The cover has a portion which fits inside the container and is provided with a flexible sealing member which extends radially beyond the edge of the cover. The flexible member becomes deflected upon insertion into the container and frictionally engages the inside wall surface of the container. An opening is provided in the cover for permitting air to flow into and out of the container.
