ABSTRACT:
A double-walled, insulated portable cooler chest having a separate, self-contained, removable, non-insulated tapered liquid container disposed adjacent one end wall of said cooler and having a lower end wall hole and a dispenser tap therethrough communicating with the exterior through the end-wall of the chest. Liquid dispenser container is blow-molded of a polyolefin polymer with special lugs disposed on each side thereof to cooperatively engage wedge-shaped retaining shoulders in the interior side walls of the chest. An interior nut is utilized to screw threadably engage an inner extension of the tap in a manner so as to simultaneously maintain the tap and the liquid container in proper positions. The liquid container is provided with a lid closure for a top opening of a sufficient size to permit a person to extend one hand into the container for the purpose of removing the nut from the tap extension to permit removal of said liquid container from the cooler chamber for cleaning purposes. A tap assembly compressively confines the liquid container end wall and the end wall of the chest. The tapered chest wall shoulders cooperatingly urge the container end wall into contact with the interior end wall as the tapered container is pushed downwardly in the chest, thereby insuring proper tap hole alignment and secure confinement of the liquid container without stress on the tap that could result in misalignment and leakage.
