Description

[0001] Description

[0002] Title: Cosmetic applicator

[0003] Technical field

[0004] The present invention relates to applicators for applying a cosmetic, makeup or care, product to human keratin materials, notably the skin, the lips or keratin fibres such as the eyelashes and / or eyebrows, and to packaging and application devices comprising such applicators.

[0005] The invention relates more particularly to applicators comprising an applicator member made at least partially, better still completely, of plastics material, notably of at least one thermoplastic material by injection moulding.

[0006] The invention relates equally well to packaging and application devices of the “dipin” type, that is to say comprising an applicator and a reservoir in which the applicator is dipped in order to be loaded with composition, and those of the “flow-through” type, in which the applicator member is supplied with composition by a device to which it is secured during application, such as a dispensing pen provided with a composition dispensing mechanism, a container with a compressible wall, or the like.

[0007] Prior art

[0008] The applicators of the “dip-in” type used for making up the eyelashes or eyebrows usually comprise an applicator member mounted at the end of a stem, the latter being connected, at the other end, to a gripping member which also acts as a closure cap for closing the container containing the product.

[0009] The applicator member is conventionally loaded with product by being dipped into the container, which is provided with a wiper which has a lip for wiping the stem as it is withdrawn from the container and which generally defines an orifice of substantially circular section, the diameter of which is adapted to that of the stem.

[0010] The behaviour of the applicator member as it passes through the wiper depends on numerous factors such as the shape and nature of the lip of the wiper, and its dimensions, the geometry of the applicator member and the choice of the material(s) of which it is made.

[0011] Excessive wiping of the applicator member is likely to make it difficult to withdraw the latter from the container and causes the applicator member to be insufficiently loaded, obliging the user to frequently dip the applicator back into the container and potentially hindering the achievement of certain makeup effects. By contrast, insufficient wiping leaves excess product on the applicator member, which is difficult to distribute on the eyelashes and can result in the presence of clumps of product on the eyelashes, which are thus poorly separated.

[0012] Furthermore, the applicator member generally carries application elements constituted of spikes, the arrangement of which has an influence on the behaviour of the applicator as it is withdrawn from the container and on the resulting load.

[0013] Spikes that are very pliable will easily deform on passing through the wiper, thus making withdrawal easier, but their pliability means that it will be more difficult for them to comb the eyelashes suitably during application and to smooth the product over the surface thereof. In addition, the wiper will tend to leave less product on the applicator member.

[0014] On the other hand, more rigid spikes will tend to deform less when the applicator member passes through, resulting in greater loading of the applicator member with product and a better ability to comb and separate the eyelashes. However, they can make it more difficult to pass through the wiper and can bring about a loss of sensory impression during application.

[0015] The design of the applicator thus usually results from a compromise that has to be made between various requirements that are sometimes contradictory as regards the quantity of product that is left on the applicator member for makeup application, the desired behaviour on withdrawing the applicator member and the capacity for separating the eyelashes.

[0016] Conventionally, the spikes are carried by a central core of the applicator member. However, applicator members have been developed in which the spikes are carried by flexible arms.

[0017] Application FR3039382 describes an applicator comprising an elongate stem carrying an applicator member extending along a longitudinal axis. This applicator member comprises a core having one or more through-openings. Arms are connected at one end to the core and meet through said opening. In exemplary embodiments, the arms form several successive loops which are connected to one another at the opening or openings of the core. In another exemplary embodiment, the applicator member comprises a single loop connected at its ends to a support portion adjacent to the stem. The apex of the loop is located in the opening, bearing axially against an adjustment pin sliding longitudinally in a distal portion of the core. Thus, by depressing the adjustment pin more or less, it is possible to deform the loop and to modify the properties of the applicator.

[0018] Application FR2993151 describes an applicator member intended for making up eyelashes, having a core having bulging portions extending around cavities.

[0019] Application EP2654490 discloses applicator members comprising arms in the form of outwardly convex arches disposed around a central core.

[0020] Application WO2023 / 233044 describes an applicator member comprising a plurality of arms having a twist shape and connected to one another at their distal end.

[0021] Application US2021 / 0186183A1 describes an applicator member comprising a core connected at one of its ends to a support part carried by a fastening endpiece in an applicator stem. The core comprises a first portion that extends towards the front and a second portion that forms a return, the free end of which is in the vicinity of the support part. This return carries arches through which the first portion of the core passes.

[0022] Such an applicator member has a relatively complex structure, not suitable for manufacturing by injection-moulding thermoplastic material.

[0023] Patent US6655390 describes an applicator for making up eyelashes comprising a perforated support carrying teeth, the teeth being connected either directly to the support or to arches carried by the support.

[0024] Moreover, makeup of 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.

[0025] It is common to flock the applicator member so as to capture the composition and to be able to spread it more easily. However, the flocking operation is relatively complex and involves the use of adhesives, which do not always offer the mechanical strength required under certain conditions of use.

[0026] Patent EPl 726235B1 describes a flocked applicator member having several arms.

[0027] Application FR2722381 describes a nail varnish applicator comprising an applicator member formed by a flexible flocked loop.

[0028] Furthermore, it may prove useful to make the application more gentle by allowing a certain degree of mobility of the application surface relative to the longitudinal axis of the stem. Thus, patent US9033604 has proposed an applicator comprising, between the stem and an applicator member constituted of a mascara brush with a twisted core, an attached flexible part. The presence of this flexible part complicates the mounting of the applicator member.

[0029] It is also known, notably from US9277800 and US8096306, to provide the envelope surface of an applicator member provided with spikes with a shape passing through a minimum section in an intermediate zone, by adjusting the length of the spikes and / or the section of the core carrying the spikes. The spikes located in the zone of smaller section of the envelope surface tend to be less strongly wiped and more loaded with composition. However, having spikes of shorter length can make engagement in the eyelashes less effective. Moreover, the core generally does not have a large diameter, making it difficult to vary the section of the envelope surface simply by adjusting the dimension of the core.

[0030] Lastly, patent US8210763 discloses hybrid applicator members comprising a body made of elastomeric material in which extends a core made of a more rigid plastics material, which may be a pin moulded integrally with the stem to which the applicator member is fastened. The core extends over the major part of the length of the body of the applicator member.

[0031] US 7,918,619 discloses an applicator for applying a composition to the skin or lips, comprising a loop of generally triangular contour in top view, formed by two flocked arms having a first thickness, extending along a plane and defining an inner space in which a membrane having a second thickness smaller than the first extends, this membrane being parallel to said plane.

[0032] EP2836096 discloses an applicator member comprising at least four members defining between them at least three apertures.

[0033] An applicator member comprising arms supporting a membrane is described in EP 1726235.

[0034] Disclosure of the invention

[0035] There is a need to further improve cosmetic applicators and notably to remedy all or some of the drawbacks encountered in the prior art.

[0036] There is notably a benefit in having an applicator member which has satisfactory performance properties, which, when the applicator is used with a container equipped with a wiper, promotes the replenishment of the product during a cycle of withdrawing the applicator from and reinserting it into the container and the mechanical properties of which can be modified relatively easily during the design thereof, in order to adapt to the rheology of the product and to the desired makeup effect.

[0037] There is also a benefit in having an applicator member that is suitable for being manufactured by injection-moulding thermoplastic material, which is less expensive to implement than additive manufacturing.

[0038] There is also a need to benefit from an applicator suitable for the application of a composition to the skin or lips which is comfortable to use and makes it possible to avoid, if desired, the presence of flocking while retaining a sufficient capacity for capturing the composition.

[0039] Summary of the invention

[0040] The invention meets all or some of these needs by proposing an applicator comprising: an applicator member extending along a longitudinal axis, comprising: at least one support part, at least one first structure comprising at least two flexible arms extending over at least part of their length at a distance from the longitudinal axis and connected at one end to the support part, at least one second structure comprising at least one arm, this second structure extending at least partially between the two arms of the first structure, at least one of the arms of the first and second structures carrying a membrane of smaller thickness than that of the arm.

[0041] Such a membrane makes it possible to increase the capacity for retaining the composition by capillary action for the applicator member, without unduly affecting its flexibility, due to the reduced thickness of the membrane.

