[0033] The outer shell 10 includes a first outer plate 11, a second outer plate 12, a third outer plate 13, and a fourth outer plate 14 arranged in sequence. There are creases between the first outer plate 11 and the second outer plate 12, between the second outer plate 12 and the third outer plate 13, and between the third outer plate 13 and the fourth outer plate 14, so that any two of the first outer plate 11, the second outer plate 12, the third outer plate 13, and the fourth outer plate 14 can rotate relative to each other.
[0034] The inner box 20 includes an inner box panel 21 and an inner box connecting paper layer 22. The inner box panel 21 includes a first inner panel 211, a second inner panel 212, a third inner panel 213, and a fourth inner panel 214 arranged sequentially, forming a square frame 215. Creases are provided between the first inner panel 211 and the second inner panel 212, between the second inner panel 212 and the third inner panel 213, and between the third inner panel 213 and the fourth inner panel 214, allowing any two of the first inner panel 211, the second inner panel 212, the third inner panel 213, and the fourth inner panel 214 to rotate relative to each other.
[0035] The inner box connecting paper layer 22 includes a first connecting layer 221 and second connecting layers 222 disposed around the perimeter of the first connecting paper layer. Each second connecting layer 222 is respectively covered on each inner sidewall of the frame 215, so that each inner sidewall of the frame 215 is covered with a second connecting layer 222. The first connecting layer 221 is located at the bottom inner side of the frame 215. The first connecting layer 221 has two alternating first connecting parts 2211 and two second connecting parts 2212. The two first connecting parts 2211 and the two second connecting parts 2212 are arranged clockwise or counterclockwise around the inner center of the frame 215, and the two first connecting parts 2211 are separated from each other. Along the clockwise or counterclockwise direction, one side of each first connecting part 2211 has a crease between it and one of the adjacent second connecting parts 2212, and the other side of each first connecting part 2211 is separated from the other adjacent second connecting part 2212. One of the first connecting layers 2211 is fixedly connected to the inner surface of the fourth outer plate 14 by adhesive bonding, while the other first connecting layers 2211 and second connecting layers 2212 are not fixedly bonded to the fourth outer plate 14.
[0036] The first connecting layer 221 is generally rectangular. A portion of the first connecting layer 221 is cut using a cutting tool to separate the two first connecting layers 2211, and to separate the other side of the first connecting layer 2211 from another adjacent second connecting layer 2212. Figure 10 In the diagram, the solid line inside the dashed rectangle indicates the cutting position of the cutting tool; by embossing on the first connecting layer 221, a crease is formed between one side of the first connecting layer 2211 and one of the adjacent second connecting layers 2212. Figure 10 In the diagram, the dashed line inside the dashed rectangle indicates the location of the crease.
[0037] As described above, the packaging box can be folded when the product and inner liner are not placed inside. Figure 4 As shown, the packaging box can be quickly folded flat, which is simple and quick to operate. The packaging box can be formed or reset instantly, and the whole box can be directly flattened back to a flat one-piece state. It occupies very little space when stored and transported, reducing space waste. Therefore, it can be stored and transported easily by folding flat.
