A liquid foam-discharging, squeezable bottle is disclosed, which has a twist cap screwed onto the vessel body, the twist cap being composed of an inner cap and outer cap. The inner cap has formed therein two independent fluid-passing mechanisms at about its central position and at a position adjacent thereto, respectively. One of the fluid-passing mechanism is a liquid foam-generating mechanism comprising a pipe-shaped member having a net screen on one end thereof, and the other functions as a check valve. The outer cap has engaged inside of the foam-discharging opening an adapter fully covered with a net screen on one end located nearer to the contents of the vessel. This vessel enables one to rapidly discharge a uniform, creamy liquid foam by simple squeezing operation and, if desired, the foam can be sprayed by using an adapter having a small-diameter nozzle.
