Description

La présente invention concerne un applicateur et un dispositif d'application d'un produit cosmétique sur les matières kératiniques humaines, notamment la peau ou les ongles.The present invention relates to an applicator and a device for applying a cosmetic product to human keratin materials, in particular the skin or nails.

Par « produit cosmétique », on entend tout produit tel que défini dans le Règlement (CE) n°1223/2009 du Parlement Européen et du Conseil du 30 novembre 2009 relatif aux produits cosmétiques. Ce produit cosmétique peut être, par exemple, un vernis à ongles, un fond de teint, ou un brillant à lèvres."Cosmetic product" means any product as defined in Regulation (EC) No 1223/2009 of the European Parliament and of the Council of 30 November 2009 on cosmetic products. This cosmetic product may be, for example, a nail polish, a foundation, or a lip gloss.

On connaît par le brevet européen EP 0 651 955 un applicateur de vernis à ongles comportant une tige et des poils fixés dans un logement de la tige, ce logement étant de section transversale oblongue.We know by the European patent EP 0 651 955 a nail polish applicator comprising a shaft and bristles fixed in a housing of the shaft, this housing being of oblong cross-section.

On connaît par ailleurs un applicateur de vernis à ongles dont la tige comporte une pluralité de rainures longitudinales réparties de manière sensiblement uniforme sur toute sa périphérie. Les rainures longitudinales permettent au produit déposé le long de la tige de s'écouler de manière préférentielle vers le pinceau.A nail varnish applicator is also known whose stem comprises a plurality of longitudinal grooves distributed in a substantially uniform manner over its entire periphery. The longitudinal grooves allow the product deposited along the rod to flow preferentially to the brush.

On connaît par EP 1 407 685 , un applicateur de vernis à ongles dont la tige comporte une ou deux rainures longitudinales sur sa périphérie.We know by EP 1 407 685 , a nail polish applicator whose stem has one or two longitudinal grooves on its periphery.

Un inconvénient des rainures longitudinales est d'engendrer un écoulement trop rapide du produit vers le pinceau pouvant entrainer des bavures à l'application. De plus la quantité de produit stocké dans la rainure est parfois insuffisante pour l'application d'une plus grande quantité de produit sans recharger le pinceau dans le récipient.A disadvantage of the longitudinal grooves is to generate a too rapid flow of the product to the brush may cause burrs on application. In addition the amount of product stored in the groove is sometimes insufficient for the application of a larger amount of product without reloading the brush in the container.

Le document DE2737667 décrit un applicateur de vernis dont la tige comporte une rainure hélicoïdale s'étendant le long de cette dernière.The document DE2737667 discloses a varnish applicator whose rod has a helical groove extending along the latter.

Il existe un besoin pour faciliter l'application d'un produit, notamment sur les ongles, et permettre de l'étaler plus précisément. La demanderesse a en effet constaté qu'avec les applicateurs connus, le produit qui coule le long des rainures de la tige est relativement difficile à étaler avec précision car il s'écoule trop rapidement.There is a need to facilitate the application of a product, especially on the nails, and allow to spread it more precisely. The Applicant has indeed found that with known applicators, the product flowing along the grooves of the rod is relatively difficult to spread accurately because it flows too quickly.

La présente invention a donc pour objet de fournir un dispositif amélioré d'application d'un produit cosmétique afin de pallier les inconvénients précités.The present invention therefore aims to provide an improved device for applying a cosmetic product to overcome the aforementioned drawbacks.

A cet effet l'invention propose un applicateur comme défini dans la revendication 1.For this purpose the invention provides an applicator as defined in claim 1.

Selon l'invention la tige présente, en se déplaçant le long de l'axe X-X, une succession de sections transversales non-circulaires et décalées angulairement les unes aux autres autour dudit axe X-X de manière à former un motif hélicoïdal.According to the invention the rod has, moving along the axis X-X, a succession of non-circular cross sections and angularly offset from each other about said axis X-X so as to form a helical pattern.

L'invention permet d'obtenir un écoulement moins rapide d'une plus grande quantité de produit.The invention makes it possible to obtain a slower flow of a larger quantity of product.

Selon l'invention, les sections de la succession de sections transversales non-circulaires comportent une excroissance de manière à former une nervure hélicoïdale autour de la tige.According to the invention, the sections of the succession of non-circular cross sections comprise an outgrowth so as to form a helical rib around the rod.

