<p>An actuator for an aerosol container having upper and lower rotatable parts which may be rotated between an operative and an inoperative position. When rotated into the operative position, an actuating member is raised by cam action to a position where it engages an arm member, whereby the valve of the aerosol container may be actuated. When rotated to the inoperative position, the actuating member is lowered by cam action to a position where it is flush with the upper rotatable part and does not engage the arm member and whereby the valve of the aerosol container cannot be actuated.</p> |
