PROCESS FOR APPLYING A COSMETIC COMPOSITION COMPRISING A ROTARY APPLICATOR

Abstract

The invention relates to a process for applying a coating composition on keratin fibers, comprising the following steps: a) application of a base composition on the keratin fibers; then b) application of a coating composition of the base composition on the keratin fibers, the application of the coating composition comprising the driving in rotation of an application member with respect to a gripping member, by displacing the application member on said keratin fibers, the application member being impregnated with said coating composition of the base composition.

Description

This invention has for object a process for applying compositions on keratin fibers.

Conventional make-up compositions for the eyes, also called “mascaras” for eyelashes, usually have a pasty texture and are packaged in a receptacle comprising a reservoir provided with a squeezing device and an application member, in particular in the form of a brush or a comb, and are applied by sampling the product in the reservoir using the application member, passing of the application member through the squeezing device in order to remove the excess product, then putting the application member impregnated with mascara in contact with the eyelashes.

It is generally through their formulation, and in particular the qualitative and quantitative choice of the waxes and optional polymers, that the sought properties for the mascaras are adjusted, such as for example their fluidity, their lengthening power and/or their curling power. Thus, it is possible to carry out various compositions that, applied in particular on the eyelashes, induce varied effects of the lengthening, curling and/or thickening (loading effect) type of the eyelashes.

With the makeup compositions currently available, these effects are generally obtained by overlaying several layers of makeup composition on the eyelashes.

However, certain effects, such as for example particular color effects, cannot be achieved with a conventional mascara for the effective accumulation of several layers of mascara, in particular of different compositions.

There is therefore a need for compositions that, when they are applied on the eyelashes with the suitable application member, make it possible to effectively accumulate layers, while keeping intact the first layer (i.e. without pulling it off or damaging it), or mixing the layers together. There is furthermore a need for a makeup process for eyelashes that makes it possible to obtain particular, in particular color, effects. Such effects are in particular an overlaying of mascaras of two different colors without mixing them, or a deposit of a coating layer discontinuously on a first layer, in order to view said first layer.

The inventors discovered that the properties described hereinabove can be obtained by using a process comprising firstly the application of a composition with a keratin fiber base; then the application of a coating composition of the composition with a keratin fiber base, the application of the coating composition comprising the driving in rotation of an application member with respect to a gripping member, by displacing the application member on said keratin fibers, the application member being impregnated with said coating composition of the base composition.

Indeed, the application of the aforementioned coating composition with an application member in free rotation with respect to the gripping member, makes it possible to deposit successive layers, without the need of waiting for the first layer (i.e. of the base composition) to be dry. This accumulation of layers makes it possible to obtain effects that are not achieved with the conventional application of several layers of products and this in a practical manner, by successively applying, without waiting time, the base composition layer and the coating composition layer.

Furthermore, the application of the aforementioned coating composition with an application member in free rotation with respect to the gripping member, makes it possible to keep the first layer intact. A multi-layer deposit without mixing different layers together is as such obtained.

More precisely, the invention has for object a process for applying a coating composition on keratin fibers, comprising the following steps:

a) application of a base composition on the keratin fibers; then

b) application of a coating composition of the base composition on the keratin fibers, the application of the coating composition comprising the driving in rotation of an application member with respect to a gripping member, by displacing the application member on said keratin fibers, the application member being impregnated with said coating composition of the base composition.

A requisite for application according to the invention comprises a system for applying able to apply a base composition on keratin fibers, and a device 10 for packaging and applying a coating composition of the base composition on keratin fibers.

Said system for applying typically comprises a receptacle intended to contain the base composition, and an applicator. The system for applying is for example identical to the device 10 described in what follows.

The base composition shall be described following the description of the requisite for application.

A first embodiment of the device 10 for packaging and applying a coating composition of the base composition is shown in FIGS. 1 to 9.

The device 10 comprises a receptacle 12 intended to contain the coating composition of the base composition, and an applicator 14 removably mounted on the receptacle 12 and able to apply the coating composition of the base composition.

