As a lunch box, for example, actual fair 4-4992
As disclosed in Japanese Patent Application Publication No. 8 (1996) -1994, there is an apparatus having a vacuum double structure including an inner body and an outer body forming a vacuum heat insulating space between the inner body.
【０００３】しかしながら、この種のランチボックスで

別途、プラスチック製の内容器を必要としていた。この
ため、ランチボックス自体が大型化し、携帯に適さない
という問題があった。However, in this type of lunch box, food (mainly rice and rice) is not directly stored in the inner trunk,
Separately, a plastic inner container was required. For this reason, there was a problem that the lunch box itself became large and was not suitable for carrying.
【０００４】また、前記内容器の蓋は二重構造になって
いるものの、ランチボックスの蓋は複数段に重ねた内容
器を覆うだけのものであり、保温性の点で不十分であ
る。Further, although the lid of the inner container has a double structure, the lid of the lunch box only covers the inner container stacked in a plurality of stages, which is insufficient in terms of heat insulation.

着脱が困難となる。[0006] However, in such a heat insulating structure of the lid, since the inner plug and the lid, which are heat insulating members, are provided separately, for example, when eating food stored in the container body, once After removing the lid and placing it in a suitable place, it is necessary to remove the inner plug, which is inconvenient to handle. In addition, since a space is formed between the upper surface of the inner plug and the lid, if the user carries the inner plug, the inner plug may move upward due to vibration, and the stored food (especially, liquid food) may be spilled. is there. Therefore, when used as a portable, it is necessary to press-fit the inner plug into the base,
It becomes difficult to attach and detach.
