Description

A HEIGHT-PERSPECTIVE EFFECTIVE PACKAGING COMPOSITION Technical Field The invention relates to a collapsible packaging assembly, associated pallet and lid for use in transportation, meeting needs for effectiveness in terms of volume aspects, especially in unfolded mode.

Background of the Invention As is known in the art, there exist packaging assemblies which can be folded into a compact unit and unfolded and erected to provide a box body for containing a product or materials (e.g. bulk materials) to be shipped or stored.

Such packaging assemblies include a collapsible frame (also referred to in Dutch as jacket) for forming the box body when unfolded, and are adapted for use with a forklift truck with forks to lift the assembly.

Moreover, such packaging assemblies have a (bottom or base) plate, the plate providing a bottom and the foldable frame in the unfolded condition forming the upright walls for the box in the erected condition, the plate and the folding frame being of a corrugated cardboard material.

Typically the (bottom or base) plate is provided with side flaps projecting above the plate, defining an open box, for fitting the frame into the open box, wherein the frame can be received in the folded condition in the open box. within the outer perimeter as defined by the side flaps, and when unfolded to be assembled by removably mounting a portion of the outer surface of one of the open ends of the expanded frame - the frame defines two open ends when unfolded - the frame against the inner surfaces of the side flaps of the open box during the set-up of the packaging assembly.

This part of the outer surface (of the frame) which is removably fitted can be seen as the lower part of the frame when placed in the open box.

Prior art packaging assemblies supplement the corrugated board with a first set of beams to reinforce the corrugated board; and a second set of beams connected to the first set of beams adapted to insert the forks of a forklift truck to lift the assembly.

When transporting package assemblies folded into compact units to the destination where they are used and thus loaded with a product or material to be shipped or stored, it is important to be able to stack as many package assemblies on top of each other as possible. The discrete number of such package assemblies that can be stacked maximally depends on the height of the transport vehicle and the height of the package assembly itself in its folded compact unit format. Weight and volume largely affects transportation, nowadays not only economically but also ecologically, in terms of footprint, the demand for continuous reduction of weight and volume has never been more active. Despite existing efforts to stack package assemblies more efficiently, there is a need to significantly increase this discrete number by adjusting or reducing the height of the package assembly. The impact of this is enormous, because even an increase of one has to be multiplied by the amount of packaging assembly stacks that can be placed side by side in the transport vehicle in two dimensions. Object of the invention The object of the invention is to provide a collapsible packaging assembly, associated pallet and lid for use in transportation, satisfying the need for effectiveness in terms of volume aspects, especially in unfolded mode, in particular by height. of this expanded mode more effective (e.g. smaller, avoiding open spaces, more compact structure) without compromising the strength requirements for the transport. Summary of the Invention Given the purpose of the packaging assembly to provide a box body for containing a product or material to be shipped or stored, considerations about the strength of the packaging assembly, especially because of its collapsible nature, are subject to adaptations. , such as the ones necessary to achieve the above purpose, are important technical considerations.

The invention relates to a packaging assembly adapted for use with a forklift truck having forks to lift the assembly. Such a packaging assembly has a (bottom) plate, wherein said plate, in erected condition, provides a bottom for the box body, said plate being made of corrugated cardboard material and thus hereinafter referred to as corrugated cardboard plate. While prior art packaging assemblies are effective in terms of strength considerations, here from the corrugated board, the requirement to have a first set of beams arranged so that forklift forks cannot enter at the position or height of this first set of beams, a negative influence on the object of the invention with regard to the considered height problem. The invention therefore provides an assembly in which the corrugated board sheet is provided with (one set of) beams, these beams being arranged to be able to insert forks of a forklift truck for lifting the assembly and these beams are directly connected to one side of the corrugated sheet (usually the side of the sheet that faces the ground, while the other side of the sheet forms the inner surface of the bottom of the box body). For clarity, a beam here (from one set) may be a solid (solid) beam or a composite of interconnected elements, while the first set of beams as referred to in the art generally require full (solid) beams. The absence of two sets of beams, and instead only one set of beams, is beneficial to the object of the invention with regard to the height problem under consideration. To be equally effective in terms of strength considerations, here of the corrugated board, the corrugated board is fitted on the opposite side from the beam side, i.e. the side of the board which forms the inner surface of the bottom of the box body with a reinforcing means attached thereto. , which creates stiffness to the corrugated board (similar to the first set of beams according to what the prior art would do). In essence, reinforcing agents, typically distributed over essentially the entire inner surface of the bottom plate (except at the boundaries as will be explained further on), provide precise utilization, because of the rigidity they are required to provide, as could reasonably be accommodated by use of a larger area as (first) beam or (first) set of beams. It is worth noting that the single set of beams in the invention can or will actually contribute to the stiffness and can be included in the calculation of the requirements imposed on the reinforcing means. For the sake of clarity, while as stated the reinforcing means is typically distributed over substantially the entire inner surface of the bottom plate (except at the boundaries), alternative embodiments where the reinforcing means may consist of several separate or connected parts, probably utilizing the presence of the remaining set of beams, possibly. The reinforcing agents do not even have to be homogeneous. As stated, in a packaging assembly, characterized in that the assembly can be folded into a compact unit and erected to provide a box body for containing a product or materials to be shipped or stored, the packaging assembly having a collapsible frame considerations about the strength of that assembly, especially because of its collapsible nature, are important technical considerations. To add strength, the assemblies comprise a lid, the lid having a top surface and four dependent sides, these sides being adapted to telescopically engage the upper outer surface of the frame when unfolded and erected into a box body. the lid providing a top sheet when the box body is erected and a top sheet for the plate and the collapsible frame when folded away.

