Description

KUNSTSTOFF-FASS PLASTIC BARREL
Die Erfindung betrifft ein Kunststoff-Faß mit im wesent¬ lichen zylindrischer Faßwandung, einem flachen scheiben¬ förmigen Faßunterboden und einem entsprechenden Faßoberboden, in dem gegebenenfalls eine verschließbare Spundlochöffnung angeordnet ist, und mit einem im Nahbereich des Faßoberbodens an der Faßaußenwandung angeordneten, umlaufenden Trage- und Transportring mit nach unten weisender horizontaler und nach innen weisender vertikaler Anlagefläche für die Greiferklauen eines Faßgreifers.The invention relates to a plastic barrel with an essentially cylindrical barrel wall, a flat, disk-shaped barrel bottom and a corresponding barrel top, in which a closable bunghole opening is optionally arranged, and with a circumferential support arranged in the vicinity of the barrel top on the barrel outer wall. and transport ring with downward-facing horizontal and inward-facing vertical contact surface for the gripper claws of a drum gripper.
Übliche Spundfässer mit üblichen Spundlochöffnungen sind ausschließlich für die Lagerung und den Transport von Flüssigkeiten brauchbar; für zähfließende oder partikelför ige Füllgüter sind Spundfässer aufgrund der kleinen Spundlochöffnung (2 Zoll) ungeeignet. Die üblicherweise für die Lagerung und den Transport von zähen oder festen Füllgütern wie z.B. Bitumen, Farbe, Fruchtkonzentrate, Granulate, Schüttgüter oder ähnlichem verwendeten Deckelfässer sind wegen der benötigten Zubehörteile (großer Deckel und Spannringverschluß) ver¬ gleichsweise teuer, insbesondere für einfache Anwendungs¬ fälle wie z.B. den Transport von griesförmigen Produkten wie Kunststoffgranulat (z.B. EPS = Expandible Polystyren) und weisen schlechtere Falleigenschaften als geschlossene Spundfässer auf.Usual bung barrels with usual bunghole openings can only be used for the storage and transport of liquids; Because of the small bunghole opening (2 inches), bung barrels are unsuitable for viscous or particulate products. Usually used for the storage and transport of tough or solid contents such as Bitumen, paint, fruit concentrates, granules, bulk goods or similar used lid drums are comparatively expensive due to the accessories required (large lid and clamping ring closure), especially for simple applications such as e.g. the transport of gritty products such as plastic granulate (e.g. EPS = expandable polystyrene) and have worse falling properties than closed sheet drums.
Es ist Aufgabe der vorliegenden Erfindung ein Kunststoff- Faß anzugeben, das insbesondere für den Transport von zähflüssigen oder griesförmigen Produkten geeignet ist. Das Faß soll kostengünstig herstellbar und zudem mit üb¬ lichen Faßgreiferwerkzeugen handhabbar sein. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß bei einem gattungsmäßigen Kunststoff-Faß zentralmittig im Faßoberboden ein eingesenktes Spundgehäuse mit einem Spundlochstutzen angeordnet ist, wobei der Durchmesser des Spundlochstutzens wenigstens 100 mm oder größer beträgt.It is an object of the present invention to provide a plastic drum which is particularly suitable for the transport of viscous or gritty products. The barrel should be inexpensive to manufacture and, in addition, be able to be handled with conventional barrel gripping tools. This object is achieved in that a recessed bung housing with a bung hole is arranged centrally in the generic top of a generic plastic barrel, the diameter of the bung hole is at least 100 mm or larger.
