Description

  The present invention relates to a household thin paper storage box.

Recently, for example, household thin paper storage boxes that are used by laminating household thin paper such as tissue paper and storing them inside and taking out the household thin paper stored through the opening provided on the upper surface are used by consumers. However, in order to make it easier to carry a household thin paper storage box and not take up a storage space, downsizing in the thickness direction is proceeding (for example, see Patent Document 1).
With the downsizing of the household thin paper storage box in the thickness direction, the length in the longitudinal direction of the outlet formed on the upper surface of the household thin paper storage box is manufactured in order to improve the removal properties of the household thin paper storage box. Measures are taken to make it as long as possible.
On the other hand, the width and length dimensions of the household thin paper storage box are larger than the dimensions of the household thin paper to be stored, and there is a gap when the household thin paper is stored inside the household thin paper storage box. It was.

JP 2001-286414 A

However, in the conventional household thin paper storage box, the household thin paper in the household thin paper storage box is biased inside due to the above-described gap. Along with downsizing in the thickness direction, household thin paper is packed in the thickness direction, so when pulling out household thin paper in a biased state, the frictional resistance increases and the household thin paper is easily torn. There was a problem.
For such a problem, for example, it is conceivable to prevent the bias of the household thin paper in the household thin paper storage box by reducing the size in the width direction and the length direction of the household thin paper storage box, The length in the longitudinal direction of the take-out port formed on the upper surface of the household thin paper storage box may be shortened, and the take-out property may be deteriorated.

  Hereinafter, a household thin paper storage box according to an embodiment of the present invention will be described in detail with reference to the drawings. However, the scope of the invention is not limited to the illustrated examples.

(Embodiment)
As shown in FIGS. 1 to 5, the tissue carton 1 that is a household thin paper storage box according to the present embodiment includes an upper surface portion 2, a bottom surface portion 3, a pair of side surface portions 4, 4, and a pair of wife surface portions 5. The box 10 is divided by 5. The box 10 of the tissue carton 1 is formed by bending a carton blank 1a which is a paper base shown in FIGS. In the internal space of the tissue carton 1, tissue paper T, which is a laminated thin paper for household use, is housed so that the tissue paper T can be taken out from the take-out port 2a formed in the upper surface portion 2. It has become.

Here, the “box” has a shape in which an internal space in which the tissue paper T can be stored is formed, and examples thereof include a hexahedron shape such as a rectangular parallelepiped shape and a cubic shape. For example, FIG. 1 is an example in which the tissue carton 1 is configured in a rectangular parallelepiped shape.
In the tissue carton 1 shown in FIG. 1, the upper surface portion 2 and the bottom surface portion 3, the pair of side surface portions 4, 4 and the pair of wife surface portions 5, 5 are arranged in parallel so as to face each other. In addition, in these shapes, the chamfered portion of the ridge line portion of the two surfaces is also included in the “box”. The coated cardboard used for the box can generally have a basis weight of 300 to 450 g / m ² .
This tissue paper T can be manufactured by a known multi-stand type or rotary type inter-folder.
On the other hand, the tissue paper 2t constituting the tissue paper T has a ply structure in which two to three thin papers are laminated.
The raw pulp of the thin paper is a mixture of NBKP and LBKP, and may be appropriately combined with waste paper pulp. However, in terms of texture and the like, it is preferably composed only of NBKP and LBKP. In this case, the blending ratio is preferably NBKP: LBKP = 20: 80 to 80:20, and particularly preferably NBKP: LBKP = 30: 70 to 60:40.
The rice tsubo per thin paper constituting each ply of the tissue paper 2t according to the present invention is preferably 9 to 25 g / m ² , more preferably 10 to 15 g / m ² . If the rice tsubo is less than 9 g / m ² , it is preferable from the viewpoint of improving softness, but it is difficult to ensure adequate strength that can withstand use. On the other hand, when the rice tsubo exceeds 25 g / m ² , the entire paper becomes hard and a feeling of stickiness is generated, resulting in poor touch. In addition, the United States basis is based on the United States basis measurement method of JISP 8124 (1998).
On the other hand, the paper thickness of the tissue paper according to the present invention is desirably 100 to 160 μm, more preferably 120 to 140 μm in a two-ply state. If the paper thickness is less than 100 μm, it is preferable from the viewpoint of improving the softness, but it is difficult to ensure adequate strength as tissue paper. On the other hand, when the thickness exceeds 160 μm, the texture of the tissue paper is deteriorated and a feeling of roughness is generated during use.

