Description

La présente invention concerne les dispositifs de conditionnement et d'application comportant :

  • un récipient,
  • un organe d'application comportant une jupe de fixation sur le récipient, et
  • un support servant au maintien de l'organe d'application sur le récipient et s'étendant au contact d'une face radialement intérieure de la jupe de fixation.
The present invention relates to packaging and application devices comprising:
  • a container,
  • an applicator member having a fixing skirt on the container, and
  • a support for holding the applicator member on the container and extending in contact with a radially inner face of the fixing skirt.

Un tel dispositif est décrit notamment dans la demande de brevet européen EP 1 312 280 A1 et dans US 2003/0129016 . La jupe de fixation vient par ses faces radialement extérieure et intérieure au contact respectivement d'une jupe extérieure du support et d'une cheminée d'amenée du produit.Such a device is described in particular in the application for European patent EP 1,312,280 A1 and in US 2003/0129016 . The fixing skirt comes from its radially outer and inner faces in contact respectively with an outer skirt of the support and a product feed chimney.

L'augmentation du diamètre intérieur de la cheminée d'amenée accompagnant l'accroissement de la taille de l'organe d'application peut conduire à une arrivée trop importante de produit lors de l'utilisation. Par ailleurs, si seul le diamètre de la jupe de fixation est augmenté, celle-ci n'est plus maintenue que par la jupe extérieure du support, ce qui peut dans certains cas entraîner un risque de séparation de l'organe d'application et du support à l'utilisation.The increase in the internal diameter of the feed pipe accompanying the increase in the size of the applicator member may lead to an excessive arrival of product during use. Furthermore, if only the diameter of the fixing skirt is increased, it is maintained only by the outer skirt of the support, which may in certain cases involve a risk of separation of the application member and from support to use.

En outre, une cheminée d'amenée de trop faible diamètre est susceptible d'entraîner une mauvaise répartition du produit dans l'organe d'application, notamment lorsque celui-ci est une poudre.In addition, a supply duct of too small diameter is likely to cause a poor distribution of the product in the applicator member, especially when it is a powder.

Il existe un besoin pour bénéficier dans un dispositif du type rappelé ci-dessus à la fois d'une alimentation satisfaisante en produit de l'organe d'application et d'une fixation fiable de l'organe d'application sur le support.There is a need to benefit in a device of the type recalled above both a satisfactory supply of product of the application member and a reliable attachment of the applicator member on the support.

L'invention vise notamment à répondre à ce besoin.The invention aims in particular to meet this need.

L'invention a pour objet, selon l'un de ses aspects, un dispositif de conditionnement et d'application d'un produit, selon la revendication 1.The object of the invention is, according to one of its aspects, a device for packaging and applying a product, according to claim 1.

Grâce à l'invention, l'organe d'application peut être maintenu par serrage par exemple entre deux parois du support tout en permettant d'alimenter de manière adaptée l'organe d'application, en choisissant notamment la section offerte par le support à l'écoulement du produit vers l'organe d'application.Thanks to the invention, the applicator member can be held by clamping, for example, between two walls of the support while allowing the applicator member to be fed in a suitable manner, in particular by choosing the section offered by the support to the flow of the product to the application member.

La face radialement intérieure de la jupe de fixation peut être symétrique de révolution autour de l'axe précité, mais d'autres formes sont possibles, en variante.The radially inner face of the fixing skirt may be symmetrical about the aforementioned axis, but other forms are possible, alternatively.

La section transversale de la cheminée d'amenée peut être polygonale par exemple, notamment triangulaire, carrée ou hexagonale, et peut venir au contact de la jupe de fixation par des arêtes.The cross section of the feed duct may be polygonal for example, in particular triangular, square or hexagonal, and may come into contact with the fixing skirt by edges.

Le support peut comporter ou non une deuxième cheminée à l'intérieur de la première, afin par exemple de créer une perte de charge supplémentaire.The support may or may not include a second chimney inside the first, for example to create an additional pressure drop.

Le support peut comporter des montants ou des cheminées s'étendant au contact de la face radialement intérieure de la jupe de fixation. Les montants peuvent être reliés, dans une réalisation particulière, par des parois s'étendant radialement à une cheminée d'amenée du produit et ces montants peuvent être constitués par exemple par des portions de cylindre, lesquelles peuvent être coaxiales à la cheminée d'amenée.The support may comprise uprights or chimneys extending in contact with the radially inner face of the fixing skirt. The uprights may be connected, in a particular embodiment, by walls extending radially to a product feed chimney and these uprights may be constituted for example by cylinder portions, which may be coaxial with the supply chimney. .

Toujours dans une réalisation particulière, le support peut comporter des ailettes radiales venant en appui par un bord radialement extérieur contre la face radialement intérieure de la jupe de fixation. Ces ailettes peuvent se raccorder à une cheminée d'amenée du produit.Still in a particular embodiment, the support may comprise radial fins bearing by a radially outer edge against the radially inner face of the fixing skirt. These fins can be connected to a product inlet chimney.

