COSMETIC APPLICATOR.
The invention relates to an applicator (1) for a cosmetic product comprising protuberances (11) each comprising a base and arranged in at least two groups (10) of protuberances, the applicator having a longitudinal axis.
The bases of the protrusions of the same group forming at least one closed loop (12) which is not crossed by the longitudinal axis (9) of the applicator.
FR 3 053 581 - A1

-1The invention relates to cosmetic product applicators.
A mascara article, or “mascara”, conventionally comprises a case, a mascara reservoir and an applicator. There are in particular two types of applicators, those of the brush type and those injected. A brush-type applicator forms a brush which includes bristles formed by fibers trapped in a twisted wire forming the core of the applicator. An injected applicator is in one piece and has plastic bristles or teeth. Such applicators give satisfactory results to the user. But the latter is always looking for new or better makeup effects, as well as better application comfort. Among the improvements, we can note the search for a better separation of the eyelashes, a better lengthening and / or curling effect of the eyelashes, or even a different make-up effect depending on the location of the eyelash in a row of eyelashes.
An object of the invention is therefore to improve the applicators of cosmetic product.
To this end, there is provided according to the invention an applicator of cosmetic product comprising protuberances each comprising a base and arranged in at least two groups of protuberances, the applicator having a longitudinal axis, the bases of the protuberances of the same group forming at least one closed loop which is not crossed by the longitudinal axis of the applicator.
Thus, the presence of protuberance groups makes it possible to locally create zones on the applicator which provide a particular makeup effect. It is in this way possible to provide different groups of protrusions arranged along the applicator and each making up the eyelashes differently along a row of eyelashes, thereby providing the user with a particular makeup effect. The fact that the bases of the protuberances of the same group of protuberances form a loop makes it possible to accentuate the makeup effect by zone. The fact that the loop is not crossed by the longitudinal axis of the applicator makes it possible to organize the protuberances even more locally in order to obtain the desired makeup effect.
The number of protrusion groups may vary. One can for example provide an applicator comprising between 2 and 50 groups of protuberances, or even between 5 and 40 groups of protuberances, preferably between 10 and 30 groups of protuberances. Of course, an even greater number of protuberance groups can be provided.
In addition, the different groups of protrusions can be formed by a different number of protrusions. It can be provided that a group of protuberances is composed of 4 to 200 protuberances, or even 15 to 100 protuberances, for example from 30 to 50 protuberances. Provision may be made for all the groups of protuberances to be composed of an identical number of protuberances.
Within the same group of protuberances, the protuberances can all be
-2 identical or different with regard to their shape, size and / or orientation.
Furthermore, as the bases of the protrusions of a group form a closed loop, it favors the constitution of a reserve of makeup product in the center of the group, in particular by capillarity. This reserve is in the immediate vicinity of the protuberances which ensure makeup by coming into contact with the eyelashes. It therefore makes it possible to deliver this product as soon as the eyelashes come into contact with the group. The eyelashes can even come directly into contact with the product in this reserve.
Advantageously, the protuberances of at least one of the protuberance groups form at least one crown, preferably the protuberances of each protuberance group forming at least one crown.
This conformation has the advantage of being ordered, compared for example to a tufted conformation, and thus allows better control of the makeup effect obtained with the applicator. The protrusions are thus well individualized within the crown and thus allow good separation of the eyelashes during the application of the mascara. It can be foreseen that the protrusions extend, from the loop formed by their bases, towards the outside of the group, that is to say in the direction opposite to the longitudinal axis of the applicator.
Preferably, a main axis of at least one of the protuberance groups extends in a plane perpendicular to the longitudinal axis of the applicator.
The main axis of a group of protrusions corresponds to the axis that passes through the center of the loop. Here again, it can be foreseen that the protuberances of the group extend from the loop towards the outside of the group and thus facilitate the application of the mascara.
Advantageously, the groups of protrusions form at least two sets, each group of protrusions having a main axis, the main axes of the groups of the same set extending in the same plane.
