Description

Technical Field

[0001] This utility model relates to the field of foam box technology, and in particular to a high-strength integrated foam box. Background Technology

[0002] In diverse fields such as logistics and transportation, warehousing, protection of precision parts, fresh food cold chain distribution, and e-commerce packaging, foam boxes have become one of the most widely used and frequently used packaging and storage containers due to their unique performance advantages. Among these, lightweight, low cost, and certain cushioning performance are the three core characteristics that make them stand out from many packaging materials and become the preferred solution for different industry scenarios.

[0003] Existing foam boxes have weak impact and tensile strength. If they are subjected to collisions or squeezing during transportation, or are subjected to the pressure of heavy items during storage, they are prone to cracking, denting, and deformation. Furthermore, existing foam boxes rely solely on the elasticity of their own materials, with smooth side walls and no reinforced bottom structure, making it easy for impact energy to concentrate and difficult to protect delicate and fragile items. Utility Model Content

[0004] In view of the existing technology, the existing foam boxes have weak impact and tensile strength. If they are subjected to collisions, squeezing, or heavy items during transportation, they are prone to cracking, denting, and deformation. In addition, the existing foam boxes rely only on the elasticity of the material itself, with smooth side walls and no reinforced bottom structure, making it easy for impact energy to concentrate and difficult to protect delicate and fragile items. This utility model provides a high-strength integrated foam box.

[0005] The technical solution adopted in this utility model is as follows: a high-strength integrated foam box, comprising a box body and a box lid, both of which are integrally molded from high-density EPP material. The outer side of the box body is wrapped with a glass fiber reinforced mesh, which is fixedly connected to the box body by epoxy resin and covers the outer wall of the box body. The bottom of the box lid has two symmetrical positioning plates integrally molded. The top of the box body has positioning grooves that fit into the two positioning plates. The box lid is connected to the box body by being inserted into the positioning grooves through the positioning plates. The high-density EPP material is lightweight. The overall weight of the foam box is significantly reduced, making it easier to handle and transport, reducing labor and logistics costs. The one-piece molding process avoids splicing gaps, improves structural integrity, enhances the impact and deformation resistance of the box body and lid, and extends service life. The glass fiber reinforced mesh itself has the characteristics of high strength and high toughness, which can form "double protection" with high-density EPP material, significantly improving the tensile and compressive resistance of the outer wall of the box, effectively preventing the box from cracking or denting due to collision or heavy pressure during transportation and stacking, ensuring the safety of the contents. The matching design of the positioning plate and positioning groove can quickly achieve precise positioning of the lid and box body.

[0006] Furthermore, both sides of the two positioning plates are provided with multiple anti-slip ridges arranged in a linear array. The anti-slip ridges can increase the contact friction between the positioning plate and the inner wall of the positioning groove, effectively resist the vibration and impact during transportation and handling, prevent the lid from loosening due to vibration, ensure that the lid is always tightly fitted to the box body, and ensure that the internal items will not shake or collide due to the lid being loose.

[0007] Furthermore, the upper surface of the box lid is provided with multiple protruding plates arranged in a linear array, and all of the protruding plates are integrally formed with the box lid. The bottom of the box body is provided with multiple limiting grooves that fit with the protruding plates. The fitting structure of the protruding plates and limiting grooves can achieve precise positioning when multiple foam boxes are stacked. The limiting groove at the bottom of the upper foam box can quickly engage with the protruding plate of the lower foam box lid, preventing the foam boxes from shifting laterally during the stacking process and improving the convenience and efficiency of the stacking operation.

[0008] Furthermore, the inner wall of the enclosure is bonded with an EVA buffer layer, and the surface of the EVA buffer layer is provided with a wavy buffer texture. EVA material itself has excellent elasticity and shock absorption properties, which can effectively absorb the force of external impact on the internal items and prevent the items from being damaged by impact. The wavy buffer texture can further disperse the impact energy and the pressure of the items, so that the pressure is evenly distributed on the surface of the buffer layer, avoiding excessive local pressure that could cause the items to deform or be damaged. This provides all-round side wall protection for the internal items and improves the safety of the stored items.

