Abstract
A lid assembly for a drink container includes a cap, a wall and a valve member. The cap fits onto a drink container and includes a spout defining a drink passage and a vent opening offset from the drink passage. The wall depends downwardly from a lower surface of the cap and surrounds the drink passage and the vent opening. The valve member is selectively receivable within a cavity defined by the wall. With the valve member received in the cavity and the cap fit onto the drink container, a first seal isolates the vent opening from the drink passage, a second seal is movable with respect to the wall and selectively contacts the wall to selectively isolate the vent opening from liquid in the drink container, and a third seal selectively isolates the drink passage from liquid in the drink container.
