Abstract
A method of making a cup that decreases the amount of flash on a bottom surface of the cup is provided. More specifically, a cup is provided that includes a thickened lip around an open surface. The lip also includes a recess for the receipt of excess material generated by the molding process. This excess material, or flashing, is detrimental to the use of cups in cup stacking competitions.
