Description

The present invention relates to a tissue paper storage box.

Tissue paper and other thin paper is stored in the internal space of the thin paper storage box, and the thin paper stored in the internal space of the thin paper storage box is taken out from the outlet provided on the upper surface of the thin paper storage box and used. Will be done.

Since the thin paper storage box is usually a rectangular parallelepiped paper box, if the thin paper storage box is discarded as it is after use, it becomes bulky. Therefore, it is desirable to disassemble the thin paper storage box and dispose of it in a flatly crushed state.

The pair of sides of the tissue paper storage box are generally formed by a top flap and a bottom flap. The bottom flap is provided with a notch line for breaking formed by perforations so that the thin paper storage box can be easily disassembled. When disassembling the tissue paper storage box, push your finger into the area inside the cutting line (the area between the upper flap and the cutting line) to break a part of the cutting line, and then break the part of the cutting line. Pull up the top flap to break the remaining rupture cut line. As a result, the bottom side flap bonded to the top surface side flap by gluing or the like is separated from the top surface side flap, and a pair of side surfaces of the thin paper storage box are opened. Then, the thin paper storage box is made into a cylindrical shape so that the thin paper storage box can be folded (see, for example, Patent Documents 1 and 2).

As a method of disassembling the thin paper storage box, for example, in Patent Document 1, the adhesive is locally attached to only one outer flap, and the inner flap and the outer flap are locally joined to determine the amount of the adhesive to be attached. Reduced tissue paper storage boxes have been proposed. In this tissue paper storage box, the adhesive that adheres the inner flap and the outer flap is easily peeled off when the thin paper storage box is disassembled, so that the thin paper storage box can be easily disassembled.

Further, Patent Document 2 proposes a method of disassembling the sanitary paper storage carton by breaking the dismantling cut line formed on one flap of the sanitary paper storage carton and then lifting the other flap to dismantle the sanitary paper storage carton. Has been done.

However, in the conventional technique, when separating the upper surface side flap and the bottom surface side flap constituting the side surface of the thin paper storage box, the direction in which the upper surface side flap is pulled up and the cutting line for breaking in order to separate the upper surface side flap from the bottom surface side flap. Is substantially orthogonal to the breaking direction of. Therefore, it may be difficult for the force to pull up the flap on the upper surface side to be transmitted to the cutting line for breaking.

In particular, in the case of a weak person such as an elderly person, it is not possible to exert a large force, so it may be difficult to disassemble the thin paper storage box.

One aspect of the present invention is to provide a thin paper storage box in which the upper surface side flap and the bottom surface side flap can be easily separated at the time of disassembly.

The thin paper storage box according to the first aspect of the present invention includes an upper surface portion having an outlet, a bottom surface portion, a pair of side surface portions, a pair of end face portions, an upper surface side flap extending from the side edge of the upper surface portion, and the above. The bottom surface side flap extending from the side edge of the bottom surface portion, and the bottom surface side flap having a cutting line for breaking formed in a downward arc shape, the top surface portion, the bottom surface portion, and a pair of side surface portions. And a pair of end faces are formed in a hexahedron shape, and the end faces are formed in a thin paper storage box formed by being bent so that the upper surface side flap and the bottom surface side flap are overlapped with each other, and the end surface portion is formed in an arc shape downward. The formed cutting cut line has a extending cutting line extending divergently toward the upper surface side from a portion formed in an arc shape downward.

According to the first aspect, when the thin paper storage box is disassembled, the inside of the breaking cut line formed in an arc shape downward (the portion surrounded by the lower end of the upper flap and the breaking cut line). The cutting line for breaking is broken from the convex tip portion formed in a convex shape toward the center of the bottom surface portion to the lower end portion of the upper surface side flap. After that, the pushed finger is hooked on the upper flap, and the upper flap is pulled up (pulled out) to the outside of the thin paper storage box. As a result, the remaining unbroken cutting cut line (a part of the extending cutting line) is broken from the lower end of the upper surface side flap toward the upper end side of the bottom surface side flap, so that the upper surface side flap is broken. The bottom flap including the portion adhered to is separated. Since the remaining rupture cut line (a part of the extension cut line) is formed so as to diverge toward the upper surface side, the rupture cut line breaks in a direction close to the direction in which the upper surface side flap is pulled up. Will progress. Therefore, the force of the finger for pulling up the top surface flap when separating the top surface side flap and the bottom surface side flap can be efficiently distributed to the force for breaking the breaking cut line, so that even if a large pulling force is not applied. , The cutting line for breaking can be easily broken. As a result, the bottom surface side flap can be easily separated along the breaking cut line, so that the top surface side flap and the bottom surface side flap can be easily separated. Therefore, the thin paper storage box can be disassembled more easily.

