  • Patent number: 5203492
    Abstract: For a separate waste disposal of the aluminum foil inner coating (9) of a packing container produced in a winding process, the overlapping foil edges (16, 17) are only glued together at a distance from a foil outer edge (18). The unglued overlapping foil edge (21) makes it possible to peel the inner coating (9) from the cardboard body, after removing the bottom diaphragm of the packing container. The peeling movement starts on removing the bottom diaphragm, in that its rim is glued to the unglued, overlapping foil edge. A gripping tab is provided on the bottom diaphragm to permit the removal thereof.
