Definitions

  • the present invention relates to devices for packaging and applying a cosmetic or care product.
  • French patent application FR 2 771 077 describes a packaging and applicator device comprising an applicator having an applicator element that can be refilled with product by being introduced into a container through a wiper member consisting of at least one partly by an elastically deformable porous material.
  • a wiper member consisting of at least one partly by an elastically deformable porous material.
  • Such a device is relatively complex and expensive to produce and further the rod of the applicator is made with a small diameter so as not to deform the wiper member.
  • the rod is thus relatively flexible, which can affect the accuracy of the makeup.
  • European patent EP 1 053 695 B1 also discloses an applicator comprising an applicator element that can deform on crossing the wiper member.
  • the application surface is relatively narrow and the comfort to the application is not entirely satisfactory.
  • No. 3,692,417 describes a mascara brush whose bristles bend as they pass through the opening of the container.
  • the invention aims in particular to provide an applicator both comfortable and accurate and having sufficient autonomy to allow application in good conditions.
  • the cavity is advantageously at least partially defined by at least two branches, at least partially flocked, of the application element.
  • the applicator element may have a relatively wide application surface, which contributes to making the device relatively fast and comfortable to use, especially in the case of an application on the skin or lips.
  • the application element offers new possibilities of application of the product according to the orientation given to the application element relative to keratinous fibers.
  • the branches can define a larger width of the application element.
  • the cavity may make it possible to constitute, when it is made so as to be able to load the product, a reserve of product providing additional autonomy to the application element or making it easier to deposit a larger quantity of product, in order to to reinforce a makeup effect, for example the gloss of a gloss.
  • the invention makes it possible to use as a wiper member, if desired, a wiper member which deforms relatively little, if not substantially when it is traversed by the applicator element and in particular a wiper member.
  • a wiper member which deforms relatively little, if not substantially when it is traversed by the applicator element and in particular a wiper member.

The applicator element comprises at least one inner cavity defined between at least two branches that are at least partially flocked and an outside cross-section of the applicator element is large enough for the applicator element to deform while passing through the opening of the receptacle. The deformation results in a shape of the cavity that is modified. The applicator element includes a body made of thermoplastic material. The receptacle includes a wiper member made of non-cellular material e.g. polyolefin and/or elastomer. The cavity is filled with an elastically deformable porous material. An independent claim is included for the applicator.

Description

La présente invention concerne les dispositifs de conditionnement et d'application d'un produit cosmétique ou de soin.The present invention relates to devices for packaging and applying a cosmetic or care product.

La demande de brevet français FR 2 771 077 décrit un dispositif de conditionnement et d'application comportant un applicateur ayant un élément d'application pouvant être rechargé en produit en étant introduit dans un récipient au travers d'un organe d'essorage constitué au moins en partie par un matériau poreux élastiquement déformable. Un tel dispositif est relativement complexe et coûteux à réaliser et en outre la tige de l'applicateur est réalisée avec un faible diamètre de manière à ne pas déformer l'organe d'essorage. La tige est ainsi relativement souple, ce qui peut nuire à la précision du maquillage.French patent application FR 2 771 077 describes a packaging and applicator device comprising an applicator having an applicator element that can be refilled with product by being introduced into a container through a wiper member consisting of at least one partly by an elastically deformable porous material. Such a device is relatively complex and expensive to produce and further the rod of the applicator is made with a small diameter so as not to deform the wiper member. The rod is thus relatively flexible, which can affect the accuracy of the makeup.

On connaît par ailleurs par le brevet européen EP 1 053 695 B1 un applicateur comportant un élément d'application pouvant se déformer au franchissement de l'organe d'essorage. La surface d'application est relativement étroite et le confort à l'application n'est pas entièrement satisfaisant.European patent EP 1 053 695 B1 also discloses an applicator comprising an applicator element that can deform on crossing the wiper member. The application surface is relatively narrow and the comfort to the application is not entirely satisfactory.

D'autres applicateurs sont décrits dans US 2002/0005209 A1, US 6 120 202, US 6 305 861 B1, EP 693 261 A1 et EP 0 875 169 A1 notamment.Other applicators are described in US 2002/0005209 A1, US 6 120 202, US 6 305 861 B1, EP 693 261 A1 and EP 0 875 169 A1 in particular.

US 4 411 282 et US 5 826 600 divulguent des applicateurs de mascara comportant des disques empilés, qui se déforment lorsque l'applicateur est extrait du récipient.US 4,411,282 and US 5,826,600 disclose mascara applicators having stacked discs that deform when the applicator is removed from the container.

US 3 692 417 décrit une brosse à mascara dont les poils fléchissent lors du passage à travers l'ouverture du récipient.No. 3,692,417 describes a mascara brush whose bristles bend as they pass through the opening of the container.

L'invention vise notamment à proposer un applicateur à la fois confortable et précis et ayant une autonomie suffisante pour permettre une application dans de bonnes conditions.The invention aims in particular to provide an applicator both comfortable and accurate and having sufficient autonomy to allow application in good conditions.

L'invention a pour objet, selon un premier de ses aspects, un dispositif de conditionnement et d'application, comportant :

  • un applicateur comportant un élément d'application au moins partiellement élastiquement déformable,
  • un récipient contenant un produit à appliquer, dans lequel l'élément d'application peut être logé en l'absence d'utilisation, le récipient présentant une ouverture pouvant être traversée par l'élément d'application lorsque celui-ci est extrait du récipient, ce dispositif pouvant se caractériser par le fait que l'élément d'application présente au moins une cavité intérieure et par le fait que sa section transversale extérieure est suffisamment grande pour que l'élément d'application se déforme lors de la traversée de l'ouverture, cette déformation s'accompagnant d'une modification de la forme de la cavité.
The subject of the invention is, according to a first of its aspects, a device for packaging and application, comprising:
  • an applicator comprising an application element that is at least partially elastically deformable,
  • a container containing a product to be applied, in which the applicator element can be housed in the absence of use, the container having an opening that can be traversed by the applicator element when it is extracted from the container , this device being able to be characterized in that the applicator element has at least one internal cavity and in that its external cross section is sufficiently large for the application element to deform during the crossing of the opening, this deformation being accompanied by a modification of the shape of the cavity.

La cavité est avantageusement définies au moins partiellement par au moins deux branches, au moins partiellement floquées, de l'élément d'application.The cavity is advantageously at least partially defined by at least two branches, at least partially flocked, of the application element.

L'élément d'application peut présenter une surface d'application relativement large, ce qui contribue à rendre le dispositif relativement rapide et confortable à utiliser, notamment dans le cas d'une application sur la peau ou les lèvres.The applicator element may have a relatively wide application surface, which contributes to making the device relatively fast and comfortable to use, especially in the case of an application on the skin or lips.

Lorsque le dispositif est destiné au maquillage ou au traitement des cils ou sourcils, l'élément d'application offre de nouvelles possibilités d'application du produit selon l'orientation donnée à l'élément d'application relativement aux fibres kératiniques.When the device is intended for the makeup or treatment of eyelashes or eyebrows, the application element offers new possibilities of application of the product according to the orientation given to the application element relative to keratinous fibers.

Les branches peuvent définir une plus grande largeur de l'élément d'application.The branches can define a larger width of the application element.

La cavité peut permettre de constituer, lorsqu'elle est réalisée de manière à pouvoir se charger en produit, une réserve de produit procurant une autonomie supplémentaire à l'élément d'application ou permettant de déposer plus facilement une quantité plus importante de produit, afin de renforcer un effet du maquillage, par exemple la brillance d'un gloss.The cavity may make it possible to constitute, when it is made so as to be able to load the product, a reserve of product providing additional autonomy to the application element or making it easier to deposit a larger quantity of product, in order to to reinforce a makeup effect, for example the gloss of a gloss.

L'invention permet d'utiliser comme organe d'essorage, si on le souhaite, un organe d'essorage qui se déforme relativement peu, sinon sensiblement pas lorsqu'il est traversé par l'élément d'application et notamment un organe d'essorage réalisé dans une matière non alvéolaire, par exemple une polyoléfme telle que le polyéthylène basse densité ou un élastomère, de sorte que l'organe d'essorage peut être relativement peu coûteux à fabriquer et facile à installer sur le récipient. Le cas échéant, l'organe d'essorage peut comporter une ou plusieurs fentes pour faciliter le passage de l'élément d'application.The invention makes it possible to use as a wiper member, if desired, a wiper member which deforms relatively little, if not substantially when it is traversed by the applicator element and in particular a wiper member. spinning made of a non-cellular material, for example a polyolefin such as low density polyethylene or an elastomer, so that the wiper member can be relatively inexpensive to manufacture and easy to install on the container. Where appropriate, the wiper member may comprise one or more slots to facilitate the passage of the applicator element.

