Description

Title of the invention: Cosmetic applicator technical field

[0001] The present invention relates to applicators for applying a cosmetic, makeup or skincare product to human keratinous materials, in particular skin, lips or keratinous fibers such as eyelashes and / or eyebrows, and packaging and application devices comprising such applicators.

[0002] The invention relates more particularly to applicators comprising an application element made at least partially, or better yet totally, of plastic material, in particular of at least one thermoplastic material by injection molding.

[0003] The invention relates both to "dip-in" type conditioning and application devices, i.e., comprising an applicator and a reservoir into which the applicator is immersed to be loaded with composition, and to "flow-through" type devices in which the application element is supplied with composition by a device to which it is attached during application, such as a dispensing pen equipped with a composition dispensing mechanism, a compressible-walled container, or the like. Prior art

[0004] Dip-in type applicators used for eyelash or eyebrow makeup usually include an application element mounted at the end of a rod, the latter being connected at the other end to a gripping element, which also serves as a closing cap for the container containing the product.

[0005] The application member is conventionally loaded with product by being immersed in the container, which is provided with a wringer which has a lip to wipe the rod when it is extracted from the container and which generally defines an orifice of substantially circular cross-section whose diameter is adapted to that of the rod.

[0006] The behavior of the application member when passing through the wringer depends on many factors such as the shape and nature of the wringer lip as well as its dimensions, the geometry of the application member and the choice of the material or materials which constitute it.

[0007] Excessively vigorous wringing of the application element is likely to cause difficulty in extracting it from the container, and makes the application element very unloading, which forces the user to frequently re-dip the applicator into the container and may hinder the achievement of certain makeup effects.

[0008] Conversely, insufficient wringing leaves an excess of product on the application device which is difficult to distribute on the eyelashes and can lead to the presence of product clumps on the eyelashes, which are thus poorly separated.

[0009] Furthermore, the application member generally carries application elements consisting of pins whose arrangement influences the behavior of the applicator when it is extracted from the container and the resulting load.

[0010] Very flexible bristles will easily deform as they pass through the wiper, thus facilitating its removal, but their flexibility makes it more difficult for them to properly comb the eyelashes during application and to smooth the product on their surface. Furthermore, the wiper will tend to leave less product on the applicator.

[0011] Conversely, more rigid bristles will tend to deform less as they pass through the application device, leading to a greater loading of the application device with product and a better ability to comb and separate the lashes. However, they can make it more difficult for the device to pass through the wiper and result in a loss of sensory sensitivity during application.

[0012] The design of the applicator thus most often results from a compromise that must be found between various, sometimes contradictory, requirements concerning the quantity of product that is left on the application organ for makeup, the desired behavior when removing the application organ and the ability to separate eyelashes.

[0013] Conventionally, the pins are carried by a central core of the application member. However, application members have been developed in which the pins are carried by flexible arms.

[0014] French application FR3039382 describes an applicator comprising an elongated rod carrying an application member extending along a longitudinal axis. This application member has a core with one or more through openings. Branches connect at one end to the core and meet through said opening. In some embodiments, the branches form several successive loops that are connected to each other at the opening(s) in the core. In another embodiment, the application member has a single loop connected at its ends to a support portion adjacent to the rod. The apex of the loop is located in the opening, bearing axially against an adjustment pin that slides longitudinally in a distal portion of the core. Thus, by pushing the adjustment pin in more or less, it is possible to deform the loop and modify the properties of the applicator.

[0015] Application FR2993151 describes an application element for eyelash makeup, having a core with swollen portions extending around cavities.

[0016] Application EP2654490 discloses application elements comprising branches in the form of outwardly convex arches, arranged around a central core.

[0017] Application WO2023 / 233044 describes an application member comprising a plurality of branches having a twisted shape and connected to each other at their distal end.

[0018] US2021 / 0186183A1 describes an application member comprising a core connected at one end to a support portion carried by a mounting end in an applicator rod. The core comprises a first portion extending forward and a second portion forming a return whose free end is located near the support portion. This return has arches through which the first portion of the core passes.

[0019] Such an application element has a relatively complex structure, not suitable for manufacturing by injection of thermoplastic material.

[0020] US patent 6655390 describes an eyelash makeup applicator comprising a perforated support carrying teeth, these connecting either directly to the support or to arches carried by the support.

[0021] Moreover, makeup for the skin, nails or lips generally poses problems of precision of application, autonomy of the applicator and comfort of use, whether the applicator is of the "dip-in" or "flow through" type.

[0022] It is common practice to flock the application element in order to capture the composition and make it easier to spread. However, the flocking operation is relatively complex and involves the use of adhesives, which do not always provide the necessary mechanical strength under certain conditions of use.

[0023] Patent EP1726235B1 describes a flocked application element having several branches.

[0024] Application FR2722381 describes a nail polish applicator comprising an application element formed by a flocked flexible loop.

[0025] Finally, it is known in particular from US9277800 and US8096306 to give the envelope surface of an application element provided with pins a shape passing through a minimum cross-section in an intermediate zone, by playing on the length of the pins and / or the cross-section of the core carrying the pins.

[0026] The bristles located in the area of ​​smallest cross-section of the coating surface tend to be less tightly wrung and more heavily loaded with composition. However, having shorter bristles can reduce the effectiveness of engagement with the cilia. Furthermore, the core generally does not have a large diameter, which makes it difficult to vary the cross-section of the coating surface simply by changing the core's dimensions. Description of the invention

[0027] There is a need to further improve cosmetic applicators and in particular to remedy all or part of the drawbacks encountered in the prior art.

[0028] There is a need for an application element that has both good cilia loading and separation properties.

[0029] There is also an interest in having an application device with satisfactory performance, which, when the applicator is used with a container equipped with a wringer, promotes the renewal of the product during a cycle of extraction and reinsertion of the applicator into the container, and whose mechanical properties can be modified relatively easily during the design, to adapt to the rheology of the product and the desired makeup.

[0030] There is still an interest in having an application element suitable for manufacturing by injection molding in thermoplastic material, which is less expensive to implement than additive manufacturing.

[0031] There is also a need for an applicator suitable for applying a composition to the skin or lips, which is comfortable to use and allows the presence of flocking to be avoided if desired, while retaining sufficient capacity to capture the composition.

[0032] It would also be useful to have an applicator that facilitates positioning on the lower lip or on another facial feature during application, and / or has a higher composition load. Summary of the invention

[0033] The invention aims to meet all or part of these needs, and it achieves this by proposing an applicator comprising: - An application element extending along a longitudinal axis, comprising: - at least a supporting part, - at least one initial structure comprising at least two branches opposite ends connected at one end to the support part and connected to each other at the opposite end, - at least one second structure comprising at least two opposing branches connected at one end to the support part and connected to each other at the other end, thus forming a loop, this loop passing through the gap between said branches of the first structure, - at least one of the branches of the first and second structures exhibiting a succession, along the branch, of at least one portion convex outwards, a portion concave outwards, then a portion convex outwards.

