Patent ID: 7464837

Claim:
A personal hydration system comprising: a fluid reservoir configured to contain a fluid; a delivery tube having a first end portion and a second, distal end portion, the first end portion being fluidly connected to the fluid reservoir to allow fluid contained in the reservoir to flow outwardly through the delivery tube to a user's mouth; an enclosure coupled to the reservoir and sized to house at least a portion of the delivery tube in a retracted position, wherein the delivery tube can be pulled to an extended position wherein a length of said portion of the delivery tube extends from the enclosure; a resilient retraction member having first and second end portions, the first end portion of the retraction member being connected to the distal end portion of the delivery tube and the second end portion of the retraction member being connected at a fixed location relative to the enclosure such that when the delivery tube is pulled outwardly to the extended position and then released by the user, the retraction member applies a pulling force on the delivery tube that pulls the delivery tube back toward the retracted position; and a flexible sheath, wherein a portion of the delivery tube and a portion of the retraction member are housed within the flexible sheath, the sheath maintaining said portion of the retraction member in a position extending along the length of said portion of the delivery tube housed within the flexible sheath.