Le support peut encore comporter au moins deux cheminées d'amenée du produit, notamment au moins trois cheminées d'amenée du produit, ces cheminées venant en appui par au moins une génératrice contre la face radialement intérieure de la jupe de fixation. Ces cheminées sont non concentriques. Ces cheminées peuvent présenter une section transversale circulaire ou non, par exemple réniforme, continue ou non.The support may also comprise at least two feed chimneys of the product, in particular at least three feed chimneys of the product, these chimneys abutting by at least one generatrix against the radially inner face of the skirt of the product. fixation. These chimneys are non-concentric. These chimneys may have a circular cross section or not, for example reniform, continuous or not.

Dans un exemple de mise en oeuvre de l'invention, le support comporte une jupe extérieure venant au moins en partie au contact d'une face radialement extérieure de la jupe de fixation.In an exemplary implementation of the invention, the support comprises an outer skirt at least partly in contact with a radially outer face of the fixing skirt.

Le support peut être constitué par une pièce rapportée sur le corps du récipient. Le support peut notamment être réalisé de manière à se fixer par encliquetage ou vissage par exemple sur un col du récipient. En variante, le support est réalisé d'une seule pièce, par moulage, avec le corps du récipient.The support may be constituted by an insert on the body of the container. The support may in particular be made to be fixed by snapping or screwing for example on a neck of the container. Alternatively, the support is made in one piece, by molding, with the body of the container.

L'organe d'application peut être en appui au moins partiellement contre un bord libre du support, ou en variante être au moins partiellement espacé d'un bord libre du support, par exemple pour former une chambre d'accumulation du produit. L'organe d'application peut notamment comporter une paroi dont une première face définit une surface d'application et le support peut être agencé pour venir en appui au repos contre une deuxième face de la paroi, opposée à la première. Le support peut ainsi s'opposer à l'enfoncement de l'organe d'application lorsque celui-ci est pressé contre la surface à traiter.The applicator member may be supported at least partially against a free edge of the support, or alternatively may be at least partially spaced from a free edge of the support, for example to form a product accumulation chamber. The applicator member may in particular comprise a wall whose first face defines an application surface and the support may be arranged to bear rest against a second face of the wall, opposite to the first. The support can thus oppose the depression of the applicator member when it is pressed against the surface to be treated.

L'organe d'application peut être symétrique de révolution, de diamètre extérieur compris par exemple entre 12 et 100 mm.The applicator member may be symmetrical with revolution, with an outside diameter of, for example, between 12 and 100 mm.

L'organe d'application peut comporter au moins une gorge annulaire ouverte radialement vers l'extérieur. Cela peut lui conférer davantage de flexibilité.The applicator member may comprise at least one annular groove open radially outwards. This can give it more flexibility.

La jupe de fixation de l'organe d'application peut être fixe par rapport au récipient, étant par exemple maintenue par serrage sur le support. En variante, la jupe de fixation peut être mobile par rapport à une partie du récipient.The fixing skirt of the applicator member may be fixed relative to the container, for example being held by clamping on the support. Alternatively, the fixing skirt may be movable relative to a portion of the container.

L'organe d'application peut présenter une surface d'application généralement convexe vers l'extérieur, ou en variante une surface d'application comportant au moins un bossage ou un creux, ou encore ayant une forme généralement conique, pyramidale ou biseautée. La surface d'application peut encore s'étendre, par exemple, dans une directement sensiblement perpendiculaire à un axe de la jupe de fixation.The applicator member may have a generally convex application surface to the outside, or alternatively an application surface comprising at least one boss or a depression, or alternatively having a generally conical, pyramidal or bevelled shape. The application surface can also extend, for example, in a directly substantially perpendicular to an axis of the fixing skirt.

L'organe d'application est avantageusement compressible, notamment élastiquement compressible, étant par exemple réalisé dans une mousse, laquelle peut être perméable au produit. Par « élastiquement compressible », il faut comprendre que l'organe d'application peut se déformer sensiblement lors de l'application. L'organe d'application peut notamment se déformer dans le sens axial, par exemple lors de l'application manuelle de la surface servant à l'application contre la surface à enduire de produit et/ou lors de la fermeture manuelle du dispositif. L'organe d'application peut être élastiquement compressible dans toute direction. L'organe d'application peut comporter ou non un flocage. L'organe d'application peut contenir, le cas échéant, un agent bactéricide ou antifongique. L'organe d'application peut par exemple être réalisé dans un matériau différent d'un fritté de PE, PP, PTFE, PVDF, EVA, Nylon 6, TPU, copolymères de PE et de PP, par exemple du Porex®.The applicator member is advantageously compressible, in particular elastically compressible, being for example made of a foam, which may be permeable to the product. By "elastically compressible", it must be understood that the organ application can be deformed significantly during application. The applicator member may in particular be deformed in the axial direction, for example during the manual application of the surface used for the application against the surface to be coated with product and / or during the manual closing of the device. The applicator member may be elastically compressible in any direction. The application member may or may not include flocking. The application member may contain, where appropriate, a bactericidal or antifungal agent. The applicator member may for example be made of a material different from a sinter of PE, PP, PTFE, PVDF, EVA, Nylon 6, TPU, copolymers of PE and PP, for example Porex®.

Le dispositif peut comporter un capot de fermeture du récipient. Ce capot peut être agencé pour se fixer de manière étanche sur le récipient. L'organe d'application peut être comprimé ou non quand le capot est en place sur le récipient.The device may comprise a closing cap of the container. This cover can be arranged to attach sealingly to the container. The applicator member may be compressed or not when the cap is in place on the container.

