ABSTRACT:
The invention concerns a package for transporting and storing bulk goods, said package comprising an outer package (11) and an inner package (12). The inner package (12) comprises an outer frame (13) and an inner frame (14) which are at least partly attached to each other. The length of the outer frame (13) of the inner package (12) is greater than or equal to the length of the inner frame of the outer package (11), and the length of the inner frame (14) of the inner package (12) is smaller than or equal to the length of the outer frame of the outer package (11). The internal pressure (P.sub.1) prevailing in the package (10) is received as tension force (F.sub.2) acting on the circumference of the outer package (11), said tension force producing a resultant force (F.sub.3) acting from the corners of the outer package (11) on the package (11), said resultant force (F.sub.3) reducing the tensions prevailing in the inner package ( 12) in that the juncture points (19) of the inner frame (14) and the outer frame (13) of the inner package (12) are substantially free of stresses.
