<P>PROBLEM TO BE SOLVED: To provide a tilt type valve for an aerosol container capable of assuring a stable tilting action by a leaf spring integrally formed by synthetic resin. <P>SOLUTION: An annular seat groove 15 for seating an inner circumferential part of an annular stem gasket 5 is formed at an outer circumferential surface of a stem 10 so as to seal a stem hole 12. As the stem 10 is operated to tilt, a clearance is generated between a flat annular seat surface 16a below the seat groove 15 and a rear surface of the stem gasket 5 to enable the stored substances fed into a housing 3 to be discharged out through a stem hole 12. A bottom surface 16b of a stem base end section 16 forming the seat surface 16a at its upper surface is formed in a tapered shape where its outer diameter is gradually decreased toward the base end. A plurality of leaf springs 18 are integrally formed facing toward the leading end at a circumferential position with the center line in a longitudinal direction of the stem 10 at the bottom surface of the housing 3 so as to cause the extremity end 18a to be abutted against the bottom surface 16b. <P>COPYRIGHT: (C)2003,JPO |
