Description

Technical Field

[0001] The present invention relates to the technical field of product outer packaging, in particular to a packaging box. Background Art

[0002] For gateways or other round, lightweight smart products, most of these products use plastic as the shell, and the internal structure is mainly circuit board components. Generally, these products do not come with metal plugs. At present, the main packaging methods for these products are as follows:

[0003] (1) Use a top and bottom lid packaging box, that is, the packaging lining is independently designed (the lining is made of sponge, blister molding or other paper materials).

[0004] (2) Ordinary tight-fitting white box packaging structure is used. Since the product shell is mostly made of plastic, some do not have buffer protection, or do not have a complete buffer protection solution.

[0005] Among the above methods, method (1) involves cutting and molding sponge sheets and also requires gluing and fixing. The blister molding lining involves mold opening, and the production process is complicated, time-consuming and labor-intensive. Method (2) does not provide sufficient cushioning protection for the product. The finished product may be damaged in appearance or have product dysfunction due to impact, which directly affects the user experience. Summary of the invention

[0026] Please refer to Figure 1 and Figure 2 The present invention provides a packaging box, including a box body cut from a single material and folded into a foldable shape, the box body including a cover plate 1, a bottom plate 2, four side plates 3, two top buffer lining plates 4, and a bottom buffer lining plate 5, wherein:

[0027] The four side panels 3 are connected to each other in sequence. Among the four side panels 3, the top sides of two side panels 3 that are not adjacent to each other are provided with top buffer lining panels 4, and among the other two side panels 3, the top side of one side panel 3 is connected to one side of the cover panel 1;

[0028] The first side edge of the bottom plate 2 is connected to the bottom side edge of a side plate 3, and one of the side edges of the bottom plate 2 except the first side edge is connected to a side edge of the bottom buffer lining plate 5; a self-locking structure for locking each side plate 3 and the bottom plate 2 is formed between the bottom plate 2 and the other side plates 3.

[0029] In the above-mentioned packaging box, the cover plate 1, the bottom plate 2, the four side plates 3, the two top buffer lining plates 4, and the bottom buffer lining plate 5 of the box body are cut from a single material in one piece and folded together, wherein the four side plates 3 are connected to each other in sequence, and among the four side plates 3, the top sides of two non-adjacent side plates 3 are provided with top buffer lining plates 4, and among the other two side plates 3, the top side edge of one side plate 3 is connected to one side edge of the cover plate 1; the first side edge of the bottom plate 2 is connected to the bottom side edge of a side plate 3, and one of the sides of the bottom plate 2 except the first side edge is connected to one side edge of the bottom buffer lining plate 5; a self-locking structure for locking each side plate 3 and the bottom plate 2 is formed between the bottom plate 2 and the other side plates 3. The box body of the packaging box can be prepared by one-piece cutting of a single material, and is assembled into shape through simple folding and buckling. A top buffer lining plate 4 and a bottom buffer lining plate 5 are integrally arranged on the box body. There is no need to prepare or mold the buffer lining separately. The structure is simple and exquisite, which is convenient for rapid production and rapid packaging, and saves costs. The top buffer lining plate 4 and the bottom buffer lining plate 5 can achieve all-round buffering protection for the product, thereby enhancing the user experience.

[0030] In the above-mentioned embodiment of the invention, specifically, the bottom buffer lining plate 5 includes a bearing surface 51 and four support plates 52 arranged on the four sides of the bearing surface 51, wherein one of the support plates 52 is connected to a side of the bottom plate 2 away from the side of the bearing surface 51, and the bottom buffer lining plate 5 is folded toward the inside of the box body along the side where the support plate 52 is connected to the bottom plate 2, and the four support plates 52 are folded toward the bottom plate 2 along the side of the bearing surface 51 so that the support plate 52 is vertically supported on the bottom surface and the bearing surface 51 is parallel to the bottom surface, so as to form a bottom buffer space. The structure of the above-mentioned bottom buffer lining plate 5 makes full use of the extra space inside the packaging box, and the supporting effect of the support plate 52 enables a bottom buffer space to be provided below the bearing surface 51 for bearing the product, forming a good buffer lining protection.

[0031] On the bottom buffer lining plate 5, a plurality of lining tongues 511 and lining slots 512 corresponding to the lining tongues 511 are formed at the four sides of the bearing surface 51. The lining tongues 511 include a first buffer plate 5111 connected to the edge of the bearing surface 51, a first bent plate 5112 connected to the side of the first buffer plate 5111 away from the bearing surface 51, and a second buffer plate 5113 connected to the side of the first bent plate 5112 away from the first buffer plate 5111.
