An actuator cap for use in radially locating a pressurized can in a sprayer device having a cradle for receiving the can. The actuator cap has a recess that engages an engagement land of the cradle and an actuator arm that is so located as to be movable by an actuation pin located in the engagement land. By such movement, the can's valve can be activated and its contents released. A method is also disclosed for activating a pressurized, axially extending can having a forwardly presenting valve while the can is held in pre-determined radial orientation within a sprayer device.
