Abstract: A dimensionally stable receptacle for accommodating at least one flexible packing drum in an interior space of the receptacle comprises a bottom, a side wall at least one suction line leading into the interior space, at least one passage device, and at least one feed opening. At least one first docking coupling is located in or adjacent to the feed opening and/or forming the feed opening, for docking a first feeding conduit for bulk material such that, when a flexible packing drums located in the receptacle is coupled to the first docking coupling of the feed opening, the interior space may be sealed, in which a state of vacuum is obtainable through suction in the suction line. The invention further relates to a filling module and method for filling a flexible packing drum with bulk material.
