[0036] In order to better understand this application, Figures 1 to 7 The packaging box and cardboard structure of the embodiment of the present application are described in detail.

[0037] like Figure 1 and Figure 2As shown, a packaging box provided by an embodiment of the first aspect of the present application includes a box body and an inner card structure, the box body includes four triangular side panels 100, the four triangular side panels 100 are enclosed to form a tetrahedron structure and form a cavity 300, the box body has four vertex corners 101, and each vertex corner 101 is formed by three side panels 100; the inner card structure is arranged in the cavity 300, the inner card structure includes at least one inner panel 200, at least one inner panel 200 is connected to the three side panels 100 and is spaced apart from the vertex corner 101 formed by the three side panels 100, so that a sub-cavity 310 is formed between at least one inner panel 200 and the vertex corner 101.

[0038] In this embodiment, four triangular side panels 100 enclose a tetrahedron structure and form a cavity 300. The cavity 300 can be used to accommodate the items to be packaged.

The inner panel 200 is connected to the three side panels 100 and is spaced apart from the vertex 101 formed by the three side panels 100, so that a sub-cavity 310 is formed between at least one inner panel 200 and the vertex 101. The inner panel 200 divides the cavity 300 into areas, thereby facilitating the zoning of the items to be packaged.

[0039] In some embodiments, the rice dumplings are generally tetrahedral in structure, and the tetrahedral packaging box used for packaging the rice dumplings can enhance the aesthetics of the packaging box.
