Disclosed is a liquid container having a pumping device with a simple structure. The liquid container has a container portion for containing liquid, a first valve installed on the opening of the container portion, a pressing portion installed on the first valve, and a second valve installed on the pressing portion. The first valve allows outflow of the liquid in the container portion, and prevents inflow of the liquid into the container portion. The pressing portion forms a pressing space on the outer , side of the first valve, and is made of soft material. The second valve allows outflow of the liquid in the pressing space, and prevents inflow of the liquid into the pressing portion. The first valve and the second valve have a protrusion protruding outward and formed with slits. The protrusion is made of soft material so. that the slits are opened and closed elastically. As the pumping device and the liquid container is constituted by a small number of parts, the manufacturing cost is low, the manufacturing process becomes simple, and the breakdown of the product is rare. |
