The present invention relates to a seat storage box.

The sheet storage box has a structure in which a sheet such as tissue paper is stored in a box (also referred to as a carton) made of thick paper or the like and is pulled out from an outlet opening on the top surface of the box. Since the conventional sheet storage box is bulky when it is discarded as it is after use, it can be disassembled after use (see, for example, Japanese Patent No. 4142238).

Japanese Patent No. 4142238

An object of the present invention is to provide a seat storage box that places less burden on fingers during disassembly.

The sheet storage box according to the first aspect has a box body in which a plurality of sheets are removably stored and an opening for disassembling the box body, and the opening constitutes the box body. It is formed on at least one surface, and at least a part of the peripheral edge of the opening is corrugated. In the present specification, the box body is a container in which a sheet is housed. Removably accommodating the sheet means that the sheet can be taken out from the take-out port formed in the box body.

Further, the opening is inserted with a finger or a fingertip (hereinafter referred to as a finger or the like), and constitutes a trigger when the box body is disassembled after the seat storage box is used. The at least one surface indicates one or more of the plurality of surfaces constituting the box body. The perimeter of the opening corresponds to the edge of a portion of the surface on which the opening was formed. At least a part of the perimeter of the opening refers to all or part of the perimeter of the opening. The waveform shows a shape in which the concave and convex portions of the curve are repeatedly continuous.

In the first aspect, at least a part of the peripheral edge of the opening for disassembling the box is made into a waveform, so that the fingers and the like touching the portion formed in the waveform of the peripheral edge of the opening are curved to form the waveform. Contact only the convex part of. Therefore, when the box body is disassembled, it is possible to reduce the discomfort to the fingers and the like touching the peripheral edge of the opening. Further, even when the fingers or the like are pressed against the peripheral edge of the opening when the box body is disassembled, the burden on the fingers or the like can be reduced.

At least a part of the seat storage box according to the second aspect is curved. Curved means that at least a part of the periphery of the opening bends so as to be convex to the outside of the opening. In the second aspect, at least a part of the peripheral edge of the opening is curved so that the fingers and the like can smoothly touch the peripheral edge of the opening. Therefore, according to the second aspect, the discomfort to the fingers and the like touching the peripheral edge of the opening when the box body is disassembled is further reduced, and the burden on the fingers and the like is further reduced.

In the seat storage box according to the third aspect, a part other than the at least part of the peripheral edge of the opening is linear. The other part other than at least a part means all or a part of the peripheral edge of the opening except for at least a part formed in a corrugation.

In the third aspect, by making the other part of the peripheral edge of the opening linear, the fingers or the like inserted into the opening are likely to be caught on the part of the linearly formed peripheral edge. Therefore, in the third aspect, the dismantling work of the box body is easy.

The seat storage box according to the fourth aspect is configured by folding a part of the one surface of the other part. In the present specification, a part of one surface is folded back to mean that the other part of the peripheral edge of the opening is folded back by bending a part of the surface of the box body in which the opening is formed. It is shown that it corresponds to the part.

In the fourth aspect, the other part of the peripheral edge of the opening is formed by a portion where a part of the surface of the box is folded back, so that the finger or the like inserted into the opening is formed in a straight line. It can be stably hooked on the part. Therefore, according to the fourth aspect, the discomfort of the fingers and the like touching the peripheral edge of the opening is reduced, the burden on the fingers and the like is reduced, and the dismantling work of the box body becomes easier.

The other part of the seat storage box according to the fifth aspect is corrugated. In the fifth aspect, the other part formed linearly on the peripheral edge of the opening is made into a waveform, so that the fingers and the like touching the linearly formed portion on the peripheral edge of the opening form a waveform. Only the convex part of the curve can be touched. Therefore, when the box body is disassembled, it is possible to reduce the discomfort to the fingers and the like caught on a part of the peripheral edge of the opening. Further, even when a strong force is applied to a part of the peripheral edge where the fingers or the like are hooked at the time of disassembling the box body, the burden on the fingers or the like can be reduced.

In the sheet storage box according to the sixth aspect, the opening cut line is formed on the at least one surface when the opening is opened, and the cut of the opening cut line is the waveform.

The waveform constituting the cut of the cleavage line corresponds to the waveform constituting at least a part of the peripheral edge of the opening formed on the top surface after the cleavage line is cleaved.

In the sixth aspect, the cut of the cleavage line is a waveform, and the waveform constituting the cut of the cleavage line corresponds to the waveform constituting at least a part of the peripheral edge of the opening. Therefore, in the sixth aspect, by cleaving the cleavage line, an opening for disassembling the box can be formed on at least one surface constituting the box.

Further, in the sixth aspect, the cleavage line is cleaved to form an opening on at least one surface constituting the box body. Therefore, in the sixth aspect, it is difficult for dust to enter the inside of the box containing the sheet while the sheet storage box is in use (before the tear line for cleavage is cleaved).

In the seat storage box according to the seventh aspect, the at least one surface is a side surface of the box body. The side surface of the box body indicates a surface excluding the top surface and the bottom surface of the box body. In the seventh aspect, since the opening is formed on the side surface of the box body and the opening for dismantling the box body is not formed on the top surface, the opening for dismantling is provided at an inconspicuous position of the box body. be able to. Therefore, it is possible to prevent the box body from being accidentally disassembled when the seat storage box is used.

In the present specification, the base paper refers to a hard and thick paper that is a material for assembling a box body. The edge of the base paper exposed to the outside of the box refers to the edge of the base paper that appears on the exterior of the box when the box is assembled from the base paper.

In the tenth aspect, by making the edge of the base paper exposed to the outside of the box corrugated, even if a finger or the like touches the edge of the base paper exposed around the opening for dismantling when the box is disassembled, The burden on the fingers and the like can be reduced. Further, not only when the box body is disassembled, but also when the seat storage box is touched or grasped before or during use, the burden on the fingers and the like can be reduced.

In the seat storage box according to the eleventh aspect, the period of the waveform is 0.1 mm or more and 6 mm or less. As used herein, the period of the waveform refers to the distance between two adjacent protrusions or the distance between the concave portions of the waveform. When the period of the waveform is 0.1 mm or more and 6 mm or less, it indicates that the scale of the waveform is minute.

In the eleventh aspect, by setting the period of the waveform to 0.1 mm or more and 6 mm or less, the distance between the convex portions or the concave portions of the waveform is reduced. As a result, when the box body is disassembled, the discomfort of the fingers and the like touching the peripheral edge of the opening is further reduced, and the burden on the fingers and the like is further reduced.

Further, in the eleventh aspect, by reducing the distance between the convex portions or the concave portions on the peripheral edge of the opening, it is possible to suppress the deterioration of the appearance (or appearance) of the seat storage box due to the corrugated peripheral edge of the opening. ..

In the twelfth aspect, in the interlocking sheet storage box, the period of the waveform is twice or more the wave height of the waveform. As used herein, the wave height of the waveform indicates the vertical distance from the top of the convex portion of the waveform to the bottom of the concave portion.

In the twelfth aspect, by making the period of the waveform more than twice the wave height of the waveform, the inclination of the convex portion of the waveform formed on the peripheral edge of the opening becomes gentle, and the peripheral edge of the opening becomes smooth. Therefore, when the box body is disassembled, the discomfort of the fingers and the like touching the peripheral edge of the opening is further reduced, and the burden on the fingers or fingertips is further reduced.
