Claims (1)

[Claims for Utility Model Registration] (1) The hollow part of the stopper body, which is a hollow body with a bottom and is fitted into the mouth of the container, is partitioned by a partition wall extending from the opening of the stopper main body toward the bottom; One of the opening parts of the stopper body is closed with a top plate, and the hollow part of the stopper body has a liquid storage part on the bottom side, a measuring part partitioned by a partition wall and closed by a top plate, and a measuring part partitioned by a partition wall. An air port communicating with the metering section and a liquid inlet are formed in the circumferential wall of the stopper body, and an air port and a liquid inlet are provided near the bottom and the top plate of the stopper body, respectively. The provided liquid metering dispensing stopper communicates between the inside of the container and the stopper main body, has a sufficiently large flow resistance so that air bubbles do not enter against the surface tension of the liquid, and has an opening inside the stopper main body that is as described above. A liquid dispensing stopper characterized in that the stopper body is provided with a drain passage located closer to the bottom than the part of the distal end edge of the partition wall closest to the top plate. (2) The plug body is formed by a cylindrical cylindrical member and a bottom member that is fitted into the cylindrical member to form a bottom, and the drain passage is one of the parts where the cylindrical member and the bottom member contact each other. Alternatively, the liquid dispensing stopper according to claim 1, which is characterized in that it is formed by grooves provided on both sides.