L'axe de la jupe de fixation peut être confondu avec un axe longitudinal du récipient, ou en variante faire un angle α non nul avec l'axe longitudinal du récipient.The axis of the fixing skirt may be coincident with a longitudinal axis of the container, or alternatively make a non-zero angle α with the longitudinal axis of the container.

Le récipient peut comporter une paroi extérieure et le produit peut être au contact de cette paroi. En variante, le produit peut être contenu dans une poche souple. Le récipient peut comporter une paroi extérieure flexible, à l'intérieur de laquelle est placée la poche souple, et le récipient peut être équipé d'un clapet d'admission d'air permettant une entrée d'air dans l'espace situé entre la poche et la paroi extérieure. La poche peut être équipée d'un clapet de sortie permettant une circulation unidirectionnelle du produit vers le support et l'organe d'application.The container may comprise an outer wall and the product may be in contact with this wall. Alternatively, the product may be contained in a flexible pouch. The container may comprise a flexible outer wall, inside which the flexible bag is placed, and the container may be equipped with an air intake valve allowing an air inlet in the space between the pocket and the outer wall. The bag may be equipped with an outlet valve allowing unidirectional circulation of the product towards the support and the application member.

Le dispositif peut comporter un moyen de distribution actionnable par l'utilisateur pour alimenter l'organe d'application en produit. Un tel moyen de distribution peut être choisi par exemple parmi les pompes ou les valves.The device may comprise a dispensing means operable by the user for supplying the applicator member with product. Such a dispensing means may be chosen for example from pumps or valves.

Le dispositif peut comporter un système de fermeture temporaire d'une communication entre l'espace du récipient contenant le produit et l'organe d'application, un tel système de fermeture comportant par exemple un clapet ou un robinet.The device may include a system for temporarily closing a communication between the space of the container containing the product and the applicator member, such a closure system comprising for example a valve or a valve.

L'épaisseur de la jupe de l'organe d'application, mesurée perpendiculairement à l'axe X de celle-ci, peut être supérieure à l'épaisseur de la partie servant à l'application, mesurée selon l'axe X. L'épaisseur de la partie servant à l'application peut être choisie en fonction de la nature du produit, étant par exemple d'autant plus faible que le produit est visqueux.The thickness of the skirt of the applicator member, measured perpendicularly to the axis X thereof, may be greater than the thickness of the portion for the application, measured along the X axis. The thickness of the part used for the application can be chosen according to the nature of the product, being for example the lower the product is viscous.

L'épaisseur de la jupe peut être mesurée en l'absence de compression radiale de celle-ci, par exemple avant son montage sur le dispositif.The thickness of the skirt may be measured in the absence of radial compression thereof, for example before mounting on the device.

L'organe d'application peut ou non reposer contre la première cheminée en l'absence d'utilisation ou lorsque le dispositif n'est pas utilisé. Quand le dispositif est utilisé, l'organe d'application peut venir ou non en appui contre la première cheminée.The applicator member may or may not rest against the first chimney in the absence of use or when the device is not used. When the device is used, the applicator member may or may not bear against the first chimney.

Le récipient peut contenir un produit cosmétique destiné à être appliqué sur le corps, notamment le buste ou les jambes, par exemple un produit de maquillage ou de soin, notamment un produit de protection solaire ou un autobronzant. Le récipient peut également contenir un produit capillaire ou dermatologique.The container may contain a cosmetic product intended to be applied to the body, in particular the bust or the legs, for example a make-up or care product, especially a sun protection product or a self-tanning product. The container may also contain a hair or dermatological product.

  • une paroi s'étendant entre le premier espace et l'organe d'application,
  • au moins une première cheminée se raccordant à ladite paroi,

Le dispositif 1 représenté à la figure 1 comporte un récipient 3 comprenant un corps 4 ayant un col 9 d'axe X sur lequel est fixé un support 5 portant un organe d'application 6. En variante, le support 5 peut être réalisé d'un seul tenant par moulage de matière, notamment thermoplastique, avec au moins une partie du corps 4.The device 1 represented at figure 1 comprises a container 3 comprising a body 4 having a neck 9 of axis X on which is fixed a support 5 carrying an applicator member 6. As a variant, the support 5 can be made in one piece by molding of material, in particular thermoplastic, with at least a part of the body 4.

Ce dernier définit un premier espace 7 qui contient un produit P qui peut être un liquide ou une poudre, notamment un produit cosmétique, y compris de soin.The latter defines a first space 7 which contains a product P which may be a liquid or a powder, in particular a cosmetic product, including a care product.

L'organe d'application 6 est réalisé dans un matériau poreux, notamment un matériau alvéolaire, tel que par exemple une mousse à cellules ouvertes ou semi ouvertes, par exemple une mousse de polyéthylène, de chlorure de polyvinyle, de polyéther, de polyester, d'acrylonitrile butadiène caoutchouc ou de styrène butadiène caoutchouc, cette liste n'étant pas limitative.The applicator member 6 is made of a porous material, especially a cellular material, such as, for example, an open-cell or semi-open-cell foam, for example a polyethylene, polyvinyl chloride, polyether or polyester foam, acrylonitrile butadiene rubber or styrene butadiene rubber, this list is not limiting.

