Abstract

A barrel of thermoplastic material has at least one connecting portion having an emptying opening and arranged in a trough-like depression in the upper end part of the barrel. In the region of the connecting portion the barrel has at least one inclined surface which extends between the upper end part of the barrel and the side wall of the barrel. The inclined surface is of such a configuration that in a barrel emptying position the emptying opening forms the lowest part of the interior of the barrel to permit at least almost complete emptying of the barrel.

Description

Die Erfindung betrifft ein Faß gemäß dem Oberbegriff des Anspruches 1.The invention relates to a barrel according to the preamble of claim 1.

An ein solches Faß werden bestimmte Anforderungen gestellt, von denen bislang eine ausreichende Widerstandsfähigkeit gegen äußere Krafteinwirkungen, z. B. durch Stöße, Schläge oder Fallbelastungen bei der Ausgestaltung des Fasses im Vordergrund gestanden haben. Ein derartiges Faß ist im allgemeinen mit umlaufenden Ringen versehen, die in einem Abstand vom Ober- bzw. Unterboden angeordnet sind und der Handhabung des Fasses dienen. Weiterhin kann es erforderlich sein, mehrere Fässer übereinander zu stapeln, so daß Ober- und Unterboden eine ausreichende und stabile Standfläche aufweisen müssen. Dabei ist es bekannt, das nach oben vorragende Stutzenteil, welches die Entleerungsöffnung begrenzt, innerhalb einer muldenförmigen Vertiefung des Oberbodens anzuordnen. Dadurch wird gleichzeitig erreicht, daß das vorstehende Stutzenteil gegenüber äußeren Krafteinflüssen weitgehend geschützt ist.Such a barrel is subject to certain requirements, of which so far sufficient resistance to external forces, e.g. B. have stood in the foreground by bumps, blows or falling loads in the design of the barrel. Such a barrel is generally provided with circumferential rings which are arranged at a distance from the top or bottom bottom and are used for handling the barrel. Furthermore, it may be necessary to stack several barrels on top of each other so that the top and bottom floors have to have a sufficient and stable footprint. It is known to arrange the upwardly projecting nozzle part, which delimits the emptying opening, within a trough-shaped depression in the top floor. This also ensures that the protruding neck part is largely protected against external forces.

Im Zuge der Berücksichtigung der Belange der Umwelt muß nunmehr zunehmend auch der Forderung Rechnung getragen werden, ein derartiges Faß restlos entleeren zu können, um zu vermeiden, daß nach der Entleerung im Faß verbleibende Restmengen des Füllgutes unkontrolliert in die Umgebung gelangen und diese belasten.In the course of taking into account the concerns of the environment, the requirement to be able to completely empty such a drum must now be taken into account, in order to prevent residual quantities of the contents remaining in the drum from escaping into the environment in an uncontrolled manner and polluting them.

Die bekannte Anordnung des Stutzenteils innerhalb einer muldenförmigen Vertiefung hat aber den Nachteil, daß auf der Innenseite des Fasses bei der zur Entleerung üblichen Schräglage neben der Mulde Bereiche vorhanden sind, die in dieser Lage tiefer liegen als der auf der Innenwandung liegende tiefste Bereich der Entleerungsöffnung. Es ist daher bekannt, zur Erzielung einer möglichst restlosen Entleerung eines Fasses oder eines ähnlichen Behälters das Stutzenteil nahe der Wand des Behälters anzuordnen, so daß in der üblichen Schräglage des Behälters bei der Entleerung sich auf der Innenseite des letzteren keine Stellen befinden, die tiefer liegen als der auf der Innenseite des Fasses liegende tiefste Bereich der im allgemeinen runden Entleerungsöffnung. Diese Anordnung des Stutzenteils in unmittelbarer Nähe der Faßwandung hat aber den Nachteil, daß das Stutzenteil auch bei der Anordnung in einer muldenförmigen Vertiefung des Oberbodens gegen seitlich von außen auf das Faß einwirkende Kräfte wenig geschützt ist. Dies gilt sowohl für Kräfte, die unmittelbar auf das Stutzenteil einwirken, als auch für auf den Faßrand oder die Faßwandung einwirkende Beanspruchungen, die z. B. bei einem Fall aus größerer Höhe wirksam werden. Die dabei auftretenden Verformungen des Faßrandes oder der Faßwandung wirken sich zwangsläufig auch auf das Stutzenteil und den es tragenden Bereich des Oberbodens aus, wodurch Spannungsspitzen in diesem Bereich entstehen, die zum Auftreten von Rissen und anderen Beschädigungen führen können.The known arrangement of the nozzle part within a trough-shaped recess has the disadvantage that on the inside of the barrel, in the inclined position customary for emptying, there are areas next to the trough which in this position lie deeper than that lying on the inner wall deepest area of the discharge opening. It is therefore known to achieve the most complete emptying of a barrel or a similar container to arrange the nozzle part near the wall of the container, so that in the usual inclined position of the container when emptying there are no places on the inside of the latter that are deeper than the deepest area of the generally round drain opening located on the inside of the barrel. This arrangement of the neck part in the immediate vicinity of the barrel wall has the disadvantage that the neck part is little protected against lateral forces acting on the barrel from the outside even when it is arranged in a trough-shaped recess in the top floor. This applies both to forces that act directly on the nozzle part, as well as to stresses acting on the barrel edge or the barrel wall, which, for. B. take effect in a case from a greater height. The deformations of the barrel edge or the barrel wall that occur inevitably also have an effect on the connecting piece part and the area of the upper floor that supports it, as a result of which stress peaks occur in this area, which can lead to the occurrence of cracks and other damage.

