Abstract
A stored liquid dispensing applicator includes a valving arrangement formed of a valve seat and a spring-driven shuttle that is disposed for axial displacement into and out of valve-defining abutment and engagement with the valve seat. The shuttle is displaceable between distal and proximal limits of travel that include a first position defining the distal limit and a second position proximally spaced from the distal limit and distally spaced from the proximal limit. The valve seat is arranged for contact with the shuttle uninterruptedly between the first and second positions to close the valve, and for spaced apart relation with the shuttle between the second position and the proximal limit of travel to open the valve for dispensing of stored liquid.
