Description

Title of the invention: Device for conditioning and applying a cosmetic product to the lips. Technical field

[0001] The present invention relates to the application of a cosmetic product to the lips. Previous technique

[0002] To apply a cosmetic product to the lips, it is known to use a device comprising a container on which is mounted an applicator comprising an application member disposed at the end of a rod.

[0003] EP1080659, EP3241458 and EP3300624 describe such devices.

[0004] The container generally includes a wringing element to wipe the rod and prevent the presence of an excessive load of product on the application element.

[0005] It was also proposed in application FR 2 888 097 to make the wringing lip with undulations in order to allow it to deform more easily when passing the application element.

[0006] The realization of the application member for a given wringing member generally results from a compromise between a shape suitable for a thorough wringing of the application surface, in order to obtain a precise application, in particular to draw the contour of the lips, and the presence of at least one product reservoir giving autonomy to the applicator and preventing the user from having to dip it back into the container too often. Description of the invention

[0007] There is a need to further improve the devices for applying a cosmetic product to the lips in order to allow for a quick and precise application of the product, in a simple and comfortable way for the user. Summary of the invention

[0008] The present invention addresses this need by means of a device for conditioning and applying a cosmetic product to the lips, comprising:

[0009] - a container holding the product to be applied, equipped with a wringing device having a spin lip defining a spin orifice having a smaller transverse dimension;

[0010] - an applicator for applying the product, comprising:

[0011] o a rod extending along a longitudinal axis;

[0012] o an application member carried by the rod at one end thereof,

[0013] the application member having an application surface defining a main application face having a general shape curved around an axis of curvature substantially perpendicular to the longitudinal axis of the rod, the application member having a width, measured parallel to the axis of curvature, which is maximum or close to the maximum substantially at a proximal end of the main application face, this width being greater than said smallest transverse dimension of the wringing orifice, the cross-section of the application member having a non-circular contour, preferably substantially polygonal, at the level of the proximal end of the main application face.

[0014] Thanks to the shape of the application element, the latter will expand the wringing element unevenly early upon its extraction from the container, with maximum deformation of the wringing element occurring when the proximal end of the main application face belonging to the application element passes through the wringing orifice. This deformation of the wringing element, in combination with the non-circular, preferably substantially polygonal, contour section, allows a relatively large product load to accumulate on the main application face while maintaining the application element's ability to apply makeup precisely.

[0015] The product charge is advantageously sufficient to apply cosmetic product to at least one entire lip, lower or upper, after a single extraction from the container.

[0016] In addition, the generally curved shape of the main application face allows comfortable contact with the lips, and the application organ advantageously defines at the proximal end of the main application face an edge which tends by pressing on the lip to retain the product on the main application face when applying the product to the lower lip.

[0017] By "maximum or close to the maximum" it should be understood that the width is greater than or equal to 80% of the maximum width, better 90%.

[0018] By "substantially at a proximal end of the main application face" it should be understood to mean at the level of the proximal end or a distance from it corresponding to less than 20%, better to 10%, of the total length of the application organ excluding the stem.

[0019] By "substantially polygonal", it is meant that each side of the section deviates at most from a straight line joining the vertices of the polygon by less than 20%, better 10%, even better 5%, of the length of the side in question.

[0020] The contour of the cross-section of the application member at the proximal end of the main application face can generally be rectangular or generally square, with rounded corners, preferably generally rectangular.

[0021] The application member may have flanks inclined at an angle of less than 30°, preferably less than 20°, with a median plane of symmetry for the application member. The application member may, in particular, comprise two flanks meeting approximately at mid-thickness, the width of the application member being maximum at this junction. The parting line may be located at the junction of the flanks when the application member is produced by injection molding in a two-shell mold.

[0022] The cross-section of the application member can be substantially polygonal over at least 70%, better 80%, even better over at least 90%, or even over the entire length of the application member, measured along the longitudinal axis, outside the rod.

[0023] The proximal end of the main application face can be located at a non-zero distance from the stem, in particular between 0.5 mm and 5 mm. It is closer to the stem than to the distal end of the application member.

[0024] The proximal end of the main application face can be located at a distance from the stem of between 5% and 30% of the length of the application organ outside the stem.

[0025] The length Ho of the application member, outside the rod, measured along the longitudinal axis of the rod, can be between 8 and 30 mm.

[0026] The width W of the application member, measured parallel to the axis of curvature, can be between 5 mm and 10 mm, preferably between 6 and 8 mm.

[0027] The applicator stem may have a circular cross-section with a diameter between 4 mm and 10 mm, preferably between 6 and 8 mm.

[0028] The maximum width, measured parallel to the axis of curvature, of the application member may be strictly greater than the maximum thickness of the application member. The thickness of the application member may be greatest substantially at the proximal end of the main application face.

