A portable liquid dispenser suitable for use by persons while performing an activity comprises a thermally-insulated container for liquids having a fastener for releasably attaching the same for access by the user. A single flexible dispensing tube having a pair of parallel longitudinal passages is connected at one end connected to the filling cap of the container and at the other end to a dispensing valve for discharging liquids from the container. The container is pressurized by a compressible bulb sealed end around the distal end of the dispensing tube in communication with the interior of the container through one longitudinal passage in the tube. A check valve is disposed in the air inlet of the fitting and another check valve is disposed in the air inlet of the dispensing valve which cooperate with the bulb to force air into the container. A number of compressions of the bulb forces air into the container to pressurize the liquid therein which flows through the other longitudinal passage on demand of the user by pressing a plunger on the dispensing valve.
