Abstract
A protector cap for establishing a sterile seal over a port having a puncturable section in a container wall and a cylindrical neck portion projecting from the periphery of the wall section. The cap comprises a molded housing having a ring-shaped recess for sealingly engaging the neck member and a chamber formed at least in part within a compressible handle portion. The handle portion is compressed prior to inserting the cap on the neck portion of the port and is subsequently released to establish a partial vacuum in the chamber. The partial vacuum assists in retaining the protector cap in position and prevents trapped air from forcing the cap off during subsequent heat-sterilization of the container.
