    DETAILED DESCRIPTION OF THE EMBODIMENTS

    [0079] As already mentioned, FIG. 1A and FIG. 1B show the state of the art and were already explained in detail at the beginning, so that a further discussion can be dispensed with here.

    [0080] FIG. 2A shows a cross-section through a first embodiment of a sealing module according to the invention, which in the following is referred to as a whole with the reference sign 1. The reference signs used in FIG. 2A to FIG. 9B have no inverted comma, as these figures refer to embodiments of the present invention. As already mentioned above, only the reference signs of FIG. 1A and FIG. 1B have an inverted comma, as these refer to the known state of the art.

    [0081] According to FIG. 2A, the sealing module 1 comprises a supporting unit 8 with a supporting surface 8a and a pressing unit 9 with a pressing surface 9b. The supporting surface is designed as a supporting surface profile and the pressing surface is designed as a corresponding pressing surface profile. The supporting unit 8 is fixedly arranged in the sealing module 1 and the pressing unit 9 is movable in the axial direction relative to an axis A3 of the supporting unit 8. The supporting unit 8 is designed as a holding unit for supporting the container flange 6. The container 2 to be sealed is secured at the container flange 6 in the axial direction to the axis A3 by the holding unit 8. In addition, the container 2 is fixed in the radial direction to the axis A3 by the holding unit 8.

    [0082] As FIG. 2B shows, the pressing unit 9 is moved in the axial direction to the support unit 8 during the sealing process. In doing so, the lid flange 7 and the container flange 6 are pressed together in a form-locking way between the supporting surface profile 8a and the pressing surface profile 9a by an axially acting force F.sub.A.

    [0083] A variant of the embodiment described is that the pressing unit 9 is fixedly arranged in the sealing device 1 and the supporting unit 8 can be displaced axial to the axis A3 and relative to the pressing unit 9.

    [0084] The sealing module 1 additionally comprises an ejection element 12 for releasing the container. In the embodiment shown, the ejection element 12 is movably arranged in the sealing module 1. Alternatively, however, it is also possible that the ejection element 12 is fixedly arranged in the sealing module 1. After the sealing process has been completed, the sealed container can be released from the supporting unit 8 via the ejection element 12. For this purpose, the ejection element 12 is moved in the axial direction against the bottom of the container 2, e.g. by a motor not shown. In doing so, the ejection element exerts an axial force on the container, whereby the container is released from the supporting unit 8. A second embodiment of the sealing module according to the invention shows substantially the same structure as the sealing module according to the first embodiment (FIG. 2A and FIG. 2B).

    [0085] In contrast to the first embodiment, the second embodiment of the sealing module 1 additionally comprises a movable radial pressing unit 10 with a radial pressing surface 10a. Like the pressing unit 9, the radial pressing unit 10 is movable in the axial direction relative to the axis A3 of the supporting unit 8.

    [0086] As FIG. 3B shows, both the pressing unit 9 and the radial pressing unit 10 are displaced in the axial direction to the supporting unit 8 during the sealing process. In doing so, as in the first embodiment, the lid flange 7 and the container flange 6 are pressed together in a form-locking way between the supporting surface profile 8a and the pressing surface profile 9a by an axially acting force F.sub.A. In addition, the lid flange 7 and the container flange 6 are pressed together by the radial pressing unit 10 also by a radially acting force F.sub.R.

    [0087] A third embodiment of the sealing module according to the invention (FIG. 4A) substantially shows the same structure as the sealing module according to the second embodiment (FIG. 3A and FIG. 3B).

    [0088] In contrast to the second embodiment, in this embodiment, the radial pressing unit 10 with the radial pressing surface 10a is not movable in the axial direction but in the radial direction relative to the axis A3 of the support unit 8.

    [0089] As FIG. 4B shows, the pressing unit 9 is displaced in the axial direction to the support unit 8 and the radial pressing unit 10 is displaced in the radial direction to the support unit 8 during the sealing process. In doing so, as in the second embodiment, the lid flange 7 and the container flange 6 are pressed together in a form-locking way between the supporting surface profile 8b and the pressing surface profile 9b by an axially acting force FA. In addition, the lid flange 7 and the container flange 6 are pressed together by the radial pressing unit 10, also by a radially acting force F.sub.R.

    [0090] A fourth embodiment of the sealing module according to the invention (FIG. 5A and FIG. 5B) substantially shows the same structure as the sealing module 1 according to the first embodiment (FIG. 2A and FIG. 2B). The sealing module 1 comprises a supporting unit 8 with a supporting surface 8a and a pressing unit 9 with a pressing surface 9b. The supporting unit 1 is fixedly arranged in the sealing module 1 and the pressing unit 9 is movable in the axial direction relative to an axis A3 of the supporting unit 8.

    [0091] In contrast to the first embodiment, in this embodiment the supporting surface 8a is designed as a ring, which serves to support the container flange 6. The container to be sealed is secured at the container flange 6 in the axial direction to the axis A3 by the supporting surface 8a. In addition, the container 2 is fixed in the radial direction to the axis A3 by the supporting surface 8a.

    [0092] Furthermore, in contrast to the first embodiment, the pressing surface 9a and the pressing unit 9 are designed in such a way that the lid flange 7 and the container flange 6 are pressed together in a form-locking way during the sealing process (FIG. 5B) both by an axially acting force F.sub.A and by a radially acting force F.sub.R.

    [0093] FIG. 6A and FIG. 6B schematically show a first and a second embodiment of a sealing device 13 according to the invention. The sealing device 13 comprises a plurality of sealing modules 1 in each case. According to the first embodiment (FIG. 6A), the sealing device 13 has a longitudinal axis A4, which is designed as a rotation axis. The individual sealing modules 1 are arranged spaced apart in a circumferential direction U extending about the longitudinal axis A4. According to the second embodiment (FIG. 6B), the sealing device 13 has a vertical plane VE in which the individual sealing modules 1 are arranged spaced apart from each other.
