Description

Adapter und Verfahren zur Herstellung eines Behälters unter Verwendung des Adapters sowie Behälter mit dem Adapter  Adapter and method of manufacturing a container using the adapter and container with the adapter
Die Erfindung betrifft einen Adapter zur Befestigung eines in einen Behälter aus thermoplastischem Kunststoff einzusetzenden Anschlusselements. Die Erfindung betrifft weiterhin ein Ver fahren zur Herstellung eines Behälters mit einem solchen Adap ter sowie einen Behälter mit dem Adapter. The invention relates to an adapter for fastening a connection element to be inserted into a container made of thermoplastic material. The invention further relates to a Ver drive for producing a container with such Adap ter and a container with the adapter.
Die Erfindung betrifft insbesondere einen Adapter zur Befesti gung eines in einen Kraftstoffbehälter aus thermoplastischem Kunststoff einzusetzenden Anschlusselements. The invention particularly relates to an adapter for fastening movement of a to be used in a fuel tank made of thermoplastic plastic connection element.
Als Anschlusselemente im Sinne der vorliegenden Erfindung kom men beispielsweise Ventile, Ventilgehäuse, Anschlussstutzen, Nippel oder dergleichen in Betracht. As connecting elements in the context of the present invention, for example, men valves, valve body, connecting pieces, nipples or the like into consideration.
Insbesondere an Kraftstoffbehälter werden erhöhte Anforderun gen an deren Beständigkeit und Undurchlässigkeit für Kohlen wasserstoffe gestellt. Moderne Kraftstoffbehälter umfassen da her in der Regel ein Wandaufbau aus einem Laminat an thermo plastischen Kunststoffen mit einer oder mehreren für Kohlen wasserstoffe schwer permeablen Barriereschichten, die eine di rekte Diffusion von Kohlenwasserstoffen durch die Wand des Kraftstoffbehälters verhindern. In dieser Hinsicht problema tisch sind jedoch Anschlussöffnungen in dem Kraftstoffbehäl ter, die einen Dichtsitz für Stutzen, Ventile oder dergleichen bilden. Anschlussöffnungen in der Wand des Kraftstoffbehälters stellen zwangsläufig Unterbrechungen des Barrieresystems dar. Es sind verschiedene Möglichkeiten bekannt, Anschlusselemente in im Kraftstoffbehälter vorgesehene Anschlussöffnungen spiel frei und im Wesentlichen für den Durchtritt von Kohlenwasser stoffen abgedichtet einzusetzen. Beispielsweise besteht die Möglichkeit, die Anschlusselemente mit der Behälterwand zu verschweißen. Häufig bestehen Anschlusselemente wie beispiels weise Anschlussstutzen oder Ventilgehäuse aus einem thermo plastischen Kunststoff, der nicht im Sinne einer Verschweiß barkeit mit der Behälterwand kompatibel ist. Dann kommt ein Verschweißen mit der Behälterwand nicht ohne weiteres in Be tracht, insbesondere für Ventile und Anschlussstutzen, die aus Materialien wie POM ( Polyoxymethylen) oder ABS (Acrylnitril- Butadien-Styrol-Copolymer) bestehen. Es ist bekannt, dass Po lyethylen und Polyoxymethylen nicht miteinander verschweißbar sind. Deswegen ist es bekannt, aus POM bestehende Ventile oder Nippel mit einem aus PE oder HDPE angespritzten Schaft zu ver sehen, der im Bereich der Anschlussöffnung des Behälters mit diesem verschweißt wird, beispielsweise im Heizelement- Schweißverfahren . In particular, fuel tanks are elevated requirements for their durability and impermeability to hydrocarbons. As a result, modern fuel tanks generally comprise a wall structure made of a laminate of thermoplastics with one or more barrier layers which are difficult to penetrate for hydrocarbons and which prevent a direct diffusion of hydrocarbons through the wall of the fuel tank. In this regard, problematic table but connection openings in the Kraftstoffbehäl ter, a sealing seat for nozzles, valves or the like form. Connection openings in the wall of the fuel tank are inevitably interruptions of the barrier system. There are various ways known to use connection elements in the fuel tank provided in connection openings free play and sealed material substantially for the passage of hydrocarbons. For example, it is possible to weld the connection elements with the container wall. Often there are connection elements such as example connecting piece or valve body made of a thermoplastic plastic, which is not in the sense of a weldability with the container wall compatible. Then comes a welding with the container wall is not readily be considered, especially for valves and connecting pieces, which consist of materials such as POM (polyoxymethylene) or ABS (acrylonitrile-butadiene-styrene copolymer). It is known that polyethylene and polyoxymethylene are not weldable together. Therefore, it is known to see from POM existing valves or nipples with ver molded from PE or HDPE shank, which is welded in the region of the connection opening of the container with this, for example in Heizelement- welding process.
Die Herstellung von spritzgegossen Mehr-Komponenten Bauteilen aus beispielsweise POM und HDPE ist verhältnismäßig aufwendig, insbesondere ist es aufwendig, die betreffenden Bauteile nach Fertigstellung des Behälters mit der Behälterwand zu ver schweißen, beispielsweise mittels Schweißrobotern durch Rota tionsschweißen oder im Heizelement-Schweißverfahren unter Ver wendung von Schweißspiegeln. The production of injection-molded multi-component components such as POM and HDPE is relatively expensive, in particular it is expensive to weld the relevant components after completion of the container with the container wall to, for example by welding robots by Rota tion welding or in the heating element welding process under Ver use of welding mirrors.
