ABSTRACT OF THE DISCLOSURE A plastic or equivalent thin film bag is rolled up inside 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, 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. Thus a packaging array for fluent materials comprises a thin flexible-walled container or bag having a common area with an uncoiled spiral constant force spring strip and positioned to coil up by rolling up a container bag tail inside the coil spring spiral as contents are dis- charged. The bag is placed in a container confining the fluid bag contents to occupy a position with a height corresponding to that of the constant force coil spring spiral diameter thereby to exert by the spiral a sub- stantially constant force aiding the discharge of the contents over the entire bag capacity. The spring carries a contents gage which shows the amount of materials left in the bag.
