A product, such as a decorative product, can then be applied to this wick. A second part then covers said first part by pressing on it. The device thus moves from an open position in which the lock of hair can be disposed in the device to a closed position in which the lock of hair is held tightly between said first and second portions. A hooking system of the first and second parts of the device is further provided.
  • a disadvantage related to the devices of the prior art is related to their configuration and their mode of use.

Abstract

The device has two parts (1, 2) displaceable between open and closed positions. The parts are in face to face in the closed position to extend the parts on both sides of a hair lock. A spacing unit (3) remotely maintains the parts in the closed position. The spacing unit and the parts define a channel (4) open at an end, where the channel receives the hair lock. The unit forms a support surface on which the parts lie, and includes ribs located remotely from one another. The unit and the parts are made of leakage proof material such as polymeric foam with closed cells. An independent claim is also included for a method for applying a product on a hair lock.

Description

La présente invention concerne un dispositif pour isoler au moins une mèche de cheveux et un procédé d'application d'un produit sur une mèche de cheveux. Le produit peut être un produit cosmétique tel qu'un produit de coloration directe ou indirecte ou un produit de décoloration. Par « produit cosmétique », on entend un produit tel que défini dans la Directive 93/35/CEE du Conseil du 14 juin 1993.The present invention relates to a device for isolating at least one lock of hair and a method of applying a product to a lock of hair. The product may be a cosmetic product such as a direct or indirect coloring product or a decolorization product. "Cosmetic product" means a product as defined in Council Directive 93/35 / EEC of 14 June 1993.

Des domaines d'application privilégiés, mais non exclusifs, de la présente invention sont donc la coloration et la décoloration capillaire.Preferred, but not exclusive, fields of application of the present invention are thus coloring and capillary decolorization.

De nombreux dispositifs permettant d'isoler des mèches de cheveux dans le but de réaliser une coloration ou une décoloration capillaire des mèches de cheveux isolées sont répertoriés dans l'art antérieur.Numerous devices for isolating strands of hair in order to achieve a coloration or hair discoloration of isolated locks of hair are listed in the prior art.

Le documents US-4,144,897 , US-4,942,893 , US-5,228,465 , US-5,845,653 , et FR 2,857,236 divulguent des exemples de dispositif pour sélectivement isoler des mèches de cheveux pour leur faire subir un traitement tel qu'une coloration ou une décoloration.The documents US 4144897 , US 4942893 , US 5228465 , US 5845653 , and FR 2,857,236 disclose device examples for selectively isolating locks of hair for treatment such as staining or bleaching.

Le document US-4,144,897 divulgue en particulier un dispositif réalisé en deux parties aptes à être déplacées entre une position ouverte et une position fermée. En position ouverte, ce dispositif est adapté à recevoir une mèche de cheveux à traiter. La mèche de cheveux est ainsi placée sur une première partie du dispositif. Un produit, tel qu'un produit de décoration, peut ensuite être appliqué sur cette mèche. Une seconde partie vient ensuite recouvrir ladite première partie en se plaquant dessus. Le dispositif passe donc d'une position ouverte dans laquelle la mèche de cheveux peut être disposée dans le dispositif à une position fermée dans laquelle la mèche de cheveux est retenue de façon serrante entre lesdites première et seconde parties. Un système d'accrochage des première et seconde parties du dispositif est en outre prévu.The document US 4144897 discloses in particular a device made in two parts able to be moved between an open position and a closed position. In the open position, this device is adapted to receive a lock of hair to be treated. The lock of hair is thus placed on a first part of the device. A product, such as a decorative product, can then be applied to this wick. A second part then covers said first part by pressing on it. The device thus moves from an open position in which the lock of hair can be disposed in the device to a closed position in which the lock of hair is held tightly between said first and second portions. A hooking system of the first and second parts of the device is further provided.

Un inconvénient lié aux dispositifs de l'art antérieur est lié à leur configuration et leur mode d'utilisation.A disadvantage related to the devices of the prior art is related to their configuration and their mode of use.

En effet, un tel dispositif est destiné à être positionné fixement sur la tête de l'utilisateur avec la mèche de cheveux retenue en prise serrante à l'intérieur du dispositif. Les moyens d'accrochage assurent alors le maintien du dispositif en position fermée et l'ancrage sur la tête de l'utilisateur. Cependant, le poids du dispositif peut créer un tirage important sur la racine des cheveux de l'utilisateur.Indeed, such a device is intended to be fixedly positioned on the head of the user with the lock of hair held tightly within the device. The attachment means then ensure the maintenance of the device in the closed position and the anchoring on the head of the user. However, the weight of the device can create a large draw on the user's hairline.

En outre un tel dispositif de l'art antérieur est particulièrement inapproprié pour réaliser un traitement capillaire sur des mèches de cheveux de grande longueur. En effet, pour réaliser un tel traitement, l'utilisateur devrait s'y reprendre à plusieurs fois pour traiter toute la longueur de la mèche de cheveux. Pour ce faire l'utilisateur devrait refermer le dispositif sur une première longueur de mèche, attendre que cette première longueur de mèche s'imprègne de produit puis ouvrir le dispositif, le refermer sur une deuxième longueur de mèche de cheveux, attendre que cette deuxième longueur de mèche s'imprègne de produit et ainsi de suite jusqu'à ce que toute la longueur de la mèche soit imprégnée de produit. Ainsi la mise en oeuvre de tels dispositifs s'avère particulièrement fastidieuse et ne peut être réalisée seule par l'utilisateur, ce dernier nécessitant l'aide d'une tierce personne pour traiter uniformément chaque mèche de cheveux.In addition, such a device of the prior art is particularly inappropriate for performing a hair treatment on locks of long hair. Indeed, to achieve such treatment, the user should take several times to treat the entire length of the lock of hair. To do this the user should close the device on a first wick length, wait for this first wick length impregnates product and then open the device, close it on a second length of lock of hair, wait for this second length wick impregnates product and so on until the entire length of the wick is impregnated with product. Thus the implementation of such devices is particularly tedious and can not be performed alone by the user, the latter requiring the help of a third person to treat each strand of hair uniformly.

Autrement, ce document prévoit tout de même d'adapter la taille du dispositif à la longueur des cheveux de l'utilisateur. Toutefois, cette solution s'avère particulièrement inappropriée pour des utilisateurs présentant des cheveux de grande taille puisqu'elle risque d'alourdir encore plus le poids du dispositif et de créer ainsi un tirage encore plus important sur la racine des cheveux.Otherwise, this document still provides to adapt the size of the device to the length of the hair of the user. However, this solution is particularly inappropriate for users with large hair since it may increase the weight of the device even more and thus create an even greater draw on the hairline.

Un but de la présente invention est donc de fournir un dispositif et un procédé d'isolement de mèches de cheveux surmontant les inconvénients de l'art antérieur.An object of the present invention is therefore to provide a device and a method of isolating locks of hair overcoming the drawbacks of the prior art.

