The enclosure extends around the application element for a length of 6.8 or 10 millimeters.

Description

La présente invention concerne les dispositifs de conditionnement et d'application comportant un réservoir contenant au moins un produit à appliquer et un élément d'application solidaire du réservoir au moins durant l'application.The present invention relates to packaging and application devices comprising a reservoir containing at least one product to be applied and an applicator element integral with the reservoir at least during application.

La demande de brevet européen EP 1 557 111 divulgue un dispositif de ce type dans lequel l'élément d'application peut être constitué par une touffe de poils agrafée dans un logement d'un porte-élément d'application.The patent application European EP 1,557,111 discloses a device of this type in which the applicator element may be constituted by a tuft of stapled hairs in a housing of an applicator element holder.

Le produit est amené à l'extérieur de l'élément d'application au travers d'orifices du porte-élément d'application.The product is brought outside the applicator element through openings of the applicator element holder.

La distribution du produit peut s'effectuer par exemple en pressant sur la paroi du réservoir, lorsque celle-ci est souple.The distribution of the product can be effected for example by pressing on the tank wall, when the latter is flexible.

Le produit est distribué à la base des poils dans une zone où ceux-ci sont très proches les uns des autres, ce qui ne permet pas au produit de s'immiscer facilement entre eux dès la base du faisceau.The product is distributed at the base of the hairs in an area where they are very close to each other, which does not allow the product to easily interfere with each other at the base of the beam.

L'imprégnation du faisceau de poils peut s'avérer ainsi insuffisante dans certains cas.The impregnation of the hair bundle may thus be insufficient in some cases.

De plus, il existe le risque qu'un excès de produit soit délivré sur l'élément d'application, car une fois les orifices du porte-élément d'application traversés, le produit s'écoule sans être freiné sur l'élément d'application.In addition, there is the risk that an excess of product is delivered on the applicator element, because once the orifices of the application element holder crossed, the product flows without being braked on the element d 'application.

Le brevet US 2 155 688 décrit un dispositif pour distribuer un produit relativement visqueux tel qu'un rouge à lèvres, ce produit étant contenu dans un réservoir muni d'un piston et d'un mécanisme permettant de déplacer celui-ci en direction de la sortie.The patent US 2,155,688 discloses a device for dispensing a relatively viscous product such as a lipstick, which product is contained in a reservoir provided with a piston and a mechanism for moving the latter towards the outlet.

Il existe un besoin pour améliorer encore les dispositifs de conditionnement et d'application comportant un réservoir, un élément d'application solidaire de celui-ci au moins durant l'application et un porte-élément d'application.There is a need to further improve the packaging and application devices comprising a reservoir, an integral application member thereof at least during application and an application member holder.

L'invention vise à répondre à ce besoin et y parvient grâce à un dispositif de conditionnement et d'application comportant :

  • un réservoir contenant au moins un produit à appliquer,
  • un élément d'application solidaire du réservoir au moins durant l'application,
  • un porte-élément d'application,
  • un support servant à la fixation du porte-élément d'application sur le réservoir, comportant une enveloppe tubulaire entourant le porte-élément d'application et l'élément d'application sur au moins une portion de sa longueur, l'enveloppe tubulaire et le porte-élément d'application présentant des surfaces en regard venant en contact.
The invention aims to meet this need and achieves this through a packaging and application device comprising:
  • a reservoir containing at least one product to be applied,
  • an application element integral with the reservoir at least during the application,
  • an application element holder,
  • a support for fixing the applicator element holder on the reservoir, comprising a tubular casing surrounding the applicator element holder and the applicator element over at least a portion of its length, the tubular casing and the applicator holder having facing surfaces coming into contact.

Au moins un canal longitudinal peut être formé en creux sur l'une de ces surfaces en regard pour la circulation du produit provenant du réservoir vers l'élément d'application. Plusieurs canaux longitudinaux peuvent être formés et répartis angulairement autour de l'axe longitudinal du dispositif.At least one longitudinal channel may be recessed on one of the facing surfaces for the flow of product from the reservoir to the applicator member. Several longitudinal channels may be formed and angularly distributed about the longitudinal axis of the device.