Les sections de la succession de sections transversales non-circulaires peuvent être sensiblement circulaires en dehors de la portion comportant ladite excroissance.The sections of the succession of non-circular cross sections may be substantially circular outside the portion comprising said protrusion.

La nervure présente une pente comprise entre 10° et 70°, et notamment supérieure ou égale à 45° par rapport un axe perpendiculaire à l'axe X-X.The rib has a slope of between 10 ° and 70 °, and in particular greater than or equal to 45 ° with respect to an axis perpendicular to the X-X axis.

Toutes les sections de la succession de sections transversales non-circulaires peuvent être identiques.All sections of the succession of non-circular cross-sections may be identical.

L'organe d'application formé par un pinceau est une touffe de poil fixé dans le logement. La longueur de la portion des poils qui s'étend hors du logement peut alors être comprise entre 5 et 20 mm.The applicator member formed by a brush is a tuft of hair fixed in the housing. The length of the portion of the bristles that extends out of the housing can then be between 5 and 20 mm.

La succession de sections transversales non-circulaires peut s'étendre sur plus de la moitié de la hauteur de la tige.The succession of non-circular cross-sections can extend over more than half the height of the stem.

La succession de sections transversales non-circulaires peut s'étendre jusqu'à l'extrémité libre de la tige.The succession of non-circular cross-sections may extend to the free end of the rod.

La plus grande dimension de l'ouverture du logement, mesurée perpendiculairement à l'axe X-X, peut être inférieure ou égale à 5mm, voire inférieure ou égale à 3 mm.The largest dimension of the opening of the housing, measured perpendicular to the axis X-X, may be less than or equal to 5 mm, or even less than or equal to 3 mm.

La plus grande dimension transversale d'une section de la tige peut être inférieure ou égale à 5 mm.The largest transverse dimension of a section of the rod may be less than or equal to 5 mm.

La tige peut être réalisée d'une seule pièce par moulage de matière thermoplastique avec l'organe de préhension.The rod can be made in one piece by molding thermoplastic material with the gripping member.

L'invention concerne également un dispositif de conditionnement et d'application d'un produit cosmétique comportant un récipient contenant le produit à appliquer, et un applicateur tel que défini précédemment.The invention also relates to a device for packaging and applying a cosmetic product comprising a container containing the product to be applied, and an applicator as defined above.

On a représenté à la figure 1 un dispositif 1 pour l'application d'un produit cosmétique sur les ongles, par exemple un vernis à ongles V. Ce dispositif ne fait pas partie de l'invention, il comporte un récipient 2 contenant le vernis V et un applicateur 3. L'applicateur comporte une tige 4 en matière plastique s'étendant selon un axe longitudinal X-X, munie à une extrémité d'un organe applicateur formé par un pinceau 5 et à l'autre extrémité d'un organe de préhension 10 constituant également un bouchon de fermeture du récipient 2.We have shown figure 1 a device 1 for the application of a cosmetic product to the nails, for example a nail varnish V. This device does not form part of the invention, it comprises a container 2 containing the V varnish and an applicator 3. L applicator comprises a rod 4 of plastic material extending along a longitudinal axis XX, provided at one end with an applicator member formed by a brush 5 and at the other end with a gripping member 10 also constituting a plug of closing the container 2.

En variante non représentée d'autre type d'organe applicateur peuvent également convenir, par exemple l'organe d'application peut être un embout en matière thermoplastique ou en mousse. Ces autres types d'organe applicateur peuvent être adaptés pour des produits cosmétiques différents comme du fond de teint fluide ou un brillant à lèvre, mais ces autres types d'applicateur ne font pas partie de l'invention.Alternatively not shown other type of applicator member may also be suitable, for example the applicator member may be a tip of thermoplastic material or foam. These other types of applicator member may be suitable for different cosmetic products such as fluid foundation or lip gloss, but these other types of applicator are not part of the invention.

L'organe applicateur peut également être floqué.The applicator member may also be flocked.

Le récipient 2 comporte une ouverture définie par un col du récipient 2. Préférentiellement le récipient 2 ne comporte pas de moyen d'essorage de l'organe d'application lorsque ce dernier est retiré de récipient 2.The container 2 has an opening defined by a neck of the container 2. Preferably the container 2 has no means of wringing the applicator member when the latter is removed from the container 2.

