The invention relates to a compressed gas container ( 10 ') comprising a block flange ( 14 ) that is provided on an upper opening in its wall ( 12 ), a flange cover ( 15 ) that is equipped with two extraction valves ( 22 ) being screwed onto said flange. The block flange ( 14 ) is extended radially beyond the region covered by the flange cover ( 15 ) by a solid annular flange ( 40 ), whose outer periphery is welded to the wall ( 12 ) of the container ( 10 ') and whose inner section lying adjacent to the region covered by the flange cover comprises a peripheral groove ( 44 ) in an upper front face ( 42 ), for holding the sealing rib ( 46 ) of an emergency cap. If required, said cap can be screwed onto the annular flange ( 40 ) if a leak occurs in the flange region of the container ( 10 '). Compared to a conventional compressed gas container, the inventive container ( 10 ') is simple to produce, as the latter merely requires a larger flange region in order to provide it with the peripheral groove ( 44 ) and thus the screw construction for the emergency cap ( 50 ).