Un autre but de la présente invention est encore de fournir un dispositif et un procédé d'isolement de mèche de cheveux s'adaptant aisément à toute longueur de cheveux.Another object of the present invention is still to provide a device and a method of isolating a lock of hair easily adapting to any length of hair.

Un but de la présente invention est encore de fournir un dispositif de fabrication et de mise en oeuvre simple, présentant un coût de revient faible.An object of the present invention is still to provide a device for manufacturing and simple implementation, with a low cost.

La présente invention a également pour but de fournir un dispositif et un procédé que l'utilisateur pourra lui-même utiliser, sans avoir à faire appel à une tierce personne, tout en garantissant un résultat de coloration ou de décoloration particulièrement uniforme.The present invention also aims to provide a device and a method that the user can use himself, without having to appeal to a third person, while ensuring a particularly uniform coloring or fading result.

La présente invention a donc pour objet un dispositif pour isoler au moins une mèche de cheveux sur laquelle un produit peut être appliqué, ledit dispositif comprenant au moins une première partie et une seconde partie déplaçables entre une position ouverte et une position fermée, en position fermée lesdites première et seconde parties venant en vis-à-vis de manière à s'étendre de part et d'autre de ladite au moins une mèche de cheveux, dans lequel ledit dispositif comporte en outre des moyens d'espacement configurés pour maintenir à distance lesdites première et seconde parties en position fermée, lesdits moyens d'espacement définissant ensemble avec lesdites première et seconde parties un canal ouvert à au moins une extrémité destiné à recevoir ladite mèche de cheveux. Ainsi, en position fermée du dispositif, le canal formé grâce aux moyens d'espacement évite de prendre en prise serrante ladite mèche de cheveux. En effet, dans ce cas, la mèche de cheveux peut être disposé lâche dans le dispositif en position fermée. Une telle configuration permet ainsi de déplacer le dispositif relativement à la mèche de cheveux sans exercer un tirage excessif des cheveux.The present invention therefore relates to a device for isolating at least one lock of hair on which a product can be applied, said device comprising at least a first portion and a second portion movable between an open position and a closed position, in the closed position said first and second portions facing each other so as to extend on either side of said at least one lock of hair, wherein said device further comprises spacing means configured to hold at a distance said first and second portions in a closed position, said spacing means defining together with said first and second portions an open channel at at least one end for receiving said lock of hair. Thus, in the closed position of the device, the channel formed by the spacing means avoids gripping said lock of hair. Indeed, in this case, the lock of hair can be loosely arranged in the device in the closed position. Such a configuration thus makes it possible to move the device relative to the lock of hair without exerting an excessive pull of the hair.

Ledit canal peut être ouvert à deux extrémités, et ce d'une extrémité à l'autre. Ces deux extrémités peuvent être axialement opposées l'une par rapport à l'autre. Lesdites première et seconde parties peuvent comprendre chacune un bord inférieur et un bord supérieur opposé, en position fermée le bord inférieur et le bord supérieur de la première partie étant respectivement espacés du bord inférieur et du bord supérieur de la seconde partie, lesdits bords supérieurs et inférieurs desdites première et seconde parties définissant au moins en partie les ouvertures dudit canal. En position fermée, le dispositif peut comprendre un côté de grande dimension, ou longueur, et un côté de moindre dimension, ou largeur, lesdits moyens d'espacement s'étendant le long du côté de grande dimension. Autrement dit, lesdits moyens d'espacement peuvent s'étendre dans la longueur du dispositif. Ces moyens d'espacement peuvent s'étendre de façon adjacente ou à distance de ce côté de grande dimension. En particulier, lesdits moyens d'espacement peuvent s'étendre parallèlement au côté de grande dimension. Les deux côtés opposés de moindre dimension du dispositif peuvent définir les ouverture du canal.Said channel can be open at two ends, and from one end to the other. These two ends may be axially opposite to each other. Said first and second parts may each comprise a lower edge and an opposite upper edge, in the closed position on lower edge and the upper edge of the first portion being respectively spaced from the lower edge and the upper edge of the second portion, said upper and lower edges of said first and second portions defining at least in part the openings of said channel. In the closed position, the device may comprise a large dimension side, or length, and a smaller dimension side, or width, said spacing means extending along the large dimension side. In other words, said spacing means may extend in the length of the device. These spacing means may extend adjacent to or away from this large dimension. In particular, said spacing means may extend parallel to the large side. The two opposite sides of smaller dimension of the device can define the opening of the channel.

Ledit canal peut être latéralement délimité d'une part par lesdits moyens d'espacement et d'autre part par une portion formant articulation entre lesdites première et deuxième parties ou par d'autres moyens d'espacement. Ainsi, la mèche de cheveux peut être reçue dans un espace délimité par les faces internes respectives des première et deuxième parties et au moins deux moyens d'espacement prévus distants l'un de l'autre. La mèche de cheveux peut également être reçu dans un espace délimité par les faces internes respectives des première et deuxième parties, des moyens d'espacement et une portion formant articulation entre lesdites première et deuxième parties.Said channel may be laterally delimited on the one hand by said spacing means and on the other hand by a hinge portion between said first and second parts or by other spacing means. Thus, the lock of hair can be received in a space delimited by the respective inner faces of the first and second parts and at least two spacing means provided spaced apart from each other. The lock of hair may also be received in a space delimited by the respective inner faces of the first and second parts, spacing means and a portion forming a hinge between said first and second parts.

Lesdites première et deuxième parties peuvent chacune présenter une face interne respective venant en regard l'une de l'autre en position fermée, ces faces internes étant espacées l'une de l'autre sur une distance allant au moins des moyens d'espacement jusqu'à d'autres moyens d'espacement et/ou jusqu'à une portion formant articulation entre lesdites première et deuxième parties.Said first and second parts may each have a respective inner face facing each other in the closed position, these internal faces being spaced apart from each other over a distance of at least spacing means up to to other spacing means and / or to a hinge portion between said first and second portions.

En position fermée, les première et seconde parties peuvent définir entre elles un angle non nul, de préférence compris entre 5 et 90°.In the closed position, the first and second parts can define between them a non-zero angle, preferably between 5 and 90 °.

Ledit canal peut former une glissière apte à confiner ladite au moins une mèche de cheveux. Une telle glissière permet d'une part de calibrer la mèche de cheveux à isoler et d'autre part forme un rail de guidage facilitant le déplacement du dispositif relativement à ladite mèche de cheveux.Said channel may form a slide capable of confining said at least one lock of hair. Such a slide allows on the one hand to calibrate the wick of hair to isolate and secondly forms a guide rail facilitating movement of the device relative to said lock of hair.

Lesdits moyens d'espacement peuvent être solidaires de la première face et/ou de la deuxième face. Lesdits moyens d'espacement peuvent ainsi être fixés à la première et/ou la seconde face, tel que par collage, par des moyens de fixation à boucles et crochets du type Velcro, etc. Ils peuvent être alternativement réalisés monobloc avec la première et/ou la seconde partie.Said spacing means may be integral with the first face and / or the second face. Said spacing means can thus be fixed to the first and / or second face, such as by gluing, by Velcro-type hook and loop fastening means, etc. They can alternatively be made in one piece with the first and / or second part.

