摘要

PROBLEM TO BE SOLVED: To provide a container which can be kept warm for many hours with a power source such as a battery by attaching a heater to the bottom of the container or the like in order to solve the problem that a conventional heat insulating container is heat insulated employing a heat insulating material or the like and the effect is reduced in a short time. ;SOLUTION: A thing contained in a container body (1) is kept warm by heating of a heater attached to the bottom of a container body (1) or the like with a power source (3) such as a battery by attaching a heater to the bottom of the container body (1) or the like.
