DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.

[0019] In the description of the present application, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery" and the like indicate the orientation or positional relationship, which are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the components or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0020] In order to solve the problem that the existing one-piece packaging box cannot be separated from the assistance of glue or cannot be stably kept in the folded shape depending on the characteristics of the material and is extremely easy to damage, with reference to Figs. 1-3 The packaging box disclosed by the present application comprises a packaging outer box 10 and a packaging inner box 20. The packaging outer box 10 comprises an outer box bottom plate 11, an outer box back side plate 12 connected to the outer box bottom plate 11, a first outer box upper side plate 13 connected to the outer box back side plate 12, a tongue plate 14 connected to the first outer box upper side plate 13, an outer box front side plate 15 connected to the outer box bottom plate 11, a second outer box upper side plate 16 connected to the outer box front side plate 15, and a slot 17 provided at the joint of the second outer box upper side plate 16 and the outer box front side plate 15.

[0021] After the packaging outer box 10 is closed, the first outer box upper side plate 13 is located above the second outer box upper side plate 16, and the tongue plate 14 is inserted into the slot 17.

[0022] The packaging inner box 20 comprises an inner box bottom plate 21 connected to the right side of the bottom plate, a cross-sectional line 211 obliquely provided on the inner box bottom plate 21, a crease line 212 obliquely folded on the inner box bottom plate 21, an inner box left side plate 22 connected to the inner box bottom plate 21, a first inner box upper side plate 23 connected to the inner box left side plate 22, an inner box right side plate 24 connected to the inner box bottom plate 21, a second inner box upper side plate 25 connected to the inner box right side plate 24, and a fold horizontal line intersecting the cross-sectional line 211 and forming a triangular structure. After the packaging inner box 20 is closed, the inner box bottom plate 21 is folded above the outer box bottom plate 11 along the fold horizontal line.

[0023] The working principle of the packaging box will be described in detail as follows:

[0024] Firstly, the operator places the product above the inner box bottom plate 21 and folds the inner box bottom plate 21 above the outer box bottom plate 11 along the fold horizontal line. In this process, the first inner box upper side plate 23 is overlaid on the second inner box upper side plate 25. Then, the outer box back side plate 12 and the outer box front side plate 15 are folded, and the first outer box upper side plate 13 is overlaid on the second outer box upper side plate 16. Finally, the tongue plate 14 is inserted into the slot 17 to form the packaging outer box 10, thereby realizing the packaging of the product.

[0025] As a conventional material, the packaging outer box 10 and the packaging inner box 20 of the present application are both made of hard corrugated paperboard. The hard corrugated paperboard has better hardness and strong stability, which can meet the use needs of the present application.

[0026] Based on the above description, the packaging box of the present application can maintain its stability after being folded without the need for glue or special material. Meanwhile, the packaging box can be quickly disassembled to form a plane, thereby reducing the occupied area, facilitating storage and transportation, and having strong practicability compared with the prior art.

[0027] The above examples are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable the skilled in the art to understand the content of the present application and to implement it, and cannot limit the protection scope of the present application. Any equivalent transformation or modification made according to the spirit and essence of the present application shall be covered within the protection scope of the present application.