In einer bevorzugten Ausführungsform ist vorgesehen, daß der Durchmesser des Spundlochstutzens ca. 150 mm beträgt. In einer anderen besonderen Ausführungsform beträgt der Durchmesser des Spundlochstutzens ca. 225 mm. Es ist vorteilhaft, nur diese Durchmessergrößen für alle verschiedenen Faßgrößen (z.B. 120 1, 220 1) gleichermaßen zu verwenden. Das erfindungsgemäße L-Ring-Faß mit dem zentralmittig angeordneten Schraubdeckel ist im Vergleich zu einem üblichen Standard-Deckelfaß kostengünstiger herzustellen und weist demgegenüber bessere Falleigenschaften auf. Die Schraubdeckel sind im Vergleich zu dem großen Faßdeckel ebenfalls wesentlich preisgünstiger herzustellen (da sie auch nur in zwei Größen angeboten werden) , und es entfallen auch die Kosten für einen zusätzlichen Spannring. Damit ist die Möglichkeit gegeben, preisgünstige Schraubdeckelfässer anzubieten, sowohl für den bereits zuvor erwähnten Anwendungsfall für griesförmige Produkte, bzw. Granulate wie auch z.B. für die Abfüllung von stückigen Lebens¬ mitteln oder zähfließenden Fruchtkonzentraten mit ganzen Fruchtstücken. Gegenüber Deckelfässern ergeben sich weiterhin zusätzliche Vorteile, weil die erfindungsgemäs- sen Schraubdeckelfässer mit dem oberen Trage- und Trans¬ portring (Mauser L-Ring) mit den gleichen Faßgreiferwerk¬ zeugen wie für übliche Stahl- oder Kunststoff-Spundfässer manipuliert bzw. gehandhabt werden können. In bevorzugter Ausführungsform ist das Faß vollständig einteilig geblasen. Das Faß kann natürlich auch aus einem im Spritzgußverfahren separat vorgefertigten Oberboden (und ggf. auch Unterboden) mit einem extrudierten zylindrischen Faßkörperrohling aus zwei (oder drei) Teilen zusammengeschweißt werden.In a preferred embodiment it is provided that the diameter of the bunghole is approximately 150 mm. In another special embodiment, the diameter of the bunghole connector is approximately 225 mm. It is advantageous to use only these diameter sizes equally for all different barrel sizes (eg 120 1, 220 1). The L-ring barrel according to the invention with the screw cap arranged in the center is less expensive to produce than a conventional standard lid barrel and, in contrast, has better falling properties. The screw caps are also much cheaper to produce than the large drum caps (since they are only available in two sizes), and there is no need for an additional clamping ring. This makes it possible to offer inexpensive screw-top barrels, both for the aforementioned application for gritty products or granules, and for example for filling lumpy foods or viscous fruit concentrates with whole pieces of fruit. Compared to lid drums, there are further advantages because the screw lid drums according to the invention with the upper carrying and transport ring (Mauser L ring) can be manipulated or handled with the same drum gripper tools as for conventional steel or plastic sheet drums . In a preferred embodiment, the barrel is blown in one piece. The barrel can of course also be welded together from an upper bottom (and possibly also underbody) separately prefabricated by injection molding with an extruded cylindrical barrel body blank made of two (or three) parts.
Weiterhin kann das erfindungsgemäße Faß am unteren Faßrand im Übergangsbereich von äußerer Faßwandung und flachem Faßunterboden auch mit einem umlaufenden stabilen Boden-Rollring ausgestattet sein.Furthermore, the barrel according to the invention can also be equipped with a circumferential stable floor rolling ring on the lower barrel edge in the transition region from the outer barrel wall and flat barrel bottom.
Ein wichtiges Merkmal der Erfindung besteht darin, daß unabhängig vom Fassungsvermögen der L-Ring-Fässer (z.B. 60 1, 120 1, 150 1, 160 1 oder gar 220 1) immer gleiche Abmessungen der zwei bevorzugten Größen des Schraubdeckels bestehen bleiben. Die kleinere Ausführung des Schraubdeckels weist einen Außendurchmesser von ca. 180 mm auf, während der Außendurchmesser des größeren Schraubdeckels ca. 270 mm beträgt.An important feature of the invention is that regardless of the capacity of the L-ring drums (e.g. 60 1, 120 1, 150 1, 160 1 or even 220 1), the same dimensions of the two preferred sizes of the screw cap always remain. The smaller version of the screw cap has an outer diameter of approximately 180 mm, while the outer diameter of the larger screw cap is approximately 270 mm.
Der Spundstutzen weist im vorliegenden Fall ein Außen¬ gewinde für den erfindungsgemäßen mit Innengewinde ausgestatteten Schraubdeckel auf; die üblichen kleinen 2 Zoll-Spundlochstutzen von normalen Spundfässern weisen dagegen immer ein Innengewinde und der zugehörige Spundstopfen ein entsprechendes Außengewinde auf.In the present case, the bung neck has an external thread for the screw cap according to the invention which is equipped with an internal thread; the usual small 2-inch bunghole spigots of normal bung barrels, on the other hand, always have an internal thread and the associated bung plug has a corresponding external thread.
