<P>PROBLEM TO BE SOLVED: To provide a spout for a nasal cavity by which waste liquid is stored in the head part of a vessel. <P>SOLUTION: A mounting cup 2 incorporating a valve mechanism is mounted on the head part of an aerosol vessel by a fastening part 2a. A flow path to be fitted to a stem projected from the valve mechanism is formed inside a spout base part with an operating part where a pipe shape nozzle 11 is projected. A liquid receiving part 20 to be abutted on a part in the circumference of the inlet of the nasal cavity is formed at a position which is nearer to the distal end of the nozzle than to the proximal end. While the nasal cavity is clogged by the liquid receiving part, content liquid is sprayed into the nasal cavity from the distal end of the nozzle by depressing an operating part 16. A liquid discharge groove 22 communicating with the liquid discharge port 21 of the liquid receiving part 20 is formed along the peripheral surface of the spout, and waste liquid is discharged onto the surface of the mounting cup at a side inner than the fastening part 2a. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
