PROBLEM TO BE SOLVED: To provide a fixed quantity applying device for applying a fixed quantity of an application object to a desired place with a simple structure, and usable by attaching to a commercially available container.SOLUTION: A fixed quantity applying device 1 includes: a nozzle 100 having first circulation holes 150 and 155, a filling chamber 160, and a through hole 162; and a piston 200 having a first slide part 215, a second slide part 220, a second circulation hole 270, a communication part 225, and a connection part 275. The fixed quantity applying device 1 is attached to an opening of a container in which an application object is stored. The fixed quantity of the application object in the container is filled in the filling chamber 160 by a force applied to the piston 200 from the opening through the second circulation hole 270, the communication part 225 and the first circulation holes 150 and 155, the piston 200 moves by a fixed amount in a direction along a shaft center X so as to make the first slide part 215 enter into the filling chamber 160 and apply pressure to the application object in the filling chamber 160, and the fixed quantity of the application object leaks to the outer peripheral surface of the nozzle 100 from the through hole 162.SELECTED DRAWING: Figure 1 |
