Abstract:
1. An actuator assembly suitable for dispensing a pressurized chemical from an aerosol container to ambient environment, albeit with a time delay after initial activation of the actuator assembly, the aerosol container having a release valve for controlling the release of the chemical from the container to the ambient environment, the actuator assembly comprising: an actuator mountable on the aerosol container to be operably connectable to the release valve for at least initially activating the release valve, the actuator including a flow path through which chemical from the container must pass when released there from; and a time delay system associated with the release valve, the time delay system including a burstable barrier and an extrudable plug, both of which initially close the flow path, the barrier being positioned between the plug and release valve; whereby, upon initial activation of the actuator assembly, pressure of the chemical thus released from the container can both burst the burstable barrier and also then cause the chemical to extrude or penetrate the extrudable plug before escaping to the ambient environment.
