This foam dispenser includes a flexible container for foamable liquid, having a discharge opening at the upper end. A porous member is housed in the discharge opening and a conduit communicating with said porous member extends downwardly into the interior of the container. A flow directing valve system within the conduit determines the path of air and liquid through the conduit and the porous member during manual pressurization and depressurization of the container. The foamable liquid and air are isolated from each other by a bag member disposed within the container.
