Abstract

The invention illustrates and describes a blank (1) for producing an external packaging unit, comprising: at least four regions (I, II, III, IV, V, VI) each with a rear wall (2), a base surface (3), which is assigned to the rear wall (2), and at least one inner side surface (4'), which is assigned to the rear wall (2), wherein each rear wall (2) has four sides, wherein each rear wall (2), on one of its sides, is connected, along a folding line (5), to the base surface (3) assigned to it, wherein each rear wall (2), on one of its sides, is connected, along a folding line (5) arranged along a centre axis (7), to a rear wall (2) of an adjacent region (I, II, III, IV,V, VI), wherein each rear wall (2), on at least one of its sides, is connected, along a folding line (5), to the inner side surface (4') assigned to it, and wherein the at least one inner side surface (4') of a region (I, II, III, IV, V, VI) is connected, along a folding line (5), to an inner side surface (4') of an adjacent region (I, II, III, IV, V, VI). The invention additionally illustrates and describes a method for producing an external packaging unit from such a blank (1) and also a packaging system comprising such an external packaging unit. In order to achieve the situation where the external packaging units, which can be made from the blank by folding, can be stacked reliably one upon the other, it is proposed that the inner side surfaces (4') be spaced apart from the centre axis (7), this resulting in an offset (6) between the inner side surfaces (4') and the centre axis (7).

Description

Blank and method for producing an outer packaging

The invention relates to a blank for producing an outer packaging, comprising: at least four regions each having a rear wall, one of

Rear wall associated bottom surface and at least one of the rear wall

associated inner side surface, wherein each rear wall has four sides, wherein each rear wall is connected at one of its sides along a fold line with its associated bottom surface, wherein each rear wall connected at one of its sides along a arranged on a central axis fold line with a rear wall of an adjacent region wherein each backplane is connected along at least one of its sides along a fold line to its associated inner side surface, and wherein the at least one inner side surface of a region is connected along a fold line to an inner side surface of an adjacent region.

The invention also relates to a method for producing an outer packaging from such a blank as well as a packaging system comprising such outer packaging.

Numerous Ümverpackungen are known from the field of packaging technology. Packagings are packaging whose intended contents are other packagings. Packs are therefore also referred to as primary packaging and Ümverpackungen as secondary packaging. An outer packaging according to the invention is particularly suitable as a secondary packaging for beverage cartons made of composite material. Overpacks, for example, have the purpose of combining several packages into units in order to be able to stack them more easily on pallets or the like. Another function of Ümverpackungen lies in it, the packages contained in the outer packaging and their contents

Environmental influences such as shocks, load pick-up or contamination. Finally, outer packaging also facilitates the transport of goods that are typically not purchased separately.

Many outer packaging is made from blanks. Blanks are flat webs that have been cut or punched into a specific shape. The defined shape of the blanks ensures that an outer packaging can be produced from the blanks by means of various folding processes. The shape of the blank therefore determines the shape of the producible from the blank overpack.

A widespread and thus known from the prior art outer packaging is shown in Fig. 7a and Fig. 7b. It is an outer packaging according to FEFCO-ESBO Code 0460 (FEFCO = Federation Europeenne of Fabricants de Carton Ondule - European Association of Corrugated Board Manufacturers, ESBO = European Solid Board Organization). The outer packaging is characterized mainly by a low material requirement and ease of manufacture. A disadvantage, however, is the relatively low carrying capacity of this outer packaging, so that when stacking a plurality of outer packaging almost the entire load has to be carried by the packages standing in the outer packaging.

