Abstract

The container and applicator, in which the applicator tip can be in the form of a brush, comb or sponge with a wide variety of lengths and cross-sections, has an internal scraper (40) to control the amount of the product collected by the tip. The container (10) is equipped with a regulator that modifies the shape of the scraper by elongation or compression, or by twisting one end in relation to the other. The scraper is adjusted, for example, by rotating a button (50) in a spiral groove (51) in the outer wall of the container, causing an inner sleeve (21) to which the scraper is attached to extend or retract.

Description

The present invention relates to devices for packaging and applying a cosmetic product, to be applied to the skin, mucous membranes or integuments, makeup or care, for example mascara for eyelashes or eyebrows.

The invention applies to packaging and application devices comprising a wiper member and means for acting thereon to modify its inner section and spin more or less an applicator engaged through it.

Such devices are known for example patent applications French FR 2 563 712 , FR 2,580,479 , FR 2 515 941 , patents US 4,194,848 , US 4,609,300 , US 6,676,320 , US 4,261,376 , US 4,332,494 , US 4,333,928 , US 6,503,487 , and requests EP-A-1,060,686 , DE-A1-32 40 151 , WO 98/00045 , EP-A2-0 219 138 , JP 11-004714 , JP 10-117840 , JP 2001-061545 , JP 2001-061548 , JP 11-244043 , JP 2000-037227 , JP 10 9128 , JP 08-289815 , JP 2001-327326 , JP 2001-000239 , JP 2000 66642 , JP 08-228829 or JP 2001-000239 .

We also know by the request FR 2,605,198 a set of makeup comprising a stiffening device for adjusting the rigidity of the wiper lip of the wiper member.

In these patent applications and patents, the applicator comprises a mascara brush of generally cylindrical shape, straight core extending in the extension of the rod.

It is also known from the patent US 4,628,950 a cosmetic product applicator comprising an applicator member and two dewatering members.

We know by the request FR 2,738,125 a mascara conditioning device configured such that the user can adjust the spin by pressing on the tank made of a flexible material. In this application, the applicator comprises a handle and tufts of bristles implanted parallel to the middle plane of the handle.

The patent US 4,241,743 relates to a mascara application device comprising a wiper member, means for acting thereon to modify its inner section and an applicator comprising a brush comprising a twisted core extending along a curvilinear axis, the brush being of circular cross section, of decreasing diameter towards its free end.

In known variable wiper devices, the amount of product present on the applicator can be modified by the user by acting on the setting of the wiper member.

There is a need to further improve the devices allowing the user to modify himself the amount of product that the applicator loads, and in particular to offer the user the ability to vary in a relatively large way this amount of product without affecting the quality of makeup or ease of use of the device.

The invention aims in particular to meet this need.

• un récipient pour contenir le produit,
• un élément d'application pour appliquer le produit, comportant une âme et des éléments en saillie s'étendant à partir de l'âme, l'élément d'application définissant une surface enveloppe présentant au moins une section transversale excentrée par rapport à l'âme et/ou non circulaire,
• au moins un organe d'essorage de l'élément d'application, et
• au moins un organe de réglage pour agir sur l'organe d'essorage afin de modifier sa section intérieure, et ainsi essorer plus ou moins l'élément d'application engagé à travers lui.

According to one of its aspects, the subject of the invention is a device for packaging and applying a product, comprising:

• a container for containing the product,
• an application member for applying the product, having a core and protruding members extending from the core, the application member defining an envelope surface having at least one eccentric cross section relative to the soul and / or non-circular,
• at least one wiper member of the application element, and
• at least one adjusting member for acting on the wiper member to modify its inner section, and thus more or less wringing the application member engaged therethrough.

The particular shape of the envelope surface in the present invention allows greater load variation of the applicator element as the section of the wiper member varies.

The range of variation of the inner section of the wiper member may be chosen to have an effect on the product load of the application member and the result of the application.

Thanks to the invention, the user can modify as desired the product loading of the applicator element and create load differences on the applicator element, thus forming, for example, zones heavily loaded with product. and areas with little or no product load.

Such a device is reliable in operation and easy to use and can provide new makeup effects, if any.

The adjustment member may be movable in translation and / or in rotation relative to the wiper member.

The movement of the wiper member may be a pure rotation or a pure translation, or a combination of both, for example a helical movement, or a succession of one or more rotation (s) and / or a several translation (s), or be a more complex motion, comprising at least one instantaneous component of rotation and / or translation.

The device may comprise only one wringing member.

