  • the preferred fields of application of the present invention are those of perfumery, cosmetics or even pharmacy.
  • the document US4273290 describes another fluid product dispensing module integrated into a dispensing head. More precisely, this distribution module is in the form of a nozzle comprising a chamber and swirl channels, as well as a valve in the form of a disc biased by a spring. The fluid under pressure pushes the disc back against the spring, so that the fluid can flow inside the nozzle to reach the channels and the swirl chamber before exiting in a spray manner through an orifice of distribution.
  • the fluid product distribution module defines a fluid product flow path which extends from an inlet of the distribution module to a distribution orifice.

  • the movable member comprises two piston lips which slide in a sealed manner in a sliding barrel which forms the two lateral openings, the two piston lips closing off the two lateral openings in the rest position.
  • the movable member comes into sealed abutment in the rest position under the action of the spring against a radial shoulder of the fluid flow path. A double seal is thus guaranteed at the level of the fluid flow path.