Another outer packaging for containers is known, for example, from JP 2007-008491 A. The outer packaging is produced from two blanks wherein a lower part is folded from the first blank and wherein an inner part is folded from the second blank. The inner part is then inserted into the lower part. The resulting overpack can accommodate six containers that stand on the base and are held laterally by the inner part in position. The

Top of the inner part and the underside of the lower part are flat, so that several outer packaging, such as on a pallet, can be stacked on top of each other. The outer packaging known from JP 2007-008491 A has several disadvantages. First, the production of the outer packaging is relatively complex, since it consists of several blanks that need to be joined together. Another disadvantage is that due to the flat top and bottom of the

Repackaging the risk that several stacked

Umverpackungen be moved laterally relative to each other, whereby the stack could fall over. In addition, the transport of the outer packaging is difficult. This is because the inner part is only loosely inserted into the lower part, so that the outer packaging can be raised only on the lower part. Consequently, no carrying handle or the like is provided on the inner part. Finally, the outer packages shown have the disadvantage that the containers standing in the outer packaging are concealed in their lower area by a circumferential front wall. This makes it difficult for customers to provide product information on the

To recognize containers without removing them from the outer packaging.

Although such outer packaging is therefore hardly to transport

Presentation of containers suitable.

Another outer packaging is known from US 4,119,202. This intended for receiving two canisters outer packaging can be made easier because it can be folded from a single blank. The one-piece design of the blank also has the advantage that the bottom surfaces of the outer packaging are firmly connected to the side and back surfaces of the outer packaging, so that the outer packaging can be lifted and transported via a handle opening provided in the back surfaces. Several outer packaging can be combined by a plastic film into units.

However, the outer packaging shown in US 4,119,202 also has a flat top and a flat bottom. This has the disadvantage already described above that stacked outer packages are laterally displaceable. Due to the lack of lateral support there is the danger of falling stacks. Another disadvantage is that the outer packaging take only two canisters can. In addition, these outer packages also have circumferential front walls which hide the lower areas of the canisters standing in the outer packaging. These outer packages are therefore intended primarily for transport purposes and hardly suitable for the presentation of the canisters. Finally, another disadvantage is that these outer packages are difficult to machine due to the complicated folds of the bottom area.

The invention is therefore based on the object to design the blank described above and previously explained in such a way and further that the foldable from the blank outer packaging can be safely stacked on each other and are suitable for presentation of the packs contained in the outer packaging.

In a blank according to the preamble of claim 1, this object is achieved in that the inner side surfaces are spaced from the central axis, so that an offset arises between the inner side surfaces and the central axis.

Cuttings according to the invention can theoretically be divided into several areas. Each of these areas includes a back wall, a bottom surface, and at least one interior side surface. Under inner side surfaces become

Side surfaces understood that are connected to other inner side surfaces and are therefore arranged after the folding "inside." In contrast, are external

Side surfaces are connected to no other side surfaces and are therefore arranged after folding on the edge of the outer packaging, ie "outside." The different areas of the blank are delimited by fold lines

Fold lines to facilitate the folding of the blank; They can be realized, for example, by a material weakening, in particular by a perforation or an embossing or creasing of the blank. Through a

The blank according to the invention outer packages can be obtained with very high load capacity, since after folding several vertical walls are double-walled: First, the back walls of one side the blank after folding along the central axis applied to the back walls of the other side of the blank. Second, after the blank has been folded, the inner side surfaces of each region are applied to the inner side surfaces of the adjacent region. In this way, both rear walls and inner side surfaces with double wall thickness are achieved. In particular, the double-walled design of the inner side surfaces increases the carrying capacity of the foldable from the blank outer packaging in the vertical direction, which

For example, the stackability of the outer packaging improved. Overpacks of blanks according to the invention can - especially due to the

double-walled design - compared to standard outer packaging have increased by at least 30%, in particular by at least 40% increased load capacity.

According to the invention arises between the inner side surfaces and the

Central axis an offset. Since the upper edges of the rear walls are arranged on the central axis, an offset also arises between the inner side surfaces and the upper edges of the rear walls. In other words, the inner ones

Side surfaces arranged such that a distance is maintained between the upper edges of the inner side surfaces and the central axis. This can for example take place in that the inner side surfaces are shorter than the rear walls.

The distance between the inner side surfaces and the central axis - ie by the "offset" - ensures that after folding the upper edges of the rear walls extending along the central axis project in a vertical direction beyond the upper edges of the inner side surfaces a

positive connection between several stacked

Umverpackungen be formed. For this purpose, the upper edges of the

Side surfaces of a first - lower - outer packaging a plane to which the

Bottom surfaces of a second - upper - wrapper can be placed. However, since the upper edges of the rear walls protrude beyond this level, the pushed upper edges of the rear walls of the lower outer packaging when stacking between the mutually associated rear walls of the upper outer packaging. Through this process, a positive connection in the manner of a connector is generated between two stacked outer packaging. This has the advantage that the Ümverpackungen can be stacked particularly secure and are particularly secured against lateral slipping.

