Description

Technical Field

[0001] This utility model relates to the field of paper box technology, specifically to a scratch-resistant structure for the surface of a paper box. Background Technology

[0002] Existing cardboard packaging is prone to scratches on its surface during transportation, stacking, or handling due to friction or external forces, resulting in damage to its appearance or a decrease in functionality.

[0003] Traditional solutions such as surface lamination or coating, while improving scratch resistance to some extent, are complex to process, costly, or have limited protective effects. Secondly, traditional surface lamination usually adopts a tight-fitting design, that is, the lamination is directly attached to the surface of the cardboard box. External forces (such as friction or impact) can be transmitted through the lamination to the surface of the cardboard box, causing scratches or dents to still occur on the surface of the cardboard box, thus causing the protection to fail. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a scratch-resistant structure for paper box surfaces. Traditional solutions such as surface coating or plating can improve scratch resistance to some extent, but they are complex to process, costly, or have limited protective effects. Furthermore, traditional surface coating usually adopts a tight-fitting design, that is, the coating is directly attached to the surface of the paper box. External forces (such as friction or collision) will be transmitted through the coating to the surface of the paper box, causing scratches or dents to still occur on the surface of the paper box, thus causing the protection to fail.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a scratch-resistant structure for the surface of a paper box, comprising:

[0006] A cardboard box, the cardboard box comprising a box body and a box lid disposed on the box body;

[0007] The upper frame is fitted onto the top edge of the box lid;

[0008] The lower frame is fitted onto the bottom edge of the box body;

[0009] Multiple elastic locking straps are arranged sequentially and at intervals between the upper and lower frames, and four of the locking straps are located on the four edges of the cardboard box.

[0010] Reinforcing ribs are respectively provided on the top of the lid and the bottom of the box body, wherein the reinforcing ribs include cross-shaped convex ribs;

[0011] A transparent wrapping film covers the outside of the upper and lower frames.

[0012] The beneficial effects of this utility model are:

[0013] 1) By fitting upper and lower frames of a certain thickness onto the top of the box lid and the bottom of the box body respectively, and setting a locking band of a certain thickness and elasticity between the upper and lower frames, and designing ribs on the box lid and box body, a protective structure of a certain thickness can be pre-built on the outside of the box. On this basis, when the upper and lower frames are covered with a transparent wrapping film, an isolation layer with a certain space can be formed between the wrapping film and the surface of the box. The wrapping film combined with the isolation layer can effectively block external friction or impact forces, not only absorbing and dispersing external impact forces, but also ensuring that external forces only act on the surface of the wrapping film and are not directly transmitted to the surface of the box, thereby significantly reducing the possibility of scratches on the surface of the box. Compared with the traditional tight-fitting film method, the design based on the isolation layer effectively solves the problem of external forces directly acting on the surface of the box through the film, providing a better protection effect for the box.

[0014] 2) At the same time, the elastic tension of the locking rope is used to tightly connect the upper and lower frames and apply opposing clamping forces to the box body and the box cover, which effectively prevents the box cover and the box body from separating due to vibration or external force during transportation or handling, and ensures the stability of the paper box structure.

[0015] Based on the above technical solution, the present invention can be further improved as follows.

[0016] Furthermore, both the upper frame and the lower frame are composed of a first cover plate and a second cover plate in a U-shape.

[0017] Furthermore, the second cover plate is fixed to the bottom of the first cover plate.

[0018] The beneficial effect of adopting the above-mentioned further solutions is that it can effectively protect the edges and corners of the cardboard box, reduce the problem of edge wear or deformation caused by external impact or squeezing during transportation or storage, not only improve the overall pressure resistance, but also provide additional cushioning protection for the edges of the cardboard box.

[0019] Furthermore, the thickness of both the first cover plate and the second cover plate is not less than 3cm.

[0020] Furthermore, the diameter of the locking band is not less than 3cm.

[0021] Furthermore, the thickness of the rib is not less than 3 cm.

[0022] The beneficial effect of adopting the above-mentioned further solution is that, through the thickened cover plate, locking strap, and ribs, a certain gap can be maintained between the wrapping film and the cardboard box, thereby forming an effective isolation space.

[0028] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0029] Existing cardboard packaging is prone to scratches on its surface during transportation, stacking, or handling due to friction or external forces, resulting in damage to its appearance or a decrease in functionality.

