DETAILED DESCRIPTION

[0033] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0034] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0035] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0036] In the following embodiments, unless otherwise specified, functional components or structures are conventional components or conventional structures used in the art to achieve corresponding functions.

[0037] Embodiment 1:

[0038] like Figure 1-2 As shown, an open three-dimensional packaging box without glue fastening includes a bottom plate 1, a first side plate group 2, a third side plate group 3, a second side plate group 4, and a fourth side plate group 5 which are respectively arranged on four sides of the bottom plate 1 and are folded and connected in sequence to form a cavity, and an overlapping portion 8 and a buckle portion 9 for fastening are provided at the connection between two adjacent side plate groups, and the two ends of the third side plate group 3 and the fourth side plate group 5 are also connected to the first side plate group 2 and the second side plate group 4, respectively.

[0039] The technical solution is mainly to firmly connect the third side panel group 3 and the fourth side panel group 5 which are in relative positions after folding at their adjacent two sides to form the prototype of an open three-dimensional packaging box. When the first side panel group 2 and the second side panel group 4 are folded, the connection between the two adjacent side panel groups is reinforced by the overlapping part 8 and the snap part 9, so that the open three-dimensional packaging box can be fastened and formed without glue.

[0040] In order to better highlight the three-dimensional nature of the open three-dimensional packaging box, in the present technical solution, each side panel group has a double-layer structure after folding, specifically: along the direction toward the bottom plate 1, the first side panel group 2 includes a first bottom side panel 22 that is sequentially connected and overlaps with the bottom plate 1 after folding, a first inner side panel 21 on the inner side of the open three-dimensional packaging box, a first top side panel 23 on the top of the open three-dimensional packaging box, and a first outer side panel 24 on the outer side of the open three-dimensional packaging box; the second side panel group 4 includes a second bottom side panel 42 that is sequentially connected and overlaps with the bottom plate 1 after folding, a second inner side panel 41 on the inner side of the open three-dimensional packaging box, and a second outer side panel 24 on the outer side of the open three-dimensional packaging box. A top side panel 43 and a second outer panel 44 located on the outside of the open three-dimensional packaging box; the third side panel group 3 includes a third bottom side panel 32 connected in sequence and overlapping with the bottom panel 1 after folding, a third inner panel 31 located on the inside of the open three-dimensional packaging box, a third top side panel 33 located on the top of the open three-dimensional packaging box, and a third outer panel 34 located on the outside of the open three-dimensional packaging box; the fourth side panel group 5 includes a fourth bottom side panel 52 connected in sequence and overlapping with the bottom panel 1 after folding, a fourth inner panel 51 located on the inside of the open three-dimensional packaging box, a fourth top side panel 53 located on the top of the open three-dimensional packaging box, and a fourth outer panel 54 located on the outside of the open three-dimensional packaging box.

[0041] In order to ensure seamless connection between two adjacent top side panels, the first top side panel 23, the second top side panel 43, the third top side panel 33, and the fourth top side panel 53 are all trapezoidal structures. After the first top side panel 23, the second top side panel 43, the third top side panel 33, and the fourth top side panel 53 are folded, the adjacent oblique sides are in contact at the top ends respectively. Furthermore, in order to enable the inner side panel to be folded onto the inner side of the open three-dimensional packaging box, the relatively parallel sides of the first top side panel 23 are respectively the same as the side lengths of the first inner side panel 21 and the first outer side panel 24, and the side length of the first inner side panel 21 is smaller than the side length of the first outer side panel 24; the relatively parallel sides of the second top side panel 43 are respectively the same as the side lengths of the second inner side panel 41 and the second outer side panel 44, and the side length of the second inner side panel 41 is smaller than the side length of the second outer side panel 44; the relatively parallel sides of the third top side panel 33 are respectively the same as the side lengths of the third inner side panel 31 and the third outer side panel 34, and the side length of the third inner side panel 31 is smaller than the side length of the third outer side panel 34; the relatively parallel sides of the fourth top side panel 53 are respectively the same as the side lengths of the fourth inner side panel 51 and the fourth outer side panel 54, and the side length of the fourth inner side panel 51 is smaller than the side length of the fourth outer side panel 54. Therefore, since the side length of the inner panel is smaller than that of the outer panel, the top side panel can be located at the top of the open three-dimensional packaging box after folding, and the inner side panel can be located on the inner side of the open three-dimensional packaging box after folding, and the oblique edges of the top side panels on two adjacent sides happen to touch.

