The dispenser nozzle consists of a dosing chamber (30) with an inner sliding spring-loaded piston (21) which has one surface (31) in communication with the product in a container and a second surface (25) in communication with the dosing chamber. The dispenser nozzle consists of a dosing chamber (30) with an inner sliding spring-loaded piston (21) which has one surface (31) in communication with the product in a container and a second surface (25) in communication with the dosing chamber. The piston is able to slide between one position in which the chamber is at maximum volume and a second position where it is at minimum volume. The chamber has an inlet (12) which is open when the piston is in the first position and closed when in the second, while a recess (27) in the outer wall of the piston dispenses the product from the chamber
