ABSTRACT:
A rotatable member is held within a closure cap by a circumferential ridge. Both the closure cap and the rotatable member carry inwardly projecting studs. Ribs on stepped cylindrical surfaces of the container neck are provided with channels that permit axial passage of the studs when properly aligned. Proper alignment is achieved by means of stops on the rotatable member and the closure cap which, when engaged during rotation, align the studs circumferentially with the channels. The rotatable member is provided with a frictional fit on the neck of the container, or the rib thereof, so that as the closure cap is rotated, the rotatable member will stay in position on the container neck until the stops contact one another. When the closure cap is rotated in a predetermined direction to a predetermined point, it will cause the stops to contact such as to properly index the studs on the rotatable member relative to channels in a rib on the container neck. Thereafter, rotating the closure cap in the opposite direction to a point which may be determined by markings on the container and the closure cap will cause the studs on the closure cap to be aligned with the channels in a second rib on the container neck so that the closure cap can be removed from the container.
