Description

Die vorliegende Erfindung betrifft eine Verpackungseinheit gemäß dem Oberbegriff des Patentanspruches 1 und ein Verfahren zur Herstellung einer Verpackungseinheit gemäß dem Oberbegriff des Patentanspruches 10.The present invention relates to a packaging unit according to the preamble of claim 1 and a method for producing a packaging unit according to the preamble of claim 10.

Verpackungseinheiten aus einzelnen zu einer Produktformation zusammengefassten Produkten, insbesondere Dosen oder dgl. Behälter, die mittels einer schrumpffähigen Folie gegeneinander fixiert sind, sind hinlänglich bekannt.Packaging units made of individual products grouped into a product formation, in particular cans or the like. Containers which are fixed relative to one another by means of a shrinkable film are well known.

Zur Herstellung derartiger Verpackungseinheiten, wie beispielsweise in der DE 10 2008 052 633 A1 beschrieben, wird die Schrumpffolie um die Produktformation unter Bildung zweiter gegenüberliegender seitlicher, vorzugsweise stirnseitiger Öffnungen geschlungen und anschließend aufgeschrumpft. Im Bereich dieser seitlichen Öffnungen ist die Schrumpffolie mit einer geschlossenen Oberfläche in Gestalt eines Verschlusses mit sich überlappenden Faltbereichen ausgebildet. Hierdurch weisen derartige Verpackungseinheiten bzw. die aufgeschrumpfte Folie zwei gegenüberliegende stirnseitige Schrumpfaugen auf, die sich an den gegenüberliegenden Seitenflächen ausbilden. Die aufgeschrumpfte Folie bildet in einer Ausführungsvariante eine geschlossene Fläche aus. Alternativ kann die schrumpfende bzw. aufgeschrumpfte Folie im Bereich dieser Schrumpfaugen eine Öffnung aufweisen. Insbesondere ein Abstellen der Verpackungseinheit mit der Stirnseite auf einem mit Steinen oder anderweitigen spitzen Partikeln übersäten Bodenbereich kann dazu führen, dass die in der Verpackungseinheit aufgenommenen Produkte, insbesondere Dosen beschädigt werden und das darin aufgenommene Füllgut, beispielsweise Bier austritt.For producing such packaging units, such as in the DE 10 2008 052 633 A1 described, the shrink film is wrapped around the product formation to form second opposite lateral, preferably frontal openings and then shrunk. In the area of these lateral openings, the shrink film is formed with a closed surface in the form of a closure with overlapping fold areas. As a result, such packaging units or the shrunk-on film have two opposite end-side shrinkage eyes, which form on the opposite side surfaces. The shrunk-on film forms in a variant of a closed surface. Alternatively, the shrinking or shrunk-on film can have an opening in the region of these shrinkage eyes. In particular, placing the packaging unit with the end face on a floor area covered with stones or other pointed particles can result in the products accommodated in the packaging unit, in particular cans, being damaged and the contents, for example beer, absorbed therein being discharged.

Auch sind bereits derartige folienverpackte Verpackungseinheiten bekannt, bei denen Dosen auf einen im Querschnitt U-förmigen Trägerelement aus Pappe aufgenommen sind, wobei die Produkte bzw. Dosen sich auf einem rechteckförmigen Aufnahmeabschnitt des Tragelementes befinden und an dessen Randseiten sich zwei angeflanschte Wandabschnitte anschließen, welche jedoch eine geringe Breite besitzen. Die Wandabschnitte des Tragelementes erstrecken sich hinsichtlich ihrer Breite maximal bis zu einem Drittel der Höhe der Produkte bzw. der Dosenhöhe.Also such film-wrapped packaging units are already known in which cans are received on a cross-sectionally U-shaped support element made of cardboard, the products or cans are on a rectangular receiving portion of the support element and adjoin the edge sides of two flanged wall sections, which, however have a small width. The wall sections of the support element extend with respect to their width up to a maximum of one third of the height of the products or the can height.

Somit besteht auch bei derartigen bekannten, auch "U-Boards" genannten Tragelement weiterhin der Nachteil, dass bei Abstellen der folienverpackten Verpackungseinheit auf der Stirnseite eine Beschädigung der Dosen entstehen kann.Thus, there is also the disadvantage in such known, also called "U-boards" supporting element that when the film-wrapped packaging unit is placed on the front side damage to the cans can occur.

