Abstract
Abstract A dispensing device is disclosed which includes a connector valve (19) and a diaphragmic container valve (41) that permits a fluid dispensing passageway to be connected to a disposable container of fluid in a simple, efficient manner to provide continuous fluid flow. The connector valve (19) engages the container valve (41) to simultaneously open both the container valve (41) and the connector valve (19) in a single connecting step to dispense fluid from the container into the dispensing passageway. Upon disengagement of the valves, both valves simultaneously close. The assembly is simple, lightweight and inexpensive, thereby being particularly suitable for use with lightweight disposable fluid containers.