An inventive blank has in the folded state - ie as outer packaging - a particularly high load capacity in the vertical direction. The high load-bearing capacity has been demonstrated for example by the experiments described below.

For the purposes of this invention, the carrying capacity is determined on the basis of the standard DIN EN ISO 12048 ("ready-to-ship packages, compression and stacking tests using a compression testing machine", December edition)

2000 / April 2001). To determine the load-bearing capacity, the outer packagings are placed between two pressure plates and an increasing load is applied until failure occurs ("compression test" in accordance with points 3a and 7.1 of the above-mentioned standard.) The outer packagings are tested to the extent that they do not conform to the norm the surface of the upper pressure plate is adapted to the offset of the blank according to the invention, so that the force is introduced in particular in the upper edges of the inner side surfaces of the outer packaging, as in the case of a stacking

tested in different dimensions and compared to corresponding standard outer packagings tested in the same way (FEFCO-ESBO code 0460). The tested outer packagings are intended for holding composite beverage cartons. However, during the measurements, the outer packagings are not covered with these - in the following Table 1, "packs"

designated - filled beverage cartons. In accordance with item 7 of the In the case of the above-mentioned outer packaging as well as in the standard outer packaging, measurements with at least five identical ones were identical

Repackaging done. Average values were then calculated from the measurement results

The properties of the overpacks tested and the results of the measurements are shown in Table 1 below:

The results show that the blank in the folded state in the vertical direction has a carrying capacity of at least 1000 N, in particular of at least 1500 N or at least 2000N

Outer packaging of a blank according to the invention on a carrying capacity that is at least 30%, in particular at least 40% greater than a standard outer packaging (FEFCO ESBO Code 0460). The high vertical load capacity is achieved in particular by the double-walled design of the supporting walls or surfaces - especially the inner side surfaces - and improves the

Stackability of the outer packaging.

According to one embodiment of the invention it is provided that the length of the offset is at least 10 mm and in particular in the range of 10 mm to 40 mm The length of the offset corresponds to the depth of the positive connection. at an offset of 30 mm can therefore be pushed up to 30 mm between the rear walls of an upper outer packaging, the upper edges of the rear walls of a lower outer packaging. An offset of between 10mm and 40mm provides an optimal compromise between easy stackability (better with shorter misalignment) and a secure positive connection (better with longer misalignment).

A further embodiment of the invention provides that the blank is formed in one piece. By a one-piece or one-piece blank is the

Making the outer packaging easier. Because the individual surfaces of the blank need only be folded along fold lines and possibly joined together. Unlike an outer packaging, which is made of multiple or multi-part blanks, eliminating the costly assembly of the

different blanks. In addition, only a single magazine for the blanks is required in the production, which improves the machine manufacturability. Another advantage of outer packaging of one-piece blanks lies in increased stability, since in contrast to outer packaging of multiple or multi-part blanks is not to be feared that the assembled blanks fall apart again.

According to a further teaching of the invention it is proposed that the blank is made of paper or cardboard, in particular of corrugated cardboard. Paper, cardboard and corrugated board are characterized by low costs and good suitability for recycling (recycling). Corrugated board is produced by gluing together smooth and corrugated webs of paper and, despite its low density, has a high degree of strength, making corrugated cardboard very light yet robust

Repackaging can be made. The blank may for example be made of corrugated board according to the standard DIN 55468, Part 1, August 2004 issue (there in particular shaft B or shaft E). Corrugated cardboard whose wave and cover papers have a thickness in the range between 100 g / m ² and 140 g / m ² have proven to be particularly advantageous. According to a further embodiment of the invention it is provided that the blank has a thickness in the range of 1 mm to 3 mm. Especially at the

