Description

Technical Field

[0001] The utility model relates to the technical field of cartons, in particular to a high-strength anti-tear recyclable carton. Background Technique

[0002] In the fields of modern logistics and commodity packaging, cartons, as a widely used packaging material, play a crucial role.

[0003] The existing Chinese patent (Publication No.: CN220786469U) discloses an anti-tear carton, including a carton body. A carton cover plate is arranged at the top of the carton body. Holding holes are formed on both sides of the carton body. The carton body includes a buffer layer. An anti-tear layer is arranged in the inner cavity of the buffer layer. A protective layer is arranged on the surface of the buffer layer. The anti-tear layer includes a tensile layer. The surface of the tensile layer is adhered to the buffer layer. A reinforcing layer is adhered in the inner cavity of the tensile layer. A compressive layer is adhered in the inner cavity of the reinforcing layer. The material of the compressive layer is foam cardboard. The material of the reinforcing layer is cardboard. By adopting the compressive layer, the reinforcing layer and the tensile layer, the utility model can play a role in anti-tearing, and can effectively prevent the carton body from being torn by external force. By adopting the waterproof layer, the anti-puncture layer and the wear-resistant layer, the utility model can play a role in protecting the surface of the carton body, and can effectively prevent the surface of the carton body from being damaged.

[0004] Although the above-mentioned carton improves the strength of the carton to a certain extent by setting multiple protective layers during use, it has certain defects when dealing with the scenario of large-scale cargo stacking. When a large number of cartons are stacked together, due to the weight of the goods themselves and unreasonable stacking methods, the bottom cartons will bear huge pressure. Without effective buffering measures, these pressures are concentrated on the side walls and corners of the cartons, and it is easy to cause the cartons to be torn. Content of the Utility Model

[0005] The purpose of the utility model is to provide a high-strength anti-tear recyclable carton to solve the problems raised in the above background technique.

[0006] To solve the above technical problems, a high-strength anti-tear recyclable carton provided by the utility model includes a carton body and a cover plate connected to the carton body, including,

[0007] A plurality of reinforcing gaskets, which are triangular and rotatably arranged in the carton body, corresponding to the inner corners of the carton body. As the reinforcing gaskets rotate, the reinforcing gaskets and the carton body form an independent triangular support space;

[0008] Limit grooves are formed on the inner corner edges of the carton body for limiting the reinforcing gaskets;

[0009] The buffer air bags are connected in a rectangular array inside the cover plate. A sliding plate is slidably connected to the cover plate. As the goods are stacked, the sliding plate slides vertically to squeeze the buffer air bags.

[0010] Furthermore, reinforcing strips are connected to four sides of the carton body, and the reinforcing strips are in a cross shape.

[0011] Furthermore, it further includes an anti-wear component, which includes a plurality of wear-resistant strips inserted at the bottom of the carton body. First limit blocks and second limit blocks are connected to the bottom of the carton body. The first limit block and the second limit block are respectively located on the left and right sides of the wear-resistant strip. A limit column is slidably connected to the second limit block. One end of the limit column penetrates through the wear-resistant strip and extends into the first limit block. A force-applying block is connected to the other end of the limit column. A compression spring is sleeved on the limit column, and two ends of the compression spring are respectively connected to the second limit block and the force-applying block.

[0012] Furthermore, connection bumps are connected to the reinforcing gasket, and anti-slip patterns are integrally formed on the connection bumps. The connection bumps are used to pull the reinforcing gasket.

[0013] Furthermore, two symmetrically arranged buckle grooves are formed in the carton body, and chamfers are formed in the buckle grooves.

[0014] Furthermore, two symmetrically arranged reinforcing gaskets are connected to the carton body, and the positions of the reinforcing gaskets correspond to the buckle grooves.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. In the stacking scenario, it can effectively disperse the pressure of the upper carton, decompose the vertical pressure, reduce the extrusion on the side walls and the bottom, and reduce the risk of the carton being crushed or torn. At the same time, the strength and rigidity at the corners are enhanced, resisting external force deformation like a reinforcing rib, greatly protecting the structural integrity of the carton during handling and stacking, ensuring the safety of the internal goods and extending the service life of the carton.

