Description

Technical Field

[0001] This utility model relates to the field of food paper box technology, specifically a foldable portable food paper box. Background Technology

[0002] Most existing disposable food cartons are fixed three-dimensional structures (such as boat-shaped boxes and square boxes), which take up a lot of space during transportation and storage, increasing logistics costs.

[0003] A small number of foldable cardboard boxes usually rely on glue or complex folding steps. After folding, they are easy to loosen and not easy to fix, or after unfolding, the structure is unstable and easily deformed. Utility Model Content

[0004] The purpose of this invention is to provide a foldable and portable food box to solve the problems mentioned in the background art.

[0005] The technical solution of this utility model is: a foldable portable food paper box, including a paper box body. Two foldable sealing plates and bending plates are extended from the openings at both ends of the paper box body. Two triangularly arranged outward folding seams are provided on the bending plates. The bending plates are folded outward through the outward folding seams to form a triangular part. The side wall of the paper box body is provided with a side hole corresponding to the triangular part. The conical tip of the triangular part extends into the side hole to form a locking fit.

[0006] The aforementioned components achieve the following effects: Foldable sealing plates and bending plates extend from the openings at both ends of the cardboard box body. The bending plate folds outward using its triangularly shaped outer fold seam to form a triangular portion. The conical tip of the triangular portion extends into the side hole in the side wall of the cardboard box body to form a locking fit. This achieves the goal of fixing the folded state without glue, solving the problem of existing foldable cardboard boxes relying on glue for bonding or easily loosening after folding. It increases the structural stability after folding, and the foldable design reduces space occupation during transportation and storage, thus lowering logistics costs.

[0007] Preferably, the main body of the cardboard box includes two long side panels and two short side panels, and a folded edge is provided at the connection between the long side panels and the short side panels.

[0008] The aforementioned components achieve the following effect: By incorporating folded edges at the joints of the two long and two short side panels of the cardboard box body, these edges provide guidance and support for the folding of the long and short side panels. The presence of these edges allows the long and short side panels to fold along a fixed trajectory, forming a stable three-dimensional structure after unfolding. This simplifies the folding process, solves the problem of complex folding steps in existing foldable cardboard boxes, improves the ease of unfolding and folding the box, and enhances the structural stability after unfolding.

[0009] Preferably, one side of one of the short side plates is provided with an adhesive edge, and the outer side of the adhesive edge is bonded to the inner side of the adjacent long side plate.

[0010] The aforementioned components achieve the following effect: by setting an adhesive edge on one side of one of the short side panels, and bonding the outer side of the adhesive edge to the inner side of the adjacent long side panel, the adhesive edge fixes the short side panel and the long side panel together to form the basic framework of the cardboard box. The working principle is to replace overall bonding with partial bonding, reducing glue usage while ensuring structural stability. This simplifies the assembly process, solves the problem of existing cardboard boxes relying on large amounts of glue or having complex assembly, improves production efficiency, and reduces dependence on glue.

[0011] Preferably, the side hole away from the port of the main body of the paper box is arc-shaped.

[0012] The aforementioned components achieve the following effects: the arc-shaped structure reduces frictional resistance and stress concentration between the triangular part and the side hole. This facilitates quick locking and unlocking of the triangular part and the side hole, resolving potential issues of folding operation jamming or structural damage caused by sharp edges of the side hole, and improving the smoothness of folding operations and the lifespan of the cardboard box.

[0013] This utility model provides a foldable portable food box with the following improvements and advantages compared with the prior art:

[0014] This utility model features a foldable sealing plate and a bending plate extending from the openings at both ends of the cardboard box body. The bending plate folds outward using the triangular fold seam to form a triangular part. The cone tip of the triangular part extends into the side hole of the side wall of the cardboard box body to form a locking fit. This achieves the purpose of fixing the folded state without glue, solving the problem that existing foldable cardboard boxes rely on glue for bonding or are easy to loosen after folding.
