Description

Die vorliegende Erfindung betrifft einen großvolumigen Verpackungsbehälter aus flexiblem Material, vorzugsweise aus Polypropylen Gewebe, mit einer rechteckigen Aufstandsfläche, auf welcher der Verpackungsbehälter in Transportposition lagert, sowie vier Mantelflächen und einer Deckenfläche, zum Transport von Bitumen, wobei Aufstandsfläche, Mantelflächen und Deckfläche jeweils durch Nähte mit der/den benachbarten Fläche(n) verbunden sind, wobei jede Mantelfläche die Form eines Rechtecks aufweist und zumindest eine erste Seitenlänge der Aufstandsfläche um mehr als 80%, bevorzugt um mehr als 100% länger ist als die Höhe des Verpackungsbehälters, gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a large-volume packaging container made of flexible material, preferably of polypropylene fabric, with a rectangular footprint on which the packaging container stored in transport position, and four lateral surfaces and a ceiling surface for transporting bitumen, wherein footprint, lateral surfaces and top surface respectively by seams with the adjacent surface (s) are connected, each lateral surface having the shape of a rectangle and at least a first side length of the footprint is more than 80%, preferably more than 100% longer than the height of the packaging container, according to the preamble of claim 1.

Die wo 2008/018878 A1 betrifft eine Hebetasche für 24 000 Pfund (entspricht ca. 11,9 t) Beladung mit Abmessungen von 8 x 7 x 4,5 ft (entspricht ca. 244 x 213 x 137 cm) oder 8 x 5,5 x 5,5 ft (entspricht ca. 244 x 168 x 168 cm) und mit mehreren Tragbändern. Die Hebetasche ist für Schüttgut bestimmt.The 2008/018878 A1 relates to a lifting bag for 24,000 pounds (equivalent to approximately 11.9 t) loading dimensions of 8 x 7 x 4.5 ft (equivalent to approximately 244 x 213 x 137 cm) or 8 x 5, 5 x 5.5 ft (approximately 244 x 168 x 168 cm) and with multiple straps. The lifting bag is intended for bulk goods.

Der Behälter der US 4 963 037 A weist an einer Seite mehrere schmale Schlaufen zum Heben des Behälters auf sowie Gurte und Ringe zur Stabilisierung.The container of US 4 963 037 A has on one side several narrow loops for lifting the container and straps and rings for stabilization.

Der Behälter der US 5 865 540 A weist eine Trageschlaufe auf, die zwei einander gegenüberliegende Seitenkanten der Deckfläche über deren Außenseite miteinander verbindet und genauso breit ist wie die Seitenkanten lang sind. Länge, Breite und Höhe sind bei diesem Behälter in etwa gleich.The container of US 5,865,540 has a carrying strap which connects two opposite side edges of the top surface on the outside together and is as wide as the side edges are long. Length, width and height are approximately the same for this container.

Der Einsatz von großvolumigen Verpackungsbehältern aus flexiblem Material für den Transport von fließfähigen Materialien, insbesondere Bitumen ist bereits bekannt.The use of large-volume packaging containers made of flexible material for the transport of flowable materials, especially bitumen is already known.

