狭くなるのが防止される。In the heat-insulating container 10 having the above-described structure, a gap is formed between the body 21 of the paper cup body 20 and the body 31 of the outer cylinder 30, and the space functions as a heat insulating member.
Moreover, since the upper end portion 26 of the paper cup body 20 adjacent to the outward curl portion 23 is bent so as to further expand outwardly over the entire circumference, voids are formed at a certain interval from below to above. Therefore, for example, when hot water is put into the heat insulating container 10, the heat of the inner body 21 is prevented from being transmitted to the outer body 31 over a wide range, and any place where such a container is usually gripped is used. Even if you grab and hold it, it will not get hot. Further, in the above example, since the reinforcing ribs composed of the circumferentially protruding portions 25 protruding outwardly are formed on the body portion 21 of the paper cup main body 20, the strength of the paper cup main body 20 is reduced by the protruding portions 25. As it rises, it serves as a support so that the body 31 of the outer cylinder 30 does not bend inward. Therefore, when held by hand, the gap between the body 21 of the paper cup body 20 and the body 31 of the outer cylinder 30 Is prevented from becoming narrow.