Lesdits moyens d'espacement peuvent former une surface d'appui sur laquelle vient reposer la première partie et/ou la seconde partie.Said spacing means may form a bearing surface on which comes to rest the first part and / or the second part.

Lesdits moyens d'espacement peuvent s'étendre dans une direction longitudinale de ladite première partie et/ou de ladite seconde partie.Said spacing means may extend in a longitudinal direction of said first portion and / or said second portion.

Lesdits moyens d'espacement peuvent s'étendre sur toute la longueur de ladite première partie et/ou de ladite seconde partie.Said spacing means may extend over the entire length of said first portion and / or said second portion.

Lesdites première et seconde parties peuvent être articulées autour d'un axe de rotation.Said first and second parts can be articulated about an axis of rotation.

Lesdits moyens d'espacement peuvent s'étendre à distance dudit axe de rotation.Said spacing means may extend at a distance from said axis of rotation.

Lesdits moyens d'espacement peuvent s'étendre parallèlement audit axe de rotation.Said spacing means may extend parallel to said axis of rotation.

Lesdits moyens d'espacement peuvent comprendre au moins deux nervures, situées à distance l'une de l'autre.Said spacing means may comprise at least two ribs, located at a distance from one another.

Lesdites deux nervures peuvent s'étendre parallèlement l'une par rapport à l'autre.Said two ribs may extend parallel to one another.

Lesdites première et seconde parties peuvent être réalisées monobloc. Dans ce cas, ledit axe de rotation peut s'étendre au niveau d'une ligne de pliage séparant, de préférence de façon sensiblement médiane, lesdites première et seconde parties. Ladite ligne de pliage peut s'étendre au niveau d'une portion de moindre épaisseur.Said first and second parts can be made in one piece. In this case, said axis of rotation may extend at a fold line separating, preferably substantially median, said first and second parts. Said fold line may extend at a portion of lesser thickness.

Lesdits moyens d'espacement et lesdites première et seconde parties peuvent être réalisés en un matériau étanche au produit à appliquer, de préférence réalisée en une mousse polymérique à cellules fermées.Said spacing means and said first and second parts may be made of a material impervious to the product to be applied, preferably made of a closed cell polymeric foam.

La présente invention a également pour objet un procédé d'application d'un produit sur une mèche de cheveux comprenant les étapes de :

  • fournir un dispositif selon l'une quelconque des revendications précédentes,
  • appliquer un produit, tel qu'un produit de coloration, sur ladite première partie et/ou ladite seconde partie,
  • disposer une mèche de cheveux entre lesdites première et seconde parties en position ouverte,
  • fermer ledit dispositif,
  • faire coulisser ledit dispositif relativement à ladite mèche de cheveux.
The present invention also relates to a method of applying a product to a lock of hair comprising the steps of:
  • providing a device according to any one of the preceding claims,
  • applying a product, such as a coloring product, to said first part and / or said second part,
  • arranging a lock of hair between said first and second parts in the open position,
  • close said device,
  • slide said device relative to said lock of hair.

Ladite mèche de cheveux à traiter peut s'étendre exclusivement entre les moyens d'espacement et une portion formant articulation entre lesdites première et deuxième parties.Said lock of hair to be treated may extend exclusively between the spacing means and a portion forming a joint between said first and second parts.

Ladite mèche de cheveux à traiter peut s'étendre selon un axe d'allongement du canal.Said lock of hair to be treated may extend along an axis of elongation of the channel.

Ladite mèche de cheveux à traiter peut s'étendre selon une direction générale sensiblement parallèle aux moyens d'espacement.Said lock of hair to be treated may extend in a general direction substantially parallel to the spacing means.

Lesdits moyens d'espacement peuvent former des moyens de guidage latéraux de ladite mèche de cheveux lors du coulissement du dispositif.Said spacing means can form lateral guiding means of said lock of hair during sliding of the device.

Lesdits moyens d'espacement peuvent s'étendre de façon parallèle à ladite mèche de cheveux à disposer entre lesdites première et seconde parties.Said spacing means may extend parallel to said lock of hair to be disposed between said first and second portions.

The invention will be better understood on reading the following detailed description, made with reference to the accompanying drawings illustrating a non-limiting embodiment thereof, and in which:
  • FIG. 1 is a schematic perspective view from above of an embodiment of a device according to the present invention in open position,

En référence aux figures 1 à 6 qui représentent différents modes de réalisation de la présente invention, le dispositif selon la présente invention comporte une première partie et une seconde parties déplaçables entre une position ouverte représentée sur la figure 1 et une position fermée représentée sur la figure 2.Referring to FIGS. 1 to 6 which show various embodiments of the present invention, the device according to the present invention comprises a first part and a second part movable between an open position shown in FIG. 1 and a closed position shown in FIG. 2.

Les première et seconde parties comprennent chacune une face interne 10, 20 et une face externe 15, 25.The first and second parts each comprise an inner face 10, 20 and an outer face 15, 25.

Les faces internes 10, 20 sont destinées à être recouvertes d'un produit, tel qu'un produit de traitement capillaire du type colorant ou décolorant. Ces faces internes définissent ainsi une surface d'application de produit. Cette surface d'application est délimitée par un bord inférieur respectivement 11, 21, un bord supérieur opposé respectivement 12, 22, lesdits bords inférieur et supérieur étant reliés ensemble par des bords longitudinaux extérieurs et intérieurs respectivement 13, 14 et 23, 24. En position fermée, les bords longitudinaux extérieurs et intérieurs forment des cotés respectifs de grande dimension du dispositif tandis que les bords inférieur et supérieur forment des côtés de moindre dimension de ce dispositif.The inner faces 10, 20 are intended to be covered with a product, such as a hair treatment product of the dye or bleaching type. These inner faces thus define a product application surface. This application surface is delimited by a lower edge respectively 11, 21, an opposite upper edge respectively 12, 22, said upper and lower edges being connected together by outer and inner longitudinal edges respectively 13, 14 and 23, 24. In closed position, the outer and inner longitudinal edges form respective large dimensions of the device while the lower and upper edges form smaller dimensions of this device.

Les faces externes 15, 25 sont quant à elles destinées à être saisies par l'utilisateur pour manier le dispositif.The outer faces 15, 25 are for their part intended to be entered by the user to handle the device.

