A spill resistant lid assembly (10) is provided for closing the open top (12) of a drink container (14). The lid assembly (10) includes a spout housing (16), a valve plate (18), a resilient valve seal (20), and an attachment cover (22). The valve seal (20) includes an inlet diaphragm (96) and an outlet diaphragm (104) that cooperate with a pair of valve posts (46,72) to resist leakage of a beverage from the drink container (12) while allowing a flow of beverage from the drink container (14) when a user applies suction to an outlet port (42).