Use of corrugated cardboard blanks have proven with a thickness in this range and are a good compromise between low cost and sufficient rigidity. As corrugated cardboard corrugated type B (wave height 2.2 mm to 3 mm) or E (wave height 1 mm to 1.8 mm) according to the standard DIN 55468, part 1, issue August 2004 proved. A further embodiment of the invention provides that each region of the blank comprises two side surfaces associated with the rear wall. By each rear wall is connected to two side surfaces, it is achieved that also in the outer regions on both sides of the rear wall, a side surface is present. Areas adjacent to another area after folding on either side are also referred to as "inner areas" and have two inner side surfaces, and areas that after folding on only one side are adjacent to another area are also referred to as "inner areas". outer areas "and have only one inner side surface associated with the adjacent area. After this

According to an embodiment of the invention, the "outer regions" also have a second side surface, in particular an outer side surface the outer packaging fixed. The outer side surfaces can

The height of the outer side surfaces may be lower than, equal to or higher than the height of the inner side surfaces. Outer side surfaces with a lower height save material and nevertheless provide the packs with sufficient lateral support. Outer side surfaces with the same height can - especially if they have the same distance from the central axis as the inner side surfaces - serve when stacking several outer packaging as an additional support surface and thus further increase the carrying capacity. Outer

Side surfaces with greater height provide a secure lateral support, in particular when stacking, when the outer side surfaces a smaller offset to

Central axis than the inner side surfaces. The different variants can be combined with each other, so that, for example, two outer

Side surfaces a smaller height and two outer side surfaces may have a greater height than the inner side surfaces.

According to another teaching of the invention it is provided that the rear walls are rectangular, in particular square shaped. Alternatively or additionally, it can be provided that the bottom surfaces are rectangular, in particular square-shaped. Due to the rectangular or square shape is achieved that the

Rear walls and the floor surfaces are limited by straight edges. Straight edges are particularly well suited to the arrangement of fold lines. Both in the back walls and in the bottom surfaces, it is preferred that all rear walls or all

Floor areas have the same size, so that the outer packaging can accommodate several packs of identical size.

According to a further embodiment of the invention, it is proposed that each floor surface is connected exclusively to a rear wall and / or a side surface. The floor areas should be so apart from back walls,

Side surfaces and attached thereto connecting tabs with no other surfaces or walls to be connected. In particular, the floor surfaces should be connected with no front surfaces or front walls, as these have a clear view of the packages contained in the outer packaging and on it

Partially obstruct product information. An outer packaging without front surfaces and front walls thus has the advantage of being suitable not only for transport but also for the presentation of packages. The presentation of the goods can therefore be done directly in the stacked outer packaging; separate shelves or stands are not required. According to another teaching of the invention, it is provided that the inner

Side surfaces are rectangular, in particular square shaped. By the rectangular or square shape is achieved that the inner side surfaces are limited by straight edges, which are particularly well suited for the arrangement of Faitlinien. It is preferred that all inner side surfaces be the same size so that the outer package can accommodate a plurality of identical sized packages.

According to a further embodiment of the invention, it is proposed that the blank in each of the regions has two connecting straps which are connected along fold lines to the side surfaces and / or to the bottom surfaces. Through the connecting straps, the side surfaces can be connected to the Bodenfiächen. For this purpose, the connecting tabs are folded over and form a

Overlap with their assigned areas. A connecting tab which is connected to a side surface thus forms after folding an overlap with its associated bottom surface and a connecting tab which is connected to a bottom surface, forms after folding an overlap with its associated side surface. The region of the overlap can be used for example for the formation of an adhesive bond, whereby the stability of the

Repackaging is increased. According to a further embodiment of the invention, it is proposed that each side face has a connection tab which is connected to the side face along a fait line. By providing the connection tabs on the side faces, material can be saved. Because the breadth of

Connecting tab can be adapted to the width of the side surface.

In particular, the outer side surfaces and their connecting straps may have a smaller width than the inner side surfaces and their

Connecting plates.

