Definitions

  • the invention relates to a letter folder lid produced in the adhesive lamination process using synthetic resin dispersion glue, in which a one-piece cardboard cover is provided with a one-piece plastic outer cover with edge flap and with a one-piece plastic inner cover without edge flap, but overlapping the folded-over edges of the plastic outer cover, and in which it is continuous plastic-covered letter folder cover is provided with continuous grooves from the outside on both sides of the letter folder back.
  • Letter folder lids are often provided with plastic covers on the outside and inside if higher demands are placed on the appearance and usability.
  • a one-piece cardboard ceiling of rectangular format is usually used, onto which a plastic outer cover is first glued on the outside.
  • the edges of the plastic outer cover which is congruent to the cardboard ceiling, but larger in terms of dimensions, are folded over and pressed on around the edges of the cardboard ceiling.
  • the inner plastic cover is then glued to the inside of the letter folder cover.
  • the dimensions of the plastic inner cover are somewhat smaller than the cardboard cover, but still so large that it overlaps the folded edges of the plastic outer cover. There are therefore areas in which the plastic outer cover is glued to the plastic inner cover by the synthetic resin dispersion glue.
  • Synthetic resin dispersion glues which contain synthetic resins dispersed in water, have proven themselves when a plastic cover is glued onto a cardboard box. However, they cause certain difficulties when two plastic covers ver together should be glued because the adhesive strength between two plastics is insufficient as long as there is still water in the glue. It usually takes several hours for two plastics to be reasonably firmly bonded to one another with the synthetic resin dispersion glue, and even then the usability with regard to the adhesive effect is lower than between plastic and cardboard.
  • So-called processing lines are often set up in the manufacture of letter folder lids, i.e. the individual operations are carried out quickly on successive machines. There is no time to allow the resin dispersion glue to harden completely before the next step after the plastic covers have been applied to the cardboard ceiling.
  • the invention has for its object to avoid the disadvantages mentioned in the letter folder cover described above and to ensure that the glue points between the plastic outer cover and the plastic inner cover are sufficiently firm even during further processing of the letter folder cover.
  • the invention consists in that the plastic inner cover has a recess in the area of the groove at its edges.
  • the plastic inner cover is left out in those places where it does not stick properly when processing the letter folder cover.
  • the invention is based on the finding that a little further from the edges of the plastic inner cover, the stretching of the plastic inner cover due to the grooving is just so much less that there is still sufficient adhesion between the two plastic covers during further processing of the letter folder cover .
  • the recess can be designed in detail as described in the subclaims.
  • a total of four such recesses are provided on the plastic inner cover, which can have the same dimensions to each other.
  • the recesses are made on the plastic inner cover even before the synthetic resin dispersion glue is applied.
  • the letter folder cover (1) shown in Fig. 1 consists of the side parts (2 and 3) and the letter folder back (4), each of the side parts (2 and 3) through a continuous groove (5 and 6) made from the outside ) is divided. These grooves (5 and 6) are required for one-piece letter folder covers (1) so that the side parts (2 and 3) can be pivoted relative to the letter folder back (4) when using the letter folder.
  • the finished letter folder later receives a finger hole (7) on the letter folder back (4) and further parts not shown in FIG. 1.
  • the letter folder cover (1) receives its stability from a cardboard cover (8) which is in one piece for the entire letter folder cover (1).
  • a plastic outer cover (9) is glued onto the side of the cardboard cover (8) assigned to the outside of the letter folder cover (1).
  • a synthetic resin dispersion glue is used for this in the manner already explained.
  • the cut for the plastic outer cover (9) is congruent with regard to the cut of the cardboard cover (8), but is somewhat larger in size.
  • the Edges (12 and 13) are folded and brushed around the edges (10 and 11) of the cardboard cover (8) in a separate operation.
  • the plastic inner cover (14) is then glued onto the side of the cardboard cover (8) assigned to the inside of the letter folder cover (1), in such a way that it covers the folded edges (12 and 13) of the plastic outer cover (9) in areas (15 and 16) overlaps. Overall, the cut of the plastic inner cover (14) is also congruent with the cut of the cardboard cover (8), but its dimensions are somewhat smaller than this.
  • the top view from the inside of the letter folder cover (1) according to FIG. 3 shows how the plastic inner cover (14) overlaps the four existing folded edges (12, 13, 17 and 18) of the plastic outer cover (9), specifically with Overlap areas (15, 16, 20 and 21).
  • the plastic inner cover (14) itself has edges (22, 23, 24 and 25).
  • the synthetic resin dispersion glue is somewhat problematic in the overlap areas (15, 16, 20 and 21), as has already been explained in the introduction to the description.
  • the points at which the edges (22 and 23) of the plastic inner cover (14) cross the respective groove (5 and 6) are particularly critical.
  • the plastic inner cover (14) detaches from the plastic outer cover (9) in this area, since normally during the manufacture of the Grooves (5 and 6) the synthetic resin dispersion glue is not yet hard enough. A little further away from the edges (22 and 23), i.e.
  • the invention takes advantage of this fact and provides that in the intersection areas of the edges (22 and 23) with the grooves (5 and 6) recesses (26) are provided, which the Have the shape of small rectangles and are provided with curves (27). It is provided that the width (B) of the recesses (26) corresponds approximately to 3 times the width (A) of a groove (5 or 6), while the depth (T) of the recesses (26) corresponds approximately to 1 to 2 times that Width (A) corresponds to a spline (5 or 6).
