A single-piece closure for a container having an inner cap substantially concentrically located with a larger diameter outer cap, and a relatively thin flexible membrane sandwiched between the caps so that the outer cap can move relative to the inner cap. The container has an opening with threads located closest to the opening and a ring with a sawblade-like periphery located proximate the threads. The inner cap has a skirt with mating threads on the interior surface of the skirt. The treads on the inner cap's skirt mate with the treads on the container so that the cap can seal the opening on the container. The outer cap also has a skirt with a plurality of engagement means on the inner surface of the outer cap's skirt that are designed to cooperate with the sawblade ring on the container. The closure is applied to the container by twisting it onto the container so that the threads of the inner cap mate with the threads of the container. When the closure is screwed onto the container, the engagement means slide over and eventually lock into position about the sawblade-shaped ring. The closure can be released by depressing the outer cap (which moves axially and independently with respect to the inner cap thereby moving the engagement means below the saw-shaped ring and unlocking the closure) while simulataneously twisting the cap.
