ABSTRACT:
A base for a container for fine material adapted to be discharged pneumatically from the container. The container base has a generally central material outlet in communication with a number of pneumatic feed channels extending radially inwardly from the periphery, the channels dividing the container base into sector-like sections. Each such section has two upwardly converging, oblique surfaces which meet along a ridge-like edge extending towards the container center and at least one of such surfaces is aeratable from below. Overlying each feed channel is an aeratable, downwardly inclined cover having one or more openings at the periphery of the base through which material may pass into the channel.
