PROBLEM TO BE SOLVED: To provide a container molded from a metal foil, and suitable for steaming cooking.SOLUTION: Tabs 14 are connected through ruled lines 14a to an outer edge of a flange 13 of a pair of container elements 10, and one container element 10 is vertically turned over to cover the other container element 10. In a state that the flanges 13 are overlapped, the ruled lines 14a are folded to turn up the tabs 14 to an upper surface side of the flange 13. The flange 13 of the container element 10 is sandwiched and held between the flange 13 and the tab 14 of the other container element 10 from the upper side and the lower side. Since a closed space suitable for steaming cooking is formed in the inside of the overlapped container elements 10, and the container elements 10 are fixed by turning up the tabs 14, the container elements 10 do not to slip from each other even against impact and an opening is prevented from opening so as not to let steam go away. |
