<p>A collapsible, portable, open-top container for liquids, preferably water, having a bottom and side walls made of a flexible, high-tensile-strength material, and a ring-shaped float body disposed along the upper edge portion of the side walls, said float body in its entirety being disposed inwardly of the circumference of said bottom. When the container is filled with water it rises to its full height and the side walls converge strongly toward the top such that the container assumes the shape of a truncated cone and thereby being quite stable with respect to loading on the upper edge of the walls and in regard to the nature of the foundation on which it rests. Said container can be placed on an uneven or even sloping foundation and makes a very practical water reservoir for various purposes.</p> |
