- 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 pm, with a tolerance of 20%.
- Such a spray wall would generate a spray whose droplet size is relatively homogeneous.
- the wall is curved and the holes are then divergent. The opening angle of the spray remains low.
- the spray wall is of constant thickness, but curved.
- the holes were drilled perpendicular to the plane of the wall, 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 specified that the holes have, after bending, a constant section over their entire length. 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 spray wall whose deformation in the final state allows not only to diverge the holes, but also to influence their diameter and their section.
- the present invention provides a fluid dispenser head having a hole-drilled spray wall through which the pressurized fluid passes to be sprayed into fine droplets, the spray wall defining a central axis. X and having two faces connected by the holes, the holes having a divergent orientation relative to the central axis X, the spray wall having a variable thickness, so that the two faces are more or less distant one of the 'other.
- the thickness increases, advantageously in a regular manner, from the central axis X radially outward. In other embodiments, the thickness increases, advantageously in a regular manner, in the direction of the central axis X radially inwards. It is also possible that the variation in thickness is not constant, thus alternating areas of increasing thickness and areas of decreasing thickness. Conversely, the variation of the thickness can also be perfectly and linearly progressive. As for the magnitude of the variation of the thickness, it can increase from 50% to 400%, advantageously from 100% to 200%.
- the holes may have decreasing diameters from the central axis X radially outwards, or conversely, decreasing diameters in the direction of the central axis X radially towards the inside.
- the faces (26a, 26b; 126a, 126b) of the spray wall (26; 126) are curved with different radii of curvature.
- the 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 in the number of 10 to 500 and have a diameter of the order of 1 to 100 ⁇ m, advantageously of the order of 5 to 30 ⁇ m, and preferably of the order of 5 to 20 ⁇ m. pm. More holes, the smaller their diameter, and vice versa.
- the cumulative section of all holes is less than 100,000 pm 2 .
- the present invention also defines a method of manufacturing a spray wall as defined above, comprising the steps of:
- the strip is flat and of constant thickness
- step a- comprises drilling holes of identical diameter perpendicularly to the strip, so as to obtain, after step b-, a spray wall with diverging holes of diameters and / or different sections.
- the diameter of the holes may decrease or increase depending on the deformation stresses exerted on the pierced flat wall.
- the diameter of the holes will increase when the area of the wall increases, and vice versa.
- the section of the hole will increase from the inner face to the outer face, for example cone-shaped, when the surface of the outer face increases more than that of the inner face, and vice versa.
- the orientation, the diameter of the holes and the section of each hole can be determined according to the type of deforming stress that is exerted on the pierced flat wall. There is an infinity of possible configurations for the spray wall.
- step b- is carried out by stamping, advantageously with a convex matrix and / or a concave punch, or vice versa. With this stamping technique, it is possible to locally exercise more or less strong stresses on one or both sides of the strip, which will lead to its localized and controlled deformation.
- the present invention also defines a fluid dispenser comprising a fluid dispenser head as defined above, mounted on a pump or a valve, itself mounted on a fluid reservoir.
- the spirit of the invention resides in the controlled reduction of the thickness of the spray wall, in order to influence the orientation of the holes, the diameter of the holes and / or the section of each hole. It is advantageous to start from a plane strip of constant thickness that holes are drilled whose orientation is preferably perpendicular to the plane plane plane. Holes inclined relative to the plane plane plane are also possible. A non-planar band of non-constant thickness can even be used, although this seems difficult in practice.
- FIG. 1 is a vertical cross-sectional view through a pump equipped with a dispensing head according to the invention
- FIG. 2 is a greatly enlarged view of the dispensing head of FIG. 1,
- FIG. 3a is a very greatly enlarged view in cross section through the spray wall of FIGS. 1 and 2,
- FIG. 3b is a view similar to that of FIG. 3a of the spray wall in the initial state before forming
- FIGS. 4a and 4b are plan views of the spray wall, respectively in the initial state before forming and in the final state after forming, and Figures 5 to 8 are views similar to that of Figure 3a for four other embodiments of the invention.
- 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. peripheral skirt 10.
- the connecting sleeve 15 extends downwardly from the plate 14. It internally defines an inlet well 11 that is open downwards and closed at its upper end by the plate 14.
