[0039] Referring to Figure 6The outer box skin 2 comprises an outer box bottom plate 21, two outer box side plates 22 and two outer box face plates 23, the two outer box side plates 22 are connected to the left and right sides of the outer box bottom plate 21 through creases respectively, the left and right outer box side plates 22 are equal in width, the two outer box face plates 23 are connected to the left and right sides of the outer box side plate 22 through creases respectively, and the left and right outer box face plates 23 are equal in width; the inner box bottom plate 11 is at least partially bonded and fixed with the outer box bottom plate 21, so that the inner box skin 1 is assembled on the outer box skin 2; the length and width of the outer box bottom plate 21 are slightly larger than the length and width of the whole inner box bottom plate 11. When in the box state, the outer box side plate 22 is located on the left and right sides of the inner box skin 1, and the outer box face plate 23 covers the opening of the containing space of the inner box skin 1, so that the folding box can be quickly opened and used by opening and closing the left and right outer box face plates 23 of the outer box skin 2; when in the flat state, the outer box skin 2 is a flat rectangle, which is beneficial to flat storage or transportation before being made into a box.

[0040] Referring to Figure 7 and combining Figures 1-4 , the folding lug 3 comprises four folding lugs respectively connecting the corresponding outer box face plate 23 and the outer box side plate 22 to form the four top corners of the outer box skin 2; the four folding lugs 3 are symmetrical and have the same structure, each folding lug 3 comprises a first folding piece 31 bonded and fixed with the outer box face plate 23, a second folding piece 32 bonded and fixed with the outer box side plate 22, a third folding piece 33 connected with the first folding piece 31 through a crease, and a fourth folding piece 34 connected with the second folding piece 32 through a crease, and the third folding piece 33 and the fourth folding piece 34 are connected through a crease. When in the flat state, the third folding piece 33 and the fourth folding piece 34 are folded on the first folding piece 31 and the second folding piece 32 along the creases respectively; when in the box state, the third folding piece 33 is bonded and fixed with the outer box face plate 23, and the fourth folding piece 34 connects the outer box face plate 23 and the side of the outer box side plate 22 to form the three-dimensional top corner structure of the outer box skin 2, and the three-dimensional top corner structure is attached to the top four corners of the inner box skin 1. The folding lug 3 composed of four folding pieces can be folded flat on the outer box skin 2 before being made into a box, so as to facilitate storage or transportation, and in the box state, the first folding piece 31 and the third folding piece 33 are bonded and fixed on the inner side of the outer box face plate 23, so that compared with the existing folding lug connected with the outer box skin through a crease, the stability of the folding box top surface is improved, the overall use stability of the folding box is improved, and the left and right side plates and the two face plates of the outer box skin 2 do not spread after being opened, but maintain the three-dimensional top corner structure, so that the folding and unfolding process of the folding box is more rapid and convenient.

[0041] As an improvement of the folding box of the utility model, referring to Figure 7The first fold piece 31 and the third fold piece 33 are right-angled triangles symmetrical along the crease, and the crease connecting them is the hypotenuse of the triangle. When laid flat, the third fold piece 33 overlaps the first fold piece 31. When in the boxed state, the third fold piece 33 is adhered to the outer box panel 23 and spliced ​​with the first fold piece 31 to form a rectangle. By adopting the above design, before boxing, the third fold piece 33 neatly overlaps the first fold piece 31, and when boxing, the first fold piece 31 and the third fold piece 33 are adhered to the inner side of the outer box panel 23 to form a rectangle with a size close to that of the outer box panel, thereby maximizing the coverage of the inner side of the outer box panel 23 and better improving the firmness of the folding box panel.

[0042] As an improvement to the folding box of this utility model, refer to Figure 7 The second fold piece 32 and the fourth fold piece 34 are right-angled triangles symmetrical along the fold line, and the fold line connecting them is the right-angled side of the triangle. When laid flat, the fourth fold piece 34 overlaps the second fold piece 32; when in the boxed state, the fourth fold piece 34 is perpendicular to the second fold piece 32. By adopting the above design, the fourth fold piece 34 is neatly overlapped on the second fold piece 32 before boxing, and when boxing, the fourth fold piece 34 stands upright and fits against the front and back sides of the inner box shell 1, improving the sturdiness of the folding box side panels.

[0043] Figure 7 This demonstrates the folding process of one of the folding ears (using...) Figure 2 Taking the right front folding ear as an example, the folding ear 3 in this embodiment is composed of four triangular folds. When not fully unfolded, the folding ear 3 is polygonal (see...). Figure 7 (See the diagram on the left); when in a flat position, the folded ear 3 forms a parallelogram (see...). Figure 7 (See the image on the right). The folding structure is easy to follow, and the flat surface is neat and easy to lay out, which is beneficial for production and assembly.

[0044] As an improvement to the folding box of this utility model, the folding box also includes four adhesive components 5, which are used to connect the third folding pieces 33 corresponding to the four folding lugs 3 to the outer box panel respectively. Specifically, the adhesive component 5 is triangular, and the side length of the triangle is smaller than the perimeter of the third folding piece 33 after it is bonded to the outer box panel. The adhesive component 5 is double-sided adhesive. Before the folding box is manufactured and shipped, one side of the adhesive component 5 can be bonded to the third folding piece 33. The other side of the adhesive component 5 is a peelable release paper. When the folding box needs to be used and is folded into a box, the third folding piece 33 can be bonded to the outer box panel 23 by peeling off the release paper of the adhesive component, thereby improving the ease of assembly of the folding box. Of course, in other embodiments, the folding box may not come with adhesive components, and the user can purchase double-sided adhesive to bond and fix it, which can also achieve assembly.

[0045] As an improvement of the folding box, the folding box further comprises an outer box magnet 5, the outer box magnet 5 is magnetically connected with two outer box panels 23, and the left and right butt joints of the outer box skin 2 are used to close the opening of the inner box skin 1. Specifically, the outer box magnet 5 of the present scheme is provided with two, which are respectively embedded on the opposite sides of the outer box panel 23, so that the outer box panel is more flattened in the flat state.

[0046] As described above, the folding box of the present utility model is made of paper material, and no other hardware, plastic or other materials are used except for the outer box magnet, which is more in line with environmental protection requirements and achieves stability by using the design of the outer box magnet. The structure is simple and convenient to make; and like the conventional folding box, it is also flattened, which can save storage and transportation space, and the firmness and load-bearing capacity are improved.

[0047] The above describes the technical solutions provided by the present utility model in detail, and the principles and implementation modes of the present utility model are described by applying specific examples; the above examples are only used to help understand the method and core idea of the present utility model; meanwhile, for those skilled in the art, according to the idea of the present utility model, the specific implementation modes and application ranges can be changed, and the above description should not be understood as a limitation of the present utility model; on the premise of not departing from the concept of the present utility model, several modifications and improvements can be made, which all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent should be subject to the appended claims.
