ABSTRACT:
A device for stoppering and connecting a container containing a sterile liquid comprises a pair of hollow cup-like elements aligned coaxially and sealed together along their peripheries in a fluid-tight manner; a disk formed of a fluid-tight, pierceable elastomeric material located between the two hollow cup-like elements, the disk serving to seal the interior of the upstream cup-like element from becoming contaminated while permitting successive passages of materials therethrough, the upstream cup-like element having a hollow extension for connection to the container or to a tube coming from the container; and the downstream cup-like element having a closed extension with a weakened separation line between the extension and the downstream cup-like element whereby the extension may be broken under stress from the downstream cup-like element to provide access to the elastomeric disk.