Basically, the longer or more the dependent sides extend downward, the better the strength. However, here we are dealing with a packaging assembly, which is adapted for use with a forklift with forks to lift the assembly, wherein beams are arranged to access or permit the forks of a forklift to lift the assembly. to lift. The beams can consist of outer beams and inner beams, i.e. beams arranged along one of the edges of the slab (i.e. on the outside of the slab), or at a certain distance from it (i.e. placed closer to the center of the slab). 5, but parallel to an edge direction). According to one embodiment, all beams are arranged parallel to each other. While effective in terms of strength considerations, here of the box (folded or unfolded) in synergy with the lid with its sides, the requirement to access or allow forks of a forklift to lift the assembly imposes a hard restriction on the extension of the dependent sides downwards, in that, in particular when the folding frame is folded away and the cover forming a top or top for the plate together with this folded frame, it must not block such access .

The invention provides a solution to this problem in that, in addition to the above, the lid further has four legs (one on each corner of the lid) (each leg comprises two connected sides which can be interpreted in some way as part of the lid). dependent sides but greater in height compared to the height of the dependent sides), extending (down) beyond the dependent sides (so that the legs represent a greater height or appear longer than the dependent sides), the legs being adapted to telescopically engaging the upper outer surface of the frame when extended particularly at the top edge corners thereof, the legs being adapted to telescopically engage (and no further than that and preferably a little above the ground for reasons of humidity) with the outside of the outermost beams, specifically on the upper outside or outer corners thereof, when the shell frame is folded away. The word mantle frame is used here as it refers to the frame as a kind of mantle (side cover) for the box body when unfolded and erected. The size of the joined sides of the legs is chosen such that such access of forks of a forklift truck is not blocked. In one embodiment of the invention, the joined sides of the legs have smaller or at most comparable or the same dimensions (e.g. height, width) as the outside of the outermost beams (which helps prevent damage to the legs). As noted, although the absence of two sets of beams, and instead having only one set of beams, is beneficial for the purpose of the invention with regard to the height problem under consideration, the solution of using dependent sides of the cover to reinforcement reasons less effective the more limited the extension or height of those sides. Except for the legs, of course, and thus the solution offered by the invention to provide legs (extending beyond those sides) as described becomes more pronounced.

As mentioned above with a packaging assembly comprising a collapsible frame, considerations about the strength of the packaging assembly, especially because of its collapsible nature, are important technical considerations, and it is noted that (similar to the sides of the lid) the (bottom- or ground) plate side features that contribute to its strength, while the folded frame is more resistant to when erected.

However, the invention goes further. While the minimum height of the side flaps is there to allow the frame to be accommodated within the perimeter of the side flaps when folded, we may extend those side flaps in height above it for strength reasons. However, in order not to jeopardize the height advantages of the invention described above, the side flaps are preferably provided with horizontal (inner) fold lines, which are indicated to fold the upper part of the side flaps over the shell frame when folded. In order to further make this folding possible, the associated (higher) part of the side flaps has been adjusted in that extra fold lines have been provided.

