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.

1. 1. A fluid bag and holding apparatus combination comprising: a fluid bag composed of gas-tight flexible material and fillable with a fluid, said bag being flat before being filled with a fluid; a plurality of apparatus surfaces forming a hollow space in which said bag, in an unfilled state, is received, said bag in said unfilled state having edge sides disposed opposite each other; and said apparatus surfaces including a concavely cylindrically curved rigid side wall surface against which said bag in said unfilled state lies flat, and two rigid front wall surfaces spaced from and facing each other and being convexly curved, and against which said edge sides of said bag are adjacent when said bag lies flat against said side wall surface, said front wall surfaces respectively curving said edge sides of said bag to conform to said front wall surfaces.
