ABSTRACT:
A press type thermos bottle comprises a bottle body with an internal liquid tank, a lower cover collared onto the upper end of the bottle body having a water pipe inset in the liquid tank and a through hole at its front end for one end of the water pipe to project out, and an upper cover having its rear end screw-jointed with the rear end of the lower cover and its front end snap-retainable to the front end of the lower cover. A valve disposed in the upper cover is pivot-jointed to a press mechanism via a connecting rod, wherein the lower end of the valve is inset in an air supply mechanism that is used to force water to flow out from the tank through the water pipe when the press mechanism is pressed.
