PURPOSE: To position an injection nozzle so as to be opposed correctly to an eye by installing an adaptor in a vessel main body so as to be freely detachable and providing a positioning part for allowing it to abutted on a nose root part in an adaptor.

CONSTITUTION: The eye lotion vessel is constituted by combining a vessel main body 10 and an adaptor 20 and the vessel main body 10 is a vessel having an injection nozzle 11 and the injection nozzle 11 can be opened/closed by a cap 12 with a screw. The adapter 20 is constituted by forming integrally a blade part 21 for holding the vessel main body 10 from both sides therebetween and a positioning part 22 in its rear part and can be installed in the vessel main body 10 so as to be freely detachable by engaging an engaging projecting part 21a to an engaging groove 10b. The positioning part 22 is raised like a belt in the upper part of a connecting part 25, the tip part 22a is bent in the rear while curving to the lower part, and a reinforcing rib 22b is formed on the lower face of the tip part 22a. When the positioning part 22 is raised to an erect attitude, and the tip part 22a is allowed to abut on a nose root part, the injection nozzle 11 can be held while opposing correctly to an eye.
