PCT No. PCT/JP90/01445 Sec. 371 Date Jul. 7, 1992 Sec. 102(e) Date Jul. 7, 1992 PCT Filed Nov. 7, 1990 PCT Pub. No. WO92/08657 PCT Pub. Date May 29, 1992.A foam dispensing, pump-actuated container to mix air and a liquid at a predetermined ratio has a mixing chamber at a juncture of a liquid flow path and an air flow path from an air cylinder, and the foam is homogenized by a porous sheet-like member provided on the downstream of the mixing chamber, and then dispensed through the dispenser nozzle. A liquid cylinder extends downwardly relative to the bottom surface of the air cylinder, so that a slidable portion of an air piston and a slidable portion of a liquid portion, both constituting the piston assembly of the foam dispensing pump, are set at different elevations for reciprocal movement. A check valve is provided in the air piston so that outer air is introduced into an air chamber defined by the air cylinder and the air piston through a gap around the outer circumferential surface of the air piston. The dispenser nozzle threadably engages the container such that the liquid in the container is sealed when the dispenser nozzle is threadably engaged with the container.