[0042] The membrane may have a constant or non-constant thickness; the thickness of the membrane is taken, in the case where it is not constant, as being the average thickness of the membrane. The arm may have a constant or non-constant thickness; the thickness of the arm is taken, in the case where it is not constant, as being the average thickness of the arm along the portion where it is in contact with the arm.

[0043] Preferably, the applicator member is produced by injection moulding and said membrane extends along a parting line of the mould. “Parting line” should be understood to mean the interface between two mould parts which, when the mould is closed, at least partially define a cavity of the mould used for moulding the material. This parting line may be a surface that is planar or of non-planar shape.

[0044] The fact that the membrane extends along a parting line of the applicator member facilitates the manufacture of the injection mould used to produce the applicator member. Specifically, in the absence of a membrane, any failure to close of the mould at the parting line of an arm leads to a risk of plastics material leakage and of creating a burr on the arm. Here, the presence of the membrane makes the tightness of the closure of the mould at the arm less critical, since a flow can be provided for the formation of the membrane.

[0045] Said arm may be of thickness ei and the membrane is of thickness e2, with ei / e2>2, better still ei / e2>3, even better still ei / e2>4.

[0046] Said membrane may be of thickness less than or equal to 0.5 mm, better still 0.4 mm, even better still be of thickness between 0.1 and 0.3 mm, notably between 0.15 and 0.25 mm.

[0047] At least one of the first and second structures may comprise two arms connected to the support part and forming a loop, these two arms carrying said membrane over at least part of their periphery.

[0048] Said membrane may occupy the entire inner space of said loop. In this case, the membrane may be connected at its periphery to the arms forming the loop and to the support part between the arms.

[0049] In a variant, said membrane occupies only part of the inner space of said loop. This can make it possible to provide one or more openings in the membrane, and this facilitates the circulation of the composition and can increase the flexibility of the applicator member. This can also create more capillary traps for the composition within the applicator member. The openings may have various shapes, be disposed in a regular or non-regular arrangement, in rows or otherwise. The openings may form a grid. The first and second structures may comprise arms whose longitudinal axes are non-coplanar. This gives the applicator a three-dimensional configuration, capable of storing the composition internally, while retaining the required flexibility. This can also make it possible to have a composition retention capacity that renders the presence of a flocking coating unnecessary. Thus, the applicator member may be non-flocked, facilitating its production and recycling.

[0050] The applicator member may comprise several membranes carried by respective arms or loops, these membranes extending in distinct respective planes. These respective planes may notably be secant, notably cross on the longitudinal axis of the applicator member.

[0051] At least two membranes may thus cross, notably cross along the longitudinal axis of the applicator member. This can make it possible to benefit from a certain degree of rigidity with respect to bending loads to which the applicator member is subjected during use, while retaining a capacity for radial deformation.

[0052] In exemplary embodiments, the first structure comprises a cage having at least three arms each connected at one end to the support part and the second structure comprises a cage having at least three arms each connected at one end to the support part, the second structure extending at least partially inside the first, said membrane being carried by at least one of the arms of said cages. Each cage may comprise four arms, and one of the cages may carry two membranes, notably two membranes that are perpendicular to one another.

[0053] The applicator member may notably comprise at least two membranes carried by at least one of said cages, notably comprise at least one membrane carried by each of said cages. Each cage may comprise four arms, and each cage two membranes, notably two membranes that are perpendicular to one another.

[0054] In other exemplary embodiments, the first structure comprises at least two loops that are at least partially superposed, the second structure comprising at least one through- arm which extends through at least one of said superposed loops. The second structure may notably comprise a loop extending along a first plane, and the second structure at least two superposed loops extending along planes parallel to a second plane perpendicular to the first.

[0055] The membrane may then be carried by said through-arm.

[0056] The membrane may also be carried by at least one of said superposed loops. In this case, the membrane may occupy the entirety of the inner space of the loop, or in a variant have an opening through which the through-arm extends. This can allow said through-arm to retain greater flexibility, since it then remains free with respect to the membrane.

[0057] The applicator member may also comprise a first membrane carried by one of said superposed loops, and a second membrane carried by the through-arm. These membranes may meet, for example along the longitudinal axis of the applicator member.

[0058] In general, the membrane may be perforated, notably comprise several openings. In the case of the above examples comprising at least two loops that are at least partially superposed and at least one through-arm, the membrane carried by the through-arm advantageously comprises openings, which may be in the form of openings of different contours, for example circular, or in the form of windows with parallel edges. The membrane carried by one of the superposed loops may also carry a perforated membrane.

[0059] As mentioned above, the membrane may occupy the entire space inside the loop that carries it, and notably extend between the two opposite arms of this loop, while also connecting to the support part. In exemplary embodiments, the membrane has a free radially inner edge over at least a portion of its length. The membrane may notably extend along a radial plane, towards the longitudinal axis of the applicator member.

[0060] In exemplary embodiments, the applicator member comprises several membranes oriented generally radially inwards, connected over a portion of their length to a central body of the applicator member. This central body may be passed through by a channel for conveying the composition.

[0061] In exemplary embodiments, the first structure comprises a loop carrying said membrane, the arms of which are connected at one end to the support part, one or more intermediate structures each comprising a loop whose arms are connected to the support part and meet at the apex of the loop, the second structure comprising arms which are each connected at one end to the support part and connected at the other end to one another by an arch, said membrane extending between the distal end of the loop of the first structure and the apex of the loops of the intermediate structures. The membrane thus connects the apex of these intermediate structures to the first structure, thus giving it greater rigidity.

[0062] Applicator member

[0063] The applicator member may be mounted at the end of a stem so as to be inserted into a container equipped with a wiper and be loaded with composition. In a variant, the applicator member is supplied directly by the container via a supply channel. In this case, the device does not comprise a wiper. This variant is rather reserved for an applicator member intended for application to the skin or lips, or hair.

[0064] The applicator member may comprise an endpiece for mounting in an applicator stem; this endpiece may have a circular cross section, of constant diameter or decreasing towards the proximal end of the applicator member. The endpiece may form with the support part a shoulder, the contour of which may be circular, having a diameter corresponding to the outer diameter of the stem of the applicator. This shoulder can come into abutment against the stem during the mounting of the applicator member.

[0065] The mounting endpiece may be solid.

[0066] The endpiece may also be hollow, notably in a variant in which the applicator member comprises a housing and the stem an extension passing through the endpiece and engaging in this housing, thus making it possible to act on the rigidity of the applicator member, as detailed below.

[0067] The endpiece may also be hollow and passed through by a central opening when the applicator member is intended to be fastened in the mouth of a container, so as to form a composition supply channel, as mentioned above.

[0068] The endpiece may also have a central opening in order to receive the core of a brush with a twisted core, when the applicator is hybrid, as detailed below.

[0069] The support part may have a length that may be less than one quarter of the length of the visible portion of the applicator member, that is to say in the presence of the aforementioned shoulder, the length extending between the distal end of the applicator member and this shoulder.

[0070] The support part may also be longer, notably in order to occupy the central space of the applicator member and to allow capillary traps to be formed with arms of the first and / or second structures disposed around them.

[0071] The support part may carry spikes, when the applicator is intended for application of a composition to keratin fibres such as the eyelashes. The spikes are, for example, disposed in rows located in the continuation of spikes carried by arms of the first and / or second structures.

[0072] The distal end of the applicator member may be defined by the first structure. In a variant, the distal end of the applicator member is defined by a distal part that extends between the distal end of the applicator member and the first structure.

[0073] Such a distal part may be solid, and of for example circular cross section, the distal part possibly being of a longitudinal axis that is coincident with the longitudinal axis of the support part and that of the endpiece.

[0074] The applicator member may be intended for application of the composition to a continuous surface, such as the skin or lips, or discontinuous surface, such as keratin fibres, notably the eyelashes and / or eyebrows.

[0075] In the case of application to a continuous surface, the applicator member is advantageously free of flocking. The pliability of the arms, their shape and their proximity can allow the composition to be sufficiently retained by surface tension so that such a flocking coating is not necessary. This simplifies the manufacture of the applicator, and improves its reliability insofar as it is not necessary to ensure the resistance of the adhesive used to bond the flocking with respect to the composition and the forces exerted during wiping or use.

