ABSTRACT:
So as to provide a container that is inexpensive to manufacture and that promotes a uniform flow of particulate bulk materials therethrough, a vessel is suggested comprising at least two wall segments having a generally downwardly converging wall defining a vertical axis for the vessel, a first upper segment being vertically arranged above a second lower segment, each one of the wall segments having an upper edge and a lower edge, the perimeter of the upper edge of the second lower wall segment being larger than the perimeter of the lower edge of the first upper wall segment the lower edge of the first upper wall segment and the upper edge of the second lower wall segment being positioned proximate to each other and cooperating to provide an enlargement of the cross-sectional area of the volume occupied by the particulate solid material.
