The present invention discloses a cup support and a dispensing device that uses a cup support. The cup support is adapted to hold at least cups of two different diameters and sizes. The cup support and the dispensing device are adapted to detect the diameter and size of the cup, and enable that when a diluent jet is injected into the cup, the jet is oriented to impact onto a predetermined position on a sidewall of the cup. The orientation of the jet achieves an effective dissolution of food ingredient in the cup by the injected diluent. The dispensing device is designed to move the cup support in a horizontal and vertical direction, to rotate the cup support. The cup support is not directly actuated, but is fitted into movable and rotatable holding means, from which it can be easily dismantled to be cleaned. The cup support comprises a plug element comprising one protusion. The dispensing device comprises a motor for vertically moving the cup support or the injection means.
