[0002] Box sleeves are a common packaging structure, used as outer covers for gift boxes or as book jackets. The structure is generally cylindrical, made by folding and gluing together flat blanks. To ensure structural strength, existing box sleeve blanks typically increase the area for gluing, but this results in the blank's thickness at the gluing location being greater than in other parts of the sleeve, causing overall deformation. Alternatively, to overcome deformation, some box sleeve blanks are glued and fixed at the end faces, but the small gluing area leads to lower structural stability.

[0023] Figure 1 The structure of an exemplary box sleeve blank 100 consistent with some embodiments of the present invention is shown. In this embodiment, the box sleeve blank 100 is used for folding and forming into a box sleeve structure (see [link]). Figure 2 See also Figure 1 The box blank 100 includes a first structural layer 110, a second structural layer 120, a first groove 130 and a plurality of second grooves 140.

[0024] The first structural layer 110 is generally planar in shape. Specifically, in some embodiments, the first structural layer 110 includes materials such as cardboard, gray board, and plastic board. The first structural layer 110 has two flat sides and the thickness of the first structural layer 110 is uniform at different locations.

[0025] The second structural layer 120 is disposed on one side of the first structural layer 110 and is attached to the first structural layer 110. In some embodiments, the second structural layer 120 is generally planar in shape and has a uniform thickness at different locations. In some embodiments, the side of the second structural layer 120 away from the first structural layer 110 may have a preset shape or structure, which can achieve different presentation effects after the box blank 100 is formed into a box structure. For example, the side of the second structural layer 120 away from the first structural layer 110 may have a decorative planar image or a three-dimensional structure.

[0026] The surfaces of the second structural layer 120 and the first structural layer 110 are bonded together. According to a preferred embodiment of the present invention, the surfaces of the second structural layer 120 and the first structural layer 110 are bonded and fixed together. Alternatively, in some embodiments, both the first structural layer 110 and the second structural layer 120 comprise a plastic sheet, and the first structural layer 110 and the second structural layer 120 can be heat-pressed and fixed together. In some embodiments, the first structural layer 110 and the second structural layer 120 can be integrally formed.

[0027] See Figure 1 The first groove 130 is located in the first structural layer 110, and the bottom of the first groove 130 abuts against or is close to the surface of the first structural layer 110 that is in contact with the second structural layer 120, and the first groove 130 is along a straight line ( Figure 1 The first groove 130 extends perpendicular to the plane of the paper. It may penetrate the first structural layer 110 or extend to the surface near the first structural layer 110 where it meets the second structural layer 120, but does not penetrate the first structural layer 110. The depth dimension of the first groove 130 is less than or equal to the thickness dimension of the first structural layer 110, and the first groove 130 does not extend into the second structural layer 120. In some embodiments, the first groove 130 may be formed by cutting from the surface of the first structural layer 110, or, in some embodiments, the first groove 130 may be retained during the molding of the first structural layer 130. The first groove 130 and the first structural layer 120 are integrally formed.

[0028] In this embodiment, the box sleeve blank 100 includes a plurality of second grooves 140, for example Figure 1 As shown, the box sleeve blank 100 includes three second grooves 140. In different embodiments, the box sleeve blank 100 includes two, four, or more second grooves 140. Specifically, the number of second grooves 140 in the box sleeve blank 100 is determined according to the preset shape of the formed box sleeve structure. For example, if the preset shape of the box sleeve structure is a pentagonal prism, the corresponding box sleeve blank 100 may include four second grooves 140.

[0029] In this embodiment, a plurality of second grooves 140 extend in a straight line within the plane of the first structural layer 110, and the plurality of second grooves 140 penetrate the first structural layer 110 in the depth direction, extending to the surface of the second structural layer 120 away from the first structural layer 110, and the second grooves 140 do not penetrate the second structural layer 120, maintaining the overall integrity of the box blank 100. In some embodiments, the second grooves 140 can be formed by cutting the first structural layer 110 and the second structural layer 120 as a whole after the first structural layer 110 and the second structural layer 120 are attached and fixed, which helps to improve the positional accuracy and consistency of the second grooves 140. In this embodiment, the second grooves 140 do not penetrate the second structural layer 120, and the second structural layer 120 remains connected on the side away from the first structural layer 110. In some embodiments, the side of the second structural layer 120 away from the first structural layer 110 has a face paper or cover, which improves the visual presentation effect of the second structural layer 120 and enhances the structural stability of the second structural layer 120.

[0030] See Figure 1 In this embodiment, the first structural layer 110 and the second structural layer 120 are in the first direction ( Figure 1 The components in the first structural layer 110 (shown in the horizontal direction) are partially misaligned. In other words, a portion of the structure in the first structural layer 110 extends beyond the scope of the second structural layer 120 in the first direction. A portion of the structure in the second structural layer 120 extends beyond the scope of the first structural layer 110 in the first direction. In some embodiments, the shape and size of the first structural layer 110 and the second structural layer 120 in directions other than the first direction may be the same or different. Preferably, the shape and size of the first structural layer 110 in directions other than the first direction is less than or equal to the shape and size of the second structural layer 120 in directions other than the first direction.

