    Spray nozzle, in particular for a dispensing system of a pressurized product provided with a push button, and dispensing system comprising such a nozzle. The invention relates to a spray nozzle for a receptacle, in particular for a dispensing system of a pressurized product provided with a push button. The invention also relates to a dispensing system comprising such a nozzle.
    In a particular application, the dispensing system is intended to equip bottles used in perfumery, in cosmetics or for pharmaceutical treatments. Indeed, this type of bottle contains a product which is returned by the dispensing system comprising a device for sampling under pressure of said product, said system being actuated for example by a push button to allow the product to be sprayed. In general, the sampling device comprises a pump or a manually operated valve, for example by means of the push button.
    Such push buttons are conventionally made of at least two parts, including an actuating body and a spray nozzle which are assembled to one another. The nozzle generally comprises a swirl chamber provided with a dispensing orifice, as well as at least one supply channel of said chamber.
    The sampling device takes the product from the bottle by a tube, and pushes it under pressure inside the duct arranged in the pusher, which is the operating element of the sampling device. This conduit opens into a so-called vortex chamber for rotating the liquid very quickly and thus to give it speed and the effects of centrifugal force. This vortex chamber is extended in its center by an outlet port through which the product escapes to the outside with a high speed. Moved by this speed, and subjected to centrifugal forces, the liquid splits into droplets and forms an aerosol. The size of the droplets from the vortex chamber depends in part on the force and speed with which the user actuates the pump by pressing the push button with his finger, as the induced pressure depends on it.
    In order to ensure a good uniformity of the size of said droplets, a technology consists in using a conical swirl chamber. Thus, the stream rotates in the chamber in the form of a sheet which impinges on itself after its exit through the dispensing orifice.
    Document FR2952360 shows an example of such a conical swirl chamber. Here, the supply channels open tangentially in the vortex chamber, which is cylindrical of revolution to rotate the product very quickly. In addition, the dispensing orifice has a reduced diameter relative to that of said chamber so that the rotating product escapes through said orifice by impinging on itself with a speed sufficient to split into droplets forming the fluid. 'aerosol.
    However, this technology has limited effectiveness for fluids whose viscosity is close to that of water. When the products to be sprayed have higher viscosities, for example up to 50 or 100 times that of water, the impaction is low and the restitution is in the form of a hollow cone spray or jet . Thus, droplets of the desired size are not obtained. The invention aims to solve this problem and aims to provide a spray nozzle for a dispensing system capable of spraying products whose viscosity is greater than that of water, so as to obtain droplets consistent with the size desired for bottles of perfumery, cosmetics or pharmaceutical treatments. To this end, the invention relates to a spray nozzle, in particular for a dispensing system of a pressurized product provided with a push button, the nozzle comprising a dispensing orifice and a swirl chamber opening on the dispensing orifice. the chamber having a conical portion delimited by a conical side surface, said conical side surface converging from an upstream end to a downstream feed end of the dispensing orifice, the nozzle further comprising at least one feed channel said vortex chamber, the supply channel or channels opening at the upstream end of the conical portion, the conical side surface having at least one stepped portion provided with a plurality of levels.
    The stepped portions promote greater impaction of the sheet on itself, and thus the formation of sufficiently fine droplets. Indeed, when the fluid turns in the form of a laminar layer on the surface of the conical portion and approaches the outlet orifice, the sheet jumps from one stage to the other between two levels, which causes turbulence of its flow. Thus, we manage to create a significant turbulence despite the viscosity of the product.

The invention also relates to a system for dispensing a product under pressure for a receptacle, in particular a bottle of cosmetic product, the system comprising such a spray nozzle. The dispensing system preferably comprises a push button arranged to carry the spray nozzle. The invention will be better understood in the light of the following description which is given for information only and which is not intended to limit it, accompanied by the accompanying drawings: FIG. 1 schematically illustrating a sectional view of the top of a container provided with a dispensing system according to a first embodiment of the invention, - Figure 2 schematically illustrating an enlarged sectional view of a push button of the dispensing system.

    In Figure 1, there is shown a cosmetic product bottle comprising a system for dispensing a product under pressure according to a first embodiment. The dispensing system has a push button. The push button comprises a body 1 having an annular skirt 2 surrounding a well 3 for mounting the push button on a feed tube 4 of the pressurized product. Furthermore, the push button comprises an upper zone 5 allowing the user to exert a digital support on said push button in order to move it axially.
    The dispensing system comprises a sampling device 6 equipped with a tube 4 for supplying the pressurized product which is sealingly inserted into the well 3. In a known manner, the dispensing system also comprises mounting means 7 on a bottle 8 containing the product and 9 product sampling means inside said bottle which are arranged to supply the feed tube 4 in pressurized product. The sampling device 6 here comprises a manually operated pump or, in the case where the product is packaged under pressure in the bottle 8, a manually operated valve. Thus, during a manual movement of the push button, the pump or the valve is actuated to supply the supply tube 4 with pressure product. The mounting means 7 comprise, for example, a fixing ring and a decorative hoop for hiding the ring and the feed tube 4.