[0029] The width, measured parallel to the axis of curvature, of the application member can decrease as one approaches the distal end of the application member. This can allow for the definition of inclined facets at the end of the applicator, useful for drawing the contour of the lips, and can also facilitate the insertion of the applicator into the container, through the wringing member, by generating a progressive deformation of the wringing orifice.

[0030] The applicator can be symmetrical with respect to a longitudinal median plane, cutting the application member at mid-width.

[0031] The main application surface, located on the side of the concavity formed by the curvature of the application device, may have a radius of curvature, constant or variable, which is, for example, between 10 mm and 20 mm. Such a curvature can allow it to approximate the curvature, in a vertical cross-section, of the lower lip and / or the upper lip. This improves the comfort of applying the cosmetic composition.

[0032] The principal application face can be generated by a generatrix that is a straight line parallel to the axis of curvature of the principal application face or by a non-straight generatrix, in particular a portion of a circle giving the principal application face a slight concavity in a cutting plane perpendicular to the longitudinal axis of the application member. This slight concavity observed in section may have a relative depth less than or equal to 5% of the width of the principal application face or of the section considered.

[0033] The application surface can have an area between 20mm2 and 100 mm2, in particular between 30 mm2 and 50 mm2.

[0034] The application surface of the application device may, in addition to the main application face, have at least one finishing facet in a distal portion, in particular at least two finishing facets, the surface area of ​​each finishing facet being smaller than the surface area of ​​the main application face. This at least one finishing facet may allow for precise application of the composition to the lip contour.

[0035] The surface area of ​​each finishing facet can be between 0.5 mm2 and 5 mm2.

[0036] In particular, the ratio between the surface area of ​​the main application face and the surface area of ​​each finishing facet can be between 10 and 50

[0037] Each finishing facet can be substantially flat.

[0038] At least two of the finishing facets can each extend generally in a plane forming a non-zero angle with the longitudinal axis, in particular an angle between 20° and 70°, preferably between 40° and 50°.

[0039] The application member may include at least one finishing facet, end, being located at a free end of the applicator, perpendicular to the longitudinal axis of the application member and / or the longitudinal axis of the rod.

[0040] Each of said finishing facets can define an edge with the main application face.

[0041] Preferably, the application member comprises at least three finishing facets, a first, end, finishing facet being located at a free end of the applicator, and at least two other, lateral, finishing facets extending towards the proximal end of the applicator from the first finishing facet. This configuration allows for finishing with either of the lateral facets without requiring significant reorientation of the applicator. The end face can generally extend perpendicularly to the longitudinal axis of the application tool.

[0042] The maximum thickness of the application member may be less than or equal to the maximum width of the application member.

[0043] The free end of the application member can be offset relative to the longitudinal axis of the applicator shaft, taking into account the generally curved shape of the main application face. The longitudinal axis of the application member, at the free end of the application member, can be offset from the longitudinal axis of the applicator shaft by a distance t of between 0 and 4 mm. The offset of the application member at its free end can contribute to greater wringing of the back of the application member and promote the accumulation of product in the concavity of the application member.

[0044] The application member may include a body made of a polymer material, in particular a thermoplastic elastomer.

[0045] This body can be extended on the proximal side by a mounting tip on the rod, the attachment to the rod being effected for example by crimping, stapling or otherwise.

[0046] The application element may include a flocking on its surface.

[0047] The container may contain a lip makeup product, in particular a lipstick or lip gloss.

[0048] The wringing lip of the container's wringing element advantageously has corrugations. These corrugations can limit the mechanical deformation stresses applied to the wringing lip due to the dimensions of the application element. This can allow a greater quantity of product to remain on the application element and reduce the risk of detaching flocking fibers present on the surface of the application element.

[0049] By "undulations," we mean a series of depressions and / or protrusions formed by the wringing lip when moving circumferentially around the central axis of the wringing element. These may be alternating concave and convex curves or folds in the circumferential direction. Each undulation of the wringing lip can extend, when viewed from above, along a radially oriented axis. All the axes of the undulations may intersect substantially at the center of the orifice defined by the wringing lip, which is advantageously located on the longitudinal axis of the applicator stem when the applicator is in place in the container.

[0050] The wringing lip may be devoid of ribs and / or slots, for example, slots extending parallel to the longitudinal axis of the stem when the applicator is mounted on the container, or slots extending perpendicular to the longitudinal axis of the stem when the applicator is mounted on the container, or slots inclined with respect to the longitudinal axis of the stem when the applicator is mounted on the container. In particular, the wringing element may be devoid of slots that are substantially closed at rest and extend longitudinally.

[0051] The undulations of the spin-drying element can vary in amplitude and number. For example, the spin-drying element may have between 2 and 12, between 4 and 10, or between 5 and 9. They may be regularly or irregularly distributed. They may all have the same amplitude, or alternatively, be different.

