Description

A foldable packaging box

technical field

The utility model belongs to the technical field of packaging, in particular to a folding packaging box.

Background technique

Most of the existing packaging boxes, such as various gift packaging boxes and various digital product packaging boxes, are hexahedral structures. Except for the free movement of the box cover, the other sides are fixedly connected to each other, and their shapes are fixed and cannot be unfolded or folded. , takes up a lot of space when not in use, is extremely inconvenient to store, and is formed by glue bonding, all of which are disposable products and cannot be reused, resulting in a lot of waste of resources.

In view of the above-mentioned problems, Chinese patent No. 03233772.8 proposes a technical solution called "foldable packaging box". This scheme includes a box body, a box bottom, and a box cover. There is a roughly diagonal indentation line at one corner of the upper and lower flaps at the bottom of the box, and the upper and lower flaps are bonded to the left or right flaps on one side respectively. The two parts after bonding are alternately laminated in sequence when the box is opened. There is a roughly diagonal indentation line at one corner of the upper and lower flaps at the bottom of the box. The upper and lower flaps are respectively connected to the left or right flaps on one side. After the connection, the two parts are opened staggered in sequence. A protruding part protruding from the center line is provided on the upper flap plate and/or the edge, and when the flap plates are stacked alternately, the protruding portion inserts into the lower edge line of the other side and engages with each other. The protruding parts of the edge line of the flap are located on the other side of the indentation line respectively, and the side near the middle is parallel to the indentation line. The packaging box disclosed by the scheme can withstand relatively large external force and can be folded. However, this solution still has some disadvantages, such as difficulty in ensuring stability due to the interlocking connection of various parts, relatively complicated structure, and high processing cost.

Utility model content

The technical problem to be solved by the utility model is to provide an easy-to-use and foldable packing box.

According to above-mentioned technical requirement, the utility model adopts following technical scheme to realize:

A folding packaging box mainly includes a box bottom, a box cover, left and right box walls, and front and rear box walls. The box bottom, box cover, left and right box walls, and front and rear box walls are integrated. The indentation line of folding, the left and right box walls and the front and rear box walls are respectively connected by a connecting body. The wall connection is an indentation line with a thinner thickness for easy bending. The connecting body is bonded to the inner wall of the front box wall, and the connecting body is integrated with the side edges of the left and right box walls. The utility model is plate-shaped in a fully unfolded state, and the left and right box walls are attached to the bottom of the box in parallel. When the front and rear box walls are turned inwardly and erected relative to the box bottom, the left and right box walls are also turned inwardly and erected under the action of the connecting body, so that a square cavity is formed inside the packaging box. Now the connecting body plays the role of supporting the left and right box walls to prevent the left and right box walls from tilting.

As an improvement to the above-mentioned scheme, a flap is provided at the front of the lid. Between the flap and the lid is an indentation line that is thinner and easier to bend. Magnets that attract each other are fixed inside the flip and inside the front box wall. The relative position of the flip cover and the front box wall is fixed by the mutual attraction of the magnets, which can ensure the stability of the box cover position and the stability of the entire packaging box structure.

The utility model has the advantages of simple structure, ingenious design, rigorous and reasonable structure, all sides of the packaging box can be unfolded, and its unfolded state is flat, which occupies a small space and is convenient for storage and transportation; at the same time, under the action of the connecting body, it is very convenient to unfold and close , and also make the relative position of each part more stable.

Accompanying drawing 1 is the structural diagram of the folded state of the embodiment of the utility model; the accompanying drawing 2 is the structural diagram of the partially unfolded state of the embodiment; the accompanying drawing 3 is the structural diagram of the fully unfolded state of the embodiment.

Detailed ways

In order to facilitate the understanding of those skilled in the art, the structural principle of the utility model will be further described in detail below in conjunction with specific embodiments and accompanying drawings:

As shown in accompanying drawings 1 to 3, the scheme disclosed in this embodiment can be a plane when fully unfolded, and a hexahedron structure in a folded use state. The scheme is mainly composed of front box bottom 1, box cover 2, left and right box walls 3, front and rear box walls 4 and flip cover 5 positioned at the front part of box cover 2.

The left and right box walls 3 and the front and rear box walls 4 are respectively located on the left, right, front and rear edges of the box bottom 1, and are integrated with the box bottom 1, and the thickness of the connecting parts is relatively thin to form an indentation line 7, so that the left and right box walls 3, front and rear The box wall 4 can be turned relative to the bottom 1 of the box. The lid 2 is integrated with the rear box wall, and the junction is a thinner indentation line. The flip cover 5 is integrated with the other side of the lid 2, and the joint is also a thinner indentation line. In order to make the flip cover 5 fit well with the front box wall after being closed, magnets 51, 41 that can attract each other are fixed inside the flip cover 5 and the front box wall.

In order to make the left and right side walls 3 and the front and rear box walls 4 flipping interlockingly, and keep the left and right side walls 3 and the front and rear side walls 4 upright in the closed state, a connecting body 6 is provided between the left and right side walls 3 and the front and rear box walls 4 , that is, connectors 6 are provided on the four corners of the packing box. The connecting body 6 is in the shape of a right triangle, and the right angle side is connected with the side edges of the left and right box walls 3 as a whole, and the junction is an indentation line. The other right-angled side is connected with the front and back box wall 4 inner walls, and makes the connecting body 6 turn over relative to the inner wall.

When fully unfolded, the packaging box as a whole is plate-shaped, the left and right box walls 3 are attached to the box bottom 1 in parallel, the front and rear box walls 4 are located on both sides of the box bottom 1, and the box cover 2 and flip cover 5 are located on the rear side of the rear box wall in turn. . When the front and rear box walls 4 are turned inwardly relative to the box bottom 1 and are erected, the connecting body 6 is erected relative to the front and rear box walls 4, thereby driving the left and right box walls 3 to turn up and erect relative to the box bottom 1, finally forming a square shape inside the packaging box. cavity.

In this solution, the connecting body 6 is a key component, through which the linkage between the front and rear box walls 4 and the left and right box walls 3 is realized, thereby forming the enclosing structure required by the packaging box. Except for the position of the indentation line, each part is a plate with a certain hardness, and the material of the plate can be paper, plastic or metal. The creasing line can be a soft paper or a cloth strip with a certain strength.