In the second aspect, the extension cut line is formed so as to be convexly curved upward toward the upper surface portion side. With such a configuration, when the upper surface side flap is pulled up, first, the pulling direction of the upper surface side flap and the breaking progress direction of the breaking cut line are substantially the same and coincide with each other. Therefore, among the forces for pulling up the upper surface side flap, the force distributed to the fracture of the fracture cutting line can be reduced. Therefore, the force for pulling up the upper surface side flap can be largely distributed by separating the adhesive portion between the upper surface side flap and the side surface side flap.

In the third aspect, the extension cut line extends to the upper end of the bottom flap. With such a configuration, the traveling direction of the breaking of the cutting cut line is substantially the same as the pulling direction of the upper surface flap. Therefore, the force for pulling up the flap on the upper surface side can be efficiently distributed to the breakage of the cut line for breakage.

In the fourth aspect, the extension cut line extends to the side end of the bottom flap. With such a configuration, the force for pulling up the upper surface side flap can be distributed to the breakage of the cutting cut line with almost no change in the bonding position between the upper surface side flap and the bottom surface side flap, which has been conventionally used. can.

In the thin paper storage box according to one aspect of the present invention, the upper surface side flap and the bottom surface side flap can be easily separated at the time of disassembly.

<First Embodiment>
The thin paper storage box according to the first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an example of a thin paper storage box according to the first embodiment of the present invention, and FIG. 2 is a developed view of the thin paper storage box according to the first embodiment of the present invention. FIG. 3 is a diagram showing a flap on the lower surface side when viewed from the end surface side of the thin paper storage box. As shown in FIGS. 1 to 3, the thin paper storage box 10A according to the present embodiment is a substantially rectangular parallelepiped (including a cube) including a top surface portion 11, a bottom surface portion 12, a pair of side surface portions 13, and a pair of end face portions 14. ) Shaped box. In the storage space in the thin paper storage box 10A, a large number of tissue papers T are stored in a laminated state.

The thin paper storage box 10A is formed by using coated cardboard or the like made from virgin pulp, used paper pulp or the like.

The external dimensions of the thin paper storage box 10A are determined by the amount and dimensions of the tissue paper T to be stored. For example, the length in the longitudinal direction (width) is about 100 to 250 mm, preferably about 200 to 250 mm. do. The length in the lateral direction (depth) is about 100 to 150 mm, preferably about 100 to 130 mm. The height is about 40 to 150 mm, preferably about 44 to 62 mm. Since the basis weight of the thin paper storage box 10A ensures sufficient strength to withstand use, when the thin paper storage box 10A is made of coated cardboard, the basis weight of the thin paper storage box 10A is 310-400 g. Approximately / m ² is preferable. The basis weight is measured according to the basis weight measuring method of JIS P 8124 (1998).

The thin paper storage box 10A has an outlet 16 on the upper surface portion 11. The take-out port 16 is a take-out port for taking out the tissue paper T housed in the storage space from the upper surface portion 11 side, and is formed in a substantially rectangular shape from the center of the upper surface portion 11 in the depth direction Y along the width direction X. Has been done. At the time of use, the tissue paper T housed in the storage space is taken out to the outside through the take-out port 16. The length of the take-out port 16 in the width direction X and the width in the depth direction Y can be appropriately determined based on the size of the tissue paper T and the like. Further, in the present embodiment, the outlet 16 is formed in a rectangular shape along the width direction X in the middle of the depth of the upper surface portion 11 of the thin paper storage box 10A, but the tissue paper T is not limited to this. Other shapes may be used as long as they can be taken out smoothly.

The thin paper storage box 10A has a lid portion 17 on the upper surface portion 11 which is integrated with the thin paper storage box 10A via a breaking cut line formed of perforations before use. At the time of use, the lid portion 17 is cut off along the breaking cut line, and the take-out port 16 is formed on the upper surface portion 11. As a result, the tissue paper T in the accommodation space can be taken out upward from the take-out port 16. In the present embodiment, the breaking cut line means a line that separates the lid portion 17 at the time of use.