[0034] The presence of the concave portion between the convex portions allows for less wringing of the application element in this area, and a greater composition load. The reduced distance of the branches from the longitudinal axis in this area also allows for longer application elements, better suited to separating the cilia.

[0035] In cases where the application device is intended for applying a composition to the skin or lips, the aforementioned concave portion can facilitate its positioning on the lower lip, or another facial feature. The alternating convex and concave portions also provide a larger surface area, resulting in a greater load.

[0036] All branches of the first structure can exhibit symmetry with respect to the longitudinal axis of the application member, which is rectilinear in this case.

[0037] All branches of the second structure can exhibit symmetry with respect to the longitudinal axis of the application member, which is rectilinear in this case.

[0038] Only the first or second structure may have branches exhibiting said succession of convex and concave portions. The branches of the first and second structures may then advantageously alternate around the longitudinal axis of the application member. This can allow for an alternation of more or less densely packed areas in the circumferential direction, which can make it possible to find a good compromise between the density of the cilia and separation.

[0039] Thus, in embodiment examples, the branches of the first structure have an arched shape convex outwards, and the branches of the second structure have said succession, in particular a wavy shape, while alternating with those of the first structure.

[0040] In other embodiments, both branches of the first and second structure each exhibit said succession, in particular a wavy shape.

[0041] When all the branches are thus wavy, this can give the envelope surface of the application organ a general peanut shape, for example.

[0042] Such an application element then makes it possible to have, in particular when used in connection with a container having a wringer, a reserve of composition on the application element, in particular in its middle region which can be of smaller diameter due to the hollow portions of the branches, while having more wrung-out areas due to the convex portions of the branches.

[0043] The outwardly concave portion may be rounded. Alternatively, the outwardly concave portion may be U-shaped. The concave portion may also have other shapes, for example V-shaped.

[0044] The length of the application elements may be constant along the convex and concave portions or may vary. The arms may thus carry application elements such as pins, with application elements carried by at least one of the convex portions being shorter than those carried by the concave portion. The length of application elements such as pins ranges, for example, from 0.1 to 5 mm.

[0045] The first structure can form a cage defining the distal end of the application member. Alternatively, the distal end of the application member is defined by a distal part which is, for example, cylindrical or conical in shape, with a circular cross-section.

[0046] The application member may thus include a distal part, in particular of symmetrical shape of revolution, the branches of the first structure serving to connect the support part to the distal part.

[0047] The arms of the first structure may or may not be connected to those of the second structure, particularly in a median region of the application member. This connection is preferably made using connecting elements radially internal to the arms. Such connecting elements are preferably arranged to butt against each other when the arms are pressed radially inwards. This can limit the radial deformability of the application member as it passes through the wringing member.

[0048] The first and / or second structure may include branches which are twisted around the longitudinal axis of the application member.

[0049] The first and second structures can be flexible. By "flexible" it is understood that the branches or loops can deform during application and / or passage through the wringing element, in the presence of such a wringing element.

[0050] The second structure may have a loop engaged through the branches of the first structure, having a single vertex, for example centered on a median plane containing the longitudinal axis of the application member.

[0051] The loop of the second structure, by passing through the gap between the branches of the first structure, at least partially occupies the space between the branches and thus forms capillary traps between the branches and the loop, between the branches, and within the loop, provided the viscosity of the composition allows it. A wide variety of application surface configurations can be obtained, suitable for applying makeup to smooth surfaces such as skin or lips, or to fibers such as eyelashes, in the presence of textured surfaces such as bristles on the applicator.

[0052] When the application element has application features such as bristles or other raised areas and is intended for eyelash and / or eyebrow makeup, the flexibility of the arms facilitates their deformation as they pass through the wiper, which allows, on the one hand to reduce the constraints on the bristles, and on the other hand to create internal movements of composition promoting its renewal, especially from the inside out.

[0053] The flexibility of the arms provides comfort during application, and their elasticity allows the applicator to retain its shape, facilitating precise makeup application. The proximity between the arms, or between the arms and the loop, can create capillary traps, as mentioned above, when the viscosity of the composition allows, enabling the product to be absorbed and thus eliminating the need for flocking. This simplifies the applicator's manufacture and avoids the compatibility and adhesion constraints of flocking in the presence of solvents that may be present in the composition.

[0054] In examples of implementations of the invention, the application member can be manufactured by injection molding of a single-piece thermoplastic material, which reduces manufacturing costs compared to additive manufacturing. This can also facilitate the use of recyclable or recycled plastics. The application member can be molded from a thermoplastic material chosen, for example, from thermoplastic elastomers, SEBS, TPE, Hytrel® (thermoplastic elastomer copolyester), TPV, PE, LDPE, HDPE, etc.

[0055] The application member can be molded from a thermoplastic material having a Shore hardness ranging from 30 Shore A to 72 Shore D.

[0056] The application element is preferably made by injection molding of thermoplastic material, but it can be made by other means when its shape does not allow it, in which case it may be made, for example, by an additive manufacturing technique. Application element

[0057] The application member can be mounted on the end of a rod to be inserted into a container equipped with a wringer and to be loaded with composition.

[0058] Alternatively, the application element is fed directly from the container via a feed channel. In this case, the device does not include a wringer. This variant is more suited to an application element intended for application to the skin, lips, or hair.

[0059] The application member may include a mounting tip for an applicator rod; this tip may have a circular cross-section with a constant diameter or a diameter decreasing towards the proximal end of the application member. The tip may form a shoulder with the support portion, the contour of which may be circular, with a diameter corresponding to the outer diameter of the applicator rod. This shoulder may abut against the rod during the mounting of the application member.

[0060] The mounting tip can be filled.

[0061] The support part may have a length that may be less than a quarter of the length of the apparent portion of the application member, that is to say in the presence of the aforementioned shoulder, of the length extending between the distal end of the application member and this shoulder.

[0062] The support part can also be longer, in particular to occupy the central space of the application member and to allow the formation of capillary traps with branches of the first and / or second structures arranged around it.

[0063] The support portion may have bristles when the applicator is intended for applying a composition to keratin fibers such as eyelashes. The bristles are, for example, arranged in rows located in line with bristles on branches of the first and / or second structures.

[0064] The distal end of the application organ can be defined by the first structure.

[0065] Alternatively, the distal end of the application organ is defined by a distal part which extends between the distal end of the application organ and the branches of the first structure, as previously mentioned.

[0066] Such a distal part may be solid, and of cross-section for example circular, the distal part being able to have a longitudinal axis coinciding with the longitudinal axis of the support part and that of the tip.

[0067] The application device may be intended for applying the composition to a continuous surface, such as the skin or lips, or a discontinuous surface, such as keratin fibers, in particular eyelashes and / or eyebrows.

