Description

The invention relates to a pack of two packing parts, namely an outer pack with at least one front wall, namely outer front wall and an inner part with at least one front wall, which is connected by means of a mounted on the front wall connecting strap or joint flap with the outer front wall inside wherein parts of the outer package, namely subpackets, are pivotable about a bottom hinge relative to each other in an open and a closed position.

A cigarette pack with two pivotally connected part packs is known by WO 2006/061563 , The two sub-packages are pivotally connected to each other in the area of a common bottom wall. In the open position, the two part packs are arranged in a spread position. The part packs together form an outer pack. This is connected in the region of an outer front wall with an inner part of the pack, namely with a modified collar. This has the connecting or joint flap, which is formed as part or as an extension of a collar front wall at the bottom of the collar. In order to bring the joint flap in the operative position, it requires a folding over of the extension against the collar front wall. A in this position of the joint flap upwardly directed edge strip is connected to the inside of the outer pack by gluing.

Another cigarette pack with two hinged part packs is out DE 201 07 274 U1 known; the connecting or joint flap is formed here as part of the inner front wall.

It is an object of the invention to further develop a package of the aforementioned embodiment for particular cigarettes so that a production on largely conventional, efficient packaging machines is possible. The object underlying the invention is therefore to make the blanks for the outer packing and / or for the inner part machine-friendly.

To solve this problem, the package according to the invention is characterized in that the hinge or connecting strap formed as part of the (inner) front wall of the inner pack or the inner part by an approximately U-shaped punching and a free, a top or end wall the pack facing end-side portion is attached to the outside on the inside of the outer front wall, in particular by gluing.

In the invention, therefore, due to the arrangement and configuration of the joint or joint flap, a folding of the tab or a part as an intermediate step in the manufacture of the package is avoided. Rather, the procedure according to the invention is that the inner packing or a separate inner part is manufactured in a first working step and attached to the contents of the package - cigarette block - or folded around it. In a second step, the formed inner unit is wrapped by a blank of the outer package. The packaging steps expediently proceed in successive or adjacent folding turrets of essentially conventional design. The connecting means, namely glue, is mounted on the outside of the joint flap, so that when folding the blank for the outer pack it is connected without additional work step with the joint flap.

A further feature according to the invention consists in that the inner packing surrounds the contents of the package at least in the region of a front side, in the region of a rear side and in the region of the bottom, and preferably also has side walls of overlapping inside side tabs. Preferably, the inner pack is formed approximately cup-shaped, wherein the inner front wall acts in the upper region as (conventional) collar of a pack of the type folding box. The inner package and the outer package are connected to one another in the area of rear walls, that is to say the inner rear wall and the outer rear wall, in particular by bonding in an upper, frontal region and at the bottom in a bottom region. A rear edge facing the transverse edge of the outer bottom wall forms the line joint for pivoting the part packs of the outer pack.

According to a further feature of the invention, an inner part - instead of an inner packing - designed in the manner of a collar and provided with preferably two adjacent joint or joint plates. Between these, a web is formed centrally to stabilize the front wall of the inner part or of the collar.

The cuboidal packs shown as exemplary embodiments serve to receive cigarettes 10 as package contents. Usually, the cigarettes are 10 as Cigarette group 11 and surrounded by an inner blank 12 of paper, tin or the like to form a cigarette block thirteenth

The pack for receiving the cigarette block 13 consists of at least two packing parts, namely an inner part and an outer part. The latter is formed as the package contents largely surrounding outer package 14. In the embodiment according to Fig. 1 to Fig. 10 the inner part is formed as an inner pack 15 which is partially or completely surrounded by the outer pack 14.

Fig. 1 shows an expanded blank for the outer pack 14 with longitudinally successive areas for an outer front wall 16, a subsequent outer bottom wall 17 and an outer rear wall 18. At the free end of the outer rear wall 18, an inner tab 19 is attached and On both sides of the outer front wall 16 and the outer rear wall 18 further folding tabs are mounted, namely outer side tabs 22, 23, which together in the closed position of the pack, an outer side wall 21 of the outside -Packung 14 form on opposite narrow sides. However, the mutually associated outer side tabs 22, 23 are not connected to each other by gluing, but freely relative to each other movable.

On the front wall 20 side corner tabs 24 are attached. Opposite end-corner flaps 25 are arranged in extension of the outer side tabs 23. Furthermore, bottom corner tabs 26 are mounted in extension of the outer bottom wall 17.

