Abstract: The sterilization of open-topped containers is accomplished by vaporizing a sterilizing agent in the vicinity of the container. A conveyor for supporting containers to be sterilized brings the containers in proximity to a support means upon which are supported a heater element and a nozzle. The vertically moveable support means positions the heater element either in or immediately above the open top of the container. A sterilizing agent discharged from the nozzle impinges on the heater element and undergoes instantaneous thermal decomposition. The sterilizing agent condenses on the internal surfaces of the container.

Abstract: The sterilization of open-topped containers is accomplished by vaporizing a sterilizing agent in the vicinity of the container. The vaporization is preferably achieved by spraying the sterilizing agent on to a heating element positioned either in or immediately above the open top of the container.
