Hydration delivery tube system

A personal hydration system comprising:

• 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 a majority of the length of the delivery tube in a retracted position, wherein the delivery tube can be pulled to an extended position wherein at least a portion of said length of the delivery tube extends outwardly from the enclosure;
• and
• a resilient retraction member comprising an elastic cord having first and second end portions, the first end portion of the cord being connected to the distal end portion of the delivery tube, the cord having a portion that extends along the length of the delivery tube, the cord having another portion including the second end portion of the cord that extends away from the delivery tube at a location intermediate the first and second end portions of the delivery tube, the second end portion of the cord 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 cord applies a pulling force on the delivery tube that causes a portion of the delivery tube to form a coil in the enclosure when the delivery tube is retracted.

• 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;
• a flexible sheath covering a portion of the delivery tube;
• an enclosure coupled to the reservoir and sized to house a majority of the length of the delivery tube and the sheath in a retracted position, wherein the delivery tube and the sheath can be pulled to an extended position wherein at least a portion of said length of the delivery tube and the sheath extend outwardly from the enclosure;
• and
• a resilient retraction member comprising an elastic cord having first and second end portions, the first end portion of the cord being connected to the distal end portion of the delivery tube, the cord having a portion that extends through the sheath, the sheath maintaining said portion of the cord in a position extending along the length of the delivery tube, the cord having another portion including the second end portion of the cord that extends outwardly from the sheath at a location intermediate the first and second end portions of the delivery tube, the second end portion of the cord being connected at a fixed location relative to the enclosure such that when the delivery tube and sheath are pulled outwardly to the extended position and then released by the user, the cord applies a pulling force on the delivery tube and sheath that causes a portion of the delivery tube to form a coil in the enclosure when the delivery tube is retracted.