[0031] The first groove 130 is located near the edge where the first structural layer 110 and the second structural layer 120 are misaligned, for example... Figure 1 As shown, the right edge of the first structural layer 110. Furthermore, the first groove 130 does not extend beyond the range of the second structural layer 120, for example, in... Figure 1 In the vertical direction shown, the projection of the first groove 130 is within the range of the projection of the second structural layer 120.

[0032] In this embodiment, the first structural layer 110 and the second structural layer 120 can be bent at the position of the second groove 140 to form a box-like structure. The first structural layer 110 and the second structural layer 120 fit together, which helps to improve the overall structural strength of the box-like structure. The first structural layer 110 extends beyond the range of the second structural layer 120, and the first groove 130 is close to the misaligned edge of the first structural layer 110 and the second structural layer 120, but does not exceed the range of the second structural layer 120. The bending of the first structural layer 110 at the position of the first groove 130 allows it to combine with the second structural layer 120, increasing the bonding area and improving the structural stability of the box-like structure. It can also reduce or avoid the overlap of the second structural layer 120, reducing the risk of overall deformation of the box-like structure.

[0033] In some embodiments, the box blank may further include a third structural layer or more structural layers, the third structural layer being stacked with the first and second structural layers, and the third structural layer may be bonded to either the first or second structural layer. Increasing the number of structural layers in the box blank helps to improve the structural strength of the box structure.

[0034] In some embodiments, the box blank includes a third structural layer or more structural layers. Taking the third structural layer being bonded to the side of the first structural layer away from the second structural layer as an example, the structural and positional relationship between the third and first structural layers can be similar to that between the first and second structural layers. Specifically, the third and first structural layers are partially misaligned in a first direction, and after bending, the portions of the first and third structural layers extending beyond the range of the first structural layer are fixedly connected, increasing the bonding area between the third and first structural layers and improving the structural strength of the box structure.

[0035] See Figure 1 According to a preferred embodiment of the present invention, the extension directions of the plurality of second grooves 140 are parallel, and the extension directions of the plurality of second grooves 140 are parallel to those of the first groove 130, all along the second direction (perpendicular to the second direction). Figure 1 The first structural layer 110 extends in the direction of the paper surface. Furthermore, in this embodiment, the plurality of second grooves 140 and the first groove 130 all extend to both ends of the first structural layer 110 in the second direction. See also... Figure 1 According to a preferred embodiment of the present invention, the first direction is substantially perpendicular to the second direction.

[0036] Furthermore, the first groove 130 extends in the second direction to both ends of the first structural layer 110. The second groove 140 extends in the second direction to both ends of the first structural layer 110 and the second structural layer 120. The first structural layer 110 and the second structural layer 120 can be bent in the same direction at the location of the second groove 140 to form a box-like structure, avoiding the extension direction of the second groove 140.

[0037] In some embodiments, the box blank 100 further includes a third groove (not shown in the figure), which is located on one side of the first structural layer 110, or the third groove extends through the first structural layer 100 to the second structural layer 120. The first structural layer 110 or the second structural layer 120 may be bent at the location of the third groove to form a more complex three-dimensional shape, such as forming a cylindrical shape with a closed bottom or top. The first structural layer 110 or the second structural layer 120 may be bent at the location of the third groove to form a bottom plate or a top plate.

[0038] In a preferred embodiment of this utility model, in the second direction, the size of the first structural layer 110 is less than or equal to the size of the second structural layer 120. Furthermore, the second structural layer 120 completely covers the first structural layer 110 in the second direction. After the box blank 100 is folded and formed into a box structure, the first structural layer 110 is completely located inside the second structural layer 120, which helps to improve the appearance consistency of the box structure.

[0039] See Figure 2 According to a preferred embodiment of the present invention, the first structural layer 110 is bent along a first direction at the positions of the plurality of second grooves 140 until they are connected end to end. The second structural layer 120 is also bent along the first direction at the positions of the plurality of second grooves 140 until they are connected end to end, forming a box-like structure. Preferably, the first structural layer 110 constitutes the inner sidewall of the box-like structure, and the second structural layer 120 constitutes the outer sidewall of the box-like structure. In this embodiment, the first structural layer 110 and the second structural layer 120 are partially misaligned in the first direction. The connection point where the first structural layer 110 is connected end to end is misaligned with the connection point where the second structural layer 120 is connected end to end. At the misaligned positions, the first structural layer 110 and the second structural layer 120 can be attached and glued together for fixation, increasing the bonding area between the first structural layer 110 and the second structural layer 120 and improving the stability of the box-like structure.