Avantageusement, l'élément d'application est floqué sur au moins une partie de sa surface servant à l'application, et ses branches peuvent notamment être entièrement floquées.Advantageously, the applicator element is flocked on at least a portion of its surface for application, and its branches can in particular be fully flocked.

La cavité peut déboucher ou non à l'extérieur. Lorsque la cavité débouche à l'extérieur, elle peut déboucher par un ou plusieurs ajours. La cavité peut par exemple déboucher au moins sur une face de l'élément d'application servant à l'application du produit. La cavité peut encore déboucher sur deux faces opposées de l'élément d'application, dont l'une au moins sert à l'application du produit. La cavité peut encore déboucher par plusieurs passages pour le produit, par exemple au moins trois passages équi-répartis angulairement autour d'un axe longitudinal de l'élément d'application.The cavity may or may not open to the outside. When the cavity opens out, it can lead to one or more openings. The cavity may for example lead to at least one face of the application element used for the application of the product. The cavity can still lead to two opposite faces of the application element, at least one of which serves for the application of the product. The cavity can still lead to several passes for the product, for example at least three equi-angularly distributed passages about a longitudinal axis of the application element.

Il peut être avantageux que la cavité débouche à l'extérieur car cela peut faciliter le dépôt du produit contenu dans la cavité sur la région traitée.It may be advantageous for the cavity to open out as this may facilitate the deposition of the product contained in the cavity on the treated region.

L'élément d'application peut comporter au moins une membrane souple adjacente à la cavité, la souplesse de cette membrane n'empêchant pas l'élément d'application de se déformer au passage de l'ouverture du récipient. La cavité peut par exemple être située entre deux membranes souples, reliant les branches. La membrane peut être ajourée ou non. L'élément d'application peut par exemple comporter une grille souple s'étendant au moins partiellement dans la cavité.The applicator element may comprise at least one flexible membrane adjacent to the cavity, the flexibility of this membrane does not prevent the applicator element from deforming as it passes through the opening of the container. The cavity may for example be located between two flexible membranes, connecting the branches. The membrane may be perforated or not. The application element may for example comprise a flexible grid extending at least partially in the cavity.

Avant tout contact de l'élément d'application avec le produit, la cavité peut être vide, c'est-à-dire remplie d'air. En variante, la cavité peut être au moins partiellement remplie d'un matériau élastiquement déformable, notamment un matériau présentant une déformabilité supérieure à celle de la portion de l'élément d'application définissant la cavité, notamment une déformabilité supérieure aux branches, par exemple une mousse de faible densité, un feutre ou un flocage.Before any contact of the application element with the product, the cavity may be empty, that is to say filled with air. As a variant, the cavity may be at least partially filled with an elastically deformable material, in particular a material having a deformability greater than that of the portion of the application element defining the cavity, notably a deformability greater than the branches, for example low density foam, felt or flocking.

L'élément d'application peut comporter plusieurs cavités.The application element may have several cavities.

La cavité peut présenter, dans un plan au moins, un contour fermé. L'élément d'application peut présenter une épaisseur de matière autour de la cavité, au moins dans un plan, qui est non constante. L'élément d'application peut encore présenter une épaisseur de matière autour de la cavité qui est sensiblement constante, au moins dans un plan.The cavity may have, in one plane at least, a closed contour. The applicator element may have a thickness of material around the cavity, at least in one plane, which is non-constant. The application member may further have a thickness of material around the cavity that is substantially constant, at least in one plane.

La cavité peut par exemple s'étendre sur plus de la moitié de la largeur de l'élément d'application. La cavité peut s'étendre sur plus de la moitié de la longueur de l'élément d'application.The cavity may for example extend over more than half the width of the applicator element. The cavity may extend over more than half the length of the applicator element.

Dans des exemples de mise en oeuvre de l'invention, la variation de la plus grande dimension transversale de l'élément d'application à la traversée de l'ouverture du récipient est supérieure ou égale à 20 %, mieux supérieure ou égale à 40 %, voire plus encore.In exemplary embodiments of the invention, the variation of the greatest transverse dimension of the applicator element through the opening of the container is greater than or equal to 20%, better still greater than or equal to 40 % or more.

L'élément d'application peut comporter un corps en un matériau thermoplastique, définissant la cavité, et ce corps peut être au moins partiellement recouvert par un flocage, voire être entièrement floqué.The applicator element may comprise a body made of a thermoplastic material, defining the cavity, and this body may be at least partially covered by a flocking, or even be entirely flocked.

L'élément d'application peut être dépourvu de métal, ce qui autorise par exemple son passage dans un four à micro-ondes.The application element may be devoid of metal, which allows for example its passage in a microwave oven.

La forme de l'élément d'application pourra dépendre notamment de la région du corps ou du visage sur laquelle le produit doit être appliqué.The shape of the application element may depend in particular on the region of the body or face on which the product is to be applied.

Pour les lèvres par exemple, la cavité peut avantageusement s'étendre sensiblement parallèlement à un plan formant un angle non nul avec l'axe longitudinal d'une tige à laquelle l'élément d'application se raccorde. Une portion au moins de l'élément d'application peut ainsi être allongée selon un axe longitudinal qui forme un angle non nul avec l'axe longitudinal de la tige de support. L'axe longitudinal de l'élément d'application peut encore être sensiblement coaxial à celui de la tige qui porte l'élément d'application.For lips for example, the cavity may advantageously extend substantially parallel to a plane forming a non-zero angle with the longitudinal axis of a rod to which the applicator element is connected. At least a portion of the applicator element can thus be elongated along a longitudinal axis that forms a non-zero angle with the longitudinal axis of the support rod. The longitudinal axis of the applicator element may be substantially coaxial with that of the rod which carries the applicator element.

L'élément d'application peut présenter une surface enveloppe symétrique de révolution ou non. L'élément d'application peut présenter une forme symétrique relativement à un plan médian, notamment un plan médian contenant l'axe longitudinal de la tige de support. Cette dernière peut être reliée à l'extrémité opposée à celle portant l'élément d'application à un capuchon de fermeture du récipient.The application element may have a symmetrical envelope surface of revolution or not. The applicator element may have a symmetrical shape relative to a median plane, in particular a median plane containing the longitudinal axis of the support rod. The latter can be connected to the end opposite to that carrying the applicator element to a closing cap of the container.

Dans des exemples de mise en oeuvre de l'invention, l'élément d'application est dépourvu de dents ou picots de forme allongée.In exemplary embodiments of the invention, the applicator element does not have elongate teeth or pins.

Le récipient peut comporter, comme mentionné plus haut, un organe d'essorage rapporté, lequel est par exemple fixé dans le col du récipient. En variante, le récipient est dépourvu d'organe d'essorage. Une plus petite section transversale de l'ouverture du récipient peut être circulaire, que le récipient comporte ou non un organe d'essorage rapporté.The container may comprise, as mentioned above, an attached wiper member, which is for example fixed in the neck of the container. In a variant, the container does not have a wiper member. A smaller cross section of the opening of the container may be circular, whether or not the container has an added wiper.

La fixation de l'élément d'application sur la tige peut s'effectuer de diverses manières et l'élément d'application peut notamment comporter un embout de fixation engagé dans la tige. L'élément d'application peut comporter un embout serti dans la tige ou encliqueté dans ou sur celle-ci. Plutôt que d'être rapporté sur la tige, l'élément d'application peut encore être réalisé au moins partiellement d'un seul tenant avec la tige.Fixation of the applicator element on the rod can be carried out in various ways and the application element can include a fastening tip engaged in the rod. The applicator element may comprise a tip crimped into the rod or snapped in or on it. Rather than being attached to the rod, the application element can be made at least partially in one piece with the rod.

Dans d'autres exemples de mise en oeuvre de l'invention, l'élément d'application comporte un corps filiforme ayant deux extrémités engagées dans la tige.In other examples of implementation of the invention, the applicator element comprises a filiform body having two ends engaged in the rod.

