Description

The invention relates to a cigarette pack with the features of the preamble of claim 1.

Cigarette packs with an inner collar or with an inner pack within a cigarette block - cigarette group with a foil wrapper - are primarily used for sealed packs, i.e. for cigarette packs in which the cigarette group with inner collar or inner tray is surrounded on all sides by a dense, thermally sealable film. The "sealing block" thus formed is usually arranged in a hard pack, preferably in a conventional hinged box.

An example of this version of a cigarette packing is in DE 10 2011 119 344 A1 shown and described. A formed cigarette group is initially (partially) surrounded by the inner collar, preferably with a large front wall, lateral, transverse side tabs or side walls and preferably a bottom wall. The inner collar is accordingly tray-shaped and U-shaped in cross section and open at least in the area of an upper or end face in order to enable the cigarettes to be removed.

The sealing film surrounding the unit consisting of the cigarette group and the inner collar can be provided with sealed sealing seams, preferably in the area of narrow areas of the cuboid pack. The sealing seams are designed as a fin seam and are preferably arranged in the region of narrow, upright inner side walls of the sealing block.

Furthermore, an opening aid is provided in the front area, namely a reusable locking tab with a removal opening of the sealing block.

A generic cigarette lease is from the DE 10 2010 019 867 known.

The invention relates to cigarette packs of the aforementioned or a similar design. It is a matter of securing the selected cigarette formation - usually with at least two rows of cigarettes - during the complex manufacturing process of the sealing block.

To achieve this object, the cigarette pack is designed with the features of claim 1.

The cigarette group arranged in the respective formation is accordingly combined by an additional, cross-directional holding means, in particular in the form of a holding strip, so that the cigarette formation is preserved during transport during the manufacture of the sealing block. The holding strip or a holding band can directly surround the formed cigarette group. An embodiment in which the holding means surrounds the unit consisting of the cigarette group and the inner collar or inner tray is advantageous. In this case, the holding strip can completely surround the inner tray or can be positioned as a strip only in the region of the (rear) open surface of the inner collar transversely to the cigarettes and connected to the inner collar, in particular the upright side tabs. This creates a dimensionally stable unit that guarantees the formation of the cigarettes in the further packaging steps until the cigarette block or the sealing block is completed.

Another measure relates to the stabilization of the cigarette or sealing block in such a way that the outer pack can be designed as a hinged box without a conventional hinged box collar. For this purpose, fins are folded from the side sealing seams of the sealing block to the front of the pack, so that additional stability is ensured in the area of upright, front edges of the pack or the sealing block. This can also be increased by affixing a closure label across the full width of the end face to a front face.

It is preferably a matter of forming cigarette packs of the seal pack type, that is to say with an inner pack or a cigarette block 10 in the form of a seal pack. The cuboid cigarette block 10 sits in an outer pack 11 in the hard pack design, in the present case in the form of a hinged box, consisting of a (lower) box part 12 and a lid 13. The latter is pivotally connected to the box part 12 via a transverse line joint 14. Overall, the hinged box 11 is designed in a conventional manner, but in the present case without the otherwise usual collar or frame in the region of the box part 12.

The cigarette block 10 consists of a dense, thermally sealable film. Fig. 8 shows, for example, a blank for such a cigarette block 10 with front wall 15, rear wall 16, side walls 17 and end wall 18 and opposite bottom wall 19.

The blank 21 of the cigarette block 10 separated from a film web 20 is in the present case folded around a cigarette group 22 in such a way that upright closure seams 23 are formed on the two side walls 17 as a fin seam. Furthermore, a transverse seam 24 is essentially formed to connect partial areas of the rear wall 16. The transverse seam 24 extends into the region of the side walls 17. Each fin seam consists of two adjacent strips of material which are permanently connected to one another by thermal sealing. The resulting double-layer fin is folded against a packing surface. In the present example ( 1 to 3 ) the fins of the side closure seams 23 are folded forward, that is to say towards the front wall 15 of the cigarette block 10. The fins of the closure seams 23 are fixed at least in an upper end area by thermal sealing and / or by gluing to the relevant surface of the side wall 17, so that an overall multi-layer area of the cigarette block 10 with locally increased dimensional stability is created.

Within the cigarette block 10, the cigarettes of the cigarette group 22 are stored in an inner collar or in a tray-like inner pack 25, preferably made of thin cardboard or a comparable material. The cigarettes of the cigarette group 22 are arranged in a specific, predetermined formation, in the present exemplary embodiment ( Fig. 13, Fig. 14 ) forming three rows of seven or six cigarettes. It is important to stabilize the formation of the cigarette group 22 within the inner package 25 for further processing.

