Definitions

  • the invention relates to a cuboid gable packing for bulk goods according to the preamble of claim 1.
  • Such a pack is known from practice (Tetra Brik® - pack of the A B Tetra Pak x).
  • Another gable package is shown in German laid-open specification 21 58 076.
  • a gable pack when the double-lying triangular folding flaps are folded around the respective lateral Kinckkante of the package body so high tensions in the outer layers of the folded seam, that so-called bridge seam breaks across the bridge seam are the result.
  • the reasons for this are partly the unfavorable course of the fiber direction of the carrier material of the composite material (fiber course in the direction of the crease edge), the composite thickness of the composite material (carrier material in connection with sealed PE foils and in special cases laminated aluminum foil), the sealing process used and the fact look for five bonded layers in the area of the crease.
  • these gable-top packs are made from a pre-grooved pack cut by breaking all the groove lines once before the final pack creation and bringing them back to their original flat position, sharp-edged groove line projections remain due to the pre-breaking, especially with aluminum-laminated cuts on the inside of the pack.
  • the plastic coating of the blank is particularly in the crease cross, i.e. at the point where the longitudinal body groove lines and the cross seam base line running transversely at the upper cut edge intersect when shaping and flattening the cross seam, so that in the finished package the filling material can penetrate into the composite material, thereby contaminating the interior of the package and the Filling material takes place, the desired long-term shelf life of the filling material lapses.
  • the invention has for its object to design and refine a gable package according to the preamble of claim 1 so that, on the one hand, bridge seam breaks in the triangular folding flaps carrying the bridge seam, which are folded onto the narrow side of the package, are avoided and, furthermore, the creased cross breaks are suppressed and, on the other hand, the durability of the Web seam closure is reliably guaranteed in its original form without the inner polyethylene layer being damaged when the web seam is shaped and laid flat.
  • EP-B 0 027 668 describes this a pack laminate with lines of weakness.
  • a weakening line which forms a fold line in the laminate during the formation of the pack, has an interruption and in the region of this interruption two auxiliary grooved lines are arranged, which are located in the main direction of the weakening line on both sides of the extension of the weakening line to the bond in to loosen up this area completely.
  • the provision of two auxiliary groove lines is complex on the one hand and on the other hand leads to a loosening of the laminate composite taking place in a firmly delimited area.
  • the second auxiliary groove line therefore represents a limitation of the spliced-on area. A displacement of the individual laminate layers spanning this area is therefore not possible with the known laminate.
  • the auxiliary groove lines can be arranged parallel to the associated fold or, starting from the cabinet corners, also at an angle to it.
  • the position of the auxiliary groove lines in relation to the respective body groove lines and the central axis of the blank is also variable.
  • the auxiliary groove lines can either be arranged in each case between the fold and the central axis of the blank or in each case outside the area between the fold and the central axis of the blank. They should be right or left pointing in pairs with respect to the central cutting axis.
  • good results are obtained if the auxiliary groove lines from the cabinet corners run only up to a distance of 5 to 15 mm from the base seam line.
  • auxiliary groove lines run from the body corners to the base seam line.
  • the auxiliary groove lines can run from the carcass corners to the cut edge, but then proposed to interrupt the web seam base line in the area of the auxiliary groove lines.
  • auxiliary groove lines arranged according to the invention instead of the solid body groove lines it is achieved that in the manufacture of thick-walled packs and ultimately when they are closed, the durability of the web seam closure is retained in its original form in the filling machine. It does not matter whether the package was made directly from the cut or from the intermediate product, the jacket. Bridge seam breaks, as were customary in the prior art, are now avoided, as a result of which packs which have to be produced from relatively thick composite materials can still be used as long-term packs, since the penetration of moisture through the bridge seam breakage is avoided.
  • auxiliary groove lines are not congruent with the fold and pre-break lines, which is why the inner layer of the composite in the crease cross area is less exposed during the folding or pre-break in the folding box gluing machine, and therefore not with the flattened jacket, because the jacket is laid flat in the fold line and not in the auxiliary groove line. This prevents the inner polyethylene bad being pierced when the web seam is formed and laid flat, for example by the aluminum foil which is thrown up, as a result of which the desired tightness of the coating is maintained.
  • a method is preferably used in which the non-continuous body lines in the gable area are created and thus broken in the gable area during the formation of the sheath in the free folding and folding of the adjacent side of the pack, for which purpose the shells are moved in the direction of the longitudinal axes of the blank, whereby the bottom of each jacket is at the front in the running direction.
  • This procedure will the backing material is rolled through the free folding, ie without prior grooving during folding and refolding, so that the backing material splices and becomes soft.
  • a carrier material 2 consisting for example of a two or more layers of cardboard or foamed polystyrene on its top, which is the same as the outside of the package, with a polyethylene layer 3 is coated.
  • an aluminum foil 4 with a thin polyethylene layer 5 is laminated onto the lower layer pointing towards the inside of the pack in this exemplary embodiment.
  • a thick polyethylene film 6 is laminated on, which comes into direct contact with the contents in the finished pack.
  • the carrier material 2 can be different from the one described above Have structure.
  • the aluminum foil 4 with the corresponding polyethylene lamination 5 is dispensed with.
  • the essentially known rectangular blank 7 consists of a central part, the body 8, an upper part, the head 9 and a lower part, the bottom 10.
