Abstract
A device for stopping leaks in the sidewall of a container such as a 50-55 gallon drum comprising a band of flexible but non-elastic plastic material for manually wrapping around the drum so that a central portion of the band is centered over the leak. An integral inflatable bladder on the inner surface of the central portion is inflatable by a CO.sub.2 cartridge carried on the outer surface of the central portion. A lanyard runs from a CO.sub.2 release valve to one end of the band so that an installer can stand behind the drum while pulling the lanyard to inflate the bladder.
