Abstract: Spray nozzle comprising a front wall, an outlet channel delimited by a lateral surface substantially of revolution about an axis perpendicular to the front wall, an intake conduit supplying fluid product to the outlet channel, said intake conduit extending in a plane perpendicular to the axis, substantially tangentially to the lateral surface of the outlet channel, between an upstream and a downstream end opening out into the lateral surface of the outlet channel, the lateral surface of the outlet channel comprising a relief arranged radially relative to the axis and suitable for forming a static surface layer of fluid product.

Abstract: The invention relates to a fluid spray nozzle comprising a swirl chamber which is rotationally symmetric about a Z axis of origin O and into which at least two fluid inlet channels open. The aforementioned chamber is equipped with a discharge conduit having an axis which is inclined in relation to the axis of symmetry t an angle. According to the invention, the conduit is formed such that the position of the point of origin of the axis thereof is offset in relation the origin of the axis of symmetry by a distance which depends on the value of the angle of inclination of the conduit: along a direction which depends on the position and the cross-section of the channels, and in a sense which is counter to the orientation of the conduit.

Abstract: Dispensing member for a fluid product comprising a post and a spray nozzle, said post having an abutment surface and said spray nozzle comprising a transverse wall, an outlet orifice extending across said transverse wall, said outlet orifice being delimited by a lateral surface, at least one duct for supplying the fluid product to the outlet orifice, the said supply duct being delimited by the transverse wall and the abutment surface, being supplied with fluid product via a supply channel, emerging substantially tangentially relative to the lateral surface of the outlet orifice, and forming the only fluidic communication between the supply channel and the outlet orifice.

Abstract: Manual spraying device including a push-button that can be actuated manually, the push-button including a spray nozzle, the spray nozzle having an inner chamber adapted to receive a non-gaseous fluid product under pressure and delimited towards the outside by a perforated front wall, a reservoir for the fluid product to be sprayed, and a dispensing device that can be mechanically actuated by the push-button and adapted to transfer the fluid product from the reservoir to the inner chamber of the nozzle, the front wall having a plurality of calibrated holes, each having a diameter of between 1 and 100 ?m, the diameter of each hole not differing from a mean of the diameters of the various holes by more than 20%.

Abstract: The push-button is made up of two parts which fit into each other and define between them a whirl chamber, a part of which is formed by a cavity (38) defined inside the outer part on a face of the latter that is tilted in a direction and at a sufficient angle (?), suitable for making it possible to remove the outer part from the mould “along the axis” without damaging the cavity.
