[Prior Art] The use of the general airtight check device is based on the anti-reversal device on the hard material, which has a certain airtight effect, such as the "fuel gasification conveyor" of No. 88220495 for steel and plastics. The anti-airtight structure is widely used, and it has a long history, and there is not much change in the structure. Because this structure must be assembled or fabricated with a rigid material structure, it is difficult to use. In the structure of a soft air bag or air bag, the anti-reverse device currently used in the general air bag or air bag structure is mostly provided with a gas-tight cover on the air bag or the read air nozzle. However, the cover structure is easy to fall off due to collision, and it is impossible to effectively achieve the airtight effect. Therefore, some operators have a non-return device on the gas nozzle, and the Qing shirt is only simple. , can not be sure to achieve the effect of airtight; μ, such as the 8321275B tiger "compressive bag structure", its anti-reverse structure is very simple, directly through the venting of the bag body sheet, - anti-reverse ^ This structure is stable Is a difference 'financial creasing or care, the provision of month i.e. the exhaust gas can not be easily opened by the effect of gas-tight. 200951030 In addition, the second paragraph "fourth" and "the packaging bag with the backstop and the manufacturing device of the bag" are bribed, and the backstop structure is also a structural form in which the four pieces are superposed on each other, such a structure. The airtightness also depends on (4) the airtightness of the film_combination degree, and the case of the side number "multi-section central air-tight body" is the effect of airtightness by multi-stage bending and clamping, this bending The structural stability of the clamping is also very limited. For example, the "Air Sealing Body for Strengthening the Side Buffer Function" of the No. 9521_ is also the design of the one-way check valve structure, but the airtight structure (4) is the bag body point. In the structural form of the combination, the airtight stability of the fit is very limited, so it is necessary to improve. "There is another inflated farmer in the case of the vehicle-in-law bag or the inflated structure of the inflatable structure, such as the first leaking and inflating and anti-loose comfortable cap", which is more equipped with a structure that is connected to the inflation valve. And the pipe body is connected, and it is impossible to directly form the relevant anti-reverse structure on the air-clothing; another example is [invention content] Ο There is 1 «The invention of the inventor has been carefully studied and accumulated for many years.
