Description

Technical Field

[0001] This utility model relates to the technical field of packaging boxes, specifically a packaging box with an anti-deformation structure. Background Technology

[0002] In the logistics and goods storage sector, paper packaging boxes have become the mainstream packaging form for various goods due to their advantages such as low cost, easy recycling, and light weight, and are widely used in industries such as food, electronics, and daily necessities. With the rapid development of the e-commerce industry, the frequency of goods transportation and turnover has increased significantly. Packaging boxes need to withstand multiple tests such as stacking pressure, handling impact, and changes in environmental humidity. Their structural stability is directly related to the integrity of the goods inside. Therefore, improving the deformation resistance of paper packaging boxes has become an important direction for industry optimization.

[0003] Existing paper packaging boxes are mainly made of corrugated cardboard, cardboard and other paper materials through cutting, folding and gluing. The basic structure includes the box body, cover, side panels and bottom panel. Some packaging boxes will have simple reinforcing ribs added to the sides or bottom of the box to enhance the local structural strength. These packaging boxes maintain their shape through the stiffness of the paper material itself and the interlocking strength of the joints. With standardized size design, they can achieve efficient stacking and transportation, meet the packaging needs of general commodities and occupy an important position in the packaging industry.

[0004] Existing paper packaging boxes are prone to deformation in actual use, mainly because the paper material itself has limited tensile and compressive strength. When the packaging box is subjected to the heavy pressure of stacked goods on top, the side panels and bottom panels are prone to dents and collapse due to uneven stress. At the same time, during handling and loading and unloading, if the packaging box is subjected to external impacts such as collisions and squeezing, the paper joints are prone to tearing and deformation, which further aggravates the damage to the box structure and affects the protection of the goods inside.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0039] The embodiments of this utility model will be described below based on its overall structure.

[0040] First embodiment:

[0041] Please see Figures 1-3This embodiment provides a packaging box with an anti-deformation structure, including a packaging box body, wherein the packaging box body is composed of a box body 1 and a box cover 2, a protective mechanism is provided on the box body 1, and a reinforcing mechanism is installed on the box cover 2;

[0042] The reinforcement mechanism includes an end reinforcement plate 4 installed on the end face of the box cover 2, and a side reinforcement plate 41 connected to the end reinforcement plate 4 installed on the side wall of the end reinforcement plate 4; the protection mechanism includes side wall corner protectors 5 installed at the corners of the box body 1, and the side wall corner protectors 5 are installed at all four corners of the box body 1, and support frames 6 are installed on both outer walls of the side wall corner protectors 5, and side support plates 7 that are attached to the box body 1 are installed on the outer walls of the support frames 6; in addition, the outer walls of the end reinforcement plate 4, the side reinforcement plate 41 and the side support plate 7 are all provided with opening grooves 8 for wrapping tape.

[0043] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 Two sets of lids 2 are symmetrically installed at both ends of the box body 1. The corners of both sets of lids 2 are provided with end guards 21 integrally formed with the lids 2. This design can directly withstand the impact force during transportation and reduce the wear and deformation of the corners of the lids 2.

[0044] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 The end face and side wall of the box cover 2 are provided with an inner groove 3, and the end reinforcing plate 4 and the side reinforcing plate 41 are embedded therein. The outer walls of both do not protrude from the surface of the box cover 2, which not only ensures the stability of the reinforcing structure, but also avoids the protruding parts from causing obstruction during stacking or handling.

[0045] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 and Figure 2 The end reinforcement plate 4 is designed in a "+" shape, with each of its four ends connected to a set of side reinforcement plates 41. The ends of the side reinforcement plates 41 are attached to the ends of the side support plates 7. This structure can evenly distribute the pressure on the lid 2 to the side reinforcement plates 41, and then to the side support plates 7 and the side wall corner guards 5, effectively reducing the probability of the lid 2 collapsing.

[0046] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-3 In the protective mechanism, a set of support frames 6 are installed on both outer walls of the side support plate 7. Each set of support frames 6 includes two brackets, which connect the side support plate 7 and the side wall corner guard 5 into a whole. When the side wall of the box 1 is subjected to force, the side support plate 7 can transmit the force to the side wall corner guard 5 through the support frame 6 to avoid the side wall from being dented due to local pressure.

[0047] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 and Figure 3The protective mechanism also includes an inner wall corner protector 9 installed inside the box 1, corresponding to the position of the side wall corner protector 5. A rubber strip 10 is installed at the corner of the inner wall corner protector 9 with glue, and both the side wall corner protector 5 and the inner wall corner protector 9 are equipped with magnets that attract each other. The attraction of the magnets causes the two to clamp the corners from the inside and outside of the box 1. Combined with the buffering effect of the rubber strip 10, it can not only enhance the bending resistance of the corners, but also reduce the impact of the items inside the box on the inner wall of the box 1.

[0048] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-3 The end reinforcing plate 4, side reinforcing plate 41, side wall corner protector 5, support frame 6, side support plate 7 and inner wall corner protector 9 are all made of rigid plastic or metal plate. These materials themselves have high rigidity and can effectively resist external deformation, complementing the paper box 1.

