DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a package for a group of articles, and more particularly to a three-dimensional packaging container with a paper, foil or thin cardboard outer packaging for a group of tobacco packets. The invention furthermore relates to an apparatus for preparing a blank for such a package, that is to say an apparatus for forming a line of weakening, in particular a perforated line, in the blank for the outer packaging of the package.

[0002]

BACKGROUND OF THE INVENTION The most important field of application of the present invention is packaging containers for cigarettes-so-called tobacco cartons. There is a large package of cigarette packets. The plurality of packets are usually arranged in a row. The most widely used cigarette packaging type consists of 10 cigarette packets subdivided into two rows. One row of cigarette packets has, at its front or back, facing the adjacent row of cigarettes. Package contents, ie
The package contents thus grouped together or in a different arrangement are foldable packages that are exclusively paper or thin cardboard in the case of tobacco packaging containers. It is held by an outer wrapper made from the material.

[0003] Opening a packaging container of this kind,
Improvements are needed to utilize the contents of the package. This can occur when a retailer wants to remove individual cigarette packets from the container, rather than opening the tobacco packaging container by the end consumer, or when the entire contents of the container are to be inserted into a vending machine. Sometimes it is especially true.

[0004]

The underlying object of the present invention is, therefore, to provide a package of the type mentioned at the outset with opening aids which, when used, make it easier to use the packaging container. To provide. The underlying object of the present invention is, in addition, to propose a suitable device for mechanically attaching the opening aid to the package.

[0005]

When this object is achieved, the package is characterized by a line of weakness, in particular a perforation row provided at least in the area of one wall of the outer wrap.

The cigarette containers provided with the arrangement of the individual cigarette packets mentioned at the outset are provided with lines of weakening or perforations in the area of the separating plane between adjacent rows of tobacco packets. . In a packaging container comprising two rows of cigarette packets facing one another, the perforated rows according to the invention extend in the area of the long side walls of the outer wrapping material, approximately in the longitudinal center thereof.

With this line of weakening or perforation line, all of the contents in the package can be removed very easily and quickly. The perforation row can be broken down over its entire length by the intervention of a simple manual operation. In this way, the entire tobacco contents of the package, that is, the (ten) cigarette packets are exposed for removal. These contents can be removed without further breaking the outer packaging.

The device according to the invention is set such that the blank for the outer wrapping material is provided with the said line of weakening or perforation row in a precise position before the folding step, especially in the area of the continuous material web where the blank is produced. You. For this purpose, the device can be moved back and forth across the longitudinal extension of the material web, such that the perforation line is used during the outer packaging to be performed later, at the side of the outer packaging material. A perforating member is provided for providing a perforation row over a partial area of the center of the material web, so as to be provided only on the wall. The piercing member is a piercing disc having a piercing blade along the periphery. During the application of the perforation row, the blank or material web rests on the base.

[0009] Further details of the invention are explained more fully below with the aid of embodiments through the illustration of packages and devices.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the package and apparatus used in connection with the manufacture of the package illustrated and shown in the drawings relates to a packaging container for a group of cigarette packets 10. FIG. This type of packaging is also referred to in practice as a cigarette carton. A plurality of tobacco packets 10, in this case ten, are formed in a regular group and are surrounded by one outer wrapping material 11. The outer wrap 11 is advantageously made of (laminated) paper, but can also be manufactured from other suitable wraps.

[0011] The package unit produced on the basis of the outer packaging material here is an elongated three-dimensional structure. This geometric shape is caused by the arrangement of the tobacco packets 10 in two rows 12, 13 of packets. Each of the two columns 12, 13 of packets consists of the same number of tobacco packets 10, in this case five tobacco packets 10. 2
The tobacco packets 10 of the two packet trains 12, 13 have their large faces adjoining each other, ie their front and rear faces. In the area of the longitudinal center plane of the package unit, a continuous cutting surface 14 occurs between the two packet trains 12,13.

A group of cigarette packets 10 is completely surrounded by an outer wrap 11. The outer packaging material 11
Thus, it comprises a front wall 15, elongated side walls 17 and 18, between which a rear wall 16 opposite to the front wall, and end walls 19 and 20 also facing each other. . The front wall 15 and the adjacent side wall 18 are connected to each other by an edge strip 21. This edge strip is connected to the inside of the front wall 15 by gluing.

