The packaging box 10 mentioned herein can be considered as a flat cardboard with appropriate creases set on it, so that it can be folded along the creases into a desired 3D packaging box for packaging of products such as cigarettes and wine.

In the packaging box 10 , the rectangular sheet 11 includes a front sheet 14 , a back sheet 15 and two side sheets 16 , and can be folded along its vertical crease 18 to form a closed rectangular surrounding wall 17 . As shown in FIG. 1 , the side panel 16 , the back panel 15 , the side panel 16 , and the front panel 14 are connected in sequence through a vertical crease 18 . Of course, in order to facilitate the end-to-end connection required when the four enclose the rectangular wall 17 , a side piece 19 is also connected to the outer side of the front piece 14 . In this way, when enclosing the rectangular wall 17 , the side pieces 19 can be stacked and bonded to the inner surface of the outer side pieces 16 . The side panel 19 and the front panel 14 may also be connected by a vertical fold 18 .

Of course, the front piece 14 and the back piece 15 in this embodiment are in a front-to-back relationship, and from different angles, the front piece 14 can also be regarded as being located at the back.

The bottom sealing structure 12 is connected to the lower end of the rectangular sheet 11 and can be folded to close the lower opening of the rectangular surrounding wall 17 . The bottom seal structure 12 can adopt the common 3D packaging box 30 setting form. For example, as shown in the figure, the bottom seal structure 12 includes a bottom sheet 20 connected to the front sheet 14, the back sheet 15 and the lower sides of the two side sheets 16 respectively, and four bottom sheets 20. They are connected to each other in a superimposed state to close the lower opening of the rectangular surrounding wall 17 . The two parts of each bottom sheet 20 can be glued together by overlapping parts, and then the box bottom is formed through the middle notch part, inside and outside, to form the box bottom, which will not be repeated here. Each backsheet 20 and the front panel 14/back panel 15/side panel 16 are also connected by a single crease 28.

The top cover structure 13 is connected to the upper end of the rectangular sheet 11 , and can foldably cover or open the upper opening of the rectangular surrounding wall 17 . The top cover structure 13 includes a cover sheet 21 connected to the upper side of the back sheet 15 , a front folded sheet 22 connected to the upper side of the front sheet 14 , and side folded sheets 23 connected to the upper sides of each side sheet 16 respectively.

The junction of the front folded sheet 22 and the front sheet 14 is provided with parallel and spaced front double folds 24, the front double folds 24 define a front connecting piece 25, and can be folded along the double folds so that the front connecting piece 25 is located in the 3D The state in which the front folded sheet 22 is located within the rectangular enclosure wall 17 within the top surface of the packaging box 30 .

The junction of the side folded sheet 23 and the side sheet 16 is provided with parallel and spaced side double folds 26, the side double folds 26 define side connecting pieces 27, and can be folded along the side double folds 26 to make the side connecting pieces 27 A state in which the side folded sheet 23 is located within the top surface of the 3D packaging box 30 and the side folded sheet 23 is located within the rectangular surrounding wall 17 .

The width of the front connecting piece 25/side connecting piece 27 formed by the front double folds 24/side double folds 26 will be visually reflected as the thickness of the side wall of the box body when the boxes are stacked.

One side of the cover sheet 21 is connected to the back sheet 15 through a single crease 28, and the cover sheet 21 can be folded along the single crease 28 to a position within the top surface of the 3D packaging box 30; The other three sides are respectively connected to a folded edge 29 through a single fold 28; and each folded edge 29 can be folded along the corresponding single fold 28 relative to the cover sheet 21 toward the bottom of the 3D packaging box 30, so that the cover of the top cover structure 13 can be folded toward the bottom of the 3D packaging box 30. In the closed state, each folded edge 29 laterally abuts with the side folded sheet 23/front folded sheet 22 in the rectangular surrounding wall 17, and the cover sheet 21 is adapted to close the opening enclosed by the side connecting sheet 27 and the front connecting sheet 25. As shown in FIG. 1 , in the unfolded state, the single crease 28 at the junction of the cover sheet 21 and the back sheet 15 , the crease of the front double crease 24 close to the side of the bottom seal structure 12 , and the side double crease 26 The folds on the side close to the bottom sealing structure 12 are collinear.

The beneficial effects of the present utility model include:

(1) Due to the double fold structure, the front connecting piece 25, the side connecting piece 27 and the folding edge 29 of the folded and formed 3D packaging box 30 in this solution are in contact with each other, which effectively improves the stiffness of the box body;

(2) The front connecting piece 25 and the side connecting piece 27 are located in the top surface of the 3D packaging box 30, which strengthens the thickness of the edges and corners of the box body, improves the molding effect of the box body, and solves the warping problem of the lid of the 3D packaging box piece 10 in the past;

(3) Effectively enhance the visual effect of the appearance of the 3D packaging box 30, which is suitable for the packaging of tobacco, wine, cosmetics, medicines, exhibits, stationery and other products.

In this embodiment, both the side folded sheet 23 and the front folded sheet 22 are partially cut from both sides of the material to form a trapezoidal structure that is large at the bottom and small at the top. In this way, the folding of the side folded sheet 23/the front folded sheet 22 can be facilitated, and the blocking by the rectangular surrounding wall 17 can be avoided during the folding process. Optionally, the corners of the front folded sheet 22 and the side folded sheet 23 are rounded.

In this embodiment, the side edges of the front folded sheet 22 and the side folded sheet 23 are both sides minus the trapezoidal structure of the lower part of the material and the upper part. The two side folded sheets 23 are respectively matched with the corresponding three sides of the cover sheet 21, and together with the cover sheet 21, form a complete rectangle.
