The aim of the invention is to provide a novel crate of this type comprising multiple cavities, which guarantees significantly increased rigidity with an optimum utilization of material and production processes. To achieve this, a stabilizing strut, which connects the base to the upper part is provided between at least two rows of cavities.

Description

The present invention relates to a Mehrlochsteige for containers such. B. yogurt cups or the like, according to the preamble of claim 1.

A Mehrlochsteige with the features of the preamble of claim 1 is in document US-A-2 337 197 disclosed.

Here, the stabilization bar has two folding surfaces, which are in the blank to the edges of the cut befündlich.

Such Mehrlochsteigen be for the holder and the transport of food cups such. As yogurt cups, cream cups, etc. used. Here, filled Mehrlochsteigen be stacked on pallets, and transported, for example, wrapped with shrink film and stored in the store. Therefore, such multi-hole trays must firstly ensure sufficient stability both in themselves and in the stacked arrangement to prevent damage to the food cups during transport.

From the DE 34 23 091 C2 a blank of folding material for a Mehrlochsteige is known. In this case, when unfolding the wall areas holding webs which are punched out in the blank, raised and glued together at their respective ends. The resulting tray has only a very low rigidity, with the result that the food cups can be damaged when stacking the individual crates and / or during transport. In addition, it is expensive to arrange advertising imprints in the interior of the crate.

From G 85 07 721.6 a stackable tray is known, are also set up by inner folds of the outside edge regions by approximately 90 ° in the interior area located webs, wherein the webs are in this case in one piece with the remaining material in combination. This embodiment also has the disadvantage of a very low rigidity and a complex advertising treatment of the outsides of the unfolded crates. In addition, in the above-mentioned climbs, the degree of material utilization is comparatively moderate.

The present invention has the object to provide a novel multi-hole walker of the generic type, which significantly improved rigidity at elevated Material efficiency (material reduction) guaranteed. In addition, the Mehrlochsteige to ensure relief of the cup.

The present invention is achieved in the generic Mehrlochsteige by the features of claim 1. The stabilizer bar thus runs, so to speak, between two rows of holes (possibly with interruptions) through the multi-hole walkways, connecting the webs with each other and thus ensures a significantly increased deflection stiffness, torsional stiffness and compared to the known Mehrlochsteigen where stabilization takes place only in the edge region Stiffness parallel to the plane of the ground. The stabilizer bar may extend substantially continuously between two rows of holes. The stabilization bar can also be interrupted, while still ensuring the necessary stabilization. The invention also allows a material saving compared to conventional blanks of up to 40%.

The stabilizing web is expediently formed by a respective folding of two folding surfaces, which extend in parallel to one side of the blank through each other.

The two above-mentioned folding surfaces are expediently glued together after unfolding. The stabilization bar is therefore a turn two-layer structure, which floor and top part alike with each other.

Conveniently, because of the folding of the folding surfaces for the production of the stabilizing web, mutually associated regions-the surface state considered-are offset relative to one another, wherein these regions are brought into position only by the folding of the folding surfaces, ie by the production of the stabilizing webs.

According to one embodiment of the multi-hole walkway according to the invention, the blank comprises three folding surfaces, wherein two lateral folding surfaces are foldable against a central folding surface. The lateral folding surfaces are in this case with the respective webs in connection, so that are arranged by folding the webs with distance to the ground.

In an advantageous manner, in each case one stabilizing web is provided between all rows of holes, as a result of which optimum rigidity can be achieved.

If, according to a possible embodiment of the present invention, the stabilizing web is so aligned for cutting that it runs parallel to the row of holes with the larger number of holes, an optimal degree of utilization of material is given. The folding surfaces with each other are each about a bending line, z. B. a perforations comprehensive line or a line with less material thickness, in conjunction.

Furthermore, according to a further embodiment of the invention, support tabs can be provided in the area of the stabilizing webs, which in the erected state of the tray is directed upwards, ie. H. are directed only at the top adjacent adjacent crates and ensure a recording and introduction of the force in the crate. As a result, the overall cohesion of the stacked crates is improved and a subsequent impairment of the goods to be transported excluded.

A further embodiment of the present invention is characterized in that two stabilizing webs are provided side by side. As a result, on the one hand, the rigidity of the crate is still increased, on the other hand, a desired dividing line between the two stabilizing webs may be provided so that the crate can be involved with little effort in smaller crates.

