This is adapted to the outer contours of the sealing edge corners of the outer container, and is welded to the folded edge in the corners. The reinforcement consists of reinforcing corners (12) or an all-round frame. The front edge (13) and the neighboring parts of the side edges (14) of the folded edge are connected to a rolled-up foil apron (15), which may be rolled out.

Description

Die Erfindung betrifft einen Behälter für Sonderabfall- und Gefahrguttransport mit einem Außenbehälter, der an seiner Behälteröffnung einen umlaufenden Dichtrand aufweist und durch einen Deckel mittels Schließvorrichtungen fest verschließbar ist, und mit einem im Außenbehälter angeordneten, auswechselbaren Folieninnenbehälter mit einem konfektionierten, an die Form des Dichtrandes angepaßten Umschlagrand.The invention relates to a container for hazardous waste and dangerous goods transport with an outer container, which has a circumferential sealing edge at its container opening and can be firmly closed by a lid by means of closing devices, and with an interchangeable film inner container arranged in the outer container with a made to the shape of the sealing edge customized cover edge.

Derartige Behälter dienen zum Transport von Sonderabfall und Gefahrgut, das beispielsweise in staubfähiger, rieselfähiger, pastöser oder flüssiger Form und oftmals auch als Gemisch hiervon vorliegt. Teilweise ist der aufzunehmende Behälterinhalt heiß.Containers of this type are used to transport hazardous waste and hazardous goods, which are present, for example, in a dusty, pourable, pasty or liquid form and often also as a mixture thereof. The contents of the container are sometimes hot.

Bei einem bekannten Behälter der eingangs genannten Gattung (WO 97/18147) ist der konfektionierte Umschlagrand des Folieninnenbehälters so an die Form des Dichtrandes angepaßt, daß er nach dem Einsetzen in den Außenbehälter glatt und faltenfrei auf dem Dichtrand des Außenbehälters aufliegt.In a known container of the type mentioned (WO 97/18147), the assembled envelope edge of the inner film container is adapted to the shape of the sealing edge in such a way that it lies smoothly and wrinkle-free on the sealing edge of the outer container after insertion into the outer container.

Bei der Aufnahme von heißem Behälterinhalt ist jedoch diese faltenfreie Auflage des Umschlagrandes auf dem Dichtrand des Außenbehälters nicht immer gewährleistet, weil der Folieninnenbehälter und auch sein Umschlagrand unter der Hitzeeinwirkung schrumpft. Zwar wird hierfür bei der Bemessung des Folieninnenbehälters eine Schrumpfreserve vorgesehen, die aber wiederum nicht zu groß gewählt werden darf, da sonst eine faltenfreie Auflage des Umschlagrandes auf dem Dichtrand in kaltem Zustand nicht gewährleistet ist. Überschreitet die Abmessungsänderung infolge der Hitzeeinwirkung bei der Aufnahme von heißem Behälterinhalt diese Schrumpfreserve, so besteht die Gefahr, daß der Umschlagrand seine an den Dichtrand angepaßte Form und Abmessungen verliert und nicht mehr glatt aufliegt und herabgezogen wird. Dann ist ein dichter Abschluß mit dem Deckel und insbesondere einem aus Folie bestehenden Deckelüberzug nicht mehr gewährleistet. Außerdem ist durch die Verschweißung der Faltenbildung an den Ecken keine ausreichende Dichtwirkung zu erzielen. Hinzu kommt, daß die Falten beim Schweißvorgang perforiert werden.When hot container contents are taken in, however, this wrinkle-free support of the envelope edge on the sealing edge of the outer container is not always guaranteed, because the film inner container and its envelope edge shrink under the influence of heat. Although a shrink reserve is provided for this when dimensioning the inner film container, this in turn does not can be chosen large, otherwise a wrinkle-free support of the cover edge on the sealing edge in cold condition is not guaranteed. If the change in dimension due to the effect of heat when receiving hot container contents exceeds this shrink reserve, there is a risk that the envelope edge loses its shape and dimensions adapted to the sealing edge and no longer lies flat and is pulled down. Then a tight seal with the cover and in particular a cover made of film is no longer guaranteed. In addition, a sufficient sealing effect cannot be achieved by welding the folds at the corners. In addition, the folds are perforated during the welding process.

Bei einem Wasserbehälter mit Inliner ist es bekannt (GB-A-2 155 529), den geraden oberen Rand des Inliners mit einem schürzenartigen Fortsatz an einer Kappe zu verbinden, die auf den oberen Rand des Wasserbehälters aufgesetzt wird. Durch diese Verbindung wird der obere Rand des Inliners in Position gehalten, erfährt jedoch keine Verstärkung.In the case of a water container with an inliner, it is known (GB-A-2 155 529) to connect the straight upper edge of the inliner to an apron-like extension on a cap which is placed on the upper edge of the water container. This connection holds the upper edge of the liner in place, but does not experience any reinforcement.

