Abstract: A lid for a beverage container includes a lid housing with a drink opening, a slider member, and a seal assembly. The seal assembly has a seal arm, a seal and a spring. The slider member slides linearly about the lid housing. A cam pivotally connected to the slider member engages the seal arm. The slider member and cam operate to move the seal arm from an open position to a sealed position. The drink opening is open when the seal arm is in the open position, and the drink opening is closed by the seal when the seal arm is in the closed position.
