Abstract
The invention provides a drink mixing cup for fluids comprising an outer chamber having an outer rim disposed at its top and a chamber disposed inside the outer chamber having an inner rim disposed below the outer rim by an amount selected to optimize mixing fluids poured from said chambers when drunk by humans. The design allows for nesting of cups and thermal insulation of the inner chamber. An advantageous method of delivering mixed drinks to patrons can be obtained using one or more cups having an outer chamber and an inner chamber and having a space below the inner chamber disposed inside said outer chamber and a tray having mandrels having a shape corresponding to the space below the inner chamber, whereby the cups can be mounted on the mandrels and prevented from sliding off the tray when tipped.
