A portable liquid dispenser includes a blow molded housing defining a cavity within the entire interior thereof. A centralized walled aperture is provided to receive an appropriate dispensing pump, the pump being configured to extend outwardly in a usable position and to lock in an inwardly position where the dispensing nozzle of the pump does not extend beyond the sidewalls of the dispenser itself. A fill and relief valve is provided to accommodate rapid filling of the dispenser during a manufacturing process, and to accommodate breathing of the container during the dispensing operation such that the unvented pump does not result in any distortion of the dispenser as the liquid therein is depleted.
