A dispenser for use with an aerosol container, the aerosol container having a valve for dispensing aerosol, the valve having a hollow valve stem which is movable relative to the container between an extended closed position and a depressed open position for discharge of aerosol, the dispenser comprising: a housing with a front face terminating in a mouthpiece, which front face has an inside surface and which housing is adapted to receive an aerosol container and comprises a support block with a socket adapted to receive the valve stem, which support block has an orifice allowing open communication between the valve and the mouthpiece; an actuator manually depressable between a closed position and an actuating position, having a first end pivotally mounted to the housing, a second manually depressable end, and a releasably engageable stop means to prevent unintended depression of the manually depressable end to the actuating position; and a catch means for preventing unintended depression of the actuator, which means is engageable with the stop means of the actuator when the actuator is in the closed position; and a gate means to open and close the mouthpiece, which gate means is mounted on the front face of the housing and comprises a wall section and a lift means to slide the wall section between a closed position in which the stop means of the actuator is engageable with the catch means, and the open communication between the valve and the mouthpiece is interrupted, and an open position in which open communication exists between the valve and the mouthpiece, and the stop means of the actuator is not engageable with the catch means thus permitting manual depression of the actuator to the actuating position.
