Abstract
A portable tank has a sloped bottom structure with a smooth internal bottom surface sloping along a single bend toward a bottom discharge opening in the bottom plate. The sloped bottom structure has upturned curved side portions merging with upwardly extending wall portions joining the vertical walls of the tank along a horizontal edge. The bottom structure is formed by forming a discharge opening in a flat bottom plate near one edge, forming a gap between the opening and the edge which diverges from the gap toward the edge, bending the sides of the plate upwardly, and bringing the side of the gap together to mate in a closed seam bowing the bottom of the plate outward at the opening to slope the bottom towards the discharge opening.
