Abstract
A fluid tank assembly is designed for stacking with similar assemblies. The fluid tank assembly includes a base having a plurality of upright stacking legs, a tank having a liquid-receiving chamber received on and supported by the base, and couplers for connecting the tank to the stacking legs adjacent the upper ends of the latter. The couplers away be provided as fasteners such as bolts and receivers whereby the tank prevents the legs from spreading outwardly. Alternatively, the couplers may be provided as bosses molded into the tank which interfit with corresponding slots on the stacking legs. The tank is preferably permitted to shift relative to the base to accommodate movement during filling and emptying and shifting during transport. The couplers avoid the necessity of separate protective tops or other structure which joins the tops of the legs together, but rather uses the tank as a structural component without imparting significant vertical loads thereto.