L'invention permet ainsi de créer un ou plusieurs canaux de section relativement faible entre le porte-élément d'application et le support, de façon à créer une perte de charge relativement importante, capable de ralentir l'écoulement du produit même en cas de pression relativement forte du produit dans le réservoir.The invention thus makes it possible to create one or more channels of relatively small cross-section between the applicator element holder and the support, so as to create a relatively large pressure drop, capable of slowing down the flow of the product even in case of relatively high pressure of the product in the tank.

De plus, le support en entourant l'élément d'application permet de créer une chambre intermédiaire dans laquelle débouche le ou les canaux longitudinaux, améliorant l'imprégnation des poils par le produit.In addition, the support surrounding the applicator element makes it possible to create an intermediate chamber into which the longitudinal channel (s) opens out, improving the impregnation of the bristles by the product.

La qualité de l'application et le confort d'utilisation s'en trouvent améliorés et l'invention permet d'adapter plus facilement le dispositif à un produit présentant des caractéristiques rhéologiques données, en choisissant par exemple la taille et le nombre des canaux longitudinaux ainsi que la longueur sur laquelle l'élément d'application est recouvert par l'enveloppe tubulaire du support.The quality of the application and the ease of use are improved and the invention makes it easier to adapt the device to a product having given rheological characteristics, for example by choosing the size and the number of longitudinal channels. as well as the length over which the applicator element is covered by the tubular casing of the support.

Dans un exemple de mise en oeuvre de l'invention, l'enveloppe tubulaire s'étend ainsi autour de l'élément d'application sur une longueur d'au moins 4 mm, voire d'au moins 6, 8 ou 10 mm, ce qui permet d'imprégner de façon satisfaisante l'élément d'application.In an exemplary implementation of the invention, the tubular casing thus extends around the applicator element over a length of at least 4 mm, or even at least 6, 8 or 10 mm, which makes it possible to impregnate satisfactorily the application element.

L'enveloppe tubulaire peut être terminée par une portion convergente, définissant une ouverture traversée par l'élément d'application.The tubular casing may be terminated by a convergent portion, defining an opening through which the applicator element passes.

La présence de cette ouverture permet de définir la forme extérieure de l'élément d'application lorsque celui-ci est un faisceau de poils, la géométrie de cette ouverture étant choisie en fonction de la forme à donner au faisceau de poils, ceux-ci venant au contact du bord de l'ouverture.The presence of this opening makes it possible to define the external shape of the applicator element when it is a bundle of bristles, the geometry of this opening being chosen according to the shape to be given to the bundle of bristles, these coming into contact with the edge of the opening.

Le support peut être réalisé d'une seule pièce, notamment par moulage d'une matière thermoplastique, avec l'enveloppe tubulaire et avec au moins une jupe de fixation sur le réservoir, notamment une jupe filetée.The support may be made in one piece, in particular by molding a thermoplastic material, with the tubular casing and with at least one fixing skirt on the reservoir, in particular a threaded skirt.

Le support peut également être réalisé avec une deuxième jupe filetée permettant la fixation sur le dispositif d'un capot de fermeture.The support can also be made with a second threaded skirt for fixing on the device a closure cap.

Le porte-élément d'application peut comporter un logement à une extrémité, permettant la fixation d'une touffe de poils par agrafage.The applicator element holder may comprise a housing at one end, allowing the attachment of a tuft of bristles by stapling.

Ce logement peut être centré sur l'axe longitudinal du dispositif et être borgne.This housing can be centered on the longitudinal axis of the device and be blind.

Le logement peut présenter une section transversale s'élargissant vers l'extérieur. Le logement peut présenter, par exemple, une forme conique en coupe longitudinale, sur au moins une fraction de sa longueur.The housing may have a cross section widening outwardly. The housing may have, for example, a conical shape in longitudinal section, over at least a fraction of its length.

Un élargissement de la section transversale du logement peut permettre aux poils de s'écarter plus facilement les uns des autres hors du logement.An enlargement of the cross section of the housing may allow the bristles to move more easily out of the housing.

Les poils peuvent ainsi occuper davantage la chambre intermédiaire, ce qui peut améliorer leur imprégnation et ralentir l'écoulement du produit.The bristles can thus occupy more the intermediate chamber, which can improve their impregnation and slow down the flow of the product.

La retenue du porte-élément d'application dans le support peut s'effectuer par friction, notamment par serrage des surfaces précitées venant en contact.The retention of the applicator element holder in the support can be carried out by friction, in particular by clamping the aforementioned surfaces coming into contact.