Further, the take-out port 16 of the upper surface portion 11 is provided with a resin film 18 having a slit 18a in the longitudinal direction so as to cover the take-out port 16. The resin film 18 is fixed to the back surface of the upper surface portion 11 with an adhesive or the like applied around the take-out port 16. The tissue paper T is taken out through the slit 18a. The resin film 18 may be made of polyethylene, polypropylene, or the like, but is not limited thereto.

The upper surface portion 11, the bottom surface portion 12, and the pair of side surface portions 13 constituting the thin paper storage box 10A are each formed in a substantially rectangular shape, and are foldably connected to each other. Then, as shown in FIG. 2, a trapezoidal glue margin portion 12a for connecting to the longitudinal end edge of the side surface portion 13 is foldably connected to the longitudinal end edge of the bottom surface portion 12 by a bending line 12b. There is.

As shown in FIG. 2, the thin paper storage box 10A includes a top surface side flap 21 extending from both side edge edges of the top surface portion 11, a bottom surface side flap 22 extending from both side edge edges of the bottom surface portion 12, and a pair of side surface portions. It has a pair of side flaps 23 extending from both side edges of 13. The top surface side flap 21, the bottom surface side flap 22, and the side surface side flap 23 are each formed in a substantially rectangular shape, and are foldably connected inward. The end face portion 14 is formed by a top surface side flap 21, a bottom surface side flap 22, and a side surface side flap 23. The flaps of the top surface side flap 21, the bottom surface side flap 22, and the side surface side flap 23 are bent inward. Then, the upper side of the bottom surface side flap 22 is adhered to the lower side of the top surface side flap 21 by the adhesive applied to the upper side of the bottom surface side flap 22. Further, both ends of the upper surface side flap 21 are adhered to the side surface side flap 23 and a part of the upper surface side of the bottom surface side flap 22 by the adhesive applied to both side surfaces of the upper surface side flap 21. As a result, the end face portion 14 is formed.

The molding method of the thin paper storage box 10A is not particularly limited, and can be formed by using a conventionally known molding method or the like. An example of the molding method of the thin paper storage box 10A according to the present embodiment will be described. The upper surface portion 11, the bottom surface portion 12, and the pair of side surface portions 13 shown in FIG. 2 are bent. Further, the glue margin portion 12a is bent and glued to the edge of the longitudinal end of the back surface of the side surface portion 13 on the side that is not connected to the bottom surface portion 12 to connect the bottom surface portion 12 and the side surface portion 13. As a result, a tubular box body in which the end face portion 14 is not formed is formed.

Next, the side flaps 23 are bent inward so as to face the side flaps 23 that are arranged to face each other. Next, after bending the bottom surface side flap 22, the top surface side flap 21 is bent so that the end portion of the back surface (inner side surface) of the top surface side flap 21 overlaps the outer surface end portion of the bottom surface side flap 22. Next, the upper surface side flap 21 is adhered to the bottom surface side flap 22 and the side surface side flap 23 by the adhesive portions G1 provided on both end sides of the inner surface of the upper surface side flap 21. The upper surface side flap 21 is adhered to the bottom surface side flap 22 by the adhesive portion G2 provided at a predetermined portion of the outer surface end portion of the bottom surface side flap 22. The end face portion 14 is formed by mounting the top surface side flap 21, the bottom surface side flap 22, and the pair of side surface side flaps 23 so as to overlap each other. As a result, the thin paper storage box 10A shown in FIG. 1 is formed.

In the present embodiment, the bottom surface side flap 22 has a breaking cut line L1 (hereinafter, simply referred to as a breaking cut line L1) formed in an arc shape downward (bottom surface portion 12 side). The breaking cut line L1 is formed at a perforation. The breaking cut line L1 extends divergently toward the upper surface portion 11 side from a portion formed in an arc shape downward. As a result, when the upper surface side flap 21 is pulled up (pulled out) when the thin paper storage box 10A is disassembled and the upper surface side flap 21 and the bottom surface side flap 22 are separated, the breaking cut line L1 pulls up the upper surface side flap 21. The fracture proceeds in a direction close to the direction. Therefore, the force of the finger for pulling up the upper surface side flap 21 is efficiently distributed to the force for breaking the breaking cut line L1. Therefore, even if a large pulling force is not applied to the upper surface side flap 21, the breaking cut line L1 is easily broken, so that the upper surface side flap 21 and the bottom surface side flap 22 are separated from each other by the breaking cutting line L1. Easily separated along.

