ABSTRACT:
A nozzle includes a top portion projecting in the same direction as an opening of a container, and a plurality of liquid-medicine passages formed at an outer periphery of the top portion. When the container is inclined, a liquid medicine in the container leaks out therefrom via orifices of the individual liquid-medicine passages communicated with the opening of the container, so as to form a droplet on an outside surface of the top portion, whereby the liquid medicine is applied in a droplet.