Le dispositif 1 comporte en outre un organe de fermeture 8 qui est par exemple agencé pour se fixer par vissage ou encliquetage sur une jupe extérieure 17 du support 5. Cet organe de fermeture 8 est de préférence agencé de façon à s'appliquer de manière étanche sur le support 5. Il peut comporter à cet effet, par exemple, une lèvre annulaire d'étanchéité 30 s'appliquant sur la face radialement intérieure de la jupe extérieure 17.The device 1 further comprises a closure member 8 which is for example arranged to be fixed by screwing or snapping on an outer skirt 17 of the support 5. This closure member 8 is preferably arranged so as to apply sealingly on the support 5. It may comprise for this purpose, for example, an annular sealing lip 30 applied on the radially inner face of the outer skirt 17.

Dans l'exemple considéré, le support 5 comporte une paroi 10 s'étendant transversalement à l'axe X, pourvue à sa périphérie d'un rebord 12 encliqueté sur un bourrelet annulaire du col 9.In the example considered, the support 5 comprises a wall 10 extending transversely to the axis X, provided at its periphery with a flange 12 snapped onto an annular bead of the neck 9.

Le support 5 comporte également une cheminée 19 d'amenée du produit, d'axe X, se raccordant inférieurement à la paroi transversale 10 et entourée par la jupe extérieure 17, ménageant avec celle-ci une gorge 20 dans laquelle est au moins partiellement reçue une jupe 22 de l'organe d'application 6, servant à la fixation de celui-ci sur le support 5.The support 5 also comprises a product feed chimney 19, of X axis, which is connected below the transverse wall 10 and surrounded by the outer skirt 17, forming with it a groove 20 in which is at least partially received a skirt 22 of the applicator member 6, serving to fix it on the support 5.

L'organe d'application 6 comporte également une paroi supérieure 26 sur laquelle se raccorde la jupe de fixation 22. La face extérieure de cette paroi 26 définit une surface d'application. La face opposée, intérieure, délimite supérieurement une chambre 25 à l'intérieur du support 5.The applicator member 6 also comprises an upper wall 26 on which the fixing skirt 22 is connected. The outer face of this wall 26 defines an application surface. The opposite inner face delimits a chamber 25 inside the support 5.

La cheminée d'amenée 19 définit un canal 23 permettant au produit P contenu dans le corps du récipient 4 de gagner la chambre 25, pour alimenter l'organe d'application 6 en produit.The feed pipe 19 defines a channel 23 allowing the product P contained in the body of the container 4 to reach the chamber 25, to supply the applicator member 6 with product.

Dans l'exemple considéré, l'organe d'application 6 est en communication fluidique avec la réserve de produit sans l'intermédiaire d'aucune valve. En variante, comme on le verra plus loin, l'organe d'application peut être alimenté en produit après traversée par celui-ci d'une valve ou d'un système de fermeture actionnable par l'utilisateur, ce système de fermeture permettant par exemple d'empêcher que du produit n'atteigne l'organe d'application durant le transport du dispositif dans un sac à main, par exemple.In the example considered, the applicator member 6 is in fluid communication with the product reservoir without the intermediary of any valve. Alternatively, as will be seen below, the applicator member may be supplied with product after passing therethrough with a valve or closure system actuated by the user, this closure system allowing for for example to prevent the product from reaching the application member during transport of the device in a purse, for example.

L'organe d'application 6 peut être réalisé avec diverses formes et la jupe de fixation 22 peut notamment comporter, comme c'est le cas dans l'exemple illustré, une gorge annulaire périphérique 33.The applicator member 6 may be made with various shapes and the fixing skirt 22 may in particular comprise, as is the case in the illustrated example, a peripheral annular groove 33.

Dans l'exemple illustré, la jupe extérieure 17 présente une forme générale symétrique de révolution autour de l'axe X, la jupe de fixation 22 présente également une face extérieure 40 de forme générale symétrique de révolution, et vient au contact de la jupe extérieure 17 par toute sa circonférence. La face radialement intérieure 41 de la jupe de fixation 22 vient, conformément à un aspect de l'invention, au contact de la cheminée 19 sur moins d'une révolution complète autour de l'axe X.In the example illustrated, the outer skirt 17 has a generally symmetrical shape of revolution about the X axis, the fixing skirt 22 also has an outer face 40 of symmetrical general shape of revolution, and comes into contact with the outer skirt 17 in all its circumference. The radially inner face 41 of the fastening skirt 22 comes, according to one aspect of the invention, in contact with the chimney 19 on less than one complete revolution about the axis X.

Plus particulièrement, dans l'exemple des figures 1 et 2, la cheminée intérieure 19 présente une section transversale carrée, et elle vient au contact de la face intérieure 41 de la jupe de fixation 22 par quatre arêtes 42.In particular, in the example of Figures 1 and 2 , the inner chimney 19 has a square cross-section, and it comes into contact with the inner face 41 of the fastening skirt 22 by four ridges 42.

La jupe de fixation 22 est maintenue au moins par serrage entre la cheminée d'amenée 19 et la jupe extérieure 17, au niveau des arêtes 42.The fastening skirt 22 is held at least by clamping between the feed pipe 19 and the outer skirt 17, at the edges 42.

