  • Cutter for dispensing container and dispensing container provided with said cutter
    Patent number: 4679718
    Abstract: A cutter has a file-like coarse surface formed on a substrate by fast adhesion of irregular granules to the surface of the substrate with a soft adhesive agent. A dispensing container has the cutter attached fast thereto. The cutter can be folded and attached fast to a ridge of a dispensing container, the ridge in a position such that a sheet material drawn out of the dispensing container will be pressed most readily, without sustaining a crack in the layer of adhesive agent and inducing unwanted separation of irregular granules from the substrate.