[0068] In the case of application to a continuous surface, the application element is advantageously flock-free. The flexibility of the arms, their shape, and their proximity can sufficiently retain the composition by surface tension, making such a flocking coating unnecessary. This simplifies the manufacture of the applicator and improves its reliability, as it is not necessary to ensure the resistance of the adhesive used to bond the flock fibers to the composition and the forces exerted during wringing or use.

[0069] When used to apply a composition to keratin fibers, the application device may have application features such as spikes or other raised features, which may be located on all or only a portion of the application device. "Spot or other raised feature" refers to any identifiable protrusion suitable for applying the composition to eyelashes and / or eyebrows, and in particular, capable of engaging between the eyelashes and / or eyebrows.

[0070] The aforementioned distal part can thus carry such application elements, when the applicator is intended for application on keratin fibers such as eyelashes.

[0071] The length of the distal part can then correspond to more than a quarter of the apparent length of the application organ.

[0072] These studs can be arranged in rows which are for example aligned with rows of studs carried by branches of the first and / or second structures.

[0073] In the presence of a distal portion, the first and second structures can act as a joint, allowing the distal portion to easily change its orientation relative to the axis of the support portion, for example, under pressure exerted during application. By choosing the configuration of the branches of the first and second structures, particularly by having a non-homogeneous distribution of the branches around the longitudinal axis of the application member, it is possible to enhance the deformability of the first and second structures around certain pivot axes. This can improve the applicator's behavior when applying the composition using specific areas of the application member.Alternatively, the first structure provides the connection between the supporting and distal parts with at least three branches equidistant angularly around the longitudinal axis of the application organ, which ensures homogeneous behavior of the connection in all directions.

[0074] The first and second structures may include branches that connect to the support part along a corresponding radial plane, at an angle with the longitudinal axis of the application member, this angle ranging, for example, from 0 to 90°, preferably between 0 and 60°. Such a preferential orientation of the branches can facilitate passage through the wringer.

[0075] The first and / or second structures may have branches having in cross-section a shape suitable for their demolding in an injection molding manufacturing process, in particular branches which in cross-section have straight sides diverging outwards, joined by a convex rounding outwards.

[0076] The applicator may consist, for defining the application surface of the composition, only of the application element, which may be a single piece. The application surface may thus be unflocked.

[0077] The application element can be made without the possibility of adjusting its configuration, unlike that described in the aforementioned FR3039382 application, and in particular without an element that can be fixed in one of two predefined positions. First structure

[0078] The first structure mentioned above can be formed by a free loop, the two branches joining at the distal end of the application organ, the two ends of the branches opposite the top of the loop being connected to the support part.

[0079] This loop can extend in the axial direction, in particular along a plane, which preferably contains the longitudinal axis of the support part.

[0080] The first structure may also have more than two branches, thus forming for example a cage, the branches being connected at one end to the support part and joining each other at the opposite end, which may define the distal end of the application organ.

[0081] The first structure may have an even number of branches greater than two, for example four or six, two by two diametrically opposed, two opposite branches forming a loop extending preferably in a plane containing the longitudinal axis of the application member.

[0082] The first structure may have axial symmetry with respect to the longitudinal axis of the application member, or only symmetry with respect to a median plane, or even be without any symmetry.

[0083] The first structure may have a length that corresponds to more or less half of the apparent length of the application member.

[0084] The first structure can define the distal end of the application member or serve to connect the support part to a distal part of the application member, which is for example solid or carrying another application element such as a twisted-core brush.

[0085] The distal part may thus comprise a solid or hollow central body, with or without a circular cross-section, centered on the longitudinal axis of a tip of the application member used for attachment to the applicator stem. The largest diameter of the distal part corresponds, for example, approximately to that of the support part.

[0086] The length of this distal part may or may not exceed that of the first structure.

[0087] The distal part may have a straight longitudinal axis aligned with that of the support part.

[0088] The first structure may have branches exhibiting at least one undulation, in particular several identical undulating branches, giving, for example, the first structure a general peanut shape, as mentioned above.

[0089] The arms of the first structure can be connected to those of the second structure, particularly in a median region of the application member; this connection is made, for example, by means of connecting elements radially internal to the arms. Such connecting elements can be arranged to butt against each other when the arms are pressed radially inwards, as may be the case when passing through the wringer. This allows for a stronger scraping of the surface of the application member by the wringer.

[0090] The first structure may include branches which are twisted around the longitudinal axis of the application member, these branches being in examples joined at the distal end of the application member.

[0091] The first structure may comprise a cage having several branches defining an envelope surface whose diameter increases from the support part, passes through a maximum near the support part, and decreases to the distal end of the application member. Such a cage may thus have a profile in the general shape of a "teardrop".

[0092] When the first structure defines an outer cage, having several branches, these can connect together at the distal end of the application member according to a cross or a star, the branches connecting to each other at the distal end of the application member for example according to a cone converging towards the distal end; this allows to have a finer application tip at the distal end of the application member.

[0093] The first structure may comprise loops located on either side of a median plane of symmetry containing the longitudinal axis and perpendicular to a median plane of symmetry for the application member. Each of these loops may comprise two branches having a wavy shape, with a succession of a convex portion, a concave portion, and a convex portion, going from the proximal end to the distal end of the application member.

[0094] The application member may include at least one membrane carried by at least one of the branches.

[0095] Such a membrane can be thinner than the strand of material constituting the branch to which it is connected, in particular more than half, or even more than three or four times thinner, which allows the membrane to retain its flexibility and not unduly hinder the deformation of the branch. Second structure

[0096] The second structure can be formed of a single loop, extending for example in a plane containing the longitudinal axis of the application member.

[0097] The second structure may have more than two branches, forming, for example, a cage, the branches being joined at one end, in particular four branches, preferably two diametrically opposed. The presence of a cage may provide greater mechanical strength to the branches and the application member.

[0098] These four branches can form two loops joined at the distal end of the cage, extending along two respective planes perpendicular to each other.

[0099] The branches may each have at least one undulation, each loop formed by two opposite branches having for example a general peanut shape when viewed from its plane, as mentioned above.

[0100] When both the first and second structures comprise cages having several branches joined at one end, the two cages are advantageously angularly offset from each other around the longitudinal axis of the application member by an angle equal to 360° / n, where n denotes the total number of branches. Preferably, each cage comprises the same number of branches, in particular four branches.

[0101] Alternatively, when both the first structure and the second structure comprise cages having several branches joined at one end, the cages are not angularly offset from each other, the branches of the innermost cage being each located in the same plane as at least one branch of the outermost cage.

[0102] The second structure may include a loop which is internally stiffened by a lattice-shaped structure, in particular a rhombus, connected both to a median area of ​​the opposite branches of the loop, to the top of the loop and to the support part.

[0103] The second structure may include a cage whose arms define, in a central area, a notch open to the outside. Such a notch may allow, when the application member has pins, for example, longer pins that connect at their base to the bottom of the notch.

[0104] The second structure may comprise a cage whose arms are twisted around the longitudinal axis of the application member. Such a twisted shape may improve the grip of the eyelashes when the arms bear prongs.

