Device for sealing a cover element into a casing part of a packaging body made of composite material

Abstract

A device for sealing a cap element into a casing part of a packaging body made of composite material is shown and described. The present invention is based on the object of providing a device of this type, the sealing procedure to be performed in as few steps as possible and the device able to be adapted easily to different cross-sectional shapes of the casing part. This object is achieved in that an inductor ring is provided, the inductor ring encloses the casing part and is tailored to the shape of the circumference of the casing part, the inductor ring includes at least two segments, which form a ring, the segments are displaceable in the plane of the cap element in such a way that the cross-sectional area enclosed by the segments is changeable, a first joint between two segments is implemented as electrically insulating, so that no electrical contact exists between the neighboring segments at the first joint, and the further joints are implemented in such a way that, independent of the relative position of the segments to one another, electrical contact exists between neighboring segments.
