Description

[0029] The invention may be better understood from reading the following detailed description of non-limiting illustrative embodiments thereof and from examining the appended drawing, in which:

[0030] FIG. 1 is a schematic perspective depiction of a packaging and application set according to the invention,

[0031] FIG. 2 depicts the applicator of FIG. 1 separately, without the covering of the application member,

[0032] FIG. 3 is a side view on arrow III of FIG. 2,

[0033] FIG. 4 is a rear view on IV of FIG. 2,

[0034] FIG. 5 is a section on V-V of FIG. 3,

[0035] FIG. 6 illustrates the applicator of FIG. 1 with the flexible portion in abutment,

[0036] FIG. 7 depicts an embodiment detail of the flexible portion, in longitudinal section,

[0037] FIG. 8 is a view similar to FIG. 7 of an alternative form of embodiment,

[0038] FIG. 9 illustrates an alternative form of embodiment of the flexible portion.

[0039] The packaging and application set 1 depicted in FIG. 1 comprises a product P, for example in the form of loose or compacted powder, present in a cup 3, and an applicator 10 comprising a handle 11 and an application member 20 designed to pick up the product P and apply it to the human keratinous substances that are to be made up, for example to the skin of the eyelids. The product may even be a mascara or a lip gloss.

[0040] Where appropriate, the product P and the applicator 10 may be contained in a case, not depicted, having a base and a lid that closes the base. The base may potentially house several cups each containing a product to be applied. The lid may be articulated to the base.

[0041] As may be seen notably in FIG. 2, the handle 11 is of elongate shape along a longitudinal axis X, preferably rectilinear as illustrated.

[0042] The handle 11 may have a cross section of generally rectangular shape, as can be seen in FIG. 4, for example with a flatness factor L/l of between 1 and 4, L denoting the length and l the width thereof.

[0043] The handle 11, of length D, is extended at its distal end by an extension 21 which constitutes the core of the application member 20.

[0044] In the example considered, this extension 21 is moulded as a single piece in the same material as the handle 11, and has a flattened shape along a plane of flattening which is parallel to the major sides of the cross section of the handle 11. The extension 21 has, for example, as illustrated in FIG. 2 in a face-on view, a contour 22 of substantially oblong shape ending at the end comprising the handle 11 with two opposite edges 21a which are parallel to the axis X.

[0045] The application member 20 may comprise a covering 23, for example made of foam, overmoulded or fixed some other way on the extension 21. This covering 23 may extend beyond the extension 21 along the axis X, at the same end as the distal end of the applicator. The covering 23 may also overhang the extension 21 laterally. In the example of FIG. 1, the covering 23 thus extends all around the extension 21 and forward thereof.

[0046] In an alternative form of embodiment which has not been illustrated, the covering 23 is not made of foam but is constituted by floccing.

[0047] The thickness e of the extension 21 is comprised for example between 0.6 and 2 mm and its greatest width ω is, for example, slightly greater than the length L of the major sides of the cross section of the handle.

[0048] The length D of the handle 11 is for example comprised between 45 and 55 mm. For example the length L is comprised between 4 and 6 mm and the width l is comprised between 3 and 4.5 mm.

[0049] The handle 11 comprises a flexible portion 14, more particularly visible in FIG. 3. This flexible portion 14 is of wavy shape with a succession of elementary patterns 15, one of which has been depicted separately in FIG. 7.

[0050] The flexible portion 14 may as illustrated define waves in the form of crenulations. The flexible portion 14 defines what is referred to as a “concertina” zone.

[0051] The flexible portion 14 is closer to the distal end of the handle 11 than to the proximal end thereof.

[0052] Each elementary pattern 15 in the example considered is in the form of crenulations, with two flexible branches 15a, 15b substantially mutually parallel and perpendicular to the longitudinal axis X, these two branches between them defining a groove 15c that has a rounded bottom 15d. The two branches 15a, 15b are joined together by a connecting part 15e which extends substantially parallel to the axis X. Each branch 15a and 15b is bent over at its opposite end to the intermediate portion 15e, so as to connect to the handle or to an adjacent elementary pattern.

[0053] The branch 15b of an elementary pattern thus connects with the branch 15a of the next pattern via an intermediate portion 15e and therewith defines a groove 15f opening onto the opposite side from the side onto which the groove 15c opens. The grooves may also be referred to as slots when they are relatively narrow.

[0054] The flexible portion 14 forms a succession of crenulations opening alternately onto one side of the applicator and the other, as can be seen notably in FIG. 3.

[0055] The branches 15a and 15b and the intermediate connecting parts 15e have a cross section of flattened shape, as illustrated in FIG. 5, with the major axis A parallel to the plane of FIG. 2 and perpendicular to that of FIG. 3.

