A rotor-style sift-resistant dispensing closure of injection-molded thermoplastic having a base that provides a resilient seal on its dispensing hole and a rotor carried on the base in a position that compresses the seal for sealing effectiveness. The rotor is accurately maintained in a flat configuration by the base which retains the rotor both at its center and at its periphery and which stabilizes the rotor against distortion with upstanding supporting ribs situated between the center and periphery of the rotor.
