Description

Die Erfindung betrifft eine Kartonverpackung mit einem äußeren Faltkarton und einem inneren Faltkarton, der ein Folieninnenbehältnis umgibt. So eine Kartonverpackung ist aus WO 02/083510 bekannt.
Vorzugsweise umgeben der äußere und der innere Faltkarton das Folieninnenbehältnis im Wesentlichen vollständig. Das Folieninnenbehältnis besteht üblicherweise aus einem mit einem Entnahmeverschluss versehenen flexiblen Folieninnenbeutel enthält.The invention relates to a cardboard packaging with an outer folding carton and an inner folding carton, which surrounds a film inner container. Such a cardboard packaging is out WO 02/083510 known.
Preferably, the outer and inner folding cartons surround the film inner container substantially completely. The film inner container usually consists of a flexible inner film bag provided with a removal closure.

Derartige Flüssigkeitsverpackungen, die zur Lagerung, zum Transport und zur Entnahme von Flüssigkeiten dienen, sind in unterschiedlichen Ausführungsformen bekannt. Die in einem Faltkarton aufgenommenen flexiblen Folieninnenbeutel haben gegenüber starren Flüssigkeitsverpackungen den Vorteil, dass die aufgenommene Flüssigkeit durch den bei der Entnahme kollabierenden Folieninnenbeutel nicht mit dem Luftsauerstoff in Verbindung kommt und daher länger haltbar bleibt.Such liquid packaging used for storage, transport and removal of liquids are known in various embodiments. The flexible inner film bags accommodated in a folding carton have the advantage over rigid liquid packaging that the liquid taken in does not come into contact with the atmospheric oxygen due to the inner film bag collapsing upon removal and therefore remains longer lasting.

In DE 11 20 355 wird eine Faltschachtel mit einem darin angeordneten Kunststoffbeutel beschrieben. Um einen Entnahmeverschluss an einer vorgegebenen Position innerhalb der Faltschachtel festlegen zu können befindet sich ein Halter innerhalb der Faltschachtel, der eine unterhalb des Deckels der Faltschachtel angeordnete Platte mit einer Öffnung zur Aufnahme des Entnahmeverschlusses aufweist. Der Halter kann mittels Befestigungsmittel mit der Faltschachtel verbunden sein, um ein verrutschen des Halters mit dem daran festgelegten Entnahmeverschlusses zu verhindern. Der im Inneren der Faltschachtel angeordnete Halter erhöht die Stabilität der Faltschachtel nur unwesentlich.In DE 11 20 355 a folding box is described with a plastic bag arranged therein. In order to be able to define a removal closure at a predetermined position within the folding box, a holder is located inside the folding box, which has a plate arranged below the lid of the folding box with an opening for receiving the removal closure. The holder may be connected by means of fastening means with the carton to prevent slipping of the holder with the discharge closure fixed thereto. The arranged inside the carton holder increases the stability of the carton only insignificantly.

In DE 30 16 466 A1 wird eine ähnliche Faltschachtel beschrieben, die ebenfalls eine unter dem Deckel der Faltschachtel angeordnete Platte zur Aufnahme des Entnahmeverschlusses aufweist. Diese Platte ist jedoch schräg angeordnet, um beim Befüllen des in der Faltschachtel angeordneten Schlauchs durch den Entnahmeverschluss unerwünschte Lufteinschlüsse in dem Schlauch zu vermeiden. Der Entnahmeverschluss ist deshalb an der höchsten Stelle der schräg angeordneten Platte festgelegt. Die Platte ist auf dem Boden der Faltschachtel abgestützt und seitlich an einer Seitenwand der Faltschachtel befestigt. Auch hier wird die Stabilität der Faltschachtel durch die im Inneren angeordnete und abgestützte Platte nur unwesentlich verbessert.In DE 30 16 466 A1 a similar carton is described, which also arranged under the cover of the carton plate for Recording the removal closure has. However, this plate is arranged obliquely to avoid unwanted air pockets in the tube during the filling of the arranged in the carton tube through the removal closure unwanted air pockets. The removal closure is therefore fixed at the highest point of the slanted plate. The plate is supported on the bottom of the carton and secured laterally to a side wall of the carton. Again, the stability of the carton is improved only insignificantly by the arranged and supported inside plate.

