Design does not depend on specific liner materials or configurations. Unique venting channels are said to allow internal pressures, both positive and negative, to be relieved. Technology can be incorporated into closures, orifice reducers, and sleeved inserts. Also recommended to accommodate the expansion caused by fermenting food products.
