Abstract: An improved mounting adapter is provided for use in a bottled water cooler of the type having an upwardly open cooler reservoir for receiving a supply of water from a bottle mounted over the reservoir in an inverted orientation to permit water downflow from the bottle to the reservoir. The improved adapter includes a compact and substantially unitized adapter body or shell for removable snap-fit mounting onto the cooler reservoir at the open upper end thereof. The adapter additionally includes an upstanding feed tube or probe for operatively engaging a valved bottle cap mounted on the neck of a water-containing bottle supported in an inverted orientation over the cooler reservoir. In one form, the adapter may carry a seal ring gasket for sealingly engaging an inner wall surface of the cooler reservoir, and an air filter may be provided to filter ambient air drawn into the reservoir.

Abstract: A mounting adapter and related bottle cap are provided for use in a bottled water cooler having an upwardly open reservoir for receiving a supply of water from a bottle mounted over the reservoir in an inverted orientation to permit water downflow from the bottle to the reservoir. The mounting adapter comprises a compact housing for press-fit installation into an upper region of the reservoir, wherein the adapter housing carries an outer seal ring for sealing engagement with an inner wall surface of the reservoir. An upstanding feed tube or probe carried by the adapter housing includes separate air and water flow passages as described in U.S. Pat. No. 5,413,152, and has an upper tip end shaped for opening and closing a valved bottle cap mounted on the neck of a water-containing bottle supported in an inverted position over the reservoir. The bottle cap may be constructed, e.g., according to U.S. Pat. No.
