ABSTRACT:
A portable collapsible tank for storing and insulating hot water or other liquid is contained by an elongate flexible and foldable outer sleeve which defines the outer perimeter of the tank and is formed with sufficient tensile strength to support the tank and stored water. A side wall of insulating material is contained within the sleeve extending around the inside circumference of the sleeve from the top to the bottom of the tank. The outer sleeve and side wall layer overlap and frictionally engage the edge of a floor or base disk of rigid insulating foam material for stability of the tank without tilting and to prevent ballooning of an inner liner from the bottom of the tank. An inner liner of impervious flexible material suitable for contacting hot water, for example, for consumptive use is removeably seated within the side wall and base and extends over the top of the tank. A cover disk of insulating material engages the inner liner and side wall layer at the top of the tank to complete the insulating enclosure.
