Description

The present invention relates to an attachment for a paper towel dispenser. Further, the present invention relates to an attachment for a paper towel dispenser for attaching to a paper towel dispenser to accommodate paper towels of different standard sizes.

A well-known paper towel dispenser is a bundle of paper towels that is made by folding and stacking multiple sheets of paper towels, which are interchangeably stored inside and pulled out one by one from the outlet. The structure of this type of paper towel dispenser is represented by the structure shown in FIGS. 4 to 7. That is, the paper towel dispenser 101 is formed with a front plate portion 111 that also serves as a lid portion of the dispenser and an elongated outlet 110 on which a bundle 102 of paper towels is substantially placed and extends in the width direction in the central portion in the front-rear direction. It has three elements, a bottom plate portion 113 and a back plate portion 112 located facing the front plate portion 111. In some cases, the back plate portion 112 and the bottom plate portion 113 are integrally formed.

Further, in this type of paper towel dispenser 101, the paper towel is often used for hand-wiping after hand-washing, so that the water after hand-washing does not fall and invade from the take-out port 110 and contaminate the internal bundle. Since it is required to be installed in a relatively narrow space such as a washroom or a restroom, an outlet 110 is formed on the bottom surface, and the outlet 110 is directed downward via the back plate portion 112. Often installed on the wall.

By the way, there are multiple sizes of paper towels. For example, there are some differences in the names and sizes of each type, such as large format, medium format, small format, S, M, L size, small size, medium size, and large size, but there are about 3 standards. It is divided into the sizes of. In recent years, the quality of paper towels has been improved to improve functions such as water absorption, and from the viewpoint of increasing eco-consciousness and reducing waste, consumers who used large-sized or medium-sized paper towels, for example, have been using paper towels. There is a shift to paper towels with smaller paper surfaces such as oval paper towels, and their consumption is increasing.

On the other hand, many of the conventional paper towel dispensers 101 are made exclusively for the size of the paper towels for large format, medium format, small format, etc., and these conventional paper towel dispensers 101 are used. It is easy to pull out the paper towel from the paper towel bundle 102, which is suitable for the size of the paper towel bundle to be assumed. For example, as shown in FIG. 6, the shape of the bottom plate portion 113 having the outlet 110 is the size of the bottom surface of the bundle 102 of paper towels, which is called medium size or medium size (generally short side 115 to 125 mm × long side 210). It is preformed according to (~ 230 mm), etc., so that the bottom portion of the paper towel bundle 102 does not excessively accumulate in the outlet 110 at the time of withdrawal, making it easy to pull out the paper towel 101S (note that a large-sized bundle or the like). For example, the size of the bottom of the paper towel is approximately 115 to 125 mm on the short side x 240 to 260 mm on the long side).

However, as shown in FIG. 7, in the paper towel dispenser 101 adjusted to the size of such a medium format, the size of the bottom surface is small (generally short side 80 to 100 mm × long side 210 to 230 mm), oval or small. When a bundle of paper towels 102x, which is called a size, is used, the bottom of the bundle of paper towels 102x is densely packed in the take-out port 110, the resistance to take out the paper towels is excessively increased, and problems such as tearing of the paper towels occur. Further, especially when the number of paper towels constituting the bundle is small, there arises a problem that a plurality of paper towels fall from the opening at once.

In this way, when consumers who used to use large-sized or medium-sized paper towels to switch to small-sized paper towels, it is necessary to purchase a new paper towel dispenser and replace it. There is a burden of cost and labor. It can also hinder the transition from larger paper towels to smaller paper towels.

On the other hand, although it is not intended to change the size of the paper towel, Patent Document 1 below discloses a plate-shaped attachment that is elastically deformed and installed in a dispenser to enhance the pullability of the paper towel.

