Abstract
Description
Technical Field
[0001] The utility model relates to the field of corrugated cardboard, and specifically relates to an antibacterial and insect-proof corrugated cardboard. Background Art
[0002] Corrugated cardboard is a multi-layer adhesive body, which is composed of at least one layer of corrugated core paper interlayer and one layer of cardboard. Generally, corrugated cardboard includes an inner paper layer, core paper, and an outer paper layer. The core paper is clamped between the inner paper layer and the outer paper layer. It has high mechanical strength and can withstand collisions and drops during handling.
[0003] At present, most corrugated cardboard has the characteristics of antibacterial and insect-proof. Antibacterial coatings and insect-proof coatings are set on the inner side of the cardboard. However, the insect-proof coating is essentially an insecticide. After the insecticide is sprayed on the corrugated cardboard for a period of time, it volatilizes and dries, and the insect-proof effect is greatly reduced. Therefore, it is necessary to design an antibacterial and impact-proof corrugated cardboard to achieve the purpose of long-term insect prevention. Content of the Utility Model
[0004] Based on this, the purpose of the utility model is to provide an antibacterial and insect-proof corrugated cardboard to solve the technical problem that the insect-proof effect is greatly reduced after the insecticide is sprayed on the corrugated cardboard for a period of time and volatilizes and dries.
[0005] To achieve the above purpose, the utility model provides the following technical solution: an antibacterial and insect-proof corrugated cardboard, including a cardboard main body. The cardboard main body includes two outer cardboard layers. An gourd film is pasted on the inner side of the outer cardboard layer. A number of cavities are formed inside the gourd film. Insecticide is injected into the cavities. Micropores are formed on the surface of the gourd film.
[0006] By adopting the above technical solution, insecticide is injected into the cavities of the gourd film and slowly released through the micropores, providing a long-term insect prevention solution. This avoids the problem of weakening over time in the traditional method of applying or spraying insecticide, ensuring that the corrugated cardboard continuously maintains the insect-proof effect during use.
[0007] Further, an antibacterial cardboard is pasted on the inner side of the gourd film, and a paper core board is pasted on the inner side of the antibacterial cardboard.
[0008] By adopting the above technical solution, the antibacterial cardboard has the ability to inhibit or kill bacteria, which provides an additional protective layer for the corrugated cardboard, helps to maintain the hygiene of the packaged contents, and prevents contamination caused by bacteria.
[0009] Further, the paper core board is corrugated, and the corrugated paper core board is used to enhance the compressive performance of the cardboard main body.
[0010] By adopting the above technical solution, the corrugated paper core board in a wave shape can disperse pressure, increase the overall strength of the corrugated cardboard, and enable the cardboard body to better withstand external forces, such as the oppression of heavy objects or impacts during transportation.
[0011] Furthermore, several of the cavities are evenly arranged on the gourd film, and micropores are opened on the gourd film of each cavity.
[0012] By adopting the above technical solution, the even arrangement of the cavities ensures that the insecticide can be evenly released throughout the corrugated cardboard, providing comprehensive insect protection and avoiding the problem of insufficient protection in local areas.
[0013] Furthermore, the thickness of the antibacterial cardboard is less than that of the outer cardboard, and an antibacterial coating is applied on the surface of the antibacterial cardboard.
[0014] By adopting the above technical solution, the antibacterial coating can effectively inhibit or kill the growth of microorganisms such as bacteria and molds, providing more comprehensive protection to ensure the hygienic safety of the packaged contents. The smaller thickness of the antibacterial cardboard helps to reduce the material cost while not sacrificing the overall performance and protection ability of the corrugated cardboard.
[0015] Furthermore, there are two of the outer cardboard, gourd film, and antibacterial cardboard. The two outer cardboard, gourd film, and antibacterial cardboard are mirror-symmetrically arranged with the paper core board as the center, and the outer cardboard, gourd film, and antibacterial cardboard are arranged in sequence from the outside to the inside.
[0016] By adopting the above technical solution, with two symmetrically arranged outer cardboard, gourd film, and antibacterial cardboard, the overall structural strength of the corrugated cardboard is significantly improved, better resisting external pressure and impact.
[0017] In summary, the present utility model mainly has the following beneficial effects:
[0018] 1. By setting the gourd film in the present utility model, an insecticide is injected into the cavities inside the gourd film. Each cavity of the gourd film corresponds to a micropore. During long-term use, the insecticide in the cardboard can slowly volatilize, achieving a certain insect control effect and avoiding being eaten by insects. The insecticide is a pyrethroid compound, which improves the service life of the cardboard body and extends the insect control time.
[0019] 2. By setting the gourd film in the present utility model, the gourd film is an inflated film processed from polyethylene as the raw material. The gourd film not only has the same advantages but also is an environmentally friendly material that can be recycled, and can improve the compressive and buffering effects of the cardboard body.

[0024] 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. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.
[0025] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.
