Definitions

  • the invention relates to a packaging, in particular for confectionery such as chocolate bars etc., according to the preamble of claim 1, a blank for forming the packaging according to the preamble of claim 6 and a method for producing the packaging according to the preamble of claim 14.
  • Packaging of the type mentioned here is known from a blank which forms an outer wrapper and is folded around the (solid) object to be packed, for example a chocolate bar.
  • the packaging has an inner wrap made of aluminum foil.
  • the bil the outer wrapping The blank is enveloped around the chocolate bar and the inner wrapping made of aluminum foil.
  • a closure flap of the outer covering formed from the blank is glued to an underlying flap by means of an overlap seam.
  • cold adhesives are suitable for bonding a wide variety of packaging materials, in particular also for single or multi-layer plastic films.
  • cold glue can already be applied to the still flat blank in a simple manner, for example by printing, so it does not need to be applied to the packaging, which is largely folded around the chocolate bar, just before the seam is closed, just before the seam is closed.
  • a problem with the use of cold glue for the production of overlap seams is the necessity of applying cold glue on both sides to the seam halves opposite to form the overlap seam. This requires both application of the cold glue on both sides of the blank, as well as measures to prevent the overlapping of blanks or the individual turns of a rolled-up material web.
  • the object of the invention is to create a packaging and a blank and a method for producing the same, the disadvantages mentioned above being eliminated when using cold adhesives to form overlap seams.
  • a packaging for solving this problem has the features of claim 1.
  • the adhesive sections are brought to cover at least in the area of the overlap seam despite their only one-sided application to the blank. It is therefore possible to produce overlap seams from the blank, which is only coated on one side, using cold glue.
  • a (narrow) edge region of the blank provided with a continuous or several interrupted adhesive sections is expediently folded over inwards.
  • one or more adhesive sections in the region of the edge area reach a side of the blank that is directed away from the other adhesive sections, which results in a blank that is coated on almost two sides to form the closure seam.
  • the edge region to be folded over is preferably an outer, transverse edge strip of the closure flap. After the edge area has been folded over, the fold line forms a new outer edge of the closure flap.
  • the width of the adhesive section located on the edge area is narrower than the actual bent-over edge area, as a result of which the outside of the finished packaging, in particular the overlap seam, is free of glue points, i.e. they are no longer visible on the outside of the packaging are.
  • a blank used to solve the task has the features of claim 6.
  • the adhesive sections preferably running all around on one side of the blank in the areas of the edges thereof, it is possible to form an almost tight packaging from the blank.
  • Such a blank is particularly suitable for a single-layer packaging in which, due to the high tightness of the blank folded around the chocolate bar or the like, the inner wrap made of a tinfoil that is customary in the case of previously common chocolate packaging film can be omitted.
  • the tinfoil film has the task of sealing the chocolate with aroma-tight sealing and protecting it from foreign objects penetrating from the outside.
  • the desired tightness is achieved by connecting all the adhesive sections arranged on one side of the blank. These are expediently connected to one another by (narrower) residual adhesive connections which have a smaller width than the adjacent adhesive sections. This minimizes the need for cold glue, since there are correspondingly large adhesive sections where individual areas of the folded blank are to be held together and, in contrast, in the other areas, where only the necessary tightness of the packaging is to be achieved, there are the narrower remaining adhesive sections.
  • the (narrower) residual adhesive sections are arranged in the region of fold lines of the blank. This ensures that the cold glue does not impair the correct folding of the blank by the fact that, due to the narrow remaining adhesive sections, exact folding edges can be formed, which roughly correspond to those of conventional packaging.
  • a method for solving the problem has the features of claim 14.
  • the edge region of the blank provided with at least one adhesive in the cut is folded over after being pulled off a continuous (rolled-up) material web, preferably during the cutting of individual blanks from the material web or immediately after the blank has been separated therefrom .
  • no additional work cycle is required for folding over the edge area, while on the other hand, folding over the edge area and the associated formation of adhesive spots from cold adhesives on an opposite side of the blank during further processing of the same can no longer lead to any impairments, in particular unwanted adhesive bonds.
  • the edge strips on the closure flap are only folded over when opposite side edges thereof have been provided with closure side flaps.
  • the folded-over edge areas of the blank do not interfere with the other folding processes, that is to say, a packaging is created that corresponds to the chocolate packaging described at the beginning.
  • the packaging shown here is used to hold a chocolate bar 10.
  • the packaging is made in one piece, namely consists of a single blank 11 (FIGS. 1 and 2).
  • the packaging (soft packaging) formed from the blank 11 has a rectangular top wall 12, four adjoining (narrow) side walls, namely two long side walls 13 and two short side walls 14, and a bottom wall 15.
  • the bottom wall 15 is formed from one with a long side wall 13 connected flap 16 and a (outer) closure flap 18 partially covering them in the area of an overlap seam 17 (FIG. 1).
  • the blank 11 for forming the packaging has, in addition to the above-mentioned tabs and walls, side tabs 19 extending the short side walls 14 and narrow side tabs 20 extending the closing tab 18.
  • corner flaps 21 and 22 are arranged between the closure side flaps 20 and the side flaps 19 on the one hand and the flap 16 and the side flaps 19 on the other hand.
  • a free transverse edge 23 of the closure flap 18 is extended by a (narrow) edge area 24. This extends continuously over the entire width of the blank 11 (FIG. 3).
  • the individual areas of the blank 11 are separated from one another by folding lines 25, 26 which arise when the latter is folded around the chocolate bar 10. These are indicated by dashed lines (FIGS. 3 to 5).
