Description

The present invention relates to a package, preferably of corrugated cardboard, with an octagonal outline, where n is a positive integer ≥ 3.

Corrugated board packaging is increasingly being used to package heavy and heaviest goods. For example, plastic granulate packages have to withstand high loads due to the high mass of units transported on a pallet. On the one hand, on the one hand, hard-wearing plastic bags are frequently used, on the other hand, for cost and environmental reasons, attempts are made to use as little plastic as possible and to replace such high-load bags with corrugated board packaging.

Such a package is from the EP 1 225 130 A1 known. This foldable packaging is very stable. However, it has been found that this packaging tends to be "round" in the upper or middle region immediately above the attachment of the floor parts at very large loads or loads, so they no longer has the optimum strength and more vulnerable in this area for tearing or tearing of the packaging material.

The present invention has for its object to provide a package that is even more resistant to tearing or tearing of the packaging material and beyond machine-assisted can be produced inexpensively.

This object is achieved with a package according to claim 1 or claim 9. Advantageous developments of the invention are the subject of the dependent claims.

Of particular interest to the understanding of the present invention is that portion of the package which extends from the bottom thereof upwardly beyond the retaining tabs, for example to a height of twice the height of the retaining tabs.

For ease of explanation, for the sake of simplicity, it is assumed that a package has a bottom which is arranged "below" or forms the underside of the package, and that a lid "top" - so on the top - placed on the packaging can be. Thus, the terms "bottom" and "top" refer to the respective ends of the package regardless of how it is placed or disposed in the exact space. Statements such as "right" and "left" refer to a vertical view of the drawing plane.

According to the invention, according to a first aspect, a package with an octagonal outline, where n is a positive integer ≥ 3, is preferably formed from corrugated cardboard. It comprises n interconnected, preferably single-piece, side wall portions (often referred to as "rings") and a bottom substantially perpendicular to the sidewall portions, at least one, preferably at least n / 2, of the sidewall portions at its end Floor facing, lower, end portion is firmly connected to a corresponding retaining tab of the soil. The packaging according to the invention is characterized in that in the lower end portion of at least one fixedly connected side wall part at least one weakening section, which promotes the deformation behavior with respect to adjacent areas of the relevant side wall part, is provided. By the term "deformation behavior with respect to adjacent areas of the respective side wall part" is meant that the side wall part at the point where the weakening section is located, can deform / bend more easily than in the adjacent areas where the relevant side wall part " normal ", d. H. is as it is, for example, in the area of the lid or in the middle of the side wall part of the case. According to this illustration, the weakening section is thus an area of the side wall part which is located in the vicinity of e.g. B. a punched or indentation or a crimped portion and thus causes an improvement of the deformation behavior by the presence of the indentation or crimped portion. However, it can also be assumed that the weakening section does not adjoin the indentation or crimped section, but rather is formed by the cutout or indentation itself, that is to say an area within the outline of the side wall part, as would be configured without the indentation being present. and that thus in the weakening section no material or weakened - is, for example, crushed - material.

Because at least one weakening section is provided on the underside of at least one fixedly connected side wall part, the respective side wall part can also "round out" in the lower region of the packaging, without causing tearing or even tearing of the side wall part or a corresponding retaining tab of the bottom - comes. As a result, the overall stability of the packaging according to the invention is significantly improved. Thus, in the present invention compared to the previous approach in the stabilization of a package the exact opposite has been done by not reinforcing an area with material reinforcements, beads or folds as before, but weakening the area in question to achieve better ductility and thereby prevent material destruction by tearing or tearing.

According to one embodiment of the present invention, each weakening section adjoins a recess extending from the lower edge of the lower end section, ie is adjacent to this indentation. In other words, the lower end portion of the side wall portion on no continuous straight edge, but is recessed from below or provided with a downwardly open recess.

Advantageously, the indentation extends to a distance of at least 1 mm, preferably at least 5 mm, from the lower edge (more precisely from the lower edge of the side wall part, as would be formed if the indentation were not provided) of the respective side wall part away, wherein on at least one of the circumferential direction of the side wall portion related end of the respective end portion remains a web whose lower end forms the sole segment of the lower end portion a support surface for resting on the corresponding bottom. In other words, therefore, at least one of the fixedly connected side wall parts on at least one side of each indentation has a portion which can be supported on the bottom of the packaging. As a result of this configuration of the indentation, the lower part of the side wall part obtains a very good flexibility and deformability not only at the lower edge of the side wall part, but also in a substantial region in the direction away from the ground.

According to one embodiment, each recess extends over at least half, preferably at least 2/3, and more preferably at least 4/5, of the side length of the lower end portion. As a result of this configuration of the indentation, the lower part of the side wall part also obtains good flexibility and deformability in the circumferential direction of the packaging.

According to a further embodiment, each indent extends farther away from the lower edge in its center, which is related to the circumferential direction of the side wall parts, than at its edges, which are related to the circumferential direction of the side wall parts. As a result, the side wall part in the middle is better deformable than at its edges, since the correspondingly shaped indentation in the middle protrudes further upwards than at their edges.

