Description

Cigarette pack and method for producing cigarette packs Description

The invention relates to a folding box for lumpy packaged goods, in particular for cigarettes, consisting of box part and lid, wherein the package contents, in particular a cigarette group surrounded by an inner wrapper preferably aroma- and moisture-proof, thermally sealable film and within the thus formed sealing block an inner collar resilient material, in particular cardboard, is arranged with edge tabs in the region of lateral sealing seams of the inner wrapper, wherein the inner wrapper in the region of an upper end wall has a resealable opening aid, consisting of a locking tab in the region of a removal opening and a provided with adhesive, reusable operating tab. Furthermore, the invention relates to a method for producing such (cigarette) packs.

The invention is concerned with improvements and developments of packages of the aforementioned embodiment. In particular, it is an improvement of the protection of the arranged inside the sealing film cigarettes and an improved opening aid for the sealing block, as well as conditions for efficient production of the packs. To solve this problem, the package according to the invention is characterized by the following features:

a) laterally projecting folding tabs of the blank of the inner envelope are folded under mutual partial overlap against the sides of the cigarette block and connected to each other by thermal sealing,

b) folding flaps of the inner blank formed in the region of the bottom surface are brought together to form a fin fold and by thermal sealing joining together to form a fin, wherein the fin is folded against the bottom surface,

c) the inner collar in the sealing block is formed without bottom tabs.

The invention is based on the finding that the thermal and mechanical stress of the cigarettes in the region of the bottom surface is particularly great because of the open end surfaces of the cigarettes. According to the invention, therefore, a folding and sealing for the sealable inner sheath is selected, which does not transmit thermal and mechanical stresses to the ends of the cigarettes. According to the invention, a fin seam is formed in which heat and pressure can be transferred to protruding folding flaps, that is to say without impairing the cigarettes. In the area of the side surfaces overlapping folding tabs are connected by sealing against the side legs of the inner collar. The inner collar is designed as a simple blank, in particular with a U-shaped cross section, namely with support or protective tabs only in the region of the narrow side walls, but without any tab in the region of the bottom wall. Alternatively, it is also possible to form fin seams laterally. In this case, it requires no inner collar. Rather, a customary for folding boxes collar is positioned on the outside of the sealing block.

A (stand-alone) feature is the reusable opening aid of the inner covering in the area of one end face. The operating tab is through the

Foil of the inner envelope or formed by a layer of this film itself.

Removal opening and locking tab are in the area of another location of the

Inside cut or formed in the area of a separate inner film. This ensures that the outside of the inner blank remains free of resting tabs.

The inventive method for producing the pack or the film block with cigarettes comprises the steps of U-shaped folding over a blank of the inner wrap around the cigarette group, in particular with Inner collar, the folding of folding flaps in the area of the side walls and the sealing of the same, the subsequent production of the fin seam in the area of the bottom and folding over the fin seam. The thus formed film block is processed in the usual way as the contents of a folding box.

Fig. 20 is a detail of a package with the lid open in vertical section, analogous to FIG. 15, for a further embodiment.

The packs presented in the present case are primarily intended for receiving cigarettes 10, wherein a number of cigarettes 10 are combined in formation into a cigarette group 11 as package contents. In construction, the (cigarette) pack consists of an outer pack and an inner pack. The outer package is a folding box 12 with a standard construction, namely with a (lower) box part 13 and a lid 14 and optionally a collar 15 (FIG. 11). Box part 13 and cover 14 consist of a one-piece blank (Fig. 1) with areas for a box front wall 16, bottom wall 17, box rear wall 18, lid rear wall 19, end wall 20 and lid front wall 21. box side walls 22 and Lid side walls 23 (Fig. 5, Fig. 6) each consist of overlapping side lobes, so they are double-layered.

Within the thus formed outer pack, a block-shaped inner pack is arranged, specifically in the form of a sealing block 24. The contents of the pack, in particular the cigarette group 11, is surrounded on all sides by an inner blank 25 made of film which, due to its composition, is preferably free of moisture and aroma. In addition, the material of the inner blank 25 is thermally sealable, so that folding flaps can be joined together by heat and pressure. A special feature of the sealing block 24 and the inner blank 25 is a reusable, ie re-closable opening aid. This consists of an opening tab 26 which exposes a removal opening 27 in an inner film or film layer. The opening tab 26 is presently limited by a U-shaped weakening line 28, namely a perforation, a continuous punching line or other suitable material weakening. When the sealing block 24 is opened, the opening tab 26 is brought into the open position (FIG. 6) by means of an actuating member, namely an actuating tab 29.

