A pop-up valve closure for a container has a cap with a well defined therein. A valve with a valve sleeve is movably mounted in this well. The valve is movable between a closed position and a popped-up open position. An actuator can lock and unlock the valve in order to permit opening and closing of the valve. When the actuator unlocks the valve, a spring or other device can automatically move the valve from the closed position to the open position. This unlocking can be carried out with finger pressure applied to a tilting button of the actuator.