Aufgabe der Erfindung ist es, einen Behälter der eingangs genannten Gattung so auszubilden, daß sowohl im kalten Zustand als auch bei der Aufnahme von heißem Behälterinhalt und dabei auftretender erheblicher Folienschrumpfung eine glatte Auflage des Umschlagrandes auf dem Dichtrand des Außenbehälters sichergestellt ist.The object of the invention is to design a container of the type mentioned in such a way that a smooth support of the envelope edge on the sealing edge of the outer container is ensured both in the cold state and when receiving hot container content and the resulting considerable shrinkage of the film.

Diese Aufgabe wird erfindungsgemäß durch einen Behälter mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved according to the invention by a container with the features of claim 1.

Diese Randverstärkung gewährleistet einen einwandfreien Sitz des Umschlagrandes auf dem Dichtrand und die faltenfreie Verschweißung der Eckkonturen im Bereich der Behälterdichtflächen. Insbesondere sichert die Randverstärkung die Formbeständigkeit des Folieninnenbehälters nach einer Heißbefüllung. Die Verstärkungsecken oder der Verstärkungsrahmen wirken infolge ihres festen Sitzes auf den Dichtrandecken des Außenbehälters einer Schrumpfung entgegen, die über die Schrumpfreserve hinausgeht, die bei der Bemessung des Folieninnenbehälters vorgesehen wurde. Außerdem vereinfachen und erleichtern die mit dem Umschlagrand des Folieninnenbehälters verbundenen Verstärkungsecken oder der Verstärkungsrahmen die Handhabung des Folieninnenbehälters beim Einsetzen in den Außenbehälter und definieren den genauen Sitz des Inliners. Das ist besonders wichtig, um das paßgenaue Ausfüllen der Eckbereiche im Außenbehälter zu gewährleisten.This edge reinforcement ensures a perfect fit of the envelope edge on the sealing edge and the crease-free welding of the corner contours in the area of the container sealing surfaces. In particular, the edge reinforcement ensures the dimensional stability of the inner film container after hot filling. The reinforcement corners or the reinforcement frame counteract shrinkage due to their tight fit on the sealing edge ceilings of the outer container, which goes beyond the shrinkage reserve that was provided in the dimensioning of the film inner container. In addition, the reinforcement corners or the reinforcement frame connected to the envelope edge of the inner film container simplify and facilitate the handling of the inner film container when inserted into the outer container and define the exact fit of the inliner. This is particularly important to ensure that the corner areas in the outer container are filled precisely.

Da beim Entleeren des Behälters eine Kontaminierung des Außenbehälters vermieden werden muß, ist bei dem bekannten Behälter vorgesehen, daß der Umschlagrand an zwei gegenüberliegenden Seiten an jeweils einer Schwächungslinie aufreißbar ist. Dadurch kann ein Teil des Umschlagrandes vor dem Entleeren hochgeklappt und als Schürze über ein benachbartes Rahmenteil gelegt werden, um dessen Verunreinigung beim Entleeren zu vermeiden. Bei der praktischen Handhabung hat sich jedoch gezeigt, daß diese Maßnahme nicht ausreicht, um eine Verunreinigung zu vermeiden. Außerdem kann durch das seitliche Aufreißen des Umschlagrandes und eines oberen Abschnitts des Folieninnenbehälters auf beiden Seiten jeweils eine Öffnung entstehen, durch die wiederum eine Verunreinigung des Außenbehälters erfolgen kann. Die Außenbehältermaße lassen nur eine begrenzte Höhe des Randes zu, so daß bei keinem der bekannten Außenbehälter die Randhöhe eine Schürzenlänge ergibt, welche zur Überdeckung der Lastaufnahmeecken ausreicht.Since contamination of the outer container must be avoided when emptying the container, it is provided in the known container that the edge of the envelope can be torn open on two opposite sides, each on a line of weakness. As a result, part of the edge of the envelope can be folded up before emptying and placed as an apron over an adjacent frame part in order to avoid its contamination during emptying. In practical use, however, it has been shown that this measure is not sufficient to avoid contamination. In addition, by tearing open the edge of the envelope and an upper section of the inner film container on both sides an opening is created, which in turn can contaminate the outer container. The outer container dimensions allow only a limited height of the edge, so that in none of the known outer containers the edge height gives an apron length which is sufficient to cover the load-carrying corners.

