Definitions

  • the invention relates to an essentially gas-tight package with lumpy packaging goods, in particular divided or subdividable into several parts, with a casing formed from a flat, foldable packaging material, which has at least two strip-shaped doubling areas of the packaging material, in each of which the two layers of packaging material forming the doubling area the inside of their packaging material is connected to one another via a strip-shaped sealing area, the packaging sleeve being designed to be opened at least in one of these doubling areas in order to open it.
  • the packs according to the invention are preferably not designed exclusively as tubular bag packs.
  • the invention further relates to advantageous methods for producing the pack according to the invention.
  • a pack of this type is described in European patent application 85104700.1 (publication no. 0162291) with reference to FIG. 3.
  • This package which is a tubular bag package for packaging chocolate, has a fold that starts from the packaging envelope in the region of a chocolate bar division notch and that runs along one within the strip-shaped region in which the two fold flanks are connected to one another by a seal Line of weakness has a plurality of separate line-shaped punchings.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, solves the problem of displaying a package of the type mentioned, but which can now be opened in such a simple manner that the original shape of the package is not significantly changed when packaging is removed and which can also be used for relatively soft packaging goods.
  • the invention further relates to two advantageous methods for producing the pack according to the invention.
  • Figures 1 and 2 each illustrate in sectional views the manufacture of a preferred embodiment of the package according to the invention in the form of a tubular bag pack before forming the packaging material hose.
  • the folds 2, 3 are attached in such a way that the two mentioned weakening lines 4 (running perpendicular to the plane of the drawing in FIG. 1) come to rest on the inner flank flank (see FIG. 1).
  • the folds 2, 3 are then folded over onto the plane of the packaging material web 1 in such a way that the fold flanks which contain the weakening lines 4 do not lie against the packaging surface (see FIG. 2).
  • the packaging material web 1 thus provided with the two folds 2, 3 in its longitudinal direction (i.e. perpendicular to the plane of the drawing in FIG. 2) is now used in the usual way to form a packaging material tube around the successively supplied packaging items, e.g. Chocolate bars 5, folded over in the direction of arrows 6 around the packaged goods, after which the edge regions of the packaging material web on the underside 7 of the chocolate bars 5 are connected to form a longitudinal sealing seam and the fin formed by this longitudinal sealing seam is then folded onto the surface of the tube.
  • the packaging material tube enclosing the chocolate bars 5 is now provided with two transverse sealing seams running parallel to each other between two successive chocolate bars and divided into individual packages by separating cuts between these two transverse sealing seams.
  • FIG. 3 shows the longitudinal sealing seam 8 folded over on the packaging surface and the fin 10 produced by a transverse sealing seam 9. Between the free edge 11 of this fin 10 and the strip-shaped sealing region 12 of the transverse sealing seam 9 there is a strip-shaped area 13 with a width of about 3 to 8 mm, in which the packaging material tube is only compressed. From Fig. 3 can also be seen the two folds 2, 3 folded over on the pack surface, the outer fold edges of which each end with the two side edges 14, 15 of the pack. The two weakening lines 4 and the free edge 17 between the ends 16 of these weakening lines of the packaging material layer of the fin 10 located at the top in FIG. 4 thus delimit a tear-open area 18 of the packaging envelope on three sides.
  • the packaging material layer of the fin 10 at the bottom in FIG. 3 is held at 19 with one hand and the upper packaging material layer containing the tear-open area 18 is grasped at its free edge 17 with the other hand and pulled in the direction of the arrow 20.
  • the edges of the tear-open area 18 are peeled off from the remaining parts of the folds 2, 3 on the two folds 2, 3 while the packaging material is torn at the weakening lines 4, with the seal fixing these folds being separated.
  • Fig. 4 shows the pack in an analog representation as in Fig. 3; but now in a half-open condition.
  • a three-layer packaging material is used - starting from the outside of the package - made of 0.012 to 0.015 mm thick film made of biaxially stretched polypropylene (OPP), a 0.008 to 0.009 mm thick aluminum film with a decorative print on the outside , a paper with a grammage of 40 to 60 g / m 2 and a latex-based cold adhesive coating preferably applied in the profile (for example approx. 3 g / m 2 solid).
  • the weakening lines each consist of a plurality of line-shaped punchings arranged one after the other in the course of the weakening line and separated from one another. These line-shaped punchings can, however, also be attached to the packaging machine immediately before the folds 2, 3 are formed in the packaging material web with the aid of a suitable device in the manufacture of the packaging material web.
  • a packaging material web 22 is provided in the packaging machine, which is provided on one side with a sealing layer applied in the profile, but which, in contrast to the pack variant according to the figures 1 to 4 has no lines of weakness, is pulled off the roll and, in the same way as described with reference to FIGS. 1 and 2, two folds 23 and 24 are continuously formed in it (see FIG. 5). Subsequently, a fold length extension is made at the fold edges, i.e. in Fig. 5 perpendicular to the plane of the strip-shaped area 25 of the fold 23 or 24, which is shown in Fig.
  • the packaging material web 22 thus provided with doubling regions 23 'and 24' is now used, analogously to that described with reference to FIG. 2, to produce a tubular bag pack for chocolate bars 5.
  • FIG. 7 shows the tubular bag package thus produced in a partial perspective view.
  • 7 also shows the two doubling regions 23 'and 24' which have been folded over onto the packaging surface.
  • the packaging material layer of the fin 10 'at the bottom in FIG. 7 is held at 19' with one hand and the upper packaging material layer containing the tear-open area 26 is grasped at its free edge 17 'with the other hand and in the direction of the arrow Deducted 20 '.
  • the sealing connections of the two doubling areas 23 'and 24' are peeled off.
  • this pack is in an analog representation as in Fig. 7; but now in a half-open state, i.e. in which a part of the tear-open area 26 has already been drawn off.
  • a very simple packaging material is used, which, starting from the outside of the pack, consists of a decorative print, a metallization, a 0.02 to 0.04 mm thick OPP film and a latex-based calf adhesive coating (e.g. 3 g / m 2 Solid).
  • the doubling regions 23 ′, 24 ′ which have been folded over onto the packaging surface can be connected to the packaging surface by gluing or welding.
