  • Patent number: 5732868
    Abstract: A generally cubical cardboard container is provided for containing and storing a length of sheet-like material which may be drawn via an elongate slot in a top face of the container and over an uppermost edge portion of a front face of the container. A safe cutting element, preferably formed of a substrate bearing small sharp-edged particles, is adhered to the uppermost edge portion of the front face. A waterproof coating is provided to coat the sharp-edged particles, and protects them from any ambient moisture and/or grease and also ensures against removal of any particles during use. The user simply draws out a desired length of the sheet-like material through the slit and over the uppermost edge of the front face, and then applies a downward force to press the material to the sharp edges of the coated particles to initiate and continue a tear across the width of the material.