Le récipient peut comporter une bille 6, par exemple métallique, permettant d'homogénéiser le vernis V avant l'application, en secouant le dispositif 1.The container may comprise a ball 6, for example metal, to homogenize the V varnish before application, shaking the device 1.

Le récipient peut être transparent ou translucide. A cet effet il peut être réalisé en verre.The container may be transparent or translucent. For this purpose it can be made of glass.

Si l'on se reporte aux figures 2 à 5, ces figures ne faisant pas partie de l'invention, on peut voir que la tige 4 comporte à son extrémité supérieure une jupe 8 permettant sa fixation dans le bouchon de fermeture 10. En variante non représentée, la tige peut être réalisée d'une seule pièce par moulage de matière plastique avec le bouchon de fermeture du récipient.If we refer to Figures 2 to 5 these figures not being part of the invention, it can be seen that the rod 4 has at its upper end a skirt 8 for fixing it in the closure cap 10. As a variant not shown, the rod can be made of a single piece by molding plastic material with the closing cap of the container.

Le bouchon de fermeture 10 est configuré pour se visser ou s'encliqueter sur le col 11 du récipient 2.The closure cap 10 is configured to screw or snap onto the neck 11 of the container 2.

La tige 4 comporte sous la collerette 12 une partie conique 13 pouvant contribuer à l'étanchéité de la fermeture du récipient 2 lorsque l'applicateur 3 est en place sur ce dernier. L'étanchéité pourrait encore être obtenue par coopération de surfaces du bouchon 10 et du col 11 du récipient 2.The rod 4 comprises under the flange 12 a conical portion 13 may contribute to sealing the closure of the container 2 when the applicator 3 is in place on the latter. The seal could be obtained by cooperation of surfaces of the plug 10 and the neck 11 of the container 2.

La tige s'étend sensiblement rectilignement selon l'axe X-X à partir de sa partie conique 13 jusqu'à son extrémité libre 17. La plus grande dimension transversale de la portion de la tige immergée dans le produit contenu dans le récipient lorsque l'applicateur est en place sur celui-ci peut alors être inférieure ou égale à 5 mm.The rod extends substantially rectilinear along the axis XX from its conical portion 13 to its free end 17. The largest transverse dimension of the portion of the rod immersed in the product contained in the container when the applicator is in place on it can then be less than or equal to 5 mm.

La tige 4 comporte également une portion d'extrémité inférieure 14 qui est pourvue d'un logement 15 permettant de fixer l'organe d'application. Dans l'exemple représenté, le logement 15 reçoit une portion des poils du pinceau 5 qui sont fixés par exemple par agrafage, collage, fusion ou surmoulage.The rod 4 also comprises a lower end portion 14 which is provided with a housing 15 for fixing the applicator member. In the example shown, the housing 15 receives a portion of the brush bristles 5 which are fixed for example by stapling, gluing, melting or overmolding.

L'ouverture du logement 15 est sécante avec l'axe longitudinal X-X de la tige 4. Avantageusement l'ouverture est perpendiculaire à cet axe longitudinal X-X.The opening of the housing 15 is secant with the longitudinal axis X-X of the rod 4. Advantageously, the opening is perpendicular to this longitudinal axis X-X.

Le logement 15 peut présenter toute sorte de section transversale par exemple circulaire ou polygonale. Avantageusement le logement 15 présente une ouverture de section transversale rectangulaire ou oblongue, de forme allongée selon un axe perpendiculaire à l'axe longitudinal X-X de la tige 4 ce qui permet d'obtenir une répartition des poils sensiblement homogène.The housing 15 may have any kind of cross section, for example circular or polygonal. Advantageously, the housing 15 has an opening of rectangular or oblong cross-section, of elongate shape along an axis perpendicular to the longitudinal axis XX of the rod 4, which makes it possible to obtain a substantially homogeneous distribution of the bristles.