[0076] In the case of use to apply a composition to keratin fibres, the applicator member may carry application elements such as spikes or other reliefs, which may be located on the whole or on only a portion of the applicator member. The expression “spike or other relief’ denotes any individualizable protuberance suitable for applying the composition to the eyelashes and / or eyebrows, notably capable of engaging between the eyelashes and / or eyebrows.

[0077] The aforementioned distal part may thus carry such application elements when the applicator is intended for application to keratin fibres such as the eyelashes.

[0078] These application elements may be disposed in the form of rows which are, for example, aligned with rows of spike application elements carried by arms of the first and / or second structures.

[0079] In the presence of a distal part, the first and second structures may act as an articulation allowing the distal part to easily change orientation relative to the axis of the support part, under the effect of a pressure exerted during application for example. By choosing the configuration of the arms of the first and second structures, notably by having a distribution of the arms about the longitudinal axis of the applicator member that is not uniform, it is possible to ensure that the deformability of the first and second structures is promoted about certain pivot axes, and this can improve the behaviour of the applicator during application of the composition by using certain zones of the applicator member. In a variant, the first structure provides the connection between the support and distal parts with at least three arms that are evenly distributed angularly about the longitudinal axis of the applicator member, thus ensuring uniform behaviour of the connection in all directions.

[0080] The first and second structures may comprise arms which are connected to the support part along a corresponding radial plane, forming an angle with the longitudinal axis of the applicator member, this angle ranging, for example, from 0 to 90°, preferably between 0 and 60°. Such a preferential orientation of the arms can facilitate passage through the wiper.

[0081] The first and / or second structures may have arms having in section a shape suitable for demoulding thereof in an injection moulding manufacturing method, notably arms which in section have rectilinear sides diverging outwards, joined by an outwardly convex rounded portion.

[0082] In order to define the application surface for the composition, the applicator may comprise only the applicator member, which may be in one piece. The application surface can thus be unflocked.

[0083] In a variant, the applicator is hybrid, and the applicator member serves as a support for another element, such as a brush with a twisted core. This can make it possible to make a compromise between the load and combing provided by the bristles of the brush and the load and combing provided by the spikes.

[0084] In this case, the loop(s) or cage(s) formed by the first and / or second structures may advantageously contribute to retaining the portion of the brush carrying the bristles, notably by extending between them.

[0085] The applicator member can be produced without the possibility of adjusting its configuration, unlike that described in the aforementioned application FR3039382, and notably without any element that can be fixed in one of two predefined positions.

[0086] First structure

[0087] The aforementioned first structure may be formed by a free loop, the two arms meeting at the distal end of the applicator member, the two ends of the arms opposite the apex of the loop being connected to the support part. This loop may extend in the axial direction, notably along a plane, which preferably contains a longitudinal axis of the support part.

[0088] The first structure may also comprise more than two arms, thus forming, for example, a cage, the arms being connected at one end to the support part and meeting one another at the opposite end, which may define the distal end of the applicator member.

[0089] The first structure may have an even number of arms greater than two, for example four or six, in diametrically opposite pairs, two opposite arms forming a loop preferably extending in a plane containing the longitudinal axis of the applicator member.

[0090] The first structure may exhibit axial symmetry with respect to the longitudinal axis of the applicator member, or only symmetry with respect to a median plane, or exhibit no symmetry whatsoever.

[0091] The first structure may have a length which corresponds to more or less half the visible length of the applicator member.

[0092] The first structure may define the distal end of the applicator member or may serve to connect the support part to a distal part of the applicator member, which distal part is, for example, solid or carries another application element such as a brush with a twisted core.

[0093] The distal part may thus comprise a solid or hollowed-out central body, of circular or non-circular section, centred on the longitudinal axis of an endpiece of the applicator member serving for fastening to the stem of the applicator. The largest diameter of the distal part corresponds, for example, substantially to that of the support part.

[0094] The length of this distal part may or may not exceed that of the first structure.

[0095] The distal part may have a rectilinear longitudinal axis aligned with that of the support part.

[0096] The first structure may comprise two diametrically opposite arms extending along a first plane, of which one is outwardly convex and the other is substantially parallel thereto, and two other arms extending along a second plane perpendicular to the first, these two other arms being symmetrical to one another with respect to a median plane.

[0097] The first structure may have arms having at least one undulation, notably several identical undulating arms, for example giving the first structure the general shape of a peanut.

[0098] The arms of the first structure may be connected to those of the second structure, notably in a median region of the applicator member; this connection is effected, for example, by means of connecting elements radially inside the arms. Such connecting elements may be arranged so as to come into abutment against one another when the arms are pressed radially inwards, as may be the case when passing through the wiper. This makes it possible to obtain a stronger scraping of the surface of the applicator member by the wiper.

[0099] The first structure may comprise arms which are twisted about the longitudinal axis of the applicator member, these arms being, in examples, joined to the distal end of the applicator member.

[0100] The first structure may comprise a cage comprising several arms defining an envelope surface whose diameter increases from the support part, passes through a maximum in the vicinity of the support part, and decreases up to the distal end of the applicator member. Such a cage can thus have a profile in the general shape of a “drop of water”.

[0101] When the first structure defines an outer cage, having several arms, these arms may be connected together at the distal end of the applicator member in the form of a cross or star, the arms being, for example, tangential to a plane perpendicular to the longitudinal axis of the applicator member; this makes it possible to define a relatively large application surface at the head of the applicator member, and this can be useful for applying a composition to the skin or lips.

[0102] In a variant, the arms are connected to one another at the distal end of the applicator member in the form of a cone converging towards the distal end; this makes it possible to have a thinner application tip at the distal end of the applicator member. This can be beneficial for drawing a line on the eyelids or the contour of the lips, for example.

[0103] The first structure may comprise several loops that are parallel to one another. In this case, the loops may be of decreasing length going outwards, at least on one side, and this can make it possible to define an application surface that is substantially bevelled or of dihedral shape. The presence of close loops makes it possible to define capillary traps between them, while having a capacity to store composition inside the loops.

[0104] With such a configuration of the first structure in particular, the support part may comprise a projection which extends parallel to the parallel loops, on one side thereof. This can make it possible to have a more rigid portion on the applicator member, and this can be useful to benefit, for example at the end, from a zone allowing the composition to be applied precisely. The loop of the second structure may then have its ends connected, one to the projection, and the other to a rear portion of the support part from which the parallel loops extend. In a variant, the first structure comprises several loops disposed symmetrically with respect to a plane of symmetry, parallel to which the loops extend; in this case in particular, at least one of the loops, notably the longest, may carry a membrane on its inner periphery, this membrane comprising an opening through which the loop of the second structure passes.

[0105] Such a membrane may be of thickness less than that of the strand of material constituting the loop to which it is connected, notably more than two times less, or even more than three or four times less, thus allowing the membrane to retain its pliability and to not unduly hinder the deformation of the loop.

[0106] The first structure may comprise a cage having an eccentric head, for example with two opposite angled arms, having proximal portions parallel to the longitudinal axis of the support part and distal portions forming an angle with the proximal portion and directed to one side, and two other arms extending along a median plane of symmetry for the applicator member, which are generally curved on the same side.

[0107] The first structure may comprise arms carrying a membrane, preferably on their inner periphery, this membrane having a free edge over at least a portion of its length. Such a membrane can facilitate the retention of the composition, and this can be useful notably when the composition has low viscosity.

[0108] Second structure

[0109] The second structure may be formed by a single loop, extending, for example, in a plane containing the longitudinal axis of the applicator member.

[0110] The second structure may have a single loop which passes through a cage constituted by the first structure or an intermediate cage which itself passes through a loop formed by the first structure. In this case, there is, for example, the loop forming the second structure which extends along a plane forming an angle of 45° with the plane along which the loop forming the first structure extends, and the intermediate cage comprises two loops which extend along planes which are perpendicular to one another and one of which is disposed at 45° to the plane of the loop forming the second structure.

[0111] The second structure may be formed by a single loop, the first structure as well, and the applicator member may comprise an intermediate loop passing through the loop forming the first structure, the loop forming the second structure passing through both the loop forming the intermediate structure and the loop forming the first structure. The second structure may comprise more than two arms, for example forming a cage, the arms being joined at one end, notably four arms, preferably in diametrically opposite pairs. The presence of a cage can give more mechanical strength to the arms and to the applicator member.

