Abstract
A tamperproof dispenser end closure includes a base and a rotor pivotally connected to the base by a hub. The base and rotor have webs provided with means defining respective dispensing apertures. The base and rotor are retained in a close superposed relationship to each other by the hub. Frangible means are provided which tear or break when an attempt is made to separate the base from the rotor so that the base and rotor cannot be pivotally connected again by the hub.
