Patent ID: 7507366

Claim:
A container capable of being hermetically closed and storing a molten metal and supplying the molten metal to an outside using a pressure difference, comprising: a frame body having an opening at an upper portion thereof; a heat insulating wall laid onto an inner wall of the frame body; a refractory storing bath, detachably inserted to an inner side of the heat insulating wall from the opening of the frame body to be integrally provided with the frame body; a refractory and insu 1 ating member in a solid form containing a binder having a fusing point higher than that of the molten metal, inserted between the heat insulating wall and the refractory storing bath; a lid that covers the opening of the frame body; an introductory portion that introduces a gas for applying pressure into the storing bath covered with the lid; and a supplying portion that supplies the molten metal stored inside the storing bath to an outside, wherein the storing bath is formed so that a protruding portion extending to a vertical direction is formed on an inner side of the container and the flow path for the molten metal is provided inside the protruding portion, the flow path being made of ceramics, wherein the storing bath is comprised of a seamless rigid body of ceramics having at least two engaging members fixed to an upper surface, outer surface or an inner surface thereof enabling a connection with an outside, and wherein at least a part of the flow path is surrounded by a pipe made of ceramics.