In Ausgestaltung der Erfindung ist vorgesehen, daß die Höhenebene des auf den Spundlochstutzen aufgeschraubten Schraubdeckels in gleicher Höhe bzw. nahezu bündig mit dem Faßoberboden oder unterhalb des Faßoberbodenε angeordnet ist.In an embodiment of the invention it is provided that the height plane of the screw cap screwed onto the bunghole connector is arranged at the same height or almost flush with the top of the barrel or below the top of the barrel.
Der zentralmittig im Faßoberboden in einer Spundmulde versenkt angeordnete Schraubdeckel ist so bei einem Faßabsturz optimal geschützt und kommt bei einem Bodenaufprall in keinem Fall direkt mit dem Boden in Kontakt. Die Erfindung wird nachfolgend anhand von in den Zeich¬ nungen schematisch dargestellten Ausführungsbeispielen näher erläutert und beschrieben. Es zeigen: Figur 1 ein er indungsgemäßes Schraubdeckel-Faß inThe screw cap, which is sunk in the center of the top of the barrel in a bung, is optimally protected in the event of a barrel crash and never comes into direct contact with the floor in the event of a floor impact. The invention is explained and described in more detail below on the basis of exemplary embodiments shown schematically in the drawings. FIG. 1 shows a screw-cap barrel according to the invention

In Figur 1 ist mit der Bezugsziffer 10 ein erfindungsge¬ mäßes Kunststoff-Faß (HOT-Faß) bezeichnet, das eine zylinderförmige Faßwandung 12, einen scheibenförmigen Faßunterboden 14 und einen entsprechenden Faßoberboden 16 aufweist. Im äußeren Übergangsbereich des Faßoberbodens 16 zur Faßaußenwandung 12 ist ein umlaufender Trage- und Transportring 22 mit nach unten weisender horizontaler Anlagefläche 24 und mit nach innen weisender vertikaler Anlagefläche 26 für die Greiferklauen eines für Stahl¬ fässer üblichen Faßgreifers ausgebildet. Zentralmittig im Faßoberboden 16 ist ein eingesenktes Spundgehäuse 28 mit einem vom ebenen Spundgehäuseboden 40 hochstehenden bzw. hervorstehenden Spundlochstutzen 30 mit Außengewinde ausgebildet.In FIG. 1, reference number 10 denotes a plastic barrel (HOT barrel) according to the invention, which has a cylindrical barrel wall 12, a disk-shaped barrel bottom 14 and a corresponding barrel top 16. In the outer transition area of the barrel top 16 to the barrel outer wall 12, a circumferential carrying and transport ring 22 is formed with a downwardly facing horizontal contact surface 24 and with an inwardly facing vertical contact surface 26 for the gripper claws of a barrel gripper that is common for steel drums. In the center of the top of the barrel 16 is a recessed bung housing 28 with one from the flat bung housing bottom 40 upstanding or protruding bunghole connector 30 formed with an external thread.
Der Innendurchmesser des Spundlochstutzens 30 bzw. der Spundlochöffnung 20 (18) beträgt wenigstens 100 mm oder darüber (größer) und ist mittels eines aufgeschraubten Schraubdeckels 34 (32) mit entsprechendem Innengewinde am Flanschrand gas- und flüssigkeitsdicht verschlossen.The inside diameter of the bunghole connector 30 or the bunghole opening 20 (18) is at least 100 mm or more (larger) and is closed in a gas-tight and liquid-tight manner by means of a screw-on screw cap 34 (32) with a corresponding internal thread at the flange edge.
