Within the thus formed outer packing a block-shaped inner pack is arranged, in the embodiment as a sealing block 24 , The contents of the package, especially the cigarette group 11 , is on all sides of an interior blank 25 surrounded by foil, which is preferably due to its composition and moisture-resistant flavor. In addition, the material of the inner blank is 25 thermally sealable, so that flaps can be connected by heat and pressure.

A special feature of the sealing block 24 or the inner blank 25 is a reusable, reusable opening aid. This consists of an opening tab 26 holding a removal opening 27 exposed in an inner film or film layer. The opening tab 26 is present by a U-shaped weakening line 28 , namely a perforation, a continuous punching line or other suitable material weakening limited. When opening the sealing block 24 becomes the opening tab 26 with the help of an actuator, namely an actuating tab 29 , in the open position ( 6 ) brought.

The operating tab 29 is part of the interior blank 25 or part of an outer layer 30 of the interior blank 25 , The operating tab 29 is characterized by a substantially U-shaped weakening or punching line 31 limited. Furthermore, the operating tab 29 preferably over the entire surface by adhesive with the (outside of) the opening tab 26 connected. The operating tab 29 is larger than the opening tab 26 and covers these with a preferably formed on three sides (U-shaped) closure strip 32 , This is located at a removal opening 27 surrounding edge stripes 33 an inner layer 34 as a carrier of the opening tab 26 at. The operating tab 29 is at least in the area of the closure strip 32 provided with a permanent adhesive.

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

The interior blank 25 is specially designed in the area of the opening construction. The operating tab 29 is part of the outside situation 30 of single or multi-layered interior blank 25 , The removal opening 27 or the opening tab 26 are part of the inner layer 34 , At least in the area of the opening structure is the inner blank 25 from at least two films or at least two layers of a film laminate.

In the embodiment according to 3 . 4 consists of the inner blank 25 from a continuous two-ply film with outer layer 30 and inner layer 34 , In the area of the opening structure, moreover, in this exemplary embodiment, there is a piece of film 43 positioned, which between the layers 30 . 34 is embedded. The foil piece 26 (and the inner layer 34 ) has the opening tab 26 on. The foil piece 43 has larger dimensions than the opening tab 26 and as the operating tab 29 , namely extends into the area of the side strips 38 of the interior blank 25 , Only free ends of the weakening line 28 and the punching line 31 are outside the area of the film piece 43 so that a line joint forming in this area during opening next to the film piece 43 lies. The through the operating tab 29 detectable opening tab is therefore formed here 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 made of permanent adhesive is between the outer foil 30 and the foil piece 43 arranged. The edge strip 33 for the connection of the actuating tab 29 with the inner foil 34 or the film piece 43 is (exclusively) in the area of the film piece 43 educated. Manufacturing technology can be proceeded so that the film piece 43 Full surface provided with the permanent adhesive and so between the layers 30 . 34 of the interior blank 25 is positioned.

Preferably, the arrangement is such that the organs of the opening construction, so in particular the opening tab 26 and the operating tab 29 , in an upper area 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 interior blank 25 extends. The operating tab 29 This allows the consumer in an upper, exposed area of the sealing block 24 captured and over the inner end wall 36 forming a joint at the upper edge of the inner rear wall 37 be brought into an open position. The contents of the pack, namely the cigarette group 11 , lies in the area of the removal opening 27 across the full width of the inner end wall 36 and a sufficient portion of the inner front wall 35 free. For detecting the actuating tab 29 this is in the area of the inner front wall 35 in the middle with a grip tongue 45 Mistake. This is located in an adhesive-free area. The glue layer 44 is at least in the area of the grip tongue 45 left out ( 7 ). The grip tongue 45 is attached so that it is always above the box front wall 16 is, so can be freely recorded. In the embodiment according to 13 . 14 is the grip tongue 45 free in the area of the recess 43 the collar front wall 50 ,

A special opening structure is in 18 to 20 shown. Here is the interior cut 30 single-layered, optionally with sealing coatings. Innenseitg is on the inner blank 25 the foil piece 43 attached 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 in the same function and training in the area of the inner blank 25 positioned. The foil piece 43 has here a larger dimension, extends with sufficient length in the area of the inner front wall 35 and the inner rear wall 37 of the interior blank 25 , Preferably, the film piece 43 (almost) full surface through the glue layer 44 with the inside of the inner blank 25 connected. The foil 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 closed position.

Another special feature is the konstrukti ve training of the sealing block 24 or the folding of the inner blank 25 , There are different designs for the sealing block 24 proposed. At the in 8th . 9 illustrated embodiment is the inner blank 25 so to the contents of the pack or the cigarette group 11 folded over, that the side lobes 39 . 40 for the formation of inner sidewalls 38 folded like a box ( 9 ). The side lobes 39 . 40 cover each other in the plane of the sidewall 38 of the sealing block 24 , The folding flaps, namely side lobes 39 . 40 , here are connected to each other over the full length by thermal sealing.

