Abstract
A flexible container for storing and dispensing liquids including an inner bag and at least one outer bag, and liquid dispensing means, wherein the inner bag is a collapsible impervious bag for dispensing liquid located within the outer bag, wherein the outer bag's longitudinal dimensions are smaller than the inner bag's dimensions such that at any given imaginary cross section, the inner bag's circumference at the imaginary cross section is greater than the outer bag's circumference at the same imaginary cross section, and wherein the outer bag is made of a substantially non-stretching flexible material, thus imparting the outer bag's high pressure and external impact durability properties to the inner bag.