In an embodiment thereof, of two side flaps forming a parallel pair, the related (higher) part of the side flaps is provided in its corners with a diagonal fold line. The other two side flaps (which also form a parallel pair) are extended (or extended) at that height longer than the side they need to cover the folded frame, and between the main body and the extended (or extended) part thereof is a fold line is provided, and a portion of the extension or extended portion is joined to the portion of the other side flaps created by the diagonal fold line. Note that in folded mode, essentially 4 layers of corrugated cardboard are superimposed.

As noted, although the absence of two sets of beams, and instead only one set of beams, is beneficial for the purpose of the invention with regard to the height problem under consideration, the solution of using plate side flaps for reinforcement reasons is and recording less effective the more limited the extension or height of those side flaps. The solution now offered by the invention in providing longer side flaps (optionally in combination with the lid legs) as described becomes more pronounced. It is worth noting that the side flaps protrude a certain dimension above the plate and that the thickness of the frame when folded is less than the specified dimension, more specifically that the given dimension is at least the thickness of the folded frame and the reinforcing agent applied on the bottom plate exceeds. In fact, the position of the horizontal fold lines may preferably be close to the thickness of the frame and reinforcing means.

Please note that the frame can be folded in different ways. A particularly advantageous way is one in which the frame comprises four vertical (side) panels joined together by vertical fold lines on the inside, an opposite pair of the (side panels) having vertical fold lines on the outside, allowing the shell frame to be folded with the remaining pair of (side) panels to overlay each other It is worth emphasizing that in this embodiment the above dimension (height) of the side flaps must be greater than 6 times the thickness of the frame sides (rather than of 4 times as one would expect) and the thickness of the reinforcement.

It is worth noting that the elongation of the side flaps can be significant. Essentially the limitation is only that the side flaps preferably do not touch or overlap each other when folded, otherwise the height of the assembly when unfolded will be higher and moreover more thickness would be generated which again requires more height, which we want to avoid . Finally, given the particular embodiments of folding the shell frame and/or folding the extended or extended part of the side flaps, which leads to a slightly higher height of the folded mode (albeit still considerably lower than the standing van-technique due to the removal of the first set of beams), in terms of amount of corrugated board overlap, this leaves exactly room to make the legs of the lid or cover a little longer than expected.

In summary, the invention provides a corrugated packaging assembly comprising a corrugated box body and a corrugated board sheet, characterized in that the assembly can be folded into a compact unit for transportation purposes, and can be unfolded and erected to provide a box body for containing a product or material to be being shipped or stored, the corrugated box body comprising a collapsible jacket frame, the corrugated packaging assembly adapted for use with a forklift with forks to lift the assembly, the corrugated sheet having beams adapted to allow entry of the forks of a forklift or to allow the assembly to be lifted by connecting the beams directly to a first side of the corrugated cardboard sheet, the corrugated cardboard sheet having a reinforcing means attached thereto on a second side; and/or the invention provides a corrugated packaging assembly having a corrugated box body and a corrugated board sheet, characterized in that the assembly can be folded into a compact unit for transport purposes and can be unfolded and erected to provide a box body for containing a product or materials to be transported or stored, the corrugated box body comprising a collapsible jacket frame, the corrugated packaging assembly adapted for use with a forklift truck having forks to lift the assembly, the corrugated board having beams arranged to hold the forks of a admitting or permitting a forklift to lift the assembly, the corrugated box body comprising a lid, the box body lid having a top surface and four dependent sides, the sides adapted to telescopically engage the upper outer surface ak of the shell frame when unfolded, the lid forming a top for the box body when erected (and thus shell frame unfolded), and a top for the assembly when folded away, the lid of the box body further having four legs (one on each angle) (each leg includes two joined sides), extending beyond the sides, the legs being adapted to telescopically engage the upper outer surface of the shell frame when deployed, particularly at the upper outer corners of the shell frame, wherein the legs are adapted to telescopically engage (and not beyond) the exterior of the outer beams, particularly at the outer corners of the outer beams, when the skirt frame is folded away.

Description of the drawings Figure 1 shows a packaging assembly 20 according to the invention with a lid 200, a (foldable) shell or frame 210, a structure 220 (appears as an open box) with a (bottom or base) plate 225 with side flaps 230 projecting above the plate 225. The packaging assembly 20 shown in the mode here in which the frame 210 is unfolded and erected may also be referred to as the unfolded and/or erected packaging assembly 20. The structure 220, i.e. both plate 225 and side flaps 230, as well as shell or frame 210 and cover 200 are made of corrugated cardboard.

