Description

La présente invention concerne les dispositifs de traitement de la chevelure, et plus particulièrement mais non exclusivement ceux destinés à la mise en forme de la chevelure, notamment destinés au lissage, au bouclage ou au gaufrage des cheveux, comportant une recharge en produit cosmétique.The present invention relates to devices for treating the hair, and more particularly but not exclusively those for shaping the hair, in particular for smoothing, wrapping or embossing the hair, comprising a refill cosmetic product.

L'invention concerne plus particulièrement les dispositifs comportant deux mâchoires mobiles l'une par rapport à l'autre, pouvant prendre une configuration écartée d'introduction d'une mèche de cheveux entre elles et une configuration rapprochée, de traitement de la mèche, les mâchoires étant déplaçables dans cette configuration rapprochée le long de la mèche. Les mâchoires portent le plus souvent, dans de tels dispositifs, deux éléments chauffants au contact desquels les cheveux sont amenés lors de l'utilisation du dispositif.The invention relates more particularly to devices comprising two jaws movable relative to each other, which can take a configuration of introduction of a lock of hair between them and a close configuration, treatment of the wick, the jaws being movable in this configuration close together along the wick. In such devices, the jaws most often carry two heating elements in contact with which the hair is brought during the use of the device.

Arrière-planBackground

De nombreux dispositifs de ce type, parfois encore appelés fers à lisser, ont déjà été proposés.Many devices of this type, sometimes called straighteners, have already been proposed.

Usuellement, les lisseurs à cheveux consistent en deux bras connectés l'un avec l'autre à l'aide d'une charnière qui permet l'ouverture et la fermeture de ces derniers et en au moins un élément chauffant disposé sur les bras. Lors des opérations de coiffage d'une mèche de cheveux, cette dernière est introduite entre les deux bras en position ouverte, puis les deux bras sont refermés manuellement sur la mèche de cheveux. La mèche de cheveux est alors soumise, jusqu'à l'ouverture des deux bras et l'extraction de la mèche de cheveux, à la chaleur émise par l'élément chauffant.Usually, the hair straighteners consist of two arms connected to each other by means of a hinge which allows the opening and closing of the latter and at least one heating element disposed on the arms. During styling operations of a lock of hair, the latter is introduced between the two arms in the open position, then the two arms are closed manually on the lock of hair. The lock of hair is then subjected, until the opening of the two arms and the extraction of the lock of hair, to the heat emitted by the heating element.

La demande WO 2009/078046 décrit un appareil de coiffage comportant deux bras reliés entre eux pour permettre l'ouverture et la fermeture de l'appareil, au moins un organe chauffant et au moins un siège d'accueil d'un dispositif de traitement capillaire, ce dernier permettant la distribution, en fonctionnement, d'un produit capillaire. Le dispositif de traitement capillaire est composé d'un matériau support imprégné d'un produit capillaire et adapté à une utilisation unique.Requirement WO 2009/078046 discloses a styling apparatus comprising two arms interconnected to allow the opening and closing of the apparatus, at least one heating member and at least one receiving seat of a capillary treatment device, the latter allowing dispensing in operation, a hair product. The hair treatment device is composed of a support material impregnated with a hair product and adapted for a single use.

WO 2009/015027 et US 2009/0025247 divulguent un dispositif de lissage des cheveux, permettant l'application d'un produit capillaire par contact avec les cheveux. Le produit capillaire à appliquer est contenu dans une recharge amovible permettant son application. Celle-ci comporte un réservoir contenant le produit capillaire sous forme gélifiée et des orifices de distribution et d'application du produit, réalisés directement au travers d'une paroi du réservoir. La recharge est introduite dans un logement disposé sur l'un des deux bras du lisseur à cheveux, par coulissement. WO 2009/015027 and US 2009/0025247 disclose a device for smoothing the hair, allowing the application of a hair product by contact with the hair. The hair product to be applied is contained in a removable refill allowing its application. This comprises a reservoir containing the capillary product in gelled form and dispensing and application openings of the product, made directly through a wall of the reservoir. The refill is introduced into a housing disposed on one of the two arms of the hair straightener, by sliding.

Il est connu de la demande WO 2013/045331 un applicateur pour l'application d'une substance de soin aux cheveux, comportant une cartouche de substance de soin reçue dans un logement de l'applicateur. La cartouche comporte un support poreux imbibé de la substance de soin.It is known from the demand WO 2013/045331 an applicator for applying a hair care substance, having a care substance cartridge received in a housing of the applicator. The cartridge has a porous support soaked with the care substance.

La demande WO 2013/090896 concerne un appareil de traitement des cheveux, notamment de coiffage, comportant un support d'agent de traitement, notamment un matériau poreux imbibé, à appliquer sur les cheveux ou la peau. Le support est fixé à un accessoire, lui-même monté de façon amovible sur un appareil de traitement des cheveux. Le support a une forme en T permettant son montage dans une rainure complémentaire de l'accessoire.Requirement WO 2013/090896 relates to a hair treatment apparatus, especially a styling device, comprising a treatment agent support, in particular a porous impregnated material, to be applied to the hair or the skin. The support is attached to an accessory, itself removably mounted on a hair treatment apparatus. The support has a T-shape for mounting in a groove complementary to the accessory.

Il existe un besoin pour perfectionner encore les dispositifs permettant l'application d'un produit capillaire afin de permettre à l'utilisateur de pouvoir aisément recharger le dispositif en produit capillaire et/ou changer de produit capillaire à appliquer.There is a need to further improve the devices for applying a hair product to allow the user to easily reload the device into a hair product and / or change the hair product to be applied.

Résumésummary

L'invention a pour objet, selon un premier de ses aspects, une recharge pour un dispositif de traitement de la chevelure, comportant :

  • un corps présentant une cavité formée par au moins partiellement deux parois opposées et un fond, et s'ouvrant vers l'extérieur par une ouverture, et
  • un organe d'application inséré selon un axe d'insertion X dans la cavité du corps, et s'étendant hors de la cavité par l'ouverture,
The subject of the invention is, according to a first of its aspects, a refill for a device for treating the hair, comprising:
  • a body having a cavity formed by at least partially two opposite walls and a bottom, and opening outwardly through an opening, and
  • an applicator member inserted along an insertion axis X into the body cavity and extending out of the cavity through the opening,

L'un au moins des parois et du fond de la cavité comporte au moins un relief d'accrochage venant en prise sur l'organe d'application pour s'opposer à son extraction de la cavité, ce relief d'accrochage étant conformé pour que la force d'insertion de l'organe d'application dans la cavité soit plus faible que celle d'extraction.At least one of the walls and the bottom of the cavity comprises at least one engaging relief engaging the applicator member to oppose its extraction from the cavity, this hooking relief being shaped to that the insertion force of the applicator member in the cavity is lower than that of extraction.

