Definitions
- the invention relates to an essentially gas-tight package for packaging 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 packaging materials forming the doubling area -Layers are connected to each other on the inside of their packaging material by means of a strip-shaped sealing area, the packaging sleeve being intended 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. 0152291) 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 area of a chocolate bar dividing notch and that runs along one within the strip-shaped area in which the two fold flanks are connected to one another by a seal Line of weakness several from each other has separate linear punchings.
- the invention is first of all the object of specifying a pack of the type mentioned at the outset, which can be opened in a simple manner in such a way that the original form of the pack is not substantially changed when the packaged goods are opened and removed: and also for relatively soft packaging goods can be used.
- the pack according to the invention which is characterized in that, in the case of a pack having an at least flat surface area, the packing envelope on this surface area — arranged at a distance from one another — has two strip-shaped doublings areas in which the two layers of packaging material forming the doubling area are connected to one another on their inside of the packaging material via a strip-shaped sealing area, which, however, according to the invention now enclose a tear-open area of the packaging envelope laterally.
- These two folds can advantageously be arranged in the vicinity of two mutually opposite edges of the flat surface area of the pack.
- the tear-open area is laterally delimited by outer edges of the double areas surrounding the tear-open area.
- the package according to the invention is characterized in that the tear-open area is laterally delimited by line-shaped predetermined breaking points in the packaging material, each of which is arranged in the outer layers of the double areas enclosing the tear-open area and in each case within their strip-shaped sealing areas.
- the pack according to the invention is characterized in that the doubling areas are each folded over in the direction away from the tear-open area on the pack surface.
- the layers of packaging material lying on the packaging surface of the folded double regions are advantageously connected to the packaging surface at least over part of their surfaces by gluing or welding.
- the package according to the invention is characterized in that the package is a tubular bag package with a longitudinal sealing seam and two transverse sealing seams forming the fins of the package, the two doubling regions bordering the tear area laterally parallel to the longitudinal sealing seam and the sealing area of at least one of the transverse sealing seams cross, and the tear area being delimited by the free edge of at least one of the fins.
- the sealing area of the transverse sealing seam does not reach the free fin edge, at least in the area between the ends of the two doubling areas.
- this is characterized in that the doubling areas, at which linear break points in the packaging material form lateral boundaries of the tear-open area, are packaging material folds formed on the packaging surface.
- the invention further relates to two advantageous methods for producing the pack according to the invention.
- a first method of this type is characterized in that two folds are formed at a distance from one another in the packaging material, the flanks of which are each connected to one another by sealing in a strip-shaped sealing region, in that a strip-shaped region of the fold extending in the longitudinal direction of the fold is cut off at the fold edges, so the remaining material of the folds double Formation areas of the packaging material, the packaging material layers have outer edges that laterally limit a tear-open area of the packaging material in the pack to be produced, that the two doubling areas are then folded over onto the packaging surface and that the packaging envelope is then produced from the packaging material thus prepared.
- a second method according to the invention is characterized in that two linear predetermined breaking points spaced apart from one another are provided in the packaging material, that a fold is formed in the packaging material at each of these predetermined breaking points, the flanks of which are connected to one another by sealing in a strip-shaped sealing area, so that the predetermined breaking points each come to rest on one of the flanks of the folds within the strip-shaped sealing area, that the two folds are folded over onto the packaging envelope and that the packaging envelope is then produced from the packaging material thus prepared.
- 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 package before the packaging material tube is formed.
- a packaging material web 1 which is provided on one side with a sealing layer attached in the profile and with two lines of weakness which run in the longitudinal direction of the web, that is to say in FIGS. 1 and 2 perpendicular to the plane of the drawing, and serve as predetermined breaking points for the pack to be produced, is pulled off the roll in the packaging machine and two folds 2 and 3 are then continuously formed on it, the two flanks of each fold 2, 3 being connected to one another over the entire width of the fold by sealing the profile sealing layers present at these points.
- 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 level of the packaging material web 1 in such a way that the fold sides which contain the weakening lines 4 do not lie against the surface of the packaging (see FIG. 2).
- the packaging material web 1 thus provided with the two folds 2, 3 in its longitudinal direction (ie, perpendicular to the plane of the drawing in FIG. 2) is now moved in the usual way to form a packaging material tube around the successively supplied packaging items, for example chocolate bars 5, in the direction of Arrows 6 are turned 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 over onto the tube surface.
- the packaging material tube enclosing the chocolate bars 5 is now each Weil between two consecutive chocolate bars with two parallel sealing seams running parallel to each other and divided into individual packs 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 region 13 with a width of approximately 3 up to 8 mm, in which the packaging material hose 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 lying 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 gripped at its free edge 17 with the other hand and pulled in the direction of arrow 20.
- the edges of the tear area 18 of the other parts of the case are on the two folds 2, 3 with simultaneous tearing of the packaging material on the weakening lines 4 ten 2, 3 peeled off with the seal fixing these folds.
- 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 which, starting from the outside of the pack, consists of a 0.012 to 0.015 mm thick film made of biaxially stretched polypropylene (OPP), a 0.008 to 0.009 mm thick aluminum film provided on the outside with a decorative imprint, a paper with a grammage of 40 to 50 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. However, these line-shaped punchings can also be applied to the packaging machine immediately before the folds 2, 3 are formed in the packaging material web with the aid of a suitable device when producing the packaging material web.
- a packaging material web 22 which is provided on one side with a sealing layer applied in the profile, but which in contrast to the packaging variant according to FIGS. 1 to 4 now has no lines of weakness, is pulled off the roll and in it, Analogously to that described with reference to FIGS. 1 and 2, two folds 23 and 24 are continuously formed (see FIG. 5). Subsequently, a strip-shaped region 25 of the folds 23 and 24, which in FIG. 5 runs perpendicular to the plane of the drawing and 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 perspective partial view.
- 7 also shows the two doubling regions 23 'and 24' which have been folded over onto the packaging surface. To open the package, the packaging material lying at the bottom in FIG.
- 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. 3g / m 2 solid).
- the doubling regions 23 ', 24' which are folded over onto the packing surface can be connected to the packing surface by gluing or welding.
- hot glue is applied to them at the intended bonding points 27 (see FIG. 5), after which the doubling areas are folded over and pressed briefly onto the packaging material web 22, whereby the bonding is complete.
- the packaging material is already on the outside of the packaging material rials at points 27 and 28 each applied strip-shaped coatings from a heat-sealing lacquer, for example one based on PVC / PVAc copolymer (application thickness 1 to 3 g / m 2 ).
- a heat-sealing lacquer for example one based on PVC / PVAc copolymer (application thickness 1 to 3 g / m 2 ).
- the packaging machine after the doubling areas 23 ', 24' have been folded over, they are connected to the packaging material web 22 by heat sealing.
- the substantially gas-tight and easy-to-open package according to the invention can, preferably in the form of a tubular bag package, advantageously be used for packaging chocolate, waffles or other products in the form of bars.
