Device and method for transferring a packaging unit into a barrier system for pharmaceuticals

A method for transferring a packaging unit (22) into a barrier system (12) for pharmaceuticals, wherein the packaging unit (22) comprises a sterilized container (24) and at least one sterile product (26) arranged therein and wherein the packaging unit (22), in an initial state, is surrounded by an outer packaging (30) sterilized at least on the inside, wherein the barrier system (12) has an access opening (20) through which the packaging unit (22) can be transferred from a surrounding region (16) of the barrier system (12) into an interior (14) of the barrier system (12), wherein a film tube (50) which is closed on the end side is arranged or is to be arranged in the surrounding region (16) of the barrier system (12), the interior (52) of the film tube communicating with the access opening (20), characterized in that a connection region (72) is produced between an outer face (68) of a planar cover portion (70) of the outer packaging (30) and a planar overlap portion (74) of an outer face (64) of the film tube (50) overlapping the cover portion (70), in that subsequently the connection region (72) or a part of the connection region (72) is locally separated and at the same time the material (66) of the film tube (50) and the material of the outer packaging is cut through, wherein the connection between the overlap portion (74) of the film tube (50) and the cover portion (70) of the outer packaging (30) and an isolation associated therewith of the outer face (68) of the cover portion (70) of the container (24) is maintained, but at the same time a through-opening is produced, and in that the packaging unit (22) is moved out of the outer packaging (30) through the through-opening into the interior (52) of the film tube (50) and is transferred therefrom into the interior (14) of the barrier system (12).