As shown in FIG. 3, a resin film 6 having a slit 6 a is attached to the upper surface portion 2 so as to cover the outlet 2 a. The film 6 is adhered to the upper surface portion 2 by an adhesive 6b applied around the take-out port 2a on the back surface of the upper surface portion 2 so that the slit 6a faces the take-out port 2a. Then, the tissue paper T is taken out through the slit 6a. In addition, although the material of the film 6 employ | adopts polyethylene and a polypropylene, it is not limited to these. The take-out port 2a is formed by cutting a perforation provided in the upper surface portion 2 and cutting out a part of the upper surface portion 2.
The material of the film sheet according to the present invention is a sheet that requires separation from a paper box and is made of resin or resin. Specific examples include resinous film sheets made of resins such as polyethylene, polypropylene, and polyester, or laminated resinous film sheets obtained by laminating these, laminated film sheets obtained by laminating film sheets and paper, and synthetic paper made of resinous fibers. A sheet or the like. In consideration of take-out property, a resin film sheet is preferable, and a polyethylene film sheet is particularly preferable.
The thickness of the film sheet is preferably 15 to 200 μm. If it is less than 15 μm, the strength is insufficient, and the probability of tearing or breaking of the film sheet increases when the sanitary thin paper is taken out. On the other hand, when the thickness exceeds 200 μm, although there is no problem of strength such as tearing of the film sheet, the catch when the sanitary thin paper is taken out becomes large, and the thin paper may be difficult to take out or may be torn. In addition, the cost is high. When taking out property and holding property are considered, it is more preferably 25 to 60 μm.
As a method of measuring the film thickness used for the paper thickness, sheet material, and film layer, the specimen is sufficiently conditioned under the conditions of JIS P 8111 (1998), and then dial thickness gauge (thickness measuring instrument) under the same conditions. The paper thickness is measured in a 2-ply state using “PEACOCKG type” (manufactured by Ozaki Seisakusho), the film thickness is measured in a single layer state, and the sheet material is measured in the state of a sheet material. Specifically, confirm that there is no dust, dust, etc. between the plunger and the measuring table, lower the plunger on the measuring table, move the memory of the dial thickness gauge to adjust the zero point, and then Raise the plunger, place the sample on the test bench, slowly lower the plunger and read the gauge at that time. At this time, only the plunger is placed. The terminal of the plunger is made of metal and a circular plane having a diameter of 10 mm is perpendicular to the plane of the paper. The load at the time of measuring the thickness is about 70 gf at 120 μm. In addition, let the film thickness used for paper thickness, a sheet | seat material, and a film layer be an average value obtained by measuring 10 times.

  Moreover, as shown in FIG.2 and FIG.3, the upper-surface part 2, the bottom face part 3, and the side parts 4 and 4 are each formed in the substantially rectangular shape, and are connected so that bending is possible. And the long edge of the bottom face part 3 is connected to the longitudinal margin of the side face part 4 so that it can be bent at a folding line 3b. The carton blank 1a formed in this way bends the upper surface portion 2, the bottom surface portion 3 and the side surface portions 4 and 4, respectively, and bends the margin portion 3a to connect the bottom surface portion 3 to the side that is not connected. By gluing to the longitudinal end edge of the back surface of the side surface portion 4 and connecting the bottom surface portion 3 and the side surface portion 4, a cylindrical shape is formed.

  Further, an upper surface side flap 5b, a bottom surface side flap 5a, and a side surface side flap 5c are respectively extended from both side edges of the upper surface portion 2, the bottom surface portion 3, and the pair of side surface portions 4 and 4, and the bent portions F1 and F2 are respectively extended. , F3 are connected so as to be bent inward. Then, the top surface side flap 5b, the bottom surface side flap 5a, and the pair of side surface side flaps 5c are attached so as to overlap with each other, whereby the end face portion 5 as shown in FIGS. 1 and 4 is formed. .

  When the tissue carton 1 according to this embodiment is shipped from the factory, a plurality of stacked tissue papers T are stored in the internal space, and the flaps are pasted to form the end face portion 5 to seal the internal space. The strength of the side surface is increased, and the tissue paper T is prevented from escaping from the tissue carton 1 due to an external force when the tissue carton 1 is transported or displayed at the store.