[0112] These four arms may form two loops that are joined at the distal end of the cage, extending along two respective planes that are perpendicular to one another.

[0113] The arms may each comprise at least one undulation, each loop formed by two opposite arms having, for example, the general shape of a peanut when observed facing its plane.

[0114] The second structure may comprise a loop having two arms forming in front view, when observed along the longitudinal axis of the applicator member, a V.

[0115] Such a shape is advantageously combined with a first structure having at least one arm in the form of an outwardly convex arch, the two arms of the loop of the second structure being located on each side of this arm in the form of an outwardly convex arch. This can make it possible to increase the spacing between the arms on one side of the applicator member and to have arms close together on the opposite side, and this can be useful for having different application properties with the same applicator member depending on the face used. The close-together arms can notably retain more composition between them, by capillary action, and thus have a greater loading action than the opposite side, where the arms are more distant and less capable of retaining the composition between them by capillary action.

[0116] When both the first structure and the second structure comprise cages having several arms joined at one end, the two cages are advantageously offset angularly with respect to one another about the longitudinal axis of the applicator member, by an angle equal to 360° / n, where n denotes the total number of arms. Preferably, each cage comprises the same number of arms, notably four arms.

[0117] In a variant, when both the first structure and the second structure comprise cages having several arms joined at one end, the cages are not angularly offset with respect to one another, the arms of the innermost cage each being located in the same plane as at least one arm of the outermost cage. The second structure may comprise a loop which is stiffened internally by a latticeshaped, notably diamond-shaped, structure that is connected simultaneously to a median zone of the opposite arms of the loop, to the apex of the latter and to the support part.

[0118] The second structure may comprise a cage whose arms define, in a median zone, an outwardly open notch. Such a notch may make it possible, when the applicator member carries spikes, to have, for example, longer spikes which are connected at their base to the bottom of the notch.

[0119] The second structure may comprise a cage whose arms are twisted about the longitudinal axis of the applicator member. Such a twisted shape can improve the management of the eyelashes, when the arms carry spikes.

[0120] The second structure may comprise a cage comprising several arms defining an envelope surface whose diameter increases from the support part, passes through a maximum in the vicinity of the support part, and decreases up to the distal end of the applicator member.

[0121] The second structure may be formed by a loop which is connected at its ends to a rear portion of the support part, this support part being for example of generally circular contour when observed along the longitudinal axis of the applicator member, and the other end is connected to a generally flattened projection of the support part. Such a shape of the second structure is advantageously combined with a first structure comprising loops that are generally parallel to one another and preferably parallel to the projection and preferably also stepped, as mentioned above.

[0122] The second structure may comprise a cage whose apex is eccentric with respect to the longitudinal axis of the applicator member.

[0123] The second structure may comprise arms bordered on their inner periphery by a thin radial membrane, this membrane having a free edge over at least part of its length. The presence of such a membrane can improve the capacity of the applicator member to retain the composition by capillary action, and facilitate manufacture, as detailed below.

[0124] The second structure, just like the first, may carry spikes or other reliefs when the applicator member is intended for application of a composition to the eyelashes and / or eyebrows.

[0125] Arms

[0126] The first and second structures comprise flexible arms that may form loops or cages. 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 planar surface, for example a planar surface perpendicular to the longitudinal axis of the applicator member.

[0127] A cage may be formed of at least three arms, preferably an even number of arms, for example 4 or 6.

[0128] The arms may have a circular or other cross section, and preferably the arms have a cross section that is suitable for manufacturing the applicator member by inj ection moulding.

[0129] The arms may notably 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 joining of two substantially rectilinear segments starting from an apex, diverging outwards, and of a rounded portion joining said segments.

[0130] Such a shape in section can facilitate withdrawal from the mould used for the injection moulding, and thus limit the risk of the applicator member being damaged when it is withdrawn during demoulding.

[0131] Preferably, two opposite arms of the same structure have, on the same side, in the same section plane perpendicular to the longitudinal axis of the applicator member, segments which are parallel to one another. This can facilitate the release of the shells used for moulding the applicator member.

[0132] An arm may occupy in section between 0.01 and 20 mm2, better still between 0.2 and 5 mm2. Its largest transverse dimension (that is to say the diameter in the case of an arm of circular section) may range from 0.1 to 4 mm for example. The deployed length of an arm, between its end for connecting to the support part and its opposite end, for example the distal end of the loop or cage to which this arm belongs, ranges for example from 3 to 60 mm.

[0133] The applicator member may be inscribed in section in a circle having a diameter ranging from 4 to 12 mm for an applicator intended for application to eyelashes or eyebrows, and a circle ranging from 4 to 17 mm for an applicator intended for application to the lips.

[0134] The arms may carry, over at least a portion of their inner periphery, a membrane of lesser thickness, for example with a ratio ei / e2, where ei denotes the thickness of the arm and e2denotes the thickness of the membrane, greater than 2, better still than 3, even better still than 4. Such a membrane can facilitate the production of the applicator member by injection moulding, by extending along the parting line, as mentioned above. Independently of this advantage, the membrane can also increase the surface area available to retain the composition, without unduly affecting the flexibility of the arms.

[0135] The term “loop” denotes an arm or succession of arms defining, with one or more other parts of the applicator member, a closed contour surrounding an inner space distinct from the arm or arms. The loop may extend along the same plane which contains the longitudinal axes of the arms. The loop may also not extend in a single plane. The loop may or may not be symmetrical with respect to a median plane. The loop may have the ends of its constituent arm or arms located on the support part at the same axial position along the longitudinal axis of the applicator member. The arm or arms constituting the loop may extend angularly around a point located in the aforementioned inner space, over an angle of at least 120°, better still at least 180°.

[0136] In exemplary embodiments, the first structure comprises a loop formed by two opposite arms, said loop carrying a membrane which occupies only part of the inner opening of the loop. The applicator member comprises an additional structure having an internal loop formed by two opposite arms, said internal loop being connected, at its distal end, to the membrane, notably at a proximal edge thereof. The second structure may be a cage comprising four arms whose planes are offset angularly, notably by 45°, with respect to a plane along which the loop of the first structure extends. The internal loop may extend along a plane perpendicular to the plane of the loop of the first structure. The membrane may provide a mechanical connection between the three structures at the front of the applicator member. The membrane may not extend between the arms of the additional structure at a distance from the location where the arms of the internal loop meet. The arms of the first and second structures and of the additional structure may each have an undulating shape with, going towards the distal end, a convex portion, a concave portion and then an outwardly convex portion. In a variant, the first and second structures and the additional structure may each have the general shape of a drop of water, the arms preferably having in this case a rectilinear portion occupying a major part of their length and inclined relative to the longitudinal axis of the applicator member. The applicator member may comprise application elements in the form of spikes placed in rows on each of the arms of the different structures.

[0137] Manufacture of the applicator member In examples of implementation of the invention, the applicator member can be produced by injection-moulding thermoplastic material as a single piece, making it possible to reduce the manufacturing cost compared with an additive manufacturing technique. This can also make it easier to use plastics materials that are recyclable or obtained from recycled materials. The applicator member may be moulded from a thermoplastic material chosen, for example, from thermoplastic elastomers, SEBS, TPE, notably Hytrel® (thermoplastic elastomer copolyester), TPV, PE, notably LDPE or HDPE, or the like.

[0138] The applicator member may notably be produced from a relatively pliable material, and the presence of membrane(s) within the applicator member, when it (they) connect(s) the first and second structures or one of the first and second structures with one or more intermediate structures, makes it possible to increase the rigidity of the applicator member or to use, with comparable rigidity, a more pliable thermoplastic material, making it possible to further improve the comfort of application.

[0139] The applicator member is preferably produced by injection-moulding thermoplastic material, but it may be produced in a different way when its shape does not allow it, then being produced in that case for example by an additive manufacturing technique.

[0216] Figure 1 shows an example of a packaging and application device 1 produced in accordance with the invention, comprising an applicator 2 and an associated container 3 containing a product P to be applied to human keratin fibres, for example the eyelashes or eyebrows, or in a variant the skin or lips, depending on the way that the applicator is produced.

