Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard box technology, and in particular to a moisture-proof corrugated cardboard box. Background Technology

[0002] Corrugated cardboard boxes are one of the most widely used packaging products, and their usage has always been the highest among all packaging products. For more than half a century, corrugated cardboard boxes have gradually replaced wooden boxes and other transport packaging containers due to their superior performance and good processing performance, becoming the mainstay of transport packaging. In addition to protecting goods and facilitating warehousing and transportation, they also play a role in beautifying and promoting goods.

[0003] Traditional corrugated cardboard boxes have poor moisture resistance. In humid environments, the boxes easily absorb moisture, causing them to soften and lose strength. This not only fails to effectively protect the contents but may also damage them due to moisture, rendering them ineffective as packaging. Furthermore, once the boxes become damp, the contents are also susceptible to moisture damage, leading to mold, spoilage, and other problems, posing risks to the quality and safety of the goods. Utility Model Content

[0004] In order to overcome the shortcomings of poor moisture-proof performance of corrugated cardboard boxes, this utility model provides a moisture-proof corrugated cardboard box.

[0005] The technical solution is as follows: A moisture-proof corrugated cardboard box includes a box body, a lid, a waterproof membrane, a drying layer, and a corrugated cardboard layer. The lid is located on the upper side of the box body, and multiple drainage holes are located on the side of the box body. The box body is composed of a waterproof membrane, a drying layer, and a corrugated cardboard layer, arranged from the outside to the inside. That is, the waterproof membrane is in contact with the outside, the waterproof membrane completely wraps the drying layer, and the drying layer completely wraps the corrugated cardboard layer. At the drainage holes, the box body structure is also such that the waterproof membrane is on the outermost layer and the corrugated cardboard layer is on the innermost layer.

[0006] As an improvement to the above solution, the drainage holes are evenly distributed at the bottom of the side of the box.

[0007] As an improvement to the above solution, a reinforcing layer is also included, with a reinforcing layer provided between the drying layer and the corrugated paper layer on one side.

[0008] As an improvement to the above solution, the reinforcing layer is made of kraft paper, honeycomb paper, or a plastic mesh structure.

[0009] As an improvement to the above solution, it also includes vertical and horizontal plates. There are 8 vertical plates at the four corners inside the box, and two adjacent vertical plates are connected to each other. There are 4 horizontal plates on the inner side wall and bottom of the box, and the two ends of the horizontal plates are connected to the adjacent vertical plates. The angle between the horizontal plates and the vertical plates is 90 degrees.

[0010] As an improvement to the above solution, it also includes reinforcing plates. Multiple reinforcing plates are provided on the inner side wall of the box. The reinforcing plates are right-angled triangles, and their two right-angled sides are connected to the vertical plate and the horizontal plate, respectively.

[0011] As an improvement to the above solution, the waterproof membrane is a polyethylene (PE) or polypropylene (PP) film.

[0012] As an improvement to the above solution, the drying layer is made of silica gel, absorbent paper, or mineral desiccant.

[0013] The beneficial effects of this utility model are: 1. Through the design of the waterproof membrane and drying layer on the box, this utility model can effectively block rainwater, moisture or liquid penetration, prevent water from damaging the corrugated paper layer from the source, and protect the carton structure from moisture damage; through the design of the drainage hole, the accumulated water can be discharged from the drainage hole, and the water will not seep in from the drainage hole, effectively avoiding the accumulation of water in the box, which may cause the carton to deform or the goods to be damaged.

[0014] 2. This utility model, by setting a reinforcing layer between the drying layer and the corrugated paper layer, can compensate for the problem of weakened strength of the corrugated paper layer due to moisture, ensuring that the carton maintains stable performance in a humid environment. Through the design of vertical plates, horizontal plates and reinforcing plates, the internal structure of the carton is further strengthened, the overall stability of the carton is enhanced, and it helps to disperse external forces and prevent the carton from being damaged due to excessive local stress.