Diese Schwierigkeiten können beispielsweise dadurch verringert werden, daß das Stutzenteil um ein bestimmtes Ausmaß in das Innere des Fasses hineinragt. Dadurch wird erreicht, daß einerseits der nach oben hervorstehende Abschnitt des Stutzenteils kürzer sein kann und andererseits die Tiefe der das Stutzenteil aufnehmenden Mulde verkleinert werden kann und sich damit die Einwirkfläche für äußere Kräfte verringert. Dabei muß der nach innen weisende Abschnitt des Stutzenteil lang genug ausgeführt werden, um einem Verschlußstopfen, der in das mit einem entsprechenden Innengewinde versehenen Stutzenteil eingeschraubt wird, einen ausreichend festen Sitz zu geben. Allerdings stellt jedoch jener Abschnitt des Stutzenteils, der in das Innere des Fasses hineinragt, innenseitig eine Abschirmung der Entleerungsöffnung dar, so daß eine von der axialen Erstreckung dieses Abschnittes abhängige Menge an Füllgut im Faß verbleibt. Eine restlose oder nahezu restlose Entleerung eines Fasses mit einem derartig ausgebildeten Stutzenteil ist nicht möglich.These difficulties can be reduced, for example, in that the neck part protrudes to a certain extent into the interior of the barrel. It is thereby achieved that, on the one hand, the upwardly projecting section of the connecting piece can be shorter and, on the other hand, the depth of the trough receiving the connecting piece can be reduced and thus the area of action for external forces is reduced. The inward-facing section of the neck part must be made long enough to give a sealing plug which is screwed into the neck part provided with a corresponding internal thread, a sufficiently firm fit. However, that portion of the neck part that protrudes into the interior of the barrel is on the inside a shield of the emptying opening, so that one of the axial extent of this portion dependent amount of filling remains in the barrel. A complete or almost complete emptying of a barrel with a nozzle part designed in this way is not possible.

Es ist aus der EP-A-0291695 bekannt, ein Faß mit einem Stutzenteil zu versehen, dessen in das Innere des Fasses hineinragender Abschnitt Durchbrechungen aufweist, die sich bis zur inneren Begrenzungswand der muldenförmigen Vertiefung erstrecken. Auf diese Weise kann das Restfüllgut in Richtung auf die Entleerungsöffnung fließen, ohne daß der nach innen weisende Abschnitt eine Abschirmung der Entleerungsöffnung darstellt. Derartige Stutzenteile müssen jedoch als separate Elemente an den fertigen Behältern angebracht werden, so daß durch die Verbindungsstelle u.U. eine Schwachstelle entsteht, die bei größeren äußeren Krafteinwirkungen zerstört werden könnte. Weiterhin erfordert die Ausbildung des Stutzenteils einen erhöhten Fertigungsaufwand, der sich auf die Wirtschaftlichkeit der im allgemeinen in großer Stückzahl gefertigten Fässer auswirken kann. Außerdem ist bei dieser Ausbildung des Fassses die muldenförmige Vertiefung zur Erzielung einer möglichst restlosen Entleerung so ausgebildet, daß die als Standfläche dienende Oberfläche des Oberbodens verkleinert ist.It is known from EP-A-0291695 to provide a barrel with a neck part, the portion of which protrudes into the interior of the barrel has openings which extend as far as the inner boundary wall of the trough-shaped depression. In this way, the remaining filling material can flow in the direction of the emptying opening without the section pointing inwards being a shield for the emptying opening. Such nozzle parts must, however, be attached to the finished containers as separate elements, so that the connection point may possibly lead to a weak point arises that could be destroyed by greater external forces. Furthermore, the formation of the nozzle part requires an increased manufacturing effort, which can affect the economy of the barrels generally manufactured in large numbers. In addition, in this embodiment of the barrel, the trough-shaped depression is designed to achieve as complete a drainage as possible in such a way that the surface of the upper floor serving as a standing surface is reduced.

