Abstract: A dispenser apparatus for receipt on a receptacle and operable to dispense a volume of liquid from a reservoir through an orifice includes means for injecting air into the liquid being dispensed to increase the level of atomization. The means includes a secondary chamber which normally is open to atmosphere yet adapted to be pressurized upon actuation of the pumping mechanism of the dispenser. The secondary chamber interior communicates through an opening with the liquid flow path to the orifice. The secondary chamber provides a secondary pump isolated from, but synchronized with the primary pumping mechanism.

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.
