Zusammenfassung:	PROBLEM TO BE SOLVED: To (1) provide a small pressure vessel in which corrosion of a sealing plate is prevented over a long period in a condition of the pressure vessel being incorporated in a pressure fire extinguisher, (2) provide the fire extinguisher preventing pollution of a room, the pollution occurring due to gas leakage from the small pressure vessel, insufficient extinguishing capacity, and leakage of an extinguishing liquid caused by the gas leakage, even when the small pressure vessel is stored over a long period of time, and (3) manufacture the small pressure vessel without causing problems in environmental pollution. SOLUTION: The small pressure vessel comprises a vessel body and a mouth portion. An opening portion of the mouth portion is sealed by the sealing plate. The pressure vessel is filled with gas for extruding liquid. The vessel body and the mouth portion are integrally molded from a zinc-nickel alloy plated steel sheet. COPYRIGHT: (C)2007,JPO&INPIT
