Description

Die vorliegende Erfindung betrifft einen Karton mit einem faltbaren Isolierbehälter in seinem Kartoninnenraum, insbesondere einen Faltkarton.The present invention relates to a carton with a foldable insulating container in its carton interior, in particular a folding carton.

Die Erfindung geht von Kartons, insbesondere Faltkartons aus, auf deren Kartoninnenseite Isoliermaterial fixiert ist. Das Isoliermaterial kann aufkaschiert, aufgeklebt oder in sonstiger Weise fixiert werden. Da diese Kartons zum Falten Falze und/oder Lücken aufweisen, ist die Isolierung teilweise unterbrochen. Durch diese Unterbrechungen kann Wärme in das Kartoninnere gelangen und so die Isolierwirkung des Kartons beeinträchtigen.The invention is based on cardboard boxes, in particular folding boxes, on the inside of which insulating material is fixed. The insulating material can be laminated, glued on or fixed in any other way. Since these cardboard boxes have folds and / or gaps for folding, the insulation is partially interrupted. These interruptions can cause heat to penetrate the inside of the box and thus impair the insulating effect of the box.

Aus der WO 2011/017793 A1 ist ein Karton mit verbesserter Isolierung bekannt. Der Karton besteht aus einem Außenkarton einerseits und einer in den Innenraum dieses Kartons hineingestellten Auskleidung aus Isoliermaterial andererseits. Die Auskleidung ist ihrerseits wiederum nach Art einer Faltkiste ausgestaltet mit beidseitig auf Karton- oder Zellstoffmaterial aufkaschierten Schichten aus Isoliermaterial.From the WO 2011/017793 A1 a cardboard box with improved insulation is known. The carton consists of an outer carton on the one hand and a lining made of insulating material placed in the interior of this carton on the other hand. The lining is in turn designed in the manner of a folding box with layers of insulating material laminated onto cardboard or cellulose material on both sides.

Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, einen verbesserten Karton mit Isolierung zu realisieren.Based on this, the invention is based on the object of realizing an improved cardboard box with insulation.

Diese Aufgabe ist durch die Merkmalskombination des Anspruchs 1 gelöst. Die rückbezogenen Ansprüche beinhalten teilweise vorteilhafte und teilweise für sich selbst erfinderische Weiterbildungen dieser Erfindung.This object is achieved by the combination of features of claim 1. The claims referring back contain partly advantageous and partly inventive developments of this invention.

Die Erfindung beruht auf der Grundüberlegung, im Kartoninnenraum eines üblichen Kartons einen weiteren faltbaren und einstückigen Isolierbehälter anzuordnen. Dieser Isolierbehälter ist einteilig bzw. einstückig und kann so gefaltet werden, dass der in seine Endstellung gefaltete Isolierbehälter an den Kartoninnenraum angepasst ist. Wichtig ist dabei, dass der Isolierbehälter seinerseits in sich abgeschlossen ist, um eine Bildung von Wärmebrücken gegenüber den Innenwandungen des Kartons zu verhindern.The invention is based on the basic idea of arranging another foldable and one-piece insulating container in the interior of a conventional cardboard box. This insulating container is in one piece or in one piece and can be folded in such a way that the insulating container folded into its end position is adapted to the interior of the box. It is important that the insulated container is in itself is completed in order to prevent the formation of thermal bridges against the inner walls of the cardboard.

