[0002] Fermented pre-prepared food is also called kimchi. The cleaned vegetable raw materials are placed in a jar and then sealed. However, with the improvement of production technology, this special structure of the jar is gradually replaced by a fermentation tank, or sealed by a lid. The sealing performance of the fermentation tank is very high in the process of preparing pre-prepared food, and fermented pre-prepared food also has the phenomenon of fermentation bloating. If the food packaging bottle is only sealed and cannot discharge the fermentation gas, there will be a safety problem of bottle explosion in serious cases; pre-prepared fermented food has another feature, that is, some fermentation gas should be stored in the sealed bottle, which will make the pre-prepared food fresher and chewier. It is required that the sealed packaging bottle cannot have any gas entering, and the fermentation gas generated should be properly stored in the bottle and released only when it reaches a certain pressure, so as to ensure the taste and safety.
