PROBLEM TO BE SOLVED: To provide a vacuum double container for keeping soup warm hardly slipping off, being easily held and being capable of reducing the possibility that heat retaining properties will be impaired even in the case where an outer cylinder is dented due to impact caused by falling down thereof or the like.SOLUTION: A vacuum double container for keeping soup warm 100 comprises: an inner cylinder portion 111; an outer cylinder portion 112; and a vacuum space SP. The inner cylinder portion has a bottom portion 111b. The outer cylinder portion 112 has a side wall portion 112a, a bottom wall portion 112b and an overhang portion 112e. The overhang portion 112e overhangs closer toward an outside than the side wall portion. Further, the outer cylinder portion is joined to an opening end portion of the inner cylinder portion at an opening end portion. The vacuum space is formed between the outer cylinder portion and the inner cylinder portion. In addition, it is preferable that the inner cylinder portion be formed of a material more excellent in corrosion resistance than a formation material of the outer cylinder portion.SELECTED DRAWING: Figure 2 |
