Description

Technical Field

[0001] This utility model relates to the field of packaging carton technology, specifically a pressure-resistant composite polymer heat-insulating, waterproof, and moisture-proof packaging carton. Background Technology

[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and they come in various sizes and models. Commonly used cardboard boxes have three or five layers, which can provide protection for goods.

[0003] In related technologies, a solution for a cardboard box with a heat preservation and freshness preservation structure (publication number CN222664154U) was found. This solution uses a waterproof layer that abuts against the surface of the cardboard box body and foam cardboard that slides on the inner wall of the cardboard box body to preserve and protect the inside of the cardboard box body, thereby extending the shelf life of the fresh food placed inside.

[0004] However, when the aforementioned cardboard boxes are sealed, a second clip is used to connect them to the foam cardboard to secure the connection between the foam cardboard and the cover. This sealing method allows the cover to be opened without damage, making it easy for the items inside the cardboard box to be replaced. After resealing, it is difficult to detect any traces, making it difficult to guarantee that the items are genuine and easily leading to disputes over authenticity. Utility Model Content

[0005] The purpose of this invention is to provide a pressure-resistant composite polymer thermal insulation, waterproof and moisture-proof packaging carton to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pressure-resistant composite polymer heat-insulating, waterproof, and moisture-proof packaging carton, including a box body, with a plastic film fitted over the lower part of the box body surface. When the box body is in a relatively humid environment, the plastic film can keep the box body dry. An insulation cover is fitted over the upper end of the box body, which can improve the sealing performance of the box body and provide good insulation.

[0007] A fixing frame is attached to the inner wall of the box, and a U-shaped buckle located on the outside of the box is connected to the fixing frame. The U-shaped buckle has two hooks.

[0008] A fixing piece is attached to the inner wall of the insulation cover. An insert piece located outside the insulation cover is connected to the fixing piece. The insert piece has an integrally formed cone head. When removing the insulation cover, the fixing piece needs to be torn off the insulation cover. At this time, the insulation cover is damaged, which makes it easier to determine whether it is the first time the box has been opened.

[0009] Two lifting straps are provided and connected to the bottom surface of the box. The lifting straps are sleeved on the surface of the heat preservation cover to facilitate lifting the box.

[0010] Furthermore, the surface of the heat-insulating cover is provided with an installation port, and a handling ring is provided inside the installation port, making it easier and less strenuous to move the box.

[0011] Furthermore, the inner wall of the heat-insulating cover is provided with four connecting pieces, and each connecting piece is provided with an integrally formed baffle. The lifting strap passes through the baffle and can restrain the lifting strap to bind the heat-insulating cover. When the box is lifted, the box and the heat-insulating cover are stably connected.

[0012] Furthermore, the upper inner wall of the heat-insulating cover is provided with a first support plate, and the bottom of the box is provided with a second support plate, which improves the compression resistance of the carton and provides better protection for the goods when the carton is stacked.

[0013] Furthermore, the side wall of the insulation cover is provided with a cotton ring, which is fitted onto the surface of the box to improve the sealing effect and enhance the heat insulation effect of the carton.

[0014] Furthermore, the surface of the heat insulation cover is provided with easy-tear holes around the fixing piece, which can easily tear the fixing piece off the heat insulation cover and create a tear that is difficult to repair.

[0015] Furthermore, the bottom surface of the box is provided with two anti-wear strips, which can reduce the wear of the plastic film, prevent the plastic film from tearing, and ensure the waterproof and moisture-proof function of the box.

[0016] Furthermore, the heat-insulating cover and the box body include two three-layer boards, and an aluminum foil is provided between the two three-layer boards to achieve aluminum foil protection. The multiple barrier structure effectively inhibits heat conduction and enhances heat insulation performance.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] (1) After the heat preservation cover is sealed to the box, the cone is inserted between the two hooks. At this time, the hooks lock the cone and cannot open the heat preservation cover, which prevents non-destructive opening. The fixing piece along with part of the heat preservation cover can be torn off through the easy-tear hole, causing damage to the heat preservation cover. This effectively prevents secondary packaging and product swapping, and can realize anti-counterfeiting protection of the product.

[0019] (2) The insulated lid and box body are made of three-layer board and aluminum foil, which not only enhances the overall strength of the carton, but also buffers the impact of external forces through the flexibility of the three-layer board, reducing the risk of damage during transportation. The aluminum foil layer can reflect heat radiation, and the carton has a good insulation effect. The plastic film protects the bottom of the box body, which can prevent the box body from getting damp and ensure that the box body is not easily damaged.

[0020] (3) The carton can be moved by two handling rings. The lifting strap has a limiting effect on the insulation cover after passing through the baffle. It is more convenient to lift the carton by using the lifting strap, providing different handling methods. Attached Figure Description

[0028] 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.

[0029] Example:

[0030] Please see Figure 1-6 This utility model provides a technical solution: a pressure-resistant composite polymer heat-insulating, waterproof, and moisture-proof packaging carton, including a box body 12. A plastic film 11 is fitted onto the lower part of the surface of the box body 12. The plastic film 11 can prevent the box body 12 from absorbing water, ensuring the structural strength of the box body 12 is stable and will not lose its protective function for the goods due to moisture. An insulation cover 1 is fitted onto the upper end of the box body 12. The insulation cover 1 can seal the box body 12, which can block air circulation and has a good insulation effect.

