A package (1) is described for the storage of at least two substances in separate chambers, comprising: a first chamber (3), which contains a flowable first substance (5), and a second chamber (7), wherein the first chamber (3) and the second chamber (7) are in each case formed from portions, sealed to one another in liquid tight manner, of a base film (11) and a cover film (13), the cover film (13) is a composite film comprising a first barrier foil (21) of a metallic material, the base film (11) is a composite film comprising a second barrier foil (29) of a metallic material, wherein the metallic material of the second barrier foil (29) is softer than that of the first barrier foil (21), in a zone (15) connecting the first chamber (3) and the second chamber (7), the base film (11) and the cover film (13) are sealed to one another in such a manner that, by exerting external pressure on the first chamber (3), (a) the sealed joint between the films (11, 13) may break selectively in the stated zone (15), (b) a passage channel (25) may form between the first and the second chambers and (c) the first substance (5) may be transferred from the first into the second chamber, and optionally the cover film (13) has a material weakening in a zone (17) associated with the second chamber (7), such that it is more readily pierceable in this zone than in adjacent zones without material weakening.

The invention claimed is: 1. A package (1) for the storage of at least two substances in separate chambers, comprising: a first chamber (3), which contains a flowable first substance (5), and a second chamber (7), wherein the first chamber (3) and the second chamber (7) are in each case formed from portions, sealed to one another in liquid tight manner, of a base film (11) and a cover film (13), the cover film (13) is a composite film comprising a first barrier foil (21) of a metallic material and a first sealing layer (19) formed of at least one polyolefin, the base film (11) is a composite film comprising a second barrier foil (29) of a metallic material, wherein the metallic material of the second barrier foil (29) is softer than that of the first barrier foil (21), in a zone (15) connecting the first chamber (3) and the second chamber (7), the base film (11) and the cover film (13) are sealed to one another in such a manner that, by exerting external pressure on the first chamber (3), (a) the sealed joint between the films (11, 13) breaks selectively in the stated zone (15), (b) a passage channel (25) may form between the first and the second chambers and (c) the first substance (5) may be transferred from the first into the second chamber, and the cover film (13) has a material weakening in a zone (17) associated with the second chamber (7), such that it is more readily pierceable in this zone than in adjacent zones without material weakening, wherein, in addition to the first barrier film (21) and the first sealing layer (19), the cover film (13) further comprises a stabilising film (23) which has a recess as the material weakening in the zone (17) associated with the second chamber. 2. A package according to claim 1, wherein the base film (11) comprises a second sealing layer (27) formed of at least one polyolefin and having a thickness of preferably 40 μm to 140 μm, the second sealing layer (27) being sealed to the first sealing layer (19). 3. A package according to claim 1, characterised in that a reinforced weld seam is placed in the zone of a common rim around the chambers (3, 7). 4. A package according to claim 1, characterised in that a single weld seam is placed in the zone connecting the first chamber (3) and the second chamber (7). 5. A package according to claim 1, characterised in that the material weakening of the cover film (13) is further based on at least one of the following measures: a reduced thickness of the cover film (13) in the zone associated with the second chamber (7) in comparison with adjacent zones of the cover film, an embossed area or a score in the cover film in the zone associated with the second chamber. 6. A package according to claim 1, characterised in that the seal between the base film (11) and the cover film (13) is weakened in the zone (15) connecting the first chamber (3) and the second chamber (7). 7. A package according to claim 6, characterised in that the seal between the base film (11) and the cover film (13) is weakened in the zone connecting the first chamber and the second chamber on the basis of at least one of the following measures: arrangement of foreign particles, preferably stamped out particles of peel film, in the weakened seal zone, application prior to production of the seal of a substance which impairs sealing of the base film and cover film onto the base and/or cover film in the zone to be weakened, production of the seal by welding the base film and cover film, wherein in the zone connecting the first chamber and the second chamber the welding temperature and/or welding pressure and/or welding time differ from that/those in adjacent zones, or provision of different seal geometries in (a) the zone connecting the first chamber and the second chamber and (b) adjacent zones. 8. A package according to claim 1, characterised in that the base film (11) comprises an outer film (31). 9. A package according to claim 1, characterised in that the base film (11) has a standing area which is opposite the zone of the cover film (13) which has a material weakening and is designed such that the package may be set down on a horizontal surface after or during piercing of the weakened zone (17) without a flowable substance being able to escape from the second chamber (7) into the surrounding environment. 10. A package according to claim 1, characterised in that it comprises two or more units (81) with a first and a second chamber. 11. A process for the production of a directly applicable mixture of two substances with the following steps: provision of a package (1) according to claim 1, wherein the second chamber (7) contains a second substance (9), exerting an external pressure on the first chamber (3), such that (a) the sealed joint between the films (11, 13) is selectively broken in said zone, (b) a passage channel (25) is formed between the first and the second chambers and (c) the first substance (5) is transferred from the first into the second chamber and is brought into contact with the second substance, piercing the cover film (13) in the zone (17) associated with the second chamber (7), which zone has a material weakening formed by a recess of a stabilising film (23) of the cover film (13) in the zone (17) associated with the second chamber, mixing of the first and the second substances before or after piercing of the cover film (13), dispensing the mixture of the first and second substances from the second chamber (7).