[0052] Two adjacent undulations may have different profiles.

[0053] Advantageously, the free edge of the wringing lip does not extend entirely in a plane, in the absence of constraints.

[0054] The wringing lip can extend at rest, in the absence of an applicator, generally in a cone converging towards the bottom of the container.

[0055] The wringing lip may have a constant thickness, or alternatively a variable thickness. It may be thinner at a point close to its free edge and thicker at a point further from its free edge.

[0056] The spin-drying lip may have, in the circumferential direction, at a given distance from the longitudinal axis of the device, a substantially constant thickness, for example varying by less than 10% over a complete turn.

[0057] The thickness of the spin lip is for example between 0.1 and 0.8 mm. It is for example about 0.2 mm at the free edge and about 0.5 mm at a point on the spin lip further from the free edge, for example at the periphery of the spin lip.

[0058] The wringing lip can unfold under the pressure of the application member before possibly stretching elastically. During the unfolding of the wringing lip, the undulations may tend to flatten out, the wringing lip being observed from the center of the orifice defined by it.

[0059] The orifice of the wringing member can be configured to have the ability to go from a reduced diameter allowing the wringing of the rod to a larger diameter allowing the wringing of the application member, without necessarily requiring a significant elongation of the material of the wringing lip.

[0060] The wringing lip can deform more than the application member when the application member passes through the orifice.

[0061] The undulations can have an amplitude, measured between two opposite ends along the longitudinal axis of the rod when the applicator is mounted on the container, of between 0.5 and 4.5 mm.

[0062] The applicator may include a gripping element carried by the rod at an end opposite to the application member. The gripping element may be removably mounted, in particular by screwing, onto the container. In particular, the gripping element may serve as a closing cap for the container.

[0071] [Fig.8] is a top view of the container of [Fig.1]. Detailed description

[0072] In the following description, identical elements or elements with identical functions bear the same reference numeral. For the sake of brevity, they are not described opposite each figure; only the differences between the embodiments are described.

[0073] In the figures, the actual proportions have not always been respected, for the sake of clarity.

[0074] The dimensions and shapes described are appreciated at rest without mechanical stress related to the use of the applicator.

[0075] Figures 1 to 7 illustrate an example of a device 1 for conditioning and applying a cosmetic product to the lips according to the invention.

[0076] The device 1 comprises a container 2, containing the product to be applied, for example lipstick or lip gloss, and an applicator 3 configured to be mounted removably on the container 2. The product contains, for example, an oil or a wax, and may contain one or more pigments or be free of them.

[0077] The applicator 3 comprises a rod 4, preferably straight as illustrated, which extends along a longitudinal axis X and preferably having a circular cross-section and a diameter D preferably greater than or equal to 6 mm, for example between 6 and 10 mm, better between 6 and 7 mm.

[0078] The applicator 3 includes an application member 5 carried at one end 6 by the rod 4. This application member may have a symmetrical shape with respect to a median plane of symmetry S containing the axis X.

[0079] The applicator 3 can be made of a polymer material, porous or non-porous, typically a thermoplastic elastomer.

[0080] Preferably, the application member 5 is flocked.

[0081] The application member 5 has an application surface 10 comprising a main application face 8, curved around an axis of curvature Y which in the illustrated example is perpendicular to the median plane of symmetry S of the application member.

[0082] The radius of curvature R of the main application face 8 around the Y axis can be constant or variable.

[0083] The radius of curvature R can be constant over most of the length of the main application face 8. This radius of curvature R can be between 10 mm and 20 mm.

[0084] The application member 5 has, in this example, a length Ho, measured along the longitudinal axis X of the rod and out of it, of approximately 15 mm.

[0085] As illustrated in [Fig.5], the application member 5 can have a substantially rectangular cross-section along the main application face 8.

[0086] The free end 13 of the application member 5 can be eccentric relative to the longitudinal axis X, taking into account the generally curved shape of the main application face 8. The longitudinal axis XI of the application member, at the level of the free end 13 of the application member 5, can be offset from the longitudinal axis X by a distance t between 0 and 4 mm.

[0087] As illustrated in [Fig.4], the width W of the application member 5 can be increasing from the rod 4 over a distance Hm, be substantially constant and maximum equal to Lom over a distance Hc along the longitudinal axis X, then decreasing towards the free end 13 of the applicator 3 over a length Hd.

[0088] As illustrated in [Fig.4], the width Wf of the main application face 8 can be substantially constant and maximum over the distance Hc along the longitudinal axis X, then decreasing towards the free end 13 of the applicator 3 over the length Hd.

[0089] For example, Hc is between 8 and 12 mm, Hc being for example 10 mm, and Hd is between 1 and 3 mm, Hd being for example about 2 mm.