Deshalb kann als weitere Ausgestaltung vorgesehen sein, daß der mit den Verstärkungsecken oder dem Verstärkungsrahmen versehene Umschlagrand des Folieninnenbehälters an einer Frontkante und an jeweils einem anschließenden Abschnitt der beiden benachbarten Seitenkanten mit einer aufgerollten, abrollbaren Folienschürze verbunden ist.It can therefore be provided as a further embodiment that the envelope edge of the inner film container provided with the reinforcing corners or the reinforcing frame is connected to a rolled-up, unrollable film apron at a front edge and at a subsequent section of the two adjacent side edges.

Voraussetzung für die Verwendung einer solchen um zwei benachbarte Ecken verlaufenden Folienschürze ist der konturgetreue Sitz des Umschlagrandes des Folieninnenbhälters auf dem Dichtrand des Außenbehälters nach der Befüllung und Wiederöffnung des Behälters. Diese Voraussetzung wird durch die Verwendung der Verstärkungsecken oder des umlaufenden Verstärkungsrahmens erfüllt.A prerequisite for the use of such a film apron running around two adjacent corners is that the envelope edge of the inner film container fits correctly on the sealing edge of the outer container after the container has been filled and reopened. This requirement is met by using the reinforcement corners or the circumferential reinforcement frame.

Außerdem haben die Verstärkungsecken oder der Verstärkungsrahmen eine Funktion als Distanzhalter an den Eckbereichen. Sie halten die aufgerollte Folienschürze im Abstand zum Außenbehälter und bilden eine Wärmeisolation, die dafür sorgt, daß die im zusammengerollten Zustand um die beiden Ecken verlaufende Folienschürze nicht durch die Temperatureinwirkung zusammenbackt. Im aufgerollten Zustand stört die Folienschürze beim Befüllen, Verschließen und beim Transport des Behälters nicht. Vor dem Entleeren wird die Folienschürze abgerollt und dient dazu, eine Verunreinigung des Behälters beim Entleerungsvorgang zu verhindern. Die Folienschürze wird über die benachbarten Teile des Außenbehälters einschließlich der an den Ecken angebrachten Lastaufnahmestützen gezogen. Damit ergibt sich eine lückenlose Abdeckung aller Behälterteile im Entleerungsbereich und auch eine aus Folie bestehende Ausgußschürze (Schnauze).In addition, the reinforcement corners or the reinforcement frame have a function as a spacer at the corner areas. They keep the rolled-up film apron at a distance from the outer container and form a thermal insulation which ensures that the rolled-up film apron which runs around the two corners does not cake due to the effects of temperature. When rolled up, the foil apron does not interfere with filling, closing and transporting the container. Before emptying the Foil apron unrolled and serves to prevent contamination of the container during the emptying process. The foil apron is pulled over the neighboring parts of the outer container including the load-bearing supports attached to the corners. This results in complete coverage of all container parts in the emptying area and also a pouring apron (snout) consisting of foil.

Da die Folienschürze zusätzlich an den Umschlagrand angeschlossen ist, verändert der Umschlagrand seine Lage und Beschaffenheit nicht, wenn die Folienschürze verwendet wird. Insbesondere ist es nicht erforderlich, den Umschlagrand einzureißen. Der Umschlagrand behält daher auch beim Entleerungsvorgang seine den oberen Bereich des Außenbehälters schützende Funktion. Die Folienausgußschürze kann fertigungstechnisch eine einseitige Verlängerung des Umschlagrandes sein, aber auch angesetzt werden. Solche Außenbehälter können unterschiedliche umlaufende Profile eines Dichtungsrandes aufweisen.Since the film apron is also connected to the cover edge, the cover edge does not change its position and nature when the film apron is used. In particular, it is not necessary to tear the cover edge. The envelope edge therefore retains its protective function in the upper area of the outer container even during the emptying process. In terms of manufacturing technology, the foil pouring apron can be a one-sided extension of the envelope edge, but can also be attached. Such outer containers can have different circumferential profiles of a sealing edge.

Der Folieninnenbehälter wird zusammengelegt angeliefert; d.h. sein Rand bildet einen Rahmen, in den der übrige Behälter hineingefaltet ist.At the upper edge of the inner film container 9 there is a ready-made envelope edge 10 which is adapted to the shape of the sealing edge 3. The envelope edge 10 lies wrinkle-free on the sealing edge 3 of the outer container 1 when the inner film container 9 is inserted into the outer container 1. The outer edge 10a of the envelope edge 10 hangs down on the outside of the sealing edge 3. The inner film container is delivered folded; i.e. its edge forms a frame into which the rest of the container is folded.

