[0005] A split type packaging box, comprising a box body and an inner liner, the top of the box body is provided with an open mouth for inserting the inner liner, the box body comprises a plurality of first side surfaces and a first bottom surface, the first side surfaces are provided with a buckle portion, the inner liner comprises a plurality of second side surfaces and a second bottom surface, the first side surfaces are tightly attached to the second side surfaces, and the first bottom surface is tightly attached to the second bottom surface, the side edges of a single side surface are folded into a reinforcing portion, the supporting portion is in the shape of a polygon, and a remaining edge is left, the remaining edge is combined with the buckle portion to limit the displacement of the inner liner.
[0006] As a preferred, the front of the box body is provided with a display opening, and the two sides of the display opening are inwardly bent to form a buckle portion.
[0007] As a preferred, the reinforcing portion is a prism or a prismatoid.
[0008] As a preferred, the reinforcing portion is a triangular prism.
[0009] As a preferred, the box body is a cuboid or a square.
[0010] As a preferred, the box body is integrally formed.
[0011] As a preferred, the height of the reinforcing portion is equal to the vertical height of the first side surface of the box body.
[0012] Compared with the prior art, the utility model has the following advantages:
[0013] 1. Packaging production and assembly are simple, and efficiency can be improved.
[0014] 2. The triangular structure of the inner liner at the four corners can increase the empty box compression resistance of the carton and make the stacking more stable;
[0015] 3. The paper material area is reduced, and the total packaging cost is reduced;
[0016] 4. The four sides are integrated, so that even after stacking and pressure, the single-sided paperboard will not expand outward. BRIEF DESCRIPTION OF DRAWINGS

[0026] In order to make the purpose, technical scheme and advantages of the utility model clearer, the technical scheme of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope protected by the utility model.
[0027] As Figures 1-3 shown, a split type packaging box comprises a carton 1 and an inner liner 2, and the carton 1 can be a cuboid or a cube. The embodiment is a cuboid, and the carton 1 is integrally formed.
[0028] The top of the box 1 is provided with an open mouth into which the inner liner 2 is placed, the inner liner 2 is placed in the box 1, the box 1 comprises four first side faces 11 and a first bottom face 12, and the inner liner 2 comprises two second side faces 21 and a second bottom face 22, wherein the second side face 21 is tightly attached to the first side face 11, and the second bottom face 22 is tightly attached to the first bottom face 12.
[0029] Further, the front face of the box 1 is provided with a display opening 14, and the two sides of the display opening 14 are inwardly bent to form a buckle part 13.
[0030] Further, as shown in Figure 4 in order to strengthen the combination of the box 1 and the inner liner 2, the side edges of a single side face are folded into a reinforcing part 23, the reinforcing part 23 is in the shape of a polygonal body, and a surplus edge 24 is reserved, the inwardly bent buckle part 13 binds the surplus edge 24 of the reinforcing part 23, so that the inner liner 2 cannot easily move in the transverse direction when being placed in the box 1, and in addition, the combination of the surplus edge 24 and the buckle part 13 limits the displacement of the inner liner 2. The reinforcing part 23 is a prism or a prism body, and in the embodiment, the reinforcing part 23 is a triangular prism.
[0031] As shown in Figure 5 is a schematic view of the unfolding of the box 1, wherein the face where the display opening 14 of the box 1 is located is at A, and the corresponding faces are all inwardly bent to form the box 1.
