CA 2160643

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 contain mutually cooperable, releasably locking engagement means. Intermittent aerosol dispensing is achieved without interference by the engagement means. Continuous aerosol dispensing is achieved by having the user position a movable engagement means so that it engages the other engagement means while the actuator button is held by the user in its dispensing position. The user then releases the actuator button and the engagement means retain the actuator button in the atomization position for continuous spraying. The second engagement means may be released to stop the continuous spray simply by again pressing the actuator button.

Cette invention concerne une coiffe pour boîte aérosol qui permet la diffusion du contenu de la boîte sous forme de jet pulvérisé soit intermittent soit continu. L'objet de l'invention est particulièrement utile pour la projection d'un jet ou d'un brouillard d'insecticide en fines gouttelettes et se caractérise par une fabrication économique en raison du faible nombre de pièces mobiles qui la composent. La coiffe est constituée d'une coquille comportant un bouton de pulvérisation équipé d'un moyen de verrouillage déblocable à deux éléments conjugués. La projection d'un jet continu se fait par enclenchement du moyen de verrouillage une fois le bouton de pulvérisation enfoncé. L'utilisateur peut alors relâcher le bouton qui sera maintenu en position enfoncée de jet continu par le moyen de verrouillage. Celui-ci peut être débloqué pour une projection intermittente par simple pression sur le bouton de pulvérisation.