[0042] Since there will be a gap in the direction perpendicular to the bottom plate 1 when the oblique edges of the top side plates on two adjacent sides happen to touch, the oblique edges at both ends of the third top side plate 33 are respectively provided with overlapping portions 8 that overlap with the first top side plate 23 and the second top side plate 43 after folding, and the oblique edges at both ends of the fourth top side plate 53 are respectively provided with overlapping portions 8 that overlap with the first top side plate 23 and the second top side plate 43 after folding. The overlapping portions 8 overlap with the first top side plate 23 and the second top side plate 43 respectively to reduce the gap between the adjacent edges and enhance the fastening effect.

[0043] The first cross-linking arm 61 and the second cross-linking arm 62 are symmetrically arranged at both ends of the third inner side panel 31, and the third cross-linking arm 63 and the fourth cross-linking arm 64 are symmetrically arranged at both ends of the fourth inner side panel 51. After the first cross-linking arm 61 and the third cross-linking arm 63 are folded, they are clamped on the side of the first side panel group 2 and are located between the first inner side panel 23 and the first outer side panel 24. After the second cross-linking arm 62 and the fourth cross-linking arm 64 are folded, they are clamped on the side of the second side panel group 4 and are located between the second inner side panel 41 and the second outer side panel 44. The third side panel group 3 and the fourth side panel group 4 on opposite sides are folded and connected to form the prototype of an open three-dimensional packaging box, and the clamping part of the first cross-linking arm 61 and the third cross-linking arm 63 is hidden between the first inner side panel 23 and the first outer side panel 24, and the clamping part of the second cross-linking arm 62 and the fourth cross-linking arm 64 is hidden between the second inner side panel 41 and the second outer side panel 44, so that the open three-dimensional packaging box is more three-dimensional and stylish without affecting the beauty of the open three-dimensional packaging box.

[0044] The connection between the first cross-linking arm 61, the second cross-linking arm 61 and the third inner panel 31, and the connection between the third cross-linking arm 63, the fourth cross-linking arm 64 and the fourth inner panel 51 are provided with a cut-off area 10, and the first inner panel 21 is provided with buckle parts 9 at both ends thereof to be clamped with the cut-off areas 10 on the first cross-linking arm 61 and the third cross-linking arm 63, and the second inner panel 41 is provided with buckle parts 9 at both ends thereof to be clamped with the cut-off areas 10 on the second cross-linking arm 62 and the fourth cross-linking arm 64. The connection between the buckle parts 9 and the cut-off areas 10 makes the connection between the two adjacent inner panels more secure.

[0045] Exemplarily, the buckle parts 9 are arranged at two ends of the first inner side panel 21 close to the first bottom side panel 22, and the buckle parts 9 are also arranged at two ends of the third inner side panel 31 close to the third bottom side panel 32. The first cross-linking arm 61 and the second cross-linking arm 61 are respectively connected to the third inner side panel 31 at the cut-off area 10 close to the third bottom side panel 32, and the third cross-linking arm 63 and the fourth cross-linking arm 64 are respectively connected to the fourth inner side panel 51 at the cut-off area 10 close to the fourth bottom side panel 52, so that after the first side panel group 2, the second side panel group 4, the third side panel group 3, and the fourth side panel group 5 are folded, the buckle parts 9 and the cut-off area are connected at the bottom. The overlapping part 8 at the top cooperates with the connection relationship between the adjacent two side panel groups to tighten.