The application element may have protruding elements of different lengths, to promote the retention of the product in certain areas and a stronger spin in other areas, depending on the setting made by the user. This adjustment can be chosen in particular so that the projecting elements of greater length of the application element are more wrung out than the projecting elements of shorter length, to comb and separate the eyelashes or eyebrows. The application element can thus comprise, after spinning and thanks to the adjustment made by the user, areas virtually devoid of product, to separate more easily eyelashes or eyebrows.

The user may, for example, first bring the eyelashes into contact with an area of the application element that is relatively loaded with product, and then with another region that is less loaded with product, to separate the eyelashes. The user can still bring the eyelashes only in contact with one of the areas only of the application element, depending on the makeup he wants.

The present invention can make it possible to obtain spin differences greater than those obtained with a known brush with symmetry of revolution, for example cylindrical or in a rugby ball, thanks to the shape of the application element.

ENVELOPE SURFACE

In the case of a brush, the envelope surface is defined by the free ends of the bristles.

In the case of a comb, the envelope surface is defined by the cross-sectional shape of the comb.

ELEMENTS OF APPLICATION

OTHER ELEMENTS OF APPLICATION

The application element may comprise a flocked tip or not. The tip may comprise a body of elastomeric material.

The tip may further include a felt or foam.

SPINNING SYSTEM

The deformation of the wiper member may result from the relative movement of a first and a second element, which may be arbitrary.

• un premier élément ayant un axe et comportant au moins une fente s'étendant non entièrement perpendiculairement à cet axe,
• un deuxième élément au moins partiellement engagé à l'intérieur du premier et pouvant tourner par rapport à celui-ci autour de l'axe et pouvant également se déplacer axialement dans le premier élément, ce deuxième élément comportant au moins un ergot engagé dans la fente et visible depuis l'extérieur du dispositif,
• la fente et l'ergot étant configurés de telle sorte qu'un déplacement de l'ergot dans la fente lors de la rotation relative des premier et deuxième éléments provoque un déplacement axial des deux éléments.

The device may comprise in an exemplary implementation, in order to act on the wiper member:

• a first member having an axis and having at least one slot extending not entirely perpendicular to that axis,
• a second element at least partially engaged within the first and rotatable relative thereto around the axis and also being able to move axially in the first element, this second element comprising at least one lug engaged in the slot and visible from the outside of the device,
• the slot and the lug being configured so that a displacement of the lug in the slot during the relative rotation of the first and second elements causes an axial displacement of the two elements.

The lug may be unique, and have any shape, for example of circular section or not, being monolithic or not.

The device may comprise on its outer surface at least one apparent mark associated with a particular relative position of the first and second elements, for example several marks corresponding to different positions of the pin in the slot, each mark comprising for example at least one alphanumeric character or pictogram.

The slot extends for example angularly less than 180 °, for example about 120 °, around the aforementioned axis. The slot may have at least one smooth or notched edge. The presence of at least one notch can facilitate, if necessary, the positioning of the second element relative to the first in less than a predefined position. The existence of at least one notch may also form at least one hard point whose crossing by the pin is perceptible by the user and, where appropriate, may be accompanied by the emission of an audible click. . The presence of at least one notch can further facilitate the maintenance of the lug in a predefined position during the transport of the device, in a handbag for example.

The slot may have an inclination, relative to the axis, chosen so that the axial stroke of the second element in the first, between the extreme positions of the lug in the slot, is between about 1 mm and about 10 mm, for example between 1 mm and 8 mm, for example still between 2 mm and 5 mm.

The lug may have a length that is greater than or equal to the thickness of the wall of the first element traversed by the slot, which can improve the retention of the second element in the first element and the visibility of the lug. The lug can still have a length less than the thickness of the wall of the first element through which the slot, which can facilitate its implementation.

The first and second members may be arranged to allow insertion of the lug into the slot by elastic deformation of at least one of the first and second members when the second member is moved within the first member.

The first element may have on its inner surface at least one notch that can facilitate the movement of the lug between the end of the first element for introducing the second element and the slot. This notch may for example lead to the aforementioned end.

The lug can have a free end rounded or chamfered, which can improve the aesthetics and facilitate its implementation in the slot.

The first element can be made in one piece by molding plastic material. The same can be said of the second element.

In an exemplary implementation of the invention, the second element has an end portion that extends continuously out of the first element. This end portion may include an outer skirt, which may be striated or grained to facilitate its training by the user.

The second element may also include a body that is closed at one end. When the end portion has an outer skirt, the outer skirt may be arranged to extend around the bottom of the body.

The body may constitute the container containing the product, in particular a cosmetic or dermatological product, for example mascara.