[0105] The second structure, like the first, may have studs or other raised features when the application member is intended for the application of a composition to the eyelashes and / or eyebrows. Additional structure

[0106] The application member may include an additional structure, distinct from the first and second structures.

[0107] This additional structure may include at least one loop, connecting at its ends to the support part, and extending in a plane containing the longitudinal axis of the application member, preferably distinct from those in which the branches of the first and second structures extend.

[0108] The presence of this additional structure creates an additional surface for capturing the composition, and can carry application elements such as bristles, when the application organ is intended for eyelash and / or eyebrow makeup.

[0109] The additional structure may include at least one loop passing through an opening defined by a loop of the first structure. Branches

[0110] The first and second structures include flexible branches that can form loops or cages.

[0111] A loop may have two ends connected to the support part. These two ends may be connected to a surface which may be a surface of revolution of the support part or the same flat surface, for example a flat surface perpendicular to the longitudinal axis of the application member.

[0112] A cage can be formed of at least three branches, preferably an even number of branches, for example 4 or 6.

[0113] The branches may have a circular or other cross-section, and preferably the branches have a cross-section suitable for manufacturing by injection molding of the application member.

[0114] The branches may in particular have a contour of symmetrical shape with respect to a median plane for the section, this contour being formed, on each side of this median plane, by the union of two substantially straight segments starting from a vertex, diverging outwards, and a rounded joining said segments.

[0115] Such a cross-sectional shape can facilitate the extraction of the mold used for injection molding, and thus limit the risk of damage to the application member during its extraction during demolding.

[0116] Preferably, two opposite branches of the same structure have, on the same side and in the same plane of section perpendicular to the longitudinal axis of the application member, segments that are parallel to each other. This can facilitate the removal of the molds used for shaping the application member.

[0117] A branch can have a cross-sectional area of ​​between 0.01 and 20 mm², or more preferably between 0.2 and 5 mm². Its largest transverse dimension (i.e., the diameter in the case of a branch with a circular cross-section) can range from 0.1 to 4 mm, for example. The extended length of a branch, between its connection end to the support part and its opposite end, for example the distal end of the loop or cage to which this branch belongs, ranges, for example, from 3 to 60 mm.

[0118] The application member can be inscribed in section in a circle with a diameter ranging from 4 to 12 mm for an applicator intended for application on eyelashes or eyebrows, and a circle ranging from 4 to 17 mm for an applicator intended for application on lips.

[0119] The arms may carry, on at least part of their inner circumference, a thinner membrane, for example with a ratio ei / e2, where ei denotes the thickness of the arm and e2 that of the membrane, greater than 2, better than 3, and even better than 4. Such a membrane can facilitate the production of the application member by injection molding, by extending into the parting line. Regardless of this The advantage is that the membrane can also increase the surface area available to retain the composition, without unduly affecting the flexibility of the branches.

[0120] The term "loop" refers to a branch or series of branches that, together with one or more other parts of the application member, form a closed contour surrounding an interior space distinct from the branch(es). The loop may extend along a single plane, which contains the longitudinal axes of the branches. Alternatively, the loop may not extend along a single plane. The loop may be symmetrical or asymmetrical with respect to a median plane. The loop may have the ends of its constituent branch(es) located on the support part at the same axial position along the longitudinal axis of the application member. The branch(es) constituting the loop may extend angularly around a point located in the aforementioned interior space, at an angle of at least 120°, preferably at least 180°. Conditioning and application device

[0121] The invention also relates to a conditioning and application device comprising: - An applicator according to the invention, - a container containing the mixture to be applied.

[0122] The container may include a wringer through which the application member passes when it is extracted from the container. Alternatively, the applicator is mounted on the container, which directly supplies the application member with the composition.

[0123] The orifice defined by the wringer, in particular its diameter, can be dimensioned in such a way that the first and / or second structures deform when passing through it. For example, the largest diameter of the application element (i.e., the diameter of the largest circle circumscribed about the cross-section of the application element) is between 1 and 2 times, or even between 1 and 1.5 times, the diameter of the wringing orifice (i.e., the diameter of the smallest circle circumscribed about the inner cross-section of this orifice).

[0124] For example, we have the wringing element which defines a wringing orifice of radius R, the application element having branches whose hollow of the concave portion is located at a minimum distance Rlmin greater than, equal to or less than R, and the apex of at least one convex portion, at a distance R2max greater than or equal to R.

[0125] In the case where the hollow of the concave portion is located at a minimum distance Rlmin less than R, the hollow area of ​​the concave portion is not scraped when passing through the wringing element and advantageously forms a reserve of composition on the applicator, thus increasing its autonomy.

[0126] The composition contained in the container may be a makeup or skincare product, in particular a makeup or skincare or lip care product, or a mascara. Makeup process

[0127] The invention further relates to a method of making up human keratinous materials, in particular skin, lips, eyelashes or eyebrows, by means of a conditioning and application device as defined above, this method comprising the step of applying the composition to the keratinous materials using the applicator.

[0128] The method may include rotating the application element around its axis, particularly when unscrewing the applicator previously screwed onto a threaded neck of the container, to twist the first and / or second structures upon contact with the wiper and tighten them radially. This can create forced circulation of the composition, thus promoting its renewal and improving wiping. In cases where the composition is relatively viscous, such as with mascara, the application element may tend to twist upon contact with the composition when unscrewing the container's closure, which also serves as the applicator's gripping element.

[0211] [Fig.82] [Fig.82] is a longitudinal section along LXXXII of [Fig.81].

[0212] Figure 1 shows an example of a conditioning and application device 1 made according to the invention, comprising an applicator 2 and an associated container 3 containing a product P to be applied to human keratinous materials, for example eyelashes or eyebrows, or alternatively skin or lips, depending on how the applicator is made.

[0213] The container 3 has, in the example considered, a threaded neck 4 and the applicator 2 has a closing cap 5 arranged to attach to the neck 4 in order to close the container 3 in a leak-proof manner when not in use, the closing cap 5 also constituting a gripping member for the applicator 2.

[0214] Container 3 can still be made in another way.

[0215] The container 3 may include, as illustrated, a wringing device 6, for example snapped into collar 4.

[0216] The applicator 2 has a rod 7 with longitudinal axis Y, which connects at its upper end to the closing cap 5 and, at its lower end, to an application member 10, shown very schematically in [Fig.1], and which can be any one of those illustrated in the other figures or their variants.

[0217] The wringing member 6 can be of any type, and in the example considered comprises a lip arranged to wring the rod 7 and the application member 10 when The applicator 2 is removed from the container 3. The lip defines a wringing orifice 6a with a diameter adapted to that of the rod 7.

[0218] The wringing element 6 can be made of elastomer.

[0219] The spin-drying orifice 6a may be circular in shape, possibly with slots. The diameter d of the spin orifice 6a is for example between 2.5 and 8mm.

[0220] The wringing member 6 may optionally have undulations, allowing the wringing orifice 6a to widen more easily when the application member 10 passes through it.