A tearing of the underside of the side wall portion can be prevented even more reliable when the adjoining the lower edge boundary line of each indentation is rounded.

According to a further embodiment, each weakening section comprises a material crushing of the respective side wall part in a direction perpendicular to the main surface thereof, and additionally or alternatively, each weakening section comprises at least one section of reduced wall thickness.

According to another embodiment, each weakening section comprises at least one hole and / or a slot and / or a cut passing through the corresponding side wall part in its main surface. In other words, in this embodiment, the side wall part is provided with a hole, a slot or a cut and thereby weakened, which is why it is better deformable in this area than in the rest of the side wall. A further improvement of the deformability can be achieved if a multiplicity of holes and / or slits and / or cuts passing through the corresponding side wall part in the main surface thereof are provided distributed over the weakening section.

According to the invention, according to a second aspect, a package with an octagonal outline, where n is a positive integer ≥ 3, is preferably formed from corrugated cardboard. It comprises n interconnected, preferably single-piece, side wall portions (often referred to as "rings") and a bottom substantially perpendicular to the sidewall portions, at least one, preferably at least n / 2, of the sidewall portions at its end Bottom-facing, lower, end portion is fixedly connected to a corresponding retaining tab of the bottom and the lower end portions of each side wall portion having a respective lower edge. The packaging according to the invention is characterized in that the lower edge of the lower end portion of at least one fixed side wall part at a distance of at least 1 mm, preferably at least 5 mm, is fixed from the bottom of the corresponding foldable retaining tab. In other words, the ring (ie, the side wall parts) is attached to the bottom so that the bottom edge of the ring or at least the bottom edge of the respective fixed side wall parts at a distance of at least 1 mm, preferably at least 5 mm from the ground with the corresponding retaining tabs is firmly connected. The fact that at least the firmly connected side wall parts are not mounted directly on the ground seated on the retaining tabs, but a have a corresponding distance from the ground, they can better round out or deform and prevent them from being torn or even torn at a corresponding load and resulting deformation.

A foldable variant of the above inventive packaging is also possible. It is characterized in that n is even, preferably ≥ 4, of the side wall parts in each case two side wall parts are substantially parallel to each other and in the circumferential direction of the package have the same side length, and the bottom at least one of the side wall parts substantially vertically alignable foldable Bottom part, often at least two and preferably n / 2 separate, to the side wall parts substantially vertically alignable foldable bottom parts, each sidewall part is fixedly connected at its the bottom part, the lower end portion with a corresponding foldable retaining tab of the corresponding bottom part.

The deformability of the ring can be even more improved in the aforementioned embodiments, if in each case one weakening section is provided in more than one of the fixedly connected side wall parts, for example in every second of the firmly connected side wall parts. It is understood that in general a maximum deformability of the ring can be achieved if all of the side wall parts fixedly connected to a corresponding folding retaining tab have a weakening section.

From the above description it is also apparent that the respective weakening sections can each be formed in a simple manner, for example by punching or squeezing, and thus without great technical effort in the production of the packaging according to the invention, which enables the production in a simple and cost-effective manner.

Further advantages, features and special features of the invention will become apparent from the following description of preferred, but not limiting embodiments of the invention with reference to the schematic and not to scale drawings. Show it:

10 By way of example, another form of two-part bottom parts, as they can be used for a foldable variant of the packaging according to the invention.

1 shows a first embodiment of an inside of a side wall part 21 a packaging according to the invention. The side wall part 21 is with its lower end section 31 , which faces a floor, not shown here, on a retaining tab 11h attached to this floor. The approximate - ie not exactly defined - upper end of the lower end section 31 is indicated by a dashed line. Typically, the retention tabs of the floor are outboard of the sidewall portions in a fully manufactured package. Although the retaining tab 11h In this illustration, therefore, would not be visible, the upper boundary line is shown in solid, wherein the present invention is not limited to this embodiment. At the bottom of the lower end section 31 is a boundary line 31k indicated, which can also be considered as the upper edge of the floor on which the side wall part 21 rests.

Starting from the lower edge 31k of the lower end portion 31 is one through a boundary line 41b defined recess or indentation 41 provided in which the material of Side wall 21 is removed. This material removal is adjacent to the indentation 41 a weakening section 41s formed whose extent is not exactly defined and whose limitation is therefore indicated only by a dashed line. As soon as such a configured packaging is loaded, such a side wall part can 21 Round out or bulge perpendicular to the plane of the drawing (see also 6 ). How out 1 it can be seen, the indentation needs 41 not necessarily symmetrical with respect to the circumferential direction of the side wall part 21 be. How to continue 1 it can be seen, the indentation needs 41 also not in the middle of the side wall part 21 or in its lower end portion 31 with respect to the circumferential direction of the side wall part 21 be. According to the in 1 shown first embodiment remains rather on the left edge of the lower end portion 31 a footbridge 51 , with the lower edge of the side wall part 21 is supported on the bottom, not shown. In this first embodiment, the indentation extends 41 to the right edge of the lower end section 31 ,

2 shows a second embodiment of a side wall part 22 a packaging according to the invention. In 2 Similar reference numerals have been used as in 1 , where in each case the numeral 2 instead of the digit 1 out 1 at the "Einserstelle" the reference number was used. The difference from the first embodiment is that the indentation 42 and the corresponding weakening section 42s with respect to the circumferential direction of the side wall part 22 is arranged symmetrically and centrally, but not as far up or away from the ground as in the first embodiment.