Conveniently, the adjacent with such a dividing line folding surfaces of the respective stabilizing webs are not connected to each other, so that the crate can be separated only along the desired dividing line. Alternatively, the two adjacent to the desired dividing line folding surfaces are connected to each other via separable bonds. If required, they can be separated together with the desired separating line for separation. The separation of such crates into smaller crates can thus with the multi-hole walkways according to the invention at any time during the use of the crate for example, by the purchaser, the retailer or, if desired, by the producer before being cleared for sale.

Furthermore, foldings are expediently provided in the corner region in which two surfaces are folded against one another and connected, preferably glued, to one another. As a result, an increase in the corner stability is ensured.

Characterized in that the blank has an edge region which is directed in the folded state with its top of the bottom corresponding top side outwards, an advertising imprint on the top of the floor can thereby be made simultaneously for the externally visible side area. As a result, the highly visible top of the blank can be printed.

Conveniently, the flat blank at the top, d. H. printed on the top of the floor.

Conveniently, on the side of the crate, which runs perpendicular to the respective stabilizing web, a tab upwards and the adjacent tab downwardly outwardly folded. Then both tabs are glued together after an offset is completed by the erection of the crate. This also results in a special stiffening of the crate.

With particular advantage, a partial web can be provided at least between two holes lying next to one another in a row, which extends over a partial region in the transverse direction of the series of holes. The holes are therefore only partially limited. This results in a particularly high torsional rigidity, since the ground is not interrupted in the transverse direction. In addition, this has the advantage that the continuous floor is available as a large area for the advertising print.

Conveniently, the partial web can be connected via a support web to the ground, so that the partial web has a stable grip. In addition, a plurality of partial and support webs leads to an increase in the overall stability of the Mehrlochsteige.

The support web can run substantially parallel to the stabilizing webs. Thus, the support web extends substantially perpendicularly between the upper part and the bottom, which in turn leads to an increase in the torsional rigidity parallel to the plane of the soil. But it is also possible that the support bar runs obliquely to the top and bottom.

Advantageously, projections may be provided in particular for the lateral retention of a container in the region of the upper part. In particular, these projections may be provided in the region of the partial webs, whereby the partial webs a double function, namely the maintenance of a container on the one hand and the increase in the rigidity of the crate on the other hand, meet. It is particularly expedient if the projections have a curved contour, so that the cup to be used can be stabilized particularly well in its position.

A crate with the above-described partial webs is characterized by their increased material savings of about 28% compared to commercial crates.

The partial and support webs may be arranged so that they are positioned in a series of holes, in particular in an inner row, directly opposite one another. This has the advantage that the projections described above in the region of the partial webs equally stabilize the inserted container in its position from both sides. The stability of the entire crate can be increased.

In the marginal rows of holes, however, the partial and support webs may be provided only on the side of the edge regions.

A further advantageous embodiment of the crate provides that at least one transverse stabilizing web is provided transversely to the stabilizing webs. The transverse stabilizing web is arranged substantially perpendicular to the stabilizing web and also extends between two rows of holes arranged one behind the other. As a result, the torsional stiffness and load capacity of Mehrlochsteige is further increased.

Advantageously, the transverse stabilizing web can be separated at a desired separating line. Depending on requirements, the multi-hole walkway can be split at the desired dividing line with a few simple steps into smaller trays. The adjacent to the desired dividing line folding surfaces can, for. B. be connected only in its lower part via a line comprising a perforation. Additionally or alternatively, the two folding surfaces can be connected to one another via a separable bond. A separation of the transverse stabilizing web can thus be made as in the stabilizing webs described above.

The regions of the multi-hole webs arranged on both sides of the transverse stabilizing web can be pivoted relative to one another so that the multi-hole webs can be arranged on a roof-shaped base or the like such that the two regions of the multi-hole webs are arranged at an angle to one another and each point in a different direction. This may be advantageous for the presentation of the containers arranged in the multi-hole trays.

Further, in the region of at least a portion of the transverse stabilizing web support tabs may be provided which bent in the unfolded state of the multi-hole risers - as the above-described support tabs on the stabilizing webs - a support of Mehrlochsteige to ensure arranged Mehrlochsteige. As a result, a sufficient distance of the overlying crate is provided to the containers provided in the underlying tray, and the containers are not affected by the weight of the overlying crates.

