Description

Cigarette pack and method and apparatus for making the same

description

The invention relates to packs with an outer wrapping made of film, in particular cigarette packs, which can be removed with the participation of a tear strip which is attached to the latter and in particular extends transversely to the longitudinal extent of the pack around the pack. Furthermore, the invention relates to a method and a device for producing such packs with an outer casing.

Cigarette packs often have a pack feature that indicates after the first use of a pack that the pack has already been opened or has been used. Such a packaging feature can be used, for example, to prevent a third party from opening the respective cigarette pack after removing the outer wrapper, removing or replacing the cigarette, and then providing the pack with an outer wrapper again, without the user being able to recognize this. Such a packing feature can be, for example, a tax label which is attached to the cigarette packet in such a way that it tears open when the cigarette packet is opened. However, tax stamps are not required in all countries, so that it is not seldom that they are not attached to the packaging. In these cases, the tax label is therefore omitted as the carrier of the information "already opened / still unopened".

Proceeding from this, it is an object of the present invention to provide packs of the type mentioned at the outset in which a user of the respective pack is able to recognize whether the pack has already been used with the aid of a pack feature which does not or only slightly disturbs the overall appearance thereof and which can hardly be manipulated . The invention is also based on the object of specifying a method and a device for producing such packs. This object is achieved by a pack with the features of claim 1, a method with the features of claim 14 and an apparatus with the features of claim 22.

A (cigarette) pack according to the invention with an outer wrapper of the type mentioned at the outset is therefore characterized in that the outer wrapper and / or the tear strip is connected in a non-detachable manner by means of an adhesive portion, in particular made of hot melt, to a section of the pack which extends along at least one line of weakness of the (remaining) package is separable, so that this piece of piece adheres to the outer wrapping and / or the tear strip when the outer wrapping is removed and is removed together with the latter.

According to the invention, it is accordingly provided, on the one hand, that when the outer wrapper is removed from the pack and outer wrapper by a user for the first time, a section of the pack is automatically or inevitably removed, since the section is permanently connected to the outer wrapper and / or the tear strip. The absence of this section then serves as an indication or feature for the first use of the pack. On the other hand, it is particularly advantageously provided that the detachable section can be detached exactly along at least one line of weakness delimiting the section. The result of this is that when the section is removed, one or more clear tear-off edges are produced which do not significantly disrupt the aesthetics of the pack. Without such a defined tear-off edge, a part of an unpredictable size and shape would / could be torn off in an uncontrolled manner. The result would be aesthetically disadvantageous, since irregular tear-off edges. In addition, there would be the danger that packing areas on which important additional information is applied (warning notices, code surface, etc.) would also be torn off.

In particular, cuboidal, preferably from a dimensionally stable package blank, for example made of cardboard, folded packages (in particular hinge-lid packages) are provided in this manner according to the invention with such a feature for indicating a first use.

Such packs generally have one (at least) (large-area) front wall and rear wall, each two (upright, parallel with a distance from one another) arranged) connect narrow side walls with each other, as well as an end wall and a bottom wall.

As far as the in particular also rectangular outer wrapper is concerned, it preferably completely surrounds the package and is formed from a film blank and folded around the package, with the formation of walls corresponding to the corresponding walls of the package with (at least) front wall, rear wall, two the Front wall and narrow side walls connecting the rear wall as well as front wall and bottom wall.

The separable section is preferably part of one of two narrow side walls of the pack.

In particular, on a narrow side wall, which is opposite a narrow side wall of the outer casing, which (at least) in a wall section is formed by overlapping two side tabs - inner side tabs and outer side tabs - of the outer casing or of the film cut thereof, in two layers.

The adhesive portion connecting the section and the outer covering and / or the tear strip can then be arranged, for example, on a region of the narrow side wall of the package which is covered by the double-layer region of the outer covering formed by the inner side tabs and the outer side tabs. The portion of adhesive would lie on the one hand on the outside of the narrow side wall of the pack and on the other hand on the inside of the inner side flap of the outer wrapper (pointing to the pack) and / or on the tear strip arranged on the inner side of the outer wrapper (showing the pack), namely on the inside (pointing to the pack). In particular, in each case on or in the region of a free edge of the side flap of the outer covering at which the tear strip ends.