Another teaching of the invention provides that at least two of the interconnected rear walls have an opening. Preferably, the openings are arranged in the upper region of the rear walls and symmetrically to the central axis. This has the advantage that cover the two openings after folding the blank along the arranged on the central axis fold line. In this way, the two congruent openings form a penetration, which can be used for example as a carrying handle. The openings can also be used as an intervention for

Machines or tools serve, which facilitates the handling and alignment of the blanks.

The above-described object is also achieved by a method for producing an outer packaging from a blank, in particular from one of the previously described blanks, comprising the following steps: a) folding the blank along the fold lines between the rear walls and the side walls associated with the rear walls, b Folding the blank along the fold lines between the inner side surfaces of one region and the inner side surfaces of an adjacent region, c) folding the blank along the fold lines between the back walls and the bottom surfaces associated with the back walls, d) connecting the folded bottom surfaces to the folded side surfaces, and e) folding the blank along the folding lines arranged on a central axis between the rear wall of one area and the rear wall of the adjacent area.

The inventive method for producing a repackaging is particularly inexpensive and easy to carry out, since the steps a), b), c) and e) can be realized exclusively by folding. Preferably, the blank is folded in steps a), b), c) and e) at the respective locations by 90 ° and 180 °, respectively. In addition to folding, two of the folded surfaces must be joined together in step d). This can be done, for example, that a projection of a surface in a designated recess of the other

Placed surfaces, so that a plug connection is generated. The steps a] to c) can be carried out in any order; however, they are preferably carried out in the order given. The following are the steps d) and e), which can also be carried out in any order, but are preferably carried out in the order given. The folding takes place in steps a), b) and c) such that the side surfaces and the

Floor surfaces - are folded in the same direction - relative to the rear walls.

According to one embodiment of the method, the following step is performed before step d): f) folding the blank along the folding lines between the

Connecting straps and the side surfaces and / or between the

Connecting straps and the floor surfaces. Through the connection tabs, a particularly reliable connection between the folded bottom surfaces and the folded side surfaces can be generated. To this embodiment of

Method is further proposed that after step f), the following step is performed: g) bonding the connecting tabs with the side surfaces and / or the bottom surfaces. By adhesive bonds, a cost-effective and stable connection between the connecting straps and the side or

Floor surfaces can be achieved.

The object described above is finally solved by a

A packaging system comprising: an outer package folded from one of the previously described blanks, at least one package for each region of the blank, and means for securing the packages to / in the outer package. Preferably, each package of the outer package becomes a package

added. An overpack with six areas therefore preferably contains six packs. Alternatively, two packages can be received from each area of the outer packaging, so that an outer packaging with six regions contains twelve packages. In order that the packages do not fall out of the outer packaging, suitable means for attaching the package are provided. The

Packaging system can alternatively also several stacked

In this case, each of the outer packages has at least one package for each area of the blank and means for attaching the packages to / in the outer package. Finally, according to a further embodiment of the invention, it is proposed that the means for fixing the packs is adhesive. Alternatively or additionally, the means for fixing the packs may be a fastening band. By adhesive, a cohesive connection between the packs and the

Be generated overpack, so that the packs are attached cost-effectively and safely to the outer packaging. Preferably, an adhesive is used which leaves no residue or damage to the package when removing the packages from the outer packaging. By one or more

Fastening straps can - depending on the direction - a positive and / or non-positive connection between the packs and the outer packaging are generated. For this purpose, the fastening band spans the entire outer packaging or - preferably - only one half or side of the outer packaging and the therein

arranged packages. By the two straps each only one half or side of the outer packaging with the packages therein

span, the stackability can be improved. Because they are each other

Assigned back panels are not in this configuration by the

In the case of stacking, the above-described "plug-in connection" can therefore be designed particularly simply. [Befestigungs Vorzugsweise] Fixing tapes made of transparent plastic are preferably used, since they are inexpensive and do not hide the view of the front sides of the packages.

The invention will now be described with reference to a preferred one

FIG. 7b shows an outer packaging produced from the blank of FIG. 7a.

