Abstract

This invention comprises a sanitary beverage can lid wherein the center platform of the lid including the pull tab is raised from below the rim of the can as in conventional cans to a position close to or slightly above the rim of the can. The center platform diameter is reduced in diameter to provide additional space from the exterior of the can body to the edge of the platform. The pull tab is positioned in the middle of the center platform so that the end of the pull tab is at the edge of the center platform to facilitate opening of the can. The raised center platform and the lid design prevent an individual's lip from coming in contact with the groove along the edge of the lid where dirt may accumulate. Another feature is the provision of a raised rim on the platform with an interior drain-back slope so that any excess beverage flows back into the can.
