The neck of the traditional pickle jar is relatively short. Due to the influence of temperature and pressure, the dirty water along the jar edge will be sucked into the jar, polluting the pickle, and in severe cases, the pickle will deteriorate. This phenomenon is particularly prominent in urban architecture. The mouth of the pickle jar with high neck is high, so the dirty water along the jar edge cannot be sucked into the pickle jar. Its advantages and principles are here, and it has won the national utility model patent.