La tige peut présenter un diamètre extérieur supérieur ou égal à 2,5 mm, mieux supérieur ou égal à 3 mm, notamment de l'ordre de 4 mm environ, ce qui lui confère une certaine rigidité et peut accroître la précision du maquillage.The rod may have an outer diameter greater than or equal to 2.5 mm, better than or equal to 3 mm, in particular of the order of about 4 mm, which gives it a certain rigidity and can increase the precision of the makeup.

L'invention a encore pour objet, selon un autre de ses aspects, l'applicateur considéré isolément, indépendamment de l'organe d'essorage qui lui est éventuellement associé. Un tel applicateur est par exemple associé à une réserve de produit qui n'est pas nécessairement contenue dans un récipient comportant un col au travers duquel l'applicateur doit être introduit. La réserve de produit est par exemple une masse de produit sous forme de pain, éventuellement contenue dans une coupelle.The invention further relates, in another of its aspects, the applicator considered in isolation, independently of the wiper member which is possibly associated with it. Such an applicator is for example associated with a reserve of product that is not necessarily contained in a container having a neck through which the applicator must be introduced. The product reserve is for example a mass of product in the form of bread, possibly contained in a cup.

L'invention a encore pour objet, selon un autre de ses aspects, un dispositif de conditionnement et d'application d'un produit sur la peau, les muqueuses, les ongles ou les fibres kératiniques, comportant :

  • un récipient contenant le produit à appliquer, ce récipient présentant une ouverture,
  • un applicateur comportant une tige et un élément d'application à une extrémité de la tige, l'élément d'application étant allongé selon un axe longitudinal et présentant une plus grande dimension transversale,

l'élément d'application comportant au moins deux branches se rapprochant l'une de l'autre en se déplaçant dans la direction de la plus grande dimension transversale lorsque l'élément d'application franchit l'ouverture du récipient.Another subject of the invention, according to another of its aspects, is a device for packaging and applying a product to the skin, mucous membranes, nails or keratin fibers, comprising:
  • a container containing the product to be applied, this container having an opening,
  • an applicator comprising a rod and an applicator element at one end of the rod, the applicator element being elongated along a longitudinal axis and having a larger transverse dimension,

the applicator element having at least two branches approaching each other moving in the direction of the greatest transverse dimension when the applicator element passes through the opening of the container.

Le déplacement des deux branches en rapprochement l'une de l'autre peut s'effectuer par exemple sur plus d'un dixième de la plus grande dimension transversale, voire plus d'un huitième ou d'un cinquième. Les deux branches qui se rapprochent peuvent se toucher ou non lors du franchissement de l'ouverture du récipient. Les deux branches peuvent délimiter entre elles une cavité qui est vide ou non. Les deux portions peuvent s'étendre selon un plan qui fait ou non un angle avec l'axe longitudinal de la tige. Les deux branches peuvent être dépourvues de dents ou de picots, étant par exemple lisses ou floquées, notamment lorsque l'applicateur est destiné à appliquer un produit sur la peau ou les lèvres.The movement of the two branches towards each other can be performed for example on more than one tenth of the largest transverse dimension, or more than one eighth or fifth. The two branches that come closer can touch or not when crossing the opening of the container. The two branches can delimit between them a cavity which is empty or not. The two portions may extend in a plane which is or is not an angle with the longitudinal axis of the rod. The two branches may be devoid of teeth or pins, being for example smooth or flocked, especially when the applicator is intended to apply a product on the skin or lips.

Les deux branches de l'élément d'application peuvent présenter des formes différentes.The two branches of the application element may have different shapes.

L'une des branches est par exemple plus épaisse, ce qui peut permettre de décentrer la cavité. La cavité peut être unique.One of the branches is for example thicker, which may allow to decenter the cavity. The cavity can be unique.

La cavité peut présenter une forme relativement allongée, avec un rapport m/n par exemple supérieur ou égal à 3, ou 4, ou 5 ou 6, où m désigne la longueur de la cavité et n sa plus grande largeur.The cavity may have a relatively elongated shape, with an m / n ratio for example greater than or equal to 3, or 4, or 5 or 6, where m denotes the length of the cavity and n its widest width.

La largeur de la cavité peut passer par un extremum entre ses deux extrémités libres, cet extremum étant par exemple un maximum.The width of the cavity may pass through an extremum between its two free ends, this extremum being for example a maximum.

Les branches peuvent présenter un bord extérieur longitudinal convexe vers l'extérieur, ou concave vers l'extérieur, ou sensiblement rectiligne sur une fraction au moins de sa longueur, par exemple à mi-longueur environ.The branches may have a longitudinal outer edge convex outwardly, or concave outwards, or substantially rectilinear over a fraction at least of its length, for example about halfway length.

Le bord extérieur d'au moins l'une des branches peut être au moins partiellement strié.The outer edge of at least one of the branches may be at least partially streaked.

Les branches peuvent être floquées au moins partiellement.The branches can be flocked at least partially.

L'élément d'application peut comporter des poils de flocage présentant des longueurs différentes, avec par exemple des poils plus long à proximité de l'extrémité distale de l'élément d'application.The applicator element may include flocking bristles having different lengths, for example with longer bristles near the distal end of the applicator element.

Les branches peuvent présenter, en section transversale, une forme circulaire, oblongue, par exemple elliptique, polygonale, à sommets arrondis ou non, par exemple triangulaire, carrée ou rectangulaire. Les branches peuvent être creuses.The branches may have, in cross section, a circular shape, oblong, for example elliptical, polygonal, with rounded or not rounded tops, for example triangular, square or rectangular. The branches can be hollow.

Les branches sont par exemple réalisées dans un élastomère, notamment un élastomère thermoplastique.The branches are for example made of an elastomer, in particular a thermoplastic elastomer.

L'invention a encore pour objet, selon un autre de ses aspects, un dispositif pour appliquer un produit sur la peau, les muqueuses ou les ongles, comportant :

  • un récipient contenant le produit à appliquer,
  • un applicateur pour appliquer le produit, cet applicateur comportant :
    • une tige,
    • un élément d'application à une extrémité de la tige,
      l'élément d'application comportant :
      • deux portions latérales,
      • des portions proximale et distale réunissant les portions latérales,
      • une cavité définie entre les portions latérales, distale et proximale,
      • un flocage recouvrant au moins partiellement les portions latérales, proximale et distale.
The invention further relates, in another of its aspects, to a device for applying a product to the skin, the mucous membranes or the nails, comprising:
  • a container containing the product to be applied,
  • an applicator for applying the product, this applicator comprising:
    • a rod,
    • an application element at one end of the rod,
      the application element comprising:
      • two side portions,
      • proximal and distal portions joining the lateral portions,
      • a cavity defined between the lateral, distal and proximal portions,
      • flocking at least partially covering the lateral, proximal and distal portions.

Les portions latérales peuvent présenter des axes longitudinaux qui s'étendent sensiblement parallèlement à un même plan, lequel peut faire un angle avec l'axe longitudinal de la tige. Les axes longitudinaux peuvent converger l'un vers l'autre en direction de la portion distale. La portion proximale peut comporter des bords adjacents à la tige qui s'étendent obliquement relativement à l'axe longitudinal de celle-ci. Les portions latérales, proximale et distale peuvent définir entre elles une cavité qui est vide.The lateral portions may have longitudinal axes that extend substantially parallel to the same plane, which may be at an angle to the longitudinal axis of the rod. The longitudinal axes can converge towards each other in the direction of the distal portion. The proximal portion may have edges adjacent to the stem that extend obliquely relative to the longitudinal axis thereof. The lateral, proximal and distal portions may define between them a cavity which is empty.

L'élément d'application peut comporter un embout engagé à l'intérieur de la tige. Celle-ci peut présenter, dans le cas où sa section est circulaire, un diamètre extérieur sensiblement constant, au moins pour sa portion introduite dans le récipient au contact du produit.The application element may comprise a tip engaged inside the rod. This may have, in the case where its section is circular, a substantially constant outside diameter, at least for its portion introduced into the container in contact with the product.

Les portions latérales, proximale et distale peuvent être réalisées en matière thermoplastique par moulage par injection, notamment un élastomère thermoplastique.The lateral, proximal and distal portions may be made of thermoplastic material by injection molding, in particular a thermoplastic elastomer.

L'applicateur peut comporter, à une extrémité de la tige opposée à l'élément d'application, un capuchon de fermeture du récipient.The applicator may comprise, at one end of the rod opposite the applicator element, a cap for closing the container.

