A pivotable disc closure actuator, a closure including the actuator and the closure combined with a bottle or other container. The actuator includes a closing surface which includes a product dispensing opening at a front thereof, at least two pivots on the closing surface, an extension panel extending from a peripheral wall of the closing surface and having a locking and an unlocking position, the pivots being intermediate the product opening and the extension panel, and the extension panel having a latch member extending inwardly toward the closing surface when the extension panel is in the locked position. The closure may include a closure base which may in turn include a cutout or opening in its outer wall. In its locked position the extension panel may rest on a surface of the cut out or outer wall to prevent the actuator from rotating from its closed position to an open position.