The keratin fibers are typically eyelashes. The coating composition of the base composition is then a coating composition of eyelashes. This coating composition of eyelashes shall be described following the description of the requisite for application.

The device 10 advantageously has a generally cylindrical shape extending along a longitudinal axis A. The terms “longitudinal” and “radial” generally mean in relation to the longitudinal axis A.

In reference to FIG. 1, the receptacle 12 comprises a hollow body 26, able to contain the coating composition, and a threaded neck 30 protruding outwards from the body 26 by defining an access opening 28 for the product.

The receptacle 12 also comprises a squeezing device 32 inserted into the neck 30.

The applicator 14 comprises a gripping member 16, extending along the longitudinal axis A, a rod carrier 18, arranged in the gripping member 16 and mounted freely mobile in rotation about the longitudinal axis A with respect to the gripping member 16.

The applicator 14 also comprises a blocking device 19 that opposes the translation along the axis A of the rod carrier 18 with respect to the gripping member 16, a rod 20 integral with the rod carrier 18, a system for the selective blocking in rotation 24 of the rod carrier 18 with respect to the gripping member 16, and a first application member 22A of the coating composition (FIGS. 8 and 9) carried by the rod 20.

The applicator 14 is mounted mobile between an idle position, wherein is mounted on the recipient 12, the rod 20 and the first application member 22A being engaged at least partially in the receptacle 12, and a usage position, in which the rod 20 and the first application member 22A are extracted outside of the receptacle 12.

In the idle position, the applicator 14 is maintained fixed on the receptacle 12 for example by screwing on the neck 30.

The gripping member 16 comprises a cover 34 and a plug 36, with the plug 36 here added on the cover 34.

The cover 34 has a shape of revolution about the longitudinal axis A. It is for example cylindrical.

The cover 34 comprises a peripheral wall 38 about the longitudinal axis A. It extends between a distal edge 40 intended to be placed facing the receptacle 12 in an idle position of the applicator 14, and a proximal edge 42 intended to be placed apart from the receptacle 12 in the idle position of the applicator 14.

The cover 34 is hollow, and defines an inner surface 44 that delimits an inner volume 46.

In the vicinity of the proximal edge 42 of the cover 34, the inner surface 44 of the cover 34 has a circumferential shoulder 50 of the bearing of the plug 36, shown in FIG. 2, and a protrusion 52 for maintaining the plug 36 in position against the shoulder 50.

In reference to FIGS. 3 and 4, the cover 34 comprises a transverse wall 54, that extends radially from the inner surface 44 of the cover 34.

The transverse wall 54 is arranged longitudinally apart from the proximal edge 42. It defines a plurality of radial slots 56.

The radial slots 56 delimit between them at least two contact tongues 58. The gripping member 16 here comprises three contact tongues 58.

Each tongue 58 radially protrudes from the peripheral wall 38, and more precisely, from the inner surface 44 of the cover 34.

Each tongue 58 defines a free inside edge 60, directed towards the longitudinal axis A. The free edge 60 has an inner chamfer that converges towards the axis A in the direction away from the rod 20 to the plug 36.

In FIG. 2, the plug 36 is securely fastened to the cover 34. It closes the cover 34 on its proximal edge 42.

The plug 36 comprises a sealing wall 62, a peripheral ring 64 for mounting in the cover 34 and an inner sleeve 66 for guiding the rod carrier 18.

The peripheral ring 64 protrudes from the periphery of a distal face 70 of the sealing wall 62.

The peripheral ring 64 comprises at least one attaching stop 72, for example four attaching stops 72 distributed angularly about the longitudinal axis A.

The peripheral ring 64 is arranged in abutment against the shoulder 50 of the cover 34. Each attaching stop 72 cooperates with the protrusion 52, in order to removably immobilize the plug 36 with respect to the cover 34 and provide an aesthetic aspect.

A proximal face 68 of the sealing wall 62 is flush with the proximal edge 42 of the cover 34.