The sets of protuberance groups again allow regions to be created providing specific and different makeup effects along the longitudinal axis of the applicator. It can be provided that a set of protuberance groups is composed of 2 to 10 protuberance groups, or even 3 to 7 protuberance groups, preferably 4 to 6 protuberance groups. Provision may be made for the protuberance groups of the same assembly to be spaced one by one at a constant angle relative to the main longitudinal axis of the applicator. It can also be provided that the groups of protuberances of the same assembly are spaced one by one at a different angle relative to the longitudinal axis.
In addition, it can be foreseen that the plan comprising the main axes of the groups
-3 protrusions of the same assembly has any orientation with respect to the longitudinal axis of the applicator. Preferably, this plane is perpendicular to the longitudinal axis. The planes of the different sets of protrusions can form different or identical angles with each other with the axis. It can be expected that this angle is between 0 ° and 90 °, or even between 20 ° and 70 °, for example between 40 ° and 60 °. The case where all the planes form the same angle with the longitudinal axis is advantageous since it limits the size of the applicator, or even provides a space saving allowing the presence of a higher number of sets of groups of protuberances.
Preferably, the plane comprising the main axes of the protuberance groups of one of the sets of groups is parallel to the plane comprising the main axes of the protuberance groups of another of the sets and distant from this plane.
As explained above, this arrangement limits the size of the applicator and saves space allowing the presence of a greater number of sets of protuberance groups on the applicator. Preferably, all the planes comprising the main axes of the protuberance groups of the same assembly are parallel to each other.
Preferably, in at least one of the assemblies, the main axes of at least two of the protuberance groups are combined.
It can be expected that a set of protuberance groups includes several groups whose main axes are combined. For example, one can provide an assembly comprising at least four groups of protrusions, these groups being distributed in two subgroups composed of two groups in which the main axes of the groups are combined.
Advantageously, in at least one of the assemblies, the main axes of at least two of the protuberance groups are perpendicular.
It can be envisaged that a group of protuberances includes several groups whose main axes are perpendicular. One can for example provide that the main axes of all the groups of the same set are perpendicular two by two.
Preferably, in at least one of the sets, at least two of the protuberance groups are the image of one another by a rotation around the longitudinal axis of the applicator, preferably all the protuberance groups of the whole being the image of one another by this rotation.
This creates a zone on the applicator for which, whatever the angle of rotation of the applicator along its longitudinal axis with respect to the eyelashes, there is the same makeup effect for a given position along the applicator. We can predict that the rotation is between 20 ° and 180 °, or even between 45 ° and 120 °, for example between 70 °
-4and 90 °.
Advantageously, at least two of the sets are symmetrical to each other with respect to a plane.
In this way, the eyelashes arranged along a row of eyelashes will be made up in the same way at two different areas of the row of eyelashes, interspersed with an area made up in another way. Thus, we obtain a makeup effect "by area" which is particularly pleasant and sought after by the user. We can predict that the plane of symmetry is perpendicular to the longitudinal axis of the applicator.
Preferably, at least one of the assemblies is the image of itself by a rotation of less than one turn around the longitudinal axis of the applicator.
In the same way as above, this characteristic makes it possible to make up in the same way, whatever the orientation of the applicator around its longitudinal axis with respect to the eyelashes, the eyelashes arranged at a given level over the length of a row of eyelashes.
Advantageously, at least two of the protuberance groups of at least two of the assemblies are aligned along the longitudinal axis of the applicator.
This makes it possible to make up all the eyelashes of a row of eyelashes or to make up by area of the eyelashes in accordance with the desired effect, that is to say that certain eyelashes of the row will be made up in a way and that other lashes in the row will be made up in some other way. Provision may also be made for a group of protuberances from a given set of groups to be aligned along the longitudinal axis of the applicator with a group of protuberances from each set of groups that the applicator comprises.
Preferably, the applicator is arranged so that it does not comprise two groups of respective protuberances of at least two of the assemblies which are aligned along the longitudinal axis of the applicator.
This arrangement has in particular the advantage of making it possible to reduce the size of the sets of protuberance groups on the applicator, thus making it possible for example to arrange the different sets closer to one another.
Advantageously, at least one of the protuberance groups is formed by at least a double row of protuberances, the respective bases of which form a closed loop.