Selon cet aspect de l'invention, l'élément d'application peut se déformer ou non entre le moment où il se charge de produit et celui où le produit est appliqué.According to this aspect of the invention, the applicator element may or may not deform between the moment when it is loaded with product and the one where the product is applied.

Le dispositif 1 de conditionnement et d'application représenté à la figure 1 comporte un récipient 2 contenant un produit P à appliquer et un applicateur 3 comportant une tige 4 d'axe longitudinal X, munie à une première extrémité d'un élément de préhension 5 constituant également un capuchon de fermeture étanche du récipient 2 et à l'autre extrémité d'un élément d'application 6.The device 1 for packaging and application shown in Figure 1 comprises a container 2 containing a product P to be applied and an applicator 3 having a rod 4 of longitudinal axis X, provided at one end with a gripping element 5 also constituting a sealing cap of the container 2 and at the other end of an applicator element 6.

Dans l'exemple illustré, l'axe X de la tige 4 est rectiligne mais il pourrait être courbe, en variante.In the illustrated example, the axis X of the rod 4 is rectilinear but it could be curved, alternatively.

Le récipient 2 est pourvu en partie supérieure d'un col 7 dans lequel est engagé un organe d'essorage 8.The container 2 is provided in the upper part with a neck 7 in which is engaged a wiper member 8.

L'élément de préhension 5 se visse sur le col 7 mais pourrait en variante se fixer autrement, par encliquetage par exemple.The gripping element 5 is screwed on the neck 7 but could alternatively be fixed differently, for example by snapping.

Comme on peut le voir plus particulièrement sur la figure 6, l'organe d'essorage 8 comporte une collerette 9 en appui sur la tranche supérieure du col 7 et une lèvre d'essorage 10 définissant dans l'exemple considéré un orifice d'essorage 11 de section circulaire, de diamètre a, par exemple sensiblement égal à celui de la tige 4. Cette dernière présente un diamètre généralement supérieur à 2,5 mm, par exemple de l'ordre de 4 mm.As can be seen more particularly in FIG. 6, the wiper member 8 comprises a flange 9 resting on the upper edge of the neck 7 and a wiper lip 10 defining in the example under consideration a wringing orifice. 11 of circular section, of diameter a , for example substantially equal to that of the rod 4. The latter has a diameter generally greater than 2.5 mm, for example of the order of 4 mm.

L'organe d'essorage 8 est réalisé dans l'exemple illustré dans une matière non alvéolaire, par exemple une polyoléfme ou un élastomère. La polyoléfine est par exemple du polyéthylène, notamment basse ou haute densité.The wiper member 8 is made in the example shown in a non-cellular material, for example a polyolefin or an elastomer. The polyolefin is for example polyethylene, especially low or high density.

Dans l'exemple de la figure 1, la surface extérieure de l'élément d'application 6 est floquée. Dans d'autres exemples de réalisation, l'élément d'application 6 pourrait par exemple ne pas être floqué ou comporter au moins partiellement en surface un revêtement autre qu'un flocage, par exemple un tissé, un non-tissé, une mousse ou présenter des reliefs, par exemple un quadrillage.In the example of Figure 1, the outer surface of the applicator element 6 is flocked. In other exemplary embodiments, the applicator element 6 could for example not be flocked or at least partially surface-covered with a coating other than flocking, for example a woven fabric, a nonwoven fabric, a foam or present reliefs, for example a grid.

Dans l'exemple illustré, l'élément d'application 6 présente, comme on peut le voir sur la figure 5, une forme générale symétrique par rapport à un plan médian de symétrie M et comporte une cavité 12 qui est délimitée latéralement par deux portions latérales ou branches 13 et axialement par des portions distale 14 et proximale 15 réunissant les branches 13. Ces dernières sont allongées selon des axes longitudinaux respectifs Y qui s'étendent sensiblement parallèlement à un plan B, comme on peut le voir sur la figure 4, lequel fait avec l'axe X de la tige 4 un angle α qui est par exemple compris entre environ 20° et environ 30°. L'angle β entre chaque axe Y et le plan médian de symétrie M est par exemple compris entre 5 et 45°, comme on peut le voir sur la figure 2.In the example illustrated, the application element 6 has, as can be seen in FIG. 5, a general shape symmetrical with respect to a median plane of symmetry M and comprises a cavity 12 which is delimited laterally by two portions. lateral or branches 13 and axially by distal portions 14 and proximal 15 joining the branches 13. The latter are elongated along respective longitudinal axes Y which extend substantially parallel to a plane B, as can be seen in Figure 4, which makes with the axis X of the rod 4 an angle α which is for example between about 20 ° and about 30 °. The angle β between each Y axis and the median plane of symmetry M is for example between 5 and 45 °, as can be seen in FIG.

La forme des portions distale 14 et proximale 15 sera avantageusement choisie de manière à faciliter le franchissement de l'ouverture 11 du récipient 2. La portion proximale 15 peut ainsi comporter des bords 60, adjacents à la tige 4, s'étendant obliquement relativement à l'axe X, et la portion distale 14 peut présenter une forme générale effilée.The shape of the distal 14 and proximal portions 15 will advantageously be chosen so as to facilitate the crossing of the opening 11 of the container 2. The proximal portion 15 may thus comprise edges 60, adjacent to the stem 4, extending obliquely relative to the X axis, and the distal portion 14 may have a generally tapered shape.

Dans l'exemple considéré, les branches 13 convergent l'une vers l'autre en direction de la portion distale 14 et la cavité 12 présente, lorsque l'élément d'application 6 est observé en élévation, une forme sensiblement triangulaire.In the example considered, the branches 13 converge towards each other towards the distal portion 14 and the cavity 12 has, when the application element 6 is observed in elevation, a substantially triangular shape.

La cavité 12 s'étend par exemple, comme on peut le voir sur la figure 5 notamment, sur plus du quart de la largeur b de l'élément d'application 6 ainsi que sur plus du quart de sa longueur l. Les dimensions de la cavité 12 peuvent être choisies en fonction de la déformabilité nécessaire pour franchir l'ouverture 11 du récipient et de la quantité de produit que l'on souhaite voir retenue éventuellement, par capillarité notamment, dans la cavité 12 après retrait de l'applicateur du récipient.The cavity 12 extends for example, as can be seen in Figure 5 in particular, over more than a quarter of the width b of the applicator element 6 and more than a quarter of its length l . The dimensions of the cavity 12 may be chosen as a function of the deformability required to cross the opening 11 of the container and the amount of product that it is desired to retain optionally, particularly by capillarity, in the cavity 12 after removal of the applicator of the container.

La largeur b de l'élément d'application 6 est supérieure au plus petit diamètre a de l'organe d'essorage 8, de telle sorte qu'à la traversée de celui-ci l'élément d'application 6 se déforme, comme illustré sur les figures 7 à 10.The width b of the application element 6 is greater than the smallest diameter a of the wiper member 8, so that, when the wiper member 8 passes through it, the applicator element 6 deforms, as illustrated in Figures 7 to 10.

En particulier, on peut voir sur ces figures que les portions latérales 13 se rapprochent l'une de l'autre sensiblement parallèlement à la direction D de la plus grande dimension transversale, au point que leurs faces en regard peuvent se toucher, la forme de la cavité 12 étant modifiée lors de la traversée de l'organe d'essorage 8 par l'élément d'application 6.In particular, it can be seen in these figures that the lateral portions 13 approach each other substantially parallel to the direction D of the largest transverse dimension, to the point that their facing faces can touch each other, the shape of the cavity 12 being modified during the passage of the wiper member 8 by the applicator element 6.

Le rapport b/a est par exemple supérieur à 1,2, voire 1,4 ou 1,6, de sorte que la variation subie par la plus grande dimension transversale de l'élément d'application à la traversée de l'ouverture 11 peut être sensible. La largeur b est par exemple de l'ordre de 9 mm et la dimension a de l'ordre de 4 mm.The ratio b / a is for example greater than 1.2, or even 1.4 or 1.6, so that the variation experienced by the greatest transverse dimension of the applicator element through the opening 11 can be sensitive. The width b is for example of the order of 9 mm and the dimension has of the order of 4 mm.

La partie la plus large de l'élément d'application 6 est de préférence celle qui est la plus flexible.The widest part of the application element 6 is preferably the one that is the most flexible.

Après traversée de l'ouverture 11 du récipient, l'élément d'application 6 peut reprendre grâce à son élasticité propre sa forme initiale, comme on le voit sur la figure 10.After passing through the opening 11 of the container, the application element 6 can resume its own elasticity its original shape, as seen in Figure 10.

