[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0028] Refer to the accompanying drawings, such as Figure 1-Figure 5 As shown, the utility model discloses a foldable multi-purpose packaging box, which is formed by folding cardboard. Figure 1 An expanded view of the cardboard used to make the packaging box. The cardboard can be kraft paper or corrugated paper.

[0029] Taking a plan view as an example, the cardboard includes a front face 1, a rear face 2, a top face 3, and a bottom face 4. The front face 1 is foldable with the bottom face 4 and the top face 3, and the top face 3 is foldable with the rear face 2. A first notch is provided in the middle of the front face 1. The shape of the first notch can be rectangular or circular. A transparent window 6 is fixedly provided at the position of the first notch. The first notch can extend from the front face 1 to the top face 3; the transparent window 6 can be folded under force, and the transparent window 6 extends from the front face 1 to the top face 3. The material for making the transparent window 6 can be transparent plastic. The transparent window 6 can be fixedly connected to the front face 1 and the top face 3 by gluing.

[0030] A first extension surface 11, a second extension surface 21, a third extension surface 31, and a fourth extension surface 41 are respectively provided on both sides of the front end surface 1, the rear end surface 2, the top surface 3, and the bottom surface 4. The first extension surface 11, the second extension surface 21, the third extension surface 31, and the fourth extension surface 41 move independently of each other during the folding or unfolding process. That is, when the first extension surface 11 is folded, the adjacent fourth extension surface 41 and the third extension surface 31 are not affected.

[0031] The first, second, third, and fourth extension surfaces 11, 21, 31, and 41 are obliquely arranged with a first folding line 12, a second folding line 22, a third folding line 32, and a fourth folding line 42, respectively. One end of the first folding line 12 and one end of the fourth folding line 42 are located at the same point, while the other ends of the two folding lines extend in different directions. The second, second, third, and fourth extension surfaces 11, 21, 31, and 41 are foldable along the first, second, third, and fourth folding lines 42, respectively.

[0032] In the process of folding the cardboard, the portion of the second extension surface 21 located below the second folding line 22 is fixedly connected to the portion of the third extension surface 31 located below the third folding line 32; the portion of the first extension surface 11 located below the first folding line 12 and the portion of the fourth extension surface 41 located below the fourth folding line 42 can be fixedly connected by gluing.

[0033] In addition, an inserting surface 5 is foldably connected to the top of the rear end surface 2 , and the inserting surface 5 is folded and inserted into the gap between the rear end surface 2 and the bottom surface 4 .

[0034] When the packaging box is transformed from the shape shown in the planar unfolded diagram into a cube, the top surface 3 and the bottom surface 4 are folded along the upper and lower edges of the front surface 1, respectively, and the rear surface located above the top surface 3 is bent along the upper edge of the top surface 3; and the first extension surface 11 and the second extension surface 21 are folded inward along the left and right edges of the front surface 1 and the rear surface 2, respectively, to form the two side surfaces of the packaging box. After the first extension surface 11 is folded, the fourth extension surface 41 is folded inward along the two sides of the bottom surface 4, partially overlapped with the first extension surface 11, and then fixed; after the second extension surface 21 is folded, the third extension surface 31 is folded inward along the two sides of the top surface, partially overlapped with the second extension surface 21, and then fixed, as shown in FIG. Figure 2 As shown, the state is in use state. When the box cover needs to be opened, just flip the bottom surface 4 upwards, as shown in FIG. Figure 3 shown.

[0035] When the packaging box is folded from a cube into a flat shape, the top surface 3 and the front surface 1 are coplanar, and the first extension surface 11 and the second extension surface 21 are folded inward along the left and right sides of the front surface 1 and the rear surface 2, respectively. The first extension surface 11 and the second extension surface 21 are folded inward along the first folding line 12 and the second folding line 22, respectively. After the first extension surface 11 is folded, the fourth extension surface 41 is folded inward along the two sides of the bottom surface 4, partially overlapping with the first extension surface 11, and then fixed. After the second extension surface 21 is folded, the third extension surface 31 is folded inward along the two sides of the top surface, partially overlapping with the second extension surface 21, and then fixed. The plug-in surface 5 continues to fold inward to form a flat folded state, as shown in FIG. Figure 5 shown.

[0036] When the packaging box leaves the factory, it is in a flat folded state. The flat folded state takes up less space, is convenient for factory packaging, and will not be crushed. When consumers want to use it, they can unfold it into a Figure 2 The cubic box state can store items in the packaging box, and at the same time, by providing a transparent window 6, it can play a role in displaying items.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
