Packaging material are connected to one another by forming seams, in order to close the thus formed envelope made of packaging material, according to the preamble of claim 21.

The production of packs of cigarettes is known from practice, a group of cigarettes being arranged in an envelope made of a sealable plastic-based film material and the film material being sealed by forming seams in order to create a so-called sealing block in which the cigarettes are safely stored can. It is known to form or close the seams by sealing layers of the film material. It is also known that the seams can be sealed against the group of cigarettes by sealing overlapping folding flaps of the film material or as so-called fin seams without the pressure required during sealing being exerted on the overlapping layers of the film material acts on the cigarette group.

Packs of this type have basically proven their worth. However, in some markets or countries there are regulations that regulate the materials with which the cigarettes may come into contact as pack contents. In particular, it is not permitted in such countries for the cigarettes to come into contact with coated materials and / or sealing media (e.g. paint, glue, glue, etc.). The use of known packs of the type mentioned at the outset is therefore not possible, or only to a limited extent, in such countries.

The invention is explained below with reference to packs 10 for cigarettes 11. It goes without saying that the packs 10 are also suitable for other products in the cigarette industry.

In the context of the application, products of the cigarette industry are understood to mean tobacco products such as cigarettes, cigarillos and the like, but also novel tobacco products such as heat-not-burn products or liquid carriers for e-cigarettes.

In the pack 10 shown in FIGS. 1 and 2, a group 12 of cigarettes 11 is provided as the contents of the pack. The group 12 is wrapped in an envelope 13 made of a packaging material. A removal opening 14 can be closed by a closure means 15 which can be actuated several times.

This inner packing 16 or the envelope 13 has a large front side 17, a corresponding opposite large-area rear side 18, and narrow sides 19 connecting the front side 17 and the rear side 18 to one another. Furthermore, a bottom side 20 and a front side 21 are provided, each on the front side 17, back 18 and narrow sides 19.

The closure means 15 extends essentially over the entire end face 21 and is fastened with one end region to the rear side 18. Another end of the closure means 15 extends into the region of Front side 17. The closure means 15 covers the removal opening 14 on all sides. At a lower end of the closure means 15, a folding tab 22 is provided, which serves to open the closure means 15.

During the manufacture of the pack 10, the casing 13 is wrapped around the group 12 and tightly closed by forming seams 23 to form a so-called sealing block. As usual, several layers of the packaging material are connected to one another.

In the present case it is provided that folding flaps of the packaging material are brought to bear against one another in the area of the two narrow sides 19 and are connected to one another by a seam 23 in the overlapping area. The same takes place in the area of the rear side 18 of the casing 13.

2 shows that the seams 23 in the area of the narrow sides 19 are folded over after the folding tabs of the packaging material have been connected and placed against the narrow sides 19, the seams 23 being folded in the direction of the rear side 18.

The seams 23 form a closed envelope 13 in which the contents of the pack are protected from harmful influences. In the area of the removal opening 14, the casing 13 is closed by the closure means 15.

The inner packing 16 or envelope 13 according to FIG. 2 can be accommodated in an outer packing 24 according to FIG. 1. In the present case, the outer pack 24 is designed as a hinge-lid pack with a box part 25 and a lid 26 pivotably arranged thereon. The outer pack 24 can also have a collar 27.

Of course, it can also be provided that the outer pack 24 has a different construction. It is also conceivable that the outer pack 24 is missing. In this case, the terms pack 10, envelope 13 and inner pack 16 are to be used synonymously. To open the closure means 15 of the inner pack 16, the folding flap 22 is attached to an inside of a front wall of the lid 26, for example by gluing. In this way, the closure means 15 is automatically opened when the cover 26 is opened and automatically closed when the cover 26 is closed. Alternatively, it is conceivable, for example, that the closure means 15 of the inner pack 16 is opened and closed manually, for example by the consumer grasping the folding flap 22.