Le porte-élément d'application peut être réalisé avec des nervures longitudinales à sa périphérie et le support peut comporter une surface en regard cylindrique de révolution. En variante, le support peut être réalisé avec des nervures sur sa surface radialement intérieure et le porte-élément d'application peut présenter une surface en regard cylindrique de révolution.The applicator element holder may be made with longitudinal ribs at its periphery and the support may comprise a cylindrical facing surface of revolution. As a variant, the support may be made with ribs on its radially inner surface and the applicator-element holder may have a cylindrical facing surface of revolution.

Le support peut être réalisé avec au moins une lèvre annulaire d'étanchéité venant s'appliquer sur le capot de fermeture lorsque celui-ci est en place sur le support.The support may be made with at least one annular sealing lip which is applied to the closure cap when it is in place on the support.

Le support peut également être réalisé avec une lèvre annulaire d'étanchéité s'appliquant sur un col du réservoir.The support can also be achieved with an annular sealing lip on a neck of the reservoir.

Le support et le réservoir peuvent être réalisés de façon à permettre un vissage du support sur le réservoir et empêcher le dévissage du support. L'un au moins du réservoir et du support peut notamment être réalisé avec, à la base du col, au moins un premier relief et l'autre au moins un deuxième relief agencé pour coopérer avec le premier afin de permettre le vissage tout en s'opposant au dévissage. Le premier relief est par exemple un cran d'anti-rotation et le deuxième relief un autre cran d'anti-rotation.The support and the reservoir can be made so as to allow screwing of the support on the reservoir and prevent the unscrewing of the support. At least one of the reservoir and the support may in particular be made with, at the base of the neck, at least one first relief and the other at least one second relief arranged to cooperate with the first to allow screwing while s opponent to unscrewing. The first relief is for example an anti-rotation notch and the second relief another anti-rotation notch.

Le porte-élément d'application peut être réalisé avec une collerette venant axialement en appui contre un décrochement du support de façon à limiter son enfoncement axial dans celui-ci.The applicator element holder may be made with a flange axially bearing against a recess of the support so as to limit its axial insertion therein.

Le produit contenu dans le réservoir peut être un produit à appliquer sur les ongles, notamment un vernis à ongles.The product contained in the reservoir may be a product to be applied to the nails, especially a nail polish.

L'invention a encore pour objet, selon un autre de ses aspects, un dispositif dans lequel l'enveloppe tubulaire présente une portion convergente définissant une ouverture traversée par l'élément d'application, celui-ci étant un faisceau de poils venant au contact du bord de cette ouverture, indépendamment de la présence ou non d'un ou plusieurs canaux longitudinaux formés entre des surfaces en regard du porte-élément d'application et du support. Le faisceau de poils peut être fixé dans un logement du porte-élément d'application ayant une section transversale s'élargissant vers l'extérieur, le logement ayant par exemple une forme conique en coupe longitudinale.The invention further relates, in another of its aspects, to a device in which the tubular casing has a convergent portion defining an opening through which the applicator element passes, the latter being a bundle of bristles coming into contact with each other. from the edge of this opening, regardless of the presence or absence of one or more longitudinal channels formed between facing surfaces of the holder application element and the support. The bundle of bristles may be fixed in a housing of the applicator member having an outwardly widening cross-section, the housing having for example a conical shape in longitudinal section.

Le support 4 comporte, dans l'exemple illustré, une lèvre annulaire d'étanchéité 23 qui s'applique sur une surface radialement intérieure 24 du capot 20 lorsque celui-ci est vissé sur le support 4, de façon à délimiter à l'intérieur du capot 20 un espace intérieur 56 étanche, réduisant le risque de séchage du produit présent sur l'élément d'application 6 en l'absence d'utilisation.The support 4 comprises, in the example illustrated, an annular sealing lip 23 which is applied to a radially inner surface 24 of the cover 20 when the latter is screwed onto the support 4, so as to delimit on the inside. the hood 20 a sealed interior space 56, reducing the risk of drying the product present on the application element 6 in the absence of use.

Le capot 20 peut contenir du produit autour de l'élément d'application, le cas échéant.The cover 20 may contain product around the applicator element, if necessary.

