Definitions
- the present invention relates to a fluid dispensing head intended to be associated with a dispensing member such as a pump or a valve.
- the dispensing head may be integrated with, or mounted on, the dispenser member.
- the dispensing head may comprise a bearing surface so as to constitute a pusher on which the user presses to actuate the dispensing member.
- the dispensing head may be devoid of bearing surface. This kind of fluid dispensing head is frequently used in the fields of perfumery, cosmetics or pharmacy.
- a conventional dispensing head for example of the push-type, comprises:
- a support surface on which a user can press with a finger for example the index
- a dispensing member such as a pump or a valve
- an axial mounting housing in which a pin extends, defining a side wall and a front wall, and
- a bucket-shaped nozzle comprising a substantially cylindrical wall, one end of which is closed by a spray wall forming a spray orifice, the nozzle being mounted along an axis X in the axial mounting housing with its cylindrical wall engaged around the spindle and its spray wall in axial abutment against the front wall of the spindle.
- the inlet well is connected to the axial mounting housing by a single supply conduit.
- a swirl system at the nozzle spray wall.
- a swirl system conventionally includes a plurality of tangential swirl channels that open into a swirl chamber centered on the spray orifice of the nozzle. The swirl system is disposed upstream of the spray orifice.
- a nozzle comprising a spray wall pierced with several spray holes of substantially identical or perfectly identical diameter, of the order of 1 to 100 miti, with a tolerance of 20% .
- Such a spray wall would generate a spray whose droplet size is relatively homogeneous.
- the holes are arranged in concentric circles, with an inclination of the order of 10 to 60 degrees and a tangential orientation, so as to create a swirling spray around the central axis. The opening angle of the spray is therefore zero, or very low.
- the spray wall is curved, but the holes were drilled perpendicularly to the plane of the wall with a constant section, while the wall was still flat.
- the curvature of the wall makes it possible to make the holes diverge, once the curved wall. It is not explained in this document how or when the pierced flat wall is curved. In the drawings, the curvature of the bending is small, so that the opening angle of the spray is low.
- the present invention aims to define a flat spray wall providing a spray opening angle much larger than that of the walls of documents EP1878507A2 and EP1698399A1.
- the present invention provides a fluid dispensing head comprising a spray wall pierced with holes through which the pressurized fluid product passes to be sprayed into fine droplets, the spray wall being flat, of to define a main plane Pp, a central axis Y orthogonal to the main plane Pp, normal N parallel to the central axis Y and perpendicular to the main plane Pp, an orthogonal plane Po passing through the central axis Y and the normal N of the hole considered and a radial axis X, corresponding to the secant of the main plane Pp and of the orthogonal plane Po, characterized in that most of the holes extend along an axis Zn at an angle ⁇ of 5 to 45 degrees, advantageously 5 to 30 degrees, relative to the normal N corresponding, this axis Zn having a divergent orientation relative to the central axis Y, with a normal projection on the orthogonal plane Po having a non-zero radial component along the radial axis
- radial component it is therefore to be understood that the normal projection of the Zn axis on the orthogonal plane Po of the hole in question has a component along the X axis, which passes through the central axis Y and the normal N in the main plane Pp. In the case of tangent holes in EP1878507A2, this radial component is zero.
- the holes may all have the same orientation, with a single angle, or on the contrary, the holes may have several different orientations, with for example two or three different values for the angle a.
- the holes may have different diameters, advantageously two or three.
- the larger diameter holes may have an angle smaller than the smaller diameter holes, or conversely, the larger diameter holes may have an angle greater than the smaller diameter holes.
- the holes may be arranged in concentric circles, or alternatively, the holes may be aligned along straight line segments, the holes of the same line segment having the same angle ⁇ and the same diameter.
- Each line segment can comprise from 2 to 20 holes.
- the right segments can be arranged in parallel.
- Straight segments with holes of different diameters can be arranged in parallel.
- the line segments with holes of different diameters are arranged alternately.
- the holes may have an overall polygonal disposition, for example triangular, square, rectangular, pentagonal, hexagonal, octagonal or decagonal.
- the right sides of the polygon are formed by straight segments of holes of the same angle a and the same diameter.
- the dispensing head comprises:
- a dispensing member such as a pump or a valve
- a nozzle comprising a mounting wall engaged in the axial mounting housing, the spray wall being secured to the nozzle.
- the head can be in the form of a conventional pusher with an upper bearing surface, on which a user can press with a finger, for example the index finger.
- the axial housing then opens laterally.
- the holes may be 10 to 500 and have a diameter of the order of 1 to 100 miti, preferably of the order of 5 to 30 miti, and preferably of the order of 5 to 20 pm. The more holes there are, the smaller the diameter, and vice versa.