A special feature is that the closure means 15 consists of paper and is provided with an adhesive layer on the underside in order to close the removal opening 14. Here, for example, a PSA (Pressure Sensitive Adhesive) from UPM Raflatac (type RC13) can be used, which has a reduced adhesive force.

A further special feature of the closure means 15 made of paper can consist in the fact that it extends essentially over the entire end face 21, preferably over the entire area over the entire end face 21.

3 to 5 show three blanks 28 for wrappings 13 in a spread out, unfolded state. The areas of the blank for the individual side surfaces of the envelope 13 are delimited from one another by fold lines 29. At the edge there are front-side folding tabs 30 for the transverse seams and longitudinally folding tabs 31 for the longitudinal seams, the transverse seam and the longitudinal seams each being designed as fin seams.

Furthermore, FIGS. 3 to 5 show the arrangement of coatings made of cold glue 32, hot glue 33 and sealing wax 34. It is shown as an example that the cold glue 32 is applied punctiformly, the hot glue 33 over part of the surface and the sealing wax 34 over the entire surface on the folding tabs 30 and 31 to be connected is applied. The coatings for connecting the folding flaps 30, 31 are attached to one side of the blanks 28, namely on an inner side (facing the package contents).

Furthermore, FIGS. 3 to 5 show the position of a print mark 35 and the position of ventilation flaps 36. The blank 28 according to FIG. 5 also has a silicone coating 37 in the area of the folding flap 22. The Silicone coating 37 is applied on the outside and serves as a passivating agent (“deadener”) for the adhesive layer of the closure means.

It goes without saying that the above-described application patterns of the coatings are to be understood purely as examples and that other application patterns or coating patterns can also be used, for example the materials mentioned at the beginning.

FIG. 6 shows a conceivable structure of a device for producing the inner pack 16. A material web 39 is pulled off reels 38 and guided through a splicer 40. From there, the material web 39 runs through a pendulum storage device 41. This is followed by a web edge control 42.

Along the further conveying path 39 printing units 43, 44 are provided on both sides of the material web 39, with which the material web 39 can be treated in the process. A printing unit 43 below the material web 39 is used in the present case for coating and / or printing the material web 39. For example, (decorative) printing on the outside of the material web 39 and / or the application of the silicone coating 37 is conceivable. On the other side of the material web 39 a printing unit 44 is provided with which the adhesive 32, 33 or sealing wax 34 is applied to connect the folding tabs. It is also conceivable that the printing unit 44 is used for printing the inside of the material web 39, for example for printing the side of the material web 39 facing the package contents.

It goes without saying that the printing unit or units 43, 44 can consist of one or more printing units. It is also understood that, depending on the design of the inner pack 16, printing units 43, 44 can be arranged on one of the two sides of the material web 39.

Following the printing units 43, 44, the coated material web 39 runs through a drying unit 45. The drying unit 45 serves to dry the applied coatings and can preferably work on a UV basis. The material web 39 prepared so far in the manufacturing process is then transported by a feed roller 46 into the area of two label devices 47, where the material web 39 is provided with the closure means 15. It is conceivable that a different number of label devices 47 can also be provided.

The material web 39 provided with the closure means 15 is then passed through a punching unit 48, where punchings can be made on the material web 39 to form the removal openings 14 and / or the ventilation flaps 36.

The continuous material web 39 then arrives in the region of a forming shoulder 49 over which it is passed to form a tube around the supplied package contents.

The group 12 of cigarettes 11 is arranged in a tray 50 made of packaging material, the tray 50 surrounding the group 12 on several sides. The tray 50 can be formed from a rigid packaging material such as thick paper or cardboard.