Le logement 15 peut présenter, comme on peut le voir sur la figure 4, une section transversale qui décroît en direction du fond 19 du logement. Cette diminution pouvant s'effectuer selon la divergence souhaitée pour les poils. Selon la forme donnée au logement 15, on peut obtenir un faisceau de poils plus ou moins large, comme illustré sur les figures 13 et 14. On voit sur la figure 13 qu'en donnant au logement 15 une section transversale sensiblement constante, on obtient un pinceau dont les poils sont relativement serrés, alors qu'en donnant au logement 15 une forme divergeant vers l'extérieur, on permet aux poils de s'écarter davantage les uns des autres afin de former un faisceau relativement large, comma sur la figure 14.The housing 15 can present, as can be seen on the figure 4 , a cross section which decreases towards the bottom 19 of the housing. This reduction can be made according to the desired divergence for the hair. According to the shape given to the housing 15, it is possible to obtain a more or less wide bundle of bristles, as illustrated on the Figures 13 and 14 . We see on the figure 13 by giving the housing 15 a substantially constant cross-section, a brush is obtained, the bristles of which are relatively tight, whereas by giving the housing 15 a shape diverging outwardly, the bristles are allowed to move further apart. each other to form a relatively large beam, as figure 14 .

Le logement 15 peut être réalisé avec dans son fond un renfoncement 15a dans lequel les poils sont fixés sur la tige. Ce renfoncement peut déboucher sur une partie 15b s'évasant en direction de l'ouverture du logement 15, permettant aux poils de s'écarter les uns des autres pour conférer au pinceau une forme élargie et pour que les poils du pinceau 5 s'écartent lorsque le pinceau est appliqué sur l'ongle.The housing 15 can be made with in its bottom a recess 15a in which the bristles are fixed on the rod. This recess may lead to a portion 15b flaring towards the opening of the housing 15, allowing the bristles to move apart from each other to give the brush an enlarged shape and that the bristles of the brush 5 deviate when the brush is applied to the nail.

Le logement 15 peut ainsi être réalisé de telle manière que la dimension transversale maximale I2 du pinceau, mesurée perpendiculairement à l'axe X-X, soit supérieure à la dimension transversale I1 de la tige du niveau du logement 15, comme on le voit sur la figure 14.The housing 15 can thus be made in such a way that the maximum transverse dimension I2 of the brush, measured perpendicularly to the axis XX, is greater than the transverse dimension I1 of the shaft of the level of the housing 15, as can be seen on FIG. figure 14 .

En particulier, le logement peut être agencé de telle sorte que les poils s'étendent à l'extérieur du logement sur une largeur, mesurée perpendiculairement à l'axe X-X, supérieure à la largeur de la tige au niveau du logement. On obtient ainsi un pinceau relativement large.In particular, the housing may be arranged such that the bristles extend outside the housing over a width, measured perpendicular to the X-X axis, greater than the width of the rod at the housing. This gives a relatively wide brush.

La longueur de la portion des poils s'étendant hors du logement 15 de la tige est comprise entre 5 et 20 mm, par exemple.The length of the portion of the bristles extending out of the housing 15 of the shank is between 5 and 20 mm, for example.

Les extrémités libres des poils du pinceau 5 peuvent se situer, par exemple, comme on le voit sur la figure 15, le long d'une courbe C sensiblement circulaire. Ainsi les extrémités libres des poils peuvent décrire sensiblement un arc de cercle, de rayon de courbure compris entre 2 et 15 mm par exemple, notamment compris entre 4 et 10 mm. En variante, les extrémités libres des poils pourraient se situer sensiblement le long d'une droite, par exemple.The free ends of the bristles of the brush 5 can be, for example, as seen on the figure 15 along a substantially circular curve C. Thus the free ends of the bristles can substantially describe an arc of a circle, of radius of curvature of between 2 and 15 mm for example, in particular between 4 and 10 mm. Alternatively, the ends free hair could be located substantially along a line, for example.

La plus grande largeur de l'ouverture du logement, mesurée perpendiculairement à l'axe X-X, peut être inférieure ou égale à 2 mm.The widest opening width of the housing, measured perpendicular to the X-X axis, may be less than or equal to 2 mm.

L'extrémité libre 17 de la tige 4 peut comporter un chanfrein 20, comme on peut le voir sur la figure 4.The free end 17 of the rod 4 may comprise a chamfer 20, as can be seen on the figure 4 .