Since the attachment described in Patent Document 1 is elastically deformed and installed, there is a problem that the size cannot be changed depending on the shape of the dispenser to be installed. Further, since the shape of the dispenser inevitably determines the shape after elastic deformation, it may not be possible to finely change the shape due to the difference in the paper quality of the paper towel, and the smooth take-out performance may not be sufficiently exhibited. Further, there is a problem that it can be attached only to a dispenser having an internal shape that can maintain an elastically deformed state. Further, depending on the dispenser, there is a problem that the effect may not be sufficiently exhibited because the outlet of the attachment does not match the outlet of the dispenser at the time of attachment.

It is a front view of the paper towel dispenser of the conventional example. It is a side view of the paper towel dispenser of the conventional example. It is sectional drawing for demonstrating the mode to put a bundle of the medium format paper towel in the conventional medium format paper towel dispenser, and use it. It is sectional drawing for demonstrating an aspect when a bundle of small-sized paper towels of a smaller size is stored in the conventional paper towel dispenser for medium format, and is used.

Next, embodiments of the present invention will be described in detail below with reference to FIGS. 1 to 3.

The paper towel dispenser attachment (hereinafter, simply referred to as an attachment) 20 according to the present embodiment is attached to the inner and lower portions of the paper towel dispenser 1, and has a smaller size than the paper towel of the size originally assumed by the paper towel dispenser 1. It is an attachment that allows you to pull out smoothly to the end even if you use the paper towel of. Specifically, a paper towel dispenser 1 for a paper towel having a relatively large paper surface called a large format, a medium format, a large size, a medium size, etc., and a paper towel called an oval or a small size having a smaller paper surface than the paper towel dispenser 1. It is an attachment that allows you to pull out smoothly to the end even if you use it. The paper towels may be 1 ply or 2 plies or more and may be a set.

The attachment 20 according to the embodiment is formed by bending a single plate-shaped material that can be bent and molded. The shape of the outer edge of the attachment 20 before bending is not necessarily limited, but is preferably substantially rectangular, and the length in the width direction is shorter than the length in the width direction in the attached paper towel dispenser. The length in the depth direction may be longer or shorter than the length in the depth direction in the attached paper towel dispenser, but a longer length is desirable because it is easier to adjust the angle described later.

The attachment 20 is preferably strong enough to be bent by a human hand, and is plastically deformed by bending and can retain its deformed shape. Further, it is desirable that at least the surface of the attachment 20 in contact with the bundle is smooth. Further, the attachment 20 may have flexibility. Specific examples of the material of the attachment 20 include resin plate materials such as polypropylene, polycarbonate, and polyvinyl chloride, corrugated cardboard, and coated cardboard having a basis weight of about ^{250 to 500 g / m 2.} Among them, a polypropylene resin plate having a thickness of 0.5 to 1.0 mm is particularly suitable from the viewpoints of cost, bendability, strength and flexibility after assembly.

The attachment 20 has an opening 30 having an elongated portion 31 extending in the width direction of the paper towel dispenser when attached to the paper towel dispenser 1. The opening 30 is located at the top of the outlet 10 formed at the bottom of the paper towel dispenser 1 at the time of attachment, and the resized paper towel is discharged from the outlet 10 of the dispenser 1 through the elongated portion 31. NS. Therefore, the shape of the elongated portion 31 in the opening 30 is appropriately designed according to the shape of the bottom surface of the paper towel bundle 2 after the size change. When the elongated portion 31 is narrower in the depth direction than the elongated portion extending in the width direction of the outlet 10 of the paper towel dispenser 1, the elongated portion becomes a substantial ejecting portion of the resized paper towel. .. In this case, since the length L1 of the short side of the bottom surface of the bundle 2 of paper towels called oval, small size, S size, etc. is about 87 mm, in these cases, the opening width L2 of the elongated portion 31, It is preferably 15 to 20 mm. The length in the width direction may be 180 to 210 mm.

Further, the opening 30 of the attached attachment 20 shown in the figure has a recess 32 facing in the depth direction at a position at the center of the paper towel dispenser 1 in the width direction at the time of attachment. The recess 32 is preferably formed on the side that is on the front side in the depth direction when the paper towel dispenser is attached. The presence of the recess 32 makes it easier to pick the bundle of paper towels 2 when attached to the paper towel dispenser 1. The size of the recess 32 and the like may be appropriately designed according to the size and the like of the bundle 2 of the paper towels.

