Description

Flattenable volume-optimized packaging

The invention relates to a flattenable volume-optimized packaging material, preferably made of corrugated cardboard, having a prism-shaped layout according to the preamble of claim 1.

From European Patent Publication EP 1 225 130 A1, an octagonal folding packaging made of corrugated cardboard according to the preamble of claim 1 is known, by which heavy and extremely heavy articles can be transported reliably. For example, the two side wall sections to be arranged along the longitudinal sides of the rectangular pallet may be longer than the remaining six side wall sections to ensure optimal utilization of the available space on the pallet.

However, increasingly, there is a need to transport very heavy items as well as lighter items in such collapsible or flattenable packaging materials as cost-effectively as possible. For this purpose, it is essential to be able to accommodate as large a volume as possible within such packaging. Additionally, it should also be possible to produce such packaging with a wide range of geometries, in particular with different and possibly as diverse ratios of the lengths of the individual side wall parts to each other, which are advantageous for achieving the highest possible volume. At the same time, for transport to the point of use, such packaging must be able to be folded into a flat state as small as possible and unfolded reliably and quickly at the point of use, without requiring complex handling.

Also known are octagonal folding packaging materials made of corrugated cardboard according to the preamble of claim 1 from European Patent Publication EP 3 489 160 A1. In embodiments with a regular octagonal layout, each bottom portion has a single fold line for the required folding operation. In order to be able to carry out the required folding process even in the case of irregular, i.e. asymmetrical, layouts, two additional oblique fold lines are provided to compensate for the "skew" angle caused by the irregularities. , in another embodiment provided within the two largest bottom portions.

The object of the present invention is to provide individual side wall sections that have as large a volume as possible and that can be folded together, transported, unfolded without any assembly assistance, dimensionally stable, and with mechanical support at reasonable cost. The aim is to provide a levelable packaging material that can be produced with different ratios of its lengths to each other.

According to the present invention, this object can be achieved by the packaging material set forth in claim 1. Further advantageous developments of the invention are the subject of the dependent claims.

According to the invention, a flattenable volume-optimized packaging, preferably made of corrugated cardboard, having a prism-shaped layout, preferably formed from a single member, comprising at least eight interconnected side wall parts, joined to form a ring, formed of at least eight interconnected side wall portions, two of whose side wall portions are individually essentially parallel to each other and have equal side lengths, and as a first bottom portion and a second bottom portion, essentially It is formed of a first bottom portion and a second bottom portion, which can be aligned perpendicularly to the side wall portions and can be folded between the side wall portions and are each hinged to two side wall portions. The invention provides a device wherein two bottom portions each have three fold lines, whereby the bottom portions can be folded between the side wall portions, at least in certain sections thereof, into four layers. It is characterized by According to one variant, the two bottom parts cover the entire bottom area of the packaging, as described in a similar way in German Patent Publication DE 10 2019 004 490.8, but are hinged on only four out of a total of eight side wall parts. Connecting is possible.

This creates a packaging material with a very large volume (relative to the surface area defined by its outer contour), since it can be flattened and, above all, has a large degree of freedom in the selection of the length of the individual side wall sections. In addition, the packaging material according to the invention can be transported in a small folded state and, due to the triple folding by three fold lines, automatically and thereby passively assists when pressure is applied to the two opposing lateral edges. Since it unfolds without any assembly assistance, it can be unfolded without any assembly assistance. However, at the same time, the packaging material according to the invention is dimensionally stable and can be produced with mechanical support at low cost.

According to various embodiments, the foldability of the packaging material according to the present invention can be improved by various measures. This is possible, above all, when three folding lines are formed by two counter-grooves and one main groove between the counter-grooves. A further improvement is obtained if the main groove of the first bottom part is parallel to the main groove of the second bottom part. Additionally, this means that the first bottom portion and the second bottom portion are at least essentially point-symmetrical with respect to each other, and the first counter-groove of the first bottom portion is parallel to the first counter-groove of the second bottom portion. And it may be advantageous if the second counter-groove of the first bottom part is parallel to the second counter-groove of the second bottom part.