Insofar as the adhesive portion according to one of the variants according to the invention indicated above connects both the tear strip attached (on the inside) to the outer wrapping and the outer wrapper with the detachable section - by contacting the tear strip on the one hand and the detachable section on the other - the adhesive portion can preferably the tear strip across its length Extend at least on one side, preferably on both sides, so that the area (s) of the adhesive portion projecting beyond the tear strip additionally - by contacting the film on the one hand and the detachable section on the other - the film or outer wrapper with the detachable part Section connects / connect.

As far as the detachable section is concerned, it can preferably be located on an edge region of the package blank and comprise at least one (upright) edge of the same.

That wall of the pack, the part of which forms the separable part, in particular a narrow side wall, is preferably formed by an inner and an outer folding tab of the pack or of the pack blank, the inner and the outer folding tab being folded over one another with (at least partial) overlap, and wherein the detachable section is part of the outer folding flap, in particular in this case comprising an (upright) edge of the same.

The detachable section can be detachable along a preferably U-shaped weakening line that includes an edge of an (outer) folding tab of the pack, or along a circular or elliptical weakening line that also has in particular weakened line sections, or along several weakening lines that result in a waffle-like weakening pattern. But other line shapes are of course also conceivable.

The weakening line (s) can be formed from perforations or from scratches or creases.

According to the invention, it can further be provided that the outer folding flap of the pack in the region of the detachable section is not connected to the inner folding flap or is not fixed thereon. This would ensure, among other things, that a portion of the full thickness or material thickness of the outer folding tab is detached from the pack.

Alternatively, the detachable section (usually together with the rest of the outer folding flap) can also be glued to the lower folding flap. In this case will usually (but not necessarily) only remove an upper part of the outer folding flap as part of the package when the outer wrapping is removed.

If a section is cut off in the thickness of the outer folding flap, a view of the inner folding flap is free for a user. In such a case, it can be advantageous, in order to draw the user's gaze directly to the absence of the detachable section, if the inner folding flap on the outside of one of at least one other area of the pack or the pack cut, in particular in the area of the Outside of the outer folding flap, in which it covers the detachable section, has a different design. In particular, a different color or one or more different image objects, such as one or more symbols or one or more alphanumeric characters.

Alternatively, it can also be provided that the inner folding tab on its outside at least in an area that is covered by the detachable section, one of at least one other area on the outside of the inside folding tab, preferably in another area that covers the section that can be separated surrounds covered area, has a different design, in particular a different color or one or more picture objects, such as one or more symbols or one or more alphanumeric characters,

Specifically, provision can be made, for example, to provide the outside of the inner folding tab completely or at least or only in the area thereof covered by the detachable section with a layer of paint (which has a signal effect), in particular with a lacquer.

As far as the outer covering is concerned, in one embodiment of the invention it has a preferably edge-side, in particular U-shaped recess in or in a region of a double-layer narrow side wall, through which a tab of the tear strip extends. The portion of adhesive that connects the film and / or the tear strip to the detachable section is at least partially in the region of the recess or extends through the recess.

A method according to the invention for producing the packs defined above is characterized by the following measures: a) a continuous film web with tear strips attached thereto or individual packs is / are provided in the area of an adhesive station with the adhesive portions, in particular made of hot melt adhesive, by an adhesive unit,

b) from the continuous film web, film cuts for the outer wrapping of the pack are cut off at a cutting station,

c) the cut blanks are folded at a subsequent folding station with a folding unit, in particular a folding turret, in each case around a pack provided with at least one weakening line, along which the separable part of the pack can be separated, so that the adhesive portion separates the separable part of the pack with the outer covering and / or the tear strip connects.