L'organe d'application peut être inséré facilement dans la cavité et extrait plus difficilement. Cela permet d'avoir un bon maintien de l'organe d'application dans cette dernière.The applicator member can be easily inserted into the cavity and extracted more easily. This makes it possible to have a good maintenance of the application member in the latter.

L'insertion et l'extraction de l'organe d'application sont ici réalisées selon la même direction, mais dans des sens opposés.The insertion and extraction of the application member are here performed in the same direction, but in opposite directions.

Le relief d'accrochage peut être conformé pour endommager l'organe d'application lors de l'extraction de ce dernier. Ainsi, l'organe d'application n'est pas réutilisable, ce qui permet de limiter les risques sanitaires liés à sa réutilisation.The hooking relief can be shaped to damage the application member during the extraction of the latter. Thus, the application member is not reusable, which limits the health risks associated with its reuse.

Le relief d'accrochage peut être conformé pour se séparer, notamment par l'intermédiaire d'une cassure, de la paroi ou du fond qui le porte lors de l'extraction de l'organe d'application de la cavité, de sorte que la recharge n'est pas réutilisable.The hooking relief may be shaped to separate, in particular by means of a break, from the wall or the bottom which bears it during the extraction of the cavity application member, so that the refill is not reusable.

La différence ΔF entre la force d'insertion et la force d'extraction de l'organe d'application de la cavité peut être supérieure ou égale à 3 N, de préférence supérieure ou égale à 4 N.The difference Δ F between the insertion force and the extraction force of the cavity application member may be greater than or equal to 3 N, preferably greater than or equal to 4 N.

De préférence, l'organe d'application est en un matériau poreux, notamment en fibres synthétiques ou naturelles orientées toutes sensiblement dans la même direction et assemblées pour former un feutre. L'organe d'application peut présenter une densité de fibres comprise entre 0,080 g/cm3 et 0,400 g/cm3. Un tel matériau permet notamment de conditionner et d'appliquer le produit cosmétique.Preferably, the applicator member is made of a porous material, in particular synthetic or natural fibers all oriented substantially in the same direction and assembled to form a felt. The applicator member may have a fiber density of between 0.080 g / cm 3 and 0.400 g / cm 3 . Such a material makes it possible in particular to condition and apply the cosmetic product.

En variante, l'organe d'application comporte au moins deux parties ayant des densités de fibres et/ou des orientations de fibres différentes. Par exemple, l'une des deux parties peut former un réservoir de produit et l'autre permettre l'application du produit cosmétique.Alternatively, the applicator member comprises at least two portions having different fiber densities and / or fiber orientations. For example, one of the two parts may form a product reservoir and the other allow the application of the cosmetic product.

L'organe d'application est, de préférence, imprégné de produit cosmétique.The applicator member is preferably impregnated with a cosmetic product.

De préférence, l'organe d'application est compressible. Lors de l'insertion de l'organe d'application dans la cavité, ce dernier peut se déformer localement au contact du relief d'accrochage et épouser sensiblement la forme de la cavité. Lors de l'extraction de l'organe d'application de la cavité, le relief d'accrochage peut retenir l'organe d'application dans cette dernière en venant notamment en prise avec ce dernier, notamment avec les fibres de l'organe d'application.Preferably, the applicator member is compressible. During insertion of the applicator member into the cavity, the latter may locally deform in contact with the hooking relief and substantially conform to the shape of the cavity. During the extraction of the application member of the cavity, the hooking relief can retain the applicator member in the latter especially in engagement with the latter, in particular with the fibers of the body of the body. 'application.

L'organe d'application peut comporter des zones de prédécoupes destinées à se déchirer lors de l'extraction de la cavité de ce dernier, rendant l'organe d'application non réutilisable.The applicator member may include pre-cut areas intended to tear during the extraction of the cavity of the latter, making the applicator member non-reusable.

De préférence, le relief d'accrochage s'étend de ladite paroi ou dudit fond dans une direction sensiblement perpendiculaire à celle des fibres de l'organe d'application. Dans cette configuration, le relief d'accrochage, en venant en prise avec les fibres de l'organe d'application perpendiculairement à ces dernières, peut arracher les fibres, ce qui endommage l'organe d'application et empêche sa réutilisation.Preferably, the attachment relief extends from said wall or said bottom in a direction substantially perpendicular to that of the fibers of the applicator member. In this configuration, the hooking relief, engaging the fibers of the applicator member perpendicularly to the latter, can tear the fibers, which damages the applicator member and prevents reuse.

De préférence, la cavité présente une hauteur H, définie à partir de l'ouverture selon l'axe d'insertion X, le relief d'accrochage s'étendant selon l'axe d'insertion X sur une longueur l inférieure à cette hauteur H. Preferably, the cavity has a height H , defined from the opening along the insertion axis X, the attachment relief extending along the insertion axis X over a length l less than this height. H.

De préférence, le relief d'accrochage est asymétrique par rapport à un plan transversal médian pour celui-ci. Une telle asymétrie permet notamment d'avoir des propriétés d'insertion de l'organe d'application différente de ses propriétés d'extraction.Preferably, the hooking relief is asymmetrical with respect to a median transverse plane for it. Such asymmetry makes it possible, in particular, to have insertion properties of the application member that differs from its extraction properties.

