Abstract
A beverage container is disclosed with a cap body having an upper straw with an incorporated valve that moves upward and downward to toggle between an open and closed position and a lower straw that is stationary within the cap body. Hermetic seals are formed between the straw bodies and cap body that allow the proper operation of a straw that opens, allowing fluid to flow through the straw bodies, and closes, stopping the flow of fluid through the straw bodies.
