ABSTRACT:
A safety locking device particularly adapted for use in selectively inhibiting actuation of an aerosol valve assembly for an aerosol container having a movable valve stem connected to a push-button actuator head which stem is slidable within a valve pedestal formed on the valve assembly. The safety locking device embodies, in integral combination, at least a pair of first and second locking means formed adjacent opposite ends thereof and a biased hinge means. Interconnecting the first and second locking means is the biased hinge means which biases the second locking means relative to the first locking means such that whenever the first locking means is secured to the valve pedestal, the second locking means is biased to the locking position where it is interposed between the actuator head and pedestal. In addition, the hinge means automatically returns the second locking means from the unlocked position to the locked position whenever application of forces sufficient to overcome the bias of the biased hinge means for urging the second locking means towards the unlocked position is released.
