Patent ID: 8397958

Claim:
A closure assembly for a container comprising: a housing having two coaxially disposed and radially-spaced, generally-cylindrical walls extending axially away from a top wall surface to define an annular chamber therebetween and including, namely, a first annular wall and a second annular wall disposed within the first annular wall, an inner surface of the second annular wall defining a first fluid passage having a fluid inlet and a fluid outlet, the inner surface of the second annular wall having a retaining ring receiving surface, and a first valve receiving surface spaced axially from the retaining ring receiving surface, the retaining ring receiving surface having a first annular protuberance extending radially inwardly from the inner surface into the first fluid passage and a detent spaced axially from the protuberance and extending radially outwardly; a retaining ring having a peripheral connection portion disposed about a second fluid passage, the connection portion being in cooperative engagement with the retaining ring receiving surface, the connection portion having an axially outwardly extending annular flange positioned in the detent, the annular flange having opposed first and second opposed surfaces with a third cylindrical wall extending from the first surface and a fourth cylindrical wall extending from the second surface, the third cylindrical wall has an outer surface abutting an outer surface of the first annular protuberance, and the fourth cylindrical wall having a second valve receiving surface; and a valve disposed in the first fluid passage and sealing the first fluid passage, the valve having opposed surfaces having a retaining ring mating surface extending from a first surface and in cooperative engagement with the second valve receiving surface and a housing mating surface extending from a second surface opposed to the first surface and cooperatively engaging the first valve receiving surface.