De préférence, le relief d'accrochage présente une épaisseur e, mesurée dans un plan perpendiculaire à ladite paroi ou audit fond, variable selon l'axe d'insertion X. L'épaisseur e est, de préférence :

  • croissante sur toute la longueur l du relief d'accrochage selon l'axe d'insertion X de l'organe d'application, ou
  • croissante sur une première portion de longueur l1 selon l'axe d'insertion X puis décroissante sur une deuxième portion de longueur l2 selon l'axe d'insertion X, le rapport des longueurs l2 /l1 étant inférieur à 1, de préférence inférieur ou égal à 0,5, encore mieux inférieur ou égal à 0,2, ou
  • croissante sur une première portion de longueur l1 selon l'axe d'insertion X puis constante sur une deuxième portion de longueur l3* selon l'axe d'insertion X, l'épaisseur de la deuxième portion étant inférieure à l'épaisseur maximale emax de la première portion.
Preferably, the hooking relief has a thickness e , measured in a plane perpendicular to said wall or said bottom, variable along the axis of insertion X. The thickness e is, preferably:
  • increasing throughout the length l of the hooking relief along the insertion axis X of the application member, or
  • increasing on a first portion of length l 1 along the insertion axis X and then decreasing on a second portion of length l 2 along the axis of insertion X, the ratio of the lengths l 2 / l 1 being less than 1, preferably less than or equal to 0.5, more preferably less than or equal to 0.2, or
  • increasing on a first portion of length l 1 along the insertion axis X and then constant on a second portion of length l 3 * along the axis of insertion X, the thickness of the second portion being less than the thickness maximum e max of the first portion.

Cela permet d'avoir un relief d'accrochage ayant une pente plus faible dans le sens de l'insertion de l'organe d'application que celle dans le sens de l'extraction. Cela permet notamment de rendre l'extraction de l'organe d'application plus difficile.This makes it possible to have an attachment relief having a lower slope in the direction of insertion of the applicator member than that in the direction of extraction. This allows in particular to make the extraction of the application member more difficult.

Lorsque le relief d'accrochage est sur l'une des parois opposées, les parois opposées peuvent, sur une hauteur h non nulle à partir du fond de la cavité, être dépourvues de relief d'accrochage. De ce fait, l'organe d'application s'étend, une fois introduit dans la cavité, au moins en partie sous le relief d'accrochage dans la cavité. Cela permet notamment au relief d'accrochage une meilleure prise sur l'organe d'application, notamment ses fibres, dans le sens de son extraction.When the attachment relief is on one of the opposite walls, the opposite walls may, at a height h non-zero from the bottom of the cavity, be devoid of relief hooking. Therefore, the applicator member extends, once introduced into the cavity, at least partially under the hooking relief in the cavity. This allows the snagging relief a better grip on the application member, including its fibers, in the direction of its extraction.

De préférence, le ou chaque relief d'accrochage présente :

  • une première face orientée vers l'ouverture ayant une pente moyenne formant un angle α inférieur ou égal à 45° avec l'axe d'insertion X, et
  • une deuxième face orientée vers le côté opposé à l'ouverture ayant une pente moyenne formant un angle β supérieur ou égal à 45° avec l'axe d'introduction X, mieux supérieur ou égal à 80°, encore mieux supérieur ou égal à 90°.
Preferably, the or each attachment relief has:
  • a first face oriented towards the aperture having a mean slope forming an angle α less than or equal to 45 ° with the insertion axis X, and
  • a second face facing the opposite side to the opening having a mean slope forming an angle β greater than or equal to 45 ° with the insertion axis X, better than or equal to 80 °, more preferably greater than or equal to 90 °.

La première face et la deuxième face peuvent former, à leur jonction, un angle γ inférieur ou égal à 110°, mieux inférieur ou égal à 90° et/ou supérieur à 45°.The first face and the second face may form, at their junction, an angle γ less than or equal to 110 °, better than or equal to 90 ° and / or greater than 45 °.

Le relief d'accrochage peut présenter au moins une arête, notamment une arête longitudinale et/ou une arête transversale à la jonction entre la première et la deuxième face.The hooking relief may have at least one edge, in particular a longitudinal edge and / or a transverse edge at the junction between the first and second faces.

Le relief d'accrochage peut être, en coupe longitudinale, de forme sensiblement triangulaire, notamment lorsque ce dernier est sur l'une des parois opposées, ou en forme de flèche, la pointe étant orientée vers l'ouverture de la cavité, notamment lorsque le relief d'accrochage est sur le fond.The hooking relief may be, in longitudinal section, of substantially triangular shape, especially when the latter is on one of the opposite walls, or in the form of an arrow, the tip being oriented towards the opening of the cavity, particularly when the hanging relief is on the bottom.

Lorsque le relief d'accrochage est sur l'une des parois opposées, le relief d'accrochage peut être, en coupe transversale, de forme semi-circulaire ou non, notamment polygonale, en particulier rectangulaire, carrée ou triangulaire. Lorsque le relief d'accrochage est sur le fond, le relief d'accrochage peut être, en coupe transversale, de forme circulaire ou non, notamment polygonale.When the hooking relief is on one of the opposite walls, the hooking relief may be, in cross section, of semicircular shape or not, in particular polygonal, in particular rectangular, square or triangular. When the hooking relief is on the bottom, the attachment relief may be, in cross section, of circular shape or not, including polygonal.

L'épaisseur maximale emax du relief d'accrochage, mesurée dans un plan perpendiculaire à ladite paroi ou audit fond sur laquelle il se raccorde, peut être comprise entre 0,2 mm et 3 mm, mieux entre 0,5 mm et 2 mm.The maximum thickness e max of the attachment relief, measured in a plane perpendicular to said wall or to said base on which it is connected, may be between 0.2 mm and 3 mm, better still between 0.5 mm and 2 mm. .

Le relief d'accrochage peut s'étendre selon l'axe d'insertion X sur une longueur l comprise entre 1 mm et 30 mm, mieux entre 5 mm et 15 mm.The hooking relief may extend along the axis of insertion X over a length l of between 1 mm and 30 mm, better still between 5 mm and 15 mm.

Le relief d'accrochage peut avoir une largeur maximale k, prise parallèlement à ladite paroi, comprise entre 0,2 mm et 5 mm, mieux entre 0,5 mm et 2 mm.The hooking relief may have a maximum width k , taken parallel to said wall, between 0.2 mm and 5 mm, better between 0.5 mm and 2 mm.

De préférence, le relief d'accrochage est moulé avec le corps.Preferably, the attachment relief is molded with the body.