    As shown in Figure 2, the body 1 also has an annular housing 10 which is in communication with the well 3. In the embodiment shown, the housing 10 has an axis perpendicular to that of the mounting well 3 to allow a lateral spray of the product relative to the body 1 of the push button. In a variant that is not shown, the housing 10 may be collinear with the well 3, in particular for a push button forming a nasal spray tip.
    The housing 10 is provided with an anvil 11 around which a spray nozzle 12 is mounted so as to form a distribution path of the product under pressure between said housing and a vortex chamber. To do this, the anvil 11 extends from the bottom of the housing 10 leaving a channel 13 for communication between the well 3 and said housing.
    In the embodiment shown, the distribution path has successively in communication from upstream to downstream: an upstream annular conduit 18 in communication with the channel 13, said tubular conduit 18 being formed between the inner face of the side wall 14 of the nozzle 12 and the outer face of the side wall of the anvil 11 which is arranged opposite; a downstream annular duct 21 formed between the proximal wall 15 of the nozzle 12 and the distal wall 17 of the anvil 11. On the downstream side, the dispensing path supplies pressurized product to the vortex chamber 22, provided with at least one 24 supply channel of said chamber. More specifically, in the embodiment shown, the supply channels 24 communicate with the downstream annular duct 21. In the embodiment shown, the nozzle has two channels 24 supplying the vortex chamber 22, said channels being arranged symmetrically with respect to the distribution axis D. In a variant, more than two supply channels 24 may be provided, in particular three channels 24 arranged symmetrically with respect to the distribution axis D, or a single channel 24 may be provided to supply the vortex chamber 22. The combination of the nozzle 12 in the housing 10 is formed by fitting of the outer face of the side wall 14, the rear edge of said outer face being further provided with a radial projection 16 of anchoring the nozzle 12 in said housing. Furthermore, an impression of the vortex chamber is hollowed out in the proximal wall 15 and the anvil 11 has a flat distal wall 17 on which the proximal wall 15 of the nozzle 12 bears to delimit between them the vortex assembly. . The nozzle 12 is further provided with a dispensing orifice 23 through which the product is sprayed.
    Advantageously, the nozzle 12 and the body 1 are made by molding, in particular of a different thermoplastic material. In addition, the material forming the nozzle 12 has a stiffness that is greater than the stiffness of the material forming the body 1. Thus, the significant stiffness of the nozzle 12 prevents its deformation during its mounting in the housing 10 so to guarantee the geometry of the vortex chamber. In addition, the lower stiffness of the body 1 allows improved sealing between the mounting well 3 and the feed tube 4. In an exemplary embodiment, the body 1 is made of polyolefin and the nozzle 12 is made of cyclo copolymer olefinic (COC), poly (oxymethylene) or poly (butylene terephthalate).
    In the embodiment shown in FIGS. 3 to 5, the vortex chamber 22 comprises a cylindrical part 30 into which the downstream end of the supply channels 24 opens tangentially, the cylindrical portion being delimited by a cylindrical lateral surface 34 of revolution. , which is closed forwardly by a proximal wall 35. The swirl chamber 22 further comprises a conical portion 31 downstream of the cylindrical portion 30. The conical portion 31 is delimited by a lateral surface 25 which extends along a distribution axis D, the distribution channels 24 extending in a plane transverse to said distribution axis D. In the description, the terms of positioning in space are defined with respect to the distribution axis D. In the embodiment shown, the lateral surface 25 is of revolution about the distribution axis D. The lateral surface 25 is convergent from an extremity 26, in addition, the dispensing orifice 23 has an output dimension which is equal to the internal dimension of the downstream end 27.
    Thus, during the dispensing of the pressurized product, the tangential supply of the vortex chamber 22 makes it possible to put the product in rotation in the cylindrical part of said chamber, the product is then pressed and pushed in rotation through the upstream end 26 along the lateral surface 25 of said conical portion by forming a product sheet whose speed of rotation increases and which converges towards the downstream end 27, then said convergent sheet can impact on itself by escaping by the dispensing orifice 23 to form the aerosol.
    According to the invention, the lateral surface has at least one stepped portion 33 provided with a plurality of levels 36, which are orthogonal to the distribution axis D of the chamber 22. Thus, the stepped portions 33 have a shape of staircase whose levels 36 form the steps. The stepped portions 33 extend here from the upstream end 26 to the downstream end 27 of the conical portion, and have a width that decreases in proportion to the diameter of the conical portion between the upstream and downstream ends. In the embodiment of Figures 3 to 5, the conical portion 31 of the chamber 22 comprises four stepped portions 33 disposed periodically and symmetrically on the conical side surface 25, two stepped portions 33 facing each other. The stepped portions 33 are separated by continuous portions 37 of the lateral surface 25. Preferably, the continuous portions 37 overlie the levels 36 of the stepped portions 33 to form raised edges on either side of each stepped portion 33. Thus, , the product webs impact the flanges by rotating in the chamber along the conical surface 25. With these flanges, the turbulence in the moving product is further increased to obtain finer product droplets of uniform size. In addition, the stepped portions 33 have a width that decreases proportionally to the diameter of the conical portion 31 between the upstream end 26 and the downstream end 27.
