A container for use in combination with a closure has a threaded neck and a flexible lip portion which extends inwardly and upwardly from the top of the neck portion and which defines the opening to the container. The closure has a top portion from which depends a threaded annular skirt which cooperates with the threaded neck portion. The upper surface of the threads on the annular skirt have a plurality of radially extending small upwardly pointed ribs defining fastening configurations registrable with a plurality of radially extending small downwardly pointed ribs on the lower surfaces of the thread on the neck portion of the container. The threads of the closure are smaller than the threads on the neck of the container so as to extend a lesser distance toward the neck of the container than the distance the thread on the neck of the container extends toward the closure. A flexible annular ring is attached to the closure by a plurality of radially extending frangible elements has a plurality of circumferentially spaced radially inwardly extending angular projections arranged for registry with a ratchet section on the neck portion of the container when the closure and ring are rotated in one direction and so formed as to prevent rotation of said annular ring in the opposite direction without removal to indicate tampering with the closure.
