ABSTRACT:
A fluid applicator includes a coating implement, an elastic closure cap, and a stopper for use with a fluid container. The elastic closure cap includes an enlarged irregular sealing rib on a skirt that is force-fit into the stopper, creating a resilient force on a sealing lip that contacts a seat on the stopper. Inverting the container and pressing on the coating implement, presses the elastic closure cap, deforming it to move the sealing lip off of its seat on the stopper to allow fluid flow from the container, through the stopper and elastic closure cap, to the coating implement.
