Pour connector and pour port structure of liquid container

A pour connector that is connected to a pour port of a liquid container so at to pour a liquid into said liquid container, comprising:

• a cylindrically-shaped body portion having a pour passage therein;
• a lower end connecting portion that is integrally formed in a lower end of said body portion and that can be connected to the pour port of said liquid container while a lower end opening of said pour passage is aligned with the pour port;
• and
• a cap fitting portion that is integrally formed in an upper end of said body portion and that can be fitted with a cap for openably closing an upper end opening of said pour passage,
• wherein at least one guide piece is integrally formed in the body portion so as to be positioned between an upper end and a lower end of the pour passage of said body portion, the at least one guide piece protruding from a portion of an inner circumferential wall surface of said pour passage toward the center thereof and having a guide surface formed in an upper surface thereof, the guide surface being directed to a center of said pour passage and is downwardly inclined, so that said pour passage is partially closed by the at least one guide piece,
• wherein a gas guide portion is formed in a portion of said pour passage in which said at least one guide piece is formed, the gas guide portion being defined by a lower surface of said at least one guide piece and the inner circumferential wall surface of said pour passage, and
• wherein when said pour connector is connected to the pour port of said liquid container to use the same, a projection edge of said at least one guide piece is positioned below a base portion of said at least one guide piece on the inner circumferential wall surface gravitational direction, so that the liquid poured into said pour passage can flow toward the center while it is guided by said guide surface and continue flowing toward the center after it has been guided by said guide surface, whereas said gas guide portion is positioned above the projection edge of said at least one guide piece in the gravitational direction, so that gases in said container can be discharged from circumferential ends of said gas guide portion in a direction opposite to said pour direction.
