Abstract
An applicator is provided with a flexible container, a discharge passage, a valve seat, and internal springs having first ends attached to one end of a rod that has a valve on its other end. The second ends of the leaf spring are secured to the container. The springs are in an arcuate configuration so as to press the valve into a closed position. Pressure on the flexible container presses on the arcuate shaped springs, straightening them to some degree. Due to the longitudinal increase in the length of the springs, the valve is lifted off of its seat, opening a passage for fluid flow from the container interior through the discharge passage of the applicator nib or pad.
