[0027] Embodiment 1

[0028] A fast food box body, as Figures 1-5 shown, includes a bottom of the box 1, a body of the box 2 and a mouth of the box 3. The upper and lower ends of the body of the box 2 are correspondingly connected to the mouth of the box 3 and the bottom of the box 1 to form a bowl-shaped container with a circular mouth. A step surface 4 is formed at the connection between the body of the box 2 and the mouth of the box 3, which is used to facilitate placing a partition layer above or inside the body of the box 2. The connection between the bottom of the box 1 and the body of the box 2 forms a connecting inclined surface 5 through an inclined chamfer. Preferably, the inclined chamfer is 45°.

[0029] Among them, the mouth of the box 3 is an annular groove structure with a lower opening 31, and its cross-section is in a "J" shape or an "Ω" shape with an inward concave lower end, which is used to facilitate latching and sealing with the box cover. A pull tab 32 extends outward on the horizontal flange outside the mouth of the box 3, and a latching boss 33 (which can also be a concave latching groove) that protrudes upward is provided on the pull tab 32. The pull tab 32 serves as a starting point when opening the box cover latched on the box body, facilitating the user to exert force. A circular bump 11 that accommodates upward is provided in the middle of the bottom of the box 1, and a convex ring 12 is further provided outside the circular bump 11. The circular bump 11 and the convex ring 12 strengthen the structure of the bottom of the box 1, and thus the overall anti-deformation ability of the box body is strong.

[0030] The box body 2 has several reinforcing columns 21 evenly distributed around its circumference, each receiving into the inner cavity of the box. Each reinforcing column 21 has an isosceles trapezoidal structure in its horizontal cross-section, with the upper and lower bases of the trapezoid gradually increasing in size from the step surface 4 towards the bottom 1. The reinforcing columns 21 create a continuous convex-concave structure on one side and a concave side on the other. This invention enhances the strength of the box body 2 by creating this convex-concave structure through the reinforcing columns 21. Preferably, to further improve the strength and rigidity of the box body 2, a triangular prism 22 receiving into the inner cavity of the box is provided at the vertical center of each reinforcing column 21. The triangular prism 22 has a triangular pyramidal structure, gradually increasing in size from top to bottom, with its top lower than the step surface 4. More preferably, the connection between the box body 2 and the connecting inclined surface 5 is provided with an irregularly shaped column 23 that is received into the box body. The irregularly shaped column 23 is formed by combining a triangular pyramid-shaped column (small triangular column) located at the root of the box body 2 and a triangular pyramid-shaped column located on the connecting inclined surface 5.

[0031] Preferably, when two adjacent reinforcing columns 21 are spaced apart, the spacing between them is controlled so that the shape of the box body 2 formed between the two adjacent reinforcing columns 21 is similar to the shape and size of the reinforcing columns 21, but in the opposite direction, i.e., an inverted reinforcing column (viewed from the outside of the box, the box body in this part has a horizontal cross-section that is an isosceles trapezoidal shape with the top and bottom edges gradually decreasing from the step towards the bottom of the box). By controlling the spacing between the two adjacent reinforcing columns 21, the box body is also made more aesthetically pleasing.

[0032] Preferably, the box body 2 and the reinforcing column 21 are arc-shaped structures that bulge inward in the vertical cross-section. This design makes the box body 2 appear as an arc-shaped structure bulging inward towards the center of the box when viewed from the side and front views, thus enhancing the strength of the box body 2 and improving the overall safety of the box body after it is closed with the lid.

[0033] Example 2

[0034] like Figures 6-8 As shown, this embodiment is basically the same as embodiment one, except that the box body in this embodiment has a directional structure, with several reinforcing columns 21 evenly distributed on the four sides of the box body 2. The bottom 1 of the box is provided with an upward-facing square protrusion 13 in the middle, and the square protrusion 13 is provided with several upward-facing protruding strips 14.

[0035] In Examples 1 and 2, the connections between the surfaces of various parts of the box (the connections between the inclined surfaces and the box body and the bottom, as well as the connections between the box body and the reinforcing pillars, triangular pillars, etc.) are all transitioned by small rounded corners. The small rounded corners are set to prevent product demolding and thus prevent defects such as product tearing.

[0036] This utility model is not limited to the specific embodiments described above. For those skilled in the art, all modifications made based on the above concept without creative effort fall within the protection scope of this utility model.
