Abstract
A threaded one piece closure having a tamper indicating band attached to the lower end of a cap skirt by frangible bridges which fracture upon the initial opening of the closure leaving the detached band on the container indicating the initial opening or tampering. The bottom of the tamper indicating band is formed with a plurality of equally spaced stop segments attached by flexible webs. The tamper indicating band is also formed with a plurality of rectangular windows in line with the stop segments. The flexible webs permit the swinging of the stop segments into an operative position engaged within the windows so that they will coact with a flange or ratchet teeth on the container to provide a means for fracturing the frangible bridges upon unthreading of the cap.