Nachdem Bitumen für Transportzwecke zunächst in formbeständige Behälter abgefüllt wurde, ist man aus Kostengründen dazu übergegangen, diese durch flexible Behälter wie Kleinpackungen aus Kartons bzw. Kunststofffolie zu verpacken. Aber auch dies hat sich aufgrund der geringen Aufnahmekapazität der Kleinpackungen als unwirtschaftlich herausgestellt, weshalb großvolumige verpackungsbehälter aus flexiblem Material zum Transport von Bitumen herangezogen wurden. Diese großvolumigen Verpackungsbehälter konnten einerseits eine ausreichend große Menge an Bitumen aufnehmen um den Transport wirtschaftlich zu gestalten, andererseits waren sie aufgrund ihres Aufbaus auch sehr widerstandsfähig. Sie bestanden und bestehen immer noch aus Polypropylen Gewebe mit einem vorzugsweisen spezifischen Gewicht von 200g/m2. In der Regel aber nicht verpflichtend ist auch einen Innensack vorgesehen, der am Zielort gemeinsam mit dem Bitumen aufgeschmolzen wird.After bitumen was first filled into dimensionally stable containers for transport purposes, it has gone over for cost reasons to pack them by flexible containers such as small packages of cardboard or plastic film. But even this has proved to be uneconomical due to the small capacity of the small packages, which is why bulky packaging container made of flexible material for the transport of bitumen were used. On the one hand, these large-volume packaging containers could hold a sufficiently large quantity of bitumen in order to make the transport economical, but on the other hand they were also very resistant due to their structure. They consisted and still consist of polypropylene fabric with a preferred specific gravity of 200g / m 2 . As a rule, but not mandatory, an inner bag is provided, which is melted together with the bitumen at the destination.

Um diese großvolumigen Verpackungsbehälter trotz des langsamen Fließens von Bitumen auch im erkalteten Zustand stapelbar und damit transportfähig zu machen wird in der AT 9.582 U1 vorgeschlagen, die Mantelflächen solcher großvolumiger Verpackungsbehälter vom unteren Rand ausgehend als Pyramidenstumpfmantel bzw. von einem Pyramidenstumpfmantel stetig in einen Kegelstumpfmantel übergehend zu formen. Dies soll dazu beitragen, dass die Behälterwandung im Zusammenwirken mit dem eingefüllten, fließfähigen Material selbststabilisierend sei und der Verpackungsbehälter in befülltem Zustand aufrecht stehenbleibt, ohne dass spezielle Stützmittel vorgesehen sind.In order to make these large-volume packaging containers stackable and thus transportable, even in the cooled state, despite the slow flow of bitumen AT 9,582 U1 proposed to form the lateral surfaces of such bulky packaging container starting from the lower edge as a truncated pyramid shell or from a truncated pyramid continuous in a truncated cone mantle. This is intended to contribute to the fact that the container wall in cooperation with the filled, flowable material is self-stabilizing and the packaging container remains upright in the filled state without special support means being provided.

In der AT 9 644 U1 wird zusätzlich vorgeschlagen, bei solchen Verpackungsbehältern die Mantelflächen als gleichschenkelige Trapeze auszugestalten. Diese Form der Mantelflächen soll dazu beitragen, dass der Verpackungsbehälter beim Befüllen mit Bitumen selbstaufrichtend ist.In the AT 9 644 U1 is additionally proposed to design the lateral surfaces as isosceles trapezoids in such packaging containers. This shape of the lateral surfaces should help that the packaging container is self-righting when filling with bitumen.

Aus der AT 505.805 B1 ist es zusätzlich bekannt, die Mantelflächen mit Falten, Nähten oder Bändern zu versteifen.From the AT 505,805 B1 It is also known to stiffen the outer surfaces with folds, seams or ribbons.

Die vorgeschlagenen Formen bzw. Hilfsmittel erhöhen zwar die Stabilität eines einzelnen Verpackungsbehälters, werfen aber Probleme bei der Stapelbarkeit auf. So geht beispielsweise bereits beim Nebeneinanderstapeln solcher Verpackungebehälter wertvolles Transportvolumen durch die im wesentlichen konische bzw. pyramidenstumpfförmige Form der Verpackungsbehälter verloren. Andererseits ergeben sich aber auch Probleme beim Übereinanderstapeln solcher Verpackungsbehälter, da die Aufstandsfläche der oberen Verpackungsbehälter größer ist als die Deckenfläche der unteren Verpackungsbehälter und daher der in den oberen Verpackungsbehältern verpackte Bitumen aufgrund seiner Fließeigenschaft bei Transporttemperatur bei längeren Transporten somit die Deckenfläche der jeweils darunter liegenden Verpackungsbehälter umfließt, praktisch also ein Art Haube bildet, wodurch die Entstapelung oft mit beträchtlichen Schwierigkeiten verbunden ist.Although the proposed molds or aids increase the stability of a single packaging container, but pose problems in the stackability. Thus, for example, even in the juxtaposition of such packaging containers valuable transport volume is lost by the substantially conical or truncated pyramidal shape of the packaging container. On the other hand, however, there are also problems when stacking such packaging containers, since the footprint of the upper packaging container is greater than the ceiling surface of the lower packaging container and therefore the packed in the upper packaging containers bitumen due to its flow characteristic at transport temperature for longer transport thus the ceiling surface of each underlying packaging container flows around, thus practically forms a kind of hood, whereby the unstacking is often associated with considerable difficulties.