The groups 12 with tray 50 are transported with a longitudinal extension transverse to the transport direction according to arrow 51 and wrapped in a tube-like manner in a material web 39 made of the packaging material. The individual groups 12 with tray 50 are arranged at a distance from one another within the tube of the material web 39. A continuous seam 23 is then formed which extends parallel to the transport direction according to arrow 51 and runs in the area of what will later be the rear side 18 of the inner pack 16. This seam 23 is also referred to below as a transverse seam, since it extends transversely to the longitudinal extension of the inner pack 16.

In order to form the transverse seam, pressing or sealing tools 52, which are basically known from the prior art, are arranged below the packing strip. Furthermore, tools 53 are provided which serve to fold the transverse seam against the casing 13. There is a Pressure member 54 is provided, which presses the material web 39 against the groups 12 or trays 50 and thereby smooths the material web 39.

Fig. 7 shows the feeding of the groups 13 in the tray 50 along the pack path on a larger scale as well as the wrapping of the groups 13 in the tray 50 in the continuous material web 39 in the area of the forming shoulder 49 Dots of glue 57 are used to connect the folding flaps. Gluing units 55 serve to apply glue for the folding tabs 31 for the longitudinal seam and glue units 56 are used to apply glue to the folding tabs 30 for the transverse seam. 8 shows the arrangement of the gluing units 55, 56 in detail. The glue units 55 are arranged in a row in several groups and the glue units 56 are arranged on the edge of the material web 39.

In the next step, the material web 39 is divided between the individual groups 12 and thus a separation is carried out. In this case, seams 23 are also formed, which run in a direction transverse to the transport direction according to arrow 51. These seams 23 are located in the area of the narrow sides 19 of the inner pack 16 and are also called longitudinal seams, since their extension runs parallel to the longitudinal axis of the inner pack 16.

9 shows the separation of the inner packs 16. Here, rotating rollers are arranged on both sides of the pack web. A first roller 58 has cutting blades 59 which are arranged on the circumference of roller 58 and which work together with a counterpart 60 on counter roller 61 in order to cut the packaging material between groups 12. The counterpart 60 on the counter roll 61 can be designed like the cutting knife 59 or as a simple block on which the cutting knife 59 comes to rest in order to cut through the packaging material.

On both sides of the severing knife 59 or the counterpart 60, transverse pressers or transverse sealing members 62 are formed with which the seams 23 are formed. With the aid of the device, an inner pack 16 can be produced from a packaging material based on paper. The packaging material can be pure paper or else coated paper, for example with an inner layer made of paper and a coating or outer layer made of waxy material or aluminum. The variants described at the beginning are also conceivable. A paint application on the inside or the outside is also conceivable, both over the entire surface and in areas. The connection of the folding flaps in the area of the seams 23 can be done by glue or other sealing media. The glue patterns and types can vary. The tools that match the glue are used to connect the folding flaps.

If closure means 15 made of paper are also used, the inner pack 16 can be entirely free of plastic.

As an alternative to applying glue, it is also conceivable to use a pre-coated material web 39 made of paper, which is provided with a coating in the packaging process (online). Using digital printing units e.g. from the company Xaar (UV printing units XAAR1002 / XAAR1003U, inkjet printing systems, piezo print heads Xaar5601 or Xaar Print Bar System) or other manufacturers, the coating can be applied over the entire surface or directly after the web edge control 42. The following options are particularly conceivable:

- Inside sealing wax application to connect the seams 23,

Outside or inside paint application for printing the material web 39,

Application of a silicone layer 37 on the outside in the area of the folding flap 22 of the closure means 15.

With the drying unit 45, the applied coatings (colored sealing wax or silicone layer) can be cured. The closure means 15 are then attached and the material web 39 is formed into a tube over the forming shoulder 49 and closed with appropriate pressure or sealing tools 52. To support the sealing tools 52, additional preheating of the material web 39 be provided, for example in front of the transverse sealing tools on the material web 39 or by a heated forming shoulder 49.