The following additional measures can be provided in a further development of this method:

a) the individual packs are conveyed to the adhesive unit in succession by means of an (endless) conveyor in a first relative position,

b) the packs are each pivoted in the area of the gluing unit by means of a pivoting unit, in particular by lifting the (endless) conveyor from the first relative position into another, second relative position in which the gluing unit is preferably arranged above the conveying plane of the (endless) conveyor in each case applies the portion of adhesive to the detachable section of the package which is arranged in particular on a narrow side of the package.

After the adhesive portion has been applied, the packs are preferably pivoted back into the first relative position by the pivoting unit, in particular while putting the packs back on the (endless) conveyor, and conveyed further by means of the (endless) conveyor.

Depending on the type of adhesive used, the adhesive portion of the respective package can be connected, for example in the area of the folding station, by supplying heat and / or pressure to the adhesive portion with the detachable portion on the one hand and the outer covering and / or the tear strip on the other hand and, if necessary, smoothing it out will.

It can further be provided that the quality of the adhesive portion or the connection of the adhesive portion between the detachable section and the film or tear strip is achieved by means of check one or more cameras, preferably in the area of a subsequent shrinking station at which the outer wrapper of the respective package is shrunk. Heat / pressure could also be applied to the respective adhesive portion at this shrinking station.

A device according to the invention for producing the packs defined above is accordingly characterized by:

a) an adhesive station, in the area of which a continuous film web with tear strips attached thereto or individual packs in each case can be provided with the adhesive portions, in particular made of hot-melt adhesive, by an adhesive unit,

b) a cutting station, in the area of which film cuts for the outer wrapping of the pack can be separated from the continuous film web,

c) a folding station with a folding unit, in particular a folding turret, in the area of which cuts can be folded around a package provided with at least one weakening line, along which the separable part of the package can be separated, so that the adhesive portion is the separable part of the package with the outer covering and / or the tear strip connects.

Fig. 18 shows the detail XVIII of Fig. 17 in an enlarged view.

Packs 10 for sensitive consumer goods, cf. 1, in particular for cigarettes, are often surrounded by an outer wrapping 11 made of film to protect the contents of the pack. Pack 10 and outer casing 1 1 conceptually form a pack unit. The exemplary embodiments shown in the figures relate to cigarette packs 10 made of thin cardboard. Specifically, a hinge-lid pack or cap box is shown.

As standard, this is folded from a package blank made of cardboard or other dimensionally stable material, with the formation of a (larger) rear wall 12, front wall 13, (smaller area) narrow side walls 14, 15, bottom wall 16 and end wall 17.

The pack 10 has, in a known manner, a lower box part 20 for receiving the cigarettes and a cover 18 which is pivotably attached to the latter via a line joint 19.

In a form known per se, the front wall 13 is formed in two parts (from top to bottom), namely with a lower box part front wall 13a and an upper lid front wall 13b.

The same applies to the narrow side walls 14 and 15, which are each divided into a lower box part narrow side wall 14a, 15a and an upper lid narrow side wall 14b, 15b.

A pack of cigarettes, not shown, is usually contained in the pack 10 as the pack content.

In the area of the narrow side walls 14, 15, the pack 10 is formed in two layers. Each narrow side wall 14, 15 is namely in each case formed by inner and outer, interconnected folding tabs of the package 10 or the package blank, which have been folded over one another in the manufacturing process, cf. for example inner and outer folding tabs 21a and 21b of the chess part part narrow side wall 14a in FIG. 4.

The outer sheathing 11 surrounding the pack 10, which in the present case is also cuboid, consists of a (transparent) film blank 38, cf. for example Fig. 16, which completely surrounds the package 10.

The outer wrapper 11 is folded around the pack 10 in the present packaging unit in such a way that a first - in the present case single-layer - narrow side wall 22 of the outer wrapper 11 is opposite the narrow side wall 14 of the pack 10 and forms a closed covering or covering therefor.

A second narrow side wall 23, which is opposite to the first and is arranged at a distance parallel to this, is made in two layers in some areas, since there are side tabs there 24a, 24b of the film blank 38 overlap and are connected to one another, cf. also Fig. 7.

