In the case of a device for the discharge of flowable material from flexible and more particularly sack or bag like containers through the use of a discharge aspiration device adapted to be introduced from above into the container, lifting tackle is provided able to be brought into holding engagement with a top edge part of the container. The lifting tackle comprises an annular or polygonal holding frame which is able to be moved in a vertical direction by attachment to a reciprocating device and on which the holding elements are secured. The holding frame has a smaller diameter than the container so that the top edge part of the container is drawn radially inward as the container is drawn upward.
