[0026] See the instruction manual appendix Figure 1 To the instruction manual Figure 6 As shown schematically, a curved packaging box according to the present invention is illustrated. The curved packaging box is a box-shaped body formed by bending a single piece of sheet material. The box-shaped body includes:

[0027] Base plate 1, first arc plate 2, top plate 3, second arc plate 4, first inner buckle plate 5, and second inner buckle plate 6.

[0028] The bottom plate 1 is connected in sequence to a first arc plate 2, a top plate 3, and a second arc plate 4. The bottom plate 1, the first arc plate 2, the top plate 3, and the second arc plate 4 are connected in sequence to form the side wall of the packaging box. The bottom plate 1 and the top plate 3 are arranged opposite each other, and the first arc plate 2 and the second arc plate 4 are arranged opposite each other.

[0029] The edges of the first arc-shaped plate 2 and the second arc-shaped plate 4 that are not connected to the bottom plate 1 or the top plate 3 are set to be arc-shaped.

[0030] The two sides of the base plate 1 that are not connected to the first arc plate 2 or the second arc plate 4 are respectively connected to the first inner buckle plate 5 and the second inner buckle plate 6. The first inner buckle plate 5 is bent towards the top plate 3 to form a curved surface, and the second inner buckle plate 6 is bent towards the first inner buckle plate 5 to form a curved surface.

[0031] A connector 7 is provided on the side where the base plate 1 connects to the second arc-shaped plate 4. The connector 7 and the second arc-shaped plate 4 can be glued together. Thus, the base plate 1, the first arc-shaped plate 2, the top plate 3, and the second arc-shaped plate 4 form the side wall of the packaging box. (Refer to the attached instruction manual.) Figure 2 As shown.

[0032] Specifically, connector 7 can be located on the inner side of the side wall of the packaging box. This conceals connector 7 within the box's storage space, further ensuring the overall aesthetic appeal of the packaging box.

[0033] Reference manual attached Figure 2 As shown, the top plate 3 is provided with a first locking hole 31, the first inner buckle plate 5 is provided with a second locking hole 51 and a first locking piece 52, and the second inner buckle plate 6 is provided with a second locking piece 61.

[0034] When the first inner buckle plate 5 bends toward the top plate 3, the first locking piece 52 on the first inner buckle plate 5 engages with the first locking hole 31, connecting the first inner buckle plate 5 and the top plate 3 together. (Refer to the attached instruction manual.) Figure 3 As shown. At this time, the side wall of the packaging box and the first inner buckle plate 5 together form the accommodating space of the packaging box, and the contents to be packaged can be put into the packaging box through the opening formed by the bottom plate 1, the first arc plate 2, the top plate 3 and the second arc plate 4.

[0035] When the second inner buckle plate 6 bends toward the first inner buckle plate 5, the second locking hole 51 on the first inner buckle plate 5 engages with the second locking piece 61 on the second inner buckle plate 6, connecting the second inner buckle plate 6 to the first inner buckle plate 5. (Refer to the attached instruction manual.) Figure 4 As shown, the instruction manual is attached. Figure 4 This is a front view of a curved packaging box according to one embodiment of the utility model.

[0036] When the top plate 3 is provided with a third locking hole 32, and the position of the third locking hole 32 corresponds to the second locking hole 51, the second locking piece 61 simultaneously engages with both the second locking hole 51 and the third locking hole 32, connecting the top plate 3, the first inner buckle plate 5, and the second inner buckle plate 6. This makes the connections between the various parts of the packaging box more secure and reliable, improving the structural stability of the packaging box.

[0037] The third locking hole 32 is located on the side of the first locking hole 31 near the connection line between the first inner buckle plate 5 and the bottom plate 1. Therefore, after the second inner buckle plate 6 is bent, the second inner buckle plate 6 and the first inner buckle plate 5 achieve cross-locking, that is, the locking position of the first inner buckle plate 5 and the top plate 3 is close to the connection point between the second inner buckle plate 6 and the bottom plate 1, and the locking position of the second inner buckle plate 6 and the top plate 3 is close to the connection point between the first inner buckle plate 5 and the bottom plate 1, which can further improve the structural stability of the packaging box.

