PURPOSE:To easily form a linear thin-walled part by cutting a notch in a plastic sheet to perform the vacuum molding of the notched sheet to form a body part having the shape of a round mirror-shaped rice cake having constrictions in the vicinity of the center and lower end thereof. CONSTITUTION:A container 1 for a round mirror-shaped rice cake equipped with a container body part 3 having the shape of the round mirror-shaped rice cake provided with a linear thin-walled part 6 and the plastic bottom sheet 4 hermetically sealing the container body part 3 is prepared. At this time, a notch is cut in a plastic sheet and, subsequently, the notched sheet is subjected to vacuum molding to form the linear thin-walled part 6. By this method, the container 1 of the round mirror-shaped rice cake can be efficiently prepared. |
