<p>A cup lid comprises a top (20), an annular side plate (30) and at least one buckle portion. The annular side plate (30) extends downwards from the circumferential edge of the top (20), and the buckle portion is positioned inside the annular side plate (30). The buckle portion includes a sheet (41), and a compression space (43) is formed between the sheet (41) and the annular side plate (30). The sheet (41) and the annular side plate (30) are resilient so that the sheet (41) can be compressed towards the compression space (43). When the cup lid covers on a cup body (10), the buckle lip (12) of the cup body (10) pushes and resists against the sheet (41). After the top (20) cooperates with the buckle lip (12), the sheet (41) reposits by its elasticity, and then the buckle lip (12) is clamped between the sheet (41) and the top (20) so as to enhance the combination intensity between the cup lid and cup body.</p> |