En variante, le relief d'accrochage est rapporté dans la cavité. Le relief d'accrochage peut être en un matériau différent du corps.Alternatively, the attachment relief is reported in the cavity. The attachment relief may be in a different material of the body.

Le relief d'accrochage peut comporter une zone amincie, notamment une zone de largeur plus faible, configurée pour se casser si l'utilisateur retire l'organe d'application de la cavité.The attachment relief may comprise a thinned zone, in particular a zone of smaller width, configured to break if the user removes the applicator member from the cavity.

Au moins l'une des parois ou le fond peut comporter une pluralité de reliefs d'accrochage. Au moins une paroi ou le fond peut comporter moins de 10 reliefs d'accrochage, mieux entre 3 et 8 reliefs d'accrochage.At least one of the walls or the bottom may comprise a plurality of attachment reliefs. At least one wall or the bottom may have fewer than 10 attachment reliefs, better between 3 and 8 hooking reliefs.

Tous les reliefs d'accrochage peuvent être identiques. En variante, au moins l'un des reliefs d'accrochage est différent des autres.All the hooking reliefs may be identical. In a variant, at least one of the attachment reliefs is different from the others.

Une des deux parois opposées et/ou le fond peut être dépourvue de relief d'accrochage ou les deux parois opposées et/ou le fond peuvent présenter chacune au moins un relief d'accrochage.One of the two opposite walls and / or the bottom may be devoid of hooking relief or the two opposite walls and / or the bottom may each have at least one attachment relief.

Les reliefs d'accrochage de l'une des parois opposées peuvent être situés en vis-à-vis des reliefs d'accrochage de l'autre des parois opposées. En variante, les reliefs d'accrochage de l'une des parois opposées alternent avec les reliefs d'accrochage de l'autre des parois opposées.The hooking reliefs of one of the opposite walls may be located vis-à-vis the hooking reliefs on the other opposite walls. In a variant, the hooking reliefs of one of the opposite walls alternate with the hooking reliefs of the other of the opposite walls.

Une des deux parois opposées peut comporter au moins un relief de compression en saillie. L'autre des deux parois opposées comporte, de préférence, des reliefs d'accrochage, le relief de compression venant appuyer l'organe d'application contre les reliefs d'accrochage de l'autre des parois latérales.One of the two opposite walls may comprise at least one projecting compression relief. The other of the two opposite walls preferably comprises hooking reliefs, the compression relief coming to support the applicator member against the hooking reliefs of the other of the side walls.

De préférence, les parois opposées sont planes et parallèles l'une à l'autre. Le fond peut être plan.Preferably, the opposite walls are flat and parallel to each other. The bottom can be plane.

De préférence, la cavité est de forme allongée dans une direction perpendiculaire à l'axe d'insertion.Preferably, the cavity is elongate in a direction perpendicular to the insertion axis.

L'invention a encore pour objet un dispositif de traitement de la chevelure, comportant :

  • deux bras mobiles l'un relativement à l'autre entre une configuration rapprochée de traitement de la chevelure et une configuration écartée d'engagement entre eux de cheveux à traiter, l'un des bras comportant un logement,
  • une recharge selon l'invention, telle que définie précédemment, disposée de façon amovible dans le logement.
The invention further relates to a device for treating the hair, comprising:
  • two movable arms relative to each other between a close configuration of treatment of the hair and a configuration apart from engagement between them of hair to be treated, one of the arms comprising a housing,
  • a refill according to the invention, as defined above, removably disposed in the housing.

L'utilisation d'une recharge permet à l'utilisateur de pouvoir appliquer aisément différents produits capillaires par simple changement de la recharge.The use of a refill allows the user to easily apply different hair products by simply changing the refill.

Cela permet également à l'utilisateur de pouvoir changer la recharge lorsque celle-ci ne contient plus ou plus suffisamment de produit cosmétique.This also allows the user to be able to change the refill when it no longer contains enough cosmetics or more.

Le bras opposé à celui sur lequel la recharge est disposée peut présenter une sortie de vapeur, et de préférence également un peigne.The opposite arm to that on which the refill is disposed may have a steam outlet, and preferably also a comb.

De préférence, notamment lorsque l'on cherche à lisser les cheveux, le dispositif comporte un élément chauffant destiné à venir au contact des cheveux, et mieux deux éléments chauffants disposés chacun sur un bras. Ce ou ces éléments chauffants peuvent comporter chacun une plaque en un matériau bon conducteur de la chaleur, définissant une surface chaude de contact avec les cheveux, dont la température est par exemple supérieure ou égale à 95°C, mieux comprise entre 90 et 230°C.Preferably, especially when one seeks to smooth the hair, the device comprises a heating element intended to come into contact with the hair, and better two heating elements each arranged on an arm.

Dans la suite de la description, les éléments identiques ou de fonctions identiques portent le même signe de référence. À fin de concision de la présente description, ils ne sont pas décrits en regard de chacune des figures, seules les différences entre les modes de réalisations étant décrites.In the remainder of the description, identical elements or identical functions bear the same reference sign. For the sake of brevity of the present description, they are not described with respect to each of the figures, only the differences between the embodiments being described.

On a représenté aux figures 1 et 2 la pièce à main 2 d'un exemple de dispositif de traitement de la chevelure selon l'invention.Representatives figures 1 and 2 the handpiece 2 of an example of a device for treating the hair of the invention.

Cette pièce à main 2 présente deux mâchoires 3 et 4 mobiles l'une par rapport à l'autre entre une configuration écartée (non représentée) d'introduction entre elles d'une mèche de cheveux et une configuration rapprochée de traitement.This handpiece 2 has two jaws 3 and 4 movable relative to each other between a spaced configuration (not shown) of introduction between them of a lock of hair and a close configuration of treatment.

Les mâchoires 3 et 4 sont portées par des bras respectifs supérieur 5 et inférieur 6, lesquels sont, dans l'exemple considéré, reliés entre eux à une extrémité par une articulation 8, la pièce à main 2 formant ainsi une pince.The jaws 3 and 4 are carried by respective upper and lower arms 6, which are, in this example, interconnected at one end by a hinge 8, the handpiece 2 thus forming a clamp.

