摘要 |
A capsule 4 for storing a fluid for example helium under pressure comprises a hollow body from which extends a hollow neck 12. A stopper 5 engages with the neck in a fluid tight manner. The stopper 5 includes a main hollow portion 13 and a stem 10 extending outwardly from the main hollow portion. The root 14 of the stem 10 where it joins the main hollow portion 13 forms a frangible section which when broken will allow fluid in the capsule to escape under pressure. |
