US Patent 8365960 Multi-compartment beverage container

A beverage container has a lower container section filled with a first liquid. Above the lower container section is an upper container section secured to the lip and groove of the lower section. The upper container section can hold a second different liquid than the first liquid. The upper section defines a mixing channel where openings to both the upper and lower container sections meet to allow the two liquids to mix prior to final dispensation.