Les bras supérieur 5 et inférieur 6 ont chacun, de préférence, une longueur totale comprise entre 22 cm et 37 cm, de préférence 31 cm, et définissent, entre l'articulation 8 et les mâchoires 3 et 4, des demi-poignées respectives 10 et 11 sur lesquelles l'utilisateur peut appuyer pour rapprocher les mâchoires 3 et 4.The upper and lower arms 6 each preferably have a total length of between 22 cm and 37 cm, preferably 31 cm, and define, between the hinge 8 and the jaws 3 and 4, respective half-handles 10 and 11 on which the user can press to bring the jaws 3 and 4 closer together.

Un organe de rappel élastique (non apparent) est de préférence prévu pour rappeler les mâchoires 3 et 4 en configuration écartée, cet organe de rappel élastique étant par exemple un ressort disposé autour d'un axe de l'articulation 8.An elastic return member (not apparent) is preferably provided to return the jaws 3 and 4 in the spaced configuration, this elastic return member being for example a spring disposed about an axis of the hinge 8.

L'invention n'est pas limitée à une façon particulière de relier les bras supérieur 5 et inférieur 6 entre eux et les mâchoires 3 et 4 peuvent être rendues mobiles autrement sans que l'on ne sorte du cadre de la présente invention. Toutefois, la présence d'une articulation est largement préférée pour l'ergonomie qu'elle apporte.The invention is not limited to a particular way of connecting the upper and lower arms 6 to each other and the jaws 3 and 4 can be made mobile otherwise without departing from the scope of the present invention. However, the presence of a joint is widely preferred for the ergonomics it brings.

Les mâchoires 3 et 4 définissent entre elles une zone de traitement de la chevelure, destinée à recevoir une mèche de cheveux à traiter, le long de laquelle la pièce à main 2 est déplacée durant le traitement, par exemple dans le sens allant de la racine vers la pointe des cheveux.The jaws 3 and 4 define between them a hair treatment zone intended to receive a strand of hair to be treated, along which the handpiece 2 is moved during the treatment, for example in the direction from the root towards the tip of the hair.

Dans l'exemple considéré, la pièce à main 2 est configurée pour appliquer un produit cosmétique, assurer un traitement de la chevelure par de la vapeur, puis effectuer un traitement thermique des cheveux par contact avec deux surfaces chaudes 15 et 16.In the example considered, the handpiece 2 is configured to apply a cosmetic product, provide treatment of the hair with steam, and then heat treatment of the hair by contact with two hot surfaces 15 and 16.

La direction D de déplacement de la pièce à main 2 sur les cheveux, illustrée sur la figure 4, est de préférence sensiblement perpendiculaire aux bras supérieur 5 et inférieur 6.The direction D of movement of the handpiece 2 on the hair, illustrated on the figure 4 , is preferably substantially perpendicular to the upper arm 5 and lower 6.

La pièce à main 2 est reliée par un cordon, dans l'exemple considéré, à une station de base non représentée, fixe durant le traitement, reliée au secteur.The handpiece 2 is connected by a cord, in the example considered, to a base station not shown, fixed during the treatment, connected to the sector.

Cette station de base assure l'alimentation électrique de la pièce à main 2 ainsi que son alimentation en eau en vue de la génération de vapeur et peut réaliser aussi des fonctions annexes de traitement de signaux électriques reçus de la pièce à main 2. Le cordon 18 qui relie la pièce à main 2 à la station de base peut ainsi comporter divers conducteurs électriques et un tuyau d'alimentation en eau.This base station provides power to the handpiece 2 and its water supply for steam generation and can also perform ancillary functions for processing electrical signals received from the handpiece 2. The cord 18 which connects the handpiece 2 to the base station can thus include various electrical conductors and a water supply pipe.

Une interface utilisateur, non représentée sur les figures, peut être présente sur la pièce à main 2 pour permettre à l'utilisateur par exemple de mettre en marche ou non certains composants de celle-ci.A user interface, not shown in the figures, may be present on the handpiece 2 to allow the user for example to start or not certain components thereof.

L'application du produit cosmétique est assurée par une recharge 20 portée par l'un des deux bras, 5 ou 6, ici, le bras supérieur 5 qui vient au contact d'un élément presseur 21. Ce dernier peut être amovible.The application of the cosmetic product is ensured by a refill 20 carried by one of the two arms, 5 or 6, here, the upper arm 5 which comes into contact with a pressing element 21. The latter can be removable.

La recharge 20 comporte un corps 23 et un organe d'application 26 disposé de façon à venir au contact des cheveux s'étendant à travers la zone de traitement.The refill 20 comprises a body 23 and an applicator member 26 arranged to come into contact with the hair extending through the treatment zone.

La recharge 20 peut être fixée sur le bras 5 ou 6 par tout moyen, notamment, comme illustré sur la figure 2, pas coulissement d'une nervure du corps 23 dans une rainure de forme complémentaire.The refill 20 can be fixed on the arm 5 or 6 by any means, in particular, as illustrated in FIG. figure 2 , not sliding a rib of the body 23 in a groove of complementary shape.

Le corps 23 présente une cavité 30 s'ouvrant vers l'extérieur par une ouverture 31 dans laquelle s'insère, selon un axe X d'insertion et d'extraction (ci-après axe d'insertion X), l'organe d'application 26 lors de la fabrication de la recharge. Le corps 23 comporte des reliefs d'accrochage 32 s'étendant dans la cavité 30.The body 23 has a cavity 30 opening outwards through an opening 31 into which, along an insertion and extraction axis X (hereinafter insertion axis X), the body application 26 during the manufacture of the refill. The body 23 has hooking reliefs 32 extending into the cavity 30.

Le corps 23 est illustré plus en détail sur les figures 3 à 6.The body 23 is illustrated in more detail on the Figures 3 to 6 .

Le corps 23 présente sensiblement la forme générale d'un parallélépipède rectangle et est allongé selon un axe longitudinal Z. En section transversale, le corps 23 présente, comme illustré sur la figure 5, une forme en U.The body 23 has substantially the general shape of a rectangular parallelepiped and is elongate along a longitudinal axis Z. In cross section, the body 23 has, as illustrated in FIG. figure 5 , a U shape.

Le corps 23 comporte une paroi avant 38 et une paroi arrière 40 opposées, reliées par deux parois latérales 34 et 36 et par un fond 42.The body 23 has a front wall 38 and a rear wall 40 opposite, connected by two side walls 34 and 36 and a bottom 42.

