PROBLEM TO BE SOLVED: To make it possible to exactly transmit the pressing and contracting action by a knock to a valve mechanism by arranging a valve opening body for transmitting pressing force to a valve plug in a coating liquid housing part and providing this valve opening body with a wobble preventive part having a tapered shape of the diameter reducing toward the bottom of a coating liquid housing apart. SOLUTION: When the pressing force is applied to a tail plug 15, a thin-film part 15c ruptures and this tail plug 15 is separated to a pressing crown 15a and a tail crown 15b. When the plug is pushed further, the base of the blind cylindrical part 13a of a moving part 13 advances the valve opening body 12 and the valve plug 11 by overcoming the energizing force of an elastic body 10, thereby parting a valve part 11a and a seat part 6a and opening the valve mechanism. At this time, the valve opening body 12 moves in the coating liquid housing part 9 while the wobble is prevented by the wobble preventive part 14 consisting of four projections 14a disposed behind the valve opening body and the tapered apart 14b disposed successively therewith. When the valve mechanism is opened, the coating liquid in the coating liquid housing part 9 is passed through the inside of a projecting cylindrical part 6 and is discharged into a coating liquid occlusion body 5 and is further supplied to an application body 1, by which the application is made possible. |
