[0005] To achieve the above objectives, this utility model provides the following technical solution: a foldable, flat, and collapsible corrugated cardboard box, comprising a box body, a bottom cardboard, side cardboard, and a front cardboard. The front cardboard is fixed at the front and rear positions of the top of the bottom cardboard, and the side cardboard is fixed at both sides of the top of the bottom cardboard. The bottom cardboard, side cardboard, and front cardboard together surround and form the box body. A bendable and foldable end is formed at the middle position of the side cardboard and the front cardboard. A second cover plate is connected to the top of the left side cardboard, and a first cover plate is connected to the top of the right side cardboard. An iron sheet is fixed in the second cover plate, and a magnetic block is fixed in the first cover plate.

[0006] As a further technical solution of this utility model, the front cardboard is symmetrically distributed about the central axis of the bottom cardboard, and the side cardboard is symmetrically distributed about the central axis of the bottom cardboard.

[0007] As a further technical solution of this utility model, a flexible bending plate is provided at the connection between the bottom cardboard and the side cardboard, and a flexible bending plate is provided at the connection between the bottom cardboard and the front cardboard.

[0008] As a further technical solution of this utility model, a bent plate is designed at the connection between the side cardboard and the first cover plate, and a bent plate is designed at the connection between the side cardboard and the second cover plate.

[0009] As a further technical solution of this utility model, the iron sheet and the magnetic block form a magnetic adsorption, and the parallel height position of the first cover plate is lower than the parallel height of the second cover plate.

[0010] As a further technical solution of this utility model, the outer wall of the bottom cardboard is coated with a waterproof layer, and the outer walls of the side cardboard and the front cardboard are coated with a wear-resistant layer.

[0011] As a further technical solution of this utility model, a reinforcing core board is fixed in the middle position of the bottom cardboard, and corrugated core layers are fixed at the upper and lower positions of the reinforcing core board.

[0012] As a further technical solution of this utility model, a water-proof layer is fixed to the outside of the corrugated core layer, and the corrugated core layer is symmetrically distributed about the central axis of the reinforcing core plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: this kind of foldable flat storage snap-fit ​​corrugated cardboard box not only improves the folding and storage capacity, but also improves the strength and snap-fit ​​effect of the corrugated cardboard box.

[0014] (1) The carton body is formed by using the bottom cardboard, side cardboard and front cardboard together. A flexible and foldable end is formed in the middle of the side cardboard and the front cardboard. A flexible bending plate is set at the connection between the bottom cardboard and the side cardboard. A flexible bending plate is set at the connection between the bottom cardboard and the front cardboard. Therefore, when the carton body is folded and stored, the foldable end is folded inward. The top layer of the carton body is folded downward. Based on the flexible design of each connection, it is convenient to compress and fold the carton body as a whole, so that it tends to be flat, thereby improving the overall storage capacity.

[0015] (2) A reinforcing core board is arranged in the middle of the bottom cardboard to reinforce the middle position. Corrugated core layers are arranged above and below the reinforcing core board to further improve the overall strength. A waterproof layer is arranged at the outermost top and bottom of the bottom cardboard to improve the waterproofing capacity and enhance the strength and waterproofing effect.

[0016] (3) A section of bent plate is designed at the connection between the side cardboard and the first cover plate, and a section of bent plate is designed at the connection between the side cardboard and the second cover plate. Therefore, when the top is closed, both the first cover plate and the second cover plate can be bent inward, and the parallel height of the first cover plate is lower than the parallel height of the second cover plate. Therefore, after bending, the first cover plate is located below the second cover plate. At this time, the iron sheet and the magnetic block form magnetic adsorption, achieving the purpose of fastening, thereby improving the overall fastening effect. Attached Figure Description
