Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] The utility model provides a technical solution: a paper bowl that prevents heat deformation, comprising an outer paper tube 1, a first paper tube ring 2 is provided at the upper end of the outer paper tube 1, a second paper tube ring 3 is provided at the lower end of the outer paper tube 1, the second paper tube ring 3 is adhesively fixed to the inner side of the lower end of the first paper tube ring 2, and a second connecting paperboard 10 is adhesively fixed to the inner side of the outer paper tube 1;

[0029] It also includes an annular bottom plate 13, which is arranged on the lower side of the inner wall of the outer paper tube 1. The annular bottom plate 13 is connected to the lower end of the inner wall of the outer paper tube 1 through a third connecting paper board 12, and the third connecting paper board 12 is adhesively fixed to the annular bottom plate 13 and the outer paper tube 1.

[0030] The bowl cover 4 is also included, which is arranged on the upper end of the outer paper tube 1, and the bowl cover 4 is fastened and fixed to the first paper tube ring 2. The upper end of the bowl cover 4 is provided with a plurality of folding protrusions 5 distributed at equal distances.

[0031] See also Figure 2 A first bowl bottom 6 is provided on the upper side of the inner portion of the outer paper tube 1, and the outer wall of the first bowl bottom 6 is connected to the second connecting paperboard 10. Its inverted frustum design facilitates the natural gathering of food, and the tight connection of the second connecting paperboard 10 not only enhances the stability of the structure, but also ensures the stability of the first bowl bottom 6 when bearing the weight of food, prevents accidental falling off or deformation, and improves the overall safety and durability of use;

[0032] See also Figure 6 The upper end of the annular bottom plate 13 is provided with a plurality of first reinforcing cardboards 14 distributed in a rectangular array. The other side of each first reinforcing cardboard 14 is provided with a second reinforcing cardboard 15. The second reinforcing cardboards 15 form a triangle with the first reinforcing cardboard 14 and the annular bottom plate 13. The triangular structural design not only enhances the load-bearing capacity of the paper bowl, but also effectively reduces the risk of deformation caused by high-temperature food by dispersing pressure, thereby improving the structural strength and stability of the paper bowl.

[0033] See also Figure 5The inner wall of the outer paper tube 1, the outer wall of the annular bottom plate 13 and the third connecting paperboard 12 are all coated with water-based thermal insulation coating 9, forming a layer of efficient thermal insulation barrier, which effectively blocks the transfer of heat and protects the user's hands from being burned by high temperature, while also improving the thermal insulation performance of the paper bowl.

[0034] See also Figure 2 and Figure 4 The second connecting paperboard 10 and the third connecting paperboard 12 are both provided with a number of triangular heat dissipation holes 11 distributed in a circular shape and at equal intervals. The opening of the triangular heat dissipation holes 11 not only reduces the overall weight of the paperboard, but also promotes the effective dissipation of heat, avoids deformation or damage of the paper bowl due to high temperature accumulation, and at the same time improves the comfort experience of the user.

[0035] When in use, when high-temperature food is carefully placed in the first bowl bottom 6, its unique inverted frustum shape naturally guides the food downward to form a compact stack for easy eating. At this time, the third connecting cardboard 12 serves as a key supporting structure, firmly supporting the annular bottom plate 13, thereby effectively lifting the first bowl bottom 6, ensuring its stability when carrying high-temperature food. The first reinforcing cardboard 14 and the second reinforcing cardboard 15 are cleverly combined into a triangular structure. This design not only enhances the load-bearing capacity of the paper bowl, but also effectively alleviates the stress caused by high-temperature food by dispersing the weight of the first bowl bottom 6. The local stress generated by concentrated heating greatly reduces the risk of deformation of the paper bowl due to uneven heating. The second connecting paperboard 10 firmly connects the annular bottom plate 13 and the outer paper tube 1 to form a stable overall structure, which effectively improves the overall rigidity and durability of the paper bowl. In addition, the triangular heat dissipation holes 11 opened on the third connecting paperboard 12 and the second connecting paperboard 10, while reducing the overall weight of the paper bowl, also provide a convenient channel for heat discharge, promote the rapid dissipation of heat inside the paper bowl, and further ensure the safety of the paper bowl in high temperature environments.
