A tamper indicating closure for a container comprising a threaded cap to which is attached an indicator ring. The indicator ring has a radially inward lower flange that slips into locking engagement with a flange on the neck of the container as the closure is applied to the container. As the closure is removed from the container, the indicator ring is severed along weakened portions so that the lower portion of the indicator ring drops clear of the closure thus providing an indication the closure has been rotated in a direction for its removal from the container.

A tamper indicating package comprising a container with a threaded neck finish and a retaining ring interdisposed between said threaded portion and the body of the container, an internally threaded skirted closure compatable with the threads on said finish, a tamper indicating ring in telescopic arrangement with and fastened to the extremity of said closure skirt so that there is circumferential contact between said closure extremity and said tamper indicating ring, said tamper indicating ring comprised of first and second sections with frangible means interdisposed between said sections and wherein a portion of each of said sections abuts against said extremity of said closure skirt so that an axial force can be transmitted to said ring to cause a frusto-conical portion thereof to lodge beneath said container retaining ring, and when the closure is rotated, in a retrograde manner, the frangible means are severed.
