Device for transferring liquid from one container to another

摘要

The invention relates to a device for transferring liquid from a first container (7) which receives the liquid to a second container (6) which receives a substance to be dissolved, having a hollow body (1) for receiving a connection piece (7b) of the first container (7) in the region of a first hollow body aperture (1b) and of a second hollow body aperture (1a) which is arranged diametrically opposite the first one and is intended to receive a connecting piece (6a) of the second container (6) and at least one tubular needle (5) which is mounted in the hollow body (1) and is intended to perforate the sealing bungs (6b, 7b) which seal off the container connecting pieces in each case and are made of rubber or the like. The object of the invention is to produce a device of the aforementioned type which will make it possible, before the containers are punctured, to introduce one of the said containers into the hollow body, the intention also being to ensure that the containers can be punctured in a predefined sequence. A first solution provides for the tubular needle (5) to be arranged so as to be mounted in the hollow body (1) so as to be longitudinally displaceable towards a transferable stop (9, 10), the crossing resistance of which is greater than the resistance to penetration of the sealing bung (7b) of the first container (7) which can be inserted in the direction of displacement of the tubular needle (5), the tubular needle (5), after having overcome the crossing resistance, ... the sealing bung (6b) of the ... inserted in the hollow body (1) ...
