Backpack with magnetic hydration tube return

A hydration system for providing liquid to a user on demand, comprising:

• a backpack comprising a main body having a front side facing towards and adjacent to a user's back when the backpack is carried, a back side facing away from the user's back when the backpack is carried, and a pair of shoulder straps coupled to the main body and configured to extend over the user's shoulders and chest;
• a bladder disposed in the main body of the backpack configured to retain liquid, the bladder comprising a fill port for transferring liquid to and from the bladder and a discharge port for transferring liquid from the bladder;
• a hydration tube extending from the bladder through an opening in the main body and over the user's shoulder, wherein the hydration tube is configured to transfer liquid from a proximal end connected to the discharge port to a distal end;
• a valve disposed at the distal end of the hydration tube including an outlet configured to discharge liquid into the user's mouth;
• a first plurality of cylindrical magnets coupled to a shoulder strap of the pair of shoulder straps;
• and
• a second plurality of cylindrical magnets coupled to the hydration tube,
• wherein the first and second pluralities of cylindrical magnets are configured to connect by gravitational and magnetic forces when the hydration tube is released from the user's mouth and disconnect when the user exerts a force exceeding the magnetic force of the first and second pluralities of cylindrical magnets, and
• wherein upon release of the valve from the user's mouth the second plurality of cylindrical magnets sequentially connects by magnetic force to the first plurality of cylindrical magnets.

A hydration pack, comprising:

• a main body defining a storage compartment;
• a strap coupled to the main body;
• a bladder disposed in the storage compartment of the main body and configured to retain liquid;
• a hydration tube comprising a proximal end coupled to the bladder and a distal end;
• a valve disposed at the distal end of the hydration tube;
• a first longitudinal elongated metallic element disposed on the strap;
• and
• a second longitudinal elongated metallic element disposed on the hydration tube,
• wherein the first and second longitudinal elongated metallic elements are configured to connect by magnetic forces and disconnect by a force exceeding the magnetic force of the first and second longitudinal elongated metallic elements,
• wherein the second longitudinal elongated metallic element is disposed between the bladder and the valve,
• wherein the first longitudinal elongated metallic element is a first chain of magnets disposed end-to-end and the second longitudinal elongated metallic element is a second chain of magnets disposed end-to-end, and
• wherein the first chain of magnets is disposed within a first sleeve coupled to the strap and the second chain of magnets is disposed within a second sleeve coupled to the hydration tube.
