Abstract:
The foam-dispensing pump container according to the present invention has the valve seat portion which protrudes inwardly below the air-liquid mixing unit and which is formed of the flexible member that can come into contact with the outer peripheral face of the latch portion of the rod-shaped valve body, and immediately after the nozzle head starts rising, the flexible valve seat portion comes into contact with the rod-shaped valve body before the upper opening end of the liquid chamber comes into contact with the rod-shaped valve body, thereby significantly reducing a backflow of the foam or liquid into the air passage, and consequently improving the usability of the foam-dispensing pump container.
