ABSTRACT:
An insulated container having a pump for generating air pressure over the liquid in the container so as to selectively dispense it. A valve arrangement is incorporated that prevents inadvertent displacement of the liquid from the container if the pump is accidentally actuated. The valve arrangement prevents discharge of liquid from the discharge spout and also prevents the transmission of air pressure from the pump to the area in the container over the liquid.
