ABSTRACT OF DISCLOSURE A one-piece molded closure of plastic which threads onto a container with a fairly specific exterior configuration and provides a combination such that when the closure is unthreaded, a tamper-indicating ring becomes separated from the lower end of the closure skirt. The indicating ring or band is joined to the closure by frangible bridges and a flexible stop ring is formed within the band and extends inwardly and upwardly when the closure is applied to a container finish. The container finish has a first radial bead and an inwardly tapering side wall surface therebeneath which leads to an abrupt, inwardly extending ledge. The flexible stop ring rests on the tapered surface, when the closure is applied. After closure removal, the stop ring and band drops below the ledge indicating that the closure has been removed.