This double row provides a better makeup result. More particularly, it makes it possible to better separate the eyelashes and to better smooth the mascara on the eyelashes, thus avoiding the formation of “bundles”. We can of course provide that the closed loop is formed by the bases of more than one double row of protrusions,
-5 For example by the bases of a triple row, or even a quadruple row or a quintuple row.
Preferably, at least one of the protuberance groups, preferably each group, has a central opening passing right through the applicator.
This central opening passing right through the applicator, or recess, makes it possible to give the protuberance groups, as well as the applicator as a whole, greater flexibility. This characteristic thus makes the application of makeup more pleasant for the user. It can be provided that this opening is covered by a trellis.
Preferably, the central openings of at least two of the protuberance groups communicate with each other, preferably the central openings of all the protuberance groups communicating with each other.
This improves the flexibility of the applicator and therefore makes the application of makeup more pleasant. In addition, it allows the mascara to flow between these groups and therefore improves the distribution of the product between the groups, thereby facilitating makeup.
Advantageously, the applicator further comprises at least one group of protuberances, a main axis of which coincides with the longitudinal axis of the applicator.
This provides a group of protrusions at the free end of the applicator. This particular position allows the user to make more precise make-up gestures which are useful in particular when the latter wishes to make make-up alterations or make up the small eyelashes situated at the ends of the eye.
Advantageously, the applicator further comprises at least one support for a group of protuberances, this support extending from a core of the applicator, preferably each group of protuberances being supported by such a support.
This feature increases the number of protuberance groups that the applicator can understand for a given applicator size. Indeed, this support makes it possible to increase the distance between the main axis of the applicator and a group of protuberances carried by this support, thus freeing up a space between this group and the central part of the applicator which can therefore include a another group of protuberances. This support may for example consist of a swelling of a core of the applicator.
Preferably, the loops formed by the bases of the protrusions of at least two distinct groups differ by at least one dimension.
This characteristic contributes to providing makeup effects which are locally different. Among the dimensions of the loop which may vary, there is in particular the largest as well as the smallest dimension of the loop.
Preferably, the loops formed by the bases of the protuberances of at least two distinct groups have identical dimensions, preferably all the loops formed by all the groups of protuberances being identical.
This characteristic is particularly interesting because it makes it possible to create repetitions, or even uniformity, of the makeup effect obtained at the level of each of the protuberance groups.
Advantageously, at least one of the loops has a generally oblong shape.
It can of course be provided that the loops have another general shape, for example circular, parallelepiped or square. The loops can have different shapes between them or be all identical.
Preferably, at least one of the loops is non-planar.
This characteristic makes it possible to give the eyelashes a particular curvature which is a makeup effect sought by the user. One can for example provide that this loop is curved, curved, or wavy.
Advantageously, at least one of the loops extends around the longitudinal axis of the applicator over a range between 20 ° and 350 °, preferably extending over a range between 180 ° and 300 °.
Preferably, at least one of the loops has a general helical shape.
This particular configuration makes it possible to increase the curvature of the eyelashes, which constitutes a makeup effect sought by the user.
Advantageously, a direction of a larger dimension of at least one of the loops is parallel to the longitudinal axis.
It can be expected that the largest dimensions of all the loops are parallel to the longitudinal axis.
Preferably, a direction of a larger dimension of at least one of the loops is inclined relative to the longitudinal axis by an angle between 5 ° and 90 °.
It can be expected that this inclination is equal for all the loops. It can also be provided that all the loops have different inclinations.
Advantageously, the applicator comprises a hollow core.
This feature creates a lighter applicator, which makes makeup easier. In addition, it gives the applicator flexibility which makes the makeup more pleasant for the user. The hollow core is formed by a wall. It can be expected that this wall has a constant thickness over its entire length. It is also possible to provide for this wall to be solid or perforated. In the latter case, one can for example provide that the wall forms a more or less tight trellis or mesh. The openwork character makes the applicator more flexible and therefore the makeup application more pleasant for the user.
Advantageously, the applicator is arranged so that, in view of the end, no space is left free by the protrusions on the whole of a periphery of a core of the applicator.
Thus, whatever the degree of rotation of the applicator about its axis, there is a region of the row of eyelashes which is made up by the applicator.
Preferably, the applicator comprises a core having more than ten orifices extending outside the loops.
