ABSTRACT:
A sealed flexible container is disclosed with a sterile, openable seal member formed by inserting part of a thermoplastic tube between a seal in such a manner as to permit the tube to communicate across the seal. The outer end of the tube may be enclosed with a thermoplastic pocket member having open inner and outer ends. Tear means are provided on the pocket members to permit the pocket members to be manually torn, exposing the tubes. The tear means are further defined by a rupturable seal line which has an outwardly-pointing apex, facilitating the rupturing of said tear means and opening of the pocket member. A puncturable diaphragm at the inner end of the tube is also provided to preserve the sterility of the system.
