- Figure 22 is an exploded view of the applicator assembly of Figure 21.
- the invention relates to an applicator tip 1 extending along a direction of longitudinal extension, called the main direction X, from a proximal end 1a to a distal end 1b.
- the 1 applicator tip includes:
- an external envelope 3 having an external surface 3e and an internal surface 3i, the external surface 3e defining at least an application part, the internal surface 3i defining a cavity 5,
- the internal surface 3i of the outer casing 3 is at a distance do, dl from the central element 7 in a direction orthogonal to the direction of longitudinal extension and in the longitudinal direction so as to define a free space enveloping the central element
- the term “application part” is understood to mean a part of the applicator tip 1 which is capable of retaining cosmetic product when it is brought into contact with, and of subsequently restoring it.
- the applicator tip 1 comprises a sleeve 9.
- the sleeve 9 is intended to be assembled to a rod 11, here embedded in the rod 1 1, to form an applicator.
- the sleeve 9 extends from the proximal end 1a of the application part 20 along said main direction X in the opposite direction to that which points towards the distal end 1b of the applicator tip 1 .
- the central element 7 is disposed entirely inside the cavity 5.
- the central element 7 is circumscribed inside the cavity 5.
- the central element 7 can be in material connection with the outer casing 3.
- the central element 7 is bonded in material at the distal end 1b or at the proximal end 1a.
- the central element 7 can also be in material connection with the rest of the outer casing 3, for example by bridges of material, so that this connection does not prevent movement of the outer casing 3 in direction of the central element 7 or opposite to the central element 7.
- the central element 7 can be without any connection with the outer casing 3.
- the outer casing 3 is designed so as to hold the central element 7 inside the cavity 5.
- the outer casing 3 is formed of a small thickness of material, preferably between 0.3 and 1.5 mm.
- the outer surface 3e and the inner surface 3i of the outer shell 3 are spaced 0.3 to 1.5 mm apart.
- This small thickness provides flexibility and suppleness to the outer casing 3 which can be easily moved, crushed thanks to the free space enveloping the central element 7 as will be described below.
- the movement of the outer casing 3 can be observed in particular when a pressure P is exerted on it, for example during the passage of the nozzle. applicator 1 in an opening (neck 29, wringer 31) of a container 33 or even during its application to a surface to be made up.
- the outer casing 3 comprises at least one orifice 19, 25, 27 so as to allow entry and / or exit of the cosmetic product through the latter.
- These cosmetic product entry and / or exit are advantageously favored by the movement of the outer casing 3 as explained below.
- the outer casing 3 is compressed towards the central element 7 causing pressure P on the cosmetic product contained in the cavity 5, causing it to exit. This pressure P also makes it possible to improve the distribution of the cosmetic product in the cavity 5.
- the orifices 19, 25, 27 are dimensioned so that the central element 7 cannot come out of the cavity 5.
- the cavity 5 thus serves as a reservoir of cometic product which is returned to the applicator part via at least one orifice 19, 25, 27.
- the outer casing 3 has an oblong shape, elongated in the main direction X.
- the outer casing 3 has a cross section of variable diameter, the maximum diameter d3 of which is located near the proximal end. 1 a. This shape at the proximal end 1a provides a large application surface.
- the outer casing 3 has a distal end 1b that is refined, in particular conical.

- the central element 7 can have a generally variable shape.
- the central element 7 may have a shape similar to the shape of the outer casing 3, such as an oblong shape or else be of spherical shape.
- the application part can include several different application areas 13, 15.
- the application part comprises a first application zone 13 extending in the main direction X from the proximal end 1 a of the applicator tip 1 towards an intermediate position 1 c and a second application zone 15 extending in the main direction X from the intermediate position 1 c towards the distal end 1 b of the applicator tip 1.
- Each of the application areas 13, 15 may or may not include orifices 19, 25, 27, in particular orifices 19, 25, 27 of different dimensions. This makes it possible to have an applicator tip 1 with application zones 13, 15 of different nature and thus being able to offer a variety of makeup effects.
- Figures 1 to 4 illustrate a first embodiment of an applicator tip 1 for a cosmetic product according to the invention.
- the applicator tip 1, in particular the outer casing 3 has the general shape of a flame, a section of which transverse to the main direction X is inscribed in a circle of variable diameter along the main direction. X and whose maximum diameter is d3.
- the first application area 13 is generally spherical in shape (denoted S in the figure).
- the radius of curvature is preferably between 2 and 8 mm.
- the second application zone 15 is of generally conical shape (denoted C in FIG. 1), in particular conical, the apex of which is rounded.