The cigarette group 22 is assigned a holding means or holding member which is effective at least after the cigarette group has been introduced into the inner pack 25. In the exemplary embodiment shown, this is designed in the manner of a tray, namely with a front wall or tray front wall 26, which points downward during the manufacturing process. Laterally transverse or upward side walls or tray tabs 27, 28 are attached to the latter, which are preferably located extend the full length of the tray front wall 26. Furthermore, a transverse tray bottom 29 is provided, against which the cigarettes of the cigarette group 22 rest after their introduction into the inner pack 25 with their free ends. The tray bottom 29 in the present case consists of folding and plug-in tabs which are connected to one another without adhesive.

In order to also ensure complex formations of the cigarette group 22 within the presently tray-like inner pack 25 which is open on at least two sides, the cigarette group 22 is stabilized by at least one transverse holding means. A strip of material can surround the cigarette group 22 directly as a closed, annular holding means. However, the holding means is preferably attached to the inner pack 25 so that its shape is stabilized and the formation of the cigarette group 22 is thereby fixed. The present embodiment of the tray-shaped inner pack 25 is particularly concerned with stabilizing the lateral tray tabs 27, 28.

In the preferred embodiment shown, the tray tabs 27, 28 are connected by a transverse holding means. According to the exemplary embodiment, this consists in 9, 10 from a holding strip 30, which is connected to the tray tabs 27, 28 and extends transversely to the cigarettes of the cigarette group 22, such that the tray tabs 27, 28 are fixed in an exact, upright, parallel position.

The tether 30 according to 9, 10 is attached to the inner pack 25 with transverse or angled legs 31, by gluing or by (thermal) sealing. In the exemplary embodiment shown, the holding strip 30 is provided with a glue field 32 in the region of the legs 31 on the side facing the tray tabs 27, 28. The free length of the holding strip 30 between the legs 31 corresponds to the transverse dimension of the cigarette group 22 or the distance between the erected, parallel tray tabs 27, 28 from one another.

The legs 31 are preferably connected to the outside of the tray tabs 27, 28. Suitable adhesives for the field 32 are adhesives which can be activated by means of heat and / or pressure, for example hot-melt glue. PSA adhesives (Pressure Sensitive Adhesives) are also particularly suitable. It is a permanent adhesive glue applied as a hot melt. The glue fields 32 are applied to the holding strip 30 before it is connected to the inner pack 25. A single holding strip 30 is sufficient in the embodiment of the inner packing 25 shown. The holding strip 30 is expediently in the region of the transition between cigarette filters 33 and the actual one Arranged cigarette ( Fig. 10 ).

The holding strip (s) 30 can be formed as part of the inner pack 25. In the embodiment according to 11 to 14 the holding strip 30 is defined as part of a blank for the inner pack 25, namely by two parallel punched lines 34 as a boundary. The punching lines 34 extend across the tray front wall 26 into the region of the tray tabs 27, 28, to the middle of the same. Here, a fold line 35 is defined as the end of the holding strip 30. When the inner pack 25 is manufactured, in particular when the tray tabs 27, 28 are erected, the retaining strip 30 is also folded, with end pieces of the retaining strip 30 serving as connecting legs 36 in the region of the tray tabs 27, 28. These are erected along the fold line 35, so that the connecting legs 36 bear against the inside of the tray tabs 27, 28 and are connected to them. The holding strip 30 formed from the tray front wall 26 extends in the plane of the free rear side of the inner pack 25 ( Fig. 12 ). A (glue) connection 37 is attached between the connection legs 36 on the one hand and the free portion of the tray tabs 27, 28 ( Fig. 13, Fig. 14 ). In this embodiment, the holding strip 30 is expediently arranged approximately in the central region of the free rear of the inner pack 25.

15 and 16 show a modified embodiment with a holding strip 30, which is analogous to the embodiment of FIG 9, 10 is appropriate. In this exemplary embodiment, the holding strip 30 is connected to the inner pack 25 — tray tabs 27, 28 — without glue, namely in particular by means of thermal sealing. The holding strip 30 consists here overall of a sealable film or of a carrier strip which is provided with a sealable coating - sealing wax - at least on the side facing the inner pack 25. The connecting surfaces of the legs 31 with the tray tabs 27, 28 can be fixed directly on the (uncoated) outside of the tray tabs 27, 28 (version Fig. 16 , Left). For an increased durability of the connection, the inner packing 25 as a whole, that is to say the complete blank, or locally in the region of the legs 31 can be provided with a sealable coating. Alternatively, namely as shown in Fig. 16 , on the right, can be provided in the area of the holding strip 30, a connecting strip 38 connected to this, which consists of sealable material (film) or has an outer, sealable coating (sealing wax). The legs 31 are connected to erected end pieces 39 of the connecting strip 38, which abut the tray tabs 27, 28, in particular in the area of a sealing surface 47.

