A rotatable circular beverage can rim cover having an up-standing loop-shaped outer periphery configured to receive and snap over a raised circular edge of a beverage can. The protective cover serves two main purposes. It is intended to provide a sanitary covering means and to prevent contaminating objects from entering the can after opening. The cover has a circular depressed planar area that has a detachable pull-ring segment assembly covering the punch key portion of a beverage can. Upon the removal of the section by pulling and removing the pull-ring assembly, the protective cover creates an opening through which the contents of the beverage container can be consumed. The remaining section of the protective cover can be rotated between an opened or closed position to all consumption of the soft drink when in an opened position, and to cover the container's opening to prevent insects and other contaminants from penetrating the beverage can when in the closed position. The protective cover also provides an inclining hill-shaped projection to assist in lifting the underside of the punch key to an altitude that allows operator to safely lift the punch key in opening process.
