Description

Undichtigkeitsanzeiger für Konservengläser. Die Erfindung betrifft eine Vorrichtung, welche sofort anzeigen soll, wenn Konservengläser undicht geworden sind, damit die Schimmelbildung verhütet werden kann. Die Vorrichtung besteht in bekannter; Weise aus einem am einen Ende zugeschmolzenen oder mit Stopfen dicht verschlossenen Glasröhrchen, in das gemäß der Erfindung eine farbige Schwimmkugel eingesetzt ist. D:e Kugel ist am Herausfallen aus dem Röhrchen gehindert, beispielsweise dadurch, daß die Öffnung desselben etwas verengt ist. Wird die Vorrichtung mit der Öffnung nach unten beim Einkochen der Früchte o. dgl. zusammen mit diesen in das Konservenglas in der Nähe der Wandung eingesetzt, . so dehnt sich auch in dem Röhrchen die Luft aus. Die Einmachflüssigkeit kann daher nicht in das Röhrchen eintreten und die Schwimmkugel liegt unten im Röhrchen. Sobald aber das Konservenglas undicht wird, wird die Flüssigkeit mit der Schwimmkugel in dem Röhrchen hochgedrückt. An dem Stand der bunten Schwimmkugel in dem Röhrchen ist also zu erkennen, ob das Konservenglas dicht oder undicht ist.Leak indicator for canning jars. The invention relates to a device that is supposed to indicate immediately if canning jars become leaky so that the formation of mold can be prevented. The device consists of known; Way from a sealed at one end or with a stopper sealed glass tube, in which according to the invention a colored floating ball is used. The ball is prevented from falling out of the tube, for example in that the opening of the same is narrowed somewhat. If the device with the Opening downwards when boiling the fruits or the like together with them in the Canning jar inserted near the wall,. so also expands in the tube the air out. The canning liquid can therefore not enter the tube and the floating ball is at the bottom of the tube. But as soon as the jar is leaking the liquid is pushed up in the tube with the floating ball. At The position of the colorful floating ball in the tube shows whether the jar is is tight or leaking.

Die Zeichnung stellt ein Ausführungsbeispiel des Anzeigers, in ein Glas eingesetzt, im Querschnitt dar. Die Kugel ist noch unten im Röhrchen liegend gezeichnet, d. h. das Konservenglas ist bei dieser Stellung dicht.The drawing represents an embodiment of the indicator in a Glass inserted, shown in cross section. The ball is still in the bottom of the tube drawn, d. H. the jar is tight in this position.

i ist das Röhrchen des Anzeigers, welches unten bei a etwas zusammengezogen ist; 3 ist die farbige und hohle Schwimmkugel, .4 das Konservenglas.i is the tube of the indicator, which is contracted a little at the bottom at a is; 3 is the colored and hollow floating ball, .4 is the canning jar.
