Description

La présente invention concerne des perfectionnements apportés aux dispositifs protecteurs permettant d'effectuer une permanente sur un cheveu uniquement au voisinage de la racine de celui-ci et de soustraire à l'action du produit permanente la partie du cheveu non située au voisinage de la racine, ces dispositifs comprenant

  • - une partie rigide ou semi-rigide présentant une forme incurvée en gouttière,
  • - une feuille souple et imperméable de forme sensiblement quadrangulaire, dont un premier bord est solidaire de la susdite partie rigide,
  • - et une partie absorbante, apte à absorber du produit à permanente, associée à un second bord de la feuille souple opposé au susdit premier bord.
The present invention relates to improvements made to the protective devices making it possible to effect a perm on a hair only in the vicinity of the root thereof and to remove from the action of the permanent product the part of the hair not situated in the vicinity of the root , these devices comprising
  • - a rigid or semi-rigid part having a curved gutter shape,
  • - a flexible and impermeable sheet of substantially quadrangular shape, a first edge of which is integral with the said rigid part,
  • - And an absorbent part, able to absorb product with perm, associated with a second edge of the flexible sheet opposite to the above first edge.

Un tel dispositif est par exemple décrit dans la demande de brevet FR-A-2.431.845.Such a device is for example described in patent application FR-A-2,431,845.

L'invention a essentiellement pour but de perfectionner ces dispositifs protecteurs connus principalement pour qu'ils soient mieux adaptés aux diverses exigences de la pratique et qu'ils puissent en particulier être utilisés et mis en place sans requérir de précautions et d'attentions spéciales de la part de l'utilisateur, tout en procurant l'effet recherché, savoir la protection de la partie non traitée du cheveu contre l'action du produit à permanente.The object of the invention is essentially to improve these protective devices which are known mainly so that they are better suited to the various requirements of the practice and that they can in particular be used and put in place without requiring special precautions and attention. on the part of the user, while providing the desired effect, namely the protection of the untreated part of the hair against the action of the product with perm.

A ces fins, les perfectionnements apportés conformément à l'invention consistent en ce que entre la feuille souple et la partie absorbante, est disposée une seconde partie rigide ou semi- rigide présentant une forme incurvée en gouttière solidarisée par un de ses bords (premier bord) à la feuille souple et portant, solidarisée le long de son bord opposé (second bord), la partie absorbante, et en ce que la seconde partie rigide présente à ou vers ses deux extrémités, respectivement deux pinces d'accrochage s'étendant sur un arc de cercle d'au moins 180° et constituées en un matériau élastiquement déformable.For these purposes, the improvements made in accordance with the invention consist in that between the flexible sheet and the absorbent part, there is disposed a second rigid or semi-rigid part having a curved shape in gutter secured by one of its edges (first edge ) to the flexible and carrying sheet, secured along its opposite edge (second edge), the absorbent part, and in that the second rigid part has, at or towards its two ends, respectively two gripping clips extending over an arc of a circle of at least 180 ° and made of an elastically deformable material.

Grâce à cet agencement, on est assuré que, quelle que soit la position de la partie absorbante sur le pourtour du bigoudi, une fois le dispositif protecteur enroulé avec le cheveu en position fonctionnelle autour du bigoudi, cette partie absorbante sera maintenue appliquée contre le cheveu et pourra jouer son rôle de façon efficace.Thanks to this arrangement, it is ensured that, whatever the position of the absorbent part on the periphery of the curler, once the protective device wound with the hair in a functional position around the curler, this absorbent part will be kept applied against the hair. and can play its role effectively.

Eventuellement, on peut encore améliorer le contact de la partie absorbante sur le cheveu par le fait que, entre les deux pinces d'accrochage, sont prévus des doigts de maintien saillant sur le second bord de la seconde partie rigide et constitués également en un matériau élastiquement déformable. Ainsi, la partie absorbante est maintenue en appui sur le cheveu sur toute sa longueur et son efficacité s'en trouve encore accrue.Optionally, it is possible to further improve the contact of the absorbent part on the hair by the fact that, between the two attachment clips, protruding holding fingers are provided on the second edge of the second rigid part and also made of a material. elastically deformable. Thus, the absorbent part is held in abutment on the hair over its entire length and its effectiveness is further increased.

