Description

Sicherheitsverschraubung für Wärmflaschen o. dgl. Gegenstand derErfindung ist eine Sicherheitsverschlußschraube für Wärmflaschen, welche in zweifacher Hinsicht einen Schutz gegen Beschädigung der Wärmflasche bieten soll; einmal soll sie verhüten, daß die Wärmflasche, weil sie gefüllt und verschlossen auf das Feuer gestellt wird, explodiert, und anderseits soll sie ein Zusammenziehen und Verbeulen der Wärmflasche verhindern, wenn in ihr durch Erkalten des eingefüllten Wassers ein Vakuum entsteht.Safety screw connection for hot water bottles or the like. Subject of the invention is a safety screw plug for hot water bottles, which works in two ways to provide protection against damage to the hot water bottle; once she should prevent that the hot water bottle, because it is filled and closed, is placed on the fire, explodes, and on the other hand it is said to contract and dent the hot water bottle prevent if a vacuum is created in it by cooling the water filled in.

Das Wesen der Erfindung besteht darin, daß in der Bleidichtungsscheibe der sonst üblichen Verschlußschraube ein kleines Messingröhrchen eingelötet ist, das mit einem Stoff ausgefüllt wird, der zuläßt, daß bei zu hohem Druck des Wärmflascheninhalts Dampf ausströmen oder bei eintretendem Vakuum Luft von außen einströmen kann.The essence of the invention is that in the lead washer a small brass tube is soldered into the otherwise usual screw plug, which is filled with a substance that allows the contents of the hot water bottle to be released if the pressure is too high Steam can flow out or air can flow in from outside if a vacuum occurs.

Auf der Zeichnung ist eine Verschlußschraube mit eingebauter Sicherheitspatrone im Vertikalschnitt dargestellt.On the drawing is a screw plug with a built-in safety cartridge shown in vertical section.

In der Hartbleidichtung a der sonst üblichen Verschlußschraube b ist ein kleines Messingröhrchen e eingelötet, das nach unten eine kleine Öffnung hat und nach oben offen ist. In dieses Röhrchen wird ein Stückchen Schwamm d oder ein ähnlicher elastischer und durchlässiger Stoff dicht eingepreßt und der Rand des Röhrchens leicht umgebördelt, damit das Schwämmchen festgehalten wird.In the hard lead seal a is the otherwise usual screw plug b soldered in a small brass tube that has a small opening at the bottom and is open at the top. A piece of sponge d or a is placed in this tube similar elastic and permeable fabric tightly pressed and the edge of the The tube is slightly flanged so that the sponge is held in place.

Diese so beschaffene Sicherheitspatrone hat die Wirkung, daß bei zu hohem überdruck in der Wärmflasche Dampf ausströmen und bei eintretendem Unterdruck infolge Abkühlens des heißen Wassers Luft von außen einströmen kann. Gleichzeitig dichtet die Sicherheitspatrone die Wärmflasche ab und verhütet ein Auslaufen des Wassers während des Gebrauchs.This so created safety cartridge has the effect that at to high overpressure in the hot water bottle, and when a negative pressure occurs As a result of the cooling of the hot water, air can flow in from the outside. Simultaneously the safety cartridge seals the hot water bottle and prevents the Water during use.

PATENTANSPRUCH: Sicherheitsverschraubung für Wärmflaschen o. dgl. zur Verhinderung von zu hohem Über- und Unterdruck, dadurch gekennzeichnet, daß in die Bleidichtungsscheibe (a) der sonst üblichen Verschlußschraube (b) eine Sicherheitspatrone eingesetzt ist, bestehend aus einem Röhrchen (c) mit einer Füllung aus porösem Stoff - z. B. eingepreßtem Schwämmchen (d) -, der für die Flüssigkeit undurchlässig ist und Dampf oder Luft nur bei zu hohem Druck auf der einen oder andern Seite hindurchtreten läßt. PATENT CLAIM: Safety screw connection for hot water bottles or the like to prevent excessive overpressure and underpressure, characterized in that a safety cartridge, consisting of a tube (c) with a Filling made of porous material - e.g. B. pressed-in sponge (d) - which is impermeable to the liquid and only allows steam or air to pass through on one side or the other if the pressure is too high.
