Technical Field

[0001] The utility model relates to the technical field of cartons, in particular to a moisture-proof and air-permeable carton. Background Art

[0002] Carton is the most widely used packaging product. According to different materials, there are corrugated boxes, single-layer cardboard boxes, etc., with various specifications and models. It can be used for product packaging and transportation, usually as a wrapping material for goods or as an outer layer for protecting items. Ordinary packaging cartons stored in a humid environment can easily cause the items in the carton to get damp, and it is not easy to ventilate when storing items that need ventilation in the carton.

[0003] Existing cartons with moisture-proof and breathable functions have a relatively complex structure, are not easy to mass produce, and have high production costs. For example, the Chinese patent with application number 202123337326.8 discloses an environmentally friendly carton that is moisture-proof and breathable. A moisture-proof box is installed on the lower surface of the box body, and two fixing rods are fixed on the front and back surfaces of the moisture-proof box. A steel sheet roll is fixed on the fixing rod, and a No. 1 rod is installed at one end of the steel sheet roll. A windshield is fixed on the surface of the No. 1 rod.

[0004] For example, the Chinese patent with application number 201820889575.7 discloses a breathable corrugated paper box, wherein a baffle is fixedly installed on the outer surface of the side panel, an upper bottom plate is fixedly installed on the outer surface of the lower end of the side panel, a partition is fixedly installed on the outer surface of the lower end of the upper bottom plate, a lower bottom plate is fixedly installed on the outer surface of the lower end of the partition, a waterproof board is fixedly installed on the outer surface of the lower bottom plate, and a hoop is fixedly installed on the outer surface of the waterproof board.

[0005] Although the above utility model patents can improve the air permeability and moisture-proof performance of cartons, while achieving the air permeability and moisture-proof functions, many other structures are added to ordinary cartons, making the overall structure of the carton complicated, which is not conducive to mass production, and the labor and material costs required for production are also high.

[0006] Therefore, it is necessary to develop a paper box with simple structure, easy mass production, moisture-proof and good air permeability to address the above defects. Utility Model Content