[0031] A fixing frame 20 is attached to the inner wall of the box body 12. A U-shaped buckle 7 located outside the box body 12 is connected to the fixing frame 20. The U-shaped buckle 7 has two hooks 10.

[0032] The fixing piece 19 is bonded to the inner wall of the heat insulation cover 1. The fixing piece 19 is connected to the insert piece 6 located outside the heat insulation cover 1. The insert piece 6 has an integrally formed cone head 13. The insert piece 6, cone head 13, fixing piece 19, U-shaped buckle 7, hook 10, and fixing frame 20 are injection molded, so the hook 10 is elastic, the cone head 13 can open the hook 10, and the fixing frame 20 is offset from the hook 10 so as not to affect the opening of the hook 10.

[0033] Lifting strap 2, two lifting straps 2 are provided and connected to the bottom surface of the box body 12. The lifting strap 2 is sleeved on the surface of the heat preservation cover 1. The lifting strap 2 is made of cloth strips, which makes it easy to lift the carton. The lifting strap 2 has a certain width to distribute the load pressure and can stably lift the carton.

[0034] In this embodiment, as Figure 1 and Figure 2 As shown, the surface of the heat insulation cover 1 is provided with an installation port 15, and the installation port 15 is provided with a transport ring 8. The transport ring 8 is made of polymer plastic (such as polypropylene or high-density polyethylene). The heat insulation cover 1 can be lifted by the transport ring 8. When the cone head 13 is engaged with the hook 10, the box body 12 can also be temporarily moved.

[0035] In this embodiment, as Figure 1 and Figure 4 As shown, the inner wall of the heat insulation cover 1 is provided with four connecting pieces 3. The heat insulation cover 1 has an outlet 4. The connecting piece 3 is provided with an integrally formed baffle 5. The baffle 5 is located on the surface of the heat insulation cover 1 through the outlet 4. The connecting piece 3 blocks the outlet 4. The lifting strap 2 passes through the baffle 5. When the lifting strap 2 is lifted, part of the lifting strap 2 is limited by the baffle 5, which plays a role in constricting the lifting strap 2.

[0036] In this embodiment, as Figure 4 As shown, the upper inner wall of the heat-insulating cover 1 is provided with a first support plate 17, and the bottom of the box body 12 is provided with a second support plate 18. The first support plate 17 and the second support plate 18 can be made of relatively stiff cardboard to improve the compression resistance of the carton. When the cartons are stacked, the bottom carton can be prevented from being crushed and the goods can be protected.

[0037] When the bottom of the product is uneven, the second support plate 18 can be made of polymer plastic. The second support plate 18 supports the product and prevents the box body 12 from being punctured due to excessive local stress.

[0038] In this embodiment, as Figure 4 As shown, the side wall of the heat insulation cover 1 is provided with a cotton ring 16. The cotton ring 16 is fitted onto the surface of the box body 12. The cotton ring 16 fills the gap between the heat insulation cover 1 and the box body 12, thereby eliminating the assembly tolerance gap between the heat insulation cover 1 and the box body 12, reducing heat loss from air convection, and enhancing the heat insulation capacity.

[0039] In this embodiment, as Figure 2 As shown, the surface of the heat insulation cover 1 is provided with easy-tear holes 9 around the fixing piece 19, which makes it easy to tear the fixing piece 19 from the heat insulation cover 1 and remove the fixing piece 19.

[0040] In this embodiment, as Figure 2 As shown, the bottom surface of the box body 12 is provided with two anti-wear strips 22. The thickness of the anti-wear strips 22 is greater than that of the baffle 5. When the cartons are stacked, the baffle 5 is prevented from damaging the insulation cover 1 below. The anti-wear strips 22 can prevent the plastic from being worn through and ensure that the plastic film 11 stably protects the box body 12.

[0041] In this embodiment, as Figure 6 As shown, the heat-insulating cover 1 and the box body 12 include two three-layer boards 21, and an aluminum foil 14 is provided between the two three-layer boards 21. The three-layer boards 21 can protect the aluminum foil 14, which can improve the structural strength of the carton and the heat-insulating effect. For some rounded products, the aluminum foil 14 will not be scratched. The position of the aluminum foil 14 can be moved to the inner wall of the box body 12.

[0042] Specifically, during use, when the product is placed in the box 12 and the insulation cover 1 is put on the box 12, the cone 13 is inserted between the two hooks 10. The cone 13 opens the hooks 10, ensuring that the hooks 10 stably hold the cone 13. The two three-layer boards 21 and aluminum foil 14 improve the heat preservation capacity of the box 12 and the insulation cover 1, effectively inhibiting the three heat loss methods of heat conduction, convection and radiation. The cotton ring 16 enhances the sealing between the box 12 and the insulation cover 1, resulting in good heat preservation effect.

[0043] The lifting strap 2 moves from the side of the baffle 5 to between the baffle 5 and the insulation cover 1. Two lifting straps 2 are used to easily lift the carton. Two handling rings 8 can also be used to temporarily move the carton and make it easier to stack the carton.

[0044] When opening the insulation cover 1, pry the insert 6 to move the fixing piece 19 along the easy-tear hole 9 to tear off part of the insulation cover 1. The insulation cover 1 can be moved up smoothly. The insulation cover 1 is damaged. If the insulation cover 1 is found to be torn before opening the box, it means that the insulation cover 1 has been opened. It can play a role in preventing the product from being counterfeited.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