Es ist daher die Aufgabe der vorliegenden Erfindung, diese Nachteile zu verhindern und einen großvolumigen Verpackungsbehälter aus flexiblem Material zum Transport von Bitumen mit einer rechteckigen Aufstandsfläche, auf welcher der Verpackungsbehälter in Transportposition lagert, sowie vier Mantelflächen und einer Deckfläche, wobei Aufstandsfläche, Mantelflächen und Deckfläche jeweils durch Nähte mit der/den benachbarten Fläche(n) verbunden sind, vorzuschlagen, der nicht nur nach Befüllung in sich selbst stabil ist sondern auch eine verbesserte Stapelbarkeit sowie Transportfähigkeit aufweist.It is therefore an object of the present invention to prevent these disadvantages and a large-volume packaging container made of flexible material for transporting bitumen with a rectangular footprint on which the packaging container stores in transport position, and four lateral surfaces and a top surface, wherein footprint, lateral surfaces and top surface each connected by seams with the / the adjacent surface (s) to propose, which is not only stable after filling in itself but also has improved stackability and transportability.

Erfindungsgemäß wird dies gemäß Anspruch 1 bei einem großvolumigen Verpackungsbehälter aus flexiblem Material dadurch erreicht dass jede Mantelfläche die Form eines Rechtecks aufweist und zumindest eine erste Seitenlänge der Aufstandsfläche um mehr als 80%, bevorzugt um mehr als 100% länger ist als die Höhe des Verpackungsbehälters, sowie
dass die Höhe stets kleiner als 100 cm ist und
dass mindestens eine, vorzugsweise exakt eine erste Tragschlaufe vorgesehen ist, welche zwei einander gegenüberliegende Seitenkanten der Deckfläche über deren Außenseite miteinander verbindet und welche mit der Deckfläche einen Tunnel bildet und die Breite der mindestens einen, vorzugsweise exakt einen, ersten Tragschlaufe bzw. der Gesamtheit der Breiten der Tragschlaufen an der Deckfläche zumindest drei Viertel der Länge der beiden Seitenkanten beträgt, welche sie miteinander verbindet, wobei die Seitenkanten parallel zur ersten Seitenlänge der Aufstandsfläche verlaufen, und
dass eine Füllöffnung in einer der beiden Mantelflächen, vorzugsweise in einer der beiden kleineren Mantelflächen vorgesehen ist.According to the invention this is achieved according to claim 1 in a large-volume packaging container made of flexible material each lateral surface has the shape of a rectangle and at least a first side length of the contact surface is longer than the height of the packaging container by more than 80%, preferably by more than 100%
that the height is always less than 100 cm and
in that at least one, preferably exactly one, first carrying loop is provided, which connects two opposite side edges of the cover surface to each other via the outside thereof and which forms a tunnel with the cover surface and the width of the at least one, preferably exactly one, first carrying loop or the entirety of the Widths of the support loops on the top surface is at least three quarters of the length of the two side edges, which connects them together, wherein the side edges are parallel to the first side length of the footprint, and
a filling opening is provided in one of the two lateral surfaces, preferably in one of the two smaller lateral surfaces.

