Patent ID: 7063243

Claim:
A personal hydration system, comprising: a flexible reservoir adapted to be received into a body-mountable pack and having a body portion with an internal compartment adapted to receive drink fluid, wherein the reservoir includes an exit port and a fill port, and further wherein the fill port includes a neck having an opening through which drink fluid may be added to and removed from the compartment; a removable cap adapted to selectively seal the opening of the neck; a wrench assembly extending around the neck, wherein the wrench assembly includes a handle projecting generally away from the neck, wherein the cap is adapted to be removed from the neck by rotation of the cap in a first direction, and further wherein the wrench assembly is coupled to the neck such that the wrench assembly is retained against rotation relative to the neck, thereby providing a counter lever to assist in the removal of the cap from the neck and the attachment of the cap onto the neck to form a seal therewith; an elongate drink tube coupled to the exit port of the reservoir and adapted to receive drink fluid therefrom; and a self-sealing mouthpiece 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.
