Definitions

  • the present invention relates to an improved small size paper cutter for letter opening.
  • the cutter is provided with a cutting angle and a guide member, and the cutting edge is protected through members that are external to the cutter.
  • the object of the present invention is to improve said cutter, by realizing it with a simpler construction, such as to allow for the incorporation thereof into coupled rigid thin bodies, e.g. plastics covered cards, or into a similar plastic material rigid body, at the same time conferring a protection for the cutting edge, thus realizing an improved small size cutter that is simple and safe.
  • the improved cutter for letter opening realized according to the invention, thanks to the design simplicity, provides for a cutter that is extremely thin and tiny, adapted to be used in a great number of ways.
  • said small size cutter can be fitted to different articles such as a ruler, a pen cap, a stationery article, and so on, either parallel or perpendicular to the article.
  • the subject small size cutter substantially consists of a cutting blade body either sandwiched between two thin rigid sheets coupled together, or embedded in a body of rigid plastic material, also thin, positioned at the bottom of an open slit and forming with such slit an acute cutting angle; the guide member being formed by the wall of the slit itself, which slit constitutes an effective protection member for the cutting edge of the small size cutter, thanks to the above placement thereof in the cutter.
  • the small size cutter substantially comprises a blade body 1, with a sharp edge at 3, either sandwiched between two thin rigid sheets 5 coupled together, or embedded in a body 7 of rigid plastic material, also thin, positioned at the bottom 9 of an open slit 11, and forming with such slit an acute cutting angle.
  • the guide member of the body 7 (or 5) of the small size cutter, and therefore of the small size cutter itself, is formed by the walls 13 of the open slit 11.
  • Said slit 11 thanks to the placement of the blade body 1 provided at the bottom thereof, constitutes an effective protection member for the cutting edge 3 of said blade body 1 of the small size cutter.
  • Fig.s 4 and 5 it is shown an application of the small size cutter according to the invention at the end of a pen cap or the like.
  • the body 7 which is of course thin and tiny, and already embeds the blade body 1 of the small size cutter, is applied spaced from the wall 15 of the cap, such wall being substantially parallel to the body 7 of the small size cutter so as to make easier its insertion into the envelopes to be opened, which would otherwise be difficult.