Bien entendu, la forme de la cheminée d'amenée 19 peut être modifiée sans que l'on sorte du cadre de la présente invention.Of course, the shape of the feed pipe 19 can be modified without departing from the scope of the present invention.

A titre d'exemple, on a représenté à la figure 3 une variante de réalisation dans laquelle la cheminée 19 présente une section transversale triangulaire, venant au contact de la face intérieure 41 de la jupe de fixation par trois arêtes 42. Dans l'exemple de la figure 4, la cheminée 19 présente une section transversale hexagonale.For example, there is shown in the figure 3 an alternative embodiment in which the chimney 19 has a triangular cross section, coming into contact with the inner face 41 of the fixing skirt by three edges 42. In the example of FIG. figure 4 , the chimney 19 has a hexagonal cross section.

Des espaces 45 s'étendent entre la cheminée 19 et la jupe de fixation 22. Ces espaces 45 peuvent être fermés inférieurement par la paroi transversale 10. En variante, ces espaces 45 peuvent communiquer au travers d'orifices réalisés dans la paroi transversale 10 avec l'espace 7 contenant la réserve de produit P, ce qui permet à la fois une alimentation en produit de ces espaces lorsque le récipient est disposé tête en bas et au produit présent dans ceux-ci de retomber par gravité vers le fond du récipient lorsque celui-ci est replacé tête en haut.Spaces 45 extend between the chimney 19 and the fixing skirt 22. These spaces 45 can be closed inferiorly by the transverse wall 10. In a variant, these spaces 45 can communicate through orifices made in the transverse wall 10 with the space 7 containing the product reserve P, which allows both a product supply of these spaces when the container is placed head down and the product present in them to fall by gravity to the bottom of the container when this one is put back upside down.

On a illustré sur les figures 5 et 6 notamment la possibilité de réaliser le support 5 avec une cheminée d'amenée 50 espacée de la jupe de fixation 22. Cette dernière est maintenue serrée entre la face intérieure 40 de la jupe extérieure 17 et des montants 52 qui s'appliquent sur la surface radialement intérieure 41 de la jupe de fixation 22. Les montants 52 sont reliés à la cheminée 50 par des parois 53 s'étendant radialement. Les montants 52 se raccordent inférieurement à la paroi transversale 10.We have illustrated on Figures 5 and 6 in particular the possibility of making the support 5 with a supply duct 50 spaced from the fixing skirt 22. The latter is held tight between the inner face 40 of the outer skirt 17 and the uprights 52 which are applied to the surface radially. 41 of the mounting skirt 22. The uprights 52 are connected to the chimney 50 by walls 53 extending radially. The uprights 52 are connected below the transverse wall 10.

On a illustré sur la figure 5 la possibilité pour les montants 52 de présenter une hauteur différente de celle de la cheminée 50, et notamment de venir en appui par leur tranche supérieure 55 contre l'organe d'application 6.We illustrated on the figure 5 the possibility for the uprights 52 to have a height different from that of the chimney 50, and in particular to bear on their upper edge 55 against the applicator member 6.

La distance séparant l'extrémité supérieure de la cheminée 50 et la face intérieure de la paroi 26 de l'organe d'application peut être faible, voire nulle, afin de permettre à la cheminée 50 de soutenir l'organe d'application 6 lors de l'application, si la paroi 26 s'enfonce sous l'effet de la pression de contact avec la surface traitée.The distance separating the upper end of the chimney 50 and the inner face of the wall 26 of the applicator member may be small, or even zero, in order to allow the chimney 50 to support the applicator member 6 when of the application, if the wall 26 sinks under the effect of the contact pressure with the treated surface.

On a illustré sur la figure 7 la possibilité de réaliser autrement encore le contact entre le support 5 et la face intérieure 41 de la jupe de fixation 22. Dans l'exemple de la figure 7, la face intérieure 41 vient au contact d'ailettes 65 radiales, qui se raccordent à la cheminée d'amenée 50.We illustrated on the figure 7 the possibility of making still further the contact between the support 5 and the inner face 41 of the fixing skirt 22. In the example of the figure 7 , the inner face 41 comes into contact with radial fins 65, which are connected to the inlet chimney 50.

La variante illustrée à la figure 8 diffère de celle de la figure 6 par l'absence des parois 53 reliant les montants 52 à la cheminée d'amenée 50.The variant illustrated in figure 8 differs from that of figure 6 by the absence of the walls 53 connecting the uprights 52 to the feed pipe 50.

L'exemple représenté aux figures 9 et 10 diffère de celui représenté aux figures 5 et 6 par la présence de fentes 67 sur la cheminée d'amenée 50, ces fentes 67 s'étendant sur une partie de la hauteur de la cheminée 50 à partir de son extrémité libre. Les fentes 67 sont par exemple disposées de manière à déboucher, comme illustré, dans les espaces 66 délimités par deux parois 53 adjacentes, entre la cheminée 50 et la jupe de fixation 22.The example shown in Figures 9 and 10 differs from that shown in Figures 5 and 6 by the presence of slots 67 on the feed pipe 50, these slots 67 extending over a portion of the height of the chimney 50 from its free end. The slots 67 are for example arranged to open, as illustrated, in the spaces 66 delimited by two adjacent walls 53, between the chimney 50 and the fixing skirt 22.

