Description

  The present invention is a blank for manufacturing an exterior box having at least four surface areas, each surface area being assigned to a rear wall, a bottom surface assigned to the rear wall, and a rear wall. Each rear wall has four sides, and each rear wall has a fold line along a fold line on a bottom surface assigned to the rear wall at one of the four sides. And each rear wall is connected to the rear wall of the adjacent area along a fold line located at the central axis at one of its four sides, and each rear wall has its four sides At least one of the inner surfaces assigned to the rear wall along the fold line, and at least one inner side surface of the one surface area is connected to the inner side surface of the adjacent surface area along the fold line. About the blank.

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

  Various exterior boxes are known from the field of packaging technology. The term outer box refers to a package whose intended contents consist of other individual boxes. Therefore, the individual packaging box is also called primary packaging, and the outer packaging box is also called secondary packaging. The outer box of the present invention is particularly suitable as a secondary package for a beverage carton made of composite material. The purpose of the outer box is, for example, to make it easy to stack several individual boxes into a unit by combining them into a unit. Another function of the outer box is to protect the individual box and its contents contained therein from environmental influences such as impact, load or dust. Also, the outer box simplifies the transportation of commodities that are not generally purchased individually.

  Many exterior boxes are made from blanks. A blank is a flat strip of material cut or punched into a specific shape. The prescribed shape of the blank allows the production of the outer box from the blank by various folding operations. Therefore, the shape of the blank defines the shape of the outer box manufactured from the blank.

  A widely used outer box known from the prior art is shown in FIGS. 7a and 7b. These figures are the FEFCO-ESBO Regulation 0460 (FEFCO (European Corrugated Union) = Federation Europeenne des Fabricants de Carton Ondule-Europaeische Vereinigung der Wellpappehersteller; A compliant outer box is shown. This outer box is mainly characterized in that it requires less material and can be easily manufactured. One drawback, however, is that these outer boxes have a relatively low load carrying capacity, so it is necessary for the individual packaging box standing in the outer box to support almost all the loads of several stacked outer boxes. I know that there is.

  Another outer box for a plurality of containers is known from e.g. The outer box is made from two blanks, the first blank being folded into the lower part and the second blank being folded into the inner part. Thereafter, the inner part is inserted into the lower part. The outer box thus manufactured can accommodate six containers. These containers stand on the lower part and are held in place from the side by the inner part. The upper surface of the inner part and the lower surface of the lower part are flat so that several outer boxes can be stacked, for example on pallets.

  The outer box known from US Pat. First of all, the production of the outer box is relatively complicated because it consists of several blanks that need to be assembled. Another disadvantage has been found in the fact that the upper and lower sides are flat, so that several stacked boxes are at risk of laterally shifting from each other and collapsing. Moreover, the transportation of the outer box is relatively complicated. It can be seen that the reason why the transportation is complicated is that the inner portion is only loosely inserted into the lower portion, and therefore the outer box can only be lifted while being placed on the lower portion. Therefore, a transport handle or the like is not provided on the inner portion. The exterior box shown further has the disadvantage that the lower region of the container standing inside it is covered by the front wall of the peripheral wall. This makes it difficult for the customer to read the product information of the container unless the container is removed from the outer box. Thus, this type of outer box is certainly suitable for transporting multiple containers, but is hardly suitable for its presentation.

  Another outer box is known from US Pat. This outer box is designed to accommodate two cans and can be folded from only one blank, so it can be made more easily. The integrated design of this blank also has the advantage that it can be lifted and carried by a handle opening provided on the back surface, since the bottom surface of the outer box is firmly connected to the side surface and the back surface. Several exterior boxes can be combined into a unit by means of plastic film.

  However, the exterior box disclosed in Patent Document 2 also has a flat upper side and a flat lower surface. This has the above-mentioned disadvantage that a plurality of stacked outer boxes can be displaced laterally. Therefore, the stacking may collapse due to lack of lateral stability. It can be seen that another disadvantage is that the outer box can only accommodate two cans. Moreover, these exterior boxes are also provided with the surrounding wall front wall part which covers the lower side area | region of the can standing in it. Therefore, these exterior boxes are mainly for transportation and are hardly suitable for presenting cans. A further disadvantage is that the folding of the bottom surface area is complicated and it is relatively difficult to mechanize the production of these outer boxes.