Aufgrund der rechteckigen Ausgestaltung der Mantelflächen ergibt sich in Kombination mit der rechteckigen Aufstandsfläche eine optimierte Stapelbarkeit sowie die optimale Ausnutzung des für den Transport der Behälter zur Verfügung stehenden Transportraumes.Due to the rectangular configuration of the lateral surfaces results in combination with the rectangular footprint optimized stackability and optimal utilization of the transport space available for the transport of the container.

Das angegebene Verhältnis zwischen einer ersten Seitenlänge der Aufstandsfläche zur Höhe des Verpackungsbehälters bewirkt eine Vergrößerung des Trägheitsmoments um die betroffene Trägheitsachse, bei gleichzeitiger Ausnutzung der verfügbaren Stabilität der Mantelflächen, wodurch ein Umfallen wirkungsvoll verhindert werden kann.The specified ratio between a first side length of the footprint to the height of the packaging container causes an increase in the moment of inertia about the affected axis of inertia, while taking advantage of the available stability of the lateral surfaces, whereby a drop over can be effectively prevented.

Die erfindungsgemäße Kombination des Verhältnisses der ersten Seitenlänge der Aufstandsfläche zur Höhe deThe inventive combination of the ratio of the first side length of the footprint to the height de

Verpackungsbehälters mit der Geometrie der Mantelflächen führt zu einer Abstimmung des Verpackungsbehälters derart, dass das Fließen des Bitumens zu keiner Beeinträchtigung der Stabilität des Behälters führt, da bei Einhaltung der erfindungsgemäßen Verhältnisse bzw. Geometrien die Festigkeit des Materials des Verpackungsbehälters die beim Fließen des Bitumens während des Transports auftretenden Kräfte problemlos aufnehmen kann, ohne sich stabilitätsgefährdend zu verformen. Besonders gute Ergebnisse hinsichtlich Stabilität des Verpackungsbehälters sind zu erzielen, wenn mit zunehmendem Volumen des Verpackungsbehälters die Länge der ersten Seitenlänge im erfindungsgemäßen Bereich reduziert wird. Es hat sich herausgestellt, dass bei Einhalten der erfindungsgemäßen Merkmale die im Stand der Technik als zwingend vorgeschlagene Ausgestaltung der Mantelflächen als gleichschenkelige Trapeze bzw. Ausgestaltung des Behälters als kegelstumpfförmig nicht erforderlich ist, was die Transportierbarkeit stark verbessert. Auch zusätzliche Versteifungen in den Mantelflächen sind bei einem erfindungsgemäßen Verpackungsbehälter nicht notwendig.Packaging container with the geometry of the lateral surfaces leads to a tuning of the packaging container such that the flow of bitumen does not affect the stability of the container, as in compliance with the inventive conditions or geometries, the strength of the material of the packaging container during the flow of the bitumen during the Transports occurring forces can easily without deforming stability endangering. Particularly good results in terms of stability of the packaging container can be achieved if the length of the first side length is reduced in the range according to the invention with increasing volume of the packaging container. It has been found that in compliance with the features according to the invention, the embodiment of the lateral surfaces proposed as mandatory in the prior art as an isosceles trapeze or embodiment of the container as frustoconical is not required, which greatly improves the transportability. Additional stiffeners in the lateral surfaces are not necessary in a packaging container according to the invention.

Unter der Höhe des Verpackungsbehälters ist dessen Höhe in unbefülltem Zustand zu verstehen. Sie entspricht daher der Länge der stehenden Seitenkante einer Mantelfläche in nicht ausgebauchtem Zustand.Under the height of the packaging container whose height is to be understood in the unfilled state. It therefore corresponds to the length of the stationary side edge of a lateral surface in not bulged state.