La tige 4 comporte, dans l'exemple ne faisant pas partie de l'invention et illustré aux figures 1 à 6, sur une majeure partie de sa longueur jusqu'à son extrémité distale 17, une rainure 18. Cette rainure 18 s étend le long et autour de la tige 4 de manière à former une spirale hélicoïdale. Ainsi la tige 4 présente, en se déplaçant le long de l'axe X-X, une succession de sections transversales non-circulaires et décalées angulairement les unes aux autres autour dudit axe X-X de manière à former un motif sous la forme d'une rainure 18 hélicoïdale. Plus précisément, la tige 4 présente une succession de sections dont le contour extérieur comporte une partie circulaire convexe 16b rejoignant les bords d'une concavité 16a définissant la rainure 18.Rod 4 comprises, in the example not forming part of the invention and illustrated in FIGS. Figures 1 to 6 , over a major part of its length to its distal end 17, a groove 18. This groove 18 s extends along and around the rod 4 so as to form a helical spiral. Thus, the rod 4, while moving along the axis XX, has a succession of non-circular and angularly offset cross-sections around said axis XX so as to form a pattern in the form of a groove 18 helical. More specifically, the rod 4 has a succession of sections whose outer contour comprises a convex circular portion 16b joining the edges of a concavity 16a defining the groove 18.

La concavité peut présenter un profil polygonal comme à la figure 5, ou simplement en arc de cercle concave comme à la figure 6.The concavity can present a polygonal profile as in figure 5 , or simply in a concave arc as in the figure 6 .

Cette rainure 18 peut s'étendre sur plus de la moitié de la hauteur de la tige 4. Ladite rainure 18 s'étend préférentiellement à partir de l'extrémité distale 17 de la tige 4, afin de déboucher sur l'organe d'application.This groove 18 can extend over more than half the height of the rod 4. Said groove 18 preferably extends from the distal end 17 of the rod 4, in order to open onto the applicator member .

La rainure présente une pente comprise entre 10° et 70° par rapport un axe Y-Y perpendiculaire à l'axe X-X. Avantageusement la pente est supérieure ou égale à 45° par rapport un axe Y-Y perpendiculaire à l'axe X-X. La pente est notamment adaptée selon la viscosité du produit afin d'obtenir une vitesse d'écoulement adaptée à l'utilisation souhaitée.The groove has a slope of between 10 ° and 70 ° with respect to a Y-Y axis perpendicular to the X-X axis. Advantageously, the slope is greater than or equal to 45 ° with respect to a Y-Y axis perpendicular to the X-X axis. The slope is in particular adapted according to the viscosity of the product in order to obtain a flow rate adapted to the desired use.

La tige peut également comporter plusieurs rainures pouvant s'entrecroiser ou non. Selon l'invention représentée aux figures 7 à 9, la tige comporte une nervure 28 s'étendant le long et autour de la tige de manière à former une nervure hélicoïdale. Ainsi la tige présente, en se déplaçant le long de l'axe X-X, une succession de sections transversales non-circulaires et décalées angulairement les unes aux autres autour dudit axe X-X de manière à former un motif sous la forme d'une nervure hélicoïdale 28. Plus précisément, la tige 4 présente une succession de sections dont le contour extérieur comporte une partie circulaire convexe 26b rejoignant les bords d'une excroissance convexe 26a.The rod may also have several grooves that can intersect or not. According to the invention shown in Figures 7 to 9 , the rod has a rib 28 extending along and around the rod so as to form a helical rib. Thus, the rod presents, as it moves along the axis XX, a succession of non-circular and offset cross-sections. angularly to each other about said axis XX so as to form a pattern in the form of a helical rib 28. More specifically, the rod 4 has a succession of sections whose outer contour comprises a convex circular portion 26b joining the edges of the a convex outgrowth 26a.

L'excroissance peut présenter un profil polygonal comme à la figure 8 ou simplement en arc de cercle concave comme à la figure 9.The outgrowth may have a polygonal profile as in figure 8 or simply in a concave arc as in the figure 9 .

Cette nervure 28 peut s'étendre sur plus de la moitié de la hauteur de la tige 4. Ladite nervure s'étend préférentiellement à partir de l'extrémité distale 17 de la tige 4.This rib 28 may extend over more than half the height of the rod 4. Said rib preferably extends from the distal end 17 of the rod 4.

