(Effects of the invention) According to the invention, both ends of the suspension band are fixed to the end fixing parts integrally formed with the bottom member which is force-fitted from below to the outer periphery of the bottom of the metal double container. When a portable thermal container is carried by a hanging band, the load of the metal double container is received by the hanging band through the bottom member, and the weight of the metal vacuum double container and the hanging band are Suspension by means of suspension works to connect the metal vacuum double container and the synthetic resin bottom member to each other, but it does not work to separate the double container, the synthetic resin shoulder member, and the bottom member from each other. It is possible to avoid such a situation that the hanging band is attached to the upper outer periphery of the metal vacuum double container by force-fitting it from above to the holding part that penetrates vertically and is integrally formed with the shoulder member. Since the hanging band is passed through from above, it does not apply any load to the holding part when hanging the portable thermal container, so it can be force-fitted to the metal vacuum double container from above and below. There is no possibility that the shoulder member and the bottom member to be worn will be separated or loosened and cause wobbling due to carrying with a hanging band.

In addition, the holding part prevents the hanging band from swinging between the portable heat-insulating container and the portable heat-insulating container at two opposing locations on the top of the portable heat-insulating container, thereby stabilizing the hanging posture of the portable heat-insulating container vertically. This makes it convenient to carry the portable thermal container, and this prevention of swinging ensures that the hanging force by the hanging band acts correctly on the bottom member in the axial direction of the metal vacuum double container. It also helps to prevent the separation and wobbling, and the overall structure is robust, easy to handle, and easy to use.
