<p>This foam discharge device is configured in such a manner that a pump (11) is provided with: a piston (18) for liquid, the piston (18) coordinating with a stem (12); a cylinder (19) for liquid, the cylinder (19) having vertically slidably received therein the piston (18) for liquid; a piston (16) for air, the piston (16) coordinating with the stem (12); a cylinder (17) for air, the cylinder (17) having vertically slidably received therein the piston (16) for air; and a gas-liquid mixing section (M) for mixing the liquid from the cylinder (19) for liquid and air from the cylinder (17) for air and foaming the liquid. The cylinder (17) for air is disposed on the inside of a mounting cap (4) and is received within a container body (1). A head-side cylinder (54) for air, to which a piston tube (8) raised from the top wall section of the mounting cap (4) is vertically slidably fitted, is extended from a push-down head (14). A connection passage (R2) for connecting the inside of the head-side cylinder (54) for air and the inside of the cylinder (17) for air is formed in the pump (11).</p> |
