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.

Des protubérances (43) et des évidements appariés (44) constituant une charnière conçue pour interconnecter un récipient (20) et un couvercle (30) moulés par soufflage et à double paroi sont formés de manière à pouvoir être pressés l'un contre l'autre alors que lesdits évidements (44) sont encore chauds après le moulage. Les protubérances (43) et les évidements (44) de la charnière sont assemblés et les espaces inter-parois du corps (20) et du couvercle (30) sont chacun remplis d'une matière isolante fluide (50) qui durcit et permet d'obtenir une charnière assemblée résistante et durable.
