Abstract
Abstract A water cooler is provided for use with bottled drinking water. Each bottle is provided with an inverted valve cap so that the water is released directly from the bottle to a cup or other container. The unit includes a housing having an upper chamber adapted to receive the bottle and support it in an inverted position. Cooling coils are mounted within the upper chamber for direct engagement with the bottle placed therein. A pressuresensitive switch is located to engage the bottle and is kept closed by the weight of the filled bottle. When the bottle empties the switch opens to shut off the refrigeration system.
