Description

Technical Field

[0001] The utility model relates to the technical field of packaging boxes, in particular to a foldable and flattenable packaging box. Background Technique

[0002] As the name implies, a packaging box is a box used to package products. The functions of a packaging box are to ensure the safety of products during transportation and improve the grade of products.

[0003] For example, the Chinese authorized patent (foldable packaging box) with the announcement number CN218464129U: includes a peripheral structure and an inner peripheral structure; the inner peripheral structure is provided with a containing cavity, a bottom opening and a top opening communicated with the containing cavity, and the inner peripheral structure can be switched between a state of unfolding to form a three-dimensional structure of the containing cavity and a state of folding to form a flat plate structure; the peripheral structure is connected to the inner peripheral structure, and the peripheral structure can be switched between a state of wrapping the inner peripheral structure to close the bottom opening and the top opening and a state of unfolding to form a flat plate structure. This foldable packaging box is convenient for assembly and folding switching, which is beneficial to improving the assembly and folding efficiency. In addition, by using the peripheral structure to wrap the inner peripheral structure, a packaging box with a stable structure is formed, which improves the structural strength and load-bearing performance of this foldable packaging box.

[0004] However, most existing packaging boxes have a layer of cover plate. During transportation, the cover plate is prone to force offset and looseness, resulting in poor sealing stability of the packaging box. In addition, the side plates and the cover plate are prone to be bent inward under pressure, and the load-bearing effect is poor. Therefore, it does not meet the existing requirements. For this reason, we propose a foldable and flattenable packaging box. Content of the Utility Model

[0005] The purpose of the utility model is to provide a foldable and flattenable packaging box to solve the problems in the above background technique that most existing packaging boxes have a layer of cover plate. During transportation, the cover plate is prone to force offset and looseness, resulting in poor sealing stability of the packaging box. In addition, the side plates and the cover plate are prone to be bent inward under pressure, and the load-bearing effect is poor.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: A foldable and flattenable packaging box, comprising: a bottom plate, a first side plate is foldably connected to one side of the bottom plate, a second side plate is foldably connected to the other side of the bottom plate, and protective side plates are arranged and connected at the front and rear ends of the bottom plate;

[0007] It further includes:

[0008] An outer cover plate, which is arranged at one end of the first side plate, and the outer cover plate is foldably connected to the first side plate, and an outer fixing plate is foldably connected to one end of the outer cover plate;

[0009] The first inner cover plate is arranged on the upper surface of one end of the first side plate, and the first inner cover plate is foldably connected to the first side plate. One end of the second side plate is foldably connected with a second inner cover plate.

[0010] Preferably, a box cavity is formed in the middle after the bottom plate, the first side plate, the second side plate and the protective side plate are folded, and the upper end of the box cavity is in an open form. The first inner cover plate and the second inner cover plate are folded to seal the opening of the box cavity.

[0011] Preferably, a reinforcing frame is arranged on the inner wall of the protective side plate near the lower end, and the inside of the reinforcing frame is hollow. The reinforcing frame is folded along the bending part.

[0012] Preferably, a first magnetic sheet is arranged on one side of the outer fixing plate, a first iron sheet is arranged on one side of the second side plate, and the outer fixing plate is magnetically connected to the first iron sheet through the first magnetic sheet.

[0013] Preferably, a second iron sheet is arranged on one side of the first inner cover plate, a second magnetic sheet is arranged on one side of the second inner cover plate, and the second inner cover plate is magnetically connected to the second iron sheet through the second magnetic sheet.

[0014] Preferably, pull ropes are arranged at the centers of the tops of the first inner cover plate and the second inner cover plate, and the pull ropes are adhesively fixed to the first inner cover plate and the second inner cover plate through fixing glue.

[0015] Preferably, the pull ropes are flat, and the pull ropes are formed by knitting nylon fibers.

[0016] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0017] 1. In the utility model, an outer cover plate is arranged at one end of the first side plate, and an outer fixing plate is arranged at one end of the outer cover plate. The product to be packaged is placed into the box cavity, the first inner cover plate and the second inner cover plate are covered in sequence. The second inner cover plate is magnetically connected to the second iron sheet of the first inner cover plate through the second magnetic sheet, and the first inner cover plate and the second inner cover plate are supported by the top of the protective side plate, so that they are not easily collapsed by force and the load-bearing effect is improved. Then, the outer cover plate and the outer fixing plate are folded. The outer cover plate covers the first inner cover plate and the second inner cover plate, and the outer fixing plate is magnetically connected to the first iron sheet of the second side plate through the first magnetic sheet, thereby completing the packaging and protection of the product. The outer cover plate protects the first inner cover plate and the second inner cover plate, realizing double protection. Compared with a single first inner cover plate and second inner cover plate, it is not easy to cause the first inner cover plate and the second inner cover plate to be displaced and offset, resulting in the product falling, improving the transportation stability, and solving the problems that most existing packaging boxes have only one layer of cover plate, the cover plate is easily displaced and loosened by force during transportation, resulting in poor sealing stability of the packaging box, and the side plate and the cover plate are easily bent inward under pressure, with poor load-bearing effect.

[0018] 2. By arranging a reinforcing frame on one side of the protective side plate, the inside of the reinforcing frame is hollow. The reinforcing frame is folded along the bending part and forms a hollow cube as the protective side plate unfolds, which has a reinforcing effect on the protective side plate, avoids bending under force, and improves stability.