JP 2007-008491 A U.S. Pat. No. 4,119,202

  Therefore, the present invention is of the kind mentioned above at the beginning so that a plurality of outer boxes folded from a blank can be safely stacked, and further suitable for presentation of an individual box housed in the outer box. Based on the purpose of designing and strengthening blanks.

  In the blank according to the premise of claim 1, this object is achieved by separating the inner side from the central axis such that an offset occurs between the inner side and the central axis.

  The blank of the present invention can be conceptually divided into several areas. Each of these surface areas comprises a rear wall, a bottom surface, and at least one inner side surface. The inner side surface is a side surface connected to the other inner side surface, and thus is a side surface disposed “inside” after the bending operation. On the other hand, the outer side surface is a side surface that is not connected to any other side surface, and is therefore disposed at the edge of the outer box, that is, “outside” after the bending operation. The various areas of the blank are separated from each other by fold lines. The fold line is intended to simplify the folding of the blank and can be realized, for example, in a form that reduces the material of the blank, in particular in the form of drilling or pressing or grooving. The blank of the present invention enables the production of an exterior box with particularly high load bearing capacity. The reason is that several walls extending vertically after the bending operation are realized in the form of double walls. For one, after the folding operation along the central axis, the rear wall on one side of the blank is placed in contact with the rear wall on the other side of the blank. Another reason is that after the blank is bent, the inner side surface of each surface area is disposed in contact with the inner side surface of the adjacent surface area. Thereby, the rear wall and the inner side surface are realized with double wall thickness. The load carrying capacity of the outer box made from this blank is increased in the vertical direction, especially by the double wall design on the inner side surface, so that, for example, the stackability of the outer box is improved. The load carrying capacity of the outer box made from the blank according to the invention is at least 30% higher, in particular at least 40% higher than the standard outer box, mainly due to the double wall design.

  According to the present invention, there is an offset between the inner side surface and the central axis. Since the upper edge of the rear wall is disposed on the central axis, an offset also occurs between the inner side surface and the upper edge of the rear wall. In other words, the inner side surface is arranged such that the upper edge of the inner side surface and the central axis are separated from each other. This can be achieved, for example, by making the inner side surface shorter than the rear wall.

  Due to the distance between the inner side and the central axis, or "offset", the upper edge of each rear wall extending along the central axis protrudes vertically above the upper edge of the inner side after bending. . Thereby, push-in connection can be realized between several stacked outer boxes. For this purpose, the upper edge of each side of the first, ie lower, outer box forms a second, ie upper, plane on which the bottom of the outer box can be placed. However, since the upper edge of each rear wall protrudes above this plane, during stacking operations, the upper edge of each rear wall of the lower outer box is the back wall of the upper outer box. It is pushed in between. This provides a push-in connection similar to a plug-in connection between the two stacked outer boxes. This has the advantage that a plurality of outer boxes can be safely stacked and fixed so as not to be displaced in the lateral direction.

  The blank of the present invention has a particularly high load bearing capacity in the vertical direction in a folded state, that is, in the form of an outer box. This high load carrying capacity was verified by, for example, the following test.

  In the context of the present invention, the standard DIN EN ISO 12048 ("Packaging-Packing Cargo Test Method-Compression and Stacking Test Using a Compression Tester" Ver. 2000 / December 2000 / Load-bearing capacity is required according to the April 2001 edition). In order to obtain the load bearing capacity, each outer box is placed between two pressure plates, and the applied load is increased until a defect occurs (according to paragraphs 3a and 7.1 of the above standard). Compression test "). In this regard, each outer box, unlike the standard, is tested without content. Also, like the stacking arrangement, the surface of the upper pressure plate is adapted to the offset of the blank of the present invention so that a force is introduced, particularly at the upper edge of each inner side of the outer box.

  Multiple outer boxes of the present invention, each with different dimensions, were tested in three series of tests and compared to corresponding standard outer boxes tested in the same manner (FEFCO-ESBO Code 0460). Each outer box tested is for containing a beverage carton made of composite material. However, during the measurement, each outer carton is not filled with these beverage cartons. These beverage cartons are referred to as “individual boxes” in Table 1 below. Measurements were performed according to Section 7 of the cited standard for at least five identical outer boxes of the present invention, as well as for at least five standard outer boxes. Thereafter, the average value of the measurement results was calculated.

