ABSTRACT:

The apparatus includes a bottle positioning collar that adapts to the base unit of a standard water cooler adjacent where the neck of an inverted water bottle is supported by the base unit. Incorporated within the collar is an ultra-violet lamp assembly, which under control of an electrical supply unit, periodically exposes the water standing in the holding tank to disinfecting ultra-violet radiation. The collar may include a transparent window which may be easily accessed for cleaning when the water bottle has been removed.