[0026] Embodiment 1:
[0027] An antibacterial and insect-proof corrugated cardboard, as Figures 1-3 shown, includes a cardboard main body 1. The cardboard main body 1 includes two outer cardboards 2. A gourd film 3 is pasted on the inner side of the outer cardboard 2. A number of cavities are formed inside the gourd film 3, and pesticides are injected into the cavities. Micropores 31 are formed on the surface of the gourd film 3. The pesticides are injected into the cavities of the gourd film 3 and slowly released through the micropores 31, providing a long-term insect-proof solution. This avoids the problem of weakening over time in the traditional methods of smearing or spraying pesticides, ensuring that the corrugated cardboard continuously maintains an insect-proof effect during use. The structural design of the corrugated cardboard enhances the overall stability and pressure resistance by using two outer cardboards 2 and pasting a gourd film 3 on the inner side. This structure helps to protect the packaged items from being affected by collisions and pressures during transportation.
[0028] Please refer to Figure 2 , a waterproof layer is pasted on the outer side of the outer cardboard 2 to improve the waterproof performance of the cardboard main body 1.
[0029] Please refer to Figure 2, an antibacterial cardboard 4 is pasted on the inner side of the gourd film 3, and a paper core board 5 is pasted on the inner side of the antibacterial cardboard 4. The antibacterial cardboard 4 has the ability to inhibit or kill bacteria, which provides an additional protective layer for the corrugated cardboard, helps maintain the hygiene of the packaged contents and prevent contamination caused by bacteria. The paper core board 5 is usually wavy, and this structure enhances the overall compressive strength and buffering performance of the corrugated cardboard, helping to protect the goods from impact and pressure damage during transportation. Since the corrugated cardboard is mainly made of paper materials, these materials are recyclable and biodegradable, meeting the requirements of sustainable development.
[0030] Please refer to Figure 2 , the paper core board 5 is wavy. The wavy paper core board 5 is used to enhance the compressive performance of the cardboard body 1. The wavy paper core board 5 can disperse pressure, increase the overall strength of the corrugated cardboard, and make the cardboard body 1 more capable of withstanding external forces such as heavy object pressure or impact during transportation. The wavy shape provides a good buffering effect, helping to absorb and slow down the impact force, thus protecting the contents inside from damage. Due to its structural characteristics, the wavy paper core board 5 can provide the same or even higher strength and protection while using less material.
[0031] Please refer to Figure 3 , a number of cavities are evenly arranged on the gourd film 3, and micropores are opened on the gourd film of each cavity. The even arrangement of the cavities ensures that the insecticide can be evenly released throughout the corrugated cardboard, providing comprehensive insect protection and avoiding the problem of insufficient protection in local areas. By controlling the release rate of the insecticide through the micropores, a long-term and stable insect protection effect can be achieved, reducing the weakening of protection caused by the passage of time. The evenly arranged cavities mean that the use of the insecticide is more efficient, and each cavity is fully utilized without waste, thus reducing the overall cost.
[0032] Example two:
[0033] Please refer to Figure 2 , the thickness of the antibacterial cardboard 4 is less than the thickness of the outer cardboard 2. The surface of the antibacterial cardboard 4 is coated with an antibacterial coating. The antibacterial coating can effectively inhibit or kill the growth of microorganisms such as bacteria and molds, providing more comprehensive protection and ensuring the hygienic safety of the packaged contents. The smaller thickness of the antibacterial cardboard 4 helps to reduce the material cost, while not sacrificing the overall performance and protection ability of the corrugated cardboard. The thinner antibacterial cardboard 4 can speed up the process of coating the antibacterial coating, improving the efficiency and output of the production line.
[0034] Please refer to Figure 2, there are two outer cardboard sheets 2, gourd membranes 3, and antibacterial cardboard sheets 4. The two outer cardboard sheets 2, gourd membranes 3, and antibacterial cardboard sheets 4 are mirror - set with the paper core board 5 as the center. The outer cardboard sheets 2, gourd membranes 3, and antibacterial cardboard sheets 4 are arranged in sequence from the outside to the inside. For the two symmetrically - set outer cardboard sheets 2, gourd membranes 3, and antibacterial cardboard sheets, the overall structural strength of the corrugated cardboard is significantly improved, better resisting external pressure and impact, ensuring the uniform distribution of the insecticide and antibacterial agent in the cardboard, and providing comprehensive and balanced insect - proof and antibacterial protection.
[0035] The implementation principle of this embodiment is as follows: A gourd membrane 3 is arranged on the inner side of the outer cardboard sheet 2, and an insect - proof agent is injected into the cavity inside the gourd membrane 3. Each cavity of the gourd membrane 3 corresponds to a micropore 31. During long - term use, the insect - proof agent in the cardboard can slowly volatilize, achieving a certain insect - prevention effect and preventing the cardboard main body 1 from being eaten by insects. The insect - proof agent is a pyrethroid compound, which improves the service life of the cardboard main body 1 and extends the insect - prevention time. The gourd membrane 3 is an environmentally friendly material and can be recycled, which can improve the compressive and buffering effects of the cardboard main body 1.
