Abstract
For separate waste utilization of the plastic and cardboard parts of a used packing container (1), the cardboard sleeve (5) reinforcing its circumferential wall (2) and only positively connected thereto has a desired separation strip (10), whose operation leads to the separation thereof. The desired separation strip (10) is formed on the overlap area of the cardboard sleeve (5). It only has one weakening line (16) bounding it on one side and concealed by the overlap. On tearing, the inner overlap edge (13) acts as a cutting edge for the outer overlap layer.