The application element may in particular be removably attached to the first element to be extracted from the device for the application and then reintroduced into the device to be reloaded product.

The applicator element is arranged to be housed in the second element when it is in place on the container.

The wiper member is arranged to be deformed more or less according to the relative positioning of the first and second elements. It may comprise an insert or be made monolithically with one of the first and second elements.

The wiper member is for example arranged on one of the first and second elements, being for example fixed on the second element, and can be deformed by the other element according to the relative axial positioning of the two elements.

The wiper member may be arranged to deform in elongation or compression. The wiper member may be arranged to deform in spacing.

In the case of elongation deformation, the wiper member comprises for example a central portion provided with a transverse wall, for example a bottom wall, through which an opening and the first element may comprise an inner extension which presses more or less on this bottom wall according to the relative positioning of the first and second elements and thus modifies the shape of the opening, for example by widening more or less.

In the case of compression deformation, the deformable dewatering member is for example made of an elastically compressible material such as a foam.

This elastically compressible material may have a hardness that depends on its degree of compression, which may allow the user to modify the characteristics of the spin, for example.

The wiper member may be arranged to deform in shear, the device comprising for example a control member configured to rotate a first end of the wiper member relative to a second end of the wiper member. 'spinning.

The device may further comprise a button adapted to be driven in translation in a direction perpendicular to a longitudinal axis of the device.

The wiper member may comprise a flange defining with the central portion an annular groove in which is engaged the second element.

The aforementioned transverse wall may comprise at least one slot facilitating the deformation of the wiper member by pressing against it the extension of the first element. The transverse wall may for example comprise a plurality of substantially radial slots.

The inner extension of the first element acting on the wiper member can be made in one piece by molding material with the rest of the first element. This inner extension may have a tubular shape. The inner extension can play a spin function as well, if necessary.

In an exemplary implementation of the invention, the wiper member comprises a plurality of tongues integrally molded with one of the first and second elements and the other of the first and second elements has a surface against which these tongues can bear against the relative axial positioning of the first and second elements.

The aforementioned surface may be arranged in such a way that the tabs flex more or less depending on the relative axial positioning of the first and second elements.

The tabs define an opening for wringing the applicator member, and this opening may thus have a dimension that the user can vary by rotating the first member relative to the second member. The surface serving to support the tongues is for example conical, converging towards the interior of the container.

The first element may comprise a generally cylindrical outer wall, through which the slot passes, and this outer wall may have, for example, substantially the same external diameter as the end portion of the second element.

The device may comprise a rod provided with a necking in a region of the rod which is positioned, when the device is closed, facing the wiper orifice. This shrinkage may extend over a length greater than or equal to the maximum displacement displacement of the second element relative to the first. This can avoid or reduce the stresses exerted by the rod on the wiper member when the applicator element is in place, regardless of the angular orientation of the first element relative to the second.

The device 1 for packaging and application shown in Figures 1 and 2 comprises a first member 10 and a second member 20 rotatable relative to the first member 10 about the longitudinal axis X of the device.

The device 1 also comprises an applicator 30 which comprises in the example under consideration a pin 31 of axis X, provided at one end with an application element 100 and at the other end with a gripping member 33.

The first element 10 comprises, as can be seen in FIG. 1, a generally cylindrical wall 11, of axis X, prolonged in the upper part by a neck 12 which is connected below a transverse wall 13.

The first element 10 also comprises, in the example illustrated, an inner extension 14 of tubular shape, defining an introduction cone 15 for the applicator element, converging towards the inside of the container, and provided at its lower end with an annular bead 16.

The second element 20 comprises, in the example considered, a generally tubular body 21, X axis, closed at its lower end by a bottom 22, thus constituting a container containing the product. The lower portion 23 of the body 21 is surrounded by an outer skirt 24 whose outer surface is grained, as can be seen in Figure 2. It could alternatively (not shown) be striated.

The skirt 24 joins topally a transverse wall 25, which is connected perpendicularly to the body 21. The wall of the latter thickens above the transverse wall 25, so as to form a cylindrical guiding surface 26, of suitable outside diameter to the inner diameter of the lower end of the wall 11. The height of the guide surface 26 is sufficient so that, regardless of the angular position of the second element 20 relative to the first element 10, the surface 26 remains substantially in contact with the the inner surface of the wall 11.

The body 21 has in the upper part, on its radially outer surface, an annular bead 27 which serves to attach a wiper member 40. The latter comprises in the upper part an annular rim 41 arranged to snap on the bead 27. This flange 41 is connected to a tubular skirt 43 extending in the annular space formed between the inner extension 14 and the upper part of the body 21.

