ABSTRACT:
The present invention provides methods and means for lid sterilization and temporal sealing. With the lid sterilization means, a lid's whole surface is completely sterilized, while it is held and revolved, and the lid then is put on the opening of a container which is hung by a flange on a pair of rails and carried by a pushing plate. With the temporal sealing means, the lid is partially pushed on the flange by a heater and is briefly and temporarily sealed.