In the present embodiment, of the breaking cut line L1, the portion formed in an arc shape downward is referred to as an arc-shaped cut line L1-1, and the portion is directed from the arc-shaped cut line L1-1 toward the upper surface portion 11 side. It is extended to the end and the location is defined as the extension cut line L1-2. In the breaking cut line L1, the arcuate cut line L1-1 and the extension cut line L1-2 are connected at an inflection point P. In the present embodiment, the inflection point P is located above the lower end portion 21a of the upper surface side flap 21 (upper surface portion 11 side). The arc-shaped cut line L1-1 has a convex tip portion 25 formed in a convex shape toward the center of the bottom surface portion 12. The convex tip 25 serves as a starting point when breaking the breaking cut line L1, and when the thin paper storage box 10A is disassembled, the periphery of the convex tip 25 of the breaking cut line L1 is pressed with a finger. The arc-shaped cut line L1-1 is broken from the convex tip portion 25.

In the present embodiment, the extension cut line L1-2 is formed so as to be convexly curved upward toward the upper surface portion 11 side. When pulling up the upper surface side flap 21, first, the pulling direction of the upper surface side flap 21 and the breaking progress direction of the breaking cut line L1 are substantially the same and coincide with each other. Therefore, among the forces for pulling up the upper surface side flap 21, the force distributed to the fracture of the fracture cutting line L1 can be reduced. As a result, the force for pulling up the upper surface side flap 21 can be largely distributed by separating the adhesive portion G1 between the upper surface side flap 21 and the bottom surface side flap 22.

Further, the extension cut line L1-2 extends to the upper end portion 22a of the bottom surface side flap 22. The direction in which the breaking cut line L1 is broken is substantially the same as the pulling direction of the upper surface side flap 21. Therefore, the force for pulling up the upper surface side flap 21 can be efficiently distributed to the breakage of the breaking cut line L1 until the breaking of the breaking cutting line L1 reaches the upper end portion 22a of the bottom surface side flap 22.

In the present embodiment, the extension cut line L1-2 is formed in a curved shape in a divergent shape, but the present invention is not limited to this, and the extension cut line L1-2 may be formed in a straight line.

Next, a method of disassembling the thin paper storage box 10A after using the thin paper storage box 10A will be described.

For breaking, push your finger into the inner region R (the part surrounded by the lower end 21a of the upper surface side flap 21 and the breaking cutting line L1) formed in a downward arc shape. The cut line L1 (the arc-shaped cut line L1-1 and a part of the extended cut line L1-2) is cut to the lower end portion 21a of the upper surface side flap 21. As a result, the region R inside the breaking cut line L1 is separated to the lower end portion 21a of the upper surface side flap 21.

Then, as shown in FIG. 4, the pushed finger is hooked on the inner surface of the upper surface side flap 21 and the upper surface side flap 21 is pulled up to the outside of the thin paper storage box 10A. Adhesive portions G1 to be bonded to the bottom surface side flap 22 and the side surface side flap 23 are provided on both end sides of the inner surface of the top surface side flap 21. Further, in the region R inside the breaking cut line L1 in the bottom surface side flap 22, an adhesive portion G2 to be adhered to the top surface side flap 21 is provided at a position overlapping the lower part of the top surface side flap 21. Therefore, when the upper surface side flap 21 is pulled up, the remaining unbroken cutting cut line L1 (remaining of the extending cutting line L1-2) is changed from the lower end portion 21a of the upper surface side flap 21 to the upper end portion of the bottom surface side flap 22. It is broken toward the 22a side. As a result, the bottom surface side flap 22 including the portion bonded to the top surface side flap 21 (the portion of the adhesive portion G2) is separated. Further, at this time, the adhesive portion G1 in which the upper surface side flap 21 is adhered to the bottom surface side flap 22 and the side surface side flap 23 is also peeled off, and the upper surface side flap 21 and the bottom surface side flap 22 are separated from each other. As a result, the upper surface side flap 21 and the bottom surface side flap 22 are separated from each other along the breaking cut line L1, and the end face portion 14 is opened.

