Regarding thermal insulation containers.

``Prior Art'' Glass thermos flasks and metal thermos flasks made of stainless steel or the like are generally used as portable heat-retaining containers. These thermal containers have a double structure with a vacuum between the inner and outer bottles, making them vulnerable to external shocks. In particular, glass thermos flasks not only break when subjected to impact, but may also cause cuts, burns, etc. due to the fragments and contents. On the other hand, with metal thermos flasks, there are concerns that the outer bottle may become deformed and the heat retention ability may decrease.

As a solution to such problems, thermos containers such as thermos flasks, such as those disclosed in Japanese Utility Model Publication No. 58-30021 and Japanese Utility Model Application Publication No. 60-83334, are known.
