A transfer set for transferring fluid, including drugs, vaccines, medicaments, solutions and the like, between a first container, such as a conventional vial, and a second container, such as a conventional syringe having a unique multipurpose resealable member. The transfer set assembly includes an elastomeric tubular fluid transfer and resealable valve member preferably including an open end mounted on the pierceable closure or stopper of a vial and a generally closed distal end having a longitudinal slit and a piercing member is telescopically received within the fluid transfer valve member having a piercing end opposite the pierceable closure. The fluid transfer valve member is preferably formed of silicone and is surrounded by a generally tubular luer connector member having an open end mounted on the pierceable closure and a distal end having male luer threads. This assembly is enclosed within a cup-shaped closure and the assembly is retained to the first container or vial by a collar preferably secured to the vial by crimping. Upon removal of the cup-shaped closure, fluid communication between the vial and a second container, such as a syringe, is achieved by threading the luer connector of the syringe on the luer threads of the tubular luer connector member, which drives the tip through the slit of the elastomeric fluid transfer valve member against the distal end of the piercing member, driving the piercing end through the pierceable closure. In the preferred embodiment, the piercing member includes a generally longitudinal channel which establishes communication between the vial and the syringe through the tubular fluid transfer valve member.

1. A resealable transfer set for transferring fluid between a first container having an opening sealed with a pierceable closure and a second container, said transfer set comprising: a generally tubular elastomeric fluid transfer valve member mounted on said first container having an open end portion generally coaxially aligned with said opening of said first container and a generally closed portion spaced from said open end portion having a longitudinal slit therethrough, said longitudinal slit being biased to a closed position, and a piercing member telescopically received within said fluid transfer valve member between said open end portion and said generally closed portion generally coaxially aligned with said first container opening, said piercing member having a first relatively sharp piercing end portion opposite said pierceable closure and a second distal end portion opposite said generally closed portion of said transfer valve member, whereby a generally tubular portion of said second container may be driven through said slit in said generally closed portion of said fluid transfer valve member against said second distal end portion of said piercing member, driving said first piercing end portion of said piercing member through said pierceable closure and establishing fluid communication between said first and second containers, wherein said generally tubular elastomeric fluid transfer valve member includes an outwardly tapered tubular portion adjacent said generally closed portion and said piercing member second distal end portion is enlarged to be closely received in said outwardly tapered tubular portion of said fluid transfer valve member releasably retaining said piercing member in said fluid transfer valve member, wherein said transfer set includes a generally tubular luer connector member surrounding said fluid transfer valve member having a lateral opening adjacent said outwardly tapered tubular portion of said elastomeric fluid transfer valve member, permitting said outwardly tapered tubular portion to expand laterally and release said distal end portion of said piercing member.2. The resealable transfer set defined in claim 1, wherein said piercing member includes a generally longitudinally extending external channel establishing fluid communication between said first and second containers through said fluid transfer valve member.3. The resealable transfer set defined in claim 1, wherein said generally tubular luer connector member generally surrounding said fluid transfer valve member has a first proximate open end portion mounted on said first container and said lateral opening of said generally tubular luer connector, member having a luer threaded portion.4. The resealable transfer set defined in claim 3, wherein said generally closed portion of said fluid transfer valve member includes a generally radial annular lip portion overlying a distal end portion of said generally tubular luer connector member retaining and supporting a distal end of said fluid transfer valve member on said first container.5. The resealable transfer set defined in claim 3, wherein said transfer set includes a cup-shaped closure surrounding said generally tubular luer connector member having an open end mounted on said first container and a closed distal end.6. The resealable transfer set defined in claim 1, wherein said transfer set includes a cup-shaped closure surrounding said fluid transfer valve member having an open end mounted on said first container and a closed distal end.7. The resealable transfer set defined in claim 6, wherein said transfer set includes a collar having a first proximate tubular portion surrounding said open end portion of said fluid transfer valve member mounting said fluid transfer set on said first container and a second distal tubular portion surrounding a portion of said cup-shaped closure adjacent said open end of said closure.8. The resealable transfer set defined in claim 7, wherein said closure includes a frangible portion surrounded by said second distal tubular portion of said collar.