    Furthermore, to feed tangentially the swirl chamber 22 by rotating the product along its side surfaces 25, 34 each feed channel 24 has a U-shaped section which is delimited between an outer wall 28 and an inner wall 29. outer wall 28 and inner wall 29 are orthogonal to the upstream end 26. In addition, the outer wall 28 is tangent to the cylindrical side surface 34 and the inner wall 29 is offset from it, for example by a distance of less than 30 % of the internal dimension of the upstream end 26, so as to avoid impaction of the product in said upstream end. In the embodiment shown, the inner wall 29 advantageously has an angle of convergence with the outer wall 28 in the upstream-downstream direction, the offset between said walls being then measured at the outlet section of the channels 24 in the Upstream end 26. Preferably, the inner wall 29 has a convergence angle less than or equal to 10 °. The inner wall is further connected to the cylindrical surface 34 of the chamber by a rounded corner 38, which preferably has a radius less than 0.1 mm.
    Furthermore, the downstream end of the supply channel 24 or the set of downstream ends of each of the supply channels 24 forms a supply section of the vortex chamber 22. To increase the duration of distribution of a dose of product over the operating stroke of the push button, it can be provided that this supply section is small relative to the inner surface of the upstream end 26. In particular, the surface of the feed section can be less than 10% of the inner surface of the upstream end 26. Preferably, the surface of the feed section may be between 0.01 mm 2 and 0.03 mm 2. In an exemplary embodiment, the internal dimension of the upstream end 26 is 0.5 mm, an inner surface of 0.2 mm 2, and each channel 24 has a width of 0.12 mm and a depth of 0, 13 mm, ie an area of 0.016 mm2 for the feed section.
    In the embodiment shown, the downstream end 27 of the vortex chamber is surmounted by a dispensing orifice 23 having a cylindrical geometry of revolution about the distribution axis D, the internal dimension of said orifice being equal to the internal dimension of the downstream end 27. Advantageously, the axial dimension of the dispensing orifice 23 is small relative to its internal dimension, so as not to disturb the convergence of the swirling sheet. In particular, the axial dimension of the dispensing orifice 23 may be less than 50% of its internal dimension. As a variant not shown, the downstream end 27 of the swirl chamber 22 may form a distribution orifice 23. The embodiment of the aerosol is particularly satisfactory when the internal dimension of the downstream end 27 is small relative to the internal dimension of the Upstream end 26, so that the impaction of the web is made closer to the dispensing orifice 23. In particular, the internal dimension of the downstream end 27 may be less than 50% of the internal dimension of the upstream end 26, more precisely being between 20% and 40% of said internal dimension.
    Preferably, the axial dimension of the vortex chamber 22 is relatively large, in particular of the order or greater than the internal dimension of the upstream end 26, so as to allow the establishment of the swirling sheet along the lateral surfaces. 25, 34 of said vortex chamber 22 and to confer a progressive convergence. In particular, the axial dimension of the swirl chamber 22 is at least 80% of the internal dimension of the upstream end 26, more precisely being between 90% and 200% of said internal dimension.
    According to a particular embodiment, the internal dimension of the cylindrical portion is 0.6 mm, the upstream end 26 being 0.5 mm, and the internal dimension of the downstream end 27 is less than or equal to 0.14 mm. The axial axis of the vortex chamber 22 is at least 0.45 mm, knowing that the axial dimension of the conical portion is 0.32 mm and the cylindrical portion 0.13 mm. The axial dimension of the dispensing orifice 23 is less than 0.10 mm, and the internal dimension is 0.14 mm.
    In Fig. 6, the second embodiment of the invention is a nozzle 42 similar to the nozzle of the first embodiment, except that the conical portion 41 of the chamber 42 is only partially staggered. In this case, the conical lateral surface 45 comprises stepped portions 43 which extend over a reduced portion of the lateral surface along the distribution axis. Preferably, the stepped portions 43 are arranged towards the downstream portion 46. Here, the stepped portions 43 have dimensions that go substantially from the middle of the conical portion 41 of the chamber 42 to its downstream end 47. Between the end upstream 46 and the middle of the conical portion 41, the lateral surface 45 is continuous. The other characteristics of this nozzle are the same as those of the nozzle of the first embodiment.
    The chamber 42 comprises in particular a cylindrical portion 40 at the upstream end 46 of the conical portion 41, and into which at least one supply channel 44 opens.
    According to different variants of the second embodiment, the stepped portion or portions may have variable dimensions, and arranged for example on the third, quarter, two thirds or three-fourths of the lateral surface along the axis of distribution.
    These embodiments therefore allow the use of a vortex chamber for a viscous product. The impaction of the swirling layer on the stepped portions makes it possible, in particular, to produce an aerosol formed of a uniform spatial distribution of droplets suspended in the air, the size of said droplets being small and uniform. In particular, the aerosol can then have the appearance of a smoke plume with droplet sizes of between 10 μm and 60 μm with an average of 35 μm, regardless of the support force that the user exerts on the push button, especially in the case of a needle pump.