The from the blank according to Fig. 1 formed outer pack 14 consists of two part packs 27, 28. The front part pack 27 consists essentially of the outer front wall 16, the (transversely folded) outer side flap 22, the transverse folded end wall 20 and the inside of the outside Side flaps 22 adjacent side corner flaps 24. These are connected to the outer side flaps 22 to form a box-shaped sub-package 27. Also, the bottom corner tabs 26 are internally connected to the outer side tabs 22 and thus part of the front part of the package 27. The back part of package 28 consists of the outer rear wall 18, the folded outer side tabs 23, the transverse inner tabs 19 and End-corner tabs 25, the inside connected to the inner tab 19 by gluing are. The outer bottom wall 17 is connected via a joint, namely via a transversely directed bottom edge 29 with the partial pack 28. The two sub-packages 27, 28 are therefore pivotable about this bottom edge 29 to each other ( Fig. 8 ).

The outer pack 14, in particular the front-side part pack 27, acts together with an inner part. This is according to the embodiment Fig. 1 to Fig. 10 formed as an inner package 15, for example, with a blank according to Fig. 2 , This is designed so that the package contents, ie the cigarette group 11 and the cigarette block 13, is largely enclosed by the inner packing 15, namely except for an upper, front and frontal area. The blank of the inner package 15 consists of an inner front wall 31, a longitudinally adjoining inner bottom wall 32 and a subsequent inner rear wall 33. Inner side walls 34 of the inner package 15 consist of laterally on the inner front wall 31 and inside Rear wall 33 attached folding flaps, namely inner side tabs 35 and inner side tabs 36. These cover each other to form the inner side walls 34 and are connected to each other. The side tabs 35 of the front wall 31 are outside.

The inner pack 15 is formed due to the design of the blank as a cup pack (hard cup). The inner rear wall 33 extends (approximately) over the full height of the package or package contents. The inner front wall 31 is formed in dimensions and design, including the inner side flaps 35, as a conventional in packs of the type folding box collar. This includes a downwardly recessed, transversely directed collar edge 37. Furthermore, the inner side tabs 35 are provided with converging projections 38 which form the transition from the inner front wall 31 to the inner rear wall 33 in the region of the inner side walls 34. Corresponding to the limited by a curved edge projections 38 are opposite the inner side tabs 36 provided at the ends with recesses 62 corresponding to the projections 38 in shape and size. The contour of the collar edge 37 is formed corresponding to the opposite side of the inner rear wall 33, so that the blank for the inner pack 15 completely and without waste from a continuous web of material in the width of the blank according to Fig. 2 can be separated.

The inner package 15 forms the (block-shaped) package contents for the outer package 14 with appropriate matching of the blanks according to Fig. 1 and Fig. 2 , The inner package 15 is fully receptacle in the outer package 14. Furthermore, both packages 14, 15 are connected to each other, via glue joints 39 in the rear packing area, namely between outer rear wall 18 and inner rear wall 33. The glue joints 39 are mounted in an upper, frontal area on the one hand and in a lower, bottom-side area on the other hand. When the package is opened, namely with the partial pack 27 removed, the contents of the pack are free in an upper end and front region for the removal of cigarettes 10 (FIG. Fig. 8 ).

The opening position of the package, namely the spread of the partial packs 27, 28 is limited, by a retaining tab or joint flap 40 as a connecting member between the inner pack 15 and outer pack 14. The tab 40 is on the inner pack 15 in the area the inner front wall 31 attached or part thereof and with the outer front wall 16 connected inside.

In the embodiment according to Fig. 1 to Fig. 10 The hinge flap 40 extends over the full width of the front wall 31 due to a corresponding U-shaped punching with punching legs 41 in the region of a folding or packing edge formed between the inner side tabs 35 on the one hand and the inner front wall 31. The punching legs 41 extend approximately in a central region of the inner front wall 31 and terminate at a distance from the inner bottom wall 32. A transversely directed, arcuate transverse punching 42 extends at a significant distance from the frontal boundary of the inner front wall 31 and the collar edge 37 to form a transverse web 43rd

The joint flap 40 is divided into two sections 46, 47 by two parallel hinge lines 44, 45. The outer end portion 47 is connected to the outer pack 14. Preferably, the portion 47 is fully bonded by gluing to the inside of the outer front wall 16 ( Fig. 7, Fig. 8 ). When opening and closing the package, namely during the pivotal movement of the part pack 27, there is a special effect of the joint flap 40 due to the size and arrangement of the same. At the beginning of the opening movement, the hinge flap 40 is lifted out of a starting position within the inner front wall 31, wherein the sections 46, 47 due to the hinge lines 44, 45 pivot against each other. In a middle position (dash-dotted in Fig. 8 ) receives the free portion 46 due to the geometric conditions an arcuate position, whereby a resilient tension in the hinge flap 40 is constructed. This first acts in the direction of the closed position and overcoming a "dead center" in the opening direction. When this is reached, the section 46 is in an extended position ( Fig. 8 ). During the closing movement, the processes take place in the reverse order.

