Description

  The present invention relates to a paper towel storage box dedicated to a paper towel that can easily open an opening for taking out the paper towel, can hardly become wrinkles when taking out the paper towel itself, and can be taken out very easily.

Conventionally, various types of paper towel storage boxes exist. In particular, the folded paper towel has about 20 to about 75 layers stacked in a small storage box, and enters a paper box or box or storage box for hand-wiping or cooking at home or for business use. It is used for business. This paper towel is thicker than tissue paper and is about 25-60 g / m ² (US tsubo) per sheet.

JP 2002-85287 A

  Patent Document 1 discloses a holder (storage box) dedicated to paper towel. However, one side has a perforation a and the other has a crease b so that a horizontal hole is formed in the longitudinal direction of the storage box. It is formed of a cut c and a circular perforation d formed on the side surface. In this case, the perforation d is broken, the semicircle is removed through the cut c, both sides are treated, and the perforation a is broken, and then the guide piece 6 is erected. It can be opened for the first time to form a horizontal hole.

  In this way, there is a generation of dust pieces by removing the semicircular portions on both sides, and there is a work of raising the guide piece 6 immediately after breaking the single line perforation a, which is troublesome. There were drawbacks. Moreover, in the commercially available paper towel storage box, as shown in FIG. 8, perforations are formed in the periphery so that a horizontal hole is formed between the positions inside the storage box in the longitudinal direction.

  In this commercially available paper towel storage box, since the width of the paper towel is larger than the length of the horizontal hole, it becomes a resistance when taking out and not only is difficult to take out, but also has a defect that wrinkles are generated and it looks bad.

For this reason, the problem (technical problem or purpose) to be solved by the present invention can easily open the opening for taking out the paper towel, and can hardly become wrinkles when taking out the paper towel itself. It is to realize what can be easily taken out.

In view of the above, the inventor intensively and researched to solve the above-mentioned problems. As a result, the invention of claim 1 is formed by stacking a plurality of relatively thick paper towels and accommodated as a bundle, one by one on the upper surface of the paper towel. In the paper towel storage box in which a take-out opening is formed, the take-out opening has a central rhombic opening and a longitudinal U-shaped opening at both ends in the longitudinal direction of the rhombic opening. together are formed in the intervals eyes fill direction of the outer shape, the major axis of the rhomboid openings are formed in an appropriate tilt angle in plan view with respect to the longitudinal direction of the horizontal lines of the upper surface, and said end portions A U-shaped perforation is formed at the periphery of the U-shaped opening, and a rhombic perforation is formed at the periphery of the rhombic opening, except for a joint portion with the U-shaped opening at both ends. An outline portion forming the outer shape of the upper surface of the storage box in the U-shaped opening is formed as a crease, and the breaking force of the force to be broken by the fingers of the U-shaped perforation is smaller than the breaking force of the rhombic perforation. The paper towel is formed so that the paper towel can pass through the U-shaped perforation of the end U-shaped opening under the broken state, and the rhomboid opening has a rhombus shape. One side of the diamond shape in the longitudinal direction of the rhombus is formed parallel to the horizontal line in the longitudinal direction of the upper surface, and the other side of the diamond shape is inclined with respect to the horizontal line. In addition, the paper towel is formed to be folded in two or three in a superimposed state, and the upper piece of the uppermost paper towel with the paper towel taken out is always exposed on the rhombic opening. By was paper towel storage box, characterized in Rukoto was solving the problems.

The invention of claim 2, Oite to claim 1, the bonding portion between the rhombic opening portions of the end U-shaped opening was paper towel storage box, characterized in that formed by an arc-shaped Thus, the above-mentioned problem has been solved. According to a third aspect of the present invention, in the first or second aspect, the rhombic perforation is formed as a double perforation by an inner perforation and an outer perforation comprising a cut portion and a connecting portion over the entire circumference, and the U The above-mentioned problems have been solved by forming a letter-shaped perforation as a paper towel storage box formed as a single perforation composed of a cut portion and a connecting portion.

