<p>Disclosed are a bottle cap, and more particularly, a bottle cap for improving cooling of a bottle made of a material having low heat conductivity, such as a PET bottle, and a cooling method using the bottle cap. The bottle cap comprises a heat conduction rod protruded from the lower surface of an upper portion thereof, an ornamental portion formed on the lower end of the heat conduction rod, and a lid covering the upper portion and made of a material having low heat conductivity. The cooling method using the bottle cap effectively transfers coldness of a refrigerator to the contents of the bottle through the heat conduction rod made of a material having higher heat conductivity than that of the bottle, and causes the bottle cap to directly contact a refrigerant pipe of the refrigerator, thereby increasing cooling effects.</p> |
