Abstract
A spray head for a fluid dispenser device, having a body with an expulsion channel terminated by a dispenser orifice, an insert in the expulsion channel, the end of the insert is co-operates with the downstream end portion of the expulsion channel to define a spray profile. The insert includes an elastically-deformable portion adapted to deform to absorb and/or compensate for variations in the dimensions of the body and/or insert, and/or to compensate for deformations and/or movements of the insert. The elastically-deformable portion of the insert has tabs that are axially and/or radially deformable, and/or an overmolded portion made of deformable material, and/or one or more radial openings that pass through the insert, and/or at least one sloping strip of deformable material.