Ferner ist aus DE-U-9001802.8 sowie WO 91/12179 veröffentlicht auf 22 August 1991 ein Faß wie beschrieben in dem Oberbegriff des Anspruchs 1 bekannt, das in seiner Entleerungsstellung einen Bereich zwischen dem Stutzen und der Wandung des Fasses aufweist, der tiefer liegt als der tiefste Punkt der innenseitigen Begrenzung der Öffnung im Stutzen. Bei dieser Ausführung sind Taschen vorhanden, in denen beim Entleerungsvorgang Restmengen des Füllgutes verbleiben. Dieses bekannte Faß kann auch innenseitig mit einer Rinne versehen sein, die schrägverlaufend angeordnet ist und der besseren Entleerung dienen soll. Jedoch ändert das Vorhandensein dieser Rinne nichts an der Tatsache, daß der zu beiden Seiten der Rinne befindliche Boden der muldenförmigen Vertiefung in der Normalposition eben ausgebildet ist und horizontal verläuft.Furthermore, from DE-U-9001802.8 and WO 91/12179 published on August 22, 1991, a barrel as described in the preamble of claim 1 is known, which in its emptying position has an area between the neck and the wall of the barrel which is lower than the deepest point of the inside boundary of the opening in the nozzle. In this version there are pockets in which residual quantities of the contents remain during the emptying process. This known barrel can also be provided on the inside with a groove which is arranged at an incline and is intended to serve for better emptying. However, the presence of this channel does not change the fact that the bottom of the trough-shaped depression located on both sides of the channel is flat in the normal position and runs horizontally.

Der Erfindung liegt die Aufgabe zugrunde, ein Faß oder einen Behälter der einleitend beschriebenen Art so auszugestalten, daß es bzw. er zumindest näherungsweise restlos entleert werden kann. Dabei soll die Herstellung unkompliziert und die Handhabung des Behälters bei der Entleerung einfach sein. Da derartige Behälter meistens als Faß ausgebildet sind, wird im folgenden überwiegend von einem Faß gesprochen, ohne daß damit eine Einschränkung verbunden sein soll.The invention has for its object to design a barrel or a container of the type described in the introduction so that it or he can be emptied at least approximately completely. The production should be uncomplicated and the handling of the container should be simple when emptying. Since containers of this type are mostly designed as a barrel, the following is mainly referred to as a barrel, without any restriction being connected therewith.

Als Lösung schlägt die Erfindung ein faß gemäß dem Anspruch 1 vor. Der Verlauf der, die muldenförmige Vertiefung des Oberbodens zwischen Stutzenteil und Ring schneidenden Schrägfläche entspricht dabei, je nach Ausbildung des Faßabschnittes, näherungsweise einer schiefen Schnittfläche bei einem Zylinder bzw. Kegel. Zweckmäßig ist dabei die Schrägfläche symmetrisch zu der Entleerungsöffnung auszubilden bzw. anzuordnen.As a solution, the invention proposes a barrel according to claim 1. The course of the sloping surface that cuts the trough-shaped depression of the top floor between the connecting piece part and the ring corresponds, depending on the design of the barrel section, approximately to an oblique cutting surface in the case of a cylinder or cone. The inclined surface is expediently to be designed or arranged symmetrically to the emptying opening.

Bei einer Ausführungsform ist die Schrägfläche eben ausgebildet. Eine derartige Ausgestaltung erfordert jedoch eine genaue Einhaltung der Winkellage des Fasses bei der Entleerung sowohl bezüglich der Kippachse als auch bezüglich einer Verdrehnung, z.B. um die axialen Hauptachse des Fasses. Um zu vermeiden, daß bei geringfügiger Verdrehung des Fasses das Füllgut sich im Faß neben der Entleerungsöffnung sammelt, ist es zweckmäßig, die Schrägfläche in zwei Teilflächen zu unterteilen, die bezüglich einer radial zum Faßquerschnitt verlaufenden Trennlinie geringfügig verschwenkt angeordnet sind, so daß sie auf der Innenseite des Fasses einen Winkel einschließen, der etwas kleiner als 180° ist. Damit ist gewährleistet, daß auch bei geringfügiger Verdrehung eine annähernd restlose Entleerung möglich ist, da sich der tiefste Bereich der Entleerungsöffnung in der durch die beiden Teilflächen gebildeten Rinne befindet.In one embodiment, the inclined surface is flat. Such a configuration, however, requires exact compliance with the angular position of the barrel when emptying both with respect to the tilting axis and with respect to twisting, e.g. around the main axial axis of the barrel. In order to prevent the contents from collecting in the barrel next to the emptying opening when the barrel is slightly rotated, it is expedient to divide the inclined surface into two partial surfaces, which are arranged slightly pivoted with respect to a dividing line running radially to the barrel cross section, so that they are on the Include an angle on the inside of the barrel that is slightly less than 180 °. This ensures that an almost complete emptying is possible even with slight twisting, since the deepest area of the emptying opening is in the channel formed by the two partial surfaces.

