Therefore, in the first aspect, it is easy to dispose of the sheet storage box after use.

In the sheet storage box according to the second aspect, a mountain fold crease is formed at the base end of the notch flap. In the second aspect, by providing the fold line of the mountain fold at the base end of the notch flap, the notch flap is easily bent with the base end as the starting point. This makes it possible to prevent the notch flap from bending or bending at an unexpected portion when the notch flap is pushed into the seat storage box to form an opening for dismantling.

In the sheet storage box according to the third aspect, a cleavage line is formed on the bottom flap, and the notch flap is formed by cleavage of the cleavage line. In the present specification, the cut line for cleavage indicates a cut line in which cuts and ties (uncut portions between two cuts) are alternately arranged, and when the ties are broken, the cuts on both sides become continuous cuts.

In the third aspect, a cleavage line is formed on the bottom flap, and a notch flap is formed when the cleavage line is cleaved, whereby the sheet storage box is formed before dismantling (before and during use of the sheet storage box). ), It is difficult to form a dismantling opening on the wife surface unless the cleavage line is cleaved. Further, after using the sheet storage box, the sheet storage box can be disassembled by cleaving each cleavage line.

In the sheet storage box according to the fourth aspect, the cleavage line extends from the bottom edge side of the bottom surface side flap toward the end surface side end of the base end toward the bottom surface side end portion. In the fourth aspect, the cleavage line is easily cleaved by providing the cleavage line extending from the edge of the bottom flap on the top surface side toward the end of the base end on the bottom surface side. In addition, when the cleavage line is cleaved, it becomes easy to form a notch flap that can be inclined inside the side flap along the proximal end.

In the sheet storage box according to the fifth aspect, the cleavage line is from the top end of the bottom flap of the cleavage line from the top edge of the bottom flap. They are arranged at predetermined intervals. In the fifth aspect, the cleavage line is arranged at a predetermined distance from the top edge of the bottom flap of the bottom flap of the cleavage line. , It is possible to prevent unexpected opening of the opening cut line before disassembling the sheet storage box.

The sheet storage box according to the sixth aspect has an L-shaped opening cut line. In the sixth aspect, by making the shape of the cleavage line L-shaped, the cleavage direction of the cleavage line becomes two directions, so that the cleavage line is easily cleaved. In addition, the shape of the notch formed in the bottom flap after the cleavage line is cleaved becomes substantially rectangular. 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. In the seventh aspect, by curving the shape of the cleavage line, 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.

Further, in the seventh aspect, 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. In the eighth aspect, the linear shape of the cleavage line facilitates the positioning of the cleavage line with respect to the proximal end of the notch flap. Further, 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. In 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.

Further, in the ninth aspect, 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 according to the tenth aspect 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. In a tenth aspect, 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.

In the sheet storage box according to the eleventh aspect, 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. In the eleventh aspect, 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.