De préférence, pour des raisons de simplicité de fabrication, les deux pinces d'accrochage et éventuellement les doigts de maintien sont constitués d'un seul tenant avec la seconde partie rigide.Preferably, for reasons of simplicity of manufacture, the two attachment clips and possibly the retaining fingers are made in one piece with the second rigid part.

Il est en outre intéressant de prévoir un organe de réglage amovible en forme de gouttière s'étendant sur un arc de cercle d'au moins 180°, muni le long d'un de ses bords longitindinaux d'une partie absorbante et constitué en un matériau élastiquement déformable. Grâce à cet organe, l'utilisateur n'est plus contraint à une mise en place précise du dispositif protecteur sur le cheveu à traiter pour parvenir à ne laisser dépasser que la longueur exacte du cheveu, au voisinage de la racine, qui doit être traitée: il peut maintenant procéder à une mise en place approximative du dispositif protecteur, puis coiffer l'ensemble enroulé sur le bigoudi à l'aide de l'organe de réglage avec la partie absorbante de celui-ci disposée vers la racine du cheveu, et faire enfin tourner cet organe pour amener sa partie absorbante à l'endroit précis où doit s'arrêter l'action du produit à permanente; autrement dit il peut, de façon précise et continue, ajuster la longueur de la partie du cheveu voisine de la racine qui doit être traitée.It is also advantageous to provide a removable adjustment member in the form of a gutter extending over an arc of a circle of at least 180 °, provided along one of its longitudinal edges with an absorbent part and consisting of a elastically deformable material. Thanks to this organ, the user is no longer forced to place the protective device precisely on the hair to be treated so as to allow only the exact length of the hair to exceed, in the vicinity of the root, which must be treated. : it can now proceed to an approximate positioning of the protective device, then cap the whole wound on the curler using the adjusting member with the absorbent part thereof disposed towards the hair root, and finally rotate this member to bring its absorbent part to the precise place where the action of the product must stop permanently; in other words, it can, precisely and continuously, adjust the length of the part of the hair close to the root which must be treated.

Pour faciliter le déplacement tournant de l'organe de réglage, on peut avantageusement prévoir des moyens de guidage qui comprennent au moins deux tétons radiaux portés par l'organe de réglage ou les pinces d'accrochage de la seconde partie rigide ou semi-rigide et au moins deux lumières allongées circonférentiellement aptes à recevoir les susdits tétons et portées respectivement par les pinces d'accrochage sur l'organe de réglage.To facilitate the rotary movement of the adjustment member, it is advantageously possible to provide guide means which comprise at least two radial pins carried by the adjustment member or the attachment clips of the second rigid or semi-rigid part and at least two elongated slots circumferentially adapted to receive the aforesaid nipples and carried respectively by the grippers on the adjustment member.

Il est intéressant que la face interne de chaque partie absorbante soit imperméable au produit à permanente dans sa partie postérieure et ne soit perméable que dans son bord antérieur et/ou au voisinage dudit bord. De la sorte, on peut donner à chaque partie absorbante un volume suffisant pour que le dispositif soit efficace sans toutefois que, malgré les dimensions qui en résultent, la partie protégée du cheveu soit mise en contact avec la partie absorbante imbibée du produit à permanente.It is advantageous that the internal face of each absorbent part is impermeable to the permanent product in its posterior part and is only permeable in its anterior edge and / or in the vicinity of said edge. In this way, each absorbent part can be given sufficient volume for the device to be effective without, however, despite the resulting dimensions, the protected part of the hair being brought into contact with the absorbent part soaked in the permanent product.

D'une façon avantageuse, le bord antérieur de chaque partie absorbante est renflé pour former un bourrelet s'appliquant élastiquement, en position de montage, contre le cheveu.Advantageously, the front edge of each absorbent part is bulged to form a bead which is applied elastically, in the mounting position, against the hair.

