Abstract
A tamper-evident closure for sealing a package cooperates with a separately applied indicator ring, which is torn apart during the opening of the package, so that a portion of the indicator ring drops clear of the closure to indicate that the closure has been turned at least partially off of the package. The indicator ring has a lower mounting portion and an upper ratchet and indicating portion which is connected to the lower mounting portion of the ring by a series of frangible connectors which are ruptured as the cap is removed.