Dans le présent exemple de réalisation, la première partie et la seconde partie sont de configuration identique. Ces première et seconde parties peuvent ainsi chacune être de configuration générale de prisme droit ou non droit à base polyédrique. Plus précisément, ces première et seconde parties peuvent présenter comme visible sur les figures une configuration générale de parallélépipède rectangle. Dans ce cas, la face interne 10, 20 définit donc une surface d'application de forme rectangulaire. Dans le présent exemple de réalisation, les bords longitudinaux extérieurs 13, 23 s'étendent de façon parallèle aux bords longitudinaux intérieurs 14, 24. De même, les bords supérieurs 12, 22 s'étendent de façon parallèle aux bords inférieurs 11, 21. Bien entendu, les première et seconde parties pourraient présenter une configuration générale autre et une surface d'application de forme tout à fait différente. Par exemple, les première et seconde parties pourraient présenter une configuration de calotte ayant une surface d'application de forme circulaire, de configuration tronconique ayant une surface d'application de forme circulaire, de prisme à base triangulaire ayant une surface d'application rectangulaire, de prisme à base trapézoïdale ayant une surface d'application trapézoïdale, ou encore de pyramide tronquée ayant une surface d'application rectangulaire.In the present exemplary embodiment, the first part and the second part are of identical configuration. These first and second parts can each be of general configuration of right prism or not right polyhedral base. More specifically, these first and second parts may have as visible in the figures a general configuration of rectangular parallelepiped. In this case, the inner face 10, 20 thus defines an application surface of rectangular shape. In the present embodiment, the outer longitudinal edges 13, 23 extend parallel to the inner longitudinal edges 14, 24. Likewise, the upper edges 12, 22 extend parallel to the lower edges 11, 21. Of course, the first and second parts could have a general configuration other and an application surface of quite different shape. For example, the first and second portions could have a cap configuration having a circularly shaped, frusto-conically shaped application surface having a circularly shaped, triangular-based prismatic surface having a rectangular application surface, a trapezoidal prism having a trapezoidal application surface, or a truncated pyramid having a rectangular application surface.

Cette première et cette seconde partie peuvent également présenter des dimensions similaires. En particulier, les première et seconde parties peuvent chacune présenter des bord inférieur 11, 21 et supérieur 12, 22 d'une dimension avantageusement comprise entre 5 et 12 cm et des bords longitudinaux extérieur 13, 23 et intérieur 14, 24 d'une dimension avantageusement comprise entre 5 et 20 cm.This first and second part may also have similar dimensions. In particular, the first and second parts may each have lower edge 11, 21 and upper 12, 22 of a dimension advantageously between 5 and 12 cm and outer longitudinal edges 13, 23 and inner 14, 24 of a dimension advantageously between 5 and 20 cm.

Avantageusement ces première et seconde parties sont réalisées en un matériau polymérique. De préférence, le matériau polymérique est un matériau se présentant sous forme d'une mousse à cellules fermées. Une telle mousse peut être obtenue par découpe, thermo-compression ou de préférence par extrusion. Dans ce dernier cas, une filière d'extrusion est fabriquée à la forme voulue. Au final, pour le mode de réalisation représenté, une forme de plaque est obtenue qui est par la suite découpée à la dimension voulue. L'utilisation d'une telle mousse à cellules fermées rend ainsi lesdites première et seconde parties étanches au produit. Ainsi, l'utilisateur ne risque pas de se souiller les doigts suite à l'application d'un produit sur la surface d'application du dispositif et à son maniement. Il est également possible d'utiliser un matériau quelconque, alvéolaire ou non, comme de la mousse de polyéthylène à cellule ouverte, recouvert d'une couche imperméable comme du film plastique ou du tissu ou bien un élastomère thermoplastique injecté, ou encore un thermoplastique thermoformé. Les première et/ou seconde parties peuvent également être réalisées en un matériau élastiquement déformable.Advantageously these first and second parts are made of a polymeric material. Preferably, the polymeric material is a material in the form of a closed cell foam. Such a foam can be obtained by cutting, thermo-compression or preferably by extrusion. In the latter case, an extrusion die is made to the desired shape. Finally, for the embodiment shown, a plate shape is obtained which is subsequently cut to the desired size. The use of such a closed cell foam thus renders said first and second parts tight to the product. Thus, the user is not likely to soil his fingers following the application of a product on the application surface of the device and its handling. It is also possible to use any material, cellular or not, such as open cell polyethylene foam, covered with an impermeable layer such as plastic film or fabric or an injected thermoplastic elastomer, or a thermoformed thermoplastic . The first and / or second parts may also be made of an elastically deformable material.

De préférence, ces première et seconde parties sont articulées ensemble autour d'un axe de rotation X. Cet axe de rotation X se situe à distance des bords longitudinaux extérieurs 13, 23 des première et seconde parties. Selon un mode de réalisation, cet axe de rotation X s'étend parallèlement aux bords longitudinaux des première et secondes parties. Lorsque les première et seconde parties sont de configuration et de dimension identiques, cet axe de rotation X peut définir en position ouverte un axe de symétrie. Un tel axe de symétrie est notamment obtenu lorsque les première et seconde parties s'étendent dans un même plan.Preferably, these first and second parts are articulated together about an axis of rotation X. This axis of rotation X is located at a distance from the outer longitudinal edges 13, 23 of the first and second parts. According to one embodiment, this axis of rotation X extends parallel to the longitudinal edges of the first and second parts. When the first and second parts are of identical configuration and dimension, this axis of rotation X can define in the open position an axis of symmetry. Such an axis of symmetry is obtained especially when the first and second parts extend in the same plane.

Comme visible sur les figures, les première et seconde parties peuvent être réalisées monobloc. Dans un tel cas, l'axe de rotation X s'étend au niveau d'une ligne de pliage. Cette ligne de pliage s'étend au niveau des bords longitudinaux intérieurs 14, 24 desdites première et seconde parties. Dans le présent exemple, étant donné que les première et seconde parties présentent une dimension identique cette ligne de pliage coupe ledit dispositif en son milieu. Cette ligne de pliage est formée par une charnière film. Cette charnière film est avantageusement formée par une découpe à mi-chair du matériau. Elle peut aussi être constituée par une portion de moindre épaisseur du dispositif.As shown in the figures, the first and second parts can be made in one piece. In such a case, the axis of rotation X extends at a fold line. This fold line extends at the inner longitudinal edges 14, 24 of said first and second portions. In the present example, since the first and second portions have an identical dimension, this fold line intersects said device in its middle. This fold line is formed by a film hinge. This film hinge is advantageously formed by a cut at half-flesh of the material. It may also consist of a smaller portion of the device.

Tel que représenté sur la figure 2, la seconde partie 2 peut être déplacée en rotation autour de l'axe X de façon à définir ensemble avec ladite première partie 1 une position fermée. Autrement dit, la seconde partie 2 est rabattue sur la première partie 1. Dans cette position fermée, la seconde face 20 est alors placée en vis-à-vis de la première face 10. Dans le présent exemple de réalisation, le bord longitudinal extérieur 23 de la seconde partie 2 se place en vis-à-vis du bord longitudinal extérieur 13 de la première partie 1. Des moyens de fermeture, tel qu'un système à boucle et crochet du type Velcro, pourraient être prévus afin de verrouiller ce dispositif en position fermée. De tels moyens pourraient par exemple s'étendre le long des bords longitudinaux externes des première et seconde parties.As shown in Figure 2, the second portion 2 can be rotated about the axis X so as to define together with said first portion 1 a closed position. In other words, the second part 2 is folded over the first part 1. In this closed position, the second face 20 is then placed vis-à-vis the first face 10. In the present embodiment, the outer longitudinal edge 23 of the second part 2 is placed vis-à-vis the outer longitudinal edge 13 of the first part 1. Closing means, such as a hook and loop system Velcro type could be provided to lock this device in closed position. Such means could for example extend along the outer longitudinal edges of the first and second parts.

