ABSTRACT:
An apparatus for the pneumatic discharge of containers which are lined with a foil bag which contains a pulverulent mass comprises a tubular connection to the container having an interior sleeve portion opening into the container and providing a rotatable support for a double walled suction tube. The double walled suction tube has an interior end with a central opening into the container and an annular opening which communicates with the space between the walls and which is supplied with an air for the purpose of breaking up the pulverulent mass at the entrance to the central suction. Additional air is supplied through openings in the sleeve to the space surrounding the suction tube and the sleeve advantageously includes an insert at its inner end forming a nozzle-like divergent sections with a flow of air into the container to support the bag against collapse.
