  • Flexible sterile closure system for a container with a side injection port
    Patent number: 4598834
    Abstract: A sealing cover (10) is disclosed for resealing a side injection port (14) on an IV solution container (12). Sealing cover (10) has a first end portion (28), a center portion (30) and a second end portion (32) which define a cover region (24). One side of the cover region (24) has an adhesive material (44) so that the cover can be adhesively secured to the port (14). A nonadhesive region (48) is positioned over the injectable membrane (20) of the port. The first and second end portions (28, 32) are folded relative to the center portion (30) and wrapped about the cylindrical portion (16) of the port (14) to enhance the adhesive attachment. Protrusions (36) on the center portion (30) can also be folded against the cylindrical portion for adhesive attachment. A pull tab region (26) extends from one of the end portions to permit removal of the cover.