[0030] Traditional solutions such as surface lamination or coating, while improving scratch resistance to some extent, suffer from complex processing, high cost, or limited protective effect. Furthermore, traditional surface lamination usually adopts a close-fitting design, meaning the lamination is directly adhered to the surface of the cardboard box. External forces (such as friction or impact) can be transmitted through the lamination to the surface of the cardboard box, causing scratches or dents to still occur on the surface, thus rendering the protection ineffective. To address these issues, the inventor has proposed a scratch-resistant structure for the surface of cardboard boxes.

[0031] The present invention provides the following preferred embodiments.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, a scratch-resistant structure for a paper box surface includes:

[0033] Paper box 10, which includes a box body 101 and a box cover 102 disposed on the box body 101;

[0034] The upper frame 20 is fitted onto the top edge of the box cover 102;

[0035] The lower frame 30 is fitted onto the bottom edge of the box body 101;

[0036] Multiple elastic locking straps 40 are arranged sequentially and at intervals between the upper frame 20 and the lower frame 30, and four locking straps 40 are located on the four edges of the cardboard box 10 respectively. The locking straps 40 may be made of rubber.

[0037] Reinforcing ribs 50 are respectively provided on the top of the lid 102 and the bottom of the body 101. The reinforcing ribs 50 include cross-shaped protruding ribs.

[0038] A transparent wrapping film 60 covers the outside of the upper frame 20 and the lower frame 30;

[0039] By fitting an upper frame 20 and a lower frame 30 of a certain thickness onto the top of the lid 102 and the bottom of the body 101 of the cardboard box 10 respectively, and setting a locking strap 40 of a certain thickness and elasticity between the upper frame 20 and the lower frame 30, and designing protruding ribs on the lid 102 and the body 101, a protective structure of a certain thickness can be pre-constructed on the outside of the cardboard box 10. On this basis, when the upper frame 20 and the lower frame 30 are covered with a transparent wrapping film 60, an isolation layer with a certain space can be formed between the wrapping film 60 and the surface of the cardboard box 10. The wrapping film 60 combined with the isolation layer can effectively block external friction or impact forces, not only absorbing and dispersing external impact forces, but also ensuring that external forces only act on the surface of the wrapping film 60 and are not directly transmitted to the surface of the cardboard box 10, thereby significantly reducing the possibility of scratches on the surface of the cardboard box 10. Compared with the traditional tight-fitting film method, the design based on the isolation layer effectively solves the problem of external forces directly acting on the surface of the cardboard box 10 through the film, providing a better protection effect for the cardboard box 10.

[0040] At the same time, the elastic tension of the locking rope is used to tightly connect the upper frame 20 and the lower frame 30, and to apply opposing clamping forces to the box body 101 and the box cover 102, which effectively prevents the box cover 102 and the box body 101 from separating due to vibration or external force during transportation or handling, thus ensuring the stability of the paper box 10 structure.

[0041] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, both the upper frame 20 and the lower frame 30 are composed of a first cover plate and a second cover plate in the shape of a U-shape. The second cover plate is fixed to the bottom of the first cover plate. The cross-section of the upper frame 20 is inverted L-shape, while the cross-section of the lower frame 30 is L-shape. This effectively protects the edges and corners of the paper box 10 and reduces the wear or deformation of the edges and corners caused by external impact or squeezing during transportation or storage. This not only improves the overall pressure resistance but also provides additional cushioning protection for the edges of the paper box 10.

[0042] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the thickness of the first cover plate and the second cover plate is not less than 3cm, the diameter of the locking band 40 is not less than 3cm, and the thickness of the rib is not less than 3cm. Through the thickened cover plate, the locking band 40, and the rib, it can be ensured that a certain gap is maintained between the wrapping film 60 and the cardboard box 10, thereby forming an effective isolation space.

[0043] The specific working process of this utility model is as follows:

[0044] By fitting an upper frame 20 and a lower frame 30 of a certain thickness onto the top of the lid 102 and the bottom of the body 101 of the cardboard box 10 respectively, and setting a locking strap 40 of a certain thickness and elasticity between the upper frame 20 and the lower frame 30, and designing protruding ribs on the lid 102 and the body 101, a protective structure of a certain thickness can be pre-constructed on the outside of the cardboard box 10. On this basis, when the upper frame 20 and the lower frame 30 are covered with a transparent wrapping film 60, an isolation layer with a certain space can be formed between the wrapping film 60 and the surface of the cardboard box 10. The wrapping film 60 combined with the isolation layer can effectively block external friction or collision forces and absorb and disperse external impact forces.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