[0009] Furthermore, a reinforcing plate is provided at the bottom of the box, and the reinforcing plate is made of modified PP material. The reinforcing plate is tightly attached to the inner wall of the bottom of the box and fixedly connected by hot melt adhesive. The modified PP material has the characteristics of high strength and high rigidity, which can significantly enhance the load-bearing limit of the bottom of the box and prevent the bottom of the box from sinking or deforming due to the large weight of the items inside the box, thus ensuring the structural integrity of the box. The hot melt adhesive connection method has the characteristics of high bonding strength and good sealing performance, which can ensure that the reinforcing plate does not loosen or shift during long-term use.

[0010] Furthermore, grooves are provided on both sides of the box, and first handle slots are provided on the inner walls of the two grooves. The grooves provide a reasonable grip space for the hands, and the operator can naturally put their hands into the grooves when carrying the box, avoiding direct friction between the hands and the outer wall of the box, and reducing hand discomfort during the carrying process. The first handle slots facilitate stable gripping of the box and reduce the risk of the box slipping during carrying.

[0011] Furthermore, an identification tag is affixed to the surface of the groove on one side. The tag can indicate key information such as the name, specifications, storage number, and storage date of the items inside the box. Operators can quickly identify the items inside the box without opening the lid, which greatly improves the efficiency of warehouse sorting and retrieval. In addition, the groove can prevent the tag from directly rubbing or colliding with external objects during handling and stacking, effectively preventing the tag from wearing off, falling off, or becoming blurred, ensuring that the tag is clear and identifiable for a long time and reducing the cost of repeated labeling.

[0012] Furthermore, a second handle groove is provided on both sides of the lid, allowing fingers to be inserted into the second handle groove and the lid to be easily lifted upwards using the force points of the handle groove. This avoids slipping when opening due to the smooth surface of the lid, and is especially suitable for scenarios where the lid and the box body are tightly connected, reducing the difficulty of opening.

[0013] The beneficial effects of this utility model are: 1. This utility model uses high-density EPP material to integrally mold the box body and lid, and combines it with glass fiber reinforcement mesh on the outside of the box body, which greatly enhances the impact resistance and tensile strength, avoids cracking and deformation, and solves the problem that the existing foam boxes have weak impact resistance and tensile strength, and are prone to cracking, denting and deformation if they are hit by collisions or squeezing during transportation, or are subjected to the pressure of heavy items during storage.

[0014] 2. This utility model forms a synergistic protection through the EVA buffer layer on the inside of the box and the modified PP reinforcing plate on the bottom, which can disperse impact energy, improve load-bearing capacity, and effectively protect delicate and fragile items. It solves the problem that existing foam boxes rely solely on their own material elasticity, have smooth side walls and no reinforced bottom structure, making it easy for impact energy to concentrate and difficult to protect delicate and fragile items.

[0019] The following is in conjunction with the appendix Figures 1-4 The present invention will be further described below.

[0020] To address the problems existing in the background technology, this application proposes the following technical solution: a high-strength integrated foam box.

[0021] The specific technical solution includes a box body 1 and a box cover 2. Both the box body 1 and the box cover 2 are integrally molded from high-density EPP material. The outer side of the box body 1 is wrapped with a glass fiber reinforced mesh 3, which is fixedly connected to the box body 1 with epoxy resin and covers the outer wall of the box body 1. The bottom of the box cover 2 has two symmetrical positioning plates 4 integrally molded. The top of the box body 1 has positioning grooves 5 that fit with the two positioning plates 4. The box cover 2 is connected to the box body 1 by inserting the positioning plates 4 into the positioning grooves 5. The connection between the box cover 2 and the box body 1 achieves precise positioning and stable assembly through the "positioning plate 4-positioning groove 5" structure. The two symmetrical positioning plates 4 integrally molded at the bottom of the box cover 2 can be directly inserted into the fitting positioning grooves 5 opened at the top of the box body 1. This structure can quickly determine the relative position of the box cover 2 and the box body 1, avoiding misalignment when closing.