[0056] The form factor M/n given by the ratio of the width M of the flexible portion with respect to the thickness n thereof, in cross section, is preferably comprised between 1 and 30.

[0057] The width s of a groove 15c or 15f, mid-way along the length thereof, is preferably comprised between 0.6 and 3 mm.

[0058] The length t of a groove 15c or 15f is, for example, comprised between 1 and 6 mm.

[0059] The width of the grooves allows the angle of deformation to be calculated and altered; the width may be variable, where appropriate, so as to cause the degree of deformation to vary along the flexible portion. Thus, the shape of the elementary patterns may vary.

[0060] When the applicator 10 is being used, the flexible portion 14 may deform as illustrated in FIG. 6, the grooves 15c opening onto one and the same side of the applicator having their opposite sides diverge outwards whereas the grooves opening onto the opposite side of the applicator, in this instance the grooves 15f in the example illustrated, have their opposite sides converging towards the outside. The grooves 15f substantially close up when the flexible part 14 comes into abutment, which means to say when two consecutive branches 15a and 15b come to rest one against the other on the opposite side to the bottom 15d of the groove 15f defined between them, thereby making it more difficult to achieve additional flexural deformation of the flexible part 14. When the deformation is substantially at its maximum, as illustrated in FIG. 6, the axis Y of the distal portion 11b of the handle 11 makes for example an angle α with the longitudinal axis Z of the proximal portion 11a of the handle, which angle is less than 90° and, for example, comprised between 20 and 85°.

[0061] The length at rest of the flexible portion 14, along the axis X, is for example comprised between 3 and 20 mm. The distance u separating two consecutive grooves opening onto opposite sides of the flexible part 11, namely a groove 15c and a groove 15f or a groove 15f and a groove 15c, measured between the median planes of the said grooves which are perpendicular to the axis X, is preferably comprised between 1.2 and 1.6 mm and, for example, takes the value 1.4 mm.

[0062] The radius of curvature at the bottom of the groove 15e or 15f is preferably comprised between 0.2 and 0.5 mm, for example being 0.35 mm.

[0063] In order to use the applicator, the user moves the application member 20 to the surface of the product P in order to load the applicator with product. Next, the user can apply makeup to the skin by moving the applicator with the application member 20 in contact with the skin.

[0064] For preference, the application member 20 is moved with the direction of flattening of the extension 21 substantially parallel to the skin, making the application somewhat gentle. As an alternative, the user can move the application member 20 over the skin with the major faces of the extension 21 substantially perpendicular to the skin. When the applicator is used in this orientation, the flexible portion 14 deforms far less in bending about a geometric axis parallel to the minor sides of the rectangular cross section of the handle and makeup can be applied accurately. This may be of use for applying makeup around the edges of the eyes or the nose for example. The deformability of the applicator is thus greater about a geometric axis parallel to the major sides of the rectangular cross section of the handle than it is perpendicular thereto.

[0065] The invention is not restricted to the example that has just been described.

[0066] In particular, it is possible for the flexible portion not to connect directly to a handle which defines the zone via which the applicator is held but to be connected indirectly via a stem to a member for holding, constituted for example by a closure cap intended to be screwed onto the threaded neck of a container in order to close same, it being possible for such a container to be provided with a member for wringing the stem of the applicator.

[0067] In alternative forms of embodiment that have not been illustrated, the handle 11 at its distal end has a housing that accepts an end fitting for fitting an application member, for example a felt tip or an application member that has a core made from a material different from that of the handle 11, for example metallic or elastomeric.

[0068] The shape of the flexible portion 14 and notably that of the elementary patterns that constitute the waves can be modified.

[0069] Thus, as illustrated in FIG. 8, the elementary patterns may be in the form of arches rather than crenulations.

[0070] For preference, the wavy undulations are centred on a median plane for the applicator member 20, as is the case with the applicator in FIG. 1. As an alternative, the wavy undulations are offset to one side of the applicator as illustrated in FIG. 9, in order to encourage the centring of the grasp with respect to one side of the applicator.

[0071] For preference, the flexible portion comprises identical elementary patterns which repeat, giving periodic waves. As an alternative, the elementary patterns are not identical, giving pseudoperiodic or aperiodic waves so that the force needed to achieve bending evolves.

[0072] For preference, the flexible portion 14 is made in a non-elastomeric material which is the same as that from which the handle 11 is moulded, for example a thermoplastic. As an alternative, the flexible portion 14 is made of a material different from that of the handle 11, notably a less rigid material.

[0073] It is possible to have a different number of grooves on one side of the applicator compared with the other, so as to have two different flexibilities.

[0074] The applicator according to the invention can be used to apply a product to the eyelashes or the eyebrows, notably mascara, or to the lips, notably a lip gloss.

[0075] The expression “comprising a” is synonymous with “comprising at least one”.
