Definitions

  • the invention relates to a folding box, preferably made of a one-piece cardboard blank, with a longitudinal seam and closure flaps arranged on both end faces, two of which oppose one another at least partially overlap and in which a tear strip formed by perforation is provided.
  • folding boxes of this type are known in which a part of one of the closure flaps has two perforations. lines is divided, whereby a tear strip is formed.
  • one of the perforation lines is very close to the hinging line of the flaps.
  • the perforation line is inevitably bent, even if to a lesser extent, and the remaining webs between the perforations are thus stretched.
  • the strength of the perforation line is thus reduced considerably, the extent of the reduction being unknown.
  • this flap is no longer flat.
  • the invention has for its object to design a folding box of the type mentioned in such a way that the disadvantages described are avoided.
  • This object is achieved in that the entire overlap area of the two mutually overlapping flaps is divided by a perforation.
  • the distance between the articulation line and the perforation line of the respective closure flap hereby has the greatest possible dimension; which has the least impact on the perforation line when folded.
  • FIG. 1 in FIG. 1 denotes a cardboard blank which has a top wall 2, a bottom wall 3 and two side walls 4 and 5.
  • a narrow strip 6 is articulated on the bottom wall 3 and is connected to the side wall 4 in a longitudinal seam.
  • flaps 7 to 16 are hinged to the walls via fold lines.
  • the flaps 8 and 10 or 13 and 15 are hinged to the top wall 2 or bottom wall 3 and slightly overlap one another in the erected state of the folding box. In the case of the two closure flaps 13 and 15, this overlap area is divided by a perforation line 17 and 18, respectively.
  • a cardboard blank 21 is again equipped with a top wall 22 and bottom wall 23 as well as side walls 24 and 25 and a strip 26.
  • the side walls 24 and 25 are made very narrow, which results in a relatively flat folding box when erected.
  • flaps 27 to 32 and 34, 36 are hinged to the walls via fold lines (not shown).
  • Sealing flaps 33 and 35 are formed on the top wall 22 and the bottom wall 23 for opening the folding box.
  • the connecting lines between these two walls and the flaps are designed as perforation lines 37 and 38, respectively.
