Definitions

  • the present invention is framed in the field of the art of manufacture of envelopes for sending letters or documentation, especially flat envelopes the lateral edges of which have a uniform thickness, even in the area of the closing tab.
  • envelopes capable of feeding an automatic enveloping machine that introduces the documentation in its interior at high speed, without human intervention.
  • This type of envelopes have a rear surface, joined by a bending line with a front surface, which extends in a closing flap, separated from it by a transverse line, parallel to the above and perpendicular to the edges of said surfaces.
  • the edges have a flap of the side, which is introduced between both surfaces, or on top of the rear surface, sticking all of them during the manufacturing process, to achieve the closure of the envelope by the edges.
  • the rear surface is shorter or has a cut in the mouth, usually trapezoidal, which opens up towards the centre, which facilitates the introduction of the documentation on the inside, both manually and automatically.
  • the rear surface normally has a trapezoidal configuration, the largest base of which is situated on the base and the smallest one coincides with the mouth; this configuration is adopted to prevent that a small mismatch in the formation of the envelope causes the slightly protrusion of this surface by one of the sides and which causes, in addition to an unsightly effect, a jam in the enveloping machine.
  • the conventional envelopes have a problem for their storage and transport given that all of them are stacked or annexed in the same position and, while there are three overlapping surfaces at the edges, in the area where the flap is situated on top of the edges there are four overlapping surfaces, what causes the stack to bow, or that when introducing them in a box or forming a package with them the envelopes are tightened by the part corresponding to the location of the flaps, while by the other parts are formed gaps that facilitate the bowing and even the slightly bending of the envelopes with transport.
  • the envelopes that are subsequently subject of the printout have been manufactured with a small flap located on the vertices opposite to the closing flap, i.e. at both ends of the base of the envelope, making it easy to keep a column of envelopes of this type vertically and preventing it from twisting while lifting the side corresponding to the closing flap more than the side that forms the base or bottom of the envelope.
  • the envelope object of the invention conveniently solves both problems, on one part it is a flat envelope, insofar as its side edges have identical thickness along their entire length, since it has the same number of paper surfaces.
  • the envelope behaves in the stacking, or when forming a package of envelopes, all of them placed in the same position, as an element that has a more rigid frame, which are the two side edges and an intermediate surface slightly lighter since it has one or two less paper surfaces than said edges.
  • This envelope has, on the sides of both the front surface and the rear surface, two side flaps.
  • the flaps of the front surface are slightly wider than two side flaps on the rear surface.
  • the respective flaps on each side are separated from the front and rear surfaces by two bending lines, which define the edges in the formation of the envelope. Likewise, the flaps on each side are separated by two "V"-shaped cuts, the vertices of which coincide with the transverse line that separates the front and rear surfaces and with the corresponding side line.
  • the sheet that forms an envelope has two cuts affecting the flaps on the rear surface, by the areas corresponding to the free ends, next to the mouth of the envelope, that have a length at least equivalent to the sides of the closing flap, such that when making up the envelope they are located on top of said cuts.
  • the envelope is formed by folding the front and rear surfaces over themselves and subsequently the respective side flaps over the rear surface and adhering the set of all the surfaces to close the edge of the envelope.
  • This solution allows eliminating the side interior tabs that the conventional envelopes typically have, which prevents the possible jam in the enveloping machine when introducing the sheet or sheets in the interior of the envelope since they never bump into these tabs because they are not present.
  • the edge is delimited by the folding of the outer flap that goes from the front surface to the top of the rear surface, the edge is sharp and uniform, whereby the package of envelopes and the own envelope itself are more aesthetic since there are no partial cuts in its edge.
  • this envelope has a rear surface (2), provided at the free end with a recess or cutting (C3), which forms the mouth of the envelope.
  • Said rear surface is joined by a bending line (L1) with a front surface (1), while this is prolonged in the closing flap (3), which is separated from said front surface by a transverse line (L2), parallel to the previous line (L1) and both are perpendicular to the edges of said surfaces.
  • the front surface (1) has two side flaps (4a and 4b) which are slightly wider than the flaps (5a and 5b) existing on the rear surface (2).
  • the rear surface (2) has two side flaps (5a and 5b), slightly narrower than the side flaps (4a and 4b) existing on the front surface (1) as already mentioned.
  • the flaps (4 and 5) existing respectively on the front and rear surfaces are separated from them by bending lines (L3a and L3b), which define the edges of the envelope in the conformation of the same.
  • the flaps (4 and 5) of each side are separated by two "V"-shaped cuts (C1a and C1b), the vertices of which coincide with the transverse line (L1) that separates the front and rear surfaces, and with the corresponding side line (L3).
  • the flaps (5a and 5b) have two cuts (C2a and C2b) affecting the areas corresponding to the free ends, next to the mouth of the envelope. These cuts have a length at least equivalent to the sides of the flap (3), such that when making up the envelope it is located on top of said cuts, such that throughout the length of the edges the envelope has four overlapping surfaces and no more at any point, whereby envelopes having uniform thickness in these side bands are achieved, such that when stacking them or forming a package with them, they will not turn vertically or sideways.
  • the envelope such as shown in figure 2 is formed by folding the front (1) and rear (2) surfaces over themselves and subsequently the respective flaps (5 and 4) over the rear surface (2) and adhering the set of all the surfaces (1-2-5-4) closing the edge of the envelope.
  • This solution is suitable in those cases in which the envelopes are intended for being automatically enveloped.