According to a fourth aspect of the present invention, in any one of the first, second, third, fourth, and fifth aspects, the inclination angle of the long axis of the rhombic opening with respect to the horizontal line in the longitudinal direction of the upper surface is 5 degrees to 25 degrees. The above-mentioned problems have been solved by providing a paper towel storage box characterized by being formed each time.

The invention of claim 5 is the paper towel according to any one of claims 1, 2, 3, 4, 5 or 6, wherein the paper towel is formed at 25 to 60 g / m ² per sheet. The paper towel storage box is used to solve the above problems.

  According to the first aspect of the present invention, the opening for removing the paper towel can be easily opened, and when taking out the paper towel itself, there is the greatest advantage that it can hardly become wrinkles and can be taken out very easily. In particular, the opening for taking out the paper towel can be easily performed. In the invention of claim 2, when opening the rhomboid opening, it can be easily hooked on a finger and can be easily opened, and there is an effect that the opening can be easily opened by a child or an elderly person.

  In the invention of claim 3, the opening can be opened in an orderly manner. In the invention of claim 4, the normal type of paper towel can be easily opened over all and the paper towel can be taken out smoothly.

  In other words, because it is thick, it has a rough surface, and when pulling on a paper towel, not only unexpected resistance is applied, but wrinkles are generated, and all the points that tend to give a bad impression to the eyes are eliminated. We were able to. Furthermore, the invention of claim 5 can cope with a thick paper towel very well.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The drawings shown in FIGS. 1 and 2 are a storage box 7 for a paper towel P, which has a rectangular parallelepiped shape. In this interior, dozens (about 20 to about 80) of relatively thick paper towels P stacked alternately so as to be taken out from the upper side in a pop-up manner are accommodated.

  On the upper surface 7A of the storage box 7, a rhombic opening 1 for forming a paper towel P outlet for each sheet, and end U-shaped openings 3, at both ends in the longitudinal direction of the rhombic opening 1, are provided. 3 is formed with full eyes (see FIGS. 1A, 1B, and 2B).

  Specifically, rhombic perforations 2 and 2 are formed on the periphery (except for both ends) of the rhombic opening 1, and the U-shaped perforation 4 is formed on the periphery of the end U-shaped opening 3. Is formed. The rhombic perforation 2 is removed at the start of use, and the rhombic opening 1 for taking out the paper towel P accommodated therein is formed.

  After opening with the rhombic opening 1 and the U-shaped openings 3 and 3 at both ends, the rhombic opening K is formed. At this time, what is important is that, even after the U-shaped perforation 4 of the end U-shaped opening 3 is broken, the outline portion forming the outer shape of the upper surface 7A of the storage box 7 is formed as the fold 43. The remaining end U-shaped opening 3 is retained.

  The major axis N of the rhombic opening 1 is formed with an inclination angle θ as viewed in plan with respect to the horizontal line G of the upper surface 7A. In an embodiment, it is about 5 degrees to about 25. Preferably, it is formed around about 10 degrees.

  Specifically, as shown in FIG. 1 (C), the rhombic perforation 2 is formed on the outer perforation 21 and the inner side over substantially the entire circumference, excluding the joints with the U-shaped openings 3 at both ends. It is formed as a double perforation by the perforation 22.

More specifically, the outer perforation 21 and the inner perforation 22 are both cut portions 21b and 22b. The outer perforations 21 and the inner perforations 22 are formed in the same shape so that the cut portions 21b and 22b of the perforations are arranged in a staggered manner while the connecting portions 21a and 22a are the same. Furthermore, although only the bent portion of the “U” shape side of the rhombic perforation 2 may be formed as a single perforation, the majority is still formed as a double perforation.

  The perforation 4 of the end U-shaped openings 3 and 3 is formed as a single perforation, and is composed of a linear perforation 41 and an arc perforation 42. Both the linear perforations 41 and the arc-shaped perforations 42 are formed as cut portions 41b and 42b and connecting portions 41a and 42a.

