Abstract: A product dispensing system is disclosed comprised of a gas generating piston action pouch formed in one embodiment from an elongated flexible plastic tubular member having one end portion folded inwardly on the other portion to integrally form an inner tube within an outer tube and outwardly slideable relative thereto. Both ends of the tubular member are sealed thus providing a sealed interstitial cavity between the two portions and a product receptacle within the folded portion. Successive gas generating components are located in the cavity and operatively connected between the portions to generate successive additional quantities of gas as the inner tube moves outwardly from the outer tube to dispense product from the receptacle under relatively constant pressure or any variation or increase or decrease of pressure if shelf life performance dictates specific pressure variances.The pouch itself can be a self-contained product dispenser or can be utilized as an insert component in another container.