[0022] Reference Figure 1 and Figure 2 As shown, both sides of the two positioning plates 4 are provided with multiple anti-slip ridges 6 arranged in a linear array. The anti-slip ridges 6 can increase the friction between the positioning plate 4 and the inner wall of the positioning groove 5, effectively preventing the lid 2 from loosening due to vibration during transportation and handling, further improving the stability after the lid is closed, and ensuring the sealing and safety of the overall structure of the box 1.

[0023] Reference Figure 1 , Figure 2 and Figure 4As shown, the upper surface of the box cover 2 is provided with multiple protruding plates 7 arranged in a linear array. The multiple protruding plates 7 are integrally formed with the box cover 2. The bottom of the box body 1 is provided with multiple limiting grooves 8 that fit with the protruding plates 7. The multiple linear array protruding plates 7 integrally formed on the upper surface of the box cover 2 correspond to the fitting limiting grooves 8 opened at the bottom of the box body 1 to prevent the foam box from sliding during stacking, and at the same time ensure the verticality after stacking to prevent tipping.

[0024] Reference Figures 1 to 3 As shown, an EVA buffer layer 9 is bonded to the inner wall of the box 1, and the surface of the EVA buffer layer 9 has a wavy buffer texture. A reinforcing plate 10 is provided at the bottom of the box 1, and the reinforcing plate 10 is made of modified PP material. The reinforcing plate 10 is tightly attached to the inner wall of the bottom of the box 1 and is fixedly connected by hot melt adhesive. The good elasticity and shock absorption performance of the EVA material itself can absorb the force of external impact on the internal items. At the same time, the wavy buffer texture on the surface of the EVA buffer layer 9 can further disperse the impact energy, reduce local pressure, and prevent items from being damaged by collision. The high strength of the modified PP material enhances the load-bearing capacity of the bottom of the box 1 and prevents the bottom of the box 1 from deforming due to the weight of the items. The reinforcing plate 10 and the EVA buffer layer 9 form a synergistic protection, providing all-round buffer protection for the internal items from the bottom and side wall dimensions, which is suitable for the storage needs of various fragile and delicate items.

[0025] Reference Figures 1 to 4 As shown, grooves 11 are provided on both sides of the box body 1, and first handle grooves 12 are provided on the inner walls of the two grooves 11 respectively. A label 13 is affixed to the surface of one side of the groove 11. Second handle grooves 14 are provided on both sides of the box cover 2. The first handle grooves 12 facilitate the handling of the box body 1, and the second handle grooves 14 facilitate the opening of the box cover 2. The label 13 can be used to mark the information of the items inside the box body 1, storage number, etc., so that the operator can quickly identify the items inside the box. It is also set in the groove 11 to avoid external friction.

[0026] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview: Slowly place the items to be stored into the box 1, ensuring that the items are in full contact with the EVA buffer layer 9. The elasticity and wavy texture of the EVA material will disperse the pressure of the items, while avoiding direct impact of the items on the inner wall of the box 1 or the reinforcing plate 10 to prevent damage. Align the two positioning plates 4 at the bottom of the box lid 2 with the positioning grooves 5 at the top of the box 1, and slowly insert the positioning plates 4 into the positioning grooves 5 until the box lid 2 and the edge of the box 1 are in contact. During the process, the positioning plate 4 and the positioning groove 5 are matched to quickly calibrate the position of the box cover 2 and avoid displacement. At the same time, the anti-slip ridges 6 on both sides of the positioning plate 4 will rub against the inner wall of the positioning groove 5 to ensure that the box cover 2 is not loose after closing and to ensure the sealing of the box body 1. The operator can reach into the first handle groove 12 in the groove 11 on both sides of the box body 1 and slowly lift and move it. When it is necessary to store in batches, first place the bottom device stably on the horizontal ground, then take the upper device, align it with the limiting groove 8 at the bottom of the box body 1 and the convex plate 7 on the upper surface of the box cover 2 of the lower device, and slowly lower the upper device so that the limiting groove 8 is accurately engaged with the convex plate 7. After engagement, confirm that the upper device does not slide laterally. The cooperation between the convex plate 7 and the limiting groove 8 ensures the verticality of the stack and prevents it from tipping over.
