A double-walled synthetic resin container wherein a gap between an inner container and an outer container holds a synthetic resin thermal insulator layer having a double-walled structure and filled with a low thermal conductivity gas having a thermal conductivity lower than that of air. Additionally, a double-walled synthetic resin lid wherein a gap between a top surface wall and a bottom surface wall holds a synthetic resin lid thermal insulator layer having a double-walled structure and filled with a low thermal conductivity gas having a thermal conductivity lower than that of air. A plating film does not need to be formed, thus reducing the manufacturing costs, increasing the freedom of design, and simplifying recovery of the synthetic resin.
L'invention vise un contenant de résine synthétique à double paroi, dans lequel l'espace compris entre un contenant interne et un contenant externe contient une couche thermo-isolante en résine synthétique ayant également une structure à double paroi, remplie d'un gaz de conductivité thermique inférieure à celle de l'air. De plus, un couvercle de résine synthétique à deux parois, où l'espace compris entre la surface supérieure et la surface inférieure contient une couche thermo-isolante ayant également une structure à double paroi, remplie d'un gaz de conductivité thermique inférieure à celle de l'air. Il n'est donc pas nécessaire de former un film de placage, ce qui réduit les coûts de fabrication, permet une plus grande souplesse de conception et simplifie la récupération de la résine synthétique.