[0017] 2. The wear-resistant strips that are convenient to replace can ensure that the carton always maintains good wear resistance during long-term use. When the wear is serious, it can be quickly replaced without replacing the whole carton, reducing the cost. At the same time, it is conducive to recycling, conforms to the environmental protection concept, and improves the resource utilization rate. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation manner

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-6 , the present utility model provides a technical solution: a high-strength anti-tear recyclable carton, including a carton body 1 and a cover plate 16 covered on the carton body 1, including,

[0027] A plurality of reinforcing gaskets 2, which are triangular and rotatably arranged in the carton body 1 and correspond to the inner corners of the carton body 1. As the reinforcing gasket 2 rotates, the reinforcing gasket 2 and the carton body 1 form an independent triangular support space;

[0028] Limiting grooves 3 are opened on the inner corner edges of the carton body 1 for limiting the reinforcing gaskets 2;

[0029] Buffer airbags 6 are connected in the cover plate 16 in a rectangular array, and a sliding plate 5 is slidably connected to the cover plate 16. As the goods are stacked, the sliding plate 5 slides vertically to squeeze the buffer airbags 6.

[0030] Preferably, a first small magnetic sheet can be connected in the limiting groove 3, and a second small magnetic sheet can be connected on the reinforcing gasket 2. By the cooperation of the two magnetic sheets, the reinforcing gasket 2 can be clamped in the limiting groove 3.

[0031] It should be noted that in the present utility model, the reinforcing gaskets 2 can preferably be four and are respectively arranged at the bottom of the carton body 1, or can be eight and are respectively arranged at the top and bottom of the carton body 1, and can be selected according to the actual situation.

[0032] During specific implementation, when the carton is not loaded with goods and not stacked, the reinforcing gaskets 2 are in the initial position where they can rotate freely. At this time, they are attached to the corresponding positions on the inner wall of the carton body 1, without affecting the normal storage and storage space of the carton. When goods need to be stored, the reinforcing gaskets 2 can be rotated to form a triangular support space. When the cartons loaded with goods start to be stacked, when the cartons are stacked, the triangular space formed by the reinforcing gaskets 2 and the corners can disperse the pressure of the upper carton to a larger area, so that the pressure originally acting vertically on the top corners of the carton body 1, through the supporting action of the inclined pieces, is decomposed into a component force along the direction of the reinforcing gasket 2 and a component force perpendicular to the direction of the reinforcing gasket 2. In this way, the pressure perpendicular to the side wall of the carton body 1 will be reduced, thereby reducing the direct extrusion on the side wall and bottom of the carton body 1 and reducing the risk that the carton body 1 is crushed or torn due to excessive pressure.

[0033] At the same time, the presence of the reinforcing gaskets 2 increases the strength and rigidity of the corners of the carton body 1. During the handling and stacking of the carton body 1, the corners are prone to being collided and squeezed and deformed. The reinforcing gaskets 2 form a structure similar to a reinforcing rib through connection with the carton body 1, and can effectively resist the deformation caused by external forces.

[0034] Reference Figure 1 As shown, reinforcing strips 4 are connected to the four side surfaces of the carton body 1, and the reinforcing strips 4 are in a cross shape.

[0035] During specific implementation, the cross-shaped reinforcing strips 4 can provide comprehensive supporting force for the four side surfaces of the carton body 1. When the carton body 1 is subjected to external extrusion, such as collision during handling or pressure from the upper carton during stacking, the reinforcing strips 4 can disperse these external forces to a larger area and reduce local stress concentration.

