A self-sealing drinking container includes a cup body having a hollow interior for holding and dispensing a liquid, and a lid assembly which fits sealingly on the cup body. The lid assembly has an inlet passage with an inlet valve in communication therewith, and an outlet passage with an outlet valve in communication therewith, each of the valves including a resiliently flexible diaphragm member. In a preferred embodiment, each of the inlet and outlet valves includes a cage having an open top and an open bottom to allow fluid passage therethrough, the cage having a seat formed therein for receiving a diaphragm member. The diaphragm member is located seatably into the seat so as to selectively seal thereagainst and thereby prevent fluid flow therepast. A locator post in each cage centrally abuts the diaphragm member thereof to ensure its seating. A predetermined level of fluid pressure differential across each diaphragm member causes, respectively, the diaphragm members to concavely bend (or flex) away from their respective seat and thereby allow fluid flow through the valves. However, below the respective predetermined levels of fluid pressure differential, the diaphragm members sealingly abut their respective seats, thereby sealing the cup.