Als kleinster Innendurchmesser des Spundlochstutzens sollten 100 mm nicht unterschritten werden, da die Öffnung wenigstens so groß sein sollte, daß man mit der Hand hineingreifen kann. Diese Mindestöffnungsweite ist natürlich auch für eine vollständige Innenreinigung des Fasses bei Mehrfachverwendung sehr vorteilhaft. Andererseits sollte die Spundlochöffnung aber auch nicht wesentlich größer als der halbe Faßdurchmesser sein; dann geht zum einen der Kostenvorteil verloren und zum anderen kann ggf. die Fallfestigkeit vermindert werden, weil z.B. durch eine starke elastische Ausbeulung des Oberbodens möglicherweise eine Undichtigkeit am Schraubdeckel auftreten könnte.The smallest inside diameter of the bunghole should not be less than 100 mm, since the opening should be at least large enough that you can reach in with your hand. Of course, this minimum opening width is also very advantageous for a complete interior cleaning of the barrel with multiple use. On the other hand, the bunghole opening should not be significantly larger than half the barrel diameter; then on the one hand the cost advantage is lost and on the other hand the drop resistance can be reduced because e.g. a strong elastic bulge in the top floor could possibly cause a leak on the screw cap.
In Figur 2 ist der obere Faßabschnitt mit der größeren Spundlochöffnung 18 mit einem Innendurchmesser des Spundstutzens 30 von ca. 225 mm dargestellt. Hierbei beträgt der Durchmesser des Spundgehäuses gemessen in der Höhenebene des Faßoberbodens zwischen 300 mm und 400 mm, vorzugsweise ca. 330 mm, und der Durchmesser des ebenen Spundgehäusebodens zwischen 250 mm und 330 mm, vorzugs¬ weise ca. 270 mm.FIG. 2 shows the upper barrel section with the larger bunghole opening 18 with an inside diameter of the bung 30 of approximately 225 mm. The diameter of the sheet pile housing measured in the height plane of the barrel top is between 300 mm and 400 mm, preferably approx. 330 mm, and the diameter of the flat sheet pile housing bottom is between 250 mm and 330 mm, preferably approximately 270 mm.
Der größere Schraubdeckel 32 mit einem Außendurchmesser von ca. 270 mm kann auf seiner Oberfläche mit hervor¬ stehenden Ringstegstücken zum Ansetzen eines Schlüssel¬ werkzeuges versehen sein.The larger screw cap 32 with an outer diameter of approximately 270 mm can be provided on its surface with protruding ring web pieces for attaching a key tool.
Die andere bevorzugte Ausführungsform mit der kleineren Spundlochöffnung 20 mit einem Innendurchmesser des Spundstutzens 30 von ca. 150 mm ist in Figur 3 darge¬ stellt. Hierbei beträgt der Durchmesser des Spundgehäuses gemessen in der Höhenebene des Faßoberbodens zwischen 200 mm und 300 mm, vorzugsweise ca. 230 mm, und der Durch¬ messer des ebenen Spundgehäusebodens zwischen 180 mm und 250 mm, vorzugsweise ca. 190 mm.The other preferred embodiment with the smaller bunghole 20 having an inner diameter of The spigot 30 of approximately 150 mm is shown in FIG. 3. Here, the diameter of the sheet pile housing, measured in the height plane of the barrel top, is between 200 mm and 300 mm, preferably approximately 230 mm, and the diameter of the flat sheet pile base is between 180 mm and 250 mm, preferably approximately 190 mm.
Der kleinere Schraubdeckel 34 mit einem Außendurchmesser von ca. 180 mm ist vorzugsweise mit einer flachen Ober¬ fläche versehen. An die flache scheibenförmige Oberfläche der Schraubdeckel schließt sich ein rechtwinkelig abstehender Flanschrand mit einer Höhe von ca. 40 mm an. Außenseitig sind am Flanschrand einige stegartige Noppen bzw. Riffelvorsprünge zum besseren manuellen Greifen beim Verschrauben des Deckels ausgebildet. Der Flanschrand weist ein Innengewinde und der Spundlochstutzen 30 ein entsprechendes Außengewinde auf. Mit geringem Abstand zum Flanschrand ist innenseitig am Schraubdeckel ein zweiter, etwas kürzerer gleichfalls rechtwinkelig abstehender Flanschring ausgebildet. Zwischen dem äußeren Flanschrand und dem inneren Flanschring ist eine umlaufende U-förmige Nut ausgebildet, in welche eine Dichtung eingesetzt ist, die den Schraubdeckel gegen die obere Stirnkante des Spundlochstutzens 30 abdichtet.The smaller screw cap 34 with an outer diameter of approximately 180 mm is preferably provided with a flat surface. The flat, disc-shaped surface of the screw cap is adjoined by a flange edge that protrudes at a right angle and has a height of approx. 40 mm. On the outside, some web-like knobs or corrugated projections are formed on the flange edge for better manual gripping when the cover is screwed on. The flange edge has an internal thread and the bunghole connector 30 has a corresponding external thread. At a short distance from the flange edge, a second, somewhat shorter flange ring also protruding at right angles is formed on the inside of the screw cap. A circumferential U-shaped groove is formed between the outer flange edge and the inner flange ring, into which a seal is inserted, which seals the screw cap against the upper end edge of the bunghole connector 30.