[0090] The width W of the cross-section of the application member 5, measured parallel to the curvature axis Y, increases from the rod 4 to a value Lom at the proximal end 11 of the main application face 8.

[0091] The proximal end 11 of the main application face 8 defines an edge 53 extending substantially perpendicularly to the median plane of symmetry S of the application member and located at a distance Hm from the rod 4, this distance being for example between 2 and 3 mm.

[0092] Moreover, as illustrated in [Fig.3], the thickness of the application member 5, measured perpendicular to the curvature axis Y in the median plane of symmetry S, can be increasing from the rod to reach a maximum thickness Lgm, then decreasing towards the free end 13.

[0093] The back 51 of the application member can be substantially flat and parallel to the X axis, from the level of the end 11 of the main application face 8 to the free end 13 of the application member.

[0094] The width Lom is preferably, as illustrated in [Fig.5], greater than the maximum thickness Lgm, which is for example equal to about 7 mm.

[0095] We can see on [Fig.5] that the opposite sides of the section corresponding to the main application face 8 and the back 51 of the application member can be substantially straight and parallel to the curvature axis Y.

[0096] The flanks 52 of the application member may be substantially steep, being for example formed by two inclined surfaces 52a and 52b each having a slight slope with respect to the median plane of symmetry S, for example of less than 30°

[0097] The application member 5 also includes, near the free end 13, three flat finishing facets 20. Each finishing facet 20 has a surface area less than that of the main application face 8, for example at least 10 times less.

[0098] A first finishing facet 20a, of the end, can extend substantially in a plane PI perpendicular to the longitudinal axis X, as seen in [Fig.4].

[0099] A second, lateral finishing facet 20b extends from a side 21 of the first application facet 20a in a plane P2 forming, for example, an angle of approximately 45° with the plane PL

[0100] A third finishing facet 20b, lateral, extends from a side 22 of the first application facet 20a, opposite the side 21, in a plane P3 forming for example an angle of about 45° with the plane PI, as seen in [Fig.4].

[0101] The thickness of the application member, measured perpendicular to the axis X and parallel to the plane of symmetry S, can be substantially constant over the part of distance Hd of the main application face 8, from the free end thereof.

[0102] Thus, the portion of the main application face 8 close to the distal end 13 of the application organ can be oriented substantially parallel to the X axis, just like the back 51.

[0103] As can be seen in [Fig.4], the second and third lateral facets 20b extend over a distance Hd along the longitudinal axis X.

[0104] The application member 5 can be symmetrical with respect to a longitudinal median plane, perpendicular to the axis of curvature Y and perpendicular to the plane of the [Fig.4],

[0105] The applicator 3 has a gripping element 30 connected to one end (not visible) of the rod 4 opposite the end 6. This gripping element 30 allows the applicator 3 to be mounted by screwing it onto a threaded neck 31 of the container 2.

[0106] The interior space 35 of the container 2 contains the cosmetic product.

[0107] The neck 31 includes an opening 36 through which the rod 4 and the application member 5 of the applicator 3 are inserted when the applicator 3 is mounted on the container 2.

[0108] The container 2 includes a wringing member 37 having a wringing lip 38 defining a wringing orifice 39.

[0109] The wringing orifice 39 has a smaller transverse dimension Dt which is less than the maximum width Lom of the application member 5.

[0110] As illustrated in [Fig.7], the lip 38 advantageously comprises undulations, for example four in number, whose axial amplitude As, measured along the longitudinal axis X of the rod 4 when the applicator 3 is mounted on the container 2, is equal to 30°.

[0111] The orifice 39 can be, in top view, circular or alternatively non-circular.

[0112] The stem 4 advantageously includes a portion 40 of reduced diameter which accommodates the lip 38 when the applicator 3 is fully mounted on the container 2. This portion 40 of reduced diameter helps to limit the deformation of the lip 38 in this mounted state.

[0113] When the applicator 3 is extracted from the container 2, the application member 5 will dilate the lip 38 of the wringing member 37, this dilation being significant at a distance quite close to the rod 4, as soon as the end 11 arrives at the wringing orifice.

[0114] The main face 8 is less tightly wound than the back 51, due to its curvature and its closer distance from the X-axis, and can retain a relatively large reservoir of product. The back 51 of the application member is more tightly wound, as are the sides of the application member. The presence of a product reservoir on the main application face 8 contributes to the applicator's autonomy and to the deposition of a thick layer of product, if desired by the user. The concavity of the face The main applicator 8 can closely follow the contour of the lower lip, improving application comfort and product spreading. The end facets 20a and 20b can be used to precisely outline the lips. The ridge formed at the end 11 of the main application face tends to create a barrier, keeping the product within the concavity of the main application face.

[0115] The invention is not limited to the example just described.

[0116] In particular, the cross-section of the application member can be, in variants, substantially square or triangular.