Complex folds, in this case envelope folds, are formed in the region of a bottom wall 25 and an end wall 26 of the outer casing 11. A front wall 27 and a rear wall 28 cover (single-layer) the respective front wall 13 or rear wall 12 of the pack 10 and are respectively opposite them.

To open the pack 10 when it is used for the first time, the outer covering 11 is removed in whole or in part. For this purpose, an opening aid is provided in the form of a tear thread or tear strip 29.

The tear strip 29 preferably extends all around or around the pack 10, in the present case in the region of the front wall 27, rear wall 28 and the narrow side walls 22, 23 of the outer casing 11, specifically in a horizontal plane. Presently along a central plane. However, it goes without saying that this arrangement of the tear strip 29 is not mandatory.

The tear strip 29 is continuously connected on the inside to the outer covering 11 or to the blank 38 of the outer covering 11, preferably by gluing.

A grip piece or a grip tab 30 is formed on a free end of the tear strip 29 for gripping the tear strip 29 when the package unit comprising the package 10 and the outer casing 11 is opened. By grasping this grip tab 30 or pulling the tear strip 29, the tear strip 29 continuously cuts through the film of the outer wrapping 11 on both sides. In the present example, two cap-shaped partial wrappings are produced after the latter has been removed, which can be pulled off the side of the pack 10.

In a special way, the package 10 in the alternative shown in FIG. 1 has a (small-sized) detachable section 31 which, as described at the outset, when the outer covering 11 is removed or when the tear-off strip 29 is pulled, with the formation of defined tear-off edges from the rest the package 10 is removed, together with the outer wrapper 11 and the tear strip 29. The absence of this section 31 after removal of the outer covering 11 then serves as an indication or feature for the first use of the package 10 or the package unit. In the manner according to the invention, cf. Even the other explanations below, which result in defined tear-off edges, do not significantly disrupt the packaging aesthetics or their appearance. In addition, there is no danger that unplanned packaging areas, on which important additional information is attached (warning notices, code surface, etc.) may also be torn off.

In the alternative according to FIG. 1, the section 31 is part of the outer folding flap 21a of the narrow side wall 14 of the pack 10, namely an edge-side part of the same. The detachable section 31 is delimited from the rest of the folding tab 21a or the pack 10 by a line of weakness 32, for example perforation, scoring or scoring.

In the example of FIG. 1, the weakening line 32 is U-shaped, the (free) edge of the folding tab 21a running along the connecting line of the free legs of the U-shaped weakening line 32. In other words, the detachable section 31 is located on the edge region of the outer folding flap 21a and comprises one or the free edge 33 thereof.

The detachable section 31 is (directly) non-detachably connected to the tear strip 29 and additionally to the adjacent film of the outer wrapper 11 via an adhesive portion 34, in the present case made of (reactivable) hot melt adhesive. Of course, other types of adhesive can also be used.

For this purpose, the adhesive portion 34 is made wider than the tear strip 29 (based on its width dimension transverse to its longitudinal extent). The adhesive portion 34 therefore projects beyond the tear strip 29 on both sides thereof (upwards and downwards).

This inseparable connection of the detachable section 31 on the one hand and the outer covering 11 and tear strip 29 on the other hand by the adhesive portion 34 leads to the fact that when the outer covering 11 is removed, in particular when the tear strip 29 is pulled off, the detachable section 31 along the weakening line 32 is defined with Tear-off edge is torn off or removed, cf. Fig. 5. In order to avoid, when possible, the detachable section 31 a fiber tear through the material of the folding tab 21a parallel to its x / y extension or to the outside thereof, the embodiment of FIG. 1 provides for the detachable section 31 with the one below it not to connect or glue inner folding tab 21b.

A (usual) gluing of the folding tabs 21a, 21b to one another does not take place, or at least only outside of this sub-area, at least in the partial area of the inner folding tab 21b covered by the detachable section 31.

