| 摘要 |
The present invention relates to a thermally insulated synthetic resin container (1) and a thermally insulated synthetic resin lid (21). The synthetic thermally insulated container (1) has a thermally insulating layer (4) formed in the space between the inner container (3) and the outer container (2), which comprise at least one synthetic resin selected from among the group comprising polyester, aromatic polyamide, polyketone, polyvinylidenefluoride, acrylonytrile-type resin, and cycloolefin-type resin, with a low thermally conductive gas having a thermal conductivity lower than air sealed therein. Similarly, the thermally insulated synthetic resin lid (21) has an thermally insulating layer (24) formed in the space between the synthetic resin lower lid member (22) and the upper lid member (23). The thermally insulated synthetic resin container (1) and lid (21) can be made from only one type of resin, are easy to manufacture, and are superior in thermal insulation performance and maintaining thermal insulation performance over time.