Die insbesondere für den Transport wichtige mechanische Festigkeit der Verpackung wird bei derartigen Kartonverpackungen ausschließlich durch den Faltkarton erreicht, der den Folieninnenbeutel aufnimmt. Der Karton muss in den meisten Fällen sehr stabil sein, um die Vorschriften der Gefahrgutverordnung sowohl bei der Anwendung als auch beim Transport zu erfüllen.
Die Forderungen der Gefahrgutverordnung für die Aufnahme und den Transport von gefährlichen Flüssigkeiten können in vielen Fällen nur dadurch erfüllt werden, dass zusätzlich zu dem den Folieninnenbeutel enthaltenden inneren Faltkarton ein zusätzlicher äußerer Faltkarton verwendet wird.The important in particular for the transport mechanical strength of the packaging is achieved in such cardboard packaging exclusively by the folding carton, which receives the film inner bag. The carton must in most cases be very stable in order to comply with the requirements of the dangerous goods regulations both during use and during transport.
The requirements of the Dangerous Goods Ordinance for the absorption and transport of hazardous liquids can in many cases only be met by the fact that an additional outer folding carton is used in addition to the inner inner carton containing the film inner bag.

Aus der Praxis sind die eingangs genannten Kartonverpackungen mit einem äußeren Faltkarton und einem inneren Faltkarton, der den flexiblen Folieninnenbeutel enthält, bekannt. Derartige Kartonverpackungen für Flüssigkeiten der "Karton-im-Karton"-Bauart sind aber in der Produktion nur umständlich zu verarbeiten. Insbesondere können Sie nicht auf einer vollautomatischen Maschine verarbeitet werden. Auch wenn der den Folieninnenbeutel aufnehmende innere Faltkarton auf einer vollautomatischen Maschine vorbereitet und aufgerichtet werden kann, so muss er doch von Hand in den äußeren Faltkarton eingesetzt werden.From practice, the carton packs mentioned above are known with an outer folding carton and an inner folding carton containing the flexible inner foil bag. However, such cardboard packaging for liquids of the "cardboard-in-carton" type are only cumbersome to process in production. In particular, they can not be processed on a fully automatic machine. Even if the inner folding carton accommodating the inner film bag can be prepared and erected on a fully automatic machine, it nevertheless has to be inserted by hand into the outer folding carton.

Aufgabe der Erfindung ist daher, eine Kartonverpackung der eingangs genannten Gattung zu schaffen, die einfach in der Verarbeitung und beim Abfüllen ist und auch auf einer vollautomatischen Maschine abgefüllt werden kann. Zugleich sollen die für Chemikalien vorgegebenen Gefahrgutbedingungen erfüllt sein. Die Verpackung soll beim Transport und bei der Verwendung hohen Sicherheitsanforderungen entsprechen.The object of the invention is therefore to provide a cardboard packaging of the type mentioned, which is easy to process and filling and can also be filled on a fully automatic machine. At the same time, the dangerous goods conditions specified for chemicals should be met. The packaging should meet high safety requirements during transport and use.

Diese Aufgabe wird durch die Kartonverpackung des Anspruchs 1 gelöst.This object is achieved by the cardboard packaging of claim 1.

Durch die stabile Verbindung des inneren Faltkartons mit dem äußeren Faltkarton wird eine wesentliche erhöhte Gesamtfestigkeit der Kartonverpackung erreicht. Die Handhabung der Kartonverpackung wird wesentlich erleichtert, weil der innere Faltkarton mit dem äußeren Faltkarton sicher und lagegenau durch die Klebung verbunden ist. Insbesondere ist die Lage des inneren Faltkartons im äußeren Faltkarton so festgelegt, dass von außen einwirkende Stöße oder ähnliche Beanspruchungen in optimaler Weise vom inneren Faltkarton und insbesondere von dem Folieninnenbeutel ferngehalten werden.Due to the stable connection of the inner folding carton with the outer folding carton a substantial increased overall strength of the cardboard packaging is achieved. The handling of the cardboard packaging is greatly facilitated because the inner folding carton is securely and accurately connected to the outer folding carton through the bond. In particular, the position of the inner folding carton in the outer folding carton is set so that externally applied shocks or similar stresses are optimally kept away from the inner folding carton and in particular from the inner foil bag.

Vorzugsweise bestehen der äußere und der innere Faltkarton aus Wellpappe. Es ist jedoch auch denkbar und für einige Anwendungen vorteilhaft, wenn der äußere und/oder der innere Faltkarton teilweise oder vollständig aus einem Kunststoffmaterial oder aus einem Verbundmaterial bestehen.Preferably, the outer and inner folding cartons are made of corrugated cardboard. However, it is also conceivable and advantageous for some applications when the outer and / or the inner folding carton partially or completely made of a plastic material or of a composite material.

