ABSTRACT:
An applicator for applying a liquid composition to a work surface. The applicator includes a bottle, a cap detachably mounted on a neck projecting from the bottle and a cover that extends over the cap and an upper portion of the bottle. The cap has and inclined surface with a multi-layer polishing pad mounted thereon. The pad has a cloth outer layer overlying a compressible, preferably foam, under layer. The pad has a central aperture exposing the end of a valve stem. Pressing the pad against the work surface opens a normally closed valve dispensing the liquid in the bottle onto work surface. The valve stem moves reciprocally along a path generally perpendicular an inclined surface on the cap on which the pad is mounted.
