Abstract

An apparatus for holding a flat bag made of a gas-tight flexible material, to be filled with a fluid has an apparatus hollow space that is limited by a concavely cylindrically curved fixed side wall surface for a flat application of the flat bag, and two fixed front wall surfaces that face one another and are each convexly curved, for an inward bending of edge sides, positioned opposite one another, of the bag lying flat against the side wall surface.
