Abstract
A thermally insulated synthetic resin container formed by providing, within a space formed in between an inner container and an outer container which are joined as a single body and forms a double walled synthetic resin container, a thermally insulating synthetic resin layer having a double wall structure, which has gas having low thermal conductivity having a thermal conductivity lower than that of air, filled between the two walls; and said thermally insulated synthetic resin container which comprises a thermally insulating layer supporting means for securing to said double walled container said thermally insulating layer provided in the space within said double walled container, thereby preventing the rattling of said thermally insulating layer, eliminates the need for forming the metal plating film, and has superior thermally insulating capabilities and durability, and manufacturing thereof is easy and inexpensive, recycling of the synthetic resin is easy, the rattling noise produced when consumers use the containers or lids is eliminated, and the discrepancies in the index times are lost, thereby improving production management and quality control.
