A convex cut line is formed on the upper surface side on the inside of the breaking cut line formed in the downward arc shape.

  According to the first aspect, on the upper surface side in the region inside the breaking cut line formed in the downward arc shape (the portion surrounded by the lower end portion of the upper surface side flap and the breaking cut line) By forming the convex cut line, the area inside the breaking cut line is easily deformed in the pressing direction of the finger. Therefore, when the area inside the breaking line is pressed with a finger to break the breaking line, it becomes easier to push the area inside the breaking line into the thin paper storage box with a smaller force. . Therefore, when disassembling the thin paper storage box, the area inside the breaking cut line can be easily pushed into the thin paper storage box, so that the upper surface side flap and the lower surface side flap can be easily separated.

  In the second aspect, the cut line is formed linearly or curvedly. By setting it as such a structure, it can be made the state which is easy to push in the area | region inside the cutting line for a fracture | rupture with a finger | toe.

  In the third aspect, the cut line is formed intermittently. By setting it as such a structure, it can be made into the state which is easy to push in the area | region inside the cutting line for a fracture | rupture similarly to the 2nd aspect.

  In the fourth aspect, an end portion of the cut line is formed at a distance from the breaking cut line. By setting it as such a structure, when breaking the cutting line for cutting, it can control that the cutting line breaks in conjunction with the break of the breaking line for breaking.

Note that the length in the width direction X and the width in the depth direction Y of the take-out port 16 can be appropriately determined based on the size of the tissue paper T and the like. Further, in the present embodiment, the take-out port 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. Other shapes may be used as long as they can be taken out smoothly.

  The thin paper storage box 10A has a lid 17 integrated with the thin paper storage box 10A on the upper surface 11 through a break line formed by a perforation at a stage before use. At the time of use, the lid portion 17 is cut along the breaking line for breaking, and the takeout port 16 is formed in the upper surface portion 11. Thereby, the tissue paper T in the accommodation space can be taken out from the takeout port 16. In the present embodiment, the breaking line for break means a line for cutting off the lid portion 17 during use.

  Further, a resin film 18 having a slit 18 a in the longitudinal direction is provided at the takeout port 16 of the upper surface portion 11 so as to cover the takeout 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. In addition, as a material of the resin-made film 18, polyethylene, a polypropylene, etc. can be used, However, It is not limited to these.

  The top 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 connected so as to be bendable. Then, as shown in FIG. 2, a trapezoidal margin part 12a for connecting to the longitudinal end edge of the side surface part 13 is connected to the longitudinal end edge of the bottom surface part 12 so that it can be bent at a folding line 12b. Yes.

  As shown in FIG. 2, the thin paper storage box 10 </ b> A includes an upper surface side flap 21 extending from both side edges of the upper surface part 11, a bottom surface side flap 22 extending from both side edges of the bottom surface part 12, and a pair of side surface parts. 13 has a pair of side surface side flaps 23 extending from both side edges. Each of the upper surface side flap 21, the bottom surface side flap 22, and the side surface side flap 23 is formed in a substantially rectangular shape, and is connected to the inside so as to be bent. The end face portion 14 is formed by an upper surface side flap 21, a bottom surface side flap 22, and a side surface side flap 23. Each flap of the upper surface side flap 21, the bottom surface side flap 22, and the side surface side flap 23 is bent inward. Then, the upper side of the bottom surface side flap 22 is bonded to the lower side of the top surface side flap 21 by an adhesive applied to the upper side of the bottom surface side flap 22. Further, both ends of the upper surface side flap 21 are bonded to a part of the upper side of the side surface side flap 23 and the bottom surface side flap 22 by an adhesive applied to both side surfaces of the upper surface side flap 21. Thereby, the end face part 14 is formed.

  The forming method of the thin paper storage box 10A is not particularly limited, and can be formed using a conventionally known forming method. An example of a method for forming the thin paper storage box 10A according to the present embodiment will be described. The top surface portion 11, the bottom surface portion 12, and the pair of side surface portions 13 shown in FIG. Further, the margin portion 12 a is bent and glued to the edge of the longitudinal end of the back surface of the side surface portion 13 that is not connected to the bottom surface portion 12 to connect the bottom surface portion 12 and the side surface portion 13. Thereby, the cylindrical box body in which the wife face part 14 is not formed is formed.

