Abstract
A bag for placing in a cylindrical or barrel-shaped container includes front and rear panels (11, 12) between which side panels (13, 14) folded double are positioned. The base of the bag runs to a point along edges (17, 18). When the bag is unfolded this is able to come into contact with the inside wall of a cylindrical or barrel-shaped container having a round base and neck without significant stresses. As a result high material stresses are avoided and the barrier properties of the bag are retained. The front and rear panels (11, 12) can be joined to one another by breakable fastening lips (22, 23).