  • the body 8 is delimited by horizontal and vertical body groove lines 11 and 12, respectively. It is these body groove lines 11, 12 which form the front of the body 13, the back of the body 14, 114 and the side walls 15, 16 of the body.
  • the head 9 has the gable surfaces 17, 18, 118 and the surface for the triangular folding tabs 20, 21.
  • the web seam base line 23 runs parallel to the upper cutting edge 22 at a relatively small distance. This web seam base line 23 runs simultaneously through the intersection of the groove lines 24.25 delimiting the triangular folding tabs 20, 21.
  • the extensions of the vertical body edges or body groove lines 12 shown dotted in the drawing in the head 9 are not embossed in the cut, but are later folded in free folding during the production of the package or during the production of the packaging jacket 26 (see FIG. 6). These dotted lines are to be designated here with fold 27 to 30.
  • parallel auxiliary groove lines 31 to 34 are introduced into the blank. In the example shown, these parallel auxiliary groove lines 31 to 34 have been grooved into the blank in relation to the body groove lines 12 or to the folds 27 to 30 between them and an imaginary central cutting axis 35.
  • FIG. 3 shows a blank that basically corresponds to the blank in FIG. 2.
  • the only difference is that the auxiliary groove lines 36 to 39 are no longer parallel, but now run obliquely.
  • the starting point for these auxiliary groove lines 36 to 39 each starts from the intersection points of the horizontal and vertical body groove lines 11, 12, which form the upper corner points 41 to 44 of the finished pack.
  • the inclined position is inclined so that the end points of the auxiliary groove lines 36 to 39 end at a distance 40 from the fold lines 27 to 30 at the upper cutting edge 22 of the blank.
  • the auxiliary groove lines 36-39 point with their oblique position to the central cutting axis 35.
  • auxiliary groove lines 45 to 47 show further variants for the auxiliary groove lines 45 to 47, these generally starting from the same corner point 41 to 44, but are now arranged to point away from the central cutting axis 35.
  • FIG. 4 A special feature is shown in FIG. 4 in that the auxiliary groove line 45 ends at a distance 48 in front of the web seam base line 23.
  • the auxiliary groove line 47 ends at the web seam base line 23.
  • the auxiliary groove line 46 is carried out up to the cutting edge 22 and here has a distance 40 from the fold 29 .
  • the web seam base line 23 is interrupted in the area of the fold 29 and the auxiliary groove line 46.
  • FIG. 6 shows a jacket 26 which has been produced from the blanks 7 corresponding to FIG. 3 on a folder gluer or in a filler.
  • the blank 7 is guided in the direction of travel (ground ahead) according to arrow 50 through one of the aforementioned machines.
  • the individual blank parts 14, 114, 15 and 16, which form the corresponding packing sides, namely the rear side and the respective side walls, are placed one after the other from the flat position by 180 °, so that the adjacent blank parts touch each other. Then these Cut parts moved back to their original position (flat position).
  • This process is known as pre-breaking.
  • the fold line 27 extension of the vertical body groove line 12
  • the fold line 27 is created in free folding, since there is no groove in the dotted line 27.
  • a guide aid for the fold line 27 is created to a certain extent only by the only adjacent auxiliary groove line 36, so that the fold line 27 can move in a predetermined direction.
  • the cardboard 2 is spliced in the area of the head 9 (see FIG. 10), so that the material composite 1 becomes elastic and flexible and no longer breaks when the triangular folding flap 20, 21 is subsequently folded over (see FIG. 14). .
  • the edges of the later longitudinal seam 51 are activated, whereupon the rear sides are then activated 14, 114 are moved towards each other again and joined together.
  • FIG. 7 shows the perspective illustration of how the parallel auxiliary groove lines 31 to 34 run with respect to the horizontal body groove lines 11 and the fold lines 27 to 30.
  • the triangular folding flaps 20, 21 and the web seam 52 have not yet been folded over. This only happened in FIGS. 8 and 9 and is shown accordingly. The only difference between these two representations is that the web seam 52 in Figure 8 has been moved to the left and Figure 9 to the right.
  • FIG. 10 shows a cross section of a casing 26 from FIG. 6 which is formed at a right angle.
  • the spliced areas 54 in the cardboard layer 2 can be clearly seen.
  • the position of the individual auxiliary groove lines, for example 36 to 39, can also be seen. The same applies to the auxiliary groove lines 31 to 34.
  • Fig. 11 it is shown how, in the prior art in the area of the double-lying triangular folding flaps 20, 21 and the web seam 52 covering them, not only all the groove lines of the individual layers lie congruently one above the other, but also in alignment with the side wall, so that when these layers are turned over - as shown in FIG. 12 - the tension in the outer layer becomes so high that it breaks.
  • the groove lines are initially distributed so that they are neither congruent one above the other nor in alignment with the side wall, and beyond a splicing of the material composites or layers to be shifted has been achieved by the milling process when pre-crushing, so that now due to the possible larger folding radii 55 and thinner composites in Fold the stresses over all composite layers, which prevents the outer layers from breaking.
  • FIG. 15 in a section of a blank, using the example of the auxiliary groove lines of FIG. 5, a further exemplary embodiment is shown, in which the web seam base line 23 is interrupted in the region of the auxiliary groove line 46 or 47, the distance 56 of the interruption being of the order of, for example is about 6 to 10 mm.
