Abstract
A multi-flavor post-mix dispense head includes a nozzle having a plurality of concentrate inlet ports for directing concentrate(s) to a plurality of outlet ports; and a diluent inlet port for directing a diluent to an annular outlet port, surrounding the concentrate outlet ports. The annular diluent outlet port has a configuration which forms a cylindrical outlet flow of diluent surrounding a liquid stream of concentrate from any of the concentrate outlet ports. The cylindrical outlet flow of diluent combines under surface tension into a single stream to form a freely-supported cup downstream from the nozzle. The concentrates are respectively introduced through the concentrate outlet ports internally of the cup in a stream or spray to be mixed together with the diluent and then flow downstream together in a homogenous mixture.
