Claim 1

A fluid applicator comprising a retainer ring having a projecting portion, a cover secured to said ring, said ring having an opening therein, a valve seat surrounding said opening, a valve assembly of inverted wine-cup shape and including a valve head and a flexible resilient cup engageable with said valve seat to control flow through said opening, the lowermost end of said cup being secured to said projecting portion, said cup being provided with at least one aperture through the lower side wall thereof, said lower side wall normally engaging said projecting portion to prevent fluid flow through said aperture, and a resilient porous body disposed between said cover and said ring, said body being deformable so that said cover may be depressed urging a portion of said body toward said opening to depress said cup away from said valve seat and to spring said lower side wall away from said projecting portion to permit fluid flow through said aperture and said opening, said cover holding said body under slight compression to maintain said lower side wall against said projecting portion.
