Description

Technical Field

[0001] The utility model relates to the technical field of cartons, and particularly relates to a multi-layer protection carton. Background Art

[0002] In the modern logistics and transportation industries, the long-distance transportation of goods places higher requirements on packaging materials. Ordinary cartons, due to their single material, often cannot provide sufficient protection and are easily deformed or damaged by external impacts, resulting in damage to the internal items. In addition, during transportation, changes in environmental humidity may also cause the cartons to get damp, thereby weakening their strength and stability.

[0003] The patent with the publication number CN213650238U discloses a packaging carton with multiple interlayers for moisture protection, which solves the disadvantages of single function and resource waste in the prior art. It includes a box body, the box body is a cavity structure, and moisture-proof interlayers, partition layers and drying layers are sequentially fixed to the inner wall of the box body by screws. Both sides of the top of the box body are movably connected with pressing plates through pin shafts, and a cover plate is arranged on the top of the box body. A rectangular positioning groove matching with the pressing plate is opened at the end of the cover plate; through the arrangement of structures such as moisture-proof interlayers, partition layers and drying layers, multiple interlayers are arranged inside the box body. The moisture-proof interlayer is used to absorb moisture, the partition layer is used to isolate the moisture-proof interlayer from the internal drying layer, and the drying layer keeps the internal air dry, and the moisture-proof effect is good.

[0004] When the above-mentioned cartons in the prior art are used, although a certain moisture-proof effect is achieved through the moisture-proof interlayer and the drying layer, during actual transportation, the internal items may still directly collide with the drying layer due to shaking, and there is a deficiency in buffering performance and cannot effectively absorb the impact force generated by the shaking of the items, resulting in the possibility of damage to the items when they are subjected to a large impact. In view of this, we propose a multi-layer protection carton. Summary of the Utility Model
