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 value in communication with an outlet value in communication therewith, each of the values including a resilient flexible diaphragm member. 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 is secured to the diaphragm member thereof to ensure its sealing. A predetermined level of fluid pressure differential across each diaphragm member courses, respectively, the diaphragm members to concavely bend 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 sealinglingly abut their respective seats, thereby sealing the cup.