  Table 1 below shows the properties and measurement results of the tested outer box.

  These results show that the blank has a load bearing capacity of at least 1000 N, particularly at least 1500 N, or at least 2000 N in the vertical direction when folded. Also, the load carrying capacity of an outer box made from the blank of the present invention is at least 30% higher, in particular at least 40% higher than a standard outer box (FEFCO-ESBO convention 0460). High load carrying capacity in the vertical direction is realized in particular by the double wall design of the support wall or support surface, mainly the inner side surface, and improves the stackability of the outer box.

  According to an embodiment of the invention, it is proposed that the length of the offset reaches at least 10 mm, in particular in the range between 10 mm and 40 mm. The length of the offset corresponds to the depth of the push-in connection. Therefore, when the offset is 30 mm, the upper edge of the rear wall of the lower outer box can be pushed into the rear wall of the upper outer box by a maximum of 30 mm. An offset in the range between 10 mm and 40 mm represents an optimal compromise between ease of stacking (easier with shorter offset) and reliable push-in connection (longer offset is more reliable) .

  According to another embodiment of the invention, it is proposed that the blank is realized in one piece. In the case of a one-piece or one-piece blank, the production of the outer box is simplified. In this case, it is only necessary to bend the individual surfaces of the blank along the fold line and, if applicable, further connect to each other. Unlike exterior boxes made from several blanks or multi-piece blanks, the complicated assembly of various blanks is not required. Furthermore, since only one blank magazine is required during production, the efficiency of mechanized production is improved. Another advantage of an outer box made from a single piece of blank is that it improves stability because there is no risk of falling apart as in the case of outer boxes made from several blanks or multi-piece blanks. I understand that there is.

According to another characteristic of the invention, it is proposed that the blank is made of paper or cardboard, in particular made of cardboard. Paper, cardboard, and corrugated cardboard are inexpensive and suitable for repeated use (recycling). Since the corrugated cardboard is manufactured by laminating a smooth paper web and a corrugated paper web, it has a high strength despite its low density. Therefore, it is possible to manufacture a very lightweight yet robust outer box from cardboard. The blank can be produced, for example, from corrugated board (especially corrugated B or corrugated E) according to standard DIN 55468, Part 1, August 2004 edition. Particularly advantageous is the use of corrugated paper in which the basis weight of the corrugated paper and cover paper is in the range between 100 g / m ² and 140 g / m ²

  According to another embodiment of the invention, it is proposed that the thickness of the blank is in the range between 1 mm and 3 mm. Blanks with a thickness in this range are advantageous, especially when using corrugated cardboard, and have proven to be a good compromise between low cost and sufficient stiffness. The use of corrugated cardboard of corrugated B (wave height of 2.2 mm to 3 mm) or E (wave height of 1 mm to 1.8 mm) according to standard DIN 55468, Part 1, August 2004 edition is particularly advantageous It is.

  According to another embodiment of the invention, it is proposed that each area of the blank comprises two sides assigned to the rear wall. Since each rear wall is connected to two side surfaces, side surfaces are provided on both sides of the rear wall even in the outer surface area. A surface area adjacent to another surface area on both sides thereof after the bending operation is also referred to as an “inner surface area” and comprises two inner side surfaces. A surface area adjacent to another surface area only on one side thereof after the bending operation is also referred to as an “outer surface area” and comprises only one inner side surface assigned to the adjacent surface area. According to this embodiment of the invention, it is proposed that the “outer surface area” further comprises a second side surface, in particular an outer side surface. After the bending operation, an outer side wall is created from these outer side surfaces. Since the “outer surface area” is also provided with a plurality of side surfaces, the individual packaging box is securely fixed in the outer packaging box. These outer sides can each be realized with different lengths. The length of the outer side can be lower or higher than the length of the inner side or equal to the length of the inner side. The outer side has a lower height, which saves material, but still provides sufficient lateral stability for the packaging. The outer side with a length equal to the length of the inner side serves as a further support surface for stacking several exterior boxes, especially if these outer sides are separated from the central axis by the same distance as the inner side As a result, the load bearing capacity can be further increased. An outer side having a height higher than that of the inner side provides reliable lateral stability for stacking several exterior boxes, especially when the offset from the central axis of the outer side is smaller than the inner side. Various variations can be combined with each other, for example, the length of the two outer sides can be lower than the inner side, and the length of the two outer sides can be higher than the inner side.