Dieser Isolierbehälter besteht aus Isoliermaterial, beispielsweise einer isolierenden Folie, Isoliermatten oder dergleichen. Beim aufgestellten Karton bzw. aufgefalteten Faltkarton liegen die Außenwandungen des Isolierbehälters an den Innenwandungen des Kartons an. Die Wandungen, also die Seitenwände, der
Boden und der Deckel des Isolierbehälters sind in ihrer Größe so an die Wandungen des Faltkartons angepasst, dass der Isolierbehälter in den Kartoninnenraum des Faltkartons hinein passt. Vorteilhaft ist es, wenn der Isolierbehälter geringfügig größer ist als der Kartoninnenraum. Der Isolierbehälter kann dann immer noch problemlos in den Kartoninnenraum eingebracht werden. Allerdings wellen sich die Außenflächen der Wandungen des Isolierbehälters geringfügig, so dass Hohlräume oder Freiräume im Kartoninnenraum des Kartons vom Material des Isolierbehälters ausgefüllt bzw. ausgepolstert werden. Dieses geringfügige Übermaß des Isolierbehälters gegenüber dem Kartoninnenraum ist beispielsweise dadurch realisierbar, dass die Flächen der Wandungen des Isolierbehälters und die Flächen der jeweils benachbarten Wandungen des Kartons gleich groß sind und die Wandstärke der Wandungen des Isolierbehälters so dick gewählt sind, dass sie gleichsam in die vorerwähnten Hohlräume oder Freiräume hinein quillen.This insulating container consists of insulating material, for example an insulating film, insulating mats or the like. When the cardboard box is set up or when the cardboard box is unfolded, the outer walls of the insulating container rest against the inner walls of the cardboard box. The walls, so the side walls, the
The size of the bottom and the lid of the insulating container are adapted to the walls of the folding box so that the insulating container fits into the interior of the folding box. It is advantageous if the insulating container is slightly larger than the interior of the box. The insulated container can then still be inserted into the interior of the box without any problems. However, the outer surfaces of the walls of the insulating container are slightly corrugated, so that cavities or free spaces in the interior of the cardboard box are filled or padded with the material of the insulating container. This slight oversize of the insulated container compared to the interior of the box can be achieved, for example, in that the surfaces of the walls of the insulated container and the areas of the respective adjacent walls of the box are of the same size and the wall thickness of the walls of the insulated container is chosen to be so thick that they, as it were, fit into the aforementioned Hollow spaces or free spaces swell into it.

Erfindungsgemäß sind die Außenwandungen des Isolierbehälters an den Innenwandungen des Kartons fixiert, beispielsweise mit Hilfe einer Klebefolie angeklebt. Auf diese Weise ist es beispielsweise möglich, den faltbaren Isolierbehälter bereits am aufgefalteten Zuschnitt eines Faltkartons zu adaptieren und den aus Faltkarton und faltbarem Isolierbehälter bestehenden Faltkarton in einem einzigen Faltvorgang aufzustellen. Dies kann der Kunde somit selbst bewerkstelligen. Auch ist es vorteilhaft, den Faltkarton mit dem daran adaptierten Isolierbehälter vor oder nach dem Transport teilweise oder ganz aufzufalten, um so den Faltkarton flach lagern zu können oder ihn flachbauend und damit platzsparend transportieren zu können.According to the invention, the outer walls of the insulating container are fixed to the inner walls of the cardboard box, for example glued with the aid of an adhesive film. In this way, it is possible, for example, to adapt the foldable insulating container to the unfolded blank of a folding carton and to set up the folding carton consisting of the folding carton and the foldable insulating container in a single folding process. The customer can do this himself. It is also advantageous to partially or completely unfold the folding box with the insulating container adapted to it before or after transport in order to be able to store the folding box flat or to be able to transport it flat and thus space-saving.

In weiterer vorteilhafter Ausgestaltung hat eine Wandung des Isolierbehälters eine größere Fläche als die ihr zugeordnete Wandung des Kartons. Auf diese Weise wellen sich wiederum die Außenflächen der Wandungen des Isolierbehälters nach außen und können so in Hohlräume oder Freiräume des Kartoninnenraums des Faltkartons eindringen und diese ausfüllen.In a further advantageous embodiment, one wall of the insulating container has a larger area than the wall of the cardboard that is assigned to it. In this way In turn, the outer surfaces of the walls of the insulating container corrugate outwards and can thus penetrate into cavities or free spaces in the interior of the folding box and fill them up.

