Description

[Technical Field]

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

[0002] Applicators are known that have an applicator member with a body defining facets used for applying the composition.

[0003] The '691 application describes an applicator member having a body with a rotationally symmetric overall shape, excluding facets of generally oval outer shape that extend obliquely to the distal end of the applicator member. The larger diameter region of the body can be at the base of the facets or between their proximal and distal ends. The maximum width of the facets is in any case reached after the body has reached its maximum diameter, and the maximum width of the facets is located on the region of the body where the width decreases.

[0004] The '699 application describes an applicator member having a body with a cylindrical portion of circular or polygonal cross section extended at its distal end by a generally conical tip, with oblique facets extending over a portion of the cylindrical portion and over the tip, the width of the facets being greatest at the junction of the cylindrical portion and the tip.

[0005] In order to apply a cosmetic composition such as a concealer product, it is necessary not only to be able to apply the composition in a sufficiently thick layer over a relatively wide area without the need to reapply the applicator too frequently, but also to be able to apply it precisely without the risk of irritating particularly sensitive skin in those areas, or even causing burning in the eyes.

[0006] Existing applicators are not all satisfactory, having applicator members that are either very wide but not very precise, such as powder puff types, or relatively narrow and precise, such as angled end types that are not well suited to covering large areas quickly and that often deposit too little composition in a single gesture. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] International Publication No. 2020 / 149203 [Patent Document 2] International Publication No. 2022 / 004176 Summary of the Invention [Problem to be solved by the invention]

[0008] Thus, there is a need for further improvements in applicators designed for applying cosmetic products such as concealer, and more generally any cosmetic product that is applied to the skin or lips.

[0009] In particular, it is advantageous to be able to apply the cosmetic composition precisely, in relatively large amounts and / or with a lower risk of burning the skin. [Means for solving the problem]

[0010] The present invention aims to meet this need and is achieved by: a body having a longitudinal axis and a distal end; - at least one facet extending obliquely relative to said longitudinal axis, the facet having a width that increases and then decreases in the direction of said distal end, and having two substantially straight, preferably straight, end faces adjacent the distal end of the applicator member, the two end faces defining an obtuse angle therebetween; This is achieved by proposing a cosmetic applicator having an applicator member having:

[0011] The term "substantially straight" should be understood to mean that, over an end face length of at least 2.5 mm, better still at least 3 mm, better still at least 3.5 mm, or even at least 4 mm, the end face extends along a straight line or along an arc of a circle having a curvature large enough to approximate a straight line with a deviation of less than 0.5 mm, better still at least 0.3 mm, and better still at least 0.1 mm. If the end face is not straight, the obtuse angle is measured between the approximating straight lines.

[0012] The applicator therefore remains relatively soft at its tip, limiting the risk of unpleasant burning in the sensitive area of ​​the eye, thus allowing risk-free access to the eye and optimal application of the composition.

[0013] According to another of its aspects, a further object of the present invention, independently or in combination with the above, is - a longitudinal axis, a distal end, and a maximum value L that increases in the direction of the distal end over at least a portion of the length of the body, as measured in a front view; max a body having a width passing through the - at least one facet extending obliquely to said longitudinal axis at least partially along said portion of said body of increasing width, said facet having a width that increases and then decreases in the direction of the distal end, said portion of said body of increasing width having a maximum width L max and at least one facet passing through its maximum width at a point at which the point reaches the distal end and at a distance substantially the same as the distance from the distal end measured along the longitudinal axis. A cosmetic applicator having an applicator member having:

[0014] The term "substantially the same distance" refers to the distance d from the distal end of the facet at the point where the facet is at its widest point. facet is less than x% (i.e., |dfacet -d body | / d facet (equal to x / 100, where x% is equal to 5%, preferably even 2%, more preferably even 1%, at the point where the body is at its maximum width, the distance d from the distal end of the body body is to be understood as being equal.)

[0015] Thanks to this, according to another aspect of the invention, a relatively wide area available for the application of the product is obtained, it is possible to apply a relatively large amount of product, spread it more easily, and at the same time, thanks to the shape of the beveled surface that decreases in width in the direction of the distal end of the applicator member, the possibility of accurate application is retained.

[0016] Thus, such an applicator is particularly suitable for the application of concealer products, but may also be suitable for the application of lip gloss, which is generally applied in a relatively thick layer, among other cosmetic compositions.

[0017] The following applies to both the first and second aspects of the invention.

[0018] The obtuse angle is preferably greater than 90° and less than 120°, more preferably even less than 100°, which makes it possible to retain the sufficiently tapered characteristic for accuracy.

[0019] Beveled surface Preferably, the beveled surface is flat, which maximizes the contact area with the skin.

[0020] The beveled surface preferably has a substantially polygonal outer shape, and advantageously is in the shape of a convex kite.

[0021] If h is the distance measured along the longitudinal axis of the applicator member between the distal end and the location where the width of the beveled surface is maximum, the long side of the beveled surface is located at a distance from the distal end of the applicator member that is longer than h.

[0022] The ratio of the axial distance over which the short sides define the facets to the overall axial dimension of the facets is between one-fourth and one-third.

[0023] Applicator member The width of the applicator member, measured in a side view (viewing orientation perpendicular to that of the front view), may increase from the proximal end of the applicator member to the proximal end of the facet. This allows for a further increase in the surface area of ​​the facet, since the cross section of the applicator member is larger at the point where it begins.

[0024] The applicator member may have a cross section between the facets and the proximal end of the applicator member that decreases, particularly continuously, in the direction of the proximal end of the applicator member.

[0025] The applicator member preferably has a shape that is symmetrical about a median plane of symmetry that is generally perpendicular to the facets.