  According to another characteristic of the invention, it is proposed that the shape of the rear wall is rectangular, in particular square. Alternatively or additionally, the shape of the bottom surface can be rectangular, in particular square. Depending on the rectangular or square shape, each rear wall and each bottom surface is defined by a plurality of straight edges. Straight edges are particularly suitable for the placement of fold lines. Regarding the rear wall and the bottom surface, it is preferable that the sizes of all the rear walls and all the bottom surfaces are the same so that the outer packaging box can accommodate several individual-sized packaging boxes.

  According to another embodiment of the invention, it is proposed that each bottom surface is connected to only one rear wall and / or one side. Thus, it is not necessary to connect each bottom surface to any other surface or wall apart from the rear wall, side surfaces and connecting straps secured thereto. In particular, the bottom surface should not be connected to any front or front wall. The reason is that the individual packaging box accommodated in the exterior box and the product information described therein are partially invisible. Therefore, the exterior box having no front surface and front wall has an advantage that it is suitable not only for transportation but also for presentation of an individual packaging box. Therefore, it is possible to directly present a product with a plurality of outer boxes stacked, and a separate shelf or rack is not required.

  According to another characteristic of the invention, it is proposed that the shape of the inner side is rectangular, in particular square. Due to the rectangular or square shape, the inner side is defined by straight edges that are particularly suitable for the placement of the fold lines. It is preferable that all the inner side surfaces are the same size so that the outer box can accommodate several individual packaging boxes of the same size.

  According to another embodiment of the invention, it is proposed that the blank comprises two connecting straps in each area. These straps are connected to the side and / or bottom along a fold line. The side straps can be connected to the bottom by connecting straps. For this purpose, the connecting strap is folded so as to form an overlap with the surface assigned to it. Therefore, the connecting strap connected to the side surface forms an overlap with the bottom surface assigned to it after the bending operation, and the connecting strap connected to the bottom surface overlaps with the side surface assigned to it after the bending operation. Form. The overlapping area can be used, for example, to provide an adhesive connection that increases the stability of the outer box.

  According to another embodiment of the invention, it is proposed that each side comprises a connecting strap connected to the side along a fold line. By providing the connecting strap on the side, material can be saved. In this case, the width of the connecting strap can be adapted to the width of the side surface. The outer side surface and its connecting strap may in particular have a narrower width than the inner side surface and its connecting strap.

  According to another characteristic of the invention, it is proposed that at least two of the interconnected rear walls comprise openings. These openings are preferably arranged symmetrically with respect to the central axis in the upper region of the rear wall. This provides the advantage that both openings overlap after the blank is folded along a fold line located at the central axis. Thus, the two openings that are back to back form a passage that can be used, for example, as a carrying handle. These openings can also help with machine or tool engagement, simplifying blank alignment and handling.

  The above object is also achieved by a method for producing an outer box from a blank, in particular the blank. The method comprises the steps of a) folding the blank along a fold line between each rear wall and the side assigned to each rear wall; and b) the inner side of one area and the inner side of an adjacent area. Folding the blank along a fold line between: c) folding the blank along a fold line between each rear wall and the bottom surface assigned to each rear wall; and d) each folded bottom surface. Connecting each of the folded sides to the folded side; and e) folding the blank along a fold line between the rear wall of one area and the rear wall of the adjacent area located at the central axis. including. The method according to the invention for producing the outer box is easy and can be carried out with no particular costs, since steps a), b), c) and e) are simply folding operations. In steps a), b), c) and e), the blank is preferably folded at 90 ° and 180 °, respectively, at the corresponding position. In addition to these folding operations, two of the folded surfaces need to be connected to each other in step d). This can be achieved, for example, by inserting a protrusion on one surface into an assigned recess on the other surface so as to provide a plug-in connection. Steps a) to c) can be performed in any order, but are preferably performed in the order described above. Subsequent steps d) and e) can likewise be carried out in any order, but are preferably carried out in the above order. The bending operations in steps a), b), and c) are performed so that each side surface and each bottom surface are bent in the same direction with respect to each rear wall.

