Description

Technical Field

[0001] This utility model belongs to the field of packaging box technology, specifically relating to a PET white film-based biodegradable food packaging box. Background Technology

[0002] As the core carrier for product protection and transportation, the performance of packaging boxes directly affects food preservation and user experience. Currently, the mainstream food packaging boxes on the market use PET white film-based biodegradable materials. While these offer environmental advantages, they also have significant drawbacks in practical applications:

[0003] Currently, PET white film-based biodegradable food packaging boxes are widely used for food packaging. However, these boxes consist of a top cover and a bottom support, and while their structure is simple, their pressure resistance and load-bearing capacity are poor, making them prone to deformation and causing the food inside to be squeezed and deformed. Therefore, it is necessary to design a PET white film-based biodegradable food packaging box to solve the above problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to Figures 1 to 4 This utility model provides a technical solution for a biodegradable food packaging box based on PET white film: it includes a lower packaging box 1 and a top packaging box 3 installed on one side of the lower packaging box 1. A cushioning component is installed at the bottom of the lower packaging box 1. The material of the structural layer of the cushioning component is the same as that of the top packaging box 3 and the lower packaging box 1, and both have biodegradable properties.

[0023] The cushioning assembly includes a platform 11 bonded to the bottom of the lower tray 1 of the packaging box, a corrugated liner 10 fixedly connected to the bottom of the platform 11, and a base 7 fixedly connected to the bottom of the corrugated liner 10. The platform 11 at the bottom of the lower tray 1 of the packaging box is fixedly connected to the corrugated liner 10, and the base 7 is fixedly connected to the bottom of the corrugated liner 10. After the upper cover 3 of the packaging box is closed relative to the lower tray 1 of the packaging box, the packaging box is placed relative to the supporting surface and subjected to pressure, resulting in elastic deformation and excellent pressure resistance.

[0024] A support plate 6 is fixedly connected to the surface of the lower support 1 of the packaging box. The surface of the support plate 6 has through holes at equal intervals. The support plate 6 is located on one side of the bottom support 7. The bottom end of the support plate 6 is flush with the bottom support 7. The support plate 6 plays a supporting role. When the bottom support 7 is attached to the supporting surface, the bottom end of the support plate 6 is also attached to the supporting surface, thus playing an auxiliary supporting role. A connecting platform A101 is fixedly connected to the surface of the lower support 1 of the packaging box. A connecting platform B301 is fixedly connected to the surface of the upper cover 3 of the packaging box. The connecting platforms A101 and B301 are fixedly connected. The lower support 1 of the packaging box and the upper cover 3 of the packaging box are fixedly connected through the connecting platforms A101 and B301, which facilitates the rotation of the upper cover 3 of the packaging box and the removal of the food inside. A positioning groove 2 is opened on the surface of the lower support 1 of the packaging box. A positioning post 4 is fixedly connected to the surface of the upper cover 3 of the packaging box. The positioning post 4 and the positioning groove 2 are inserted and correspond to each other. When the upper cover 3 of the packaging box is pressed against the lower support 1 of the packaging box, the positioning post 4 and the positioning groove 2 are inserted and correspond to each other, resulting in good sealing.

[0025] As can be seen from the above description, this utility model has the following beneficial effects: The base 11 at the bottom of the packaging box lower support 1 is fixedly connected to the corrugated liner 10, and the bottom of the corrugated liner 10 is fixedly connected to the bottom support 7. After the packaging box upper cover 3 is closed relative to the packaging box lower support 1, the packaging box is placed relative to the support surface and undergoes elastic deformation under pressure, thus having good pressure resistance. When the bottom support 7 is attached to the support surface, the bottom end of the auxiliary plate 6 is also attached to the support surface, thus playing an auxiliary support role.

[0026] Example 2: Please refer to Figures 1 to 4 As shown, based on Embodiment 1, this utility model provides a technical solution for a biodegradable food packaging box based on PET white film: an insulating cotton pad 8 is adhered to the outer surface of the packaging box cover 3, extending to the end face of the packaging box cover 3. The insulating cotton pad 8 insulates the food inside the packaging box cover 3, reducing heat loss. Isolation protrusions 9 are equidistantly arranged on the surface of the insulating cotton pad 8, providing excellent isolation and protection. Protective pads 5 are fixedly connected to both ends of the packaging box cover 3. Weight-reducing grooves 501 are equidistantly opened on the surface of the protective pads 5, providing protection against accidental contact at both ends of the packaging box cover 3. The materials of the isolation protrusions 9 and the protective pads 5 are the same as those of the packaging box cover 3.

[0027] Using the above technical solution, the heat insulation pad 8 extends to the end face of the packaging box cover 3. The heat insulation pad 8 keeps the food inside the packaging box cover 3 warm and reduces heat loss. The surface of the heat insulation pad 8 is provided with isolation protrusions 9 at equal intervals. The isolation protrusions 9 have a good isolation and protection effect.

[0028] The working principle and usage process of this utility model are as follows: A corrugated liner 10 is fixedly connected to the base 11 at the bottom of the lower packaging box support 1. A base support 7 is fixedly connected to the bottom of the corrugated liner 10. After the upper packaging box cover 3 is closed relative to the lower packaging box support 1, the packaging box is placed relative to the supporting surface. Under pressure, it undergoes elastic deformation, exhibiting excellent pressure resistance. When the base support 7 adheres to the supporting surface, the bottom end of the auxiliary plate 6 also adheres to the supporting surface, thus providing auxiliary support. The lower packaging box support 1 and the upper packaging box cover 3 are fixedly connected by connecting platforms A101 and B301, facilitating the rotation of the packaging box. The top cover 3 is used to remove the food inside the packaging box. The surface of the lower support 1 of the packaging box has a positioning groove 2. The surface of the top cover 3 of the packaging box is fixedly connected to a positioning post 4. The positioning post 4 and the positioning groove 2 are inserted and correspond to each other. When the top cover 3 of the packaging box is pressed against the lower support 1 of the packaging box, the positioning post 4 and the positioning groove 2 are inserted and correspond to each other, resulting in good sealing. The heat insulation pad 8 extends to the end face of the top cover 3 of the packaging box. The heat insulation pad 8 keeps the food inside the top cover 3 of the packaging box warm and reduces heat loss. The surface of the heat insulation pad 8 is provided with isolation protrusions 9 at equal intervals. The isolation protrusions 9 have a good isolation and protection effect.
