Nach bevorzugter Ausführungsform der Erfindung weist der Faßdeckel eine umlaufende Sammelrinne auf, die, zum Faßinnenraum konkav verlaufend, das Niveau des Faßdeckels nach oben hin überragt, wobei die Sammelrinne die Spundausbildungen aufweist. Dabei ist die Anordnung zweckmäßigerweise so getroffen, daß die Sammelrinne, bei um 180° gedrehtem Faß, im Bereich der Befüll- und Entleerungsspundausbildung ihren tiefsten Punkt aufweist. Der Faßdeckel fällt zweckmäßigerweise, bei um 180° gedrehtem Faß, zur Sammelrinne hin, als Ablaufschräge ab. Im Rahmen der Erfindung liegt es, den Faßmantel nach außen hin mit konvexen Faßreifenausformungen zu versehen, so daß das Faß auf diesen sowie auf den L-Fuß-Flanschen rollbar ist.To achieve this object, the invention provides a barrel formed by blow molding from thermoplastic
  • Barrel jacket,
  • molded barrel bottom,
  • molded barrel lid,
  • Ventilation bung training as well
  • Filling and emptying bung training,
the bung formations are arranged in the barrel cover and the following features are realized:
  • a) The bung formation protrudes above the level of the drum cover,
  • b) there is a depression in the barrel bottom below the filling and emptying bung training,
  • c) in the area of the barrel cover, a handling ring with an L-shaped cross section is connected to the barrel jacket,
  • d) in the area of the barrel bottom, a handling ring with an L-shaped cross section is connected to the barrel jacket,
wherein the handling rings have an L-foot flange, which is arranged in the region of the barrel casing and projects freely outwards, and wherein the handling rings have an L-web collar that levels the bung formation upwards and the recess in the barrel bottom downwards surrounds or towers. According to a preferred embodiment of the invention, the drum cover has a circumferential collecting trough which, concave to the interior of the drum, projects above the level of the drum cover, the collecting trough having the sheet piling. The arrangement is expediently such that the collecting trough has its lowest point in the area of the filling and emptying bung formation when the barrel is rotated through 180 °. The barrel lid expediently falls off as a run-off slope when the barrel is turned through 180 ° toward the collecting trough. It is within the scope of the invention to provide the barrel jacket with convex barrel tire formations on the outside, so that the barrel can be rolled on it and on the L-foot flanges.

Die Erfindung geht von der Erkenntnis aus, daß die Fertigung eines Fasses des eingangs beschriebenen grundsätzlichen Aufbaus durch Blasformgebung beachtlich vereinfacht werden kann, wenn die Handlingringe nicht im Wege der Blasformgebung angeformt, sondern als selbständige Bauteile ausgeführt und nachträglich mit dem blasgeformten Faßkörper verbunden sind. Die Verbindung kann formschlüssig durch entsprechende Formschlußelemente oder auch stoffschlüssig durch Verschweißen erfolgen. Bei dieser Art und Weise der Fertigung kann der Faßkörper ohne Schwierigkeit so ausgeformt werden, daß eine sehr weitgehende Vollentleerung erfolgt.The invention is based on the knowledge that the manufacture of a barrel of the type described above basic structure can be considerably simplified by blow molding if the handling rings are not molded on by blow molding, but are designed as independent components and are subsequently connected to the blow molded barrel body. The connection can be made in a form-fitting manner by means of corresponding form-fitting elements or also materially by welding. With this type of production, the barrel body can be shaped without difficulty so that a very extensive full emptying takes place.

Im folgenden wird die Erfindung anhand einer lediglich ein Ausführungsbeispiel darstellenden Zeichnung ausführlicher erläutert. Die einzige Figur zeigt einen Vertikalschnitt durch ein erfindungsgemäßes Faß.In the following, the invention will be explained in more detail with reference to a drawing showing only one exemplary embodiment. The single figure shows a vertical section through a barrel according to the invention.

