Valve assembly and coupler therefor

摘要

An improved coupler or tapping mechanism and valve system for obtaining access to a container of fluid. In a container of fluid, and particularly a keg for beer, a valve assembly receiving member or keg neck extends from the top of the container. This keg neck receives a flat top, dual valve system which is operated by the coupler. The improved coupler is placed over the keg neck and is positively secured thereto and sealed relative to the valve assembly by a two point locking mechanism which engages the external surfaces of the keg neck. A safety locking mechanism is provided which prevents removal of the coupler from the keg neck as long as the dual valves are in an open fluid tapping position.
