PROBLEM TO BE SOLVED: To arbitrarily vary the discharge volume on using, by partitioning a metering stopper body into a measuring chamber surrounded by a partition plate, the top plate of a cover, and the upper peripheral wall than the inflow aperture of the body, a waiting chamber, and a discharge hole. SOLUTION: A cover 200 is fitted to the body 100. The partition plate 300 is inserted from the insertion aperture 212 of the cover 200 so as to form a clearance 13 from the bottom of the body. The metering stopper 10 is partitioned to a measuring chamber 11 surrounded by the partition plate 300, the top plate 210 of the cover 200, and the upper peripheral wall 110 than the inflow inlet 111 of the body 100, a waiting chamber 12 surrounded by the partition plate 300 positioned below the measuring chamber 11, the clearance below the partition plate 300, the lower peripheral wall 110 than the inflow inlet 111 of the body 100, and the bottom wall 120 of the body 100, and a discharge hole 14 adjacent to the measuring chamber 11 and the waiting chamber 12 through the partition plate 300, surrounded by the partition plate 300 and the clearance 13 below the partition plate 300, the discharge outlet 211 of the cover 200, the peripheral wall 110 of the body 100, and the bottom wall 120 of the body 100. |