[0221] The spin-drying unit can still be adjusted, if necessary.

[0222] In the illustrated example, the rod 7 has a circular cross-section, but this does not depart from the scope of the present invention if the rod 7 has a different cross-section, as the cap 5 can then be attached to the container 3 by a means other than screwing, if necessary. The wringing member 6 is adapted to the shape of the rod 7 and, where applicable, to that of the application member 10.

[0223] Preferably and as in the example illustrated in [Fig. 1], the longitudinal axis Y of the rod 7 is straight and coincides with the longitudinal axis of the container 3 when the applicator 2 is in place on it, but we do not depart from the scope of the present invention when the rod 7 is not straight, forming for example a bend.

[0224] The rod 7 may, where appropriate, include an annular constriction on its portion which is positioned opposite the lip of the wringing element 6, so as not to mechanically stress the latter excessively during storage.

[0225] The rod 7 to which the application member 10 is attached may be rigid or at least partially, in particular entirely, flexible, in particular in the vicinity of the application member 10.

[0226] The attachment of the application member 10 to the rod 7 can be done by any means and in particular by force mounting, snap-fitting, gluing, welding, stapling or crimping, in a corresponding housing 7a provided at the end of the rod 7. Alternatively, the application member 10 is made in one piece by molding of material with at least part of the rod 7.

[0227] In the following description, some application elements are intended more specifically for applying eyelash or eyebrow makeup and have raised features such as small bumps. Other embodiments are more specifically intended for applying a composition to the skin or lips and do not have any bumps. These application elements without bumps are preferably unflocked, but alternatively are covered with flocking fibers on at least part of their surface. Some application elements are shown without the bumps intended to cover them, for the sake of clarity.

[0228] Figures 2 to 10 partially represent an example of an application member 10 with longitudinal axis X, made by injection molding of at least one thermoplastic material, comprising an end piece 11 for fixing to the rod 7, intended to be received in the housing 7a of the latter.

[0229] The tip 11 extends towards the distal end of the application member 10 by means of a support part 12, forming a shoulder 13.

[0230] The application member 10 has a distal part 15 connected to the support part 12 by four branches 30a, 30b, 30c and 30d, of an arched shape convex outwards. The branches 30a and 30b are diametrically opposed and form with the distal part 15 a first loop extending along a plane P2, and the branches 30c and 30d likewise form a second loop along a plane P2' making an angle with the first, for example of 90° as can be seen in [Fig.3].

[0231] The application member 10 also includes, in this example, a cage 20 formed by four branches 20a, 20b, 20c and 20d, branches 20a and 20b forming a first loop extending along a plane PI and branches 20c and 20d a second loop extending along a plane PI', planes PI and PI' being for example arranged at 90° to each other, and plane PI making for example an angle of 45° with plane P2.

[0232] The branches are joined in 22, at the distal end of the cage 20, at a distance from the distal part 15, as can be seen in particular in [Fig.5].

[0233] The application member 10 may include two internal loops 80 and 84, each extending in the plane P2, with loop 84 connecting to the support part 12 and loop 80 to the distal part 15, as can be seen in particular in figures 4 and 8.

[0234] The two loops 84 and 80 are connected at their vertices by a bridge of material 81 which extends along the longitudinal axis X.

[0235] The branches 20a to 20d of the cage 20 each have a wavy shape, with two end portions 427 and 428 concave towards the X axis and an intermediate portion 429 convex towards the X axis, giving the cage 20 in side view a general peanut shape.

[0236] Portions 427 and 428 can be rounded, as illustrated, with a constant or variable radius of curvature. The intermediate portion 429 can be rounded, as illustrated, with a constant or variable radius of curvature.

[0237] The trough of the concave portion 429 is located at a distance Rlmin from the X-axis, and the vertices of portions 427 and 428 can be located at a distance from the X-axis greater than Rlmin. In the illustrated example, the vertices of portions 427 and 428 are located at the same distance Rlmax from the X-axis.

[0238] The branches 30a to 30b may have an outwardly arched shape, with a constant or variable radius of curvature, and a vertex when the branch is observed in a direction perpendicular to the X axis, located at a distance R2max greater than or equal to Rlmax.

[0239] For example, as shown in Figures 4 and 5, we have R2max>Rlmax>R>Rlmin or R2max>Rlmax>Rlmin>R, where R denotes the radius of the largest circle inscribed in the spin orifice. R is, for example, between 1.25 and 4 mm

[0240] The major radius plane R3max of the envelope surface defined by the free ends of the pins is, for example, defined by the free ends of the pins located on the vertices of the convex portions 427 or 428 of the branches 20a to 20d or at the summit of the branches 30a to 30d. By way of illustration, a pin 61 is shown in dashed lines in [Fig. 5] located on the convex portion 428 of one of the branches of the cage 20 and whose free end is located at a distance R3max from the X axis.

[0241] The free end of the pins located in the hollow of the concave portion 429 is preferably located at a distance greater than or equal to Rlmax.

[0242] The application member of figures 2 to 10 is provided with pins (only one of them is shown schematically on [Fig.5]) on branches 30a to 30d, on branches 20a to 20d, and possibly also on the distal part 15 and / or the support part 12.

[0243] The hollow formed by the portions 429 can allow for longer, more flexible spikes on them, and allows for the accumulation of more composition at their level.

[0244] The fact that the wavy branches 20a to 20d alternate around the X axis with the branches 30a to 30d, as can be seen in [Fig.3] in particular, allows for an alternation on the application organ of relatively uncharged areas (formed by the branches 30a to 30d) and more charged areas (defined by the hollow portions of the branches 20a to 20d), which allows both the charging and the separation of the cilia.

[0245] The convex portions 427 are less loaded than the concave portions 429, which makes it possible to compensate for the decrease in the diameter of the application organ by approaching the distal part, and to limit the load on the application organ, which makes it possible to retain a capacity for combing and separating eyelashes.

[0246] The application member 10 shown in figures 11 and 12 comprises an inner cage 20 formed of a first pair of branches 20a and 20b, extending along a plane PI and a second pair of branches 20c and 20d extending along a plane PI' which in this example is perpendicular to the plane PI, the branches 20a to 20d being joined at their distal end 22.

[0247] The application member comprises an outer cage 30 formed of a first pair of arms 30a and 30b, extending along a plane P2, and a second pair of arms 30c and 30d extending along a plane P2' which in this example perpendicular to plane P2, branches 30a to 30d being joined at their distal end 32, which coincides with the distal end of the application organ.

[0248] The planes PI and P2 make an angle of 45° with each other in the example considered.

[0249] The axial dimension of the outer cage 30 represents a very large part of the apparent length L of the application member, for example more than 80%, or even more than 90%.

[0250] The outer cage 30 has a general peanut shape, with a decrease in the distance to the X axis of branches 30a to 30d at about mid-length.