On a également illustré à la figure 9 la possibilité de faire communiquer le canal intérieur 68 de la cheminée 50 avec l'espace 7 contenant le produit P par un orifice 69 de plus petit diamètre que le diamètre intérieur de la cheminée 50. Les fentes 67 peuvent faciliter l'écoulement du produit circulant par la cheminée 50 vers les espaces 66.We also illustrated at figure 9 the possibility of communicating the inner channel 68 of the chimney 50 with the space 7 containing the product P by an orifice 69 of smaller diameter than the internal diameter of the chimney 50. The slots 67 can facilitate the flow of the circulating product by the chimney 50 to the spaces 66.

Ces derniers peuvent ne communiquer avec l'espace 7 contenant le produit que par l'intermédiaire de la cheminée 50, comme c'est le cas dans l'exemple de la figure 9.These can communicate with the space 7 containing the product only through the chimney 50, as is the case in the example of the figure 9 .

En variante, comme illustré aux figures 11 et 12, des orifices 70 peuvent être réalisés dans la paroi transversale 10 de manière à permettre aux espaces 66 de communiquer directement avec l'espace 7 contenant le produit P.Alternatively, as illustrated in Figures 11 and 12 , orifices 70 may be made in the transverse wall 10 so as to allow the spaces 66 to communicate directly with the space 7 containing the product P.

On a représenté à la figure 13 une variante de réalisation qui diffère de celle illustrée à la figure 3 par le fait qu'une deuxième cheminée 73 est réalisée à l'intérieur de la première cheminée 19. Les espaces 74 définis entre ces deux cheminées peuvent être obturés ou non par la paroi transversale 10. Ils peuvent notamment n'être que partiellement obturés par la paroi transversale 10 et communiquer au travers d'orifices 76 avec l'espace 7 contenant le produit.We have shown figure 13 an embodiment variant which differs from that illustrated in FIG. figure 3 in that a second chimney 73 is formed inside the first chimney 19. The spaces 74 defined between these two chimneys can be closed off or not by the transverse wall 10. They can in particular be only partially closed by the transverse wall 10 and communicate through orifices 76 with the space 7 containing the product.

On a représenté à la figure 14 une variante de réalisation dans laquelle le support 5 comporte plusieurs cheminées, notamment trois cheminées adjacentes 80, dont les axes sont disposés, par exemple, comme les sommets d'un triangle, ces cheminées venant en appui chacune par au moins une génératrice contre la face radialement intérieure 41 de la jupe de fixation 22.We have shown figure 14 an alternative embodiment in which the support 5 comprises several chimneys, including three adjacent chimneys 80, the axes of which are arranged, for example, as the vertices of a triangle, these chimneys bearing each bearing by at least one generator against the face radially inner 41 of the fixing skirt 22.

Les cheminées 80 peuvent encore être non jointives, comme illustré à la figure 15.The chimneys 80 may still be non-contiguous, as illustrated in FIG. figure 15 .

La paroi transversale 10 peut n'être traversée par des orifices qu'au droit des cheminées 80, ces orifices ayant par exemple même section intérieure que les cheminées 80, ou en variante comporter au moins un orifice additionnel, par exemple une pluralité d'orifices 70 dans une région centrale, comme illustré à la figure 16.The transverse wall 10 may be traversed by orifices only at the chimneys 80, these orifices having, for example, the same internal section as the chimneys 80, or as a variant comprising at least one additional orifice, for example a plurality of orifices. 70 in a central region, as illustrated in figure 16 .

Dans l'exemple des figures 15 et 16, les cheminées 80 sont réniformes en section transversale, mais d'autres formes sont possibles. Au moins l'une des cheminées peut notamment comporter une fente latérale 81, comme illustré sur la figure 17.In the example of Figures 15 and 16 the chimneys 80 are reniform in cross section, but other shapes are possible. At least one of the chimneys may in particular comprise a lateral slot 81, as illustrated in FIG. figure 17 .

Dans le cas où le support comporte plusieurs cheminées, celles-ci peuvent être contenues dans une enveloppe présentant par exemple une portion conique saillante définie par le bord supérieur des cheminées, comme illustré à la figure 18, ou une portion conique rentrante, comme illustré à la figure 19.In the case where the support comprises several chimneys, these can be contained in an envelope having for example a projecting conical portion defined by the upper edge of the chimneys, as illustrated in FIG. figure 18 , or a re-entrant conical portion, as shown in FIG. figure 19 .

On peut réaliser l'organe d'application 6 avec diverses formes et notamment avec une surface extérieure 40 ayant une forme autre que convexe, par exemple avec une concavité centrée sur l'axe X comme illustré à la figure 20, avec au moins un bossage 85 ou un creux 86 comme illustré à la figure 21, avec une forme sensiblement conique ou pyramidale comme illustré à la figure 22 ou avec une forme biseautée, définissant une face d'application inclinée en oblique relativement à l'axe X, comme illustré sur la figure 24.The applicator member 6 can be made with various shapes and in particular with an outer surface 40 having a shape other than convex, for example with a concavity centered on the X axis as illustrated in FIG. figure 20 with at least one boss 85 or hollow 86 as shown in FIG. figure 21 , with a substantially conical or pyramidal shape as illustrated in FIG. figure 22 or with a beveled shape, defining an application face inclined obliquely relative to the axis X, as illustrated in FIG. figure 24 .

