A straight-edged blade vertically disposed and secured within a U-shaped support provides enhanced cutting abilities while protecting the operator from injurious contact with the blade cutting edges. The support is also adapted to allow easy removal of the blade after extended use without allowing excessive adhesive build-up on the cutting edge from adhering to the assembly. The blade is firmly maintained within the support via a spring tab which furnishes stability to the cutting assembly.Type: GrantFiled: December 14, 1988Date of Patent: July 31, 1990Inventor: John W.

Patent number: 4762586Abstract: Disclosed is a combined tape dispenser and hand-held tape applicator formed of a minimum of molded components designed for interlocking assembly without fasteners. The housing includes a handgrip lockable either in an extended position when employed to apply tape to a surface or in a retracted position when not in use or when used to dispense tape from a desk top support. The tape is mounted on a tape carrier normally biased to an extended tape-applicating position and manually retractable to expose a normally guarded cutting blade for severing the tape. While the carrier is moving between retracted and extended positions, a tape catcher clutches the tape reawardly from its free end and holds it captive with the free end thereof extending outwardly beyond the dispensing port in visible readiness for precise visible attachment to a surface to be taped.Type: GrantFiled: July 16, 1987Date of Patent: August 9, 1988Inventor: Robert C.

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 The cutting element is displaced in response to the movement of the withdrawn material by generating a displacement force, latching the cutting element against displacement in a normally guarded position in which the cutting element is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. Ruff, Albert Stubbmann

Patent number: 4516711Abstract: The invention concerns a dispenser of continuous, severable strips, of the kind with a case (1), a passageway (S) for the end of the strip and a cutting blade (16) provided with cutter means (16a). The dispenser comprises a first auxiliary blade (17) provided with a cover section (17a) applying friction to the strip and a stop section (17b) which during the severing operation is subjected to a pressure exerted by the cutting blade (16) and locks the strip at the cover section (17a); the dispenser also comprises a second auxiliary blade (18) protecting the cutter means (16a) when in the rest position and withdrawing behind the cutting blade when in the cutting position. The storage space (3) of the case can be designed to hold a continuous, accordion-folded strip.Type: GrantFiled: October 12, 1983Date of Patent: May 14, 1985Inventor: Jacqueline Barege

Patent number: 4427144Abstract: A plastic film dispenser comprising a support structure consisting of a housing (1), support means (26) for a roll of film, guide means in the form of a fixed flap (36) and a moveable flap (37) to guide film from the roll to an outlet (27). The housing is provided with a drop plate (34) moveable from a position where film being withdrawn is maintained clear of treated film severing means (41) to a position where film is contacted by the severing means. The housing preferably includes means (25) to support a roll of other material and a keeper rod (18) whereby a length of such material may be conveniently withdrawn from the roll and severed by severing means (12).Type: GrantFiled: May 5, 1981Date of Patent: January 24, 1984Assignee: EZY Wrap Products Pty. LimitedInventors: Wallace J. Macgrory, George C. Frederick

Patent number: 3991923Abstract: In an adhesive tape holder means a sheathing plate is mounted to one end of the means in vertically movable relation with respect to a cutting blade rigidly fixed adjacent to said end; the sheathing plate has a sliding element engaged with a cam mounted adjacent to said plate and having one end projected outwardly from one side of the means by a spring. When a pushing force is applied to said end, the cam is forced to move across the axis of the means to move down the sheathing plate, causing the blade to come out of the plate. When the force is released, the cam returns to its original position and simultaneously the sheathing plate moves up to sheathe the blade.Type: GrantFiled: March 4, 1975Date of Patent: November 16, 1976Inventor: Kenji Nishikawa

Patent number: 3972458Abstract: A paper holder for supporting a paper roll and for tearing it to a given length as it is reeled off the roll. The holder comprises a casing which rotatably supports a paper roll, and a retaining cover which is pivotally mounted on the casing at its one end. Casing includes a bearing surface over which a length of the paper web extends as it is reeled off the roll, and the retaining cover includes an abutment adjacent to its other end which bears against the bearing surface with the paper length interposed therebetween. Adjacent to its other end, the cover is also formed with a slot for passing the paper length upwardly therethrough. The paper length which is let through the slot is turned back and then allowed to hang down.Type: GrantFiled: September 15, 1975Date of Patent: August 3, 1976Inventor: Shotaro Hamada
