摘要： A liquid pouring member capable of effectively preventing the liquid from spouting upon opening. An inner plug includes a nozzle, a base to be engaged with an opening of a container, and a hollow cylindrical skirt. The nozzle includes a nozzle upper part extending from an upper surface of the base and a nozzle lower part extending from a lower surface of the base. The nozzle upper part includes an outlet port, and the nozzle lower part includes an inlet port. An inner passage is formed from the inlet port to the outlet port while penetrating therethrough. The nozzle lower part is formed in a radial inner side of the hollow cylindrical skirt, and includes an end portion with an inclined surface. The inlet port is formed in the inclined surface.
