Description

A flat square box that can be repeatedly folded flat and restored

technical field

The invention belongs to the technical field of carton design and manufacture, and specifically relates to the design technology of a flat square box that can be repeatedly folded flat and restored.

Background technique

Cartons are used to hold items, but when the empty cartons are not filled with items, they still have the same large volume and occupy the same large space, which is not conducive to transportation and storage, resulting in increased transportation costs and reduced storage space.

Contents of the invention

The utility model provides a flat square box which can be folded and flattened repeatedly to reduce the space occupied by an empty paper box not filled with articles, and which can be restored to its original size without being damaged during use.

The technical scheme that the utility model takes:

The invention relates to a flat square box which can be repeatedly folded and restored, including the flat square box. The proposal is that the foldable flat square box with an opening is fastened on the bottom of a foldable box cover.

The positive effect after implementing the utility model is:

Because the empty flat square box can be folded flat, the volume is reduced, the space occupied by empty box transportation and storage is saved, and the cost is saved; and because of the ingenious structural design, it also brings joy to the user and achieves the effect of being willing to use.

Detailed ways

Now in conjunction with the accompanying drawings the utility model is further described

A flat square box that can be repeatedly folded and restored, including the flat square box, has the following structure: a foldable flat square box 1 with an opening is fastened to the bottom of a foldable box cover 2 .

The foldable flat square box is that on the inner side of the four bottom edges of the flat square box, there are notches 3 that can make the straight side bend down; one rectangular straight side and the opposite rectangular straight side, its two sides Angle takes flat square box height as right-angled side, makes isosceles right-angled triangle, and its hypotenuse 4 is notched on the inner side, becomes the fold that can be bent inwardly, has four isosceles right-angled triangles, and four hypotenuses inboards are notched to form fold.

The foldable box cover is a rectangular folded plate with four inboard notches equal in width to the square box; the width of the first and third fold lines 5 and 7 is the height of the flat square box; The width of four folding lines 6 and 8 is wide at the bottom of the flat square box.

The described fastening on the bottom of the foldable lid means that the flat square box is fastened between the first and second fold lines 5,6 at the bottom of the lid.
