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.
Claims5
A capsule containing helium comprising a hollow body, a frangible area formed on a surface of the hollow body, a cantilever arm and means for fixedly attaching the cantilever arm to the frangible area such that the arm is spaced from and extends outwardly of the hollow body such that a force, when applied at or adjacent the free end of the cantilever arm in the direction towards the hollow body, will, together with the pressure of the helium in the hollow body, cause the frangible area to rupture outwardly with the subsequent release of the helium.