Les reliefs d'accrochage 32 sont chacun asymétriques par rapport à leur axe médian M.The hooking reliefs 32 are each asymmetrical with respect to their median axis M.

Les reliefs d'accrochage 32 s'étendent à partir des deux parois latérales opposées 34 et 36 du corps 30 et sont tous identiques. Chaque paroi latérale 34 ou 36 comporte cinq reliefs d'accrochage mais il peut en être autrement. Les reliefs d'accrochage 32 de l'une des deux parois 34 et 36 sont disposés en vis-à-vis des reliefs d'accrochage 32 de l'autre de ces parois.The hooking reliefs 32 extend from the two opposite side walls 34 and 36 of the body 30 and are all identical. Each side wall 34 or 36 has five hooking reliefs but it may be otherwise. The attachment reliefs 32 of one of the two walls 34 and 36 are arranged vis-à-vis the attachment reliefs 32 of the other of these walls.

Les reliefs d'accrochage 32 sont allongés selon l'axe d'insertion X et présentent, en section longitudinale comme illustré sur la figure 5, une forme sensiblement triangulaire. En section transversale comme illustré sur la figure 6, ces derniers présentent une forme sensiblement en rectangle, leur largeur maximale k étant plus petite que leur épaisseur maximale emax. The hooking reliefs 32 are elongate along the insertion axis X and have, in longitudinal section as illustrated in FIG. figure 5 , a substantially triangular shape. In cross section as illustrated on the figure 6 these latter have a substantially rectangular shape, their maximum width k being smaller than their maximum thickness e max .

Chaque relief d'accrochage 32 comporte une première face plane 46 orientée vers l'ouverture 31 et parallèle à l'axe longitudinal Z de la cavité 30 et une deuxième face plane 48 orientée vers le fond 42.Each attachment relief 32 has a first flat face 46 facing the opening 31 and parallel to the longitudinal axis Z of the cavity 30 and a second flat face 48 facing towards the bottom 42.

La première face 46 forme un angle α avec l'axe d'insertion X, sensiblement égal à 10°, et s'étend sur toute la longueur l du relief d'accrochage 32. La deuxième face 48 est sensiblement perpendiculaire à l'axe d'insertion X. La première face 46 et la deuxième face 48 présentent une arête commune 49. La première et la deuxième face 46 et 48 forment entre elle un angle γ égal à β-α, soit ici sensiblement égal à 80°. Le relief d'accrochage 32 peut ainsi présenter comme illustré une épaisseur e croissante sur toute sa longueur l.The first face 46 forms an angle α with the insertion axis X, substantially equal to 10 °, and extends over the entire length l of the hooking relief 32. The second face 48 is substantially perpendicular to the axis insertion X. the first face 46 and second face 48 have a common edge 49. the first and the second face 46 and 48 form between them an angle γ equal to β-α, is here substantially equal to 80 °. The hooking relief 32 can thus have, as illustrated, an increasing thickness e along its entire length 1 .

La première face plane 46 est reliée à la paroi à partir de laquelle elle s'étend 34 ou 36 par deux faces planes 50 et 52 formant les côtés du relief d'accrochage 32. Les faces 50 et 52 forment avec l'axe longitudinal X un angle égal à l'angle α que forme la première face 46.The first flat face 46 is connected to the wall from which it extends 34 or 36 by two flat faces 50 and 52 forming the sides of the hooking relief 32. The faces 50 and 52 form with the longitudinal axis X an angle equal to the angle α that forms the first face 46.

Les reliefs d'accrochage 32 sont moulés avec le corps 23.The attachment reliefs 32 are molded with the body 23.

Le corps 23 et les reliefs d'accrochage 32 sont en matière thermoplastique, notamment en polytéréphtalate de butylène (PBT), en polytéréphtalate d'éthylène (PET), en polyamide (PA), en polypropylène, en copolyester, notamment en Tritan®, en élastomère ou en leur mélange, en particulier en un mélange de PBT et PET..The body 23 and the attachment reliefs 32 are made of thermoplastic material, in particular polybutylene terephthalate (PBT), polyethylene terephthalate (PET), polyamide (PA), polypropylene, copolyester, especially Tritan®, in elastomer or in their mixture, in particular in a mixture of PBT and PET.

Les reliefs d'accrochage 32 s'étendent sur une longueur l de l'ouverture 31 vers le fond 42, égale ici à environ 10 mm. L'épaisseur maximale emax des reliefs d'accrochage 32 à partir de la paroi 34 ou 36 est ici égale à environ 1,5 mm. La largeur maximale k des reliefs d'accrochage 32, prise parallèlement à la paroi 36 est ici égale à environ 1 mm.The attachment reliefs 32 extend over a length l of the opening 31 to the bottom 42, here equal to about 10 mm. The maximum thickness e max of the hooking reliefs 32 from the wall 34 or 36 is here equal to about 1.5 mm. The maximum width k of the attachment reliefs 32, taken parallel to the wall 36 is here equal to about 1 mm.

La cavité 30 présente une largeur K égale à environ 8 mm, une longueur L égale à environ 90 mm et une hauteur H égale à environ 15 mm.The cavity 30 has a width K equal to about 8 mm, a length L equal to about 90 mm and a height H equal to about 15 mm.

Les parois latérales 34 et 36 ne présentent pas de reliefs d'accrochage 32 sur une hauteur h à partir du fond égale à H-l, soit ici environ 5 mm.The side walls 34 and 36 do not have attachment reliefs 32 over a height h from the bottom equal to H1 , ie here about 5 mm.

En variante, la première et la deuxième faces 46 et 48 se raccordent par une portion arrondie 49.Alternatively, the first and second faces 46 and 48 are connected by a rounded portion 49.

L'organe d'application 26 est de forme sensiblement parallélépipédique rectangle, notamment de dimensions égales à celles de la cavité 30.The applicator member 26 is of substantially rectangular parallelepipedal shape, in particular of dimensions equal to those of the cavity 30.

