[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] like Figure 1-5 As shown, an environmentally friendly food packaging box with an internal partition includes a food packaging box body 1. A central support column 2 is provided on the inner surfaces of both ends of the food packaging box body 1. A U-shaped elastic food film 3 is provided at the center of the front end of the central support column 2. A food isolation baffle 4 is provided on the upper outer surface of the U-shaped elastic food film 3. Rotating columns 5 are provided on the center of both sides of the food packaging box body 1 and at the center of the upper end of the central support column 2. A sloping rotating baffle 6 is provided on the outer surface of one end of the rotating column 5. Sealing covers 7 are provided on the outer surfaces of the food packaging box body 1 around its perimeter. A rectangular connecting slot 8 is provided at the center of the upper end of the sealing cover 7. The number of rotating columns 5, sloping rotating baffles 6, and rectangular connecting slots 8 are all four sets, and the number of central support columns 2 is two sets.
[0026] It should be noted that this utility model is an environmentally friendly food packaging box with an internal partition. In use, it comprises a food packaging box body 1, a central support column 2, a U-shaped elastic food film 3, a food isolation baffle 4, a rotating column 5, a sloping rotating baffle 6, a sealing cover 7, and a rectangular connecting slot 8. When packaging food, the food is first lowered and placed inside the food packaging box body 1. During placement, the food pushes the food isolation baffle 4, which in turn stretches the U-shaped elastic food film 3, thus isolating the food stored separately inside the food packaging box body 1 and preventing contact between the foods. This allows for rapid adjustment of the size of the two sets of storage spaces inside. After the food is stored inside the food packaging box body 1, the sealing cover 7 is aligned and connected to the four sides of the food packaging box body 1. During installation, the food packaging box body 1 and the central support column... The rotating column 5 on the 2nd floor pushes the sloping rotating baffle 6 through the rectangular connecting slot 8 on the sealing cover 7. During the passage, the sloping rotating baffle 6 achieves precise alignment with the rectangular connecting slot 8 through its own structure. After alignment, the sloping rotating baffle 6 is pressed higher than the sealing cover 7 by pressing. After pressing, the rotating column 5 completes the rotation of the sloping rotating baffle 6. Through the misaligned connection between the sloping rotating baffle 6 and the rectangular connecting slot 8, the food packaging box body 1 and the sealing cover 7 are sealed together to complete the food storage. First, the food packaging box is made of corn starch, which is biodegradable and environmentally friendly. In addition, the two sets of internal storage spaces can be adjusted according to the different sizes of the stored food, which has good applicability and reduces the cost of use. At the same time, the misaligned connection method can complete the quick opening of the packaging box and prevent the food from scattering when opening.