The inner sleeve 66 protrudes longitudinally in the cover 34 from the distal face 70 of the sealing wall 62.

The inner sleeve 66 delimits an internal cavity 74 and a bulge 76 that protrudes radially towards the longitudinal axis A in the internal cavity 74.

The inner sleeve 66 is for example made of acrylonitrile butadiene styrene (ABS), polyoxymethylene (POM), polyethylene (PE), or polypropylene (PP).

The rod carrier 18 is for example made from polybutylene terephthalate (PBT), polyoxymethylene (POM) or polypropylene (PP).

The rod carrier 18 comprises a longitudinal guiding segment 78, extending between a proximal end 80 and a distal end 82, and a head 84 for mounting on the receptacle 12.

The longitudinal segment 78 extends in the internal volume 46 along the longitudinal axis A. The proximal end 80 is received in the internal cavity 74 defined by the inner sleeve 66.

The rod carrier 18 as such has, on the bulge 76, a first linear contact region 86 with the gripping member 16. The first linear contact region 86 is a circumferential linear contact region about the longitudinal axis A.

In the example shown, the bulge 76 is continuous in the circumferential direction. The first linear contact region 86 of the rod carrier 18 is as such also continuous in the circumferential direction. Alternatively, the bulge 76 and/or the rod carrier in the first linear contact region is (are) discontinuous in the circumferential direction. The first linear contact region 86 of the rod carrier 18 is as such advantageously discontinuous in the circumferential direction.

The longitudinal segment 78 has, on the first contact region 86, a maximum diameter D1. The maximum diameter D1 is, advantageously between 1.5 mm and 5 mm, in particular between 2.0 mm and 3 mm.

The longitudinal segment 78 also defines a circumferential groove 88 about the longitudinal axis A opening radially opposite the longitudinal axis A.

As can be seen in FIG. 3, the longitudinal segment 78 comprises, at its distal end 82, a flared portion 89A that has an outer chamfer 89B. The circumferential groove 88 is defined in the flared portion 89A of the longitudinal segment 78, between the outer chamfer 89B and the head for mounting 84.

The circumferential groove 88 receives the free edge 60 of each contact tongue 58 of the gripping member 16.

The contact tongues 58 facilitate the assembly of the rod carrier 18 with the gripping member 16, via their snap-fitting into the circumferential groove 88. This assembly is easily obtained by relative translation along the axis A of the gripping member 16 with respect to the rod carrier 18, generating an axial deformation of the contact tongues 56. The cooperation between the inner chamfer on the free end 60 of each contact tongue 58 and the outer chamfer 89B facilitates the snap-fitting.

The longitudinal extend of the groove 88, taken along the axis A, is greater than the longitudinal extent of the free edge 60, taken along the same axis A by at least 10%.

As such, the rod carrier 18 has, on the free edge 60 of each contact tongue 58, a second linear contact region 90 with the gripping member 16. The second linear contact region 90 is a circumferential linear contact region.

In the example shown, the contact tongues 58 are discontinuous in the circumferential direction by being separated from each other by the slots 56. The second linear contact region 90 of the rod carrier 18 is as such also continuous in the circumferential direction. Alternatively, the rod carrier 18 has a contact tongue 58 that is continuous in the circumferential direction forming a continuous annular flange, made of a flexible material in order to allow for the snap-fitting of the rod carrier or associated with a washer for blocking in translation along the axis A integral with the rod carrier 18. Those skilled in the art will be able to determine the material to be chosen for the contact tongue 58 in order to have sufficient flexibility to allow for the snap-fitting of the rod carrier 18, according to the material chosen for the latter. The second linear contact region 90 of the rod carrier 18 is as such also continuous in the circumferential direction.

The first linear contact region 86 and the second linear contact region 90 are separated by a minimum distance I. The minimum distance I is, for example, greater than 20 mm and is preferably between 23 mm and 60 mm.

