  However, in the thin paper storage box that can be disassembled, there are adhesive portions between the flaps, and a strong force is required to peel off these adhesive portions during disassembly. In addition, since the opening for finger hook formed at the time of disassembly has a small opening size, a burden is imposed on the finger when forming the opening on the wife surface or when releasing the bonding of each flap. Therefore, in the conventional thin paper storage box, there are cases where it is difficult to disassemble the thin paper storage box.

  SUMMARY OF THE INVENTION It is an object of the present invention to provide a tissue paper storage box that can be easily disassembled.

  According to a first aspect of the present invention, there is provided an upper surface side flap having an upper surface provided with an outlet, a bottom surface, a pair of side surfaces, and a pair of wedges, and extending from a side edge of the upper surface. And a bottom flap extending from a side edge of the bottom portion, and a pair of side flaps extending from both side edges of the pair of side portions, respectively, and the wedge portion is disposed on the top surface side. The top side flap, the bottom side flap, and the pair of side flaps are each bent such that the bottom side flap overlaps the inside of the flap and the pair of side flaps overlap the inside of the bottom side flap. A joining portion formed by joining a lower end portion of the upper surface side flap and an upper end portion of the bottom surface side flap; and an end formed below the joining portion and near one side edge of the bottom surface side flap. From the department And a perforation that extends to the end of the side edge side of the square, to provide a tissue paper storage box.

  In the first aspect, a perforation extending between ends near both side edges of the bottom side flap is formed below a joining portion that joins the top side flap and the bottom side flap. In such a configuration, the bottom side flap is cut between both side edges by breaking a perforation extending between the ends near both side edges of the bottom side flap, and the top side flap and the cut bottom side flap are cut. Can be pulled out in a state in which a part of the part is joined. Thereby, even if the bonding portion exists in each flap, the bonding of each flap can be released with a small force.

  Further, in the first aspect, when the perforation is broken between the edges near both side edges of the bottom side flap, an opening is formed in the tissue paper storage box. Since the formed opening has a large opening size, a plurality of fingers or palms (hereinafter, palms and the like) can be inserted into such openings. Then, by pulling the wrist face outward with a palm or the like inserted into the opening, the adhesion of each flap is released, and the wife face of the thin paper storage box can be opened. Therefore, the burden on the finger can be reduced when the opening is formed in the wife surface or when the bonding of the flaps is released.

  Furthermore, in the first embodiment, the perforated surface of the thin paper storage box can be opened only by breaking the perforation and pulling out the upper flap and the bottom flap in a joined state. Therefore, the thin paper storage box can be easily disassembled by one operation (hereinafter, sometimes referred to as one action).

  A second aspect according to the present invention provides a tissue paper storage box, wherein the perforations extend from one side edge of the bottom side flap to the other side edge. In the second aspect, the perforations extend from one side edge of the bottom side flap to the other side edge, so that both ends of the perforation are continuous with both side edges of the bottom side flap. Thus, when the perforation is broken, the bottom flap is easily cut between both side edges. Therefore, a perforation extending from one side edge of the bottom side flap to the other side edge can break between both side edges of the bottom side flap with a small force.

  A third aspect according to the present invention provides a tissue paper storage box, wherein both end portions of the perforation are separated from both side edges of the bottom side flap. In the third aspect, one end of the perforation is separated from one side edge of the bottom side flap, and the other end of the perforation is separated from the other side edge of the bottom side flap. Therefore, both ends of the perforation are not continuous with both side edges of the bottom flap. In such a configuration, since the perforations do not extend from one side edge of the bottom side flap to the other side edge, the perforations may be formed before use or during use (hereinafter, sometimes referred to as disassembly). Breaking can be prevented.

  A fourth aspect according to the present invention provides a tissue paper storage box, wherein the perforations are curved in a direction away from the joint. In the fourth aspect, the perforation extending between the ends near both side edges of the bottom side flap is curved in a direction away from a joint portion joining the top side flap and the bottom side flap, thereby breaking the perforation. When doing this, the palm or the like is likely to be perforated. In addition, by bending the perforation in this manner, the opening formed after the perforation is broken can also be curved, so that it becomes easy to insert a palm or the like into the opening formed in the wrist surface during disassembly. .

