を特徴とする定量吐出容器。 A flexible bag body 22 for storing liquid contents is provided in a container main body 21 provided with an upper surface opening, and a discharge mechanism 23 discharges the liquid contents into the bag body 22 by a pressing operation. The dispensing mechanism 23 includes a cylindrical spout member 26 that is set in the upper opening of the container body 21 and is provided liquid-tightly with respect to the housing 22, and A stopper member 27 is attached to the stopper member 26, and a discharge port 31 for liquid contents is formed on the upper surface of the stopper member 27, and a pressure chamber R is formed inside the container body. A pressure plate 29a is provided that bulges above the plug member 21, and the plug member 27 is provided with a flow path 28b that communicates the pressure chamber R with the liquid reservoir chamber 28a in the plug member 27. At the upper end of this flow passage 28b is a check valve 32 which closes when the internal pressure of the pressure chamber R increases and opens when negative pressure increases.
Furthermore, a through hole 2 is provided at the base end of the plug member 26, which communicates between the liquid reservoir chamber 28a and the inside of the bag body 22.
6b, and the plug member 27 is provided with a pressure chamber R and a discharge port 3 when the pressing plate 29a is pressed.
1. A fixed-quantity dispensing container characterized by being provided with a discharging path 33 that communicates with 1.
