Abstract A fluid applicator assembly including a retainer ring adapted to be snugly fitted within the open end of a container, the ring having at one end an inwardly extending peripheral web member having a valve opening therein, a cover means secured to the forward end of the retainer, a valve stem extending through the valve opening and having an abutment at one end lying against a cover means for the assembly and a valve head at its other end lying against the underside of the web, and a coil spring urging the valve stem in a forward direction, the wall of the web opening being inclined forwardly so as to define a valve seat and the wall of the web opening being further inclined inwardly so as to permit easy snap-in insertion of the valve stem through the opening.
A fluid applicator assembly comprising a retainer ring having at one end an inwardly extending peripheral web member integrally secured thereto and having an opening therein, a cover secured at said one end and a resilient porous member disposed beneath and in contact with said cover and also secured at said one end, a valve stem disposed in said web member opening and having an abutment at one end in contact with the underside of said resilient porous member and having a conical valve head at its other end in contact with the inner side of said web member, said valve stem also being conical in shape with said conical valve head located at the larger end of said stem, a coil spring disposed between the upper side of said web member and said abutment thereby urging said valve stem in a forward direction, the wall of said web member opening having a surface inclined toward said retainer one end so as to define a valve seat for said conical valve head, said web member wall having also a surface inclined inwardly of said retainer so as to permit an easy snap-in insertion of said valve stem into said web member opening, said larger end of said stem being disposed between said inclined surfaces whereby slight inward movement of said porous resilient cover against the action of said spring serves to move said valve head away from said valve seat to thereby open said web member opening as said larger end is moved slightly inwardly of said web member.

A fluid applicator assembly comprising a retainer ring having at one end an inwardly extending peripheral web member integrally secured thereto and having an opening therein, a cover secured at said one end and a resilient porous member disposed beneath and in contact with said cover and also secured at said one end, a valve stem disposed in said web member opening and having an abutment at one end in contact with the underside of said resilient porous member and having a conical valve head at its other end in contact with the inner side of said web member, said valve stem also being conical in shape with said conical valve head located at the larger end of said stem, a coil spring disposed between the upper side of said web member and said abutment thereby urging said valve stem in a forward direction, the wall of said web member opening having a surface inclined toward said retainer one end so as to define a valve seat for said conical valve head, said web member wall having also a surface inclined inwardly of said retainer so as to permit an easy snap-in insertion of said valve stem into said web member opening, said larger end of said stem being disposed between said inclined surfaces whereby slight inward movement of said porous resilient cover against the action of said spring serves to move said valve head away from said valve seat to thereby open said web member opening as said larger end is moved slightly inwardly of said web member.
Claim 3
Dependent Claim
