Abstract
An overcap for a self-pressurized aerosol container is disclosed that dispenses the contents of the container as an aerosol spray in either an intermittent or continuous manner. The overcap is particularly useful in conjunction with the delivery of a fine particle size insecticide spray or fog and is economical to manufacture because it has few moving parts. The overcap comprises a shell containing an aerosol actuator button that further contains a mutually cooperable, releasably locking engagement. Intermittent aerosol dispensing is achieved without interference by the engagement. Continuous aerosol dispensing is achieved by having the user position a movable engagement so that it engages the other engagement while the actuator button is held by the user in its dispensing position. The user then releases the actuator button and the engagement retains the actuator button in the atomization position for continuous spraying. The second engagement may be released to stop the continuous spray simply by again pressing the actuator button.