Der Deckel 4 ist mit einem aus Folie bestehenden Deckelüberzug 11 versehen, der nach Art einer flachen Tasche ausgeführt ist, die mindestens an einer Seitenkante 11a offen ist. Diese einseitig offene, flache Tasche wird in der in Fig. 6 angedeuteten Weise über den Deckel 4 gezogen und bedeckt die Oberseite und die Unterseite des Deckels 4.The cover 4 is provided with a cover cover 11 made of film, which is designed in the manner of a flat pocket which is open at least on one side edge 11a. This flat pocket, open on one side, is shown in FIG. 6 indicated manner drawn over the lid 4 and covered the top and bottom of the lid 4th

Der auf dem Dichtrand 3 des Außenbehälters 1 aufliegende Umschlagrand 10 des Folieninnenbehälters 9 ist an seinen vier Eckbereichen jeweils mit einer Verstärkungsecke 12 versehen, die vorzugsweise als Kunststoffteil ausgebildet und mit dem Umschlagrand 10 verschweißt ist. Die Verstärkungsecken 12 sind an die Außenkontur der Dichtrandecken des Außenbehälters 1 angepaßt, wie man insbesondere aus den Fig. 2 und 3 erkennt. Der Außenbehälter 1 weist einen profilierten, durch ein Hohlprofil 1a gebildeten Rand auf, über den die Verstärkungsecken 12 passen.The envelope edge 10 of the film inner container 9 resting on the sealing edge 3 of the outer container 1 is provided at its four corner regions with a reinforcing corner 12, which is preferably designed as a plastic part and is welded to the envelope edge 10. The reinforcing corners 12 are adapted to the outer contour of the sealing edge corners of the outer container 1, as can be seen in particular from FIGS. 2 and 3. The outer container 1 has a profiled edge formed by a hollow profile 1a, over which the reinforcing corners 12 fit.

Wenn der Deckel 4 auf den Dichtrand 3 des Außenbehälters 1 aufgelegt und mittels der Schließvorrichtungen 6 festgespannt ist, drückt die Dichtung 8 des Deckels 4 den Deckelüberzug 11 gegen den auf den Dichtrand 3 faltenfrei aufliegenden Umschlagrand 10 einschließlich der verschweißten Verstärkungsecken 12 oder eines (später noch beschriebenen) umlaufenden Verstärkungsrahmens, so daß ein dichter Verschluß des Folieninnenbehälters 9 sichergestellt ist.When the lid 4 is placed on the sealing edge 3 of the outer container 1 and is tightened by means of the closing devices 6, the seal 8 of the lid 4 presses the lid covering 11 against the envelope edge 10 lying on the sealing edge 3 without creases, including the welded reinforcing corners 12 or one (later described) surrounding reinforcing frame, so that a tight closure of the film inner container 9 is ensured.

An einer Frontkante 13 und jeweils einem anschließenden Abschnitt der beiden benachbarten Seitenkanten 14 (Fig. 1) ist eine aufgerollte Folienschürze 15 angeordnet, die mit dem Umschlagrand 10 verbunden ist. Die Folienschürze 15 kann an den Umschlagrand 10 angeschweißt oder angeklebt oder mit diesem einstückig aus Folie ausgeführt sein.A rolled-up film apron 15, which is connected to the cover edge 10, is arranged on a front edge 13 and in each case a subsequent section of the two adjacent side edges 14 (FIG. 1). The film apron 15 can be welded or glued to the cover edge 10 or be made in one piece with the film.

Wie in Fig. 2 gezeigt, liegt die Folienschürze 15 in ihrem aufgerollten Zustand in den beiden Eckbereichen außen an den Verstärkungsecken 12 bzw. dem Verstärkungsrahmen an und wird auf diese Weise im Abstand zu dem den Dichtrand 3 bildenden Hohlprofils 1a des Außenbehälters 1 gehalten.As shown in FIG. 2, the film apron 15 lies in its rolled-up state in the two corner areas on the outside against the reinforcement corners 12 or the reinforcement frame and is thus kept at a distance from the hollow profile 1 a forming the sealing edge 3 of the outer container 1.

Fig. 4 zeigt am Beispiel eines mit gestrichelten Linien nur angedeuteten Außenbehälters 1 mit abgerundeten Ecken, daß die Verstärkungsecken 12 in entsprechender Weise abgerundet ausgeführt sind. In Fig. 5 ist dargestellt, daß bei abgeschrägten Ecken des Außenbehälters 1 auch die Verstärkungsecken 12' in entsprechender Weise gestaltet sind.FIG. 4 shows, using the example of an outer container 1 with rounded corners, which is only indicated by broken lines, that the reinforcing corners 12 are rounded in a corresponding manner. In Fig. 5 it is shown that the reinforcing corners 12 'are designed in a corresponding manner in the case of bevelled corners of the outer container 1.

