Abstract:
1. A hydration system, comprising: opposing flexible walls forming a bladder having a sealable compartment for containing a liquid, a drinking tube having a first end with a valve and a second end; a first port configured to receive pressurizing gasses into the compartment; a baffle connecting the opposing walls within the compartment, the baffle configured to oppose expansion of the bladder as the pressurizing gasses are introduced into the compartment; a second port configured to provide fluid communication between the compartment and the drinking tube; a third port through which the liquid can be supplied into the compartment; wherein, when sealed and pressurized, activation of the valve unseals the compartment and allows the liquid to be expelled from the compartment via the second port and the drinking tube as a result of a pressurization of the compartment by the pressurizing gasses; and a transfer coil having a first end coupled to the first port and a second end coupled to a fourth port, the fourth port defining an entry from the transfer coil into the compartment, the transfer coil having a surface positioned to be in at least indirect contact with the liquid in the compartment; and a cartridge holder configured to detachably couple to the first port, the cartridge holder configured to hold and to cause a cartridge to mate with the first port allowing pressurizing gasses to expel from the cartridge into the compartment via the transfer tube; wherein pressurizing gasses when expelled from the cartridge have a cooling effect transferred to the liquid via the surface while pressurizing the compartment.