Bei dieser Ausführungsform endet die Höhenebene des auf den Spundlochstutzen aufgeschraubten Schraubdeckels zwischen der Höhenebene des Faßoberbodens und der Höhenebene der oberen Stirnkante des Trage- und Trans¬ portringes 22.In this embodiment, the level of the screw cap screwed onto the bunghole connector ends between the level of the top of the barrel and the level of the upper end edge of the carrying and transport ring 22.
In einer zeichnerisch nicht näher dargestellten Ausführungsform ist die Höhenebene des Faßoberbodens oberhalb der Höhenebene der Stirnkante des Trage- und Transportringes angeordnet.In an embodiment not shown in the drawing, the level of the top of the barrel is arranged above the level of the front edge of the carrying and transport ring.
Hierbei wird auf vorteilhafte Weise bei Übereinander- stapelung gleichartiger Fässer im untergestapelten Faß ein stützender Innendruck aufgebaut bevor die Stapellast in den Trage-und Transportring eingeleitet wird.In this case, when barrels of the same type are stacked one on top of the other in an advantageous manner, in the stacked barrel a supporting internal pressure is built up before the stack load is introduced into the carrying and transport ring.
In Fiαur 4 ist eine weitere erfindungsgemäße Ausführungs¬ form in Teilschnittansicht dargestellt, bei welcher im Faßoberboden 16 zusätzlich seitlich neben der Schraub¬ deckelöffnung (18,20) mit großem Durchmesser eine zweite kleine verschließbare Spundlochöffnung 38 zur Restent¬ leerung des Faßinhaltes vorgesehen ist. Zweckmäßigerweise bleibt diese Spundlochöffnung 38 beim Blasformverfahren zunächst unten (innen) geschlossen ausgebildet. Erst im Bedarfsfall können dann seitliche Bohrungen in den Gewindestutzen eingebracht werden oder es wird das scheibenförmige Bodenstück des Gewindestutzens heraus¬ geschnitten. Die Spundlochöffnung 38 ist mit einem entsprechenden üblichen Spundstopfen verschließbar. Bei der dargestellten Ausführungsform ist die Höhenebene des Faßoberbodens 16 unterhalb der Höhenebene der Stirnkante 36 des Trage- und Transportringes 22 angeordnet, während der Schraubdeckel 34 den Faßoberboden 16 geringfügig überragt.FIG. 4 shows a further embodiment according to the invention in a partial sectional view, in which a second small closable bunghole opening 38 is provided in the top 16 of the barrel in addition to the screw lid opening (18, 20) with a large diameter for emptying the contents of the barrel. Expediently, this bunghole opening 38 initially remains closed at the bottom (inside) during the blow molding process. Lateral bores can then only be drilled into the threaded connector if necessary, or the disk-shaped base piece of the threaded connector is cut out. The bunghole opening 38 can be closed with a corresponding conventional bung plug. In the embodiment shown, the level of the top 16 of the barrel is arranged below the level of the front edge 36 of the carrying and transport ring 22, while the screw cap 34 projects slightly above the top 16 of the barrel.
Bei dieser Ausfuhrungsform erfolgt eine Zentralabstutzung und eine Umfangsabstützung eines übergestapelten gleich¬ artigen Fasses.In this embodiment there is central support and circumferential support of a stacked like barrel.