Dans l'exemple considéré, l'élément d'application est un faisceau de poils formé par l'agrafage d'une touffe de poils dans un logement borgne 30 du porte-élément d'application. Ce logement 30 présente dans l'exemple considéré une forme généralement cylindrique de révolution autour de l'axe longitudinal X du dispositif.In the example under consideration, the applicator element is a bundle of bristles formed by the stapling of a tuft of bristles in a blind housing 30 of the applicator element holder. This housing 30 has in the example considered a generally cylindrical shape of revolution about the longitudinal axis X of the device.

Dans la variante illustrée à la figure 4, le logement 30 présente en coupe longitudinale une forme conique.In the variant illustrated in Figure 4, the housing 30 has a longitudinal section of a conical shape.

L'élargissement de la section transversale du logement 30 permet aux poils de s'écarter plus facilement les uns des autres.The widening of the cross section of the housing 30 allows the bristles to move apart more easily.

L'angle au sommet α du cône définissant le logement 30 est de préférence compris entre 15 et 25°, de préférence d'environ 20°. Le logement 30 présente un fond circulaire 31 de diamètre D31 de préférence compris entre 1,5 et 1,9 mm, de préférence d'environ 1,7 mm, et une ouverture 32 circulaire, d'un diamètre de préférence compris entre 2,2 et 2,6 mm, de préférence encore d'environ 2,4 mm. Le fond 31 et l'ouverture 32 sont coaxiaux d'axe X. Avantageusement, cette conformation permet d'obtenir une touffe en éventail.The apex angle α of the cone defining the housing 30 is preferably between 15 and 25 °, preferably about 20 °. The housing 30 has a circular bottom 31 of diameter D 31 preferably between 1.5 and 1.9 mm, preferably about 1.7 mm, and a circular opening 32, with a diameter preferably between 2 , 2 and 2.6 mm, more preferably about 2.4 mm. The bottom 31 and the opening 32 are coaxial with axis X. Advantageously, this conformation makes it possible to obtain a fan tuft.

La lèvre d'étanchéité 23 est portée par une enveloppe tubulaire 26 du support 4 qui se raccorde inférieurement à la paroi transversale 16 et qui se prolonge supérieurement au-delà du porte-élément d'application 5, de façon à définir autour de l'élément d'application 6 une chambre intermédiaire 44. Cette dernière comprend un espace annulaire 60 entre l'extrémité du porte-élément d'application 5 comprenant le logement 30 et l'enveloppe 26.The sealing lip 23 is carried by a tubular envelope 26 of the support 4 which is connected inferiorly to the transverse wall 16 and which extends more than beyond the applicator element holder 5, so as to define around the application member 6 an intermediate chamber 44. The latter comprises an annular space 60 between the end of the applicator element holder 5 comprising the housing 30 and the envelope 26.

Comme représenté sur la figure 5, le logement 30 et la chambre intermédiaire d'imprégnation 44 sont de préférence configurés de manière que la touffe 6 entre en contact avec la surface intérieure 65 de la paroi délimitant la chambre d'imprégnation 44 à partir d'une ligne d'impact 66. De préférence, la distance l66, selon l'axe X, entre l'ouverture 32 du logement 30 et la ligne d'impact 66 est comprise entre 2 et 6 mm, de préférence entre 3 et 5 mm, de préférence d'environ 4 mm.As shown in FIG. 5, the housing 30 and the intermediate impregnation chamber 44 are preferably configured in such a way that the tuft 6 comes into contact with the inner surface 65 of the wall delimiting the impregnation chamber 44 from an impact line 66. Preferably, the distance l 66 , along the axis X, between the opening 32 of the housing 30 and the impact line 66 is between 2 and 6 mm, preferably between 3 and 5 mm. mm, preferably about 4 mm.

Le diamètre intérieur D66 de la chambre d'imprégnation 44 au niveau de la ligne d'impact 66 est de préférence compris entre 3,6 et 4 mm, de préférence d'environ 3,8 mm.The inside diameter D 66 of the impregnation chamber 44 at the level of the impact line 66 is preferably between 3.6 and 4 mm, preferably about 3.8 mm.

L'enveloppe tubulaire 26 présente à partir d'une ligne de rupture 27 une portion distale 28 qui est convergente et qui définit à son extrémité supérieure une ouverture 29 pour le passage de l'élément d'application 6.The tubular casing 26 presents from a rupture line 27 a distal portion 28 which is convergent and which defines at its upper end an opening 29 for the passage of the applicator element 6.

