Can be prevented. That is, for example, the inner container 57 does not rotate in the outer container 56 held by hand while the food A in the inner container 57 is being eaten.

  In any of the above-described embodiments, the leg portions 17 and 67 are not limited to those having the plurality of leg plates 18 and 68. For example, the leg portions 17 and 67 have substantially cylindrical cylindrical legs. The thing etc. which penetrated the opening part for hot ventilation to the inner peripheral surface may be used.

  Further, the lids 3 and 53 are not limited to those mounted and mounted on the upper end portions of the container main bodies 2 and 52. For example, the lid bodies 3 and 53 may be fitted on the upper end portions of the container main bodies 2 and 52, etc. It may be one that is attached to and detached from the container main bodies 2 and 52 by rotation.

Further, the air layer maintaining part that maintains the air layers 8 and 58 uniformly over the entire circumference of the container main bodies 2 and 52 is, for example, the outer side surface (outside the lower end part) of the middle part in the vertical direction of the side plate parts 24 and 74 of the inner containers 7 and 57. A ring-shaped convex portion projecting on the side surface) or an annular convex portion projecting on the inner side surface of the upper side of the side plates 14 and 64 of the outer containers 6 and 56 (the outer surface in the middle in the vertical direction and the inner surface of the lower end). Further, it may be formed of a plurality of convex portions instead of an annular shape .

  On the other hand, the outer container 56 is not limited to the configuration having the convex portion 69 and the inner container 57 has the concave portion 79. For example, the outer container 56 has a concave portion that is a concave one side engaging portion, and the inner container 57 The structure etc. which have a convex part which is a convex one side engaging part may be sufficient.
