Definitions

  • the present invention relates to a device for applying a product, in particular viscous liquid, on a lock of hair, and a method of treatment capillary using this device.
  • the invention is particularly suitable for the application of a hair coloring product, strand by strand.
  • the device of the invention can be used for any other hair treatment, such as waving permanent hair, or other specific treatments.
  • the invention is particularly advantageous for the application of a relatively liquid product, under proper conditions.
  • the product to be applied may present itself in the form of a cream, gel or liquid of more or less viscosity high.
  • the dyes for hair is taken from a bowl.
  • Such dyes are intended either for a global use, called “whole head”, in which the hair is totally impregnated with the product, with a view to modifying the color of the whole, ie a more partial use, called “wicks”, where only certain parts of the hair are soaked in product, in order to obtain, once the treatment is finished, an inhomogeneous effect of color, thus emphasizing this or that movement of the hair with lighter or darker shades of color than the natural or overall shade of the hair.
  • Document FR-A-2 589 337 describes a device for applying a dye capillary comprising, on the one hand, a reservoir for the product to be applied and, on the other hand, an application head adapting to the reservoir.
  • the application head has a product supply orifice and carries, at its free end, a two tine fork that the user can guide from one end to the other of a lock of hair, while this is placed between the two teeth of the fork, for the application of the product on said wick.
  • the space between two teeth open directly at their base in an open accumulation cavity of product, into which opens said feed orifice. This cavity is delimited, on its open face, by a movable flap, capable of releasing said cavity in view of easy cleaning of the application head.
  • This device comprises means for isolate a given lock of hair and application means capable of load with hair product.
  • the application of the hair product on the isolated lock is carried out by contacting the application of the wick at a given point of the wick with said application means and by displacement of the means of application relative to said wick from said point, towards a free end of the wick.
  • Retaining means are provided to maintain the wick in application contact with the application means throughout their displacement.
  • Such devices generally suffer from the same drawbacks, linked to the fact, in particular, that they have an open structure. Indeed, due of this structure, the product retained on the means of application tends to flow, especially when the product is relatively liquid. Furthermore, because the hair to be treated does not form a flat surface, the user is obliged to change the orientation of the application device often, depending on the location to be treated. Such an operation further increases the risk of leaking the product to undesirable places. In addition, some such applicators have the disadvantage of having a relatively low autonomy.
  • the invention further aims to provide a device which is of manufacturing cost advantageous.
  • the application device of the invention is particularly suitable for home use, either by the consumer himself, either by a third party with no specific experience in hair dye.
  • a device for the application in wicks of a hair product, in particular a coloring product comprising a member made of at least one elastically deformable and delimiting material at least in part a reserve of said product, said organ also delimiting at at least partly a slit in communication with the reserve of product, and opening onto the outside of the device, said slot being delimited by two edges which, at rest, are substantially contiguous over at least a portion of the slot, so as to form a seal, said slot being capable of being traversed by a wick, so as to allow coating with said product in response movement of the device relative to the drill bit, in a direction longitudinal to said wick.
  • the tightness referred to within the meaning of the present application means a seal or near seal, relative to a composition given. It is clear that the conditions for obtaining such a seal (in particular density of the elastic material, relative support of the edges delimiting the slit) vary depending on the viscosity of the product. Similarly, such a seal corresponds to a seal under normal conditions of use, in particularly with regard to the duration of use of the device.
  • This arrangement allows the support to come into contact with the product, so continuous, over all or part of its length, and this without appreciable flow of produced outside the reserve.
  • the user takes a precise wick, which can be as thin as possible, and position it in the slot.
  • the gesture is simple, precise, and allows rapid coloring of wicks desired hair all or part of its length. Sealing during the application can be ensured regardless of the position of the application device. Accidental product spillage is almost impossible when the elasticity of said elastically deformable member which delimits said slot is suitably chosen. In addition, the risk of putting the product in contact with the user's hands is significantly reduced.
  • the elastically deformable member is designed so that, by crossing the slit, the wick also crosses said reserve of product.
  • one of the two edges delimiting the slot is formed by a portion of an enclosure made in a material impermeable to the product, and inside which is disposed said member made of elastically deformable material, said enclosure comprising a opening extending at least opposite a portion of said slot.
  • the opening of the enclosure is delimited by edges having a profile capable of promoting the insertion of the wick inside the device.
  • the two edges of the slot are formed by said member of elastically deformable material.
  • a first edge of the slot may be formed by a part of said member in a first elastically deformable material.
  • the second edge of the slot is formed by a part of said member, made of a second elastic material deformable.
  • the reserve can be sealed from the outside even with large volume wicks, and this without risk of leakage of the product outside the reserve, whatever the position of the device application.
  • the two parts of said member are mounted so as to exert an appropriate compression between said first and second edges.
  • the slit is produced in a substantially contiguous manner. Also, a relatively large wick can be supported between the means of application.
  • This arrangement has another advantage. Indeed, due to the elastic compression exerted between the first and second edges of the slot, it produces a spin of the wick during treatment. In this way, everything excess product, deposited on the wick in the reserve, is retained before leaving of the wick out of the slot. Thus, a wick already impregnated with product, does not therefore cannot cause, by contacting an untreated part of the hair, the unwanted coloring thereof.
  • the elastically deformable material (s) is (are) chosen from the group of elastomers of copolymers of propylene / ethylene; polyether blockamides; polyvinyls; of the terpolymers of ethylene, propylene and a diene (EPDM); copolymers block styrene-butadiene-styrene (SBS); butylene-styrene / styrene-isoprene-styrene copolymers sequenced (SEBS-SIS); polyurethanes thermoplastics; mixtures of polypropylene with one of the elastomers following: block butylene-styrene / styrene-isoprene-styrene copolymers (SEBS-SIS); terpolymers of ethylene, propylene and a diene (EPDM); styrene-butadiene-styrene block copolymers (S

Description

La présente invention a trait à un dispositif d'application d'un produit, notamment liquide à visqueux, sur une mèche de cheveux, et à un procédé de traitement capillaire à l'aide de ce dispositif. L'invention est tout particulièrement adaptée à l'application d'un produit de coloration capillaire, mèche par mèche. Le dispositif de l'invention peut servir à tout autre traitement capillaire, tel qu'une ondulation permanente des cheveux, ou bien d'autres traitements spécifiques. L'invention est particulièrement avantageuse pour l'application d'un produit relativement liquide, dans des conditions propres. Cependant, le produit à appliquer peut se présenter sous forme d'une crème, d'un gel ou d'un liquide de viscosité plus ou moins élevée.The present invention relates to a device for applying a product, in particular viscous liquid, on a lock of hair, and a method of treatment capillary using this device. The invention is particularly suitable for the application of a hair coloring product, strand by strand. The device of the invention can be used for any other hair treatment, such as waving permanent hair, or other specific treatments. The invention is particularly advantageous for the application of a relatively liquid product, under proper conditions. However, the product to be applied may present itself in the form of a cream, gel or liquid of more or less viscosity high.