Auch der Befüllungsvorgang wird vereinfacht und erleichtert, weil das das Folieninnenbehältnis aufnehmende Kartongebilde wegen der Klebeverbindung zwischen dem inneren Faltkarton und dem äußeren Faltkarton wie ein einheitlicher Faltkarton gehandhabt werden kann. Dadurch wird auch die Verarbeitung auf einer vollautomatischen Maschine beim Aufrichten, Befüllen und Verschließen der Flüssigkeitsverpackung ermöglicht und erleichtert. Das Folieninnenbehältnis ist vorzugsweise ein flexibler Folieninnenbeutel mit einem Entnahmeverschluss. Es ist jedoch auch denkbar, dass das Folieninnenbehältnis durch eine im Wesentlichen formstabile Folienblase oder durch eine Folienbeschichtung des inneren Faltkartons gebildet wird.Also, the filling process is simplified and facilitated because the film inner container receiving carton can be handled because of the adhesive bond between the inner carton and the outer folding carton as a single folding carton. This also makes the processing on a fully automatic machine when erecting, filling and closing the liquid packaging allows and facilitates. The film inner container is preferably a flexible film inner bag with a removal closure. However, it is also conceivable that the film inner container is formed by a substantially dimensionally stable film bubble or by a film coating of the inner folding carton.

Erfindungsgemäße Ausgestaltungen der Kartonverpackung sind Gegenstand von Unteransprüchen.Inventive embodiments of the cardboard packaging are the subject of dependent claims.

Die Erfindung betrifft auch eine vorgefertigte Kartoneinheit zur Herstellung einer voran gehend beschriebenen Kartonverpackung sowie ein Verfahren zur Herstellung einer solchen Kartonverpackung.The invention also relates to a prefabricated cardboard unit for producing a previously described cardboard packaging and to a method for producing such a cardboard packaging.

Die Erfindung wird anhand des nachfolgend beschriebenen und in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Es zeigt:

  • Fig. 8 a flat blank for making the outer carton,
  • Fig. 9 in a schematic representation, a prefabricated cardboard unit for producing a cardboard packaging and
  • Fig. 10 a sectional view of the cardboard packaging with obliquely arranged cover flaps of an inner folding carton.

Die in den Fig. 1 - 6 dargestellte Kartonverpackung weist einen äußeren Faltkarton 1 und einen inneren Faltkarton 2 auf, der einen mit einem Entnahmeverschluss 3 versehenen, flexiblen Folieninnenbeutel 4 enthält, der zur Aufnahme der zu verpackenden Flüssigkeit bestimmt ist.The in the Fig. 1 - 6 shown cardboard packaging has an outer folding carton 1 and an inner folding carton 2, which contains a provided with a removal closure 3, flexible film inner bag 4, which is intended to receive the liquid to be packaged.

Der hier nicht näher dargestellte Entnahmeverschluss 3 kann ein Hahn sein. Wenn die Kartonverpackung zur Aufnahme von beispielsweise Titrierflüssigkeit dient, kann der in den Entnahmeverschluss integrierte Hahn in einfacher Weise mit einem Titrator über einen (nicht dargestellten) Adapter verbunden werden. Da der Folieninnenbeutel 4 bei der Entnahme der Flüssigkeit kollabiert, besteht keine Gefahr, dass die Flüssigkeit kontaminiert wird. Luftblasen gelangen nicht in den Folieninnenbeutel 4.The extraction closure 3, not shown here, may be a faucet. If the cardboard packaging is used to hold, for example, titration liquid, the tap integrated in the extraction closure can be easily connected to a titrator via an adapter (not shown). Since the film inner bag 4 collapses upon removal of the liquid, there is no danger that the liquid will be contaminated. Air bubbles do not enter the film inner bag 4.

Der äußere Faltkarton 1 weist vier Kartonzargenwände 5, 6, 7 und 8 auf, die an Zargenkanten 9, 10, 11 und 12 zur Bildung einer Kartonzarge faltbar miteinander verbunden sind.The outer folding carton 1 has four Kartonzargenwände 5, 6, 7 and 8, which are connected to Zargenkanten 9, 10, 11 and 12 foldable together to form a cardboard frame.

In entsprechender Weise weist der innere Faltkarton 2 Kartonzargenwände 13, 14, 15 und 16 auf, die an Zargenkanten 17, 18, 19 und 20 zu einer Kartonzarge verbunden sind.Correspondingly, the inner folding carton 2 has cardboard frame walls 13, 14, 15 and 16, which are connected to frame edges 17, 18, 19 and 20 to form a cardboard frame.

