Provided is a novel container sterilization method in which no liquid agent is used. A container sterilization method is a method of performing sterilization by supplying a sterilization component to a container that is continuously conveyed along a predetermined conveyance path, the container sterilization method including supplying a humid ozone gas to a sterilization area, the humid ozone gas being an ozone gas that has humidity, the sterilization area being partitioned by a sterilization chamber that contains the conveyance path. The humidity of the humid ozone gas to be supplied to the sterilization region is regulated, depending on a temperature of the containers to be conveyed to the sterilization region.

Container sterilization method and container sterilization system

Provided is a novel container sterilization method in which no liquid agent is used. A container sterilization method is a method of performing sterilization by supplying a sterilization component to a container that is continuously conveyed along a predetermined conveyance path, the container sterilization method including supplying a humid ozone gas to a sterilization area, the humid ozone gas being an ozone gas that has humidity, the sterilization area being partitioned by a sterilization chamber that contains the conveyance path. It is preferable that the humid ozone gas to be supplied to the sterilization area have a higher temperature than the container to be conveyed to the sterilization area and the sterilization chamber have a higher temperature than the container to be conveyed to the sterilization area.

Provided is a sterilization device for a container which exhibits high sterilization performance while being low in cost. A heating medium is positioned in a sterilant passage so as to block the downstream end thereof in the direction in which the liquid sterilant is discharged. A ventilation passage is formed in the lateral surface of a tube body of a sterilant supply tube, on the upstream side in the direction in which the liquid sterilant is discharged in relation to the heating medium. A sterilant supply unit sterilizes the inner-peripheral surface of a container as a result of the sterilant vaporizing upon reaching the heating medium, leaking to the exterior via the ventilation passage formed in the lateral surface of the tube body, and adhering to the inner-peripheral surface of the container.
