<p>An apparatus for sealingly fixing a lid (20) to the opening flange (11) of a container body (10) includes a reception device (30) with a support surface (34) for receiving and supporting the container body by abutment of the flange against the support surface. A sealing device (60) applies a pressure to the lid placed between the sealing device and the flange under the formation of a joint which unites the lid with the flange. The reception device has a part of a sphere forming a bounding surface (33). A resting means (40) has a spherical bounding surface (41) for cooperation with the spherical bounding surface of the reception device. A closed space (49) is formed between the reception device and the resting means, this space being supplied with pressure medium for the formation of a gap (43) between the spherical surfaces, whereby the sealing device (60), under abutment against the lid, adjusts, by the intermediary of the lid and the opening flange, the reception device (30) into a position in which the pressure of the sealing device against the lid is substantially uniformly distributed.</p> |
