Definitions

  • the invention relates to a film-like material for a folding pack and a corresponding folding pack, in which the film-like material is folded and closed around a product to be packaged in such a way that the product is airtightly surrounded by it on all sides.
  • the film-like material or the folding pack has a single film web, the opposite edge regions of which frame the inner region of the film web laterally are each provided with an adhesive layer.
  • Folded packs produced accordingly serve for the packaging of, for example, freeze-dried coffee, biscuits, so-called sweet bars or other stimulants which are to be packaged in an airtight and moisture-proof or aroma-tight manner.
  • the film web itself usually consists of a composite material or aluminum.
  • the invention has for its object, while avoiding these disadvantages known from the prior art to provide a folding pack and the material used, which allow such folding packs in an economically simple manner, even without the aid of cutting tools, without problems and gentle on the packaged goods Way to open.
  • This invention is given for the film-like material provided for a folding pack by the features of claim 1 and for the correspondingly produced folding pack by the features of claim 6.
  • the folding pack according to the invention thus consists of a single film web.
  • the opposite edge areas of this film web, which laterally frame the inner area thereof, are each provided with an adhesive layer.
  • the inner area itself, which directly envelops the goods to be packaged, is not provided with an adhesive layer.
  • This film web according to the invention is characterized in that the opposite two edge regions each have at least one non-permanently adhesive region, these regions of the two edge regions lying one above the other in the state folded into a folded pack: Furthermore, the film web is along the circumferential line of one of these two edge regions from the rest The edge area is partially separated in terms of material, the adhesive layers being present between these non-permanently adhesive two areas and the respective adjacent inner area, so that the inner area is completely framed on the side by the adhesive layers. As in the prior art, the goods to be packaged are framed on all sides by an adhesive layer, so that tight packaging is made possible.
  • this tab is possible in a variety of ways.
  • the tab can thus be present completely within one of the two edge regions lying one above the other, which means that its circumferential line is completely present within the corresponding edge region.
  • the tab can also be produced by one, in particular two, spaced-apart edge incisions.
  • the tab tears open the intermediate area between it and the inner area.
  • This intermediate area is provided with an adhesive layer in the closed state of the pack, since the goods to be packaged must be closed on all sides.
  • a folding pack 10 according to the invention has an envelope which is formed from a single film web 12. This film web 12 is shown in sections in the longitudinal direction L and unfolded in FIG. 3. The bending edges 15, 17, 19 and 21 formed on the pack 10 between the upper side 14, rear side 16, lower side 18 and the lower region 20 or upper region 22 of the front side are shown in broken lines in FIG. 3.
  • a so-called longitudinal seam fin 24 is present on the folding pack 10 and is formed by the two outer longitudinal edge regions 26 and 28, respectively. These longitudinal edge regions 26, 28 are glued to one another in the folded state to form the pack 10. Along the bending edge 30 present between the longitudinal seam fin 24 and the lower or upper region 20, 22 of the front side, the longitudinal seam fin 24 is present, folded over - in FIG. 1 downwards. This longitudinal seam fin 24 also extends around the two end faces 32 of the pack 10 and is fastened there to the end seam fins 34 which are present there in each case.
  • the film web 12 is in its longitudinal edge regions 26 and 28, d. H. Provide an adhesive layer 40 or 42 in their edge regions adjoining the bending edge 30 in cross-section to the outside.
  • the area between the two bending edges 30 (FIG. 3) which extend in the longitudinal direction L forms the inner area which lies directly against the goods to be packaged and which is therefore not provided with an adhesive layer.
  • Fig. 3 the film web 12 is shown with its outside as it is visible on the package 10.
  • the adhesive layers 40, 42 are then on the underside and would not be visible according to the illustration in FIG. 3.
  • the partial area 50 is framed towards the outer edge 52 by an approximately semicircular outline 54, along which the film web 12 is cut open.
  • This outline 54 thus represents a cutting or punching line.
  • the partial area 50 thus forms a flap which is created by bending this partial area 50 out of the plane of the remaining film web 12.
  • the bending line 55 formed when this partial area is opened runs approximately parallel to the bending edge 30.
  • the adhesive layer 40 is also present in the intermediate area 56 between the bending line 55 and the bending edge 30.
  • the adhesive layer 40 is aligned with its longitudinal structure 41 so that the longitudinal structure is parallel to the tear-open direction of the package 10, i. H. runs parallel to arrows 58. This can be achieved by appropriate application direction of the adhesive layer 40 on the film web.
  • the partial area 50 can easily be torn open in the direction 58 over the intermediate area 56 and thus the package 10 can be opened.
  • the partial area 60 of the other longitudinal edge area 28 on the package 10 below the partial area 50 is likewise not provided with an adhesive layer, while the remaining longitudinal edge area 28 around the partial area 60 is provided with the adhesive layer 42.
  • This adhesive layer 42 is also present in the illustration according to FIG. 3 on the underside of the film web 12.
  • FIG. 1 In the lower part of the longitudinal edge areas 26, 28 of FIG. 3, another type of design for a flap design is shown, which is not shown in FIG. 1.
  • the partial area 50 is not formed by a semicircular outline 54 but by two spaced-apart cutting lines 70 in the longitudinal edge area 26, which partially protrude from the outer edge 52 into the longitudinal edge area 26 provided with adhesive layer 40.
  • the partial area 72 between these cutting lines 70 corresponds in effect to the partial area 50.
  • a partial area 74 which corresponds in effect to the partial area 60, is also recessed from the adhesive layer 42.
  • This partial area 74 is at least as large as the partial area 72, so that the partial area 72 in its function as a tab can be moved away from the partial area 74 and the package 10 can be torn open accordingly.
  • the on The tearing movement is again parallel to the arrows 58.
  • the above-mentioned adhesive layers 40, 42 represent only one possibility of simply firmly connecting the two longitudinal edge regions 26, 28 to one another. Instead of the two adhesive layers 40, 42, only a single adhesive layer 40 or 42 could also be present. In addition, it would also be possible to establish the fixed connection by, for example, heat sealing. It remains important that a partial area of a longitudinal edge area 26 or 28 is not firmly connected to the corresponding other longitudinal edge area 28 or 26 and is separated by a dividing line from the remaining longitudinal edge area, so that a flap is formed on a seam fin of a pack can be.
