PROBLEM TO BE SOLVED: To provide a metering discharge container in which a required volume of liquid can be easily measured without visual confirmation while the discharge volume can be made variable and the liquid hardly leaks out of the measuring cup. SOLUTION: A measuring cup 4 is formed to have a cylindrical space with a bottom by a cylindrical side frame 9 and the bottom 8 and a freely and relatively rotating rotary inner cylinder 11 is fitted inside in the cylindrical space. And an upper pouring outlet pipe 15 inserted in a sliding guide cylinder 16 which vertically moves in the rotary inner cylinder 11 through a screwing part and of which lower part is formed at the bottom 8, through a fitting structure allowing only the vertical movement, is provided at the center of the rotary inner cylinder 11. The upper pouring outlet pipe 15 is vertically moved by the rotary movement of the rotary inner cylinder 11 to make variable the distance from the discharge outlet hole 14 to the bottom 8 of the rotary inner cylinder 11. |