Gemäß der Erfindung betreffend die Deckfläche und gemäß einer bevorzugten Ausführungsvariante der Erfindung betreffend die Aufstandsfläche ist es vorgesehen, dass mindestens eine erste/zweite Tragschlaufe angeordnet ist, welche zwei einander gegenüberliegende Seitenkanten der Deckfläche/Aufstandsfläche über deren Außenseite miteinander verbindet, wobei die Breite der mindestens einen ersten/zweiten Tragschlaufe bzw. der Gesamtheit der Breiten der Tragschlaufen an der Deckfläche/Aufstandsfläche zumindest drei Viertel der Läng der beiden Seitenkanten beträgt, welche sie miteinander verbindet.According to the invention concerning the top surface and according to a preferred embodiment of the invention relating to the contact surface, it is provided that at least one first / second support loop is arranged, which connects two opposite side edges of the top surface / footprint over the outside thereof, wherein the width of the at least a first / second carrying loop or the entirety of the widths of the carrying loops on the top surface / footprint at least three quarters of the length the two side edges, which connects them together.

Die Tragschlaufen weisen dadurch ausreichend Steifigkeit auf und bilden gemeinsam mit der Deckfläche bzw. der Aufstandsfläche einen Tunnel. Dadurch wird das Einfädeln eines technischen Hebemittels gegenüber Verpackungsbehältern mit weniger breiten und damit weniger formstabilen Tragschlaufen erleichtert.The carrying loops thereby have sufficient rigidity and form a tunnel together with the top surface or the contact surface. As a result, the threading of a technical lifting means over packaging containers with less wide and thus less dimensionally stable carrying loops is facilitated.

Da mit zunehmender Breite einer Tragschlaufe sich auch deren Steifigkeit erhöht und somit die Tunnelform auch im Ruhezustand des Verpackungsbehälters erhalten bleibt, die Trageschlaufe somit nicht in sich zusammenfällt oder umfällt, wird auch in dieser Hinsicht das Einfädeln eines technischen Hebemittels erleichtert. Die Ausbildung des beschriebenen Tunnels bewirkt des weiteren eine gleichmäßigere Lastverteilung sowie eine damit einhergehende geringere Vorformung und Beanspruchung des Verpackungsbehälters.As with increasing width of a support loop also increases their rigidity and thus the tunnel shape is maintained even in the resting state of the packaging container, the support loop thus does not coincide or falls over, the threading of a technical lifting means is facilitated in this regard. The formation of the tunnel described further causes a more uniform load distribution and a concomitant lower preforming and stress of the packaging container.

In einer besonders bevorzugten Ausführungsvariante ist es vorgesehen, dass exakt eine erste Tragschlaufe an der Deckfläche, zwei gegenüberliegende Seiten derselben verbindend, angeordnet ist und exakt eine zweite Tragschlaufe an der Aufstandefläche, ebenfalls zwei gegenüberliegende Seiten derselben verbindend, beide Tragschlaufen mit einer Breite von mindestens drei Viertel der Länge der beiden Seitenkanten. In diesem Fall gestaltet sich das Einfädeln eines technischen Hebemittels als besonders einfach, da das technische Hebemittel lediglich einmal pro Verpackungsbehälter in die Tragschlaufe eingefädelt werden muss.In a particularly preferred embodiment variant, it is provided that exactly one first carrying loop is arranged on the cover surface, connecting two opposite sides thereof, and exactly two second carrying loop on the contact surface, also connecting two opposite sides thereof, both carrying loops with a width of at least three Quarter of the length of the two side edges. In this case, the threading of a technical lifting means designed as particularly simple, since the technical lifting means must be threaded only once per packaging container in the carrying strap.

Bevorzugterweise sind Aufstandsfläche, die Mantelflächen, die Deckfläche sowie die zumindest eine erste/zweite Tragschlaufe aus identischem Material gefertigt, was die Herstellung vereinfacht.Preferably, contact area, the lateral surfaces, the top surface and the at least one first / second support loop made of identical material, which simplifies the production.

