A fluid container (1) for containing a fluid under pressure, comprising a tubular member (2) closed by a closure member (3), said closure member (3) having a tubular part (34) extending generally axially within the tubular member (2) to form at least one peripheral space (G) between the closure member (3) and tubular member (2), the space being sealed from the inside of the container and having at least one vent passage (5) leading from the space to outside the container (1). This construction enables radial pressure inside the container (1) to assist in providing a strong joint. The container (1) may include a pressure-relief safety device in the form of at least one frangible wall portion (R) of said tubular part (3A), said frangible wall portion (R) being arranged to break in the event that the pressure in the container (1) exceeds a predetermined safety limit. |
