摘要

A roll-on applicator for cosmetics or ball-point pen comprising a ball (4) which fits into a socket (1) at the top of the liquid reservoir, is new. A flexible membrane (5) across the socket supports the ball so that it is normally pressed against the rim (6) of the socket and seals the reservoir, but allows liquid to flow when pressed down.
