<p>A dispenser mechanism (1) for a foamed product comprises a liquid chamber (9) and air chamber (10), each compressed by a common actuator mechanism (6a, 6b), wherein the liquid and air simultaneously enter a foaming chamber (15). The liquid is forced through a diffuser (18a) defining a plurality of distributed channels (18e), each channel (18e) having a predetermined cross section such that in use the liquid is forced through the channels and enters the foaming chamber as a plurality of jets. The dispenser mechanism (1) provides a particularly advantageous arrangement for producing foam and may be arranged to prevent the foam dripping from an outlet after the end of a dispensing cycle.</p> |
