Description

La présente invention concerne un applicateur de produit cosmétique selon le préambule de la revendication 1.The present invention relates to a cosmetic product applicator according to the preamble of claim 1.

L'applicateur est destiné à ouvrir le récipient contenant le produit cosmétique et à délivrer le produit cosmétique contenu de manière étanche dans le récipient sur une surface corporelle de l'utilisateur, avantageusement une surface kératinique telle que les cheveux.The applicator is intended to open the container containing the cosmetic product and to deliver the cosmetic product contained tightly in the container on a body surface of the user, preferably a keratinous surface such as the hair.

US 5 297 882 A , US 5 343 880 A et EP 0 353 001 A décrivent des exemples d'applicateurs de produits cosmétiques. US 5,297,882 A , US 5,343,880 A and EP 0 353 001 A describe examples of applicators of cosmetic products.

Le produit cosmétique est par exemple un produit de soin des fibres kératiniques. Plus généralement, le produit cosmétique peut être un produit de coloration des fibres kératiniques, un produit nettoyant, un produit solaire ou encore un produit de maquillage.The cosmetic product is for example a care product for keratinous fibers. More generally, the cosmetic product may be a product for coloring keratin fibers, a cleaning product, a solar product or a make-up product.

Par « produit cosmétique », on entend avantageusement au sens de la présente invention, un produit tel que défini dans le Règlement (CE) N°1222/2009 du Parlement Européen et du Conseil, daté du 30 novembre 2009, relatif aux produits cosmétiques.For the purposes of the present invention, the term "cosmetic product" advantageously means a product as defined in Regulation (EC) No. 1222/2009 of the European Parliament and of the Council, dated November 30, 2009, relating to cosmetic products.

Dans le domaine cosmétique, certains produits doivent être conditionnés de manière étanche dans un récipient afin d'être conservés pendant une longue durée. Puis, juste avant l'application du produit, le récipient est ouvert pour permettre la délivrance du produit.In the cosmetic field, certain products must be sealed in a container in order to be stored for a long time. Then, just before application of the product, the container is opened to allow delivery of the product.

Ceci est le cas par exemple pour les doses de produits destinés à empêcher la chute des cheveux, qui sont appliquées de façon espacée dans le temps.This is the case for example for the doses of products intended to prevent hair loss, which are applied spacially in time.

Pour faciliter l'application du produit sur la surface corporelle, il est connu de FR 2 854 140 de conditionner le produit dans un récipient muni d'un opercule frangible et de prévoir un applicateur du type précité, qui comporte un corps tubulaire propre à être vissé sur le récipient.To facilitate the application of the product to the body surface, it is known to FR 2,854,140 packaging the product in a container provided with a frangible lid and provide an applicator of the aforementioned type, which comprises a tubular body clean to be screwed on the container.

L'applicateur est muni d'une lame qui déchire l'opercule lors de la rotation de l'applicateur pendant son vissage sur le récipient.The applicator is provided with a blade that tears the lid during the rotation of the applicator during its screwing on the container.

Un tel applicateur fonctionne de manière satisfaisante lorsque l'orientation relative du récipient et de l'applicateur est bien contrôlée.Such an applicator works satisfactorily when the relative orientation of the container and the applicator is well controlled.

Cet applicateur peut cependant être encore amélioré pour faciliter la gestuelle d'utilisation, et notamment pour tenir compte d'éventuels défauts d'orientation du récipient lors de son montage dans l'applicateur.This applicator can, however, be further improved to facilitate the use of gestures, and in particular to take into account any orientation defects of the container when it is mounted in the applicator.

Un but de l'invention est donc d'obtenir un applicateur propre à être monté sur un récipient contenant de manière étanche du produit cosmétique, pour ouvrir le récipient et délivrer le produit avec une gestuelle rapide, fiable et aisée.An object of the invention is therefore to obtain a clean applicator to be mounted on a container sealingly containing the cosmetic product, to open the container and deliver the product with a quick gesture, reliable and easy.

Dans tout ce qui suit, les termes « amont » et « aval » s'entendent généralement par rapport au sens normal de circulation d'un fluide.In what follows, the terms "upstream" and "downstream" generally refer to the normal direction of circulation of a fluid.

Un premier nécessaire 10 de distribution de produit cosmétique selon l'invention est illustré par les figures 1 et 2.A first cosmetic product dispensing kit 10 according to the invention is illustrated by the Figures 1 and 2 .

Le produit cosmétique distribué par le nécessaire 10 selon l'invention est par exemple un produit de soin des fibres kératiniques, tel qu'un produit empêchant la chute des cheveux. Plus généralement, le produit cosmétique peut être un produit de coloration des fibres kératiniques, un produit nettoyant, un produit solaire ou encore un produit de maquillage.The cosmetic product dispensed by the kit 10 according to the invention is, for example, a care product for keratin fibers, such as a product that prevents hair loss. More generally, the cosmetic product may be a product for coloring keratin fibers, a cleaning product, a solar product or a make-up product.

