Abstract
A valve (100) includes a base (110) defining a central axis (114). The valve (100) includes a post (118) connected to the base (110) and extending axially outwardly from the base (110), in the direction along the central axis (114). The valve (100) includes at least one flow aperture (122) in one or both of the base (110) and/or the post (118). The valve (100) further includes a flexible membrane (126) having an orifice (130) and having a non-dispensing configuration wherein the orifice (130) is located proximate to the post (118) to minimize communication through the valve (100). The flexible membrane (126) has a dispensing configuration wherein the orifice (130) is moved away from the post (118) for establishing communication through the valve (100).
Claims24
A valve to permit selective communication therethrough, said valve comprising:
- a base defining a central axis;
- a post connected to said base;
- at least one flow aperture in said base and/or said post;
- and
- a flexible membrane having an orifice and having a non-dispensing configuration wherein said orifice is located proximate to said post to minimize communication through said valve, and said flexible membrane having a dispensing configuration wherein said orifice is moved away from said post for establishing communication through said valve, wherein said flexible membrane includes a peripheral wall for sealing against a portion of said base and a transverse wall extending inwardly of said peripheral wall and defining said orifice, and said peripheral wall defines a top end and a bottom end, wherein said transverse wall extends from said bottom end and is located axially inwardly of said top end with said flexible membrane in said non-dispensing configuration, relative to said central axis.
A valve to permit selective communication therethrough, said valve comprising:
- a base defining a central axis;
- a post connected to said base;
- at least one flow aperture in said base and/or said post;
- and
- a flexible membrane having an orifice and having a non-dispensing configuration wherein said orifice is located proximate to said post to minimize communication through said valve, and said flexible membrane having a dispensing configuration wherein said orifice is moved away from said post for establishing communication through said valve;
- wherein said flexible membrane does not contact, and is spaced axially outwardly from, a distal end of said post with said flexible membrane in said non-dispensing configuration.
A valve to permit selective communication therethrough, said valve comprising:
- a base defining a central axis;
- a post connected to said base;
- at least one flow aperture in said base and/or said post;
- and
- a flexible membrane having an orifice and having a non-dispensing configuration wherein said orifice is located proximate to said post to minimize communication through said valve, and said flexible membrane having a dispensing configuration wherein said orifice is moved away from said post for establishing communication through said valve;
- wherein said base includes an outer wall surrounding said post, said outer wall includes a flange extending laterally outwardly therefrom, said flange includes a channel to accommodate movement of said flexible membrane relative to said base.