Das in der Zeichnung dargestellte Faß 1 besteht aus thermoplastischem Kunststoff und ist durch Blasformgebung geformt. Zum grundsätzlichen Aufbau gehören der Faßmantel 2, ein angeformter Faßboden 3, ein angeformter Faßdeckel 4, eine Lüftungsspundausbildung 5 sowie eine Befüll- und Entleerungsspundausbildung 6. Die Spundausbildungen 5, 6 sind im Faßdeckel angeordnet.The barrel 1 shown in the drawing consists of thermoplastic material and is shaped by blow molding. The basic structure includes the barrel casing 2, a molded barrel bottom 3, a molded barrel cover 4, a ventilation bung formation 5 and a filling and emptying bung formation 6. The bung formation 5, 6 are arranged in the barrel cover.

Man entnimmt aus der Figur daß die Spundausbildungen 5, 6 das Niveau des Faßdeckels 4 nach oben hin überragen. Unterhalb der Befüll- und Entleerungsspundausbildung 6 befindet sich im Faßboden 2 eine Vertiefung 7.It can be seen from the figure that the bung 5, 6 protrude the level of the barrel cover 4 upwards. Below the filling and emptying bung 6 there is a recess 7 in the barrel bottom 2.

Im Bereich des Faßdeckels 4 ist an den Faßmantel 2 ein im Querschnitt L-förmiger Handlingring 8 angeschlossen. Umgekehrt ist im Bereich des Faßbodens 3 an den Faßmantel 2 ein im Querschnitt L-förmiger Handlingring 8 angeschlossen. Die Anordnung ist so getroffen, daß die Handlingringe 8 einen L-Fuß-Flansch 9 aufweisen, der im Bereich des Faßmantels 2 angeordnet ist und nach außen frei vorsteht. Die Anordnung ist fernerhin so getroffen, daß die Handlingringe 8 einen L-Steg-Kragen 10 aufweisen, der die Spundausbildungen 5, 6 nach oben hin und die Vertiefung 7 im Faßboden 3 nach unten hin niveaugleich umgibt oder überragt.In the region of the drum cover 4, a handling ring 8 with an L-shaped cross section is connected to the drum casing 2. Conversely, a handling ring 8 with an L-shaped cross section is connected to the barrel jacket 2 in the region of the barrel bottom 3. The arrangement is such that the handling rings 8 have an L-foot flange 9 which is arranged in the region of the barrel jacket 2 and projects freely outwards. The arrangement is also such that the handling rings 8 have an L-web collar 10, which surrounds or surmounts the sheet formations 5, 6 upwards and the recess 7 in the barrel base 3 downwards at the same level.

Im Ausführungsbeispiel und nach bevorzugter Ausführungsform der Erfindung besitzt der Faßdeckel 4 eine umlaufende Sammelrinne 11, die zum Faßinnenraum konkav verläuft und das Niveau des Faßdeckels 4 nach oben hin überragt. Die Sammelrinne 11 weist die Spundausbildungen 5, 6 auf.In the exemplary embodiment and according to a preferred embodiment of the invention, the drum cover 4 has a circumferential collecting channel 11 which is concave to the interior of the drum and projects above the level of the drum cover 4. The collecting trough 11 has the sheet formations 5, 6.

Im einzelnen ist die Anordnung so getroffen, daß die Sammelrinne 11, bei um 180° gedrehtem Faß 1, im Bereich der Befüll- und Entleerungsspundausbildung 6 ihren tiefsten Punkt aufweist, was in der Zeichnung aus Maßstabsgründen nicht sehr deutlich erkennbar ist. Die Ausbildung ist ferner so getroffen, daß der Faßdeckel 4 bei um 180° gedrehtem Faß 1 zur Sammelrinne 11 hin als Ablaufschräge abfällt.In detail, the arrangement is such that the collecting trough 11, with barrel 1 rotated through 180 °, has its lowest point in the area of the filling and emptying bung 6, which is not very clearly visible in the drawing for reasons of scale. The training is also such that the barrel cover 4 drops when the barrel 1 is rotated through 180 ° toward the collecting trough 11 as a run-off slope.

Am Faßmantel 2 erkennt man nach außen konvexe Faßreifen 12, die gleichsam als Sicke ausgeführt sind. Hier ist die Anordnung so getroffen, daß das Faß 1 auf den L-Fuß-Flanschen 9 und auf diesen Faßreifen 12 rollbar ist.On the barrel jacket 2 you can see convex barrel tires 12, which are designed as a bead. Here the arrangement is such that the barrel 1 can be rolled on the L-foot flanges 9 and on these barrel tires 12.