The interior blank 25 is folded so that down, namely in the area of an interior bottom wall 42 , protruding folding flaps, namely parts of the horizontal stripes 41 of the interior blank 25 , are arranged in protruding position to form a fin fold 46 , In this area, the thermal sealing of the folding tabs of the horizontal stripes 41 without transfer of pressure and / or heat to the ends of the cigarettes 10 be transferred, namely by sealing jaws 47 , which are transverse to the sealing block 24 and outside the range of cigarettes 10 are moved against each other and the folding flaps of the fin fold 46 connect with each other. The transverse fins fold 46 is then against the inner bottom wall 42 folded. At the ends protruding gusset 48 Be up against the inside sidewalls 38 of the sealing block 24 folded (folded) 9 ).

To protect the contents of the package, namely the cigarettes 10 when sealing the lateral lobes 39 . 40 is inside the sealing block 24 arranged a cover which extends at least in the region of the inner side walls. It is in the present case an inner collar 49 ( 2 ), the cigarette group 11 partially surrounds. 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 become against lateral areas of the cigarette group 11 folded over and extend in the area of the inner side walls, ie in the area of the folded side lobes 39 . 40 , to cover the cigarette group 11 against heat and pressure. A border strip 52 of the inner collar 49 is against the back of the cigarette group 11 folded, so that these of a - in cross-section - C-shaped inner collar 49 is surrounded. A recess 53 in the area of the collar front wall 50 allows the removal of cigarettes 10 with the sealing block open 24 ( 6 ).

An alternative for the design of the sealing block 24 shows 16 combined with 17 , In this embodiment, also in the region of inner side walls, ie on both longitudinal sides, fin folds 54 formed, through appropriate folding of the side lobes 39 . 40 , As a result, in this area, too, the sealing of the folding flaps or side flaps 39 . 40 through sealed cheeks 55 done crosswise to front and back next to the cigarette group 11 are effective and heat as well as pressure without affecting the cigarettes 10 transferred to the folding flaps. The resulting fin folds or fin seams 54 are folded against the inside sidewalls ( 17 ). The bottom-side fin fold 46 is formed analogously to the described embodiment. Through the lateral fin folds 54 resulting gussets 56 are directed downwards against the inner side walls or side lobes 39 . 40 folded.

In this embodiment, it does not require the arrangement of an inner collar within the sealing block 24 , Instead, it's a folding box 12 trained outer pack with a standard collar 15 provided, as usual, in the box part 13 is positioned. The opening aid ( 12 ) is dimensionally matched to the structure of the outer package.

A special feature is the manufacturing process for the sealing block 24 ,

In a sealing block in the embodiment according to 9 becomes a blank for the inner collar 49 in the transverse direction of the formed cigarette group 11 supplied and placed on top of this. It will then be the collar side walls 51 folded in the downward direction. The unit of cigarette group 11 and inner collar 49 is then conveyed to the area of a blanking unit.

Here are prepared interior blanks 25 held, namely supplied in a (vertical) transverse plane. The cigarette group 11 is positioned so that filter ends point forward in the transport direction. These capture the interior cut 25 , In conjunction with guides or Faltorganen is due to the transport of the inner blank 25 U-shaped around cigarette group 11 and inner collar 49 folded around. The interior blank 25 is held so that the organs of the opening aid exactly from the cigarette group 11 be recorded.

The first U-folding step also folds front corner flaps. Thereafter, the folding of the side lobes takes place 39 . 40 and their sealing by transversely movable sealing jaws 57 , Then the fold is in the area of the inner bottom wall 42 executed, namely the production of Flossenfaltung 46 and their seal. Next is the fin fold 46 against the back in the conveying direction inside bottom wall 42 folded over and then the gussets 48 put into position. The so herge put sealing block 24 is suitably introduced into the outer package.

The procedure for the sealing block 24 in the execution according to 17 is designed analogously, the cigarette group 11 without inner collar 49 the prepared inner blank 25 recorded, without folding the corner lobes. In the subsequent sealing station, the protruding side lobes become 39 . 40 over the full length to form the fin fold 54 sealed by on both sides of the cigarette group 11 acting sealing jaws 55 , Thereafter, in the manner described, the folding in the region of the inner bottom wall 42 executed and the production of the sealed fin fold 46 ,

On the finished sealing block 24 eventually becomes a common collar 15 hung up. The unit of sealing block 24 and collar 15 is inserted in the outer pack.

The Exterior pack can also be designed in another way especially as a shell-and-slide pack or as a cap box.