Dans le cas d'un produit de coloration capillaire, typiquement, les teintures pour cheveux sont prélevées à partir d'un bol. De telles teintures sont destinées soit à une utilisation globale, dite "tête entière", dans laquelle la chevelure est totalement imprégnée du produit, dans l'optique d'en modifier la couleur de l'ensemble, soit à une utilisation plus partielle, dite "en mèches", où seules certaines parties de la chevelure sont imbibées de produit, afin d'obtenir, une fois le traitement terminé, un effet non homogène de couleur, soulignant ainsi tel ou tel mouvement de la chevelure avec des nuances de couleurs plus claires ou plus sombres que la nuance naturelle ou globale de la chevelure.In the case of a hair coloring product, typically, the dyes for hair is taken from a bowl. Such dyes are intended either for a global use, called "whole head", in which the hair is totally impregnated with the product, with a view to modifying the color of the whole, ie a more partial use, called "wicks", where only certain parts of the hair are soaked in product, in order to obtain, once the treatment is finished, an inhomogeneous effect of color, thus emphasizing this or that movement of the hair with lighter or darker shades of color than the natural or overall shade of the hair.

Le document FR-A-2 589 337 décrit un dispositif pour l'application d'une teinture capillaire comportant, d'une part, un réservoir pour le produit à appliquer et, d'autre part, une tête d'application s'adaptant sur le réservoir. La tête d'application comporte un orifice d'alimentation en produit et porte, à son extrémité libre, une fourche à deux dents que l'utilisateur peut guider d'une extrémité à l'autre d'une mèche de cheveux, alors que celle-ci est placée entre les deux dents de la fourche, en vue de l'application du produit sur ladite mèche. L'espace séparant les deux dents s'ouvre directement à leur base dans une cavité ouverte d'accumulation de produit, dans lequel débouche ledit orifice d'alimentation. Cette cavité est délimitée, sur sa face ouverte, par un volet mobile, apte à dégager ladite cavité en vue d'un nettoyage aisé de la tête d'application.Document FR-A-2 589 337 describes a device for applying a dye capillary comprising, on the one hand, a reservoir for the product to be applied and, on the other hand, an application head adapting to the reservoir. The application head has a product supply orifice and carries, at its free end, a two tine fork that the user can guide from one end to the other of a lock of hair, while this is placed between the two teeth of the fork, for the application of the product on said wick. The space between two teeth open directly at their base in an open accumulation cavity of product, into which opens said feed orifice. This cavity is delimited, on its open face, by a movable flap, capable of releasing said cavity in view of easy cleaning of the application head.

Un autre type de dispositif, pour l'application en mèches d'un produit capillaire, est décrit par le document FR-A-2 764 488. Ce dispositif comprend des moyens pour isoler une mèche donnée d'une chevelure et des moyens d'application aptes à se charger en produit capillaire. L'application du produit capillaire sur la mèche isolée s'effectue par mise en contact d'application de la mèche en un point donné de la mèche avec lesdits moyens d'application et par déplacement des moyens d'application relativement à ladite mèche à partir dudit point, en direction d'une extrémité libre de la mèche. Des moyens de retenue sont prévus pour maintenir la mèche en contact d'application avec les moyens d'application pendant tout leur déplacement.Another type of device, for the application in strands of a hair product, is described by document FR-A-2 764 488. This device comprises means for isolate a given lock of hair and application means capable of load with hair product. The application of the hair product on the isolated lock is carried out by contacting the application of the wick at a given point of the wick with said application means and by displacement of the means of application relative to said wick from said point, towards a free end of the wick. Retaining means are provided to maintain the wick in application contact with the application means throughout their displacement.

D'autres types de dispositifs pour l'application en mèches d'un produit capillaire se présentent sous forme d'un peigne comportant à l'intérieur des canaux d'alimentation, en communication avec un réservoir de produit. Ces canaux d'alimentation débouchent, soit sur les pointes des dents du peigne, soit sur les espaces séparant les dents.Other types of devices for the application of a hair product in locks are present in the form of a comb comprising inside the channels supply, in communication with a product reservoir. These channels lead either to the tips of the comb teeth or to the spaces between the teeth.

De tels dispositifs souffrent d'une manière générale des mêmes inconvénients, liés au fait, notamment, qu'ils présentent une structure ouverte. En effet, en raison de cette structure, le produit retenu sur les moyens d'application a tendance de couler, notamment lorsque le produit est relativement liquide. En outre, du fait que la chevelure à traiter ne forme pas une surface plane, l'utilisateur est obligé de changer souvent, selon l'endroit à traiter, l'orientation du dispositif d'application. Une telle opération augmente encore le risque de faire couler le produit à des endroits non désirables. De plus, certains applicateurs de ce genre présentent l'inconvénient d'avoir une autonomie relativement faible. Such devices generally suffer from the same drawbacks, linked to the fact, in particular, that they have an open structure. Indeed, due of this structure, the product retained on the means of application tends to flow, especially when the product is relatively liquid. Furthermore, because the hair to be treated does not form a flat surface, the user is obliged to change the orientation of the application device often, depending on the location to be treated. Such an operation further increases the risk of leaking the product to undesirable places. In addition, some such applicators have the disadvantage of having a relatively low autonomy.

Un autre type d'applicateur du type à mèches est décrit dans le brevet US-A-4 942 893. Avec ce type d'applicateur, la partie de la chevelure à teindre est introduite dans une capsule étanche, contenant du produit de coloration. La ou les mèches sont maintenues dans la capsule durant tout le temps nécessaire à l'action du produit de coloration. Ce type d'applicateur convient bien pour l'application de produits nécessitant un certain temps de pose, mais n'est pas du tout adapté à la coloration en mèches évoquée ci-avant.Another type of wick type applicator is described in US-A-4 942 893. With this type of applicator, the part of the hair to be dyed is introduced into a sealed capsule, containing coloring product. The wicks are kept in the capsule for the time necessary to the action of the coloring product. This type of applicator is well suited for the application of products requiring a certain amount of time, but is not all suitable for coloring in highlights mentioned above.

Aussi, est-ce un des objets de l'invention que de fournir un dispositif pour l'application en mèches d'un produit capillaire, ne présentant pas les inconvénients discutés ci-avant, en référence aux dispositifs de la technique antérieure.It is therefore one of the objects of the invention to provide a device for applying a hair product in locks, not having the disadvantages discussed above, with reference to the devices of the technique earlier.

C'est en particulier un objet de l'invention que de fournir un dispositif permettant l'application d'un produit capillaire, dans des bonnes conditions de propreté de manière non-salissante, et ceci quelle que soit la viscosité du produit à appliquer. L'invention vise, en outre, à fournir un dispositif qui soit d'un coût de fabrication avantageux.It is in particular an object of the invention to provide a device allowing the application of a hair product, in good conditions of cleanliness of non-soiling, regardless of the viscosity of the product to be applied. The invention further aims to provide a device which is of manufacturing cost advantageous.