  Next, the side flaps 23 are folded inward so as to face the side flaps 23 arranged to face each other. Next, after the bottom surface side flap 22 is bent, the top surface side flap 21 is bent so that the end of the back surface (inner surface) of the top surface side flap 21 overlaps the outer surface end of the bottom surface side flap 22. Next, the upper surface side flap 21 is bonded to the bottom surface side flap 22 and the side surface side flap 23 by the adhesive portions G <b> 1 provided on both ends 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. By attaching the upper 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, the end face portion 14 is formed. Thereby, the thin paper storage box 10A shown in FIG. 1 is formed.

  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 line L1 for breakage is formed by perforations. In the present embodiment, a portion of the breaking cut line L1 that is formed in a downward arcuate shape is defined as an arcuate cut line L1-1 that extends from the arcuate cut line L1-1 toward the side surface 13 side. A portion extending in a straight line is defined as an extending cut line L1-2. The arcuate cut line L <b> 1-1 has a convex tip portion 25 that is formed in a convex shape toward the center of the bottom surface portion 12. The convex tip 25 becomes a starting point when breaking the breaking cut line L1, and at the time of disassembling the thin paper storage box 10A, by pressing the periphery of the convex tip 25 of the breaking cut line L1 with a finger, The arcuate cut line L <b> 1-1 is broken from the convex tip portion 25.

  In this embodiment, the bottom face side flap 22 has a convex cut line L2 on the upper surface part 11 side inside a breaking cut line L1 formed in an arc shape downward.

  By providing a cut line L2 inside the breaking cut line L1 of the bottom side flap 22, an inner region R of the breaking cut line L1 (the lower end portion 21a of the top side flap 21 and the breaking cut line L1) The portion surrounded by (2) is easily deformed in the direction in which the finger is pressed. Therefore, when the area R inside the breaking line L1 is pressed with a finger to break the breaking line L1, the area R inside the breaking line L1 is reduced with a smaller force than the thin paper storage box 10B. It becomes easy to push inside.

  Moreover, although the length of the cutting line L2 changes according to the magnitude | size of the area | region R inside the cutting line L1 for a fracture | rupture, it is preferable that it is 7-9 mm, for example.

  It is preferable to arrange the cut line L2 so as not to overlap the adhesive part G2. In the present embodiment, the score line L2 is formed in a convex shape and obliquely in the region R inside the fracture score line L1. Thereby, even if the position of the adhesive applied to the adhesive portion G2 of the overlapping portion between the upper surface side flap 21 and the bottom surface side flap 22 is shifted to the cutting line L2 side, the cutting line L2 is covered with the adhesive. Can be reduced. Therefore, since the area | region R inside the cutting line L1 for a fracture | rupture can maintain the state which is easy to deform | transform, the state which is easy to push in the part enclosed by the upper surface side flap 21 and the cutting line L1 for a fracture | rupture is maintained. Can do.

  Further, the cut line L2 is formed in the region R inside the breaking cut line L1 while being curved in a convex shape. Therefore, since the area formed by the breaking line L1 and the cutting line L2 substantially matches the surface of the finger to be pressed, the area R inside the breaking line L1 is easily pushed by the finger. be able to.

  Furthermore, the cut line L2 is formed intermittently. Therefore, the break due to the pushing of the finger can be started from the breaking cut line L1, so that the region R inside the breaking cut line L1 can be easily pushed with the finger.

  Moreover, the edge part of the cut line L2 is formed at intervals with the cut line L1 for a fracture | rupture. Thereby, when breaking the breaking line L1, the breaking line L2 can be prevented from breaking in conjunction with the breaking of the breaking line L1.