In the present embodiment, the extension cut line L1-2 is formed in a curved shape that spreads toward the upper surface portion 11 side, so that the extension cut line L1-2 is close to the direction in which the upper surface side flap 21 is pulled up. Fracture progresses in the direction. Therefore, the force of the finger for pulling up the upper surface side flap 21 when separating the upper surface side flap 21 and the bottom surface side flap 22 can be efficiently distributed to the force for breaking the extension cut line L1-2. Therefore, the extension cut line L1-2 can be easily broken without applying a large force when pulling up the upper surface side flap 21. Since the bottom surface side flap 22 is separated along the breaking cut line L1, the top surface side flap 21 and the bottom surface side flap 22 can be easily separated.

After separating the upper surface side flap 21 and the bottom surface side flap 22 of one end face portion 14, the other end surface portion 14 also separates the upper surface side flap 21 and the bottom surface side flap 22 of the end face portion 14 in the same manner as described above. As a result, the thin paper storage box 10A can be made into a cylindrical shape. After that, by folding the thin paper storage box 10A, it can be disposed of in a flatly crushed state. The pair of end face portions 14 may be separated into the upper surface side flap 21 and the bottom surface side flap 22 at the same time.

As described above, according to the thin paper storage box 10A according to the present embodiment, when the thin paper storage box 10A is disassembled, the upper surface side flap 21 and the bottom surface side flap 22 of the end face portion 14 can be easily separated with a small force. The thin paper storage box 10A can be disassembled more easily. Therefore, even a weak person such as an elderly person can easily disassemble the thin paper storage box 10A.

In the present embodiment, the breaking cut line L1 is formed so as to extend to the upper end portion 22a of the bottom surface side flap 22, but is not particularly limited as long as the top surface side flap 21 can be easily pulled up. For example, as shown in FIG. 5, the breaking cut line L1 may extend to the side end portion 22b of the bottom surface side flap 22. That is, the breaking cut line L1 extends from the arc-shaped cut line L1-1 and the arc-shaped cut line L1-1 toward the side end portion 22b side of the bottom surface side flap 22. It may be composed of the cut line L1-3. Even in this case, when the upper surface side flap 21 is pulled up at the time of disassembling the thin paper storage box 10A, the breakage of the extension cut line L1-3 is as described above, until the end-spreading curved portion of the end face portion 14. The top surface side flap 21 and the bottom surface side flap 22 can be easily separated with a small force. Further, in the place where the extension cut line L1-3 is horizontal from the part where it is curved toward the end, the momentum of the breakage up to that point is used. As a result, the bottom surface side flap 22 including the portion bonded to the top surface side flap 21 (the portion of the adhesive portion G2) is lifted upward (or forward) together with the top surface side flap 21. Therefore, even a horizontal portion can be broken with a small force.

<Second embodiment>
The thin paper storage box according to the second embodiment of the present invention will be described with reference to the drawings. Members having the same functions as those in the above embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. The thin paper storage box according to the present embodiment is the region inside the breaking cut line (the portion surrounded by the lower end of the upper flap and the breaking cut line) in the thin paper storage box according to the first embodiment. Is added with a form in which the cutting line for breaking is broken by pushing in with a smaller force.

FIG. 6 is a perspective view showing an example of a thin paper storage box according to a second embodiment of the present invention. As shown in FIG. 6, the thin paper storage box 10B according to the present embodiment has a convex shape on the bottom surface side flap 22 of the thin paper storage box 10A according to the first embodiment of the present invention shown in FIG. The notch line L2 is provided. The cut line L2 is provided in a region R inside the breaking cut line L1 (a portion surrounded by the lower end portion 21a of the upper surface side flap 21 and the breaking cutting line L1).

By providing the cut line L2 in the inner region R of the breaking cut line L1 of the bottom surface side flap 22, the inner region R of the breaking cut line L1 is easily deformed in the finger pressing direction. Therefore, when the area R inside the cutting line L1 is pressed with a finger to break the cutting line L1, the area R inside the cutting line L1 is pressed with a smaller force to the thin paper storage box 10B. It becomes easier to push it inside.

