Abstract: A hydration system that includes a flexible reservoir coupled to a self-sealing port assembly, wherein an interior of the flexible reservoir is in fluid communication with the port assembly; a delivery conduit having two ends, wherein a first end of the delivery conduit is coupled to a self-sealing connector assembly and wherein a second end of the delivery conduit is coupled to an end fitting; a user actuable valve removably coupled to the self-sealing connector assembly; and wherein the port assembly is open to allow fluid to flow from the flexible reservoir when the end fitting of the delivery conduit is coupled to the port assembly and the port assembly is closed to prevent fluid from flowing from the flexible reservoir when the end fitting of the delivery conduit is decoupled from the port assembly, such that the reservoir may be disconnected from the delivery conduit without leakage.

Abstract: A hydration pouch with a releasable coupling is disclosed. In one embodiment, the hydration pouch is a flexible bag or pouch with a separate inlet and outlet. A hose or tube is provided for a user to draw refreshment from the pouch. A bite valve is provided at one end of the tube to be actuated by a user's teeth. A coupling is provided for attaching and detaching at least a portion of the hose at an opposite end of the hose. The coupling includes a shutoff or check valve that maintains the patency of the pouch when the hose is disconnected. In an alternative embodiment prefilled, disposable hydration pouches are removably coupled to the hose and then disposed and replaced following consumption of the liquid contained therein.
