A spray nozzle for a system for dispensing a pressurized product is provided with a pushbutton. The nozzle includes a dispensing orifice and a vortex chamber emerging on the dispensing orifice. The chamber includes a conical part defined by a conical side surface. The conical side surface converges from an upstream end toward a downstream supply end of the dispensing orifice. The nozzle further includes at least one supply channel of the vortex chamber, each supply channel emerging in the upstream end of the conical part, the conical side surface having at least one stepped portion provided with multiple levels.

A pushbutton for a system for dispensing a pressurized substance, the pushbutton including a body having a housing provided with an anvil around which a spray nozzle is mounted so as to form a substance dispensing path between the housing and a swirl array including a swirl chamber provided with a dispensing port as well as at least one supply duct for the chamber, the swirl chamber being defined by a side surface having a frusto-conical shape relative to which the supply duct(s) extend(s) in a transverse plane, the side surface tapering from an upstream end into which the downstream end of the supply duct(s) tangentially extends, to a downstream supply opening of the dispensing port, the dispensing port having an outlet size that is equal to the internal size of the downstream opening.

Push-button for a system for dispensing a product under pressure

A push-button for a dispensing system for a liquid under pressure, the push-button includes a body having a mounting well on a delivery tube for the liquid under pressure and a housing in communication with the well, the housing being provided with an anvil around which a spraying nozzle is mounted in such a way as to form a dispensing path of the fluid between the housing and a vortex unit including a vortex chamber provided with a dispensing orifice as well as at least one supply channel of the chamber, the nozzle having a proximal wall wherein is formed a print of the vortex unit and the anvil having a distal wall whereon the proximal wall of the nozzle is pressing against in order to delimit the vortex unit between them, the distal wall having a recess which is formed across from the print of the vortex chamber, the maximum depth of the recess being between 25% and 300% of the minimum depth of the print of the supply channels.

Push-button for a system for dispensing a liquid under pressure

A push-button for a pressurised liquid distribution system, the push-button including a body onto which an end piece is mounted around an insert so as to form a distribution chamber between said end piece and the insert, the distribution chamber being in communication with a supply channel intended to be mounted on a feed tube for the pressurised liquid, the distribution chamber being successively connected to upstream channels, downstream channels and distribution channels, the distribution channels each converging towards an outlet opening while being designed to enable the impaction of the liquid jets dispensed by the openings, the upstream and downstream channels extending longitudinally while forming an upstream and downstream fluid flow section, respectively, in the distribution chamber, the downstream section having an average transverse surface which is less than the average transverse surface of the upstream section.

Push-button for a pressurized liquid distribution system

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.

A push-button for a pressurized product dispensing system, including a body having a mounting shaft on a pressurized product supply tube and a housing equipped with a passage for dispensing the product between the shaft and a swirl assembly including a swirl chamber provided with a dispensing aperture as well as at least one supply channel for the chamber, in which the push-button also includes a needle movably mounted in the housing between a position closing the supply of the dispensing aperture and a position opening the supply; the needle has an actuation bearing in communication with the dispensing passage so as to enable the movement of the needle into the opening position; the needle has a distal wall arranged opposite the dispensing aperture so as to form the base of the swirl chamber when the needle is in the opening position, and the distal wall has a recess.

Push-button for a pressurized product dispensing system

A spray nozzle designed to be mounted in a push button of a liquid distribution system, including a body equipped with an assembly tube that is defined by a front wall in which a distribution orifice is formed, wherein the inside face of the front wall is equipped with a vortex chamber that communicates with the distribution orifice, at least two radial tubes to supply liquid to the vortex chamber, and an annular duct to supply liquid to the upstream end of the tubes, in which the lateral inside wall of the tube is equipped with at least two axial grooves which respectively extend between an upstream end opening onto the rear edge of the tube and a downstream end opening onto the annular duct, wherein the grooves are positioned angularly so that each downstream end of a groove is equidistant from the two upstream ends of the tube adjacent to it on either side along the length of the annular duct.

Spray nozzle comprising axial grooves to provide a balance supply to the vortex chamber

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.

Dispensing member for a fluid product, dispenser comprising such a dispensing member and use of such a dispensing member

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 &#x3bc;m, the diameter of each hole not differing from a mean of the diameters of the various holes by more than 20%.

Spraying device and use of this device

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 (&#x221d;), suitable for making it possible to remove the outer part from the mould 'along the axis' without damaging the cavity.