  A fifth aspect according to the present invention provides a tissue paper storage box, wherein at least a part of the perforation is provided on the bottom side flap. In the fifth aspect, a part or all of the perforations extending between the ends near both side edges of the bottom side flap are provided on the bottom side flap of the wedge portion which is easily visible from the outside. Therefore, it is easy to confirm perforations at the time of disassembly.

  A sixth aspect according to the present invention provides a tissue paper storage box, wherein at least a part of the perforation is provided on the bottom portion. In the sixth aspect, part or all of the perforations extending between the ends near both side edges of the bottom side flap are provided on the bottom surface of the thin paper storage box that is hard to touch from the outside. Therefore, it is possible to prevent the perforation from being broken during use (before disassembly).

  In the sixth aspect, when a part of the perforation is provided on the bottom part, an opening is formed on the bottom part by first breaking a part of the perforation formed on the bottom part. be able to. Then, by inserting a plurality of fingers into the opening formed in the bottom surface, a palm or the like can be hung on the opening. In addition, when a palm or the like is placed on an opening formed by breaking a part of the perforation formed on the bottom surface, a fragment formed by breaking a part of the perforation is a side edge of the bottom surface. It bends inside the wife's face. When the bent fragment is pulled out with the top side flap and the bottom side flap joined together, it serves as a buffer for the palm or the like. Therefore, when releasing the adhesion of each flap, the burden on the palm or the like can be reduced.

  Furthermore, in the sixth aspect, as a configuration in which a part of the perforation is provided on the bottom surface, a configuration in which the entire perforation is provided on the bottom surface can be adopted. With such a configuration, the entire perforation can be provided on the bottom surface of the thin paper storage box that is difficult to touch from the outside. Therefore, it is possible to reliably prevent the perforation from being broken during use (before disassembly).

  A seventh aspect according to the present invention provides a tissue paper storage box, wherein a central portion of the perforation is provided on the bottom surface portion. In the seventh aspect, the central portion of the perforation that is easily broken in the perforation extending between the ends near both side edges of the bottom side flap is provided on the bottom surface of the thin paper storage box that is hard to touch from the outside. I have. Therefore, even when a portion other than the central portion of the perforation is provided on the wife surface portion, it is possible to prevent the perforation from being broken during use (before disassembly).

  Further, in the seventh aspect, since a part of the perforation formed on the bottom surface corresponds to the center of the perforation, the center of the perforation is broken, so that the bottom surface is closer to the wife surface. An opening can be formed so that a palm or the like can be inserted therein. Therefore, the top flap and the bottom flap can be easily pulled out while preventing the perforation from being broken during use (before disassembly).

  An eighth aspect according to the present invention provides a tissue paper storage box, wherein an arc portion in which a part of the perforation protrudes in an arc shape in a direction away from the joint portion is formed in a central portion of the perforation. I do. In the eighth aspect, a part of the perforation extending between the ends near both side edges of the bottom side flap forms an arc portion that protrudes in an arc shape from the center of the perforation. Since a part of the perforations constituting such an arc portion is more likely to be broken than other portions of the perforations which are not arc portions, the entire perforation can be broken by the break of the arc portion.

  In a ninth aspect according to the present invention, there is provided a tissue paper storage box, wherein the side flap has a cutout part in which a part of the bottom side is cut out. In the ninth aspect, since a part of the bottom surface side of the side flap is cut out by the notch, the perforation is broken when the top flap and the bottom flap are pulled out in a joined state. It becomes difficult for the formed fragments or the palms or the like inserted into the formed openings to be caught on each side flap. Thereby, the work of pulling out the upper surface side flap and the bottom surface side flap in a joined state is facilitated, and the adhesion of the upper surface side flap and the adhesion of the bottom surface flap to the pair of side surface side flaps can be surely released. .

  According to one embodiment of the present invention, a tissue paper storage box that can be easily disassembled can be provided.
