1. A fluid dispenser member having a dispensing wall defining an outside surface and inside surface, said wall being provided with a through dispensing orifice connecting the inside surface to the outside surface, the inside surface forming a leaktight slide cylinder for a piston suitable for moving in leaktight contact inside said cylinder for selectively unmasking the dispensing orifice, said piston forming a wall element of a fluid chamber inside which fluid is selectively put under pressure; the inside surface, at the slide cylinder, forming a fluid swirl system immediately upstream from the dispensing orifice, wherein the dispensing wall is formed by a substantially cylindrical skirt further provided with a guide wall defining an inside surface whose inside diameter is greater than the inside diameter of the slide cylinder; and wherein the slide cylinder, the dispensing orifice and the swirl system are formed integrally with the dispensing wall.
