Abstract:
Provided with a discharge container that is easy to produce and maintains a constant discharge rate per unit time from the beginning to the end. This discharge container is provided with a bottle, a valve assembly configured to close an opening of the bottle and having a valve mechanism, and a pressure regulating mechanism accommodated in the bottle and configured to regulate the internal pressure of the bottle. The pressure regulating mechanism is attached to the lower end of the valve assembly.

Claim (Index 1):
A discharge container comprising:\n a container; a valve assembly configured to close the container, the valve assembly including a valve mechanism; and a pressure regulating mechanism attached to a lower portion of the valve assembly, the pressure regulating mechanism being configured to raise internal pressure of the container to predetermined pressure when the internal pressure drops, wherein the pressure regulating mechanism includes a cylinder portion provided below the valve assembly, a piston vertically slidably inserted in the cylinder portion to divide the cylinder portion into a pressure regulating chamber and an open chamber opened in the container, and a gas container filled with a pressurizing agent and communicated with an inside of the container in conjunction with a vertical movement of the piston, when a force received by internal pressure of the container is smaller than a force received from the pressure regulating chamber, the piston moves to open the gas container so that a capacity of the pressure regulating chamber becomes larger than a predetermined capacity to supply the pressurizing agent into the container, and when the force received by the internal pressure of the container is the same or larger than the force received from the pressure regulating chamber, the piston moves to close the gas container so that the capacity of the pressure regulating chamber becomes the same or smaller than the predetermined capacity.