In the alternative shown in FIG. 2, a removable section 3T is arranged on the other narrow side wall 15 of the pack 10, likewise on the edge side. The narrow side wall 15 is formed in the region of its box part narrow side wall 15a - similar to the narrow side wall 14 - in two layers, namely formed by two folded flaps 36a, 36b which are connected to one another and connected to one another. Here too, the section 31 ′ includes an edge, namely the edge 35 of the outer folding tab 36a of the narrow side wall 15.

In contrast to the narrow side wall 22 of the outer casing 11 opposite the narrow side wall 14 of the pack 10, the narrow side wall 23 of the outer casing 11 associated with the narrow side wall 15 of the pack 10 is formed in two layers at least in one area, cf. above.

In order to enable good bonding of a corresponding adhesive portion 34 'to the detachable section 3T in this case as well, the adhesive portion 34' is relative to the corresponding side tabs 24a, 24b which cause the double-layered structure

Outer sheath 11 is arranged so that it extends into the U-shaped recess 37 in the film blank 38 or at least partially extends through it, through which the grip tab 30 extends.

The portion of adhesive 34 'rests on the one hand on the portion 3T, on the other hand on the inside of the outer side tab 24a and the tear strip 29 attached to it and connects them, cf. Fig. 7. In contrast to the alternative in FIG. 1, the outer folding flap 36a of the narrow side wall 15 is, however, firmly connected to the inner folding flap 36b lying underneath, so that a (deliberate) fiber tear occurs in the region of the part 3T, cf. Fig. 8.

9, 10 a further alternative is shown, in which the detachable section 31 "is also part of the narrow side wall 15, but is not - as in FIGS. 7, 8 - connected to the inside of the outer side tab 24a, but in the double-layer region of the narrow side wall 23 of the outer covering 11 via the adhesive portion 34 ″ with the inside of the inner side tab 24b of the outer covering 11 and with the tear strip 29 arranged on this inside.

The outer side tab 24a extends above the inner side tab 24b in the area of the separable section 31 "or in the area in which it is connected to the side tab 24b via the adhesive portion 34".

The outer side tab 24a protrudes beyond the edge of the package 10 to form the grip tab 30 formed at the free end.

In this alternative, when the grip tab 30 is gripped and the tear-off strip 29 is pulled off, the entire tear-off strip 29 is first removed all around the packaging unit or the outer casing 11, with the outer casing 11 being separated, without the section 31 "which can be separated along the weakening line 32" being removed at first until the end of the tear strip 29 assigned to or connected to the inner side tab 24b is torn off from the outer wrapper 11 or the package 10.

13 and 14 show further alternatives of detachable sections 3T "and 31" ".

13, the line of weakness 32 "'is circular with residual webs 39a, 39b. This circular shape again prevents in a very special way unwanted further tearing out of the packing or narrow side wall material when the section 3T" is removed. 14, several lines of weakness 32 "" are introduced in a waffle-like manner over the detachable section 31 "". Here, a square portion of adhesive ensures the appropriate adhesive connection.

The technique shown in FIG. 15 is particularly suitable for the production of a package according to FIGS. 1-14. The schematic representation includes different variants of this technique.

In a manufacturing section, not shown, the packs 10 are first manufactured in a manner known per se in a packaging machine, not shown, for producing such packs 10.

The respective weakening lines 32, 32 'etc. can be introduced into the blanks 53 used to produce the packs 10 during the ongoing production process, cf. below. Alternatively, however, these may have already been introduced into the prefabricated blanks 53 used in the packaging machine as part of a separate production.

If this takes place in the ongoing production, this could happen, for example, in the area of a cutting apparatus 61, cf. 17, 18. The cutting apparatus 61 has a cutting magazine 55 in which there is a stack 54 of cuts 53.

The blanks 53 of the blank stack 54 are separated in the blanking apparatus 61 and fed into the further manufacturing process. Such cutting devices are known per se.

For example, they can have a punching and / or embossing tool 56, which has a cutting edge 57 which is adapted to the contour of the weakening line (s) 32, 32 'etc. which is to be introduced.