As part of the cover 200, the top surface 245 and one of its dependent sides 205 are also shown.

As clearly shown herein, the dependent sides 205 are adapted to telescopically engage the upper outer surface of the frame 210 when unfolded and erected into a box body.

Figure 1 shows the invented feature of lid legs 240, one on each corner of the lid 200, and each lid leg 240 with two sides joined; and further showing the beams 250, here for example made of wood, directly connected to the (bottom or base) plate 225. A horizontal fold line 215 is also visible here.

With Figure 1, but also Figure 2, the coordinate system x, y, z is given.

Whenever height is referred to in the present description, the dimension along the z-axis should be taken into account, while width usually corresponds to the dimension along the y-axis, and depth would suggest moving along the x-axis.

Terms like horizontal and vertical would imply along the y-axis or z-axis respectively, while diagonal can refer to an oblique (or inclined) straight line in the yz plane.

Figure 2(a) shows a packaging assembly 30 in accordance with the invention as in Figure 1 but wherein the beams 350 (which may consist of outer beams 351 and inner beams 352) are also made of corrugated board material. Both plate 325 and side flaps 330 (which together define the structure 320 which appears as an open box) and jacket or frame 310 and cover 300 are made of corrugated cardboard material.

The lid 300, consisting of a top surface 345 and four dependent sides 305, one of which is visible, is again illustrated. Again, the dependent sides 305 are adapted to telescopically engage the upper outer surface of the frame 310 when unfolded and erected into a box body, as shown. The downward extension 365 of one of the dependent sides 305 and the lid legs 340 are illustrated. The lid 300 has four legs 340, i.e. one on each corner of the lid 300, and each leg 340 includes two connected sides that can be interpreted in some way as part of the dependent sides 305 but greater in height or downward extension 355 compared to the height or downward extension 365 of the dependent sides 305. Referring to Figure 2(b), the joined sides of the legs 340 may be smaller or at most similar or the same dimensions (e.g., height, width) as the outside of the outer beams 351 (helping to prevent damage to the legs 340). Figure 2(b) illustrates the packaging assembly 40, i.e. the situation of Figure 2(a) when the frame is not unfolded and erected. The packaging assembly 40 shown in the mode here in which the frame 310 is folded and stored in the structure 320 may also be referred to as a folded packaging assembly or compact unit 40. The thick line 360 illustrates the limit for the extension 365 of the sides 305 of the cover 300 to prevent blockage of the forks infeed. In Figure 2(a), the minimum upward extension 390 or minimum lower portion of the side flaps 330 is shown and also the additional upward extension 335 or upper portion of the side flaps 330, indicating the location of the additional horizontal fold line 315 . In Figure 2(a), the side flaps 330 typically extend completely above the plate 325 because they are unfolded, and thus the upward extension 335 is unfolded from its folded state, which can occur when the lid 300 of the compact unit 40 is opened as shown. in Figure 2(b) is removed. Referring again to Figure 2(b), the extension of the legs

340, slightly above the ground for humidity reasons, indicated by the thick dotted line 370. In a humid environment, for example with a wet ground floor, it would be preferable to use wooden beams rather than beams made of corrugated board material. Especially given their direct contact with the wet ground floor, corrugated beams in such an environment would quickly become soft and weak, ultimately leading to damaged and useless composite strength. Although wooden beams are more likely to be used on such an occasion, and with lid legs 340 not reaching the ground floor in the folded assembly mode as shown in Figure 2(b), neither the top will be weakened or damaged, allowing the assembly to retain its shape and strength . To further facilitate the folding, the related (higher) part of the side flaps 330 is adapted in that additional fold lines are provided, more particularly with two side flaps 330, forming a parallel pair, whereby the related (higher) part of the side flaps 330 is provided in its corners with a diagonal fold line 400.

