A cutting blade may be fixed to or integrally formed with the dispenser. Inwardly projecting shoulders are fixed to the front bottom surface of the side walls in opposing spaced relation and serve to spread the side walls apart as the tape dispenser and cutter is pressed down over a roll of tape. As the shoulders clear the inner core of the tape roll, the shoulders are snapped back beneath the core of the roll and serve to retain the invention on the roll of tape.Type: GrantFiled: January 21, 1987Date of Patent: December 8, 1987Inventor: Rod W.

Patent number: 4679718Abstract: 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.Type: GrantFiled: March 24, 1986Date of Patent: July 14, 1987Assignee: Asahi Kasei Kogyo Kabushiki KaishaInventors: Hisao Kai, Kensuke Ochiai, Takeshi Niisato

Patent number: 4586639Abstract: A free end portion of sheet wrapping material is grasped and pulled from a dispenser transversely past and spaced from a cutting element mounted on a housing. The cutting element is displaced in response to the movement of the withdrawn material by generating a displacement force, latching the cutting element against displacement in a normally guarded position in which the cutting element is inoperative for cutting, and thereupon unleashing the displacement force in response to a further movement of the material to drivingly displace the cutting element from the guarded position to a cutting position in which the cutting element is in a position to sequentially pierce and cut the sheet material that is subsequently moved toward the same. Methods of dispensing the sheet material and of wrapping items also are disclosed.Type: GrantFiled: July 20, 1984Date of Patent: May 6, 1986Assignee: Clik-Cut, Inc.Inventors: Stanley L.
