ABSTRACT:
A tear out opening member or flap for use with paperboard cartons and the like comprises a paperboard substrate having an upper surface and an opposed lower or undersurface. The substrate includes a first cut portion disposed on the upper substrate surface and penetrating the upper surface to a point intermediate the thickness of the substrate. A second cut portion is disposed on the undersurface of the substrate, the second cut being spaced apart from the first cut and enveloping the first cut. Alternatively the disposition of first and second cuts may be reversed such that the first cut envelopes the second cut. The second cut penetrates the undersurface to a point intermediate the thickness of the substrate. Spaced apart reinforcement hinge members are disposed along the second cut at a predetermined angle thereto.
