The apparatus also includes venting through one or more passages offset from the central passage for supplying or discharging air into the storage receptacle as needed, and a filter is included in each vent passage, with the filter being permeable to passage of gases, including air, in either direction through the vent passage, but precluding passage of liquid or solid materials or microorganisms in either direction through the vent passage. The central passage and all venting passages are sealed until use, and the central pass…
