The left side plate 20 is provided with a left connecting plate 21 on the left side, and the right side plate 30 is provided with a right connecting plate 31 on the right side. The first mounting wings 60 and the left connecting plate 21 and the first mounting wings 60 and the right connecting plate 31 constitute a first waste paper cutting area 2001. The first mounting wings 60 and the right connecting plate 31 constitute a first waste paper cutting area 2001, and the first mounting wings 60 and the second mounting wings 70 constitute a second waste paper cutting area 2002.

[0026] Specifically, compared with the prior art, in the first aspect, by providing a left side plate 20 and a right side plate 30 on both sides of the box bottom plate 10, and providing first mounting wings 60 at both the front and rear ends of the left side plate 20 and the right side plate 30, and providing second mounting wings 70 at both the left and right ends of the front side plate 40 and the rear side plate 50, a left connecting plate 21 is provided on the left side of the left side plate 20, and a right connecting plate 31 is provided on the right side of the right side plate 30; with this structure, the first mounting wings 60 and the left connecting plate 21 and the first mounting wings 60 and the right connecting plate 31 can form a first waste paper cutting area 2001, and the first mounting wings 60 and the second mounting wings 70 can form a second waste paper cutting area 2002, so that the cardboard sheet 200 can be die-cut. In the process of forming the inner box sheet 100 by stamping, only the cardboard in the first waste paper cutting area 2001 and the second waste paper cutting area 2002 needs to be removed to obtain the entire inner box sheet 100. The raw material utilization rate of the cardboard sheet 200 can reach more than 90%, thereby reducing the waste rate of cardboard and further reducing the manufacturing cost of the inner box. Secondly, by reasonably arranging the positions of the left side plate 20, right side plate 30, front side plate 40, rear side plate 50, left connecting plate 21, right connecting plate 31, first mounting wing 60 and second mounting wing 70, it is beneficial to improve the convenience for operators to fold the inner box sheet 100 into an inner box, thereby further improving the folding efficiency of the inner box.

[0027] Preferably, the cardboard sheet 200 is made from recycled pulp, which improves its toughness and provides good recyclability. Furthermore, the cardboard sheet 200 can be supplied in sheets, resulting in low transportation costs and eliminating concerns about dents from stacking.

[0028] In some embodiments, the left side panel 20 includes a left vertical panel 22 and a left horizontal panel 23. The left vertical panel 22 is integrally formed on the left side of the box bottom panel 10, and the left horizontal panel 23 is integrally formed on the left side of the left vertical panel 22. Folding lines 80 are provided between the left vertical panel 22 and the box bottom panel 10, and between the left vertical panel 22 and the left horizontal panel 23. When the left vertical panel 22 is folded upward and to the right by 90 degrees along the folding line 80, the left horizontal panel 23 can be folded to the right and downward by 90 degrees along the folding line 80, so that the left vertical panel 22 is perpendicular to the box bottom panel 10, and the left horizontal panel 23 is parallel to the box bottom panel 10.

[0029] Specifically, the left connecting plate 21 is integrally formed on the left side of the left horizontal plate 23, and a fold line 80 is provided between the left connecting plate 21 and the left horizontal plate 23; the first mounting wing 60 is integrally formed on the front and rear ends of the left horizontal plate 23, and a fold line 80 is provided between the first mounting wing 60 and the left horizontal plate 23; when the left connecting plate 21 is folded down and to the left by 90 degrees along the fold line 80 and parallel to the left vertical plate 22, the left vertical plate 22, the left horizontal plate 23 and the left connecting plate 21 form the first receiving area; when the first mounting wing 60 is folded down along the fold line 80, it can cover the front and rear ends of the first receiving area.

[0030] Continuing from above, the right side panel 30 includes a right vertical panel 32 and a right horizontal panel 33; the right vertical panel 32 is integrally formed on the right side of the box bottom panel 10, and the right horizontal panel 33 is integrally formed on the right side of the right vertical panel 32. Folding lines 80 are provided between the right vertical panel 32 and the box bottom panel 10 and between the right vertical panel 32 and the right horizontal panel 33; when the right vertical panel 32 is folded upward and to the left by 90 degrees along the folding line 80, the right horizontal panel 33 can be folded to the left and downward by 90 degrees along the folding line 80, so that the right vertical panel 32 is perpendicular to the box bottom panel 10, and the right horizontal panel 33 is parallel to the box bottom panel 10.

