Description

gegen eine Abdichtung 13 anlegt, die beispielsweise aus Polytetrafluorethylen besteht. Hierdurch wird eine absolute Abdichtung gegenüber dem die Zündpatrone aufnehmenden Gehäuse 14 erreicht, das seinerseits gegenüber dem Hals des Behälters 10 durch Löten u. dgl. abgedichtet ist. Der Stopfen 11 wird in seiner Stellung gehalten, wobei ein geeigneter Druck auf die Abdichtung 13 von einem lösbaren Klemmglied in Form eines Sicherungsrings 15 ausgeübt wird, welcher sich gegen das eine Ende der Büchse 16 anlegt. Das andere Ende der Büchse 16 legt sich gegen die der Abdichtung 13 abgewandte Seite des Flansches 11 b des Stopfens 11 an. Der Sicherungsring 15 trägt an seinem Außenumfang ein Gewinde, welches in ein Innengewinde 14 α eingreift, das an demjenigen Ende des die Zündpatrone aufnehmenden Gehäuses 14 liegt, welches vom Hals des Behälters 10 abgewandt ist. Es ist Vorsorge getroffen, daß der Sicherungsring 15 verdreht werden kann, so daß der erforderliche Dichtdruck erreicht werden kann. So kann beispielsweise die Innenfläche dieses Sicherungsringes 15 zur Aufnahme eines Werkzeuges mit einem Sechskant als Sechkant ausgebildet sein. Es können auch Dichtringe vorgesehen werden, wie sie in der Zeichnung beispielsweise mit 20 angedeutet sind. Diese Dichtungsringe 20 sollen ein vorzeitiges Ausströmen der Explosionsgase verhindern. applies against a seal 13, which consists for example of polytetrafluoroethylene. In this way, an absolute seal is achieved with respect to the housing 14 which receives the ignition cartridge and which in turn is sealed against the neck of the container 10 by soldering and the like. The stopper 11 is held in its position, a suitable pressure being exerted on the seal 13 by a releasable clamping member in the form of a locking ring 15 which rests against one end of the sleeve 16. The other end of the sleeve 16 rests against the side of the flange 11 b of the plug 11 facing away from the seal 13. The locking ring 15 carries at its outer periphery a thread which engages in an internal thread α 14, which is located at that end of the primer cartridge-receiving housing 14, which faces away from the neck of the container 10th Provision has been made that the locking ring 15 can be rotated so that the required sealing pressure can be achieved. For example, the inner surface of this locking ring 15 can be designed as a hexagon for receiving a tool with a hexagon. Sealing rings can also be provided, as indicated by 20 in the drawing, for example. These sealing rings 20 are intended to prevent the explosion gases from escaping prematurely.

Die Büchse 16 besitzt in ihrer Wandung eine Bohrung 16 a, so daß die Explosionsgase der Zündpatrone 12 in eine in der Nähe des dünnen Randes 11 a liegenden Ringnut 11 c des Stopfens 11 überströmen können. Nach dem Einbau des Stopfens 11, der Büchse 16 und des Sicherungsringes 15 wird auf das die Zündpatrone 12 aufnehmende Gehäuse 14 ein Verbindungsstück 17 aufgeschraubt. Dieses Verbindungsstück 17 nimmt ein aus Metall bestehendes Führungsrohr 18 auf, welches in den Sicherungsring 15 hineinragt und an seinem oberen Ende 18 c so geformt ist, daß es sich gegen die Innenwandung des Sicherungsringes 15 anlegt. In einem mittleren Teil seiner Länge besitzt das Führungsrohr 18 zwei oder mehrere, nach innen gebogene, elastische Zungen 18 a, so daß — wenn der losgelöste Teil des Stopfens 11 unter der Einwirkung der Explosionsgase nach unten in das Verbindungsstück 17 geschleudert wirdThe sleeve 16 has a bore 16 a in its wall, so that the explosion gases from the ignition cartridge 12 can flow over into an annular groove 11 c of the plug 11 located in the vicinity of the thin edge 11 a. After the stopper 11, the sleeve 16 and the locking ring 15 have been installed, a connecting piece 17 is screwed onto the housing 14 that accommodates the ignition cartridge 12. This connecting piece 17 receives a guide tube 18 made of metal, which protrudes into the retaining ring 15 and is shaped at its upper end 18 c so that it rests against the inner wall of the retaining ring 15. In a central part of its length, the guide tube 18 has two or more, inwardly curved, elastic tongues 18 a, so that - when the detached part of the plug 11 is thrown down into the connector 17 under the action of the explosion gases

ίο — der Stopfen 11 sich an den Zungen 18 α vorbeibewegen kann.ίο - the plug 11 can move past the tongues 18 α .

Jedoch wird ein Rückprall des losgelösten Teiles des Stopfens 11, welcher die Auslaßöffnung blockieren könnte, durch die freien Enden der Zungen 18 a gesperrt. Bei seiner Bewegung nach unten verschiebt der losgelöste Teil des Stopfens 11 auch einen Anzeigezapfen 19, dessen unteres Ende dann aus dem Verbindungsstück 17 nach außen ragt, so daß die Entleerung des Behälters optisch angezeigt wird.However, a rebound of the detached part of the plug 11, which could block the outlet opening, is blocked by the free ends of the tongues 18 a . During its downward movement, the detached part of the stopper 11 also displaces an indicator pin 19, the lower end of which then protrudes outward from the connecting piece 17, so that the emptying of the container is visually indicated.

Das Führungsrohr 18 besitzt Bohrungen 18 b, welche den Durchtritt des aus dem Behälter entleerten Mediums gestatten.The guide tube 18 has bores 18 b, which allow the passage of the medium emptied from the container.

Die vorstehend beschriebene Anordnung erleichtert die Wiederinstandsetzung des Behälters nach seiner Entleerung. So kann der Behälter wieder aufgefüllt werden und durch Einführung eines neuen Verschlußgliedes 11 dann erneut verschlossen werden. Dies geschieht durch Abschrauben des Verbindungsstückes 17 zusammen mit dem darin gelagerten Führungsrohr 18, Lösen des Sicherungsringes 15 und Zurückziehen der Büchse 16 und des zurückgehaltenen Teiles des Stopfens 11. Hinzu kommt das Einsetzen einer neuen Zündpartone 12. Wenn die Büchse 16, der Sicherungsring 15 oder das Führungsrohr 18 beschädigt sind, kann ein Ersatz vorgenommen werden, wenn diese Teile mit dem neuen Stopfen 11 wieder zusammengebaut werden.The arrangement described above facilitates the repair of the container after its Emptying. So the container can be refilled and by introducing a new closure member 11 can then be closed again. This is done by unscrewing the connector 17 together with the guide tube 18 stored therein, loosening the locking ring 15 and Withdrawal of the sleeve 16 and the retained part of the plug 11. In addition, there is the insertion a new ignition cartridge 12. If the sleeve 16, the locking ring 15 or the guide tube 18 are damaged, a replacement can be made when these parts with the new plug 11 again be assembled.
