ABSTRACT:
A transfer device for use in mixing substances in different containers normally closed by a stopper of resilient material having a puncturable diaphragm consisting of a central body portion and a pair of aligned spikes or cannulas projecting from opposite sides of said central body portion. Each of the cannulas terminates in a tip portion remote from the central body portion and there are at least one pair of transfer passages extending through the cannulas, the opening at one tip portion of one of the transfer passages is of smaller cross section than the opening of said transfer passage at the tip of the other cannula. The other transfer passage is the reverse of the first transfer passage; that is, the cross sectional relationships of the openings at the tips are the opposite of the first transfer passage. Thus in use the cannulas are inserted through the stopper in a pair of containers to transfer contents, usually fluid, from one container to the other, and the specific arrangement of the transfer passages facilitates smooth flow through the transfer device, one being a fluid passage, the other an air venting passage. The invention also includes the combination of a transfer device, an outer cover member including means for supporting the transfer device therein and a detachable closure member overlying and normally sealing the opening in the outer cover member.
