A tamper-evident dispenser end closure including an imperforate hermetically sealed base and a rotor pivotally connected to the base by a snap-fit between a female pocket formed in the base and an annular male protrusion formed in the rotor. The protrusion contains an opening for visual detection of tampering with the pocket of the base. The base and rotor are retained in a close superposed relationship by the snap-fit pocket and protrusion. Frangible means are provided which tear or break when an attempt is made to separate the base from the rotor thereby evidencing tampering with the rotor. The base and rotor have webs provided with means defining respective dispensing apertures.
