DISCHARGE CASE

PURPOSE: To aim to prevent liquid from drying, by having a liquid sealant with little volatility interposed between a valve seat and a valve disc in a valve mechanism for discharging liquid so that the air and the like do not enter a case body. CONSTITUTION: A mouth member 4 attached to the opening part of a case body 1 has a piston 5 in its inside, and a cylinder 10 is provided relative to the piston 5 so as to liquid-tightly slide. A nozzle body 14 provided on the upper part of the cylinder includes a nozzle member 15, a crown 16, and a thin plate-like member 17 which becomes a valve disc fixed in the intermediate part of a liquid flow passage 15a of the nozzle member 15. Between the thin plate-like member 17 and a valve seat 15b of the nozzle member 15 in contact with the underside of the thin plate-like member, a liquid sealant 19 with low volatility is interposed. Also, by pressing the crown 16, the cylinder 10 slides downward, deforming the thin plate-like member 17 to expand an outlet, thereby the liquid is discharged from the outlet 18. Thus, since the liquid sealant is interposed before using, the valve mechanism is sealed.
