Definitions

  • the present invention relates to an envelope for correspondence to tear open without using any cutting or tearing instrument.
  • the object of the invention is instead to obviate said inconveniences by means of a combina­tion of elements which will be speficied here under with reference to the enclosed drawing, where:
  • envelope 1 is represented which may be of any size or dimension according to the invention.
  • the envelope is closed by a flap 2 presenting an intermediate area 3 which is weakened by a number of small cuts obtained by punching or some other suitable means.
  • a rib 4 made of an adhesive is applied to rein­force the paper by forming a kind of strip.
  • the envelope is closed, to open it it is enough to grasp (see Fig. 2) the precut and weakened areas 3, 3′ and tear the paper upwards.
  • the stiff rib 4 will then act as a cutter and thus allow an easy and correct opening of the envelope without using a paper-knife or the like.
  • rib 4 may be applied to any side of the envelope during its manufacture, without surpassing the limits of the invention.
