An injection port for injecting fluid through a needle into the contents of a container. The port has a covering film securing a sterile pad of resealabie material to a base member 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. The base member may be a container wall, a tube communicating with the container interior, a mounting film providing a modular port, or a protector fim preventing contact hetween the pad and the bag contents. The cover may have a pull tab for removal of the pad. The modular port may be held in position by a pressure sensitive adhesive. A method for making the port is described. |
