Description

The invention relates to a cardboard packaging, in particular for a liquid bag, wherein the container is substantially barrel-shaped or barrel-shaped, with two end elements and extending therebetween wall part, which consists of a plurality of parallel to the barrel axis and mutually interconnected via score lines strip elements and wherein the wall portion extends a predetermined area beyond the end members and forms a peripheral edge.

In the prior art a variety of containers and packaging for liquids, as well as other products are described. For example, Liquid containers are known in which a plastic bag is arranged from a film inside a paper or cardboard container. In these liquid containers, the opening is usually carried out by tearing or tearing the outer Kartonwandung at a predetermined location, at the same time the bag is opened with.

Another form of packaging in which a bag for storing liquids is disposed is the so-called "bag-in-box" packaging used as an environmentally friendly alternative to plastic bottles or canisters, especially for use as a supply pack become. In practice, relatively large amounts of liquid, for example up to 30 liters, are also suitable. To remove the liquid contents of the integrated in the packaging container flexible bag usually has a closable outlet, wherein in the outer packaging, a corresponding opening for carrying out the outlet opening may be provided.

In the DE 4 116 07 is described a arranged on a base container for liquids, wherein the container can be used as a party keg. For use, the container is placed on a supplied base, in which the container can be received during storage or transport. The container for holding liquids consists essentially of three elements, a front wall, a rear wall and a tubular container, which consists essentially of eight parallel juxtaposed equally sized shrouds. To record, first formed as an octagon back wall in the tubular Container introduced and provided on the tubular container two-ply folding edges folded twice, so as to define the position of the rear wall. Subsequently, the liquid-filled bag is inserted into the tubular container and introduced the front wall. Here, the front wall is also formed octagonal and also has on two opposite edges lateral support fields, which extend perpendicularly into the interior of the tubular container and are held by the filled bag on the inside of the shroud fields. Simultaneously with the introduction of the front wall and the nozzle of the bag must be inserted into a provided on the front recess. As soon as the front side is at the intended end position, folding edges are also folded twice in order to hold the front wall in position. Care must be taken when inserting the front wall for precise insertion, as the lateral support fields tilt quickly and too much pressure, the stability of the support fields is impaired. Further, since the back wall as well as the front wall are substantially held by the contents of the bag, ie, the pressure applied to the walls, there is a risk that these elements will shift easily when the bag has been emptied to a great extent. In this case, on the one hand the function, as well as the appearance of the container is significantly impaired.

The object of the present invention is to provide a carton package, in particular for a liquid bag, by which the known from the prior art disadvantages are overcome, which provides a particularly simple way of packaging and cost is both in terms of manufacturing, logistics and storage ,

This object is achieved by a cardboard packaging, in particular for a liquid bag, wherein the container is substantially barrel-shaped or barrel-shaped, with two end elements and a wall extending therebetween, which of a plurality parallel to the barrel axis and interconnected by creasing lines Strip elements is made and wherein the wall portion extends beyond the end members beyond a predetermined range and forms a peripheral edge, achieved in that the end elements are arranged directly by hinge lines on the peripheral edge and wherein on the inside of the wall part at least one locking element for fixing the end element is provided.

The present invention thus provides a package, which is characterized in particular by the direct connection of the end elements with the wall portion, as well as means for fixing the end member. As a result, on the one hand, a precise and predetermined arrangement of the end element is achieved in the wall part at a predetermined position, which thus facilitates the transfer of the cardboard packaging in the use position. At the same time the end element is held by a latching element, so that the cardboard packaging, even if it is not filled, moves, e.g. tilted, this can be the risk of shifting or falling out of the end element consists. At the same time, the time required to transfer the cardboard packaging into the position of use is considerably simplified and thus the necessary time required is shortened.

Advantageously, at least one end element may be provided at its outer edge with receptacles which cooperate in the use position with the at least one latching element. The recesses engage in the use point in a region of the locking elements and the end elements can be stabilized and positioned between the locking element and the outer edge of the tongue elements.

According to a preferred embodiment, in the position of use, the cardboard packaging can be used standing in the region of an end element or lying on at least one strip element. This significantly increases the field of application.