As explained above, this characteristic contributes to making the applicator more flexible and therefore its use more pleasant for the user. It is conceivable that the core is formed by a mesh or trellis or has an exoskeleton structure.
A cosmetic article comprising an applicator as described above is further provided according to the invention.
According to the invention, there is also provided a method of manufacturing by additive synthesis of an applicator as described above, comprising the steps of:
- obtaining data relating to the applicator; and
- additive summary of the applicator using data.
The advantage of this method of manufacture is in particular that it allows the production of applicators having a complex structure, which would be difficult or even impossible to produce by injection, taking into account in particular the existence of certain undercut parts.
Different additive synthesis methods known to those skilled in the art can be used to manufacture the invention. Examples include selective laser sintering (or SLS for Selective Laser Sintering) and stereolithography (SLA). An example of a process for manufacturing a cosmetic product applicator by additive synthesis is described in application WO 2008/113939 in the name of the applicant.
An electronic recording medium is also provided according to the invention comprising, in recorded form, data making it possible to implement the method as described above.
In addition, according to the invention, a computer file is provided comprising data suitable for use by a computer program to control the implementation of the method as described above.
Finally, there is also provided according to the invention a method of making available on a telecommunications network a computer file comprising data capable of being used by a computer program to control the implementation of the method as described above. , for download.
We will now present several embodiments of the invention by way of nonlimiting examples with reference to the drawings in which:

We will now present four embodiments of the applicator and of the method according to the invention with reference to FIGS. 1 to 5E. We will describe here mascara applicators but it is of course possible to provide for the use of the applicator according to the invention with another cosmetic product, for example nail polish, lipstick or gloss.
The mascara applicator 1 described in this embodiment is part of a cosmetic article 2 comprising a cap or a plug 3, to which the applicator 1 is rigidly connected, and a case 4 comprising a reservoir of mascara 5 and a wringer 6 (see Figure 1) housed in the neck of the tank on which the cap can be fixed, for example screwed, removably to close the tank of the article. The applicator then extends into the reservoir and is bathed in mascara.
Of course, other types of articles with mascara applicators can be envisaged, for example articles of the “pen” type in which the applicator is not linked to a cap or articles in which the applicator does not bathe in the mascara reserve when not in use.
The applicator is carried by a straight rod 8 which connects it to the cap 3. The applicator has a generally elongated shape along its longitudinal axis 9. The rod 8 has a generally straight cylindrical shape. The rod and the applicator are connected by one of their
-9 ends.
First embodiment: Figures 2A to 2D
The applicator
The applicator 100 described in this embodiment comprises thirteen groups 10 of protuberances 11. Each group of protuberances comprises an identical number of protuberances 11, namely thirty in this case. It can of course be provided for the groups 10 of protuberances to include different numbers of protuberances 11 between them.
In this embodiment, the groups 10 form three sets 13 of groups. Each set 13 is composed of four groups 10 of protuberances. It can of course be provided that the applicator comprises a higher or lower number of sets 13 and that these sets are composed of a higher or lower number of groups 10 of protuberances. It can also be provided that the assemblies 13 are not all composed of an identical number of groups 10. The groups 10 of the various assemblies 13 are aligned along the longitudinal axis 9 of the applicator. It can of course be provided that the groups of the different assemblies are offset with respect to each other along the longitudinal axis 9 of the applicator. The groups thus form four straight rows of groups, the rows being parallel to the axis
9. They also form three circular rows in planes perpendicular to the axis, which constitute the sets.
Within a single assembly 13, the groups 10 are the images of each other by a rotation of 90 ° around the longitudinal axis of the applicator. It is of course possible to provide for this rotation to be greater or less, for example greater than 100 ° or less than 80 °, or even greater than 120 ° or less than 60 °, or even more than 150 ° or less than 40 °. It can also be provided that none of the groups 10 of protuberances of the same set 13 is the image by rotation of another group 10 of the same set.
The main axes 14 of the groups 10 of protuberances of the same assembly 13 are all located in the same plane (see FIG. 2A). The groups 10 of the same assembly 13 are spaced only at an angle of 90 ° relative to the longitudinal axis 9 of the applicator. Thus, the main axes 14 of two groups located on either side of the applicator are combined. The main axes of two groups 10 which are directly followed by turning around the longitudinal axis of the applicator are perpendicular.
