(9) A first packaging and application device 10 of the cosmetic product is shown in FIGS. 1 to 7. The device 10 comprises a receptacle 12 intended to contain the cosmetic product, and an applicator 14, removably mounted onto the receptacle 12 and able to apply the cosmetic product.

(10) The cosmetic product is a mascara, a care product, or a cleansing product. In particular, the cosmetic product is a mascara.

(11) The device 10 advantageously has a general cylindrical shape extending along a longitudinal axis (A). The terms “longitudinal” and “radial” are understood generally as relative to the longitudinal axis (A).

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

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

(14) 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 mobile in rotation about the longitudinal axis (A) with respect to the gripping member 16.

(15) 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 cosmetic product application member 22 carried by the rod 20, and a locking system 24 for the selective rotational locking of the rod carrier 18 with respect to the gripping member 16.

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

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

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

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

(20) 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.

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

(22) 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.

(23) 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.

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

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

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

(27) 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.

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

(29) 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.

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

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

(32) 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.

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

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

(35) 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.

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

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

(38) 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.

(39) 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.

(40) 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).

(41) 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.

(42) 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.

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

(44) 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.

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

(46) 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.

(47) 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%.

(48) 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.

(49) 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.

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

(51) The minimum distance l 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.

(52) The first linear contact region 86 has a contact length l1 taken along the longitudinal axis (A) less than 5%, preferably less than 2% of the minimum distance l separating along the axis (A) the first linear contact region 86 and the second linear contact region 90.

(53) Advantageously, the contact length l1 is less than 5%, preferably less than 2% of the diameter D1 of the longitudinal segment 78 taken on the first contact region 86.

(54) The contact length l1 is as such less than 1 mm, and preferably between 0.05 mm and 0.5 mm.

(55) Likewise, the second linear contact region 90 has a contact length l2 taken along the longitudinal axis (A) less than 5%, preferably less than 2% of the minimum distance l separating along the axis (A) the first linear contact region 86 and the second linear contact region 90.

(56) 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.

(57) Advantageously, the contact length l2 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.

(58) The contact length l2 is as such less than 1 mm, and preferably between 0.05 mm and 0.5 mm.

(59) 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 application member 22, 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.

(60) 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.

(61) 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).

(62) 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.

(63) 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.

(64) 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.

(65) 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.

(66) 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 rotational locking of the rod carrier 18 with respect to the receptacle 12 in idle position.

(67) 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.

(68) 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.

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

(70) 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.

(71) 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.

(72) The rod 20 is added in the central housing 104.

(73) The application organ 22 is fixed to the free end of the rod 20. The application organ 22 comprises for example a brush 110 that comprises substantial radial bristles.

(74) The locking system 24 for the selective rotational locking of the rod carrier 18 with respect to the gripping member 16 is shown in FIGS. 5 to 7.

(75) The locking system 24 is operable 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 locked in rotation with respect to the gripping member 16. The term entirely locked here means a “frank” contact of elements abutting against one another, and not only a friction contact.

(76) The locking 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.

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

(78) 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.

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

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

(81) 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.

(82) 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 locking, in order to lock 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.

(83) A process for applying a cosmetic product, for example on keratinous fibers of a user by means of the device 10 shall now be described.

(84) Initially, a device 10 is provided with the applicator 14 in idle position, mounted and immobilized on the receptacle 12.

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

(86) 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, locking in rotation about the axis (A) the rod carrier 18 with respect to the gripping member 16.

(87) 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 locking system 24 active. Then, the user extracts the rod carrier 18 and the application member 22 outside of the receptacle 12 through the opening 28. The squeezing device 32 removes from the brush 110 the excess product that accompanies the exit thereof from the receptacle 12.

(88) The user brings the cosmetic product application member 22 in contact with keratinous fibers.

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

(90) The displacement is accompanied by the depositing of the cosmetic product on the keratinous fibers.

(91) 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.

(92) The friction with the keratinous fibers, which are applied on the application member 22 during the application of the cosmetic product, very easily cause the rod 20 to rotate with respect to the gripping member 16.

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

(94) The application of product is therefore very effective, for a reduced number of contacts with the keratinous fibers. A swelling effect is also produced on the fibers.

(95) Alternatively, the user can selectively rotationally lock of the rod carrier 18 with respect to the gripping member 16 at any time, in particular during the application of the product.

(96) 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.

(97) 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.

(98) Alternatively, and according to an advantageous arrangement, the locking 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.
