As shown in fig. 1 and 2, the package box according to the embodiment of the present application includes an outer shell and a retractable paper card liner 100 accommodated therein. The paper card liner 100 includes a first paper card 10 and a second paper card 20 inserted into each other.
The first paper card 10 is an integrally formed structure, and includes at least two first side plates 11 capable of being bent relatively. In the present embodiment, the number of the first side plates 11 is two. Each of the first side panels 11 has the same structure, and includes a first top side 101 and a first bottom side 102 opposite to each other. The first top edge 101 and the first bottom surface 102 both extend along the extending direction of the first side plate 11. The first top edge 101 is provided with a first stopper 103. The first detents 103 are each identical in shape to one another. The first bottom surface 102 is provided with a first slot 104 corresponding to the first detent 103. Two adjacent first side panels 11 are folded to form a first included angle 105 smaller than 180 degrees. Of course, in other embodiments, the structure of each first side plate 11 may be different, and the shape of each first detent 103 may also be different.
The first paper card 10 is cross-connected with the corresponding second paper card 20, and the cross angle is adjustable. The second paper card 20 is an integrally formed structure, and includes at least two second side plates 21 that correspond to the first side plate 11 and can be bent relatively.

In the present embodiment, the structure of the second side plate 21 is the same as that of the first side plate 11. Each of the second side panels 21 has the same structure, and includes a second top edge 201 and a second bottom edge 202 that are opposite to each other. The second top edge 201 and the second bottom edge 202 both extend along the extending direction of the second side plate 21. The second top edge 201 is provided with a second detent 203. The second detents 203 are each shaped the same as one another. The bottom of the second clip 203 is provided with a second clip groove 204. Two adjacent second side plates 21 are folded to form a second included angle 205 smaller than 180 degrees. The second detent 203 is disposed corresponding to the first detent 103, and the second slot 204 is disposed corresponding to the first slot 104. The second slot 204 is inserted into the corresponding first slot 104, and the second included angle 205 is opposite to the first included angle 105, so that the first clip 103 and the second clip 203 are mutually crossed to form a positioning slot 206 adapted to the shape of the product 300, for fixedly supporting the product 300 (as shown in fig. 3). That is, the first included angle 105 and the second included angle 205 form two inner corners of the positioning groove 206. The shape of the positioning slot 206 can be adjusted to adjust the angle of intersection between the first paper card 10 and the corresponding second paper card 20.
In order to protect and fix the product 300 more firmly, the bottom surface of the first stopper 103 and the bottom surface of the second stopper 203 are located on the same plane, and the depth of the second slot 204 is equal to the vertical distance between the bottom surface of the first stopper 103 and the bottom surface of the first slot 104. In this embodiment, the first detent 103 and the second detent 203 are both rectangular parallelepiped grooves, and the depth of the first detent 103 is equal to the depth of the second detent 203. Of course, in other embodiments, the parameters of the first card slot 103, the second card slot 203, the first card slot 104 and the second card slot 204 can be designed as required.