The minimum distance I is greater than or equal to two times the average diameter between the diameter D1 of the rod carrier 18 in the first linear contact region 86 and the diameter of the rod carrier 18 in the second linear contact region 90.

The first linear contact region 86 has a contact length 11 taken along the longitudinal axis A less than 5%, preferably less than 2% of the minimum distance I separating along the axis A the first linear contact region 86 and the second linear contact region 90.

Advantageously, the contact length 11 is less than 5%, preferably less than 2% of the diameter D1 of the longitudinal segment 78 taken on the first contact region 86.

The contact length 11 is as such less than 1 mm, and preferably between 0.05 mm and 0.5 mm.

Likewise, the second linear contact region 90 has a contact length 12 taken along the longitudinal axis A less than 5%, preferably less than 2% of the minimum distance I separating along the axis A the first linear contact region 86 and the second linear contact region 90.

On the second contact region 90, the circumferential groove 88 has a maximum diameter D2. The maximum diameter D2 is, for example, between 5.50 mm and 6 mm.

Advantageously, the contact length 12 is less than 5%, preferably less than 2% of the maximum diameter D2 of the circumferential groove 88 taken on the second contact region 90.

The contact length 12 is as such less than 1 mm, and preferably between 0.05 mm and 0.5 mm.

Advantageously, the contact regions 86, 90 are adapted so that, when a mechanical stress, resulting in a motion with respect to the longitudinal axis A, is applied on the first application member 22A, a rotation of the rod 20 and of the rod carrier 18 with respect to the gripping member 16 is obtained as soon as the motion crosses a limit value.

The longitudinal segment 78 has an intermediate region 92, shown in FIG. 1, defined between the first linear contact region 86 and the second linear contact region 90.

In the intermediate region 92, the rod carrier 18 is arranged entirely separated from the gripping member 16. More particularly, in the intermediate region 92, the rod carrier 18 and the gripping member 16 define a radial gap, measured perpendicularly to the longitudinal axis A, at least equal to 5%, preferably at least equal to 10%, and more preferably at least equal to 50% of the maximum thickness presented by the rod carrier 18, over at least 50% of the length of the intermediate region 92 taken along the longitudinal axis A.

The rod carrier 18 and the gripping member 16 have a functional radial gap between them in the first circumferential linear contact region 86 and/or in the second circumferential linear contact region 90.

Preferably, this functional radial gap is less than 0.5 mm, and more preferably less than 0.2 mm and in particular in the neighborhood of 0.1 mm. As such, when the rod carrier 18 and the gripping member 16 are placed coaxially to one another, such as shown in FIGS. 1 to 3, a gap in the radial direction exists on either side of the rod carrier 18, between the rod carrier 18 and the gripping member 16, in the first circumferential linear contact region 86 and/or in the second circumferential linear contact region 90, with this gap substantially corresponding to half of the aforementioned functional radial gap.

Advantageously, in the intermediate region 92, the rod carrier 18 and the gripping member 16 define a radial gap, i.e. a gap in the radial direction, greater than or equal to 1.1 times, preferably 1.5 times, the functional radial gap defined between the rod carrier 18 and the gripping member 16 in the first circumferential linear contact region 86 and/or in the second circumferential linear contact region 90, over at least 50% of the length of the intermediate region 92 taken along the longitudinal axis A. The term “radial gap” in the intermediate region 92 between the rod carrier 18 and the gripping member 16 here means the distance in the radial direction that separates the rod carrier 18 and the gripping member 16 on the intermediate region 92, when these two elements are arranged coaxially. As such, if the functional radial gap between the rod carrier 18 and the gripping member 16 in the first circumferential linear contact region 86 and/or in the second circumferential linear contact region 90 is for example 0.1 mm, then the radial gap between the rod carrier 18 and the gripping member 16 in the intermediate region 92, on one side and the other of the longitudinal axis A when the rod carrier 18 and the gripping member 16 are arranged coaxially, is greater than or equal to 0.11 mm, and preferably greater than or equal to 0.15 mm.

