Abstract: A lid for covering a beverage container. The lid includes a platform configured for engaging the container, and the platform includes retaining structure and a top surface with indicia associated therewith. An index member is retained generally on the top surface of the platform by the retaining structure, and the index member defines a window for viewing therethrough the indicia associated with the top surface of the platform. The index member is rotatable with respect to the top surface of the platform such that the window moves with respect to the indicia associated with the top surface of the platform. Both the platform and index member are configured to receive a straw generally in a center of the platform and index member. The index member includes stability-enhancing structure generally at a peripheral edge of the index member, and the stability-enhancing structure at least partially defines an edge of the window.
