<P>PROBLEM TO BE SOLVED: To prevent dripping when bubbles remaining in a nozzle or the like liquify and also, prevent the dripping immediately after discharging. <P>SOLUTION: A discharger 1 discharging a liquid composition in a foam includes: a pump 2 attached to a mouth portion 12 of a vessel 11 in which the liquid composition is housed and mixing the liquid composition transferred from the vessel 11 inside and air transferred from the outside of the vessel 11 in a gas-liquid mixing chamber 6 by pushing down a stem 21 for pneumatic transport; a foam member 3 foaming a gas-liquid mixture pneumatic-transported by the pump 2; and a pushing-down head 4 attached to the stem 21 and having a nozzle 40 discharging bubbles foamed by the foam member 3. The nozzle 40 is provided projecting from a wall part of the pushing-down head 4, an opening area of the nozzle 40 end being ≥3.0 mm<SP>2</SP>and ≤20.0 mm<SP>2</SP>, and the sum of the content product of a circulation channel 44a from the foam member 3 to the nozzle 40 and the content product of the nozzle 40 being ≥0.08 ml and ≤0.20 ml. <P>COPYRIGHT: (C)2010,JPO&INPIT |
