Abstract
This invention is a total release actuator having a structure that provides a time delay between the activation of an aerosol valve in an associated aerosol container and the discharge of product through the actuator. The structure effecting the time delay is an inflatable and movable component which slowly expands and moves upwardly when product is slowly introduced from the container to a closed chamber defined in part by the inflatable and movable component; the closed chamber being initially out of registry with a discharge conduit and orifice but which, after the chamber is slowly filled with product, moves into register with the said discharge conduit and orifice and product is discharged.
Claims7
An actuator for the total release of the product within a valved aerosol container, said actuator having a mechanism to delay the discharge of the product through the actuator from the time of the initial opening of the aerosol valve comprising:
- (a) means for mounting the actuator to a valved aerosol container, including an upstanding outer walls;
- (b) a socket portion having a recess at one end to receive in sealed relation a valve stem of an aerosol valve, the socket portion having an upstanding portion with a conduit therein extending upwardly from the valve stem receiving recess and terminating as an opening through the upstanding portion;
- said upstanding portion further having a groove in its outer surface commencing at the top of the upstanding portion;
- (c) the socket portion having a platform extending radially outward from the upstanding portion, the platform having a downwardly extending wall and forming a hinge connection with the means for mounting the actuator to a valved aerosol container, the downwardly extending wall further having a means for actuating and holding in open position the aerosol valve of an associated container;
- (d) an inflatable and movable component disposed in an interference and sliding relationship with the outside surface of the socket portion and defining, together with said socket portion, a closed chamber;
- (e) the groove and conduit opening in the upstanding wall of the socket being disposed so as to be out of registry with the interior of the closed chamber when the valve of an associated aerosol container is in a closed or non-actuated position.