C'est un autre objet de l'invention que de fournir un dispositif permettant l'application d'un produit capillaire, qui soit simple d'utilisation, et qui permette l'application du produit sur toute la longueur de la mèche, depuis la racine jusqu'à son extrémité libre, ou inversement. Le dispositif d'application de l'invention est particulièrement adapté à l'utilisation à domicile, soit par le consommateur lui-même, soit par une tierce personne n'ayant pas d'expérience spécifique en teinture capillaire.It is another object of the invention to provide a device allowing the application of a hair product, which is easy to use, and which allows applying the product over the entire length of the wick, from the root to its free end, or vice versa. The application device of the invention is particularly suitable for home use, either by the consumer himself, either by a third party with no specific experience in hair dye.

D'autres objets de l'invention apparaítront de manière détaillée dans la description qui suit.Other objects of the invention will appear in detail in the description following.

Ces objets sont atteints en réalisant un dispositif pour l'application en mèches d'un produit capillaire, notamment d'un produit de coloration, ledit dispositif comprenant un organe réalisé en au moins un matériau élastiquement déformable et délimitant au moins en partie une réserve dudit produit, ledit organe délimitant également au moins en partie une fente en communication avec la réserve de produit, et débouchant sur l'extérieur du dispositif, ladite fente étant délimitée par deux bords qui, au repos, sont sensiblement jointifs sur au moins une portion de la fente, de manière à former étanchéité, ladite fente étant apte à être traversée par une mèche, de manière à en permettre l'enduction au moyen dudit produit en réponse à un déplacement du dispositif par rapport à la mèche, selon une direction longitudinale à ladite mèche.These objects are achieved by making a device for the application in wicks of a hair product, in particular a coloring product, said device comprising a member made of at least one elastically deformable and delimiting material at least in part a reserve of said product, said organ also delimiting at at least partly a slit in communication with the reserve of product, and opening onto the outside of the device, said slot being delimited by two edges which, at rest, are substantially contiguous over at least a portion of the slot, so as to form a seal, said slot being capable of being traversed by a wick, so as to allow coating with said product in response movement of the device relative to the drill bit, in a direction longitudinal to said wick.

Il est bien entendu que l'étanchéité visée au sens de la présente demande s'entend d'une étanchéité ou quasi-étanchéité, relativement à une composition donnée. Il est clair que les conditions pour obtenir une telle étanchéité (en particulier densité du matériau élastique, appui relatif des bords délimitant la fente) varient en fonction de la viscosité du produit. De même, une telle étanchéité correspond à une étanchéité dans des conditions normales d'utilisation, en particulier en ce qui concerne la durée d'utilisation du dispositif.It is understood that the tightness referred to within the meaning of the present application means a seal or near seal, relative to a composition given. It is clear that the conditions for obtaining such a seal (in particular density of the elastic material, relative support of the edges delimiting the slit) vary depending on the viscosity of the product. Similarly, such a seal corresponds to a seal under normal conditions of use, in particularly with regard to the duration of use of the device.

Cette disposition permet la mise en contact du support avec le produit, de façon continue, sur tout ou partie de sa longueur, et ceci sans écoulement sensible de produit hors de la réserve. A cet effet, l'utilisateur prélève une mèche précise, qui peut être aussi fine que possible, et la positionne dans la fente. Le geste est simple, précis, et permet de réaliser de manière rapide la coloration en mèches souhaitée d'une chevelure sur tout ou partie de sa longueur. L'étanchéité lors de l'application peut être assurée quelle que soit la position du dispositif d'application. Tout écoulement accidentel de produit est quasiment impossible lorsque l'élasticité dudit l'organe élastiquement déformable qui délimite ladite fente, est convenablement choisie. De plus, le risque de mettre le produit en contact avec les mains de l'utilisateur est nettement réduit.This arrangement allows the support to come into contact with the product, so continuous, over all or part of its length, and this without appreciable flow of produced outside the reserve. For this purpose, the user takes a precise wick, which can be as thin as possible, and position it in the slot. The gesture is simple, precise, and allows rapid coloring of wicks desired hair all or part of its length. Sealing during the application can be ensured regardless of the position of the application device. Accidental product spillage is almost impossible when the elasticity of said elastically deformable member which delimits said slot is suitably chosen. In addition, the risk of putting the product in contact with the user's hands is significantly reduced.

En outre, tout en autorisant un mouvement relatif de l'organe délimitant la fente le long de la mèche, celui-ci empêche sensiblement tout mouvement qui conduirait à rompre son contact avec tout ou partie de la mèche en cours de traitement. La mèche est ainsi maintenue dans la fente. Avec une telle configuration, la mèche est "pincée" entre deux parties du dispositif, sans être trop serrée, de manière à autoriser le glissement du dispositif le long de la mèche, depuis l'une de ses extrémités à l'autre. Ainsi, pendant tout le déplacement du dispositif, une portion de la mèche est imprégnée de produit.In addition, while allowing relative movement of the organ delimiting the slot, along the wick, it substantially prevents any movement which would lead to break contact with all or part of the wick during treatment. The wick is thus held in the slot. With such a configuration, the wick is "pinched" between two parts of the device, without being too tight, so as to allow the device to slide along the wick, from one of its ends to each other. Thus, during the entire movement of the device, a portion of the wick is impregnated with product.

De manière avantageuse, l'organe élastiquement déformable est conçu de sorte que, en traversant la fente, la mèche traverse également ladite réserve de produit.Advantageously, the elastically deformable member is designed so that, by crossing the slit, the wick also crosses said reserve of product.

Selon un mode de réalisation particulièrement simple à réaliser, l'un des deux bords délimitant la fente est formé d'une portion d'une enceinte réalisée en un matériau imperméable au produit, et à l'intérieur de laquelle est disposé ledit organe en matériau élastiquement déformable, ladite enceinte comportant une ouverture s'étendant au moins en regard d'une portion de ladite fente. De préférence, l'ouverture de l'enceinte est délimitée par des bords présentant un profil apte à favoriser l'insertion de la mèche à l'intérieur du dispositif.According to a particularly simple embodiment, one of the two edges delimiting the slot is formed by a portion of an enclosure made in a material impermeable to the product, and inside which is disposed said member made of elastically deformable material, said enclosure comprising a opening extending at least opposite a portion of said slot. Of preferably, the opening of the enclosure is delimited by edges having a profile capable of promoting the insertion of the wick inside the device.

