Abstract
According to the present invention, a dispenser for dispensing a substance from a pressurized canister having a nozzle selectively operable to control release of the substance is provided. The dispenser includes an elongate housing for a pressurized canister, where the housing includes a proximal end, a distal end, and a sidewall. The distal end of the housing has an aperture formed therein, and the sidewall has an opening formed therein. An actuator, which is movable at least axially forward toward the distal end and axially backward toward the proximate end, extends within the elongate housing through the opening and cooperates with a nozzle of the pressurized canister. To operate the dispenser, the actuator is moved to an axially forward firing position in which the actuator causes the nozzle to operate, thereby releasing the substance from the pressurized canister through the aperture in a substantially axial direction.