Comme représenté sur la figure 1, le nécessaire 10 comprend un récipient 12 recevant de manière étanche une dose 13 d'un produit cosmétique, et un applicateur 14, destiné à être monté sur le récipient 12 pour ouvrir le récipient 12 et distribuer le produit cosmétique sur une surface corporelle d'un utilisateur.As shown on the figure 1 , the kit 10 comprises a container 12 sealingly receiving a dose 13 of a cosmetic product, and an applicator 14, intended to be mounted on the container 12 to open the container 12 and to dispense the cosmetic product onto a body surface of an user.

La surface corporelle est par exemple située sur une ou plusieurs fibres kératiniques de l'utilisateur, ou sur la peau dans une zone comprenant des fibres kératiniques.The body surface is for example located on one or more keratin fibers of the user, or on the skin in an area comprising keratinous fibers.

En référence aux figures 2, 5 et 6, le récipient 12 comporte une paroi creuse 16 délimitant un volume intérieur 18 de réception du produit cosmétique, et un opercule frangible 20 obturant de manière étanche la paroi creuse 16.With reference to Figures 2, 5 and 6 , the container 12 has a hollow wall 16 delimiting an interior volume 18 for receiving the cosmetic product, and a frangible cap 20 sealingly sealing the hollow wall 16.

Dans cet exemple, la paroi creuse 16 est de forme généralement allongée et cylindrique suivant un axe A-A' représenté vertical sur la figure 5. La paroi creuse 16 comporte ainsi une cloison latérale 22 sensiblement cylindrique et un fond 24. Elle délimite une ouverture supérieure couverte par l'opercule 20.In this example, the hollow wall 16 is of generally elongate and cylindrical shape along an axis AA 'represented vertically on the figure 5 . The hollow wall 16 thus comprises a substantially cylindrical lateral partition 22 and a bottom 24. It delimits an upper opening covered by the cover 20.

Le volume intérieur 18 du récipient 12 est par exemple inférieur à 100 ml, et est avantageusement compris entre 1 ml et 10 ml.The internal volume 18 of the container 12 is for example less than 100 ml, and is advantageously between 1 ml and 10 ml.

L'opercule 20 est avantageusement réalisé à base d'un matériau plus souple que la paroi creuse 16. Il comporte une paroi aval 26 frangible et une jupe extérieure 28 de fixation sur la paroi creuse 16.The cover 20 is advantageously made from a softer material than the hollow wall 16. It comprises a frangible downstream wall 26 and an outer fixing skirt 28 on the hollow wall 16.

Le fond 24 présente un épaulement 24A sensiblement de même diamètre extérieur que la jupe 28 de l'opercule 20. Cet épaulement, en combinaison avec un godron 24B sur la cloison latérale 22 (visible sur la figure 5), permet de stabiliser les récipients 12 lors de leur remplissage sur ligne de production. En outre, l'épaulement 24A du fond 24 permet une préhension améliorée du récipient par un utilisateur lorsque le récipient 12 est inséré dans l'applicateur.The bottom 24 has a shoulder 24A of substantially the same external diameter as the skirt 28 of the lid 20. This shoulder, in combination with a godron 24B on the side wall 22 (visible on the figure 5 ), makes it possible to stabilize the containers 12 during their filling on the production line. In addition, the shoulder 24A of the bottom 24 allows an improved grip of the container by a user when the container 12 is inserted into the applicator.

L'opercule 20 comporte en outre de préférence une jupe intérieure 30 d'étanchéité insérée dans le volume intérieur 18 pour obturer de manière étanche ce volume 18.The seal 20 also preferably comprises an inner sealing skirt 30 inserted into the interior volume 18 to seal this volume 18 in a sealed manner.

La paroi aval 26 s'étend transversalement par rapport à l'axe A-A'. Elle présente une ligne de rupture préférentielle 32 visible en détail sur la figure 6.The downstream wall 26 extends transversely with respect to the axis A-A '. It has a preferential rupture line 32 visible in detail on the figure 6 .

La ligne de rupture 32 est par exemple formée par une région amincie de la paroi aval 26. Elle peut être interne ou externe à la paroi aval 26The rupture line 32 is for example formed by a thinned region of the downstream wall 26. It may be internal or external to the downstream wall 26

Comme illustré par la figure 6, la ligne de rupture 32 comporte au moins un tronçon circonférentiel 34, avantageusement de révolution autour de l'axe A-A' et au des fibres kératiniques, un produit nettoyant, un produit solaire ou encore un produit de maquillage.As illustrated by figure 6 , the rupture line 32 comprises at least one circumferential section 34, advantageously of revolution about the axis AA 'and at keratin fibers, a cleaning product, a solar product or a makeup product.

