"Trinkbeutel und verfahren zu seiner Herstellung, Zusatz zur Patentanmeldung vom 16.4.1964 (Lh 120)"
In der Hauptanmeldung wurde zum Herstellen von Trinkbeuteln vorgeschlagen, daß von einem Seitenfaltenschlauch ausgegangen wird und die zwischen den Beutelwandungen liegende Faltung auf ganzer oder teilweiser Länge, vorzugsweise in der späteren Beutelmitte aufgeschnitten und anschließend am Rand oder im nahen Bereich des Randes die Seitenfalten und die Beutelwandungen und somit vier Folienlagen miteinander Ms auf einen vorzugsweise in Beutelmitte liegenden Spalt als Blnführkaiml für einen Trinkhalm miteinander verschweißt und anschließend Querabschweißungen zum Herstellen des Beutels vorgenommen werden. Weiterhin wurde vorgeschlagen, daß das Auf schneiden der zwischen den Beutelwandungen liegenden Faltung ' am unteren Ende des Sinführkanals für den Trinkhalm durch den in den Beutel einzuführenden Trinkhalm erfolgt, der vorzugsweise aus PVC besteht und angespit&t ist. ■ ,

Es hat sich gezeigt, daß ausgehend von der Lösung, die Faltung durch den Trinkhalm selbst aufzustoßen, ein dichter Abschluß der so erhaltenen Einführöffnung nach dem Herausziehen des Trinkhalms auch dann erreicht wird, wenn die Seitenfalten selbst nicht im nahen Bereich der Trinkhalmeinführöffnung einander haften oder zur Haftung miteinander verbunden sind«
Der vereinfachte, aus einem Seitenfaltenschiauch hergestellte Trinkbeutel ist erfindungsgemäß dadurch gekennzeichnet, daß zur Abdichtung des Durchlasses für den Trinkhalm ausschließlich die Beutelwandungen und die Seitenfalten am Kopfende des Beutels oder in dessen nahen Bereich bis auf eine öffnung für den Durchtritt des Trinkhalms, die sich vorzugsweise in der Mitte des Beutels befindet, verschweißt sind.
Zur Herstellung des verbesserten Beutels wird vorgeschlagen, daß ausgehend von einem Seitenfaltenschlauch die Seitenfalten mit den Beutelwandungen, im Bereich der Längskante des Schlauches oder im naiimm. Bereich der Längskante des Schlauches bis auf eine DurchtrittE-öffnung für den einzuführenden Trinkhalm verschweißt und anschliessend die Seitennahtschweißung zum Schließen des Beutels und das Abtrennen vom Schlauch vorgenommen wird»