Figure 3 illustrates the advantage of the invention in particular by comparing the prior art as depicted in Figure 3(a), with two embodiments of the invention shown in Figures 3(b) and (c) in relation to the height and thus the possibility to stack more of said packaging assemblies in the folded state. The first embodiment of Figure 3(b) represents packaging assemblies based on wooden beams in accordance with the invention, while the second embodiment illustrated in Figure 3(c) represents packaging assemblies made entirely of corrugated board, except perhaps for the reinforcing means 260 ( as illustrated in Figure 5) made of honeycomb cardboard. Counting the number of package assemblies for both stacks as shown in Figure 3, it becomes apparent that for approximately the same total stack height h, the prior art configuration of Figure 3(a) represents only 9 package assemblies, while both embodiments of the invention, shown in Figures 3(a) and (b), respectively, represent 12 package assemblies in accordance with the invention. Due to the height reduction of the compact unit mode of a single packaging assembly, as many as three, and thus considerably more, additional packaging assemblies can be stacked compared to the prior art, within e.g. the same shipping container or storage space. For this particular example comparison, approximately 33% more package assemblies can be stacked in accordance with the invention and compared to the prior art, for approximately the same stack height.

In particular, Figure 4 illustrates the invention by comparing a prior art packaging assembly V1 as shown in Figure 4(a) with two embodiments V2, V3 of the packaging assembly according to the invention shown in Figure 4(b) and ( c) respectively, from the perspective, showing the (bottom or base) plate 225 and the concept (wooden or corrugated board material) beams 250, 350 directly connected to the (bottom or base) plate 225. As in the prior art V1 illustration of Figure 4(a), first embodiment V2 shown in Figure 4(b) represents a wooden beam packaging assembly in accordance with the invention, while second embodiment V3 illustrated in Figure 4( c) represents a packaging assembly consisting of beams of corrugated cardboard material. It is further noted that in the prior art V1 illustration of Figure 4(a), the distinction between the first set of beams 150 and the second set of beams 450 is clearly shown with the first set of beams 150 in contact but not connected. is mounted thereon with the box structure 120 (whether or not in folded mode) and the second set of beams 450 is mounted on the first set of beams 150. Both the first and second set of beams 150, 450 are made of wood, while the box structure 120 is made of corrugated cardboard material.

Figure 5 shows a cross-section of the invented concept, wherein the (bottom or base) plate 225 (part of structure 220) is made of corrugated cardboard material, and the corrugated cardboard plate 225 is provided on one side with beams 250 directly connected thereto, while on the other side, i.e. the side of the plate 225 which forms the inner surface of the bottom of the box body with a reinforcing means 260, and especially here a honeycomb cardboard structure. In Figure 5(a), the (folding) sheath or frame 210 has not yet been assembled or provided, although arrow 270 indicates the space made available for mounting and attachment of the sheath or frame 210 when unfolded and is established in the assembly. In Figure 5(b), the unfolded shell or frame 210 is erected, and mounting or attachment thereof to the bottom of the plate 225 is clearly visualized here. Thus, Figures 5(a) and (b) illustrate that said reinforcing means 260 is preferably sized so that when the shell or frame 210 is unfolded to be assembled, the shell or frame 210 will at the same time removably fit the outer periphery (or the outer edge) of said reinforcing means 260 and the inner or inner surface of the side flaps 230 of the structure 220 during the erection of the corrugated packaging assembly. In addition, as indicated by arrow 270, between the outer edge of reinforcing means 260 and the inner surface of the side flaps is such that the shell or frame 210 can be secured therein, and a sturdier or more rigid construction of the assembly is achieved when it is mounted. set up. According to a particular embodiment of the invention, the beams 250 can be connected directly to one side of the corrugated board 225 and/or the reinforcing means 260. As shown in Figure B(c), the top of the beam part is connected to the reinforcing means 260, here especially made of honeycomb. Thus, a hole is cut in the corrugated board 225 to pass through the top of the beam member and be joined to the underside of the reinforcing means 260. Because of this, through the plate 225, one could also say that the beams 250 are directly connected to both the plate 225 and the reinforcing means 260.

Figure 6 illustrates with Figure 6(a) the stacking of the packaging assembly when folded, with Figure 6(b) the use of the unfolded carton assembly with its lid or cover and with Figure 6(c) the use when the shell or frame is folded and the lid or cover acts as a top when the shell or frame is folded away. Referring to Figure 7, an embodiment of the invention is shown illustrating the side flaps. Here, two side flaps 321, 322 form a parallel pair, and the related (higher) portion 335 of the side flaps 321, 322 is provided in its corners with a diagonal fold line 400. The other two side flaps 323 (also forming a parallel pair, but one not shown) are extended with extension 356 at that height longer than the side they need to cover the folded frame 310, and between the main part 790 and the extended part 735 there is provided a fold line 715, and part of the extension 356 or extended portion is joined (here even stitched 780) to the triangular portion of the other side flaps 321, 322 created by the diagonal fold line 400. Note that here in folded mode, essentially 4 layers of corrugated cardboard are superimposed.

