Description

Die Erfindung betrifft einen Schraubdeckel aus Kunststoff mit einer Deckelscheibe und einem an deren Umfang sich rechtwinklig anschließenden äußeren Deckelrand mit Innengewinde zum Verschließen eines Befüll- und/oder Entnahmestutzens eines Behälters zum Transport und zur Lagerung von Flüssigkeiten sowie mit einem in der Deckelscheibe versenkt angeordneten zentralen Spundstutzen mit Innengewinde zum Einschrauben eines Spundstopfens.The invention relates to a screw cap made of plastic with a cover disc and an outer edge of the lid with internal thread at the circumference at right angles for closing a filling and / or removal nozzle of a container for the transport and storage of liquids as well as with a sunk in the cover disc central spigot with internal thread for screwing in a bung stopper.

Aus der EP 0 650 446 B1 bekannte Schraubdeckel der gattungsgemäßen Art zum Verschließen des Einfüllstutzens eines Spundfasses oder des Kunststoff-Innenbehälters eines Palettenbehälters mit einem Außenmantel aus Gitterstäben oder Blech haben den Nachteil, dass der Dichtring zur Abdichtung des Spundstopfens in dem Spundstutzen des Schraubdeckels mit der Zeit aufgrund von Alterungserscheinungen des Herstellungsmaterials des Dichtringes besonders bei Behältern zum Transport und zur Lagerung von chemischen Flüssigkeiten die Dichtigkeit des Spundstopfenverschlusses nicht mehr gewährleistet, so dass der Dichtring regelmäßig ausgetauscht werden muss.From the EP 0 650 446 B1 known screw cap of the generic type for closing the filler neck of a bung barrel or the plastic inner container of a pallet container with an outer sheath of bars or sheet have the disadvantage that the sealing ring for sealing the bung in the bung of the screw with time due to aging of the manufacturing material of Sealing ring especially for containers for the transport and storage of chemical liquids, the tightness of the bung stopper closure no longer guaranteed, so that the sealing ring must be replaced regularly.

Der Erfindung liegt die Aufgabe zugrunde, den Schraubdeckel der gattungsgemäßen Art im Hinblick auf eine verbesserte Dichtigkeit des Spundstopfenverschlusses, eine kostengünstigere Herstellung sowie eine Senkung der Betriebskosten der mit dem Schraubdeckel ausgestatteten Flüssigkeitsbehälter, die als Mehrwegbehälter zum Einsatz kommen, zu verbessern.The invention is based on the object, the screw of the generic type in terms of improved tightness of the bung stopper, a cheaper production and a reduction in operating costs of the Schraubdeckel equipped liquid containers, which are used as reusable containers used to improve.

Diese Aufgabe wird erfindungsgemäß gelöst durch einen Schraubdeckel gemäß den Merkmalen der Patentansprüche 1, 7 und 8.This object is achieved by a screw cap according to the features of claims 1, 7 and 8.

Die Unteransprüche beinhalten vorteilhafte und zweckmäßige Weiterbildungen der Erfindung.The subclaims contain advantageous and expedient developments of the invention.

Der erfindungsgemäße Schraubdeckel mit einem Spundstutzen, der mit einem Spundstopfenverschluss ausgestattet ist, zeichnet sich durch folgende Vorteile aus:The screw cap according to the invention with a bung, which is equipped with a bung stopper, characterized by the following advantages:

Die Ausstattung des Kunststoff-Spundstopfens zum Verschließen des Spundstutzens des Schraubdeckels mit einer einteilig mit diesem spritzgegossenen konischen Mehrfachdichtung in Form von beabstandeten Dichtringen, die bei eingeschraubtem Spundstopfen gegen eine konische innere Dichtfläche des Spundstutzens angepresst wird, ermöglicht eine optimale Dichtigkeit des Spundstopfenverschlusses. Bei Behältern mit Innendruck wird die Dichtigkeit des Spundstopfenverschlusses für den Spundstutzen des Schraubdeckels weiterhin noch dadurch verbessert, dass der durch das Einschrauben des Spundstopfens bewirkte Anpressdruck der Dichtringe der konischen Mehrfachdichtung des Stopfens gegen die konische innere Dichtfläche des Spundstutzens durch den auf die Innenwand des mit der Mehrfachdichtung versehenen Abdichtendes der Einschraubhülse des Spundstopfens wirkenden Innendruck des Behälters noch zusätzlich erhöht wird. Durch den Wegfall eines Dichtringes, der regelmäßig ausgetauscht werden muss, können die Herstellungskosten gegenüber bekannten Schraubdeckeln mit einem Spundstutzen, der durch einen Spundstopfen mit Dichtring verschlossen wird, und die Unterhaltungskosten für Flüssigkeitsbehälter, die mit einem Schraubdeckel mit dem neuen Spundstopfenverschluss für den Spundstutzen des Deckels ausgerüstet sind und die als Mehrwegbehälter zum Einsatz kommen, wesentlich gesenkt werden.The equipment of the plastic bung stopper for closing the bung of the screw with a molded injection molded with this conical multiple seal in the form of spaced sealing rings, which is pressed with screwed bung against a conical inner sealing surface of the bung, allows optimal tightness of the bung stopper. In containers with internal pressure, the tightness of the bung stopper for the bung of the screw cap is further improved by the effect caused by screwing the bung stop contact pressure of the sealing rings of the conical multiple seal of the plug against the conical inner sealing surface of the bung through the on the inner wall of the Multiple seal provided sealing the Einschraubhülse the bung stopper acting internal pressure of the container is additionally increased. By eliminating a sealing ring that needs to be replaced regularly, the manufacturing costs compared to known screw caps with a bung, the through a bung stopper with sealing ring is closed, and the maintenance costs for liquid containers, which are equipped with a screw cap with the new bung stopper for the bung of the lid and are used as reusable containers, are substantially reduced.
