Patent number: 10905844Abstract: An improved aerosol dispensing apparatus includes an aerosol container, a discharge piece movably mounted to the aerosol container, a flow control valve mounted within the discharge piece, a battery, and an electronically controlled metering valve electronically connected to the battery and in fluid communication with the flow control valve. The flow control valve is movable between an open position wherein a volume of an aerosol formulation is directed from the aerosol container through the flow control valve to the metering valve, and a closed position, wherein the metering valve is configured to precisely control a flow of the aerosol formulation outward of the discharge piece. A solenoid is electronically connected to the battery and is movable between an actuated position wherein the solenoid urges the flow control valve into the open position, and an un-actuated position wherein the flow control valve remains in the closed position.Type: GrantFiled: February 4, 2019Date of Patent: February 2, 2021Assignees: DunAn Microstaq, Inc., Pearl Therapeutics, Inc.Inventors: E. Nelson Fuller, Parthiban Arunasalam, Joseph Nguyen, Joe A.
