  • Patent number: 4632673
    Abstract: A pierceable port for injecting or withdrawing a fluid through a hollow needle inserted into a container. The port has a covering film securing a sterile pad of resealable material to a wall of the container having a portion pierceable by a needle. A tear strip is heat welded to the cover so as to form a removable tab comprised of a welded tear strip section, a welded cover section and an unwelded lap forming a grip for removing the tab. The tab is connected to an unwelded portion of the cover by a tear joint of substantially less tear strength than either the tab or the unwelded cover portion. The cover and the base member define a chamber for maintaining the sterility of the pad until the tab is removed to expose a sterile portion of the pad for insertion of the needle. A method for making the port is described.
