Die Erfindung betrifft Kunststoffässer, die als Spundfässer oder Deckelfässer ausgebildet und als Ein- oder Mehrschichtbehälter durch Extrusionsblasformen hergestellt sind.The invention relates to plastic barrels that serve as bung casks or lidded drums formed and as a single or Multilayer containers are produced by extrusion blow molding.

Aus der DE 196 05 890 A1 bekannte Kunststoffässer dieser Art für flüssige und körnige Füllgüter weisen eine dauerantistatische Außenschicht auf, um eine elektrostatische Aufladung der Oberfläche durch Reibung von nebeneinanderstehenden Fässern beim Transport zu verhindern. Auf diese Weise sollen beispielsweise bei Annäherung von elektrisch leitfähigen Gegenständen aus Metall an die Faßoberfläche elektrische Entladungen mit einer Funkenbildung, die zu einer Entzündung von feuergefährlichen Füllgütern der Fässer sowie von explosionsfähigen Gemischen von Gasen und Dämpfen in geschlossenen Räumen führen können, vermieden werden. Durch diese äußere Erdung mittels einer dauerantistatischen Außenschicht der Kunststoffässer können nicht elektrische Ladungen abgeleitet werden, die beim Befüllen und Entleeren der Fässer und beim Rühren von Flüssigkeiten z. B. zu Mischzwecken durch Flüssigkeitsreibung an der Faßinnenfläche und in der Flüssigkeit entstehen.From DE 196 05 890 A1 known Kunststoffässer this kind for liquid and granular products have a Permanently antistatic outer layer on to an electrostatic Charging the surface by friction of to prevent juxtaposed barrels during transport. On This way, for example, when approaching electric conductive metal objects to the barrel surface electrical discharges with a sparking, resulting in a Ignition of flammable contents of barrels and of explosive mixtures of gases and vapors in closed rooms can be avoided. By this external grounding by means of a permanently anti-static Outer layer of plastic barrels can not be electric Charges are discharged when filling and emptying the Barrels and while stirring liquids z. B. for mixing purposes by fluid friction on the barrel inner surface and in the Liquid arise.

Die beschränkte Verwendung des teuren antistatischen Kunststoffmaterials, beispielsweise ein Polyethylen hoher Dichte mit einem Leitrußanteil, für die Ausbildung der elektrisch leitenden Streifen und der dauerantistatischen Außenschicht des ansonsten aus einem preisgünstigen Kunststoffmaterial wie ein Polyethylen hoher Dichte gefertigten Kunststoffasses führt lediglich zu einer geringen Verteuerung der Herstellungskosten. Die elektrische Erdung der Faßoberfläche und des Innenraumes des Kunststoffasses sowie der in diesem zu transportierenden bzw. zu lagernden Flüssigkeiten ermöglicht die Verwendung des Fasses als Gefahrgutbehälter für feuergefährliche Flüssigkeiten und Emulsionen sowie Lösungsmittel, Farben und Lacke mit einem Flammpunkt < 35°C sowie den Einsatz des Fasses in Betriebsräumen, in denen sich eine explosive Atmosphäre durch Gase, Dämpfe oder Nebel bilden kann.The in the non-conductive plastic material of the barrel body designed as a bung or lidded barrel plastic cup embedded strips of an electrically conductive Plastic material whose thickness is the wall thickness of the barrel corresponds, form electrical connections between the Inner surface and the surface of the multilayer barrel, the has a permanent antistatic outer layer, so that both the in the liquid product and on the inner surface of the barrel Fluid friction occurring electric charges as well the electrical charges that are due to friction on the Faßoberfläche can form over the electrically conductive Strip in the barrel body and the permanent antistatic outer layer of the barrel to be derived in the soil. The limited Use of the expensive antistatic plastic material, For example, a high density polyethylene with a Leitrußanteil, for the formation of electrically conductive Strips and the permanent antistatic outer layer of the otherwise from a low-cost plastic material such as a polyethylene high density manufactured Kunststoffasses only leads to a small increase in the cost of production. The electrical grounding of the barrel surface and the interior of the Kunststoffasses and in this to be transported or to stored liquids allows the use of the barrel as Dangerous goods containers for flammable liquids and Emulsions as well as solvents, paints and varnishes with a Flash point <35 ° C and the use of the barrel in Operating rooms in which an explosive atmosphere through Gases, vapors or fog can form.
