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.

Flow control apparatus for use in dispensing a liquid from a container at a relatively low pressure wherein the liquid in the container is under relatively high pressure comprising: a hollow housing having a main body portion; mounting means for mounting said hollow housing on said container so that said fluid may flow therethrough; an integral valve attaching portion located on one side of said main body portion; said integral valve attaching portion having a passageway extending therethrough for permitting said liquid to flow therethrough; said main body portion having a generally cylindrical inner surface; said main body portion having an abutment surface extending between said generally cylindrical inner surface and said passageway; a dispensing valve member secured on said valve attaching portion; a hollow core member having a front end portion mounted in said main body portion and an integral back end portion projecting toward said container; said front end portion having a continuous cylindrical inner surface; said back end portion having a continuous inner surface having a first part having a cylindrical surface having the same diameter as said cylindrical surface of said front end portion and a second part having a conical inner surface; said back end portion having an open end to provide a passageway for said liquid in said container; a flow regulator located within said hollow core member; abutment means on said flow regulator for contacting said abutment surface of said main body portion; said flow regulator having an outer surface having a cross-sectional configuration that is slightly smaller than facing portions of said continuous inner surfaces of said hollow core member; said outer surface having a central portion that is cylindrical and an adjoining portion that is conical; spacing means for providing a spaced relationship between said inner and outer surfaces for permitting the flow of said liquid from said container through said spaced relationship and said hollow housing to said valve member comprising a first plurality of circumferentially spaced apart protuberances projecting outwardly from said conical outer surface and in contact with portions of said conical inner surface; and a second plurality of circumferentially spaced apart protuberances projecting outwardly from said adjoining portion and in contact with portions of said cylindrical inner surface; and connecting means for connecting said hollow housing, said hollow core member and said flow regulator in a fixed relationship with said abutment means in contact with said abutment surface and said first plurality of circumferentially spaced apart protuberances in contact with said conical inner surface.
