[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0032] Please refer to Figures 1 - 4 , the present utility model provides the following technical solutions: An impact-resistant packaging container, including a main body of the packaging container 1, and the main body of the packaging container 1 includes: an outer layer of the container 11 and an inner layer of the container 12.

[0033] Further, as shown by Figure 1 , Figure 2 and Figure 4 in this embodiment, the outer layer 11 of the container is one of PP, HDPE, PPC or PC. An inner concave portion 111 is provided on the outer layer 11 of the container for forming an outer reinforcing rib 114. The inner layer 12 of the container is located inside the outer layer 11 of the container. The inner layer 12 of the container is one of PC, PE, PP, PET or PS. An inner reinforcing rib 121 is provided on the outer wall of the inner layer 12 of the container. After adopting the above solution, during use, the outer layer 11 of the container and the inner layer 12 of the container are combined into the packaging container body 1. The inner layer 12 of the container adopts a food-safe material and can be in direct safe contact with food. The outer layer 11 of the container adopts a high-strength and wear-resistant plastic and has good impact resistance, which can effectively reduce the risk of container breakage during transportation and handling, ensuring the safety of food during storage, transportation and handling. Moreover, the outer layer 11 and the inner layer 12 of the container are respectively provided with an outer reinforcing rib 114 and an inner reinforcing rib 121, further improving the structural strength of the outer layer 11 and the inner layer 12 of the container, and not easily deforming and being damaged by extrusion, not only ensuring the safety of the packaging container body 1, but also ensuring the safety of the internal food.

[0034] Optionally, as shown by Figure 1 and Figure 2 in this embodiment, the outer layer 11 of the container is PPC, that is, polypropylene polycarbonate. Polypropylene polycarbonate has good physical, mechanical and thermal properties, has good stiffness and toughness, high impact resistance, and can maintain stable performance in harsh environments. At the same time, polypropylene polycarbonate also has a relatively high heat distortion temperature, chemical resistance and load-bearing capacity.

[0035] Optionally, as shown by Figure 1 and Figure 2 in this embodiment, the inner layer 12 of the container is PP, that is, polypropylene, which is often used to make food packaging materials. The food packaging materials made of polypropylene material have high strength and rigidity, and at the same time have good impact resistance. At the same time, the polypropylene material is non-toxic and harmless and can be used at high temperatures without generating harmful substances in a high-temperature environment. Therefore, the food packaged by the polypropylene material can be directly heated in a microwave oven. In addition, the polypropylene material also has excellent barrier properties and can effectively prevent oxygen, moisture and other external factors from invading the food, maintaining the freshness and taste of the food.

[0036] Preferably, as shown by Figure 1 , Figure 2 and Figure 4As shown, in this embodiment, the outer layer 11 of the container is a circular member, and a plurality of concave portions 111 are evenly distributed along the circumferential direction. There is a limiting groove 115 between two adjacent outer reinforcing ribs 114, which improves the structural strength and impact resistance of the outer layer 11 of the container.

[0037] Preferably, Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the inner layer 12 of the container is a circular member, and a plurality of inner reinforcing ribs 121 are evenly distributed along the circumferential direction. The inner reinforcing ribs 121 are embedded in the limiting grooves 115, which improves the structural strength and impact resistance of the inner layer 12 of the container, and at the same time improves the connection stability between the inner layer 12 of the container and the outer layer 11 of the container.

[0038] Preferably, Figures 1 - 3 As shown, in this embodiment, it further includes: a second extension edge 122 and a limiting block 113. The second extension edge 122 is a circular member, and the second extension edge 122 is fixed to the top end of the inner layer 12 of the container. The limiting block 113 is fixed to the inner wall of the outer layer 11 of the container and cooperates with the second extension edge 122. The top surface of the limiting block 113 is an inclined surface. After adopting the above scheme, during use, after the inner layer 12 of the container is placed in the outer layer 11 of the container, the second extension edge 122 passes over the limiting block 113, and the limiting block 113 forms a clamping limit on the second extension edge 122, further improving the connection stability between the inner layer 12 of the container and the outer layer 11 of the container.

[0039] Preferably, Figures 1 - 3 As shown, in this embodiment, the outer wall of the second extension edge 122 abuts against the inner wall of the outer layer 11 of the container, ensuring the connection stability between the inner layer 12 of the container and the outer layer 11 of the container and avoiding relative jitter.

[0040] Preferably, Figure 1 and Figure 2 As shown, in this embodiment, it further includes: a first extension edge 112. The first extension edge 112 is a circular member, and the first extension edge 112 is fixed to the top end of the outer layer 11 of the container. The first extension edge 112 is used to fix the sealing cover or heat-sealing film.

[0041] The components not described in detail herein are prior art.

[0042] The working principle and usage process of the present utility model: For the packaging container main body 1 of the present utility model, during use, the outer layer 11 of the container and the inner layer 12 of the container are combined into the packaging container main body 1. The inner layer 12 of the container is made of food-safe material and can be in direct safe contact with food. The outer layer 11 of the container is made of high-strength and wear-resistant plastic and has good impact resistance, which can effectively reduce the risk of container breakage during transportation and handling, and ensure the safety of food during storage, transportation and handling;

[0043] The outer layer 11 of the container and the inner layer 12 of the container are respectively provided with an outer reinforcing rib 114 and an inner reinforcing rib 121, which further improves the structural strength of the outer layer 11 and the inner layer 12 of the container, and is not easily deformed and damaged by extrusion. This not only ensures the safety of the main body 1 of the packaging container, but also ensures the safety of the internal food.

[0044] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