Thus, each remain at the left end and the right end of a web 52 with which the side wall part 22 is supported on the bottom, not shown. In addition, the two bridges 52 rounded at its bottom, so that also the boundary line 42b the dent 42 is rounded.

3 shows a third embodiment of a side wall part 23 a packaging according to the invention. In 3 Similar reference numerals have been used as in 1 , where in each case the numeral 3 instead of the digit 1 out 1 at the "Einserstelle" the reference number was used. The difference from the second embodiment is that the indentation 43 as a rectangle with adjacent weakening section 43s is configured and thus the two webs 53 also have a rectangular shape and are not rounded.

4 shows a fourth embodiment of a side wall part 24 a packaging according to the invention. In 4 For similar elements, like reference numerals have been used as in FIG 1 , where in each case the numeral 4 instead of the digit 1 out 1 at the "Einserstelle" the reference number was used. The difference from the preceding embodiments lies in the fact that none of the aforementioned indentations form the weakening section 41 - 43 is provided, but that the weakening of the side wall and thus their better deformability is achieved by making holes 44p and / or slits 44z and / or cuts 44t , each one the lower end section 34 prevail with respect to its major surface, in the lower end portion 34 of the side wall part 24 are provided.

5 shows an octagonal bottom 16 with corresponding retaining tabs 11h to 18h to which the respective side wall parts 21 to 28 (see also 6 ) or whose lower end portions are attached. It should be expressly understood that the present invention is not limited to an octagonal embodiment, but that, for example, square or hexagonal packages as well as those with an odd number of edges can be made using the teachings of the present invention.

In 6 is a floor in plan view 16 with attached side wall parts 21 to 28 shown. In an idealized manner, it is indicated by a circle how the side wall parts designed according to the invention bulge out or round out in the lower region to slightly above the retaining tabs, thereby avoiding material destruction. A similar representation of this fact arises from the perspective front view of 8b) with the below in the (enlarged) plan view of 8c) indicated bulge or rounding of according to 1 with a recess 41 provided lower end portion 31 a side wall part 21 with simultaneous deformation of the retaining tab 11h at the lower end portion 31 is attached, the bottom according to the (enlarged) side sectional view of 8a) , The arrows indicate the assignment of the designated with the ends of the respective arrows areas of the 8a) - 8c) , The cutting plane in 8b) is in between by the two right ends of the two arrows 8a) and 8b) Are defined.

In contrast, in the corresponding 7a) - 7c) a conventional packaging shown, which thus has no weakening sections in the form of, for example, recesses or recesses. In particular, the (enlarged) 7a) shows how can bulge in this conventional packaging, the lower end portion of a side wall portion only with increasing distance from the ground or round and thus much higher Material stresses on the (originally vertical) edges and retaining tabs subject. In this case, the arrows again denote the assignment of the regions of the arrows denoted by the ends of the respective arrows 7a) - 7c) ,

Unlike the above embodiments, the package according to the invention can also be designed in foldable design. For this purpose, the bottom may be designed in several parts, in order to allow a folding and folding, as in 9 is shown by way of example. Several advantageous examples of such a floor, the case of an octagonal packaging (see. 9b ) in corresponding floor parts 11 to 14 is divided into the document EP 1 225 130 A1 shown and described in detail. In 10 is another example of floor parts for octagonal packaging shown, in which not all sidewall parts are usually firmly connected to a retaining tab of the soil. The in the 9a) - 9f) indicated, extending from the respective triangular end piece to the corresponding opposite triangular end piece, partially having an offset lines denote the respective fold lines of the respective bottom parts. Also in 10 drawn, an offset line indicates the fold line of the two floor parts.

For the sake of simplicity and clarity of presentation of the individual embodiments or variants has been assumed above, without limiting the generality and the actual embodiments of the packaging, that in each individual embodiment / variant each side wall parts of a n-sided packaging equal (each with the same length Side edges) or similar (if the length deviates at least one side edge) and thus all side wall parts have a same or similar designed weakening section. It is understood that any desired combinations of the aforementioned embodiments or individual details of these embodiments can be made for the design of the individual side wall parts of a package.

In the above description it was assumed that the packaging is made of corrugated cardboard. However, it can also be made of other materials, such as paper or plastic.

It should be understood that the features of the invention described with reference to particular embodiments, such as the nature and configuration of the floor, the sidewall portions, weakening portions and retaining tabs, may be present in other embodiments as well, unless stated otherwise banned by itself for technical reasons. Moreover, such features of individual embodiments described in combination need not necessarily always be realized in a particular embodiment.
