Fluid product dispensing device

A fluid dispenser device comprising:

• a dispenser member (10);
• a fluid reservoir (30);
• a fastener element (20) for fastening said dispenser member (10) onto a neck (35) of said reservoir (30);
• and
• a turret (40) disposed between a body (11) of the dispenser member (10) and said fastener element (20),
• wherein said turret (40) includes a deformable radial flange (45), said deformable radial flange having deformable sealing projections (46, 47) that extend upwards from said radial flange (45), wherein said radial flange (45), before assembly, curves upwards, and after assembly, has a deformed flattened shape which co-operates in a leaktight manner with the top edge of the neck (35) of the reservoir (30) so that said radial flange (45) is in contact with the fastener element (20) and the neck (35) of the reservoir (30), and said sealing projections (46, 47), after assembly, are also deformed and co-operate in a leaktight manner with said fastener element (20),
• wherein the deformable radial flange (45) of the turret (40) forms at least one sealing zone with the top edge of the neck (35) of the reservoir (30), and said sealing projections form two sealing zones with the fastener element (20),
• wherein the deformable sealing projections (46, 47) extend, before assembly, axially and parallel to each other,
• wherein the fastener element (20) includes an approximately cone-shaped profile (25), and after assembly, the two projections (46, 47) co-operate in leaktight manner with the approximately cone-shaped profile (25), the tip of the cone being disposed between the two projections (46, 47).