The wiper member 40 comprises in the lower part a transverse wall 45 traversed by a central orifice 46 and by a plurality of slots 47 forming between them fins 48, as can be seen in FIG.

In the variant illustrated in Figure 4, the transverse wall 45 is traversed by a single orifice 46 of circular section, without the slots 47. This can provide, if necessary, a sealing contact of the wiper member on the rod 31 of the applicator, storage for example.

The body 21 serves as a container and contains a product P, especially cosmetic, makeup or care, for example mascara.

The second element 20 is provided with a lug 50 and the first element 10 has a slot 51 passing through the wall 11 and whose longitudinal axis Y extends for example along a portion of a helix, over an angular extent for example of Around 120 ° around the X axis.

FIG. 5 illustrates the possibility for the slot 51 to extend differently than in a single helix portion, and in FIG. 6 the possibility for at least one of the edges of the slot 51 to include notches 80. At least one of them may for example be associated with a reference 81 useful to the user, such as a number or a letter.

The inclination of the slot 51 allows for example a maximum stroke d in the axial direction of between 2 and 3 mm when the lug 50 passes from one extreme position to the other, after rotation of the second element 20 relative to the first element. 10.

When the second element 20 is in the lower stop position corresponding to FIG. 2, with the lug 50 bearing against the left end 53 of the slot 51, the lower end 19 of the inner extension 14 may not not deform substantially the wall 45 of the wiper member 40 and the fins 48 can extend maximally towards the inside of the circular orifice 18 defined by the lower end of the introduction cone 15, as one can be seen in Figure 7. The spin is maximum and the product load on the minimum application element.

The rod 31 may advantageously have, as illustrated in FIG. 1, an annular narrowing 35 whose diameter corresponds substantially to that of the circle C passing through the vertices of the fins 48 in the configuration of FIG. 7. Thus, the rod 31 exerts no constraints or even exerts only relatively small constraints on the wiper member, which reduces the risk of permanent deformation thereof.

When the second member is rotated in the direction of the arrow R in Figure 2, the lug 50 moves in the slot 51 and rises relative to the first member 10. The inner extension 14 presses downwardly against the wall 45 and the fins 48 are spaced apart. The fins then extend over a smaller distance projecting inside the orifice 18, as can be seen in FIG. 8. At the end of the rotation stroke in the direction of the arrow R, the lug 50 reaches the high stop position corresponding to the half-section on the left in FIG. 1 and the fins 48 practically no longer project in the orifice 18, as can be seen in FIG. 9.

In the example considered, the inner extension 14 does not cross the transverse wall 45. In a variant (not shown), the axial displacement stroke of the inner extension 14 is sufficiently large for it to pass entirely through the wiper member 40.

Those skilled in the art can choose the degree of deformation of the wiper member depending on the desired result, for example according to whether or not it wishes to maintain a spin regardless of the position of the pin in the slot, or to be able, for a given position, to run only on the edge of the inner extension.

For example, one can have two positions respectively corresponding to a spin on the elastically deformable wiper member and a spin on the inner extension. It is also possible to have in a variant for a position at least one absence of spin, by performing the inner extension so that it can not normally wring the application element.

Preferably, the necking 35 extends over a height h which is greater than the maximum axial stroke d of the second element relative to the first element, so that whatever the position of the lug 50 in the slot 51, c 'is always the shrinkage 35 which comes opposite the end of the fins 48. In a variant (not shown), the rod is devoid of shrinkage.

To assemble the device 1, the wiper member 40 is for example fixed on the second element 20, then the latter is introduced into the first element. To facilitate the passage through the lug 50 of the lower portion 55 of the first element 10, the wall 11 of the latter may advantageously comprise a notch 56 on its radially inner surface, opening for example at the lower end 58 of the wall 11. , as shown in Figure 10.

The notch 56 may optionally have a ramp 85 which facilitates the passage of the lug, as shown in FIG. 11.

The lug 50 may have a rounded upper end 60, as shown in FIG. 12, in order to facilitate the crossing of this lower portion 55.

In the variant illustrated in FIG. 13, the lug comprises a chamfer 61.

The notch 56 can be positioned relative to the slot 51 so that the pin 50, after the X-axis displacement in the notch 56, reaches a position adjacent to the end 53.

The length of the lug allows it, for example, to protrude slightly out of the slot 51, as can be seen in FIG. 12. In this figure, a discontinuous line illustrates the possibility, in a variant, of the pin 50 to have a reduced length to stay set back from the outer surface of the second element.