Der äußere Faltkarton 1 und der innere Faltkarton 2 sind jeweils aus einer Kartonfalthülse gebildet, die jeweils in einer Kartonzargenwand 8 bzw. 16 eine Klebeverbindung 21 bzw. 22 aufweist (Fig. 2).The outer folding carton 1 and the inner folding carton 2 are each formed from a carton folding sleeve, which in each case in a cardboard frame wall 8 or 16 has an adhesive bond 21 or 22 ( Fig. 2 ).

Der äußere Faltkarton 1 weist jeweils an den Oberkanten 23, 24, 25 und 26 seiner Kartonzargenwände 5, 6, 7 und 8 faltbar angelenkte Deckelklappen 27, 28, 29, und 30 auf.The outer folding carton 1 has in each case at the upper edges 23, 24, 25 and 26 of its cardboard frame walls 5, 6, 7 and 8 hingedly hinged lid flaps 27, 28, 29, and 30.

Der innere Faltkarton 1 und der äußere Faltkarton 2 weist jeweils an den Unterkanten 39 bzw. 40 seiner Kartonzargenwände 13, 14, 15, 16 bzw. 5, 6, 7, 8 faltbar angelenkte Bodenklappen 41 bzw. 42 auf.The inner folding carton 1 and the outer folding carton 2 each have at the lower edges 39 and 40 of its cardboard frame walls 13, 14, 15, 16 and 5, 6, 7, 8 hinged bottom flaps 41 and 42, respectively.

Der innere Faltkarton 2 ist mit seiner einen Kartonzargenwand 14 mit der benachbarten Kartonzargenwand 6 des äußeren Faltkartons 1 mittels streifenförmig aufgetragenem Kleber 43 verklebt. Zusätzlich kann (hier nicht dargestellt) eine Verklebung auch zwischen den jeweils benachbarten Kartonzargenwänden 5 und 13 oder 7 und 15 vorgesehen sein.The inner folding carton 2 is adhesively bonded with its one carton frame wall 14 to the adjacent carton frame wall 6 of the outer folding carton 1 by means of a strip-shaped adhesive 43. In addition, (not shown here) an adhesive bond can also be provided between the respectively adjacent cardboard frame walls 5 and 13 or 7 and 15.

Die Deckelklappe 28, die an der mit dem inneren Faltkarton 2 verklebten Kartonzargenwand 6 des äußeren Faltkartons 1 faltbar angelenkt ist, weist eine auftrennbare Zugangsöffnung 44 auf. Auch in der darunter angeordneten Deckelklappe 36 des inneren Faltkartons 2 ist eine entsprechende auftrennbare Zugangsöffnung 45 vorgesehen. Nach dem Auftrennen der Zugangsöffnungen 44 und 45 wird der Zugang zu dem darunter angeordneten Entnahmeverschluss 3 des Folieninnenbeutels 4 freigegeben.The cover flap 28, which is hinged foldably on the cardboard folding wall 6 of the outer folding carton 1 glued to the inner folding carton 2, has a separable access opening 44. A corresponding separable access opening 45 is also provided in the lid flap 36 of the inner folding carton 2 arranged underneath. After the separation of the access openings 44 and 45, access to the removal closure 3 of the inner film bag 4 arranged underneath is released.

Wie aus der Darstellung des Zuschnitts in Fig. 7 zu ersehen ist, sind die Kartonzargenwände 13, 14, 15 und 16 des inneren Faltkartons 2 an den Zargenkanten 17, 18, 19 und 20 über Kartonbrücken 46 faltbar miteinander verbunden, die jeweils einen Kantenschlitz 47 überbrücken. Dadurch wird eine besonders flexible Ausführung des inneren Faltkartons 2 erreicht, so dass er sich nicht nur im aufgerichteten Zustand (Fig. 1 - 6), sondern auch im flachliegend zusammengefalteten Zustand (Fig. 9) gut an den äußeren Faltkarton 1 anpasst.As from the representation of the blank in Fig. 7 can be seen, the Kartonzargenwände 13, 14, 15 and 16 of the inner folding carton 2 at the Zargenkanten 17, 18, 19 and 20 via cardboard bridges 46 are connected to each other foldable, each bridging an edge slot 47. As a result, a particularly flexible design of the inner folding carton 2 is achieved that he is not only in the erected state ( Fig. 1 - 6 ), but also in the flat folded state ( Fig. 9 ) adapts well to the outer folding carton 1.

