    • 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.
    • 一种用于在容器壁上具有可刺破部分的端口上建立无菌密封件的保护帽和从壁部分的周边伸出的圆柱形颈部。 所述盖包括模制外壳,所述模制外壳具有用于密封地接合所述颈部构件的环形凹部和至少部分地形成在可压缩手柄部分内的腔室。 在将盖子插入端口的颈部部分之前,手柄部分被压缩并随后被释放以在腔室中建立部分真空。 部分真空有助于将保护器盖保持在适当位置,并且在随后的容器加热灭菌期间防止被捕获的空气迫使盖关闭。