The three planes in which the main axes 14 of the groups 10 of the three assemblies 13 of the applicator are located are parallel to each other (see FIG. 2C). We can
-10 of course provide that only some of these planes are parallel to each other.
In this case, these planes are perpendicular to the axis 9 of the applicator. It can of course be provided that none of the planes is perpendicular to this axis, or that some of these planes only are.
There is a plane of symmetry between the sets 13 of the applicator. In this case, there is a plane of symmetry between each pair of consecutive sets along the axis of the applicator. It can be expected that there will be a plane of symmetry between certain only of the sets 13 of the applicator 100.
The bases of the protuberances 11 of the same group form a closed loop 12. With the exception of group 10 located at the free end of the applicator 100, the loop 12 of the groups is not crossed by the longitudinal axis 9 of the applicator. With regard to the group located at the free end of the applicator, its main axis coincides with the longitudinal axis of the applicator.
The loops, other than the group 10 loop located at the free end of the applicator, are all identical to each other. They have a generally oblong shape (see Figure 2C) and each extend in a plane parallel to the axis 9. The loop 12 of group 10 located at the free end has a diamond shape (see Figure 2A ). Of course, provision can be made for the loops to have different shapes. We can also provide that all the loops are different from each other.
The direction of the largest dimension of the loops 12 is parallel to the longitudinal axis 9 (see Figure 2C). We can of course provide that this is not the case and that this direction is inclined at an angle between 5 ° and 90 °, for example between 15 ° and 80 °, or even between 30 ° and 60 °, or even era 40 ° and 50 °.
The loop 12 of any group 10, except that of the end, delimits a central opening 15 passing right through the applicator. In the present case, each group has a central opening 15 passing right through the applicator until the opening of the diametrically opposite group. It can of course be provided that only a few groups have a central opening 15 passing right through the applicator. It can also be expected that none of the groups has such an opening.
In a particular embodiment, provision may be made for at least some of the central openings 15 of the groups, or even all the central openings 15, to be partially closed by a mesh or trellis.
In the present case, the applicator comprises a hollow core such that all of the central openings 15 of the applicator communicate with each other, in particular along the axis 9. It can of course be provided that at least certain of these openings control panels 15 do not communicate with others.
-11The walls of the core are full but we can predict that this is not the case. For example, one can consider a wall which is perforated, thus forming a mesh or trellis or an exoskeleton structure.
The protrusions 11 of a group 10 of protrusions are all identical. They are rectilinear, elongated and their thickness decreases appreciably from their base towards their end. They extend from the loop 12 delimited by their base towards the outside, that is to say in a direction which moves away from the longitudinal axis 9 of the applicator 100. They are arranged in an ordered row going around the loop 12 and thus form a crown. In the present case, all the groups 10 of protrusions 11 of the applicator 100 form a crown. This arrangement can also be designated as a flower or corolla configuration. The protuberances of a group all have a flared envelope surface.
There are several planes of symmetry within the same group 10 of protuberances
11. There is in particular a plane of symmetry comprising the direction of the largest dimension of the loop 12 and another plane comprising the direction of the smallest dimension of the loop 12. It can be provided that the protrusions have a different shape, for example example curved or wavy, even conical and / or hollow.
The protuberance groups are carried by a support 16. This support 16 is formed by a bulge in the core of the applicator. In the present case, each group 10 of protuberances is carried by such a support 16. It can of course be provided that none, or only some, of the groups is carried by a support 16. It can be provided that the supports are not distinct of the applicator's soul.
Using the applicator
At first, the user manipulates the applicator 100 while holding the cap 3 between her fingers and immerses the applicator 100 in the mascara reservoir 5 of article 2. During this step, the protrusions 11 are loaded with mascara.
The applicator, when it leaves the reservoir, passes through the wiper 6 and the protrusions 11 are thus wrung out so as to leave only the quantity necessary for making-up on the latter and in this way avoiding the formation of "packets". There is also mascara on the body of the applicator between and in the center of the different groups.
