A storage receptacle sealing and transfer apparatus is disclosed for selectively enabling sealing and transfer of material to and from the receptacle. The apparatus is particularly useful for maintaining and later transferring drug and associated materials, under sterile conditions, to achieve mixing, as, is necessary, for example, in reconstituting a drug by mixing the drug with a diluent prior to delivery to a patient. The transfer apparatus is mounted at the aperture, or mouth, of a storage receptacle to seal the aperture until the contents are needed, and then to permit sterile transfer from one receptacle to another receptacle through a central passage. The apparatus also includes venting through one or more passages offset from the central passage for supplying or discharging air into the storage receptacle as needed, and a filter is included in each vent passage, with the filter being permeable to passage of gases, including air, in either direction through the vent passage, but precluding passage of liquid or solid materials or microorganisms in either direction through the vent passage. The central passage and all venting passages are sealed until use, and the central passage also includes a septum in one disclosed embodiment, with a penetrating unit being included for access through the septum to the interior of the storage receptacle for delivery or withdrawal of substance therefrom.

A sealing and transfer apparatus for selectively sealing a substance within a storage reservoir of a storage receptacle and transferring the stored substance from the storage reservoir through an outlet opening from said reservoir, said apparatus comprising: a body portion having a central bore therein, said central bore having inner and outer ends, at least said outer end having a septum positioned thereacross adapted to engage a portion of a unit having an opening therein for receiving said substance when transferred from said storage receptacle; mounting means at one part of said body portion for enabling said transfer apparatus to be sealably mounted at said outlet opening of said storage receptacle; and a venting conduit extending through said body portion and having first and second chambers therein, said first chamber being defined by inner and outer annular ridges, said venting conduit also having an inner port communicating with said storage reservoir when the transfer apparatus is mounted on said storage receptacle at said oulet opening thereof, and an outer port opening externally of said transfer apparatus, said venting conduit having a one-piece micropore hydrophobic filter therein between said first and second chambers so that one part of each of said ridges is in contact with said filter, said filter allowing passage of gas therethrough in either direction but precluding passage of liquid or solid materials therethrough in either direction independent of the relative positions of said storage receptacle and said venting conduit and with said venting conduit thereby requiring no check valve positioned therein.
