A liquid dispensing device includes a storage container having an opening and dome pump assembly attached thereto substantially over the opening for metered dispensing. The dome pump assembly is integrally formed with a dome button, top portion extension and valve to facilitate manufacture and reduce costs of the pump while improving performance thereof. The valve is employed to pull liquid from the storage container into the dome for metering. An exit passageway formed from the extension and container wall serves as an output valve. The user squeezes the dome and the opposite side of the container pouch concurrently to seal the flapper valve to urge liquid out through the exit passageway for actual dispensing.