[0251] The branches 30a to 30d thus each present a succession, going from the support part 12 towards the distal end of the application organ 10, of an outwardly convex portion 438, a concave portion 439 and a convex portion 437.

[0252] The inner cage 20 may also have a general peanut shape, with a decrease in the distance to the X axis of branches 20a to 20d at about mid-length.

[0253] The branches 20a to 20d thus each present a succession, going from the support part 12 towards the distal end of the application organ 10, of an outwardly convex portion 428, a concave portion 429 and a convex portion 427.

[0254] This results in a stronger loading of the median region of the application member defined by the concave portions 429 and 439 at the crossing of the wringing member.

[0255] The loop formed by branches 20a and 20b crosses planes P2 and P2', and the same is true of the loop formed by branches 20c and 20d.

[0256] Figure 13 shows an example of the implantation of pins 61 on cages 20 and 30. The pins 61 are, for example, arranged in the form of radially oriented pins in a single row per branch, the pins 61 located near the support part 12 being longer, as are those located near the distal end of cages 20 or 30. The pins located in the hollow of the concave portions 427 and 437 can also be longer than those located at the top of the convex portions 428, 438, 427 and 437.

[0257] The variant of the application member 10 shown in Figures 14 to 19 comprises inner cages 20 and outer cages 30 as in the example of Figures 11 and 12.

[0258] The outer cage 30 has a general peanut shape, with a decrease in the distance to the X axis of branches 30a to 30d at about mid-length.

[0259] The branches 30a to 30d thus each present a succession, going from the support part 12 towards the distal end of the application organ 10, of an outwardly convex portion 438, a concave portion 439 and a convex portion 437.

[0260] The inner cage 20 may also have a general peanut shape as well, with a decrease in the distance to the X axis of branches 20a to 20d at about mid-length.

[0261] The branches 20a to 20d thus each present a succession, going from the support part 12 towards the distal end of the application organ 10, of an outwardly convex portion 428, a concave portion 429 and a convex portion 427.

[0262] The inner cage 20 has a larger outer diameter close to that of the outer cage 30, as can be seen in [Fig. 15].

[0263] The inner cage 20 includes bridges 100a to lOOd connecting the distal end 22 of the cage 20 to respective mid-zones 27a to 27d of the branches 20a to 20d, as well as bridges 101a to lOld connecting the support part 12 to the mid-zones 27a to 27d.

[0264] These various bridges tend to stiffen the inner cage 20, which can thus stretch the wringing member further, which contributes to wringing the application member more vigorously as it passes through the wringing member.

[0265] The application member of figures 14 to 19 has pins 61 (only one of them has been shown for illustration purposes in [Fig. 17] in dotted lines) on the cages 20 and 30, for example with an implantation similar to that of [Fig. 13].

[0266] Figures 20 to 27 show another variant with inner cage 20 and outer cage 30 which differs from that described with reference to Figures 11 and 12 by the presence of four stops 110 each connecting a branch of the inner cage 20 and an adjacent branch of the outer cage 30.

[0267] Each stop 110 has in cross-section a base 111 of general triangular shape, as seen in [Fig.26] in particular, this base 111 being connected at its longitudinal ends to the corresponding branches by radial uprights 112.

[0268] The length N of each stop 110 is for example between *4 and / 2 of the apparent length L of the application member 10.

[0269] The radial dimension of the uprights 112 is chosen such that the apex 113 of the base 111 is relatively close to the X-axis, so that when the arms of the cages 20 and 30 are pressed towards the center during the passage of the wringing element, the stops 110 bear against each other by their apex 113, which prevents the inward deformation of the arms. This results in a more thorough wringing of the application element as it passes through the wringing element.

[0270] We see on [Fig.26] in particular that the branches of the cages 20 or 30 can present in section a general triangular shape, with two straight segments 31a and 31b which diverge outwards, starting from the same vertex, and joined opposite this vertex by a rounded 31c.

[0271] We also see that two opposite branches can have parallel segments 31a in section, and the same for segments 31b.

[0272] The application member of figures 20 to 27 has pins (not shown) on cages 20 and 30, for example with an implantation similar to that of [Fig. 13].

[0273] The embodiment shown in Figures 28 and 29 differs from the previous one in that the arms of the outer cage 30 and inner cage 20 are interrupted between the uprights 112, with only the bases 111 of the stops connecting the remaining portions of the arms. These bases 111 thus form U-shaped notches with the adjacent portions of the arms, which constitute outwardly concave portions.

[0274] The branches 30a to 30d thus present a succession, going from the supporting part towards the distal end 32 of the cage 30, of an outwardly convex portion 438, a U-shaped concave portion 439 and a convex portion 437.

[0275] Similarly, branches 20a to 20d have a succession, going from the supporting part towards the distal end 22 of the cage 20, of an outwardly convex portion 428, a U-shaped concave portion 429 and a convex portion 427.

[0276] The narrowing of the section formed by the bases 111 allows for greater flexibility in the head of the application member 10.

[0277] The application member of Figures 28 and 29 has pins (not shown except those of [Fig.29] as detailed below) on cages 20 and 30.

[0278] The presence of the notches constituting the concave portions 429 and 439 allows longer and more flexible pins to be accommodated at their level, and provides a composition reserve at their base.

[0279] By way of illustration, radial pins 61 located at the top of portion 427 and in the bottom of portion 439 are shown in dashed lines in [Fig. 29]. The free ends of these pins can be located at respective distances R4 and R5 from the X-axis. R4 and R5 can be equal, or R4 > R5, or R4 <R5 en fonction de la forme de la surface enveloppe définie par les extrémités libres des picots, que l’on recherche, par exemple une forme « ballon » ou « cacahouète ».

[0280] The embodiment shown in Figures 30 to 34 differs from that shown in Figures 14 to 19 by the presence of reliefs 61 having a different shape from that of the generally truncated conical spikes illustrated in [Fig.13], namely a tooth-like shape, on each of the branches of the inner cage 20 and outer cage 30. These reliefs, like the spikes, allow the application of the composition to eyelashes and / or eyebrows and the combing of these.

[0281] Figures 35 to 41 partially represent a variant of an application member with an outer cage 30 and an inner cage 20, the branches of which each have a general twisted shape around the longitudinal axis X of the application member 10.

[0282] The branches 30a to 30d of the outer cage 30 can connect substantially perpendicularly to each other, when observed in projection in a plane perpendicular to the X axis, at the level of the distal end 32, as seen in particular in [Fig.36].

[0283] The same applies to the branches 20a to 20d of the inner cage 20 at the end 20, the branches 20a to 20d being angularly offset by 45° with those of the outer cage 30.

[0284] The branches 30a to 30d join the end 32 by being oriented along a cone with axis X, as do the branches 20a to 20d. All the branches connect to the support part 12 by being oriented forwards and outwards.

[0285] Each branch has a change in angular orientation around the X axis between its ends by which it connects to the support part 12 and to the other branches of the same cage of approximately 45° for example, in the same direction of rotation for all branches.