[0049] Second embodiment:

[0050] Please see Figures 1-6 This embodiment provides a packaging box with an anti-deformation structure. The technical solution and parts of this embodiment are basically the same as those of Embodiment 1. The technically similar parts will not be repeated here. The difference is that the rubber strip 10 in this embodiment can be detachably installed at the corner of the inner wall corner protector 9. Specifically, multiple sets of screws 12 are slidably installed on the inner wall corner protector 9. The inner wall of the side wall corner protector 5 has threaded holes 14 corresponding to the screws 12. After the screws 12 pass through the inner wall corner protector 9 and the box body 1, they are connected to the threaded holes 14, which further strengthens the position of the side wall corner protector 5 and the inner wall corner protector 9, ensuring that they do not loosen when subjected to force.

[0051] For details regarding the above embodiments, please refer to [link / reference]. Figures 4-6 The rubber strip 10 has a mounting groove 11 corresponding to the screw 12, and the inner wall corner guard 9 has a mounting hole 13 for the screw 12 to pass through. Because the diameter of the mounting groove 11 is larger than the maximum diameter of the screw 12, and the end of the screw 12 does not protrude from the mounting groove 11, it avoids scratching the items inside the box.

[0052] In practical operation, the protective and reinforcing mechanisms work together when the packaging box is subjected to stacking pressure or external compression. The side wall corner protectors 5 and the inner wall corner protectors 9 are double-fixed by screws 12 and magnets, forming rigid support for the corners of the box body 1, resisting bending forces at the corners and preventing the box body 1 from collapsing due to corner deformation. The support frame 6 connects the side support plate 7 to the side wall corner protectors 5. The side support plate 7 fits against the side wall of the box body 1, distributing the pressure on the side wall to the side wall corner protectors 5 at the corners, reducing the probability of side wall denting and deformation.

[0053] Meanwhile, the end reinforcing plate 4 and side reinforcing plate 41 on the lid 2 enhance the bending resistance of the lid 2. When the lid 2 is under pressure, the cross-shaped end reinforcing plate 4 can evenly distribute the pressure to the four side reinforcing plates 41, and then transmit it to the side support plate 7 and the side wall corner guard 5, thereby reducing the probability of the lid 2 collapsing.

[0054] Because the outer walls of the end reinforcing plate 4, the side reinforcing plate 41, and the side support plate 7 are all provided with opening grooves 8, when the tape is wrapped, the tape can be embedded in the opening grooves 8, increasing the friction between the tape and the reinforcing structure and preventing the tape from loosening; at the same time, the tape further binds the reinforcing mechanism and the protective mechanism, making the box body 1 and the box cover 2 form an integral rigid structure, improving the overall resistance to deformation. Moreover, because the tape is completely located in the opening grooves 8, the tape will not directly rub against the ground, the placement surface of the transport device, etc., thus effectively avoiding accidents caused by the movement of the packaging box during handling and transportation, resulting in tape wear and damage.

[0055] During handling, if the packaging box is impacted, the end corner protectors 21 and the side wall corner protectors 5 can directly withstand the impact force, reducing direct damage to the box body 1 and the box lid 2; the rubber strips 10 inside the inner wall corner protectors 9 can buffer the impact of the items inside the box on the inner wall of the box body 1, preventing the inner wall from deforming due to the collision of the items.

[0056] The side wall corner protectors 5 and the inner wall corner protectors 9 clamp the corners from the inside and outside of the box body 1, forming a sandwich-type corner protection with the rigid connection of screws 12; while the support frame 6 and the side support plate 7 transfer the force of the side wall to the corners, avoiding excessive local force and deformation; at the same time, the reinforcing mechanism of the box cover 2, through its fit with the side support plate 7, realizes the force transmission between the box cover 2 and the box body 1, ensuring that the pressure is evenly distributed when stacked.

[0057] During assembly, firstly, the protective mechanism of the box 1 is assembled, and the four side wall corner protectors 5 are respectively attached to the four corners of the box 1 to ensure that their outer walls are tightly attached to the outer walls of the box 1; then, the inner wall corner protectors 9 are placed inside the box 1 so that they correspond to the positions of the side wall corner protectors 5. At this time, the magnetic magnets inside the inner wall corner protectors 9 and the side wall corner protectors 5 will attract each other, initially fixing their positions.

[0058] Next, screws 12 are inserted through mounting holes 13 on the inner wall corner protector 9. After passing through the box body 1, screws 12 are threaded into the threaded holes 14 on the inner wall of the side wall corner protector 5, thus firmly fixing the inner wall corner protector 9 and the side wall corner protector 5 to the inner and outer walls of the box body 1. At this time, the mounting groove 11 on the rubber strip 10 provides space for the screws 12, and the end of the screws 12 does not protrude from the mounting groove 11 to avoid scratching the items inside the box.

[0059] When the reinforcing mechanism of the box cover 2 is installed, first embed the side reinforcing plate 41 into the inner groove 3 of the side wall of the box cover 2, and then embed the "+" shaped end reinforcing plate 4 into the inner groove 3 of the end face of the box cover 2 to ensure that the end reinforcing plate 4 and the outer wall of the side reinforcing plate 41 do not protrude from the surface of the box cover 2.

[0060] This packaging box features a multi-layered anti-deformation structure with reinforced corners, side supports, and a reinforced top cover. Combined with material properties and force transmission design, it effectively resists deformation caused by external forces such as stacking pressure and handling impacts. This solves the problem of poor deformation resistance of traditional paper packaging boxes, providing reliable protection for the contents. It is suitable for logistics transportation, warehousing, and other scenarios.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