Es ist daher Aufgabe der vorliegenden Erfindung, eine Verpackungseinheit und ein zugehöriges Verfahren zur Herstellung einer derartigen Verpackungseinheit anzugeben, die die eingangs beschriebenen Nachteile des Standes der Technik beseitigt, insbesondere einen verbesserten Schutz der in der Verpackungseinheit aufgenommenen Produkte, insbesondere Dosen durch äußere mechanische Einflüsse, beispielsweise beim Abstellen auf mit spitzen Partikeln verunreinigtem Boden, zu ermöglichen.It is therefore an object of the present invention to provide a packaging unit and an associated method for producing such a packaging unit, which eliminates the disadvantages of the prior art described above, in particular improved protection of the products received in the packaging unit, in particular cans due to external mechanical influences, for example, when parking on soil contaminated with spiky particles.

Die Aufgabe wird ausgehend von dem Oberbegriff des Patentanspruches 1 durch dessen kennzeichnende Merkmale gelöst. Weiterhin wird die Aufgabe durch ein Verfahren zur Herstellung einer Verpackungseinheit gemäß dem Oberbegriff des Patentanspruches 10 durch dessen kennzeichnende Merkmale gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.The object is achieved on the basis of the preamble of claim 1 by its characterizing features. Furthermore, the object is achieved by a method for producing a packaging unit according to the preamble of claim 10 by its characterizing features. Advantageous developments of the invention are the subject of the dependent claims.

Der wesentliche Aspekt der erfindungsgemäßen Verpackungseinheit ist darin zu sehen, dass zur vollständigen oder nahezu vollständigen Abdeckung zumindest einer der Stirnseiten zumindest ein Abdeckelement vorgesehen ist, welches vor dem Aufschrumpfen der Folie im Bereich zumindest einer der Stirnseiten an der Produktformation fixiert ist. Besonders vorteilhaft kann durch die erfindungsgemäße Abdeckung der Stirnseiten der Produktformation bzw. Verpackungseinheit durch das Abdeckelement eine Beschädigung der Produkte, insbesondere Dosen der Verpackungseinheit durch äußere Einflüsse effektiv vermieden werden. Vorteilhaft ist hierzu das zumindest eine Abdeckelement aus Pappe, Wellpappe oder einem ähnlichen Material einstückig hergestellt.The essential aspect of the packaging unit according to the invention is to be seen in that for complete or almost complete coverage of at least one of the end sides at least one cover is provided, which is fixed before shrinking the film in the region of at least one of the end faces on the product formation. Particularly advantageously, damage to the products, in particular cans of the packaging unit due to external influences, can be effectively prevented by the covering according to the invention of the end faces of the product formation or packaging unit by the covering element. For this purpose, the at least one cover element made of cardboard, corrugated cardboard or a similar material is advantageously produced in one piece.

Weiterhin vorteilhaft ist das zumindest eine Abdeckelement flach ausgebildet und weist eine Breite auf, die größer als die Hälfte der Produkthöhe, jedoch kleiner als Produkthöhe ist. Ferner weist das zumindest eine flache Abdeckelement eine Länge auf, die kleiner als die Breite der Verpackungseinheit ist. In dieser Ausführungsvariante ist das zumindest eine Abdeckelement flach und rechteckförmig, oval oder rund ausgebildet.Further advantageously, the at least one cover is flat and has a width which is greater than half the product height, but smaller than product height. Furthermore, the at least one flat cover element has a length that is smaller than the width of the packaging unit. In this embodiment the at least one cover is flat and rectangular, oval or round.

In einer alternativen Ausführungsvariante ist das zumindest eine Abdeckelement U-förmig ausgebildet. Dadurch wird zusätzlich ein effektiver Schutz der Eckebereich der Verpackungseinheit erreicht.In an alternative embodiment variant, the at least one cover element is U-shaped. As a result, an effective protection of the corner region of the packaging unit is additionally achieved.

Gemäß einer weiteren Ausführungsvariante sind ein erstes und ein zweites Abdeckelement vorgesehen, wobei das erste Abdeckelement zur vollständigen Abdeckung der ersten Öffnung und das zweite Abdeckelement zur vollständigen Abdeckung der zweiten Öffnung ausgebildet ist.According to a further embodiment variant, a first and a second cover element are provided, wherein the first cover element is designed to completely cover the first opening and the second cover element to completely cover the second opening.

