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.

A spray adaptor includes a main adaptor element having a pair of spray nozzles and a connector attached to the main adaptor element. A sprayer for spraying collunarium is prepared by fitting the connector of the spray adaptor to an outlet of a syringe. The collunarium discharged from the syringe is guided to the spray nozzles and sprayed into both nostrils at one time.

In a pump mechanism for ejecting liquid, an upper inside wall of a bell-shaped portion which is formed around a lower end of a first piston constitutes a guide surface inclined upward toward an axial hole of the first piston. The guide surface serves to prevent entrapping of air underneath the upper inside wall of the bell-shaped portion, or in an upper part of a metering chamber and stabilize the amount of liquid measured in each successive spraying action.