[0026] Preferably, the facets are inclined at an angle of between 30° and 40° relative to the longitudinal axis of the applicator member.

[0027] Width L max is wider than 6mm and narrower than 8mm, and even better still, 6.5mm to 7.5mm.

[0028] The body of the applicator member is preferably flocked.

[0029] When viewed from the side, the applicator member has a straight front end extending from the facet toward the proximal end of the applicator member and a straight rear end extending in the opposite direction along substantially the entire length of the body of the applicator member, the front end preferably being steeper than the rear end.

[0030] The applicator member is located at one end of a stem, which is connected at its other end to a closure cap.

[0031] Packaging and Application Equipment According to another of its aspects, the present invention further provides a method for producing a composition comprising: a container containing a cosmetic composition to be applied to the skin or lips, preferably having a wiping member; an applicator as defined above; A packaging and application device comprising:

[0032] The shape of the applicator member allows it to be wiped well opposite the facets and therefore kept clean and precise.

[0033] The invention may be better understood by reading the following detailed description of non-limiting embodiments thereof and by studying the accompanying drawings, in which: [Brief explanation of the drawings]

[Figure 3] FIG. 2 is a front elevational view of the applicator member; [Figure 4] 4 is a side view of the applicator member taken along arrow IV in FIG. 3; FIG. [Figure 5] FIG. 2 is a cross-sectional view of the applicator member. DETAILED DESCRIPTION OF THE INVENTION

[0035] FIG. 1 shows a packaging and application device 1 according to the invention, comprising an applicator 2 and a container 3 containing a product F to be applied to the skin or lips, for example a concealer product.

[0036] The container 3 has at the top a threaded neck 4 onto which a closure cap 5 can be screwed.

[0037] A wiping member 6 having a wiping lip 6a may be mounted within the neck portion 4 as shown.

[0038] The applicator 2 of longitudinal axis Y has a handle 7 connected at one end to a cap 5 used as a gripping member, and at the other end supports an applicator member 10 used to apply the composition F to the skin or lips.

[0039] When the container is closed, the lip 6a of the wiping member 6, which may have a narrowing in the area located at the lip 6a, is designed to wipe the handle 7 of the applicator.

[0040] The applicator member 10 is shown alone in Figures 2 to 4 .

[0041] The applicator member has a body 11 extended by a fixed end 12 intended to be inserted into a corresponding housing of the handle 7 .

[0042] The body 11 and the end piece 12 may be manufactured by injection molding a thermoplastic material, in particular an elastomer.

[0043] The body 11 is covered with flocking 13 which is visible in FIG. 1 and not shown in FIGS.

[0044] The body 11 has facets 20 which are advantageously flat as shown and extend obliquely to form an angle a with the longitudinal axis Y, this angle a being approximately 34° in the example in question.

[0045] When viewed from the front, as in Figure 3, the facets 20 have the overall shape of a kite with two long end faces 21 and two short end faces 22, the facets being symmetrical about the median plane M of the applicator member.

[0046] End faces 21 and 22 may be straight, with a radius of curvature R at their vertices of less than 0.5 mm, for example a radius of curvature R of about 0.3 mm.

[0047] The angle b formed between the end faces 22 is an obtuse angle, for example, 90° to 100°, and more specifically, approximately 95°.

[0048] If d denotes the length of facet 20 measured along axis Y, then the width of facet 20 will be at a maximum at the junction of end surface 21 and end surface 22, a distance h from distal end 23 of the applicator member, measured along axis Y, and will be substantially L max reaches.

[0049] The distance d is, for example, between 7 mm and 13 mm, and better still between 9 mm and 11 mm.

[0050] The ratio h / d is, for example, 0.25 to 0.33.

[0051] The overall length T of the main body 11 is, for example, 15 mm to 20 mm.

[0052] When the applicator member is viewed from the side, as in FIG. 4, the body 11 is bounded on the left by a front end 15 extending between the apex 26 of the facet 20 and an end face 17 located at the proximal end of the body 11, and on the right by a rear end 16 extending between the distal end 23 and the end face 17.

[0053] Ends 15 and 16 are straight in the example in question, with front end 15 being steeper relative to longitudinal axis Y than rear end 16. Thus, the width w of applicator member 10 increases between end face 17 and vertex 26 in a cross section containing axis Y and perpendicular to median plane M.

[0054] When the body is viewed from the front, as in Figure 3, it is delimited by linear left and right end portions 18 which form the same non-zero angle, e.g., 2-3 degrees, with axis Y. The distance measured between ends 18 is from end face 17, which is e.g., about 5 mm (and which corresponds substantially to the diameter of shank 7), to the point where it is L at the junction between end faces 21 and 22. max It increases continuously until it reaches

[0055] Between the proximal end of body 11 and apex 26 of facet 20, the cross-section of body 11 can increase continuously, and this cross-section is not rotationally symmetric about axis Y, but has a shape that varies, for example, from approximately circular at end face 17 to approximately triangular (or a convex kite quadrilateral type with two short sides forming a significant angle between them) at apex 26, as shown in FIG. 5.

[0056] To use the applicator 2, a user can extract the applicator member 10 from the container and apply the composition F using the facets 20.

[0057] The relatively large area of ​​the applicator member provides the applicator with autonomy, making it possible to deposit a sufficiently large amount of composition to obtain the desired coverage. The composition present on the facets can be easily spread.

[0058] The applicator tip can be used to precisely apply Composition F close to the eye without risk of burning the skin.

[0059] The invention is not limited to the examples described here: it is possible to modify the shape of the facets, for example by slightly curving the end faces or by providing a slight curvature to the facets. [Explanation of symbols]
