Water bottle system for use in a dental operatory

摘要

A water bottle adapter (6) fits securely onto a water bottle (1) which is used to isolate the water within the bottle from a common water supply. The adapter (6) is fastened to a mating device by means of a threaded neck (7). The neck (7) includes two longitudinal tensioning ribs (37) that promote a retaining function between the neck (7) and any device that has been affixed to the neck (7). A pressure relief valve (13) having a valve stem (14) is formed within the lid (8) of the adapter (6) to permit the escape of air from the bottle (1) when in use. A series of ribs (19) is formed within a bore containing the valve stem (14) to dampen noise produced by the operation of the valve (13).