[0040] See Figure 1According to a preferred embodiment of the present invention, the first groove 130 and the second groove 140 are approximately V-shaped. At the V-shaped gaps inside the first groove 130 and the second groove 140, the first structural layer 110 and the second structural layer 120 can approach each other to avoid overlap, guiding the bending position, preventing structural compression, and helping to prevent deformation of the box sleeve structure. Further, in a preferred embodiment of the present invention, the angle of the V-shape of the first groove 130 and the second groove 140 can be determined according to the preset shape of the box sleeve structure. For example, if the cross-sectional shape of the box sleeve structure is approximately rectangular, the angle of the V-shape of the first groove 130 and the second groove 140 can be approximately 90°. In some embodiments, the V-shape of the first groove 130 and the second groove 140 can be asymmetrical, so that after the box sleeve blank 100 is bent and formed, the inner surfaces of the first groove 130 and the second groove 140 approach or fit together.

[0041] See Figure 1 According to a preferred embodiment of the present invention, in the first direction, the dimension 'a' between the edges of the first groove 130 and the first structural layer 110 (for ease of showing the structure of the box blank 100) is... Figure 1 The dimensions of the box sleeve blank have been enlarged to 100. Figure 1 (The dimensional proportions of the box blank 100 are not limited) The portion of the portion of the box blank outside the first structural layer 110 extending into the second structural layer 120 is equal to or less than the corresponding side dimension b in the box (see Figure 2 The first structural layer 110 and the second structural layer 120 are formed by bending. Figure 2 The box sleeve structure 10 shown is illustrated. The portion of the first structural layer 110 extending beyond the range of the second structural layer 120 is bent to form part of the inner side surface of the box sleeve structure 10. In this embodiment, the dimension of the structure 111 between the first groove 130 and the edge of the first structural layer 110 is equal to or smaller than the dimension b of the corresponding side surface in the box sleeve structure 10 after the portion of the first structural layer 110 extending beyond the range of the second structural layer 120 is bent. This simplifies the structure of the box sleeve blank 100 and improves its stability.

[0042] In this design, the structural bend between the edges of the first groove 130 and the first structural layer 110 forms part of the inner wall of the box sleeve structure. The dimension 'a' between the edges of the first groove 130 and the first structural layer 110 increases but does not exceed the bend position of the first structural layer 110. The structure between the edges of the first groove 130 and the first structural layer 110 can fit with the second structural layer 120, increasing the structural stability of the box sleeve structure. In some embodiments, the dimension 'a' between the edges of the first groove 130 and the first structural layer 110 is within an appropriate range. For example, the portion 111 of the first structural layer 110 extending beyond the second structural layer 120 corresponds to one-third to one-half the dimension 'b' of the side edge in the box sleeve. This is beneficial for reducing the size of the box sleeve blank 100 in the first direction while increasing the bonding area, facilitating the storage and transportation of the box sleeve blank 100.

[0043] See Figure 1 According to a preferred embodiment of the present invention, in the first direction, the dimension c of the second structural layer 120 extending beyond the range of the first structural layer 110 is less than or equal to the dimension a between the first groove 130 and the edge of the first structural layer 110. See also Figure 2 In this embodiment, the first structural layer 110 and the second structural layer 120 are bent in the same direction (e.g., a first direction) at the position of the second groove 140 until they are connected end to end. The dimension c of the second structural layer 120 extending outside the range of the first structural layer 110 is less than or equal to the dimension a between the edges of the first groove 130 and the first structural layer 110, so that the structure of the second structural layer 120 extending outside the range of the first structural layer 110 can be bonded and fixed to the structure between the edges of the first groove 130 and the first structural layer 110. Preferably, the dimension c of the second structural layer 120 extending outside the range of the first structural layer 110 is equal to or slightly less than the dimension a between the edges of the first groove 130 and the first structural layer 110.

[0044] See Figure 1 In a preferred embodiment of this invention, in a first direction, the dimension d between the edges of the first groove 130 and the second structural layer 120 is approximately equal to the thickness e of the second structural layer 120. See also Figure 2 After bending the first structural layer 110 and the second structural layer 120, the portion of the second structural layer 120 extending beyond the range of the first structural layer 110 is bonded and fixed to the portion of the first structural layer 110 extending beyond the range of the second structural layer 120. The dimension d between the edges of the first groove 130 and the second structural layer 120 is approximately equal to the thickness e of the second structural layer 120, which allows the first structural layer 110 and the second structural layer 120 to fit together. Furthermore, the end face of the second structural layer 120 in the thickness direction fits together with the second structural layer 120. The overall sidewall thickness of the box sleeve structure is uniform, reducing the risk of deformation of the box sleeve structure.

[0045] In some embodiments, the first groove 130 is aligned with the edge of the second structural layer 120, and the second structural layer 120 can be attached to and bonded to the portion of the first structural layer 110 extending beyond the range of the second structural layer 120 and the side edge of the second structural layer 120.

[0046] See Figure 2 The embodiments of this utility model also include a box sleeve structure 10, which is formed by bending the box sleeve blank 100 as described in the previous embodiments until the ends are connected. Further, according to a preferred embodiment of this utility model, in the box sleeve blank 100, the portion of the first structural layer 110 extending beyond the range of the second structural layer 120 is bonded and fixed to the portion of the second structural layer 120 extending beyond the range of the first structural layer 110, thereby improving the structural stability of the box sleeve structure 10.

[0047] Finally, it should be noted that the above descriptions are merely embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