Fig. 1 shows a blank 1 according to the invention for producing a

Outer packaging in flat condition. The state shown in Fig. 1 corresponds to the original state of the blank 1 before its folding. The in Fig. 1

Blank 1 illustrated by way of example comprises six areas which are marked with I to VI. Each of these areas I-VI comprises a rectangular back wall 2, a rectangular bottom surface 3 and two side surfaces 4, including at least one inner side surface 4 '. The side surfaces 4 are inner side surfaces 4 'and outer side surfaces 4 "." Two of the outer side surfaces 4 "have a lower height than the inner side surfaces 4'; on the other hand, the other two outer side surfaces 4 "have a greater height than the inner side surfaces 4 'and can therefore serve as side guides, the two outer side surfaces 4" of lesser height and the two outer side surfaces 4 "of greater height are each arranged diagonally opposite one another The rear walls 2, the bottom surfaces 3 and the side surfaces 4 are delimited from each other by fold lines 5.

Each rear wall 2 has four sides. On each of these sides, each rear wall 2 is connected along a fold line 5 with its associated bottom surface 3. On the opposite side of each rear wall 2 with a rear wall 2 of the The rear wall 2 from area I is connected via a folding line to the rear wall 2 from area IV. In the same way, the rear walls 2 from the areas II and V and ΙΪΪ and VI are interconnected. In addition, each rear wall 2 is connected on at least one of its sides via a fold line 5 with a side surface 4. In the case of the blank 1 shown by way of example in FIG. 1, each rear wall 2 has two side surfaces 4. However, the outer side surfaces 4 "are optional, so that the rear walls 2 from the regions I, III, IV and VI could also have only one inner side surface 4 'as an alternative to the embodiment shown in Figure 1. In addition, as shown in FIG 1 - possible that outer side surfaces 4 "are present, that one or more of these outer

However, the rear walls 2 from the areas II and V must necessarily have two (inner) side surfaces 4 'in order to be able to establish a connection to both adjacent areas from area II represents via inner

Side surfaces 4 'a connection to the rear walls 2 from the areas I and III ago. In the same way, the rear wall 2 from the area V via inner

Side surfaces 4 'a connection to the rear walls 2 from the areas IV and VI ago. Thus, at least one side surface 4 of each region is connected via a fold line 5 to a side surface 4 of an adjacent region. The regions II and V are also referred to as "inner regions", while the regions I, III, IV and VI are also referred to as "outer regions".

In the blank 1 exemplified in FIG. 1, the two long sides of the rear walls 2 are longer than each of the sides of the inner side surfaces 4 '. This has the consequence that an offset 6 is formed between the rear walls 2 and the inner side surfaces 4 '. In the embodiment shown in Fig. 1, the offset 6 forms on a central axis 7, which divides the blank 1 in two sides and the areas I, II, III delimits the areas IV, V, VI. The offset 6 has the effect that the rear walls 2 protrude at a folding of the blank about the central axis 7 on the inner side surfaces 4 '. This has the consequence that several blanks 1 in the folded state formschiüssig can be stacked on each other, as below in the

Connection with Fig. 3 will be explained in more detail.

The blank 1 shown by way of example in FIG. 1 also has connection tabs 8. The connecting straps 8 are connected by fold lines 5 with the side surfaces 4 and are intended to serve the side surfaces 4 after the folding of the

Blank 1, about bonded joints to connect to the bottom surfaces 3. Deviating from the embodiment shown in Fig. 1, the

Connecting tabs 8 also be connected via fold lines with the bottom surfaces 3, to connect in a corresponding manner with the side surfaces 4. Furthermore, the blank 1 exemplified in Fig. 1 has openings 9, on. The openings may be gripping openings for carrying the outer packaging produced from the blanks 1. The openings 9 are provided in the rear walls 2, in particular cut out of the rear walls 2 or

stamped out.

In Fig. 2, the blank 1 of Fig. 1 is shown in the partially folded state. The bottom surfaces 3, the side surfaces 4 ', 4 "and the connecting straps 8 were each folded by about 90 ° along the fold lines 5. In addition, the connecting straps 8 were bonded to the bottom surfaces 3. Along the central axis 7, however, the blank 1 was inserted at the in Fig. 2 shown not yet folded, so that the

Rear walls 2 from all six areas I to Vi are still arranged in one plane. It can already be seen in FIG. 2 that the folding of the blank 1 in each of the six regions I to VI has created a chamber which can serve to receive one or two packs.