Selon un autre mode de réalisation particulièrement préféré, les deux bords de la fente sont formés par ledit organe en matériau élastiquement déformable. Dans ce cas, un premier bord de la fente peut être formé par une partie dudit organe en un premier matériau élastiquement déformable. Le second bord de la fente est formé par une partie dudit organe, constituée d'un second matériau élastiquement déformable. L'étanchéité de la réserve par rapport à l'extérieur peut être assurée même avec des mèches de volume important, et ceci sans risque d'écoulement du produit à l'extérieur de la réserve, quelle que soit la position du dispositif d'application. A cet effet, avantageusement, les deux parties dudit organe sont montées de manière à exercer une compression appropriée entre lesdits premier et second bords. Ainsi, la fente est réalisée de manière sensiblement jointive. Aussi, une mèche de largeur relativement importante peut être prise en charge entre les moyens d'application. According to another particularly preferred embodiment, the two edges of the slot are formed by said member of elastically deformable material. In in this case, a first edge of the slot may be formed by a part of said member in a first elastically deformable material. The second edge of the slot is formed by a part of said member, made of a second elastic material deformable. The reserve can be sealed from the outside even with large volume wicks, and this without risk of leakage of the product outside the reserve, whatever the position of the device application. To this end, advantageously, the two parts of said member are mounted so as to exert an appropriate compression between said first and second edges. Thus, the slit is produced in a substantially contiguous manner. Also, a relatively large wick can be supported between the means of application.

Cette disposition présente un autre avantage. En effet, en raison de la compression élastique exercée entre les premier et second bords de la fente, il se produit un essorage de la mèche en cours de traitement. De cette manière, tout excès de produit, déposé sur la mèche dans la réserve, est retenu avant la sortie de la mèche hors de la fente. Ainsi, une mèche déjà imprégnée de produit, ne peut donc pas provoquer, par mise en contact avec une partie non-traitée de la chevelure, la coloration indésirée de celle-ci.This arrangement has another advantage. Indeed, due to the elastic compression exerted between the first and second edges of the slot, it produces a spin of the wick during treatment. In this way, everything excess product, deposited on the wick in the reserve, is retained before leaving of the wick out of the slot. Thus, a wick already impregnated with product, does not therefore cannot cause, by contacting an untreated part of the hair, the unwanted coloring thereof.

Avantageusement, le (ou les) matériau(x) élastiquement déformable(s) est (sont) choisi(s) dans le groupe des élastomères des copolymères de propylène/éthylène; des polyéther blocamides ; des polyvinyles ; des terpolymères d'éthylène, de propylène et d'un diène (EPDM); des copolymères de styrène-butadiène-styrène séquencés (SBS) ; des copolymères de butylène-styrène/styrène-isoprène-styrène séquencés (SEBS-SIS) ; des polyuréthanes thermoplastiques; des mélanges de polypropylène avec l'un des élastomères suivants : copolymères de butylène-styrène/styrène-isoprène-styrène séquencés (SEBS-SIS) ; terpolymères d'éthylène, de propylène et d'un diène (EPDM) ; copolymères de styrène-butadiène-styrène séquencés (SBS).Advantageously, the elastically deformable material (s) is (are) chosen from the group of elastomers of copolymers of propylene / ethylene; polyether blockamides; polyvinyls; of the terpolymers of ethylene, propylene and a diene (EPDM); copolymers block styrene-butadiene-styrene (SBS); butylene-styrene / styrene-isoprene-styrene copolymers sequenced (SEBS-SIS); polyurethanes thermoplastics; mixtures of polypropylene with one of the elastomers following: block butylene-styrene / styrene-isoprene-styrene copolymers (SEBS-SIS); terpolymers of ethylene, propylene and a diene (EPDM); styrene-butadiene-styrene block copolymers (SBS).

De préférence, la fente s'étend sur une ouverture angulaire comprise entre 20° et 320°, et de préférence comprise entre 120° et 200°. La fente peut être réalisée dans l'organe élastiquement déformable, de manière partielle, par exemple, par découpe mécanique (par un couteau) ou thermique (par laser). Avantageusement, la fente est réalisée sur une profondeur d'environ 1 mm à environ 20 mm, et de préférence d'environ 3 mm à environ 8 mm.Preferably, the slot extends over an angular opening of between 20 ° and 320 °, and preferably between 120 ° and 200 °. Slitting can be done in the elastically deformable member, partially, for example, by mechanical (by knife) or thermal (by laser) cutting. advantageously, the slot is made to a depth of approximately 1 mm to approximately 20 mm, and preferably from about 3 mm to about 8 mm.

Avantageusement, les deux bords de la fente débouchent sur l'extérieur de l'organe en matériau élastiquement déformable, en s'évasant l'un par rapport à l'autre. Ainsi, l'insertion de la mèche dans la fente est facilitée.Advantageously, the two edges of the slot open onto the outside of the member of elastically deformable material, flaring one relative to the other. Thus, the insertion of the wick into the slot is facilitated.

Selon un mode de réalisation, la réserve de produit est délimitée au moins en partie par une portion évidée dudit organe en matériau élastiquement déformable. According to one embodiment, the reserve of product is delimited at least in part by a hollow portion of said member made of elastically deformable material.

Ainsi, l'organe en matériau élastiquement déformable peut former, par exemple, un cylindre dont le centre est évidé de manière à former ladite réserve de produit.Thus, the member made of elastically deformable material can form, for example, a cylinder whose center is hollowed out so as to form said reserve of product.

Selon un autre mode de réalisation, la réserve de produit est formée à l'intérieur de la structure même du matériau formant l'organe élastiquement déformable, notamment par des cellules ouvertes ou semi-ouvertes, communiquant entre elles de manière multi-directionnelle. Dans ce cas, il est possible, de réaliser ledit organe en matériau élastiquement déformable sous forme d'un cylindre plein.According to another embodiment, the product reserve is formed inside the very structure of the material forming the elastically deformable member, in particular by open or semi-open cells, communicating with each other in a multi-directional way. In this case, it is possible to carry out said member made of elastically deformable material in the form of a solid cylinder.

De façon préférentielle, l'organe élastiquement déformable peut être constitué d'une éponge, ou d'une mousse dont la taille des cellules ouvertes ou semi-ouvertes peut être comprise entre environ 0,1 mm et environ 2,5 mm.Preferably, the elastically deformable member can be constituted a sponge, or a foam with open or semi-open cell sizes can be between about 0.1 mm and about 2.5 mm.

De préférence, la mousse ou l'éponge est hydrophile, comme les éponges ou mousses de polyuréthane, de viscose ou de polyester. Ainsi, on peut assurer un glissement doux de la mèche de cheveux entre lesdits bords de la fente. Dans certains cas, en fonction de la nature du produit à appliquer et du support, il peut s'avérer avantageux d'utiliser une mousse ou une éponge hydrophobe, comme les éponges de polyéthylène, de polypropylène ou de polyéther.Preferably, the foam or sponge is hydrophilic, like sponges or polyurethane, viscose or polyester foams. So we can ensure a soft sliding of the lock of hair between said edges of the slit. In in certain cases, depending on the nature of the product to be applied and the support, it may it may be beneficial to use a hydrophobic foam or sponge, such as polyethylene, polypropylene or polyether sponges.

Avantageusement, le dispositif d'application comprend un orifice pouvant être obturé, notamment de façon réversible, de manière à permettre le remplissage de la réserve dudit produit. En particulier, cet orifice est réalisé dans ladite enceinte.Advantageously, the application device comprises an orifice which can be closed, in particular reversibly, so as to allow filling of the reserve of said product. In particular, this orifice is produced in said enclosure.

