In the outer vessel accommodating the insert is an opening for a sealing bung socket, which has a bore with peripheral sealing lips to take the devices, also a peripheral groove at the top. The insert is a bag (1), fixed at the underside of the socket (2) which has between the top and bottom sealing lips (3, 4) a transvers drilling (5) leading to an annular channel (6). The filling device is a pipe (12) forming a sealed joint where it fits in the socket, and has a beer delivery passage and a separate one closed at the bottom and with a drilling (15) in an outer sidewall in line with the transverse one in the socket in the working position. The tapping device using air or carbon dioxide, has two separate passages, one tapping off beer and the other with a drilling in the outer wall in line with the socket drilling to deliver air or carbon dioxide.