[0031] More specifically, the right connecting plate 31 is integrally formed on the right side of the right horizontal plate 33, and a fold line 80 is provided between the right connecting plate 31 and the right horizontal plate 33; the first mounting wing 60 is integrally formed on the front and rear ends of the right horizontal plate 33, and a fold line 80 is provided between the first mounting wing 60 and the right horizontal plate 33; when the right connecting plate 31 is folded down and to the left by 90 degrees along the fold line 80 and parallel to the right vertical plate 32, the right vertical plate 32, the right horizontal plate 33 and the right connecting plate 31 enclose the second receiving area; when the first mounting wing 60 is folded down along the fold line 80, it can cover the front and rear ends of the second receiving area.

[0032] Preferably, after the left connecting plate 21 and the right connecting plate 31 are folded, the left connecting plate 21 and the right connecting plate 31 are stacked on the left and right sides and fixed by adhesive. This creates a stable first and second storage area, which is commonly used for packaging main units and accessories and other products that need to be placed separately. This achieves orderly storage and improves the user experience.

[0033] In other embodiments, the left horizontal plate 23 is cut with a left handle plate 24, which can be folded upward along the fold line 80 of the left connecting plate 21 and the left horizontal plate 23; the right horizontal plate 33 is cut with a right handle plate 34, which can be folded upward along the fold line 80 of the right connecting plate 31 and the right horizontal plate 33. With this structure, the left handle plate 24 and the right handle plate 34 can be obtained simply by cutting the sheet material, without needing to remove the cardboard sheet 200, thus further reducing cardboard waste. Simultaneously, by directly cutting the handle plate from the inner box sheet 100, the user does not need to install an additional handle, making opening convenient.

[0034] Specifically, a fold line 80 is provided between the front side panel 40 and the bottom panel 10, and a fold line 80 is provided between the rear side panel 50 and the bottom panel 10; the front side panel 40 is folded upward and backward at 90 degrees along the fold line 80, and overlaps with the first mounting wing 60 front and back; the rear side panel 50 is folded upward and forward at 90 degrees along the fold line 80, and overlaps with the first mounting wing 60 front and back; the second mounting wing 70 of the front side panel 40 is folded backward at 90 degrees, so that the second mounting wing 70 overlaps with the left vertical panel 22 and the right vertical panel 32 inside and outside respectively; the second mounting wing 70 of the rear side panel 50 is folded forward at 90 degrees, so that the second mounting wing 70 overlaps with the left vertical panel 22 and the right vertical panel 32 inside and outside respectively. This structure, by having the first mounting wing 60 fold downwards to cover the front and rear ends of the receiving area, provides lateral and lateral enclosed protection for the product placed inside, preventing it from shaking or falling off during transportation. Simultaneously, the overlapping of the front / rear side panels 50 with the first mounting wing 60, and the overlapping of the second mounting wing 70 with the left / right vertical panels 32, create an interlocking structure similar to mortise and tenon joints. This greatly enhances the structural stability of the box in both vertical and horizontal directions, making it more robust and durable.

[0035] More specifically, the front-to-back lengths of the left connecting plate 21, left horizontal plate 23, left vertical plate 22, right vertical plate 32, right horizontal plate 33, and right connecting plate 31 are the same as the front-to-back length of the box bottom plate 10; the left-to-right width of the left horizontal plate 23 is the same as the left-to-right width of the right horizontal plate 33, and the left-to-right width of the left vertical plate 22 is half the left-to-right width of the left horizontal plate 23; the left-to-right width of the left horizontal plate 23 is half the left-to-right width of the box bottom plate 10. The left-to-right widths of the front side plate 40 and rear side plate 50 are the same as the left-to-right widths of the box bottom plate 10, the left-to-right width of the first mounting wing 60 is the same as the left-to-right width of the left horizontal plate 23, and the left-to-right width of the second mounting wing 70 is the same as the left-to-right width of the left vertical plate 22. This structure optimizes the overall width of the inner box, ensuring efficient use of internal space and contributing to a smaller overall packaging volume.