Such a tool can also be provided at the same time, for example to introduce a further embossing / punching with a further punching or embossing cutting edge 58, for example a support for a collar of the pack 10. For this purpose, such a punching and / or embossing tool 56 usually has a rotationally driven punching roll 59, on the circumference of which the punching cutting edge 57 and, if appropriate, additionally the punching cutting edge 58 can be arranged, as well as a counter roller 60.

After the packs 10 have been produced in the packaging machine, they are transferred to an (endless) conveyor 40 which in the present case conveys the packs 10 in a horizontal plane for further handling.

The conveyor 40 conveys the packs 10 individually in a first variant to an adhesive station 41 with, in particular, an adhesive unit 43 comprising one or more adhesive application valves 42. In the present case, this is initially arranged with its respective longitudinal axis in a horizontal plane and, in the present case, oriented transversely to its longitudinal extent in relation to the conveying direction .

In the area of the adhesive station 41, the packs 10 are attached to a known pivoting unit 44, cf. for example WO 2010/121682, pivoted out of its horizontal orientation or relative position into a second, in the present case vertical relative position, in particular while lifting off the conveying plane or conveying path of the conveyor 10, in which one of the narrow side walls 14, 15 of the pack 10 points upwards ( and lies in a horizontal plane).

In this position, the adhesive portion 34, 34 ', etc. is applied to the narrow side wall 14 or 15 by the adhesive unit 43.

The pivoting unit 44 then pivots the respective pack 10 erected back into the first relative position or the horizontal plane.

Alternatively, the use of such a swivel unit 44 can also be dispensed with. In this case, the adhesive unit 43 would, for example — as shown in dash-dot lines in FIG. 15 — provide the corresponding narrow side wall 14 or 15 (arranged in the vertical plane) with the adhesive portion 34 from a position arranged obliquely above the respective package 10. In the further course, the conveyor 40 then conveys the individual packs 10 in the direction of a folding station 46 with a folding unit 47, in the present case with a rotating folding turret.

In the area of the folding station 46, the individual packs 10 are transferred in a known manner to the folding turret 47 in a known manner for the production of the respective outer covering 11, each taking along a film blank 38 held upstream at a cutting station 48 transversely to the conveying plane of the packs 10, or respectively in a pocket 49 provided inserted into it. The individual film blanks 38 are separated into individual film blanks 38 in the region of the cutting station 48, namely separated from a continuous film web 51.

In the area of the folding turret 47, the respective foil blank 38 is then folded around the pack 10 in the further course of forming the outer covering 11. The folding takes place in such a way that the adhesive portion 34, 34 'etc. can ensure that the respective film cut 38 or the respective outer covering 11 and / or the tear strip 29 is glued to the corresponding narrow side wall 14 or 15 of the pack 10.

In the exemplary embodiment shown, the sealing units 45 are used as standard in order to connect the side tabs 24a, 24b of the outer casing 11, which are arranged radially on the outside in the pockets 49 of the folding turret 47.

By means of the sealing units 45, the respective hot glue adhesive portion, insofar as this is arranged in the region of the side tabs 24a, 24b or the narrow side wall 23, could then additionally be supplied, in particular for reactivating the same, in particular for the detachable section 31, 3T etc. on the one hand and the film of the outer covering 11 and / or the tear strip 29 on the other hand to be firmly connected to one another and, if necessary, to smooth the adhesive portion 34, 34 'etc.

The packs 10 with the outer covering 11 are then transferred from the folding turret 47 to a shrinking station 50. In the area of this shrinking station 50, the quality of the adhesive portion 34, 34 'etc. or the connection of the adhesive portion 34, 34' etc. with the detachable section 31, 3T etc. and the outer casing 11 or the tear strip 29 can be determined by means of one or more Cameras 62 are checked. In the area of the shrinking station 50, the outer covering 11 is further shrunk or subjected to shrinking measures in a manner known per se.

As an alternative to the above-described application of the adhesive portions 34, 34 ', etc. to the narrow side walls 14, 15 of the packs 10, it can also be provided that the continuous foil web 51, which is separated into individual foil blanks 38 in the region of the cutting station 48, with the adhesive portions 34 , 34 ', etc., for example by means of a contact adhesive valve 52.
