Definitions

  • the invention relates to a film web for a folding package made of film-like material, in which the film web having a certain width is folded around a product to be packaged and closed in such a way that it surrounds the product airtight on all sides.
  • the invention further relates to the folding pack made from such a film-like material and to a method for producing this film web.
  • Flowpack Such packaging is known under the name "Flowpack”.
  • This packaging is used for packaging, for example, freeze-dried coffee, biscuits or other stimulants, which should be packed airtight and moisture-tight or aroma-tight.
  • the invention is based on the object, while avoiding these disadvantages known from the prior art, of specifying a folding pack and a method for producing the same, which allow such folding packs to be opened easily and in a gently manner on the packaged goods even without the use of cutting tools.
  • This invention is given in a film web by the features of claim 1, in a folding pack by the features of claim 8 and in the method for producing the film web for such folding packs by the features of claim 11.
  • the inventive film web of the type mentioned above is accordingly characterized in that the film web is composed of at least two web parts, these web parts being aligned parallel to one another and overlapping with their respective one longitudinal edge regions. These web parts are also connected to one another in the overlapped area.
  • the method according to the invention for producing the film web in which the film web is fed around deflection rollers all the way to a packaging station that contains folding and connecting seam manufacturing devices, is characterized in that the at least two web parts are unwound from the correspondingly available at least two rolls that they partially overlap with their one unwound longitudinal areas, and that these overlapping areas subsequently by a longitudinal seam are connected to one another and then the web parts thus connected are fed as a film web to the packaging station with its folding and connecting seam manufacturing devices.
  • These folding packs have the advantage that they are easy to open, since only the overlapped longitudinal edge areas in the transverse direction have to be detached from one another again in order to open them. This can be easily accomplished without special aids.
  • the film web to be used is only slightly more expensive to manufacture.
  • the additional consumption of material in relation to the total costs of the packaging is negligible.
  • first film 12 and second film 14 which are each wound on a roll 16 or 18, are deflected via deflection rollers 20, 22 and 24, 26 so that they are with overlap a common area C in the withdrawal direction 30.
  • the free edge 32 of the film 12 runs parallel to the free edge 34 of the film 14.
  • the two foils 12, 14 are connected to one another in the overlapped area C by means of a longitudinal seam 38 by means of a seam-sealing station 36.
  • the edge 32 of the film 12 can thus be folded up in the upper region of FIG. 1 up to the seam 38, while in this region the edge 34 of the film 14 can be folded down down to the seam 38.
  • the width of this film web 40 is composed of the individual widths A of film 12 and B of film 14, minus the overlapped area C.
  • This film web 40 is fed to a station 50.
  • the goods 52 to be packaged are also fed to this station 50 in such a way that the film web 40 can be folded around the goods 52 - forming longitudinal folding edges.
  • the free edges 56, 58 of the film web 40 are then heated by suitable heating devices 60 and then sealed at 62.
  • This sealing creates the longitudinal seam fin known from flowpack folding packs.
  • This longitudinal seam fin is then placed at 64 on the surface of the folding pack so that it does not protrude in a disruptive manner.
  • a transverse sealing seam is applied by means of suitable sealing pliers, in front of and behind the packaged goods, so that a folded package is closed on all sides.
  • cutouts 70, 72 along the edges 32, 34. These sections are only shown in a partial area in FIG. 1; they are already advantageous in production engineering considerations prior to producing the seam 38 in the film 12 or film 14 act.
  • the cutouts 70, 72 can thus be punched out, cut out or removed in a similar manner from the edge area, for example in the draw-off area between the roll 16 and the roll 22 or the roll 18 and roll 26 in the corresponding edges 32, 34.
  • the sections have a mutual distance a and d in FIG. 1.
  • the distance a corresponds approximately to the length of a folding pack 10 (FIG. 2), while the distance d is influenced by the mutual distance of the transverse seams made by the sealing pliers at 66.
  • the cutouts 70, 72 serve to easily open a folding pack, as will be described in more detail below.
  • the folding pack 10 in particular does not differ from its underside (FIG. 3) from the flow pack pack known from the prior art.
  • the film web 40 is present on all sides around the packaged material present inside, the film web 40 being closed in the area of the stations 50, 60, 62, 64, 66 to form the longitudinal seam fin 76 and the front transverse seams 78, 80.
  • the overlapped area C of the film web 40 connected by a longitudinal seam 38 can be seen.
  • the upper free edge 32 is pulled upwards in the direction of arrow 81.
  • the cutouts 72 provided in the edge 32 make it easier to pull up.
  • the film web 40 thus tears along a transverse tear seam 82, 84.
  • the edge 34 is then pulled upward in the direction of arrow 83 (FIG. 4).
  • This edge 32 can also be pulled up very easily in the transverse direction by the existing cutouts 70, with the formation of corresponding transverse tear seams.
  • the respective remainders of the seam 38 can be seen on the underside of the film web 40 visible in FIG. 4 below the edge 32 and on the upper side below the edge 34.
  • the interior 86 is the fold pack 10 freely accessible.
  • folding pack 10.1 which differs from the folding pack 10 only in that there are webs 88 in its interior for receiving chocolates 90.
  • This folding pack 10.1 is present in the bottom part 92 of a box of chocolates.
  • the folding areas 94 of the film web 40 present in the area of the transverse sealing seams 78, 80 are completely nestled against the packaged goods, so that the folding pack 10.1 completely fills the bottom part 92.
  • the lid part 96 which is common in chocolate boxes, can be slipped over the bottom part 92 and thus also over the folding pack 10.1. After removing the cover part 96 and pulling up the edges 32, 34 of the folding pack 10.1, the aroma-fresh chocolate pieces 90 can be removed without any problems.