Comme représenté sur la figure 1, le nécessaire 10 comprend un récipient 12 recevant de manière étanche une dose 13 d'un produit cosmétique, et un applicateur 14, destiné à être monté sur le récipient 12 pour ouvrir le récipient 12 et distribuer le produit cosmétique sur une surface corporelle d'un utilisateur.As shown on the figure 1 , the kit 10 comprises a container 12 sealingly receiving a dose 13 of a cosmetic product, and an applicator 14, intended to be mounted on the container 12 to open the container 12 and to dispense the cosmetic product onto a body surface of an user.

La surface corporelle est par exemple située sur une ou plusieurs fibres kératiniques de l'utilisateur, ou sur la peau dans une zone comprenant des fibres kératiniques.The body surface is for example located on one or more keratin fibers of the user, or on the skin in an area comprising keratinous fibers.

En référence aux figures 2, 5 et 6, le récipient 12 comporte une paroi creuse 16 délimitant un volume intérieur 18 de réception du produit cosmétique, et un opercule frangible 20 obturant de manière étanche la paroi creuse 16.With reference to Figures 2, 5 and 6 , the container 12 has a hollow wall 16 delimiting an interior volume 18 for receiving the cosmetic product, and a frangible cap 20 sealingly sealing the hollow wall 16.

Dans cet exemple, la paroi creuse 16 est de forme généralement allongée et cylindrique suivant un axe A-A' représenté vertical sur la figure 5. La paroi creuse 16 comporte ainsi une cloison latérale 22 sensiblement cylindrique et un fond 24. Elle délimite une ouverture supérieure couverte par l'opercule 20.In this example, the hollow wall 16 is of generally elongate and cylindrical shape along an axis AA 'represented vertically on the figure 5 . The hollow wall 16 thus comprises a substantially cylindrical lateral partition 22 and a bottom 24. It delimits an upper opening covered by the cover 20.

Le volume intérieur 18 du récipient 12 est par exemple inférieur à 100 ml, et est avantageusement compris entre 1 ml et 10 ml.The internal volume 18 of the container 12 is for example less than 100 ml, and is advantageously between 1 ml and 10 ml.

L'opercule 20 est avantageusement réalisé à base d'un matériau plus souple que la paroi creuse 16. Il comporte une paroi aval 26 frangible et une jupe extérieure 28 de fixation sur la paroi creuse 16.The cover 20 is advantageously made from a softer material than the hollow wall 16. It comprises a frangible downstream wall 26 and an outer fixing skirt 28 on the hollow wall 16.

Le fond 24 présente un épaulement 24A sensiblement de même diamètre extérieur que la jupe 28 de l'opercule 20. Cet épaulement, en combinaison avec un godron 24B sur la cloison latérale 22 (visible sur la figure 5), permet de stabiliser les récipients 12 lors de leur remplissage sur ligne de production. En outre, l'épaulement 24A du fond 24 permet une préhension améliorée du récipient par un utilisateur lorsque le récipient 12 est inséré dans l'applicateur.The bottom 24 has a shoulder 24A of substantially the same external diameter as the skirt 28 of the lid 20. This shoulder, in combination with a godron 24B on the side wall 22 (visible on the figure 5 ), makes it possible to stabilize the containers 12 during their filling on the production line. In addition, the shoulder 24A of the bottom 24 allows an improved grip of the container by a user when the container 12 is inserted into the applicator.

L'opercule 20 comporte en outre de préférence une jupe intérieure 30 d'étanchéité insérée dans le volume intérieur 18 pour obturer de manière étanche ce volume 18.The seal 20 also preferably comprises an inner sealing skirt 30 inserted into the interior volume 18 to seal this volume 18 in a sealed manner.

La paroi aval 26 s'étend transversalement par rapport à l'axe A-A'. Elle présente une ligne de rupture préférentielle 32 visible en détail sur la figure 6.The downstream wall 26 extends transversely with respect to the axis A-A '. It has a preferential rupture line 32 visible in detail on the figure 6 .

La ligne de rupture 32 est par exemple formée par une région amincie de la paroi aval 26. Elle peut être interne ou externe à la paroi aval 26The rupture line 32 is for example formed by a thinned region of the downstream wall 26. It may be internal or external to the downstream wall 26

Comme illustré par la figure 6, la ligne de rupture 32 comporte au moins un tronçon circonférentiel 34, avantageusement de révolution autour de l'axe A-A' et au moins un tronçon radial 36 s'étendant radialement vers l'extérieur à partir du tronçon circonférentiel 34.As illustrated by figure 6 , the rupture line 32 comprises at least one circumferential section 34, advantageously of revolution about the axis AA 'and at at least one radial section 36 extending radially outwardly from the circumferential section 34.

De préférence, la ligne de rupture 32 comporte une pluralité de tronçons radiaux 36 espacés angulairement les uns des autres autour de l'axe A-A'.Preferably, the rupture line 32 comprises a plurality of radial sections 36 spaced angularly from each other about the axis A-A '.