[0046] Two adjacent side panel groups are connected by an inclined panel group 7, and the inclined panel group 7 includes a first inclined panel 71 connected to one outer panel, and a second inclined panel 72 which is integral with the first inclined panel 71 and connected to the other outer panel, so as to increase the support and stability of the connection between the adjacent side panel groups. In order to better realize the folding of the inclined panel group 7, the first inclined panel 71 and the second inclined panel 72 are discontinuously connected.

[0047] The first bottom side panel 22 and the first inner side panel 21, the second bottom side panel 42 and the second inner side panel 41, the third bottom side panel 32 and the third inner side panel 31, and the fourth bottom side panel 52 and the fourth inner side panel 51 are all discontinuously connected. Exemplarily, two straight line cuts are provided at the connection between the first bottom side panel 22 and the first inner side panel 21, two straight line cuts are provided at the connection between the second bottom side panel 42 and the second inner side panel 41, a straight line cut is provided at the connection between the third bottom side panel 32 and the third inner panel 31, and a straight line cut is provided at the connection between the fourth bottom side panel 52 and the fourth inner panel 51, so as to better realize the folding between the first bottom side panel 22 and the first inner side panel 21, between the second bottom side panel 42 and the second inner panel 41, between the third bottom side panel 32 and the third inner panel 31, and between the fourth bottom side panel 52 and the fourth inner panel 51.

[0048] The first bottom side panel 22, the second bottom side panel 42, the third bottom side panel 32, and the fourth bottom side panel 52 are all trapezoidal. After the first bottom side panel 22, the second bottom side panel 42, the third bottom side panel 32, and the fourth bottom side panel 52 are folded, adjacent oblique edges contact each other at the bottom panel 1, thereby enhancing the close contact between adjacent side panel groups.

[0049] Embodiment 2:

[0050] like Figure 3 , 4As shown, compared with Example 1, most of them are the same, and the only difference is that the first bottom side panel 22 and the first inner side panel 21, the second bottom side panel 42 and the second inner side panel 41, the third bottom side panel 32 and the third inner side panel 31, and the fourth bottom side panel 52 and the fourth inner side panel 51 are all discontinuously connected. For example, two non-linear cuts are provided at the connection between the first bottom side panel 22 and the first inner side panel 21, so that when the first bottom side panel 22 and the first inner side panel 21 are folded, the first bottom side panel 22 also includes a partial reserved area 11 of the first inner panel 21, and the reserved area 1 As the first bottom side panel 22 is folded, it is clamped with the first cross-linking arm 61 and the third cross-linking arm 63 on the side of the first side panel group 2; two non-linear cuts are provided at the connection between the second bottom side panel 42 and the second inner side panel 41, so that when the second bottom side panel 42 and the second inner side panel 41 are folded, the second bottom side panel 42 also includes a partial reserved area 11 of the second inner side panel 41, and the reserved area 11 is clamped with the second cross-linking arm 62 and the fourth cross-linking arm 64 on the side of the second side panel group 4 when the second bottom side panel 42 is folded, so that the first side panel group 2 and the second side panel group 4 are more three-dimensional and fastened. Two non-linear incisions are provided at the connection between the third bottom side panel 32 and the third inner side panel 31, so that when the third bottom side panel 32 and the third inner side panel 31 are folded, the third bottom side panel 32 also includes a partial reserved area 11 of the third inner side panel 31, and the reserved area 11 abuts against the third outer side panel 34 when the third bottom side panel 32 is folded; two non-linear incisions are provided at the connection between the fourth bottom side panel 52 and the fourth inner side panel 51, so that when the fourth bottom side panel 52 and the fourth inner side panel 51 are folded, the fourth bottom side panel 52 also includes a partial reserved area 11 of the fourth inner side panel 51, and the reserved area 11 abuts against the fourth outer side panel 54 when the fourth bottom side panel 52 is folded, thereby making the third side panel group 3 and the fourth side panel group 5 more three-dimensional.
