Abstract: A beverage container for use with a drinking cup for dividing the cup into at least two individual beverage containing cells, each of which forms a discrete beverage container separate from the other. The beverage container comprises a semi-cylindrical, vertically tapered device, sized and shaped for mating insertion into a conventional tapered drinking cup. The beverage container includes a side wall having a top rim forming an opening, and a bottom. The side wall includes a curved, vertically tapered first side wall portion and a generally planar, vertically tapered second side wall portion. An elongated flexible tab is connected on one end thereof along a curved portion of the beverage container rim and folds over the rim of the cup upon insertion. The tab includes indicia for identifying the particular type, flavor, or brand of beverage contained within the beverage container portion of the drinking cup.