Dans l'exemple représenté sur la figure 6, le tronçon circonférentiel 34 est circulaire et chaque tronçon radial 36 est linéaire. La ligne de rupture 32 présente ainsi une forme générale de soleil.In the example shown on the figure 6 the circumferential section 34 is circular and each radial section 36 is linear. The rupture line 32 thus has a general shape of sun.

Comme on le verra plus bas, la ligne de rupture 32 est propre à être partiellement rompue par l'applicateur 14 pour passer le récipient 12 d'une configuration fermée de conditionnement du produit cosmétique, à une configuration ouverte de distribution du produit cosmétique.As will be seen below, the rupture line 32 is able to be partially broken by the applicator 14 to pass the container 12 of a closed configuration of packaging of the cosmetic product to an open dispensing configuration of the cosmetic product.

La rupture partielle de la ligne 32 par l'applicateur 14 crée un volet central 38 délimité extérieurement par le tronçon circonférentiel 34 et une charnière 40 s'étendant entre deux tronçons radiaux 36 pour permettre l'articulation du volet central 38 par rapport à une région périphérique 42 de la paroi aval 26.The partial rupture of the line 32 by the applicator 14 creates a central flap 38 delimited externally by the circumferential section 34 and a hinge 40 extending between two radial sections 36 to allow articulation of the central flap 38 relative to a region peripheral 42 of the downstream wall 26.

Ainsi, le volet 38 ouvert par l'applicateur 14 reste solidaire de l'opercule 20 et ne tombe pas dans le fond du volume intérieur 18 dans la configuration ouverte.Thus, the flap 38 open by the applicator 14 remains integral with the lid 20 and does not fall into the bottom of the interior volume 18 in the open configuration.

Le récipient 12 définit une surface périphérique 44 extérieure d'étanchéité, destinée à s'appliquer contre une surface intérieure de l'applicateur 14 pour former un joint d'étanchéité.The container 12 defines an outer peripheral sealing surface 44, intended to be applied against an inner surface of the applicator 14 to form a seal.

Dans l'exemple représenté sur la figure 5, la surface périphérique extérieure 44 est de révolution autour de l'axe A-A'. Elle est avantageusement située sur la jupe extérieure 28 de l'opercule 20. En variante (non représentée), la surface périphérique extérieure 44 est située sur la paroi creuse 16.In the example shown on the figure 5 the outer peripheral surface 44 is of revolution about the axis A-A '. It is advantageously located on the outer skirt 28 of the cover 20. Alternatively (not shown), the outer peripheral surface 44 is located on the hollow wall 16.

Comme illustré par les figures 1 à 4, l'applicateur 14 comporte un corps creux 50 d'insertion et de guidage du récipient 12, définissant un axe B-B' d'insertion du récipient 12 et un embout 52 d'application de produit cosmétique faisant saillie en aval du corps creux 50.As illustrated by Figures 1 to 4 , the applicator 14 comprises a hollow body 50 for inserting and guiding the container 12, defining an insertion axis BB 'of the container 12 and a cosmetic product applying tip 52 projecting downstream of the hollow body 50.

L'applicateur 14 comporte en outre un organe 54 d'ouverture du récipient 12, propre à rompre l'opercule frangible 20, et un organe 56 de poussée du produit cosmétique libéré hors du récipient 12 en vue de sa distribution à travers l'embout 52.The applicator 14 further comprises a member 54 for opening the container 12, capable of breaking the frangible lid 20, and a member 56 for pushing the cosmetic product released from the container 12 for distribution through the mouthpiece 52.

Le corps creux 50 présente une forme générale tubulaire. Il s'étend de manière allongée suivant l'axe B-B'. Il définit intérieurement une chambre amont 58 d'insertion et de guidage du récipient 12 et une chambre aval 60 de collecte et de distribution du produit cosmétique extrait hors du récipient 12.The hollow body 50 has a generally tubular shape. It extends elongated along the axis B-B '. It internally defines an upstream chamber 58 for inserting and guiding the container 12 and a downstream chamber 60 for collecting and dispensing the cosmetic product extracted from the container 12.

Le corps creux 50 comporte ainsi une cheminée amont 62 sensiblement tubulaire et un conduit de distribution aval 64 raccordant la cheminée 62 à l'embout 52.The hollow body 50 thus comprises a substantially tubular upstream chimney 62 and a downstream distribution pipe 64 connecting the chimney 62 to the endpiece 52.

La cheminée 62 et le conduit aval 64 sont avantageusement réalisés d'un seul tenant en étant venus de matière.The chimney 62 and the downstream duct 64 are advantageously made in one piece by being made of material.

La chambre amont 58 s'étend dans la cheminée 62. Elle est délimitée en aval par un épaulement 66 de blocage du récipient 12 faisant saillie vers l'axe B-B'.The upstream chamber 58 extends into the chimney 62. It is delimited downstream by a shoulder 66 for locking the container 12 projecting towards the axis B-B '.

