Inflating closer

Abstract

The invention relates to a small bulk, highly sealed charge closer manufacturing technical solution, for reducing its bulk to the minimum and saving production and manufacturing costs and giving it larger use space and range. As compared with the existing charge closers, it has the following beneficial effects of: (1) simple structure: composed only of peripheral module and central module, simple in structure and easy to manufacture; (2) small bulk: able to be widely applied to various advanced, sophisticated and fine charge container products; (3) reliable closing: the higher the internal gas pressure is, the more obvious the closing effect is; in addition, and it can be widely applied to sport balls, sport airbeds, automobile tyres, airship chambers, and other gas compression containers.

Description

Technical field [0001] The invention relates to an inflatable closure device, which is an inflatable closure technical solution with compact size and high performance made of elastic plastic materials, and the formed product can be widely used in sports balls, sports air cushions, automobile tires, spaceship airbags, Gas compression containers such as anti-collision airbags, floating lifesaving, children's toys, etc. Background technique [0002] At present, some known inflatable closing devices (such as automobile tire inflatable closers) are generally composed of sleeves, pistons, springs and other components. Gas leakage function; but the structure is relatively complicated, the volume is large, and the scope of use is limited; other known inflatable closing devices (such as children's inflatable toys) are simply composed of two parts: an inflation port and a plastic plug. Once plugged into the inflation port, the inflation and closure process is completed. Although the ...

[0002] At present, some known inflatable closing devices (such as automobile tire inflatable closers) are generally composed of sleeves, pistons, springs and other components. Gas leakage function; but the structure is relatively complicated, the volume is large, and the scope of use is limited; other known inflatable closing devices (such as children's inflatable toys) are simply composed of two parts: an inflation port and a plastic plug. Once plugged into the inflation port, the inflation and closure process is completed. Although the structure is simple, the inflation and closure effects are extremely limited, and it cannot withstand a slightly larger air pressure at all.
