The open end has an edge bent outward to form a flange. The ring is securely mounted around an outer periphery of the body and has two open ends. The sleeve is mounted around the ring and includes upper and lower open ends. The upper open end of the sleeve abuts a bottom of the flange of the body. A heat-insulating space is provided between the sleeve and the body to effectively avoid a hand of a user from high heat.
