Abstract: Hydration systems with improved fluid reservoirs. An elongate drinking tube extends from the reservoir and includes a distal end upon which a mouthpiece may be mounted. In some embodiments, the mouthpiece is a self-sealing mouthpiece. The reservoir includes a fill port, through which drink fluid may be added to the reservoir, and a closure member in the form of a cap for selectively sealing the fill port. In some embodiments, the reservoir includes a support member that extends around the fill port, including a handle that projects generally away from the fill port, and is adapted to provide a counter lever to assist in opening and closing of the fill port and/or to position the reservoir for filling. In some embodiments, the hydration system includes a pack into which the reservoir is received.

Abstract: Hydration systems with improved fluid reservoirs. The reservoirs include a fill port with a neck having an opening through which drink fluid may be inserted into the reservoir's internal compartment. The hydration systems also include a drink tube through which a user may draw drink fluid from the reservoir. The hydration systems further include a cap that selectively seals the opening. In some embodiments, the opening has a diameter of at least 2.5 inches. In some embodiments, the opening has a diameter of at least 3 inches. In some embodiments, the cap is threaded onto the neck. In some embodiments, the hydration systems include wrench assemblies and/or support members that extend around the neck and which may be selectively used to assist in sealing or unsealing of the cap onto the opening and/or to position the reservoir.

Abstract: A hydration system with an improved fluid reservoir. A drinking tube extends from an outlet port of the reservoir and includes a distal end upon which a mouthpiece may be mounted. In some embodiments, the reservoir includes a relatively large-diameter fill port. In some embodiments, the reservoir includes a closure member with a handle for selectively sealing the input port. In some embodiments, the reservoir includes a wrench assembly that enables the user to more easily open and close the input port and/or to position the reservoir for filling. In some embodiments, the hydration system includes a pack into which the reservoir is received, and in some embodiments, the pack includes a hanger assembly adapted to support the reservoir within the pack.

Abstract: Personal hydration systems that are at least partially, if not completely, formed from chemically resistant materials and/or which include at least one quick-connect assembly. The hydration system includes a fluid reservoir and may be housed within a pack. Drink fluid is drawn from the reservoir through a drink tube to a mouthpiece. In some embodiments, the hydration system includes a manually actuated on/off valve, a filter, a pump, and/or a bite-actuated mouthpiece. The quick-connect assembly fluidly interconnects components of the hydration system and is configured to quickly release, and permit reattachment of, the detached components or replacement components, which may enable different performance from the detached components. In some embodiments, at least a portion, if not the entire, hydration system is formed from at least one chemically resistant material. In some embodiments, the reservoir is formed from a heat-sealable and/or multilaminate material.

Abstract: Quick-connect assemblies and hydration systems incorporating the same. The hydration system includes a fluid reservoir and may be housed within a pack. Drink fluid is drawn from the reservoir through a drink tube to a mouthpiece. In some embodiments, the drink tube is connected to the reservoir at an exit port, the hydration system includes a manually actuated on/off valve, a filter, a pump, and/or a bite-actuated mouthpiece. The quick-connect assembly fluidly interconnects components of the hydration system and is configured to quickly release, and permit reattachment of, the detached components or replacement components. In some embodiments, the replacement components enable different performance from the detached components. In some embodiments, the quick-connect assembly is adapted to selectively couple a bite-actuated mouthpiece and a gas mask adapter to the drink tube. In some embodiments, at least a portion, if not the entire, hydration system is formed from a chemically resistant material.

Abstract: A personal hydration system with component connectivity. The hydration system includes a fluid reservoir that may be housed within a pack. Drink fluid is drawn from the reservoir through a drink tube in fluid communication with the reservoir at one end and with a mouthpiece at the other. In some embodiments, the hydration system includes a manually actuated on/off valve downstream from the reservoir and/or a bite-actuated mouthpiece. The hydration system further includes a quick-connect assembly that fluidly interconnects components of the hydration system and which is configured to quickly release, and permit reattachment of, the detached or replacement components. In some embodiments, the hydration system includes a quick-connect assembly that is adapted to selectively couple a bite-actuated mouthpiece and a gas mask adapter to the hydration system's drink tube. In some embodiments, at least a portion, if not the entire, hydration system is formed from a chemically resistant material.

Abstract: A personal hydration system with a flow-restricting device. The hydration system includes a fluid reservoir configured to store fluid and a tube assembly that is coupled to the reservoir and configured to deliver fluid to a user's mouth, such as via a mouthpiece. The system further includes a flow-restricting device that is configured to selectively restrict the flow of drink fluid between the reservoir and the mouthpiece. In some embodiments, the flow-restricting device includes a body and a rotatable core.

Abstract: A personal hydration system with an improved mouthpiece for use in providing fluid for delivery to a user. The mouthpiece includes a neck that is adapted to be mounted on a supply tube to a hydration system and which is joined to a resilient head. The head includes a dispensing face with a pair of lips that define a normally closed slit, through which fluid is dispensed from the mouthpiece, a perimeter and a minimum dimension between opposed points on the perimeter. The bite region extends from the perimeter to a shoulder, which joins the bite region and the neck. From a closed position, in which the lips extend against each other to close the slit and prevent fluid from being dispensed through the slit, the mouthpiece is deformable to a dispensing position in which the lips are spread at least partially away from each other to allow fluid to be dispensed through the lips.