It is preferable that the cut line L2 is arranged so as not to overlap with the adhesive portion G2. In the present embodiment, the cut line L2 is formed diagonally in a convex shape in the region R inside the cut line L1 for breaking. As a result, even if the position of the adhesive applied to the overlapping portion between the top surface side flap 21 and the bottom surface side flap 22 shifts to the notch line L2 side, it is possible to reduce that the notch line L2 is covered with the adhesive. can.

Further, the end portion of the cut line L2 is formed at a distance from the cut cut line L1 for breaking. As a result, when the breaking cut line L1 is broken, it is possible to prevent the cutting line L2 from breaking in conjunction with the breaking of the breaking cut line L1.

Therefore, according to the thin paper storage box 10B according to the present embodiment, when the thin paper storage box 10B is disassembled, the region R inside the breaking cut line L1 can be pushed in with a small force, and the upper surface of the end face portion 14 is formed. The side flap 21 and the bottom side flap 22 can be separated with a small force. As described above, in the thin paper storage box 10B according to the present embodiment, a series of operations of breaking the breaking cut line L1 and subsequently separating the top surface side flap 21 and the bottom surface side flap 22 are performed with a smaller force. Can be done. Therefore, the thin paper storage box 10B according to the present embodiment can more easily disassemble the thin paper storage box 10B.

In the present embodiment, the cut line L2 is formed intermittently, but the present invention is not limited to this. For example, as shown in FIG. 7, the cut line L2 is continuously formed. May be good.

In the present embodiment, the cut line L2 is formed to be curved, but the present invention is not limited to this. For example, as shown in FIG. 8, the cut line L2 is a straight line so that the tip is tapered. It may be formed in a shape.

<Third embodiment>
The thin paper storage box according to the third embodiment of the present invention will be described with reference to the drawings. Members having the same functions as those in the above embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. The thin paper storage box according to the present embodiment is the thin paper storage box according to the first embodiment, in which the lower end of the flap on the upper surface side is easily fitted to a finger and the cutting line for breaking is broken. Is.

FIG. 9 is a perspective view showing an example of a thin paper storage box according to a third embodiment of the present invention. As shown in FIG. 9, the thin paper storage box 10C according to the present embodiment is formed in an upward arc shape on the upper surface side flap 21 of the thin paper storage box 10A according to the first embodiment of the present invention shown in FIG. It has a notch 31. The cutout portion 31 is provided at a position corresponding to the arc-shaped position (arc-shaped cut line L1-1) of the breaking cut line L1.

Since the notch portion 31 is formed in an arc shape, it easily fits the shape of the finger. Therefore, when the finger is pushed into the region R inside the breaking cut line L1 of the bottom surface side flap 22 (the portion surrounded by the lower end portion 21a of the upper surface side flap 21 and the breaking cut line L1), the upper surface side is pushed into the finger. The lower end 21a of the flap 21 is difficult to bite. Further, even when the upper surface side flap 21 is pulled up to the outside of the thin paper storage box 10A to separate the upper surface side flap 21 and the bottom surface side flap 22, it is difficult for the lower end portion 21a of the upper surface side flap 21 to bite into the finger. Therefore, it is possible to make it difficult to feel a burden (pain in some cases) on the finger. That is, since it is gentle on the finger, the breaking cut line L1 is easily broken.

Further, by forming the notch portion 31 in the upper surface side flap 21, the region R inside the breaking cut line L1 can be formed on the upper surface portion 11 side from the lower end portion 21a of the upper surface side flap 21. Therefore, even if the height of the thin paper storage box 10C is lowered, it is necessary to maintain a state in which the region R inside the breaking cut line L1 can be easily pushed in and a state in which the top surface side flap 21 and the bottom surface side flap 22 can be easily separated. Can be done.

The ratio (h / w) of the maximum height h to the maximum width w of the cutout portion 31 is preferably 0.03 to 0.60. If h / w is within this range, the finger is cut when pushing the finger into the inner region R of the cutting cut line L1 and when separating the upper surface side flap 21 and the bottom surface side flap 22 of the end face portion 14.

In the above embodiments, the tissue paper has been used as the thin paper, but the present invention is not limited to this, and other thin paper such as paper towels, kitchen paper, and cleaning wipes can also be used.

