Abstract: A tank container includes a frame having a front end opposite a rear end that defines a rear plane, a vessel extending between the front end and the rear end of the frame, and a discharge valve assembly. The discharge valve assembly comprises an internal bottom valve, an adaptor, and a discharge valve. The internal bottom valve is positioned within an interior volume of the vessel and the discharge valve is positioned entirely within the frame and offset at least one inch from the rear plane. The adaptor curves downwardly between the internal bottom valve and the discharge valve.