Pour éviter la nécessité de sélectionner des bigoudis de diamètres différents selon l'emplacement du cheveu à traiter sur la tête, on prévoit que la première partie rigide ou semi- rigide possède, vers ses extrémités latérales, une épaisseur supérieure à celle de sa zone centrale, et il est prévu deux pattes incurvées prolongeant respectivement les zones plus épaisses et articulées en rotation sur la partie rigide de manière, en position de montage, à fermer l'intervalle entre les bords en regard de la partie rigide et offrir à la feuille souple un appui continu dans ces zones d'extrémité. Ainsi, en prévoyant des dispositifs protecteurs ayant des parties rigides avec des extrémités latérales de différentes épaisseurs (par exemple trois types différents en pratique), il est possible d'utiliser un seul type de bigoudi de diamètre donné, ce qui simplifie notablement le travail de l'utilisateur qui n'a plus à apparier les dispositifs protecteurs avec les bigoudis de diamètre correspondant.To avoid the need to select curlers of different diameters according to the location of the hair to be treated on the head, it is provided that the first rigid or semi-rigid part has, towards its lateral ends, a thickness greater than that of its central zone. , and two curved tabs are provided respectively extending the thicker and articulated areas in rotation on the rigid part so as, in the mounting position, to close the gap between the opposite edges of the rigid part and to offer the flexible sheet continuous support in these end zones. Thus, by providing protective devices having rigid parts with lateral ends of different thicknesses (for example three types different in practice), it is possible to use a single type of curler of given diameter, which considerably simplifies the work of the user who no longer has to pair the protective devices with the curlers of corresponding diameter.

Pour faciliter la mise en place du dispositif protecteur sur le bigoudi, on peut prévoir que les bords latéraux de la première et/ou de la seconde partie rigide ou semirigide sont munis d'un rabat radial continu ou discontinu constituant une butée axiale en position de montage sur le bigoudi, ou bien encore, selon une variante, que les zones relativement plus rigides sont situées le long des deux bords latéraux de la feuille, et que la feuille présente alors des rabats latéraux, continus ou discontinus, constituant une butée axiale en position de montage sur le bigoudi.To facilitate the installation of the protective device on the curler, provision may be made for the lateral edges of the first and / or of the second rigid or semi-rigid part to be provided with a continuous or discontinuous radial flap constituting an axial stop in the position of mounting on the curler, or alternatively, according to a variant, that the relatively more rigid zones are situated along the two lateral edges of the sheet, and that the sheet then has lateral flaps, continuous or discontinuous, constituting an axial stop in mounting position on the curler.

L'invention sera mieux comprise à la lecture de la description qui suit de certains de ses modes de réalisation, donnés uniquement à titre d'exemple illustratif, et dans laquelle on se réfère aux dessins annexés sur lesquels:

  • - la figure 1 montre, en vue perspective, un dispositif protecteur agencé conformément à l'invention,
  • - la figure 2 montre, en vue perspective, un autre mode de réalisation d'une partie du dispositif de la figure 1,

The invention will be better understood on reading the following description of some of its embodiments, given solely by way of illustrative example, and in which reference is made to the appended drawings in which:
  • FIG. 1 shows, in perspective view, a protective device arranged in accordance with the invention,
  • FIG. 2 shows, in perspective view, another embodiment of part of the device of FIG. 1,
  • FIG. 3 shows, in perspective view, another element according to the invention usable with the device of FIG. 1 or the variant of FIG. 2,
  • FIG. 4 illustrates, in cross section, the protective device of FIGS. 1 or 2 mounted in the functional position in association with the element of FIG. 3, and
  • - Figure 5 shows another variant of a part of the device of Figure 1.

En se reportant tout d'abord à la figure 1, le dispositif protecteur de l'invention comprend une partie 20 allongée en forme de gouttière, incurvée sur au moins 180° pour faciliter la mise en place initiale du dispositif protecteur sur le bigoudi. Cette partie 20 est constituée en un matériau, de préférence une matière plastique, rigide ou semi-rigide élastiquement déformable.Referring first to FIG. 1, the protective device of the invention comprises an elongated part 20 in the form of a gutter, curved over at least 180 ° to facilitate the initial positioning of the protective device on the curler. This part 20 is made of a material, preferably a plastic, rigid or semi-rigid elastically deformable.

