Abstract
Abstract Bung keg having a carry and transport ring molded to the envelope by a connecting web. The bottom edge and the vertical inner wall of the ring provide bearing surfaces for the keg grab. The connecting web merges into the envelope at an acute angle, while the grooved portion of the web, between the vertical inner wall and the keg head, has a bottom point that is in the same horizontal plane as the bottom edge. Besides being formed by a blown method, the bung key can be constructed by welding prefabricated components together.
