PROBLEM TO BE SOLVED: To provide a measurement discharge device which enables improvement of the operability and achieves reduction of the number of components to reduce the costs.SOLUTION: A measurement discharge device includes: a cap body 2 attached to a mouth part 11 of a container body 10 and having a suction pipe 25, the cap body 2 in which a discharge hole 26 is formed; a cylinder 3 attached to the cap body 2, the cylinder 3 including a measuring room 3A formed therein and into which a content from the suction pipe 25 is introduced; and a piston 4 which is slidably fitted in the cylinder 3. A valve seat hole 22a which allows the suction pipe 25 and the measuring room 3A to communicate with each other is formed in the cap body 2. An introduction valve 36, which is seated on an opening peripheral part of the valve seat hole 22a in the cap body 2 so as to separate therefrom, and a supply hole 37, which supplies the content from the measuring room 3A to the discharge hole 26, are formed in the cylinder 3. A discharge valve 28, which is seated on a discharge hole 26 side opening peripheral part of the supply hole 37 in the cylinder 3 so as to separate from the discharge hole 26 side, is formed in the cap body 2. |
