A keg is formed from (A) a shaped jacket or liner forming a container, obtained from at least two nonsymmetrical parts ( 1 a , 1 b) welded together, one of the parts containing an opening provided with a neck, and (B) a filling/tapping device ( 3 ) positioned in the neck of the opening. The part of the container with the filling/tapping opening contains a riser or peripheral skirt ( 13 ) having a height at least equal to that of the outer part of said filling/tapping device and, optionally, sufficient to contain at least one cut-out forming a handle, and while the neck of the opening contains a part ( 9 ) extending inside the lumen of the jacket and having a limited diameter at its end ( 10 ), so as to permit passage and maintenance of the tapping device ( 3 ), and containing at least one other opening ( 11 ), advantageously on the periphery of said opening for passage and maintenance of the tapping device.
