<p>PROBLEM TO BE SOLVED: To provide a container with excellent heat insulation which is difficult to transfer the heat of the content even when any part of a body part is held by hand. SOLUTION: A heat-insulated container comprises a paper cup body 2 having an outwardly curled part 6 on an upper opening edge and a paper outer cylinder 3 with upper and lower parts opened and having an inwardly curled part 8 on a lower opening edge, and a plurality of circular inwardly recessed parts 9 are continuously arranged in the circumferential direction in the vicinity of an upper part of a body part of the outer cylinder 3. The outer cylinder 3 is housed over the paper cup body 2, an inner side surface of the circular recessed part 9 of the outer cylinder 3 is integrally adhered to an outer circumferential surface of the side wall close to an upper part of a body part of the paper cup body 2, and a gap 10 is formed between the paper cup body 2 and the outer cylinder 3. Since the gap 10 for heat insulation is formed with specified intervals from a lower part to the circular recessed part 9 of the outer cylinder 3, the heat of the content is difficult to transfer even when any part of the body part is held by hand.</p> |
