The packaging comprising an essentially dimensionally stable, elastically deformable external container, an easily deformable inner bag arranged therein, which receives the filling material, and a valve, is characterized in that the valve comprises a base body which extends over the opening of the external container and comprises at least one through opening for the filling material and a pin oriented away from the external container, and a cap which is fastened to the neck of the external container and covers the base body and the upper end wall of which is formed by a membrane which delimits a receiving chamber for the filling material between the cap and the base body and comprises an outlet opening for the filling material which in the unpressurized state of the packaging is closed by the pin in that the membrane with the area containing the outlet opening rests under preload on the pin, the membrane being lifted from the pin upon exertion of pressure on the external container by the pressurized filling material contained in the receiving chamber, so that filling material can exit, and that the cap comprises an air chamber which is separated from the receiving chamber for the filling material and sealed relative to the receiving chamber and the external container and which is connected via at least one hole through the wall of the external container to the intermediate chamber between the external container and the inner bag and via at least one venting valve to the exterior atmosphere.

1. Packaging comprising an external container that is substantially dimensionally stable in an initial state and that is elastically deformable, an easily deformable inner bag arranged therein, which receives filling material, and a valve, wherein the valve comprises a base body which extends over the opening of the external container and comprises at least one through opening for the filling material and a pin oriented away from the external container, and a cap which is fastened to the neck of the external container and covers the base body and the upper end wall of which is formed by a membrane which delimits a receiving chamber for the filling material between the cap and the base body and comprises an outlet opening for the filling material which in the unpressurized state of the packaging is closed by the pin in that the membrane with the area containing the outlet opening rests under preload on the pin, the membrane being lifted from the pin upon exertion of pressure on the external container by the pressurized filling material contained in the receiving chamber, so that filling material can exit,and that the cap comprises an air chamber which is separated from the receiving chamber for the filling material and sealed relative to the receiving chamber and the external container and which is connected via at least one hole through the wall of the external container to the intermediate chamber between the external container and the inner bag and via at least one venting valve to the exterior atmosphere,wherein the cap comprises a cylindrical inner wall on the inside of which a cylindrical inner wall of the membrane rests, which laterally delimits the receiving chamber for the filling material, andwherein the cylindrical inner wall of the membrane grips under the free end of the cylindrical inner wall of the cap and is locked in place behind an annular projection of the base body. 2. The packaging according to claim 1, wherein the membrane is injection-molded on the cap. 3. The packaging according to claim 1, wherein the base body rests on the edge of the container neck and is pressed by a surrounding shoulder of the cap thereagainst. 4. The packaging according to claim 1, wherein the cap is locked in place with hook-like inner projections under an outer bead on the edge of the container neck. 5. The packaging according to claim 1, wherein the cap is provided on its outer edge with a seal which engages into a surrounding groove in a shoulder of the external container or rests with preload on the shoulder. 6. The packaging according to claim 1, wherein the at least one venting valve is closed in case of overpressure in the air chamber and is opened in case of a negative pressure in the air chamber. 7. The packaging according to claim 6, wherein two diametrically opposed venting valves are formed. 8. The packaging according to claim 6, wherein each venting valve has a convex cross-sectional shape with respect to the air chamber, with a central cut extending in longitudinal direction and through the wall of the venting valve. 9. The packaging according to claim 7, wherein each venting valve has a convex cross-sectional shape with respect to the air chamber, with a central cut extending in longitudinal direction and through the wall of the venting valve. 10. Packaging comprising an external container that is substantially dimensionally stable in an initial state and that is elastically deformable, an easily deformable inner bag arranged therein, which receives the filling material, and a valve, wherein the valve comprises a base body which extends over the opening of the external container and comprises at least one through opening for the filling material and a pin oriented away from the external container, and a cap which is fastened to the neck of the external container and covers the base body and the upper end wall of which is formed by a membrane which delimits a receiving chamber for the filling material between the cap and the base body and comprises an outlet opening for the filling material which in the unpressurized state of the packaging is closed by the pin in that the membrane with the area containing the outlet opening rests under preload on the pin, the membrane being lifted from the pin upon exertion of pressure on the external container by the pressurized filling material contained in the receiving chamber, so that filling material can exit,and that the cap comprises an air chamber which is separated from the receiving chamber for the filling material and sealed relative to the receiving chamber and the external container and which is connected via at least one hole through the wall of the external container to the intermediate chamber between the external container and the inner bag and via at least one venting valve to the exterior atmosphere,wherein the cap is provided on its outer edge with a seal which engages into a surrounding groove in a shoulder of the external container or rests with preload on the shoulder such that the air chamber is tightly sealed relative to the exterior atmosphere,wherein the cap comprises a cylindrical inner wall on the inside of which a cylindrical inner wall of the membrane rests, which laterally delimits the receiving chamber for the filling material, andwherein the cylindrical inner wall of the membrane grips under the free end of the cylindrical inner wall of the cap and is locked in place behind an annular projection of the base body.
