Description

The invention relates to a pack for a cigarette group having the features of the preamble of claim 1.

Packings for cigarettes are usually designed so that a support member or an inner collar is disposed within a dense foil envelope having sealing block, which causes increased dimensional stability of the sealing block and protects the cigarettes against mechanical and thermal stress. The cigarette block, which is closed on all sides, is accommodated in an outer pack preferably designed as a hard pack - folding box.

The DE 10 2011 119 344 A1 shows and describes such a packing for cigarettes with an approximately tray-shaped inner collar, which has a substantially over the full height of the cigarettes extending inner front wall, an inner bottom wall and on the narrow sides of the cigarette block extending inner side walls. The back of the cigarette group is free in this embodiment of the inner collar, except for a freely movable tab, which is referred to as approach and can develop any support function for the cigarette.

Other different versions of inner collar arise from the WO 2009/098297 A1 , each in an embodiment with side walls or side lobes to protect the cigarette group in the region of these narrow, upright side surfaces of the cigarette group.

The DE 10 2010 019 867 A1 shows gaskets made according to the "flowpack" principle. Inner collar in various designs are formed in this prior art as a sleeve, at least without coverage in the region of a bottom surface on the one hand and an end face on the other.
The invention has the object of providing a cigarette packet of the aforementioned embodiment with respect to the inner support member or the inner collar in such a way that a better protection and in particular a more stable structure of the inner collar is given.
To solve this problem, the package according to the invention with the features of claim 1 is formed.
An increased or sufficient dimensional stability of the inner collar with the cigarette group surrounded by this is thus achieved when the inner collar has a closed structure at least in a lower, bottom-side region. The cigarette group is also stabilized by the packaging according to the formation of the inner collar in the formation, so that the production of the cigarette or sealing block facilitates and above the sealing block forms a dimensionally stable unit. Side lobes connected to the inner front wall and the inner rear wall extending over a partial height are permanently connected to one another (at least partially overlapping, for example by gluing). According to the invention, the inner front wall extends over the full height, while the inner rear wall covers only a partial height, approximately up to half the height of the cigarette group. The inner collar is provided with inner side walls, which consist of mutually at least partially overlapping inner side tabs of the front wall on the one hand and the rear wall on the other.
The blanks for the inner collar are separated by a strip-shaped material web by transverse punch cuts. Resulting tongue-like projections can be eliminated by folding into the plane of the inner bottom wall or by separating as waste.

Packing for cigarettes 10 are usually designed so that a (aroma-and moisture-tight) film to form a sealing block 11, the cigarettes 10 and a cigarette group 12 of molded cigarettes 10 on all sides wrapped. Folding tabs are bonded together by gluing or thermal sealing while maintaining the sealing structure.

The sealing block 11 is expediently arranged in an outer pack 13 designed as a hard pack, in the present case in the form of a folding box or hinged lid pack. This widely used type of package consists of a (lower) box part 14 and a lid 15. The latter is pivotally connected to the box part 14 via a rear line joint 16. In Fig. 1, Fig. 2 the open position of the lid 15 is shown.

In the usual way, the box part consists of box front wall 17, opposite box rear wall 18, box side walls 19 and a bottom wall 20. Accordingly, the lid 15 lid front wall 21, lid rear wall 22, lid side walls 23 and end wall 24 on , In the Fig. 1 and Fig. 2 A further special feature is that the folding box 13 in the present case has no otherwise customary collar which extends in the area of the box front wall 17 and box side tabs 19 and projects out of the box part 14 , Instead, the lid 15 in the closed position immediately surrounds the sealing block 11, which has a corresponding rigidity.

