Claims

[Claims for Utility Model Registration] 1. Consisting of an insulated outer container made of metal that insulates the gap between the inner cylinder and the outer cylinder, and an inner container that is removably inserted into the insulated outer container, A circumferential engaging portion is formed on the body to be supported by the mouth of the insulated outer container, and when the inner container is inserted into the insulated outer container, the inner cylinder of the insulated outer container and the inner container are inserted. A heat-retaining container characterized by being able to define an air insulation layer between the parts. 2. The heat-retaining container according to claim 1, wherein the inner container is made of a material having low thermal conductivity and stable chemical properties, such as heat-resistant glass, ceramics, china, or heat-resistant plastic. 3. The heat-insulating container according to claim 1 or 2, characterized in that a holding member is interposed between the inner cylinder of the heat-insulating outer container and the inserted portion of the inner container to resiliently hold both containers. 4. Claim 1, characterized in that a thread is formed on one of the inner cylinder of the heat-insulating outer container and the inserted portion of the inner container, and a thread that engages with the thread is formed on the other.
Or the thermal container described in 2.