On the other hand, the attachment 20 has easy bending lines 40A, 40B, 41, 42 for plastically deforming the attachment 20. A pair or more of the easily bent lines 40A, 40B, 41, 42 are formed in the depth direction with the elongated portion 31 interposed therebetween. Further, the elongated portion 31 extends linearly along the extending direction. In the illustrated form, the easy bending lines 40A, 40B, 41, 42 have one on the depth side and three on the front side of the elongated portion. It should be noted that the one divided by the recess 32 is counted as one.

For the easy folding lines 40A, 40B, 41, 42, for example, a known configuration that facilitates bending along the line such as a folding line, a half-cut line, a squeezing line, or a perforation line can be adopted. As long as the material itself is easy to bend, it may be simply a line attached by printing. When the material is a resin plate, squeezing wire is suitable.

As shown in FIGS. 2 and 3, the attachment 20 is bent at the easy bending lines 40A, 40B, 41, 42 so that the elongated portion 31 of the opening 30 is located at the lowermost end, and the easy bending lines 40A, It is attached to the lower part of the inside of the paper towel dispenser in a state where an inclined surface inclined in the depth direction is formed from 40B, 41, 42. A more specific mounting mode may be appropriate, but for example, the paper towel dispenser 1 is placed on the bottom plate portion 13 on which the paper towel bundle 2 is placed, and is fixed at an appropriate place with an adhesive or an adhesive tape. And can be attached.

The angle when bent is preferably 10 to 70 °. That is, it is desirable that the plate-shaped material and the easily bent line can be plastically deformed at an angle of 10 to 70 °.

Here, the length L3 between the pair of easy folding lines 40A and 40B closest to the elongated portion 31 in the attachment 20 is appropriately adjusted according to the length in the depth direction on the bottom surface of the resized paper towel bundle 2. It may be designed, but it is desirable that the length is at least shorter than the length in the depth direction of the bundle. If the bottom surface of the bundle 2 of paper towels is entirely placed between the pair of easy-folding lines 40A and 40B and the entire surface is in contact with each other, the improvement in pullability by the attachment 20 may not be exhibited. Preferably, the length is 50 to 80% of the length in the depth direction on the bottom surface of the bundle. With this length, when the bundle is placed from the bending direction after being bent by the easy bending lines 40A and 40B, the bundle is appropriately bent and the pullability is improved. Since the length L1 of the short side of the bottom surface of the bundle 2 of paper towels called oval, small size, S size, etc. is about 87 mm, in these cases, the pair of easy folding lines 40A and 40B The length between them is preferably 44 to 70 mm. The length between the elongated portion 31 and the pair of easy bending lines 40A and 40B may be such that the elongated portion 31 is located in the central portion between the pair of easy bending lines 40A and 40B. .. Further, it is desirable that the angle X by bending the pair of easy bending lines 40A and 40B is 130 to 180 °. The paper towel at the bottom of the bundle becomes slippery on the slope.

The number of easily bent lines in the attachment is not necessarily limited, but due to the size of a general dispenser and the like, the upper limit is about 6 lines in total of 4 lines in addition to 1 to 2 lines. If the number is 6 or more, it becomes difficult to bend at the intended angle, and the selection of lines becomes complicated.

