Abstract
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 cl…