The end wall comprises a plurality of folded flaps, namely a trapezoidal inner flap 22, and also trapezoidal side flaps 23, 24 and an upper flap 25. The upper flap 25 is rectangular and completely surrounds the end walls 19, 20 as an outer flap. For this purpose, the upper flap 25 is separated from the adjacent side flap 23 by a perforated line 26.

A special feature of the present packaging container lies in the fact that in one area of the package wall, in this case in the area of the elongated side wall 17, the opening aid is mounted. This opening assisting means is a weakening line that can be easily broken,
Here, it is the perforation row 27 of the outer packaging material 11. Perforated row 2
7 is a substantially center point of the side wall 17, that is, (virtual)
Extends along the longitudinal centerline. In this case, perforation row 2
It is important that the vehicle 7 travels approximately as an opening aid in at least the area of the cut surface 14 between some groups of tobacco packets 10. Thus, when the perforation row 27 is broken, that is, when the outer packaging material is opened, all the package contents, that is, the tobacco packet 10 can be directly taken out. Perforation row 27 (by manual operation)
The process of opening or breaking is facilitated because the perforation row 27 is in this position. The perforation row, in the present embodiment, actually extends over the entire length of the side wall 17 and ends at a small distance from the upright edge 28 of the package. The perforation row 27 is provided mechanically in the process of manufacturing the packaging container. In the case of the present embodiment, the perforation row 27 comprises a material web 2 for which a blank for the outer packaging 11 is to be manufactured.
9 has already been assigned.

For this purpose, a material web 29 is drawn from a reel (not shown) and guided through a perforating unit 30 (see FIG. 3). Thereafter, the blank with the perforated rows 27 is removed by the cutting unit 31 into the material web 29.
Disconnected from The blank is then further processed in a conventional manner in a packaging machine to form an outer packaging material 11.

In front of the perforating unit 30, a material web 2 is provided.
A pendulum, known in principle, is provided which has a fixed deflecting roller for 9 and a movable deflecting roller (both indicated by reference numeral 33). Depending on the relative position of the pendulum 32, if the tension exceeds the critical web tension or if the tension does not reach the critical web tension, the tension of the material web is maintained until the perforating unit is deenergized. Or compensate for tension fluctuations.

The material web 29 is turned in the area of the perforating unit 30 via a stationary guide roller 34 into a horizontal plane. A similar fixed counter roller 35 cooperates with this guide roller 34. This web of material is transported between guide rollers 34 and counter rollers 35 to form a horizontal section 36 of the web (see FIG. 5).

In the area of the web section 36, approximately in the middle of the transverse width, the perforation row extends across the longitudinal extension of the material web 29 so that the width and position of the perforation row 27 coincide. Granted. The perforation row 27 is formed by a perforation member moving back and forth across the material web 29.
It is applied while the material web 29 transferred for each phase is temporarily stationary. A piercing row 27 is created for each movement cycle of the piercing member.

In the present embodiment, the piercing member is a rotating piercing disk 37. The disk is mounted on a shaft 38 connected to a drive wheel or gear 39. Perforation consisting of disc 37, shaft 38, gear 39 and other components This unit is moved across a web of material 29 to create a perforation row 27. Gear 3
9, here, while the gear 39 makes a transverse movement,
The perforated disc 37 runs under a fixed transverse rack 40 so as to perform a precise rotation. In the present embodiment, the size is such that the diameter of the perforated disc 37 is
Or the diameter of the rotating member. Thus, the perforated disc 37 and the gear 39 perform exactly the same rotational movement.

The perforated disk 37 and the gear 39 are provided with a fixed pressurizing cylinder 4 extending in the moving direction of the above-mentioned members.
1 can move. In this case, this is a pressurized cylinder 41 without a piston rod (FIG. 4). The drive member 42 (FIG. 5) is located on the side of the pressurizing cylinder 41 outside the housing, and is connected to a unit that can move back and forth. The pressing force acts on the pressure cylinder 41 or the piston in both directions. A piston (not shown) connects with the drive member 42.