On the other hand, as shown in the illustrated form, the easy-folding lines in the attachment 20 are, in addition to the pair of easy-folding lines 40A and 40B close to the elongated portion 31, an additional 2 on any side of the elongated portion 31 in the depth side direction. It is desirable to have ~ 3 (2 in the figure, reference numerals 41 and 42). In the attachment 20 having a total of 4 to 5 easily bent lines 40A, 40B, 41, 42 in such a form, the following shape deformation is possible and the effect is exerted. That is, it is possible to form the bending of the bundle 2 of the paper towels by bending and angling the pair of easy folding lines 40A and 40B close to the elongated portion 31 to improve the pullability. In addition, by angling the other 2-3 easy bending lines 41, 42, the absolute depth length L4 of the attachment 20 can be adjusted and determined and attached to paper towel dispensers with different internal depth widths. It becomes possible. Further, the elongated portion 31 of the opening can be positioned directly above the paper towel dispenser outlet 10 by angling the other two or three easily bent lines 41 and 42. The pair of easy-folding lines 41 and 42 other than the pair of easy-folding lines 40A and 40B, which are particularly close to the elongated portion 31, are located on any side of the elongated portion 31 in the depth side direction. Installability and usability are improved. Since the paper towel dispenser 1 is used by hanging on a wall, the front plate portion can be opened by a pull-down type or a pull-up type so that a bundle can be added inside. In particular, the bundle can be placed on the bottom plate portion with the front plate portion 11 open. Therefore, if two or three easy-folding lines other than the pair of easy-folding lines are in the depth side of the elongated portion, the adjustment angle of the other two or three easy-folding lines is the back plate portion 12. Alternatively, since it can be determined in relation to the front plate portion 11, the position of the opening with respect to the outlet can be kept at an appropriate position.

As described above, the attachment 20 according to the present invention can smoothly take out a paper towel having a smaller paper surface without replacing the paper towel dispenser 1, and can be attached regardless of the type of the dispenser.

As an example of the attachment of the present invention, an attachment 20 having an opening and an easily bent line having the shape shown in FIG. 1 formed on a polypropylene plate having a thickness of 0.7 mm was produced. Two types of attachments were prepared, one having an elongated opening width L2 of 15 mm and the other having an opening width L2 of 19 mm. The length of the elongated portion in the width direction was 182 mm for the 15 mm portion and 188 mm for the 19 mm portion. The length L3 between the pair of easily bent lines near the elongated portion of the opening is 60 mm.

This attachment 20 was attached to different medium format paper towel dispensers manufactured by companies A to D, and the pullability of a bundle of oval size paper towels was confirmed. Regarding the attachment, the slender part of the opening was bent with an easy bending line so that it was directly above the outlet of the paper towel dispenser. The attachments 20 attached to each company have the same configuration except for the angled line at the easy bending line.

As for the pullability, it was confirmed that the seat was dropped and the seat was torn. The paper towel used for pulling out was a 2-ply set that was prone to sheet drop. For this sheet drop, the number of pairs of paper towels that were unintentionally dropped from the take-out port when withdrawing was counted, and for the sheet tearing, high resistance was applied during withdrawal, and the number of pairs of paper towels that could be partially torn was confirmed. It should be noted that the number of sets of paper towels dropped at the same time is also counted, especially when the number of sets constituting the bundle is reduced.

In addition, the sheet drop was verified using one bundle of 200 sets, and the sheet tear was verified using three bundles of 200 sets. The paper towels are a 2-ply set with a basis weight of 16 g / m ² (Eliere Paper Towel Smart Type Double Oval 200 pairs (400 sheets)) and a 2-ply set with ^{a basis weight of 18 g / m 2} (Elver Paper Towel Eco Double Oval 200). We went with two kinds of sets (400 sheets). In Table 1, a 2-ply set of ^{16 g / m 2} is designated as A, and a 2-ply set of ^{18 g / m 2 is designated as B.}

We also tested the case where the attachment was not attached for verification. The results are shown in Table 1 below.

As a result of the evaluation, even if the attachment has the same shape, it can be used with different paper towel dispensers, and by attaching the attachment, the sheet drop was improved in each step. Regarding sheet tearing, some attachments with an elongated opening width L2 having a size of 15 mm were torn more than those without attachments, but this is sufficient for general use. Further, when the opening width L2 of the elongated portion is 19 mm, it is sufficiently improved.

The present invention is not limited to the above embodiment, and various modifications can be made within the scope of the present invention.