Selon l'invention, le dispositif comporte en outre des moyens d'espacement 3 qui sont configurés pour maintenir à distance lesdites première et seconde parties lorsque ces dernières sont en position fermée. Ces première et seconde parties définissent alors intérieurement un canal 4. Les faces internes 10, 20 des première et seconde parties sont à distance l'une de l'autre au moins entre les moyens d'espacement 3 et la portion formant articulation entre lesdites première et seconde parties. Plus précisément, les première et seconde parties sont espacés l'une de l'autre sur toute la distance située entre les moyens d'espacement et ladite portion formant articulation. Ces faces internes sont ainsi espacées l'une de l'autre que ce soit à proximité des moyens d'espacement ou à distance des moyens d'espacement. Comme il sera davantage expliqué dans la suite de cette description, lesdites première et deuxième parties peuvent être maintenues espacées l'une de l'autre sur une distance allant au moins des moyens d'espacement jusqu'à d'autres moyens d'espacement, si ceux-ci sont prévus, et/ou jusqu'à ladite portion formant articulation. Ce canal est donc ouvert sur toute sa largeur, allant des moyens d'espacement jusqu'à la portion formant articulation. De tels moyens d'espacement 3 peuvent donc éviter que les première et seconde parties viennent l'une et l'autre en contact sur sensiblement toute la surface de leurs faces internes 10, 20. Ainsi, en l'absence ou en présence d'une mèche de cheveux s'étendant entre les première et seconde parties, la face interne 20 de la seconde partie ne viendra pas totalement se plaquer contre la face interne 10 de la seconde partie, un canal de préférence longitudinal traversant de part et d'autre lesdites première et seconde parties étant formés grâce aux moyens d'espacement.According to the invention, the device further comprises spacing means 3 which are configured to keep said first and second parts at a distance when they are in the closed position. These first and second parts then internally define a channel 4. The inner faces 10, 20 of the first and second parts are at a distance from each other at least between the spacing means 3 and the portion forming articulation between said first and second parts. and second parts. More specifically, the first and second parts are spaced apart from each other over the entire distance between the spacing means and said articulation portion. These inner faces are thus spaced apart from each other either near the spacing means or at a distance from the spacing means. As will be explained further in the following of this description, said first and second portions may be spaced apart from each other at a distance of at least spacing means to other spacing means, if provided, and / or to said portion forming articulation. This channel is thus open over its entire width, from spacing means to the joint portion. Such spacing means 3 can thus prevent the first and second parts from coming into contact with each other on substantially the entire surface of their internal faces 10, 20. Thus, in the absence or in the presence of a strand of hair extending between the first and second parts, the inner face 20 of the second part will not fully press against the inner face 10 of the second part, a preferably longitudinal channel crossing on either side said first and second portions being formed by the spacing means.

Le canal 4 formé entre lesdites première et seconde parties permet ainsi de définir en position fermée une ouverture destinée à la réception d'une mèche de cheveux. Cette ouverture permet à la mèche de cheveux disposée à l'intérieur de ne pas être nécessairement maintenue en prise serrante dans le dispositif en position fermée. Autrement dit, ces moyens d'espacement permettent d'obtenir en position fermée un angle α non nul entre les première et seconde parties au niveau de la ligne de pliage. Un tel angle évite alors de coincer des cheveux entre lesdites première et seconde parties au niveau de cette ligne de pliage. Cet angle peut par exemple être compris entre 5 et 40°. Ainsi, si le dispositif doit être déplacé relativement à la mèche de cheveux saisie, la présente invention évite de tirer sur des cheveux qui seraient coincés à hauteur de la ligne de pliage et évite ainsi d'occasionner des douleurs à l'utilisateur. L'ouverture définie par le canal peut présenter une section transversale de toutes formes possibles telles que sensiblement triangulaire, carrée, rectangulaire, trapézoïdale etc. Le canal peut être ouvert sur toute sa longueur. Autrement dit ce canal peut être ouvert d'une extrémité à l'autre. De même, Le canal est également de préférence ouvert sur toute sa largeur, c'est-à-dire des moyens d'espacement jusqu'à ladite portion formant articulation entre lesdites première et deuxième parties. En position fermée du dispositif, l'ouverture du canal peut par exemple présenter un espacement entre lesdites première et deuxième parties, ou hauteur, d'au moins 5 mm, par exemple compris entre 5 mm et 3 cm et plus avantageusement entre 8 mm et 2 cm. Ce canal peut présenter une section transversale constante sur toute sa longueur ou variable. Plus particulièrement, l'espacement entre les faces internes respectives des première et seconde parties venant en vis-à-vis peut être sensiblement constant sur toute la longueur du canal. L'espacement entre les moyens d'espacement et la portion formant articulation entre lesdites première et deuxième parties peut quant à lui être variable.The channel 4 formed between said first and second parts thus makes it possible to define in the closed position an opening intended to receive a lock of hair. This opening allows the lock of hair arranged inside to not necessarily be held in tight grip in the closed position. In other words, these spacing means make it possible to obtain in the closed position a non-zero angle α between the first and second parts at the level of the fold line. Such an angle avoids pinching hair between said first and second portions at this fold line. This angle may for example be between 5 and 40 °. Thus, if the device is to be moved relative to the lock of hair seized, the present invention avoids pulling hair that would be stuck at the height of the fold line and thus avoid causing pain to the user. The opening defined by the channel may have a cross section of all possible shapes such as substantially triangular, square, rectangular, trapezoidal, etc. The channel can be opened along its entire length. In other words, this channel can be opened from one end to the other. Similarly, the channel is also preferably open over its entire width, that is to say spacing means to said hinge portion between said first and second parts. In the closed position of the device, the opening of the channel may for example have a spacing between said first and second parts, or height, of at least 5 mm, for example between 5 mm and 3 cm and more advantageously between 8 mm and 2 cm. This channel may have a constant cross section over its entire length or variable. More particularly, the spacing between the respective inner faces of the first and second parts coming vis-à-vis may be substantially constant over the entire length of the channel. The spacing between the spacer means and the hinge portion between said first and second parts may be variable.

En position fermée, de tels moyens d'espacement forment donc une surface d'appui sur laquelle vient reposer la partie à rabattre du dispositif. Avantageusement, le canal formé est ouvert à ses deux extrémités. Les ouvertures du canal sont alors avantageusement définies par les bords supérieurs et inférieurs desdites première et seconde parties. Ainsi, en position fermée, le bord inférieur 11 et le bord supérieur 12 de la première partie 1 sont respectivement espacés du bord inférieur 21 et du bord supérieur 22 de ladite seconde partie 2.In the closed position, such spacing means thus form a bearing surface on which comes to rest the part to be folded down from the device. Advantageously, the formed channel is open at both ends. The openings of the channel are then advantageously defined by the upper and lower edges of said first and second parts. Thus, in the closed position, the lower edge 11 and the upper edge 12 of the first part 1 are respectively spaced from the lower edge 21 and the upper edge 22 of said second part 2.

