Patent ID: 7070075

Claim:
A personal hydration system, comprising: a fluid reservoir, comprising: a body formed from a flexible waterproof material that defines an internal compartment adapted to receive at least 32 ounces of drink fluid, wherein the body includes two spaced-apart openings; a fill port associated with a first one of the openings, wherein the fill port includes a rigid neck that extends from the body, that defines a neck opening in fluid communication with the compartment and with a diameter of at least 3 inches, and that includes externally extending threads; an exit port associated with a second one of the openings and adapted to fluidly couple an elongate drink tube to the reservoir; a cap adapted to be releasably coupled to the neck of the fill port to selectively form a seal with the neck and prevent drink fluid from passing through the neck, wherein the cap includes internally extending threads that are adapted to sealingly engage with the externally extending threads of the neck to couple the cap to the neck, wherein the cap includes a plug portion that extends into the neck when the cap is sealingly coupled to the neck, and further wherein the cap includes a handle that extends at least partially into the plug portion and at least one recess that extends into the plug portion proximate the handle; a rigid support member extending around the neck and including an integral handle projecting away from the neck; an elongate, flexible drink tube adapted to receive drink fluid from the compartment of the reservoir, wherein the drink tube includes a first end region that is fluidly coupled to the second one of the openings and a second end region distal the first end region; and a self-sealing bite-actuated mouthpiece fluidly coupled to the second end region of the drink tube and adapted to selectively dispense drink fluid from the drink tube to a user, wherein the mouthpiece is selectively configured between a closed position, in which the mouthpiece is adapted to prevent drink fluid from being dispensed therethrough, and a dispensing position, in which the mouthpiece is adapted to permit drink fluid to be dispensed therethrough, wherein the mouthpiece is adapted to be configured from the closed position to the dispensing position responsive to compressive forces applied thereto, and further wherein the mouthpiece is biased to automatically return from the dispensing position to the closed position.