  The linear perforation 41 is a portion formed in a straight line while continuing to the rhombic perforation 2, and the arc perforation 42 is particularly a joint portion with the rhombic opening 1. The part is formed in an arc shape. The perforated perforations 41 and the arc perforations 42 are formed continuously.

The force that breaks the perforation when pressed with a finger is referred to as “breaking force” in this specification. Then, the breaking force f of the U-shaped perforation 4 is formed smaller than the breaking force F of the rhombic perforation 2. In other words,
Breaking force f of U-shaped perforation 4 <breaking force F of rhombic perforation 2
Breaking force f <breaking force F
It is formed as. The U-shaped perforation 4 is easier to break than the oblique perforation 2 (see FIG. 1C).

  Accordingly, in FIG. 3, when the end U-shaped opening 3 is pushed with the thumb (see FIGS. 3C and 3D), only the U-shaped perforation 4 is broken, and the rhombic opening The rhombic perforation 2 of 1 is in a remaining state.

In the U-shaped perforation 4, the cut portion 42b of the arc-shaped perforation 42 is provided. Is formed to be extremely larger than the length of the connecting portion 41a so that it can be broken even if the breaking force is slight. That is, it may be more easily broken.

As described above, the rhombic opening 1 is formed by the rhomboid opening 1 and the U-shaped openings 3 and 3 at both ends. It has a shape, and its maximum diagonal opening width is L ₀ [see FIG. 2 (B)]. The maximum opening width L ₀ is a linear interval with an inclination angle θ with respect to the width L _max of the inner side walls 7C, 7C of the storage box 7 in the longitudinal direction.

At this time, as shown in FIG. 4B, the U-shaped openings 3 and 3 at both ends are bent downward, and even if the paper towel P is relatively thick, the opening has a maximum opening width L _0. Is formed. In FIG. 4B, the maximum opening width L ₀ is required to be bent at an inclination angle θ. Here, when the width of the paper towel P and L _0,

The maximum opening width L ₀ is> the inner wall width L _{max in the} longitudinal direction of the storage box 7> the width L _{0 of the} paper towel P
That is, the maximum opening width L ₀ > the inner wall width L _max > the paper towel width L ₀
Since the paper towel P has an oblique opening K having an opening maximum width L ₀ larger than the width of the storage box, when the paper towel P is taken out, there is no resistance to the oblique opening K. It can be taken out smoothly.

In addition, the rhombic opening 1 and the rhombic opening K are simply rhombus-shaped, and are formed with an appropriate inclination angle θ. Not only can the maximum width L ₀ be obtained, but one side of the diamond shape in the longitudinal direction of the rhombus is parallel or approaches, but the other side is inclined, and this inclined side is shown in FIG. In A), as shown on the right side, the paper towel P has a function of extending the tip side upward.

  In addition, as shown in FIGS. 5A to 5D, the rhombus opening 1 may be deformed as the shape of the rhombic opening 1. 5A shows a case where the rhombus is formed thick, and FIG. 5B shows a case where the rhombus is formed thin. FIG. 5C shows a case where the rhombus is formed in a circular arc shape, and FIG. 5D shows a case where the U-shaped openings 3 at both ends are formed larger. In any of the embodiments, functions similar to those in FIGS. 1 and 2 can be exhibited.

  In the embodiment of FIG. 6, the case of FIG. That is, the inclination angle θ of the major axis N of the rhombic opening 1 is formed on the minus side (clockwise) when viewed in plan with respect to the horizontal line of the upper surface. In the embodiment, it is formed at about minus 10 degrees. Even in this case, the same function as in FIGS. 1 and 2 is exhibited.

  In the embodiment, the paper towel P is folded in three. In this case, when the paper towel P is taken out in a pop-up type, the paper towel P is always facing downward as shown in FIG. When folded in an overlapped state (not shown), the upward direction and the downward direction are alternated. In particular, because of the substantially symmetrical rhombic shape, the same effect as in the case of tri-folding is obtained.
