ABSTRACT:
A tamper-proof cap for a container closure device for providing a visual indication of any tampering and tampering attempts with the container closure device includes an annular body portion, a pull ring portion detachably joined to the annular body portion, a tear-out strip portion joined to the pull ring portion and a pair of connecting membranes disposed between the tear-out strip portion and the annular body portion. The annular body portion includes an enclosing wall, an inwardly extending lid section joined to a top edge of the enclosing wall, and an outwardly extending lip section joined to a second opposite edge of the enclosing wall. The inwardly extending lid section is annular in shape and defines a center opening. The pull ring portion is detachably joined to the inner edge of this center opening by three reduced-thickness membrane sections which can be easily torn under nominal manual force. The connection between the pull ring portion and the tear-out strip portion remains intact, yet as additional force is applied upwardly and outwardly on the pull ring portion in the direction of this tear-out strip portion, the connecting membranes begin to tear thereby separating the tear-out strip portion from the remainder of the annular body portion. Once this strip portion is completely removed, the annular body portion is severed and it is then able to be manually removed from its secured position beneath the anchor ring which secures the closure device to the container.
