US Patent 11345583 Inserts and nozzle assemblies for beverage dispensers

An insert for use with a beverage dispenser includes a diffuser having an upstream end configured to receive the first base fluid, a downstream end with an outlet configured to dispense the first base fluid, and a center bore extending between the upstream end and the downstream end along an axis. A stem is disposed in the center bore of the diffuser and has a first end configured to receive a second base fluid and an opposite second end with an outlet configured to dispense the second base fluid. The outlet of the diffuser is upstream from the outlet of the stem such that the first base fluid dispensed from the outlet of the diffuser mixes with an additive fluid before the second base fluid dispensed from the outlet of the stem mixes with the additive fluid.