In an advantageous embodiment, a third bottom portion and a fourth bottom portion are provided, each having a fold line, wherein the first bottom portion is hinged to the first side wall portion and the fourth side wall portion, and the second bottom portion is hinged to the first side wall portion and the fourth side wall portion. The bottom portion is hinged to the fifth side wall portion and the eighth side wall portion, the third bottom portion is hinged to the second side wall portion and the third side wall portion adjacent the second side wall portion, and the fourth bottom portion is hinged to the second side wall portion and the third side wall portion adjacent the second side wall portion. , is hingedly connected to the sixth side wall portion and the seventh side wall portion adjacent to the sixth side wall portion. This embodiment with four bottom parts is particularly easy to manufacture and is very easy to unfold. The four bottom portions are each connected or hinged to two side wall portions, and thus there are no side wall portions that do not have a connection to the bottom portions, and in addition the packaging material according to the invention is very stable. am.

The foldability of the above-mentioned embodiment is further achieved when the main groove and the second counter-groove of the first bottom portion are not only parallel to each other, but also are parallel to the main groove and the second counter-groove of the second bottom portion. It can be improved.

In another advantageous embodiment, there is provided a third bottom portion and a fourth bottom portion each having a fold line, and a fifth bottom portion having three fold lines, wherein the third bottom portion comprises a second side wall. hinged to the portion and to a first section of the third side wall portion, the first section being adjacent to the second side wall portion; the first bottom portion is hinged to the first side wall portion and to the second section of the third side wall portion; the fourth bottom portion is hinged to the sixth side wall portion and to a first section of the seventh side wall portion, the first section adjacent the sixth side wall portion; the second bottom portion is hinged to the fifth side wall portion and to the second section of the seventh side wall portion; And the fifth bottom portion is hinged to the fourth side wall portion and to an eighth side wall portion located diagonally opposite the fourth side wall portion. The individual first and second sections of the third and seventh side wall portions do not necessarily have to occupy the entire length of those side wall portions. This embodiment with five bottom parts is also very easy to unfold. Each of the five bottom parts is connected or hinged to two side wall parts, and thus there are no side wall parts that do not have a connection to the bottom parts, and in addition, the packaging material according to the invention is very stable. am. The stability is provided by the fact that the fifth bottom portion is connected to diagonally opposite side wall portions, and that two of the side wall portions (in a separate first section) are connected via the bottom portion to adjacent side wall portions, as well as to separate second wall portions. In sections, these are further improved by the fact that they can also be connected to the “one-over-next” side wall part via another bottom part.

The foldability of the above-mentioned embodiments can be further improved by appropriate design of the individual fold lines. This design option is such that the three fold lines of the fifth bottom part are formed by two counter-grooves and a main groove located between the counter-grooves, and the main groove of the fifth bottom part and the first counter-groove are , which are not only parallel to each other but also parallel to the main groove of the first bottom portion and to the main groove of the second bottom portion; a second counter-groove of the fifth bottom portion is parallel to the two side wall portions; and/or the fold line of the third bottom portion and the fold line of the fourth bottom portion are, respectively, angle bisectors between the second side wall portion and the third side wall portion and between the sixth side wall portion and the seventh side wall portion. Including those located on the

The expression “at least essentially point-symmetrical” means that the exact point symmetry of the arrangement of the side wall portions and/or bottom portions is not critical, but that, for example, their individual angles relative to neighboring or adjacent side wall portions are This means that it is designed so that it can be flattened and unfolded again without any problems. Thus, for example, one or more side wall portions can be designed in a multi-part or rounded manner, without corresponding point symmetry "on one side" and "on the other side".

When the packaging according to the invention is laid flat or leveled, it can be unfolded, generally without any further handling, by simply pressing together the two opposing edges on which the fold lines are located. For this purpose, it is understood that the individual bottom parts must be suitably designed and hinged to the associated side wall parts.

1a and 1b show two embodiments of individual rings 20 of packaging material 10 according to the invention. In the embodiment of Figure 1A, two long side wall parts 21 and 25, two medium-length side wall parts 23 and 27, and four short side wall parts, for example corresponding to the standard type CP 1. (22, 24, 26 and 28) are provided. In the embodiment of Figure 1b, on the other hand, four long side wall parts 21, 23, 25 and 27 of equal length, for example corresponding to the standard type CP 3, and also four short side wall parts of equal length. (22, 24, 26 and 28) are provided. In both embodiments, a small side wall portion 29 is also attached to the side wall portion 24 such that it connects to the side wall portion 25 to close the ring 20.

