Abstract of the Disclosure Beverages are dispensed from time to time from low cost bulk plastic or equivalent thin film bags rolled up inside a dispenser comprising a coiling spiral formed from a strip sheet constant force spring to squeeze out its contents completely and to produce dispensing force at all times. The coil spring strip may be of plastic, metal, elastomer or fibrous materials and may form a wall of the bag so that the container may be made at very low cost for storage of bulk fluids including carbonated beverages for dispensing therefrom one serving at a time. The dispensing method thus provides for maintaining pressure upon stored fluids continuously during dispensing and storage in bulk for dispensing multiple servings from time to time and automatic dispensing without manual pressure upon the container. Accordingly, carbonization is maintained in carbonated beverages by means of spring force pressurization sufficient to prevent effervescence, at normal serving temperatures. Dispensing occurs automatically without entry of air or contamination so that sterile milk or the like may be intermittently dispensed during non-refrigerated storage.
