Abstract: Fluid product dispenser comprising: a reservoir (R) having a neck (1), a dispensing head (T) mounted axially on the neck (1) and comprising a dispensing member (P), and a fastening ring (F) engaging both the neck (1) and the dispensing member (P), the fastening ring (F) comprising a skirt (2) including a plurality of internal latching projections (211), characterised in that 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 (130).

Abstract: A fluid product dispenser comprising: a reservoir (R) having a neck (1) defining at least one horizontal latching shoulder (1), a dispensing head (T) mounted on the neck (1) and comprising a dispensing member (P), and a fastening ring (F) engaging both the neck (1) and the dispensing member (P), the fastening ring (F) comprising a skirt (2) comprising at least one internal latching projection (21) that is received below said at least one horizontal latching shoulder (121), characterised in that said at least one horizontal latching shoulder (121) is formed on an oval base (11) of the neck (1) that has an oval outer wall (110) with a horizontal cross-section of generally oval shape, except at said at least one horizontal latching shoulder (121).