La chambre amont 58 débouche en amont par une ouverture axiale amont 68 destinée à l'insertion du récipient 12. Elle débouche avantageusement transversalement par une fenêtre latérale 70 destinée à rendre visible, depuis l'extérieur de l'applicateur 14, une surface extérieure du récipient 12.The upstream chamber 58 opens upstream by an upstream axial opening 68 intended for the insertion of the container 12. It advantageously opens transversely by a lateral window 70 intended to make visible, from the outside of the applicator 14, an outer surface of the container 12.

La chambre amont 58 présente une section transversale sensiblement constante en se déplaçant le long de l'axe B-B'. Le contour extérieur de cette section transversale est sensiblement conjugué au contour extérieur de la surface périphérique 44 du récipient 12.The upstream chamber 58 has a substantially constant cross section moving along the axis B-B '. The outer contour of this cross section is substantially conjugated to the outer contour of the peripheral surface 44 of the container 12.

La chambre amont 58 est délimitée par une surface intérieure 72 de la cheminée 62, de révolution autour de l'axe B-B'. Selon l'invention, la surface intérieure de guidage 72 est configurée pour autoriser un déplacement du récipient 12 dans le corps tubulaire 50 le long de l'axe d'insertion B-B', sans rotation autour de l'axe d'insertion B-B'.The upstream chamber 58 is delimited by an inner surface 72 of the chimney 62, of revolution about the axis B-B '. According to the invention, the inner guiding surface 72 is configured to allow displacement of the container 12 in the tubular body 50 along the insertion axis B-B ', without rotation about the insertion axis B -B.

Avantageusement, la surface intérieure de guidage 72 est dépourvue d'aspérités circonférentielles faisant saillie dans la chambre 58. En particulier, la surface intérieure de guidage 72 est dépourvue de filetage.Advantageously, the inner guiding surface 72 is devoid of circumferential asperities projecting into the chamber 58. In particular, the inner guiding surface 72 is devoid of threading.

Il est ainsi possible d'insérer le récipient 12 dans le corps creux 50 sans avoir à choisir une orientation angulaire initiale du récipient 12 par rapport au corps creux 50, en effectuant une simple translation du récipient 12 dans le corps creux 50 le long de l'axe B-B', sans rotation autour de cet axe.It is thus possible to insert the container 12 in the hollow body 50 without having to choose an initial angular orientation of the container 12 relative to the hollow body 50, by making a simple translation of the container 12 in the hollow body 50 along the 'B-B' axis, without rotation around this axis.

La surface intérieure 72 est pleine au voisinage de l'épaulement 66, avantageusement entre la fenêtre 70 et l'épaulement 66. Elle présente un contour intérieur conjuguée au contour extérieur de la surface périphérique 44.The inner surface 72 is solid in the vicinity of the shoulder 66, advantageously between the window 70 and the shoulder 66. It has an inner contour conjugated to the outer contour of the peripheral surface 44.

Ceci permet la réalisation d'une étanchéité périphérique entre le récipient 12 et le corps creux 50 lorsque le récipient 12 est inséré dans la chambre amont 58.This allows the realization of a peripheral seal between the container 12 and the hollow body 50 when the container 12 is inserted into the upstream chamber 58.

La chambre aval 60 est délimitée par une partie aval de la cheminée 62, par l'organe de poussée 56 et par le conduit aval de distribution 64.The downstream chamber 60 is delimited by a downstream part of the chimney 62, by the thrust member 56 and by the downstream distribution duct 64.

Elle débouche en aval du conduit de distribution 64 par une ouverture aval 74 de distribution s'ouvrant dans l'embout d'application 52.It opens downstream of the distribution duct 64 through a downstream distribution opening 74 opening in the applicator nozzle 52.

Dans cet exemple, la partie aval de la cheminée 62 présente une forme convergeant vers le conduit aval 64, de section transversale décroissante, en se déplaçant vers l'aval.In this example, the downstream portion of the chimney 62 has a shape converging towards the downstream duct 64, of decreasing cross-section, while moving downstream.

Par ailleurs, le conduit aval de distribution 64 présente une forme de tige. Il s'étend suivant un axe C-C' décentré par rapport à l'axe B-B'.In addition, the downstream distribution duct 64 has a rod shape. It extends along an axis C-C 'off-center with respect to the axis B-B'.

L'embout d'application 52 est rapporté sur le conduit aval 64, ou est formé directement sur ce conduit 64.The applicator tip 52 is attached to the downstream duct 64, or is formed directly on this duct 64.

Dans cet exemple, l'embout 52 comporte une jupe 76 coiffant le conduit aval 64 et une tête 78 arrondie, avantageusement sphérique, délimitant au moins un canal 80 de sortie de produit cosmétique raccordé à l'ouverture aval 74.In this example, the tip 52 comprises a skirt 76 covering the downstream duct 64 and a rounded, preferably spherical, head 78 defining at least one cosmetic product outlet channel 80 connected to the downstream opening 74.