During use, the user approaches the applicator of her eyelashes in order to make up them and uses a classic makeup movement, essentially vertical. The mascara present on the protrusions 11 is thus deposited on the eyelashes. In the same movement, these protrusions make it possible to smooth the deposited mascara as well as to comb the eyelashes. In the present case, there are three zones of lashes for a row of eyelashes.
-12 makeup along the applicator 100 which correspond to the three groups 10 aligned along the longitudinal axis 9 of the applicator which make it possible to obtain a makeup effect by zone.
In addition, the fact that the core is hollow makes it possible to give the applicator a certain flexibility which makes the application of the mascara more pleasant for the user.
The group of protuberances located at the free end of the applicator allows more precise makeup of the eyelashes, for example on a reduced area, and is therefore particularly useful for touching up makeup.
Second embodiment: Figures 3A to 3C
We will now describe a second embodiment of the applicator according to the invention, usable in the article in FIG. 200.
The applicator of this embodiment differs from the applicator of the first embodiment in several respects. We will only describe the differences between this embodiment and the previous one.
First, the soul of this applicator 200 is perforated between the groups. This characteristic makes it possible to give the applicator greater flexibility and therefore to make the makeup more pleasant for the user. The soul includes a large number of holes in this case. This number is greater than one hundred, for example greater than two hundred, or even greater than three hundred. This large number of holes gives the soul a mesh or trellis structure, or even an exoskeleton type structure. The different orifices can have different sizes and shapes. They have for the most part irregular general forms appreciably circular or oblong. Of course, other shapes can be envisaged, for example general shapes of polygonal type.
In this embodiment, the applicator 200 comprises thirty-seven groups 10 of protuberances 11. These groups are divided into nine assemblies composed of four groups 10 each as well as one group located at the free end.
There are two types of assemblies, namely assemblies 13 of a first type in which the groups 10 are carried by supports 16 and assemblies 17 of a second type in which the groups 10 are not carried by supports 16 (see Figure 3A to 3C). In the present case, the applicator comprises five sets 13 of the first type and four sets 17 of the second type. The loops 12 as well as the protuberances 11 of the groups 10 of these assemblies 17 are of smaller dimension than those of the other assemblies 13.
These types of assemblies 13, 17 are alternated when one traverses the applicator from its proximal end to its free end. This feature allows
The applicator to understand a greater number of sets 13, 17 and to have a higher density of protuberances.
In addition, these types of assemblies are staggered by reference to their angular position around the axis, that is to say when looking at the applicator in end view. In this way, the groups associated with the first type are not aligned with those of the second type parallel to the axis and even extend between two groups of the second type.
It can of course be expected that there will be a different number of sets 13, 17 and / or that these will be composed of a different number of groups 10 of protuberances 11.
Another difference compared to the first embodiment lies in the fact that the protuberance groups are composed of a double row of protuberances 11. This characteristic also makes it possible to increase the density of protuberances 11 of the applicator 1. It is possible to provide that groups 10 are composed of more than two rows of protrusions, for example three, four or five. It can be provided that the different rows of protrusions 11 of the same group 10 are composed of the same number of protrusions. It can also be provided that the number of protrusions of the different rows is different.
The loops 12 of the different groups 10 of this applicator delimit each of the central openings 15 which are partially closed and form a mesh or trellis or an exoskeleton structure similar to that of the core of the applicator. The central openings 15 of all the groups 10 of protuberances communicate with each other. This applicator comprises groups with loops 12 which can be oblong or circular with values of larger and smaller dimensions which can vary between the different loops.
When looking at the applicator from its free end, the entire periphery of the applicator is occupied by protuberances 11 from groups 10 of the different sets 13, 17. And as we have seen, groups 10 from protuberances of two sets following one another along the applicator are angularly offset around the longitudinal axis 9 of the applicator.
The use of this applicator is similar to that of the applicator of the first embodiment with the difference that there is a greater number of makeup zones and that different makeup effects are obtained depending on whether the group 10 of protrusions which make up the eyelash is carried by a support 16 or not. This last characteristic makes it possible, for example, to create differences in the curvature of the eyelashes and to give the row of eyelashes an undulation which constitutes a particularly sought-after makeup effect.
-14Third embodiment: figure 4
This embodiment differs from the second embodiment only in that the applicator 300 does not include assemblies 17 of the second type, namely whose groups 10 are not carried by supports 16 (see FIG. 4). The density of groups and protuberances is therefore reduced.