Une telle recharge 20 est particulièrement adaptée lorsque l'organe d'application 26 est un feutre :

  • de forme complémentaire de celle de la cavité 30,
  • formé de fibre orientées toutes sensiblement selon l'axe longitudinal Z de la cavité 30 et
  • présentant une densité de fibres comprise entre 0,080 g/cm3et 0,400g/cm3.
Such a refill 20 is particularly suitable when the applicator member 26 is a felt:
  • of complementary shape to that of the cavity 30,
  • formed of fiber all oriented substantially along the longitudinal axis Z of the cavity 30 and
  • having a fiber density of between 0.080 g / cm 3 and 0.400 g / cm 3 .

L'exemple des figures 7 à 10 diffère de celui des figures 3 à 6 par la forme des reliefs d'accrochage 32. En coupe transversale comme illustré sur la figure 10, les reliefs d'accrochage 32 ont une forme de triangle rectangle. Chaque relief d'accrochage 32 présente deux premières faces planes 46a et 46b s'étendant longitudinalement sur toute la longueur l du relief d'accrochage 32 et une deuxième face 48. Cette dernière est identique à celle décrite précédemment. Les deux premières faces 46a et 46b s'étendent de la paroi 36 à une arête longitudinale commune 60. Elles forment entre elles un angle λ sensiblement égal à 45°. L'arête 64 et les deux premières faces 46a et 46b forment un angle α avec l'axe d'insertion X sensiblement égal à 5°. L'angle γ entre les premières 46a et 46b et la deuxième face 48 est sensiblement égal à 85°. La première face 60 est perpendiculaire à la paroi 36.The example of Figures 7 to 10 differs from that of Figures 3 to 6 by the shape of the attachment reliefs 32. In cross-section as illustrated on the figure 10 , the hooking reliefs 32 have a shape of a right triangle. Each hooking projection 32 has two first flat faces 46a and 46b extending longitudinally along the entire length l of the hooking relief 32 and a second face 48. The latter is identical to that described above. The first two faces 46a and 46b extend from the wall 36 to a common longitudinal edge 60. They form between them an angle λ substantially equal to 45 °. The edge 64 and the first two faces 46a and 46b form an angle α with the insertion axis X substantially equal to 5 °. The angle γ between the first 46a and 46b and the second face 48 is substantially equal to 85 °. The first face 60 is perpendicular to the wall 36.

L'épaisseur maximale emax et la largeur maximale k des reliefs d'accrochage 32 sont ici sensiblement égales à 0,8 mm.The maximum thickness e max and the maximum width k of the hooking reliefs 32 are here substantially equal to 0.8 mm.

Une telle recharge 20 est particulièrement adaptée lorsque l'organe d'application 26 est un feutre :

  • de forme complémentaire de celle de la cavité 30,
  • formé de fibre orientées toutes sensiblement selon l'axe longitudinal Z de la cavité 30 et
  • présentant une densité de fibres comprise entre 0,080 g/cm3 et 0,400 g/cm3.
Such a refill 20 is particularly suitable when the applicator member 26 is a felt:
  • of complementary shape to that of the cavity 30,
  • formed of fiber all oriented substantially along the longitudinal axis Z of the cavity 30 and
  • having a fiber density of between 0.080 g / cm 3 and 0.400 g / cm 3 .

Les exemples des figures 11A à 11M diffèrent de ceux des figures précédentes par la forme, en section longitudinale, et/ou la position des reliefs d'accrochage 32.Examples of Figures 11A to 11M differ from those of the preceding figures by the shape, in longitudinal section, and / or the position of the attachment reliefs 32.

L'exemple de la figure 11A présente des reliefs d'accrochage 32 en forme de demi-sapin en section longitudinale. Chaque relief d'accrochage 32 présente une pluralité d'arêtes 49 orientées vers le fond 42 du corps 23.The example of figure 11A has hooking reliefs 32 in the form of half-fir in longitudinal section. Each attachment relief 32 has a plurality of ridges 49 oriented towards the bottom 42 of the body 23.

L'exemple de la figure 11B comporte des reliefs d'accrochage 32 rapportés sur les parois 34 et 36 du corps 23 et s'étendant sur toute la hauteur H de la cavité 30.The example of Figure 11B has hooking reliefs 32 attached to the walls 34 and 36 of the body 23 and extending over the entire height H of the cavity 30.

L'exemple de la figure 11C présente des reliefs d'accrochage 32 présentant chacun une arête 49 orientée vers le fond 42. La deuxième face 48 forme un angle β supérieur à 90°, mieux supérieur ou égal à 135°. Les reliefs d'accrochage 32 se déforment élastiquement. Lors de l'insertion de l'organe d'application 26, les reliefs d'accrochage 32 se déforment en se courbant davantage vers le fond de la cavité 30, de sorte que l'angle β augmente et la distance de l'arête à la paroi 34 ou 36 diminue. Lors de l'extraction de l'organe d'application 26, les reliefs d'accrochage 32 peuvent se déformer vers l'ouverture 31 de sorte que l'angle β diminue, la distance de la pointe 70 à la paroi 34ou 36 augmente et, en se déformant, comprime davantage l'organe d'application 26, rendant son extraction plus difficile.The example of figure 11C has hooking reliefs 32 each having an edge 49 oriented towards the bottom 42. The second face 48 forms an angle β greater than 90 °, better than or equal to 135 °. The attachment reliefs 32 deform elastically. During the insertion of the applicator member 26, the attachment reliefs 32 deform by curving more towards the bottom of the cavity 30, so that the angle β increases and the distance from the edge to the wall 34 or 36 decreases. During the extraction of the application member 26, the attachment reliefs 32 may deform towards the opening 31 so that the angle β decreases, the distance from the tip 70 to the wall 34 or 36 increases and , deforming, further compresses the applicator member 26, making its extraction more difficult.

En variante, les reliefs d'accrochage 32 tels que décrits précédemment ne sont pas déformables. Les reliefs d'accrochage 32 peuvent à l'extraction de l'organe d'application 26 se crocheter dans ce dernier pour empêcher son extraction.As a variant, the hooking reliefs 32 as described above are not deformable. The hooking reliefs 32 can extract the applicator member 26 to hook in the latter to prevent its extraction.