The sealing block 11 or the film wrapping the cigarette group 12 is thermally sealable. The rectangular blank is folded so that partially overlapping fold tabs are joined together to form seal seams. In essence, the sealing block 11 is cuboid with block front wall 26, block back wall 27, block side walls 28, block end wall 29 and block bottom wall 30. In the embodiment according to Fig. 1 to Fig. 8 In the area of the upright block side walls 28, side seams 31 are formed in the region of substantially trapezoidal, partially overlapping folding flaps (so-called envelope folding). The block end wall 29 is free of folds. In the present case, a bottom seam 32 is likewise designed as a curve fold.

The sealing block 11 may alternatively ( Fig. 11 ) Have side folds 31 and a transverse seam 33. The side seams 31 in the region of the block side walls 28 consists of two interconnected in a transverse folding position material strips or lobes, which are folded over as a unit against the block side wall 28 ( Fig. 11, Fig. 12 ).

The block end wall 29 and the block bottom wall 30 are free of folds. Instead, a transverse finned seam, namely the transverse seam 33, is arranged in the area of the block rear wall 27, with a clear distance from the block bottom wall 30, preferably (approximately) at half the height. The transverse seam 22 extends into the region of the block sidewalls 28 with end pieces 34 due to a corresponding folding. The arrangement is such that first the transverse seam 33 is produced, then the lateral folds are carried out, so that the fin of the side seam 31 faces upwards the end piece 34 of the transverse seam 33 is folded and thus covers the end piece 34 ( Fig. 11, Fig. 12 ).

The sealing block 11 is provided with a substantially known opening aid. This extends in the area of the block end wall 29, in an adjacent region of the block front wall 26 and possibly with a portion in the block rear wall 27. By cross-sectional weakening of the film - perforation line 35 - a closure tab 36 is limited, in the open position ( Fig. 2 ) gives a corresponding discharge opening 37 for the cigarettes 10 free. The closure tab 36 and thus the removal opening 37 is completely covered by a closure label 38, which in the present case consists of a separate blank and by means of full-surface attached (permanent) adhesive on the outside of the closure tab 36 and - in Closed position - adheres to partial surfaces of the sealing block 11, namely at the edge regions of the removal opening 37, adhesive. The closure label 38 can be detected and actuated for (multiple) opening of the sealing block 11 by means of a glue-free grip tab 39 on a lower, free edge of the closure label 38. In closed position ( Fig. 1 ) is a front-side leg of the closure label 38 with handle 39 completely in the region of the lid 15 (lid front wall 21), ie above a closing edge 40 of the box front wall 17th

In the execution according to Fig. 11 the sealing block 11 is provided with an analogously designed opening mechanism, but the closure label 38 is provided with lateral, strip-like projections 41 and thus extends (approximately) over the full width of the block end wall 29.

In the foreground is a positioned within the sealing block 11, the cigarette group 12 partially surrounding support or protective device. This preferably consisting of a one-piece blank of (thin) cardboard body is hereinafter referred to as inner collar 42. In the present case, the basically known inner collar 42 is designed in such a way that increased dimensional stability and resistance to mechanical influences, in particular, are present in the lower region of the cigarette group.

In a first embodiment according to Fig. 1 to Fig. 8 the inner collar 42 consists of a blank ( Fig. 3 ) which is separated from a continuous web of material 43 by a transverse, contoured punching line 44. An inner front wall 45 is delimited from inner side flaps 46 by longitudinal fold lines 47. In the embodiment shown, the blank of the inner collar 42 is aligned with packages with bevelled edges 25 ("Oktag.onalpackung"). Therefore, two parallel longitudinal fold lines 47 are provided.

In a special way, an inner bottom wall 48 is formed, namely multi-layered due to partially overlapping folding tabs. Furthermore, a subsequent, upright portion of the inner front wall 45 is also formed multi-or two-ply, whereby an overall increased dimensional stability of the inner collar 42 is provided in a the inner bottom wall 48 facing area.