The use of this applicator is similar to that described for the first two embodiments.
Fourth embodiment: FIGS. 5A to 5E
The applicator 400 of this embodiment differs from the applicator of the first embodiment in several respects.
With reference to FIGS. 5A to 5E, this applicator comprises two main types of groups 10, 18 of protuberances 11.
A first type of groups 10 of protrusions is similar to those presented in the first embodiment. The groups 10 of protrusions of this type are carried by a support 16 (see FIG. 5C).
The second type of groups 18 of protuberances is particular in that the loop 12 formed by the protuberances is more elongated and is partially wound around the longitudinal axis 9 of the applicator. This winding causes the group 10 of protrusions 11 to wind around this same axis. The winding range of a group 18 around the axis of the applicator is 180 ° in the present case. It can be expected that this range is between 20 ° and 350 °, preferably between 180 ° and 300 °. These groups 18 have a general helical shape.
The groups 10, 18 of protuberances of the same type are all identical to each other and are aligned along the longitudinal axis 9 of the applicator.
The loops 12 of all the groups 10, 18 are non-planar. It can of course be expected that this is not the case for groups other than those which wrap around the longitudinal axis 9 of the applicator.
In the present case, the applicator comprises four groups 18 of protuberances of the second type (wrapping around the longitudinal axis 9) and four groups 10 of protuberances of the first type. In the embodiment presented in FIGS. 5A to 5E, the most distal group 18 of protuberances is truncated so that its loop is not closed.
In this embodiment, the applicator comprises two sets 19, 20 of groups 10, 18 of protuberances. In these sets 19, 20, the groups 10, 18 are aligned along the longitudinal axis 9. The main axes of the groups of these two sets are included in the same plane, this plane also comprising the axis
-15longitudinal 9. It is of course possible to provide for a greater number of sets. It can also be expected that these sets are composed of a smaller or larger number of groups.
The loops 12 defined by the groups 10, 18 of protrusions all delimit a central opening 15 through. All the openings 15 communicate with each other.
The largest dimension of the loops of the different protuberance groups is inclined relative to the longitudinal axis of the applicator. This inclination is between 5 ° and 90 °, for example between 15 ° and 80 °, between 30 ° and 60 °, or even between 40 ° and 50 °. It can of course be provided that the large dimension folds of these loops 12 is parallel to this axis.
The manufacturing process
The applicators presented above are here made in one piece. More particularly, these applicators are here produced by additive synthesis, also called three-dimensional printing.
Any suitable material is suitable for making these applicators. This can be a plastic material, for example a polyamide, in particular a polyamide 1102, a PEBA 2301, or else an ABS type resin, or even a powdered metal such as stainless steel or titanium.
The material may be rigid but will preferably be elastically flexible. It is preferable that the material, in combination with the shape characteristics of the applicator, gives it a certain flexibility.
Remember that a mascara applicator generally has a length of less than 20 mm.
Several additive synthesis methods can be used for the production of an applicator as described above. Mention may in particular be made of selective laser sintering from powdered material and stereolithography (SLA). In the present case, a selective laser sintering method is used, this method having the advantage of allowing the manufacture of objects having a complex shape.
The applicator is initially designed using computer-aided design (CAD) software. A file in STL format including the design data of the applicator thus designed is then exported. This data determines the shape of the applicator. Other standard file formats for additive synthesis can be used.
This file is then processed by software supplied by the manufacturer of the machine used to perform the additive synthesis. This software cuts into sections the file in the form of a hundred digital images in SLI or BFF format, each of them
-16corresponding to a layer of the model to be printed, that is to say to a section of the applicator taken in a plane perpendicular to the longitudinal axis of the applicator 9. These data are then transmitted to the printer in order let her produce the applicator.
Once the synthesis is complete, treatments can be applied to the applicator 5 in order, for example, to improve its appearance.
Of course, many modifications can be made to the invention without departing from the scope thereof.
The embodiments presented above relate to the mascara applicators 10 and the eyeliners, but these characteristics can be applied to other types of cosmetic product applicators such as nail polish, lipstick, or cosmetic product for eyebrows or hair.