Sofern in diesem Text der Begriff "Wandung" verwendet wird, kann es sich alternativ um die Vorderwand, Seitenwand, Rückwand, den Boden oder den Deckel des Kartons und/oder des Isolierbehälters handeln. Der Begriff "Wandung" soll gleichsam als Oberbegriff für ein Wandelement stehen unabhängig, ob dies den Boden, den Deckel oder eine wie auch immer geartete Wand des Faltkartons bzw. des Isolierbehälters betrifft.If the term “wall” is used in this text, it can alternatively be the front wall, side wall, rear wall, bottom or lid of the cardboard box and / or the insulating container. The term "wall" should be used as a generic term for a wall element, regardless of whether this relates to the base, the lid or any type of wall of the folding box or the insulating container.

Die vorliegende Erfindung eignet sich besonders gut für Faltkartons. Allerdings ist die Wirkung des Isolierbehälters auch mit andersartig aufgebauten Kartons realisierbar. Beispielsweise kann der Karton auch zusammengesteckt sein. Die Erfindung eignet sich also für sämtliche Arten von Kartons.The present invention is particularly suitable for folding cartons. However, the effect of the insulated container can also be achieved with cardboard boxes with a different structure. For example, the box can also be plugged together. The invention is therefore suitable for all types of cardboard.

In weiterer vorteilhafter Ausgestaltung ist die Fläche des Isolierbehälterbodens größer als diejenige des Kartonbodens. Dies bewirkt die bereits angesprochene Wellung des Isoliermaterials des Isolierbehälters. Die Randbereiche zwischen den Seitenwänden des Isolierbehälters bilden auf diese Weise polsterungsartige Wülste bzw. Aufpolsterungen aus. Nach Art von Dichtringen oder Dichtgummis füllen diese wulstartigen Randbereiche des Isolierbehälters die von den Seitenwänden eines Faltkartons gebildeten Eckbereiche aus. Da gerade in den Eckbereichen Rillungen oder Schwächungen zum Falten der Seitenwände eines Faltkartons ausgebildet sind, verbessern diese Wülste die Dichtwirkung des Isolierbehälters insbesondere in entsprechenden Randbereichen eines Faltkartons.In a further advantageous embodiment, the area of the insulating container bottom is larger than that of the cardboard bottom. This causes the already mentioned corrugation of the insulating material of the insulating container. In this way, the edge areas between the side walls of the insulating container form padding-like bulges or upholstery. In the manner of sealing rings or rubber seals, these bead-like edge areas of the insulating container fill the corner areas formed by the side walls of a folding box. Since grooves or weaknesses for folding the side walls of a folding box are formed in the corner areas, these beads improve the sealing effect of the insulating container, especially in the corresponding edge areas of a folding box.

Zur weiteren Verbesserung der Dichtwirkung ist vorgeschlagen, die schwenkbaren Laschen an den Oberkanten bzw. den Unterkanten der Seitenwände des Isolierbehälters mit dem jeweils benachbarten Isolierbehälterdeckel oder Isolierbehälterboden zu verbinden. Wird der Isolierbehälter in seine Transportstellung aufgefaltet, bilden sich zwischen den Laschen und dem Isolierbehälterdeckel bzw. Isolierbehälterboden Überlappungen und doppeln so das Dichtmaterial in diesem Bereich gleichsam auf. Auch diese Maßnahme führt zu einer Verbesserung der Isolierwirkung in den neuralgischen Kantenbereichen bzw. Eckbereichen.To further improve the sealing effect, it is proposed to connect the pivotable tabs on the upper edges or the lower edges of the side walls of the insulating container to the respectively adjacent insulating container lid or insulating container base. If the insulating container is unfolded into its transport position, overlaps are formed between the tabs and the insulating container lid or insulating container bottom, thus doubling the sealing material in this area as it were on. This measure also leads to an improvement in the insulating effect in the neuralgic edge areas or corner areas.

