The crossbar is movable with respect to the valve stem between at least a first position blocking depression of the actuator button with respect to the valve stem and a second position permitting depression of the actuator button with respect to the valve stem. The crossbar preferably can be moved from either side of the actuator, and one or more springs preferably are carried by the crossbar for engaging the container and biasing the crossbar to the first or blocking position.