According to a preferred embodiment, at least one of the strip elements is substantially wider than the plurality of remaining strip elements and form a flat footprint, while the remaining strip elements have a smaller width and form as contiguous link elements formed on the stand surface barrel vault. By providing a plurality of link elements, this region of the wall part is very movable and is therefore easily in the desired shape, in particular a rounded shape, brought. Furthermore, visually creates the impression of a barrel, as the individual link elements mimic the individual wooden rods of a real barrel. Since the cardboard packaging already has a stand space, it can be arranged at any suitable location without the need for additional measures. In this case, the package can be easily stored folded together due to the large number of link elements, so that during Transport and storage only a small space requirement exists. At the same time, the packaging can be brought into a ready-to-use position without much effort.

Advantageously, the peripheral edge may be formed only in the region of the end portions of the link elements, by an enveloping edge which adjoins on both sides in the longitudinal direction, which can be bent from the link elements on a fold line arranged perpendicular to the score lines and can be applied to the inside of the link elements. Here, the folded Umschlagränder stabilize the one hand, the end edges of the cardboard packaging and at the same time a contact edge for the end elements is provided. Furthermore, the impression of a thicker container is achieved because the end portions are double-walled in this way.

Advantageously, it can be provided that the standing surface is formed by two superposed, interconnected strip elements. Since the base is made thicker than the adjoining members, the stability of the base can be further increased. At the same time, the footprint provides a portion of the container in which a carton blank can be joined to the closed wall portion without adversely attracting that juncture to a viewer in use.

According to a further preferred embodiment, the width of the standing surface may correspond approximately to the width of 3 to 10, preferably 6-7, sectional elements. This width has proven to be particularly suitable in practice to ensure a stable and secure hold of the cardboard packaging, especially in the filled state.

Advantageously, the link elements adjoining the standing surface on both sides may have a slightly greater width than the width of the further link elements, and may preferably be 1.1 to 1.4 times the width. As a result, the arrangement of the link elements around the stand area is improved. The specified width has proven to be particularly suitable in practice.

According to another preferred embodiment, the end elements can connect on both sides to the base, preferably to a strip element of the base, and extend from one corner of the outer edge of the base to the other as a circular section. The shape of the end element becomes the desired final shape the container additionally supported, since the link elements, which lay around the end elements, adapt to the shape of the end elements. Since the end elements are associated with the footprint, the positioning of the same in its desired position is simplified.

According to a further preferred embodiment, between the support surface and each end member there may be arranged a rim portion delimited by two parallel fold lines, one of the fold lines being at the position of the fold line between the link members and the envelope edge and the width of the edge region between the fold lines the width of the Umschlagrandes between the fold line and the parallel end edge corresponds. Since the width of the edge region corresponds to the width of the enveloping edges, it is possible to arrange the end elements in the use position also according to the width of the Umschlagränder in the interior of the cardboard packaging. At the same time, a uniform optical image of the packaging in conjunction with the enveloping edges is achieved by the edge regions.

Advantageously, the edge regions in the use position can rest on the inside of the standing surface and abut the end elements on the outer edge of the enveloping edges. In this way, the end elements can be pushed behind the outer edge of the Umschlagränder and so stabilized.

According to another preferred embodiment, the standing surface and the associated edge region of an end element, in particular of the end element arranged in front in the position of use, can be provided with a passage opening such that a recess is formed in the use position in the region of the base surface and the edge region lying thereon. In particular, when the cardboard packaging is to be used as a barrel-like container for liquids, a tap area is provided here, which can not be damaged by the exiting liquid, at the same time a container to be filled can be placed near the barrel.

Advantageously, the passage opening can extend mirror-symmetrically to the folding edge between edge region and base surface over the entire width of the edge region and a corresponding region of the base surface. This will ensure that the recess extends to the end member and is uniformly formed over all the layers.

Advantageously, the passage opening may be formed as a circle, rectangle or hexagon. These embodiments, in particular the rectangle or hexagon, have proved to be particularly preferred.

Advantageously, the end element can also be provided with a latching nose in the region of the passage opening. In the position of use, this locking lug covers the open edge of the double-walled standing surface formed by the recess and thus protects it.

According to a further preferred embodiment, the front end element disposed in the lying position of use in the lower portion associated with the standing surface may comprise a region surrounded by a parting line, preferably a circular section which can be removed by applying pressure to the region surrounded by the parting line. This creates a passageway from inside the container, e.g. for a tap or the like, the opening being provided just prior to actual use so that a pouch in the package is protected until actual use.

