DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, purposes and effects achieved by the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0024] As Figure 1 - Figure 4 As shown in the figure, an anti-tear reinforced cushion foam box, the foam box has an inner cushion foam layer 1 and an outer cushion foam layer 2, wherein the inner cushion foam layer 1 is arranged inside the outer cushion foam layer 2, forming a unique structure.

[0025] Between the inner cushion foam layer 1 and the outer cushion foam layer 2, a clamping cavity is designed, and an anti-tear plastic layer 3 is arranged in the clamping cavity. The existence of the anti-tear plastic layer 3 significantly improves the anti-tear performance of the entire cushion foam box, making it more stable when subjected to external force impact.

[0026] The anti-tear plastic layer 3 is composed of an anti-tear bottom 31 and an anti-tear side 32, and the anti-tear bottom 31 is connected to the anti-tear side 32 around, together forming a box-shaped structure. Between the two adjacent anti-tear sides 32, a notch 33 is designed to facilitate the assembly and use of the foam box.

[0027] In order to further enhance the anti-tear performance, the anti-tear bottom 31 is respectively provided with a first extended anti-tear strip 34 at the upper and lower ends, and these anti-tear strips are integrally formed with the anti-tear bottom 31. Similarly, the anti-tear side 32 is also respectively provided with a second extended anti-tear strip 35 at the inner and outer ends, and these anti-tear strips are also integrally formed with the anti-tear side 32.

[0028] In order to ensure the close combination of the anti-tear plastic layer 3 and the inner cushion foam layer 1, a plurality of first embedding grooves 4 are formed on the outer wall of the inner cushion foam layer 1, and the first extended anti-tear strip 34 and the second extended anti-tear strip 35 can be embedded in these grooves. These anti-tear strips are connected with the inner cushion foam layer 1 through an adhesive, ensuring the stability and durability of the structure.

[0029] Similarly, to ensure the close combination of the tear-resistant plastic layer 3 and the outer cushion foam layer 2, a plurality of second embedding grooves 5 are also opened on the inner wall of the outer cushion foam layer 2, and the first and second extended tear-resistant strips 34 and 35 can also be embedded in these grooves. These tear-resistant strips are connected with the outer cushion foam layer 2 through adhesive, further enhancing the overall structural strength of the foam box.

[0030] The tear-resistant bottom 31, tear-resistant side 32, first and second extended tear-resistant strips 34 and 35 are all designed by one-piece molding, making the structure of the tear-resistant plastic layer 3 more solid. The material of the tear-resistant plastic layer 3 can be one or more of polyethylene, polypropylene, polyamide, and polyurethane, all of which have good tear-resistant properties.

[0031] Finally, the tear-resistant plastic layer 3 is connected with the inner and outer cushion foam layers 1 and 2 through adhesive, ensuring the stability and reliability of the entire cushion foam box during use.

[0032] According to design requirements, the inner and outer cushion foam layers 1 and 2 are prepared. These two layers of foam material are made through a specific foaming process, ensuring sufficient cushioning performance.

[0033] The tear-resistant plastic layer 3 is manufactured. The tear-resistant bottom 31 and tear-resistant side 32 are processed by one-piece molding process to ensure the structural solidity. Gaps 33 are designed between adjacent tear-resistant sides 32 to facilitate subsequent assembly. At the same time, the first and second extended tear-resistant strips 34 and 35 are integrally molded to ensure firm connection with the tear-resistant bottom 31 and tear-resistant side 32.

[0034] A plurality of first embedding grooves 4 are opened on the outer wall of the inner cushion foam layer 1, and a plurality of second embedding grooves 5 are opened on the inner wall of the outer cushion foam layer 2. These grooves are designed to accommodate tear-resistant strips, ensuring the close combination of the tear-resistant plastic layer 3 and the foam layer.

[0035] The tear-resistant plastic layer 3 is assembled with the inner and outer cushion foam layers 1 and 2. The first and second extended tear-resistant strips 34 and 35 are embedded in the first and second embedding grooves 4 and 5 respectively through adhesive, ensuring the stability and durability of the structure.

[0036] The entire cushion foam box is subjected to quality inspection to ensure that it meets design requirements and has sufficient tear-resistant and cushioning performance.

[0037] According to the needs, the items are placed inside the foam box. Due to the design of the inner and outer cushion foam layers 1 and 2, the items can be fully protected during transportation or storage.

[0038] When the foam box is subjected to external force tearing, the tear-resistant plastic layer 3 can effectively prevent the foam box from tearing. The presence of the first and second extended tear-resistant strips 34 and 35 further enhances the tear-resistant performance of the foam box, ensuring its stability during use.

[0039] When the foam box needs to be assembled or disassembled, the tear-resistant side 32 can be conveniently operated through the notch 33, achieving quick assembly or disassembly. This design makes the foam box more flexible and convenient during transportation, storage and use. The tear-resistant enhanced cushion foam box provides excellent tear-resistant performance and cushioning performance through its unique structure and material design, ensuring the safety and stability of the goods during transportation or storage.