Vorteilhaft kann es dabei auch sein, die Schrägfläche in zwei Teilflächen zu unterteilen, die bezüglich einer Sehne, welche durch den tiefsten Bereich der Entleerungsöffnung verläuft, geringfügig verschwenkt angeordnet sind, so daß sie auf der Innenseite des Fasses einen Winkel einschließen, der etwas kleiner als 180° ist. Damit kann das Faß auch dann nahezu restlos entleert werden, wenn die Kipplage von der optimalen Entleerungsposition geringfügig abweicht.It can also be advantageous to subdivide the inclined surface into two partial surfaces, which are arranged slightly pivoted with respect to a chord which runs through the deepest region of the emptying opening, so that they enclose an angle on the inside of the barrel which is somewhat smaller than Is 180 °. So that the barrel can almost be completely emptied if the tipping position deviates slightly from the optimal emptying position.

Demzufolge ist es natürlich auch möglich, die Schrägfläche derart zu unterteilen, daß die beiden Teilflächen, die bezüglich einer annähernd radialen Trennlinie geringfügig verschwenkt angeordnet sind, zusätzlich jeweils in zwei Teilflächen zu unterteilen, die bezüglich der oben genannten Sehne geringfügig verschwenkt angeordnet sind. Die Schrägfläche setzt sich demnach aus vier Teilflächen zusammen, die eine trichterartige Pyramide bilden, deren tiefster Punkt dem tiefsten Bereich der Entleerungsöffnung entspricht. Damit ist es möglich, daß auch bei geringfügigen Verdrehungen oder Verschwenkungen des Fasses aus seiner optimalen Entleerungsposition letzteres zumindest annähernd restlos entleert werden kann.Accordingly, it is of course also possible to subdivide the inclined surface such that the two partial surfaces, which are arranged slightly pivoted with respect to an approximately radial dividing line, are each additionally subdivided into two partial surfaces, which are arranged slightly pivoted with respect to the above-mentioned chord. The inclined surface is therefore composed of four sub-areas that form a funnel-like pyramid, the lowest point of which corresponds to the lowest area of the emptying opening. It is thus possible that the barrel can be at least almost completely emptied from its optimal emptying position even if the barrel is rotated or pivoted slightly.

Jedenfalls kann das Faß in eine optimale Entleerungsposition gebracht werden, in welcher es ohne zusätzliche Maßnahmen entleert werden kann, abgesehen natürlich von jenen Bestandteilen, die an der Faßwandung haften bleiben.In any case, the barrel can be brought into an optimal emptying position in which it can be emptied without additional measures, apart from, of course, those components which adhere to the barrel wall.

Weiterhin kann es zweckmäßig sein, daß die Schrägfläche mit einer radial zur Entleerungsöffnung verlaufenden rinnenartigen Vertiefung versehen ist, die in die Entleerungsöffnung mündet, wodurch ebenfalls eine Vereinfachung des Entleerungsvorganges bewirkt werden kann.Furthermore, it may be expedient that the inclined surface is provided with a groove-like depression which extends radially to the emptying opening and which opens into the emptying opening, which can likewise simplify the emptying process.

Ebenfalls ist es zweckmäßig, die Schrägfläche so auszubilden, daß letztere ohne Belassung eines Absatzes unmittelbar in die Seitenwandung und den Oberboden des Fasses übergeht, wodurch Mulden oder Taschen vermieden werden, innerhalb welcher sich andernfalls Füllgut sammeln kann.It is also expedient to design the inclined surface so that the latter merges directly into the side wall and the top of the barrel without leaving a shoulder, thereby avoiding hollows or pockets within which contents can otherwise collect.

