Abstract

Open-topped containers are sterilized by employing an electrostatic field to insure complete coating of the interior surface of such containers with a sterilizing agent. The sterilizing agent is supplied in liquid form, ultrasonically atomized, the thus formed droplets entrained in a stream of carrier gas and an electrical charge imparted to the entrained droplets so that they will be influenced by the electrostatic field created in the containers.
