Claims

[Scope of utility model registration request]

In an inverted container having a squeeze property and having a mouth at the lower end, a cylinder member having a discharge port at the tip is attached to the mouth, and a piston member is slidably fitted to the cylinder member by a predetermined stroke. The piston member is integrally provided with a piston slidingly in contact with the inner surface of the cylinder member at the upper end and a valve for opening and closing the discharge port at the lower end, and a metering chamber is formed between the piston member and the cylinder member. Further, a spring is provided that constantly pushes up the piston member and urges the valve to the discharge port closed position, and in this discharge port closed position, the piston of the piston member separates from the cylinder member, and the metering chamber is connected to the inside of the container. An inverted metered dose container configured to communicate.