Die Oberkanten 31 und 33 der beiden einander gegenüberliegenden, mit jeweils einer faltbar angelenkten Deckelklappe 35, 37 versehenen Kartonzargenwände 13 und 15 des inneren Faltkartons 2 liegen im fertiggestellten Zustand tiefer als die Oberkanten 23, 24, 25 und 26 der Kartonzargenwände 5, 6, 7 und 8 des äußeren Faltkartons 1. Damit wird erreicht, dass sich die Deckelklappen 35 und 37 dachförmig auf den gefüllten Folieninnenbehälter 4 legen.The upper edges 31 and 33 of the two opposite, each provided with a foldable hinged lid flap 35, 37 provided Kartonzargenwände 13 and 15 of the inner folding carton 2 are lower than the upper edges 23, 24, 25 and 26 of the cardboard frame walls 5, 6, 7 in the finished state and 8 of the outer folding carton 1. This ensures that the cover flaps 35 and 37 put roof-shaped on the filled film inner container 4.

Der schräge Verlauf der Deckelklappen 35 und 37 erhöht die Stabilität der fertiggestellten Kartonverpackung merklich. Zusätzlich bilden die schrägen Deckelklappen 35 und 37 einen trichterförmigen Abschluss, der die Flüssigkeit in Richtung des Entnahmeverschlusses führt. Zudem werden durch den schrägen Verlauf der Deckelklappen 35 und 37 rechtwinkelige Ecken der Kartonverpackung vermieden.The oblique course of the cover flaps 35 and 37 increases the stability of the finished cardboard packaging noticeably. In addition, the sloping top flaps 35 and 37 form a funnel-shaped end, which leads the liquid in the direction of the removal closure. In addition, 35 and 37 rectangular corners of the cardboard packaging are avoided by the oblique course of the lid flaps.

In Fig. 10 wird zur Veranschaulichung eine Schnittansicht der in Fig. 1 dargestellten Kartonverpackung längs der Ebene X-X dargestellt. In oberen Bereichen 50 können in dem äußeren Faltkarton 1 perforierte Grifflöcher vorgesehen sein. Eine Handhabung der Kartonverpackung wird dann wesentlich erleichtert, da im Innenraum im Bereich der Grifflöcher weder ein innerer Faltkarton 2 noch ein Folieninnenbeutel 4 eng anliegend angeordnet sind und ausreichend Platz für einen Eingriff besteht.In Fig. 10 is a sectional view of the in Fig. 1 shown carton packaging along the plane XX. In upper regions 50, perforated gripping holes can be provided in the outer folding carton 1. A handling of the cardboard packaging is then substantially facilitated, since in the interior of the handle holes neither an inner folding carton 2 nor a film inner bag 4 are arranged tight-fitting and there is sufficient space for engagement.

Bei dem dargestellten Ausführungsbeispiel besteht der äußere Faltkarton 1 und der innere Faltkarton 2 jeweils aus einem gesonderten Kartonzuschnitt, die in den Fig. 8 bzw. 7 dargestellt sind. Stattdessen kann auch vorgesehen sein, dass der äußere Faltkarton 1 und der innere Faltkarton 2 aus einem gemeinsamen Kartonzuschnitt bestehen. Ebenfalls ist denkbar, dass der äußere Faltkarton 1 und/oder der innere Faltkarton 2 aus zwei oder mehreren Kartonzuschnitten bestehen.In the illustrated embodiment, the outer folding carton 1 and the inner folding carton 2 each consist of a separate carton blank, which in the Fig. 8 or 7 are shown. Instead, it can also be provided that the outer folding carton 1 and the inner folding carton 2 consist of a common carton blank. It is also conceivable that the outer folding carton 1 and / or the inner folding carton 2 consist of two or more carton blanks.

