DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a paper box,
The present invention relates to an easily disposable paper box that facilitates disposal of an empty box after use.

[0002]

2. Description of the Related Art Conventionally, when a paper box is discarded, the paper box is appropriately crushed or the paper box is unfolded by breaking the adhesive margin pasted with glue so that the dust is not bulky. And then discarded.

[0003]

However, the glue is firmly adhered to maintain the box's resistance, and the rigidity of the glue margin is strong. It was difficult to crush, and it was very difficult to destroy the glue allowance. Also, besides women and the elderly, especially when the paper box is large and the area for glue is large, or because of the structure of the paper box, there are several places for glue,
It took time and effort to destroy the glue margin that was firmly affixed.

The present invention has been made in view of the above-mentioned conventional problems, and has been devised and combined with a cutting line and a folding line so that a used paper box can be discarded without being bulky. An easily disposable paper box in which a paper box is easily crushed flat.

[0005]

SUMMARY OF THE INVENTION The present invention comprises a box-forming piece formed of a piece of paper and forming a hexahedral box, and opposes an upper lid piece which is an opening of the box-forming piece. This is an easily disposable paper box in which a cutting line is provided substantially on a diagonal line connecting two corners of a bottom surface to be cut, and a fold line toward the cutting line is provided on a line bisecting the angle of the other two corners.

Further, the present invention comprises a box-forming piece formed of one sheet of paper and forming a hexahedral box, and a bottom face facing an upper lid piece which is an opening of the box-forming piece.
A continuous crease line passing through the center of a crease line at a boundary between the bottom surface and the two side surfaces is provided over a pair of side surfaces connected to each other and facing each other on the bottom surface.
This is an easily disposable paper box in which a crease line that divides the angle into two equal parts is provided diagonally from the corner.
