Abstract
Abstract A method of sterile packaging which involves the steps of partially filling a container with any of a number of antibacterial agents in liquid or semi-liquid form which contain iodine as the active ingredient, then sealing the container so that the air space is formed above the liquid within the container, and finally heating the container and its contents (which may include a solid object to be sterilized immersed or partially immersed in the liquid) to a temperature substantially below the boiling point of the liquid, and at a pressure of about one atmosphere, until the interior surfaces of the container above and below the liquid level, and the entire contents of such containers, are sterilized.
