ABSTRACT:
The present invention relates to an above-ground double wall portable container for storing liquid products. The container has a primary tank for holding liquid, a secondary tank substantially surrounding the primary tank for containing the stored liquid in the event of a failure in the primary tank, a removable cover for closing the secondary tank and a sealable inlet box through which liquid is introduced into and withdrawn from the primary tank. The container also has a novel system for securing the cover to the tank(s). The system includes a flange member associated with at least one of the tanks, at least one aperture in the flange member which forms a mating set of apertures with at least one aperture in the cover, a fastener for each mating set of apertures, and a clip member for engaging each fastner.