Advantageously, a flap element can be formed above the area surrounded by a dividing line, with a folding line arranged parallel to the standing area and with dividing lines extending down therefrom to the standing area, which are connected via a dividing line running at least partially on the parting line of the surrounding area are. This flap element can interact with the passage opening, in particular if larger elements are to be performed through the passage opening. At the same time it is ensured that the opening is not too large and a tap or the like is loosely arranged in the opening by the flap member is returned to its original position.

According to a further preferred embodiment, the peripheral edge may be formed by end portions of the strip elements and by an envelope edge adjoining them on both sides in the longitudinal direction, which is perpendicular to the one at Creasing lines arranged fold line of the strip elements abknickbar and can be applied to the inside of the strip elements. This embodiment is particularly suitable for cardboard packaging to be placed standing on an end member. Again, a stable attachment of the end elements is ensured on the wall part, without the visual appearance is impaired.

Advantageously, the score lines may extend across the width of the envelope edges and may be formed as relief cuts over a predetermined range from the fold edge. This allows only one long to wrap around the whole of the link elements, i. From one side of the base to the other side, extending Umschlagrand is formed, which is then applied to the inside, without this is due to the existing material surplus on the inside to serious problems, but this is absorbed by the relief cuts. In this way, the installation of the cardboard packaging is simplified because only a single part is to fold. At the same time, the elongated relief cuts additionally supported the impression of a real wooden barrel.

According to another preferred embodiment, at least one enveloping edge on at least one outer edge opposite the folding edge can have at least the at least one detent element. Advantageously, each locking element may have at least one latching lug and be formed between the latching lug and the outer edge of the Umschlagrandes a latching projection. The provision of corresponding latching elements has proved to be particularly preferred, in particular in cooperation with the end elements, since this can stabilize the end element at the intended position. A locking element here is a particularly simple and long-known element to achieve the appropriate effect. Here, it has proven in practice for the horizontally arranged cardboard packaging, when a locking element of the standing surface opposite and a locking element on both sides of the base is arranged on each Umschlagrand because this arrangement has been found to be sufficient to stabilize the end member stationary. In particular, in the horizontal position of use, a latching element of the standing surface opposite and one latching element may be provided on both sides in the vicinity of the base. A corresponding number of locking elements has proven sufficient in practice to secure the end elements.

Advantageously, at least one end element can be held in the position of use between the outer edge of the enveloping edge and the latching element. The end member is thus held between the locking element and the outer edge in a substantially clamping arrangement. At the same time allows the arrangement of only one locking element, and the additional given hold of the end member by its attachment to the wall part, that the end part can be repeatedly opened and closed without the holding force decreases.

According to another embodiment, each end element may extend in extension of the Umblagrandes, the associated hinge line each extending between two adjacent crease lines and extending from one corner of the hinge line to the other as a circular section. In practice, the width of a strip element has been found to be sufficient to ensure a secure attachment of the end member to the wall part.

Advantageously, two mutually spaced end elements can be arranged on an enveloping edge, which lie on one another in the standing position of use. In this way, in particular in the standing position of use, a double-layered and therefore substantially more stable floor area is provided.

In this case, two mutually spaced end elements can be arranged on an enveloping edge, which lie on one another in the standing position of use. Advantageously, a flap element can be formed above the area surrounded by a dividing line, with a folding line arranged parallel to the standing area and with dividing lines extending down therefrom to the standing area, which are connected via a dividing line running at least partially on the parting line of the surrounding area are. By means of these embodiments, a passage opening to be opened only before the actual use is provided, which is located in the wall part, so that this embodiment is suitable in particular for standing use positions.

According to a further preferred embodiment it can be provided that the receiving line of the front end element facing the hinge line is formed semicircular. This embodiment facilitates the construction of the container from the transport position to the use position by a finger in the semicircular recording can be introduced and a pressure on the wall part can be exercised, so as to simplify the introduction of the front end element.

According to a further preferred embodiment, the front end element may have two buckling regions which are delimited by two fold lines formed on the outer surface of the end element, the fold lines being opposite to each other and extending between two points on the outer edge of the end element. This embodiment again serves to simplify the construction of the container, since these areas initially yield during insertion of the end element into its latching position and can subsequently be stabilized on the outer edge of the enveloping edge.