Sur la figure 23, l'organe d'application présente une surface extérieure 40 généralement plane et perpendiculaire à l'axe X, au moins dans une région centrale.On the figure 23 , the applicator member has an outer surface 40 generally flat and perpendicular to the axis X, at least in a central region.

On peut voir également à l'examen des figures 22 et 23 notamment que la cheminée 50 peut présenter une hauteur différente de celle des montants 52 et notamment une hauteur supérieure. Cela peut permettre d'éviter un effet de succion dans le cas où l'organe d'application est compressible et comprimé à l'utilisation contre la cheminée 50 puis relâché.We can also see the examination of Figures 22 and 23 in particular that the chimney 50 may have a height different from that of the uprights 52 and in particular an upper height. This may make it possible to avoid a suction effect in the case where the application member is compressible and compressed to use against the chimney 50 and then released.

On peut voir sur la figure 24 que la cheminée 50 peut être réalisée avec un bord libre 87 qui s'étend selon un plan coupant obliquement l'axe X.We can see on the figure 24 that the chimney 50 can be made with a free edge 87 which extends in a plane intersecting the X axis obliquely.

Le récipient 3 peut être réalisé avec diverses formes et par exemple avec une forme facilitant sa préhension et l'application du produit sur le corps, notamment une forme dans laquelle l'axe X de la jupe de fixation fait un angle non nul α avec l'axe longitudinal Y du récipient, comme illustré à la figure 25.The container 3 can be made with various shapes and for example with a shape facilitating its gripping and the application of the product on the body, in particular a shape in which the axis X of the fastening skirt makes a non-zero angle α with the longitudinal axis Y of the container, as illustrated in FIG. figure 25 .

Le récipient 3 peut être réalisé avec une paroi extérieure 83 non rigide, notamment une paroi flexible à mémoire de forme. Une telle paroi peut permettre de créer une surpression à l'intérieur du récipient 3 au moment de la distribution du produit, facilitant la circulation du produit à travers l'organe d'application 6.The container 3 may be made with a non-rigid outer wall 83, in particular a flexible shape-memory wall. Such a wall can make it possible to create an overpressure inside the container 3 at the moment of dispensing the product, facilitating the circulation of the product through the applicator member 6.

Le produit P peut encore être contenu dans une poche souple 90, comme illustré à la figure 26, cette poche étant située à l'intérieur du récipient 3. L'espace 91 compris entre la poche 90 et la paroi extérieure 83 du récipient 3 peut être équipé d'un clapet d'admission d'air 93, celui-ci s'ouvrant seulement lorsqu'une dépression est créée dans l'espace 91. La poche 90 peut se raccorder à un embout 94 engagé dans le col 9 du récipient, étant maintenu sur celui-ci par exemple par la pièce de support 5. L'embout 94 peut être équipé d'un clapet 96 de sortie de produit ne s'ouvrant que lorsqu'une surpression est créée à l'intérieur de la poche 90. Les clapets 93 et 96 peuvent par exemple être en élastomère et surmoulés.The product P can still be contained in a flexible bag 90, as shown in FIG. figure 26 , this pocket being located inside the container 3. The space 91 between the pocket 90 and the outer wall 83 of the container 3 may be equipped with an air intake valve 93, the latter opening only when a vacuum is created in the space 91. The pocket 90 can be connected to a tip 94 engaged in the neck 9 of the container, being held on it for example by the support piece 5. The tip 94 can be equipped with a valve 96 output product opening only when an overpressure is created inside the pocket 90. The valves 93 and 96 may for example be made of elastomer and overmolded.

Dans cet exemple, la paroi extérieure 83 du récipient 3 est de préférence une paroi souple élastiquement déformable. Lorsque l'utilisateur appuie sur celle-ci, cela réduit le volume de l'espace intérieur 91, ce qui génère une surpression sur la poche 90 et le départ de produit à travers le clapet de sortie 96. Lorsque l'utilisateur relâche la paroi extérieure 83, et qu'une dépression se créée suite à la diminution du volume intérieur de la poche 90, le clapet d'admission 93 peut s'ouvrir pour permettre un rééquilibrage des pressions.In this example, the outer wall 83 of the container 3 is preferably an elastically deformable flexible wall. When the user presses on it, this reduces the volume of the internal space 91, which generates an overpressure on the pocket 90 and the product flow through the outlet valve 96. When the user releases the wall 83, and a depression is created due to the decrease in the internal volume of the pocket 90, the inlet valve 93 can open to allow a rebalancing of the pressures.

Dans l'exemple de la figure 27, l'espace intérieur à la cheminée 19 communique avec la réserve de produit par l'intermédiaire d'orifices 70 réalisés à travers la paroi transversale 10. Cela permet de créer une perte de charge supplémentaire.In the example of the figure 27 , the space inside the chimney 19 communicates with the supply of product through orifices 70 made through the transverse wall 10. This creates an additional pressure drop.

