1. A method for sterilizing a lid and thereafter providing said lid on top of a container, the container having been previously sterilized, in a non-germ atmosphere, the method comprising:
- intermittently rotating a rotary drum such that it moves to successive stop positions, the rotary drum having a plurality of rooms, each of which has an opening that intermittently and airtightly faces an inner surface of a wall cylinder having at least one mouth,and, through each mouth of said wall cylinder, (a) providing a lid into one of said rooms, (b) applying a sterilizer and ultraviolet rays into the room to sterilize said lid and (c) blowing hot wind into the room to dry said lid, each of steps (a) - (c) being performed in order at different stop positions.

3. A lid sterilization means comprising an outer cylinder which seals both sides of a cylindrically shaped wall cylinder,
and a rotary drum which comprises a number of concave shaped rooms at fixed positions on an outer surface of said rotary drum, each room airtightly facing an inner surface of said wall cylinder, the rotary drum being installed in said outer cylinder to intermittently rotate by fixed angular amounts between stop positions, said wall cylinder having, at portions adjacent where said rooms intermittently stop, with a carry-in mouth through which said lid is carried into said room, a sterilizer apply mouth to apply sterilizer means therethrough, an ultraviolet rays apply mouth to apply ultraviolet rays therethrough, a hot wind passage mouth for blowing hot wind therethrough and a carry-out mouth to carry out said lid therethrough.