L'enceinte peut être réalisée, notamment, par moulage d'un matériau thermoplastique plus ou moins rigide, choisi parmi les polyéthylènes, les polypropylènes, les polystyrènes, les chlorures de polyvinyle, les polyéthylènes téréphtalates, etc.. D'autres matériaux encore peuvent être utilisés. Une telle enceinte peut être moulée en deux ou trois pièces, avantageusement sans contre dépouille. Avantageusement, elle est réalisée en un matériau transparent, ce qui permet de vérifier le taux de remplissage du réservoir de produit. The enclosure can be produced, in particular, by molding a material more or less rigid thermoplastic, chosen from polyethylenes, polypropylenes, polystyrenes, polyvinyl chlorides, polyethylenes terephthalates, etc. Still other materials can be used. Such a enclosure can be molded in two or three pieces, advantageously without against bare. Advantageously, it is made of a transparent material, which allows you to check the filling rate of the product tank.

De manière avantageuse, le dispositif d'application de l'invention peut comprendre, en outre, des moyens de préhension, tels qu'un manche allongé.Advantageously, the application device of the invention can further comprise gripping means, such as an elongated handle.

Des moyens peuvent être prévus pour immobiliser l'organe en matériau élastiquement déformable à l'intérieur de ladite enceinte. Avantageusement, l'organe en matériau élastiquement déformable est immobilisé à l'intérieur de ladite enceinte par pincement au moyen d'un (ou de deux) couvercle(s) rapporté(s), obturant ladite enceinte. Un tel pincement peut être réalisé, par exemple, par un ou plusieurs crans ou arêtes, disposés sur le(s) couvercle(s) ou une portion de l'enceinte, en contact avec le(s) couvercle(s). Le(s) couvercle(s) peu(ven)t être monté(s) de manière fixe ou amovible.Means can be provided to immobilize the material organ elastically deformable inside said enclosure. advantageously, the member made of elastically deformable material is immobilized inside said enclosure by pinching by means of one (or two) cover (s) reported (s), closing said enclosure. Such pinching can be achieved, by example, by one or more notches or edges, arranged on the cover (s) or a portion of the enclosure, in contact with the cover (s). The cover (s) can be fixed or removable.

Le dispositif d'application de l'invention peut comprendre, en outre, des moyens pour permettre le montage du dispositif sur un récipient. Ce moyen de montage est apte à former un réservoir auxiliaire, contenant notamment une réserve de produit relativement importante. Dans ce cas, ledit récipient peut être mis, de façon permanente ou sélective, en communication avec ladite réserve de produit. Ledit récipient peut être à parois déformables, permettant par compression, le transvasement d'une dose de produit vers ladite réserve de produit. Le récipient auxiliaire, lorsqu'il est solidarisé avec l'enceinte, peut servir de moyen de préhension.The application device of the invention may further comprise means to allow mounting of the device on a container. This mounting method is suitable for forming an auxiliary tank, containing in particular a reserve of relatively large product. In this case, said container can be put, permanently or selectively, in communication with said reserve of product. Said container may have deformable walls, allowing by compression, the transfer of a dose of product to said reserve of product. The recipient auxiliary, when it is integral with the enclosure, can serve as a means of gripping.

Un autre objet de l'invention est relatif à un procédé pour l'application en mèches d'un produit capillaire, notamment d'un produit de coloration, ledit procédé consistant à :

  • a) isoler une mèche à enduire avec ledit produit ;
  • b) faire traverser par ladite mèche ainsi isolée, une fente délimitée au moins en partie par un organe réalisé en au moins un matériau élastiquement déformable, et délimitant au moins en partie, une réserve dudit produit avec laquelle ladite fente est en communication, ladite fente débouchant sur l'extérieur du dispositif, et étant délimitée par deux bords qui, au repos, sont sensiblement jointifs sur au moins une portion de la fente, de manière à former étanchéité ; et
  • c) déplacer l'organe élastiquement déformable par rapport à ladite mèche, selon une direction longitudinale à ladite mèche.
    • Another subject of the invention relates to a process for the application in locks of a hair product, in particular a coloring product, said process consisting in:
  • a) isolating a wick to be coated with said product;
  • b) passing through said wick thus isolated, a slit delimited at least in part by a member made of at least one elastically deformable material, and delimiting at least in part, a reserve of said product with which said slit is in communication, said slit opening onto the outside of the device, and being delimited by two edges which, at rest, are substantially contiguous over at least one portion of the slot, so as to form a seal; and
  • c) moving the elastically deformable member relative to said wick, in a longitudinal direction to said wick.

    • L'invention consiste, mis à part les dispositions exposées ci-dessus, en un certain nombre d'autres dispositions qui seront explicitées ci-après, à propos d'exemples de réalisation non limitatifs, décrits en référence aux figures annexées, parmi lesquelles :

    • la figure 1 représente une vue en perspective d'un premier mode de réalisation du dispositif d'application selon l'invention, illustré en cours d'utilisation ;

    • les figures 10 et 11 illustrent une vue en coupe axiale d'autres modes de réalisation encore de l'invention.
    The invention consists, apart from the arrangements set out above, of a certain number of other arrangements which will be explained below, with reference to nonlimiting exemplary embodiments, described with reference to the appended figures, among which:
    • FIG. 1 represents a perspective view of a first embodiment of the application device according to the invention, illustrated during use;
    • Figure 2 shows a schematic cross-sectional view of the device shown in Figure 1;

    Les figures 1 à 5 auxquelles il est maintenant fait référence, illustrent différentes vues d'un premier mode de réalisation du dispositif d'application 1 conforme à l'invention.Figures 1 to 5 which are now referred to, illustrate different views of a first embodiment of the application device 1 in accordance with the invention.

    Sur les figures 1 et 2, on voit une mèche isolée de cheveux M, passant entre deux bords 4, 4' d'une fente Q dont est pourvu le dispositif d'application 1. Les deux bords 4, 4' sont formés chacun d'une portion transversale d'un cylindre en mousse alvéolaire à cellules ouvertes ou semi-ouvertes. Le cylindre est de révolution autour d'un axe X. Le cylindre est évidé en son centre et est constitué d'un empilement de deux blocs de mousse 4a, 4b, selon l'axe X. Selon l'exemple de réalisation considéré, chacun des deux blocs de mousse 4a, 4b est réalisé en mousse élastiquement déformable, de même nature.In FIGS. 1 and 2, we see an isolated lock of hair M, passing between two edges 4, 4 'of a slot Q which is provided with the application device 1. The two edges 4, 4 'are each formed of a transverse portion of a cylinder in open or semi-open cell foam. The cylinder is revolution around an X axis. The cylinder is hollowed out at its center and is made up a stack of two blocks of foam 4a, 4b, along the axis X. According to the example embodiment considered, each of the two foam blocks 4a, 4b is made in elastically deformable foam, of the same kind.