- the applicator tip 1 has a lower portion near the sleeve 9 which is convex towards the outside and an opposite upper portion of slightly concave shape towards the outside, the junction between the two portions being made at the level of the maximum diameter d3.
- This shape is also particularly suited to the shape of the lips and the applicator tip 1 thus has a large application surface.
- this shape allows simultaneous application to the upper lip and to the lower lip.
- the pointed distal end 1b allows more careful and precise application of the cosmetic product to a less accessible surface, for example the corner of the lips or the contour of the lips.
- the spherical part provides a large application surface.
- the outer casing 3, the cavity 5 and the central element 7 are of similar shape. They each have a maximum diameter d3, d5, d7 at the level of the maximum diameter d3 of the outer casing 3.
- the central element 7 is in direct connection with the outer casing 3 at the level of the proximal end 1 a of the applicator tip 1 by a connecting part 17.
- the central element 7 is in the extension of the sleeve 9 and extends in the direction of the distal end 1b of the applicator tip 1.
- This connecting part 17 provides rigidity to the central element 7 which is thus fixed relative to the sleeve 9.
- the first application zone 13 comprises a plurality of longitudinal slits 19 extending from the proximal end 1a of the applicator tip 1 towards the intermediate position 1c parallel to the main direction X.
- the slits 19 are oblong in shape and have a maximum transverse width at the level of the maximum diameter d3 of the outer casing 3.
- the slits 19 are separated by bands 21 of material which extend from the proximal end 1a of the applicator tip 1 towards the intermediate position 1 c parallel to the main direction X. These bands 21 are of constant width and form the outer
- This first embodiment comprises six longitudinal slots 19 spaced apart by six strips 21 of material.
- the second application zone 15 has no orifice.
- the slits 19 allow the cosmetic product to be returned to the level of the first application zone 13.
- the slits 19 extend to the second application zone 15 and are sufficiently elongated to allow distribution of the product. cosmetic in the second application area 15.
- FIGS 5 and 6 illustrate a second embodiment of an applicator tip 1 for a cosmetic product according to the invention.
- This second embodiment differs from the first embodiment by the shape of the central element 7.
- the central element 7 is a sphere in connection with the outer casing 3 at the level of the proximal end 1a of the nozzle. .
- the central element 7 is thus located in the cavity 5 defined at the level of the first application zone 13, leaving a large free space at the level of the second application zone 15.
- the central element 7 has a diameter designed so that there is a free space between the central element 7 and the inner surface 3i of the outer casing 3.
- the radius of curvature of the central element 7 is between 1 and 6 mm.
- FIGS 7 and 8 illustrate a third embodiment of an applicator tip 1 for a cosmetic product according to the invention.
- This third embodiment differs from the first embodiment by the orientation of the longitudinal slots 19 at the level of the first application zone 13.
- the slots 19 here have a helical winding around the main direction X.
- the helical winding allows to have orifices around the entire periphery of the applicator tip 1 and thus a return of the product stored in the cavity 5 over the entire application surface.
- the bands 21 of material between the slits 19 also have a width less than the width of the bands 21 of material of the first and second embodiments.
- the outer casing 3 is thus more flexible and has greater flexibility when a pressure P is exerted, favoring the exit of the cosmetic product through the slits 19.
- Figures 9 and 10 illustrate a fourth embodiment of an applicator tip 1 for a cosmetic product according to the invention. This fourth embodiment differs from the third embodiment in the shape of the central element 7.
- the central element 7 is here a sphere in connection with the outer casing 3 at the level of the proximal end 1a of the tip.
- the central element 7 is thus located in the cavity 5 defined at the level of the first application zone 13.
- the connection with the outer casing 3 is effected by means of a narrow connection part 17, in particular narrower. than in the second embodiment illustrated in Figures 5 and 6.
- the cavity 5 thus has a larger volume, which increases the cosmetic product storage capacity of the applicator tip 1.
- the reduction in the cross section of the connecting part 17 makes it possible to provide flexibility to the central element 7 and thus flexibility to the applicator tip.
- Figures 1 1 and 12 illustrate a fifth embodiment of the applicator tip 1 for cosmetic product according to the invention.
- This fifth embodiment differs from the fourth embodiment by the connection of the central element 7 with the outer casing 3.
- the central element 7 is a sphere but the latter is in connection with the outer casing 3 at the level of the distal end 1b.
- the central element 7 is in the extension of the distal end 1b and extends into the cavity 5 in the direction of the sleeve 9.
- the end piece does not have any cavity 5 at the level of the second application zone 15, in other words, the interior of this second application zone 15 is full.
- the cavity 5 is only located at the level of the first application zone 13.
