KunststoffbehälterPlastic container

Gegenstand der Erfindung ist ein Kunststoffbehälter, im Rotationsgußverfahren hergestellt, mit einem zwei Vertiefungen in der Behälterwand miteinander verbindenden, unterhalb der Oberfläche des Behälters verlaufenden geschlossenen Kanal.The invention relates to a plastic container using the rotational molding process produced, with a connecting two recesses in the container wall, below the surface the container running closed channel.

Das Rotationsgußverfahren stellt wegen der kleinen auf das Werkzeug wirkenden Drücke und der dadurch bedingten niedrigen Werkzeugkosten ein ideales Verfahren für die Herstellung von Hohlkörpern, beispielsweise Behältern, in niedriger und mittlerer Stückzahl dar. Der Nachteil des Verfahrens besteht darin, daß Kanäle nur von der Behälteroberfläche aus erzeugt werden können, da· das Werkzeugteil, das den Kanal formt, .entformbar sein muß. Ein unterhalb der Oberfläche des Behälters verlaufender geschlossener Kanal, der zwei in der Behälterwand angeordnete Vertiefungen miteinander verbinden soll, ist daher mit der bekannten Formtechnik nicht herstellbar.The rotational molding process places on the tool because of the small size acting pressures and the resulting low tool costs an ideal process for the production of hollow bodies, for example containers, in low and medium numbers. The disadvantage of the method is that channels only from the Container surface can be generated from the fact that the tool part, that forms the channel. Must be demoldable. A closed channel running below the surface of the container, the is intended to connect two recesses arranged in the container wall with one another, is therefore not possible with the known molding technique manufacturable.

Der Erfindung liegt die Aufgabe zugrunde, bei einem im Rotationsgußverfahren hergestellten Behälter auch solche geschlossenen Kanäle zu ermöglichen, die lediglich in der Oberfläche des Behälters befindliche Vertiefungen, nicht aber die Außenseite des Behälters miteinander verbinden.The invention is based on the object of a rotational molding process Manufactured containers also allow such closed channels that are only in the surface of the container located wells, but not connect the outside of the container with each other.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß ein in die Form zur Herstellung des Behälters an die Stelle des zu bildenden Kanals eingefügtes, während des Gießverfahrens durch die Form aufgeheiztes, und als kunststoffummantelter Kern in dem geformten Behälter verbleibendes wärmeleitendes Rohr. Es versteht sich von selbst, daß das Rohr eine dem gewünschten Verlauf, und Querschnitt des Kanals entsprechende Form besitzt.This object is achieved according to the invention in that a in the form for the production of the container in place of the Forming channel inserted, heated by the mold during the casting process, and as a plastic-coated core in the thermally conductive tube remaining in the molded container. It goes without saying that the tube is one of the desired Course, and cross-section of the channel has a corresponding shape.

Anhand eines Ausführungsbeispiels wird die Erfindung näher erläutert. Die Zeichnung zeigt inThe invention is explained in more detail using an exemplary embodiment. The drawing shows in

stoffbehälter in Schnittdarstellung und inmaterial container in sectional view and in

5 Fig. 2 die Draufsicht dieses Behälters.5 Fig. 2 shows the top view of this container.

Der Behälter 1 besitzt zwei Vertiefungen 2, 3, die mittels eines geschlossenen Kanals miteinander verbunden werden sollen. Die zur Herstellung des Behälters 1 benutzte Form besitzt zwei Erhebungen, die die Vertiefungen 2, 3 bilden. Zwischen diese Erhebungen wird ein Rohr 4 eingelegt und in der Position des zu bildenden Kanals fixiert. Bei der Erwärmung der Form wird das Rohr 4 ebenfalls über die Schmelztemperatur des zur Herstellung des Behälters verwendeten Granulats erhitzt, so daß nicht nur an der Form, sondern auch an dem Rohr 4 der Kunststoff aufschmilzt.The container 1 has two recesses 2, 3 which are to be connected to one another by means of a closed channel. The mold used to manufacture the container 1 has two elevations which form the depressions 2, 3. A tube 4 is inserted between these elevations and fixed in the position of the channel to be formed. When the mold is heated, the tube 4 is also heated above the melting temperature of the granulate used to manufacture the container, so that the plastic melts not only on the mold but also on the tube 4.

Nach dem Abkühlen ist das Rohr 4 von außen vollständig von einer Kunststoffschicht 5 umgeben. Die Vertiefungen 2, 3 und der, durch das Rohr 4 erzeugte Kanal sind nahtlos und somit völlig dicht vom Innenraum 6 des Behälters 1 getrennt.After cooling, the tube 4 is completely surrounded on the outside by a plastic layer 5. The wells 2, 3 and the, through the ducts produced by the tube 4 are seamless and thus separated from the interior 6 of the container 1 in a completely sealed manner.