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

  A finger is pushed into a region R (a portion surrounded by the lower end portion 21a of the upper surface side flap 21 and the breaking cut line L1) inside the breaking cut line L1 formed in a downward arcuate shape, and FIG. As shown in FIG. 3, the breaking line L1 (arc-shaped cutting line L1-1) is broken to the lower end 21a of the upper surface side flap 21. Thereby, the area | region R inside the cutting line L1 for a fracture | rupture is cut | disconnected to the lower end part 21a of the upper surface side flap 21 along the circular arc-shaped cutting line L1-1.

  In the present embodiment, since the cut line L2 is formed in the region R inside the breaking cut line L1, the region R inside the breaking cut line L1 is easily deformed in the pressing direction of the finger. . Therefore, it becomes easier to push the region R inside the breaking line L1 into the inside of the thin paper storage box 10A with a smaller force.

  Then, the pushed-in finger is hooked on the inner surface of the upper surface side flap 21, and the upper surface side flap 21 is pulled up (drawn) outside the thin paper storage box 10A. On both end sides of the inner surface of the upper surface side flap 21, an adhesive portion G <b> 1 that is bonded to the bottom surface side flap 22 and the side surface side flap 23 is provided. Further, in the region R inside the breaking cut line L <b> 1 in the bottom surface side flap 22, a bonding portion G <b> 2 that is bonded to the top surface side flap 21 is provided at a position overlapping the lower portion of the top surface side flap 21. Therefore, when the upper surface side flap 21 is pulled up, the remaining breaking cut line L <b> 1 (extension cut line L <b> 1-2) is horizontal from the lower end portion 21 a of the upper surface side flap 21 to the side surface side of the bottom surface side flap 22. It is broken toward the end 22b. Thereby, the bottom face side flap 22 including the part (part of the adhesion part G2) adhere | attached with the upper surface side flap 21 is cut away. At this time, the adhesive portion G1 where the upper surface side flap 21 is bonded 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. Thereby, the upper surface side flap 21 and the bottom surface side flap 22 are cut | disconnected along the cut line L1 for a fracture | rupture, and the end face part 14 opens.

  After the upper surface side flap 21 and the bottom surface side flap 22 of one of the end face portions 14 are separated, the other end surface 14 also separates the upper surface side flap 21 and the bottom surface side flap 22 of the end surface portion 14 in the same manner as described above. Thereby, the thin paper storage box 10A can be formed into a cylindrical shape. Thereafter, the thin paper storage box 10A can be folded and discarded in a flattened state. In addition, you may cut | disconnect a pair of wife face part 14 into the upper surface side flap 21 and the bottom face side flap 22 simultaneously.

  Thus, according to the thin paper storage box 10A according to the present embodiment, when the thin paper storage box 10A is disassembled, the area R inside the breaking line L1 of the bottom side flap 22 can be pushed in with a small force. Thereby, since the burden which isolate | separates the upper surface side flap 21 and the bottom face side flap 22 can be reduced, 10 A of thin paper storage boxes can be disassembled more easily. Therefore, even a weak person such as an elderly person can easily dismantle the thin paper storage box 10A.

  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. 5, the cut line L2 is formed continuously. Also 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. 6, the cut line L2 is a straight line with a tapered tip. It may be formed in a shape.

<Second Embodiment>
A thin paper storage box according to a second embodiment of the present invention will be described with reference to the drawings. In addition, the same code | symbol is attached | subjected to the member which has the same function as the said embodiment, and detailed description is abbreviate | omitted. In the thin paper storage box according to the first embodiment, the thin paper storage box according to the present embodiment has a form in which the upper surface side flap of the end face portion is pulled up with a smaller force to break the breaking line. is there.

  FIG. 7 is a partial perspective view showing an example of a thin paper storage box according to the second embodiment of the present invention. As shown in FIG. 7, the thin paper storage box 10B according to the present embodiment is a breaking score line provided on the bottom side flap 22 of the thin paper storage box 10A according to the first embodiment of the present invention shown in FIG. L1 is formed so as to extend toward the upper surface portion 11 from the portion formed in the arc shape downward.