  According to one embodiment of the method, before step d), a blank is placed along the fold line between each connecting strap and each side and / or between each connecting strap and each bottom. A folding step f) is performed. The connecting strap can provide a particularly reliable connection between each folded bottom surface and each folded side surface. In the context of this embodiment of the method, it is further proposed that step g) is followed by step g) of bonding each connecting strap to the side and / or bottom. Each connecting strap and the corresponding side or bottom can be connected to each other firmly and cost-effectively by means of an adhesive connection.

  The object is to finally wrap the outer box folded from a blank of the above kind, at least one individual box for each area of the blank, and means for fixing the individual box to the surface / inside of the outer box It is also achieved by a packaging system comprising It is preferable that one individual packaging box is accommodated in each surface area of the exterior box. Therefore, the outer box having six surface areas preferably accommodates six individual packaging boxes. Alternatively, each surface area of the outer box could accommodate two individual boxes, such that an outer box with six surface areas would accommodate twelve individual boxes. Means suitable for fixing the individual packaging box are provided in order to prevent the individual packaging box from falling off the outer packaging box. Alternatively, the packaging system may comprise several stacked outer boxes. In this case, each outer packaging box comprises at least one individual packaging box for each area of the blank and means for fixing these individual packaging boxes to / in the surface of the outer packaging box.

  According to another embodiment of the present invention, it is further proposed that the means for securing the individual packaging is an adhesive. Alternatively or in addition, the means for fixing the individual box may be a fixing strap. Since the adhesive can provide a material bond between the individual packaging box and the outer packaging box, the individual packaging box can be reliably and cost-effectively fixed to the surface of the outer packaging box. It is preferable to use an adhesive that does not cause damage to the individual packaging box or leave any residue when the individual packaging box is taken out of the outer packaging box. One or more securing straps may provide a push-in and / or non-push-in connection between each individual box and the outer box, depending on the orientation. For this purpose, the fixing strap surrounds the entire outer box, or preferably only surrounds one or half of the outer box and the individual box placed there. Stackability can be improved when the two fixing straps surround only one surface of the outer box or a half of the outer strap and the individual packaging box arranged there. In this configuration, the rear walls arranged back to back are not pressed against each other by the fixing strap, so that the above-mentioned “plug-in connection” can be brought about very easily in the stacked arrangement. The use of a fixing strap made of transparent plastic is preferred. The reason is that it is inexpensive and does not block the view on the front side of the individual packaging box.

  The invention will be described in more detail below with reference to the drawings, which merely show preferred exemplary embodiments.

The flat state of the blank of this invention for manufacturing an exterior box is shown. Fig. 2 shows a partially folded state of the blank according to Fig. 1; Fig. 2 shows a fully folded state of the blank according to Fig. 1; Fig. 2 shows the blank according to Fig. 2 together with an individual box and two fixing straps. FIG. 3 shows the blank according to FIG. 3 with an individual box and two fixing straps. A state in which several blanks in a completely folded state, that is, in the form of an outer box, are stacked. The flat state of the blank for manufacturing the exterior box by a prior art is shown. Fig. 7b shows an outer box made from the blank according to Fig. 7a.

  FIG. 1 shows a flat state of a blank 1 of the present invention for producing an outer box. The state shown in FIG. 1 corresponds to the initial state of the blank 1 before being folded. The exemplary blank 1 shown in FIG. 1 comprises six surface areas identified by reference signs I-VI. Each of these surface areas I to VI includes a rectangular rear wall 2, a rectangular bottom surface 3, and two side surfaces 4. The two side surfaces 4 include at least one inner side surface 4 '. These side surfaces 4 are composed of a plurality of inner side surfaces 4 'and a plurality of outer side surfaces 4 ". Two of these outer side surfaces 4" are lower in length than the inner side surface 4'. In contrast, the remaining two outer side surfaces 4 ″ are taller than the inner side surface 4 ′ and can serve as side guides. The two outer side surfaces 4 ″ having a lower length and the two outer side surfaces 4 ″ having a higher length are: The rear wall 2, the bottom surface 3, and the side surface 4 are separated from each other by a fold line 5.

