Patent ID: 7997455

Claim:
A dispensing head associable to a container for obtaining a fluid dispensing device, comprising: pumping means comprising a) dispensing means that suck the fluid from the container and being actuated for dispensing the fluid outside the device, wherein the dispensing means comprise i) an enclosure delimiting a pumping chamber therein for containing the amount of fluid to be dispensed; ii) a piston for sliding in the enclosure along a dispensing axis; iii) an abutment projecting from the enclosure; b) actuating means that actuates the dispensing means; elastic return means that influences the pumping means from a dispensing configuration, wherein the chamber has a reduced volume, to a stand-by configuration, wherein the pumping chamber has a larger volume than the reduced volume, wherein the elastic return means are arranged outside the pumping chamber and comprise a) a return element, engageable with the pumping means at an active portion of the pumping means, comprising: i) a coupling portion for coupling the return element with the abutment of the pumping means; ii) an elastic portion, integral with the coupling portion and projecting therefrom along a torsion axis, wherein the torsion axis is inclined relative to the dispensing axis; iii) at least one arm, integral with the elastic portion, for the engagement with the pumping means; wherein the coupling portion of the elastic element is constrained to the abutment of the pumping means so as to prevent at least partly the stiff rotation of the elastic portion about the torsion axis, obtaining a return action on the pumping means from the dispensing configuration to the stand-by configuration.