Natürlich ist es auch möglich, die Schrägfläche oder auch die oben beschriebenen Teilflächen innenseitig leicht konvex gewölbt auszubilden wobei die Scheitellinie bzw. Scheitellinien der Fläche(n) den oben genannten Trennlinien entspricht bzw. entsprechen.Of course, it is also possible to make the inclined surface or also the partial surfaces described above slightly convex on the inside, the apex line or apex lines the area (s) corresponds to the above-mentioned dividing lines.

Im allgemeinen wird die Schrägfläche so ausgebildet sein, daß deren auf der Außenwandung des Fasses liegende Scheitelpunkt nahe dem zur Handhabung dienenden Ring angeordnet ist und sich die Fläche neben der Entleerungsöffnung bis zur entsprechenden, ggf. konisch verlaufenden Seitenwandung des bei aufrecht stehendem Faß oberen Faßabschnittes erstreckt. Zur Erzielung eines günstigen Neigungswinkels kann es ggf. erforderlich sein, den zur Handhabung dienenden Ring in einem größeren Abstand vom Oberboden anzuordnen, als es im allgemeinen üblich ist. Dies stellt jedoch keine Beeinflussung der Handhabung dar. Weiterhin kann bei zwei gegenüberliegenden Öffnungen jeder Öffnung jeweils eine derartige Schrägfläche zugeordnet sein.In general, the inclined surface will be designed so that its apex lying on the outer wall of the barrel is arranged near the ring used for handling and the surface extends next to the emptying opening up to the corresponding, if necessary conical side wall of the upper barrel section when the barrel is upright . In order to achieve a favorable angle of inclination, it may be necessary to arrange the ring used for handling at a greater distance from the top floor than is generally the case. However, this does not affect the handling. Furthermore, with two opposing openings, each such opening can be assigned to each opening.

Durch die Ausbildung des Fasses gemäß der Erfindung ist es möglich, daß das Faß ohne weiteres restlos entleert werden kann, wobei gleichzeitig zum Schutz vor Beschädigung des Stutzenteils dieses auf dem Oberboden in einem Abstand von der Seitenwandung des Fasses angeordnet werden kann.Due to the design of the barrel according to the invention, it is possible that the barrel can be emptied without any problems whatsoever, and at the same time it can be arranged on the top floor at a distance from the side wall of the barrel to protect it from damage.

Die Anordnung einer Schrägfläche im Bereich des Faßabschnitts zwischen Oberboden und Handhabungsring hat aber auch zur Folge, daß einerseits die Standfläche des Oberbodens verringert wird und andererseits der gegenüber der Faßkontur vorstehende Abschnitt des Stutzenteils wenig geschützt ist.The arrangement of an inclined surface in the region of the barrel section between the top shelf and the handling ring also has the consequence that, on the one hand, the footprint of the top shelf is reduced and, on the other hand, the section of the connecting piece protruding relative to the barrel contour is little protected.

Die Erfindung sieht daher weiterhin die Möglichkeit vor, wenigstens einen Ergänzungskörper vorzusehen, der so ausgestaltet und auf der Schrägfläche angeordnet ist, daß er einerseits die durch die Schrägfläche bewirkte Verkleinerung der im wesentlichen horizontalen Standfläche zumindest näherungsweise ausgleicht. Andererseits kann es in vorteilhafter Weise auch so ausgebildet sein, daß es gleichzeitig das Stutzenteil weitgehend vor äußeren Krafteinflüssen schützt.The invention therefore further provides the possibility of providing at least one supplementary body which is designed and arranged on the inclined surface in such a way that it at least approximately compensates for the reduction in the essentially horizontal standing surface caused by the inclined surface. On the other hand, it can advantageously also be designed in such a way that it largely protects the connecting piece from external forces at the same time.

Der Ergänzungskörper ist dabei gemäß der Erfindung vorteilhaft so ausgebildet, daS seine untere Fläche der oberen Kontur der Schrägfläche entspricht, während die obere Fläche des Ergänzungskörpers in seiner wirksamen Lage im wesentlichen horizontal und fluchtend mit der als Standfläche dienenden Fläche des Oberbodens verläuft. Es ist dabei möglich, daß der Ergänzungskörper mehrere vertikale Rippen oder eine vertikal angeordnete Gitterstruktur aufweist, deren obere Begrenzung mit der als Standfläche dienenden horizontalen Fläche des Oberbodens fluchtet.The supplementary body is advantageously designed in accordance with the invention in such a way that its lower surface corresponds to the upper contour of the inclined surface, while the upper surface of the supplementary body in its effective position runs essentially horizontally and in alignment with the surface of the upper floor serving as a standing surface. It is possible for the supplementary body to have a plurality of vertical ribs or a vertically arranged lattice structure, the upper boundary of which is aligned with the horizontal surface of the upper floor serving as a standing surface.

