Container for eye drops

摘要

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.

1. A container for eye drops comprising:
a flexible and restorable container main body for housing a medicinal solution; a medicinal solution passage communicating with the container main body, for discharging the medicinal solution housed in the container main body when the container main body is pressed and deformed; a stopper member fixed to an inside of the medicinal solution passage, having a tip portion at a downstream side in a medicinal solution discharge direction, the tip portion having a predetermined-shaped cross section when viewed from the medicinal solution discharge direction; a pressure valve arranged, in the medicinal solution passage, at a downstream side in the medicinal solution discharge direction further than the tip portion of the stopper member, and being formed with an opening in a center portion thereof having a predetermined-shaped cross section that contacts the tip portion; and a biasing member provided, in the medicinal solution passage, at a downstream side in the medicinal solution discharge direction further than the pressure valve, 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, wherein the pressure valve is made of a material to that is easily deformed by a fluid pressure, and a peripheral portion of the pressure valve is supported and fixed to the inside of the medicinal solution passage.