  • the blank 11 is provided on only one side with a plurality of adhesive sections 27, 28. These are grouped at a distance from one another around the edges of the blank 11, with free spaces 30 between adjacent adhesive sections 27 and 28, respectively, in the regions of the fold lines 25, 26 which are indicated (FIG. 3).
  • the arrangement and formation of the adhesive section 28 on the edge region 24 is special in accordance with the invention on the one hand and the adhesive section 29 in the region of the free edge 31 of the tab 16.
  • These adhesive sections 28, 29 are used to form the overlap seam 17, in that after the blank 11 with the external adhesive sections 27, 28 and 29 has been folded around the chocolate bar 10 and the edge region 24 has been folded over with the adhesive section 28 against the uncoated inner side of the blank 11 sealed packaging, namely on the flap 16 from the outside of the sealing flap 18, the adhesive sections 28 and 29 lie together with an overlap for securely closing the packaging (FIGS. 1 and 2).
  • the blanks 11 are formed from a continuous (rolled-up) material web, then this can already be provided with the ready-printed adhesive sections 27 ... 29, since, because of the one-sided printing of the material web with the adhesive sections 27 ... 29, individual turns of the Material web is not to be feared.
  • the blanks 11 can be continuously formed from this material web by appropriately severing them. With this severing, the edge region 24 of the blank 11 can be folded over at the same time when the severing cut coincides with the transverse edge 43 of the edge region 24. If the transverse edge 43 of the edge region 24 is directed transversely to the dividing line, that is to say runs along the direction in which the material web is pulled from the supply roll, the edge region 24 is advantageously folded over after the blank 11 has been separated from the material web.
  • the blank 11 separated from the material web has a quasi-two-sided coating and its final dimensions, in which the excess for the edge region 24 has been turned inwards and the fold line 32 forms the free transverse edge 23 of the closure flap 18.
  • the blank can then be cut around the chocolate bar 10 - which, in deviation from the exemplary embodiment shown, has also previously been provided with a conventional tinfoil can - fold around by first covering the top wall 12 of the blank 11 with a (profiled) surface of the chocolate bar 10 and then successively folding over the sections of the blank 11 adjoining the top wall 12 to form the indications just shown in the blanks just shown ( 3 to 5) shown folding lines 25, 26, wherein on the outer adhesive sections 29 on the flap 16 when the closure flap 18 is closed, the inwardly folded adhesive section 28 of the edge region 24 comes to lie to form the overlap seam 17 coated on both sides with cold glue.
  • the shorter and narrower design of the adhesive section 28 on the edge area 24 ensures that no cold adhesive is exposed when the packaging is finished, that is to say it is visible from the outside.
  • the remaining adhesive sections 27, 29 are arranged at a distance from the outer edges of the blank 11.
  • the blanks 11 for forming the packaging according to the invention can also come from a blank stack. Due to the one-sided arrangement of the adhesive sections 27..29, the blanks 11 lie on one another without their adhesive sections 27... 29. As a result, the blanks 11 can be removed from the bar and processed further without the risk of sticking together.
  • edge region 24 is folded over when the blanks 11 are individually removed from the stack before the latter is folded around the chocolate bar 10.
  • opposite edge regions namely the closure side tabs 20
  • the closure flap 18 is closed the inner adhesive portion 28 folded against the outer adhesive portion 29 on the tab 16 (Fig. 1 and 2).
  • an adhesive section 28 can be expedient, which extends across the width of the closure flap 18 into the area opposite lying closure side flaps 20, whereby after the closure side flaps 20 have been folded against the closure flap 18, lateral edge regions of the adhesive section 28 overlap to hold the retracted closure side flaps 20 on the inside of the closure flap 18 until the latter is folded against the flap 16 to form the overlap seam 17.
  • FIG. 4 a comparable packaging can be formed with a blank 33 (FIG. 4) developed according to the invention.
  • This also has a rectangular base with the same sections and the same folding lines 25, 26 as are present in the blank 11 described above. In this respect, reference is made to this.
  • the cut 33 differs from the cut 11 essentially in the design of the adhesive sections 34, 35 and 36, which are likewise applied on one side. These are in turn arranged in the edge regions of the cut 33, in a directly connected manner.
  • the adhesive sections 34... 36 thus form a circumferential cold adhesive surface in the case of the blank 33, from which particularly tightly sealed packagings can be produced, and thus an inner wrap made of aluminum foil, which is otherwise common, is no longer necessary.
  • the adhesive section 36 on the flap 16 and the adhesive section 35 on the edge region 24 on the closure flap 18 serve to form the overlap seam 17 with at least partially overlapping adhesive layers 35, 36 (analogous to FIG. 2).
  • the blank 37 (FIG. 5) is further developed according to the invention compared to the blank 33 (FIG. 4) described above in such a way that the adhesive sections 38, 39, 40 are connected to one another by (narrow) residual adhesive sections 41, that is to say also over the entire edge of the To section 37 run continuously.
  • the remaining adhesive sections 41 which are narrower than the adhesive sections 38, 39 and 40, lie in the area of the fold lines 25, 26. This ensures on the one hand that the residual adhesive sections 41 result in an almost tight packing, but on the other hand the residual adhesive sections 41 due to their compared to the other adhesive sections 38 ... 40 narrower training in the formation of fold lines 25, 26 do not interfere appreciably.
  • Various materials can be used to form the blanks 11, 33, 37, for example paper waxed on one or two sides, a plastic film or else composite films made of the same or different materials (plastic / paper, aluminum-vapor-coated plastic, etc.).
  • the blanks 11, 33, 37 can also be used with appropriately adapted dimensions to form packaging for other objects.
