Abstract (en)
[origin: EP1492146A2] The method involves producing a pumping hole (14) at a tubular sleeve (7) that ends in a bush (8) of a cap portion. An outer bulb (12) is secured to an inner discharge vessel and a portion of the sleeve. An end of outer bulb is heated and guided onto the sleeve. The volume of outer bulb and the sleeve is evacuated and filled with inert gas. The region of the hole is heated using a laser, and the outer bulb is closed.
