Abstract
A Dispenser of fluid product includes a ring nut (2) able to be associated with a container of a fluid product and a dispensing head (7), substantially hollow and coaxially slidable relative to the ring nut. The dispensing head includes a dosing chamber (13) positioned inside the dispensing head, a dispensing nozzle (11) to allow escape of the fluid product. The dispensing head further includes a deformable membrane (14) fastened to the ring nut and a top wall (9) facing the membrane and defining the dosing chamber in combination with the membrane; the top wall being movable between a first position, distal from the ring nut, in which a volume of the dosing chamber is greatest and the dosing chamber is isolated and at least in part filled with fluid product, and a second position, proximal to the ring nut, in which the volume of the dosing chamber is smallest.
