PROBLEM TO BE SOLVED: To provide a server which is simple to assemble. SOLUTION: An axial length of an upper portion (9) of a container (1) is approximately the same as that of a partition wall (10) and shorter than an axial length of a lower portion (11) of the container (1). Three mutually butted edges of the upper portion (9) and the lower portion (11) of approximately the same diameter and of the partition wall (10) are joined with one another via one common welded seam (12). Both container portions (9 and 11) include portions to break for safety (24a and 24b). An outer diameter part (13) of at least a head ring (8) does not protrude beyond an outer diameter part (14) of the container at any region. The head ring (8) has a first fitting region (15) for mainly positioning a tap head (6) incorporating a pressure regulator (16) correctly with respect to a gas valve (5) and a second fitting region (17) for mainly positioning the head ring (8) correctly with respect to the gas valve (5). |