On peut observer sur la figure 11 que du produit P peut être chassé de la cavité 12 lors de la traversée de l'organe d'essorage 8, lorsque les portions latérales 13 se rapprochent. Dans l'exemple considéré, des espaces 63 subsistent néanmoins de part et d'autre de l'élément d'application 6 lorsque les branches 13 se sont rapprochées, et le produit P peut s'étendre dans ces espaces 63. Lorsque les branches 13 s'écartent à nouveau, le produit P peut retourner dans la cavité 12. La présence des espaces 63 permet d'éviter un essorage trop poussé de l'élément d'application 6, à sa traversée de l'organe d'essorage 8.It can be seen in FIG. 11 that product P can be driven out of cavity 12 as it passes through wiper member 8 when side portions 13 approach each other. In the example considered, spaces 63 nevertheless remain on either side of the applicator element 6 when the branches 13 have approached each other, and the product P can extend into these spaces 63. deviate again, the product P can return to the cavity 12. The presence of spaces 63 allows to avoid excessive spinning of the applicator element 6, as it passes through the wiper member 8.

Le produit P présent dans la cavité 12 accroît l'autonomie de l'applicateur et peut améliorer également le confort à l'application, en facilitant le glissement de l'applicateur sur la surface traitée.The product P present in the cavity 12 increases the autonomy of the applicator and can also improve comfort on application, facilitating the sliding of the applicator on the treated surface.

Le produit P est par exemple destiné à être appliqué sur les lèvres et l'utilisateur peut le déposer sur celles-ci en amenant par exemple la face arrière 20 de l'élément d'application 6 à leur contact, comme illustré à la figure 12. Dans l'exemple considéré, la face arrière 20 correspond à celle qui est située du côté arrière lorsque l'élément d'application 6 est observé avec les portions latérales 13 s'étendant vers l'avant.The product P is for example intended to be applied to the lips and the user can deposit it on them by bringing for example the rear face 20 of the applicator element 6 to their contact, as shown in FIG. 12 In the example considered, the rear face 20 corresponds to that located on the rear side when the application element 6 is observed with the lateral portions 13 extending forward.

Lors de l'application, suivant la surface de l'élément d'application 6 en contact avec la zone traitée, l'épaisseur de produit déposée pourra être différente, ce qui peut permettre à l'utilisateur de faire varier par exemple la brillance du maquillage.During the application, depending on the surface of the applicator element 6 in contact with the treated zone, the deposited product thickness may be different, which may allow the user to vary, for example, the brightness of the makeup.

Lorsque l'élément d'application 6 est appliqué à plat, le produit P présent dans la cavité 12 peut se déposer et la surface chargée de produit P venant au contact des lèvres peut être relativement importante, de sorte que les lèvres peuvent être maquillées assez rapidement.When the application element 6 is applied flat, the product P present in the cavity 12 can be deposited and the product-loaded surface P coming into contact with the lips can be relatively large, so that the lips can be made up sufficiently quickly.

Le cas échéant, l'application peut se faire seulement avec le bout de la portion distale 14, pour dessiner un contour par exemple.If necessary, the application can be made only with the end of the distal portion 14, to draw an outline for example.

Dans le cas où l'on souhaite essorer plus vigoureusement la tige 4 et l'élément d'application 6, l'organe d'essorage 8 peut être réalisé avec un diamètre plus faible. On peut alors réaliser si nécessaire la tige 4 avec un rétreint 40, comme illustré sur la figure 13, ce rétreint 40 évitant de solliciter mécaniquement l'organe d'essorage 8 lorsque le récipient est fermé.In the case where it is desired to wring more vigorously the rod 4 and the application member 6, the wiper member 8 can be made with a smaller diameter. If necessary, the rod 4 can be made with a necking 40, as shown in FIG. 13, this necking 40 avoiding mechanically biasing the wiper member 8 when the container is closed.

Le dispositif 1 peut encore être réalisé sans organe d'essorage rapporté dans le col 7 du récipient, comme illustré à la figure 14. Sur cette figure, on voit que le col 7 peut présenter un plus petit diamètre intérieur a qui est plus faible que la largeur b de l'élément d'application 6, de telle sorte que l'élément d'application 6 se déforme à la traversée de l'ouverture 11 du récipient.The device 1 can also be produced without added wiper member in the neck 7 of the container, as shown in Figure 14. In this figure, it can be seen that the neck 7 may have a smaller internal diameter a which is smaller than the width b of the applicator element 6, so that the applicator element 6 deforms as it passes through the opening 11 of the container.

Dans une variante non illustrée, le récipient 2 est réalisé avec un organe d'essorage surmoulé.In a variant not shown, the container 2 is made with an overmoulded wringing member.

On a illustré à la figure 15 la possibilité d'utiliser un organe d'essorage 8 rapporté, autre que celui représenté à la figure 1.FIG. 15 illustrates the possibility of using an attached wiper member 8, other than that shown in FIG. 1.

Sur la figure 15, l'organe d'essorage 8 est constitué par un bloc d'un matériau alvéolaire, élastiquement compressible.In Figure 15, the wiper member 8 is constituted by a block of a cellular material, elastically compressible.

L'organe d'essorage 8 peut être traversé en son centre par un évidement 42 définissant l'ouverture 11 du récipient, comme on peut le voir sur la figure 16.The wiper member 8 may be traversed at its center by a recess 42 defining the opening 11 of the container, as can be seen in FIG.

Le diamètre de l'évidement 42 peut par exemple correspondre sensiblement à celui de la tige 4.The diameter of the recess 42 may for example correspond substantially to that of the rod 4.

L'organe d'essorage peut encore, quelle que soit sa nature, alvéolaire ou non, avoir une ou plusieurs fentes, lesquelles peuvent être à bords jointifs ou non.The wiper member may still, regardless of its nature, alveolar or not, have one or more slots, which may be contiguous edges or not.

L'applicateur peut être utilisé en association avec un essoreur à fente. A titre d'exemple, on a représenté à la figure 42 un organe d'essorage 8 comportant une ouverture centrale pour le passage de la tige et de l'élément d'application et plusieurs fentes 100, lesquelles peuvent être radiales.The applicator can be used in combination with a slotted wiper. For example, there is shown in Figure 42 a wiper member 8 having a central opening for the passage of the rod and the application member and several slots 100, which may be radial.

La fixation de l'élément d'application 6 sur la tige 4 peut s'effectuer par divers moyens.Fixing the application element 6 on the rod 4 can be effected by various means.

Dans l'exemple de la figure 1, la portion proximale 15 est prolongée, comme on peut le voir sur la figure 5, par un embout 18 engagé à l'intérieur de la tige 4.In the example of FIG. 1, the proximal portion 15 is extended, as can be seen in FIG. 5, by a tip 18 engaged inside the rod 4.

Cet embout 18 est par exemple collé, agrafé ou soudé dans la tige 4. Cette dernière peut encore être sertie sur l'embout, comme illustré sur la figure 17.This tip 18 is for example glued, stapled or welded in the rod 4. The latter can be crimped onto the tip, as shown in Figure 17.

La figure 18 illustre la possibilité de solidariser l'élément d'application et la tige par encliquetage. L'embout 18 est par exemple configuré pour s'encliqueter sur une tête 70 réalisée à l'extrémité de la tige 4. Le diamètre extérieur de l'embout 18 peut alors, par exemple, correspondre sensiblement à celui de la tige 4.Figure 18 illustrates the possibility of securing the application element and the rod snap. The tip 18 is for example configured to snap onto a head 70 made at the end of the rod 4. The outer diameter of the tip 18 may then, for example, correspond substantially to that of the rod 4.

Dans une variante non illustrée, c'est la tige 4 qui est encliquetée sur l'embout 18.In a variant not shown, it is the rod 4 which is snapped onto the endpiece 18.

Le corps de l'élément d'application peut encore être réalisé d'une seule pièce avec la tige 4, comme illustré sur la figure 19.The body of the applicator element can also be made in one piece with the rod 4, as illustrated in FIG. 19.

On a illustré à la figure 20 la possibilité pour au moins une portion de l'élément d'application 6 de s'étendre selon un axe longitudinal Z qui fait un angle γ avec l'axe longitudinal X de la tige 4, les axes X et Z étant contenus dans un même plan et la cavité 12 s'étendant sensiblement parallèlement à ce plan.FIG. 20 illustrates the possibility for at least a portion of the application element 6 to extend along a longitudinal axis Z which makes an angle γ with the longitudinal axis X of the rod 4, the X axes and Z being contained in the same plane and the cavity 12 extending substantially parallel to this plane.