A part or a position of the inner bottom wall 48 is formed from a projection or a tongue-shaped bottom flap 49. This formed with rounded contours tab 49 of the blank for the inner collar 42 is formed by the contoured punching line 44. Opposite, namely in the region of an upper edge 50 of the inner collar 42, a (central) recess or recess 51 is created, the removal of cigarettes 10 at exposed discharge opening 37 of the sealing block 11 facilitates. The bottom flap 49 is positioned on the top of the inner bottom wall 48 due to appropriate folding steps, thus forming an inner layer with a partial coverage of the bottom surface.

Further layers or folding tabs of the inner bottom wall 48 are formed from partial regions of the inner front wall 45. This is provided in a lower region with a punching line 52, which is preferably mounted in the region of the material web 43 or at the same time as the separation of the inner collar 42. The punching line 52 is positioned and designed so that a further bottom tab 53 is formed, which is folded due to targeted folding steps in the plane of the inner bottom wall 48, in this case against the free bottom of the bottom flap 49. The punching line 52 is dimensioned so that in addition to the bottom tab 53 a transverse connecting tab 54 is provided as part of the inner front wall 45.

Bottom tabs 53 and connecting tabs 54 are delimited from each other by a transverse fold line 55. Furthermore, the connecting tab 54 is delimited from a bottom edge portion 56 of the inner front wall 45 by a further fold line 57. In a first folding step ( Fig. 4 ), the unit of bottom flaps 53 and connecting tabs 54 is folded into a downwardly directed intermediate folding position with partial abutment (outside) on the edge piece 56 ( Fig. 4 ). The dimensions and distances are chosen so that the further fold line 55 approximately at the level of the produced Interior bottom wall 48 is located. In a further folding step (by 90 °), the bottom tab 53 is now folded into the plane of the inner bottom wall 48 under contact with the previously folded bottom tab 49.

The folding flaps of the inner bottom wall 48 may be connected to each other by glue. In the present case, a glue-free connection is created by interlocking insertion tabs. Due to corresponding punches, a tongue 59 is created in the region of a fold line 58 for delimiting the bottom flap 49. This is in the described folding tongues - in an upright position ( Fig. 8 ) - inserted into a plug-in slot 60 which is arranged in the region of the fold line 55 and has a greater length than the edge of the tongue 59th

The (outer) bottom flap 53 of the inner bottom wall 48 is formed in a special way, namely with lateral tab-like extensions 61 which are delimited by a fold line 62 extending in a region between the longitudinal fold lines 47 from the remaining part of the bottom flap. The lugs 61 are after folding of the bottom flap 53 in the plane of the inner bottom wall 48 (FIG. Fig. 5 ), ie folded into an upright position so that they preferably extend in the plane of the inner side flaps 46. In the present exemplary embodiment, these are provided on the bottom side with a corner recess 63, in which the extension pieces 61 are fittingly received ( Fig. 6, Fig. 7 ), so that these extensions 61 extend in the plane of the inner side flaps 46.

The corner recesses 63 are formed by the correspondingly contoured punching line 44. In the region of the subsequent blank, this produces corresponding projections or end tabs 64 in the area of the inside side tabs 46. The end tabs 64 are folded inwards when the unit of cigarette group 12 and inner collar 42 is completed attached to the end surfaces of cigarettes (in the range of filters of the same).

The punching line 52 for the folding flaps associated with the inner bottom wall 48 leads to a substantially T-shaped recess 65 in the region of the inner front wall 45 and inner side tabs 46. The course of the punching line 52 is selected such that in a region facing the inner bottom wall 48, namely substantially corresponding to the connecting tabs 54, edge webs 66 for stabilizing the (folded) inner collar 42 in the region of the inner Front wall 45 stop.

