Abstract
To reliably and simply connect one end of a double-ended discharge vessel it (1) and a surrounding envelope (11) to a base (8), the base has a base sleeve (8a) which encloses a base holder portion (8b). The envelope (11) is melt-connected to the discharge vessel unit (1), for example just beyond pinch seals formed thereon, and is additionally formed with an extension (11a) which is, in turn, melt-connected to the holder portion (8b) of the base. Preferably, a metallic cuff is placed within the holder portion so that, by high-frequency inductive heating, a reception region (8d) of the holder portion can melt and tightly grip the extension (11a) of the envelope. To improve adhesion, the surface of the extension region (11a) may be ribbed, knurled or otherwise, slightly deformed.
