BLOW-MOLDED SNAPPED-TOGETHER HINGE FOR DOUBLE-WALLED BODY AND LID

摘要

Projections (43) and mating recesses (44) for a hinge interconnecting a blow-molded double-walled container (20) and lid (30) are formed to be snap fit together while the recesses (44) are warm from molding. The hinge projections (43) and recesses (44) are assembled, interwall spaces of the body (20) and lid (30) are each filled with a pourable insulation material (50) that sets to make the assembled hinge strong and durable.