Auch wirken diese Überlappungen einem Absinken der Isolierleistung des Isolierbehälters entgegen, wenn der Karton in Kantenbereichen beispielsweise beschädigt ist.These overlaps also counteract a decrease in the insulating performance of the insulating container if the box is damaged in edge areas, for example.

Anhand des nachfolgenden Ausführungsbeispiels ist die Erfindung mit weiteren Einzelheiten beschreiben. Es zeigen:

With the aid of these adhesive points 23, the in Fig. 2 The blank of the insulating container 15 shown is fixed on the box 1 before it is unfolded.

Mit Hilfe von Maßpfeilen sind jeweils die Eigenlänge 24 und die Eigenbreite 25 der Kartonvorderwand 2, der Kartonseitenwände 3, der Kartonrückwand 4, des Kartonbodens 5 und des Kartondeckels 6 des Kartons 1 einerseits sowie der Behältervorderwand 16, der Behälterseitenwände 17, der Behälterrückwand 18, des Behälterbodens 19 und des Behälterdeckels 20 des Isolierbehälters 15 andererseits angedeutet. Beim Ausführungsbeispiel sind die Eigenlänge 24 und die Eigenbreite 25 der Kartonvorderwand 2, der Kartonseitenwände 3, der Kartonrückwand 4 und des Kartondeckels 6 jeweils größer oder gleich der Eigenlänge 24 bzw. der Eigenbreite 25 der entsprechenden Behältervorderwand 16, Behälterseitenwände 17, Behälterrückwand 18 und Behälterdeckel 20. Im Falle des Behälterbodens 19 ist dessen Eigenbreite 25 größer als die Eigenbreite 25 des entsprechenden Kartonbodens 5. Auf diese Weise weist der Behälterboden 19 eine größere Fläche als der Kartonboden 5 auf.With the help of dimension arrows, the intrinsic length 24 and intrinsic width 25 of the carton front wall 2, the carton side walls 3, the carton back wall 4, the carton bottom 5 and the carton lid 6 of the carton 1 on the one hand and the container front wall 16, the container side walls 17, the container rear wall 18, the Container bottom 19 and the container lid 20 of the insulating container 15 on the other hand indicated. In the exemplary embodiment, the intrinsic length 24 and intrinsic width 25 of the carton front wall 2, the carton side walls 3, the carton back wall 4 and the carton lid 6 are each greater than or equal to the intrinsic length 24 and intrinsic width 25 of the corresponding container front wall 16, container side walls 17, container rear wall 18 and container lid 20 In the case of the container base 19, its inherent width 25 is greater than the inherent width 25 of the corresponding cardboard base 5. In this way, the container base 19 has a larger area than the cardboard base 5.

Der Karton 1 weist zwischen seinen schwenkbaren Elementen jeweils Falzkanten 26 auf. Nach dem Aufstellen des Faltkartons 1 und des mit dem Faltkarton 1 über die Klebestellen 23 verbundenen Isolierbehälters 15 bilden sich in Folge des Übermaßes des Isolierbehälters 15 gegenüber dem Innenraum des Faltkartons 1 Wülste oder dergleichen am Isolierbehälter 15 aus. Diese Wülste ragen in die Falzkanten 26 hinein und füllen die Falzkanten 26 am aufgestellten Karton 1 isolierend aus. Dasselbe gilt für die bereits erwähnten Überlappungen 22, die in Freiräume 27 am Karton 1 hineinragen.The carton 1 has folded edges 26 between its pivotable elements. After the folding box 1 and the insulating container 15 connected to the folding cardboard 1 via the glues 23 have been erected, bulges or the like are formed on the insulating container 15 as a result of the oversize of the insulating container 15 relative to the interior of the folding cardboard box 1. These beads protrude into the folded edges 26 and fill the folded edges 26 on the cardboard 1 that has been set up in an insulating manner. The same applies to the already mentioned overlaps 22, which protrude into free spaces 27 on the box 1.