In reference to FIG. 3, the head for mounting 84 of the rod carrier 18 comprises a central ring 93 for fastening the rod 20 and a connecting skirt 94 protruding around the central ring 93. The connecting skirt 94 extends to the distal edge 40 of the cover 34, from the distal end 82 of the longitudinal segment 78.

The inner surface 96 of the connecting ring 94 is threaded, and is able to cooperate with the threading present on the neck 30 of the receptacle 12.

The connecting skirt 94 also comprises a longitudinal protrusion 100, that can be seen in FIG. 5, able to cooperate with a stop 102 of the receptacle 12, which can be seen in FIG. 3, in order to ensure the blocking in rotation of the rod carrier 18 with respect to the receptacle 12 in idle position.

The ring 94 and the longitudinal segment 78 define a central housing 104. In the example of FIG. 3, the central housing 104 extends to the proximal end 80 of the rod carrier 18 until a bottom 106, arranged longitudinally beyond the circumferential groove 88 of the longitudinal segment 78.

The blocking device 19 is configured to limit the relative translation along the axis A of the rod carrier with respect to the gripping member to a functional gap between these elements. This functional gap is preferably less than 2 mm, in particular less than 1 mm and in particular in the neighborhood of 0.7 mm, even in the neighborhood of 0.5 mm.

The blocking device 19 comprises a first axial stop surface 108A formed on the rod carrier 18, and a second axial stop surface 1088 formed by the gripping member 16.

Preferably, the first and second axial stop surfaces 108A, 1088 are adjacent along the axis A at one at least of the first and second contact regions 86, 90.

In the example in FIG. 3, they are adjacent to the second contact region 90. The first axial stop surface 108A is as such formed by a shoulder defined in the flared portion 89A by the circumferential groove 88, and the second stop surface 108B is formed by a proximal surface of the transverse wall 54 of the cover 34, on the free edge 60.

The rod 20 is added in the central housing 104.

The system for the selective blocking in rotation 24 of the rod carrier 18 with respect to the gripping member 16 is shown in FIGS. 5 to 7.

The blocking system 24 can be maneuvered between an inactive configuration, in which the rod carrier 18 is freely rotating about the longitudinal axis A, and an active configuration, in which the rod carrier 18 is entirely blocked in rotation with respect to the gripping member 16. The term total blocking here means a “frank” contact of elements abutting against one another, and not only a friction contact.

The blocking system 24 comprises splines 112 formed on the rod carrier 18, and at least one flexible tab 114 able to cooperate with the splines 112. It comprises, for each flexible tab 114, a flexible hinge 116 for connecting the flexible tab 114 to the cover 34 of the gripping member 16.

The or each flexible tab 114, the flexible hinge 116 and the cover 34 are advantageously from the same material.

The splines 112, which can be seen in FIG. 5, are arranged on an external peripheral surface of the rod carrier 18. In particular, the splines 112 are arranged on an outer surface 98 of the connecting ring 94 of the rod carrier 18.

In the example of FIGS. 6 and 7, the blocking system 24 comprises two flexible tabs 114 diametrically opposite with respect to the axis A.

Each flexible tab 114 is mounted mobile on the gripping member 16.

It is defined by a cut made through the gripping member 16. The cut is here of a rounded shape, for example in the shape of a C.

Each flexible tab 114 comprises at least one locking cog 118 radially protruding towards the axis A. The locking cog 118 is able to be inserted into a spline 112 in the active configuration of blocking, in order to block the rod carrier 18 in rotation with respect to the gripping member 16. It is arranged entirely apart from the splines 112 in the deactivated configuration.

The first application member 22A is also designated by the term “brush” in what follows. Preferably, the first application member 22A is made of elastomer.

The first application member 22A is fixed to the free end of the rod 20.

It is able to be driven in rotation by keratin fibers, in particular about the longitudinal axis A, with respect to the gripping member 16.