L'embout 52 définit l'extrémité aval de l'applicateur 14.The tip 52 defines the downstream end of the applicator 14.

L'organe d'ouverture 54 du récipient 12 fait saillie dans la cheminée 62 à travers la chambre aval 60, et au moins en partie à travers la chambre amont 58, jusqu'à une extrémité libre 90.The opening member 54 of the container 12 protrudes into the chimney 62 through the downstream chamber 60, and at least partly through the upstream chamber 58, to a free end 90.

Dans cet exemple, l'organe d'ouverture 54 s'étend suivant l'axe B-B' ou parallèlement à cet axe. Il est avantageusement venu de matière avec la cheminée 62.In this example, the opening member 54 extends along the axis B-B 'or parallel to this axis. It is advantageously material with the chimney 62.

L'organe d'ouverture 54 comporte un membre longitudinal creux 92. Le membre creux 92 débouche au niveau de l'extrémité libre 90 dans la chambre amont 58 par un orifice amont 94 et débouche en aval au moins en partie dans la chambre aval 60 par un orifice aval 96.The opening member 54 has a hollow longitudinal member 92. The hollow member 92 opens at the free end 90 in the upstream chamber 58 through an upstream orifice 94 and opens downstream at least partially in the downstream chamber 60 by a downstream orifice 96.

L'organe 54 comporte en outre au moins une saillie extérieure 98 destinée à faciliter l'ouverture de l'opercule 20, visible sur la figure 4.The member 54 further comprises at least one outer projection 98 intended to facilitate the opening of the cap 20, visible on the figure 4 .

Le membre creux 92 définit une lumière interne axiale 100 de circulation de produit cosmétique débouchant par l'orifice amont 94 axialement à l'extrémité libre 90 et débouchant transversalement par l'orifice aval 96.The hollow member 92 defines an axial internal lumen 100 of cosmetic product flow opening through the upstream orifice 94 axially at the free end 90 and opening transversely through the downstream orifice 96.

L'orifice amont 94 s'ouvre axialement au niveau l'extrémité libre 90 dans la chambre amont 58.The upstream orifice 94 opens axially at the free end 90 in the upstream chamber 58.

L'orifice aval 96 débouche transversalement dans la chambre aval 60 et avantageusement en partie dans la chambre amont 98. Il est formé ici par une fente longitudinale ménagée dans la paroi du membre creux 92.The downstream orifice 96 opens transversely into the downstream chamber 60 and advantageously partly into the upstream chamber 98. It is formed here by a longitudinal slot formed in the wall of the hollow member 92.

Lorsque l'organe 54 a percé l'opercule 20 du récipient 12, le produit cosmétique présent dans le récipient 12 est propre à être extrait, avantageusement par capillarité, à travers l'orifice amont 94, puis à circuler dans la lumière 100 jusqu'à l'orifice aval 96 pour atteindre la chambre aval 60.When the member 54 has pierced the lid 20 of the container 12, the cosmetic product present in the container 12 is able to be extracted, advantageously by capillary action, through the upstream orifice 94, then to circulate in the light 100 until at the downstream port 96 to reach the downstream chamber 60.

Ainsi, même si le perçage de l'opercule 20 est imparfait, du produit cosmétique peut s'écouler librement hors du récipient 12 à travers l'organe 54 pour atteindre la chambre aval 60.Thus, even if the piercing of the lid 20 is imperfect, cosmetic product can flow freely from the container 12 through the member 54 to reach the downstream chamber 60.

L'extrémité libre 90 est biseautée pour présenter une forme pointue. Cette forme biseautée permet de décentrer l'effort appliqué sur l'opercule 20 pour faciliter la création du volet 38.The free end 90 is beveled to have a pointed shape. This beveled shape makes it possible to off-center the force applied on the cover 20 to facilitate the creation of the flap 38.

Dans cet exemple, l'organe d'ouverture 54 comporte une pluralité de saillies latérales 98 faisant saillie à partir du corps creux 92.In this example, the opening member 54 has a plurality of side projections 98 protruding from the hollow body 92.

Chaque saillie 98 est formée par une ailette longitudinale faisant saillie radialement à partir du membre creux 92. Avantageusement, la largeur de chaque saillie 98, prise radialement à partir du membre creux 92 est inférieure ou sensiblement égale à la largeur du membre creux 92.Each projection 98 is formed by a longitudinal fin projecting radially from the hollow member 92. Advantageously, the width of each projection 98, taken radially from the hollow member 92 is less than or substantially equal to the width of the hollow member 92.

Les saillies 98 sont aptes à faciliter la rupture de l'opercule 20, et notamment de la ligne de rupture 32, ainsi que l'écartement du volet 38 autour de la charnière 40 pour ouvrir le récipient 12.The projections 98 are able to facilitate the rupture of the seal 20, and in particular of the rupture line 32, as well as the separation of the flap 38 around the hinge 40 to open the container 12.

