A lid assembly of the present invention is used for clipping a rim flange of a cup. The lid assembly includes a lower member and an upper member. The lower member has a top clipping surface and several barbs. The upper member has a bottom clipping surface and at least a barb portion corresponding to the barbs. The barb portion is able to engage with the barbs. As such, the rim flange can be clipped between the top clipping surface and the bottom clipping surface. Therefore, the lid assembly can be firmly assembled on a cup by clipping the rim flange, even though the specification of the cup is slightly changed. Moreover, the lid assembly can not be detached unpredictably. |
