  Kolbenstopfen für Ampullen 
Die vorliegende Erfindung bezieht sich auf Kolbenstopfen für Ampullen, u. zw. auf solche, die ein   Zurückziehen,   ein sogenanntes Aspirieren, gestatten. 



   Bei Zylinderampullen werden bereits zwecks Aspiration   Gummi3topfen   verwendet, die einseitig ausgebohrt sind. Die Bohrung dient zur Aufnahme von Domen u. dgl., die aus der Kolbenspitze des Spritzgestelles austreten und eine feste Verbindung zwischen Kolbenstopfen und Kolbenstange herstellen. Diese sichere Verbindung ist zur Aspiration notwendig. 



   Bei der maschinellen Füllung von Ampullen tritt nunmehr das Problem auf, den Stopfen derart einzubringen, dass sein   ausgebohrtes   Ende nach aussen zeigt. Dies setzt eine Vorrichtung voraus, die die ent-

 unsicher. 



   Der   erfindungsgemässe   Stopfen aus Gummi oder einem anderen elastischen Material, der als Kolbenstopfen für Ampullen,   z.   B.   Spritzampullen oder Spritzpatronen,   dient, beseitigt den geschilderten Missstand, indem er beiderseits kleine Bohrungen aufweist, so dass es nunmehr beim maschinellen Einführen des Stopfens völlig gleichgültig ist, welche Seite zuerst in   dieZylinderampulle eingeschoben   wird. 



   In   der Zeichnung bedeutet 1 denStopfen ; 2 und 3   sind   die Bohrungen zur Aufnahme desmitAspirations-   häkchen oder-dornen ausgerüsteten Kopfes des Kolbens.

  Plunger stoppers for ampoules
The present invention relates to plunger plugs for ampoules, u. between those who allow a withdrawal, a so-called aspiration.



   In the case of cylindrical ampoules, rubber stoppers are already used for aspiration, which are drilled out on one side. The hole is used to accommodate domes u. Like. That emerge from the piston tip of the spray frame and establish a firm connection between the piston stopper and piston rod. This secure connection is necessary for aspiration.



   With the mechanical filling of ampoules, the problem now arises of inserting the stopper in such a way that its drilled end points outwards. This requires a device that has the
 EMI1.1
 unsure.



   The stopper according to the invention made of rubber or another elastic material, which is used as a plunger stopper for ampoules, e.g. B. injection ampoules or syringe cartridges, eliminates the problem described by having small bores on both sides, so that it is now completely indifferent when the stopper is mechanically inserted which side is inserted first into the cylinder ampoule.



   In the drawing, 1 denotes the plug; 2 and 3 are the bores for receiving the head of the piston equipped with aspiration hooks or spikes.