- the sleeve connecting piece 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 1 1 extends in the extension of the actuating rod P5 so that the fluid from the dosing chamber PO can flow into the inlet well 1 1.
- the head body 1 also defines a supply duct 13 which connects the inlet well 1 1 to a mounting housing 12, as can be seen in FIG. 2.
- the axial mounting housing 12 is of cylindrical overall configuration, thus defining a 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 01 are formed, 02, 03. More specifically, the sleeve 20 is substantially cylindrical overall shape, preferably with axial symmetry of revolution about an axis X, as shown in Figure 2. Thus, the nozzle 2 does not need it is angularly oriented 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.
- the spray wall 26 is fixed to the nozzle body 20 by any means, such as overmoulding, bi-injection, monoblock mono-material molding, 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. Preferably, this material is flowable, in that it can be deformed by generating variations in shape, size and / or thickness.
- the spray wall 26 defines an outer face 26a and an inner face 26b which are connected by the holes 01, 02, 03.
- the thickness of the spray wall 26 at the level where the holes is of the order of 10 to 100 mih.
- the thickness of the spray wall 26 is variable, so that the two outer 26a and inner 26b faces are more or less distant from each other.
- the diameter of the spray wall 26 at the level where the holes are formed is of the order of 0.5 to 5 mm.
- the spray wall 26 is bulged outwards.
- the holes may be in the number of 10 to 500 and have a diameter of the order of 1 to 100 ⁇ m, advantageously of the order of 5 to 30 ⁇ m, and preferably of the order of 5 to 20 ⁇ m. pm.
- the cumulative section of all the holes is preferably less than 100,000 pm 2 .
- FIG. 3b we see a flat strip 26i having a constant thickness e1, which can be of the order of 50 pm.
- This flat strip 26i may be metal, such as stainless steel.
- O holes have been drilled, for example by laser, with a perpendicular orientation.
- the holes O are all the same diameter and have a substantially constant cross section. Without departing from the scope of the invention, the holes O could be inclined, have different diameters and non-constant sections, for example conical.
- this perforated plane strip 26i is then deformed, advantageously by stamping between a matrix M and a punch N of suitable shapes.
- the matrix M comprises a projecting boss M2 to form the internal face 26b and the punch N comprises a recess N2 to form the external face 26a.
- the boss M2 is surrounded by a flat peripheral area M1 and the recess N2 is surrounded by a corresponding flat peripheral area N1.
- the respective curvatures of the boss M2 of the matrix M and the recess N2 of the punch N may be regular and have a radius of curvature.
- the radius of curvature of the boss M2 is smaller than that of the recess N2.
- a spray wall 26 defining a deformed zone 262 surrounded by a peripheral plane flange 261 is obtained. Due to the difference in radii of curvature between the M2 boss and the recess N2, the thickness e2 of the spray wall 26 on the X axis is less than the initial thickness e1 found on the peripheral flange 261 and on the outer edge of the deformed zone 262.
- This thickness e2 may be of the order of 5 to 40 ⁇ m, advantageously 10 to 30 ⁇ m and preferably 25 ⁇ m.
- the deformation of the plane strip 26i to create the deformed zone 262 has modified the orientation of the holes O.
- the holes O which were initially parallel to each other and to the Y axis, are now oriented inclined relative to the axis X.
- the holes have three different orientations depending on their distance from the X axis.
- the holes 01 closest to the X axis are slightly inclined because they are positioned at the top of the bending.
- the holes 02 have an intermediate inclination and the holes 03 furthest from the X axis have the strongest inclination.
- the inclinations can range from near 0 degrees to 45 degrees or more. It is easy to understand that these inclinations are dependent on the magnitude of the radii of curvature of the faces 26a and 26b.
- a deformed zone 262 with a shallow bending will lead to relatively small hole inclinations.
- the holes 01, 02 and 02 have different diameters: the holes 01 are smaller than the holes 02, which are smaller than the holes 03.
- the holes 01 have a diameter close to that of the holes O, because the deformation of the flat strip 62i at the holes 03 has been accompanied by a small reduction in thickness.
- the holes 02 are located at a location where the thickness reduction is sensitive and the holes 03 are located at a point where the reduction in thickness is maximum.
