1. A transport and storage container for liquids comprising:
a pallet understructure;
a cage coupled to the pallet understructure, the cage comprising horizontal and vertical bars made of metal, the vertical bars having upper and lower ends formed by a hollow profile and welded to a lower and an upper circumferential edge profile of the cage, the upper ends of the vertical bars having a connecting portion to be connected to the upper edge profile, said connecting portion being formed by deforming the hollow profile to a flat section, the connecting portions having a passage opening; and a traverse bar formed by a hollow profile and having connecting portions formed on ends of the traverse bar by deforming the hollow profile of the traverse bar to a flat section, the connecting portions of the traverse bar having a fastening opening with a wall for forming a threaded engagement with a connecting screw, the traverse bar further comprising transition portions formed adjacent to the connecting portions and having a cross section recess; and
an inner container made of plastic received in the cage; the inner container having four side walls, a lower and an upper bottom, a sealable filling socket which is formed on the upper bottom and an outlet socket which is formed on a lower portion of a side wall, said outlet socket having a tapping fitting,
wherein the connecting portions of at least two vertical bars, which are disposed on opposite side walls, are connected at the connecting portions by the traverse bar which extends over the upper bottom of the inner container, such that the connecting portions of the vertical bars are connected to the connecting portions of the traverse bar, the connecting portions of the traverse bar are bent upward with respect to a longitudinal portion of the traverse bar, the longitudinal portion extends over the upper bottom of the inner container, and the connection portions of the traverse bar extend in parallel to the connecting portions of the vertical bars, wherein the connecting portions of the vertical bars and the connecting portions of the traverse bar are connected via a screwed joint in each case, such that the connecting screw is guided through the passage opening of the connecting portions of the vertical bars and engaged with the fastening opening of the connection portions of the traverse bar,
wherein the cross section recess of the transition portion of the traverse bar is formed opposite a screw end of the connecting screw protruding from the fastening opening.
