A liquid dispenser for a flush tank includes a dispensing closure in engagement with an open top container for axial movement relative thereto, the closure having discharge ports therein defining flow passages between the interior and exterior of the container and capable of being opened and closed during such axial movement. The closure includes a hollow cap having air vents therein, and a sleeve extending inwardly of the container so that liquid may flow during a tank refill operation through the ports and beneath the sleeve for thoroughly mixing with concentrated soluble material within the container before flowing into the cap while forcing the air through the vents. And, during a tank flushing operation, the mixed liquid is dispensed through the ports after it again mixes with the soluble material below the sleeve, the mixed liquid in the cap then being replaced by air through the vents during the discharge operation.
