Abstract
A foamer mechanism () of a foam dispensing container has a gas-liquid contact chamber (), a liquid agent flow passage () through which a liquid agent supplied from a liquid agent supply portion () to the gas-liquid contact chamber () passes, and a gas flow passage () through which a gas supplied from a gas supply portion () to the gas-liquid contact chamber () passes. The gas flow passage () has a gas opening () that is open to the gas-liquid contact chamber (). The liquid agent flow passage () branches into plural branch flow passages (for example, branches into a first branch flow passage () and plural second branch flow passages ()). Each of the plural branch flow passages has a liquid agent opening () that is open to the gas-liquid contact chamber (). The liquid agent openings () are respectively arranged at positions on the both sides sandwiching an extension region () of an adjacent flow passage () which is a part of the gas flow passage () adjacent to the gas opening ().
