<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> |
