Abstract (en)
[origin: EP0947760A2] A method of filling a capsule with helium comprises making a first crimp in a neck portion of the capsule spaced from the free end of the neck and subsequently making a second crimp at or immediately adjacent the free end of the neck to effectively form a chamber between the two crimps which inhibits the helium reaching the free end which is subsequently welded. <IMAGE>
