Claims (1)

[Claims for Utility Model Registration] In an inverted container equipped with a metered discharge mechanism at the lower end, the metered discharge mechanism is fitted into a cylinder member attached to the mouth of the container and slidably into this cylinder member with a constant stroke. A metering chamber is formed between the combined cylindrical piston member, a discharge port formed in the piston member, and an inner stopper attached to the container mouth above the discharge port, and an inflow port communicating with the metering chamber; a valve portion connected to the piston member so as to close the inflow port when the piston member is pushed up; a spring that constantly pushes the piston member downward; and the discharge port. and a valve attached to the metering chamber for high viscosity solutions, the valve is always biased to the closed position by a spring member and is configured to open when the piston member is pushed up and the internal pressure of the metering chamber increases. container. The discharge port is formed near the inner middle of the cylindrical piston member, and the discharge port has a reservoir portion for the discharged internal solution formed in the lower part of the discharge port.