On a illustré sur la figure 21 la possibilité pour l'élément d'application 6 de présenter une forme non symétrique par rapport à l'axe X de la tige 4. Le cas échéant, comme illustré à la figure 22, l'élément d'application 6 peut présenter un bord 72 s'étendant sensiblement dans l'alignement de la tige 4.FIG. 21 illustrates the possibility for the applicator element 6 to have a non-symmetrical shape with respect to the axis X of the rod 4. Where appropriate, as illustrated in FIG. 6 may have an edge 72 extending substantially in alignment with the rod 4.

L'élément d'application 6 peut encore comporter plus d'une cavité 12, par exemple deux cavités 12 ainsi que représenté à la figure 23.The application element 6 may also comprise more than one cavity 12, for example two cavities 12 as shown in FIG. 23.

Les deux cavités 12 sont par exemple alignées selon l'axe longitudinal de l'élément d'application 6. Ce dernier peut présenter par exemple, en vue de face, la forme générale d'un huit.The two cavities 12 are for example aligned along the longitudinal axis of the applicator element 6. The latter may have, for example, in front view, the general shape of an eight.

Dans l'exemple de la figure 1, l'élément d'application 6 s'étend obliquement relativement à l'axe longitudinal X de la tige 4.In the example of FIG. 1, the application element 6 extends obliquely with respect to the longitudinal axis X of the rod 4.

L'élément d'application 6 peut encore être allongé, dans une variante non illustrée, selon un axe longitudinal curviligne.The applicator element 6 can be further extended, in a non-illustrated variant, along a curvilinear longitudinal axis.

L'élément d'application 6 peut être réalisé autrement et chaque branche 13 peut par exemple s'étendre avec son axe longitudinal Y contenu dans un plan qui est parallèle à l'axe longitudinal X de la tige 4, comme illustré sur la figure 24.The application element 6 may be made differently and each branch 13 may for example extend with its longitudinal axis Y contained in a plane which is parallel to the longitudinal axis X of the rod 4, as illustrated in FIG. 24 .

Dans l'exemple de la figure 1 notamment, la cavité 12 débouche à l'avant et à l'arrière de l'élément d'application 6, lorsque celui-ci est observé de face, comme sur la figure 2.In the example of Figure 1 in particular, the cavity 12 opens at the front and rear of the application element 6, when it is viewed from the front, as in Figure 2.

On ne sort pas du cadre de la présente invention lorsque la cavité 12 débouche à l'extérieur autrement, voire est complètement enfermée dans l'élément d'application 6, comme illustré aux figures 25 et 26. Dans une telle variante de réalisation, l'élément d'application 6 peut présenter une surface enveloppe sensiblement symétrique de révolution autour de son axe longitudinal. La surface enveloppe peut encore avoir une forme autre, notamment lorsque l'élément d'application 6 présente une section transversale ovale, comme illustré à la figure 27.It is not beyond the scope of the present invention when the cavity 12 opens out to the outside otherwise, or is completely enclosed in the applicator element 6, as illustrated in FIGS. 25 and 26. In such an alternative embodiment, the application element 6 may have a substantially symmetrical envelope surface of revolution about its longitudinal axis. The envelope surface may have another shape, especially when the applicator element 6 has an oval cross section, as shown in FIG. 27.

Dans l'exemple de la figure 28, l'élément d'application 6 comporte plus de deux portions intermédiaires 13 joignant les portions proximale 15 et distale 14. Les portions intermédiaires 13 sont par exemple au nombre de trois ou quatre et sont disposées autour de la cavité 12, laquelle débouche à l'extérieur par des ouvertures formées entre les portions intermédiaires 13. Ces dernières présentent par exemple une forme arquée, concave vers l'intérieur.In the example of FIG. 28, the applicator element 6 comprises more than two intermediate portions 13 joining the proximal and distal portions 14. The intermediate portions 13 are for example three or four in number and are arranged around the cavity 12, which opens out through openings formed between the intermediate portions 13. The latter have for example an arched shape, concave inwardly.

On a représenté sur les figures 29 et 30 un élément d'application 6 qui est formé par un corps filiforme 30, plein ou creux, ayant deux extrémités 31 et 32 engagées dans des logements correspondants de la tige 4.FIGS. 29 and 30 show an application element 6 which is formed by a filamentary body 30, solid or hollow, having two ends 31 and 32 engaged in corresponding housings of the rod 4.

On a illustré sur la figure 311a possibilité de réaliser l'élément d'application 6 avec une épaisseur de matière non constante autour de la cavité 12, dans un plan au moins. Sur cette figure, on voit que l'épaisseur de matière peut varier d'une épaisseur maximale e1 à une épaisseur minimale e2, par exemple au niveau des branches 13.FIG. 311a illustrates the possibility of producing the application element 6 with a non-constant thickness of material around the cavity 12, in at least one plane. In this figure, it can be seen that the thickness of material may vary from a maximum thickness e 1 to a minimum thickness e 2 , for example at the level of the branches 13.

Les branches 13 peuvent présenter, sur au moins une portion de leur longueur, une section transversale pleine, de forme circulaire par exemple.The branches 13 may have, over at least a portion of their length, a solid cross section, of circular shape for example.

On a illustré sur la figure 32 la possibilité pour les branches 13 de présenter une forme autre en section, avec par exemple des faces en regard 77 sensiblement planes.FIG. 32 illustrates the possibility for the branches 13 to present a shape other in section, with, for example, facing faces 77 substantially planar.

Dans une variante non illustrée, les branches 13 sont creuses.In a variant not shown, the branches 13 are hollow.

Dans les exemples qui viennent d'être décrits, la cavité 12 est remplie d'air avant tout contact de l'élément d'application 6 avec le produit contenu dans le récipient. Il pourrait en être autrement.In the examples which have just been described, the cavity 12 is filled with air before any contact of the application element 6 with the product contained in the container. It could be otherwise.

Ainsi, la cavité 12 peut par exemple être au moins partiellement occupée par le flocage s'étendant sur le corps de l'élément d'application 6, comme c'est le cas dans l'exemple illustré à la figure 37. Les poils du flocage recouvrant le corps de l'élément d'application 6 peuvent par exemple être suffisamment longs pour que les poils situés sur les faces en regard des branches 13 se rencontrent.Thus, the cavity 12 may for example be at least partially occupied by the flocking extending over the body of the applicator element 6, as is the case in the example illustrated in FIG. 37. flocking covering the body of the application element 6 may for example be long enough for the bristles located on the facing faces of the branches 13 meet.

On a illustré sur les figures 37A à 37E la possibilité pour les branches 13 de présenter diverses formes en section, par exemple sensiblement polygonale, notamment triangulaire, comme représenté à la figure 37A ou carrée comme représenté à la figure 37D, aplatie sensiblement parallèlement au plan de la cavité 12 comme représenté à la figure 37B, ou encore aplatie et orientée obliquement de façon à ce que la cavité 12 débouche extérieurement par deux ouvertures inégales comme illustré à la figure 37C.FIGS. 37A to 37E illustrate the possibility for the branches 13 to have various shapes in section, for example substantially polygonal, in particular triangular, as shown in FIG. 37A or square as shown in FIG. 37D, flattened substantially parallel to the plane of the cavity 12 as shown in Figure 37B, or flattened and oriented obliquely so that the cavity 12 opens outwardly through two unequal openings as shown in Figure 37C.

Quelle que soit leur section, les branches 13 peuvent par exemple présenter une hauteur h qui est supérieure à la largeur w de la cavité 12 entre les branches, comme illustré à la figure 37E.Whatever their section, the branches 13 may for example have a height h which is greater than the width w of the cavity 12 between the branches, as shown in Figure 37E.

L'élément d'application 6 peut, comme illustré à la figure 33, comporter deux cavités 12 qui sont séparées par une membrane souple 80 réunissant les branches 13 et située par exemple à mi-épaisseur de celles-ci.The applicator element 6 may, as illustrated in FIG. 33, comprise two cavities 12 which are separated by a flexible membrane 80 joining the branches 13 and situated for example at mid-thickness thereof.