In order to facilitate the opening process, the outer package 14 is provided in the region of the outer front wall 16 with a preferably circular opening 48. Through this, an actuating force can be transmitted to the inner pack 15 by means of a finger ( Fig. 7, Fig. 8 ). In the region of the opening 48, the inner packing 15, namely its inner front wall 31 can have a printing or graphic design which is attached in the region of a circular contour of the transverse web 43 and is visible from the outside when the packing is closed.

Another peculiarity is a detail of the punching for the joint flap 40. The preferably parallel lateral punching legs 41 extend beyond the transversely directed hinge line 44 (FIG. Fig. 3 ). As a result, the hinge line 44 is free and reliably effective in pivotal movements of the joint flap 40. The hinge lines 44, 45 may be defined by embossing and / or punching.

Furthermore, a special feature in the area of the back of the pack is provided. The outer rear wall 18 has a flap 49 defined by perforation lines. This can extend in the predominant region of the outer rear wall 18, wherein an upright, linear joint 50 for the pivotable flap 49 preferably extends in the region of an upright packing edge on the package back side. The flap 49 cooperates with a graphic design 51 and / or informative printing on the inner rear wall 33 of the inner pack 15. When the flap 49 is opened, the design 51 becomes visible. When reclosing the flap 49, a tongue 52 can be inserted into a slot 53 of the inner rear wall 33.

The embodiment according to Fig. 11 to Fig. 19 is in principle, namely in particular with regard to the arrangement and mode of action of joint plates 54, 55, in analog Way constructed as the embodiment described above. The outer pack 14 is taken over substantially unchanged, wherein the flap 49 is missing in the region of the outer rear wall 18. Incidentally, the blank corresponds to Fig. 1 the outer pack 14 of the embodiment according to Fig. 11 to Fig. 19 ,

Instead of a substantially complete inner packing is in this embodiment, a special inner part 56 according to Fig. 11 provided, which may be referred to as the collar of a folding box due to the design and function, namely collar front wall 57 and collar side flap 58 is made. The thus formed blank is placed on the front of the package contents, namely on the cigarette block 13 (FIG. Fig. 12 ), wherein the collar side tabs 58 abut against side surfaces of the cigarette block 13. The blank of the inner part 56 and the collar side tabs 58 extend to the bottom of the pack, are therefore based on the outer bottom wall 17 when the package is closed. The collar side tabs 58 are provided with corresponding edge-side support projections 59. On the opposite side to the support projections 59 are recesses 62 in the region of the collar side tabs 58 in shape and size of the support projections 59. Also, a transversely directed upper collar edge 63 corresponds to the lower boundary of the collar front wall 57, so that this of a continuous material web can be separated without waste.

In the area of the collar front wall 57, the connecting member with outer packing 14 is attached. There are two adjacent joint plates 54, 55, which are also formed by U-shaped punches - as in the joint flap 40 - which are fixed - as also in the joint flap 40 - with residual compounds 60 within the collar front wall 57. The residual compounds 60 are severed the first time the package is opened. Furthermore, each hinge flap 54, 55 is divided by hinge lines 44, 45 into sections 46, 47. The end-side portions 47 of both joint plates 54, 55 are (by gluing) connected to the inside of the outer front wall 16 ( Fig. 15, Fig. 16 ). The collar side flaps 58 are connected to the outer package 14, namely the back side subpackage 28, in the area of the outer side flaps 23 (by gluing).

Opening and closing process take place in an analogous manner as in the previous embodiment. This also applies to the resilient action of the joint plates 54, 55 or the portion 46. The two joint plates 54, 55 are separated by a preferably central longitudinal ridge 61, which ensures the stability of the relatively small-area inner part 56, especially when opening and closing the package. Another special feature of this blank form, in particular according to Fig. 11 , is that a transverse web 64 adjoining the hinge lines 44 is stabilized by the longitudinal web 61 despite a relatively small width. This makes it possible to produce the blank 56 with a relatively small dimension in the longitudinal direction, ie with a relatively narrow transverse web 64. The sufficient dimensional stability is ensured by the construction described.

In the production of the packs described, it is expedient to proceed in such a way that in a first folding unit, in particular folding turret, the blank of the inner pack 15 is folded around the contents of the pack, that is to say the cigarette block 13, in a manner which is in principle conventional, so that the in Fig. 4 shown unit is created. In a second folding unit, in particular folding turret, then the outer package 14 is attached by folding the blank according to Fig. 1 around the inner pack 15 around. The hinge flap 40 or 54, 55, namely its portion 47, and / or the outer front wall 16 is provided with glue before the outer pack 14 is made. During the folding process, the outer front wall 16 comes into contact with the glue spots of the sections 47 (or vice versa), so that the connection between the hinge flap 40, 54, 55 and the outer pack 14 is made without special measures. The blanks of the packs or pack parts are expediently made of thin cardboard, as usual with folding boxes.