10 and 11 show a variant of the first embodiment of the pack 10. The envelope 13 and the closure means 15 are formed essentially as in the first embodiment, but the seams 23 in the region of the narrow sides 19 are formed as envelope folds. The transverse seam is arranged in the area of the bottom side 20 and not in the area of the rear side 18, but as a fin seam as in the first exemplary embodiment.

FIG. 12 shows an inexpensive alternative to the solution according to FIG. 11, namely with a partial envelope 13 which, starting from the end face 21, extends along the narrow sides 19, the rear side 18 and the front side 17, but ends at a distance from the bottom side 20. Instead of a transverse seam, a glue connection is provided between the tray 50 and the lower edge of the casing 13 in order to close the casing 13.

In contrast to the first exemplary embodiment, all the variants shown in FIGS. 10 to 12 dispense with a collar 27. Instead, the casings 13 contain a tray 50 which takes on the role of the collar 27 and helps stabilize the lid 26 when it is closed.

FIG. 13 shows a first step of the packaging process, the blank 28 shown indicating the glue connections for the version according to FIG. 11 and according to FIG. Here, the tray 50 with the group 12 is wrapped in the blank 28 with the front side 19 first and the blank 28 is wrapped around the group 12 in the longitudinal direction. 14 shows the design of the seam 23 as a fin seam, which is then folded over into the bottom side 20 (FIG. 15). Then the folding flaps are folded in the area of the narrow sides 19 and the seams 23 are formed there.

11 to 15 consistently show the use of glue which is applied in the form of glue dots 57 to the folding tabs or to the edge of the blank 28. It goes without saying that all others are also described in the application Variants of the material connection can be used, for example also a sealing wax.

16 and 17 show a variant of the pack 10 or envelope 13 shown in FIGS. 1 and 2. First of all, it is noticeable that in the exemplary embodiment shown in FIGS. 16 and 17 the collar 27 shown in the exemplary embodiment according to FIGS is missing.

The waiver of the collar 27 can, for. B. for reasons of sustainability, in that the material consumption in the production of the packs 10 is reduced. Of course, this also leads to a reduction in the manufacturing costs of the pack 10.

The closing process of the cover 26 is problematic when a collar 27 is dispensed with. The applicant has recognized that during the closing of the cover 26 it can happen that the side walls of the cover 26 collide with the seams 23 of the casing 13 that are folded back, if these are not held by a collar 27 on the narrow sides 19 of the casing 13.

In order to solve this problem, it is proposed to fold the seams 23 in the region of the narrow sides 19 of the casing 13 in the direction of the front side 17 and to connect them to the narrow sides 19 of the casing 13 before the casing 13 is inserted into a pack 10. This ensures that the side walls of the lid 26 can slide past the seams 23 of the casing 13 in the region of the narrow sides 19 when the lid 26 is closed. The connection between the seams 23 and the covering 13 can serve to overcome the restoring forces of the folded seams 23. This could, for. B. a hotmelt gluing 33 (hot glue track or glue point) can be used.

In summary, it should be stated that a material web 39 based on paper is used in all variants. This can be provided on the outside with an aluminum layer, so that instead of a pure paper web, a material web 39 made of a paper-aluminum laminate is processed. Conceivable is also that a material web 39 made of a metallized paper is used, that is, a paper web with a vapor-deposited metal layer. The material web 39 can be coated in the process or can also be delivered pre-coated. This also applies to the other coatings, for example with sealing wax. This can be applied (partially or fully), namely either during the packaging process or in advance.

If the use of a paper-based material web 39 is not desired or necessary, the following material webs 39, for example, can also be used:

- Triplex film with (white) OPP, aluminum and PET layers,

- Triplex film with PP, aluminum and PET layer,

- Triplex film with (white printed) OPP, aluminum and PET layer,

- Duplex film with (white or printed) PP and metallized PET layer.

The foils as well as the material web 39 can preferably be white on the side facing the package contents (that is to say on the inside). Be it by using a suitable material or by applying the appropriate paint.
