Abstract
A capsule for storing a propellant fluid, for example, helium under pressure comprises a hollow body which includes a frangible area. An anchor member attaches an arm to the frangible area such that when a force is applied to the arm, said force together with the helium under pressure will cause the frangible area to rupture outwardly of the hollow body thereby to release the helium.