  Each rear wall 2 has four sides. In one of these sides, each rear wall 2 is connected along a fold line 5 to a bottom surface 3 assigned to the rear wall 2. On the opposite side, each rear wall 2 is connected to the rear wall 2 of the adjacent surface area. The rear wall 2 of the surface area I is connected to the rear wall 2 of the surface area IV by a folding line. Similarly, the rear wall 2 of the surface area II and the rear wall 2 of the surface area V are connected to each other, and the rear wall 2 of the surface area III and the rear wall 2 of the surface area VI are connected to each other. Each rear wall 2 is connected to the side surface 4 by a fold line 5 at at least one of its four sides. In the exemplary blank 1 shown in FIG. 1, each rear wall 2 comprises two side surfaces 4. However, since the outer side surface 4 ″ is optional, the rear wall 2 of the surface areas I, III, IV and VI comprises only one inner side surface 4 ′ instead of the embodiment shown in FIG. It is also possible that, as shown in Fig. 1, the outer side surface 4 "is actually provided and one or more of the outer side surfaces 4" has a surface area smaller than the inner side surface 4 '. It is also possible to do. However, the rear wall 2 of the surface areas II and V must always have two (inner) side surfaces 4 'in order to provide connection with adjacent surface areas on both sides. The rear wall 2 of the surface area II provides a connection with the rear wall 2 of the surface areas I and III by the inner side surface 4 '. Similarly, the rear wall 2 of the surface area V provides a connection with the rear wall 2 of the surface areas IV and VI by the inner side surface 4 '. Accordingly, at least one side surface 4 of each surface area is connected to the side surface 4 of the adjacent surface area by a fold line 5. Surface areas II and V are also referred to as “inner surface areas” and surface areas I, III, IV, and VI are also referred to as “outer surface areas”.

  In the exemplary blank 1 shown in FIG. 1, the two long sides of each rear wall 2 are longer than either side of the inner side surface 4 '. Accordingly, an offset 6 is generated between the rear wall 2 and the inner side surface 4 ′. In the embodiment shown in FIG. 1, the offset 6 occurs on a central axis 7 that divides the blank 1 into two sides and separates the surface areas I, II, III from the surface areas IV, V, VI. When the blank is bent along the central axis 7 due to the offset 6, the rear wall 2 protrudes above the inner side surface 4 ′. Therefore, several blanks 1 in a folded state can be pushed in one after another as described in more detail with reference to FIG.

  The exemplary blank 1 shown in FIG. 1 further comprises a connecting strap 8. The connecting strap 8 is connected to the side surface 4 by a fold line 5 and serves to connect the side surface 4 to the bottom surface 3, for example by adhesive connection, after the blank 1 is folded. Unlike the embodiment shown in FIG. 1, the connecting strap 8 can also be connected to the bottom surface 3 by a fold line in order to provide a connection with the side surface 4 as well. The exemplary blank 1 shown in FIG. 1 further comprises a plurality of openings 9. These openings may be constituted by handle openings for carrying an outer box made from the blank 1. The opening 9 is provided in the rear wall 2, in particular by cutting the rear wall 2 or making a hole in the rear wall 2.

  FIG. 2 shows a state in which the blank 1 according to FIG. 1 is partially bent. The bottom surface 3, the side surfaces 4 ′, 4 ″, and the connection strap 8 are each bent about 90 ° along the fold line 5. The connection strap 8 is adhered to the bottom surface 3. In the configuration shown in FIG. 2, since the blank 1 has not yet been folded along the central axis 7, the rear walls 2 of the six surface areas I to VI are still arranged in one plane. 2 already indicates that by folding the blank 1, a chamber for accommodating one or two individual packaging boxes is created in each of the six surface areas I to VI.