The perforated disc 37 and the gear 39 are connected via a shaft 38 to a carrier 43 whose upper part is formed as a slide 44. The slide 44 slides along a long rail 45 that is partially fixed to the lower side of the pressure cylinder 41. The connecting piece 46 is connected on the one hand to the drive member 42 of the pressure cylinder 41 and on the other hand to the movable unit or carrier 43 or slide 44. The longitudinal movement of the drive member 42 is thus transmitted to the carrier 43. The rotating shaft 38 is provided with a roller bearing 47 inside the carrier 43.
Is held within.

The perforated disk 37 is provided with a perforated blade 48 protruding in a tooth shape on an outer peripheral portion thereof, and a gap or a cut is formed therebetween. Each perforation blade 48 provides one notch in the perforation row in the material web 29.

The perforated disk 37 is sized and structured such that a complete perforation row is created for each movement cycle, ie, one revolution. The effective outer perimeter of the perforated disc 37 is limited with respect to the arrangement of the perforated blades 48 so that this perforated row maintains the correct length. In the current embodiment illustrated, a portion of the perforated disc 37 is missing. Transverse limit edges 49 are the two ends of the cutout of the perforated disc 37 which create the perforation row. The perforation blade 48 is therefore provided along the entire circular outer periphery except for the notch, that is, from one end of the limit edge 49 to the other end. The perforation row 27 is thus precisely defined by the predetermined length of the circular outer periphery comprising the perforation blade, independent of the length of the path in which the perforation disc 37 rotates.

The effective length of the outer periphery of the perforated disc 37 is equal to the length 50 of the perforated row 27 of the material web 29. It is significant that the width 51 is larger than this. The movement path of the perforated disc 37 or the shaft 38 is the width 51 of the material web 29.
(Fig. 4). The relevant end positions of the perforated disc 37 are here selected such that the material web 29 can be moved without damaging at the end positions of the perforated disc 37 when the perforated disc 37 is momentarily stationary. You. In the embodiment disclosed herein by way of example, the marginal edge 49 is aligned parallel to the material web 29 with a clear gap from the material web 29.

While the perforation row 27 is being applied, the material web 29 is held on or against a flat support member. Here, it is a horizontal strip-like holding plate 53. A portion 36 of the web faces the holding plate and contacts the lower portion thereof. In the active area of the perforated disc 37 or the perforated blade 48, the holding plate 53 is provided with a narrow groove 54 extending in its longitudinal direction.

In the area of the perforation unit 30 the perforation row 2
After passing through the counter roller 35, the material web 29 provided with 7 is guided around the adjusting roller 55. The adjusting roller 55 is provided so as to be able to move in the transverse axis, for example in an elongated hole (FIG. 3). The relative position of the adjusting roller 55 is set so as to be adapted to the length of the blank for the outer packaging material to be manufactured even if the length of the blank varies according to the size of the packaging container.

After the adjusting roller 55, the material web 29 is guided around a plurality of further rollers. These rollers are a set of brake rollers 56,
57. Since these brake rollers have a freewheel acting on one side, they can only rotate in one direction. These brake rollers 56,
57 prevents the material web 29 from running backward when the blank for the outer wrapping material 11 is cut from the material web.

The material web 29 is provided with a brake roller 57.
To form an upright web portion 58. A cutting unit 31 is provided in this area. It consists of a cutting blade 59 and a fixed counter blade 60 which are movable in the transverse direction. The movable cutting blade is connected to a biasing mechanism 61 that causes the cutting blade 59 to move back and forth to perform cutting.

The preliminary rollers 62 and 63 are used for the cutting unit 3
1 or provided in front of the blades 59 and 60. These rollers pull the material web 29 forward so as to be exactly equal to the length of the blank for the outer wrapping material 11. The backup rollers 62, 63 can be controlled by a print mark reader (not shown) which functions with the aid of the print marks on the material web 29.

The drilling unit 30 and the cutting unit 31
The length of the blank of the outer wrap 11 including the distance from the edge of another blank to the perforation row 27, and if necessary, is fixedly provided at a precise spacing equal to a plurality of lengths. The problem is that the cutting for the outer wrapping material 11 is performed at a precise distance from the perforation row, so that the perforation row is placed in the area of the finished package at the already described position in the area of the package. is there.
