Claims

[Scope of utility model registration request]

In a quantitative dispensing device that dispenses a predetermined amount of fluid in a container from the dispensing side, a predetermined outflow resistance is provided in the discharging direction to prevent fluid leakage from the discharging side of the container, allowing the fluid to flow away. A fluid leakage prevention structure for a fixed-quantity dispensing device, characterized in that a check valve is provided on the discharging side of the container.
