<P>PROBLEM TO BE SOLVED: To ensure an adequate foam quality even when the viscosity of a liquid is high. <P>SOLUTION: A discharger 1 includes a pump 3 having a stem which is erected in a downward movable manner while it is upwardly urged, and a depressing head 4 provided on an upper end of the stem 5, and discharges foam consisting of the liquid transferred by the pump 3 and air from a nozzle hole 37 formed in the depressing head. The pump 3 includes a liquid cylinder 6 with a liquid piston 7 sliding interlockingly with the stem 5 being accommodated therein, and an air cylinder 8 with an air piston 9 sliding interlockingly with the stem 5 being accommodated therein. A distribution passage 13 extends from an upper end of the stem 5 to the nozzle hole 37, and the liquid transferred from the liquid cylinder 6 flows through the stem 5. A jetting port 47 for jetting air transferred from the air cylinder 8 through an air passage 14 is arranged inside the distribution passage 13, and a porous body 48 capable of allowing air to pass therethrough is provided on the jetting port 47. <P>COPYRIGHT: (C)2010,JPO&INPIT |
