Description

Doppelampulle. Das Hauptpatent 366 385 betrifft eine Doppelampulle, deren beide Teilbehälter durch eine Kapillare voneinander getrennt sind, die durch einen Pfropfen aus einer Mischung von Wachs und Paraffin verschlossen ist. Nach. dem zu dem genannten Patent erteilten Zusatzpatent 409 648 wird ein Pfropfen aus einer leicht schmelzenden Metallegierung benutzt. Wie bei dem Zusatzpatent bereits angedeutet, wird diese Metallegierung von Lösungen chemischer Stoffe, insbesondere Säuren, leicht angegriffen, so daß sie durch Einbringung einer ganz dünnen Decke aus chemisch indifferentem Material, z. B. Paraffin, gegen die chemische Einwirkung geschützt werden muß. Die Anbringung dieser Schutzdecke erfordert einen besonderen Handgriff und kann unter Umständen die Passage zwischen den beiden Gefäßen bei der Schmelzung der Verschlußmasse vor Ingebrauchnahme erschweren.Double ampoule. The main patent 366 385 relates to a double ampoule, whose two sub-containers are separated from each other by a capillary through which a plug made of a mixture of wax and paraffin is closed. To. the additional patent 409 648 granted to the said patent is a plug an easily melting metal alloy. As with the additional patent indicated, this metal alloy of solutions of chemical substances, in particular Acids, easily attacked, so that they can be removed by putting in a very thin blanket made of chemically indifferent material, e.g. B. paraffin, against the chemical action must be protected. The installation of this protective cover requires a special one Handle and can, under certain circumstances, the passage between the two vessels at the Make it more difficult to melt the sealing compound before use.

Gemäß der Erfindung wird diese Unzuträglichkeit in einfacher Weise dadurch überwunden, daß statt des schmelzbaren indifferenten Materials ein Luftkissen zwischen den Verschlußpfropfen und die Flüssigkeit gebracht wird. Das erfolgt nach der aus der Zeichnung ersichtlichen Weise dadurch, daß die Kapillare b, welche die die Flüssigkeit d enthaltende Ampulle & von der den festen Körper enthaltenden Ampulle c trennt, in ihrem mittleren Teil eine Ausbauchung! erhält, während sie oben und unten bei k und L verjüngt ist.According to the invention, this inconvenience is overcome in a simple manner in that, instead of the fusible inert material, an air cushion is placed between the closure plug and the liquid. This takes place in the manner evident from the drawing in that the capillary b, which separates the ampoule containing the liquid d from the ampoule c containing the solid body, has a bulge in its middle part! while it is tapered above and below at k and L.

Bei der Füllung wird zunächst die Verjüngung L durch den Ampulllenpfropfen f abgeschlossen und dann in a die Flüssigkeit eingegossen. Durch die Verjüngung k kann die Luft nicht entweichen, so daß das Luftkissen in i der Flüssigkeit d und dem Metallpfropfen verbleiben muß. Wird der Metallpfropfen f geschmolzen, so wird die in i verbliebene Luft durch die Flüssigkeit d nach c hinübergedrückt, besonders leicht dann, wenn zwischen u und c .eine Druckdifferenz hergestellt war.When filling, the taper L is first closed by the ampoule stopper f and then the liquid is poured into a. The air cannot escape through the taper k, so that the air cushion must remain in the liquid d and the metal plug. If the metal plug f is melted, the air remaining in i is pushed over by the liquid d to c, particularly easily when a pressure difference has been established between u and c.

Claims (1)

PATENTANSPRUCII: Doppelampulle nach Patent 409 648, dadurch gekennzeichnet, daß die Verbindungskapillare (b) in ihrem mittleren Teil-(!) innen ausgeweitet, oben und unten aber in dem Maße verjüngt ist, daß nach Verschluß der unteren Verjüngung (L) keine Flüssigkeit durch die obere Verjüngung (k) hindurch zur Erweiterung (i) treten kann, so daß in dieser ein Luftkissen verbleibt. PATENT CLAIM: Double ampoule according to patent 409 648, characterized in that the connecting capillary (b) is widened in its middle part (!) On the inside, but is tapered at the top and bottom to the extent that no liquid passes through after the lower taper (L) has been closed the upper taper (k) can pass through to the widening (i) , so that an air cushion remains in this.