As shown in FIGS. 8 and 9, the first application member 22A comprises a support body 120 and a plurality of pins 122 formed on an outer surface 124 of the support body 120, the pins 122 being formed on the outer surface 124 in the form of rows.

The first application member 22A advantageously has an axial symmetry along the longitudinal axis A.

The first application member 22A comprises an even number of rows of pins.

The number of rows of pins is here equal to 12. Alternatively, the number of rows of pins is greater than or equal to 8, and advantageously between 8 and 16.

The support body 120 has a substantially circular section transversal to the longitudinal axis A.

The transversal section of the support body 120 has a diameter between 1.5 mm and 4 mm.

The support body 120 is made of elastomer. Alternatively, the support body 120 is for example made of hytrel, SEBS or polypropylene (PP).

Each pin 122 has a substantially conical shape of revolution.

On the outer surface 124 of the support body 120, each pin 122 has a section with a diameter between 0.1 mm and 1 mm.

The pins 122 of the same row have the same section taken on the outer surface 124 of the support body 120. More generally, all of the pins 122 of the first application member 22A have the same section taken on the outer surface 124 of the support body 120.

Each pin 122 has a height greater than 2 mm, advantageously between 1.5 mm and 5 mm.

The pins 122 of the same row have an identical height. More generally, all of the pins 122 of the first application member 22A have an identical height.

Each pin 122 extends from the outer surface 124 along a predetermined direction perpendicular to the longitudinal axis A. The predetermined direction of a pin is a straight line passing through the middle of any section of said pin parallel to the longitudinal axis A.

The pins 122 of the same row have predetermined parallel directions.

Each pin 122 is as a single piece with the support body 120, each pin 122 is then made of elastomer. Alternatively at least one portion of the pins 122 is made from a material different from that of the support body 120 by overmolding on the support body 120.

Each row of pins extends parallel to the longitudinal axis A.

Each row of pins has a length greater than 2 mm.

Each row of pins comprises a number of pins 122 greater than 20 and advantageously between 30 and 50.

The difference between two adjacent pins of the same row is identical for all of the pins of said row. Two pins of the same row are considered to be adjacent if no pin of said row is arranged between these two pins.

The difference between two adjacent pins of the same row is between 1% and 10% of the height of the pins 122.

The difference between two adjacent pins of the same row is identical for all of the rows of the first application member 22A.

A first row 126 of pins is arranged adjacent to a second row 128 of pins, and a third row 130 of pins is arranged adjacent to the second row 128 of pins. Two rows of pins are considered to be adjacent if no row of pins is arranged between these two rows.

As shown in FIG. 8, preferably, the second row 128 of pins comprises one pin 122 less than the first row 126 of pins. The first row 126 of pins and the third row 130 of pins comprise the same number of pins 122. They comprise here 21 pins.

More generally, two rows of the first application member 22A separated by a single row of pins comprise the same number of pins 122.

In particular, the second row 128 comprises a number of pins equal to the number of pins 122 of the rows adjacent to the first row 126 and to the third row 130. These rows here comprise 20 pins.

Preferably, according to a first embodiment, at least one pin of the second row 128 is arranged axially along the longitudinal axis A between two adjacent pins of the first row 126.

In particular, all of the pins 122 of the first row 126 are axially offset along the longitudinal axis A relative to the pins 122 of the second row 128 by a predetermined distance taken on the outer surface 124 of the support body 120.

The predetermined distance is greater than 1% of the height of the pins 122.

In the example shown in FIG. 8, each pin of the second row 128 is located midway axially along the longitudinal axis A of two adjacent pins 122 of the first row 126.

In other terms, the predetermined distance is substantially equal to half the sum of the diameter of a pin and of the difference between two adjacent pins 122, said difference and said diameter being taken on the outer surface 124 of the support body 120.

The predetermined directions of the pins 122 of the second row 128 are contained in the angular sector defined by the predetermined directions of the pins 122 of the first row 126 and the predetermined directions of the pins 122 of the third row 130.