In abgewandelter Ausfuhrungsform können aber auch die Stirnkante 36 des Trage- und Transportringes 22, der Faßoberboden 16 und der auf den Spundlochstutzen 30 aufgeschraubte Schraubdeckel 32,34 im wesentlichen in gleicher Höhenebene angeordnet sein. In Figur 5 ist eine Draufsicht auf die Faßausführung gemäß Fig. 4 dargestellt. Die zusätzliche Spundloch¬ öffnung 38 kann, muß aber z.B. bei einer Verwendung für granulatförmige Füllgüter nicht unbedingt ausgebildet sein. Bei einer weiterentwickelten Ausführungsform - darge¬ stellt in Figur 6 - ist in den Faßoberboden 16 wenigstens eine radial verlaufende Wasserablauf-Rinne 42 eingeformt, die innenseitig in das Spundgehäuse 28 und außenseitig in die hinter dem Trage- und Transportring 22 in ümfangs- richtung verlaufende Eingreifnut 44 einmündet. Hierdurch wird verhindert, daß sich z.B. größere Regen¬ wassermengen in dem Spundgehäuse 28 ansammeln, wenn ein derartiges Faß im Freien gelagert wird. So kann das sich ansammelnde Regenwasser durch die Rinne 42 aus dem Spund¬ gehäuse 28 in die tieferliegende Eingreifnut 44 hinter dem Trage- und Transportring 22 abfließen. An wenigstens einer Stelle, vorzugsweise an mehreren Stellen, sind durch den Verbindungssteg des Trage- und Transportringes hindurchgehende in den Boden der Eingreifnut 44 einmün¬ dende entsprechende Wasserablauf-Bohrungen angeordnet, so daß sich in der Eingreifnut 44 selbst überhaupt kein Regenwasser ansammeln kann.In a modified embodiment, the end edge 36 of the carrying and transport ring 22, the barrel top 16 and the screw cap 32, 34 screwed onto the bunghole connector 30 can also be arranged essentially at the same height level. FIG. 5 shows a top view of the barrel design according to FIG. 4. The additional bunghole opening 38 can, but does not necessarily have to be formed, for example, when used for granular fillings. In a further developed embodiment - shown in FIG. 6 - at least one radially running water drainage channel 42 is formed in the top 16 of the barrel, the inside of it into the bung housing 28 and the outside into the engagement groove running in the circumferential direction behind the carrying and transport ring 22 44 flows into. This prevents, for example, larger amounts of rain water from accumulating in the bung 28 when such a barrel is stored outdoors. Thus, the rainwater that accumulates can flow through the gutter 42 out of the bung housing 28 into the deeper engaging groove 44 behind the carrying and transport ring 22. At least one location, preferably at several locations, has corresponding water drainage bores flowing through the connecting web of the carrying and transport ring into the bottom of the engaging groove 44, so that no rainwater can collect at all in the engaging groove 44.
In Figur 7 ist ein weiteres erfindungsgemäßes Merkmal realisiert. Um die Restentleerung des Fasses in einer 180° Inversions-Positionierung zu verbessern, ist hier der Faßoberboden 16 insgesamt leicht schräg geneigt, und zwar - in Normalpostition des Fasses betrachtet - auf der Seite der zusätzlichen Restentleerungs-Spundlochöffnung 38 zwischen 2 mm bis 12 mm, vorzugsweise etwa 8 mm, höher als auf der der kleineren Spundlochöffnung 38 gegenüber¬ liegenden Seite ausgebildet.Another feature according to the invention is realized in FIG. In order to improve the residual emptying of the barrel in a 180 ° inversion position, here the barrel top 16 is inclined slightly at an overall angle, namely - viewed in the normal position of the barrel - on the side of the additional residual emptying bunghole 38 between 2 mm and 12 mm, preferably about 8 mm, higher than on the side opposite the smaller bunghole opening 38.