Le canal est par ailleurs fermé latéralement d'une part par les moyens d'espacement 3 et d'autre part par la portion formant articulation desdites première et deuxième parties. Comme il sera davantage exmpliqué par la suite, la mèche de cheveux à traiter est disposé entre les moyens d'espacement 3 et la portion formant articulation entre les première et deuxième parties du dispositif. Selon la longueur de la mèche traitée, la mèche pourra s'étendre au travers d'une seule extrémité ouverte du dispositif, côté cuir chevelu, ou comme représenté au travers des deux extrémités ouvertes.The channel is also closed laterally on the one hand by the spacer means 3 and on the other hand by the hinge portion of said first and second parts. As will be further explained later, the lock of hair to be treated is disposed between the spacer means 3 and the hinge portion between the first and second parts of the device. Depending on the length of the treated wick, the wick may extend through a single open end of the device, on the scalp side, or as shown through both open ends.

Les moyens d'espacement 3 sont solidaires de ladite première partie et/ou de ladite seconde partie. Autrement dit, ces moyens d'espacement peuvent être prévus seulement sur la première partie, seulement sur la seconde partie ou à la fois sur la première partie et sur la seconde partie. De tels moyens d'espacement peuvent être rapportés et fixés sur la première partie par tous moyens appropriés, tel que par collage, ou peuvent être réalisés monobloc avec ladite première partie. Ces moyens d'espacement sont de préférence réalisés en un matériau étanche au produit de sorte que les moyens d'espacement confinent le produit appliqué. En particulier, les moyens d'espacement peuvent être réalisés sous forme d'une mousse à cellules fermées en un matériau identique ou distinct à celui mis en oeuvre pour la réalisation des première et seconde parties.The spacing means 3 are integral with said first portion and / or said second portion. In other words, these spacing means can be provided only on the first part, only on the second part or both on the first part and on the second part. Such spacing means can be attached and fixed on the first part by any appropriate means, such as by gluing, or can be made in one piece with said first part. These spacing means are preferably made of a product-tight material so that the spacing means confines the applied product. In particular, the spacing means may be made in the form of a closed-cell foam made of a material identical to or different from that used for producing the first and second parts.

Par ailleurs, tel qu'il sera mieux compris dans la suite de cette description, les moyens d'espacement forment avantageusement des moyens de calibrage de la (des) mèche(s) saisie(s) et en outre définissent une glissière dans laquelle ladite mèche de cheveux peut aisément coulisser.Furthermore, as will be better understood in the rest of this description, the spacing means advantageously form means for calibrating the seized bit (s) and further define a slide in which said lock of hair can easily slide.

Les moyens d'espacement peuvent se présenter sous la forme d'une ou plusieurs nervures. Cette nervure présente dans les exemples de réalisations représentés une section transversale de forme rectangulaire. Une telle nervure forme avec la partie à partir de laquelle elle fait saillie un créneau. Toutefois, cette nervure pourrait présenter une section transversale de forme différente telle qu'une section carrée, triangulaire, tronconique ou hémisphérique. Par ailleurs, lorsque les moyens d'espacement comprennent plusieurs nervures, ces dernières peuvent présenter des formes et des dimensions différentes. Dans ces différents cas, ces moyens d'espacement 3 forment une surépaisseur apte à éloigner au moins en position fermée la seconde partie 2 de la première partie 1. Cependant, il est à noter que les moyens d'espacement pourraient être formés autrement que par une nervure. Par exemple, la seconde partie pourrait présenter une configuration convexe tandis que la première partie pourrait être de forme plane ou concave, ou inversement. Les première et seconde parties pourraient alors définir entre elles un canal ouvert à ses deux extrémités, de section sensiblement hémisphérique, ellipsoïdale ou sphérique.The spacing means may be in the form of one or more ribs. This rib has in the exemplary embodiments shown a cross section of rectangular shape. Such a rib forms with the part from which it projects a niche. However, this rib could have a cross section of different shape such as a square section, triangular, frustoconical or hemispherical. Moreover, when the spacer means comprise a plurality of ribs, the ribs may have different shapes and dimensions. In these different cases, these spacing means 3 form an extra thickness capable of moving at least in the closed position the second part 2 of the first part 1. However, it should be noted that the spacing means could be formed otherwise than by a rib. For example, the second part could have a convex configuration while the first part could be flat or concave, or vice versa. The first and second parts could then define between them an open channel at both ends, of substantially hemispherical, ellipsoidal or spherical section.

Les moyens d'espacement peuvent s'étendre selon une direction longitudinale de la première partie et/ou de ladite seconde partie. Autrement dit, lesdits moyens d'espacement peuvent s'étendre du bord inférieur d'une desdites parties vers le bord supérieur opposé de cette même partie. Dans ce cas, le canal est de préférence rectiligne. Avantageusement, lesdits moyens d'espacement relient le bord inférieur au bord supérieur de sorte qu'ils s'étendent sur toute la longueur de la première et/ou de la seconde partie. Ces moyens d'espacement s'étendent de préférence parallèlement à l'axe de rotation X. Les moyens d'espacement s'étendent alors de préférence parallèlement aux bords longitudinaux extérieur et intérieur.The spacing means may extend in a longitudinal direction of the first portion and / or said second portion. In other words, said spacing means may extend from the lower edge of one of said parts to the opposite upper edge of this same part. In this case, the channel is preferably rectilinear. Advantageously, said means spacers connect the lower edge to the upper edge so that they extend over the entire length of the first and / or second part. These spacing means preferably extend parallel to the axis of rotation X. The spacing means then preferably extend parallel to the outer and inner longitudinal edges.

Il est à noter que les moyens d'espacement pourraient également s'étendre entre un bord supérieur et un bord longitudinal extérieur ou entre un bord inférieur et un bord longitudinal extérieur. Le canal pourrait ainsi tout à fait présenter une configuration coudée. Il est même possible de prévoir des moyens d'espacement s'étendant sensiblement parallèlement aux bords inférieur et supérieur des première et seconde parties. Dans ce cas, lesdits moyens d'espacement peuvent s'étendre perpendiculairement aux bords longitudinaux extérieur 13, 23 et intérieur 14, 24. Lorsque les première et seconde parties sont montées en rotation, les moyens de d'espacement peuvent s'étendre sensiblement perpendiculairement à l'axe de rotation.It should be noted that the spacing means could also extend between an upper edge and an outer longitudinal edge or between a lower edge and an outer longitudinal edge. The channel could well have a bent configuration. It is even possible to provide spacing means extending substantially parallel to the lower and upper edges of the first and second parts. In this case, said spacing means may extend perpendicular to the outer longitudinal edges 13, 23 and inner 14, 24. When the first and second parts are mounted in rotation, the spacing means may extend substantially perpendicularly. to the axis of rotation.

