Abstract: A beverage container has a base releasably attached to a vessel. A reciprocating nipple is mounted on the base. A flexible conduit mounted at the base is connected to the nipple. The flexible conduit can communicate between the vessel and the nipple. A user can draw liquid from the vessel through the flexible conduit and nipple. An actuating element is mounted on the base and is coupled to the nipple. The actuating element is manually operable to reciprocate the nipple between an extended and a retracted position. Portions of the flexible conduit are adapted to collapse, occlude, and prevent communication of liquid to the nipple in response to motion of the nipple into the retracted position.
