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.

Claims

1. A packing container comprising:

a plastic container having a top rim, a circumferential wall, and a bottom portion; and

a cardboard sleeve surrounding said circumferential wall of said plastic container, said sleeve being formed from a cardboard blank having an upper edge, a lower edge, and inner and outer overlapping edges, said sleeve having a predetermined separation strip and a gripping tab, said predetermined separation strip being formed by said inner and outer overlapping edges being spaced apart to define an overlap area having an inner overlap area and an outer overlap area, said inner overlap area having a weakening line positioned laterally of said inner overlapping edge, said strip at least partially spanning said upper edge and said lower edge of said sleeve, said gripping tab being located at the upper edge of said strip, whereby said sleeve is separated from said plastic container by pulling down on said gripping tab and tearing said separation strip away from said sleeve.

2. The packing container according to claim 1, wherein said weakening line is covered by said outer overlap area, such that said inner overlap area said predetermined separation strip is narrower than said outer overlap area.

3. The packing container according to claim 1, wherein said circumferential wall has in the vicinity of said top rim, a circumferential step, said outer overlap area being set back from said top rim, said step defining an angular cutout of said cardboard blank, wherein said gripping tab is formed by the portion of said inner overlap exposed by said angular cutout.

4. The packing container according to claim 3, wherein said top rim of said plastic container has an outwardly projecting flange, and said upper edge of said sleeve is directly adjacent to said flange except in the vicinity of said gripping tab, said gripping tab being bounded circumferentially on one side by said inner overlap edge and on the other side by an incision on said cardboard sleeve running parallel to said inner overlap edge.

5. The packing container according to claim 4, wherein said incision is collinear with said outer overlap edge.

6. The packing container according to claim 4, wherein said gripping tab overlaps said step.

7. The packing container according to claim 1, wherein said separation strip is bounded by two separation lines, wherein one is formed by said weakening line on said inner overlap area and the other, provided on said overlap area, is defined by said inner overlap edge running beneath it.

8. The packing container according to claim 1, wherein said outer overlap area has a starter portion formed by an incision on said cardboard sleeve.

9. The packing container according to claim 4, wherein said upper edge of said sleeve has rounded corners in the vicinity of said gripper tab and said gripping tab (18) has rounded corners.
