used seedless 14, then of course Only the axes 16 collected.

0043Fig. Figure 6 shows a side cross section of the same dispenser 1 according to for example Picture 1 - 5, but the collection container 22 by a container portion 40 has been replaced, the place of the collection container 22 in the Bottom 41 has been hooked. For this purpose, the container part 40 can, for example, be hung on the axle 19 and (not shown) having pins 23 corresponding to those of the collecting vessel 22 as shown in Fig. 3 at the front part 5 are suspended. Nevertheless, the container portion 40 can of course fastened in a different manner in the lower end 41 of the dispenser 1 are, preferably at least on the rear part 4. In the container part 40 there is an opening 21A in the depicted embodiment, in a lower wall portion 42 thereof. Nevertheless, such an opening 21A could also at least partly in the front wall 43 of the container part 40 to be appropriate. On the lower wall 42 of the container part 40, a Stack 44 paper 15A worn, known as a stack per se, fan-fold paper towels or toilet paper pieces. In the in Fig. 6 illustrated, closed state can through the opening 21A always a bottommost piece 15B paper from the stack 44 are pulled, whereby again a new piece 15B is ready for gripping.

0044As clearly shown in the drawings, the invention comprises a Number of donors 1, which for rollers 2 and folded stack 44 paper are suitable or can easily be made suitable. The Dispenser 1, at least the rear part 4 and the front part 5 can be used for all Embodiments of the same, when both the manufacturer and for the User is particularly favorable. Moreover, simply, a donor from a Model are converted to the other and vice versa. When using the Dispenser according to the invention, both rolls with a relatively small diameter D_k as well as having a relatively large diameter D_Gbe used both with removable axles as well as with Covers, wherein if desired the cores in a collecting vessel be collected or can be removed directly from the dispenser.

0045In the illustrated embodiment, the housing has a relatively flat back wall 6 and a curved front wall 45 of the This front portion curved front wall is 5. 45, in particular Fig. 1 and 4 are bent so that both the large and the small rolls 2 fit exactly into the dispenser. 1 It should, however, clearly be that other shapes for a dispenser 1 according to the invention can be used.

0046The invention is not restricted to those in the Description and shown in the drawings embodiments. Within the scope of the claims set out by the invention are many Variants thereof possible.

0047Such other locking means may be used around the rollers in keeping donors at bay, for example, manually operated Locking. Variations on such arresting are from practice well known. The holding roller 29 could in another way be mounted, or in another position, for example near of the opening 21, while this, for example, as two rollers near the two long walls could be performed 7 or as individual role is supported by the rear wall. 6 There are many variations possible to and they will be the skilled worker immediately clear. The lower part 10 of the Guideway 8, could also extend vertically or forward, with the holding roller 29 according to another suitable position could be mounted in such a way that the roller 2 in the lower Position would thereby supported in the manner already described. there can be prevented that the cores 14 pass through the opening 21, by the opening narrower than the length L makes between the free Ends of the pins 17. Even then the cores 14 and the axes 16 are on Desire in the collection vessel 22 is collected. Depending chosen by the Dimensions of the rollers 2 and the donors 1 can of course also other numbers rollers are received therein.

0048These and many comparable variations are considered within the scope of by the claims set forth the invention.