The lug may optionally be colored so as to appear more clearly, and may in this case be made for example by bi-injection of material with the remainder of the second element 20.

The rod 31 is for example engaged in a sub-capsule 70 of the gripping member, this sub-capsule 70 may comprise a mounting skirt 71 internally threaded, arranged to be screwed onto an external thread 72 of the neck 12. The skirt mounting 71 can support an outer cover 73, for example metal.

The rod 31 may comprise, at its upper end, a series of grooves 75 allowing it to be pressed into the sub-capsule 70.

The latter can also comprise, as illustrated, a sealing lip 76 which is applied to the radially inner surface of the neck 12 at the end of the screwing of the sub-capsule 70 onto the neck 12. Of course, the gripping member could be fixed still further on the first element 10, for example by friction or snap.

In the embodiment of FIG. 1, the applicator element 100 is a brush comprising a twisted core 102 and projecting elements 103 constituted by bristles, extending from the core. The application element 100 in FIG. 14 is represented in more detail. The application element 100 defines an envelope surface E having at least one eccentric cross-section with respect to the core 102.

The envelope surface E extends along a longitudinal axis W making a non-zero angle α with a longitudinal axis Z of the core. With this configuration, the cross-section of the envelope surface E is eccentric to the core at least one point of the length of the applicator element, in this case at almost every point along the length of the applicator element. the application element 100.

To produce the applicator element, it is possible, for example, to start from a blank of cylindrical envelope of revolution about the axis Z of the core, the blank being rectilinear coaxial with the longitudinal axis X of the rod, then the blank is machined to give it the desired shape.

The application element 100 thus comprises bristles of different lengths. The longer hairs may for example always be dewatered regardless of the setting made by the user on the wiper member. The shortest hairs may for example still be not dewatered regardless of the setting made by the user on the wiper member, the remaining product thus stored between the shortest hairs. The bristles of intermediate length can be dewatered differently, depending on the setting made by the user on the wiper member.

By way of example, FIGS. 15 and 16 illustrate the application element 100 in the wiping orifice of the wiper member set in two different ways.

In the example of FIG. 15, the diameter of the wiper member is chosen so that it corresponds to the length of the longest protruding elements, so that the application element little or no wringing.

In the example of Figure 16, the diameter of the wiper member corresponds to the length of the shortest projecting elements, so that the application element is fully wrung out.

Thus, the user can choose at will the degree of product loading of the application 100 and / or the location of the most product-laden areas and the least loaded product areas on the application element 100.

For makeup, the user unscrews the applicator 30 and extracts the applicator element 100 from the container, the latter being wrung out as it passes through the wiper member 40.

Depending on the setting made by the user on the wiper member to adjust its inner section as desired, the application member 100 can be dewatered differently. The wringing can make it possible to create on the applicator element 100 areas that are weakly or not loaded with product, which may allow the combing of the eyelashes and / or eyebrows, and zones that are very heavily laden with product, which may allow the application product on the eyelashes or eyebrows.

These zones may be arranged differently or of different sizes depending on the setting made on the wiper member and the size or shape of the inner section chosen by the user.

Thus, with a single device, a single application element and a single wringing member, the user can make makeups producing different and varied effects.

Of course, it is possible to make various modifications to the applicator and in particular to the application element without departing from the scope of the present invention.

In the example illustrated in FIG. 14, the envelope surface E is of circular cross section.

Alternatively, the envelope surface E of the applicator element may have a cross section, at least one point of its length, which is non-circular, this cross section being for example polygonal, as can be seen in FIG. 17.

More particularly, in this example, the applicator element is of substantially triangular cross section, defining three longitudinal ridges 115 and three substantially planar faces 116 extending between the ridges.

The user can, if necessary, slightly rotate the application element on itself around the axis X of the rod. During makeup, the ridges 115 can act as a comb to separate the eyelashes may be stuck by an excess of product in some places. This combing effect can be facilitated especially when the circumferential dimension of the crests 115 is less than or equal to 2 mm for example. This can promote the combing and bending of the eyelashes by allowing better penetration of the bristles of the applicator element inside the eyelashes.

In particular, it is possible to give the applicator element various transverse sections, for example square as illustrated in FIG. 18, pentagonal or hexagonal, as represented respectively in FIGS. 19 and 20.

The application element may comprise at least one plane or concave face. The applicator element may, for example, comprise a circular cross-sectional envelope surface with at least one flat surface 128, as illustrated in FIG. 21, with at least one concave side 129 as illustrated in FIG. minus a convex side 130, as shown in FIG. 23. In this last figure, it can be seen that the applicator element may have an envelope surface of oblong, in particular lenticular, cross section.

