Problems solved by technology

[0003] Take the utility model patent No. CN204580206U of the People's Republic of China as an example for a buoy waterproof bag. The buoy waterproof bag uses two pieces of sandwich cloth as the base material. PVC is then laminated to become the buoy waterproof bag, but although the PVC layer on the mesh cloth can be waterproof, it has the problem of poor coloring effect, so it is not easy to print exquisite and bright patterns
In addition, products made of PVC are toxic and not environmentally friendly, and are not suitable for prolonged contact with the human body

Abstract

A buoy waterproof bag comprises two sheets and an air nozzle unit. The sheets are interconnected and cooperate to define a storage space, each sheet includes an inner inside layer, and an outer layerstructure arranged on the outer side of the inner inside layer, the outer layer structure has an inner layer and an outer layer, at least one of the outer layer structures of the sheet further has a pattern layer disposed on the outer surface of the outer layer, the material of the inner inside layer and the material of the inner layer are thermoplastic polyurethane, the outer layer is made of polyester, at least one sheet of which is hermetically connected between the inner layer and the outer layer structure to form a first sealing portion and a second sealing portion, and the inner layer ofthe at least one sheet of which cooperates with the inner layer of the outer layer structure to define an air chamber sealed around by the first sealing portion and the second sealing portion.

Description

technical field [0001] The invention relates to a waterproof bag, in particular to a buoy waterproof bag. Background technique [0002] The existing buoy waterproof bag allows the user to hang it on the body when entering the water. In addition to the functions of lifesaving and warning, the user can also put his personal belongings into the bag, which is convenient for storage and will not be lost. It has a storage function, so it is generally loved by consumers. [0003] Take the utility model patent No. CN204580206U of the People's Republic of China as an example for a buoy waterproof bag. The buoy waterproof bag uses two pieces of sandwich cloth as the base material. PVC, then, is laminated and becomes this buoy waterproof bag again, only, though the PVC layer on the described sandwich cloth can be waterproof, the problem of poor coloring effect is arranged, so, be difficult for printing exquisite bright and beautiful pattern. In addition, products made of PVC are toxi...
