ABSTRACT:
The present invention relates to a new and improved collapsible container for use in transporting and dispensing fluids, primarily gasoline. In its broadest context, the present invention includes a flexible liner with at least three sides. Furthermore, metallic reinforcing walls are secured to at least two of these walls. Due to the material characteristics of the reinforcing walls, specifically a memory steel, a spring force is created which tends to urge the reinforcing walls inwardly. However, the presence of a fluid within the container overcomes this spring force and keeps the container in its non-collapsed or opened configuration.