Each pin 122 of the first row 126 is axially positioned, along the longitudinal axis A, at the same position as a pin of the third row 130. In other terms, the third row 130 is not axially offset with respect to the first row 126.

More generally, two rows of the first application member 22A separated by a single row of pins 122 are not axially offset with respect to one another.

In particular, each pin of the second row 128 is as such axially positioned, along the longitudinal axis A, at the same position as a pin of the rows adjacent to the first row 126 and to the third row 130.

The distance, taken on the outer surface 124, between a pin of the first row 126 and at least one pin of the third row 130 is less than 30% of the height of the pins 122.

As shown in FIG. 9, the distance between a pin of the first row 126 and the pin of the third row 130 axially positioned at the same position is less than the diameter of the section of the pins 122, said distance and said section being taken on the outer surface 124.

In projection in a plane perpendicular to the longitudinal axis (A), each pin of the second row 128 of pins is arranged between pins of the first row 126 and pins on the third row 130, preferably in the middle of the pins of the first row 126 and pins of the third row 130.

More precisely, in projection in a plane perpendicular to the longitudinal axis A, the predetermined direction of each pin of the second row 128 is the bisector of the angle formed between the predetermined direction of a pin of the first row 126 and the predetermined direction of a pin of the third row 130.

In other words, each pin of the second row 128 is arranged staggered with two adjacent pins of the first row 126 and two adjacent pin of the third row 130.

More generally, each pin of a row that has one pin less than its adjacent rows, is arranged staggered with two adjacent pins of one of its rows and two adjacent pins of the other of its adjacent rows.

Even more generally, even if the structure of the rod carrier 18 is different from that shown in the figures, the rod carrier 18 has at least two linear contact regions with the gripping member providing a free rotation and guided with respect to the gripping member.

Protocol for Measuring the Dry Matter or Dry Extract Content

The quantity of dry extract of a composition according to the invention is measured using a commercial halogen dessicator “HALOGEN MOISTURE ANALYZER HR 73” from METTLER TOLEDO. The measurement is taken based on the loss of weight of a sample dried by halogen heating and therefore represents the percentage of residual material once the water and volatile materials have evaporated.

This technique is described perfectly in the documentation of the device supplied by METTLER TOLEDO.

The measurement protocol is as follows:

About 2 g of the composition, hereinafter the sample, are spread over a metal cup which is inserted into the halogen dessicator mentioned hereinabove. The sample is then subjected to a temperature of 105° C. until a constant weight is obtained. The Wet Mass of the sample, corresponding to its initial mass, and the Dry Mass of the sample, corresponding to its mass after halogen heating, are measured using a precision balance.

The experimental error linked to the measurement is about plus or minus 2%.

The Dry Extract content is calculated in the following way:

Dry Extract content (expressed as a % by weight)=100×(Dry Mass/Wet Mass).

Method of Application

A process for applying compositions on keratin fibers of a user, according to the invention, using the requisite for application comprising the device 10 shall now be described.

Initially, the system for applying able to apply a base composition and the base composition are provided. Furthermore, a device 10 is provided with the applicator 14 in idle position, mounted and immobilized on the receptacle 12, the receptacle 12 containing the coating composition of the base composition.

The base composition is first of all applied onto the keratin fibers, in particular by the system for applying; this is the step a).

Then the step b) is carried out; the first application member 22A is impregnated with the coating composition.

In order to release the applicator 14 from the receptacle 12, the user blocks the rod carrier 18 in rotation with respect to the gripping member 16 by passing the blocking system 24 from its inactive configuration to its active configuration.

For this, the user exerts a radial pressure towards the axis A on each flexible tab 114. Each locking cog 118 is as such inserted into a spline 112, blocking in rotation about the axis A the rod carrier 18 with respect to the gripping member 16.

