Abstract
An improved aerosol dispensing apparatus includes an aerosol container, a discharge piece, an actuator, a flow control canister valve assembly attached to the aerosol container, a battery, and an electronically controlled flow control valve electronically connected to the battery and in fluid communication with the flow control canister valve assembly. The aerosol container and the attached flow control canister valve assembly are further attached to the actuator and the actuator is mounted for slidable movement within the discharge piece. The flow control canister valve assembly is movable between an open position wherein a volume of an aerosol formulation is directed from the aerosol container through the flow control canister valve assembly to the electronically controlled flow control valve, and a closed position wherein the aerosol formulation is not permitted to flow through the flow control canister valve assembly to the electronically controlled flow control valve.
