[0002] Cartons are an indispensable packaging product in the modern logistics system. They bear important responsibilities such as containing, protecting products and aesthetics. Most cartons are made of corrugated cardboard, which is made by gluing together face paper, lining paper, core paper and corrugated paper processed into corrugated sheets. Cartons are the most widely used packaging product.

[0003] Chinese Patent Authorization Announcement No. CN218752097U discloses a carton with a detachable layered structure, comprising a carton body, a positioning frame, an interlayer cardboard, a limiting frame and an auxiliary slide. The carton body is provided with a positioning frame, and the outer surface of the positioning frame is in contact with and fits against the inner wall of one side of the carton body. The carton with a detachable layered structure is provided with a positioning frame and a limiting contact rod. At the same time, positioning mounting holes are arranged at equal intervals on the side of the positioning frame, so that the interlayer cardboard can be fixed in any position by extending and retracting the limiting contact rod, thereby achieving adjustment of the overall layered space. The above-mentioned prior art solution has the following shortcomings: the carton structure uses a positioning frame, a tension spring, etc. to limit the interlayer cardboard. However, since general cartons are made of corrugated paper, their structural strength is limited. This method increases the manufacturing cost of the carton and cannot guarantee the installation reliability of the positioning frame and the tension spring. Therefore, there is room for improvement.

[0027] The cross section of the guide hole 4 is a vertical strip, and the width of the guide hole 4 is adapted to the width of the airbag 5;

[0028] Specifically, such as Figure 1 、 Figure 3 and Figure 5 As shown, when in use, the airbag 5 and the spring rope 3 are used to fix the air cushion 2 to prevent the air cushion 2 from warping and shaking during transportation. At the same time, the air cushion 2 is used to facilitate the upper and lower layers of the interior of the carton body 1;

[0029] The outer side of the air cushion 2 is installed with a spring rope 3, and one end of the spring rope 3 passes through the outer side of the guide hole 4, and the outer end of the spring rope 3 is installed with an air bag 5;

[0030] The cross section of the airbag 5 is in the shape of an elongated strip, and the cross sections of the airbag 5 and the guide hole 4 are distributed in a cross shape;

[0031] Specifically, such as Figure 1 、 Figure 3 As shown, when in use, the spring rope 3 is tightened to ensure the stability of the airbag 5, so that the airbag 5 forms a protection for the outside of the carton body 1;

[0032] One side of the airbag 5 is against the outer wall of the carton body 1, a top cover 7 is installed on one side of the top of the carton body 1, and a folding cover 8 is installed on one side of the top cover 7;

[0033] The inner sides of the side cover 6, top cover 7 and folding cover 8 are all provided with secondary folds 9, and the distance between each secondary fold 9 and each fold is the same;

[0034] The outer sides of the side covers 6 are each installed with a soft surface sticker 10, the inner wall of the top cover 7 is installed with a first sticky surface sticker 11, and the inner wall of the top cover 7 above the first sticky surface sticker 11 is installed with a second sticky surface sticker 12;

[0035] After the soft surface sticker 10 is folded inward, the first adhesive surface sticker 11 and the soft surface sticker 10 are adhered to each other. After the soft surface sticker 10 is folded at a right angle, the first adhesive surface sticker 11 and the second adhesive surface sticker 12 are adhered to each other.

[0036] The top of the carton body 1 on both sides of the top cover 7 is installed with a side cover 6, the outer side of the folding cover 8 is installed with a second magnet 14, and the top of the outer wall of the carton body 1 is evenly installed with a first magnet 13, and the positions of the first magnet 13 and the second magnet 14 correspond to each other, and the first magnet 13 and the second magnet 14 attract each other;

[0037] Specifically, such as Figure 1 、 Figure 2 and Figure 4 As shown, when in use, the secondary fold 9 is utilized to adjust the sealing height of the top of the carton body 1, thereby increasing the storage space inside the carton body 1, and with the cooperation of the side cover 6, the first adhesive label 11 and the second adhesive label 12, the side cover 6 and the top cover 7 are connected and fixed to ensure the reliability of the seal, thereby reducing the possibility of items spilling.

[0038] Working principle: When the utility model is in use, first rotate the airbag 5 on one side 90 degrees, and then move the airbag 5 through the guide hole 4 to the inside of the carton body 1, and then lift one side of the air cushion 2 to facilitate the placement of items under the air cushion 2. After the airbag 5 is passed through the guide hole 4 again, the air cushion 2 can be moved up and down by utilizing the guiding effect of the guide hole 4, so that the air cushion 2 can meet the requirements of covering items of different capacities below, thereby facilitating the placement of another item on top of the air cushion 2 to achieve layered storage of two items.

[0039] Secondly, the spring rope 3 is tightened to make the airbag 5 close to the outer wall of the carton body 1, and then the position of the airbag 5 is fixed. The elastic deformation of the airbag 5 is used to isolate the four sides of the carton body 1. When multiple carton bodies 1 are arranged, the mutual collision strength between the carton bodies 1 is reduced, so as to provide a certain anti-collision protection effect for the items inside.

[0040] Finally, after folding the side cover 6 inward, the top cover 7 is covered on a certain tube of the side cover 6, so that the first sticky surface sticker 11 and the soft surface sticker 10 are adhered to each other, and then the folding cover 8 is inserted into the interior of the carton body 1, so that the second magnet 14 and the first magnet 13 attract each other, so that the folding cover 8 is tightly attached to the inner wall of the carton body 1 to achieve sealing of the carton body 1. At the same time, the effect of the secondary fold 9 can be utilized so that after the side cover 6, the top cover 7, and the folding cover 8 are folded along the secondary fold 9, the overall sealing height of the carton body 1 is increased to increase the storage space of the carton body 1. At the same time, the adhesion between the side cover 6 and the second sticky surface sticker 12 is utilized to improve the sealing effect and prevent items from overflowing.