    On voit que les deux blocs 4a, 4b formant le cylindre en mousse sont séparées à leur interface par une fente Q, perpendiculaire à l'axe X, et présentant un angle d'ouverture α légèrement supérieur à 180°. La fente Q est sensiblement jointive, et est délimitée par deux extrémités Q1 et Q2, de sorte que la corde C reliant les extrémités de la fente passe sensiblement au centre du réservoir 2. Le cylindre de mousse 4a, 4b est constitué, par exemple d'une mousse hydrophile, telle qu'une mousse de polyuréthane présentant des cellules d'une taille moyenne d'environ 1,5 mm. La partie centrale évidée du cylindre forme une réserve 2 de produit P, de consistance liquide, notamment une composition de teinture pour cheveux.We see that the two blocks 4a, 4b forming the foam cylinder are separated at their interface by a slot Q, perpendicular to the axis X, and having an opening angle α slightly greater than 180 °. The slot Q is substantially contiguous, and is delimited by two ends Q 1 and Q 2 , so that the cord C connecting the ends of the slot passes substantially in the center of the tank 2. The foam cylinder 4a, 4b is constituted, by example of a hydrophilic foam, such as a polyurethane foam having cells with an average size of approximately 1.5 mm. The hollowed-out central part of the cylinder forms a reserve 2 of product P, of liquid consistency, in particular a hair dye composition.

    Le cylindre en mousse 4a, 4b est disposé dans une enceinte rigide ou boítier 20, de forme générale cylindrique, composé d'une partie 20a formant un réceptacle à fond fermé, et d'un couvercle 20b. Le couvercle est fixé, par exemple par encliquetage, sur l'extrémité ouverte du réceptacle 20a.The foam cylinder 4a, 4b is placed in a rigid enclosure or case 20, of generally cylindrical shape, composed of a part 20a forming a receptacle for closed bottom, and a cover 20b. The cover is fixed, for example by snap-fastening, on the open end of the receptacle 20a.

    Le boítier 20 comporte une ouverture 22 de forme allongée, de manière à dégager la fente Q de l'extrémité Q1 jusqu'à l'extrémité Q2. Ainsi, l'ouverture 22 est orientée selon un plan perpendiculaire à l'axe X. L'ouverture 22 est bordée d'une lèvre de guidage 24, légèrement évasée, destinée à favoriser l'introduction de la mèche M dans la fente Q, et à éviter d'abímer les cheveux lors du déplacement du dispositif d'application.The housing 20 has an opening 22 of elongated shape, so as to release the slot Q from the end Q 1 to the end Q 2 . Thus, the opening 22 is oriented along a plane perpendicular to the axis X. The opening 22 is bordered by a guide lip 24, slightly flared, intended to promote the introduction of the wick M into the slot Q, and to avoid damaging the hair when moving the application device.

    Le boítier 20 est pourvu d'un orifice de remplissage 26, obturable à l'aide d'un bouchon 28 amovible. Le bouchon 28 est relié au corps du boítier 20 à l'aide d'une lanière flexible 29, pour éviter la perte dudit bouchon.The housing 20 is provided with a filling orifice 26, which can be closed using a removable plug 28. The plug 28 is connected to the body of the housing 20 using a flexible strap 29, to prevent the loss of said plug.

    L'orifice de remplissage 26 sert à la mise en engagement du boítier 20 avec l'embout de distribution d'un réservoir auxiliaire externe ayant une contenance importante en produit, et permet d'introduire une dose appropriée de produit dans la réserve 2. La mise en engagement de l'orifice 26 avec le réservoir externe peut être effectuée de manière permanente ou temporaire.The filling orifice 26 serves to engage the housing 20 with the dispensing nozzle of an external auxiliary tank having a capacity important in product, and allows to introduce an appropriate dose of product into reserve 2. The engagement of orifice 26 with the external reservoir can be performed permanently or temporarily.

    Pour se servir du dispositif qui vient d'être décrit, une mèche M à traiter est séparée de la chevelure. L'utilisateur saisit alors d'une main le dispositif 1 préalablement chargé en produit P.To use the device which has just been described, a wick M to be treated is separated from the hair. The user then grasps the device 1 with one hand previously loaded with product P.

    Ensuite en passant par l'ouverture 22 du boítier, une portion de la mèche M est introduite dans la fente Q, où elle est prise en sandwich par les bords 4, 4' en mousse définissant la fente. Ainsi, la portion de mèche se situe dans une zone s'étendant sensiblement entre les deux extrémités Q1 et Q2 de la fente, à proximité de la corde C. De cette manière, la portion de la mèche M, emprisonnée élastiquement entre les bords 4, 4', traverse la réserve 2, de manière à venir en contact avec le produit P. En déplaçant le dispositif d'application 1 depuis la racine R de la mèche jusqu'à sa pointe libre E, suivant la flèche F, l'utilisateur peut imprégner en produit P tout ou partie de la mèche, et ce en profondeur. Cette opération peut être exécutée dans le sens inverse, également. Ce processus est répété, mèche par mèche, autant de fois que l'on le souhaite. Toute cette opération s'effectue dans des conditions propres.Then passing through the opening 22 of the housing, a portion of the wick M is introduced into the slot Q, where it is sandwiched by the edges 4, 4 'of foam defining the slot. Thus, the wick portion is located in a zone extending substantially between the two ends Q 1 and Q 2 of the slit, near the cord C. In this way, the portion of the wick M, trapped elastically between the edges 4, 4 ′, crosses the reserve 2, so as to come into contact with the product P. By moving the application device 1 from the root R of the wick to its free point E, along the arrow F, the user can impregnate in product P all or part of the wick, and this in depth. This can also be done in reverse. This process is repeated, wick by wick, as many times as desired. All this operation is carried out under proper conditions.

    Ainsi, avec le dispositif d'application suivant l'invention, il est clair que la mèche traitée (M) est complètement maítrisée et maintenue pendant tout son traitement. En fin de geste, c'est à dire lorsque l'applicateur arrive à la pointe de la mèche, celle-ci est reposée soigneusement sur le reste de la chevelure. Dans le cas d'un produit de coloration, sa viscosité est, avantageusement, telle que le produit ne peut pas migrer de manière significative vers les autres cheveux non traités, de manière à ne pas nuire à l'esthétique de l'application ainsi réalisée.Thus, with the application device according to the invention, it is clear that the wick treated (M) is completely under control and maintained throughout its treatment. At the end of the gesture, i.e. when the applicator reaches the tip of the wick, this is carefully rested on the rest of the hair. In the case of a coloring product, its viscosity is advantageously such that the product does not cannot migrate significantly to other untreated hair, from so as not to harm the aesthetics of the application thus produced.

    On notera que le produit peut être de viscosité faible sans risquer des fuites en dehors de la réserve, quelle que soit la position dans laquelle le dispositif est maintenu par l'utilisateur en cours du traitement. En effet, la pression entre les bords 4, 4' est choisie de sorte que la mèche puisse sortir de la fente correctement essorée.It should be noted that the product can be of low viscosity without risking leakage in outside the reserve, regardless of the position in which the device is maintained by the user during processing. Indeed, the pressure between the edges 4, 4 'is chosen so that the wick can come out of the slot properly wrung out.