In a further advantageous embodiment variant, in each case a partial web is provided in the region of the partially delimited holes, which extends over a partial region in the transverse direction of a series of holes. This results in the advantage that the cups used are particularly effectively secured within the partially limited holes or the respective recess against slipping sideways. The partial webs therefore on the one hand have a stiffening effect in the Mehrlochsteige and on the other hand, they cause a good grip of the cups within the openings.

The respective partial web is advantageously via a support bar with the ground in connection. The support bar also leads to a better grip of the cup and a increased stabilization and torsional rigidity of the entire crate. Also by the crates placed on it a better hold of the cups is brought about.

The partial web or the support web may expediently be arranged in each case in the middle of a partially limited hole. This has the advantage that the cups used are uniformly stabilized in position on both sides.

Advantageously, the support bar from the partial web to the bottom run obliquely inward, so that the cups used have an even better grip and are optimally secured against slipping.

Furthermore, the width of the support bar can increase in the direction of the ground and z. B. be trapezoidal. This training also ensures a particularly stable seat of the cup.

It is possible that in every second row of partially limited holes, the partial and supporting webs are arranged directly opposite one another. For example, the partial and supporting webs can be arranged directly opposite one another only in the outer rows of a crate, in order to realize a symmetrical construction of the crate and a uniform distribution of forces, in particular with cups used.

A further advantageous embodiment provides that the stabilizing web is partially interrupted at least on one side. The stabilizing web is merely constructed of partial webs or folded surface sections, which is sufficient, however, for stabilizing the multi-hole webs and increasing the rigidity. The advantage of this embodiment is that less material is needed and the Mehrlochsteige is even easier.

The stabilizing web can be completely interrupted in regions or interrupted only on one side, in particular alternately with the side adjacent thereto, so that overall there is a continuous stabilizing web.

The stabilizing web can advantageously be interrupted by webs provided between the containers. The webs are thus worked out of the stabilizer bar and are thus part of the shell.

Conveniently, webs may also be provided on the edge region, between which the containers can be positioned. These webs may be formed at least in some areas like the webs arranged on the stabilizing web, so that the containers used are stabilized in the same way both in the middle region and in the edge region. The edge region can additionally be covered by an edge-side tab which is joined together with the areas remaining between the webs and thus extends between the bottom and the top part.

Advantageously, each two adjacent webs may form an at least partially defined hole for receiving a container. The containers experience thereby an immediate support of the webs, so that a particularly good grip is ensured.

The webs pointing at the stabilizing web on both sides are offset in relation to one another in this embodiment, so that they remain firmly connected to the stabilizing web. The asymmetry formed by the staggered arrangement of the webs simultaneously leads to an increase in the torsional rigidity of the multi-hole walkways. The webs can be only slightly or completely offset from each other, so that their adjacent sides no longer overlap.

Conveniently, the arranged on two adjacent, in particular parallel to each other, stabilizing webs arranged webs or arranged on a stabilizing web and the adjoining edge region webs directly opposite each other, so that the freely projecting ends of the webs can be interconnected and on this Stabilize way.

In particular, the webs may overlap at their free end portions so that they are stably joined together. For example, the webs may be glued together at their free, overlapping end regions.

The webs lying opposite to the stabilizing webs or to the webs of stabilization and the opposite edge region can not overlap, and their free ends can each be connected to the bottom with a connecting tongue.

Reference numeral 1 in Fig. 1 A indicates the flat blank for producing a first embodiment of the crate according to the invention. It is expediently to material which is provided with corresponding punches or partial punches. The in the Figures 1-7 roughly drawn, continuous lines shown punched, whereas roughly drawn but broken lines with a continuous fine line represent partial punches for the generation of creases.

The packaging material blank has a bottom 2, which in plan view of the Fig. 1 you can see. This bottom 2 is provided with an advertising imprint not shown over the entire surface or part of the area. In the bottom 2 areas (in the planar state) are provided, which are provided as upper part 3 and are arranged after unfolding of the blank for the production of Mehrlochsteige in a plane different from the level of the bottom 2. This upper part 3 comprises individual webs 4, wherein two adjacent webs 4 a hole for receiving a container, such as. B. form a yogurt cup.

