Definitions

  • the invention relates to a folding box with an inner bag inserted according to the preamble of the main claim.
  • a disadvantage of these known folding boxes is the fact that they do not open, at least not evenly, with lateral pressure on the middle folding line. Automatic further processing of the stacked flat folding boxes is therefore ruled out. In addition, the bag is heavily loaded during filling and often breaks open.
  • the invention is therefore based on the object of designing a generic folding box with an inserted inner bag in such a way that it is reliably tight, can be automatically processed further and when the folding box is opened the bag type with the best volume utilization (block bag) is directly completely - also in the bottom - opened.
  • This object is achieved according to the invention in a generic folding box by its characteristic features.
  • the special design of the block bottom bag and its specific type of gluing into the folding box ensures that with minimal lateral pressure on the center folding lines of the folding box, the latter opens without any force counteracting the opening movement when the block bottom bag is unfolded because the block bottom bag is unfolded Condition completely in the folding box, the four inner sides and the bottom of which are tight and without space. It must only the force required to unfold the bag can be applied so that it can unfold freely.
  • the unfolded bag then firmly and without space in between the bottom and the four inner sides of the folding box also gives off the forces that occur when it is filled, directly to the stiffer folding box, so that the inner bag remains sufficiently reliably sealed and does not tear.
  • the folding box designated as a whole by 5 has a cuboid shape in the finished folded state with four mutually parallel folding lines 6, 7, 8, 9 as edges.
  • a transverse fold 14 or 15 running perpendicular to the fold lines 6 to 9 is provided in the upper and lower region of the folding box 5.
  • the bag designated overall by 16, is a so-called block or block-bottom bag, which corresponds exactly to the interior of the folding box in terms of its dimensions, width and depth when unfolded.
  • the flat block bottom 17 (FIG. 3) is folded down in a V-shape along its line of symmetry 20 to form two parallel and equally large bag flat sides 18 and 19.
  • the bag 16 is placed congruently on one of the inner sides 21, 22 of the without the middle folding lines 12-, 13 that the lower end 23, 24 of each flat side of the bag 18, 19 ends at the lower transverse fold 15 of the folding box 5.
  • each flat side of the bag 18, 19 is glued in the area 25 of the inside, preferably in the edge area thereof, which is defined on each inside 21, 22 without the middle fold lines 12, 13 between the upper and lower transverse folds 14, 15.
  • the actual area provided with adhesive is shown hatched in FIG. 1 and designated 26 and 27, respectively.
  • the bag 16 lies here in Figure 1 on the inside designated 21.
