ABSTRACT:
A cutting blade is formed from a rectangular sheet of a rigid material such as metal or plastic. One side of the sheet is formed into a roll or tube giving structural rigidity to the entire cutting blade. The remainder of the sheet extends flat and tangentially from the tube. In cross section, the cutting blade looks generally like the arabic numeral "9". At the top ("rounded head portion") of the "9", a series of holes in one or more rows are punched through the cutting blade so that petals of metal project up and out of the "9" shape at its top. Preferably, for each hole, associated petals are pointed in different directions to provide both a cutting edge and a holding edge for film cut with the blade. The cutting blade may include a series of tangs pointing up (toward the top of the "9") which allow the blade to be easily placed over an edge of the dispenser, but not easily removed therefrom. The blade may be placed on a flat, unfolded insert (of cardboard or a similar stiff material) for a conventional cardboard roll dispenser carton, the insert then inserted between the opening flap and a front edge of the carton, and the head of the "9" shaped blade used as a latch to hold the dispenser cover closed. The petals of the holes may be surrounded with protective bumps to further avoid any possibility of scratching a user of the dispenser.