Here, various dimensions of the tissue carton 1 according to the present embodiment will be described.
The ratio of the area of the tissue paper T to the area of the upper surface portion 2 of the box 10 (area ratio S1) is greater than 89.3% and 94.8% or less.
The reason why the area ratio S1 is made larger than 89.3% is to improve the difficulty of taking out due to the bias by reducing the bias of the tissue paper T in the box 10.
The reason why the area ratio S1 is set to 94.8% or less is a manufacturing reason. That is, in order to reduce the above-described bias, it is desirable to make the area ratio S1 as close as possible to 100%, but it is practically difficult, and if it exceeds 94.8%, the manufacturing efficiency is remarkably lowered. The upper limit was assumed.

The ratio of the length of the film 6 to the length of the box 10 in the longitudinal direction (length ratio L1) is 94.3% or more and 98.3% or less.
The reason why the length ratio L1 is 94.3% or more is that when the length ratio L1 is less than 94.3%, the area ratio S1 is 94.8%, that is, even under the most advantageous condition against the bias. This is because the property deteriorates (see Comparative Example 2 described later). At the end of the carton where pressure is applied to the upper surface, it is covered with a film, so that it can be taken out easily.
The length ratio L1 is set to 98.3% or less for manufacturing reasons. That is, as shown in the results of Table 1 to be described later, it is desirable to make the length ratio L1 as close as possible to 100%, but it is practically difficult, and if it exceeds 98.3%, the production efficiency is remarkably lowered. The value was the upper limit.

Next, a method for assembling the tissue carton 1 according to this embodiment will be described.
The carton blank 1a bends the upper surface portion 2, the bottom surface portion 3 and the side surface portions 4 and 4, respectively, and bends the adhesive margin portion 3a so as not to be connected to the bottom surface portion 3. A cylindrical internal space is formed by gluing the longitudinal end edge to connect the bottom surface portion 3 and the side surface portion 4. Thereby, the upper surface part 2, the bottom surface part 3, and the pair of side surface parts 4, 4 constitute the box 10.
Next, the plurality of stacked tissue papers T are stored in a cylindrical internal space.
Finally, the side flaps 5c are bent inward so that the end portions of the side flaps 5c arranged to face each other are opposed to each other, and then the bottom flaps 5a are bent to form the side flaps 5c. It sticks to the side surface side flap 5c by the adhesion part G1 provided in the outer surface side. Then, the upper surface side flap 5b is bent and attached to the bottom surface side flap 5a so that the back surface (inner surface) end portion of the upper surface side flap 5b overlaps with the outer surface end portion of the bottom surface side flap 5a. Here, adhesive portions G2 and G3 are provided at predetermined portions of the back surface end of the upper surface side flap 5b, and the upper surface side flap 5b is adhered to the bottom surface side flap 5a. In this way, by attaching the upper surface side flap 5b, the bottom surface side flap 5a, and the pair of side surface side flaps 5c so as to overlap each other, the end face portion 5 is formed and the internal space is sealed.

Here, Table 1 is a table showing the test results of the width and length of the film 6 and the take-out resistance value of the tissue paper T. Incidentally, as a method for measuring the take-out resistance value of the tissue paper T, it is performed in the following order.
(1) Push-pull gauge (IMADA CO., LTD. Model: Z2-20)
N) Fix the center tip of the tissue paper T to the tip of N).
(2) Take out the tissue paper T from the tissue carton 1 vertically at a constant speed of 0.4 to 0.6 seconds, and measure the maximum value of the removal resistance.
(3) By the method of (2) above, a total of 5 sets from the 1st set to the 5th set of the top layer, and 11
Take out a total of 5 sets of tissue paper T from 15 to 15.
(4) The measured values in the above (1) to (3) are averaged to obtain the takeout resistance value.

  As can be seen from Table 1, when the length of the film 6 is increased, the take-out resistance value is reduced and the take-out property of the tissue paper T is improved.

  Table 2 is a table showing the results of sensory evaluation of the ease of pulling out the sheets for Examples 1 to 5 of the tissue carton 1 according to this embodiment. Moreover, the comparative example 1 and the comparative example 2 equivalent to the Example and the conventional product for comparing a result are also shown collectively.

