Abstract: A lid assembly that includes at least one curved linkage coupling a button to a spout. The spout has a drinking aperture and is configured to convey a liquid to the drinking aperture. The button is configured to slide linearly between button open and button closed positions. The at least one curved linkage is configured to rotate the spout when the button slides linearly. The at least one curved linkage is configured to rotate the spout into a spout open position when the button is slid linearly into the button open position. The at least one curved linkage is configured to rotate the spout into a spout closed position when the button is slid linearly into the button closed position. The liquid is drinkable by a user from the drinking aperture when the spout is in the spout open position.
