ABSTRACT:
A fluid dispensing closure includes a closure base having a deck, a skirt for securement to a container finish and a recess in the deck. The recess includes a first annular wall extending from the deck within the skirt, a second annular wall extending radially inwardly from the first annular wall at a position spaced from the deck, and a third annular wall extending toward the deck from an inner periphery of the second annular wall. A dispensing valve of flexible resilient elastomeric construction has a peripheral portion captured in compression between a collar and the third annular wall, and a concave central portion with at least one dispensing slit. In the preferred embodiment, the collar includes a flat annular deck, and a first annular wall extending from an outer periphery of the flat annular deck and engaging the third annular wall on the base to secure the collar and the valve to the base such that the outer surface of the annular deck of the collar is flush with the outer surface of the deck of the closure base.
