Therefore, in the sixth aspect, the opening area for dismantling becomes wide, and it becomes easy to insert a finger into the opening for dismantling when dismantling the seat storage box.
  • the sheet storage box according to the seventh aspect has a curved shape in which the shape of the cleavage line is convex in the direction away from the base end.
  • the force for opening the cleavage line is easily transmitted along the cleavage line. Therefore, in the seventh aspect, the opening for dismantling can be formed with a small force.
  • the shape of the cleavage line is curved so as to be convex in the direction away from the proximal end, so that the notch formed in the bottom flap after the cleavage line is cleaved.
  • the shape of is approximately a fan shape. Therefore, in the seventh aspect, the opening area for dismantling becomes wide, and it becomes easy to insert a finger into the opening for dismantling when dismantling the seat storage box.
  • the sheet storage box according to the eighth aspect has a linear shape of the cut line for cleavage.
  • the linear shape of the cleavage line facilitates the positioning of the cleavage line with respect to the proximal end of the notch flap.
  • the shape of the notch formed in the bottom flap after the tear line is cleaved becomes substantially triangular. Therefore, in the eighth aspect, the opening area for dismantling becomes wide and the sheet storage box is dismantled. Sometimes a finger can be inserted into the dismantling opening.
  • the sheet storage box according to the ninth aspect has an inverted T-shape in the shape of the cut line for cleavage.
  • the ninth aspect by making the shape of the cleavage line into an inverted T shape, a maximum of two notch flaps can be formed when the cleavage line is opened. Thereby, only one of the two notch flaps is formed, and an opening for dismantling can be formed.
  • the opening area for dismantling can be increased by forming two notch flaps by making the shape of the cleavage line into an inverted T shape. Further, since it is possible to form two notch flaps having different rotation directions, the notch flaps can be pushed inside the seat storage box regardless of the dominant hand.
  • the sheet storage box has a pair of base ends in which the notch flap extends from the end edge on the top surface side of the bottom surface side flap to the bottom surface side.
  • the notch flap has a pair of proximal ends extending from the top-side edge of the bottom-side flap to the bottom-side, thereby having an inverted T-shaped cleavage line as described above.
  • the two notch flaps formed by cleavage of the can be inclined inward of the flank flaps along the proximal end, respectively. Therefore, both of the two notch flaps can be easily pushed inside the seat storage box.
  • the end edge on the bottom surface side of the portion of the top surface side flap that overlaps a part of the notch flap is curved toward the top surface side.
  • the opening area for dismantling can be widened to the top surface side by bending the end edge on the bottom surface side of the portion overlapping a part of the notch flap of the top surface side flap toward the top surface side. This makes it possible to reduce the burden on the finger when inserting the finger into the opening for dismantling or when the finger is hung on the flap on the top surface side.
  • the portion of the side flap that is joined to the top flap projects toward the top flap side.
  • the height of the side flap and the height of the bottom flap are set with respect to the top flap by projecting the portion of the side flap joined to the top flap toward the top flap side. Can be flush with each other.
  • the distance between the top side flap and the side surface side flap can be shortened, so that the amount of the adhesive required for joining the top surface side flap and the side surface side flap is small. can do.
  • the bond between the top flap and the side flap can be easily broken, so the sheet can be easily unbonded with less force.
  • the storage box can be disassembled.

Abstract

L'invention concerne une boîte de stockage de feuilles, qui comprend une face supérieure ayant une ouverture de sortie de feuilles, une face inférieure, une paire de faces latérales, et une paire de faces de pignon. La face de pignon comprend un rabat côté face supérieure s'étendant à partir d'un bord d'extrémité de la face supérieure, un rabat côté face inférieure s'étendant à partir d'un bord d'extrémité de la face inférieure, et une paire de rabats côté face latérale s'étendant à partir de bords d'extrémité des faces latérales respectives. Le rabat côté face supérieure est disposé sur les côtés externes du rabat côté face inférieure et des rabats côté face latérale. Le rabat côté face inférieure est disposé sur le côté externe des rabats côté face latérale. Le rabat côté face supérieure est collé au rabat côté face inférieure et aux rabats côté face latérale. Le rabat côté face inférieure n'est pas collé aux rabats côté face latérale. Une partie de découpe est formée sur le côté face supérieure du rabat côté face inférieure en découpant une partie du rabat côté face inférieure. La partie du rabat côté face inférieure correspondant à la partie de découpe constitue un rabat de découpe relié au rabat côté face inférieure. Le rabat de découpe comprend une extrémité de base s'étendant jusqu'à la face inférieure à partir d'un bord d'extrémité sur le côté face supérieure du rabat côté face inférieure. Le rabat de découpe est formé de façon à être inclinable sur le côté interne des rabats côté face latérale le long de l'extrémité de base. Le rabat côté face supérieure, dans un état d'agencement sur le côté externe du rabat côté face inférieure, chevauche une partie du rabat de découpe.