- the holes O initially drilled have a diameter of the order of 5 pm
- the holes 01 may have a diameter almost unchanged on the order of 5 pm
- the holes 02 may have a diameter of the order of 10 pm
- the holes 03 may have a diameter of the order of 15 ⁇ m.
- the holes 01, 02 and 03 are each represent a constant section, in particular cylindrical over their entire length. In practice, it is possible, if not inevitable, for the section of each hole to change from a cylindrical configuration to a conical configuration open to the outside.
- the deformation of the plane strip 26i with reduced duct wall thickness results in a spray wall 26 with a deformed zone of variable thickness, at the level of which the holes 01, 02 and 03 have different inclinations, different diameters and possibly a conical section.
- the variation in diameter and / or section comes from the local stretching of the band, with an increase in the surfaces of the faces 26a and 26b, and the change of orientation of the holes comes from the bending, and more generally from the slope made by the faces 26a and 26b relative to the X axis at the location of each hole.
- the deformation (or forming) of the deformed zone 262 with reduction of wall thickness can be very diverse: the outer and inner faces can be spherical, ellipsoidal, ovoidal, regularly smooth, or on the contrary faceted flat or frustoconical, as we will see it with the four embodiments below.
- FIG. 5 shows a spray wall 26 which seems close to that of FIG. 3a, with the difference that the radii of curvature of the external faces 126a and the internal faces 126b have been reversed, so that the deformed zone 263 has a minimum reduced thickness e3 at its outer edge, near its junction with the peripheral flange 261 and maximum thickness e1 on the X axis.
- the holes 01 1, 012 and 013 thus have increasing diameters outwardly from the X axis, or otherwise decreasing in the direction of the X axis.
- the inclinations of the holes may be identical to those of the embodiment of Figure 3a.
- the section of each hole may be constant, or conversely variable, for example tapered outwards.
- Figure 6 shows a spray wall with a deformed zone 264 having an outer face 226a convex, like those of Figures 3a and 5 and an inner face 226b formed of plane facets or frustoconical sectors 22b.
- the holes 04 may have an identical diameter, but an outwardly flared section.
- the holes 04 may be positioned at the level where the facets or frustoconical sectors 22b meet, in order to amplify the deformation of the initial holes.
- FIG. 7 shows a spray wall which is, as it were, the opposite of that of FIG. 6, with a deformed zone 265 comprising an outer face 326a with facets or frustoconical sectors 32 a and one face domed inner 326b, comparable or identical to that of Figures 3a and 5.
- the prominence of the deformed area 265 is less, compared with those of the previous embodiments, but the deduction of wall thickness is stronger.
- Holes 05 and 06 have decreasing diameters starting from the X axis and having a conical section open towards the outside.
- FIG. 8 shows a spray wall of different design, with a non-projecting or prominent deformed zone 266, comprising an outer face 426a that is perfectly or substantially flat and a concave inner face 426b in the form of a cone with its tip on the X axis.
- the material has here been pushed outward, so that the thickness e5 of the peripheral flange 261 has increased, for a minimum thickness e4 on the axis X.
- the diameter of the holes 07, 08 and 09 is increasing from of the X axis, while the initial diameter of the holes was that of the holes 09. In other words, the holes 07 and 08 result from a decrease in diameter, because the material was compressed, without being able to increase of surface.
- the holes 07, 08 and 09 are represented with a constant section, but in reality, the very strong compression of the material has an inevitable impact on the section, which can have a complex configuration, such as in trumpet, diabolo, spin or in an arc.
- creep deformation stresses can be applied to a band of flowable material pierced with holes, so as not only to modify the orientation or inclination of the holes, but to increase or decrease the diameter of the holes and / or to modify their section.
- Embossing is a known technique and easy to implement. The particular profiling of the die and the punch makes it possible to produce a wide variety of spray walls, with very varied hole orientations, increasing or decreasing diameters and original sections.
- the band of flowable material is preferably flat with a constant section, as this type of product is readily available commercially. However, the present invention could also be implemented on non-planar and / or non-constant thickness strips.
- the spray wall has a variable thickness, so that the two faces are more or less distant from each other.
- stamping with reduction of thickness is a preferred technique, because it allows during a single operation to influence the orientation, but also on the other characteristics (diameter - section - shape) holes previously drilled.