Referring to Figure 8, an embodiment of the invention is shown which illustrates that the frame 810 can be folded in various ways. A particularly favorable manner is one where the frame comprises four vertical (side) panels 811, 812, 813, 814 interconnected by vertical fold lines 821, 822, 823, 824 on the inside, wherein an opposing pair of the (side) panels 812, 814 with vertical fold lines 831, 832 on the outside, allows the shell frame to fold with the remaining pair of (side) panels 811, 813 to overlie each other. By vertical is meant here, along the z-axis when the frame is unfolded and erected. In the case of Figure 8, the z-axis comes from the xy plane of the drawing. It is worth emphasizing that in this embodiment the minimum dimension, i.e. height or extension of the side flaps, must be greater than 6 times the thickness of the frame sides (instead of 4 times as one would expect) and the thickness of the strengthening agent. Description of the invention To further illustrate the advantage of the invention, in particular when comparing a prior art packaging assembly V1, with the two embodiments V2, V3 of the packaging assembly according to the invention, with regard to the height and thus the possibility to stack more of said packaging assemblies, the following table is considered: LE Bessarins V1 303 It should be noted that the numbers in the table above are given as examples and are therefore not limited thereto. The example numbers above are particularly used to indicate the positive impact of the invention in the case of concrete embodiments V2, V3 compared with the prior art V1. As already described in the example comparison with Figure 3, the number of assemblies to be stacked can increase from 9 to 12, which leads to a transport increase of pallets per truck (or truck) from 234 to 312, i.e. 25%. As a result, the required number of trucks per year for the same amount of pallets per year can be reduced by 25%.

Recalling again that with the invention the beams 250, 350 are directly connected to the plate 225, 325 as shown in Figures 1 and 2, only one set of beams instead of two is used as compared to the prior art. In particular, the first set of beams 150 of the prior art configuration V1 as shown in Figure 4(a) is now eliminated or excluded with the invention. As a result, less wood and therefore less weight is present in the invention, even taking into account extra weight caused by the reinforcing means 260 applied to (the inner surface of) the bottom of the structure 220. Particularly here 25% less weight is obtained with the embodiment V2 with a remaining set of wooden beams as opposed to the prior art configuration V1. In addition, considering the embodiment V3 where the beams are made of corrugated cardboard material instead of wood, the weight can be reduced even further, up to as much as 40% less compared to the prior art.

The invention is as claimed and illustrated by Figures 1 to 6 discussed above and essentially provides: A corrugated cardboard packaging assembly 20, 30 having a corrugated box body and a corrugated box 220, 320, characterized in that the assembly 20, 30 can be folded into a compact unit 40 and can be erected to provide a box body for containing a product or material to be shipped or stored, the corrugated box body comprising a collapsible jacket frame 210, 310, the corrugated packaging assembly 20, 30 being adapted for use with a forklift with forks to lift the assembly 20, 30, said corrugated carton 220, 230, comprising a corrugated board 225, 325, being provided with beams 250, 350 arranged to access or allow access to the forks of a forklift to allow for lifting the assembly 20, 30, by directly connecting the beams 250, 350 to a first side of the corrugated board 225, 325; and wherein the corrugated board 225, 325 is provided on its second side with a reinforcement 260 attached thereto; and/or a corrugated packaging assembly 20, 30 having a corrugated box body and a corrugated board 225, 325, characterized in that the assembly 20, 30 can be folded into a compact unit 40 and erected to provide a box body for containing a product or material to be shipped or stored, the corrugated box body comprising a collapsible jacket frame 210, 310, the corrugated packaging assembly 20, 30 being adapted for use with a forklift truck having forks to lift the assembly 20, 30, said corrugated board 225, 325 provided with beams 250, 350 arranged to allow or access the forks of a forklift truck for lifting the assembly 20, 30, to thereby provide pallet functionality, by directly connecting the beams 250, 350 to a first side of the corrugated board 225, 325; and wherein the corrugated board 225, 325 is provided on its second side with a reinforcement 260 attached thereto.