Der Höhenunterschied von etwa 8 mm ist auch in Fig. 4 durch die gestrichelt eingezeichnete Höhenlinie des niedrigen Faßoberbodenbereiches und die rechtwinkelig daran angesetzten Abstandspfeile angedeutet. Bei der ÜbereinanderStapelung derartiger Fässer erfolgt eine Zentralabstutzung über den Schraubdeckel 32 und eine Umfangsabstützung über den Trage- und Transportring 22 des untergestapelten Fasses. Um auch eine Stapelabstützung im Bereich des dazwischen¬ liegenden Faßoberbodens zu erreichen, können, wie in Figur 8 dargestellt ist, entsprechende Aufsatzelemente 46 auf der Oberfläche des Faßoberbodens angeordnet sein. Dabei schließen die Aufsatzelemente 46 jeweils bündig mit dem Trage- und Transportring 22 ab. Bei der in Fig. 8 dargestellten Ausführungsform sind acht gleichmäßig voneinander beabstandete stegförmige Aufsatzelemente 46 vorgesehen. Die Aufsatzelemente können natürlich auch eine andere, z.B. rechteckför ige oder quadratische Form aufweisen und gleich bei der Blasformgebung des Fasses ausgebildet oder später als separat vorgefertigte Spritz¬ gußteile aufgeklebt öder aufgeschweißt werden. Noch einfacher ist die Ausbildung des Faßoberbodnes insgesamt mit Trage- und Transportring, Spundstutzen und Aufsatz- elementen im Spritzgußverfahren, wonach der Faßoberboden auf den Faßkörperrohling aufgeschweißt wird.The height difference of about 8 mm is also indicated in FIG. 4 by the dashed line of contour of the low barrel top area and the spacing arrows attached to it at right angles. When such drums are stacked one on top of the other, there is a central support via the screw cap 32 and a circumferential support via the carrying and transport ring 22 of the stacked drum. In order to also achieve stack support in the area of the intermediate barrel top, corresponding top elements 46 can be arranged on the surface of the top barrel, as shown in FIG. The attachment elements 46 are each flush with the carrying and transport ring 22. In the embodiment shown in FIG. 8, eight web-shaped attachment elements 46 are provided which are evenly spaced from one another. The attachment elements can of course also have a different shape, for example rectangular or square, and be formed immediately during the blow molding of the barrel or later glued or welded on as separately prefabricated injection molded parts. It is even easier to design the top of the barrel as a whole with a carrying and transport ring, bung and adapter elements using the injection molding process, after which the top of the barrel is welded onto the barrel body blank.
Das erfindungsgemäße Schraubdeckelfaß ist also ausge¬ zeichnet für partikelförmige und flüssige Füllgüter geeignet. Die große Behälteröffnung ist ebenfalls vorteilhaft für den Einsatz eines Rührwerkes (Quirl) z.B. bei zu Entmischung neigenden Füllgütern (z.B. Zinkoxid- Farbe) , die vor einer Füllgutentnähme aufgemischt und homogenisiert werden müssen. Das Faß ist auch für eine Mehrfachverwendung geeignet, da es im Gegensatz zu üb¬ lichen Spundfässern von innen gereinigt werden kann. Und weiterhin wird durch die große Behälteröffnung auch die problemlose Verwendung eines entsprechenden, dünn¬ wandigen Kunststoff-Inliners erstmalig für ein geschlos¬ senes L-Ring-Faß ermöglicht.The screw cap barrel according to the invention is therefore excellently suitable for particulate and liquid contents. The large container opening is also advantageous for the use of an agitator (whisk) e.g. in the case of products that tend to separate (e.g. zinc oxide paint), which have to be mixed and homogenized before the product is removed. The barrel is also suitable for multiple use since, in contrast to conventional sheet piling, it can be cleaned from the inside. Furthermore, the large container opening also enables the problem-free use of a corresponding thin-walled plastic liner for the first time for a closed L-ring barrel.
Um den Einsatzbereich des Schraubdeckel-L-Ring-Fasses schließlich auch für zur Entgasung neigende Füllstoffe zu erweitern, ist - wie in Fig. 8 angedeutet ist - der Schraubdeckel 32 selbst mit einem eine Entgasungseinrich¬ tung 48 aufweisenden Spundstopfen 50 ausgestattet, wodurch eine Überdruckausbildung im Faßinneren verhindert wird.In order to finally expand the area of use of the screw-cover L-ring barrel for fillers that tend to degass, the screw cover 32 itself is equipped with a bung plug 50 having a degassing device 48, as indicated in FIG. 8, which prevents overpressure inside the barrel.
Selbstverständlich kann das erfindungsgemäße Schraubdek- kel-L-Ring-Faß auch mit einem unten umlaufenden Boden- Rollring ausgestattet sein. Of course, the screw cap L-ring barrel according to the invention can also be equipped with a bottom rolling ring running around the bottom.
