Definitions

  • the invention relates to an envelope, mailing bag or the like, consisting of a sheet-like blank made of an opaque and at least largely tear-resistant material, which is glued by folding, via a bottom flap and a side flap and has a flap with a strip-shaped adhesive layer, which for Closing by folding the closure flap on an opposite surface, if necessary also provided with a strip-shaped adhesive layer, can be brought to bear on the back of the finished blank.
  • Envelopes, mailing bags or the like are made from sheet-like blanks, which are usually separated from a roll.
  • the sheet-like blank consists of an opaque material which, depending on its purpose, must be tear-resistant or largely tear-resistant.
  • Tear-resistant or largely tear-resistant blanks for envelopes and mailing bags mainly consist of paper reinforced with a textile fabric or of a plastic film with a fibrous structure, in which very thin olefin fibers are produced by a melt spinning process and are sprayed irregularly onto a base. Then it turns out This sprayed plastic fibers using pressure and temperature, that is, without additional binder, formed a film with a fibrous structure.
  • Such a tear-resistant plastic film is sold by the "Du Pont Company", USA, under the trade name "Tyvek”.
  • An envelope, a mailing bag or the like is then formed from each sheet-like blank by folding, whereby a bottom-like flap and a side flap, which can also be located in the middle of the back, are used to glue the bag-like body.
  • the blank also has a closure flap which is provided with a strip-shaped adhesive layer.
  • the sealing flap is then folded against the back, the strip-like adhesive layer coming to rest on a counter surface of the back.
  • the counter surface can also be provided with a strip-shaped adhesive layer which interacts with the adhesive layer of the closure flap.
  • Adhesive closures of this type have the advantage in the case of envelopes, mailing bags or the like made of tear-resistant material that the closure can be opened and, if appropriate, closed again by “opening”. However, this means that the recipient of such envelopes or mailers can never be certain whether an unauthorized opening has taken place and the content has been read or at least part of the content has been removed.
  • the invention is therefore based on the object of designing an envelope, a mailing bag or the like from an at least largely tear-resistant material with an adhesive closure in such a way that after opening - whether authorized or unauthorized - the closure flap can no longer be closed.
  • This perforation means that when the envelope or mailing bag is opened, the counter surface is separated from the back by the high adhesion of the adhesive layer (s). This means that such an envelope or mailing bag can no longer be returned to its original, closed state and any unauthorized opening can be recognized immediately.
  • Such a perforation also has the advantage that the envelope or mailing bag can be opened easily without having to overcome the adhesive force of the adhesive layer (s).
  • an envelope 1 is shown from the back, which was produced, for example, from a blank, known per se, from a film material with the trade name "Tyvek” from the company "Du Pont Company", USA.
  • This envelope was formed in a manner known per se from a sheet-like blank by folding and glued to the envelope 1 via a side flap 2 and a bottom flap 3.
  • These adhesive seams are usually designed so that they cannot be opened without destroying the envelope 1.
  • the envelope 1 has a flap 4, which is provided with an only indicated, strip-shaped adhesive layer 5 made of a known adhesive material.
  • the counter surface 6 on the back of the envelope 1, on which the adhesive layer 5 comes to rest when the envelope 1 is closed by folding the sealing flap along an indicated line 7, can also be provided with a strip-shaped adhesive layer 8.
  • these two adhesive layers 5, 8 come to cover over the entire surface.
  • the counter surface 6 of the back of the envelope 1, on which the strip-shaped adhesive layer 5 to bear comes and which is optionally also provided with a strip-shaped adhesive layer 8, is separated by a perforation 9 from the remaining part of the back of the envelope 1.
  • this perforation 9 is formed by incisions 10, which for example can have a length of 1.0-5.0 mm, advantageously 3.0 mm.
  • These incisions 10 are spaced one behind the other and separated from one another by webs 11. The length of these webs is, depending on the material of the envelope 1, about 0.5-2.0 mm, for example 1.2 mm.
  • This perforation 9 which delimits the counter surface 6 associated with the adhesive layer 5 of the closure flap 4, now leads to a properly sealed envelope 1 when the closure flap 4 is pulled up due to the adhesive forces, so that the closure flap 4 does not detach from the counter surface 6, but rather that Mating surface 6 is separated from the back of the envelope 1.
  • An envelope 1 designed in this way can therefore no longer be properly closed after it has been opened - be it authorized or unauthorized - so that at least every unauthorized opening can be recognized immediately.
  • this perforation 9 facilitates the authorized opening process.
  • the perforation 9 by means of circular or slot-like punchings which are likewise spaced apart from one another or are separated from one another by webs.
  • Adhesive material such as the closure flap 4 is closed
  • a counter surface delimited by such a perforation can also be provided in the region of the side flap 2 and / or the bottom flap 3.
  • the envelope can also consist of another tear-resistant material, for example paper reinforced with a textile fabric, reinforced cardboard or the like.