Le long d'un bord longitudinal de la partie 20 est solidarisée une feuille souple protectrice 21, imperméable aux liquides et constituée en matériau très souple possédant la propriété d'adhérer légèrement aux corps sur lesquels elle est appliquée (par exemple du polychlorure de vinyle de quelques dizaines - typiquement 10 à 20 - de microns d'épaisseur).Along a longitudinal edge of the part 20 is secured a flexible protective sheet 21, impermeable to liquids and made of very flexible material having the property of adhering slightly to the bodies to which it is applied (for example polyvinyl chloride of a few tens - typically 10 to 20 - microns thick).

Bien que la feuille 21 puisse être entièrement souple, il est toutefois avantageux, pour faciliter son enroulement avec la partie du cheveu à protéger, qu'elle possède deux bandes latérales 32 sensiblement plus rigides (voir figure 1): cette rigidité accrue peut être obtenue soit par collage de deux bandes de renforcement sur la feuille 21, soit de préférence par différenciation de densité du matériau au cours de la fabrication de la feuille.Although the sheet 21 can be entirely flexible, it is however advantageous, to facilitate its winding with the part of the hair to be protected, that it has two substantially more rigid lateral bands 32 (see FIG. 1): this increased rigidity can be obtained either by bonding two reinforcing strips to the sheet 21, or preferably by differentiating the density of the material during the manufacture of the sheet.

Cette feuille présente une forme sensiblement rectangulaire et, le long de son bord opposé à celui lié à la partie 20, elle est solidarisée à des moyens absorbants agencés pour, lorsque le dispositif protecteur est en position fonctionnelle, empêcher le liquide à permanente de remonter par capillarité le long du cheveu.This sheet has a substantially rectangular shape and, along its edge opposite to that linked to the part 20, it is secured to absorbent means arranged to, when the protective device is in the functional position, prevent the permanent liquid from rising by capillarity along the hair.

Ces moyens comprennent une seconde partie 22 allongée et incurvée en forme de gouttière, solidarisée, le long d'un de ses bords longituidinaux, à la, feuille souple 21 et munie, sur sa face intérieure et le long de son autre bord longitudinal, d'une bande 23 de matière absorbante telle qu'une mousse synthétique.These means comprise a second elongated and curved second portion 22 in the form of a gutter, secured along one of its longitudinal edges to the flexible sheet 21 and provided, on its inner face and along its other longitudinal edge, d 'A strip 23 of absorbent material such as synthetic foam.

A ses deux extrémités, la partie 22 en forme de gouttière est munie respectivement de deux prolongements 24 incurvés selon un arc de cercle d'au moins 180°.At its two ends, the gutter-shaped part 22 is respectively provided with two curved extensions 24 in an arc of a circle of at least 180 °.

Ces prolongements 24 constituent des pinces élastiquement déformables aptes, en position fonctionnelle du dispositif protecteur sur un bigoudi, à enserrer les extrémités correspondantes du bigoudi: ainsi, on est assuré que la bande 23 de matière absorbante reste appliquée contre le cheveu et est en position pour assurer son rôle qui est d'empêcher le liquide à permanente, déposé sur la partie dégagée du cheveu voisine de la racine, de remonter par capillarité dans la région du cheveu qui ne doit pas être soumise à l'action de ce produit.These extensions 24 constitute elastically deformable pliers capable, in the functional position of the protective device on a curler, of enclosing the corresponding ends of the curler: thus, it is ensured that the strip 23 of absorbent material remains applied against the hair and is in position for ensure its role which is to prevent the liquid to permanent, deposited on the released part of the hair close to the root, from going up by capillarity in the region of the hair which should not be subjected to the action of this product.

