Abstract
A flexible and restorable container main body for housing a medicinal solution. A stopper member is fixed in an inside of a medicinal solution passage that communicates with the container main body for discharging the medicinal solution when the container main body is pressed and deformed. A pressure valve is arranged in the medicinal solution passage at a downstream side in the medicinal solution discharge direction further than the stopper member and is formed with an opening having a circular cross section which contacts a tip portion of the stopper member. A biasing member is provided at a downstream side for biasing the pressure valve in a direction opposite to the medicinal solution discharge direction by abutting against a peripheral portion of the opening of the pressure valve.
