DETAILED DESCRIPTION
[0017] The following will be combined with the drawings Figs. 1 to 3 Detailed description of the utility model.
[0018] The utility model discloses a novel compression -resistant carton with multilayer composite structure, including carton body 1, the carton body 1 includes top plate 2, bottom plate 3 and at least four side plates 4, the four side plates 4 are connected in sequence and form the cavity 5 for placing articles, the top plate 2 is set to the top surface of cavity 5, and the bottom plate 3 is set to the bottom surface of cavity 5, as Fig. 3 The utility model discloses a novel compression -resistant carton with multilayer composite structure, including carton body 1, the carton body 1 includes top plate 2, bottom plate 3 and at least four side plates 4, the four side plates 4 are connected in sequence and form the cavity 5 for placing articles, the top plate 2 is set to the top surface of cavity 5, and the bottom plate 3 is set to the bottom surface of cavity 5, as
[0019] The utility model improves the existing carton structure, changes the paperboard into multilayer composite structure, thereby enhancing the compression resistance of the formed carton, reducing the damage of valuable articles due to logistics, and reducing the loss; on the other hand, the service life of the carton is prolonged, the carton can be recycled and reused, and the cost of using the carton is more favorable. Meanwhile, the carton is provided with a second buffer layer 31 at the bottom, the second buffer layer 31 cooperates with the first buffer layer 7 to play a double-layer buffering role, the external force is better buffered to protect the goods, and the second buffer layer 31 further comprises an elastic support body 32, the elastic support body 32 can be formed by using a soft material such as silica gel and is symmetrically distributed on the upper surface of the second buffer layer 31, since the elastic support body 32 is elastic, the elastic support body 32 can also play a role in buffering external force, and the elastic support body 32 is usually four, and is distributed at the four corners of the bottom plate 3. The second buffer layer 31 of the utility model can be assembled according to actual conditions, for example, if the second buffer layer 31 is not needed, the second buffer layer 31 can be removed.
[0020] As an embodiment, the outer compression-resistant layer 6 is high-density corrugated paper, and the thickness D1 of the outer compression-resistant layer 6 is greater than or equal to 5 mm. The corrugated paperboard with the thickness forms a hard shell of the carton and is the main source of the compression resistance of the carton.
[0021] As another embodiment, the first buffer layer 7 is a honeycomb polyethylene foam core material, and the porosity of the first buffer layer 7 is 40%-50%. The material layer with the specification enhances the inner layer buffer of the paperboard and strengthens the strength of the paperboard.
[0022] As still another embodiment, the inner compression-resistant layer 8 is a degradable plant fiber layer. The structural layer cooperates with the outer compression-resistant layer 6 to position the first buffer layer 7, and the inner compression-resistant layer 8 has a certain strength and cooperates with the outer compression-resistant layer 6 and the first buffer layer 7 to improve the compression resistance of the carton. The structural layer of the material also has environmental protection performance and is easy to degrade.

After the articles are placed in the carton, the pressing plane 42 contacts the surface of the articles, positions and protects the articles, and prevents the upper end of the articles from shaking in the carton.
[0024] On the basis of the above structure, in order to further improve the technical scheme, the pressing plane 42 is embedded with a magnet 43. The magnet 43 faces the articles, and can interact with the articles with metal shells to generate an attractive force, thereby better positioning the articles,
[0025] The above content is only a preferred embodiment of the utility model, and for ordinary skilled persons in the art, the specific implementation manner and application range can be changed according to the thought of the utility model, and the content of the specification should not be understood as a limitation of the utility model.
