ABSTRACT:
A method and apparatus to temporarily cover an opening of a container to prevent the entry of foreign matters during a process in which a large number of containers are handled. A temporary cover has a sticky surface on one side that is large enough to cover the opening of the container. The temporary cover is positioned near the opening of the container, with the sticky surface directed to face the opening. Then, the temporary cover is lightly pressed against the end of the opening so that the cover adheres in position. After a given operation has been completed, the temporary cover is removed from the opening of the container.
