Abstract
A method of filling a capsule having a hollow body portion and a hollow neck portion extending from it with fluid under pressure comprising the steps: a) applying in a fluid tight manner a filling cap to the free end of the neck portion initially to evacuate the hollow body portion and subsequently to fill the hollow body portion with the fluid under pressure; b) with the filling cap in place and pressure applied at least 30 bars, crimping the neck portion at a location spaced from the free end of the neck portion; c) removing the filling cap and thereby revealing the free end of the neck portion d) applying a second crimp at or immediately adjacent the free end of the neck portion; e) welding the free end to seal the capsule which can be made from aluminum or an aluminum alloy.