The actuating tab 29 is part of the inner blank 25 or part of an outer layer 30 of the inner blank 25. The actuating tab 29 is bounded by a substantially U-shaped weakening or punching line 31. Furthermore, the actuating tab 29 is preferably connected to the (outer side of the) opening tab 26 over its entire surface by means of adhesive. The actuating tab 29 is larger than the opening tab 26 and covers it with a preferably formed on three sides (U-shaped) closure strip 32. This is located on a discharge opening 27 surrounding edge strip 33 of an inner layer 34 as a support of the opening tab 26 at. The actuating tab 29 is provided at least in the region of the closure strip 32 with a permanently acting adhesive.

The blank for the sealing block 24, so the inner blank 25 is divided by (imaginary) fold lines in areas for an inner front wall 35, an inner end wall 36 and an inner rear wall 37. Over the full length of the inner blank 25 extend on both sides Side strips to form interconnected side flaps 39, 40. These form inner side flaps 38. At free ends of the elongated inner blank 25 are transverse strips 41 which extend over the full width of the inner panel 25. The transverse strips 41 form an inner bottom wall 42 in a special design.

The inner blank 25 is specially designed in the region of the opening construction. The actuating tab 29 is part of the outer layer 30 of the single or multi-layer inner blank 25. The removal opening 27 or the Opening tabs 26 are part of the inner layer 34. At least in the region of the opening structure, the inner blank 25 consists of at least two foils or at least two layers of a foil laminate. In the exemplary embodiment according to FIGS. 3, 4, the inner blank 25 consists of a continuous two-ply foil with outer ply 30 and inner ply 34. In the area of the opening structure, furthermore, in this exemplary embodiment, a foil piece 43 is positioned which is embedded between the plies 30, 34 is. The film piece 26 (and the inner layer 34) has the opening tab 26. The foil piece 43 has larger dimensions than the opening tab 26 and as the operating tab 29, namely extends into the region of the side strips 38 of the inner panel 25. Only free ends of the weakening line 28 and the punching line 31 are outside the range of the film piece 43, so a forming in this area when opening forming line joint is adjacent to the film piece 43. The detectable by the operating tab 29 opening tab is thus formed here in two layers, on the one hand consists of a corresponding part of the inner layer 34 and on the other hand from a corresponding, equal part of the film piece 43. A glue layer 44 of permanent adhesive is disposed between the outer film 30 and the film piece 43 , The edge strip 33 for the connection of the actuating lug 29 with the inner foil 34 or the foil piece 43 is (exclusively) formed in the region of the foil piece 43. In terms of manufacturing technology, it is possible to proceed in such a way that the film piece 43 is provided over its entire area with the permanent adhesive and is thus positioned between the layers 30, 34 of the inner blank 25.

Preferably, the arrangement is such that the organs of the opening construction, ie in particular the opening tab 26 and the actuating tab 29, in an upper region of the inner front wall 35, across the inner end wall 36 and with an end portion in the inner rear wall 37 of the inner blank 25 extends. The actuating tab 29 can thereby be detected by the consumer in an upper, exposed region of the sealing block 24 and brought about the inner end wall 36 to form a hinge at the upper edge of the inner rear wall 37 in an open position. Of the Package contents, namely the cigarette group 11, is exposed in the region of the removal opening 27 over the full width of the inner end wall 36 and a sufficient portion of the inner front wall 35. For detecting the actuating tab 29, this is provided centrally in the region of the inner front wall 35 with a grip tongue 45. This is located in an adhesive-free area. The glue layer 44 is recessed at least in the area of the grip tongue 45 (FIG. 7). The grip tongue 45 is mounted so that it is always above the box front wall 16, so it can be freely detected. In the exemplary embodiment according to FIGS. 13, 14, the grip tongue 45 is exposed in the region of the recess 43 of the collar front wall 50.

A particular opening structure is shown in FIGS. 18 to 20. Here, the inner blank 30 is formed in one layer, optionally with sealing coatings. Innenseitg the film piece 43 is attached to the inner blank 25 in the area of the opening aid. The opening tab 26 and the removal opening 27 are in this embodiment, only part of the film piece 43. The operating tab 29 is positioned in the same function and training in the region of the inner panel 25. The film piece 43 here has a larger dimension, extending with sufficient length in the region of the inner front wall 35 and the inner rear wall 37 of the inner panel 25. Preferably, the film piece 43 (almost) over the entire surface through the glue layer 44 with the inside of the inner panel 25th connected. The film piece 43 forms in this embodiment, the edge strip 33 for limiting the removal opening 27 and for repeatedly fixing the operating tab on the film piece 43 in the closed position.

Another special feature is the structural design of the sealing block 24 and the folding of the inner blank 25. Different designs for the sealing block 24 are proposed. In the embodiment illustrated in FIGS. 8, 9, the inner blank 25 is folded around the package contents or cigarette group 11 such that the side flaps 39, 40 are folded like a cover to form inner side walls 38 (FIG. 9). The side flaps 39, 40 overlap each other in the plane of the side wall 38 of the Sealing block 24. The folding flaps, namely side flaps 39, 40, are here connected to each other over the full length by thermal sealing.