    Avantageusement l'ouverture 22, le boítier et le couvercle sont réalisés par moulage, notamment d'un matériau thermoplastique, plus ou moins rigide, tel que du polyéthylène ou du polypropylène. Ce matériau peut être transparent, permettant ainsi de vérifier le niveau de remplissage en produit dans la réserve 2.Advantageously the opening 22, the housing and the cover are made by molding, in particular of a more or less rigid thermoplastic material, such as polyethylene or polypropylene. This material can be transparent, thus making it possible to check the level of filling with product in reserve 2.

    Sur les figures 3 à 5, pour des raisons de simplification, l'orifice de remplissage du dispositif 1 n'a pas été représenté. Ces figures montrent, plus en détail, différents aspects du mode de réalisation décrit précédemment.In FIGS. 3 to 5, for reasons of simplification, the filling orifice of the device 1 has not been shown. These figures show, in more detail, different aspects of the embodiment described above.

    Sur la figure 3 on voit que le cylindre en mousse 4a, 4b est maintenu dans le boítier 20 par des jupes 25a et 25b, concentriques avec la paroi cylindrique extérieure du boítier 20. Ces jupes 25a et 25b sont portées par le réceptacle 20a et le couvercle 20b respectivement. Les jupes sont de hauteur telle qu'un espace annulaire est formé, permettant la mise en contact du produit, contenu dans la réserve, avec la mousse.In Figure 3 we see that the foam cylinder 4a, 4b is held in the box 20 by skirts 25a and 25b, concentric with the cylindrical wall outside of the housing 20. These skirts 25a and 25b are carried by the receptacle 20a and the cover 20b respectively. The skirts are of such height as a space annular is formed, allowing the contacting of the product contained in the reserve, with foam.

    Le cylindre en mousse peut être comprimé axialement, de manière élastique. Le taux de compression est choisi de sorte que la fente présente une étanchéité juste nécessaire pour éviter l'écoulement du produit hors du réservoir. En même temps, l'introduction aisée d'une portion de la mèche, sur laquelle on souhaite appliquer le produit, doit être assurée. Après traitement, la portion de mèche sort de la fente correctement essorée.The foam cylinder can be resiliently compressed axially. The compression ratio is chosen so that the slot has a seal just necessary to prevent the product from flowing out of the tank. Same time, the easy introduction of a portion of the wick, on which one wishes apply the product, must be ensured. After treatment, the wick portion comes out slot wrung out properly.

    Les figures 4 et 5 montrent des vues latérale et frontale respectivement, du dispositif de la figure 3. Sur ces figures, on voit que la fente Q est légèrement évasée sur sa périphérie Q3, favorisant ainsi l'introduction de la portion de mèche à traiter dans le réservoir 2. Dans la partie Q4 entourant le réservoir 2, la fente Q est sensiblement jointive. L'ouverture 22 pratiquée dans le boítier 20 est bordée par une lèvre de guidage 24 en saillie. Le profil de cette lèvre 24 est convergente en direction de la fente Q (voir figure 3, également). La lèvre 24 présente une portion centrale 24a, définissant une zone d'introduction préférentielle, de plus grande largeur.Figures 4 and 5 show side and front views respectively, of the device of Figure 3. In these figures, we see that the slot Q is slightly flared on its periphery Q 3 , thus promoting the introduction of the wick portion to treat in the tank 2. In the part Q 4 surrounding the tank 2, the slot Q is substantially contiguous. The opening 22 made in the housing 20 is bordered by a projecting guide lip 24. The profile of this lip 24 is convergent in the direction of the slot Q (see FIG. 3, also). The lip 24 has a central portion 24a, defining a preferential introduction zone, of greater width.

    La figure 6 montre un mode de réalisation 101, semblable au mode de réalisation des figures 1 et 2. Le boítier 20 de la figure 6 est identique à celui des figures 1 et 2. Le mode de réalisation de la figure 6 se distingue de celui des figures 1 et 2 par le fait que les blocs de mousse 4a et 4b sont de nature différente. Ainsi, la portion 4a est formée d'une mousse dont la taille des cellules et/ou la compressibilité et/ou le matériau constitutif sont différents de la mousse formant la portion 4b.Figure 6 shows an embodiment 101, similar to the embodiment Figures 1 and 2. The housing 20 of Figure 6 is identical to that of Figures 1 and 2. The embodiment of FIG. 6 differs from that of FIGS. 1 and 2 by the fact that the foam blocks 4a and 4b are different in nature. So the portion 4a is formed from a foam whose cell size and / or compressibility and / or the constituent material are different from the foam forming the portion 4b.

    Comme visible sur la figure 7, les blocs de mousse 4a, 4b forment un cylindre plein. Selon l'exemple considéré, les blocs 4a et 4b sont formés chacun d'une mousse de nature différente. La réserve contenant le produit à appliquer est formée, dans ce cas, par les cellules ouvertes des blocs 4a et 4b.As shown in Figure 7, the foam blocks 4a, 4b form a cylinder full. According to the example considered, the blocks 4a and 4b are each formed of a foam of different nature. The reserve containing the product to be applied is formed, in this case, by the open cells of blocks 4a and 4b.

    Sur la figure 8, on voit un dispositif d'application 1a, comportant un boítier 20 semblable à celui illustré sur les figures 1 et 2. Selon le mode de réalisation représenté, l'orifice de remplissage 26 du boítier 20 est monté sur un réservoir auxiliaire externe de produit 30. Ce réservoir externe 30 est formé d'un flacon compressible, constitué d'un matériau thermoplastique approprié, par exemple de polyéthylène, et contenant une réserve important de produit. Le réservoir 30 est surmonté d'un embout de distribution 32 muni d'un adaptateur 34, apte à être mis en communication avec l'orifice de remplissage 26. Dans la configuration illustrée, le réservoir externe 30 et le boítier 20 (muni des moyens d'application 4, 4') forment un ensemble d'application fixe, apte à être alimenté en produit par l'utilisateur à tout moment. Ainsi, par compression du réservoir externe 30, l'utilisateur peut injecter une dose de produit à l'intérieur du boítier 20, en vue de renouveler l'imprégnation des bords 4, 4' de la fente. Dans ce cas, le réservoir externe 30 sert également d'organe de préhension lors de l'application du produit. In Figure 8, we see an application device 1a, comprising a housing 20 similar to that illustrated in FIGS. 1 and 2. According to the embodiment shown, the filling orifice 26 of the housing 20 is mounted on a tank external auxiliary of product 30. This external reservoir 30 is formed by a bottle compressible, made of a suitable thermoplastic material, for example of polyethylene, and containing a large reserve of product. The tank 30 is surmounted by a dispensing nozzle 32 provided with an adapter 34, suitable for being put in communication with the filling orifice 26. In the illustrated configuration, the external reservoir 30 and the housing 20 (provided with application means 4, 4 ') form a fixed application assembly, capable of being supplied with product by the user at any time. Thus, by compression of the external reservoir 30, the user can inject a dose of product inside the housing 20, in order to renew the impregnation of the edges 4, 4 'of the slot. In this case, the tank external 30 also serves as a gripping member during the application of the product.

