Abstract
Abstract A combination sealing, venting, mounting and filter element is positioned between a replaceable inverted water bottle and a water reservoir from which the water is dispensed. The element is snugly fitted within the mouth portion of the reservoir or olla of plastic material into which a dispensing valve is threaded. The element includes a venting channel in communication with a filter housing which is releasably secured to such element adjacent to an upwardly extending flange portion, the flanged portion being apertured for venting and also shaped to provide a sealing portion engaging the bottle. Also the element has a downwardly extending portion near its periphery for engagement of a flat surface of a housing for the reservoir.