As a further alternative, a holding strip can also be designed as a band running all around, the ends of which are connected to one another in a suitable manner (adhesive bonding, sealing). The overlapping connection ends of such a holding strip are preferably arranged in the region of the tray front wall 26, but in such a way that the connection tab or the connection point lies completely in the region of a box front wall of the box part 12.

The manufacture of the units from the inner pack 25 and the cigarette group 22 or the manufacture of the cigarette block 10 is preferably carried out as follows: Cuts for the inner pack 25 are separated from a tray web 40, specifically by means of transverse, contoured separating cuts to form a tab 41 for the tray bottom 29. Correspondingly, a contoured recess 42 is created on the opposite side, which enables the removal of individual cigarettes from the cigarette block 10.

The holding strips 30 are preferably separated from a continuous strip web 42 when they are designed as separate, independent strips ( Fig. 4 ). The glue fields 32 (or sealable coatings) are attached to the continuous strip web 42 in the correct position. The holding strips 30 are therefore separated in a complete, processable design.

After the tray-like inner pack 25 has been produced, when an independent holding strip 30 is used, the cigarettes formed as a cigarette group 22 are first introduced into the inner pack 25 via the open (front) side ( Fig. 9 ). The holding strip 30 is then attached and fixed to the inner pack 25 in one way or another. With an execution according to 11 to 14 , i.e. with a holding strip 30 as part of the inner pack 25, this is first erected with the holding strip 30 into the finished position ( Fig. 12 ). Thereafter, the cigarette group 22 is inserted over the open side, expediently with corresponding, mouthpiece-like guide members, which rule out the hooking of the cigarettes with the holding strip 30. The connecting legs 36 can then be glued to the tray tabs 27, 28.

The blank 21 of the cigarette block 10 is folded around the unit consisting of the cigarette group 22 and the inner pack 25 in a conventional manner, usually starting with a U-shaped folding step over the end wall 18 Technology of DE 10 2011 119 344 A1 ,

The cigarette block 10 is preferably designed as a sealing block and consists of the thermally sealable blank 21 according to FIG Fig. 8 with a multi-use removal opening 43 which extends in an upper region of the front wall 15 of the cigarette block 10 and the adjacent end wall 18 ( Fig. 2 ). The removal opening 43 can be closed by means of a reusable flap or a closure label 44, specifically because of the corresponding adhesive on the inside.

A special feature is that the closure label 44 extends over the full width of the end wall 18 of the Cigarette blocks 10 extends, preferably with side extensions 45 of the closure label 44. These extensions 45 are permanently bonded to the front wall 18 and adjacent areas of the front wall 15 and rear wall 16 of the cigarette block. The strip-shaped extension pieces 45 are delimited by perforation lines 46 from the actuating part of the closure label 44, so that the extension pieces 45 always remain in the connection position with the cigarette block 10.

As a result, the shape of the cigarette block 10 is increased, particularly in the lateral region of the upper side. In addition (or alternatively), the tabs of the side closure seams 23, which are connected to one another by seals, are folded over toward the front wall 15 and accordingly lie against the front half of the side walls 17. At least an upper, front-side area of the tabs of the closure seams 23 is connected to the area of the side wall 17 by thermal sealing and / or by gluing, so that here too an increased dimensional stability is created. As a result, the outer pack 11 can be designed as a hinged box without the usual collar or frame in the box part ( 1, 2 ).

The outer pack 11 is preferably designed as a hinged box (without a collar). The present cigarette block 10 can, however, also be used in other (hard) packs, for example of the "Shell and Slide" type or in a cap box. <B> LIST OF REFERENCES: </ b> 10 cigarette block 36 connecting leg 11 overpack 37 (Glue) connection 12 box part 38 connecting strips 13 cover 39 tail 14 line joint 40 Tray-Bahn 15 front wall 41 insertion flap 16 rear wall 42 panel web 17 Side wall 43 removal opening 18 bulkhead 44 closure label 19 bottom wall 45 extension 20 sheet 46 perforation 21 cut 47 sealing surface 22 cigarette group 23 closing seam 24 cross seam 25 interior package 26 Tray front wall 27 Tray cloth 28 Tray cloth 29 Tray bottom 30 holding strips 31 leg 32 Leimfeld 33 cigarette filter 34 cut line 35 fold line
