Abstract: An apparatus and method for dispensing an individual beverage serving are disclosed wherein a rupturable packet containing a flavoring constituent is ruptured by a mechanically actuated platen. Platen movement during the dispensing cycle is controlled by a specially configured cam and dependent upon predetermined volumes of flavoring constituent and gas within the packet. A nozzle assembly is employed for mixing the flavoring constituent with a base liquid and includes a deflector for insuring substantially uniform mixing and elimination of undesired foaming in the beverage. A specially configured rupturable packet is employed in which the side seals and the seal forming the packet spout are stronger than the peel seal of the packet, but weaker than the top closure seal. Another packet design employed with the apparatus has a spout which is angled to one side.