Dans l'exemple de la figure 28, on a illustré la possibilité pour le capot 8 de ne pas venir en contact avec l'organe d'application 6 lorsqu'il est en place sur le récipient 3. L'étanchéité de la fermeture du récipient peut être obtenue par exemple par appui du capot contre la surface radialement extérieure de la jupe extérieure 17.In the example of the figure 28 the possibility has been illustrated for the cover 8 not to come into contact with the applicator member 6 when it is in place on the receptacle 3. The sealing of the closure of the receptacle can be obtained for example by pressing the cover against the radially outer surface of the outer skirt 17.

L'alimentation de l'organe d'application en produit peut s'effectuer en retournant le récipient pour l'amener tête en bas, ou en secouant le récipient.Feeding the applicator member product can be done by inverting the container to bring it upside down, or by shaking the container.

Un moyen de distribution actionnable par l'utilisateur peut encore être utilisé. A titre d'exemple, on a représenté à la figure 29 un moyen de distribution 100 tel qu'une pompe ou une valve. Le support 5 peut être agencé pour coopérer avec une tige 101 de pompe ou de valve, dont le déplacement, par exemple l'enfoncement selon l'axe X, provoque la distribution de produit, par exemple, dans le canal 23 de la cheminée 19 dans l'exemple illustré. Le produit peut, dans le cas de l'utilisation d'une valve, être contenu sous une forme pressurisée dans le récipient.User-operable dispensing means can still be used. For example, there is shown in the figure 29 a dispensing means 100 such as a pump or a valve. The support 5 can be arranged to cooperate with a pump or valve stem 101, the displacement of which, for example the depression along the X axis, causes the product to be dispensed, for example, in the channel 23 of the chimney 19 in the example shown. The product may, in the case of the use of a valve, be contained in a pressurized form in the container.

On peut encore prévoir un système de fermeture temporaire de la communication entre la réserve de produit contenue dans le récipient et l'organe d'application.It is also possible to provide a system for temporarily closing the communication between the supply of product contained in the container and the application member.

A titre d'exemple non limitatif d'un tel système, on a représenté partiellement à la figure 30 un support 5 mobile en rotation relativement à une pièce 105 fixée sur le col du récipient, entre une position fermée et une position ouverte, dans laquelle le produit peut gagner l'organe d'application 6 en traversant au moins un orifice 106 de la pièce 105 et une ouverture 107 ménagée entre des jupes 108 et 109 concentriques et appartenant respectivement au support 5 et à la pièce 105. Lorsque le support 5 est en position de fermeture, les jupes 108 et 109 ferment l'ouverture 107. Le système de fermeture pourrait encore être agencé pour que la commande d'ouverture et de fermeture s'effectue par un déplacement axial du support 5 relativement à la pièce 105.By way of non-limiting example of such a system, there is shown partially in the figure 30 a support 5 movable in rotation relative to a workpiece 105 fixed on the neck of the receptacle, between a closed position and an open position, in which the product can reach the applicator member 6 by passing through at least one orifice 106 of the workpiece 105 and an opening 107 formed between skirts 108 and 109 concentric and respectively belonging to the support 5 and the part 105. When the support 5 is in the closed position, the skirts 108 and 109 close the opening 107. The closure system could also be arranged so that the opening and closing control is effected by an axial displacement of the support 5 relative to the part 105.

Bien entendu, l'invention n'est pas limitée aux exemples qui viennent d'être décrits et l'on peut combiner entre elles les caractéristiques des différents modes de réalisation. On peut notamment équiper le récipient de la figure 25 de l'une des têtes de distribution représentées sur les figures 1 à 16 par exemple et l'organe d'application 6 de ces figures peut lui-même être remplacé par l'un des organes d'application représentés sur les figures 20 à 24.Of course, the invention is not limited to the examples which have just been described and the characteristics of the various embodiments can be combined with one another. In particular, it is possible to equip the container with figure 25 of one of the distribution heads represented on the Figures 1 to 16 for example and the application member 6 of these figures can itself be replaced by one of the application members shown on the Figures 20 to 24 .

L'organe d'application 6 peut être réalisé dans un matériau autre qu'une mousse, par exemple un feutre, une éponge ou un fritté d'une matière plastique ou minérale. L'organe d'application 6 peut présenter une structure monobloc ou multicouche, et comporter par exemple en surface un tissé, un non-tissé ou un flocage. La paroi transversale 10 peut présenter d'autres formes encore, et notamment être réduite à de simples ponts de matière.The applicator member 6 may be made of a material other than a foam, for example a felt, a sponge or a sinter of a plastic or mineral material. The applicator member 6 may have a one-piece or multilayer structure, and for example comprise, on the surface, a woven fabric, a non-woven fabric or a flocking. The transverse wall 10 may have other forms, and in particular be reduced to simple bridges of material.

La ou les cheminées peuvent être continues ou non dans le sens circonférentiel, et présenter le cas échéant des portions de hauteurs et/ou d'étendues circonférentielles inégales.The chimney or chimneys may be continuous or not in the circumferential direction, and may have portions of heights and / or unequal circumferential extents.

Dans toute la description y compris les revendications, l'expression « comportant un » doit être comprise comme étant synonyme de « comportant au moins un » sauf si le contraire est spécifié.Throughout the description including the claims, the phrase "having one" should be understood as being synonymous with "having at least one" unless otherwise specified.