[0286] The branches 30a to 30d have undulations with a hollow 439 substantially at mid-length, bordered by bumps 437 and 438 on each side, giving the envelope of the application member 10 a generally peanut-shaped profile.

[0287] The arms 20a to 20d also have a wavy profile, with a hollow 429 substantially at mid-length, and bumps 427 and 428 on each side

[0288] We can see in [Fig.36] in particular that each loop formed by a pair of opposite branches of the inner cage, for example branches 20a and 20b or branches 20c and 20d, passes through the loops formed by the opposite branches of the outer cage 30, for example branches 30a and 30b or branches 30c and 30d.

[0289] The application member of figures 35 to 41 has pins (not shown) on cages 20 and 30, arranged for example in a similar manner to those in the example of [Fig.13].

[0290] The application member 10 shown in Figures 42 to 47 comprises an outer cage 30 and an inner cage 20, these defining a generally teardrop-shaped envelope surface with a maximum radius rmax located at a distance J from the shoulder 13, as illustrated in [Fig. 45]. For example, we have a ratio J / L, where Lest is the length of the application member measured from the shoulder 13, between 1 / 8 and 1 / 3, and rmax <D, D étant le plus grand diamètre de la partie de support 12 (qui correspond aussi sensiblement au diamètre de la tige) ce qui confère à l’organe d’application une forme relativement effilée.

[0291] The distal end 32 of the outer cage 30 may have a rounded shape, as seen in [Fig.44], for example substantially semi-circular in side view, which may allow the tip of the application organ to be used to apply the composition precisely and comfortably.

[0292] The branches 30a to 30d of the outer cage 30 can be straight over most of their length, as seen in [Fig.47], with for example an angle d between the axis of the straight portion and the X axis between 1 and 15°.

[0293] The arms 20a and 20b of the inner cage 20 extend along a plane PI and the arms 20c and 20d along a plane PI', and may have a slight inward curve approximately at mid-length, as can be seen in [Fig. 45]. This allows for a slight reduction in wringing in this area, thus providing product reserves at this point. Each of the arms 20a to 20d therefore presents a succession, from the support portion 12 to the distal end 22 of the cage 20, of an outwardly convex portion 428, a slightly concave portion 429, and a convex portion 427.

[0294] The planes PI and PI's are perpendicular to each other in this example. The same is true of the planes P2 and P2' along which hips 30a and 30b extend respectively on the one hand, and 30c and 30d on the other.

[0295] We see in [Fig.45] in particular that each loop formed by a pair of opposite branches of the inner cage, for example branches 20a and 20b or branches 20c and 20d, crosses the planes P2 and P2' of the loops formed by the opposite branches of the outer cage 30, for example branches 30a and 30b or branches 30c and 30d.

[0296] The application member of figures 42 to 47 has pins (not shown) on cages 20 and 30, with an implantation for example similar to that of the example in [Fig. 13],

[0297] The application element 10 partially shown (without the pins) in figures 48 to 53 is intended for application on eyelashes and / or eyebrows.

[0298] It comprises an outer cage 30, comprising four branches 30a to 30d, and an inner cage 20, comprising four branches 20a to 20d.

[0299] Branches 30a to 30d each have a wavy shape, as do branches 20a to 20d.

[0300] Thus, branches 20a to 20d present a succession, going from the supporting part towards the distal end 22 of the cage 20, of an outwardly convex portion 428, a concave portion 429 and a convex portion 427.

[0301] Similarly, branches 30a to 30d have a succession, going from the supporting part towards the distal end 32 of the cage 30, of an outwardly convex portion 438, a concave portion 439 and a convex portion 437.

[0302] The branches 30a to 30d meet at one end 32 and connect at the opposite end to the support part 12. The branches 20a to 20d meet at one end 22, located recessed from the end 32, and connect at the opposite end to the part support 12, respectively at the same angular positions, measured around the X axis, as branches 30a to 30d, as can be seen in [Fig.53] in particular.

[0303] Branches 30a to 30d and 20a to 20d are fitted with pins (not shown).

[0304] Figures 54 to 62 show an example of an application member 10 with axis longitudinal X, produced for example by injection molding of at least one thermoplastic material, comprising like the other examples described above an end piece 11 for fixing to the rod 7, intended to be received in the housing 7a of the latter.

[0305] The tip 11 extends towards the distal end of the application member 10 by means of a part 12, centered on the axis X, forming a shoulder 13.

[0306] Part 12 serves as a support for a first structure 30 having an armature in the form of a cage, composed of four branches 30a to 30d two by two diametrically opposed with respect to the longitudinal axis X of the application member.

[0307] The opposite branches 30a and 30b extend along a plane P2, containing the X axis.

[0308] The opposing branches 30c and 30d extend along a plane P2', perpendicular to the plan P2, as illustrated in [Fig.2].

[0309] The branches 30a to 30d join at an end 32 which is preferably centered on the X axis.

[0310] As can be seen in particular in [Fig.54], the branches 30a to 30d of the first structure 30 have an undulating shape with a proximal portion 438 convex outwards, an intermediate portion 439 concave inwards, and a distal portion 437 convex outwards, giving the cage a peanut shape in side view.

[0311] The branches 20a to 20d of the second structure 20 also have an undulating shape, with a proximal portion 428 convex outwards, an intermediate portion 429 concave outwards, and a distal portion 427 convex outwards, as seen in particular in [Fig.57].

[0312] The opposite branches 20a and 20b extend along a PI plane, containing the X axis.

[0313] The opposing branches 20c and 20d extend along a plane PI', perpendicular to the plan PI, as illustrated in [Fig.55].

[0314] Planes PI and P2 are offset by 45 degrees from each other, allowing branches 20a to 20d of the second structure 20 to extend between branches 30a to 30d of the first structure 30, as illustrated in [Fig.55].

[0315] The distal end 22 of the second structure 20 is set back along the X axis relative to the distal end 32 of the first structure 30, providing a free space which allows increased deformation and mobility of both structures 20 and 30 during application.

[0316] The opposite branches 20a and 20b of the second structure 20 form with the support part 12 a loop which carries a membrane 27 all around its inner perimeter.

[0317] The opposite branches 20c and 20d also form with the support part 12 a loop which carries a membrane 28 all around its inner perimeter.

[0318] The membranes 27 and 28 are perpendicular to each other, meeting on the X axis. They increase the capacity of the application member 10 to capture the composition. The thickness e2 of the membranes 27 and 28 is less than that ei of the branches 20a to 20d or 30a to 30d, with a ratio ei / e2 greater than or equal to 2, ideally 3 or 4. The small thickness of the membranes 27 and 28 gives them flexibility and suppleness, allowing the application member 10 to deform easily when passing through the wringing member 6.

[0319] The branches 20a to 20d and 30a to 30d each have a generally triangular cross-section, facilitating the demolding of the application member. This cross-section is formed by two substantially straight segments 301, converging towards the X axis, joined by a rounded 302 convex outwards.