Der Ergänzungskörper kann dabei z.B. mittels Spritzgießen oder Blasformen oder auf andere Weise hergestellt und hohl oder massiv ausgebildet sein. Damit das Ergänzungsteil die erforderlichen Belastungen aufnehmen kann, ist es zweckmäßig, es mit dem Faß zu verkleben oder zu verschweißen. Da im allgemeinen ein derartiges Faß mittels Blasformen hergestellt wird, bei welchem ein im wesentlichen schlauchförmiger Vorformling unter inneren Überdruck in einer unterteilten, ein Formnest begrenzenden Blasform aufgeweitet wird, kann es zweckmäßig sein, den Ergänzungskörper vor dem Aufweitprozeß in die Blasform einzulegen. Dadurch kann eine besonders gute Anpassung der unteren Seite des Ergänzungskörpers an die äußere Kontur der Schrägfläche bewirkt werden. Wenn Ergänzungskörper und Faß zudem aus Kunststoffen bestehen, die miteinander verschweißbar sind, kann auf diese Weise eine besonders haltbare Verbindung der beiden Teile bewirkt werden.The supplementary body can e.g. be produced by injection molding or blow molding or in some other way and be hollow or solid. So that the supplementary part can absorb the necessary loads, it is advisable to glue or weld it to the barrel. Since such a barrel is generally produced by means of blow molding, in which an essentially tubular preform is expanded under internal pressure in a divided blow mold which delimits a mold cavity, it may be expedient to insert the supplementary body into the blow mold before the expansion process. This allows a particularly good adaptation of the lower side of the supplementary body to the outer contour of the inclined surface. If the supplementary body and barrel also consist of plastics that can be welded together, a particularly durable connection of the two parts can be brought about in this way.

Das in der Zeichnung dargestellte Faß 1 weist einen Faßkörper 10, einen Oberboden 3 und einen nicht dargestellten Unterboden auf. In einem Abstand vom Oberboden 3 ist ein umlaufender Ring 9 angeordnet, an welchem Handhabungsmittel angreifen können. Der Oberboden 3 ist an zwei gegenüberliegenden Seiten mit jeweils einer muldenförmigen Vertiefung 5 versehen, innerhalb welcher ein Stutzenteil 7 angeordnet ist, das eine Entleerungsöffnung 6 aufweist. Das in der Zeichnung dargestellte Faß weist zwei derartige Anordnungen auf, deren Entleerungsöffnungen unterschiedliche Durchmesser haben. Selbstverständlich können die stutzenteile auch gleiche Abmessungen aufweisen. Es kann auch nur einseitig eine derartige Anordnung vorgesehen sein.The barrel 1 shown in the drawing has a barrel body 10, an upper floor 3 and a lower floor, not shown. A circumferential ring 9 is arranged at a distance from the upper floor 3, on which handling means can act. The upper floor 3 is provided on two opposite sides, each with a trough-shaped depression 5, within which a nozzle part 7 is arranged, which has an emptying opening 6. The barrel shown in the drawing has two such arrangements, the emptying openings have different diameters. Of course, the nozzle parts can also have the same dimensions. Such an arrangement can also be provided only on one side.

