At this time, the third folding plate 232 and the fourth folding plate 242 are in contact with the second side cover plate 22. That is, the third folding plate 232, the third connecting plate 231, the fourth folding plate 242 and the fourth connecting plate 241 are all located in the same plane, and the third side folding plate 233 and the fourth side folding plate 243 are both perpendicular to the second side cover plate 22.

[0032] The second side cover 22 is folded upward by 90°. At this time, the inner side of the second side cover 22 is in contact with the outer side of the third side panel 33. At this time, the second upper cover 2 covers the second side panel 32, the third side panel 33 and the fourth side panel 34.

[0033] Furthermore, the connection between the lower cover 4 and the first side cover plate 12 and the second side cover plate 22 is provided with a pressing line; the connection between the first side cover plate 12 and the first upper cover plate 11 is provided with a pressing line; the connection between the second side cover plate 22 and the second upper cover plate 21 is provided with a pressing line; the connection between the first folding plate 132, the first connecting plate 131, and the first side folding plate 133 is provided with a third folding line; the connection between the second folding plate 142, the second connecting plate 141, and the second side folding plate 143 is provided with a fourth folding line; the connection between the third folding plate 232, the third connecting plate 231, and the third side folding plate 233 is provided with a fifth folding line; and the connection between the fourth folding plate 242, the fourth connecting plate 241, and the fourth side folding plate 243 is provided with a sixth folding line. The provision of the pressing lines and folding lines facilitates the folding of the various components along them, facilitates the unfolding and folding of the packaging box, and saves time and effort.

[0034] Furthermore, the first folding plate 352 and the second folding plate 353 are both in the shape of a right triangle, the first folding line 354 connects the right-angled vertex of the first folding plate 352 and the hypotenuse of the first folding plate 352, the second folding line 355 connects the right-angled vertex of the second folding plate 353 and the hypotenuse of the second folding plate 353, and the first folding line 354 and the second folding line 355 are arranged in parallel.

[0035] Furthermore, the first connecting plate 131 and the first side cover 12 are fixed by bonding, the second connecting plate 141 and the first side cover 12 are fixed by bonding; the third connecting plate 231 and the second side cover 22 are fixed by bonding, and the fourth connecting plate 241 and the second side cover 22 are fixed by bonding; and the lower end surface of the second folding portion 3522 is fixed by bonding to the inner surface of the lower cover 4. With this structure, only the second folding portion 3522 is bonded to the lower cover 4, while the first folding portion 3521, the third folding portion 3531, and the fourth folding portion 3532 are not bonded to the lower cover 4. When the packaging box is unfolded, the box body 3 is unfolded into a plate-like structure, which saves space and facilitates storage and transportation.

[0036] Furthermore, the first folding piece 13 and the second folding piece 14 are symmetrically arranged, and the third folding piece 23 and the fourth folding piece 24 are symmetrically arranged. The symmetrical arrangement has a better supporting effect and is more beautiful.

[0037] Furthermore, the heights of the first side panel 31, the second side panel 32, the third side panel 33 and the fourth side panel 34 are all the same. The above structure allows the first upper cover panel 11 and the second upper cover panel 21 to flatly cover the upper ends of the first side panel 31, the second side panel 32, the third side panel 33 and the fourth side panel 34, thereby improving the sealing of the packaging box.

[0038] Furthermore, a magnetic sheet is embedded in the side of the first upper cover plate 11 away from the first side cover plate 12, and a magnetic fitting is embedded in the side of the second upper cover plate 21 away from the second side cover plate 22. Due to the magnetic effect, the first upper cover plate 11 and the second upper cover plate 21 will attract and fix each other when they are close to each other, making it difficult for the packaging box to spread apart in the closed state, thereby enhancing the airtightness of the packaging box.

[0039] The first upper cover 1, the second upper cover 2, the box body 3 and the lower cover 4 of the present invention are preferably made of paper, the first upper cover plate 11, the first side cover plate 12, the bottom plate 35, the second side cover plate 22 and the second upper cover plate 21 are processed from a complete piece of paper, the first folding piece 13 is processed from a complete piece of paper, the second folding piece 14 is processed from a complete piece of paper, the third folding piece 23 is processed from a complete piece of paper, and the fourth folding piece 24 is processed from a complete piece of paper.