In the respective edge region 5 of the blank 1 curved areas are also provided, which are arranged offset in the flat state of the blank to the associated inner webs 4. The cut to Fig. 1 has two stabilizing webs 7, which in the illustration according to Fig. 1 each transverse to the Pass blank 1 from one side to the other. Each stabilizing web 7 is formed between the folding surfaces 8 and 9, wherein the folding surface between the folding surfaces 8 and 9 during the unfolding of the multi-hole riser according to Fig. 1 B is pulled upward so that the two folding surfaces 8 and 9 come into mutual contact. Likewise, a further folding surface 10, which connects the web 4 with the folding surface 9 as a tab, collapsed, so that according to Fig. 1 B the crease line between the folding surface 10 and the web 4 in this case lies in the same height as the crease line between the folding surfaces 8 and 9. Part of the stabilizing web 7 is an approximately half-height folding surface 20 at the beginning of the web 4, which is folded against the folding surface 8.

Furthermore, a continuous folding surface 21 of the bottom 2 is folded against the edge region 11 and optionally glued.

When unfolding the Mehrlochsteige according to the manner previously described, the curved portions of each edge-side web 4 and the curved portions of the edge region 5 come to the absence of the offset in the correct position and together form a hole 6 for receiving a (not shown) container. The areas of the floor 2 are in Fig. 1 B because not cut, shown in dotted lines.

In addition, the small side portions 11, which are parallel to the reinforcing webs 7, folded down by 90 °, so that the printed side is visible outside.

Furthermore, at least some of the edge tabs (see edge tab 17) are folded down and - after canceling the offset - glued to the upwardly folded edge tab 18. In addition, the corner flap 19 is folded over by about 90 ° and also glued to the edge flap 18.

In the region of each stiffening web 7 is, produced by a punching, a support tab 13, which in the unfolded state of the Mehrlochsteige bent upwards ensures a support of the Mehrlochsteige adjacent Mehrlochsteige in the stacked composite.

According to the in Fig. 2 A illustrated second embodiment of the multi-hole walkways according to the present invention are each two stabilizing webs 7 in the transverse direction (see. Fig. 2 A) running arranged. In this embodiment, each stabilizing web 7 of a folding surface 8 and a folding surface 9, the connecting crease line is after unfolding of the stiffening web or the crate in a plane above the bottom 2 and above the respective web 4 itself. In addition, there is an identically constructed stabilizing web 7. Both stabilizing webs 7 are characterized by a desired Trennline, z. B. perforation line in Fig. 2 A , separated from each other. Again, the stabilizing webs 7 extend between the individual adjacent rows of holes 6 for the recesses.

This configuration allows individual rows of multi-hole risers to be separated as needed. In the embodiment according to Fig. 2 A the corner tabs 19 are glued to the upwardly folded edge tabs 18. The edge region 11 is according to the illustration after Fig. 2 B when unfolding the multi-hole risers also folded down by about 90 °, so that the advertising print is easy to see from the outside.

The bridge 4 is - see Fig. 2 B - Pulled under folding the mutual folding surfaces 20 upwards. The folding surfaces 20 additionally stabilize the stabilizing web 7 and the edge region 11. The regions of the bottom 2 are in Fig. 2 B , as not cut, dashed lines. The arrangement of the folding surfaces forming the stabilizing web is in Fig. 2 B only one half for clarity with reference numerals.

In the area of the edge tab 18 is a tab 16 which is connected to the bottom 2 and is folded inwards by 90 °.

Fig. 2C shows a small, isolated tray with only a series of recesses 6 after separation from the same arrangement Fig. 2 A , This embodiment also has corner projections 12 for improving the stackability of the entire multi-hole walkways or of an isolated multi-hole walkway.

In the Fig. 3 A illustrated third embodiment of a multi-hole walkway according to the invention also has adjacent stabilizing webs 7, each formed by the folding surfaces 8 and 9 and the two folding surfaces connecting fold line, which is located in the erected state of Mehrlochsteige at the top. In addition, there is also in this embodiment between the two stabilizing webs 7, a desired dividing line, which is configured above as a double-nominal dividing line because of outer cone of the crate. The corners are glued to each other and to each other by corner folds 15 of two triangular folding surfaces, which additionally stabilizes these multi-hole walkways. As a result, particularly stable multi-hole climbing can be produced. In addition, the edge tabs 17 down and the edge tabs 18 are folded up and glued together here, too. The edge area 11 or the advertising imprint thereon are also clearly visible from the outside due to a folding downwards in the raised multi-hole walkway.

Also from this multi-hole walk is in Fig. 3B an isolated Mehrlochsteige small size visible. Moreover, in contrast to the above-described trays according to the first and second embodiments, a double row of holes is provided here.