Vorteilhaft ist das zumindest eine Abdeckelement mit der Produktformation bzw. einzelnen Produkten verklebt.Advantageously, the at least one covering element is glued to the product formation or individual products.

Ebenfalls ist Gegenstand der Erfindung ein Verfahren zur Herstellung zumindest einer Verpackungseinheit bestehend aus einzelnen zu einer Produktformation zusammengefassten Produkten und einer aufgeschrumpften Folie, bei dem die Produkte mittels der aufgeschrumpften Folie gegeneinander fixiert werden, wobei die Verpackungseinheit zumindest zwei gegenüberliegende Stirnseiten aufweist. Vorteilhaft wird vor dem Aufschrumpfen der Folie zumindest ein Abdeckelement im Bereich zumindest einer Stirnseite an der Produktformation fixiert wird.The invention likewise provides a process for producing at least one packaging unit consisting of individual products combined to form a product formation and a shrunk-on film, in which the products are fixed against one another by means of the shrunk-on film, the packaging unit having at least two opposite end faces. Advantageously, at least one cover element is fixed in the region of at least one end face on the product formation before shrinking the film.

Vorzugsweise werden vor dem Aufschrumpfen der Folie die Produkte und/oder das zumindest eine Abdeckelement mit einem Klebstoffauftrag versehen, wobei dieser beispielsweise durch Sprühen hergestellt werden kann.Preferably, before shrinking the film, the products and / or the at least one covering provided with an adhesive, which can be prepared for example by spraying.

  • Fig. 6 a schematic cross section through an inventively designed packaging unit with two flat cover according to FIG. 3 and
  • Fig. 7 a perspective top view of an inventively designed packaging unit with an alternative embodiment of a flat cover.

Figur 1 zeigt eine Verpackungseinheit 1 gemäß dem Stand der Technik bestehend aus einzelnen zu einer Produktformation zusammengefassten Produkten 2, insbesondere Dosen. Die Produkte 2 weisen eine Produkthöhe H auf, welche die Erstreckung entlang Ihrer Produktlängsachse widergibt. Die Verpackungseinheit 1 ist aufgrund der Anordnung der Produkte 2 in einer Produktformation vorzugsweise quaderförmig ausgebildet und weist zwei gegenüberliegende Stirnseiten 1a, 1b und zwei gegenüberliegende Längsseiten 1c, 1d. Schließlich weist die Verpackungseinheit 1 noch eine Oberseite 1e und eine Unterseite 1f auf. FIG. 1 shows a packaging unit 1 according to the prior art consisting of individual combined into a product formation products 2, in particular cans. The products 2 have a product height H, which reflects the extent along their product longitudinal axis. The packaging unit 1 is preferably cuboid in shape due to the arrangement of the products 2 in a product formation and has two opposite end faces 1a, 1b and two opposite longitudinal sides 1c, 1d. Finally, the packaging unit 1 still has an upper side 1e and a lower side 1f.

Die Produkte 2 sind beispielhaft auf einem flachen Tragelement 3 aufgenommen, und zwar stehender Weise, d.h. die Produktlängsachse verläuft senkrecht zur Oberseite des flachen Tragelementes 3, welches vorzugsweise aus Pappe, Wellpappe oder einem vergleichbaren Material hergestellt ist. Beispielsweise kann das flache Tragelement 3 auch aus Kunststoff hergestellt sein oder auch vollständig entfallen.The products 2 are exemplarily taken on a flat support member 3, and standing manner, ie the product longitudinal axis is perpendicular to the top of the flat support member 3, which is preferably made of cardboard, corrugated cardboard or a comparable material. For example, the flat support member 3 may also be made of plastic or completely eliminated.

