Abstract
Projections and mating recesses for a hinge interconnecting a blow-molded double-walled container and lid are formed to be snap fit together while the recesses are warm from molding. The hinge projections and recesses are blow molded without forming any opening through a hinge wall into an interwall space. After the hinge projections and recesses are assembled, interwall spaces of the body and lid are each filled with a pourable insulation material that sets to make the assembled hinge strong and durable.
