Description

Title of the invention: Cosmetic applicator technical field

[0001] The present invention relates to a cosmetic applicator for applying a cosmetic composition to the skin or lips. Previous technique

[0002] Applicators are known comprising an application element having a body defining a facet used for the application of the composition.

[0003] Application WO 2020 / 149203 describes an application member having a body of generally symmetrical revolution, except for a facet with a generally oval contour, extending obliquely to the distal end of the application member. The region of greatest diameter of the body may be located at the base of the facet or between its proximal and distal ends. The maximum width of the facet is reached in each case after the body has reached its maximum diameter, the maximum width of the facet being located in a region of the body whose width decreases.

[0004] Application WO 2022 / 004176 describes an application element comprising a body having a cylindrical portion, of circular or polygonal cross-section, extended at its distal end by a generally conical point, an oblique facet extending over a part of said cylindrical portion and over the point. The width of the facet may be greatest at the junction of said cylindrical portion and the point.

[0005] To apply a cosmetic composition such as an under-eye concealer, it is necessary not only to be able to apply the composition in a layer of sufficient thickness over a relatively large area without having to reload the applicator too frequently, but also to be able to do so precisely without risk of irritating the skin, which is particularly sensitive in this area, or even of stinging the eye.

[0006] Existing applicators do not offer complete satisfaction by presenting either a puff-type application element, very wide but insufficiently precise, or a beveled tip type, relatively narrow and precise but poorly adapted to quickly cover a large surface and depositing a quantity of composition in a single movement which is often too small. Description of the invention

[0007] There is therefore a need to further improve applicators intended for the application of a cosmetic product such as concealer, and more generally any cosmetic product to be applied to the skin or lips.

[0008] In particular, there is an advantage in being able to apply the cosmetic composition precisely and with less risk of pricking the skin. Summary of the invention

[0009] The invention aims to meet this need, and it achieves this by proposing a cosmetic applicator comprising an application element including: - A body having a longitudinal axis and a distal end, - at least one facet extending obliquely with respect to the longitudinal axis, this facet having a width that increases and then decreases towards the distal end, the facet having two substantially straight edges, preferably straight, adjacent to the distal end of the application member, these two edges defining an obtuse angle between them.

[0010] By "substantially straight" it should be understood that the edge extends along a straight line or along an arc that has a curvature large enough to approach a straight line with a deviation of less than 0.5 mm, preferably 0.3 mm, even better 0.1 mm, over an edge length of at least 2.5 mm, preferably at least 3 mm, even better at least 3.5 mm, or even at least 4 mm. The obtuse angle is measured between approaching lines when the edges are not straight.

[0011] Thus, the applicator remains relatively soft at its tip, and the risk of unpleasantly pricking the sensitive area of ​​the eye is limited. This allows for safe contact with the eye and optimal application of the product.

[0012] According to another aspect of the invention, the invention also relates, independently or in combination with the foregoing, to a cosmetic applicator comprising an application element including: - A body having a longitudinal axis, a distal end and a width, measured in front view, which increases in the direction of the distal end over at least a portion of the length of said body and passes through a maximum Lmax, - at least one facet extending obliquely with respect to the longitudinal axis, at least partially along the portion of the body of increasing width, this facet having a width which increases then decreases in the direction of the distal end and passes through a maximum width substantially at the same distance from the distal end, measured along the longitudinal axis, as where said portion of increasing width reaches its maximum width Lmax.

[0013] By "approximately the same distance" it should be understood that the distance dfacet to the distal end where the width of the facet is maximum is equal to that dbody of the body where it is of maximum width, to within x%, that is to say that ldfaCette-dbodyl / d facet <x / 100 avec x% égal à 5%, mieux à 2% ou encore mieux à 1%.

[0014] Thanks to the invention according to this other aspect, we benefit from a surface available for the application of the product which is relatively large, is capable of being loaded with a relatively large quantity of product, and facilitates its spreading, while retaining a possibility of precise application thanks to the shape of the facet, the width of which decreases towards the distal end of the application organ.

[0015] Such an applicator is therefore particularly suitable for the application of an anti-keratosis product, but can also be suitable for the application of a lip gloss which is generally applied in a thick layer, among other cosmetic compositions.

[0016] The following applies equally to the first aspect of the invention as to the second.

[0017] The obtuse angle is preferably greater than 90° and less than 120°, better at 100°, which allows it to retain a sufficiently tapered character to be precise.

[0018] Preferably, the facet is flat, which maximizes the contact area with the skin.

[0019] Preferably, the facet has a substantially polygonal contour, advantageously in the shape of a convex kite.

[0020] If h is the distance, measured along the longitudinal axis of the application organ, between the distal end and the location where the width of the facet is maximum, the large sides of the facet are located at a distance from the distal end of the application organ greater than h.

[0021] The ratio between the axial distance along which the small sides delimiting the facet extend, relative to the total axial dimension of the facet, can be between 1 / 4 and 1 / 3.

[0022] The width of the application member, measured in side view (in an observation direction perpendicular to that of the front view), can increase from a proximal end of the application member to a proximal end of the facet. This further increases the surface area of ​​the facet, since the cross-section of the application member is larger where it begins.

[0023] The application member may have, between the facet and the proximal end of the application member, a cross-section decreasing, in particular continuously, towards the proximal end of the application member.

[0024] Preferably, the application member has a symmetrical shape with respect to a median plane of symmetry, generally perpendicular to the facet.

[0025] Preferably, the facet is inclined at an angle between 30 and 40° with the longitudinal axis of the application member.