Das flache Tragelement 3 weist zumindest einen rechteckförmigen Aufnahmeabschnitt 3.1 auf, auf dem die Produkte 2, insbesondere Dosen stehend angeordnet sind, und zwar vorzugsweise unmittelbar nebeneinander und matrixartig angeordnet, d.h. in mehreren Reihen und Spalten nebeneinander. Der rechteckförmige Aufnahmeabschnitt 3.1 des flachen Tragelementes 3 bildet hierbei die Unterseite 1f der Verpackungseinheit 1. Im vorliegenden Ausführungsbeispiel umfasst die Verpackungseinheit 1 vier Spalten mit jeweils sechs Dosen, d.h. in Summe 24 Dosen. Es versteht sich, dass die Erfindung keinesfalls auf eine derartige Anzahl an Produkten 2 bzw. Dosen beschränkt ist, sondern auch eine unterschiedliche Anzahl an Produkten 2 pro Verpackungseinheit 1 umfassen kann, ohne das hierdurch der Erfindungsgedanke verlassen wird.The flat support element 3 has at least one rectangular receiving section 3.1, on which the products 2, in particular cans are arranged vertically, preferably directly next to each other and arranged in a matrix, i. in several rows and columns next to each other. The rectangular receiving portion 3.1 of the flat support element 3 here forms the bottom 1f of the packaging unit 1. In the present embodiment, the packaging unit 1 comprises four columns each having six cans, i. in total 24 doses. It is understood that the invention is by no means limited to such a number of products 2 or cans, but may also include a different number of products 2 per packaging unit 1, without thereby departing from the inventive idea.

Die Verpackungseinheit 1 weist eine schrumpffähige Folie 4 auf, mittels der die auf dem rechteckförmigen Aufnahmeabschnitt 3.1 befindlichen Produkte 2 gegeneinander und am flachen Tragelement 3 fixiert sind. Zur Herstellung derartiger Verpackungseinheiten 1 wird die schrumpffähige Folie 4 um die Produktformation geschlungen, und zwar derart, dass diese im Bereich der Stirnseiten 1a, 1b der Verpackungseinheit 1 eine Öffnung bildet. Anschließend wird die schrumpffähige Folie 4 in einer zugehörigen Schrumpftunnelanlage aufgeschrumpft, wodurch die Stirnseiten 1a, 1b entweder vollflächig mit der aufgeschrumpften Folie 4 bedeckt sind oder diese nur teilweise bedeckt sind, d.h. die schrumpffähige Folie bzw. Schrumpffolie 4 zwei gegenüberliegende stirnseitige Öffnungen 4a, 4b ausbildet, die sich an den gegenüberliegenden Stirnseiten 1a, 1b der Verpackungseinheit 1 befinden. Im Bereich dieser Öffnungen 4a, 4b bzw. Schrumpfaugen weist die schrumpfende bzw. aufgeschrumpfte Folie 4 damit keine geschlossene Fläche auf. Insbesondere in diesem Bereich ist ein direkter Kontakt der in der Verpackungseinheit 1 aufgenommenen Produkte 2, insbesondere von Dosen mit der äußeren Umgebung möglich.The packaging unit 1 has a shrinkable film 4, by means of which the products 2 located on the rectangular receiving section 3.1 are fixed relative to one another and to the flat supporting element 3. For producing such packaging units 1, the shrinkable film 4 is wrapped around the product formation in such a way that it forms an opening in the region of the end faces 1a, 1b of the packaging unit 1. Subsequently, the shrinkable film 4 is shrunk in an associated shrink tunnel, whereby the end faces 1a, 1b are either completely covered with the shrunk-on film 4 or they are only partially covered, i. the shrinkable film or shrink film 4 forms two opposite end-side openings 4a, 4b, which are located on the opposite end faces 1a, 1b of the packaging unit 1. In the region of these openings 4a, 4b or shrinkage eyes, the shrinking or shrunk-on film 4 thus has no closed surface. In particular in this area, direct contact of the products 2 accommodated in the packaging unit 1, in particular of cans with the external environment, is possible.

Beim Abstellen der Verpackungseinheit 1 auf deren Stirnseiten 1a, 1b kann es bei einem mit Steinen oder anderweitigen spitzen Partikeln 5 übersäten Bodenbereich 6 dazu kommen, dass die in der Verpackungseinheit 1 aufgenommenen Produkte 2, insbesondere Dosen beschädigt werden und das darin aufgenommene Füllgut, beispielsweise Bier austritt.When placing the packaging unit 1 on their end faces 1a, 1b, it may happen that the recorded in the packaging unit 1 products 2, in particular cans are damaged and received therein contents, such as beer in a stony or otherwise pointed particles 5 littered bottom area exit.