Figures 2a and 2b schematically show top views of two variants of the first embodiment of unfolded packaging materials 10 according to the invention, with an octagonal layout or plan view. In this first embodiment, four bottom parts 31 to 34 are provided, the two larger bottom parts 31 and 32 being point-symmetrical to each other about the center of the layout of the packaging material 10, and The two smaller bottom portions 33 and 34 are also point-symmetrical with respect to each other. It will be appreciated that minor deviations from strict point symmetry, such as that required to mutually lock two adjacent bottom portions, may exist, as long as they do not affect the foldability of the bottom portions. For simplicity, the side wall parts 21 to 28 are not shown, but instead only the surface areas, on which these side wall parts will be located, are indicated with individual reference signs, and thus they are, as will be explained later, at the bottom. It can be connected to the individual bottom tabs A to D of the parts 31 to 34.

In the variant of Figure 2A, the two side wall portions 21, 25 are each longer than the two other (medium or mid-length) side wall portions 23, 27, and these four side wall portions are longer than the remaining 4 Longer than the lateral wall segments (22, 24, 26 and 28). This aspect ratio is typical for the standard CP 1 format (1200 mm x 1000 mm). In the variant of Figure 2b, each of the four side wall portions 21, 23, 25 and 27 is longer than the remaining four side wall portions 22, 24, 26 and 28. This aspect ratio is typical for the standard CP 3 format (1140 mm x 1140 mm).

The bottom portions 31 to 34, delimited by thick continuous lines, are shown in each case so that they are adjacent to each other in a seamless manner. However, the bottom parts can also be overlapped, or narrower from one side wall part to the next, if tightness of the bottom is not required and a corresponding reduction in the stability of the packaging is acceptable, or It may be tapered only between the side wall portions. Groove lines or fold lines or fold lines that enable folding of the bottom portions are shown, in each case, as thin continuous lines. The center or midpoint of the layout of the packaging material 10 is indicated by the reference symbol 'M'. A thin continuous double line indicates the areas where the individual side wall parts are to be placed and the corresponding bottom tabs of the bottom parts can be glued or fastened thereto. These general drawing aspects apply to all drawings unless explicitly stated otherwise.

Referring to Figure 2a, a first embodiment of packaging material 10 according to the present invention has two neighboring or adjacent bottom portions 31 and 32. The first bottom part 31 is hingedly connected to the first side wall part 21 by a bottom tab C and to the fourth side wall part 24 by a bottom tab D. The second bottom part 32, arranged point-symmetrically to the first bottom part 31, is connected to the fifth side wall part 25 by the bottom tab C and to the eighth side wall part 25 by the bottom tab D. It is hingedly connected to the side wall portion (28). The third bottom part 33, which is significantly smaller, is hinged to the second side wall part 22 and to the third side wall part 23 by bottom tabs A and B, respectively. The fourth bottom part 34, arranged point-symmetrically on the third bottom part 33, is connected to the sixth side wall part 26 and the seventh side wall part (26) by means of bottom tabs A and B, respectively. 27) is hinged.

The third bottom part 33 has a fold line 36 and the fourth bottom part 34 has a fold line 37 . The two fold lines 36 and 37 are located, respectively, along the angle bisector between the side wall portions 22 and 23 (26 and 27) to which the bottom tabs A and B are attached. The first bottom part 31 has three fold lines 71 to 73, and the second bottom part 32 has three fold lines 74 to 76. Here, the two fold lines 72 and 75 are the main grooves, respectively, and the respective pairs of fold lines 71 and 73 (74 and 76) are the associated counters for the main grooves 72 and 75, respectively. These are the grooves. The counter-grooves 71 and 74 and the two fold lines 36 and 37 are parallel to each other. Additionally, the two main grooves 72 and 75 and the two counter-grooves 73 and 76 are parallel to each other. With this arrangement, the packaging 10 can be folded along a line extending between the individual bottom tabs A and B. It is understood that in this folding, a four-layer arrangement of the first bottom part 31 and the second bottom part 32 is obtained in certain regions or zones. Such packaging 10 is very flexible with respect to possible configurations for different lengths of the side wall parts 21 to 28 and the associated bottom parts 31 to 34, and thus to many different configurations for the packaging 10. It can be confirmed that the design is acceptable.