The applicator element may have at least one convex face, of radius of curvature, when the applicator element is observed in cross-section, greater than the length of the longest hair extending from the core. .

The applicator element may also comprise an envelope surface of star-shaped cross section, as illustrated in FIG. 24, or else forming notches 134, for example three notches, as illustrated in FIG. 25, or four notches, as illustrated in FIG. FIG. 26, or forming lobes, for example four lobes, as shown in FIG. 27, or H-shaped, as illustrated in FIG. 28. The application element may also comprise an envelope surface E of section cross-section in the general shape of a keyhole, for example having on a major part of its circumference short bristles 135 and on the rest of its circumference bristles 136 of greater length, as illustrated in FIG. 29.

In the cross-sectional examples illustrated in FIGS. 17 to 29, the cross-section is shown centered with respect to the core. Alternatively, the core may also be eccentric with respect to the cross section of the envelope surface at at least one point of the brush, as shown in FIGS. 30 to 32. In FIG. 30, the cross section is of polygonal shape, square, rectangular in Figure 31 and oblong in Figure 32. Whatever its shape, the cross section may be centered or eccentric with respect to the soul.

In most of the cross-sectional examples illustrated in FIGS. 15 to 32, two examples of wiper member orifices are drawn in dashed lines. It is understood from the observation of the figures that when the wiper member is adjusted so that its inner section corresponds to the largest orifice G illustrated in the figures, the application element is less wrung than when the body of spin is adjusted so that its inner section corresponds to the smaller aperture P shown in the figures.

Since the cross section of the envelope surface of the applicator element is eccentric or non-circular, it comprises bristles of different lengths, the spin variation between the two different settings of the internal section of the body of the body. spin is different.

The longest hairs may for example always be dewatered, the shortest hairs may for example never be fully dewatered, while the hairs of intermediate length may for example be more or less dewatered depending on the setting chosen for the inner section of the wiper member.

Thus, the differences in spinning due to the setting of the wiper member are amplified by the shape of the applicator element.

In the illustrated examples, the spin port has been shown to be circular, but it could of course be of another shape, substantially circular or otherwise.

In the example illustrated in Figure 14, the envelope surface E is of constant circular cross section over most of the length of the applicator element, namely over its entire length.

Of course, it is not beyond the scope of the present invention when the envelope surface has at least one portion whose cross section varies, for example in a homothetic manner, for example decreasing in the direction of the free end of the element. application.

As a variant, the transverse section E of the envelope surface of the applicator element may pass through at least one extremum between its two axial ends, for example a maximum or a minimum, or both, as can be seen on Figure 33. In this figure, the cross section passes through a minimum 140 and two maximum 141, 142.

In another variant embodiment, the envelope surface of the applicator element may be unsymmetrical relative to a median plane perpendicular to the core, for example as illustrated in FIG. 34. In this exemplary embodiment, the application element is made from a blank on which facets 150 have been cut.

The longitudinal axis Z of the core of the applicator element may coincide with the longitudinal axis X of the device, or alternatively be distinct. By way of example, FIG. 35 illustrates an exemplary embodiment in which the core of the applicator element extends along an axis Z forming an angle δ with the axis X of the rod. The angle may for example be between 1 ° and 15 °.

In the embodiments which have just been described, the core of the application element is rectilinear, but it is not beyond the scope of the present invention if it is otherwise.

By way of example, FIGS. 36 to 38 illustrate three exemplary embodiments in which the core of the applicator element is curved. In the exemplary embodiment illustrated in FIG. 36, the application element is configured to comprise a plane face and a concave face. In the example of FIG. 37, the applicator element has a plane face 150 and a convex face, and in the example of FIG. 38, the applicator element has two plane faces 150.

In the exemplary embodiment illustrated in FIG. 39, the applicator element comprises a core 102 that curves over at least a part of its length and an envelope surface E that is not symmetrical with respect to a median plane perpendicular to the core. In addition, the angle between the axis X of the rod 31 and the axis of the core is at all points of the core less than 90 °. The free end of the applicator element is non-aligned with the X axis of the rod.

In another variant embodiment illustrated in FIG. 40, the applicator element is curved around at least two axes C ₁ , C _{2 which are} not parallel to one another. The axes C ₁ and C ₂ extend in directions that can be for example perpendicular.

In the exemplary embodiment illustrated in FIG. 36, the application element 100 comprises a free end 152 constituting the point of the application element furthest from a longitudinal axis X of the device.

In this exemplary embodiment, the core of the applicator element extends along a longitudinal axis Z on the same side of a plane containing a longitudinal axis X of the device.

