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.

1-41. (canceled)
A dispensing assembly adapted to mount on a neck finish of a container to control discharge of a product stored in a body of the container to surroundings outside of the container through a container mouth established by the neck finish along a longitudinal axis of the container, the dispensing assembly comprising
- a base adapted to mount to the neck finish of the container, the base including a deck, an opening wall extending inward in an axial direction from the deck toward the body of the container around a dispensing opening arranged to receive product discharged from the container through the neck finish, and an annular wall extending inward in the axial direction along the longitudinal axis from an undersurface of the deck toward the body of the container, and
- a dispensing valve coupled to the base to lie in the dispensing opening, the dispensing valve including an opening portion adapted to allow product to be dispensed through the dispensing valve, a mounting portion adapted to mate with the base, and an isolating portion extending outward from the longitudinal axis in a radial direction from the opening portion to the mounting portion to couple the opening portion to the mounting portion for movement relative thereto so that radial forces on the mounting portion induced by a user squeezing the container causing distortion of the mounting portion are absorbed by the isolating portion rather than being transmitted to the opening portion thereby reducing distortion of the opening portion when a user squeezes the container to dispense product in the container, and
- wherein the annular wall of the base includes a main portion surrounding an outer diameter of the mounting portion of the dispensing valve and a crimped portion extending inward in the radial direction from the main portion of the annular wall toward the longitudinal axis of the container, a portion of the deck is arranged to extend above and mate with a topside of the mounting portion of the dispensing valve, and the crimped portion of the annular wall is arranged to extend under and mate with an underside of the mounting portion of the dispensing valve so that the mounting portion of the dispensing valve is blocked from movement outward and inward in the axial direction relative to the deck when the dispensing valve is coupled to the base.

- wherein the annular wall includes crimped means for trapping the mounting portion of the dispensing valve in a stationary position relative to the deck of the base.
