Inner cover of pickle bottle

Technical Field

The utility model relates to the technical field of pickle equipment, in particular to an inner cover of a pickle bottle.

Background

The pickle bottle is a common device for pickling vegetables such as various pickled Chinese cabbages and is widely applied to the field of various pickled foods. When pickled Chinese sauerkraut is pickled, water is added into a water tank at the opening of a jar, and the jar cover is buckled to isolate the outside air and prevent the invasion of microorganisms. But the pickle can generate gas in the fermentation process, so that the air pressure in the jar is increased, and the pickling quality is influenced. The traditional exhaust mode is that gas pushes the cover through the gas so that the gas can be exhausted through the water tank in the form of bubbles, but the exhaust mode easily causes the water tightness in the water tank to be reduced and even enters the jar in the process of pushing the cover, and the water quality in the jar is influenced.
