ABSTRACT:
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. The keg neck receives a dual valve system which is operated by the coupler. The improved coupler is placed over the keg neck and is positively secured thereto by a three 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.
