<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 are simultaneously forced into a foaming chamber (15, 22). The foaming chamber comprises at least one fin element (17) separating open portion (15) and closed portion (22) of the foaming chamber, with the liquid being forced from the closed portion (15) past the tip of the fin (17) into open portion (22) through which the air is flowing, where the liquid mixes with the air and forms a foam. 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> |
