ABSTRACT:
A douche or enema dispenser is provided as a unitary hermetically sealed container and a cooperating overcap. The container has a cap structure which is removable by torsion applied through the overcap positioned over the cap structure, engageable with the adjacent container neck portion, and simultaneously rotatable as well as axially movable relative thereto. As the overcap is rotated relative to the neck portion, ribs in the overcap engage tip portions of a wing member associated with the cap structure. Since the cap structure is mounted over and sealed about a frangible web located around the container mouth that is located at the distal end of the neck portion, when sufficient torsion develops, the web is fractured, the cap is removed, and the container is opened. In opening the container, force upon walls of the liquid-filled body portion of the container is minimized.