The size of the tissue paper T accommodated in the accommodation space is, for example, a shape of the upper surface and a bottom surface of about 60 to 130 mm × 150 to 250 mm and a height of about 20 to 110 mm. The number of plies of the tissue paper is 2 plies, and the basis weight per ply is 9.0 to 25.0 g / m ² , more preferably 10.0 to 15.0 g / m ² . The paper thickness is 100 to 160 μm for two plies, and more preferably 120 to 140 μm. The basis weight means a value measured based on JIS P 8124 (1998). As a method for measuring the paper thickness, for example, after the test piece is sufficiently humidity-controlled under the conditions of JIS P 8111 (1998), the dial thickness gauge (thickness measuring instrument) "PEACOCK G type" (Ozaki Seisakusho) is used under the same conditions. (Manufactured), measure in a 2-ply state. Specifically, make sure that there is no dust or dust between the plunger and the measuring table, and then install the plunger on the measuring table. After that, the memory of the dial thickness gauge is moved to match the zero point. Then, raise the plunger, place the sample on the test table, 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 so that a circular plane having a diameter of about 10 mm hits the paper plane perpendicularly. The load at the time of measuring the paper thickness is about 70 gf. The paper thickness is an average value obtained by performing the measurement 10 times.

Although the embodiments have been described above, each of the above embodiments is presented as an example, and the present invention is not limited to each of the above embodiments. Each of the above embodiments can be implemented in various other forms, and various combinations, omissions, replacements, changes, etc. can be made without departing from the gist of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are also included in the scope of the invention described in the claims and the equivalent scope thereof.

Hereinafter, embodiments will be described in more detail with reference to Examples and Comparative Examples, but the embodiments are not limited to these Examples.

<Example 1: Examination of tensile strength of upper surface side flap 21>
[Example 1-1]
A thin paper storage box (base paper having a basis weight of 310 g / m ² , back juniper coated cardboard, height 44 mm, width 229 mm, depth 110 mm) according to the first embodiment shown in FIG. 1 was prepared. Then, a finger was pushed into the region R inside the breaking cut line L1 of the end face portion 14, and a part of the breaking cut line L1 was broken. Then, the region R inside the breaking cut line L1 was folded back to the back surface of the upper surface side flap 21. Then, a double clip (narrow mouth width 13 mm, depth 7 mm) was sandwiched and fixed at the fold of the folded upper surface side flap 21. Then, attach it to the digital force gauge (Z2-20N, manufactured by IMADA) so that the key-shaped tip of the key-shaped standard attachment A-1 (width 12 mm, small hook) faces the display surface of the measured value, and attach it to the double clip. Of the two picked parts, it was hooked on the picked part located on the outside of the box. After that, the thin paper storage box is stored so that the other bottom side flap 22 and the side surface portion 13 of the thin paper storage box are in contact with the horizontal and flat table while being pressed so that the upper surface side flap 21 faces upward. The box was installed and fixed. Here, the fixed state in the measurement of the tensile strength means that two places on the bottom side flap 22 located 20 mm in both the depth direction from the inner region R of the breaking cut line L1 are pressed by the fingers of the hand. , The other end face portion 14 is to be kept at the time of measurement even at the time of measurement from a horizontal and flat table. Next, the digital force gauge was pulled at once from the fixed state in parallel with the direction of about 45 ° upward from the upper surface portion 11 side with respect to the upper surface side flap 21 of the thin paper storage box. Here, "at once" in the measurement of tensile strength refers to a tensile method in which the time required from the start to the end of tension is 1 second. Then, the tensile strength (kgf) of the digital force gauge at the time when the remaining portion of the breaking cut line L1 was broken and the top surface side flap 21 and the bottom surface side flap 22 were separated was measured. The measurement was performed 7 times, and the value of the tensile strength for 7 times and the average value thereof were obtained.

[Example 1-2]
Except that the thin paper storage box according to the first embodiment shown in FIG. 1 was changed to a thin paper storage box having a bottom side flap 22 provided with a notch line for breaking shown in FIG. 5, the same as in Example 1-1. It was done in the same way.

[Comparative Example 1]
Except that the thin paper storage box according to the first embodiment shown in FIG. 1 was changed to a thin paper storage box having a bottom side flap 22 provided with a notch line for breaking shown in FIG. 13, the same as in Example 1-1. It was done in the same way.

Table 1 shows the values of the tensile strengths of each of the examples and the comparative examples for 7 times, and the average values thereof.

