Abstract
A dispensing valve includes a resiliently flexible mounting portion, a resiliently flexible opening portion disposed radially inwardly of the mounting portion, and a resiliently flexible isolating portion disposed radially between and coupled to the mounting and opening portions. The isolating portion extends both radially outwardly and axially to form a first radial space between the opening and isolating portions, and is spaced radially inwardly of the mounting portion to form a second radial space between the mounting and isolating portions. The opening portion may include one or more slits.
