Abstract
A capsule for storing a fluid, for example helium, under pressure comprises a hollow body from which extends a hollow neck. A stopper engages with the neck in a fluid tight manner. The stopper includes a main hollow portion and a stem extending outwardly from the main hollow portion. The root of the stem where it joins the main hollow portion forms a frangible section which, when broken, will allow fluid in the capsule to escape under pressure.
