Description

Gegenstand der Erfindung ist ein gasdichter Abschluß des Deckels von Gefäßen mit innerem Überdruck. Es sind bereits Flaschenverschlüsse bekannt, bei denen ein Gummiring durch. Aufpressen des Verschlusses auf seine Dichtungsflächen gepreßt wird. Damit ist der Grad der Dichtung erschöpft. Steigt der innere Druck im Gefäß, so wird der Gummiring in sich mehr zusammengepreßt, ohne daßThe invention relates to a gas-tight Closure of the lid of vessels with internal overpressure. There are already bottle caps known where a rubber ring through. Pressing the closure is pressed onto its sealing surfaces. So is the degree of poetry exhausted. If the internal pressure in the vessel increases, the rubber ring becomes more compressed in itself without that

Abb. 2 diese Abdichtung zwischen Gefäß und Deckel noch einmal in vergrößertem Maßstab veranschaulicht ist.
Der Deckel 2 wird mittels des Gewindes 3 über das Gefäß 1 geschraubt, wobei bei 4 noch eine Abdichtung bekannter Art angeordnet sein kann. Die Außenwand des Gefäßes zeigt dien Absatz 9, und der Gef äßcteckel hat die erweiterte Ausbohrung 5, die durch den Boden 6 konisch abgeschlossen ist. Vor ay dem Aufschrauben des Deckels wird über die Außenwand des Gefäßes der U-förmige Metallring 7 in der dargestellten Weise übergeschoben. Nach dem festen Aufschrauben des Deckels 2 wird der Metallring 7 so weit nach innen gedrückt, daß der eine Schenkel gegen die konische Fläche 6 stößt. Der Innenraum des U-förmigen Ringes steht also in Verbindung mit der Gewindefuge 3. 8 ist die Ausgußmasse, ζ. B. Zinnlot, das in die Fuge hineingegossen ist und an dem Absatz 9 sein Rücklager findet. Tritt infolge inneren Überdrucks Gas durch das Gewinde nach außen, so gelangt es in den Innenraum des U-förmigen Ringes 7 und preßt diesen, je höher der innere Druck ist, desto energischer gegen Gefäß und Deckelwand, wodurch der dauernde luftdichte Abschluß gewährleistet ist. Zum Zweck des Lösens des Deckels ist es nur nötig, das Zinnlot mittels Gebläseflamme herauszuschmelzen. Fig. 2 shows this seal between the vessel and lid once again on an enlarged scale.
The lid 2 is screwed over the vessel 1 by means of the thread 3, it being possible for a seal of a known type to be arranged at 4. The outer wall of the vessel shows the paragraph 9, and the vessel cover has the enlarged bore 5 which is conically closed by the bottom 6. Before the lid is screwed on, the U-shaped metal ring 7 is pushed over the outer wall of the vessel in the manner shown. After the cover 2 has been screwed on firmly, the metal ring 7 is pressed inward so far that one of the legs abuts against the conical surface 6. The interior of the U-shaped ring is therefore in connection with the threaded joint 3. 8 is the pouring compound, ζ. B. tin solder, which is poured into the joint and finds its back bearing at paragraph 9. If gas escapes through the thread as a result of internal overpressure, it gets into the interior of the U-shaped ring 7 and presses it, the higher the internal pressure, the more energetically against the vessel and cover wall, whereby the permanent airtight seal is ensured. For the purpose of loosening the lid, it is only necessary to melt out the tin solder using a blower flame.