L'exemple de la figure 11D comporte des reliefs d'accrochage 32 rapportés sur les parois 34 et 36 du corps 23. Les reliefs d'accrochage 32 sont formés par découpage et pliage de plaques 72 et 74 s'ajustant sur les parois latérales 34 et 36 du corps 23. Les reliefs d'accrochage sont formés de portions des plaques 72 et 74 pliées vers l'intérieur de la cavité. Les reliefs d'accrochage 32 sont orientés vers le bas et forment un angle θ avec les parois 34 ou 36 à partir desquelles ils s'étendent, l'angle θ est inférieur ou égal à 90°.The example of figure 11D has hooking reliefs 32 reported on the walls 34 and 36 of the body 23. The hooking reliefs 32 are formed by cutting and folding plates 72 and 74 fitting on the side walls 34 and 36 of the body 23. The The hooking reliefs are formed of portions of the plates 72 and 74 folded towards the inside of the cavity. The attachment reliefs 32 are oriented downwards and form an angle θ with the walls 34 or 36 from which they extend, the angle θ is less than or equal to 90 °.

La ou les premières faces 46 ou 46a et 46b de chaque relief d'accrochage 32 de la figure 11E sont convexes vers l'extérieur.The first face or faces 46 or 46a and 46b of each attachment relief 32 of the figure 11E are convex outward.

La deuxième face 48 de chaque relief d'accrochage 32 de la figure 11F forme un angle β avec l'axe d'insertion X qui est inférieur à 90°. Le relief d'accrochage 32 comporte donc une première portion 32a croissante vers le fond 42 et de longueur l1 et une deuxième portion 32b décroissante vers le fond 42 et de longueur l2 . Le rapport des longueurs l2 /l1 est inférieur à 0,2.The second face 48 of each attachment relief 32 of the figure 11F forms an angle β with insertion axis X that is less than 90 °. The attachment relief 32 thus comprises a first portion 32a increasing toward the bottom 42 and of length l 1 and a second portion 32b decreasing towards the bottom 42 and length l 2 . The ratio of lengths l 2 / l 1 is less than 0.2.

La première face 46, 60 ou 62 de chaque relief d'accrochage 32 de la figure 11G est concave vers l'extérieur.The first face 46, 60 or 62 of each attachment relief 32 of the figure 11G is concave towards the outside.

L'exemple de la figure 11H présente des reliefs d'accrochage 32 sous forme de patte perpendiculaire à l'axe d'insertion X disposé dans un renfoncement 74 de la paroi 34 ou 36. Ces derniers sont déformables élastiquement. Lors de l'insertion de l'organe d'application 26, les reliefs d'accrochage 32 peuvent se courber vers le fond de la cavité 30 de sorte que l'angle β devient supérieur à 90°. Lors de l'extraction de l'organe d'application 26, les reliefs d'accrochage 32 peuvent se déformer vers l'ouverture 31 de sorte que l'angle β diminue et, en se déformant, compriment davantage l'organe d'application 26, rendant son extraction plus difficile.The example of figure 11H has hooking projections 32 in the form of tab perpendicular to the insertion axis X disposed in a recess 74 of the wall 34 or 36. The latter are elastically deformable. During the insertion of the applicator member 26, the attachment projections 32 may bend towards the bottom of the cavity 30 so that the angle β becomes greater than 90 °. During the extraction of the applicator member 26, the attachment reliefs 32 may deform towards the opening 31 so that the angle β decreases and, by deforming, further compress the application member. 26, making its extraction more difficult.

Dans l'exemple illustré sur la figure 11I, le corps 23 comporte, en vis-à-vis des reliefs d'accrochage 32, des reliefs de compression 76. Ces derniers permettent lors de l'insertion de l'organe d'application 26 dans la cavité 30 de comprimer ce dernier contre le relief d'accrochage 32 qui lui fait face pour améliorer encore le maintien de l'organe d'application 26. Ici, les reliefs de compression 76 s'étendent sur toute la longueur H de la cavité 30 et présentent une forme symétrique selon leur axe médian et en forme de coussinet.In the example shown on the figure 11I , the body 23 comprises, vis-à-vis the attachment reliefs 32, compression reliefs 76. These allow during the insertion of the applicator member 26 into the cavity 30 to compress the latter against the engaging relief 32 which faces it to further improve the retention of the applicator member 26. Here, the compression reliefs 76 extend over the entire length H of the cavity 30 and have a symmetrical shape according to their median and pillow-shaped axis.

Dans les exemples illustrés sur les figures 11J à 11M, le relief d'accrochage 32 est un relief du fond 42 qui se présente sous la forme d'une flèche ayant la pointe 80 orientée vers l'ouverture 31 de la cavité 30. L'extrémité distale 82 de la flèche, s'étendant sur une longueur l1 , est portée par un pied 84 d'épaisseur constante. Cette dernière s'élargie de la pointe 80 en direction du fond 42. Le pied 84 est d'épaisseur constante et est moins épais que la plus grande épaisseur emax de l'extrémité distale 82. En partant de la pointe 80 vers la base du pied 84, l'épaisseur est croissante sur la longueur l1 de l'extrémité distale 82 puis constante sur la longueur l3 correspondant à au moins une partie du pied 84. L'extrémité distale 82 peut être en forme de V inversé, comme illustré sur la figure 11J, en forme de triangle, comme illustré sur la figure 11K, ou en forme de V inversé avec des rebords parallèles au fond 42 à chacune des extrémités du V, comme illustré sur la figure 11L. L'extrémité distale peut, comme illustré sur la figure 11M, présenter, à la pointe 80, un évidement 86.In the examples illustrated on the Figures 11J to 11M , the hooking relief 32 is a relief of the bottom 42 which is in the form of an arrow having the tip 80 facing the opening 31 of the cavity 30. The distal end 82 of the boom, extending over a length l 1 , is carried by a foot 84 of constant thickness. The latter widens from the tip 80 towards the bottom 42. The foot 84 is of constant thickness and is thinner than the largest thickness e max of the distal end 82. Starting from the tip 80 towards the base the foot 84, the thickness is increasing along the length l 1 of the distal end 82 and constant over the length l 3 corresponding to at least a portion of the foot 84. The distal end 82 may be inverted V-shaped, as illustrated on the figure 11J , in the form of a triangle, as illustrated on the figure 11K , or inverted V-shaped with flanges parallel to the bottom 42 at each end of the V, as shown in FIG. figure 11L .
