Abstract
To prevent leakage of the container contents when a child attempts to turn a child-safe closure in the removal direction, the closure is formed with a series of closely spaced detent members at least one of which will abut a detent member on the container to limit turning of the closure in the removal direction to a degree insufficient to allow leakage. Preferably, a series of six closely adjacent radially extending tab like detent members extend outwardly from the skirt wall of the closure within a quadrant of the skirt wall to assure locking by at least the leading or trailing one of the detent members under the worst tolerance conditions. The intermediate detent members become effective for other tolerance conditions which result in the manufacture of the closure and container which are usually made of molded plastic. A simultaneous manual deflection of the closure detent members from their paths of travel for abutting the container detent member and turning of the closure in the removal direction allows the closure to be removed from the container.
