Abstract: A kettle includes a kettle body, which has a spout and a support frame, a spout cap pivoted to the support frame, a handle fixedly mounted on the kettle body, a sliding grip coupled to the handle, a link coupled between the sliding grip and the spout cap, and a spring supported between the support frame and the front end of the link, such that when the user holds the sliding grip to tilt the kettle body, the sliding grip is moved relative to the handle to push the link forwards and to further open the spout cap and twist the spring; when the user returns the kettle to horizontal and releases the hand from the sliding grip, the spring automatically returns the sliding grip, causing the spout cap to close the spout again.
