Abstract

The utility model relates to a folding packaging box. The existing packing box has fixed volume and capacity and narrow application range. In order to solve the technical problem, the folding packing box is in a cube shape and is formed by folding a foldable sheet, the sheet can be made of paper, paperboard, thin plastic plates and the like, N horizontal creases are arranged on the front wall, the rear wall, the left wall and the right wall of the folding packing box, two sides of the left wall and the right wall are respectively provided with symmetrical zigzag creases, each zigzag crease is formed by sequentially connecting N +1 sections of oblique creases, the turning point of the zigzag crease is positioned on the horizontal crease, and N is a positive integer. By the design, when the folding packaging box is used, the capacity of the folding packaging box can be enlarged as long as the folding packaging box is stretched; on the contrary, the volume can be reduced by compressing the folding packing box, thereby meeting the requirements of different users. The utility model discloses folding packaging box has simple structure, volume advantage that can be big or small, adaptability is wide, is fit for acting as the packing carton of various products.

Description

folding box

Technical Fields

The utility model relates to a folding packaging box.

Background technique

The volume and capacity of the existing packaging box are fixed, and the scope of application is narrow.

Utility model content

The technical problem to be solved by the utility model is how to fill the above gap in the prior art and provide a foldable packaging box with variable volume and capacity.

In order to solve the above technical problems, the foldable packaging box is in the shape of a cube and is made of foldable sheets, which can be made of paper, cardboard and thin plastic boards. There are N horizontal creases on the top, among which there are symmetrical "zigzag" creases on both sides of the left and right walls, and each "zigzag" crease is connected by N+1 oblique creases in sequence. Its turning point is located on the horizontal crease, where N is a positive integer (N can be any positive integer, the larger the value, the better the folding and stretching effect of the folding packaging box). With such a design, when in use, the capacity of the folding packaging box can be enlarged as long as the folding packaging box is stretched; on the contrary, the volume of the folding packaging box can be reduced by compressing the folding packaging box to meet the needs of different users.

As an optimization, the folding packaging box is in the shape of a cuboid.

The folding packaging box of the utility model has the advantages of simple structure, large or small volume and wide adaptability, and is suitable as a packaging box for various products.