Dans cet exemple, l'organe de poussée 56 comporte une cloison 110 déformable au toucher. La cloison 110 est fixée dans une fenêtre aval 112 de la cheminée 62 pour délimiter au moins en partie la chambre aval 60.In this example, the thrust member 56 has a partition 110 deformable to the touch. The partition 110 is fixed in a downstream window 112 of the chimney 62 to delimit at least part of the downstream chamber 60.

La cloison 110 est par exemple formée à base d'élastomère. La cheminée 62 est par exemple surmoulée sur la cloison 110.The partition 110 is for example formed based on elastomer. The chimney 62 is for example overmolded on the partition 110.

Dans cet exemple, la cloison 110 délimite un trou traversant 114 d'égalisation de pression (visible sur la figure 1) pour rétablir la pression atmosphérique dans la chambre aval 60, après la distribution du produit cosmétique.In this example, the partition 110 delimits a through hole 114 of pressure equalization (visible on the figure 1 ) to restore the atmospheric pressure in the downstream chamber 60 after the distribution of the cosmetic product.

L'organe de poussée 56 est propre à être manoeuvré par un doigt d'un utilisateur, par pression sur la cloison 110, afin de réduire le volume de la chambre 60 et provoquer l'expulsion du produit cosmétique contenu dans la chambre 60 vers l'aval hors de l'applicateur 14 à travers l'embout 52.The pushing member 56 is adapted to be operated by a finger of a user, by pressure on the partition 110, in order to reduce the volume of the chamber 60 and cause the expulsion of the cosmetic product contained in the chamber 60 towards the chamber. downstream of the applicator 14 through the tip 52.

Le récipient 12 est mobile par rapport à l'applicateur 14 entre une position de repos (non représentée), dans laquelle il est disposé totalement à l'écart de l'applicateur 14 et une position d'ouverture de l'opercule frangible 20 et de distribution produit cosmétique, représentée sur la figure 2.The container 12 is movable relative to the applicator 14 between a rest position (not shown), in which it is disposed completely away from the applicator 14 and an opening position of the frangible cap 20 and cosmetic product distribution, represented on the figure 2 .

Le fonctionnement du nécessaire 10 selon l'invention va maintenant être décrit.The operation of the kit 10 according to the invention will now be described.

Initialement, le récipient 12 occupe sa position de repos.Initially, the container 12 occupies its rest position.

Dans cette position de repos, l'opercule 20 du récipient 12 obture le volume intérieur 18 de manière étanche. Le produit cosmétique contenu dans le volume intérieur 18 peut ainsi être conservé.In this rest position, the seal 20 of the container 12 closes the inner volume 18 in a sealed manner. The cosmetic product contained in the interior volume 18 can thus be preserved.

Puis, l'utilisateur saisit le récipient 12 et l'applicateur 14. Il introduit le récipient 12 par l'opercule 20 dans la chambre amont 58 à travers l'ouverture amont 68.Then, the user grasps the container 12 and the applicator 14. It introduces the container 12 through the lid 20 into the upstream chamber 58 through the upstream opening 68.

Il déplace ensuite le récipient 12 vers la chambre aval 60 en translation le long de l'axe d'insertion B-B', sans rotation autour de cet axe.It then moves the container 12 to the downstream chamber 60 in translation along the insertion axis B-B ', without rotation about this axis.

La surface périphérique extérieure 44 du récipient 12 est appliquée de manière étanche sur la surface périphérique intérieure 72 du corps creux 50. Le récipient 12 obture alors de manière étanche la chambre aval 60. Le passage de produit cosmétique hors de l'applicateur 14 autour du réservoir 12 est ainsi empêché.The outer peripheral surface 44 of the container 12 is sealingly applied to the inner peripheral surface 72 of the hollow body 50. The container 12 then seals the downstream chamber 60. The passage of cosmetic product from the applicator 14 around the reservoir 12 is thus prevented.

Lorsque l'extrémité libre 90 du membre longitudinal creux 92 entre en contact avec l'opercule 20, l'organe d'ouverture 54 appuie sur l'opercule 20, provoquant la rupture de la ligne 32, avantageusement le long du tronçon circonférentiel 34 pour former un volet 38 et une charnière 40. Cette rupture est notamment facilitée par la forme biseautée de l'extrémité libre 90.When the free end 90 of the hollow longitudinal member 92 comes into contact with the cap 20, the opening member 54 presses against the cap 20, causing the line 32 to break, advantageously along the circumferential section 34 to forming a flap 38 and a hinge 40. This break is particularly facilitated by the beveled shape of the free end 90.

Puis, l'utilisateur poursuit le déplacement du récipient 12 le long de l'axe d'insertion B-B', jusqu'à ce que l'opercule 20 bute contre l'épaulement de blocage 66. Le récipient 12 occupe alors la position d'ouverture.Then, the user continues moving the container 12 along the insertion axis B-B ', until the cap 20 abuts against the locking shoulder 66. The container 12 then occupies the position opening.

