Patent number: 6524022Abstract: A paper cutter includes a blade extending in the width of a rolled paper, the blade having a linear edge and a serrated edge formed at an end of the linear edge. A paper guide for discharging the paper is disposed downstream from the cutter, the paper guide having an upper and a lower member and a discharge port at the downstream end thereof. A cutout section is formed at the upper member of the paper guide, and the position of the cutout section corresponds to the serrated blade edge in the width direction of the paper. The cutout section permits the paper to be grasped with fingers by the operator. When the paper is pulled, a force acts on the paper in a direction to press it against the serrated blade edge, cutting the paper from the edge.Type: GrantFiled: December 26, 2000Date of Patent: February 25, 2003Assignee: Seiko Epson CorporationInventors: Masahiro Minowa, Naoki Kobayashi

Patent number: 6491198Abstract: A cutting assembly for plastic film or other sheet wrapping material dispensers. The cutting assembly comprises a member having a length corresponding to the length of the dispenser box, and a U-shaped cross-section adapted to slip over the free edge of the front panel of the dispenser box. The member has a base web with one leg on the inside of the box and a second leg exposed on the outside of the box. The legs meet the web in curved shoulders, diverge downwardly and outwardly, and have extending flaps at their lower ends which are curved back internally of the U-shaped member to provide retainer edges which project angularly upward and inward of the U-shaped member to resist upward displacement of the member from the panel. The proportions of the inwardly curved flaps and the distance between them are such that there is no possibility of the leg or legs of one cutting blade interlocking with the leg or legs of another cutting blade.Type: GrantFiled: November 12, 1999Date of Patent: December 10, 2002Assignee: Metal Edge International, Inc.Inventor: Armin C.

Patent number: 6491082Abstract: A safety for blade of tape dispenser includes a fixing seat provided above a tape roller of the tape dispenser. The fixing seat defines an inner space in which a blade of the tape dispenser is fixedly mounted and a shield plate is disposed above the blade. The shield plate includes two legs configured to have some degree of elasticity and connected at outmost ends to the fixing seat to normally project a front edge of the shield plate beyond a serrated front edge of the blade when the tape dispenser is not in use or is used to apply a length of tape on a surface. When the tape dispenser is used to cut the length of applied tape, the two elastic legs allow the shield plate to slide backward under a tension of the tape to expose the blade for cutting the tape.Type: GrantFiled: January 23, 2002Date of Patent: December 10, 2002Inventor: Sheng Mei Fu

Patent number: 6418995Abstract: A dispenser from which sheet material may be manually pulled from a supply of the sheet material carried on the dispenser through a passageway defined by a frame of the dispenser. The dispenser includes a cutting member having a sharp cutting edge adapted for transversely cutting the sheet material and an elongate contact surface generally parallel to and spaced from the cutting edge. The cutting member is mounted on the frame for movement between (1) a retracted position to which it is biased at which the cutting edge is positioned to restrict contact between a person using the dispenser and the cutting edge and at which the contact surface extends along the one side of the passageway—and (2) a cutting position to which the cutting member can be moved from its retracted position by manually tensioning sheet material being pulled from the dispenser around the contact surface of the cutting member.Type: GrantFiled: March 21, 2000Date of Patent: July 16, 2002Assignee: 3M Innovative Properties CompanyInventors: Philip V. Sadrakula, Leonard Kampa, James F. Pitzen

Patent number: 6405913Abstract: A paperboard carton for storing and dispensing a roll of web material, such as plastic film, foil, wax paper, etc. has a plastic (e.g. polystyrene) cutting blade that is adhered to an inside front lip of the paperboard carton lid. The polystyrene cutting blade preferably has a thickness of about {fraction (20/1000)} of an inch, and preferably contains aggressive teeth at the ends of its serrated edge to help initiate tearing of the web material. The aggressive teeth are larger in size than the remaining teeth of the serrated edge. Use of the polystyrene cutting blade allows for increased production rates without compromising performance.Type: GrantFiled: December 22, 1999Date of Patent: June 18, 2002Assignee: Green Bay Packaging, Inc.Inventor: Phillip L. Passamoni

Patent number: 6367533Abstract: A cut-off blade assembly including a thin metal blade having an attachment portion by which the cut-off blade assembly can be attached to a dispenser, and a plurality of projecting similarly shaped triangular primary teeth. The triangular primary teeth each have two sides terminating in points and have bases adjacent the attachment portion that are aligned in a first direction along the blade so that their points project generally at right angles to that first direction. Edge surfaces on the sides and at the points of the primary teeth intersect a major surface of the primary teeth at an included angle of no greater than about 90 degrees to define a cutting edge at that intersection. The cut-off blade assembly further includes projections along one major surface of the primary teeth.Type: GrantFiled: July 21, 1999Date of Patent: April 9, 2002Assignee: 3M Innovative Properties CompanyInventor: James F.