[0036] Reference Figure 2 and Figure 5 As shown, it further includes an anti-wear component, which includes a plurality of wear-resistant strips 7 inserted at the bottom of the carton body 1. A first limit block 8 and a second limit block 9 are connected to the bottom of the carton body 1. The first limit block 8 and the second limit block 9 are respectively located on the left and right sides of the wear-resistant strip 7. A limit post 10 is slidably connected to the second limit block 9. One end of the limit post 10 penetrates through the wear-resistant strip 7 and extends into the first limit block 8. The other end of the limit post 10 is connected to a force application block 11. A compression spring 12 is sleeved on the limit post 10, and the two ends of the compression spring 12 are respectively connected to the second limit block 9 and the force application block 11.

[0037] During specific implementation, during the process of pulling and carrying the carton body 1, the bottom of the carton body 1 will be worn, thus affecting its overall strength. Therefore, wear-resistant strips 7 are designed to improve the wear resistance of the carton body 1;

[0038] When the wear-resistant strip 7 is severely worn, it needs to be replaced. At this time, by pulling the force-applying block 11, the limiting post 10 is no longer in contact with the wear-resistant strip 7, and the wear-resistant strip 7 can be pulled out of the carton body 1 for replacement again, which is convenient for recycling.

[0039] Reference Figure 6 , a connecting convex block 13 is connected to the reinforcing gasket 2. Anti-slip patterns are integrally formed on the connecting convex block 13, and the connecting convex block 13 is used to pull the reinforcing gasket 2.

[0040] During specific implementation, the set connecting convex block 13 facilitates pulling the reinforcing gasket 2 to rotate.

[0041] Reference Figures 1 to 2 , two symmetrically arranged buckle grooves 14 are formed on the carton body 1, and chamfers are formed in the buckle grooves 14.

[0042] During specific implementation, the set buckle grooves 14 facilitate applying force to pick up or lift the carton body 1, and the set chamfers are used to protect the user's hand from being easily scratched.

[0043] Reference Figures 1 to 2 , two symmetrically arranged reinforcing gaskets 15 are connected to the carton body 1, and the positions of the reinforcing gaskets 15 correspond to the buckle grooves 14.

[0044] During specific implementation, the set reinforcing gaskets 15 improve the strength of the buckle grooves 14 and prevent the buckle grooves 14 from being damaged when lifting and pulling the carton body 1.

[0045] Working principle: When the carton is not loaded with goods and not stacked, the reinforcing gaskets 2 are in the initial position where they can rotate freely. At this time, they fit on the corresponding positions of the inner wall of the carton body 1 without affecting the normal storage and storage space of the carton. When goods need to be stored, the reinforcing gaskets 2 can be rotated to form a triangular support space. When the cartons with goods start to be stacked, when the cartons are stacked, the triangular space formed by the reinforcing gaskets 2 and the corners can disperse the pressure of the upper carton to a larger area, so that the pressure originally acting vertically on the top corners of the carton body 1 is decomposed into a component force along the direction of the reinforcing gasket 2 and a component force perpendicular to the direction of the reinforcing gasket 2 through the support of the inclined piece. In this way, the pressure perpendicular to the side wall of the carton body 1 will be reduced, thereby reducing the direct extrusion on the side wall and bottom of the carton body 1 and reducing the risk of the carton body 1 being crushed or torn due to excessive pressure;

[0046] Meanwhile, the presence of the reinforcing gasket 2 increases the strength and rigidity of the corners of the carton body 1. During the handling and stacking of the carton body 1, the corners are prone to being collided and squeezed, resulting in deformation. Through the connection with the carton body 1, the reinforcing gasket 2 forms a structure similar to a reinforcing rib, which can effectively resist the deformation caused by external forces;

[0047] When the wear-resistant strip 7 is severely worn, it needs to be replaced. At this time, by pulling the force-applying block 11, the limiting post 10 is no longer in contact with the wear-resistant strip 7, and the wear-resistant strip 7 can be pulled out from the carton body 1 for replacement again, which is convenient for recycling.