  FIG. 3 shows a state in which the blank 1 according to FIG. 1 is completely folded. It can be seen that the basic difference from the configuration shown in FIG. 2 is that the blank 1 is bent about 180 ° along the center line 7 in FIG. Therefore, the rear walls 2 of the surface areas I, II and III are in contact with the rear walls 2 of the surface areas IV, V and VI and are arranged in particular back to back. Moreover, since the opening part 9 is arrange | positioned symmetrically with respect to the center axis line 7 at the rear wall 2, a finger can be passed through the two opening parts 9 arrange | positioned back-to-back after bending work.

  FIG. 4 shows the blank 1 according to FIG. 2 together with a plurality of individual packaging boxes 10 and two fixing straps 11. The individual packaging box 10 is made of a beverage carton made of a composite material having a discharge port, for example. One individual packaging box 10 is arranged in each of the six surface areas I to VI of the blank 1. The rear wall 2, the bottom surface 3, and the two side surfaces 4 are adjacent to the individual packaging box 10 and hold the individual packaging box 10 in a predetermined position. In order to fix the individual boxes 10, two transparent fixing straps 11 are wound around or stretched around the blank 1 and the individual box 10. In the exemplary blank 1 shown in FIG. 4, one fixing strap 11 is wound around the individual box 10 in the area I, II, and III, and the other fixing strap 11 is in the area IV, V. , And the individual packaging box 10 of VI. These fixing straps 11 are wound around the individual packaging box 10 and the blank 1.

  FIG. 5 shows the blank 1 according to FIG. 3 together with a plurality of individual packaging boxes 10 and two fixing straps 11. It can be seen that the basic difference from the configuration shown in FIG. 4 is that the blank 1 is bent about 180 ° along the center line 7 in FIG. Therefore, the rear walls 2 of the surface areas I, II and III are in contact with the rear walls 2 of the surface areas IV, V and VI and are arranged in particular back to back. Moreover, since the opening part 9 is arrange | positioned symmetrically with respect to the center axis line 7 at the rear wall 2, a finger can be passed through the two opening parts 9 arrange | positioned back-to-back after bending work.

  FIG. 6 shows several blanks 1 stacked in a fully folded state, ie in the form of an outer box. This stack includes five blanks 1 and the upper four blanks 1 are filled with individual boxes 10. These individual boxes 10 are held in the blank 1 by transparent fixing straps 11. The combination of the outer box, the individual packaging box, and the fixing means is also referred to as a packaging system. In contrast, the bottom blank 1 is not filled with an individual box, so the rear wall 2, bottom surface 3 and side surfaces 4 ′, 4 ″ of the blank 1 are visible. The configuration shown clearly shows that the load bearing capacity of the blank 1 is large, the bottom blank 1 being four blanks 1 that are completely filled with an individual box 10 even when empty. Therefore, even when the individual packaging box 10 is first removed from the lowermost outer packaging box, the stability of such stacking is ensured.

  FIG. 7a shows the flat state of the blank 12 for producing an outer packaging box according to the prior art. The blank 12 includes a bottom surface 13 disposed in the center. The bottom surface 13 is connected to four side surfaces 14 consisting of two high side surfaces 14 ′ and two low side surfaces 14 ″. Each high side surface 14 ′ is connected to two connecting straps 15. The bottom surface 13, the side surface 14, and the connection strap 15 are separated from each other by a fold line 16.

  Fig. 7b shows an outer box 12 'made from the blank 12 according to Fig. 7a. For this purpose, the four side surfaces 14 were first bent 90 ° upward along the fold line 16. Thereafter, the connecting strap 15 was also bent 90 ° along the fold line 16 so that the connecting strap 15 formed an overlap 17 with the lower side 14 ″. In the region of the overlap 17, the lower side 14 ″ is connected to the connection strap 15 in particular by adhesive connection. Instead of this order, first only the two tall side surfaces 14 'are folded, then the connecting straps 15 are folded, so that the short side surfaces 14 "are outside the area of the overlap 17, and finally the length It is also possible to bend the two low side surfaces 14 ".

  The blank 12 shown in FIG. 7a and the outer box 12 ′ shown in FIG. 7b are FEFCO-ESBO convention 0460 (FEFCO = Federation Europeen des Fabricants de Carton (European Association of Homogeneous Paperboard) = European Solid Board Organization-Europaeische Organization fuer Vollpappe).
