Claim 14:
15. A liquid drinking system, comprising:
a drinking container having one or more rigid sidewalls defining an interior chamber, said drinking container being closed at a lower end thereof and having an opening at an upper end thereof;
a container lid having a cap member structured and arranged to attach said container lid to said drinking container at said opening thereof to close said interior chamber of said drinking container, said cap member having a coupling aperture therethrough;
an elongated hydration tube having a first end and a second end;
a male insert having an upper end and a lower end, said upper end of said male insert attached to or integral with said first end of said hydration tube, said male insert having a sealing device associated with a downwardly extending sealing section at said lower end thereof, said male insert having a flow path connecting said upper end and said lower end thereof;
an elongated internal straw having a first end and a second end; 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 sealing section of said male insert and 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 being sized and configured to be attached to or integral with said second end of said internal straw so as to extend said internal straw downward in said interior chamber of said drinking container, said female coupling further comprising a flow path interconnecting 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.