Cette membrane 80 peut être floquée ou non. Sa souplesse n'empêche pas l'élément d'application 6 de se déformer suffisamment pour franchir l'ouverture du récipient, si nécessaire. La membrane 80 peut être remplacée par une grille 81, comme illustré à la figure 40. La cavité 12 peut ne déboucher que sur une face de l'élément d'application 6, comme illustré à la figure 34, l'élément d'application pouvant comporter une membrane 82 définissant par exemple au moins partiellement la surface d'application par sa face extérieure 83. Cette membrane 82 peut par exemple être floquée extérieurement. Dans une variante non illustrée, au moins un orifice permet à du produit contenu dans la cavité 12 de gagner la face extérieure 83, à travers la membrane 82.This membrane 80 may be flocked or not. Its flexibility does not prevent the application element 6 to deform sufficiently to cross the opening of the container, if necessary. The membrane 80 may be replaced by a grid 81, as shown in FIG. 40. The cavity 12 may only open on one face of the application element 6, as illustrated in FIG. 34, the application element may comprise a membrane 82 defining for example at least partially the application surface by its outer face 83. This membrane 82 may for example be flocked externally. In a variant not shown, at least one orifice allows the product contained in the cavity 12 to gain the outer face 83, through the membrane 82.

Les membranes 80 ou 82 peuvent être moulées d'un seul tenant avec les branches 13.The membranes 80 or 82 may be molded in one piece with the branches 13.

La membrane 82 peut être remplacée par une membrane 84 rapportée, comme illustré sur la figure 35. La membrane 84 peut par exemple comporter un tissé ou un non-tissé, une mousse, un film perforé, une grille, un feutre, entre autres, et peut être fixée par soudage ou collage, par exemple.The membrane 82 may be replaced by an attached membrane 84, as illustrated in FIG. 35. The membrane 84 may for example comprise a woven or a nonwoven, a foam, a perforated film, a grid, a felt, among others. and can be fixed by welding or gluing, for example.

La membrane 84 peut être perméable ou non au produit P contenu dans la cavité 12.The membrane 84 may be permeable or not to the product P contained in the cavity 12.

Dans l'exemple de la figure 36, la cavité 12 est formée entre deux membranes souples 86, lesquelles peuvent par exemple réunir les branches 13.In the example of FIG. 36, the cavity 12 is formed between two flexible membranes 86, which can, for example, join the branches 13.

Les membranes 86 peuvent être rapportées sur le reste de l'élément d'application ou en variante être réalisées d'un seul tenant avec le corps de celui-ci. Les membranes 86 peuvent être ou non perméables au produit P.The membranes 86 may be attached to the remainder of the applicator element or alternatively may be made integral with the body thereof. The membranes 86 may or may not be permeable to the product P.

Dans les exemples des figures 33 à 36, les membranes 80, 82, 84 ou 86 peuvent être ou non élastiquement déformables.In the examples of FIGS. 33 to 36, the membranes 80, 82, 84 or 86 may or may not be elastically deformable.

La cavité 12 peut encore être au moins partiellement remplie, comme on peut le voir sur les figures 38 et 39, par un matériau 43 n'empêchant pas outre mesure la déformation de l'élément d'application 6 à la traversée de l'ouverture du récipient, quand cela est nécessaire. Le matériau 43 peut par exemple être une mousse de faible densité, à cellules très ouvertes, plus facilement déformable que le corps de l'élément d'application 6 entourant la cavité 12. Le matériau 43 peut, le cas échéant, être floqué extérieurement, comme on le voit sur la figure 39. L'une au moins de ses faces extérieures 90 peut défmir au moins partiellement la surface d'application.The cavity 12 may also be at least partially filled, as can be seen in FIGS. 38 and 39, by a material 43 that does not excessively prevent the deformation of the application element 6 at the crossing of the opening of the container, when necessary. The material 43 may for example be a low-density foam, with very open cells, more easily deformable than the body of the applicator element 6 surrounding the cavity 12. The material 43 may, if appropriate, be flocked externally, as can be seen in FIG. 39. At least one of its outer faces 90 can at least partially deflect the application surface.

Le corps de l'élément d'application 6 est par exemple réalisé au moins partiellement par moulage par injection dans une matière thermoplastique, par exemple du PVC, PU, EVA, SIS-SEB, nitrile, silicone, EPDM, Hytrel®, Pebax®, Santoprene®, ou d'autres thermoplastiques, élastomères.The body of the application element 6 is for example made at least partially by injection molding in a thermoplastic material, for example PVC, PU, EVA, SIS-SEB, nitrile, silicone, EPDM, Hytrel®, Pebax® , Santoprene®, or other thermoplastics, elastomers.

L'élément d'application 6 peut encore être réalisé dans des matières non thermoplastiques, par exemple des résines souples, ou être réalisé autrement que par moulage, par exemple par découpage, comme illustré à la figure 41.The applicator element 6 may also be made of non-thermoplastic materials, for example flexible resins, or be made other than by molding, for example by cutting, as illustrated in FIG. 41.

On a représenté aux figures 43 et 44 un élément d'application 6 qui présente des faces supérieure 130 et inférieure 131 qui convergent en direction de l'extrémité distale de l'élément d'application, au moins le long d'une portion de la cavité 12.FIGS. 43 and 44 show an application element 6 which has upper and lower faces 131 which converge towards the distal end of the applicator element, at least along a portion of the cavity 12.

L'axe longitudinal X de la tige 4 est par exemple sensiblement parallèle à l'une de ces faces, par exemple la face supérieure 130.The longitudinal axis X of the rod 4 is for example substantially parallel to one of these faces, for example the upper face 130.

Dans cet exemple, l'élément d'application 6 présente également, lorsqu'observé de dessus comme représenté à la figure 44, des bords longitudinaux sensiblement rectilignes qui convergent vers l'extrémité distale.In this example, the application element 6 also has, when viewed from above as shown in Figure 44, substantially rectilinear longitudinal edges which converge towards the distal end.

Les éléments d'application représentés sur les figures 45 à 61 peuvent avantageusement être utilisés pour l'application d'un produit, de maquillage ou de soin, sur les fibres kératiniques, par exemple les cils ou les sourcils.The application elements shown in Figures 45 to 61 may advantageously be used for the application of a product, makeup or care, on keratin fibers, for example eyelashes or eyebrows.

Dans ces éléments d'application, la cavité 12, unique, présente une forme allongée, le rapport de la longueur m de la cavité à la plus grande largeur n de celle-ci étant par exemple supérieur ou égal à 3, ou 4, ou 5 ou 6. On a par exemple 3 ≤ m/n ≤ 6.In these application elements, the single cavity 12 has an elongated shape, the ratio of the length m of the cavity to the greatest width n thereof being, for example, greater than or equal to 3, or 4, or 5 or 6. For example, there is 3 ≤ m / n ≤ 6.

La figure 45 représente un élément d'application dont la cavité 12 présente une largeur sensiblement constante sur au moins la moitié de sa longueur. Les bords longitudinaux des branches 13 sont rectilignes et parallèles entre eux, de part et d'autre d'une portion médiane située à mi-longueur de la cavité.FIG. 45 represents an application element whose cavity 12 has a substantially constant width over at least half of its length. The longitudinal edges of the branches 13 are rectilinear and parallel to each other, on either side of a median portion located mid-length of the cavity.

Dans l'exemple de la figure 46, l'élément d'application 6 est floqué et sa portion distale est recouverte par des poils plus longs que ceux recouvrant les branches 13. Cette portion distale sert par exemple à maquiller le coin de l'oeil.In the example of FIG. 46, the applicator element 6 is flocked and its distal portion is covered by bristles longer than those covering the branches 13. This distal portion serves, for example, to make up the corner of the eye. .

Dans l'exemple de la figure 47, les branches 13 présentent des largeurs inégales et la cavité 12 est décentrée.In the example of Figure 47, the branches 13 have unequal widths and the cavity 12 is off-center.

Dans l'exemple de la figure 48, les bords longitudinaux des branches 13 apparaissent striés, lorsque l'élément d'application est observé de dessus.In the example of Figure 48, the longitudinal edges of the branches 13 appear streaked, when the application element is observed from above.

La figure 49 illustre la possibilité pour les branches 13 de l'élément d'application de présenter des bords longitudinaux concaves vers l'extérieur. La cavité peut alors présenter une largeur passant par un minimum entre ses deux extrémités axiales.Figure 49 illustrates the possibility for the branches 13 of the application element to have concave longitudinal edges outwardly. The cavity may then have a width passing through a minimum between its two axial ends.