Im Bereich des Stutzenteils 7 weist der konische Faßabschnitt 4 zwischen Oberboden 3 und umlaufendem Handhabungsring 9 eine Schrägfläche 11 auf, die sich näherungsweise bis zu dem Ring 9 erstreckt. Wie in Fig. 1 gezeigt, sind die Neigung und das Ausmaß dieser Fläche 11 so gewählt, daß letztere an den Bereich 16 der Entleerungsöffnung 6 angrenzt, welcher in der Entleerungslage den tiefsten Bereich der Entleerungsöffnung 6 auf der Innenwandung des Fasses darstellt. Die Neigung der Schrägfläche 11 hängt unter anderem ab von dem Abstand der der Außenwandung des Fasses zugewandten Seite 15 des Stutzenteils 7 von der Außenwandung und dem Abstand des umlaufenden Handhabungsrings 9 vom Oberboden 3. Die Neigung kann beispielsweise ca. 45° betragen. Die Bereiche 13 und 14 der Schrägfläche 11, die neben der muldenförmigen Vertiefung 5 verlaufen, erstrecken sich bis zur Begrenzungswandung des oberen Faßabschnitts 4. Bei einem üblichen, wie in der Zeichnung dargestelltem Faß verläuft der Faßabschnitt 4 konisch, da dies für den Eingriff des Handhabungsmittels mit dem Handhabungsring günstig ist. Es ist aber möglich, daß dieser Faßabschnitt annähernd vertikale Seitenwände aufweist und somit eine im wesentlichen zylindrische Form hat.In the area of the nozzle part 7, the conical barrel section 4 between the top 3 and the circumferential handling ring 9 has an inclined surface 11 which extends approximately up to the ring 9. As shown in Fig. 1, the inclination and the extent of this surface 11 are chosen so that the latter adjoins the area 16 of the emptying opening 6, which in the emptying position represents the deepest area of the emptying opening 6 on the inner wall of the barrel. The inclination of the inclined surface 11 depends, among other things, on the distance between the side 15 of the nozzle part facing the outer wall of the barrel 7 from the outer wall and the distance of the circumferential handling ring 9 from the top floor 3. The inclination can be approximately 45 °, for example. The areas 13 and 14 of the inclined surface 11, which run next to the trough-shaped recess 5, extend to the boundary wall of the upper barrel section 4. In a conventional barrel, as shown in the drawing, the barrel section 4 is conical, since this is for the engagement of the handling means is cheap with the handling ring. But it is possible that this barrel section has approximately vertical side walls and thus has a substantially cylindrical shape.

Die in der Beschreibung aufgeführten geometrischen Definitionen sollen nur zur besseren Beschreibung der geometrischen Formgebung dienen. Ein derartiges Faß entspricht ohnehin nicht exakt den genannten geometrischen Formen, da es während der Abkühlung nach dem Herstellungsprozeß z.B. mittels Blasformen, Verformungen erfährt, die nicht vorhersehbar und nicht streng geometrisch sind.The geometric definitions listed in the description are only intended to provide a better description of the geometric shape. In any case, such a barrel does not exactly correspond to the geometric shapes mentioned, since during cooling after the manufacturing process it e.g. through blow molding, experiences deformations that are not predictable and not strictly geometric.

Fig. 5 a-c stellen den Entleerungsvorgang bei unterschiedlichen Neigungspositionen des Fasses dar. Es ist zu erkennen, daß durch die Anordnung der Schrägfläche 11 im Faßbereich 4 eine optimale Entleerungsposition (Fig. 5b) gefunden werden kann, bei welcher keine Stelle im Inneren des Fasses vorhanden ist, die tiefer liegt als der auf der Innenwandung des Fasses liegende tiefste Bereich 16 der Entleerungsöffnung 6.Fig. 5 ac represent the emptying process at different inclination positions of the barrel. It can be seen that an optimal emptying position (Fig. 5b) can be found by the arrangement of the inclined surface 11 in the barrel area 4, in which there is no place inside the barrel which is lower than the deepest region 16 of the emptying opening 6 lying on the inner wall of the barrel.

In Fig. 4 wird deutlich, daß durch eine geringfügig verschwenkte Anordnung der Teilflächen 13 und 14 um eine annähernd radial verlaufende Trennlinie 17 (Fig. 7) nach innen eine nahezu völlige Entleerung des Fasses auch dann möglich sein wird, wenn das Faß so verdreht ist, daS die Trennlinie 17 in der Kipplage nicht mehr durch den tiefsten Punkt der Innenseite der Faßwandung verläuft.In Fig. 4 it is clear that a slightly pivoted arrangement of the sub-areas 13 and 14 around an approximately radially extending dividing line 17 (Fig. 7) inwardly an almost complete emptying of the barrel will be possible even if the barrel is so twisted that the dividing line 17 no longer runs through the lowest point on the inside of the barrel wall in the tilted position.

In Fig. 6 ist zusätzlich eine radial verlaufende, rinnenartige Vertiefung 31 der Schrägfläche 11 dargestellt, die von der Wandung des Fasses bis zur Entleerungsöffnung 6 verläuft. Dadurch kann eine Vereinfachung des Entleerungsvorganges bewirkt werden.6 also shows a radially running, groove-like depression 31 of the inclined surface 11, which extends from the wall of the barrel to the emptying opening 6. This can simplify the emptying process.