Such packaging materials make it possible to achieve optimal use of rectangular storage areas, such as pallets, as they can have larger volumes than packaging materials known from the prior art.

The above similarly applies to the packaging 10 shown in Figure 2b, where the "long" side wall portions 21 and 25 and the "mid-length" side wall portions 23 and 27 are of equal length. Such packaging materials make it possible to achieve optimal use of square storage areas, such as pallets, as they can have larger volumes than packaging materials known from the prior art.

In what follows, parts having the same reference numerals are parts having the same or equivalent function. Unless expressly stated otherwise, the above statements also apply to the embodiments and variations described below.

3a and 3b schematically show top views of two variants of the second embodiment of unfolded packaging materials 10 according to the invention, with an octagonal layout. In this second embodiment, five bottom portions 41 to 45 are provided, the two larger bottom portions 41 and 42 being point-symmetrical to each other about the center of the layout of the packaging material 10, and The two smaller bottom portions 43 and 44 are also point-symmetrical with respect to each other. The fifth bottom portion 45 extends diagonally across the layout of the packaging material 10 . In a similar way as in Figure 2a, this layout corresponds to the standard CP 1 format.

In this second embodiment of the packaging 10 according to the invention, the third bottom part 43 is connected to the second side wall part 22 by the bottom tab A and to the third side wall part 22 by the bottom tab B. It is hinged to a first section 23a of the side wall portion 23, the first section 23a lying adjacent to the second side wall portion 22. Similarly, the fourth bottom portion 44 is attached to the sixth side wall portion 26 by the bottom tab A and to the first section 27a of the seventh side wall portion 27 by the bottom tab B. Hinged, the first section 27a lies adjacent to the sixth side wall portion 26. The first bottom part 41 is hinged to the first side wall part 21 by a bottom tab C and to the second section 23b of the third side wall part 23 by a bottom tab D. . Similarly, the second bottom portion 42 is attached to the fifth side wall portion 21 by a bottom tab C and to the second section 27b of the seventh side wall portion 27 by a bottom tab D. It is hinged. According to the example of Figure 3A, the sum of the lengths of the bottom tabs B and D is equal to the respective lengths of the side wall portions 23 and 27, but the sum may also be less than the respective lengths. The fifth bottom portion 45 is hinged to the side wall portion 24 by a bottom tab E and to the side wall portion 28 by a bottom tab F, and the eighth side wall portion 28 is connected to the side wall portion 24 by a bottom tab E. It lies diagonally opposite to portion 24.

The third bottom part 43 has a fold line 46 and the fourth bottom part 44 has a fold line 47 . The two fold lines 46 and 47 are located, respectively, along the angle bisector between the side wall portions 22 and 23 (26 and 27) to which the bottom tabs A and B are attached. The first bottom part 41 has three fold lines 81 to 83, and the second bottom part 42 has three fold lines 84 to 86. The fifth bottom portion 45 has three fold lines 87 to 89. Here, the three fold lines 82, 85 and 88 are, respectively, main grooves, and individual pairs of fold lines 81, 83, 84, 86, 87, 89 are, respectively, main grooves 82. , 85 and 88) are the associated counter-homes. The three main grooves 82, 85 and 88 and the counter grooves 87 are parallel to each other, and the four counter grooves 81, 83, 84 and 86 are also parallel to each other. Additionally, the two fold lines 46 and 47 are parallel to each other. With this arrangement, the packaging 10 can be folded along a line extending between the individual bottom tabs A and B. It is understood that this folding also achieves a regional four-layer arrangement of the first bottom part 41 , the second bottom part 42 and the fifth bottom part 45 . Such packaging 10 is also very flexible with respect to possible designs for different lengths of the side wall portions 21 to 28 and the associated bottom portions 41 to 45, thus providing many options for the packaging material 10. It can be seen that this allows for different designs.

