8. The method as claimed in claim 6 , comprising the further step of sterilizing an inside space of the transport and packaging container and/or the containers accommodated therein and/or the closure elements by a flow of a gas or vapor through the gas-permeable protective sheet.

9. The method as claimed in claim 5 , wherein a heating device is disposed at the transfer port door in correspondence with an adhesive rim along which the gas-permeable plastic film is bonded to an edge of the side wall of the transport and packaging container, wherein:

the adhesive rim is heated and softened by activating the heating device, and

the gas-permeable plastic film is coupled with the transfer port door in such a manner that the gas-permeable plastic film is pulled off from the side wall of the transport and packaging container by opening the transfer port door after the softening of the adhesive rim.

10. The method as claimed in claim 6 , wherein a heating device is disposed at the transfer port door in correspondence with an adhesive rim along which the gas-permeable plastic film is bonded to the frame, wherein

the adhesive rim is heated and softened by activating the heating device, and

the gas-permeable plastic film is coupled with the transfer port door in such a manner that the gas-permeable plastic film is pulled off from the frame by opening the transfer port door after the softening of the adhesive rim.

11. The method as claimed in claim 5 , wherein:

the gas-permeable protective sheet is disposed on the side wall of the transport and packaging container,

a plurality of recesses or depressions is formed in the side wall of the transport and packaging container,

adjustable gripping devices corresponding to the recesses or depressions are disposed on an outside of the transfer port door,

the gripping devices are adjusted such that, in a first position of the gripping devices, the transport and packaging container is brought freely to a vicinity of the transfer port door of the clean room,

the gripping devices are then adjusted to a second position, in which the gripping devices engage with the corresponding recesses or depressions in the side wall of the transport and packaging container behind the gas-permeable protective sheet for temporarily fixing the gas-permeable protective sheet to the transfer port door,

the transfer port door is opened in the second position of the gripping devices, and

the gripping devices are adjusted back to the first position after closing the transfer port door.

12. The method as claimed in claim 6 , wherein:

the gas-permeable protective sheet is disposed on a frame-like projection formed on the side wall of the transport and packaging container,

a plurality of recesses or depressions is formed in the frame-like projection,

adjustable gripping devices corresponding to the recesses or depressions are disposed on an outside of the transfer port door,

the gripping devices are adjusted such that, in a first position of the gripping devices, the transport and packaging container is brought freely to a vicinity of the transfer port door of the clean room,

the gripping devices are then adjusted to a second position, in which the gripping devices engage with the corresponding recesses or depressions in the frame-like projection behind the gas-permeable protective sheet for temporarily fixing the gas-permeable protective sheet to the transfer port door,

the transfer port door is opened in the second position of the gripping devices, and

the gripping devices are adjusted back to the first position after closing the transfer port door.

13. The method as claimed in claim 1 , wherein all the containers and/or the closure elements are supported in a supporting structure which is accommodated in said transport and packaging container and wherein the supporting structure together with the containers and/or the closure elements supported by it are transferred from the transport and packaging container into the inside space of the clean room by shifting.

14. The method as claimed in claim 13 , wherein the supporting structure comprises a box-shaped bottom part having a bottom, on which the containers are directly supported, and wherein the box-shaped bottom part is shifted directly on a bottom of the transport and packaging container and transferred to the clean room.

15. The method as claimed in claim 13 , wherein the supporting structure comprises a box-shaped upper part, which rests directly, or indirectly with interposition of an intermediate part, on upper ends of the containers.

16. The method as claimed in claim 1 , wherein the transport and packaging container is provided sterile packaged inside a sterile packaging bag and wherein a first space is disposed upstream of the clean room, said first space having a higher concentration of particles, said method further comprising the steps of:

sterilizing an outside of the packaging bag in the first space; and

removing the transport and packaging container from the sterile packaging bag after the step of sterilizing.

17. The method as claimed in claim 16 , wherein the plurality of containers is transferred back into the transport and packaging container after a further processing in the clean room by the following steps:

placing the transport and packaging container in the first space having the higher concentration of particles, so that the side wall of the transport and packaging container with the access opening is arranged directly at the side wall of the clean room and in close proximity to the transfer port door of the clean room;

opening the side wall of the transport and packaging container and the transfer port door so that the access opening of the transport and packaging container communicates with the inside space of the clean room;

transferring the plurality of containers from the inside space of the clean room into the transport and packaging container;

19. The method as claimed in claim 17 , wherein closing the transport and packaging container by the cover is caused by a simultaneous closing of the transfer port door.

20. The method as claimed in claim 17 , further comprising:

sterilizing an outside of the transport and packaging container in the first space having the higher concentration of particles after transferring the plurality of containers into the transport and packaging container;

inserting the transport and packaging container into the sterile packaging bag after the step of sterilizing the outside; and

sealing the sterile packaging bag.

21. The method as claimed in claim 20 , wherein the first space is a first clean room having a higher concentration of particles than the clean room.