Dans l'exemple de la figure 50, les bords longitudinaux des branches sont convexes vers l'extérieur, et la cavité 12 présente lorsqu'observée de dessus une forme lenticulaire.In the example of Figure 50, the longitudinal edges of the branches are convex outwardly, and the cavity 12 has when viewed from above a lenticular shape.

L'élément d'application représenté à la figure 51 présente un axe longitudinal Y curviligne et l'extrémité libre de l'élément d'application ne se situe pas sur l'axe longitudinal X de la tige. L'une des branches présente un bord extérieur convexe vers l'extérieur et l'autre branche un bord extérieur concave vers l'extérieur.The application element represented in FIG. 51 has a curvilinear longitudinal axis Y and the free end of the applicator element is not situated on the longitudinal axis X of the rod. One of the branches has an outwardly convex outer edge and the other branches an outwardly concave outer edge.

L'élément d'application de la figure 52 présente une branche ayant un bord extérieur convexe vers l'extérieur et une autre branche ayant un bord extérieur rectiligne. De plus, on peut voir sur cette figure que la cavité 12 peut être relativement étroite et former une fente capillaire.The applicator element of Figure 52 has a branch having an outwardly convex outer edge and another branch having a straight outer edge. In addition, it can be seen in this figure that the cavity 12 can be relatively narrow and form a capillary slot.

Dans l'exemple de réalisation de la figure 53, la cavité 12 est plus large que dans l'exemple de la figure 52 et présente une largeur variable, passant par un extremum.In the embodiment of Figure 53, the cavity 12 is wider than in the example of Figure 52 and has a variable width, passing through an extremum.

La figure 54 illustre la possibilité pour l'élément d'application de comporter deux branches dont l'une présente un bord extérieur rectiligne et l'autre un bord extérieur concave vers l'extérieur.FIG. 54 illustrates the possibility for the applicator element to comprise two branches, one of which has a rectilinear outer edge and the other a concave outer edge towards the outside.

Dans l'exemple de la figure 55, l'élément d'application présente un axe longitudinal curviligne, comme dans l'exemple de la figure 51, et l'extrémité libre de l'élément d'application est située du même côté, relativement à l'axe longitudinal X de la tige, que pratiquement tout le reste de l'élément d'application.In the example of FIG. 55, the applicator element has a curvilinear longitudinal axis, as in the example of FIG. 51, and the free end of the applicator element is located on the same side, relatively to the longitudinal axis X of the rod, that virtually all the rest of the application element.

La figure 56 illustre la possibilité pour l'une des branches de l'élément d'application de présenter des rainures tandis que l'autre branche en est dépourvue. Ces rainures s'étendent par exemple transversalement à la branche.Figure 56 illustrates the possibility for one of the branches of the application element to have grooves while the other branch is devoid of it. These grooves extend for example transversely to the branch.

Les figures 57 et 59 représentent des éléments d'application comportant une troisième branche 16 qui joint les portions distale et proximale de l'élément d'application.Figures 57 and 59 show application members having a third limb 16 joining the distal and proximal portions of the applicator member.

Dans l'exemple de la figure 57, la troisième branche est située d'un côté du plan défmi par les axes longitudinaux des deux branches 13, comme on peut le voir sur la figure 58. La troisième branche 16 présente par exemple une forme arquée.In the example of FIG. 57, the third branch is located on one side of the plane defined by the longitudinal axes of the two branches 13, as can be seen in FIG. 58. The third branch 16 has, for example, an arcuate shape. .

Dans l'exemple de la figure 59, les deux premières branches 13 et la troisième branche 16 sont disposées de manière régulière autour de l'axe longitudinal Y de l'élément d'application, la portion proximale de l'élément d'application ayant une section transversale généralement en forme de triangle ou d'étoile à trois branches, comme on peut le voir sur la figure 60.In the example of FIG. 59, the first two branches 13 and the third branch 16 are arranged regularly around the longitudinal axis Y of the application element, the proximal portion of the application element having a cross-section generally in the shape of a triangle or a star with three branches, as can be seen in FIG.

On a illustré à la figure 61 la possibilité de réaliser le corps de l'élément d'application de manière monolithique avec la tige et avec l'organe de préhension, qui peut également servir d'organe de fermeture du récipient.FIG. 61 illustrates the possibility of making the body of the applicator element monolithic with the rod and with the gripping member, which can also serve as a closure member for the container.

Les éléments d'application des figures 45 à 61 sont par exemple réalisés au moins partiellement par moulage de matière, notamment une matière thermoplastique.The application elements of Figures 45 to 61 are for example made at least partially by molding material, including a thermoplastic material.

Les éléments d'application des figures 45 à 61 peuvent permettre de charger les cils avec une quantité relativement importante de produit. Deux branches de l'élément d'application peuvent être utilisées simultanément ou successivement pour appliquer du produit sur les cils.The application elements of Figures 45 to 61 can be used to load the eyelashes with a relatively large amount of product. Two branches of the application element can be used simultaneously or successively to apply the product on the eyelashes.

Pour tous les éléments d'application précédemment décrits, l'application du produit pourra le cas échéant s'effectuer de diverses manières selon le résultat recherché, l'élément d'application étant par exemple utilisé à plat, sur la tranche ou avec diverses inclinaisons, l'orientation choisie permettant à l'utilisateur de contrôler par exemple l'intensité du maquillage.For all the application elements described above, the application of the product may optionally be carried out in various ways depending on the desired result, the application element being for example used flat, on the edge or with various inclinations , the chosen orientation allowing the user to control for example the intensity of makeup.

L'élément d'application peut présenter des formes autres que celles illustrées, par exemple en losange, en cercle ou en ellipse lorsque l'élément d'application est observé de face.The application element may have shapes other than those illustrated, for example diamond, circle or ellipse when the application element is observed from the front.

Les éléments d'application peuvent comporter des particules magnétiques.The application elements may comprise magnetic particles.

Lorsque l'élément d'application est déformable, sa déformabilité peut être mise à profit pour récupérer du produit qui adhère à la surface intérieure du récipient.When the applicator element is deformable, its deformability can be used to recover product that adheres to the inner surface of the container.

Un élément d'application présentant une forme nettement allongée, comme c'est le cas par exemple des éléments d'application des figures 45 à 61, est avantageusement réalisé de manière à permettre cette déformation.An application element having a clearly elongated shape, as is the case for example of the application elements of Figures 45 to 61, is advantageously designed to allow this deformation.

Bien entendu, l'invention n'est pas limitée aux exemples de réalisation qui viennent d'être décrits. On peut notamment combiner entre elles les caractéristiques des différents exemples de réalisation.Of course, the invention is not limited to the embodiments which have just been described. In particular, the characteristics of the different exemplary embodiments can be combined with one another.

Tous les éléments d'application décrits plus haut, notamment ceux décrits en référence au dessin, peuvent encore être utilisés selon un autre aspect de l'invention sans qu'une déformation de l'élément d'application n'intervienne entre le chargement en produit et l'application, ce qui peut être le cas par exemple lorsque ces éléments d'application sont utilisés en association avec une réserve de produit contenue ailleurs que dans un récipient pourvu d'un col.All the application elements described above, in particular those described with reference to the drawing, can still be used according to another aspect of the invention without a deformation of the application element intervenes between the product loading. and the application, which may be the case for example when these application elements are used in combination with a reserve of product contained elsewhere than in a container provided with a neck.

Dans de tels exemples de mise en oeuvre de l'invention, la tige de l'applicateur peut être dépourvue de l'élément de préhension 5.In such exemplary embodiments of the invention, the rod of the applicator may be devoid of the gripping element 5.

Le produit P est par exemple contenu, sous la forme d'une pâte, d'une poudre compactée ou d'une poudre libre ou autrement, dans une coupelle d'un boîtier 110, comme illustré à la figure 62.The product P is for example contained, in the form of a paste, a compacted powder or a loose powder or otherwise, in a cup of a housing 110, as illustrated in FIG. 62.

L'applicateur est par exemple reçu dans un logement correspondant 112 du boîtier.The applicator is for example received in a corresponding housing 112 of the housing.

L'élément d'application peut être chargé en produit en étant amené au contact de celui-ci. Une déformation de l'élément d'application peut avoir lieu ou non au moment où le produit est prélevé.The application element can be loaded into product by being brought into contact with it. Deformation of the application element may or may not occur at the moment the product is taken.

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.
