Claim 0:
1. A container lid for use with a drinking container having one or more rigid sidewalls defining an interior chamber inside the drinking container, the drinking container being closed at a lower end and having an opening at an upper end, said container lid comprising:
a cap member structured and arranged to attach to the drinking container at the opening thereof to close the interior chamber, said cap member having a coupling aperture therethrough;
a male insert having a flow path connecting an upper end and a lower end thereof, said upper end of said male insert attached to or integral with a hydration tube, said male insert having a sealing device associated with a downwardly extending sealing section at said lower end of said male insert and
a female coupling disposed in said coupling aperture of said cap member, said female coupling having an upwardly facing receptacle at an upper end thereof, said receptacle sized and configured to removably receive said lower end and said sealing section of said male insert and to sealably engage said sealing device of said male insert when said lower end and said sealing section of said male insert is received in said receptacle, a lower end of said female coupling attached to or integral with an internal straw that extends downward in the interior chamber of the drinking container, said female coupling further comprising a flow path that interconnects said lower end and said upper end thereof, said cap member and said female coupling being structured and arranged to open said flow path of said female coupling to said internal straw and the interior chamber of the drinking container only when said sealing section of said male insert is received in said receptacle and suction is applied to said upper end of said female coupling from the hydration tube and through said flow path of said male insert and to close said flow path through said female coupling when suction is removed from the hydration tube and to prevent leakage from the interior chamber of the drinking container through said flow path of said female coupling when the hydration tube is removed from said container lid which causes said male insert to be removed from said receptacle.