Selon une variante, lesdits moyens d'espacement peuvent s'étendre sur seulement une portion de ladite première et/ou de ladite seconde partie. En particulier, les moyens d'espacement peuvent présenter une dimension strictement inférieure à la dimension des bords longitudinaux des première et/ou seconde parties. Les nervures peuvent donc s'étendre plus ou moins à distance des bords inférieurs et/ou supérieurs des première et/ou seconde parties. Dans ce cas, lesdites nervures pourraient être prévues décalées l'une par rapport à l'autre. Selon un cas particulier, les moyens d'espacement peuvent comprendre une première portion s'étendant sur la première partie et une seconde portion s'étendant sur la seconde partie. En position fermée, la seconde portion peut venir se positionner dans la continuité de la première portion. Les première et seconde portions pourraient alors s'étendre dans un même axe.Alternatively, said spacing means may extend over only a portion of said first and / or second portion. In particular, the spacing means may have a dimension strictly smaller than the dimension of the longitudinal edges of the first and / or second parts. The ribs may therefore extend more or less away from the lower and / or upper edges of the first and / or second parts. In this case, said ribs could be provided offset with respect to each other. In one particular case, the spacing means may comprise a first portion extending on the first portion and a second portion extending on the second portion. In the closed position, the second portion can be positioned in the continuity of the first portion. The first and second portions could then extend in the same axis.

Différents modes de réalisation vont maintenant être décrits en référence aux figures 1 à 6.Various embodiments will now be described with reference to FIGS. 1 to 6.

Selon un premier mode de réalisation représenté sur les figures 1, 2 et 3, lesdits moyens d'espacement comprennent une nervure s'étendant entre le bord inférieur 11 et le bord supérieur 12 de ladite première partie. Dans cet exemple, la nervure s'étend à l'aplomb du bord longitudinal extérieur 13. Cette nervure s'étend parallèlement à ce bord longitudinal extérieur et parallèlement à l'axe de rotation X. En position fermée un canal 4 est donc défini entre ladite nervure et ladite ligne de pliage. Il est à noter que si ladite nervure avait été placée à distance du bord longitudinal extérieur 13, par exemple au milieu de la première partie, un deuxième canal aurait pu être défini entre ladite nervure et ledit bord longitudinal extérieur 13. Pour obtenir un tel deuxième canal, les première et seconde parties peuvent être réalisées en un matériau déformable, et de préférence élastiquement déformable, afin de permettre aux bords longitudinaux extérieurs 13, 23 de venir en contact l'un de l'autre.According to a first embodiment shown in Figures 1, 2 and 3, said spacing means comprise a rib extending between the lower edge 11 and the upper edge 12 of said first portion. In this example, the rib extends perpendicular to the outer longitudinal edge 13. This rib extends parallel to this outer longitudinal edge and parallel to the axis of rotation X. In the closed position, a channel 4 is therefore defined between said rib and said fold line. It should be noted that if said rib had been placed at a distance from the outer longitudinal edge 13, for example in the middle of the first part, a second channel could have been defined between said rib and said external longitudinal edge 13. To obtain such a second channel, the first and second parts may be made of a deformable material, and preferably elastically deformable, to allow the outer longitudinal edges 13, 23 to come into contact with one another.

Le deuxième mode de réalisation représentée sur la figure 4 se distingue du premier mode de réalisation illustré sur les figures 1, 2 et 3 en ce que ledit dispositif comporte une deuxième nervure. Dans cet exemple cette deuxième nervure est de forme et de dimension identique à la première nervure. Cette nervure est prévue sur la première partie de façon adjacente à la ligne de pliage et ainsi de façon adjacente à l'axe de rotation.The second embodiment shown in FIG. 4 differs from the first embodiment illustrated in FIGS. 1, 2 and 3 in that said device comprises a second rib. In this example, this second rib is identical in shape and size to the first rib. This rib is provided on the first portion adjacent to the fold line and thus adjacent to the axis of rotation.

Le troisième mode de réalisation représenté sur la figure 5 se distingue du premier mode de réalisation illustré sur la figure 4 en ce que la deuxième nervure est sur la deuxième partie. Ainsi, le dispositif est dans ce cas pourvu de moyens d'espacement s'étendant à la fois sur la première partie et sur la seconde partie. Cette deuxième nervure est prévue sur la deuxième partie de façon adjacente à la ligne de pliage et ainsi de façon adjacente à l'axe de rotation X. Cette deuxième nervure s'étend parallèlement au bord longitudinal extérieur 23 de la deuxième partie et parallèlement à l'axe de rotation X. En position ouverte, de même qu'en position fermée, cette deuxième nervure s'étend également parallèlement à la première nervure et ainsi parallèlement au bord longitudinal extérieur 13 de la première partie.The third embodiment shown in FIG. 5 differs from the first embodiment illustrated in FIG. 4 in that the second rib is on the second part. Thus, the device is in this case provided with spacing means extending both on the first part and on the second part. This second rib is provided on the second portion adjacent to the fold line and thus adjacent to the axis of rotation X. This second rib extends parallel to the outer longitudinal edge 23 of the second portion and parallel to the X axis of rotation. In the open position, as in the closed position, this second rib also extends parallel to the first rib and thus parallel to the outer longitudinal edge 13 of the first portion.

Pour ces modes de réalisation représentés sur les figures 4 et 5, en position fermée, un canal est délimité par les première et deuxième nervures ensemble avec les première et seconde parties. Le fait de former cette deuxième nervure au niveau de la ligne de pliage annihile tout risque de coincement de cheveux au niveau de cette ligne de pliage. Bien entendu, si la deuxième nervure était prévue à distance de la ligne de pliage, par exemple au milieu de la première partie, un deuxième canal aurait pu être défini entre ladite deuxième nervure et ladite ligne de pliage.For these embodiments shown in Figures 4 and 5, in the closed position, a channel is delimited by the first and second ribs together with the first and second portions. The fact of forming this second rib at the fold line annihilates any risk of jamming of hair at this fold line. Of course, if the second rib was provided at a distance from the fold line, for example in the middle of the first part, a second channel could have been defined between said second rib and said fold line.

Le quatrième mode de réalisation représenté sur la figure 6 se distingue du mode de réalisation représenté sur la figure 4 en ce que ledit dispositif comporte une troisième nervure. Cette troisième nervure est prévue entre lesdites première et seconde nervures et peut s'étendre à équidistance des première ou seconde nervures de façon à former en position fermée du dispositif deux canaux de dimension égale. Dans un tel cas, un premier canal est défini entre la première nervure et la troisième nervure, et un second canal est défini entre la deuxième nervure et la troisième nervure.The fourth embodiment shown in Figure 6 differs from the embodiment shown in Figure 4 in that said device comprises a third rib. This third rib is provided between said first and second ribs and may extend equidistant from the first or second ribs so as to form in the closed position of the device two channels of equal size. In such a case, a first channel is defined between the first rib and the third rib, and a second channel is defined between the second rib and the third rib.

