Pallet container for storing and for transporting aseptic liquid filling materials, with a base pallet, a lattice frame which is fastened thereon and consists of metal bars, and a fabric bag or a fabric cover which is to be suspended in said lattice frame and in which a liquid-tight inliner composed of a plastics film and/or metal foil for receiving the liquid filling material is arranged, characterized in that the outer fabric cover and the inner-side liquid-tight inliner composed of plastics film and/or metal foil are provided with a filling and removal fitting preassembled on a filling and removal connection piece of the inliner as a separately premanufactured, flat-folded packet in the delivery state in the form of a modular unit which, as a flat-folded packet, has a folding area with dimensions which are somewhat smaller than the internal size within the lattice frame, and the outer fabric cover to be suspended in the lattice frame and the inner-side inliner are designed within the intended use thereof not to be separable from each other, but rather to be exchangeable only as a complete modular unit, wherein the inliner has a special folding configuration which comprises the following features: - the inliner has, laid out flat, a rectangular blank with an upper side and a lower side with two longer side edges and two short side edges to the front side and to the rear side, - the inliner is provided centrally on the upper side thereof with a small, short degassing connection piece and on the lower side thereof with a larger filling and removal connection piece which is arranged close to the front-side, short side border of the inliner, - in a first step, the corners of the inliner are in each case folded to the center toward the small, short degassing connection piece arranged there, in such a way that a narrow web running transversely with respect to the long side edges remains, - in a second step, the two outer edges of the narrow web are folded over a short distance toward the center in the direction of the central degassing connection piece, thus resulting in an approximately diamond-shaped shape with a front-side and a rear-side point, wherein the filling and removal connection piece sits on the lower side of the front-side diamond point, - in a further step, the two side borders, just folded in, of the narrow web are folded in once again over a further short distance toward the center, - in the final step of the inliner folding, the front-side and the rear-side diamond points are likewise folded in toward the center until close to the central degassing connection piece, and therefore the basic area of the ready-folded-up inliner now has a final folding area with dimensions which are somewhat smaller than the internal size within the lattice frame, wherein the filling and removal connection piece is folded onto the upper side of the inliner and sits tightly against the front-side border of the folded-up inliner, - in the following step, the folded-up inliner is placed onto a thin, stiff base plate and fixed thereon, wherein the liquid-tight inliner is folded flat per se, and the fabric cover together with the inliner located on the inside is folded in differently per se, wherein the folded inliner together with the fitted filling and removal fitting is in the fabric cover is free from any fixing or fastening to the fabric cover and wherein the thin, stiff base plate is arranged within the fabric cover below the inliner. - the inliner has, laid out flat, a rectangular blank with an upper side and a lower side with two longer side edges and two short side edges to the front side and to the rear side, - the inliner is provided centrally on the upper side thereof with a small, short degassing connection piece and on the lower side thereof with a larger filling and removal connection piece which is arranged close to the front-side, short side border of the inliner, - in a first step, the corners of the inliner are in each case folded to the center toward the small, short degassing connection piece arranged there, in such a way that a narrow web running transversely with respect to the long side edges remains, - in a second step, the two outer edges of the narrow web are folded over a short distance toward the center in the direction of the central degassing connection piece, thus resulting in an approximately diamond-shaped shape with a front-side and a rear-side point, wherein the filling and removal connection piece sits on the lower side of the front-side diamond point, - in a further step, the two side borders, just folded in, of the narrow web are folded in once again over a further short distance toward the center, - in the final step of the inliner folding, the front-side and the rear-side diamond points are likewise folded in toward the center until close to the central degassing connection piece, and therefore the basic area of the ready-folded-up inliner now has a final folding area with dimensions which are somewhat smaller than the internal size within the lattice frame, wherein the filling and removal connection piece is folded onto the upper side of the inliner and sits tightly against the front-side border of the folded-up inliner, - in the following step, the folded-up inliner is placed onto a thin, stiff base plate and fixed thereon,