[0320] The application organ of figures 54 to 62 has pins (not shown) or other reliefs for the application of the cosmetic composition to the eyelashes and / or eyebrows, implanted in various configurations, for example with a row of pins on each of the branches of structures 20 and 30, as in the example of [Fig.13].

[0321] The application member of Figures 63 to 71 differs from that of Figures 54 to 62 by the presence of two membranes 37 and 38 carried by the structure 30.

[0322] Membrane 37 occupies the space inside the loop formed by branches 30a and 30b, and membrane 38 that formed by branches 30c and 30d.

[0323] Membranes 37 and 38 are flat and perpendicular.

[0324] The thickness of membranes 37 and 38 is preferably, as illustrated, the same as that e2 of membranes 27 and 28.

[0325] All membranes 27, 28, 37 and 38 intersect along the X axis, as seen in [Fig.71], the set of membranes forming in cross-section, in a plane perpendicular to the X axis, an eight-rayed star.

[0326] The presence of the membranes facilitates the production of the application member by injection molding when each parting line is chosen at mid-thickness of a corresponding membrane. It also allows for a larger surface area for capturing the composition, without unduly stiffening the application member 10, due to their thinness.

[0327] The application organ of figures 63 to 71 has pins (not shown) for applying the cosmetic composition to the eyelashes and / or eyebrows, implanted in various configurations, for example with a row on each of the branches of structures 20 and 30, as in the example of [Fig.13].

[0328] The application elements 10, which have just been described with reference to Figures 2 to 71, are intended to be mounted on the end of an applicator rod. One does not exit of the framework of the present invention when the application member 10 is arranged to be supplied with composition from a reservoir on which it is permanently fixed.

[0329] Such a provision may be suitable when the composition is to be applied to the skin or lips.

[0330] In this case, the application member 10 is made with at least one composition supply channel, communicating with the reservoir. The nozzle 11 is fixed in a sealed manner in an opening communicating with the reservoir (not shown).

[0331] By way of example, figures 72 to 76 show an application device of this type, intended for application to the skin or lips.

[0332] In this example, the application member 10 comprises an inner cage 20 and an outer cage 30, each formed of four branches.

[0333] The application member 10 has a symmetry with respect to a median plane M which coincides with the cutting plane of [Fig.76].

[0334] The outer cage 30, viewed from the side, has a curvature that offsets its head. The branches 30a and 30b each have two straight portions joined by a bend 37, as can be seen in [Fig. 74]. The same is true of the branch 30d, as seen in [Fig. 76]. The branches of the inner cage 20 meet at its distal end 22, forming a cross in the front view, and the same is true of those of the outer cage 30, the two crosses being angularly offset by 45° in the front view.

[0335] The branches 20a and 20d are further away from the median plane M than are the opposite branches 20c and 20b, located on the side towards which the head of the application member 10 is eccentric, as can be seen in [Fig.73].

[0336] It can be seen in this figure in particular that each of the loops formed by opposite branches of the inner cage 20 passes through the loops formed by opposite branches of the outer cage 30.

[0337] The support part 12 may have, as illustrated, a generally frustoconical projection 373, centered on the X axis. Such a projection allows a capillary retention of composition to be formed at the rear of the application member.

[0338] The support part is traversed by a supply channel 371 in composition.

[0339] The supply channel 371 can receive composition from a device distribution device to which the applicator is associated, upstream of it and allowing to supply this channel with composition, such as a dispensing pen equipped with a composition dispensing mechanism, a compressible wall container, or other.

[0340] The channel 371 can open at the distal end of the support part 12, as illustrated.

[0341] The branches 20a and 20d of the cage 20 can each have a wavy shape, with a succession, from the support part 12 towards the distal end, of a convex portion 428, a concave portion 429 and a convex portion 427.

[0342] The application element 10 of figures 77 to 82 is intended for the application of the composition to the skin or lips.

[0343] It has a support part 12 having for example a shape of revolution around the longitudinal axis X, and a generally biconical lateral surface, with a proximal portion 12j adjacent to the tip 11 and diverging towards the distal end of the application member 10, and a convergent distal portion 12k.

[0344] The application member 10 comprises a first structure having a loop 30 extending along a median plane of symmetry M, formed by two branches 30a and 30b, visible in particular on [Fig.79], which meet at the end 32 of the loop 30 and connect at the other end to the portion 12k of the support part 12.

[0345] The first structure also includes loops 240 and 250 located on either side of a median plane of symmetry containing the X axis and perpendicular to the plane M.

[0346] The loop 240 has branches 240a and 240b which connect to the distal portion 12j of the support part 12 and join at the apex 242 of the loop. The same is true of the branches 250a and 250b of the loop 250, which join at the apex 252 thereof.

[0347] The application member 10 comprises a structure 20 in the form of a cage with four branches 220a, 220b, 220c and 220d connecting at one end to the portion 12k of the support part 12. The branches 220a and 220d form a loop on one side of the median plane of symmetry M, as can be seen in [Fig. 79]. The same is true of the branches 220b and 220c, on the other side of this plane M. Each of these loops is joined at its apex 222 to the other loop by an arch 221 having a concave shape towards the distal end of the application member 10, as can be seen in particular in [Fig. 79].

[0348] Thus, the diametrically opposed branches 220a and 220b form with the arch 221 a loop which crosses the plane of the loop 30, and the same is true of branches 220c and 220d.

[0349] The vertices 222 are free on the distal side.

[0350] The branches of the different structures 20, 30, 240 and 250 are arranged, for example angularly at 30° to each other for branches 220a, 240a, 30a, 240b and 220c, as seen in [Fig.79]. The same applies to branches 220b, 250b, 30b, 250a and 220d.

[0351] The branches 220d and 220a are arranged at 60° to each other around the X axis. The same is true of the branches 220c and 220b.

[0352] Such an arrangement of the branches allows us to benefit from an application surface all around the X axis.

[0353] The presence of the arch 221 tends to stiffen the loops formed by branches 220a and 220d on one side, and 220b and 220c on the other.

[0354] The branches 240a, 240b, 250a and 250b each have a wavy shape, as seen in particular in Figures 80 and 81, with, from the supporting part towards the distal end, for each of the branches 240a and 240b, a succession of a convex portion 448, a concave portion 449 and a convex portion 447, and similarly for each of the branches 250a and 250b a succession of a convex portion 458, a concave portion 459 and a convex portion 457.

[0355] Each of the branches 220a to 220d can also have a wavy shape, with, starting from the support part 12, a succession of a convex part 428, a concave part 429 and a convex part 427.

[0356] Of course, the invention is not limited to the examples just described.

[0357] In particular, the cross-sectional shape of the branches can be modified to facilitate manufacturing by injection molding. In particular, the branches can be given a substantially triangular shape as illustrated in [Fig. 71].

[0358] When produced by injection molding, the application member can be made in one piece by single injection, double injection or multi injection.

[0359] The expression "comprising one" should be understood as synonymous with "comprising at least one", unless otherwise specified.