The above similarly applies to the packaging 10 shown in FIG. 3B , where the “long” side wall portions 21 and 25 and the “mid-length” side wall portions 23 and 27 are of equal length. Similar to the embodiments described in Figures 2a/2b, such packaging materials are configured in a rectangular or square manner, such as pallets, as they can have larger volumes than packaging materials known from the prior art. Optimal use of available storage areas can be achieved.

Figure 4a shows an exploded view of a specific embodiment of the first embodiment illustrated in Figure 2a, which has four bottom parts 31 to 34. Figure 4b shows a top view of the interlocking bottom parts 31 to 34, corresponding to an internal view of the packaging material 10. Figure 4c shows a bottom view of the interlocking bottom parts 31 to 34, corresponding to the external view of the packaging material 10.

Figure 6b shows an internal view of the rear side of the unfolded packaging 10 of Figure 6a, while Figure 6d shows an external view of the front side of the unfolded packaging 10 of Figure 6a, both Figures 6b and 6d. In, the bottom tabs A to D are attached to the respective side wall portions 21 to 28. Figure 6c shows a top view of the folded packaging 10 of Figure 6a, in which bottom tabs A to D are shown protruding from side wall portions, which are not individually shown here for clarity.

FIGS. 7A to 7D correspond to FIGS. 6A to 6D and refer to a variation of the first embodiment shown in FIG. 2B. The explanation regarding FIGS. 6A to 6D applies accordingly.

8a to 8d and 9a to 9d correspond to two variants of the second embodiment shown in FIGS. 3a and 3b, respectively dealing with bottom tabs A to F. The explanation regarding FIGS. 6A to 6D similarly applies.

Figures 10a and 10b show, individually, various folded states, starting from the view immediately after punching (and inserting the grooves) up to a folded state in which the bottom portion can be glued between the corresponding side wall portions. , shows the second bottom part 32 and the fourth bottom part 34 of the first embodiment. Figures 11a, 11b and 11c show, respectively, various folded states, starting from the view immediately after punching (and insertion of the grooves) up to the folded state in which the bottom part can be glued between the corresponding side wall parts. shows the fifth bottom portion 45, the second bottom portion 42 and the fourth bottom portion 44 of the second embodiment. It is understood that the order of the folding steps in FIGS. 10A , 11A and 11B may differ from the order shown.

12a to 12c show an overview of various design options for the angular and aspect ratios of packaging materials according to the invention, while FIG. 12a shows in an exemplary manner a second embodiment of the standard types CP 1 and CP 3. and Figure 12b shows in an exemplary manner a first embodiment of the standard format CP 1 and CP 3, and Figure 12c shows in an equally exemplary manner a first embodiment of the channel format (1200 mm x 800 mm). It is shown as It goes without saying that individual embodiments may consist of even more elongated rectangles with corresponding angular arrangements.

The above embodiments and their variants can be produced with precisely indicated aspect ratios and angle ratios of the bottom parts and of the side wall parts with their individual fold lines. However, independently of the individual size ratios, it is of course possible to make large changes to these aspect and angle ratios.

It should be noted that the bottom portions shown above can each be designed to overlap each other, as is generally known. Additionally, they may be equipped with suitable slots and configurations to allow mutual locking (and, if necessary, unlocking) in the unfolded state.

In the preceding description, it was assumed that the packaging material was produced from corrugated cardboard. However, it may also be made of different materials, such as paper or plastic materials.

It should be noted that due to the inherently given point symmetry of the sidewall portions about the central point, there are only an even number of sidewall portions. Correspondingly, the invention also includes packaging materials having 10, 12 or even more side wall portions. However, as mentioned above, point symmetry can also be canceled with respect to points, in that, for example, a single side wall section has a rounded structure or the like.

Features of the invention described with reference to individual embodiments, such as bottom portions and bottom tabs, side wall portions, side wall portion sections, and fold lines, are also provided unless otherwise indicated or automatically prohibited for technical reasons. , may be presented in other embodiments. With respect to those features of individual embodiments being described in combination, additionally, not necessarily all features must always be implemented in the individual embodiments.