Dans cette position, l'organe d'ouverture 54 a pénétré partiellement dans le volume intérieur 18 du récipient 12, avantageusement en faisant pivoter le volet 38 autour de la charnière 40. Le récipient 12 est alors ouvert.In this position, the opening member 54 has partially penetrated the interior volume 18 of the container 12, preferably by pivoting the flap 38 around the hinge 40. The container 12 is then open.

Les saillies 98 latérales ont contribué à écarter le volet 38 pour libérer un passage à travers l'opercule 20 pour le produit cosmétique contenu dans le volume 18.The lateral protrusions 98 have helped to move the flap 38 to release a passage through the cover 20 for the cosmetic product contained in the volume 18.

L'orifice amont 94 est disposé dans le volume intérieur 18. L'orifice aval 96 s'étend en partie dans la chambre aval 60, en aval de l'opercule 20. Ceci permet une distribution améliorée de produit cosmétique hors du volume 18 à travers la lumière axiale 100 du membre longitudinal creux 92.The upstream orifice 94 is disposed in the internal volume 18. The downstream orifice 96 extends partly in the downstream chamber 60, downstream of the lid 20. This allows an improved distribution of cosmetic product out of the volume 18 to through the axial lumen 100 of the hollow longitudinal member 92.

Dans cet exemple, le fond du récipient 12 fait en outre saillie hors de l'applicateur 14 facilitant la préhension du nécessaire 10.In this example, the bottom of the container 12 is further protruding from the applicator 14 facilitating the gripping of the necessary 10.

L'utilisateur bascule alors l'applicateur 14 et le récipient 12 vers le bas pour provoquer l'écoulement par gravité du produit cosmétique contenu dans le volume intérieur 18 hors du récipient 12 vers la chambre aval 60.The user then switches the applicator 14 and the container 12 down to cause the gravity flow of the cosmetic product contained in the interior volume 18 out of the container 12 to the downstream chamber 60.

Ensuite, l'utilisateur appuie sur l'organe de poussée 56 pour réduire le volume intérieur de la chambre aval 60. Il provoque ainsi l'expulsion du produit cosmétique contenu dans la chambre 60 à travers l'ouverture aval 74, puis à travers le canal 80 de l'embout d'application 52.Then, the user presses the pushing member 56 to reduce the internal volume of the downstream chamber 60. It thus causes the expulsion of the cosmetic product contained in the chamber 60 through the downstream opening 74, then through the channel 80 of the application tip 52.

Une fois la dose de produit cosmétique distribuée, l'utilisateur peut alors retirer le récipient 12 hors de l'applicateur 14, et introduire ultérieurement un autre récipient 12 contenant du produit cosmétique dans l'applicateur 14.Once the dose of cosmetic product has been dispensed, the user can then withdraw the container 12 from the applicator 14, and subsequently introduce another container 12 containing cosmetic product into the applicator 14.

L'applicateur 14 selon l'invention est donc particulièrement adapté pour être monté sur le récipient 12 en vue d'ouvrir le récipient 12 et de permettre ensuite la distribution du produit cosmétique qu'il contient.The applicator 14 according to the invention is therefore particularly adapted to be mounted on the container 12 in order to open the container 12 and then allow the dispensing of the cosmetic product it contains.

La gestuelle d'utilisation de l'applicateur 14 est simple et fiable, puisqu'il suffit de déplacer le récipient 12 en translation dans la chambre amont 58, quelle que soit l'orientation angulaire initiale du récipient 12, sans rotation du récipient 12.The gesture of use of the applicator 14 is simple and reliable, since it is sufficient to move the container 12 in translation in the upstream chamber 58, regardless of the initial angular orientation of the container 12, without rotating the container 12.

La présence d'un organe d'ouverture 54 creux, présentant un orifice amont 94 disposé dans le récipient 12 et un orifice aval 96 débouchant au moins en partie hors du récipient 12 garantit une distribution efficace de produit, même si l'ouverture de l'opercule 20 est imparfaite.The presence of a hollow opening member 54 having an upstream orifice 94 disposed in the container 12 and a downstream orifice 96 opening at least partially out of the container 12 ensures efficient product distribution, even if the opening of the operculum 20 is imperfect.

En tout état de cause, l'extrémité libre biseautée 90 de l'organe 54 et les saillies latérales 98 présentes sur cet organe 54, et/ou la forme particulière de la ligne de rupture 32 sur l'opercule 20 contribuent chacun à améliorer la fiabilité de l'ouverture du récipient 12.In any event, the beveled free end 90 of the member 54 and the lateral projections 98 present on this member 54, and / or the particular form of the rupture line 32 on the lid 20, each contribute to improving the reliability of the opening of the container 12.