Fig. 4 A shows a fourth embodiment of the multi-hole walkway according to the invention, in which also two stabilizing webs 7 (see also Fig. 4B) , each consisting of folded folded surfaces 8 and 9, which are separated by a desired dividing line 14, are provided. This is also a Mehrlochsteige double hole arrangement on both sides of the stabilizing webs 7. The multi-hole walkway has webs 4, which must be glued together after unfolding the same in the area 22. The anchorages of the webs 4 are (see. Fig. 4B) arranged offset to each other in the ground. In connection with this construction and the bonding increased security against tearing is given. Likewise, a corner fold 15 takes place by means of a correspondingly formed folding of folding surfaces arranged in the corner region and optionally their bonding. The bonding of the side areas, ie edge tabs 17, 18 takes place in the manner as in the third embodiment.

In the in the Figures 5 . 6 and 7 shown blanks represents the coarse hatched area (from top right to bottom left) the bottom 2, while the finely hatched area (from top left to bottom right) is the top 3 in the unfolded state. The vertically arranged in the unfolded state of Mehrlochsteige surfaces have no hatching. In the two embodiments according to the Figures 5 and 6 is provided between two in a series of adjacent partial limited holes 6, a partial web 23 which extends over a portion in the transverse direction of the row of holes 6. The in the FIGS. 1 and 2 With reference numeral 4 marked web is thus no longer designed as a continuous web, but only extends over a portion in the transverse direction. So that the bottom 2 is no longer interrupted for the centering of the containers and an advertising imprint can be applied over a large area. In addition, the continuous floor leads to a greater torsional stiffness of the Mehrlochsteige.

Some sub-webs 23 are in each case via a support bar 24 with the bottom 2 in conjunction. The support webs 24 also increase the rigidity of the entire crate. The support webs 24 extend substantially parallel to the stabilizing webs 7. However, the support webs 24 may well also run obliquely to the stabilizing webs and thus be arranged obliquely to the upper part or the bottom 2.

In the region of the upper part 3, projections 25 are provided in particular for the lateral support of a container. These projections 25 have a curved contour in adaptation to the outer contour of the container used. The projections 25 are also provided on both sides of the partial webs 23.

Like from the Figures 5 and 6 It can be seen, in the inner row of partially limited holes 6 directly opposite part 23 and support webs 24 are provided. In contrast, in the marginal rows of holes 6, the sub-23 and support webs 24 are provided only on the side of the edge regions. These partial and support webs are sufficient to create a high rigidity of the crates.

The following is based on the embodiment according to Fig. 6 Referenced. There, a transverse stabilizing web 7 'is provided transversely to the stabilizing webs 7. This Stabilizer web 7 'leads to a further increase in the stability, the torsional stiffness and the load capacity of the crates.

At the in FIG. 8a The blank shown represents the roughly hatched area the bottom 2, while the finely hatched area is the upper part 3 in the unfolded state.

The transverse stabilizing web 7 'is separable at a desired separating line 26. The desired separating line 26 is formed as a perforation, so that the two areas of the multi-hole risers can be separated from each other in a simple manner with little effort. This facilitates above all the separation of the crates into smaller units.

The transverse stabilizing web 7 'is formed by folding against one another and mutual connection of two transverse edge regions 11 of regions arranged on both sides of the transverse stabilizing web 7'. In particular, the transverse stabilizing web 7 'is obtained by connecting the adjacent edge regions 5 or edge straps 17 and 18 and the corner straps 19 of the regions arranged on both sides of the stabilizing web 7. The two areas on both sides of the transverse stabilizing web 7 'can only be connected to one another in such a way that they are pivotable relative to one another. The two areas along the transverse stabilizing web 7 'are only connected to one another in terms of line.

Support tabs 27 are also provided in the area of the transverse stabilizing web 7 ', which ensure that the necessary distance to the tray arranged above is maintained.

At the in FIG. 7 The blank sections 23 are provided in the region of the partially delimited holes 6, wherein the partial webs 23 extend over a partial area in the transverse direction of a series of holes 6. Again, the partial web 23 is connected via a support bar 24 with the bottom 2 in connection. The arrangement of the partial webs 23 and the support webs 24 in the region of the holes 6 causes the cups used are effectively secured against lateral slipping. In addition, the partial webs 23 in conjunction with the support webs 24 have a stiffening effect of the Mehrlochsteige.

The partial webs 23 and the support webs 24 are each arranged in the middle of a partially limited hole 6 in order to equally stabilize the cup used on both sides.