In the variant embodiment illustrated in FIG. 41, the applicator element is made from a blank in which notches 155 have been cut.

The notches have an outwardly convex shape in cross-section, but it is within the scope of the present invention when the notches have a concave outward cross-sectional shape.

In the examples just described, the core consists of a twisted wire in which the bristles are held.

The strands of the soul can be twisted left or right.

It is particularly advantageous to use a left-handed brush, as will be explained with reference to Figs. 42 and 43.

In Figure 42, there is shown a brush with a twisted core on the left and in Figure 43 a twisted core on the right. We have schematized by dotted lines the path of nappes N defined by the ends of the bristles, these plies forming an angle β with a plane perpendicular to the core. We can usefully refer to the European patent EP 611 170 .

The soul can still be a double soul, formed by two elementary souls twisted together, as shown in Figure 44. Each elementary soul may comprise two strands twisted together and enclosing hairs. The two elementary cores can each be constituted by a branch of a single twisted core folded U-shaped, the two branches being twisted together.

Alternatively, the bristles can be fixed in orifices in the core of the applicator element.

In one application element made according to the invention, it is possible to use all kinds of bristles, and in particular bristles having a circular or other than circular cross section. In particular, it is possible to use a mixture of bristles of different natures or a mixture of bristles of different lengths, of the same nature or not.

It is particularly possible to use bristles having in cross-section one of the following forms: for example a circular shape with a flat, flattened, star-shaped, for example cross-shaped or three-pointed, U, H, T, of V, a hollow shape, for example circular or square forming branches, for example flake-shaped, a prismatic section, for example triangular or square or hexagonal or an oblong shape, in particular lenticular or hourglass-shaped. Hair with articulated parts may be used in relation to one another. It is also possible to use bristles having at least one capillary groove.

The bristles that are retained between the twisted strands of the core may have, before placement between the strands of the soul, a rectilinear shape or not, for example a wavy shape.

Hair may be treated to form balls or forks at their ends. It is possible to use flocked bristles or bristles made by extrusion of a plastic material comprising a charge of particles, for example particles of a moisture-absorbing material, in order to impart a micro-relief to the surface of the bristles, or give them magnetic or other properties. The bristles can still be made with a material having properties promoting sliding.

The bristles may be natural or synthetic and for example be made of a material selected from: PE, PA, in particular PA6, PA6 / 6, PA 6/10 or PA-6/12, HYTREL ^®, PEBAX ^®, silicone, PU, this list being non-limiting.

The invention is not limited to a particular type of application element and the application element is for example other than a mascara brush, being for example a comb as illustrated in FIGS. 45 to 47, a Flocked tip or not, for example elastomer, felt or foam, as shown in Figure 48. The application member may be of greater transverse dimension less than or greater than a diameter of the rod 31.

In the exemplary embodiments illustrated in FIGS. 45 to 47, the application element comprises teeth 160 made in one piece with the core. The teeth are for example made by molding, in particular by injection molding with the core, or by machining or stamping.

The envelope surface E of the comb is defined by the shape of its cross section.

In the embodiment illustrated in FIG. 45, the application element 100 comprises a single row of teeth 160 extending parallel to the longitudinal axis of the device.

Of course, it is not beyond the scope of the present invention when the application element comprises a different number of rows of teeth, for example at least two rows.

By way of example, FIG. 46 illustrates an exemplary embodiment in which the application element 100 comprises four rows of teeth 160, and in FIG. 47 an exemplary embodiment in which the application element 100 has three rows of teeth 160.

In these last two embodiments, at least two teeth each extend in different directions A, B from the core, these two directions A, B forming between them an angle y, for example substantially equal to 90 ° .

In the embodiment of Figure 46, at least one of the rows of teeth extends substantially in the extension of at least one face of the core.

The core 102 of the application element may have a shape cross-section selected from the following list: oval, oblong, elliptical, lenticular, circular, polygonal, triangular as shown in Figure 47, square as shown in Figure 46, pentagonal, hexagonal or octagonal.

In general, the applicator element may be chosen from the application elements defining an envelope surface having at least one eccentric cross-section with respect to the core and / or non-circular, and described in the patents or following patent, the contents of which are incorporated by reference:

US 6,581,610 , US 6,412,496 , US 6,539,950 , US 6,343,607 , US 09/860 601 , US 6,866,046 , US 6,814,084 , US 6,675,814 , US 6,446,637 , US 6,546,937 , US 6,655,390 , US 6,662,810 , US 2002/0124860 , US 2002/0139385 , US 2003-0089379 , US 2003-0178043 , US 2003-0213498 , US 2004-0134507 , US 2004-0226573 and US 2004-0240926 .