Es ist insbesondere aus der Fig. 5b ersichtlich, daß eine Unterteilung der Teilflächen 13, 14 in zwei weiter Teilflächen, die bezüglich der Sehne 18 (Fig. 7), die zumindest näherungsweise durch den der Außenwandung am nächsten liegendem Punkt verläuft, geringfügig verschwenkt angeordnet sind, eine weitere Vereinfachung des Entleerungsvorganges erreicht werden kann. Die Entleerungsöffnung stellt nämlich auch dann mit zumindest einem Teilabschnitts ihres auf der Innenseite der Faßwandung liegenden Umfanges den tiefsten Bereich in der Entleerungslage dar, wenn das Faß von der optimalen Entleerungsposition (Fig. 5b) bezüglich der Kipplage geringfügig abweicht. Es ist natürlich auch möglich, die Schrägfläche 11 lediglich bezüglich der Sehne 18 zu unterteilen.It can be seen in particular from FIG. 5b that the sub-areas 13, 14 are subdivided into two further sub-areas, which are slightly pivoted with respect to the chord 18 (FIG. 7), which at least approximately runs through the point closest to the outer wall are a further simplification of the emptying process can be achieved. With at least a portion of its circumference lying on the inside of the barrel wall, the emptying opening represents the deepest area in the emptying position even if the barrel deviates slightly from the optimal emptying position (FIG. 5b) with respect to the tilting position. It is of course also possible to subdivide the inclined surface 11 only with respect to the chord 18.

Das maximal zulässige Ausmaß der Abweichungen von der optimalen Entleerungsposition sowohl bezüglich der Kipplage als auch bezüglich einer Verdrehung ist jedenfalls dann erreicht, wenn eine der Teilflächen eine waagerechte Lage einnimmt und bei einer weiteren Abweichung die Entleerungsöffnung mit keinem Teilabschnitt ihres auf der Innenwandung liegenden Umfanges den tiefsten Bereich des Fasses bildet.The maximum permissible extent of the deviations from the optimal emptying position both with regard to the tilting position and with respect to rotation is reached in any case when one of the partial surfaces assumes a horizontal position and, in the event of a further deviation, the emptying opening does not have the deepest part with its circumference lying on the inner wall Area of the barrel forms.

Zum Schutz des seitlich freiliegenden stutzenteils 7 sind Ergänzungskörper 21, 22 vorgesehen, die auf der Schrägfläche 11 durch Kleben oder Schweißen befestigt werden. Die der Schrägfläche 11 zugekehrten unteren Seiten 23, 24 der Ergänzungskörper 21, 22 sind so ausgebildet, daß sie im wesentlichen der Kontur der Teilflächen 13, 14 entsprechen. Die Höhe der Ergänzungskörper 21, 22 und die Neigung der unteren Seiten 23, 24 sind so bemessen, daS die Oberseiten 25, 26 der Ergänzungskörper in deren mit dem Faß verbundenen Lage bei aufrecht stehendem Faß horizontal verlaufen und die ebenfalls horizontale Standfläche des Oberbodens 3 ergänzen. In Fig. 8 ist ein anderer Ergänzungskörper 29 dargestellt, der einstückig ausgebildet ist.To protect the laterally exposed connecting piece 7, supplementary bodies 21, 22 are provided which are fastened to the inclined surface 11 by gluing or welding. The lower sides 23, 24 of the supplementary bodies 21, 22 facing the inclined surface 11 are designed such that they essentially correspond to the contour of the partial surfaces 13, 14. The height of the supplementary bodies 21, 22 and the inclination of the lower sides 23, 24 are dimensioned such that the upper sides 25, 26 of the supplementary bodies in their position connected to the barrel upright barrel run horizontally and complete the horizontal base of the top 3. Another supplementary body 29 is shown in FIG. 8, which is formed in one piece.

Die Erfindung ist anwendbar unabhängig davon, wie das Faß hergestellt wird. Es ist möglich, das Faß durch Extrusionsblasformen herzustellen, wobei die Entleerungsöffnung(en) in der Trennebene der Blasform und somit in der Schweißnaht 32 des Oberbodens liegen kann bzw. können, durch die der Vorformling, aus welchem das Faß geblasen worden ist, mittels Schweißen verschlossen wurde. Es ist aber auch möglich zumindest eine Öffnung außerhalb der Schweißnaht dieser gegenüber z. B. um 90° versetzt anzuordnen.The invention is applicable regardless of how the barrel is made. It is possible to manufacture the barrel by extrusion blow molding, the emptying opening (s) being in the parting plane of the blow mold and thus in the weld seam 32 of the top floor, through which the preform from which the barrel has been blown can be welded was locked. However, it is also possible to have at least one opening outside of the weld seam opposite z. B. offset by 90 °.

Im übrigen wird zur Verdeutlichung der erfindungsgemäßen Ausgestaltung des Oberbodens des Fasses auch auf die beigefügte Zeichnung verwiesen.Otherwise, reference is also made to the attached drawing to clarify the design of the top of the barrel according to the invention.