Un exemple de procédé mettant en oeuvre un dispositif selon la présente invention va maintenant être décrit en référence aux figures 7, 8 et 9. Comme visible sur ces figures, ce procédé met en oeuvre le deuxième mode de réalisation de dispositif décrit en référence à la figure 4. Bien entendu, ce procédé s'applique également aux autres modes de réalisation précédemment décrits.An example of a method implementing a device according to the present invention will now be described with reference to FIGS. 7, 8 and 9. As visible in these figures, this method implements the second device embodiment described with reference to FIG. Of course, this method also applies to the other embodiments described above.

Dans une première étape représentée sur la figure 7, l'utilisateur applique un produit de traitement capillaire, et notamment un produit du type colorant ou décolorant, sur le dispositif en position ouverte, de préférence à la fois sur la face interne 10 de la première partie et sur la face interne 20 de la seconde partie. Plus précisément, sur la face interne 10 de la première face 1 ce produit est appliqué entre les moyens d'espacement 3, c'est-à-dire entre les deux nervures. Cette application de produit peut être réalisée à l'aide d'un pinceau 6.In a first step shown in FIG. 7, the user applies a hair treatment product, and in particular a product of the dye or bleaching type, to the device in the open position, preferably both on the internal face 10 of the first part and on the inner face 20 of the second part. More specifically, on the inner face 10 of the first face 1 this product is applied between the spacing means 3, that is to say between the two ribs. This application of product can be carried out using a brush 6.

Dans une seconde étape représentée sur la figure 8, l'utilisateur dispose une ou plusieurs mèche de cheveux 7 sur la face interne 10 de la première partie 1, entre les moyens d'espacement 3. L'utilisateur referme alors le dispositif en rabattant la seconde partie 2 sur la première partie 1.In a second step shown in FIG. 8, the user disposes one or more strands of hair 7 on the internal face 10 of the first part 1, between the spacing means 3. The user then closes the device by folding the second part 2 on the first part 1.

Dans une troisième étape illustrée sur la figure 9, le dispositif est en position fermée avec ladite mèche de cheveux disposée à l'intérieur. Dans cette position, la seconde partie se situe en vis-à-vis de la première partie. Autrement dit, en position fermée, les première et seconde parties s'étendent de part et d'autre de la mèche de cheveux. La mèche de cheveux est ainsi prise en sandwich entre lesdites première et seconde parties. La mèche de cheveux s'étend sur toute la longueur desdites première et seconde parties. Plus précisément, ladite mèche de cheveux s'étend selon un axe d'allongement du canal. En particulier, cette mèche de cheveux s'étend selon une direction générale sensiblement parallèle aux moyens d'espacement. Dans ce mode de réalisation, le canal 4 est délimité par deux moyens d'espacement 3 distants l'un de l'autre. Le canal 4 à l'intérieur duquel s'étend la mèche de cheveux permet alors à cette mèche de ne pas être maintenue nécessairement en contact serrant entre lesdites première et seconde parties en position fermée du dispositif. En effet, l'utilisateur peut varier lui-même l'effort de compression qu'il exerce sur les faces externes 15, 25 du dispositif de façon à plus ou moins imbiber les mèches de cheveux en produit. Selon l'invention, l'utilisateur fait coulisser le dispositif relativement à la mèche de cheveux pour faciliter l'imprégnation en produit de la mèche de cheveux isolée.In a third step illustrated in Figure 9, the device is in closed position with said lock of hair disposed therein. In this position, the second part is vis-à-vis the first part. In other words, in the closed position, the first and second parts extend on either side of the lock of hair. The lock of hair is thus sandwiched between said first and second parts. The lock of hair extends over the entire length of said first and second parts. More specifically, said lock of hair extends along an axis of elongation of the channel. In particular, this lock of hair extends in a general direction substantially parallel to the spacing means. In this embodiment, the channel 4 is delimited by two spacing means 3 spaced apart from each other. The channel 4 within which the lock of hair extends then allows this lock to not necessarily be kept in close contact between said first and second parts in the closed position of the device. Indeed, the user can himself vary the compressive force it exerts on the outer faces 15, 25 of the device so as to more or less imbibe hair locks product. According to the invention, the user slides the device relative to the lock of hair to facilitate product impregnation of the lock of hair isolated.

Tel que précédemment évoqué, les moyens d'espacement évitent tout coincement de la mèche de cheveux au niveau de la ligne de pliage. En outre, ces moyens d'espacement ont pour avantage supplémentaire de calibrer la taille maximale de mèche de cheveux isolée. De plus, la fonction de glissière jouée par les moyens d'espacement est particulièrement intéressante dans ce procédé. En effet, cette glissière guide le positionnement des cheveux lors du coulissement du dispositif et ainsi facilite le maniement du dispositif. Le dispositif peut ainsi être positionné comme bon le souhaite l'utilisateur par rapport à la mèche de cheveux sans que cela n'altère la qualité d'imprégnation de ladite mèche de cheveux en produit.As previously mentioned, the spacing means avoid any jamming of the lock of hair at the fold line. In addition, these spacing means have the additional advantage of calibrating the maximum size of isolated lock of hair. In addition, the slide function played by the spacing means is particularly interesting in this method. Indeed, this slide guides the positioning of the hair during sliding of the device and thus facilitates the handling of the device. The device can thus be positioned as desired by the user by relative to the lock of hair without this altering the quality of impregnation of said lock of hair product.

Un dispositif et un procédé selon l'invention sont particulièrement satisfaisant pour la réalisation de traitement capillaire à domicile, l'utilisateur pouvant se faire soi-même son traitement capillaire avec un résultat professionnel garanti.A device and a method according to the invention are particularly satisfactory for carrying out hair treatment at home, the user being able to do his own hair treatment with a guaranteed professional result.

Dans toute la description, l'expression « comportant un » doit être considérée comme étant synonyme de « comportant au moins un », sauf si le contraire est spécifié. Ainsi, il est à noter qu'un dispositif selon la présente invention, bien qu'étant défini comme comportant une première et une seconde parties, pourrait tout à fait être composé d'un nombre de parties plus important. Par exemple, ledit dispositif pourrait être composé de trois parties, des première et seconde parties articulées entre elles pouvant être rabattues sur une troisième partie avec ladite mèche de cheveux placer entre. Dans ce cas, en position fermée, la troisième partie pourrait latéralement faire saillie relativement à la première partie et pourrait être placé par l'utilisateur sous cette première partie de façon à davantage faciliter la prise en main du dispositif.Throughout the description, the phrase "having one" should be considered synonymous with "having at least one", unless the opposite is specified. Thus, it should be noted that a device according to the present invention, although being defined as having a first and a second portion, could quite be composed of a larger number of parts. For example, said device could be composed of three parts, first and second parts hinged together that can be folded over a third portion with said lock of hair between. In this case, in the closed position, the third part could laterally project relative to the first part and could be placed by the user under this first part so as to facilitate easier handling of the device.

Dans la description détaillée qui précède, il a été fait référence à des 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 foregoing detailed description, reference has been made to preferred embodiments of the invention. It is obvious that variations can be made without departing from the invention as claimed hereinafter.
