[0017] In order to enable the above-mentioned purposes, features and advantages of the utility model to be more clearly understood, the utility model will be further described in detail below in combination with the drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0018] As Figures 1-4 indicated in the utility model, a hexagonal paper lunch box structure scheme is provided, the hexagonal paper lunch box comprises a bottom 1 in a hexagonal shape and a bowl wall 2 extending along the hexagonal bottom as Figure 2 indicated, in the raw material piece constituting the hexagonal paper lunch box in the embodiment, the bowl wall 2 between the adjacent two pieces is provided with a fan-shaped excess material piece 3, and the excess material piece 3 is hot-pressed and attached to the inner side of the bowl wall 2 after the paper lunch box is formed;

[0019] As described above, the internal space of the paper lunch box in this embodiment, which holds food, has no gaps at its corners. The entire box is made of a single piece of raw paper that is hot-pressed and glued together. Considering that the paper material can maintain a stable shape after plastic cooling during hot pressing, and with the hexagonal support structure of this embodiment, the paper lunch box in this embodiment can maintain a stable box-shaped structure during use. Furthermore, based on the multi-layered structure of its corners, its support and stability are even stronger.

[0020] Furthermore, such as Figures 1-2 The bowl wall 2 shown in this embodiment is also provided with a bowl edge 4 that exceeds the length of the scrap sheet 3. After the bowl edge 4 is formed into a paper lunch box, it is heat-pressed and glued together to form a ring-shaped hexagonal bowl edge 5. The hexagonal bowl edge 5 is folded outward to form a bowl rim 11 that is horizontal with the bottom 1. The bowl rim 11 extends downward to form a folded edge 12, and the included angle between two adjacent bowl edge parts 4 is heat-pressed and glued together to form an arc-shaped bowl corner 7. After the paper lunch box is formed, the scrap sheet 3 is attached to the bowl wall 2, and the bowl edge 4 extends horizontally and bends to form the bowl rim 11. After extending a short distance, it extends downward to form the folded edge 12. It is worth noting that both the bowl rim 11 and the folded edge 12 are ring-shaped without gaps in their overall shape. At the connection of the two bowl wall parts 2, they are superimposed on each other by the action of the heat-pressing equipment, which makes the bowl rim 11 stronger and less prone to wrinkles or deformation.

[0021] As a further provision of the above solution, the excess material sheet 3 and the bowl edge 4 are provided with a hot-pressing forming area 6. The hot-pressing forming area 6 is used to fix the hot-pressed overlapping part when forming the paper lunch box. Compared with the ordinary bowl wall 2, the hot-pressing forming area 6 is softened by high temperature when the hexagonal paper lunch box is formed. Considering the strength or the stability of the adhesion, adhesive can also be provided on the outside of the paper lunch box relative to the position of the hot-pressing forming area 6 to further improve its firmness.

[0022] As a further provision of the above scheme, the portions at the ends of the bowl edge 4 that are used for mutual hot pressing and bonding are all extended to both sides. The purpose of this provision is to ensure that when forming a paper lunch box, the bowl edge 11 and the folded edge 12 extending from the bowl edge 4 overlap each other to further form an arc-shaped bowl corner 7 structure.

[0023] As a further feature of the above solution, the bottom 1 is also provided with a bottom groove 8, which is convex inward relative to the bottom 1. The result of the bottom groove 8 is that the middle part of the bottom 1 of the paper lunch box arches inward towards the inside of the lunch box. It is worth noting that the circumference of the bottom 1 of the paper lunch box should not be arched. The arched bottom groove 8 structure can reduce the direct contact between the bottom 1 of the lunch box and the placement area. Firstly, it can reduce heat exchange. Secondly, in conjunction with the lunch box lid with an upward protrusion structure, it can provide a certain limiting and retaining force when multiple paper lunch boxes with lids are stacked.

[0024] As a further provision of the above-mentioned solution, the curling of the excess piece 3 to form a bowl along 11 and the curling of the edge portion 12 comprises a curling structure not limited to a square as shown in Figure 1 or a circular curling structure as shown in Figure 3 , 4 .

[0025] It is apparent that a person skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, it is intended to include them within the scope of the present application.
