1. A portable, stackable container for liquids, constituting a first container on which a second like container may be stacked, comprising:

  • a shell having four side walls of stainless steel in a generally rectangular configuration;

    a stainless steel bottom wall closing the bottom of the shell and including triangular portions with the apex thereof displaced considerably nearer one side of the bottom wall than the opposed side, each triangular portion having a base adjoining a side wall and sloping downwardly, and a delivery opening at the apex of the bottom wall triangulation to assure complete drainage of liquid;

    a delivery hose underneath the bottom wall, including a valve connected to the delivery opening in association therewith, access to the valve being facilitated by the closer position of the delivery opening aforesaid;

    a stainless steel top wall enclosing the side walls of the shell and sloping upwardly to meet an enlarged opening which is normally closed by a removable lid, removal of the lid allowing cleaning equipment to be inserted through the enlarged opening and cleaning fluids to be drained therefrom upon inversion of the container, said lid having a filling opening, which filling opening is offset from the delivery opening and positioned nearer one side of the top wall than the opposed side to facilitate connection of said hose to the filling opening of a like, second container also having a delivery opening in the bottom wall offset from a filling opening in the top wall;

    two elongated fork lift channels attached to the underside of the bottom well, each channel including a horizontal top plate which is spaced in protecting relation from the bottom wall to provide a lifting surface for the forks of a lift truck beneath the bottom wall while the channels allow for transporting, inversion and cleaning of the container when supported by a fork lift;

    a plurality of bottom legs adjacent the four corners of the shell and extending downwardly therefrom to support the container;

    a plurality of upwardly opening leg positioners, one for each leg, near the top of the container and also positioned at the corners of the shell to receive the legs of a second like container stacked thereon; and

    horizontal support plates mounted to said leg positioners for supporting the legs of the second container without engagement between the legs and the top wall of the container therebeneath.