[0019] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0020] A type of moisture-proof corrugated cardboard box, such as Figures 1-3As shown, the box includes a box body 1, a box lid 2, a waterproof membrane 4, a drying layer 5, and a corrugated cardboard layer 6. The box body 1 has a box lid 2 on its upper side, and multiple drainage holes 3 are provided on the four sides of the box body 1. The box body 1 is composed of a waterproof membrane 4, a drying layer 5, and a corrugated cardboard layer 6. From the outside to the inside, the waterproof membrane 4 is in contact with the outside, the waterproof membrane 4 completely wraps the drying layer 5 to isolate moisture, and the drying layer 5 completely wraps the corrugated cardboard layer 6 to absorb moisture that passes through the waterproof membrane 4. At the drainage holes 3, the structure of the box body 1 is also such that the waterproof membrane 4 is on the outermost layer and the corrugated cardboard layer 6 is on the innermost layer.

[0021] The waterproof membrane 4 on the outside of the box 1 is in direct contact with the external environment, effectively blocking rainwater, moisture or liquid penetration and preventing moisture from damaging the corrugated cardboard layer 6. The drying layer 5 is sandwiched between the waterproof membrane 4 and the corrugated cardboard layer 6. It uses moisture-absorbing material to continuously absorb moisture generated inside and outside the box 1 due to the humid environment or the contents, maintaining a dry internal environment. When water accidentally enters the box 1 or the contents leak, the water can be discharged from the drain hole 3, preventing moisture from accumulating inside the box and causing the carton to deform or the goods to be damaged. At the same time, the structural design of the drain hole 3 (the waterproof membrane 4 is on the outer layer and the corrugated cardboard layer 6 is on the inner layer) ensures that water will not seep in from the drain hole 3.

[0022] Drainage holes 3 are evenly distributed at the bottom of the side of the box 1. When water accidentally enters the box 1 or the contents leak, the water can be discharged more smoothly and quickly through the drainage holes 3, avoiding water accumulation inside the box and thus effectively preventing the carton from deforming or the goods from being damaged due to water accumulation.

[0023] like Figures 1-2 As shown, it also includes a reinforcing layer 7. The reinforcing layer 7 is provided between the drying layer 5 on one side and the corrugated paper layer 6. The reinforcing layer 7 can compensate for the weakening of the strength of the corrugated paper layer 6 due to moisture, and ensure that the carton maintains stable performance in a humid environment.

[0024] The reinforcing layer 7 is made of kraft paper, honeycomb paper, or plastic mesh structure. These materials have certain strength and stability, and appropriate materials can be selected according to actual needs to enhance the performance of the carton.

[0025] like Figure 1 and Figure 3 As shown, it also includes vertical plates 8 and horizontal plates 9. There are 8 vertical plates 8 at the four corners inside the box body 1. Two adjacent vertical plates 8 are connected to each other. There are 4 horizontal plates 9 on the inner side wall and bottom of the box body 1. The two ends of the horizontal plates 9 are connected to the adjacent vertical plates 8. The angle between the horizontal plates 9 and the vertical plates 8 is 90 degrees. The vertical plates 8 and the horizontal plates 9 cooperate to form a stable frame structure, which further enhances the structural strength of the box body 1, making the carton less prone to deformation when subjected to external forces, and providing more reliable protection for the internal goods.

[0026] like Figure 1 and Figure 3As shown, it also includes a reinforcing plate 10. Multiple reinforcing plates 10 are provided on the inner side wall of the box body 1. The reinforcing plate 10 is a right triangle, and its two right-angled sides are connected to the vertical plate 8 and the horizontal plate 9 respectively, which further strengthens the internal structure of the box body 1, enhances the overall stability of the carton, helps to disperse external forces, and prevents the carton from being damaged due to excessive local stress.

[0027] The waterproof membrane 4 is a polyethylene (PE) or polypropylene (PP) film. These materials have good waterproof performance and can effectively block rainwater, moisture or liquid penetration, and prevent moisture from damaging the corrugated paper layer 6.

[0028] The drying layer 5 is made of silica gel, absorbent paper, or mineral desiccant. These materials have moisture-absorbing properties and can continuously absorb moisture from the inside and outside of the box 1 caused by environmental humidity or the contents, maintaining a dry internal environment.

[0029] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
