The lid (10) includes a housing (14) to mount the lid (10) to the beverage container, a manually actuated valve stem (16) mounted to the housing (14) to translate relative to the housing (14), a drinking port (18) extending through the housing (14), a drinking valve head (20) carried on the stem (16) for movement relative to the housing (14) between a closed position closing the drinking port (18) and an open position wherein the beverage can flow through the drinking port (18), a pressure relief port (22) extending through the drinking valve head (20) to allow equalization of pressure across the head 20 with the head 20 in the closed position, and a pressure relief valve head (24) mounted to the stem 16 for movement relative to the drinking valve head (20) between a closed position closing the pressure relief port (22) and an open position wherein air can pass through the pressure relief port (22). The pressure relief valve head (24) is releasably mounted to the stem (16) by a connector (26). A resilient member (28) is sandwiched between the stem (16) and the drinking valve head (20) to transmit an actuating force from the stem (16) to the drinking valve head (20) and to allow the stem (16) and the pressure relief valve head (24) to translate relative to the drinking valve head (20).