[0217] The container 3 comprises, in the example in question, a threaded neck 4 and the applicator 2 comprises a closure cap 5 designed to be fastened on the neck 4 so as to close the container 3 in a sealed manner when it is not in use, the closure cap 5 also constituting a gripping member for the applicator 2.

[0218] The container 3 may also be produced in some other way.

[0219] The container 3 may comprise, as illustrated, a wiping member 6, for example snap-fastened in the neck 4.

[0220] The applicator 2 comprises a stem 7 of longitudinal axis Y, which is connected at its upper end to the closure cap 5 and, at its lower end, to an applicator member 10, shown in highly schematic form in Figure 1, and which may be any of those illustrated in the other figures or variants thereof.

[0221] The wiping member 6 may be any wiping member and comprises, in the example in question, a lip designed to wipe the stem 7 and the applicator member 10 when the applicator 2 is withdrawn from the container 3. The lip defines a wiping orifice 6a having a diameter adapted to that of the stem 7.

[0222] The wiping member 6 may be made of elastomer.

[0223] The wiping orifice 6a may be of circular shape, possibly with slits. The diameter d of the wiping orifice 6a is, for example, between 2.5 and 8 mm.

[0224] The wiping member 6 may optionally have undulations, allowing the wiping orifice 6a to widen more easily when the applicator member 10 passes through.

[0225] The wiping member may also be adjustable, if appropriate.

[0226] In the example illustrated, the stem 7 has a circular cross section, but it would not constitute a departure from the scope of the present invention if the stem 7 had a different section, it then being possible to fasten the cap 5 to the container 3 in some way other than by screwing, if necessary. The wiping member 6 is adapted to the shape of the stem 7 and to that of the applicator member 10, if appropriate. Preferably, and as in the example illustrated in Figure 1, the longitudinal axis Y of the stem 7 is rectilinear and coincident with the longitudinal axis of the container 3 when the applicator 2 is in place thereon, but it would not constitute a departure from the scope of the present invention if the stem 7 were not rectilinear, forming for example a bend.

[0227] If need be, the stem 7 may have an annular narrowing at its portion that is positioned opposite the lip of the wiping member 6, so as not to mechanically stress the latter unduly during storage.

[0228] The stem 7, to which the applicator member 10 is fastened, may be rigid or at least partially, and notably completely, flexible, notably in the vicinity of the applicator member 10.

[0229] The applicator member 10 may be fastened to the stem 7 by any means, and notably by force-fitting, snap-fastening, adhesive bonding, welding, stapling or crimping, in a corresponding housing 7a provided at the end of the stem 7. In a variant, the applicator member 10 is made as a single piece by moulding material with at least part of the stem 7.

[0230] Figures 2 to 10 show an example of an applicator member 10 of longitudinal axis X, produced for example by injection-moulding at least one thermoplastic material, comprising an endpiece 11 for fastening to the stem 7, intended to be received in the housing 7a of the latter.

[0231] The endpiece 11 is extended towards the distal end of the applicator member 10 by a part 12 centred on the axis X, forming a shoulder 13.

[0232] The part 12 serves as a support for a first structure 30 having a reinforcement in the form of a cage, composed of four arms 30a to 30d in diametrically opposite pairs with respect to the longitudinal axis X of the applicator member.

[0233] The opposite arms 30a and 30b extend along a plane P2 containing the axis X.

[0234] The opposite arms 30c and 30d extend along a plane P2’ perpendicular to the plane P2, as illustrated in Figure 2.

[0235] The arms 30a to 30d meet at an end 32 which is preferably centred on the axis X.

[0236] As can be seen in Figure 8 in particular, the arms 30a to 30d of the first structure 30 have an undulating shape with an outwardly convex proximal portion 34, an inwardly concave intermediate portion 35, and an outwardly convex distal portion 36, giving the cage a peanut shape in side view. The arms 20a to 20d of the second structure 20 also have an undulating shape, with an outwardly convex proximal portion 24, an outwardly concave intermediate portion 25, and an outwardly convex distal portion 26, as can be seen notably in Figure 8.

[0237] The opposite arms 20a and 20b extend along a plane Pl containing the axis X.

[0238] The opposite arms 20c and 20d extend along a plane Pl’ perpendicular to the plane Pl, as illustrated in Figure 3.

[0239] The planes Pl and P2 are offset by 45 degrees with respect to one another, allowing the arms 20a to 20d of the second structure 20 to extend between the arms 30a to 30d of the first structure 30, as illustrated in Figure 3.

[0240] The distal end 22 of the second structure 20 is set back along the axis X with respect to the distal end 32 of the first structure 30, providing a free space which allows deformation and increased mobility of the two structures 20 and 30 during application.

[0241] The opposite arms 20a and 20b of the second structure 20 form with the support part 12 a loop which carries a membrane 27 over its entire inner periphery.

[0242] The opposite arms 20c and 20d also form with the support part 12 a loop which carries a membrane 28 over its entire inner periphery.

[0243] The membranes 27 and 28 are perpendicular to one another, meeting on the axis X. They increase the capacity of the applicator member 10 to capture the composition. The thickness e2of the membranes 27 and 28 (measured perpendicularly to their plane) is less than that ei (measured in a direction parallel to e2) of the arms 20a to 20d or 30a to 30d, with a ratio ei / e2greater than or equal to 2, ideally 3 or 4. The small thickness of the membranes 27 and 28 gives them flexibility and pliability, allowing the applicator member 10 to deform easily when passing through the wiping member 6.

[0244] The arms 20a to 20d and 30a to 30d each have a generally triangular section, facilitating demoulding of the applicator member. This section is formed by two substantially rectilinear segments 301 converging towards the axis X and connected by an outwardly convex rounded portion 302.

[0245] The applicator member in Figures 2 to 10 may carry spikes (not shown) or other reliefs for application of the cosmetic composition to the eyelashes and / or eyebrows, which are placed in various configurations, for example with a row of spikes on each of the arms of the structures 20 and 30. The applicator member in Figures 11 to 19 differs from that in Figures 2 to 10 by the presence of two membranes 37 and 38 carried by the structure 30.

[0246] The membrane 37 occupies the space inside the loop formed by the arms 30a and 30b, and the membrane 38 the one formed by the arms 30c and 30d.

[0247] The membranes 37 and 38 are planar and perpendicular.

[0248] The thickness of the membranes 37 and 38 is preferably, as illustrated, the same as that e2of the membranes 27 and 28.

[0249] All the membranes 27, 28, 37 and 38 intersect along the axis X, as can be seen in Figure 19, all the membranes forming in cross section, in a plane perpendicular to the axis X, an eight-pointed star.

[0250] The presence of the membranes facilitates the production of the application member by injection moulding when each of the parting lines is chosen to be half-way through the thickness of a corresponding membrane. It also makes it possible to have a larger surface area for capturing the composition, without thereby unduly stiffening the applicator member 10, due to their small thickness.

[0251] The applicator member in Figures 11 to 19 may carry spikes (not shown) for application of the cosmetic composition to the eyelashes and / or eyebrows, which are placed in various configurations, for example with a row on each of the arms of the structures 20 and 30.

[0252] The variant in Figures 20 to 24 comprises a central loop 1030 extending along a plane P2, and upper 1050 and lower 1050’ loops extending along respective planes that are parallel to the plane P2 and to the longitudinal axis of the applicator member 10.

[0253] The loop 1030 carries a thin membrane 1035 having a thickness e2less than that ei of the strand forming the loop, as can be seen in Figure 17.

[0254] The applicator member 10 also comprises a loop 1020 extending along a plane Pl perpendicular to the plane P2.

[0255] The loop 1020 comprises two opposite arcuate arms 1020a and 1020b which meet via the membrane 1035.

[0256] The loop 1020 carries a thin membrane 1025, the thickness of which is for example the same as that of the membrane 1035. The ratio of the thickness of the strand of material forming the loop 1020 to that of the membrane 1025 is for example the same as for the loop 1030 and the membrane 1035. The presence of the membranes 1025 and 1035 makes it possible to increase the surface area for the capture of the composition by the applicator member 10. Their fineness makes it possible not to unduly stiffen the loops, which thus retain a certain degree of pliability, and can thus deform when passing through the wiping member or when applying the composition to the skin or lips.

