ABSTRACT:
A disposable container for a liquid such as soy sauce, detergent or cosmetics, discharges its contents when the container is folded over and pressure is applied to the container by the palm or fingers of the hand. The container includes a sealed portion that has a narrow width and which is formed into a circular, elliptic, rhomboid or other shape in such a manner that the center of the sealed portion coincides with the center line of the container about which the container may be folded. A discharge port is formed in the central portion of the sealed portion or in the side of the container from which the contents are desired to be discharged so that when the container is folded over and pressure applied thereto to rupture the sealed portion, the contents of the containers are discharged through the discharge port.
