Portable beverage coolers and methods of using the same. An exemplary cooler described herein comprises an outer shell having a general shape as a container, suitable to receive contents therein, a handle pivotally coupled to the outer shell a removable insert configured to fit within the outer shell, said insert configured to receive a liquid or other items therein, and a hinged lid coupled to the outer shell. Said coolers are configured to retain a beverage therein, maintaining a desired cold temperature, and to dispense beverage directly therefrom via a tap.

Bite-actuated mouthpieces and drink vessels including bite-actuated mouthpieces are disclosed. Bite-actuated mouthpieces comprise a body comprising a dispensing wall, one or more sidewalls extending from the dispensing wall that with the dispensing wall define an internal volume, and an inlet to the internal volume. The self-sealing exit is biased toward a closed configuration and is configured to be selectively reconfigured from the closed configuration to an open configuration responsive to user-applied compressive forces to opposing bite regions. The dispensing wall has a dispensing face opposite the internal volume, and in some examples, the dispensing face is concave.

Bladders/containers designed to hold a meaningful amount of material (in any state: solid, liquid or gas) to conductively absorb heat from the human body. In addition, the material may be consumed by the user wearing the bladder/container, thus providing a source of hydration for the user. The bladders/containers would also enhance impact and/or ballistic protection of the user.

The system may be a device that allows for mixture of an additive to a substance in a line of flow. The system may include a hydration pack with a reservoir that may contain a first substance, such as water. The system may include a cartridge with an additive that is mixed to the line of flow through a Venturi which may include a rolling seal that is manipulated with a dial a user manipulates to adjust the amount of additive added to the line of flow. The mixed liquid may then be accessed through a hose from the system to a mouth piece. The system may be modular to allow a user to replace the cartridge by disengaging a first component and a second component of the system through a buckling mechanism and replacing the cartridge within the second component. The cartridges may be reusable, recyclable or disposable.

A method and apparatus for dispensing a liquid when licked is disclosed. The apparatus comprises a substantially spherical member; a cap member, and a valve. The cap member comprise a concave member adapted to accept a spherical cap and retaining the spherical member within the concave member while forming a volume therebetween, and a valve, in sealed hydraulic communication with the volume between the spherical member and the concave member, the valve permitting fluid communication between the volume and a vessel sealingly affixed to the cap member in a first configuration and prohibiting fluid communication between the volume and the vessel in a second configuration.

Disclosed herein is an athletic apparel with a pouch for carrying a removable hydration pack. The athletic apparel may have a hydration pack that is fluidly connected to a channel for hydration during exercise. The athletic apparel may use a fastener to secure the removable hydration pack within the pouch and a fastener to secure the fluid channel to the apparel. The pouch may be opened to remove the hydration pack.

A hydration pack includes a main body, a strap, a bladder, a hydration tube, a first chain of magnets, and a second chain of magnets. The main body defines a storage compartment. The strap is coupled to the main body. The bladder is disposed in the storage compartment of the main body and configured to retain liquid. The hydration tube includes a proximal end coupled to the bladder and a distal end. The first chain of magnets is disposed on the strap. The second chain of magnets is disposed along a length of the hydration tube. The first and second chains of magnets are configured to connect by magnetic forces and disconnect by a force exceeding the magnetic force of the first and second chains of magnets.

Personal hydration systems with cooling and/or warming capability, and the components thereof are disclosed. The personal hydration systems may include a liquid transport system for transporting cooling or heating fluid between a reservoir and a pad, which pad is configured for wearing adjacent to a wearer's body. A pump is provided for pumping the liquid through the system. A drinking tube is connected to the system for removing liquid from the system. Liquid can be removed from the system for drinking by sucking on the end of the drinking tube. A check valve is used to bypass the pump so the user will not have to suck the liquid through the pump. Alternatively, liquid can be removed by spraying the liquid out of the drinking tube using the power of the pump.

A hydration system including a fluid reservoir, a fluid path in communication with the reservoir, and a magnetic quick connect interposed in the fluid path is disclosed. A fluid delivery system for a hydration system is also disclosed that includes a magnetic quick connect interposed in a fluid delivery path of the delivery system. The magnetic quick connect can also be used in a wide variety of fluid delivery systems. A kit for forming a fluid delivery system for a hydration system is also disclosed, as are various components of a hydration system.

A hydration backpack includes a main body, a storage compartment, a pair of shoulder straps, a bladder, a hydration tube, a first longitudinal elongated metallic element, and a second longitudinal elongated metallic element. The bladder is disposed in the storage compartment of the main body and is configured to retain liquid. The hydration tube includes a proximal end coupled to the bladder and a distal end providing liquid to a user on demand. The first longitudinal elongated metallic element is disposed on one shoulder strap. The second longitudinal elongated metallic element is disposed on the hydration tube. The first and second longitudinal elongated metallic elements are configured to connect by gravitational and magnetic forces and form an automatic hydration tube return system.
