Description

Technical Field

[0001] The utility model relates to the technical field of food packaging boxes, in particular to a pressure-resistant food packaging box which is convenient for packaging. Background Art

[0002] The main functions of food packaging boxes include protecting products, facilitating transportation, improving product quality and promoting sales. In order to improve the stability of food packaging boxes during transportation, food packaging boxes themselves are often made of hard paper products, which in turn improves the stability of food transportation. However, the pressure resistance of existing hard paper products after being subjected to force is poor, especially the sides and tops of the food packaging boxes. When subjected to force, they deform and squeeze the objects inside the food packaging box, and even tear when the deformation of the food packaging box reaches the upper limit, making the food packaging box unusable, thereby reducing the stability of the food packaging box for food transportation.

The two ends of the four packaging box side panels 2 are connected end to end in sequence, the bottoms of the four packaging box side panels 2 are all arranged on the top of the packaging box bottom panel 3, and the two packaging box lids 1 are all arranged on the top of the packaging box bottom panel 3. The four packaging box side panels 2, the two packaging box lids 1 and the packaging box bottom panel 3 are an integrated molding structure, and the four packaging box side panels 2, the two packaging box lids 1 and the packaging box bottom panel 3 are all made of hard cardboard.

[0025] An inner lining circular plate 8 is provided on the top of the bottom plate 3 of the packaging box. The inner lining circular plate 8 is located between the four side plates 2 of the packaging box. A plurality of supporting circular tubes 7 are provided between the outside of the inner lining circular plate 8 and the sides of the four side plates 2 of the packaging box. The food is placed inside the inner lining circular plate 8. The plurality of supporting circular tubes 7 are mainly based on their geometric shape and mechanical properties. When the supporting circular tubes 7 are subjected to external pressure, their arc surfaces can effectively disperse the pressure and avoid local stress concentration, so that the supporting circular tubes 7 can better disperse and resist the pressure when subjected to external pressure, thereby improving the overall pressure resistance and improving the stability of the food packaging box after the side is subjected to force.

[0026] A plurality of second support members 5 are provided above the inner lining circular plate 8, and the top ends of the plurality of second support members 5 correspond to the positions of the bottom ends of the two packaging box covers 1 respectively. After the top ends of the second support members 5 are subjected to force, the force is dispersedly transmitted to the two bottom ends of the second support members 5, which can maintain the integrity of the structure when subjected to force, thereby effectively resisting the external pressure on the packaging box cover and improving the stability of the force on the packaging box cover 1.

[0027] A support plate 6 is provided on the top of the inner lining circular plate 8, and the bottom ends of multiple second support members 5 are installed on the top of the support plate 6.