Fig. 9 zeigt in einer Stirnansicht eine vorgefertigte Kartoneinheit, wie sie zur Herstellung einer Karton-Flüssigkeitsverpackung der beschriebenen Art bereitgestellt und dem Verwender angeliefert wird. Eine flachliegend zusammengefaltete innere Kartonfalthülse 48, die später den inneren Faltkarton 2 bildet, ist in einer flachliegend zusammengefalteten äußeren Kartonfalthülse 49 angeordnet, die später den äußeren Faltkarton 1 bildet. Die eine Kartonzargenwand 14 der inneren Kartonfalthülse 48 ist mit der benachbarten Kartonzargenwand 6 der äußeren Kartonfalthülse 49 verklebt. Fig. 9 shows in a front view of a prefabricated carton unit, as provided for the production of a carton liquid packaging of the type described and delivered to the user. A flat folded inner cardboard folding sleeve 48, which later forms the inner folding carton 2, is arranged in a flat folded outer carton folding sleeve 49, which later forms the outer folding carton 1. The one cardboard frame wall 14 of the inner cardboard folding sleeve 48 is adhesively bonded to the adjacent cardboard frame wall 6 of the outer cardboard folding sleeve 49.

Aus dem in Fig. 9 schematisch dargestellten, flachliegend gefalteten Zustand kann die vorgefertigte Kartoneinheit in einfacher Weise aufgerichtet werden. Nach dem Einsetzen und Befüllen des Folieninnenbeutels 4 wird die Flüssigkeitsverpackung in der Weise verschlossen, wie dies in den Fig. 3 - 6 dargestellt ist. Zunächst werden die beiden Deckelklappen 35 und 37 schräg auf den Folieninnenbeutel 4 geklappt (Fig. 3). Dann werden die beiden anderen Deckelklappen 36 und 38 des inneren Faltkartons 2 nach innen gefaltet (Fig. 4). Darüber werden die Deckelklappen 27 und 29 des äußeren Faltkartons 1 gelegt (Fig. 5). Schließlich wird die Flüssigkeitsverpackung mittels der Deckelklappen 28 und 30 verschlossen.From the in Fig. 9 schematically shown, lying flat folded state, the prefabricated carton unit can be erected in a simple manner. After insertion and filling of the film inner bag 4, the liquid packaging is closed in the manner as in the Fig. 3 - 6 is shown. First, the two cover flaps 35 and 37 are folded obliquely on the film inner bag 4 ( Fig. 3 ). Then, the two other lid flaps 36 and 38 of the inner folding carton 2 are folded inward ( Fig. 4 ). Above the cover flaps 27 and 29 of the outer folding carton 1 are laid ( Fig. 5 ). Finally, the liquid packaging is closed by means of the cover flaps 28 and 30.

Anstelle einer Flüssigkeit kann auch jedes andere rieselfähige oder zähflüssige Gut in das Folieninnenbehältnis, bzw. den Folieninnenbeutel 4 eingefüllt, transportiert und gelagert sowie wieder entnommen werden. Das Folieninnenbehältnis kann dann in Abhängigkeit von dem aufzunehmenden Gut auch als Beschichtung des inneren Faltkartons 2 ausgeführt sein.Instead of a liquid, any other free-flowing or viscous material in the film inner container, or the inner film bag 4 can be filled, transported and stored and removed again. The film inner container can then be designed as a coating of the inner folding carton 2 depending on the material to be absorbed.

Der innere Faltkarton 2 und der äußere Faltkarton 1 sind vorzugsweise aus Wellpappe hergestellt. Es ist jedoch auch denkbar, dass der innere und/oder der äußere Faltkarton 2, 1 aus Kunststoff oder aus einem geeigneten Verbundmaterial hergestellt sind. In Abhängigkeit von dem verwendeten Material für den inneren und äußeren Faltkarton 2, 1 können diese mittels geeigneter Befestigungsmittel oder Befestigungsverfahren miteinander befestigt sein, so dass nicht notwendigerweise ein Kleber verwendet werden muss.The inner folding carton 2 and the outer folding carton 1 are preferably made of corrugated cardboard. However, it is also conceivable that the inner and / or the outer folding carton 2, 1 are made of plastic or of a suitable composite material. Depending on the material used for the inner and outer folding carton 2, 1 can these are fastened together by means of suitable fastening means or fastening methods, so that an adhesive does not necessarily have to be used.

In den meisten vorangehend beschriebenen Ausführungsbeispielen kann durch eine geeignete Ausgestaltung der Dimensionierung in Verbindung mit den verwendeten Materialien eine Kartonverpackung hergestellt werden, welche die gängigen Sicherheitsanforderungen für den Transport und die Lagerung von Gefahrgut erfüllen und dennoch maschinengängig sind, also auf einer automatischen Abfüllanlage verwendet werden können.In most embodiments described above can be prepared by a suitable design of the dimensioning in conjunction with the materials used a cardboard packaging that meet the usual safety requirements for the transport and storage of dangerous goods and yet are machine accessible, so can be used on an automatic bottling plant ,
