Abstract: A protective cover for a beverage container, which cover is both removable and reusable. The cover is intended to prevent bees and other contaminating objects from entering the container after the container has been initially opened. The cover comprises a flexible, resilient disc having a notch formed therein, whereby the disc may be inserted to fit conveniently in the recessed area on the top of the beverage container and underneath the tab. The cover is rotated to align the notch with the opening in the container so that the liquid in the beverage container is accessible to the consumer. Similarly, the cover may be further rotated so that it covers the opening and thereby prevents the entry of foreign objects into the container.