Advantageously, each fold line can extend from the recess adjacent to the hinge line on the outer edge edge. This position has proven to be particularly suitable in practice, since only a small edge region can fold away and so the stability of the end element is only slightly affected.

According to another preferred embodiment, the cardboard packaging may be formed from a one-piece Kartonagezuschnitt. This reduces storage costs, since only a single part must be stored, at the same time simplifies the assembly of the container considerably.

According to another preferred embodiment, the cardboard packaging may consist of corrugated cardboard.

Advantageously, the packaging can be transferred from a flattened transport position into a barrel-shaped use position. Consequently, the cardboard packaging can be transported flat, so that only little space is required, and is brought into its actual shape just before filling.

In this case, the wall part in the region of the link elements may have two opposing hinge lines extending over the entire length and in the flat state form two outer edges of the wall portion and wherein each hinge line formed around a crease line and arranged from two sides and parallel to the crease line Crease lines can exist. This makes it possible not to attract the hinge lines in addition, but this in the entire shape of the container integrate. In particular, the substantially barrel or barrel shape of the cardboard packaging is not affected.

In the lying position of use, the footprint in the flattened transport position can be arranged centrally and the width of the base can be less than 45%, preferably less than 40% of the total width between the hinge elements. The central arrangement of the base contributes in particular to the better training form of cardboard packaging. By limiting the width of the pedestal as indicated, the impression of a barrel can still be obtained, even if a flat area is present as a pedestal.

Advantageously, it can be provided that the end element arranged in the use position at the rear or at the bottom can be arranged in the transport position in the interior of the wall part. As a result, the size of the collapsed in the transport position container is reduced to a minimum, since only one end member protrudes beyond the wall part. At the same time, the end element is additionally protected against transport damage.

The present invention further relates to a liquid container comprising the described cardboard packaging and a liquid-containing bag which is arranged in the interior of the cardboard packaging.

The liquid container according to the invention is particularly suitable as a kind of "bag and box" container, wherein the flexible bag is arranged in the cardboard container. As a result, in particular a separate disposal of carton and emptied plastic bag for environmental protection is particularly simplified.

Advantageously, the bag containing a liquid can be provided with a dispensing device or pouring device, which extends through the passage opening which can be provided in the front end element and can be fixed with the folding element. In this way, the pouring device is fixed in the end element.

Advantageously, the pouch containing a liquid may preferably be a 3-liter pouch and the paperboard package comprises twenty-two limbs approximately 20 mm wide. This size has proven particularly useful in practice.

FIG. 6

in perspective, a cardboard packaging, which can be produced with the cardboard cutout according to FIG. 6 in the transport position,

1 shows a cardboard cutout for the cardboard packaging 1 according to the invention, comprising two end elements 2, 3 and a wall part 4. The wall part 4 is designed as a substantially rectangular element which has two strip elements 5, 6 at the ends in the longitudinal direction. The wall part can be brought into a substantially barrel-shaped operating position by bringing the two strip elements 5, 6 together and gluing them together, thus forming the base element.

The region of the wall part 4, which extends between the two strip elements 5, 6, is provided with grooves 3 extending parallel to the longitudinal edge of the strip elements, ie in the transverse direction of the wall part 4, over the entire region between the strip elements disassemble the strip elements into individual link elements 8. The width of each individual link element 8 is in this case much smaller than the width of the substantially equally wide strip elements 5, 6. Thus, a strip element may have a width of 120-130 mm and the width of a link element is 20 mm. Only the directly adjacent to the strip elements 5,6 link elements may be slightly larger than the remaining intermediate.

Two of the score lines 9, 10 are additionally designed as hinge lines, i. In addition to the existing Rillline two further parallel thereto arranged score lines are formed. These hinge lines serve to transfer the container 1 in a flat lying transport position. For this purpose, the hinge lines 9, 10 are each arranged at the same distance from the strip elements 5, 6. Further, the width of the portion of the link members 8 disposed between the hinge lines corresponds to the width of the link members adjacent to the tab members and the link members adjacent thereto, up to the hinge lines when the tab members 5, 6 are in the stacked state.

The fold lines 11,12 in the region of the link elements 8 form the outer edges of the container in the unfolded state. From these fold lines extend on both sides Umschlagränder 13,14, which extend over the entire width of all the link elements 8. Each wrap-around edge 13, 14 is in this case formed with a plurality of relief cuts 15, which extend from the fold line 11, 12 in extension of the score lines 7 over a predetermined distance.

