A hydration system includes a liquid reservoir, a bottleneck plug, a tube, a hydration valve (e.g., bite valve), and a flow-restricting device (e.g., check valve). The tube comprises a first end for coupling to the liquid reservoir via the plug, a second end having the hydration valve, and the flow-restricting device interposed between the liquid reservoir and the hydration valve. The plug may be inserted into a variety of bottlenecks.

Disclosed are flexible fluid reservoirs including a front sheet and a back sheet, each comprising a four-layer insulated wall. The four-layer insulated wall includes an interior layer and an exterior layer, and a metallic film layer and an insulation layer disposed between the interior layer and the exterior layer where the metallic film layer is oriented toward the exterior layer and the insulation layer is oriented toward the interior layer. One or more of the interior or exterior layers can be a metallocene modified polyethylene film. The metallic film layer can be aluminum coated polyethylene terephthalate resin. The insulation layer can be a foam layer comprising closed cell polyethylene resin. The four-layer insulated wall can resist or limit temperature changes of a fluid disposed within the reservoir for a period of time. The insulated fluid reservoirs can include closure mechanisms for sealing an upper opening of the reservoir.

An apparatus for facilitating carrying and consuming of liquid by a user. The apparatus includes a container comprising a neck portion, a body portion, and a securing portion. The body portion includes an exterior wall defining an interior space. The neck portion includes an opening leading into the interior space. The body portion stores a liquid in the interior space. The neck portion allows retrievably transferring of the liquid in the interior space through the opening for facilitating the consuming of the liquid by the user. The securing portion is attached to an apparel wearable by the user, for movably securing the container to the apparel for facilitating the carrying of the liquid in the container. The container is removably disposable between at least one of two layers of a portion of the apparel, and a layer of the portion of the apparel and a skin surface of the user.

The systems and processes described herein correspond to a device that is to be detachably coupled to a hydration system, such as a backpack-based hydration system. The device may receive fluid from a reservoir included within the hydration system via a reservoir hose coupled to the reservoir. The device may include a pump and one or more valves that control the extent to which the fluid flows in and out of the interior of the pump. The fluid may exit a mouthpiece of the device based at least partly in response to a user applying pressure to the exterior surface of the pump, such as by the user squeezing or otherwise compressing the pump. The user may consume or otherwise use the fluid without having to apply suction to the mouthpiece of the device.

Fluid carrying apparatus having an outer helical tubular casing which, in use, holds fluid, and an inner helical tubular member within the outer helical tubular casing through which the fluid can be delivered from the outer helical tubular casing.

A jacket includes an inner harness, a jacket for wearing over the harness, and a load for attachment to the harness through attachment openings in the jacket. The load can be an airbag, a backpack, or other load or load carrying member for attaching to the harness. The jacket has at least one back opening providing access to the inner harness, to facilitate the attachment of the load to the harness. The jacket can be readily removed without disturbing the harness or its load. The removed jacket is effectively carried by the load and/or harness to which the load is secured. The inner harness can be used to carry loads without using the jacket.

An automatic pump hydration delivery system includes a power source, master power switch, electric pump, timer delay module, pressure switch, backflow prevention structure (such as a one-way valve), conduit or tubing, bite valve, and may contain a reservoir or be retrofitted onto prior-art reservoirs or hydration bladders.

Hydration apparatuses and methods of use, including, in one implementation, a hydration apparatus comprising a stiff outer shell defining a fluid reservoir, a drinking conduit extending from the stiff outer shell and having a first fluid channel in fluid communication with the fluid reservoir, a valve positioned in series with the first fluid channel, a pressurizing conduit extending from the stiff outer shell and having a second fluid channel in fluid communication with the fluid reservoir, and a pump coupled to the pressurizing conduit and located a distance from the stiff outer shell. The pump is configured to supply air to increase a pressure within the fluid reservoir above an ambient pressure. The hydration apparatus may be used in conjunction with a wearable hydration apparatus holder, sized and dimensioned to be worn by a user and to receive the stiff outer shell.

The present disclosure is directed to hydration backpack reservoir. The reservoir is a flexible liquid reservoir that includes a plastic bladder with a first side and a second side. A first slider lock track and a handle assembly are coupled to the first side. A catch/pour component is coupled to the second side. The first slider lock track and handle assembly are formed from a plastic with a first durometer and the catch/pour component is formed from a plastic with a second durometer softer than the first durometer. The handle assembly has a transversely extending cross bar that terminates in pinch tabs. Pinching the pinch tabs causes a scalable fill port to open.

Disclosed are flexible fluid reservoirs including a front sheet and a back sheet, each comprising a four-layer insulated wall. The four-layer insulated wall includes an interior layer and an exterior layer, and a metallic film layer and an insulation layer disposed between the interior layer and the exterior layer where the metallic film layer is oriented toward the exterior layer and the insulation layer is oriented toward the interior layer. One or more of the interior or exterior layers can be a metallocene modified polyethylene film. The metallic film layer can be aluminum coated polyethylene terephthalate resin. The insulation layer can be a foam layer comprising closed cell polyethylene resin. The four-layer insulated wall can resist or limit temperature changes of a fluid disposed within the reservoir for a period of time. The insulated fluid reservoirs can include closure mechanisms for sealing an upper opening of the reservoir.
