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.
Claims22
A packing container with a container body, which is closed at one end (4) by a bottom diaphragm (3) and at its other end (6) by a lid diaphragm (5), the container body (2) having an inner coating (9) of a material which is of a different type from that of an outer coating (14) and is of the same type as the material of the bottom diaphragm (3) and said inner coating (9) extending helically with overlapping edges (16,17;
- 16',17';
- 16",17") on the container body (2), the bottom diaphragm (3) having a rim which is connected to a strip of the inner coating (9) and the overlapping edges of said strip are superimposed in a contact-free manner at least in an outer marginal area (21,21',21"), the bottom diaphragm (3) carrying a grip, so that upon tearing out the bottom diaphragm (3) the strip of the inner coating is detached from the outer coating for separate waste disposal.
A packing container body comprising:
- a body and an inner liner made of a material different than said body, said liner extending helically with overlapping edges in said body, said body having a diaphragm attached to an end of said body, said diaphragm having a rim which is connected to said liner, said overlapping edges being at least temporarily in contact with each other in a region which is spaced a predetermined distance from an overlapping edge facing an interior of the container body to facilitate the removal of said liner from said container body when said diaphragm is torn out for waste disposal.