[0257] The applicator member 10 in Figures 25 to 29 differs from that in Figures 20 to 24 by the presence of openings 1026 on the membrane 1025.

[0258] The arrangement of the openings 1026 may be varied, these being disposed, for example, in two superposed rows extending along the longitudinal axis of the applicator member 10, as can be seen in Figure 29.

[0259] The openings 1026 may be of any shape, for example being of circular shape as illustrated.

[0260] The presence of the openings 1026 makes it possible to further improve the retention of the composition on the applicator member 10 by capillary action, and can increase the flexibility of the membrane 1025.

[0261] The applicator member 10 in Figures 30 to 34 differs from that in Figures 20 to 24 by the presence of openings both in the membrane 1025 carried by the loop 1020 and in the membrane 1035 carried by the loop 1030.

[0262] These openings are, for the membrane 1025, as can be seen notably in Figure 34, in the form of windows 1027 with parallel edges 1027a, extending between the opposite arms 1020a and 1020b of the loop 1020, these edges 1027a being perpendicular to the longitudinal axis X of the applicator member 10.

[0263] These openings are also, for the membrane 1035, in the form of windows 1037 with parallel edges 1037a, extending between the opposite arms 1030a and 1030b of the loop 1030, these edges 1037a being perpendicular to the axis X.

[0264] The windows 1027 and 1037 may have the same width, as illustrated, and occupy the same axial position along the axis X.

[0265] The windows 1027 delimit strips 1029 which extend between the arms 1020a and 1020b, and the windows 1037 likewise delimit strips 1039 which extend between the arms 1030a and 1030b.

[0266] The strips 1029 and 1039 are perpendicular to one another in the example illustrated, and form inside the loops 1020 and 1030 a very open and also flexible structure, capable of retaining the composition by capillary action and allowing good circulation of the composition through the applicator member when loading the applicator member with composition and passing it through the wiping member.

[0267] The number of strips 1029 present inside the loop 1020 is for example between 1 and 20, better still 2 and 10, even better still 2 and 5, for example 3 or 4 as illustrated in Figure 32. The width of a strip 1029 or 1039 ranges for example from 0.3 mm to 15 mm, better still from 1 mm to 10 mm, even better still from 1 to 5 mm.

[0268] At least one window 1037 can be located in front of the loop 1020, as can be seen in Figure 30, and the arms 1020a and 1020b of the loop 1020 can be connected to the strip 1039 adjacent to this window 1037.

[0269] The applicator member in Figures 35 to 39 differs from that in Figures 20 to 24 by the absence of the membrane 1025 carried by the loop 1020 and by the presence of an opening 1206 in the membrane 1035, this opening being passed through by the loop 1020.

[0270] The loop 1020 extends along a plane Pl which is also a plane of symmetry for the applicator member 10, and the loop 1030 extends along a plane P2 perpendicular to the plane Pl.

[0271] The loops 1050 and 1050’ extend along respective planes P6 and P6’ that are parallel to the plane P2 and located on either side thereof, the plane P2 also being a plane of symmetry for the applicator member 10.

[0272] The loop 1030 is defined by a bead of material of thickness ei measured perpendicularly to the plane P2, the flexible membrane 1035 being of thickness e2.

[0273] The opening 1206 may widen towards the front, as can be seen in Figure 30, in order to allow axial mobility of the loop 1020 during application, until the latter comes into abutment against the rear end 1207 of the opening 1206.

[0274] The opening 1206 also allows a certain degree of lateral mobility of the loop 1020 when the latter is away from the end 1207.

[0275] The applicator members 10 which have just been described with reference to Figures 1 to 39 are designed to be mounted at the end of an applicator stem. It would not constitute a departure from the scope of the present invention if the applicator member 10 were designed to be supplied with composition from a reservoir to which it is permanently fastened. Such an arrangement may be suitable when the composition is to be applied to the skin or lips.

[0276] In this case, the applicator member 10 is produced with at least one composition supply channel communicating with the reservoir. The endpiece 11 is sealingly fastened in an opening communicating with the reservoir (not shown).

[0277] By way of example, Figures 41 to 48 show an applicator member of this type, intended for application to the skin or lips, which has a composition supply channel 371 formed at the centre of a central body 373 extending the support part 12 towards the front.

[0278] The applicator member 10 comprises an inner cage 20 and an outer cage 30 that are each formed of four arms.

[0279] The applicator member 10 exhibits symmetry with respect to a median plane M which is coincident with the section plane of Figure 43.

[0280] The outer cage 30 has, in side view, a curvature which makes the head eccentric, the arms 30a and 30b each having two rectilinear portions joined by a bend 37, as can be seen in Figure 42. The same is true of the arm 30d. The arms of the inner cage 20 meet at the distal end 22 thereof, forming a cross in front view, and the same is true of the arms of the outer cage 30, the two crosses being offset angularly in front view by 45°.

[0281] The arms 20a and 20c are further away from the median plane M than are the opposite arms 20b and 20d located on the side towards which the head of the applicator member 10 is eccentric, as can be seen in Figure 42.

[0282] The arms are closer together on the eccentric side, allowing for a larger contact surface with the zone to be treated.

[0283] The supply channel 371 can receive the composition coming from a dispensing device with which the applicator is associated, and making it possible to supply this channel with composition, such as a dispensing pen provided with a composition dispensing mechanism, a container with a compressible wall, or the like.

[0284] The applicator member 10 comprises additional reliefs for capturing the composition, for example a set of radial fins 375 extending along the body 373, membranes 378 extending along the arms of the inner cage 20 and membranes 377 extending along the arms of the outer cage 30.

[0285] The membranes 378 are directed radially and form openings 379 with the central body 373. The membranes 377 are also directed radially towards the central body 373 and form openings 381 therewith.

[0286] The membranes 377 meet the central body 373 from a certain distance from the support part 12, going towards the latter, as can be seen in Figures 46 to 48.

[0287] It can be seen in Figures 44 and 48 that the channel 371 opens out laterally on the opposite side from the eccentricity of the head of the applicator member 10 (that is to say upwards in Figure 48) via an opening 372. The latter is preferably, as illustrated, closer to the distal end of the applicator member 10 than to the shoulder 13 at the base of the support part 12.

[0288] The fins 375 extend radially outwards between an arm of the inner cage 20 and an arm of the outer cage 30, substantially in a plane bisecting the membranes 377 and 378, as can be seen notably in Figure 46.

[0289] Together with the membranes 377 and 378, the fins 375 make it possible to constitute capillary traps which retain the composition, and thus tend to make the distribution of the composition within the applicator member more uniform.

[0290] The membranes 377 and 378 are of reduced thickness e2compared with that ei of the strands of material constituting the adjoining arms 20a to 20d or 30a to 30d, and do not unduly disrupt the pliability of the applicator when used to apply the composition to the skin or lips. For example, ei / e2>2, better still ei / e2>3, even better still ei / e2>4.

[0291] The openings 379 and 381 ensure the circulation of the composition over almost the entire periphery thereof.

[0292] Each loop formed by two diametrically opposite arms of the inner cage 20 passes through the plane of the loops formed by two diametrically opposite arms of the outer cage 30.

[0293] An example of the placement of application elements such as spikes on an applicator member repeating the configuration of the one in the example of Figures 20 to 24 will now be described, with reference to Figures 49 to 53.

[0294] It thus comprises a loop 1020 which extends along a plane Pl which is also a plane of symmetry, and a loop 1030 which extends along a plane P2 perpendicular to the plane Pl.

[0295] The loop 1020 carries spikes 68, the longitudinal axes of which are contained in the plane Pl. The loop 1030 carries spikes 65, the longitudinal axes of which are contained in the plane P2.

[0296] Two other loops 1050 and 1050’ extend along respective planes P6 and P6’ that are parallel to the plane P2, the plane P2 being a plane of symmetry for the applicator member 10.

[0297] The loop 1050 carries spikes 64, each extending obliquely forming an angle q with the plane P6, the angle q being, for example, of the order of 45°.

[0298] The loop 1050’ carries spikes 66 also forming an angle q with the plane P6’.

