Description

Technical Field

[0001] The utility model relates to the field of packaging tools, in particular to a flip-molded top and bottom cover packaging box. Background Art

[0002] A top-and-bottom lid packaging box is a commonly used packaging box. Patent publication CN209225592U discloses a top-and-bottom lid packaging box. The side walls of the box body of this structure are all single-layered, so the side walls of the box body of this structure do not have a buffering function. Once the box body is impacted by external objects when packaging items, the side walls of the box body cannot play a buffering and shock-absorbing role, which will cause the items packaged in the box body to be easily damaged. In addition, the folding and forming steps are cumbersome, slow, and labor-intensive. Utility Model Content

[0003] In response to the above-mentioned problems, the present invention proposes a flip-molded top and bottom lid packaging box, the side walls of which are side walls with cavities. The presence of the cavity can cushion the contents placed in the box body, reducing the probability of the items placed in the box body being damaged by foreign objects, and the box body can be quickly flipped and formed.

[0004] The technical solutions adopted by this utility model are as follows:

[0005] A flip-molded top and bottom lid packaging box includes a bottom sheet, which is a rectangular bottom sheet, and is provided with a first outer sheet, a second outer sheet, a third outer sheet and a fourth outer sheet along the four edges of the bottom sheet, the first outer sheet, the second outer sheet, the third outer sheet and the fourth outer sheet being perpendicular to the bottom sheet, and further including a first inner sheet, a second inner sheet, a third inner sheet and a fourth inner sheet, the first inner sheet being connected to the first outer sheet through a first top sheet, the second inner sheet being connected to the second outer sheet through a second top sheet, the third inner sheet being connected to the third outer sheet through a third top sheet, and the fourth inner sheet being connected to the fourth outer sheet through a fourth top sheet, the first top sheet, the second top sheet, the third top sheet and the fourth top sheet are in the same plane, the first inner sheet and the first outer sheet are in a parallel and non-contacting state, the second inner sheet and the second outer sheet are in a parallel and non-contacting state, the third inner sheet and the third outer sheet are in a parallel and non-contacting state, and the fourth inner sheet and the fourth outer sheet are in a parallel and non-contacting state.

[0006] Specifically in this packaging box, the bottom sheet, the first outer sheet, the second outer sheet, the third outer sheet, the fourth outer sheet, the first inner sheet, the second inner sheet, the third inner sheet and the fourth inner sheet are enclosed together to form a box body.

[0007] This packaging box further adds a first inner piece, a second inner piece, a third inner piece and a fourth inner piece on the basis of the first outer piece, the second outer piece, the third outer piece and the fourth outer piece. The first inner piece and the first outer piece are parallel and non-contacting, the second inner piece and the second outer piece are parallel and non-contacting, the third inner piece and the third outer piece are parallel and non-contacting, and the fourth inner piece and the fourth outer piece are parallel and non-contacting. This is equivalent to the side walls around the four edges of the box body being side walls with cavities. The existence of the cavity can buffer the contents placed in the box body and reduce the probability of the items placed in the box body being damaged by foreign objects.

[0008] In summary, in this packaging box, the side wall of the box body is a side wall with a cavity. The presence of the cavity can buffer the contents placed in the box body, reduce the probability of the items placed in the box body being damaged by foreign objects, and quickly flip the box body into shape.

[0014] Optionally, the second inner piece is provided with a first inner folding piece and a second inner folding piece at both ends, and the third inner folding piece and a fourth inner folding piece are provided at both ends of the fourth inner piece, the first inner folding piece and the fourth inner folding piece are closely attached to the first inner piece, and the second inner folding piece and the third inner folding piece are closely attached to the third inner piece.

[0015] The first inner folding piece, the second inner folding piece, the third inner folding piece and the fourth inner folding piece are provided to prevent dust from penetrating into the cavity of the side wall.

[0016] Optionally, the first inner sheet is connected to a first bottom sheet, the second inner sheet is connected to a second bottom sheet, and the first bottom sheet and the second bottom sheet are both tightly attached to the bottom sheet.

[0017] The first bottom patch can support the first inner sheet, and the second bottom patch can support the second inner sheet.

[0018] Optionally, a first abutting piece is provided on the first bottom patch, and a second abutting piece is provided on the second bottom patch. The first abutting piece abuts against the first outer piece, and the second abutting piece abuts against the third outer piece.

[0019] The first abutting piece abuts the first outer piece to keep the first outer piece and the first inner piece stable, and the second abutting piece abuts the third outer piece to keep the third outer piece and the third inner piece stable.

[0020] Optionally, a first expansion piece is provided on the second inner piece, and a second expansion piece is provided on the fourth inner piece. The first expansion piece abuts against the second outer piece, and the second expansion piece abuts against the fourth outer piece.