Es handelt sich bei den Seitenkanten der Deckfläche, welche durch die mindestens eine erste Tragschlaufe miteinander verbunden sind und den Seitenkanten der Aufstandsfläche, welche über die mindestens eine zweite Tragschlaufe miteinander verbunden sind, um parallel zueinander verlaufende Seitenkanten, so dass der großvolumige Verpackungsbehälter einerseits relativ einfach mittels der Gabel eines Gabelstaplers aufgenommen werden kann, die Tragschlaufen aber auch als Angriffspunkte für Einspann- bzw. Haltemittel dienen können, wenn, wie gemäß der Erfindung, eine Füllöffnung zum Einfüllen von Bitumen in einer der Mantelflächen, vorzugsweise der beiden kleineren Mantelflächen vorgesehen ist. Aufgrund der länglichen, schlauchförmigen Ausgestaltung der erfindungsgemäßen Verpackungsbehälter, bietet die Anordnung der Füllöffnung in einer der beiden kleineren Mantelflächen den Vorteil einer stabileren Befüllungsmöglichkeit entlang der Längsachse des Verpackungsbehälters.It is at the side edges of the top surface, which are interconnected by the at least one first support loop and the side edges of the footprint, which are connected to each other via the at least one second support loop to mutually parallel side edges, so that the bulky packaging container on the one hand relatively simple can be received by the fork of a forklift, but the support loops can also serve as points of attack for clamping or holding means when, as in the invention, a filling opening for filling bitumen in one of the lateral surfaces, preferably the two smaller lateral surfaces is provided. Due to the elongated, tubular configuration of the packaging container according to the invention, the arrangement of the filling opening in one of the two smaller lateral surfaces offers the advantage of a more stable filling possibility along the longitudinal axis of the packaging container.

Um den Befüllungsvorgang zu vereinfachen, kann jede Tragschlaufe in deren der Füllöffnung zugewandetem Endbereich eine Halteöffnung, vorzugsweise in Form einer Halteöse aufweisen, in welche Hebemittel eingreifen können um den Verpackungsbehälter zu heben bzw. durch ziehen der Trageschlaufen in jeweils entgegengesetzte Richtung die Füllöffnung in der Mantelfläche zu öffnen.In order to simplify the filling process, each carrying loop may have a holding opening, preferably in the form of a holding lug, in which lifting means can engage in order to lift the packaging container or by pulling the carrying loops in respectively opposite directions, the filling opening in the lateral surface to open.

Eine besonders stabile Ausführungsform ergibt sich, wenn erfindungsgemäß eine zweite Seitenlänge der Aufstandsfläche um mehr als 25%, vorzugsweise um mehr als 50% kürzer ist als die erste Seitenlänge der Aufstandsfläche und mindestens gleich der Höhe des Verpackungsbehälters.A particularly stable embodiment results when, according to the invention, a second side length of the footprint is more than 25%, preferably more than 50% shorter than the first side length of the footprint and at least equal to the height of the packaging container.

Eine weitere Ausführungsvariante der Erfindung sieht vor, dass zwei einander gegenüberliegende Mantelflächen durch eine Zwischenwand miteinander verbunden sind, welche das Volumen des Verpackungsbehälters in zwei Kammern teilt, wodurch zwei kleinere Einheiten in einen Verpackungebehälter abgefüllt werden können, was Vorteile beim Einschmelzen des Bitumens bringt.A further embodiment variant of the invention provides that two opposing lateral surfaces are interconnected by an intermediate wall which divides the volume of the packaging container into two chambers, whereby two smaller units can be filled into a packaging container, which brings advantages in the melting of the bitumen.

Im Anschluss erfolgt nun eine detaillierte Beschreibung eines Ausführungsbeispiels. Dabei zeigt

Fig.1 zeigt einen aus dem Stand der Technik bekannten großvolumigen Verpackungsbehälter 1 für Bitumen, der eine breite Aufstandsfläche aufweist und mit zunehmender Höhe schmäler wird. Die Mantelflächen sind trapezförmig ausgebildet und sind zwecks zusätzlicher Versteifung mit Nähten versehen. Fig.1 shows a known from the prior art large volume packaging container 1 for bitumen, which has a wide footprint and is narrowing with increasing height. The lateral surfaces are trapezoidal and are provided for the purpose of additional stiffening with seams.