De préférence, la distance selon l'axe X entre la ligne de rupture 27 et l'ouverture 29 est comprise entre 3 et 4 mm, et de préférence est d'environ 3,5 mm.Preferably, the distance along the X axis between the break line 27 and the aperture 29 is between 3 and 4 mm, and preferably is about 3.5 mm.

Cette distance est référencée l29 sur la figure 5.This distance is referenced l 29 in FIG.

De même, la distance selon l'axe X entre la ligne d'impact 66 et la ligne de rupture 27, référencée l27, est de préférence comprise entre 2,3 et 2,7 mm, de préférence encore d'environ 2,5 mm.Similarly, the distance along the axis X between the impact line 66 and the breaking line 27, referenced 1 27 , is preferably between 2.3 and 2.7 mm, more preferably about 2, 5 mm.

Compte tenu de la forme en éventail de la touffe de poils 6, et de l'étranglement progressif de la chambre d'imprégnation 44 vers l'ouverture 29, la touffe de poils 6 reste substantiellement en contact avec la surface intérieure 65 délimitant la chambre d'imprégnation depuis la ligne d'impact 66 jusqu'à l'ouverture 29 sur une distance le (=l 29 + l 27) d'au moins 4 mm, de préférence supérieure à 5 mm et/ou inférieure à 8 mm, de préférence inférieure à 7 mm, de préférence encore d'environ 6 mm. Sur cette portion de la chambre d'imprégnation, dite « portion de contact », la touffe de poils 6 obstrue donc la chambre d'imprégnation. Cette obstruction limite avantageusement la quantité de produit sortant par l'ouverture 29. Cette configuration empêche également la formation de bulles d'air dans la touffe de poils et conduit donc à une imprégnation homogène de ladite touffe.Taking into account the fan shape of the tuft of bristles 6, and the progressive restriction of the impregnation chamber 44 towards the opening 29, the tuft of bristles 6 remains substantially in contact with the inner surface 65 delimiting the chamber impregnation from the impact line 66 to the opening 29 over a distance I e (= 1 29 + 1 27 ) of at least 4 mm, preferably greater than 5 mm and / or less than 8 mm preferably less than 7 mm, more preferably about 6 mm. On this portion of the impregnation chamber, called "contact portion", the tuft of bristles 6 thus obstructs the impregnation chamber. This obstruction limits advantageously the amount of product exiting through the opening 29. This configuration also prevents the formation of air bubbles in the tuft of bristles and thus leads to a homogeneous impregnation of said tuft.

L'ouverture 29 présente par exemple une section circulaire présentant de préférence un diamètre compris entre 2,6 et 3 mm, de préférence encore d'environ 2,8 mm, mais celle-ci pourrait être différente selon la forme à donner à l'élément d'application 6.The opening 29 has for example a circular section preferably having a diameter between 2.6 and 3 mm, more preferably about 2.8 mm, but this could be different depending on the shape to be given to the application element 6.

De préférence, la touffe de poils 6 s'étend, au-delà de l'ouverture 29, hors de la chambre d'imprégnation 44, sur une longueur l' comprise entre 8 et 11 mm.Preferably, the tuft of bristles 6 extends beyond the opening 29, out of the impregnation chamber 44, a length l 'of between 8 and 11 mm.

Le porte-élément d'application 5 comporte un corps 33 qui présente sur sa surface radialement extérieure des nervures longitudinales 36, comme on peut le voir sur la figure 2, lesquelles viennent en appui contre la surface radialement intérieure 38 d'une portion 58 de l'enveloppe tubulaire 26, symétrique de révolution autour de l'axe X. Il se forme ainsi entre l'enveloppe tubulaire 26 et le corps 33 du porte-élément d'application des canaux longitudinaux 40 qui permettent au produit contenu dans le réservoir 2 de s'écouler entre le porte-élément d'application 5 et l'enveloppe tubulaire 6 et de gagner la chambre intermédiaire 44.The applicator element holder 5 comprises a body 33 which has on its radially outer surface longitudinal ribs 36, as can be seen in FIG. 2, which bear against the radially inner surface 38 of a portion 58 of the tubular casing 26, symmetrical of revolution about the axis X. It is thus formed between the tubular casing 26 and the body 33 of the application element holder of the longitudinal channels 40 which allow the product contained in the reservoir 2 to flow between the applicator element holder 5 and the tubular casing 6 and to gain the intermediate chamber 44.

