Therefore, when hot foods such as hot drinks and hot soups are contained, since the food containers themselves do not have a heat insulating effect, the hot air of the hot foods is directly In addition to the opening, it is more fully transmitted to the food container as a whole and diverges outward. Therefore, when the user holds the food container by hand, the portion in contact with the food container is liable to be burnt by the hot air.
