THERMALLY INSULATED SYNTHETIC RESIN CONTAINER AND THERMALLY INSULATED SYNTHETIC RESIN LID

摘要

The present invention relates to a thermally insulated synthetic resin container, which is a thermally insulated container having a double walled structure an d 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 betwee n 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.