In the unfolded state of the support bar 24 extends from the partial web 23, starting from the bottom 2 obliquely inwards and thus on the one hand for an even better grip of the cups used, which on the other hand can still be easily removed upwards.

The width of the support webs 24 increases in the direction of the bottom 2, wherein inner support webs 24 have the shape of an equilateral trapezoid, while the edge-side support webs 24 have a non-symmetrical trapezoidal shape. The broadening of the support webs 24 in the direction of the bottom 2 ensures a further improvement in the hold of the cup.

How out FIG. 7 Furthermore, in the respective outer rows of partially defined holes 6, the sub-23 and support webs 24 are arranged directly opposite, while in the middle row no support webs 24 are provided to the stabilizer bar 7 not by too many interruptions in its stability or To weaken strength.

In the following, the embodiment according to FIGS. 8a and b Referenced. In this Mehrlochsteige the stabilizer bar 7 is interrupted in sections. This embodiment provides in contrast to the embodiment according to Figure 1 A for saving even more material and reducing the weight of the crate.

The stabilizing web 7 is formed by a plurality of or two fold surface sections 30 to be bonded together and is interrupted by webs 4 provided between the containers and lying between the folded surface sections 30. In addition, a particularly torsionally rigid multi-hole risers is created by the connection of the individual folding surface sections 30 through the adjacent webs 4 on the upper part 3. In addition, at the same time a particularly compact construction of the Mehrlochsteige is achieved.

At the edge region webs 4 'are provided, between which the containers are positionable. The edge tab 28, however, is designed without interruptions and thus ensures a stable edge region.

Each two adjacent webs 4 and 4 'form at least a partially limited hole 6 for receiving a container. The containers are thus at the hole edges and are held securely in this way.

The webs 4 pointing at the stabilizing web 7 on both sides are offset relative to one another, so that they are fastened to the stabilizing web 7. The staggered arrangement of the webs 4 also leads to a high torsional rigidity, especially in the area of the stabilizing web 7.

The webs 4 and 4 'arranged on the stabilizing web 7 on the one hand and on the adjacent edge region on the other hand lie directly opposite one another so that they can be connected to one another at their free end regions 29. In this case, the webs overlap 4 and 4 'at their free end portions 29 (see Fig. 8b ) and are glued together in the overlap area.

Both FIGS. 9 to 11b the bottom 2 is represented by a diagonally checkered surface, while the top 3 is characterized by a hatched area. The substantially perpendicular surfaces, including the stabilizing web 7, are not hatched. The multi-hole walkways according to the FIGS. 9 and 10 is designed for the reception of twelve containers or cups, while in the embodiment according to Fig. 11 twenty cups 33 can be inserted (see Fig. 11c ).

In the embodiment of Mehrlochsteige according to Fig. 10 are contrary to Fig. 9 Stacking corners 34 are provided, which serve to improve the stackability of Mehrlochsteige.

In the in the FIGS. 9 to 11 illustrated embodiments of the Mehrlochsteige the webs 4 are arranged offset from one another such that the stabilizing web 7 is interrupted only on one side by the folded-webs 4. The between the webs 4 remaining Faltflächenabschnitte 30 are glued together to the stabilizing web 7. This embodiment ensures a significant material savings and a very good mechanical strength or torsional rigidity. The webs 4, which are located opposite the stabilizing webs 7, and the webs 4, 4 'arranged on the stabilizing web 7 on the one hand and on the other hand on the adjacent edge region, are not directly opposite one another. The end portions 31 of these webs 4, 4 'are therefore connected via a connecting plate 32 to the bottom 2.

In Fig. 9 a stabilizer bar 7 is provided while in Fig. 10 two mutually parallel stabilizing webs 7 are integrated.

From a comparison of Figures 11a and 11b is the folding or erection of the multi-hole walkway from the blank 1 particularly clear.

It should be noted that all features of the embodiments described above can also be exchanged with one another as desired. On the one hand, the multi-hole walkway according to the invention has a significantly improved rigidity and, on the other hand, an improved degree of utilization of material. In addition, the manufacturing costs (such as printing and punching) can be reduced by up to 50% because more benefits (eg 3 benefits, now 6 benefits) are possible on the print sheet. In addition, only minor punch ejection falls in the outdoor area. The blank according to the invention is therefore particularly suitable for rotary blanking. The invention therefore represents a very significant advance in the field.
