PROBLEM TO BE SOLVED: To provide a foam dispenser capable of always performing air sucking operation into a nozzle during one vertical movement operation of a dispensing operation member, performing suction inside even when there are residual foams in the nozzle, and preventing foam solidification or the like at a nozzle tip.SOLUTION: A foam dispenser includes: an outer shell member Ca fixed to be vertically movable in an upward pressed state with respect to a cylinder member B; and an inner shaft member Cb vertically movable by a predetermined width with respect to the cylinder member and vertically movable relatively to the outer shell member. When the outer shell member is lowered, the inner shaft member is lowered by a predetermined width and then rises relatively to the outer shell member, liquid in a liquid cylinder 11 and air in an air cylinder 10 are merged, foams are generated through a foam generation layer 80 and dispensed from a nozzle 41. During the rising of the outer shell member by an upward pressed force, the inner shaft member rises by a predetermined width, and then falls relatively to the outer shell member. Thus, a volume change occurs in a dispensing head to exhibit a back suction operation. |