Wie sofort und unmittelbar ersichtlich, ergeben sich aufgrund der Form des Behälters Probleme bei der Stapelbarkeit bzw. beim Transport.As can be seen immediately and immediately, due to the shape of the container, there are problems with stackability and transportation.

Fig.2 zeigt einen befüllten erfindungsgemäßen großvolumigen Verpackungsbehälter 2 bestehend aus einer Aufstandsfläche 3, Mantelflächen 4 sowie einer Deckfläche 5. Jede Mantelfläche 4 weist die Form eines Rechtecks auf, auch ein Quadrat ist daher möglich, so dass sich ein gut stapel- und transportierbarer Verpackungsbehälter ausbildet. Da der Verpackungsbehälter in Fig.2 befüllt dargestellt wurde, weist dieser Ausbauchungen auf, so dass der Anschein entsteht, dass die Mantelfläche keine Rechtecksform aufweisen. Diese Ausbauchungen ergeben sich jedoch aufgrund des Streckvermögens der Mantelflächen. Besonders gut ist die Rechtecksform in unbefülltem zustand zu erkennen. Fig.2 shows a filled inventive large-volume packaging container 2 consisting of a footprint 3, lateral surfaces 4 and a top surface 5. Each lateral surface 4 has the shape of a rectangle, a square is therefore possible, so that forms a well stackable and transportable packaging container. Since the packaging container in Fig.2 filled, this bulges, so that the appearance appears that the lateral surface have no rectangle shape. However, these bulges arise due to the stretchability of the lateral surfaces. The rectangle shape can be seen particularly well when unfilled.

Des weiteren ist zumindest eine erste Seitenlänge (10,11) der Aufstandsfläche um mehr als 50% vorzugsweise um mehr als 80% länger als die Höhe H des Verpackungsbehälters, wodurch der Verpackungsbehälter auch die für den Transport von Bitumen erforderliche Stabilität aufweist, so dass das zäh fließende Bitumen auch nach dem Einfüllen den Verpackungsbehälter nicht zum Umkippen bringen kann.Furthermore, at least a first side length (10,11) of the footprint is more than 50%, preferably more than 80% longer than the height H of the packaging container, whereby the packaging container also has the stability required for the transport of bitumen, so that the Tough flowing bitumen even after filling the packaging container can not cause tipping over.

An der Außenseite der Aufstandsfläche 3, vorzugsweise an deren Seitenkanten 10,11 ist eine erste Tragschlaufe 7 angeordnet. An der Außenseite der Deckfläche 5 vorzugsweise an deren Seitenkanten 8,9 ist eine zweite Tragschlaufe 6 angeordnet. Erste und zweite Tragschlaufen 6,7 verbinden die jeweils einander gegenüberliegende Seitenkanten 8 und 9 bzw. 10 und 11, bei welchen es sich vorzugesweise um die längeren Seitenkanten der Aufstandsfläche/Deckfläche 3,5 handelt.On the outside of the footprint 3, preferably on the side edges 10,11 a first support loop 7 is arranged. On the outer side of the top surface 5, preferably on the side edges 8,9 a second support loop 6 is arranged. First and second carrying loops 6, 7 connect the respective opposite side edges 8 and 9 or 10 and 11, which are preferably the longer side edges of the contact surface / cover surface 3, 5.

