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).