Wenn der Behälter entleert werden soll, wird die Folienschürze 15 abgerollt und in der in den Fig. 6 und 7 dargestellten Weise über benachbarte Rahmenteile 16 und insbesondere Stapelecken 17 gelegt. Dadurch werden diese Teile beim Ausgießen des Behälterinhalts vor Verunreinigung geschützt.When the container is to be emptied, the film apron 15 is unrolled and placed in the manner shown in FIGS. 6 and 7 over adjacent frame parts 16 and in particular stacking corners 17. This protects these parts from contamination when pouring out the contents of the container.

Nach dem Öffnen und Entleeren des Behälters können der Folieninnenbehälter 9 und der Deckelüberzug 11 abgenommen werden. Der Außenbehälter 1 und insbesondere der Deckel 4 bleiben damit weitgehend frei von Verunreinigungen, so daß Reinigungsarbeiten nicht oder nur in sehr geringem Umfang erforderlich sind.After opening and emptying the container, the inner film container 9 and the cover 11 can be removed. The outer container 1 and in particular the lid 4 thus remain largely free of impurities, so that cleaning work is not necessary or only to a very small extent.

Bei dem dargestellten Ausführungsbeispiel bestehen der Folieninnenbehälter 9 und sein Umschlagrand 10 einteilig aus dem gleichen Folienmaterial. Da die Auswahl des Folienmaterials in einem weiten Bereich an die mechanischen, thermischen und/oder chemischen Anforderungen des jeweiligen Einsatzfalles angepaßt werden können, kann es insbesondere bei hochtemperaturbeständigen Folien zweckmäßig sein, den Umschlagrand 10 aus einem anderen, thermisch verformbaren Folienmaterial auszuführen.In the illustrated embodiment, the inner film container 9 and its envelope edge 10 are made in one piece from the same film material. Since the selection of the film material in a wide range to the mechanical, thermal and / or chemical requirements of the respective application can be adapted, it may be expedient, in particular in the case of high-temperature-resistant foils, to carry out the cover edge 10 from a different, thermally deformable foil material.

Auch wenn der aufzunehmende Behälterinhalt so heiß ist, daß die dadurch verursachte Schrumpfung des Folieninnenbehälters 9 das Maß der vorgesehenen Schrumpfreserve überschreitet, wird der Umschlagrand 10 des Folieninnenbehälter 9 durch die daran angebrachten Verstärkungsecken 12 in seiner glatt abschließenden Lage auf dem Dichtrand 3 des Außenbehälters 1 gehalten. Auch die beim Entleeren des Behälterinhalts über die Folienschürze 15 ausgeübten Zugkräfte können wegen der Haltewirkung der Verstärkungsecke 12 die Lage des Umschlagrandes 10 nicht verändern. Abweichend von dem in den Fig. 1 - 7 dargestellten Ausführungsbeispiel ist in den Fig. 8 und 9 gezeigt, daß die Randverstärkung des Folieninnenbehälters 9 auch aus einem umlaufenden Verstärkungsrahmen 12' bestehen kann, der in gleicher Weise wie die vorher beschriebenen Verstärkungsecken 12 auf den Umschlagrand 10 aufgesetzt und mit diesem verbunden, beispielsweise verschweißt ist.Even if the container content to be accommodated is so hot that the resulting shrinkage of the inner film container 9 exceeds the intended shrink reserve, the envelope edge 10 of the inner film container 9 is held in its smoothly sealed position on the sealing edge 3 of the outer container 1 by the reinforcing corners 12 attached to it , Even the tensile forces exerted on the foil apron 15 when emptying the contents of the container cannot change the position of the envelope edge 10 because of the holding effect of the reinforcing corner 12. 8 and 9 it is shown that the edge reinforcement of the film inner container 9 can also consist of a circumferential reinforcement frame 12 ', which in the same way as the previously described reinforcement corners 12 on the Cover edge 10 placed and connected to it, for example welded.

Fig. 8 zeigt eine Ausführungsform ohne Folienschürze. In Fig. 9 ist eine Ausführungsform des Folieninnenbehälters 9 gezeigt, bei der am umlaufenden Verstärkungsrahmen 12 eine Folienschürze 15 in der vorher beschriebenen Weise aufgerollt ist.8 shows an embodiment without a film apron. FIG. 9 shows an embodiment of the film inner container 9 in which a film apron 15 is rolled up on the circumferential reinforcing frame 12 in the manner described above.
