Abstract: The invention relates to a filling and/or emptying apparatus (1) and to methods for filling and/or emptying flexible containers (5), particularly sacks, with in particular hazardous, loose substances, preferably in powder form, comprising a filling and/or emptying neck (2) with an open end portion and at least one deformable disposable fastening ring (9), wherein the disposable fastening ring (9) is designed in relation to the internal diameter of the filling and/or emptying neck (2) such that once a container edge (7) is folded over around the fastening ring, preferably from radially inside to the outside, it is possible to insert, particularly to insert manually, the disposable fastening ring (9) in an end portion of the filling and/or emptying neck (2) so that the disposable fastening ring (9) is arranged substantially concentrically with the filling and/or emptying neck (2), and a radially outer fold-over portion (8) of the container edge (7) is arranged and/or clamped between an inner surface of the fill

Abstract: The invention relates to a discharging apparatus for discharging loose and in particular pulverulent material that is hazardous to health from rigid or flexible containers (12), in particular bags and barrels (13), comprising a discharge chamber (2) which has a discharge opening (5) for discharging the material after removal from a container (12) and which additionally has an insertion opening (3) for at least partial insertion of a container (12) into the discharge chamber (2). According to the invention, the discharge chamber (2) has a ventilation opening (4) which is arranged at a side of the discharge chamber (2) opposite the insertion opening (3) and which is connected to pump means (10) in such a way that an air stream can be generated inside the discharge chamber (2), which causes a laminar air flow starting from the insertion opening (3) and leading in the direction of the ventilation opening (4).

Abstract: A minimal-amount powder metering device (1) for pharmaceutical or chemical applications, for metering powder volumes of less than 1 cm3, comprising a metering chamber (3) which is delimited by a surrounding wall (9) and which can be connected to a vacuum source (28) for suctioning powder in order to fill the metering chamber (3) with powder to be metered, filter means for retaining powder in the metering chamber (3) during a suctioning process being associated with the metering chamber (3), including the filter means are formed by the surrounding wall (9) and including at least one suction opening (12, 13) which serves to retain the powder in the metering chamber (3) and through which a vacuum can be applied to the metering chamber (3) is formed in the surrounding wall (9).

Abstract: A powder metering apparatus (1) having a metering chamber (2) which defines a powder metering volume (3) and can be emptied through an outlet opening (11), wherein, in order to draw in powder (9) from a powder supply line (10) through a diaphragm (5) which bounds the metering chamber (2), a negative pressure (8) can be applied to the metering chamber (2). The diaphragm (5) is arranged such that the latter can be adjusted relative to the outlet opening (11) in order to set the powder metering volume (3) and/or to empty the metering chamber (2).

Abstract: The invention is directed at a process for enabling the packaging of a powder (32), in particular a pharmaceutical product powder, including the steps of: providing a first bag (9) from a flexible packaging material; fixing the opening (19) of the first bag (9) to a lower outlet (11) of a DCS (drum containment system) glove box (1); inside the DSC glove box (1) pulling a continuous liner (14) at a closed end of the liner (14) and inserting the liner (14) into the first bag (9), thus providing a second bag (16) inside the first bag (9); filling the second bag (16) with the powder (32), in particular through an upper opening of the DCS glove box (1); closing the second bag (16) by disconnecting the continuous liner (14); closing the first bag (9) and removing the first and second bags (9, 16) from the DSC glove box (1). Furthermore the invention is directed at an apparatus for performing the process.
