Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, specifically a deformation-resistant packaging box. Background Technology

[0002] Packaging boxes refer to containers used for product packaging. They can be classified into categories such as paper boxes, iron boxes, wooden boxes, and cloth boxes according to materials. According to their uses, they cover more than ten industries such as food, medicine, and daily chemicals. Their core functions include transportation protection, quality improvement, and display.

[0003] An investigation revealed that a utility model patent (publication number: CN220263471U) discloses a deformation-resistant packaging box with a cushioning structure. The box includes a packaging body comprising a first base layer, a double-coated paper layer on top of the first base layer, and a kraft paper layer at the bottom of the first base layer. A protective edging is provided at the lower end of the outer surface of the packaging body. This protective edging includes a second base layer, an epoxy resin layer on top of the second base layer, and a high-density polyethylene layer at the bottom of the second base layer. The double-coated paper layer on top of the first base layer and the kraft paper layer at the bottom of the first base layer provide the packaging box with cushioning and deformation-resistant properties, achieving excellent cushioning and deformation-resistant effects. This solves the problem that existing packaging boxes lack sufficient cushioning and deformation-resistant functions, failing to meet user needs.

[0004] Although the aforementioned patent has implemented a cushioning and anti-deformation structure at the bottom of the box, the pressure on the packaging box is not limited to the bottom. The top and sides of the packaging box will still be deformed by external pressure, thereby reducing the safety of the packaging box and easily causing damage to the contents inside.

[0005] Therefore, this utility model provides a deformation-resistant packaging box to solve the above problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1-4 As shown, this utility model provides a deformation-resistant packaging box, including an outer box body 1, the top of which is covered by an outer box cover 11; a reinforcing component 2, which is filled inside the outer box body 1 and serves as auxiliary reinforcement at the corners and edges of the outer box body 1, and is filled with a sponge tube 3; an inner box body 4, which is inserted into the sponge tube 3 and is covered by an inner box cover 41; a first cover plate 31 and a second cover plate 32, which are staggered and connected to the top sides of the sponge tube 3, and are folded over the top of the inner box cover 41. Through the arrangement of the inner and outer layer structures, the packaging safety of the inner box body 4 is improved under the protection of the reinforcing component 2 and the sponge tube 3, thus avoiding damage to the packaged items.

[0020] Furthermore, the reinforcing component 2 includes a reinforcing base plate 21, which is located at the bottom inner side of the outer casing 1. Reinforcing posts 22 are fixedly connected to the upper corners of the reinforcing base plate 21, and reinforcing rods 23 are connected between adjacent reinforcing posts 22. A reinforcing cover plate 24 is connected to the top of the reinforcing posts 22, and the reinforcing cover plate 24 covers the top of the first cover plate 31 and the second cover plate 32. The reinforcing posts 22 have a right-angle structure, and L-shaped slots are arrayed on both sides of the reinforcing posts 22. Reinforcing rods 23 are inserted into the L-shaped slots and fit snugly against the surface. The inner wall of the outer box 1 has a downward-facing insertion hole at the top of the reinforcing column 22. A damping shaft 25 is fixedly connected to the bottom corner of the reinforcing cover 24 corresponding to the insertion hole, and the damping shaft 25 is damped and inserted into the insertion hole. Through the assembly structure of the reinforcing component 2, the top reinforcing cover 24 can be disassembled and assembled with the opening and closing of the outer box cover 11. Thus, the reinforcing component 2 provides auxiliary support to the inside of the outer box 1, improves the deformation resistance of the outer box 1, avoids deformation of the outer box 1 due to external impacts, and further improves the packaging safety of the inner box 4.

[0021] Furthermore, the reinforcing base plate 21 and the reinforcing cover plate 24 have the same structure, and the corners of the reinforcing base plate 21 and the reinforcing cover plate 24 are triangular structures. The inner diameter of the triangular structure is smaller than the inner diameter of the opening of the inner box 4, ensuring that the reinforcing component 2 can provide good protection for the inner box 4 when it is wrapped.

[0022] Furthermore, the side array of the sponge tube 3 is provided with limiting strips 33, and the limiting strips 33 fill between adjacent reinforcing rods 23. The upper surface of the first cover plate 31 is provided with a slot adapted to the second cover plate 32, and the second cover plate 32 is folded over and covers the top of the first cover plate 31. The thickness of the second cover plate 32 is less than the thickness of the first cover plate 31. The sponge tube 3 wraps around the outside of the inner box 4, the reinforcing component 2 covers the outside of the sponge tube 3, and the reinforcing cover plate 24 is fixedly connected to the top of the inner box cover 11. When the item is placed inside the inner box 4, the top of the inner box 4 is first covered by the inner box cover 41, then the first cover plate 31 is folded, then the second cover plate 32 is folded, and finally the outer box 1 is closed. When the outer box 1 is closed, the reinforcing cover plate 24 covers the top of the second cover plate 32 and the first cover plate 31, and while assisting in pressing the first cover plate 31 and the second cover plate 32, it achieves all-round wrapping protection for the inner box 4.

[0023] Working principle: First, items are placed inside the inner box 4, and then the inner box cover 41 is closed. Then, the first cover plate 31 and the second cover plate 32 are folded over and covered, so that the first cover plate 31 and the second cover plate 32 cover the top of the inner box cover 41 in sequence. Finally, the outer box cover 11 is closed. While the outer box cover 11 is closed, the damping shaft 25 and the reinforcing column 22 are interlocked and cooperate with each other, so that the reinforcing cover plate 24 covers the top of the first cover plate 31 and the second cover plate 32. While assisting in pressing the first cover plate 31 and the second cover plate 32, the inner box 4 is fully wrapped, thereby improving the deformation resistance of the packaging box and improving its packaging safety.

[0024] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
