Abstract

A flat bottom tank provides for complete drainage of liquid contents through sloped drainage in the bottom head. The bottom head has a raised center portion which is pyramidal shaped in one embodiment. The sides of the bottom head are broken upwardly to form smooth, rounded wall surfaces. The center portion and the side walls slope downwardly towards one another to form a line of flow extending around the perimeter of the center portion. The line of flow slopes downwardly from a first corner of the bottom head to a second corner of the bottom head which is diagonally opposite the first corner. A drain outlet located adjacent the second corner allows for the drainage of liquid contents from the tank.
