An easy-to-open bottle cap comprises a bottle cap main body (1), a pull ring (2), and a connecting plate (11). One end of the connecting plate (11) is connected to the pull ring (2), and the other end is connected to a side edge (3) of the bottle cap main body (1). An outer edge (4) of the pull ring (2) is circular, and an inner edge (5) is circular or elliptic. A circle center of the outer edge (4) of the pull ring and a circle center of the inner edge (5) of the pull ring are at a same position. A radius of the outer edge (4) of the pull ring is greater than a radius of the inner edge (5) of the pull ring. A concave area (6) is disposed on an end surface of the bottle cap main body (1) to accommodate the pull ring (2). The bottle cap main body (1), the pull ring (2), and the concave area (6) are a whole, and no component is added in an externally connecting manner. When the pull ring (2) is superposed with the concave area (6), the pull ring (2) and the end surface of the bottle cap main body (1) are located on the same horizontal plane, and no convex part is formed on an end surface of the bottle cap, thereby facilitating industrial mass production. |
