For ease of understanding, the embodiments described below will be described in detail with respect to the paperboard described above, which may be provided as square paperboard, rectangular paperboard that is not square, and polygonal paperboard, such as that shown in fig. 1, and which may be provided as polygonal paperboard having a generally rectangular outline.

In this embodiment, a part of the area on the cardboard may be used as the top board 10 of the packaging box 100, by folding a part of the board of the remaining area on the cardboard onto another part of the board, the two laminated boards together are used as the side boards 20 of the packaging box 100, and then by folding these side boards 20 to stand up, i.e. perpendicular to the top board 10, and connecting adjacent side boards 20 together to form the coaming assembly, thereby providing the side walls of the packaging box 100 with a double-layered structure.

Specifically, as shown in fig. 1, in some embodiments of the present invention, two transverse folds 30 and two longitudinal folds 30 are disposed on the cardboard, where it should be noted that, in this embodiment, two folds 30 are parallel and perpendicular to the other two folds 30, and two of the folds 30 parallel are transverse folds 30, and the other two are longitudinal folds 30.

It will be appreciated that each crease 30 extends from one edge of the board to the opposite edge, so that four creases 30 divide the board into a nine-sided grid, which for ease of understanding is illustrated in this embodiment as a split area board comprising a cross-shaped panel in the middle and four corner panels 50. The central area 41 of the cross-shaped board is used to form the top board 10 of the packaging box 100, and it should be noted that, the central area 41 in this embodiment refers to an area surrounded by two transverse folds 30 and two longitudinal folds 30.

The four corner plates 50 are respectively positioned at four included angles of the cross-shaped plate, and the four corner plates 50 and the extending blocks 42 of the cross-shaped plate are used for forming coaming components of the packing box 100; it should be noted that the protruding block 42 in this embodiment refers to the remaining four regions except the center block 41 in the cross-shaped plate. It will be appreciated that the four corner panels 50 are integral with the extended sections 42, the centre section 41 of the cross-shaped panel.

Further, in order to equalize the heights of the four side panels 20 of the packing case 100, the sides of the adjacent sides of the four protruding blocks 42 are equalized, so the corner panels 50 between the two protruding blocks 42 are shaped as squares, whereby the four corner panels 50 are arranged as squares of equal area in some embodiments of the present invention.

Specifically, in forming the side panels 20 of the package 100, the corner panels 50 may be folded onto one of the protruding sections 42 adjacent thereto, that is, four corner panels 50 are respectively folded onto four of the protruding sections 42, and each corner panel 50 overlaps with one of the protruding sections 42 to form one of the side panels 20 of the package 100. In addition, when the corner plate 50 is overlapped with the extension block 42, the corner plate 50 can be connected with the extension block 42 by gluing or binding, thereby improving the structural stability of the side plate 20.

In some embodiments of the present invention, the corner panel 50 may be integrally folded and attached to the extension block 42, or a part of the corner panel 50 may be folded and attached to the extension block 42. On this basis, the corner panels 50 may have an area equal to or smaller than the area of the protruding areas 42 to ensure that the inner layer structure of the side panels 20 has an area equal to or smaller than the outer layer structure.

It will be appreciated that the folding of the partial areas of the board requires the provision of a cut in the board, and as shown in figure 1, for example, in some embodiments of the invention, a cut 60 is cut in each corner panel 50, the cut 60 being coincident with the edge of the cross panel, i.e. with the crease 30; or may be positioned close to the edges of the cross-shaped panels, i.e. at a distance from the folds 30.

Note that, in this embodiment, the slit 60 may be a slit formed by cutting, or may be a notch having a certain width; that is, the panels on both sides of the slit 60 may have a certain interval therebetween or may be closely adhered without an interval therebetween, but may be offset from each other in a direction perpendicular to the cardboard.

In this embodiment, as shown in fig. 1, the slits 60 are disposed near the edges of the cross-shaped plate, a certain distance is provided between the slits 60 and the edges of the cross-shaped plate, and four slits 60 are cut perpendicularly from the four edges and extend to the nearest crease 30, i.e. the slits 60 do not exceed the crease 30, as shown in fig. 1, every two adjacent slits 60 are perpendicular, and the four slits 60 on the cardboard are arranged in a cyclone shape.

On this basis, in each corner panel 50, the area between the notch 60 and the fold 30 perpendicular to the notch 60 is a folding plate 51, that is, the notch 60, the fold 30 perpendicular to the notch 60 and the two edges of the corner panel 50 together enclose a folding plate 51, and the folding plate 51 is used to fold and fit along the fold 30 on the extension block 42, that is, the notch 60 is arranged such that the area on the corner panel 50 outside the notch 60 forms the folding plate 51, and as shown in fig. 2, the folding plate 51 can be folded onto the adjacent extension block 42 for forming the side panel 20 of the package 100.

Taking the cardboard shown in fig. 1 as an example, the center block 41 of the cross-shaped board is rectangular with unequal length and width, it will be appreciated that the width of the two protruding blocks 42 in the left-right direction of the cross-shaped board is unequal to the width of the two protruding blocks 42 in the up-down direction. On this basis, in some embodiments of the present invention, the width of the folding plate 51 in the folding direction is equal to the width of the protruding block 42 to which it is attached in the folding direction.

It will be appreciated that the width of the folded plate 51 in the folding direction is equal to the width of the protruding section 42 in the folding direction when folded, which ensures the area range of the double-layered structure of the side plates 20, and ensures that the folded plate 51 does not exceed the boundary of the protruding section 42 after being folded on the protruding section 42, thereby avoiding affecting the connection between the subsequent adjacent side plates 20.