- the slits 19 are wound helically around the main direction X. They extend from the proximal end 1a to the second application zone 15. Thus, so advantageously, the slits 19 open into the cavity 5 located at the level of the first application zone 13 and form channels 23 at the level of the second application zone 15. Thus the cosmetic product which leaves the slits 19 can be directed in the direction of the second application zone 15 via these slits 19. Cosmetic product is thus available at the level of the two application zones 13, 15.
- Figures 13 to 16 illustrate a sixth embodiment of an applicator tip 1 for a cosmetic product according to the invention. This sixth embodiment differs from the first embodiment by the presence of a plurality of orifices at the level of the second application zone 15.
- the orifices of the second application zone 15 are circular orifices 25 with a diameter preferably between 0.5 and 3 mm.
- the circular orifices 25 are arranged in two radial rows. Each of the rows comprises six circular orifices 25. For better restitution over the entire surface of the second application zone 15, the circular orifices 25 of a radial row have an angular offset with respect to the circular orifices 25 of the other radial row.
- the slits 19 are also shorter than in the first embodiment and extend over only the first application zone 13.
- cosmetic product can be restored at the level of the two application zones 13, 15.
- the circular orifices 25 of the second application zone 15 are thus of smaller dimension than the orifices (slots 19) of the first application zone 13.
- the quantity of product returned is varied. It is thus possible to restore a small quantity of product by applying a pressure P at the level of the second application zone 15 and a larger quantity by applying a pressure P at the level of the first application zone 13.
- Figures 17 and 18 illustrate a seventh embodiment of an applicator tip 1 for a cosmetic product according to the invention. This seventh embodiment differs from the sixth embodiment in the orientation of the longitudinal slots 19 at the first application zone 13.
- the slots 19 have a helical winding around the main direction X.
- FIGS. 19 and 20 illustrate an eighth embodiment of an applicator tip 1 for a cosmetic product according to the invention.
- This eighth embodiment differs from the seventh embodiment by the shape of the orifices of the second application zone 15 which are in the form of secondary slots 27, here six in number, which are of smaller dimension than that of the slots 19. of the first application zone 13 so as to be able to regulate the quantity of cosmetic product returned.
- the secondary slits 27 extend longitudinally over almost the entire length of the second application zone 15 and have an inclination with respect to the main direction X. The elongated shape of these secondary slits 27 allows restitution of cosmetic product over the entire length. surface of the second application area 15.
- the first mechanism of use is illustrated in Figures 1 to 4, taking as an example the applicator tip 1 of the first embodiment. This mechanism is however applicable to any applicator tip 1 according to the invention.
- Figures 1 and 2 illustrate the applicator tip 1 in a position in which no pressure is exerted on the outer surface 3e of the outer casing 3.
- a free space is defined all around the central element 7 and surrounds the latter, except at the level of the connecting part 17 between the outer casing 3 and the central element 7.
- the outer casing 3 approaches the central element 7 which remains fixed to it with respect to the sleeve 9 as can be seen in FIG. 3.
- the zone of the outer casing 3 is opposite. at the pressure point moves away from the central element 7. This movement causes the exit of the cosmetic product stored in the cavity 5 through the orifices (here slots 19) located at the level of the first application zone 13.
- the slits 19 are sufficiently elongated in the direction of the distal end 1b of the end piece so that the second application zone 15 is also supplied with cosmetic product.
- a more sustained pressure P causes the movement of the outer casing 3 until the inner surface 3i of the latter is in contact with the central element 7 as can be seen in FIG. 4.
- the pressure P applied to the applicator tip 1 is applied radially.
- the second mechanism of use is illustrated in Figures 13 to 16 taking as an example the applicator tip 1 of the sixth embodiment. This mechanism is however applicable to any applicator tip 1 according to the invention.
- FIG. 13 and 14 illustrate the applicator tip 1 in a position in which no pressure is exerted on the outer surface 3e of the outer casing 3.
- a free space is defined all around the central element 7 and surrounds it, except at the level of the connecting part 17 between the outer shell 3 and the central element 7.
- a pressure P exerted at the distal end 1b of the applicator tip 1 causes displacement of the outer casing 3. This movement is enabled by the flexibility of the outer shell 3.
- the free space between the inner surface 3i of the outer casing 3 and the central element 7 is reduced when the pressure P is applied.
- the distance dl, do between the inner surface 3i of the outer casing 3 and the central element 7 decreases over the entire periphery of the nozzle, in particular at the level of the second application area 15.
- This pressure P is particularly advantageous for making the cosmetic product exit through the orifices 25, 27 at the level of the second application zone 15.
- the two mechanisms of use can be combined.
