A lid for a cup that permits cups of a variety of sizes to be securely stacked thereon. The lid has an upper surface, an exterior sidewall depending from the upper surface, and a mounting portion for sealingly engaging a first cup. The lid has an annular channel in its upper surface dimensioned to receive a bottom rim of a second cup. The annular channel has inner and outer sidewalls, with projecting lobes defining recesses on each of the inner and outer sidewalls. The bottom rim of a relatively smaller cup may be securely retained by engagement with the projecting lobes on the inner sidewall of the annular channel. The bottom rim of a relatively larger cup having a bottom rim diameter larger than that of the relatively smaller cup may be alternatively securely retained by engagement with the projecting lobes on the outer sidewall of the annular channel. |
