The top member has a top forming portion adapted for overlying the open end of the container. An integral skirt depends from adjacent a peripheral edge of the top forming portion and is adapted to engage the rim of a container to form a seal therebetween. The skirt has lock means for releasably retaining the top forming portion in covering relation to the open end of the container. The tubular ring is mounted on the top member coaxial with and in engagement with the exterior surface of the skirt. The ring is made as a part separate from the lid and is mounted thereon when desired. The ring can have advertising indicia printed thereon and can also be used to display printed information relating to the container and/or the product contained in the container on which the closure is used.