In the manufacture of the sealing block is made of Fig. 4 to Fig. 6 apparent folding sequence observed. In the position according to Fig. 5 the lugs 61 are in the plane of the inner bottom wall 48. The front lobes 64 are brought into an intermediate fold position, namely are directed funnel-shaped outward. In this position, the formed cigarette group 12 is introduced from above into the predominantly folded inner collar 42. Thereafter, the final folding steps are performed, namely the erection of the lugs 61 and the folding of the end flaps 64 in the plane of an upper end face. Thereafter, the otherwise prepared or prepared foil blank is folded around the unit of cigarette group 12 and inner collar 42, wherein the folding tabs are joined together by thermal sealing. The sealing block 11 according to Fig. 7 is then introduced into the outer package, in this case in a folding box.

Also in the embodiment according to Fig. 9 to Fig. 11 the sealing block 11 is provided with an inner collar 42 which has a higher dimensional stability due to reinforcements in a region facing the inner bottom wall 48. The blank for the inner collar 42 is according to Fig. 9 also separated from a strip-shaped material web 43 by a transverse punching line 44. Analogous to the preceding exemplary embodiment, an (upper) edge, namely the upper edge 50, is provided by the punching line 44 with a recess 51 for facilitating the removal of cigarettes 10.

The inner front wall 45 of the inner collar 42 extends substantially over the full height of the cigarettes 10 and the cigarette group 12 to the inner bottom wall 48 in continuation of the inner front wall 45 includes a blank extension 67, the inner rear wall 68th in continuation of the inner front wall 45 and the inner bottom wall 48 and rear side tabs 69 - According to the inner side tabs 46 - forms. In the present embodiment, in the sense of an additional stabilization of the bottom-side portion of the inner collar 42 bottom corner tabs 70 are provided according to Fig. 9 are associated with the inner front wall 45 associated inner side tabs 46 and abut the folded inner collar 42 on the inner bottom wall 48.

The thus formed blank for the inner collar 42 is folded around the cigarette group 12 in such a way that a cup-shaped structure is created in a lower, bottom-side region. The inner rear wall 68 is erected and abuts against the back of the cigarette group 12. The rear side tabs 69 of the inner rear wall 68 abut against the outer side of the inner side tabs 46 and are preferably connected to them by glue - with an appropriate coating alternatively by thermal sealing. Accordingly, the cigarette group 12 is formed in a closed cross-sectional area facing the inner bottom wall 48, so that the cigarette group 12 is encircled and held around.

The thus formed unit of cigarette group 12 and inner collar 42 is in a sealing block 11 according to Fig. 11, Fig. 12 arranged in detail of the sealing block of the Fig. 7 deviates and is described above.

The design of the packing unit or the sealing block 11 is selected so that the inner rear wall 68 (including rear side tabs 69) terminate below the transverse seam 33. The transverse seam 33 thus extends above the cup-shaped part of the inner collar 42, so that accumulations of material layers are avoided.

The inner collar 42 may be provided in the region of the inner side walls with a material recess. In the embodiment according to 10 to FIG. 12 the inner side tabs 46 are provided with a recess 71 open to the free edge. This is formed by a corresponding punching preferably in the separation of the blank for the inner collar 42 of the web 43. Two different solutions are shown:

The punch 72 may be U-shaped with residual connections. In the further processing of the blank, in particular before the beginning of the folds, a corresponding piece of material 73 is separated as waste and removed. This results in a limited by a U-shaped edge recess 71 (right side in Fig. 9 ). Alternatively, the punch 72 may be formed so that an angular cut 74 is formed and the piece of material 73 is folded about a fold line 75 against the inner side flap 46 - preferably outside - ( Fig. 9 , Left). The recess 71 is preferably positioned so that the transverse seam 33 or its end pieces 34 lie (completely) in the region of the recess 71 (FIG. Fig. 12 ). In the alternative with folded piece of material 73, this lies above the recess 71.

In the example shown, moreover, the bottom flap 49 formed by the punching line 44 when making the blank is removed as a waste piece due to a corresponding weakening line 76. This is applied in the production of the blank. The tab 49 is separated in the further course of manufacture by tearing off the blank.

The thus formed sealing block 11 is accommodated in an outer pack 13, preferably in the embodiment as a folding box.