In each of the thin paper storage boxes of Examples 1-1 and 1-2, it was confirmed that the average value of the tensile strength of the upper surface side flap 21 was about 0.94 or less. On the other hand, in the thin paper storage box of Comparative Example 1, it was confirmed that the average value of the tensile strength of the upper surface side flap 21 was about 1.2 or more. Therefore, the breaking cut line L1 is formed so as to extend from the portion formed in the shape of an arc downward to the upper end portion 22a of the bottom flap 22 so as to be curved upward in a convex shape and spread toward the end. Therefore, the tensile strength of the upper surface side flap 21 can be reduced. Therefore, when the thin paper storage box is disassembled, the upper surface side flap 21 and the bottom surface side flap 22 of the end face portion 14 can be easily separated with a small force. Therefore, it can be said that if the thin paper storage box according to the present embodiment is used, the thin paper storage box can be easily disassembled without applying a large force.

<Example 2: Examination of ease of pushing the convex tip of the cutting line for breaking>
[Example 2-1]
A thin paper storage box (base paper having a basis weight of 310 g / m ² , back juniper coated cardboard, height 44 mm, width 229 mm, depth 110 mm) according to the second embodiment shown in FIG. 6 was prepared. Then, the thin paper storage box was installed so that the other end surface portion 14 of the thin paper storage box was in contact with the horizontal and flat table so that the end face portion 14 was facing upward, and the thin paper storage box was fixed. Here, the fixed state in the measurement of the indentation strength means that both ends in the depth direction on the end face portion 14 so as to face upward are pressed by the fingers of the hand, and the other end face portion 14 is horizontal and flat during the measurement. Do not leave the table even when measuring. Then, the key-shaped tip of the key-shaped standard attachment A-1 (width 12 mm, small hook) was attached to the digital force gauge in parallel with the display surface of the measured value. Then, with the thin paper storage box fixed, the most advanced part (the part farthest from the digital force gauge) of this key-shaped standard attachment A-1 is the bottom flap 22 of the end face portion 14 and the notch line for breaking. It was applied to a position 2 mm inside the convex tip portion 25 of L1. Then, I pushed it downward at once with a digital force gauge. Here, "at once" in the measurement of the pushing strength refers to a pushing method in which the time required from the start to the end of pushing is 0.5 seconds. The indentation strength of the digital force gauge at the time when the break line L1 was broken was measured. The measurement was performed 7 times, and the value of the indentation strength for 7 times and the average value thereof were obtained.

[Example 2-2]
Except for changing the thin paper storage box according to the second embodiment shown in FIG. 6 to a thin paper storage box having a bottom side flap 22 having a cutting line L1 and a cutting line L2 shown in FIG. The procedure was the same as in Example 2-1.

[Example 2-3]
Similar to Example 2-1 except that the thin paper storage box according to the second embodiment shown in FIG. 6 is changed to a thin paper storage box provided with the cutting line L1 and the cutting line L2 shown in FIG. I went there.

[Comparative Example 2-1]
The procedure was carried out in the same manner as in Example 2-1 except that the thin paper storage box according to the second embodiment shown in FIG. 6 was changed to the thin paper storage box according to the first embodiment shown in FIG.

[Comparative Example 2-2]
Except that the thin paper storage box according to the second embodiment shown in FIG. 6 was changed to a thin paper storage box having a bottom side flap 22 having a cutting line L1 and a cutting line L2 shown in FIG. The procedure was the same as in Example 2-1.

Table 2 shows the values of the indentation strengths for each of the examples and the comparative examples for seven times, and the average values thereof.

In each of the thin paper storage boxes of Examples 2-1 to 2-3, it was confirmed that the average value of the pushing strength of the upper surface side flap 21 was 0.58 or less. On the other hand, in the thin paper storage boxes of Comparative Examples 2-1 and 2-2, it was confirmed that the tensile strength of the upper surface side flap 21 was 0.68 or more. Therefore, in addition to the cutting line L1 for breaking, by forming the cutting line L2 inside the cutting line L1 while bending upward in a convex shape, the inside of the cutting line L1 for breaking is formed at the time of dismantling. The region R can be easily pushed in. Therefore, if the thin paper storage box according to the present embodiment is used, the region R inside the breaking cut line L1 can be pushed in with a smaller force, so that the thin paper storage box can be disassembled without applying a large force. It can be said that this can be done more easily.