[0026] The width Lmax can be greater than 6 mm and less than 8 mm, preferably between 6.5 and 7.5 mm.

[0027] Preferably, the body of the application member is flocked.

[0028] The application organ may, when viewed from the side, have a straight front edge extending from the facet towards the proximal end of the application organ and a straight rear edge extending on the opposite side over substantially the entire length of the body of the application organ, the front edge preferably being more sloping than the rear edge.

[0029] The application member may be located at one end of a rod connected at the other end to a closing cap.

[0030] The invention also relates, according to another aspect, to a conditioning and application device comprising: - A container containing a cosmetic composition to be applied to the skin or lips, this container preferably having a wringing mechanism, - an applicator as defined above.

[0031] The shape of the application organ allows it to be well wrung out on the side opposite the facet, and thus to remain clean and precise. Brief description of the drawings

[0032] The invention will be better understood upon reading the detailed description that follows, a non-limiting example of its implementation, and upon examination of the accompanying drawing, in which:

[0033] [Fig-1] represents in partial and schematic longitudinal section, a device of conditioning and application according to the invention,

[0035] [Fig.3] is a front elevation view of the application member,

[0036] [Fig.4] is a side view of the application member, according to arrow IV of [Fig.3], And

[0037] [Fig.5] is a cross-section of the application member. Detailed description

[0038] Figure 1 shows a conditioning and application device according to the invention, comprising an applicator 2 and a container 3 containing a composition F to be applied to the skin or lips, for example an anti-semen product.

[0039] The container 3 has a threaded neck 4 in its upper part, onto which a closing cap 5 can be screwed.

[0040] A wringing element 6 comprising a wringing lip 6a can be mounted in the neck 4, as illustrated.

[0041] The applicator 2, with longitudinal axis Y, has a rod 7, one end of which is connected to the cap 5, which serves as a gripping member, and the other end carries an application member 10, which is used to apply the composition F to the skin or lips.

[0042] The lip 6a of the wringing member 6 is adapted to wipe the rod 7 of the applicator, which may have a narrowing in the region that comes to be positioned at the level of the lip 6a when the container is closed.

[0043] The application member 10 is shown in isolation in figures 2 to 4.

[0044] It comprises a body 11 extended by a fixing tip 12, intended to be inserted into a corresponding housing of the rod 7.

[0045] The body 11 and the tip 12 can be made by injection molding of a thermoplastic material, in particular elastomer.

[0046] The body 11 is covered with a flocking 13, visible on [Fig. 1] and not shown on figures 2 to 4.

[0047] The body 11 has a facet 20, which is advantageously flat, as illustrated, and extends obliquely at an angle α with the longitudinal axis Y, this angle α being of the order of 34° in the example considered.

[0048] When viewed from the front as in [Fig. 3], the facet 20 has a shape general kite shape, with two large edges 21 and two small edges 22, the facet being symmetrical with respect to a median plane M for the application organ.

[0049] The edges 21 and 22 can be straight, with a radius of curvature R less than 0.5mm at their apex, for example with a radius of curvature R of the order of 0.3mm.

[0050] The angle b formed between the edges 22 is obtuse, being for example between 90° and 100°, in particular close to 95°.

[0051] If d denotes the length of the facet 20 measured along the Y axis, the width of the facet 20 is maximum and reaches substantially Lmax at Injunction of the edges 21 and 22, at a distance h from the distal end 23 of the application member, measured along the Y axis.

[0052] The distance d is for example between 7 and 13 mm, better between 9 and 11 mm.

[0053] The h / d ratio is for example between 0.25 and 0.33.

[0054] The total length T of the body 11 is for example between 15 and 20 mm.

[0055] When the application organ is viewed from the side, as in [Fig.4], the body 11 is delimited on the left by an anterior border 15 extending between the apex 26 of the facet 20 and an edge 17 located at the proximal end of the body 11, and on the right by a rear border 16, extending between the distal end 23 and the edge 17.

[0056] The edges 15 and 16 are straight in the example considered, the front edge 15 being more steep than the edge 16, relative to the longitudinal axis Y. Thus the width w of the application member 10 increases between the edge 17 and the vertex 26, in a cutting plane containing the axis Y and perpendicular to the median plane M.

[0057] When the body is viewed from the front as in [Fig. 3], it is delimited by straight left and right edges 18, making the same non-zero angle with the Y-axis, for example, a few degrees. The distance measured between the edges 18 increases continuously from edge 17 where it is for example about 5mm (and corresponds approximately to the diameter of the rod 7) until reaching Lmax at the junction between edges 21 and 22.

[0058] Between the proximal end of the body 11 and the apex 26 of the facet 20, the cross-section of the body 11 can grow continuously, this cross-section being non-symmetrical of revolution around the Y axis, having for example a shape passing from generally circular at the level of the edge 17 to generally triangular (or convex kite-type quadrilateral having two short sides forming a fairly large angle between them at the level of the apex 26, as illustrated in [Fig.5].

[0059] To use the applicator 2, the user extracts the application member 10 from the container and can apply the composition F using the facet 20.

[0060] Its relatively large surface area provides autonomy to the applicator and allows for the application of a sufficient quantity of composition to obtain the desired coverage. The composition on the facet can be easily spread.

[0061] The tip of the applicator can be used to precisely apply composition F close to the eye, without risk of pricking the skin.

[0062] The invention is not limited to the example just described. For example, the shape of the facet can be modified by slightly curving the edges or by giving the facet a slight curve.
