Abstract: An automatic pressure relieving aerosol product and container having an actuator member held fixedly against outward movement with respect to the can, and a valve carrying member that will move the valve stem against the actuator in response to excess pressure. When such pressure is present in the can, the valve carrying member moves upwardly whereupon the valve is opened thereby relieving the pressure. The actuator is of the type that will normally be moved with hand pressure to open the valve, thereby permitting the aerosol container to be operated in the usual manner under normal conditions.

Abstract: A valve is described wherein vaporous purging substance in the head space above the material to be dispensed in an aerosol container can be introduced into the valve in such quantity as to clean the valve and reduce the flow of the material to be dispensed therethrough. A method of cleaning a valve is also described.