Simultaneously, the user releases the head for mounting 84 from the neck 30 here by unscrewing the unit formed by the gripping member 16 and the rod carrier 18, and by maintaining the blocking system 24 active. Then, the user extracts the rod carrier 18 and the first application member 22A outside of the receptacle 12 through the opening 28. The squeezing device 32 removes from the first application member 22A, the excess product that accompanies the exit thereof from the receptacle 12.

The user brings the first application member 22A of the coating composition in contact with the keratin fibers on which the base composition has already been applied.

The user displaces the first application member 22A on the keratin fibers. During this displacement, the mechanical stress of the keratin fibers on the first application member 22A drives in rotation the first application member 22A, the rod 20, and the rod carrier 18 with respect to the gripping member 16.

The displacement is accompanied by the depositing of the coating composition on the keratin fibers. The very low contact between the rod carrier 18 and the application member 16 on the regions 86, 90, decreases the friction between the rod carrier 18 and the gripping member 16.

The friction with the keratin fibers, which are applied on the first application member 22A during the application of the coating composition, very easily cause the rod 20 to rotate with respect to the gripping member 16.

As such the first application member 22A, instead of rubbing against the keratin fibers and removing a portion of the base composition that has already been deposited, rolls on the keratin fibers and does not remove any of the already deposited base composition. The force exerted by the user to roll the first application member 22A on the keratin fibers is minimized thanks to the pivot connection with reduced statically indeterminate created by the linear contact regions 86, 90.

Through the weakness of the shearing forces generated during the application of the coating composition on the base composition by the applicator 14, the base composition and the coating composition are superimposed without mixing together.

Furthermore, the step of displacing the first application member 22A on the keratin fibers does not require waiting for the drying of the base composition already applied on the keratin fibers.

As an alternative of the first application member 22A of the device 10, a second application member 22B is shown in FIG. 10.

This second application member 22B differs from the first application member 22A in that the pins of the second row 128 are not arranged staggered with the adjacent pins of the first row 126 and the adjacent pins of the third row 130.

Each row of pins has at least one pin 122 axially positioned, along the longitudinal axis A, at the same position as a pin 122 of each one of the other rows of pins.

In the example of FIG. 10, each pin 122 of the second row 128 is axially positioned, along the longitudinal axis A, at the same position as a pin of the first row 126 and of the third row 130. More generally, each pin 122 of at least one row of pins is axially positioned, along the longitudinal axis A, at the same position as a pin of each one of the other rows of pins.

Each pin 122 of a row that has one pin less that its adjacent rows, is axially positioned, along the longitudinal axis A, at the same position as a pin of each one of its adjacent rows.

Alternatively, the user can selectively block the rotation of the rod carrier 18 with respect to the gripping member 16 at any time, in particular during the application of the product.

Alternatively, the blocking device 19 is configured to authorize a relative translation travel along the axis A of the rod carrier 18 with respect to the gripping member 16, for example a travel less than 10 mm, in particular between 4 mm and 6 mm.

A damping elastic element (not shown) is for example arranged between the rod carrier 18 and the gripping member 16. This elastic element is arranged in such a way that the relative translation along the axis A is carried out, at least in one direction of translation of the rod carrier 18 with respect to the gripping member 16, against an elastic force exerted by the elastic element.

Alternatively, and according to an advantageous arrangement, the blocking system 24 comprises a deformable seal added in the cut around each flexible tab 114, in order to seal the cut at the periphery of each flexible tag 114. Such a seal makes it possible to prevent the insertion of dust into the internal volume 46 of the cover 34.

Alternatively, and according to an advantageous arrangement, the applicator 14 is able to be removably mounted onto the receptacle 12 by means of a snap-fitting or magnetism system, or by any other system that does not require a relative rotation of the applicator 14 with respect to the receptacle 12 in order to separate these two elements.

During the process of application of the coating composition, the user releases the applicator 14 from the receptacle 12, by pulling on the applicator 14 which is separated from the receptacle 12 via simple translation along the axis A.

The examples hereinafter are given by way of illustration and are not intended to limit the invention. Unless mentioned otherwise, the quantities indicated are expressed as a percentage by mass.
