Abstract
Flow control apparatus is provided for reducing the pressure on a liquid as it flows from a container where it is maintained at a relatively high pressure to a dispensing valve member where the liquid is dispensed at a relatively low pressure wherein the flow control apparatus comprises a hollow housing, a hollow core member and a flow regulator which are assembled to be in a relatively fixed relationship and to provide a gradually increasing cross-sectional area between the flow regulator and the hollow core member and the hollow housing to reduce the pressure on the liquid. Also, closure members are disclosed and have displaceable sealing portions that may be displaced by a displacing member when attaching a dispensing valve to the container so that the liquid may be displaced from the container.