Fig. 3 shows the blank 1 of Fig. 1 in the fully folded state. The essential difference from the configuration shown in Fig. 2 is that the blank 1 has been folded in Fig. 3 along the center line 7 by about 180 °. As a result, the rear walls 2 from the areas I, II and III touch the rear walls 2 from the areas IV, V and VI and in particular with these are arranged congruently. In addition, the openings 9 are arranged symmetrically to the central axis 7 in the rear walls 2, so that after the folding a

Penetration by two congruent successively arranged openings 9 is possible.

In Fig. 4, the blank 1 of FIG. 2 with packs 10 and two fastening straps 11 is shown. The packs 10 are for example

Beverage cartons of composite material with a spout. In each of the six areas I to VI is a pack 10 in the blank 1. The packs 10 are bounded by a rear wall 2, a bottom surface 3 and two side surfaces 4 and held in position. In order to fix the packs 10, two transparent straps 11 are wrapped or stretched around the blank 1 and the packs 10. In the blank 1 shown by way of example in FIG. 4, a fastening band 11 is wound around the packs 10 of the regions I, II and III; another fastening band 11 is wound around the packs 10 of the areas IV, V and VI. The fastening straps 11 are wound in such a way that they enclose both the packs 10 and the blank 1.

Fig. 5 shows the blank 1 of Fig. 3 with packs 10 and two

Fixing straps 11. The essential difference from the configuration shown in Fig. 4 is again that the blank 1 has been folded in Fig. 5 along the center line 7 by about 180 °. This has the consequence that the rear walls 2 from the areas I , II and III touch the rear walls 2 from the areas IV, V and VI and are arranged in particular congruent with these. In addition, the openings 9 are arranged symmetrically to the central axis 7 in the rear walls 2, so that after folding a penetration through each 2 congruent successively arranged openings 9 is possible.

In FIG. 6, a plurality of blanks 1 stacked on one another are shown in the fully folded state, that is to say as outer packagings. The stack comprises five blanks 1, of which the upper four blanks 1 are filled with packs 10. The packs 10 are held in the blanks 1 with transparent fastening straps 11. The combination of outer packaging, packages and fasteners is also referred to as a packaging system. By contrast, the lowermost blank 1 is not filled with packages, so that the rear walls 2, the bottom surfaces 3 and the side surfaces 4 ', 4 "of this blank 1 can be seen

Configuration, the high load capacity of the blanks 1 is clear: the lowest blank 1, even in the unfilled state, the mass of four completely filled with packs 10 blanks 1 carry. The stability of such a stack is therefore ensured even when the packages 10 are first removed from the lower outer packaging.

The blank 12 comprises a centrally arranged bottom surface 13. The bottom surface 13 is connected to four side surfaces 14, which are two high side surfaces 14 and two low side surfaces 14 ". The high side surfaces 14" are each two

Connecting tabs 15 connected. The bottom surface 13, the side surfaces 14 and the connecting plates 15 are delimited from each other by fold lines 16. FIG. 7b shows an outer packaging 12 'produced from the blank 12 from FIG. 7a. First of all, the four side surfaces 14 were folded upwards by 90 ° along the fold lines 16 for this purpose. Subsequently, the connecting straps 15 were also folded by 90 ° along the fold lines 16, so that the connecting straps 15 form overlaps 17 with the low side surfaces 14 "

Overlaps 17, the low side surfaces 14 "are connected, in particular adhesively bonded, to the connecting straps 15. As an alternative to this sequence, initially only the two high side surfaces 14 ', then the two

Connecting tabs 15 and only finally the two low side surfaces 14 "are folded over, so that in the region of the overlap 17, the low

Side surfaces 14 "lie outside. The blank 12 shown in Fig. 7a and the overwrap 12 'shown in Fig. 7b are manufactured according to FEFCO-ESBO code 0460 (FEFCO = Federation Europeenne of the Fabricants de Carton Ondule - European Association of Corrugated Board Manufacturers; ESBO = European Solid Board Organization - European Organization for

Cardboard).
