ABSTRACT:
A self-adjustable roll-on liquid applicator having enhanced sealing features for containing and dispensing high volatility, low viscosity liquids. The applicator housing defines a discharge opening at its distal end for dispensing of contained liquid therefrom and a liquid-applying ball partially disposed in the housing distal end. An annular valve arrangement is disposed between the distal and proximal ends of the housing, thereby partitioning the housing into a ball retaining chamber and a valve-plug retaining chamber. A valve plug is movable into and out of abutment with an annular projection for regulating liquid flow between the ball retaining and valve-plug retaining chambers. The applicator also includes a spring in axial compressive engagement with the valve plug and ball for normally urging the ball into sealing abutment with a lip portion of the housing.