La figure 2 montre une variante des dispositions prévues à la figure 1: entre les prolongements d'extrémites 24, des doigts 25 incurvés dans le même sens que les prolongements 24 s'étendent à partir du bord de la partie 22 en forme de gouttière, sur une longueur toutefois inférieure à celle des prolongements 24. Les doigts 25, au nombre par exemple de un à trois, contribuent à maintenir la bande 23 en matière absorbante sur le cheveu.FIG. 2 shows a variant of the arrangements provided in FIG. 1: between the end extensions 24, fingers 25 curved in the same direction as the extensions 24 extend from the edge of the part 22 in the form of a gutter, over a length, however, less than that of the extensions 24. The fingers 25, for example one to three in number, help to maintain the strip 23 of absorbent material on the hair.

Les prolongements 24 et les doigts 25 sont constitués d'un seul tenant avec la partie 22 en forme de gouttière, laquelle peut être constituée en tout matériau élastiquement déformable.The extensions 24 and the fingers 25 are made in one piece with the part 22 in the form of a gutter, which can be made of any elastically deformable material.

Grâce à ces agencements, on est assuré que la bande 23 en matériau absorbant restera appliquée sur le cheveu quelle que soit la position où elle se trouvera, en position fonctionnelle, sur le pourtour du bigoudi.Thanks to these arrangements, it is ensured that the strip 23 of absorbent material will remain applied to the hair regardless of the position in which it is found, in the functional position, around the periphery of the curler.

Pour faciliter la mise en place du dispositif sur le bigoudi et le maintenir axialement sur ce dernier, on prévoit des moyens de butée axiale constitués par un rabat radial soit de la partie allongée 20 (comme représenté en 33 à la figure 1), soit de la partie allongée 22, soit enfin de la feuille 21 elle-même lorsqu'elle est munie de bandes de renforcement 32.To facilitate the positioning of the device on the curler and to keep it axially on the latter, axial stop means are provided, constituted by a radial flap either of the elongated part 20 (as shown at 33 in FIG. 1), or of the elongated part 22, or finally of the sheet 21 itself when it is provided with reinforcing strips 32.

La figure 3 montre un organe de réglage 26 constitué par une feuille de matériau rigide ou semi-rigide élastiquement déformable et incurvé en gouttière sur un arc de cercle d'au moins 180°. Une bande 27 de matière absorbante est fixée sur la face intérieure de cet organe, le long de l'un de ses bords longitudinaux.FIG. 3 shows an adjustment member 26 consisting of a sheet of rigid or semi-rigid material which is elastically deformable and curved in a gutter on an arc of a circle of at least 180 °. A strip 27 of absorbent material is fixed on the inner face of this member, along one of its longitudinal edges.

Comme représenté à la figure 4, on commence par enrouler autour du bigoudi 28 la partie 29 à protéger du cheveu en même temps qu'on enroule le dispositif protecteur 20 à 24. Seule dépasse une portion 31 du cheveu comprise entre la racine et la bande absorbante 23. On met alors en place l'organe 26 en le déformant élastiquement pour qu'il enserre l'ensemble construit autour du bigoudi 28 de manière telle que sa bande absorbante 27 soit située du côté de la racine du cheveu. En faisant ensuite tourner l'organe dans le sens et de l'amplitude appropriés, il est possible d'ajuster de façon simple et précise la longueur du cheveu restée accessible pour être soumise à l'action du produit à permanente. De ce fait, il n'est pas nécessaire que l'utilisateur effectue une mise en place précise du dispositif protecteur sur le cheveu avant son enroulement sur le bigoudi; cette mise en place peut n'être qu'approximative et l'ajustement précis est obtenu par la rotation de l'organe 26.As shown in Figure 4, we start by wrapping around the curler 28 the part 29 to protect the hair at the same time as the protective device 20 to 24 is wound. Only exceeds a portion 31 of the hair between the root and the strip absorbent 23. The member 26 is then put in place by deforming it elastically so that it encloses the assembly constructed around the curler 28 so that its absorbent strip 27 is located on the side of the hair root. By then rotating the member in the appropriate direction and amplitude, it is possible to adjust in a simple and precise manner the length of the hair remaining accessible to be subjected to the action of the product to perm. Therefore, it is not necessary that the user performs a precise positioning of the protective device on the hair before it is wound on the curler; this positioning may be only approximate and the precise adjustment is obtained by the rotation of the member 26.

