Drinking, the lower outer peripheral portion is formed with a step groove 16 is the middle cup 20 is detachably screwed. In addition, the inner cup 10 is preferably formed of a glass material so as to feel a good drinking feeling.

The middle cup 20 contacts the lower outer periphery and the bottom of the inner cup 10 to transfer the latent heat of the refrigerant R to the inner cup 10, and the middle cup 20 rapidly transfers the latent heat of the refrigerant R. It is preferable to be made of a brass material having excellent thermal conductivity so as to transmit, but may alternatively be made of another thermal conductor having excellent thermal conductivity.

Thus, the middle cup 20 made of brass is formed in a cylindrical shape to surround the lower outer periphery of the inner cup 10 and is detachably screwed to the step groove 16, and the partition plate 22 at the center of the middle cup 20. It is formed integrally with the bottom surface of the inner cup 10 is provided with a receiving space 24 which is open at the bottom. Accordingly, the body surface area in which the middle cup 20 transferring latent heat of the refrigerant R contacts the inner cup 10 is widened, thereby maximizing cooling efficiency.

In addition, the middle cup 20 is formed so that the gap retaining ring 26 protrudes along the lower outer circumferential surface, thereby maintaining the gap of the air insulation layer (A) formed between the outer cup (30). The middle cup 20 in contact with the outer cup 30 by the air insulation layer A minimizes the body surface area in contact with the outer cup 30, so that the latent heat of the refrigerant R is lost by being moved to the outer cup 30.
