ABSTRACT:
A twin-chamber syringe for medical purposes has a cylindrical syringe body with a conical shoulder on the front end, a peripheral rotating locking ring for firmly mounting a sealing cap or subsequently a tube, a piston that can be displaced by means of a plunger and which seals the syringe body at the rear, and a separate container to be connected to the syringe, as the second chamber, and which has a sealing cap with a flanged cap incorporated in it. The improvement is that the container serving as the second container, and which contains the mixing component, has a resilient locking cap with a central weak point diaphragm, and that the flanged cap has a centering device covering that weak point and receiving the conical shoulder, so that when the container is fitted, the centering device and the peripheral locking ring snap into each other and can be later detached.
