An adaptor is provided for a cup having side walls tapered along a length of the cup. The cup has a bead around an open top of the cup. The adaptor includes a cap with a spout having openings in fluid communication with an inside of the cap. An annular base depends from the cap and has threads that engage the side walls of the cup to hold the cup to the adaptor. The base has a recess sized to engage the bead of the cup and seal the opening of the cup. Handles fasten to the adaptor for easier gripping.
