A system for dispensing fluid from a container. The container is pressurized by supplying gas into the container thereby forcing the fluid out of the container through a siphon tube and an outlet valve in the container. The system utilizes a valve assembly having two valves, one for enabling the flow of the gas into the container and the second for allowing the flow of the fluid out of the container. The valve assembly is mounted in a neck member that is secured to an opening in one of the walls of the container. Arranged within the neck is a deformable seal that is compressed between a body portion of the valve assembly and an inner surface of the neck member. A non-threaded retaining ring holds the valve body portion of the valve assembly within the neck member and serves to apply the force to the valve body portion for compressing the seal. In order to avoid the existence of a sump within the valve structure, which could damage or contaminate the fluid dispensed from the container, the top of the valve assembly is substantially flush with the top of the neck member. A coupler is connected to the neck member and has a probe capable of being moved between an open position and a closed position. In its open position, the probe serves to open the two valves of the valve assembly for enabling gas to be fed into the container and fluid to be dispensed from the container.

A fluid dispensing assembly comprising: a container for holding the fluid; a valve assembly for providing access to fluid within said container and having valves therein, said valve assembly having a body portion with a seal engaging surface; valve assembly receiving means for securing said valve assembly to said container, said receiving means including a deformable seal member and non-threaded means for deforming said seal member between said seal engaging surface of said valve assembly and said receiving member without a need for substantial rotational movement, said non-threaded deforming means being releasably secured within said receiving means at a predetermined position relative to said valve body portion for preventing overcompression of said seal member when said seal member is in engagement with said seal engaging surface, said valve assembly being arranged within said receiving means such that the upper ends of both said valve assembly and said receiving means are substantially flush when said valves of said valve assembly are in a closed position in order to avoid the existence of a sump in the upper end of such arrangement; and a coupler including: grasping members for grasping said valve assembly receiving means around its outer peripheral edge for securing said coupler to said valve assembly receiving means; a coupler body having a side fitting extending therefrom coupled to a first passage within said coupler body; a probe member movable within said coupler body, said probe member having an end fitting connected to one end and defining a passageway therethrough in communication with said end fitting; and said probe member being movable within said coupler body between an open and a closed position whereby in said open position said coupler opens said valves of said valve assembly and connects said passages in said coupler to said open valves and in said closed position said coupler closes said valves of said valve assembly.