[0038] In an optional embodiment, the first inner buckle plate 5 includes a first bending portion 53 and a first connecting portion 54. The first bending portion 53 is connected to the base plate 1 and is used to bend into a curved surface. The first connecting portion 54 is located on the side of the first bending portion 53 away from the base plate 1 and is used to connect to the top plate 3. All four corners of the first bending portion 53 are set as arc-shaped notches.

[0039] In an optional embodiment, the second inner buckle plate 6 includes a second bent portion 62 and a second connecting portion 63. The second bent portion 62 is connected to the base plate 1 and is used to bend into a curved surface. The second connecting portion 63 is disposed on the side of the second bent portion 62 away from the base plate 1 and is used to connect to the first inner buckle plate 5. All four corners of the second bent portion 62 are set as arc-shaped notches.

[0040] Reference manual attached Figure 1 The maximum length H of the first bending portion 53 or the second bending portion 62 along the first direction is not less than the arc length of the arc in the first arc plate 2 and the second arc plate 4. Therefore, the first bending portion 53 or the second bending portion 62 can completely wrap the arc portion of the first arc plate 2 and the second arc plate 4 after bending.

[0041] The maximum length L1 of the first bending portion 53 or the second bending portion 62 along the second direction is greater than the length of the base plate 1 along the second direction. The minimum length L2 of the first bending portion 53 or the second bending portion 62 along the second direction is equal to the length of the base plate 1 along the second direction. The first direction is perpendicular to the second direction, and the second direction is parallel to the line connecting the first bending portion 53 and the base plate 1.

[0042] Therefore, by setting arc-shaped notches at the four corners of the first bending part 53 and the second bending part 62, the first bending part 53 and the second bending part 62 have two lengths along the second direction. The minimum length should be the same as the length of the bottom plate 1 and the top plate 3 along the second direction. This setting can make the width of the top and bottom surfaces of the packaging box consistent, making the overall structure of the packaging box more regular. The maximum length should be greater than the length of the bottom plate 1 and the top plate 3 along the second direction. This setting can make the first bending part 53 and the second bending part 62 protrude slightly beyond the first arc plate 2 and the second arc plate 4 in the second direction after bending, so that the contents to be packaged will not leak out from the gaps, and avoid poor contact between the first arc plate 2 and the first bending part 53, the second arc plate 4 and the second bending part 62, which would reduce the overall wrapping performance of the packaging box.

[0043] Reference manual attached Figure 5 Included with instruction manual Figure 6 The diagram shows a three-dimensional view of a curved packaging box from different angles. It should be understood that, due to the different designs of the locking holes and locking pieces, there may be a small gap or no gap between the first inner buckle plate 5, the second inner buckle plate 6, and the top plate 3 when no external force is applied.

[0044] In an optional embodiment, the one-piece sheet can be rigid cardboard.

[0045] The beneficial effects of the technical solution provided by this utility model are that, through the setting and cooperation of the arc plate and the inner buckle plate, while ensuring the storage function of the packaging box, the shape of the packaging box is curved. Compared with the existing cubic packaging box, it reduces the risk of scratching people, avoids the probability of bumps and damage during use and movement, makes the packaging box more beautiful, can be used in more scenarios, and improves the applicability of the packaging box.

[0046] The above are merely some embodiments of this utility model, used only to illustrate the technical solution of this utility model, and not to limit it. It should be understood that those skilled in the art can make improvements or substitutions based on the above description without departing from the inventive concept of this utility model, and all such improvements and substitutions should fall within the protection scope of the appended claims of this utility model. In this case, all details can be replaced with equivalent elements, and the materials, shapes, and sizes can also be arbitrary.
