- Each line segment can comprise from 2 to 20 holes.
- the right segments can be arranged in parallel.

- 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.

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.

- 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.

- the angle an goes from 0 degrees, in the case where the axis Zn is parallel or coincides with the central axis Y, up to 45 degrees. An angle of about 30 degrees gives a satisfactory result. A non-zero minimum angle for year is about 5 degrees.
- the total number of holes, the arrangement of the holes on the spray wall, the number of holes per line segment or circle, the orientation of the holes and the diameter of the holes are all parameters that influence the characteristics of the spray. These parameters must be set depending on the fluid to be sprayed and the desired multiple functions: concentrated spray with a restricted opening angle or wide spray with a large opening angle, hollow or full diffusion cone, single or multiple spray Gaussian (s) of distribution, etc.
