| 1. A molten metal supplying container including a container having a passage communicating an inside and an outside of the
container and applying a pressure to the inside of the container, the container being capable of storing a molten metal and
allowing the molten metal to flow between the inside and the outside of the container owing to a pressure difference when
the pressure is applied to the container by a pressurizing gas supply unit via an air hose having a first socket at an end
portion of the air hose, comprising:
a first flow path, communicating the inside and the outside of the container, and allowing the molten metal to flow therein;
a first pipe disposed in the passage and having a plug at an end portion of the first pipe,
the first pipe extending to an upper direction from an upper portion of the container, and bending at a predetermined height
in a horizontal direction, and
the plug extending in the horizontal direction, the plug being configured such that the first socket can be detachably connected
to the plug, the plug and the first socket constituting a coupler structure;
a cap having a second pipe, a second socket, and a restricting member,
the second pipe being filled with the restricting member and provided with the second socket at an end portion of the second
pipe,
the second socket being detachably connected, in a case where the first socket is detached from the plug, to the plug of the
first pipe such that the second pipe connects to the first pipe, the plug and the second socket constituting the coupler structure,
and
the restricting member being configured to allow a gas to pass through the second pipe and restricting the molten metal to
pass through the second pipe in a case where the container stores the molten metal and is transferred, the restricting member
depriving the molten metal, when passing through the restricting member, of heat to solidify such that the solidified metal
restricts a further flow of the molten metal.
