Abstract: A cover for a cup, the cover comprising a cap and a lid, with the cap mountable on a cup, with the lid rotatably attached to the cap and with the cap and lid having openings for fluid flow from the cup when the openings are in alignment. The cap-lid attachment includes a first ring on the cap and a second ring on the lid, with the second ring rotating within the first ring, and with the second ring having resilient fingers projecting from the second ring past the first ring, with outwardly projecting hooks at the end of the fingers for latching the rings together. The first ring has projecting stops for engagement by the second ring hooks for limiting rotation of the lid between aligned and non-aligned positions of the openings, with the cap and lid having bands with openings therein, with the lid band overlying the cap band, and with the cap band having a rib around the cap openings and in sealing engagement with the lid band.
