A pressure vessel 10 comprises a container 13 for storing contents under pressure, a head section 11 and a base section 12. The head section 11 and base section 12 locate on opposing ends of the container 13 and each have projecting fingers 22, preferably five, which engage around the container 13. A retaining ring 14 locates around the container 13 and holds the fingers 22 in place. The head section 11, base section 12 and ring 14 all serve to resist expansion of the container 13. The pressure vessel may serve to store beverages such as beer. The head section 11 and the base section 12 may have handling rings 24, 25 to aid manual handling. The vessel 10 may be stood on the handing ring 25 of the base section 12.. A groove may be formed in the side of the container to permit resilient inward radial deformation of one set of fingers during assembly of the vessel 10. |
