Abstract: The present invention relates to a thermally insulated synthetic resin container, which is a thermally insulated container having a double walled structure and being made of synthetic resin, which reduces the thermal conduction loss from the mouth portion, and which has excellent thermally insulating performance capabilities.The thermally insulated synthetic resin container 1 of the present invention has an inner container 4 and an outer container 3, which are both made of synthetic resin and which are both connected at their respective mouth portions 12, 11 while providing a space portion in between the two containers. According to this thermally insulated synthetic resin container which is formed by having the space portion between the inner container 4 and the outer container 3 be a thermally insulating layer 6, a reduced thermal conductive portion 14 having a wall of reduced thickness is formed in the vicinity of the mouth portion 12 of the inner container 4.

Abstract: A thermally insulated double-walled synthetic resin container having a thermal insulator layer filled with a low thermal conductivity gas, wherein the inner container and the outer container are formed from a chemical resistant resin, a hole portion is provided at the enter of the bottom wall of the outer container, this hole portion is sealed by a sealing panel formed from chemical resistant resin; a protrusion portion is formed on the thermal insulator layer side of the bottom central portion of the outer container and a depression portion aligned with the center of the protrusion portion is formed on the reverse side of this protrusion portion; or a metallic thin film layer is formed on the surfaces facing the thermal insulator layer aside from the area around the mouth; as a result of which the thermally insulated double-walled synthetic resin container is provided with exceptional thermal insulation capabilities and strength.

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 th

Abstract: An insulated synthetic resin container 1 is provided by forming a container having a double walled structure by integrating a synthetic resin inner container 4 and a synthetic resin outer container 3 separated by a space 5 and forming an insulating layer 6 by enclosing a gas having low thermal conductivity in space 5 of the above-mentioned container. This insulated synthetic resin container 1 comprises a gas replacement penetrating hole formed in the center of one of the synthetic resin inner container 4 and synthetic resin outer container 3; and a contact preventing projection 14 formed in the vicinity of this gas replacement penetrating hole 7 projecting into the insulating layer 6 from the surface in which this penetrating hole 7 is formed or from the opposite surface.

Abstract: A thermally-insulated double-walled container is disclosed made of synthetic resin which is formed by joining together an inner container and an outer container in a unitary fashion to form a space therebetween; wherein a thermoinsulating layer is formed in the space between the inner container and the outer container by filling the space with at least one low thermoconductive gas selected from the group consisting of xenon, krypton, and argon; and wherein the inner container and the outer container are multilayer molded from different synthetic resin materials. The container provides an excellent gas-barrier capacity without requiring plating of the outer surface of the inner container or the inner surface of the outer container in the double walled container and maintains its mechanical strength over a long period of time and having an excellent thermoinsulating capacity. The container is suitable as a thermos, cooler box, ice cooler, thermoinsulated cup, insulated lunch box, or the like.
