An aerosol dispenser and a refill cartridge therefor. The aerosol dispenser has an outer housing adapted to preferentially fit a user's hand with the front of the dispenser presented away from the user. An actuator arm is hinged to the outer housing. A refill cartridge may be removably inserted into the outer housing from beneath. The cartridge includes an aerosol can having a manually activatable valve and an upwardly directed nozzle, which extends through a nozzle port in the actuator arm when the cartridge is inserted within the outer housing. A user can activate the valve by hand by pushing the actuator arm downwardly with a finger. The outer housing is designed to be held on a level surface during such activation. The nozzle includes a longitudinally extended delivery tube in fluid communication with the pressurized material in the can. The delivery tube communicates with a longitudinally extended exit chamber having a spray orifice. The longitudinal axis of the exit chamber is angularly displaced frontwardly from the longitudinal axis of the delivery tube by an angle less than ninety degrees and sufficiently great to deflect frontwardly any otherwise upwardly spraying flow of pressurized material exiting from the spray orifice, thus directing it away from a user holding the aerosol dispenser. A method of dispensing a pressurized material is disclosed, using the aerosol dispenser and cartridge.