Furthermore, each enveloping edge 13, 14 is provided with three latching elements 16, 17, 18, 16 ', 17', 18 ', which are arranged on the edge of each enveloping edge 13, 14 remote from the link elements 8 and with a latching projection 19, 20, 21,22,19 ', 20', 21 ', 22' are formed. Here, the locking elements 16,18 ', 16,18' are the same design, with a extending from the bumper edge 13,14 from web on which a locking lug adjoins, so that between the locking lug and the end edge of the Umschlagrandes the locking projection , The latching elements 16, 18, 16 ', 18' are each arranged in the area bounded by the hinge line and the strip elements 5, 6, the latching projection opening in the direction of the strip element 5, 6.

The latching elements 17, 17 'are arranged centrally in the area surrounded by the hinge lines on the Umschlagrände 13,14 and have a central web with it on both sides extending latching noses, wherein two locking projections between the latching element and the end edge of the Umschlagrandes are formed.

During operation or during transfer to the transport position, the two strip elements 5, forming the base elements, are glued to one another and the score lines 7 are bent over. Further, the Umschlagränder 13,14 are applied to the inside of the link elements 3 and the webs of the locking elements as well as the associated areas of the Umschlagränder glued to the inside of the link elements.

As further shown in Figure 1, the strip element 5 is provided with the end elements 2, 3, wherein between the strip element 5 and the end member 2 and 3 respectively an additional edge portion 21,22 is arranged. The edge portion 21,22 is formed by the fold line 11 ', 12' and by a fold line 23,24 arranged parallel thereto. The width of the edge portion 21, 22, i. the distance between the fold line 11 'and 24 or 12' and 25 in this case corresponds to the distance between the fold line 11,12 and the outer edge of the envelope edge 13,14. In operation, the edge portions 21,22 abut against the inner wall of the strip element 5. Here, in the transport position, the edge portion 21 of the rear end element 2 is already glued to the inner wall of the strip element.

The end elements 2, 3 extend in a circular manner from the edge section and are provided at their outer edge with three recesses 26, 27, 28, 29, 30, 31 arranged at a predetermined distance from one another. These recesses are arranged so that they correspond to the position of the webs of the locking elements, so that in the use position, the webs are received by the recesses, and a portion of the outer edge of the end elements between the locking projections and the Umschlagrand is held for stabilization. Here, the depth of each recess, i. the distance to the outer edge is approximately the height of the cardboard.

In the end element 3, the recess 30 is formed semicircular, so that the web is not received adjacent. Among other things, this semicircular opening 30 makes it possible to transfer the cardboard packaging from the position of use into the transport position by exerting a tension on the inside of the end element by engaging in the cardboard packaging.

Furthermore, the end element 3 has two folded edges 32, 33 which are arranged on the outer surface of the end element 3 and which extend from the recesses 29, 31, ie the end of the recess spaced from the base element 5, to the outer edge. The two fold lines 32,33 are in this case inclined towards each other and terminate preferably at positions of the outer edge that are spaced farther apart than the width of the pedestal element 5.

The end member 3 further includes a circular portion 34 which is delimited by a parting line, e.g., a line with long cuts separated by short webs, so that by applying pressure to the portion 34, a passage opening can be formed. In this case, the region 34 is arranged in the lower half of the front end element 3 assigned to the strip element 5. On the side facing away from the strip element edge or portion of the region 34, a flap member 35 is arranged, comprising a fold line 36 which is arranged parallel to the fold line 11, and extending from this vertically downwards on the stand elements dividing lines, which up extend to the region 34 and connects to the dividing line of the region 34.

Furthermore, the strip elements 5, 6 are provided at a transverse edge, in the strip element the edge facing the end element 3 is provided with a recess 37, 38. In the case of the strip element 5, the recess continues in a mirror image over the edge region 22. If the strip elements are glued to each other in the position of use and the edge region 22 is glued to the strip element, a uniform recess is formed which extends over all the layers. The end element 3 further has, in the region of the recess which is formed in the edge region 22, a latching projection 39 on which extends in the position of use over the three layers and protects them.

FIG. 2 shows the cardboard packaging according to the invention in the laid-flat transport state. The outer edges of the cardboard packaging are formed here by the hinge edges 9, 10 and the fold lines 11, 12. On one side, the edge portion 22 and the end portion 3 extends beyond the wall element. The end portion 2 is arranged in the transport position in the interior of the wall part.

