ABSTRACT:
A getter capsule comprising at least one particular container (1 or 10) containing getter particles (9) is useful for removing reactive gases in at least one vacuum space(21d or 22d). The particular container (1 or 10) may be made of a material containing sintered particles or may be made of a combination of a filtering means (11) and a perforated inorganic pipe or cup (12). At least one closing means (5 or 15) employed in each container (1 or 10) to close or cover the opening (4 or 14) of the container (1 or 10) may be particularly designed to prevent the getter particles (9) from escaping the container (1 or 10) without using any sealants, even when the container (1 or 10) is subject to vibrations.
