The lid of the table air pot includes in combination a bellow-type pump device for pumping up the liquid contained in the bottle into a drink cup while the air pot stands upright on a table, and a plug fixed to the bottom of the pump device for closing the bottle when the lid in its closed position. The tube for discharging the liquid from the bottle in response to the operation of the pump device is fixed on the upper supporting means for the bottle and is physically separated from the plug of the lid. Thus, the table air pot according to this invention can become ready to be filled with liquid by a single operation of opening the lid without need of removing the liquid tube.