FIG. 3 shows the cardboard packaging according to the invention in the position of use. Here it becomes clear how the individual link elements 8 extend from the pedestal element and are stabilized by the circularly shaped end elements 2, 3 in the form of a barrel vault. Here, the front end element 3, corresponding to the rear end element, not shown, in the region of the individual link elements 8 at the outer edge of the Umschlagränder, ie between held the Umschlagrand and the locking projections, and are spaced in the region of the base by the edge portion of the fold line 12.

In the area of the front end element 3, the circular area 3 has been removed by exerting pressure on the parting line, so that an opening has been created.

In FIG. 4, the cardboard packaging is again shown in the use position with inserted dispensing or outlet device.

The outlet device is in this case fixed in the passage opening of the region 34, wherein the introduction of the dispensing device of the folding mechanism 35 ensures that the dispensing device is arranged in the passage opening, in particular from the interior of the cardboard packaging is carried out and finally a portion of the dispensing device with a smaller diameter in this Position can be fixed by returning the flap element 35.

FIG. 5 shows another cardboard cut-out for the cardboard packaging 1 according to the invention, wherein the cardboard blank shown in FIG. 5 is one which is particularly suitable for standing use positions.

In the description of the cardboard blank as well as the following Figure 6, like elements with identical reference numerals as in Figure 1 are designated. Furthermore, the description will be directed in particular to elements which differ from each other, elements which are not described correspond to the element in FIG. 1.

In contrast to Figure 1, the wall portion 4 of the cardboard blank shown is formed by a plurality of mutually parallel and separated by individual score lines 7 strip elements 40 which are formed substantially the same width over the entire length of the wall portion. An enveloping edge 13, 14 formed on both sides of the strip elements 40 each extend over a majority of the link elements, ie two link elements 41 are excluded from the enveloping edge and are glued in use to the opposing link elements 42 of the wall part 4. From the Umschlagrand 13, which forms the upper edge in the standing position of use extends in the region of the link members 42, the end member 3, wherein the end member 3 only in the region of the width of a strip element is connected to the envelope edge 13. In contrast to FIG. 1, the enveloping edge is not formed as a single connected strip, but is divided into two parts, wherein in the region of the link elements 42 a section separated from the rest of the enveloping edge is arranged. As a result, the mobility of the end element 3 is increased during the closing and / or opening of the cardboard packaging.

Here, the end element 3 has both the already described in Figure 1 click lines 32 and 33 as well as the circular recess 30.

At the bottom of the envelope 14, which is arranged in the position of use below, two end elements 44, 45 arranged starting from the end edge remote from the element elements 40 are arranged. These end elements 44, 45 are connected only over a width of a link element 40 with the Umschlagrand. The two end members 44, 45 are arranged so that one end member 44 is equidistantly spaced from both hinge lines 9, 10 and the second end member 45 is equidistant from the hinge line 10 as the end member 44.

In contrast, the end member 3 is disposed immediately adjacent to the strip line adjacent to the hinge line 9.

The end member 45 is further provided with a crease line 46, which is arranged parallel to the fold line 12 and the end member divided into two approximately equal halves.

In use, the half of the end element 45 facing away from the wall part 4 is glued to the half of the end element 44 arranged on the wall part 4. In this way, it is possible to arrange both end elements together in the interior of the wall part, wherein the end elements automatically erect when transferring the wall part from the transport position in the barrel-shaped in the desired position, superimpose and fix there. Since the two elements are mounted opposite each other on the Umschlagrand 14, no additional fixation of this double-walled end member 44, 45 is necessary.

In contrast to the figure 1, the locking elements 16, 18 are formed with mutually facing locking lugs and thus fix the end member third

In the region of the wall part 4, a circular opening 47 and a flap element 48 are additionally arranged, which correspond in shape and effect to the circular area 34 and the flap element 35. In this case, the flap element 48 extends over the width of two strip elements.

FIG. 6 shows the cardboard packaging 1 arranged in a standing manner from the blank according to FIG. 5. In this case, the circular region 47 has already been removed and the flap 48 has been pressed out of the interior.

Particularly clear in this figure, the region of the Umschlagrandes 13 on which the end member 3 is arranged, and which is formed as a separate Umschlagrandabschnitt only on the two link members 42.
