PROBLEM TO BE SOLVED: To improve inhibitory effect against the inflow of outside air through a flow channel of a spout portion.SOLUTION: A spouting tool comprises a spout portion (a support wall 26) forming a flow channel connected to a spout therein. In the flow channel, a non-return valve 30 for restricting the flow from the spouting side to a container side is provided. The non-return valve 30 includes: a case member 31 for partitioning the flow channel into the spouting side and the container side; a film-like valve body 35, which is disposed on the spouting side of the case member 31, for blocking a flow path 32 that is formed in the case member 31 so as to penetrate; and a holding member 36 for holding the valve body 35 between the case member 31 and itself. |