    La figure 9 illustre un dispositif d'application 1b, comportant un boítier 20 semblable à celui illustré sur les figures 1 et 2. Selon le mode de réalisation représenté, l'orifice de remplissage 26 du boítier 20 est monté sur un manchon de préhension 40. Le manchon 40 peut être amovible, pour permettre d'introduire, au travers de l'orifice de remplissage, une dose de produit à l'intérieur du boítier 20. Après remplissage, le manchon 40 est fixe sur le boítier de manière à obturer ledit orifice de remplissage 26.Figure 9 illustrates an application device 1b, comprising a housing 20 similar to that illustrated in FIGS. 1 and 2. According to the embodiment shown, the filling orifice 26 of the housing 20 is mounted on a sleeve grip 40. The sleeve 40 can be removable, to allow the introduction, at through the filling orifice, a dose of product inside the housing 20. After filling, the sleeve 40 is fixed on the housing so as to close off said filling hole 26.

    La figure 10 illustre un mode de réalisation, particulièrement simple à réaliser, d'un dispositif d'application 201. Selon ce mode de réalisation, un boítier 220 est formé d'un réceptacle inférieur 220c en forme de godet et d'un couvercle 220b. Le réceptacle 220c présente sensiblement la même structure que la moitié inférieure du boítier 20 de la figure 3. A l'intérieur du boítier 220 est disposé un seul cylindre creux 4a en mousse. Le cylindre en mousse 4a forme une surface d'application 4, en contact élastique et étanche avec une portion 4" rigide du couvercle. Ainsi, une fente jointive Q est formée entre la surface 4 en mousse et la portion 4" du bord de couvercle 220b. Avantageusement, le couvercle à un profil interne bombé vers l'extérieur. Ainsi, lorsqu'une portion de mèche est introduite dans la fente Q, de manière à traverser la réserve 2, le produit contenu dans ladite réserve peut imprégner ladite portion de mèche, de façon homogène.FIG. 10 illustrates an embodiment, particularly simple to carry out, of an application device 201. According to this embodiment, a housing 220 is formed of a lower receptacle 220c in the form of a cup and a cover 220b. The receptacle 220c has substantially the same structure as the lower half of the housing 20 of Figure 3. Inside the housing 220 is arranged a single cylinder hollow foam 4a. The foam cylinder 4a forms an application surface 4, in elastic and sealed contact with a rigid 4 "portion of the cover. Thus, a contiguous slot Q is formed between the foam surface 4 and the 4 "portion of the edge cover 220b. Advantageously, the cover has an internal profile curved towards outside. Thus, when a portion of wick is introduced into the slot Q, of so as to cross reserve 2, the product contained in said reserve can impregnate said portion of wick, homogeneously.

    Une portion 222a du réceptacle 220c du boítier est évidée, formant avec une zone 222b correspondante du couvercle 220b une ouverture allongée 22, orientée perpendiculairement à l'axe X. L'ouverture 22 est bordée sur tout son contour d'une lèvre de guidage en deux parties, dont une première partie 24 est solidaire du réceptacle 220c, et dont une seconde partie 24' est solidaire du couvercle 220b.A portion 222a of the receptacle 220c of the housing is hollowed out, forming with an area 222b corresponding to the cover 220b an elongated opening 22, oriented perpendicular to the X axis. The opening 22 is bordered over its entire contour a guide lip in two parts, a first part 24 of which is integral receptacle 220c, and a second part 24 'of which is integral with the cover 220b.

    Selon un mode de réalisation préféré, la figure 11 montre un dispositif 301, en vue partielle, illustrant le montage d'un cylindre en mousse en deux parties 4a, 4b, à l'intérieur d'un boítier 320. Le boítier 320 comporte un corps cylindrique 20a, ouvert à chaque extrémité, chaque extrémité étant fermée par un couvercle correspondant 20b, 20c de forme identique. Le couvercle 20b (20c) comporte une jupe d'étanchéité annulaire 23 dont le diamètre extérieur est légèrement inférieur au diamètre intérieur du corps 20a. Chaque extrémité libre du corps 20a comporte une portion annulaire de plus faible épaisseur, de manière à définir une saillie intérieure 21. La saillie intérieure 21 porte une arête annulaire vive 21a, orientée en direction du couvercle correspondant. Cette arête annulaire 21a peut être continue ou discontinue.According to a preferred embodiment, Figure 11 shows a device 301, in view partial, illustrating the mounting of a foam cylinder in two parts 4a, 4b, to the inside of a case 320. The case 320 has a cylindrical body 20a, open at each end, each end being closed by a cover corresponding 20b, 20c of identical shape. The cover 20b (20c) has a annular sealing skirt 23 whose outside diameter is slightly smaller to the internal diameter of the body 20a. Each free end of the body 20a comprises a thinner annular portion, so as to define a projection inner 21. The inner projection 21 carries a sharp annular edge 21a, oriented towards the corresponding cover. This annular edge 21a can be continuous or discontinuous.

    Lors du montage du boítier 320, le cylindre en mousse 4a, 4b est disposé à l'intérieur du corps 20a. En fixant ensuite chacun des couvercles 20b et 20c sur l'extrémité correspondante du corps 20a, par exemple par claquage, collage ou introduction à force, une portion annulaire de mousse 304a, 304b est pincée entre l'arête 21a et la jupe annulaire 23.When mounting the housing 320, the foam cylinder 4a, 4b is disposed at inside the body 20a. Then fixing each of the covers 20b and 20c on the corresponding end of the body 20a, for example by breakdown, gluing or force introduction, an annular portion of foam 304a, 304b is pinched between the edge 21a and the annular skirt 23.

    Il est bien entendu que, lorsque le cylindre en mousse 4a, 4b est réalisé en une seule pièce, il est suffisant de réaliser sa fixation sur l'une de ses extrémités uniquement. Dans ce cas, le second couvercle, à l'opposé de celui servant à la fixation de la mousse, peut être amovible. Aussi, le second couvercle peut servir de bouchon qu'on enlève pour introduire du produit dans la réserve 2, et que l'on repose après remplissage.It is understood that, when the foam cylinder 4a, 4b is made in one single piece, it is sufficient to fix it on one of its ends only. In this case, the second cover, opposite to that used for the foam attachment, can be removable. Also, the second cover can be used of cap which is removed to introduce product into reserve 2, and which rests after filling.

    Dans la description détaillée qui précède, il a été fait référence à deux modes de réalisation préférés de l'invention. Il est évident que des variantes peuvent y être apportées sans s'écarter de l'invention telle que revendiquée ci-après.In the above detailed description, reference has been made to two modes of preferred embodiments of the invention. Obviously there may be variations made without departing from the invention as claimed below.