Erste und zweite Trageschlaufe 6,7 sind aus dem gleichen Material gefertigt wie der Verpackungsbehälter 2 als solches, nämlich aus Polypropylen Gewebe. Dieser Umstand sowie der Umstand, dass die Breite x der Tragschlaufen 6,7 zumindest ein Viertel, vorzugsweise drei Viertel der Länge der Seitenkanten 8,9 bzw. 10,11 beträgt, trägt dazu bei, dass die Tragschlaufen 6,7 eine hohe Steifigkeit aufweisen und die Aufstandsfläche 3 bzw. die Deckfläche 5 zumindest abschnittsweise tunnelartig überspannen. Insbesondere auch aus der symmetrischen Anordnung der Tragschlaufen 6,7 im Hinblick auf die Längsachse des Verpackungsbehälters 2 ergibt sich eine leichte Einfädelbarkeit von technischen Hebemitteln, beispielsweise der Gabel eines Gabelstaplers.First and second strap 6,7 are made of the same material as the packaging container 2 as such, namely polypropylene fabric. This circumstance and the fact that the width x of the carrying loops 6, 7 is at least a quarter, preferably three quarters, of the length of the side edges 8, 9 and 10, 11 contributes to the fact that the carrying loops 6, 7 have a high rigidity and span the footprint 3 or the top surface 5 at least in sections in a tunnel-like manner. In particular, from the symmetrical arrangement of the carrying straps 6,7 with respect to the longitudinal axis of the packaging container 2 results in easy Einfädelbarkeit of technical lifting means, such as the fork of a forklift.

Eine Füllöffnung 12 ist an einer Mantelfläche 4, vorzugsweise an einer der beiden kleineren Mantelflächen des Verpackungsbehälters 2 ausgebildet. Zwecks Befüllung weist jede Tragschlaufe 6,7 in deren der Mantelfläche 4 mit Füllöffnung 12 zugewandtem Endbereich Halteöffnungen 13 auf, die als Halteösen ausgebildet sein können und auf welchen der Verpackungsbehälter 2 aufgehängt werden kann. Alternativ dazu können auch an den gegenüberliegenden Endbereichen Halteöffnungen 17 vorgesehen sein, um die Handhabbarkeit zu verbessern.A filling opening 12 is formed on a lateral surface 4, preferably on one of the two smaller lateral surfaces of the packaging container 2. For the purpose of filling, each carrying loop 6, 7 has holding openings 13 in its end area facing the lateral surface 4 with filling opening 12, which can be designed as holding eyes and on which the packaging container 2 can be suspended. Alternatively, retaining openings 17 may also be provided at the opposite end regions in order to improve the handling.

Die Füllöffnung 12 ist durch darüber angeordnete Laschen 22,23, die an der die Füllöffnung aufweisenden Mantelfläche 4 ausgebildet sind, abgedeckt. Die Laschen können mittels eines Verschlusses 18 in eine die Füllöffnung 12 abdeckende Position gebracht werden. Zu diesem Zweck ist eine der Laschen 22 mit einer Schlaufe 19 versehen, die mit einem Band 20 an einer weiteren Schlaufe 21 befestigbar ist, die an einer die Mantelfläche 4, welche die Füllöffnung 12 aufweist, begrenzenden Naht angebracht ist. Durch das Verknoten des Bandes 20 ziehen sich die beiden Schlaufen 19 und 21 zusammen und verschließen so über die Laschen 22,23 die Füllöffnung 12.The filling opening 12 is covered by tabs 22, 23 which are formed above and which are formed on the lateral surface 4 having the filling opening. The tabs can be brought by means of a closure 18 in a covering the filling opening 12 position. For this purpose, one of the tabs 22 is provided with a loop 19 which can be fastened with a band 20 to a further loop 21, which is attached to a seam defining the lateral surface 4, which has the filling opening 12. By knotting the band 20, the two loops 19 and 21 pull together and so close over the tabs 22,23 the filling opening 12th

Zusätzlich kann vorgesehen sein, dass zwei einander gegenüberliegende Mantelflächen durch eine Zwischenwand 14 miteinander verbunden sind, welche das Volumen des Verpackungsbehälters 2 in zwei Kammern 15,16 teilt. In diesem Fall sind entsprechend zwei Füllöffnungen (nicht eingezeichnet) vorzusehen.In addition, it can be provided that two mutually opposite lateral surfaces are interconnected by an intermediate wall 14 which divides the volume of the packaging container 2 into two chambers 15, 16. In this case, two filling openings (not shown) are provided accordingly.
