A lid of the present invention is used for covering a cup. The cup has a cup body and a rim flange. The rim flange surrounds upper end of the cup body. A groove is defined between the rim flange and the cup body. A horizontal distance H1 is defined between the groove and outer contour of the rim flange. The lid includes a cover plate and an engagement portion. The engagement portion is disposed on periphery of the cover plate. The engagement portion has a barb portion located on its bottom end. A tip end of the barb portion can insert into the groove. A horizontal distance H2 is defined between the tip end and outer contour of the rim flange when the lid covers the cup. The distance H2 is approximately equal to the distance H1. As such, engagement relationship between the lid and the cup is strengthened. |