[0299] The rows of spikes 68 provided on the opposite arms 1020a and 1020b of the loop 20 begin set back from the end 1022, in such a way that the ends of all the spikes 68 located on the arm 1020a protrude above the loop 1050, as can be seen in Figure 53.

[0300] The applicator member 10 in Figures 54 to 59 is intended for application of the composition to the skin or lips.

[0301] It has a support part 12 having, for example, a shape of revolution about the longitudinal axis X, and a generally biconical lateral surface, with a proximal portion 12j adjacent to the endpiece 11 and diverging towards the distal end of the applicator member 10, and a convergent distal part 12k.

[0302] The applicator member 10 comprises a first structure comprising a loop 30 extending along a median plane of symmetry M, formed by two arms 30a and 30b, visible in Figure 59 in particular, which join at the end 32 of the loop 30 and are connected at the other end to the portion 12k of the support part 12.

[0303] The loop 30 carries a membrane 321 at the concavity formed at its end 32, and this membrane extends as far as the apexes 242, 252 of intermediate structures 240 and 250, each comprising two arms which are connected at one end to the portion 12k of the support part 12 and meet at the opposite end at their apex.

[0304] The applicator member also comprises a structure 20 having the form of a cage with four arms 220a, 220b, 220c and 220d which are connected at one end to the portion 12k of the support part 12. The arms 220a and 220d form a loop on one side of the median plane of symmetry M, as can be seen in Figure 55. The same is true of the arms 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 applicator member 10, as can be seen notably in Figure 58. Thus, the diametrically opposite arms 220a and 220b form with the arch 221 a loop which passes through the plane of the loop 30, and the same is true of the arms 220c and 220d.

[0305] The apexes 222 are free on the distal side.

[0306] The arms of the different structures 20, 30, 240 and 250 are, for example, disposed angularly at 30° from one another as regards the arms 220a, 240a, 30a, 240b and 220c, as can be seen in Figure 55. The same is true of the arms 220b, 250b, 30b, 250a and 220d.

[0307] The arms 220d and 220a are disposed at 60° from one another about the axis X. The same is true of the arms 220c and 220b.

[0308] Such an arrangement of the arms makes it possible to benefit from an application surface all around the axis X.

[0309] The presence of the arch 221 tends to stiffen the loops formed by the arms 220a and 220d on one side, and 220b and 220c on the other.

[0310] The membrane 321 makes it possible both to have an additional surface for capturing the composition and to stiffen the intermediate structures 240 and 250 by securing them, via the membrane 321, to the loop 30.

[0311] Conversely, the loop 30 is stiffened by the intermediate structures 240 and 250 via the membrane 321.

[0312] In the example illustrated, the membrane 321 does not intersect the entire section of the intermediate structures 240 and 250 at their respective apexes 242 and 252, but in a variant the membrane 321 intersects the entire section.

[0313] The membrane 321 preferably has a thickness e2that is small with respect to ebwith values of the ratio ei / e2as defined above.

[0314] The strands of material constituting the arms of the different structures may or may not have the same section.

[0315] The arms may be of circular section, the arms 220a to 220d being, for example, of smaller diameter than the arms 240a, 240b, 250a and 250b, which is itself smaller than that of the arms 30a and 30b.

[0316] The diameter of the arms 220a to 220d is, for example, 0.75 mm, that of the arms 240a, 240b, 250a and 250b is, for example, 0.8 mm and that of the arms 30a and 30b is, for example, 0.85 mm. The width of the applicator member 10 measured perpendicularly to the median plane M is, for example, between 5 and 6 mm, notably approximately 5.5 mm, and that measured parallel to the median plane between the radially outermost sides of the arms 30a and 30b is preferably greater, and is, for example, between 6.5 and 7.5 mm, notably approximately 7 mm.

[0317] In the example illustrated, there is, for example, a visible length L of the applicator member of between 10 and 20 mm, notably between 13 and 17 mm, for example approximately 14 mm.

[0318] The axial dimension of the support part 12 is, for example, between 2 and 3 mm, notably of the order of 2.5 mm.

[0319] The diameter of the support part 12 at its base is, for example, between 4 and 5 mm, for example approximately 4.5 mm. The largest diameter of the support part 12, at the junction between the portions 12j and 12k, is, for example, approximately 5.3 mm.

[0320] The thickness e2of the membrane 321 is, for example, 0.2 mm, and the thickness ei of the loop 30 is, for example, 0.8 mm as mentioned above.

[0321] The variant in Figures 60 to 64 differs from the example of Figures 54 to 59 by the presence of a central column 330 extending along the axis X, having a proximal portion 331 connecting the support part 12 and the arch 221 in its middle, and a distal portion 332 connecting the arch 221 to the membrane 321, as can be seen more particularly in Figure 64.

[0322] The portion 331 may have a conical shape whose section decreases towards the arch 221. The portion 332 may be of constant section, as illustrated.

[0323] The presence of the central column 330 makes it possible to further stiffen the applicator member 10, and to benefit from an additional surface for capturing the composition. It can also facilitate the flow of the thermoplastic material during the manufacture by injection moulding of the applicator member. Figures 65 to 70 show another example of an applicator member 10 of longitudinal axis X, produced by injection-moulding at least one thermoplastic material, comprising an endpiece 11 for fastening to the stem 7, intended to be received in the housing 7a of the latter.

[0324] The endpiece 11 is extended towards the distal end of the applicator member 10 by a part 12 centred on the axis X, forming a shoulder 13. The part 12 serves as a support for a first structure 30 in the form of a loop composed of two diametrically opposite arms 30a and 30b with respect to the longitudinal axis X of the applicator member.

[0325] The arms 30a and 30b extend along a plane P2 containing the axis X, as illustrated in Figure 70.

[0326] The arms 30a to 30d meet at an end 32 which is preferably centred on the axis X, and which may bear the trace of a sprue for injecting the thermoplastic material, as can be seen in Figure 66.

[0327] As can be seen in Figure 65 in particular, the arms 30a and 30b of the first structure 30 may have an undulating shape with an outwardly convex proximal portion 34, an outwardly concave intermediate portion 35, and an outwardly convex distal portion 36, giving the loop a peanut shape in side view (in a direction of observation perpendicular to the plane of the loop).

[0328] The applicator member 10 comprises a second structure 20 in the form of a cage comprising four arms 20a to 20d, each also having an undulating shape, with an outwardly convex proximal portion 24, an inwardly concave intermediate portion 25, and an outwardly convex distal portion 26, as can be seen notably in Figure 65.

[0329] The opposite arms 20a and 20b extend along a plane Pl containing the axis X, as illustrated in Figure 70. The opposite arms 20c and 20d extend along a plane Pl’ perpendicular to the plane Pl .

[0330] The planes Pl and P2 are offset by 45 degrees with respect to one another, allowing the arm 30a of the first structure 30 to extend between the arms 20a and 20d of the second structure 20, and the arm 30b to extend between the arms 20b and 20c, as illustrated in Figure 70.

[0331] The distal end 22 of the second structure 20 is located substantially at the same level on the axis X as the distal end 32 of the first structure 30.

[0332] The arms 30a and 30b carry a membrane 1120 over a part of their inner periphery from the distal end 32. The arms 20a to 20d meet through this membrane 1120, as can be seen in Figure 68. Thus, the loop formed by the opposite arms 20a, 20b passes through the loop formed by the arms 30a and 30b, passing from one side to the other of the plane of this loop, and the same is true of the loop formed by the arms 20c, 20d which also passes through the plane along which the loop formed by the arms 30a, 30b extends. The applicator member 10 comprises an additional structure 1100 in the form of a loop comprising two arms 1100a and 1100b which are connected at their proximal ends to the part 12 and meet at their distal ends at the proximal edge of the membrane 1120.

[0333] The arms 1100a and 1100b extend along a plane P3 perpendicular to the plane P2. Thus, the loop formed by these arms 1100a and 1100b passes not only perpendicularly through the plane along which the loop formed by the arms 30a and 30b extends, but also obliquely through the plane of the loop formed by the arms 20a and 20b and that of the loop formed by the arms 20c and 20d, as can be seen in Figure 67.

[0334] The arms 1100a and 1100b also each have an undulating shape, with a convex proximal portion 1104, a concave intermediate portion 1105 and an outwardly convex distal portion 1106.

