13. A fluid product dispenser comprising:
a fluid product reservoir having a neck (1) internally defining an axial opening (10) oriented upward and communicating with the inside of the reservoir (R),
a dispensing head (T) mounted axially on the neck (1) of the reservoir (R), the head (T) comprising a dispensing member (P) and a fastening ring (F) engaging both the neck (1) of the reservoir (R) and the dispensing member (P), the fastening ring (F) comprising a skirt (2) including a plurality of internal latching projections (211),
wherein the neck (1) defines externally a plurality of horizontal latching shoulders (130) oriented downward and a plurality of release ramps (112), the latching projections (211), initially engaged below the horizontal latching shoulders (130), being constrained radially outward on the release ramps (112) by rotation of the skirt (2) around the neck (1), thus releasing the latching projections (211) of their latching engagement from below the latching shoulders;
wherein the neck (1) externally defines a cylindrical base zone (11) and a plurality of projecting supports (12) separated from one another by the cylindrical base zone (11), except at projecting ribs (13), each projecting support (12) forming a projecting zone (121), a vertical release ramp (112) and advantageously at least one oblique cam of angular indexing (123) which connects the cylindrical base zone (11) to the projecting zone (121) and advantageously an oblique unscrewing cam (125) which projects from the projecting zone (121), each projecting rib (13) forming one of the plurality of the horizontal latching shoulders (130) and a radial expansion ramp (133), and
wherein the skirt (2) comprises a base cylindrical external face (20), the skirt (2) comprising latching tabs (21) which form the latching projections (211) coming below the latching shoulders (130), each internal latching projection (211) defining two vertical lateral edges (214), as well as a tip-shaped free end (215), the skirt (2) also comprising axial holding tabs (22) coming into close and extended contact with the projecting zones (121) of the neck (1), the latching tabs (21) and the axial holding tabs (22) being disposed alternately by being separated by vertical slots(S), the latching tabs (21) defining free external faces (217) which are offset radially inward with respect to the base cylindrical external face (20), while the axial holding tabs (22) define external contact faces (227) which are aligned and continuous with the base cylindrical external face (20), the axial holding tabs (22) each advantageously forming a lower gap (221) housing the unscrewing cam (125) of the neck (1), and a trim band (3) engaging the external contact faces (227) of the axial holding tabs (22).
