Die Erfindung betrifft ein Verfahren zur Befestigung eines abgetrennten bzw. zusätzlichen Reservebehälters in einem aus Kunststoff bestehenden Kraftstofftank od. dgl. während dessen Blasformung sowie eine Vorrichtung zur Durchführung dieses Verfahrens.The invention relates to a method of fastening a separate or additional reserve container in a fuel tank made of plastic od. Like. During its blow molding and a device for performing this method.

In einem Kraftstofftank läuft die Flüssigkeit infolge der Fahrzeugbewegungen von einer Seite zur anderen. Deshalb kann es vorkommen/ daß in gewissen Augenblicken von der Ansaugstelle her Luft oder Luft mit Kraftstoff in den Motor gelangt. Um diese Erscheinung zu verhindern,werden entweder Zwischenwände vorgesehen, oder es wird ein besonderer Kraftstofftank-Vorratsbehälter vorgesehen. Diese Bauteile bewirken eine gewisse Verzögerung in der Kraftstoff bewegung an der Ansaugstelle. Dadurch wird sichergestellt, daß sich trotz der Flüssigkeitsbewegung im Kraftstofftank an der Ansaugstelle stets genügend Flüssigkeit befindet. Wenn der Vorratsbehälter, der nachfolgend auch als Reserve- oder Ausgleichsbehälter bezeichnet wird, zweckmäßig konstruiert ist, dann bleibt er für längere Zeit gefüllt, auch wenn im Kraftstofftank infolge der Fahrzeuglage keine Flüssigkeit mehr in der Nähe des Ausgleichstanks steht.In a fuel tank, the liquid flows from side to side as the vehicle moves. That's why it can happen / that at certain moments air or air with fuel from the intake point into the Engine. In order to prevent this phenomenon, partitions are either provided or a special one is made Fuel tank reservoir provided. These Components cause a certain delay in the movement of fuel at the intake point. This ensures that there is always enough liquid at the suction point in spite of the liquid movement in the fuel tank is located. If the storage tank, which is also referred to below as the reserve or equalization tank, Is properly designed, it will remain filled for a long time, even if in the fuel tank as a result of the Vehicle position, there is no longer any liquid near the expansion tank.

DagegenIt is because of this manufacturing process applied not difficult * the ftiisgieirhsb ^ hSit ^ r ^ r eh e TtinptiwnH to install a metal fuel tank. Against it

ist es bisher nicht möglich gewesen, den Ausgleichsbehälter an der Innenwand eines durch Blasformung gefertigten Kunststofftanks anzubringen. Der Grund dafür ist, daß es nicht möglich ist, in der Wand des Kraftstofftanks eine öffnung vorzusehen, die so groß ist, daß an ihrer Stelle der Vorratsbehälter durch die öffnung hindurch montiert werden könnte. Eine öffnung dieser Größe kann den Kraftstofftank undicht machen. Der vorliegenden Erfindung liegt die Aufgabe zugrunde, diesen Nachteil zu beseitigen.it has so far not been possible to use the expansion tank to be attached to the inner wall of a blow molded plastic tank. The reason for this is that it is not possible in the wall of the fuel tank to provide an opening which is so large that in its place the reservoir through the Could be mounted through the opening. An opening this size can cause the fuel tank to leak. The present invention is based on the object to eliminate this disadvantage.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der auf der Blasluftlanze oder einer anderen Befestigungsvorrichtung aufgesetzte Vorratsbehälter während der Blasformung innerhalb des verformbaren Kunststoffschlauchs angeordnet ist. Sofort nach Einsetzen der Blasformung führt die Befestigungsvorrichtung den Vorratsbehälter unter genügend großem Anpreßdruck genau an seinen richtigen Platz an der Innenwand des heißen, sich verformenden Kunststoffschlauchs. Dadurch wird der Vorratsbehälter während der Blasformung an der Innenwand des Kraftstofftanks fest und endgültig angebracht. Weitere Einrichtungen werden dafür nicht benötigt.This object is achieved according to the invention in that the storage container placed on the blown air lance or another fastening device during blow molding is arranged within the deformable plastic tube. Immediately after the blow molding has started the fastening device guides the storage container exactly to its correct position under sufficiently high contact pressure Space on the inside wall of the hot, deforming plastic hose. This becomes the reservoir firmly and definitively attached to the inner wall of the fuel tank during blow molding. Other facilities are not required for this.

Das gleiche Verfahren kann immer dann angewendet werden, wenn es notwendig ist, einen zusätzlichen Hilfsbehälter oder zusätzliche Bauteile an der Innenwand eines durch Blasformung gefertigten Tanks oder HauptbehältersThe same procedure can be used whenever there is a need for an additional auxiliary tank or additional components on the inner wall of a blow molded tank or main container

Eine Vorrichtung zur Durchführung des Verfahrens gemäß der Erfindung bzw. ein auf diese Weise hergestellter Behälter besteht gemäß Fig. 1 der Zeichnung im wesentlichen aus einer Grundplatte oder Formenträger 1, einer Form 2, einer Blasluftlanze oder Blasrohr 3 mit Befestigungsmechanismus, und einem Reserve- oder Vorratsbehälter 4 mit seiner Montagearmatur. Mit 5 ist in Fig. 1 ein Formkörper oder ein Blasrohling bzw. Kunststoffschlauch bezeichnet. Beispielsweise kann der kleinere Reservebehälter 4 nach seiner Einführung in den größeren Hauptbehälter bzw. in den Blasrohling mit Hilfe des Blasrohres 3 in Richtung des in Fig. 1 eingezeichneten Pfeiles an die Innenwandung des heißen, sich verformenden Blasrohlings, KunststoffSchlauches bzw. Hauptbehälters verschwenkt werden, wo er dann festgehalten wird.An apparatus for carrying out the method according to the invention or one produced in this way According to FIG. 1 of the drawing, the container consists essentially of a base plate or mold carrier 1, a Form 2, a blown air lance or blowpipe 3 with a fastening mechanism, and a reserve or storage container 4 with its assembly fitting. With 5 in Fig. 1 denotes a molded body or a blow molding or plastic tube. For example, the smaller Reserve container 4 after its introduction into the larger main container or into the parison with the help of Blow pipe 3 in the direction of the arrow shown in Fig. 1 on the inner wall of the hot, deforming Blow blank, plastic hose or main container be pivoted, where it is then held.

Kleinere Behälter oder andere Bauteile können auch für die folgenden Zwecke an den Innenwänden größerer Behälter erforderlich sein: Transport und Lagerung von Flüssigkeiten, die aus zwei Komponenten bestehen, z.B. Farben, Klebstoffe und so fort. Die Anbringung solcher kleinerer Behälter oder sonstiger Elemente in einem größeren Behälter kann nach dem Verfahren gemäß der Erfindung leicht vorgenommen werden.Smaller containers or other components can also be attached to the inner walls of larger containers for the following purposes may be required: transport and storage of liquids that consist of two components, e.g. Paints, adhesives and so on. The attachment of such smaller containers or other elements in one larger container can easily be made according to the method according to the invention.
