A method for sterilizing a container is provided where a penetrable septum of a sealed empty device is penetrated with an injection member. A fluid sterilant is then injected through the injection member and into an interior chamber of the device. The fluid sterilant is allowed to reside within the chamber a sufficient amount of time to render the chamber either sterile or bactericidal. Product can then be introduced through the septum into the sterile or bactericidal chamber. The resulting penetration aperture is then resealed to hermetically seal the product within the chamber.