  In the present embodiment, a portion of the breaking cut line L1 that is formed in a downward arcuate shape is defined as an arcuate cut line L1-1, and is directed from the arcuate cut line L1-1 toward the upper surface portion 11 side. Then, the portion is extended to the end and the portion is designated as a drawing cut line L1-3. In the breaking line L1, the arcuate cutting line L1-1 and the extending cutting line L1-3 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 (on the upper surface portion 11 side).

  Since the breaking line L1 is formed as described above, when the thin paper storage box 10B is disassembled, when the upper surface side flap 21 is pulled up to separate the upper surface side flap 21 and the bottom surface side flap 22, the breaking notch The line L1 breaks in a direction close to the direction in which the upper surface side flap 21 is pulled up. 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 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 broken. Is easily separated along

  In the present embodiment, the extending cut lines L1-3 are formed to be curved upward and convex toward the upper surface portion 11 side. When pulling up the upper surface side flap 21, first, the direction in which the upper surface side flap 21 is pulled up is substantially the same and coincides with the direction of breakage of the breaking line L <b> 1. Therefore, of the force for pulling up the upper surface side flap 21, the force distributed to the breakage of the breaking line L <b> 1 can be reduced. Thereby, the force which pulls up the upper surface side flap 21 can be largely distributed by isolation | separation of the adhesion part G1 of the upper surface side flap 21 and the bottom face side flap 22. FIG.

  Further, the extending cut line L1-3 extends to the upper end portion 22a of the bottom surface side flap 22. The breaking direction of the breaking line L <b> 1 is substantially the same as the pulling direction of the upper surface side flap 21. Therefore, the force that pulls up the upper surface side flap 21 can be efficiently distributed to the breakage of the breaking line L1 until the breaking line L1 breaks up to the upper end portion 22a of the bottom surface side flap 22.

  In this embodiment, since the extending cut line L1-3 is formed in a curved shape so as to widen toward the upper surface portion 11, the extending cut line L1-3 is close to the direction in which the upper surface side flap 21 is pulled up. Breakage progresses in the direction. Therefore, the force of the finger for pulling up the upper surface side flap 21 when the upper surface side flap 21 and the bottom surface side flap 22 are separated can be efficiently distributed to the force that breaks the extended score line L1-3. Therefore, even if it does not apply big force when pulling up the upper surface side flap 21, the extending cut line L1-3 can be easily broken. Since the bottom surface side flap 22 is separated along the breaking line L1, the top surface side flap 21 and the bottom surface side flap 22 can be easily separated.

  Therefore, according to the thin paper storage box 10B according to the present embodiment, when disassembling the thin paper storage box 10B, first, the region R inside the breaking line L1 can be pushed in with a small force, and the upper surface of the end face 14 The side flaps 21 and the bottom side flaps 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 for breaking the breaking line L1 for breaking and separating the upper surface side flap 21 and the bottom surface side flap 22 are performed with a smaller force. Can do. 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 breaking 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 out. For example, the breaking line L1 for breakage may extend to the side surface side end portion 22b of the bottom surface side flap 22. That is, the breaking cut line L1 extends along the arcuate cut line L1-1 and the arcuate cut line L1-1 extending toward the side end 22b side of the bottom face side flap 22 toward the end. You may be comprised with the score line. Even in this case, when pulling up the upper surface side flap 21 when disassembling the thin paper storage box 10A, the upper surface of the end face 14 is broken as described above until the breakage of the breaking cut line L1 reaches a curved portion. The side flap 21 and the bottom side flap 22 can be easily separated with a small force. Moreover, in the location where the breaking line L1 for rupture is horizontal from the location where it is curved toward the end, the momentum of the rupture until then 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, the horizontal part can be broken with a small force.

  In the present embodiment, the cut line L2 is formed intermittently, but the present invention is not limited to this, and the cut line L2 may be formed continuously as shown in FIG. .

  In the present embodiment, the cut line L2 is formed to be curved, but the present invention is not limited to this, and as shown in FIG. 9, the cut line L2 is linear so that the tip is tapered. It may be formed.