In Comparative Example 1 corresponding to the conventional product, the ratio of the area of the tissue paper T to the area of the upper surface portion 2 of the tissue carton 1 (area ratio S1) is “89.3%”. In Examples 1 to 5, the area ratio S1 is 94.8%. Therefore, compared with the comparative example 1, Examples 1-5 have the structure where the clearance gaps W3 and W3 with the inner wall of the tissue carton 1 are narrow, and the bias of the tissue paper T inside the tissue carton 1 is reduced. It has become.
On the other hand, in Comparative Example 2, as in Examples 1 to 5, the area ratio S1 is “94.8%”, and the bias of the tissue paper T inside the tissue carton 1 is reduced.

By the way, as a method of sensory evaluation of the ease of pulling out the sheet, 15 verifiers use all the tissue paper T by the method of “take out the tissue paper T from directly above at normal time (without bias of the tissue web)”. Evaluate the difficulty of taking out, tearing the tissue paper T, catching it, and taking it out.
Specifically, the number of torn tissue papers T is counted, and the difficulty of catching and taking out is evaluated by “◎: very good, ○: good, ×: bad”.

Similarly, 15 verifiers take out all the tissue paper T by the method of “take out the tissue paper T from directly above with the tissue web biased to one of the tissue cartons 1” Evaluate how hard it is torn, caught and removed.
Specifically, the number of torn tissue papers T is counted, and the difficulty of catching and taking out is evaluated by “◎: very good, ○: good, ×: bad”.
Finally, of the “normal time” and “biased state”, the worse evaluation is evaluated as a comprehensive evaluation, “：: very good, ○: good, ×: bad”.

Moreover, as a measuring method of web compressive force (g / cm < ² >), it carries out in the following order.

  As can be seen from Table 2, as in Examples 1 to 5, the area ratio S1 is “94.8%”, and the width in the longitudinal direction W2 of the film 6 is the width W1 in the longitudinal direction of the tissue carton 1. On the other hand, when it is “94.3% to 98.3%”, the comprehensive evaluation is “◎: very good” or “◯: good”, and the take-out property of the tissue paper T is improved. .

  On the other hand, in Comparative Example 1 corresponding to a conventional product, the vertical and horizontal widths of the plurality of stacked tissue papers T are “89” with respect to the vertical and horizontal widths of the tissue carton 1. .3% ”, the method of“ with the tissue web biased to either side of the tissue carton 1 and taking out the tissue paper T from directly above ”would cause the tissue paper T to break, and It is difficult to take out, and the overall evaluation is “x: bad”.

  In Comparative Example 2, the area ratio S1 is “94.8%”, which is the same as in Examples 1 to 5, but the length ratio L1 is “93.4%” and the lower limit value “94.3”. The tissue paper T is not torn, but the tissue paper T is caught at the slit end and the tissue carton 1 is lifted. Therefore, the overall evaluation is “x: bad”. .

  As described above, in the embodiment of the present invention, the gap between the tissue paper T and the inner wall of the tissue carton 1 is narrower than before by setting the area ratio S to be greater than 89.3% and 94.8% or less. Thus, the tissue paper T can be easily removed by reducing the unevenness of the tissue paper T in the tissue carton 1 and by setting the length L1 to 94.3% to 98.3%. .

  In the embodiment of the present invention, the film 6 has a constant thickness and a substantially rectangular shape. However, the thickness of both end portions in the longitudinal direction of the film 6 is increased, or both end portions in the longitudinal direction of the film 6 are short. You may increase the width in the hand direction. By increasing the thickness of both end portions of the film 6 in the longitudinal direction, the pressure between the back surface of the carton and the tissue paper can be lowered to facilitate removal. In addition, it is possible to further improve the take-out property by widening the width in the short direction of both end portions in the longitudinal direction of the film 6.

Here, FIG. 6 is an explanatory view showing an example of a film adhered to the back surface of the upper surface portion of the tissue carton. For example, in Fig.6 (a), the thickness of the longitudinal direction both ends E1 of the film 7 is made thicker than the center part C1. Moreover, in FIG.6 (b), the width | variety of the transversal direction of the longitudinal direction both ends E2 of the film 8 is made wider than the center part C2.
In this case, when the tissue paper T is taken out from the tissue carton 1, the take-out resistance is greatest at both ends in the longitudinal direction of the film, so that the thickness at both ends in the longitudinal direction of the film 7 is increased, or the length of the film 8 is increased. By widening the width in the short direction at both ends in the direction, friction at both ends in the longitudinal direction of the film 7 (or film 8) can be reduced, and the take-out property of the tissue paper T can be improved.
