Abstract
Abstract A multi-compartment case, in particular such a case for air travel, features a rectangular parallelpiped shaped part with a handle on one narrow side and, projecting beyond the narrow side a tall part which is provided with a hinged lid on the front wall facing the other part and in its interior a device for hanging up clothes. The narrow side projects as a wall section out of a front wall of two tall case shells which are made mainly of light weight metal and are hinged together. The narrow side features connecting elements to secure a briefcase which, when joined to the case, makes the whole into a rectangular parallelpiped.