The inner blank 25 is folded so that below, namely in the region of an inner bottom wall 42, protruding folding tabs, namely parts of the transverse strips 41 of

Inner blank 25, are arranged in protruding position to form a

Fins folding 46. In this area, the thermal sealing of the

Folding tabs of the transverse strips 41 are transferred without transfer of pressure and / or heat to the ends of the cigarettes 10, namely by sealing jaws 47, which are moved transversely to the sealing block 24 and outside the range of cigarettes 10 against each other and connect the folding tabs of the fins fold 46 together. The transversely projecting fin fold 46 is then folded over against the inner bottom wall 42. At the ends protruding gusset

48 are folded up against the inner side walls 38 of the sealing block 24 (Figure 9).

To protect the package contents, namely the cigarettes 10, when sealing the side tabs 39, 40, a cover is arranged within the sealing block 24, which extends at least in the region of the inner side walls. In the present case, this is an inner collar 49 (FIG. 2) which partially surrounds the cigarette group 11. The inner collar 49 extends in this embodiment over the full length or height of the cigarette group 11 with a collar front wall 50 in the front area. Collar side walls 51 are folded over against lateral areas of the cigarette group 11 and extend in the region of the inner side walls, ie in the region of the folded side tabs 39, 40, for covering the cigarette group 11 against heat and pressure. An edge strip 52 of the inner collar 49 is folded against the back of the cigarette group 11 so that it is surrounded by a - in cross-section - C-shaped inner collar 49. A recess 53 in the region of the collar front wall 50 makes it possible to remove the cigarettes 10 when the sealing block 24 is open (FIG. 6).

An alternative for the design of the sealing block 24 is shown in FIG. 16 in conjunction with FIG. 17. In this embodiment, also in the region of inner As a result, the sealing of the folding tabs or side tabs 39, 40 by sealing jaws 55, which are transverse to the front and back sides, can also take place in this area the cigarette group 11 are effective and transmit heat and pressure without affecting the cigarettes 10 on the folding flaps. The resulting fin folds or fin seams 54 are folded over against the inner side walls (FIG. 17). The bottom-side fin fold 46 is formed analogously to the described embodiment. Zips 56 formed by the lateral fin folds 54 are folded downwards against the inner side walls or side tabs 39, 40.

In this embodiment, it is not necessary to arrange an inner collar within the sealing block 24. Instead, the outer package formed as a folding box 12 is provided with a standard collar 15 which, as usual, is positioned in the box part 13. The opening aid (FIG. 12) is adapted in terms of dimensions to the structure of the outer package. A special feature is the production method for the sealing block 24.

In a sealing block in the embodiment according to FIG. 9, a blank for the inner collar 49 is fed in the transverse direction to the formed cigarette group 11 and placed on top thereof. Then, the collar side walls 51 are folded in the downward direction. The unit of cigarette group 11 and inner collar 49 is then conveyed to the area of a trimming unit.

Here prepared inner blanks 25 are kept ready, namely supplied in a (vertical) transverse plane. The cigarette group 11 is positioned so that filter ends point forward in the direction of transport. These grasp the inner blank 25. In conjunction with guides or folding organs, the inner blank 25 is folded in a U-shape around the cigarette group 11 and inner collar 49 due to the transport. The inner blank 25 is held so that the Organs of the opening aid are accurately detected by the cigarette group 11.

The first U-folding step also folds front corner flaps. Thereafter, the folding of the side flaps 39. 40 and their sealing by transversely movable sealing jaws 57. Then, the folding in the region of the interior

Bottom wall 42 running, namely the production of the fin fold 46 and its seal. Next, the fin fold 46 against the in

Conveying direction rear inner bottom wall 42 folded over and then brought the gussets 48 in the position. The sealing block 24 thus produced is suitably inserted into the outer package.

The method for the sealing block 24 in the embodiment according to FIG. 17 is designed analogously, wherein the cigarette group 11 without inner collar 49 detects the prepared inner blank 25, without folding the corner tabs. In the subsequent sealing station, the projecting side tabs 39, 40 over the full length to form the fin fold 54 sealed by acting on both sides of the cigarette group 1 1 sealing jaws 55. Thereafter, in the described manner, the folding in the region of the inner bottom wall 42 is executed and the manufacture of the sealed fin fold 46.

On the finished sealing block 24 finally a conventional collar 15 is placed. The unit of sealing block 24 and collar 15 is inserted into the outer package.

The outer package may also be formed in other ways, in particular as a shell-and-slide package or as a cap box. LIST OF REFERENCE NUMBERS