La nervure 28 présente une pente comprise entre 10° et 70° par rapport un axe Y-Y perpendiculaire à l'axe X-X. Avantageusement la pente est supérieure ou égale à 45° par rapport un axe Y-Y perpendiculaire à l'axe X-XThe rib 28 has a slope of between 10 ° and 70 ° relative to a Y-Y axis perpendicular to the X-X axis. Advantageously, the slope is greater than or equal to 45 ° with respect to a Y-Y axis perpendicular to the X-X axis

En variante représentée aux figures 10 à 12, la tige comporte une section transversale aplatie, et plus particulièrement une succession de sections transversales aplaties, et ladite tige 4 comporte une portion vrillée 38 autour de l'axe longitudinale X-X. Ainsi la tige présente, en se déplaçant le long de l'axe X-X, une succession de sections transversales aplaties, donc non-circulaires, et décalées angulairement les unes aux autres autour dudit axe X-X de manière à former un motif hélicoïdal.As a variant represented in Figures 10 to 12 the rod has a flattened cross-section, and more particularly a succession of flattened cross-sections, and said rod 4 has a twisted portion 38 about the longitudinal axis XX. Thus the rod has, moving along the axis XX, a succession of flattened transverse sections, therefore non-circular, and angularly offset to each other about said axis XX so as to form a helical pattern.

Plus précisément, la tige 4 présente une succession de sections non circulaire par exemple rectangulaire ou oblongues comme sur la figure 11 ou aplatie et présentant une excroissance ou concavité comme à la figure 12.More specifically, the rod 4 has a succession of non-circular sections for example rectangular or oblong as on the figure 11 or flattened and having an outgrowth or concavity as at figure 12 .

Les sections transversales non-circulaires de la succession peuvent être identiques ou varier de façon progressive.The non-circular cross sections of the succession may be identical or vary gradually.

La portion vrillée 38 peut s'étendre sur plus de la moitié de la hauteur de la tige 4 et s'étendre ou non jusqu'à l'extrémité distale 17 de la tige 4.The twisted portion 38 may extend over more than half the height of the rod 4 and extend or not to the distal end 17 of the rod 4.

Le décalage angulaire formant la vrille peut être compris entre un quart de tour et 6 tours. La vrille peut s'étendre sur une longueur comprise entre 10 mm et 70 mm.The angular offset forming the spin can be between a quarter turn and 6 turns. The spin can extend over a length of between 10 mm and 70 mm.

Avantageusement la portion vrillée 38 s'arrête au niveau du fond 19 du logement 15 pour permettre d'avoir un logement non vrillé.Advantageously, the twisted portion 38 stops at the bottom 19 of the housing 15 to allow a non-twisted housing.

Le dispositif 1 s'utilise de la manière suivante.The device 1 is used in the following manner.

L'utilisateur agite le récipient 2 pour permettre à la bille 6 d'homogénéiser le vernis V puis l'utilisateur dévisse le bouchon 10 et se sert du pinceau 5 pour appliquer le produit.The user shakes the container 2 to allow the ball 6 to homogenize the varnish V then the user unscrews the cap 10 and uses the brush 5 to apply the product.

Lorsque l'applicateur 3 est retiré du récipient 2, du produit est présent sur la tige 4 et s'écoule par gravité en direction du pinceau 5. L'épaisseur de produit est plus grande au niveau des nervures 28 lesquelles peuvent retenir davantage de produit.When the applicator 3 is removed from the container 2, the product is present on the rod 4 and flows by gravity towards the brush 5. The thickness of product is greater at the ribs 28 which can retain more product .

Le produit s'écoule en suivant le motif hélicoïdal donc de manière plus lente que s'il s'écoulait axialement le long de la tige. Cela permet d'appliquer plus facilement et plus précisément le produit sans avoir à recharger le pinceau en le replaçant dans le récipient.The product flows in the helical pattern so more slowly than if it flowed axially along the rod. This makes it easier and more precise to apply the product without having to reload the brush by placing it back in the container.

L'invention n'est pas limitée aux exemples illustrés. Les caractéristiques des différents exemples peuvent notamment se combiner au sein de variantes non illustrées, tant que ces variantes sont couvertes par les revendications.The invention is not limited to the illustrated examples. The characteristics of the various examples can in particular be combined within non-illustrated variants, as long as these variants are covered by the claims.

Ainsi il est également possible d'avoir plusieurs nervures ayant des formes identiques ou différentes sur une même tige. De même une tige peut comporter à la fois une rainure et une nervure.Thus it is also possible to have several ribs having identical or different shapes on the same rod. Similarly a rod may have both a groove and a rib.

L'expression « comportant un » doit être comprise comme signifiant « comportant au moins un », sauf si le contraire est spécifié.The expression "comprising a" shall be understood as meaning "containing at least one" unless the contrary is specified.
