Abstract
A ball type roll-on liquid dispenser provided with a generally spherical ball and relatively small supporting nibs supporting the ball for rotation. A restricted passageway is provided between the ball and neck of the container to meter the liquid contents of the container. A thin retaining ring for retaining the ball is also provided as well as a closure liner adapted to apply variable pressure to the thin retaining ring to control the flow of liquid from the container and to completely seal the container from the atmosphere.
