The primary object of the invention is to provide a metal beer keg which is formed from a 5 comparatively few number of parts and yet which is extremely strong and durable.

A further object of the invention is to provide the main body portion of a metallic beer keg by forming the same from a pair of oppositely arranged dished members, which may be pressed or stamped from suitable gauge material and wherein the edges of the two dished members are suitably joined for a seam.

A further object of the invention is to provide a beer keg with depressions or cavities at its opposite ends, one of said cavities being designed to receive and house the dispensing mechanism for the contents of the keg and wherein a cover is applied to the end of the keg to conceal the dispensing mechanism.

Still a further object of the invention is to provide a beer keg which is formed with a cavity or depression at one end adapted to be closed by a cover so as to form a compartment for receiving a refrigerating medium.
