Abstract
A beverage can lid spout unit is provided with a closing lid movable between open and closed positions over a peripheral mounting part. A bellows part is secured within the mounting part and is biased to move outwardly when the lid is moved to an open position. When the lid is moved to a closed position, it compresses the bellows within confines of the mounting part to close-off the spout.