The wiper member 40 may also be made differently, comprising, for example, a fixed membrane which can be deformed by the longitudinal displacement of a rigid hollow element, as illustrated in FIG. 49. The element 10 may be rotated relative to to the container 20. The two elements 10 and 20 can cooperate by means of at least one helical relief for example, the displacement in rotation causing a translation displacement of one element relative to the other.

The wiper member may also be made differently and in particular not work in elongation but in compression, as shown in Figures 50 and 51.

In these figures, there is partially shown a device whose lower part not apparent is for example the same as that of the device of Figures 1 and 2 and whose upper part has been modified to accommodate the wiper member 40, made of an elastically deformable material.

The wiper member 40 rests on its lower face 91 against a shoulder 92 formed for example by an annular rib 93 of the body 21 and bears on its upper face 94 against the lower edge 95 of an inner extension of the first element 10.

When the second element 20 is in the least engaged configuration in the first element 10, the wiper member 40 is only slightly or weakly compressed, so that it provides a relatively large aperture 96, which is for example of a first diameter D ₁ .

Alternatively, the compression of the wiper member may be obtained otherwise, for example by a displacement in translation of the control member relative to the container.

When the second element 20 is angularly displaced relative to the first element 10 so as to further engage in this first element 10, the wiper member 40 is further compressed between the first element 10 and the second element 20 and the diameter of the first element 10. the opening 96 is reduced and passes to a second diameter D ₂ less than D ₁ .

If necessary, the wiper member 40 can be applied sealingly to the rod 31 when the diameter of the opening 96 is reduced, as illustrated in FIG. 52.

The wiper member may be further replaced by a flow reducer.

The wiper member can also be made at least partially monolithically with one of the first and second elements, as illustrated in FIG. 53.

The first element 10 is made in this example with an inner extension terminated by a plurality of flexible tabs 170, which are engaged in the second element and can abut against a surface 171 thereof. This surface 171 is for example conical, converging towards the bottom of the container.

The free ends of the tongues define an opening for the passage of the application element, the user can vary the diameter by changing the axial positioning of the first element relative to the second.

When the inner extension of the first element sinks into the second element, these tongues are deflected radially inwards, which decreases the diameter of the wringing orifice.

When the first element rises, the tabs tend to move apart due to their own elasticity, and the diameter of the wiper orifice increases.

When the tongues are sufficiently raised, the diameter of the wiping orifice can be defined by the radially inner edge of the surface 171.

The wiper member may alternatively be arranged to deform in shear, the adjusting member being for example configured to rotate a first end 181 of the wiper member 40 relative to a second end 182 of the wiper member 40, as illustrated in FIG. it is deformable so that its inner section is reduced.

The adjustment member may alternatively come transversely bearing on the wiper member. By way of example, FIG. 55 illustrates a device comprising a button 185 adapted to be driven in translation by the user in a direction D perpendicular to a longitudinal axis X of the device. The movement of the button 185 causes the reduction of the inner section of the wiper member 40.

The button 185 may be associated with a return member 186, for example a spring, configured to return the button 185 to its initial position corresponding to a larger inner section of the wiper member.

The invention is not limited to the examples of implementations which have just been described.

The characteristics of the different embodiments described can in particular be combined with each other within non-illustrated examples.

The wiper member may be realized in a different manner, in particular in the manner described in FR 2 515 941 for example.

1. i) on effectue un premier réglage de la section intérieure de l'organe d'essorage,
2. ii) on retire l'élément d'application du récipient pour appliquer le produit, notamment sur les cils ou les sourcils,
3. iii) on effectue un second réglage de la section intérieure de l'organe d'essorage, différent du premier réglage,
4. iv) on retire l'élément d'application du récipient.

The subject of the invention is also a process for applying a product, in particular a cosmetic product, for example mascara, by means of any one of the devices which have just been described, comprising the following steps:

1. i) a first adjustment of the inner section of the wiper member is carried out,
2. ii) removing the applicator element from the container to apply the product, in particular to the eyelashes or the eyebrows,
3. iii) a second adjustment of the inner section of the wiper member, different from the first setting,
4. iv) removing the applicator element from the container.

In the second setting, the inner section of the wiper member may be smaller, so that the spin is stronger.

Thus, after step iv), it is possible to comb the eyelashes or eyebrows with a more wrung application element.

The expression "having one" shall be understood as being synonymous with "having at least one", unless the opposite is specified.