- the cumulative section of all the holes is preferably less than 100,000 pm 2 .
- the spirit of the invention lies in the fact of producing, in a plane spray wall, diverging holes to generate sprays whose opening angle is large, and approximately comparable to that of a conventional head with a single hole and a swirl system upstream.

- the dispensing head T is mounted on a dispensing member P, such as a pump or a valve, which has a design quite conventional in the fields of perfumery or pharmacy.
- This dispensing member P is actuated by the user by pressing axially with a finger, generally the index, on the head T.
- the normal pressure generated by this axial support on the fluid product inside the pump P and the head T is of the order of 5 to 6 bar, and preferably of 5.5 at 6 bars. Peaks at 7 to 8 bar are possible, but it is then in abnormal conditions of use. Conversely, at the approach of 2.5 bar, the spray is deteriorated, between 2.5 and 2.2 bar, the spray is strongly altered, and below 2 bar, there is no more spray.
- the initial pressure generated by the propellant gas is of the order of 12 to 13 bar and then drops, as the aerosol empties, until about 6 bars.
- An initial pressure of 10 bars is common in the field of perfumery and cosmetics.
- the pressure of the fluid product at the nozzle is of the order of 1 bar, that is to say the atmospheric pressure, or slightly less . Because of the pressure value used and the energy used, these ultrasonic vibration sprayers are outside the scope of the invention.
- the dispensing head T comprises two essential components, namely a head body 1 and a nozzle 2. These two parts can be made by plastic injection molding.
- the head body 1 is preferably made in one piece: it can however be made from several parts assembled to each other.
- the nozzle 2 can be made monobloc mono-material, but preferably, it is made by overmolding, as will be seen below.
- the head body 1 comprises a substantially cylindrical peripheral skirt 10 which is closed at its upper end by a plate 14.
- the head body 1 also comprises a connecting sleeve 15 which here concentrically extends inside the body.
- the connecting sleeve 15 extends downwards from the plate 14. It internally defines an inlet well 11 which is open downwards and closed at its upper end by the plate 14.
- connection 15 is intended to be mounted on the free end of an actuating rod P5 of the dispensing member P.
- This actuating rod P5 is movable back and forth along a longitudinal axis.
- the actuating rod P5 is hollow so as to define a discharge pipe in communication with a dosing chamber PO of the pump P or the valve.
- the inlet well 11 extends in the extension of the actuating rod P5 so that the fluid product from the dosing chamber PO can flow into the inlet well 11.
- the head body 1 defines also a feed duct 13 which connects the inlet well 11 to a mounting housing 12, as can be seen in Figure 2.
- the axial mounting housing 12 is of cylindrical overall configuration, thereby defining an inner wall which is substantially cylindrical.
- the supply duct 13 opens into the mounting housing 12 centrally. It may also be noted that the inner wall of the mounting housing 12 has attachment profiles 121 for better support of the nozzle 2, as will be seen below.
- the head body 1 can be engaged in a covering cap 3 comprising upper bearing surface 31 for a finger and a lateral envelope 32 forming a lateral opening 33 for the passage of the nozzle 2.
- the nozzle 2 has a substantially cylindrical overall configuration in the form of a small sleeve 20 which is open at both ends, but which is sealed internally by a spray wall 26 at which several holes or spray orifices O are formed. More specifically, the sleeve 20 is substantially cylindrical overall shape, preferably with axial symmetry of revolution about a Y axis, as shown in Figure 2. Thus, the nozzle 2 does not need to be oriented angularly before its presentation in front of the inlet of the axial mounting housing 12. However, it is sometimes necessary to orient the nozzle 2, because its spray wall 26 is not revolution.
- the sleeve 20 forms an external mounting wall 21 which is advantageously provided with hooking reliefs adapted to cooperate with the attachment profiles 121 of the mounting housing 12. It may be noted that the spray wall 26 extends to level of the outer wall assembly 21, where they form a plurality of projecting lugs 27 which bite into the mounting housing 12.
- a nozzle can be made.
- the first step is to drill holes O, which will be defined below. This piercing step can be performed with a LASER technique.
- a second step is to punch cutouts C around the holes O, so as to leave several bridges 27a.
- an optional step B consists of deforming the band B at the holes O for the bomber.
- the next step is to overmold the sleeve 20 on the beach surrounding the holes O and bridges 27a.
- the final step is to cut the bridges 27a around the sleeve 20 so as to leave the projecting lugs 27, which will serve to increase the resistance of the nozzle 2 in the mounting housing 12.
- the manufacturing method just described is advantageous, but not unique.
