Patent ID: 7467907

Claim:
A liquid applicator comprising: a flexible reservoir for accommodating liquid, the reservoir comprising an open end connected to a ferrule with a valve assembly disposed therebetween, the valve assembly comprising a collar comprising a proximal end facing the reservoir and a distal end facing the ferrule, the collar comprising a stepped passageway providing communication between the reservoir and the ferrule, the stepped passageway having a narrow middle portion between the proximal and distal ends of the collar, the proximal end of the collar receiving a valve member and a retainer with the valve member trapped between the retainer and the narrow middle portion of the collar; and the distal end of the collar receives a pin seal, the pin seal comprising a shaft comprising a solid proximal end directed towards the reservoir and a distal end directed towards the ferrule, the distal end of the shaft comprising an axial slot, the distal end of the shaft of the pin seal is connected to a flange that is accommodated in the distal end of the collar, wherein the pin seal is movable between a closed position with proximal end of the shaft being disposed in the narrow middle portion of the stepped passageway and blocking flow therethrough and an open position where at least a portion of the axial slot is disposed in the narrow middle portion of the stepped passageway thereby permitting restricted flow therethrough.
