  • Patent number: 4510621
    Abstract: A disposable, self-sealing pouch is disclosed which is readily adaptable for use for sterilization, sterility maintenance, disposal of contaminated items, and like medical applications. The pouch includes first and second coextensive pouch webs which are marginally joined together to define the interior of the pouch. The first pouch web defines a transversely extending access opening slit through which articles may be inserted into the pouch. In order to effect closing and sealing of the access opening slit, the pouch includes adhesive means provided on the first pouch web on opposite sides of the access opening slit. By this construction, the pouch may be easily and securely sealed by folding the pouch onto itself so that the adhesive means is brought into confronting relation with itself, thus forming an adhesive-to-adhesive of the access opening slit.