Le porte-élément d'application 5 comporte, en partie inférieure, une collerette 48 qui vient axialement en appui contre un décrochement intérieur 49 à la base de l'enveloppe tubulaire 26, cette collerette 48 étant traversée par des ouvertures 50 pour la circulation du produit.The applicator element holder 5 comprises, in the lower part, a flange 48 which comes axially in abutment against an inner recess 49 at the base of the tubular envelope 26, this flange 48 being traversed by openings 50 for the circulation of the product.

Le corps 33 peut comporter un évidement 31 à son extrémité inférieure, lequel peut faciliter sa manipulation et son insertion dans l'enveloppe tubulaire 26.The body 33 may comprise a recess 31 at its lower end, which may facilitate its handling and insertion into the tubular envelope 26.

Le porte-élément d'application 5 est, dans l'exemple considéré, retenu par serrage à l'intérieur de l'enveloppe tubulaire 26 grâce aux nervures 36 qui viennent en appui contre la surface intérieure 38.In this example, the applicator element holder 5 is clamped inside the tubular casing 26 by virtue of the ribs 36 which abut against the inner surface 38.

La présence de produit dans la chambre intermédiaire 44 permet une bonne imprégnation des poils hors du logement 30 et le cas échéant le gonflement du faisceau de poils.The presence of product in the intermediate chamber 44 allows good impregnation of the bristles out of the housing 30 and optionally the swelling of the bundle of bristles.

Dans l'exemple illustré, l'ouverture 29 se situe sensiblement à mi-longueur de l'élément d'application 6 et ce dernier s'étend hors du logement 30 sur une distance l d'au moins 4 mm, voire au moins 6, 8 ou 10 mm, à l'intérieur de la chambre intermédiaire.In the example shown, the opening 29 is located substantially mid-length of the application element 6 and the latter extends out of the housing 30 over a distance l of at least 4 mm, or even at least 6 , 8 or 10 mm, inside the intermediate chamber.

De préférence, la distance l, entre l'ouverture 32 du logement 30 et l'ouverture 29 de la chambre d'imprégnation, est comprise entre 8 et 12 mm.Preferably, the distance 1 between the opening 32 of the housing 30 and the opening 29 of the impregnation chamber is between 8 and 12 mm.

On ne sort pas du cadre de la présente invention s'il en est autrement, par exemple en raccourcissant ou en augmentant la longueur de la chambre intermédiaire 44.It is not beyond the scope of the present invention if it is otherwise, for example by shortening or increasing the length of the intermediate chamber 44.

Le réservoir 2 est par exemple réalisé avec une paroi souple, ce qui permet à l'utilisateur, en pressant celle-ci, de forcer le passage de produit à travers les canaux longitudinaux 40.The reservoir 2 is for example made with a flexible wall, which allows the user, by pressing the latter, to force the passage of product through the longitudinal channels 40.

La présence de la chambre intermédiaire 44 freine l'écoulement du produit sur l'élément d'application 6. De plus, la perte de charge créée par la circulation dans les canaux 40 évite, en cas de pression brutale exercée sur la paroi du réservoir 2, qu'un excès de produit n'arrive sur l'élément d'application 6 trop rapidement.The presence of the intermediate chamber 44 brakes the flow of the product on the application element 6. In addition, the pressure drop created by the circulation in the channels 40 prevents, in case of sudden pressure exerted on the wall of the reservoir 2, an excess of product does not arrive on the application element 6 too quickly.

Dans la variante de la figure 3, les nervures 36 sont réalisées sur la surface radialement intérieure de l'enveloppe tubulaire 26, le corps 33 présentant une surface en regard de ces nervures qui est par exemple symétrique de révolution autour de l'axe X.In the variant of Figure 3, the ribs 36 are formed on the radially inner surface of the tubular casing 26, the body 33 having a surface facing these ribs which is for example symmetrical about the X axis.

L'invention n'est pas limitée aux exemples qui viennent d'être décrits.The invention is not limited to the examples which have just been described.

Par exemple, la fixation du porte-élément d'application sur le réservoir peut s'effectuer avec un support ayant une forme différente.For example, the attachment of the applicator element holder to the reservoir can be performed with a support having a different shape.

L'expression « comportant un » doit être comprise comme étant synonyme de l'expression « comportant au moins un », sauf si le contraire est spécifié.The expression "having one" shall be understood as being synonymous with the expression "having at least one" unless the contrary is specified.
