Pressurized container with non-rigid follower

Abstract

Abstract IN A CONTAINER FOR A FLOWABLE PRODUCT WHICH IS DISPENSED THROUGH AN OUTLET IN THE CONTAINER CONTROLLED BY A VALVE OR CLOSURE, A PLURALITY OF EXPANSIBLE CHAMBERS OR COMPARTMENTS SERIALLY ARRANGED AND SEPARATED FROM EACH OTHER BY DISRUPTABLE PARTITIONS. ONE COMPARTMENT HAS A PRESSURE GENERATING AGENT WHICH, THROUGH THE ADDITION OF A DELAYING AGENT, BEGINS TO GENERATE PRESSURE IN THE COMPARTMENT AFTER THE CONTAINER IS ASSEMBLED AND CHARGED WITH THE PRODUCT TO BE DISPENSED. THE GENERATED PRESSURE CASUES THE COMPARTMENT TO EXPAND AND FORCE THE PRODUCT OUT OF THE CONTAINER THROUGH THE OUTLET OF THE CONTAINER, WHEN THE VALVE OF THE CONTAINER IS OPENED. EXPANSION OF THE COMPARTMENT ALSO DISRUPTS THE ASSOCIATED PARTITION TO PLACE THE ADJACENT COMPARTMENT IN COMMUNICATION WITH THE FIRST COMPARTMENT. CHEMICAL REAGENT IN THE SECOND COMPARTMENT REACTS WITH OR IS ACTIVATED BY THE PRESSURE GENERATING SUBSTANCE IN THE FIRST COMPARTMENT TO FURTHER GENERATE GAS CAUSING CONTINUED EXPANSION OF THE COMPARTMENTS FOR DISPENSING THE PRODUCT UNDER PRESSURE. THIS EXPANSION OF THE COMPARTMENT IN TURN DISRUPTS A SECOND PARTITION TO COMMUNICATE A THIRD COMPARTMENT TO ACTIVATE A CHEMICAL REAGENT IN THE THIRD COMPARTMENT TO FURTHER GENERATE GAS AND PRESSURE FOR DISPENSING THE PRODUCT IN THE SAME MANNER. OTHER FEATURES AND EMBODIMENTS OF THE INVENTION WILL APPEAR SUBSEQUENTLY IN THE SPECIFICATION AND DRAWINGS.
