Description of the Related Art In general, an insulated cup made of expanded polystyrene has been used as a cup for hot drinks such as coffee, tea, milk, soup, instant noodles, and miso soup. Although the cost is low, the effects of environmental hormones and the like have recently been pointed out, and thus the cost is high, but the paper cups with high safety are being reviewed. However, paper cups are inferior in heat insulation and insufficient in strength.

A heat-insulating paper cup described in JP 1397 is known. The paper cup comprises a bottomed paper cup body having an outward curl portion at an upper opening edge, and a paper outer cylinder having upper and lower openings and an inward curl portion at a lower opening edge. The size of the paper cup body is such that the inner surface of the upper opening contacts the outer periphery of the side wall immediately below the outward curl portion of the paper cup body and the inward curl portion of the lower opening edge contacts the outer periphery of the lower side wall of the paper cup body. It is formed by covering the outer cylinder and bonding the inner surface of the upper opening of the outer cylinder to the outer periphery of the side wall immediately below the outward curl portion of the paper cup main body to integrate them together, and the gap between the paper cup main body and the outer cylinder is formed below the outer cylinder. This is characterized in that it is maximum near the inward curl portion of the opening edge, and is characterized in that the heat insulating effect is enhanced by enlarging the heat insulating gap below the cup.

【発明が解決しようとする課題】しかし、上記公知例の

を呈さない。However, the above-mentioned heat insulating paper cup of the above-mentioned known example has the following disadvantages. 1. The paper cup is hot when holding the upper part of the cup by hand, since there is almost no air gap in the upper part of the body. In particular, in the case of coffee, tea, etc., the upper part of the body of the cup is often provided due to its stability, and increasing the heat insulating effect at the lower part of the body does not make much sense. 2. Since both the cup body and the outer cylinder are straight, the strength is weak.In order to increase the strength with this structure, it is necessary to increase the thickness of the paper, which increases the cost, and also saves resources. It is not preferable from a viewpoint. 3. The cup body and the outer cylinder do not have the appearance of a single cup at the bottom.