[0335] The different orientations of the arms create a three-dimensional structure with crossed planes which allows the eyelashes to be engaged through 360°, and can facilitate the circulation of the composition between the different planes.

[0336] The membrane 1120 has a thickness e2that is small compared with that ei of the arms 30a and 30b, with a ratio ei / e2greater than or equal to 2, ideally 3 or 4. The small thickness of the membrane 1120 gives it flexibility and pliability.

[0337] The membrane 1120 participates in the mechanical cohesion of the applicator member, and connects the three structures 20, 30 and 1100 at the front. This can make it possible to stabilize the distal part of the applicator member, and this can be useful notably to avoid axial crushing when it is returned to the container, without having to resort to a harder material to produce the applicator member.

[0338] The applicator member 10 carries spikes 1110 for application of the cosmetic composition to the eyelashes and / or eyebrows, which are placed for example with a row on each of the arms of the structures 20, 30 and 1100, as illustrated.

[0339] Each row of spikes 1110 may comprise an alternation of spikes 1110a and 1110b as can be seen notably in Figure 65, each spike 1110a extending for example, as illustrated, on one side of a median plane for the arm, which may also be a parting line, having a planar face facing towards this median plane and an opposite, generally semi-frustoconical face, and each adjacent spike 1110b, substantially of the same shape, being located on the other side of the median plane, with its planar face also facing towards this median plane. The applicator member 10 shown in Figures 71 to 76 is also intended for application to the eyelashes and / or eyebrows, and differs from the preceding applicator member notably by the shape of the arms.

[0340] It is produced by injection-moulding at least one thermoplastic material, comprising an endpiece 11 for fastening to the stem 7.

[0341] The endpiece 11 is extended towards the distal end of the applicator member 10 by a part 12 centred on the axis X, forming a shoulder 13.

[0342] The part 12 serves as a support for a first structure 30 in the form of a loop composed of two diametrically opposite arms 30a and 30b with respect to the longitudinal axis X of the applicator member.

[0343] The arms 30a and 30b extend along a plane P2 containing the axis X, as illustrated in Figure 74.

[0344] The arms 30a to 30d meet at an end 32 which may correspond to the distal end of the applicator member, as illustrated.

[0345] As can be seen in Figure 76 in particular, the arms 30a and 30b may form a loop having substantially the shape of a drop of water (in a direction of observation perpendicular to the plane of the loop), which is relatively narrow, with a rounded distal end. The arms 30a and 30b may each have a rectilinear portion 39 of axis XB inclined with respect to the longitudinal axis X, extending over the major part of the arm.

[0346] The applicator member 10 comprises a second structure 20 in the form of a cage comprising four arms 20a to 20d, having the general shape of a drop of water, which is relatively narrow, each with a rectilinear portion 29 extending over the major part of their length.

[0347] The opposite arms 20a and 20b extend along a plane Pl containing the axis X, as illustrated in Figure 74. The opposite arms 20c and 20d extend along a plane Pl’ perpendicular to the plane Pl .

[0348] The planes Pl and P2 are offset by 45 degrees with respect to one another, allowing the arm 30a of the first structure 30 to extend between the arms 20a and 20d of the second structure 20, and the arm 30b to extend between the arms 20b and 20c.

[0349] The distal end 22 of the second structure 20 is located substantially at the same level on the axis X as the distal end 32 of the first structure 30. The arms 30a and 30b carry a membrane 1120 over a part of their inner periphery from the distal end 32. The arms 20a to 20d meet through this membrane 1120, as can be seen in Figure 75.

[0350] The applicator member 10 comprises an additional structure 1100 in the form of a loop comprising two arms 1100a and 1100b which are connected at their proximal ends to the part 12 and meet at their distal ends at the proximal edge of the membrane 1120.

[0351] The arms 1100a and 1100b extend along a plane P3 perpendicular to the plane P2.

[0352] The loop formed by the arms 1100a and 1100b also has the general shape of a drop of water, each of them having a rectilinear portion 1109 occupying a major part of their length and inclined relative to the axis X.

[0353] The shape of a drop of water can reduce the load peak when withdrawing the applicator member, during passage through the wiper.

[0354] Just like for the example of Figures 65 to 70, the membrane 1120 participates in the mechanical cohesion of the applicator member, and connects the three structures 20, 30 and 1100 at the front.

[0355] The applicator member 10 carries spikes 1110 for application of the cosmetic composition to the eyelashes and / or eyebrows, which are placed for example with a row on each of the arms of the structures 20, 30 and 1100, as illustrated.

[0356] Each row of spikes 1110 may comprise an alternation of spikes 1110a and 1110b as can be seen notably in Figure 72, each spike 1110a extending for example, as illustrated, on one side of a median plane for the arm, which may also be a parting line, having a planar face facing towards this median plane and an opposite, generally semi-frustoconical face, and each adjacent spike 1110b, substantially of the same shape, being located on the other side of the median plane, with its planar face also facing towards this median plane.

[0357] The applicator member 10 may comprise series of spikes 1110c which extend in the continuation of the spikes 1110 carried by the arms 1100a and 1100b, as can be seen in Figure 72 in particular. These spikes 1110c, for example four on each side, may be connected at their base to the membrane 1120 or to the distal end of the structure 20, and may have, like for the spikes 1110a and 1110b, a semi-frustoconical shape, with a planar face contained in the median plane of the arms 1100a and 1100b, and opposite faces located alternately on either side of this median plane. Of course, the invention is not limited to the examples that have just been described.

[0358] In particular, the sectional shape of the arms can be modified in order to facilitate manufacture by injection moulding. It is notably possible to provide the arms with a substantially triangular shape.

[0359] When it is produced by injection molding, the applicator member can be made in one piece by mono-injection, bi-inj ection or multi-injection.

[0360] In variants that are not illustrated, the applicator members described above without spikes may be provided with spikes, or any other application elements, or even any surface structuring.

[0361] The expression "comprising a" should be understood as being synonymous with "comprising at least one", unless otherwise specified.

Applicator according to any one of Claims 1 to 10, the first structure comprising a loop carrying said membrane, the arms of which are connected to the support part, one or more intermediate structures (240; 250) each comprising a loop whose arms are connected to the support part and meet at the apex (242; 252) of the loop, the second structure comprising arms (20a, 20b, 20c, 20d) which are connected at one end to the support part (12) and connected at the other end to one another by an arch (421), the membrane (321) extending between the distal end (32) of the loop (30) of the first structure and the apex (242; 252) of the loops of the intermediate structures.

23. Applicator according to any one of Claims 1 to 5, wherein the first structure (30) comprises a loop formed by two opposite arms (30a, 30b), said loop carrying a membrane (1120) which occupies only part of the inner opening of the loop, the applicator member comprises an additional structure (1100) having an internal loop formed by two opposite arms (1100a, 1100b), said internal loop being connected, at its distal end, to the membrane (1120), notably at a proximal edge thereof, the second structure (20) being a cage comprising four arms (20a, 20b, 20c, 20d) whose planes (Pl, Pl’) are offset angularly, notably by 45°, with respect to a plane (P2) along which the loop of the first structure (30) extends, the internal loop (1100a, 1100b) extending along a plane (P3) perpendicular to the plane (P2) of the loop (30).

24. Applicator according to Claim 23, the membrane (1120) providing a mechanical connection between the three structures (20, 30, 1100) at the front of the applicator member (10).

25. Applicator according to Claim 24, the membrane (1120) not extending between the arms (1100a, 1100b) of the additional structure (1100) at a distance from the location where said arms meet, so that the internal loop remains free over a major part of its opening.

26. Applicator according to any one of Claims 23 to 25, the arms (30a, 30b; 20a to 20d; 1100a, 1100b) each having an undulating shape with, going towards the distal end, a convex portion, a concave portion and then an outwardly convex portion.

27. Applicator according to any one of Claims 23 to 25, the structures (20, 30, 1100) each having the general shape of a drop of water, the arms comprising a rectilinear portion occupying a major part of their length and inclined relative to the longitudinal axis (X).

28. Applicator according to any one of Claims 23 to 27, the applicator member(10) comprising application elements in the form of spikes (1110) placed in rows on each of the arms of the different structures (30a, 30b; 20a to 20d; 1100a, 1100b).
