ABSTRACT:
A tamper proof cap is set forth including a base for interconnection to a container of pills or the like to be dispensed. An intermediate portion is rotatably mounted between said base and an upper portion said upper portion is keyed for a non-rotating interfitting relationship with respect to said base portion. An integrally formed downwardly projecting tab formed to said upper portion is positioned within a circular groove formed within said intermediate portion. A first channel formed within said base portion communicates with a second channel on said intermediate portion to enable a capsule to be rotatably repositioned to an exit opening within said upper portion. An effort to reintroduce a capsule to said container is precluded due to said positioning of said downwardly projecting tab relative to said first channel ratcheting of said intermediate portion relative to said base portions enabling unidirectional rotation only.
