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 number of the second side plates 21 is two. The second side plates 21 are arranged in one-to-one correspondence with the first side plates 11. 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.

As shown in fig. 4-5, since the first and

second retainers

103 and 203 can rotate relatively, the positioning groove 206 can extend and retract in the length direction by adjusting the first and second included

angles

105 and 205, so as to change the size of the positioning groove 206 according to the size of the product 300, thereby improving the versatility of the paper card liner 100.

As shown in fig. 6, in the second embodiment, the shapes of the first detent 403 and the second detent 503 of the cardboard liner 400 can be designed according to the external shape of the product, and one end of the first detent 403 and the second detent 503 is designed to be step-shaped. In other embodiments, both ends of the first detent 403 and the second detent 503 may be designed to be stepped or have other shapes that match the shape of the product.

Specifically, the first bottom surface 102 and the second bottom surface 202 are located on the same plane in order to stabilize the entire structure. In the present embodiment, the depth of first card slot 104 is equal to the vertical distance between the bottom of second card slot 204 and second bottom surface 202. Of course, in other embodiments, a plurality of support legs may be disposed on both the first bottom surface 102 and the second bottom surface 202 to ensure that the support legs of the first bottom surface 102 and the support legs of the second bottom surface 202 are located on the same plane, and at this time, it is also not necessary to limit the depths of the first card slot 104 and the second card slot 204, or only to provide the first card slot 104 or the second card slot 204, and the first side plate 11 is directly inserted into the second card slot 204 or the second side plate 21 is directly inserted into the first card slot 104.

In other embodiments, the structure of each first side plate 11 may be different, and the structure of each second side plate 21 may be different; the shape of each first clip 103 can be different, and the shape of each second clip 203 can be different; the shapes of the first block-out 103 and the second block-out 203 can be different; according to actual needs, one first side plate 11 may be disposed corresponding to a plurality of second side plates 21, or one second side plate 21 may be disposed corresponding to a plurality of first side plates 11.

In other embodiments, one first detent 103 may be provided corresponding to a plurality of second detents 203, or one second detent 203 may be provided corresponding to a plurality of first detents 103.

In the present embodiment, each first detent 103 corresponds to only one first card slot 104, and each second detent 203 corresponds to only one second card slot 204. In other embodiments, to improve the structural stability, each first detent 103 may correspond to a plurality of first card slots 104, and each second detent 203 may correspond to a plurality of second card slots 204.