- the applicator tip 1 is a single monolithic piece obtained without assembly.
- the applicator tip 1 is not obtained by assembly.
- Assembly is understood here as putting together, bringing together at least two isolated elements, but does not exclude the possibility of several steps.
- the applicator tip 1 described above is obtained by an additive manufacturing process.
- additive manufacturing process means a manufacturing process by adding material, generally aided by computer. Such a manufacturing process is also called three-dimensional printing or even 3D printing.
- the use of three-dimensional printing can make it possible to produce in a single step an applicator tip 1 in a single piece and in continuity of material comprising an outer casing 3 and a central element 7.
- an applicator tip 1 could prove to be very complex or even impossible to obtain, in particular in a single piece, by a conventional injection molding process. It is thus possible to produce, directly and by a single manufacturing operation, the applicator tip 1.
- this technique makes it possible to dispense with the use of complex molds.
- the three-dimensional printing is used to form the applicator tip 1 with the sleeve 9 and / or the rod 11.
- Different additive manufacturing technologies known to those skilled in the art can be used. In particular, it can be:
- LOM Laminated Object Manufacturing
- these are sintering and / or stereolithography technologies.
- the invention also relates to a method of manufacturing an applicator tip 1 as described above.
- the process includes:
- the digital model is a computer file which corresponds to a virtual model of the applicator tip 1.
- the applicator tip 1 is first of all modeled so as to obtain a CAD model which is then converted into a format. appropriate such as an .STL file.
- the file is then used on an additive manufacturing machine.
- the digital model is cut into a number of layers depending on the desired precision.
- the layers correspond to a cross section of the tip.
- Suitable materials for making the applicator tip 1 by three-dimensional printing are polyamides, photosensitive resins, polylactic acid (PLA), acrylonitrile butadiene styrene (ABS), polypropylene (PP).
- FIGS. 21 and 22 illustrate an applicator assembly for a cosmetic product, comprising a container 33 comprising a body 35 forming a reservoir intended to contain the cosmetic product, and an applicator comprising an applicator tip.
- the applicator is adapted to be fixed on the container 33, so that the applicator tip 1 is housed inside the reservoir. It is thus immersed in the cosmetic product marked 37 in FIG. 21.
- Figure 21 also illustrates the sleeve 9 assembled with the rod 11 of the applicator, called the rod 11 of manipulation.
- the rod 1 1 allows, among other things, manipulation of said applicator tip 1. More specifically, the applicator comprises a closure cap 39 adapted to be handled by the user and the rod 1 1 advantageously extends from the stopper 39 .
- the plug 39 is formed of a head 41 made from material with the rod 1 1, and a cover 43 force-mounted and held in position on the head 41 of the rod 1 1 to the 'Using internal counter-forms intended to cooperate with forms produced on the head 41.
- the cover 43 is rigid.
- the stopper 39 is intended to be removably attached to an opening belonging to the container 33. Said opening is here the neck 29 through which the cosmetic product can be extracted.
- the sleeve 9 and the rod 11 each have a substantially cylindrical shape and a main direction of longitudinal extension coincident with the main direction X.
- Figure 22 is an exploded view of the applicator assembly of Figure 21.
- Figure 22 illustrates the container 33 in detail.
- the container 33 comprises the wringer 31, intended to be fixed inside said neck 29.
- the wringer 31 comprises a wringing orifice 45 configured to scrape the excess cosmetic product from the rod 11 and from the applicator tip 1 when the latter pass through it.
- the wiping orifice 45 is advantageously cylindrical in shape; this choice is not limiting and any other form of orifice 45 may be chosen for the wringer 31 without departing from the scope of the invention.
- the diameter d45 of said wiping orifice will advantageously be chosen in relation to the diameter D of the rod 11 and the maximum diameter d3 of the applicator tip 1 from which it scrapes the excess product on board.
- the diameter d45 of the wiping orifice 45 can be substantially the same as the diameter d3 of the applicator tip 1. This has the advantage of slightly scraping the product off the applicator tip 1.
- the outer casing 3 being soft and flexible, it is possible that the diameter d45 of the wiping orifice 45 is slightly smaller than the diameter d3 of the applicator tip 1. This has the advantage of distributing the cosmetic product stored in cavity and eliminate any surplus stored in cavity 5.
- the applicator assembly is designed so that the wiping of the applicator tip 1 is optimized. during its extraction from the container 33. In other words, the quantity of cosmetic product that the applicator tip 1 is able to take on board is optimized by the wiper 31 through which it passes during its extraction from said container 33.
- the applicator assembly 31 can be obtained in whole or in part by three-dimensional printing.
- the embodiments may be combined without departing from the scope of the invention.