- the spray wall 26 may be attached to the sleeve 20 by any other means, such as bi-injection, snapping, crimping, swaging, etc.
- the spray wall 26 may be a one-piece mono-material part, an assembly of several parts or a multilayer product, for example laminated. It can be made of metal, plastic, ceramic, glass or a combination of these. More generally, any material that can be pierced with small holes or holes is usable.
- the thickness of the spray wall 26 at the level where the holes O are formed is of the order of 10 to 100 ⁇ m and preferably of the order of 50 ⁇ m.
- the number of holes O is of the order of 20 to 500.
- the diameter of the spray wall 26 at the level where the holes O are formed is of the order of 0.5 to 5 mm. In practice, the spray wall 26 is preferably entirely flat on both sides, so that its thickness is then constant.
- the wall 26 is not curved towards the outside.
- the density of the holes O on the wall 26 may be homogeneous, or on the contrary inhomogeneous, for example increasing or decreasing starting from the center of the wall.
- the holes O may form a network of holes comprising two series of holes O of different sizes, with the holes O of the same series having an identical or unique hole size, given manufacturing tolerances, which do not exceed 10. %. So, for a wall of In the case of a 26-hole, 100-hole punch O, there can be a first set of 50 holes O having a diameter of 10 ⁇ m and a second series of 50 holes O having a diameter of 20 ⁇ m.
- the first series of 50 holes O will generate a spray of fine droplets whose granulometric curve has a peak formed by a relatively narrow Gaussian, then the second series of 50 holes O will generate a spray of larger droplets whose particle size curve also presents a peak formed by a relatively narrow Gaussian, which is however shifted and distinct from the first Gaussian of the first series. This gives a spray with two sizes of majority droplets corresponding to the two Gaussian grain size curves.
- the distribution between the series can vary from 10 to 90%, and vice versa, with a minimum of five O holes per series.
- the hole size of the first series can vary from 15 to 50 ⁇ m, while the hole size of the second series can vary from 5 to 20 ⁇ m, with always the size of the first series much higher, at least of order of 30%, to that of the second series.
- most of the holes O are outwardly divergent with respect to the central axis Y. Some holes may, however, be parallel to the central axis Y, and in particular the holes which are located closest to this axis. Y axis. In general, the holes farthest from the Y axis are more divergent than the holes near the Y axis. It can be said that the divergence amplifies with the distance from the Y axis. However, it is not an absolute rule.
- FIGS. 4a, 4b and 4c there is shown a first embodiment, in which all the holes O are situated on one side of the central axis Y, in this case below the axis Y.
- the holes O are arranged in an aligned manner along three line segments L1, L2 and L3, which are parallel to each other, and advantageously equidistant.

- the segment L3 also comprises five holes O.
- All the holes O may have the same diameter or different diameters.
- all the holes O of the same line segment have the same diameter. In this mode of realization, there will be at most three different diameters, since there is three straight segment.
- FIG. 4 is a sectional view along a plane which passes through the Y axis and which is perpendicular to the line segments L1, L2 and
- the holes O extend along axes Z1, Z2 and Z3 which respectively make angles a1, a2 and a3 with respect to the axis Y. These angles are different from each other. others: the angle a1 of the segment L1 is smaller than the angle a2 of the segment L2 and the angle a3 of the segment L3 is the largest. Thus, the further the segment Ln moves away from the Y axis, the larger the angle an is. The angle can vary from 0 to 45 degrees.
- all the holes of the same line segment have the same orientation.
- all the holes of the same line segment are parallel to each other. It can thus be said that all the holes of the same line segment are at the same angle a year with respect to the normal to the plane of the wall at the hole considered.
- FIG. 5 is intended to illustrate the geometrical parameters making it possible to define geometrical characteristics of the orientations of the holes O.
- the spray wall 26 defines a main plane Pp.
- the spray wall 26 also defines a central axis Y.
- a normal N which is perpendicular to the plane Pp and parallel to the Y axis. It is thus possible to define orthogonal planes Po passing through the Y axis. and a normal N and an X axis passing through the Y axis and the normal N in the main plane Pp.

- the three holes O of FIG. 4c which are aligned below the Y axis in FIG. 4b, extend along axes Zn which are inscribed in their common orthogonal plane Po.
- the radial component x is then directly visible on the common orthogonal plane Po.
- the other holes O extend along Zn axes which are not inscribed in their respective orthogonal plane Po. It is then necessary to project these axes Zn normally or orthogonally to the respective orthogonal plane Po in order to be able to determine the radial component x along the axis X. It can thus be said generally that the radial component x is measured after projection of the axis Zn on the respective orthogonal plane Po, that the axis Zn is inscribed or not in this respective orthogonal plane Po.