Pour procurer une transition mette entre la partie du cheveu à protéger et la partie à traiter, on prévoit que le bord antérieur de la bande absorbante soit agencé sous forme d'un bourrelet saillant. Si une telle disposition est envisageable pour la bande absorbante 23 portée par la partie rigide 22, elle est surtout intéressante pour la bande absorbante 27 portée par l'organe de réglage 26: ce bourrelet est désigné par 34 à la figure 4.To provide a smooth transition between the part of the hair to be protected and the part to be treated, provision is made for the front edge of the absorbent strip to be arranged in the form of a protruding bead. If such an arrangement is possible for the absorbent strip 23 carried by the rigid part 22, it is especially advantageous for the absorbent strip 27 carried by the adjusting member 26: this bead is designated by 34 in FIG. 4.

Pour accroître la protection de la partie du cheveu ne devant pas être traitée, on prévoit que les bandes absorbantes 23 et/ou 27 sont, sur leur face intérieure, rendues partiellement imperméables, par exemple par adjonction d'une feuille imperméable 35 pour la bande absorbante 23 (figures 1 et 4) et/ou 36 pour la bande absorbante 27 (figure 4) ne laissant dégagée que la bordure antérieure de ces bandes absorbantes. On évite ainsi que chacune de ces bandes absorbantes, une fois imbibée du produit à permanente, soit en contact avec la partie du cheveu ne devant pas être traitée.To increase the protection of the part of the hair which is not to be treated, provision is made for the absorbent strips 23 and / or 27 to be made partially impermeable on their inner face, for example by adding an impermeable sheet 35 to the band. absorbent 23 (FIGS. 1 and 4) and / or 36 for the absorbent strip 27 (FIG. 4) leaving only the front edge of these absorbent strips released. This prevents each of these absorbent strips, once soaked with the product to permanent, is in contact with the part of the hair not to be treated.

Pour faciliter le déplacement en rotation de l'organe de réglage 26 et permettre son positionnement angulaire précis, on prévoit un système de guidage comportant par exemple, comme représenté aux figures 2 et 3, deux tétons 37 saillant radialement sur la face externe des prolongements 24 et deux lumières allongées 38 s'étendant selon la circonférence de l'organe de réglage 26.To facilitate the rotational movement of the adjustment member 26 and allow its precise angular positioning, there is provided a guide system comprising for example, as shown in Figures 2 and 3, two pins 37 projecting radially on the outer face of the extensions 24 and two elongated slots 38 extending along the circumference of the adjusting member 26.

Enfin, comme représenté à la figure 5, on prévoit que la partie rigide ou semi-rigide 20 soit équipée, au voisinage de ses extrémités, de cales curvilignes 39 épousant circonférentiellement le contour de la partie 20. Ces cales présentent une forme curviligne ouverte pour permettre la mise en place de la partie 20 sur le bigoudi et une portion mobile 40, raccordée de façon articulée en rotation, peut être rabattue pour obtenir une cale présentant un contour fermé offrant un appui circonférentiel continu pour l'enroulement de la feuille 21. En disposant de plusieurs (par exemple trois ou quatre) types de dispositifs protecteurs dont les parties rigides ou semi- rigides 20 sont équipées de cales curvilignes d'épaisseurs différentes, on peut enrouler les cheveux sur des diamètres différents tout en n'employant qu'un seul type de bigoudi. Il en résulte une simplification du travail de l'utilisateur.Finally, as shown in FIG. 5, provision is made for the rigid or semi-rigid part 20 to be fitted, in the vicinity of its ends, with curvilinear wedges 39 which circumferentially follow the contour of the part 20. These wedges have an open curvilinear shape for allow the setting up of the part 20 on the curler and a movable portion 40, connected in an articulated manner in rotation, can be folded down to obtain a wedge having a closed contour offering a continuous circumferential support for the winding of the sheet 21. By having several (for example three or four) types of protective devices whose rigid or semi-rigid parts 20 are equipped with curvilinear shims of different thicknesses, it is possible to wind the hair to different diameters while using only only one type of curler. This results in a simplification of the work of the user.
