Rigid metal reservoir hydration system
First Claim
Patent Images
1. A back-mounted hydration system comprisinga rigid metal reservoir;
- an inlet;
an outlet;
a check valve assembly which allows air to enter the reservoir as liquid exits;
a flexible drinking tube;
wherein the flexible drinking tube comprises flexible copper tubing having a first end and a second end, the first end being affixed to a fitting at the outlet at the bottom end of the reservoir, and the second end being affixed to a valve, which may be operated by a user'"'"'s mouth via biting pressure, whereby the liquid may be delivered to the user'"'"'s mouth for drinking on demand and at the will of the user;
and wherein the flexible drinking tube may be flexed and bent by the user into a position or orientation and stays in that position or orientation after the user relinquishes deliberate contact with and is finished adjusting the drinking tube;
wherein the flexible copper tubing is surrounded by a sheath comprised of carbon fiber, which is glued, epoxied, or otherwise permanently adhered to the copper tubing, that will allow the copper tubing to bend, but will restrict the bending radius enough so that the copper tubing will not become creased or crimped.

Abstract
Provided is a novel hydration system which incorporates a rigid, low-profile, contoured reservoir made of stainless steel or another suitable non-plastic material that replaces typical plastic water bladders and a flexible metal drinking hose in backpack-mounted hydration systems. The rigid metal reservoir hydration system solves several problems and health concerns associated with plastic hydration systems.

4. A back-mounted hydration system comprising
a rigid metal reservoir; -
an inlet; an outlet; a check valve assembly which allows air to enter the reservoir as liquid exits; a flexible drinking tube; wherein the reservoir is surrounded by a sheath comprised of carbon fiber, which is glued, epoxied, or otherwise permanently adhered to the reservoir wall, that will allow the outer walls of the reservoir to be made thinner to reduce the weight of the reservoir, while maintaining adequate strength for the intended use.

5. A method for manufacturing a hydration system comprising
a rigid metal reservoir; -
an inlet; an outlet; a check valve assembly which allows air to enter the reservoir as liquid exits; a flexible drinking tube; and a bite valve, comprising the steps of; pressing together the contact face of a top tool and a metal sheet along a bottom mold area to thereby retain the sheet in position; sealing the sheet area that is subjected to the working fluid solely by contact between the contact face of the top tool and the metal sheet; and hydraulically pressure forming the sheet against the bottom mold area using a pressurized medium from a pressure generating unit.

6. A method for manufacturing a hydration system comprising
a rigid metal reservoir; -
an inlet; an outlet; a check valve assembly which allows air to enter the reservoir as liquid exits; a flexible drinking tube; and a bite valve, wherein the inlet comprises; a lid receiver; and a lid; wherein the lid receiver is affixed within an opening in the metal reservoir and the lid may be secured and removed from the lid receiver by a user, comprising the steps of; pressing together the contact face of a top tool and a metal sheet along a bottom mold area to thereby retain the sheet in position; sealing the sheet area that is subjected to the working fluid solely by contact between the contact face of the top tool and the metal sheet; and
hydraulically pressure forming the sheet against the bottom mold area using a pressurized medium from a pressure generating unit.

7. A method for manufacturing a hydration system comprising
a rigid metal reservoir; -
an inlet; an outlet; a check valve assembly which allows air to enter the reservoir as liquid exits; a flexible drinking tube; and a bite valve, comprising the steps of; providing a molding tool having a first mold and a second mold with each of the first and second molds forming an internal mold cavity when placed adjacent one another, securing a metal tubular member having end portions to a fluid delivery system, placing the metal tubular member in the first mold of the molding tool such that the end portions of the metal tubular protrude out of an upper and lower access portion of the first mold, placing the second mold against the first mold to sealingly engage the metal tubular member; heating the metal tubular member to a temperature of between about 1,100°
F.-2,000°
F.;injecting a fluid under pressure into the metal tubular member to cause the metal tubular member disposed within the internal mold cavity to expand and conform to the internal mold cavity; separating the first and second portions of the molding tool and removing the metal tubular member from the internal mold cavity, cutting the metal tubular member to obtain a reservoir having the shape of the internal mold cavity. - View Dependent Claims (9)
