Bei den bekannten Vorrichtungen zum Feststellen von Undichtheiten an Dosenverschlüssen besteht der Nachteil einet nicht einwandfreien Befestigung an den zu prüfenden Dosen. Um diesem Übelstand abzuhelfen, besteht das erfindungsgemäße Prüfgerät aus zwei Hauptteilen, von denen der eine Teil bei Beginn der Prüfung in die zu prüfende Dose hineingelegt wird, die hiernach verschlossen wird. Dieser untere Teil der Prüfvorrichtung besteht aus einer mit einer Gummidichtung überzogenen Metallplatte, an der in der Mitte ein Stutzen befestigt ist. Durch eine im Dosendeckel herzustellende Öffnung wird diesei-Stutzen nach außen geführt, wo er eine ebenfalls- mit einer Gummidichtung versehene Metallplatte aufnimmt. Beide Platten werden durch eine Flügelschraube zusammengepreßt, wodurch eine sichere Abdichtung des Dosenverschlusses erzielt wird.In the known devices for detecting leaks in can closures there is the disadvantage of an incorrect attachment to the cans to be tested. To remedy this evil, the test device according to the invention consists of two main parts, one of which is part of The start of the test is placed in the can to be tested, which is then closed will. This lower part of the test device consists of one with a rubber seal coated metal plate to which a nozzle is attached in the middle. Through an im The opening to be made in the can lid is the egg nozzle led to the outside, where he also provided with a rubber seal Metal plate accommodates. Both plates are pressed together by a wing screw, whereby a secure sealing of the can closure is achieved.
In der Abbildung ist der Gegenstand der Erfindung in einer beispielsweisen Ausführungsform in Ansicht mit teilweisem Schnitt dargestellt.In the figure is the subject matter of the invention in an exemplary embodiment shown in partial section view.
Die untere Abdichtungsplatte ist mit 1, die daraufliegende Gummidichtung mit 2 und der an der Dichtungsplatte befestigte Ventilstutzen mit 7 bezeichnet. Der obere Teil der Prüfvorrichtung besteht in der Hauptsache· aus der Gummidichtung 3 und der Metall-, platte 4. Mittels der Flügelschraube 5 werden die Teile für die Innen- und Außendichtung fest zusammengepreßt. Im Stutzen 7 ist ein an sich bekanntes Ventil 6 eingesetzt, durch welches die zur Prüfung erforderliche Luft mittels einer ebenfalls zu diesem Zweck bekannten Luftpumpe in das Doseninnere eingeführt wird. Der im Innern der Dose herrschende Druck kann in bekannter Weise mit einem Manometer 8 gemessen werden.The lower sealing plate is marked with 1, the rubber seal with 2 and the valve connector attached to the sealing plate is designated by 7. The upper part of the The main part of the test device consists of the rubber seal 3 and the metal, plate 4. Using the wing screw 5, the parts for the inner and outer seal tightly pressed together. In the nozzle 7 a known valve 6 is used, through which the air required for the test by means of a also known for this purpose Air pump is introduced into the inside of the can. The one prevailing inside the can Pressure can be measured in a known manner with a manometer 8.
Die Prüfung der Dosenverschlüsse auf Dichtheit erfolgt dann in bekannter Weise durch Eintauchen der Dosen mit daran angebrachtem Prüfgerät in Wasser, wobei die kleinsten Undichtheiten, wie bereits bekannt, an dem Hochsteigen von Luftblasen erkennbar werden.The can closures are then tested for leaks in a known manner by immersing the cans with attached test device in water, whereby the The smallest leaks, as already known, can be recognized by the rising of air bubbles will.
