Description
La présente invention concerne un ensemble de conditionnement de produits pour l'éclaircissement ou la décoloration des cheveux et un procédé pour éclaircir ou décolorer les cheveux au moyen d'un tel ensemble. Dans la présente description et dans les revendications, on utilisera indifféremment les termes "éclaircir" et "décolorer" les deux notions ne se différenciant que par l'importance du changement de teinte et correspondant donc à la même action à des degrés différents.The present invention relates to a set for packaging products for lightening or bleaching the hair and a method for lightening or bleaching the hair by means of such a set. In the present description and in the claims, the terms "lighten" and "discolor" will be used interchangeably, the two concepts differing only in the extent of the change in color and therefore corresponding to the same action to different degrees.
A ce jour, pour éclaircir ou décolorer les cheveux, on prépare une pâte obtenue en mélangeant, juste avant emploi, une poudre décolorante contenant un sel peroxygéné et un révélateur, le plus souvent à base d'eau oxygénée, on applique le mélange obtenu, soit sur la totalité de la chevelure, soit sur des mèches, pendant un temps déterminé, puis, pour finir, on rince à l'eau et on sèche les cheveux. Au cours du mélange de la poudre décolorante et du révélateur, il se forme malheureusement un nuage de poudre décolorante, qui est irritant pour les muqueuses nasales et qui dégage une odeur désagréable.To date, to lighten or bleach the hair, a paste obtained is prepared by mixing, just before use, a bleaching powder containing a peroxygenated salt and a developer, most often based on hydrogen peroxide, the mixture obtained is applied, either on the whole of the hair, or on locks, for a determined time, then, finally, rinse with water and dry the hair. During the mixing of the bleaching powder and the developer, unfortunately a cloud of bleaching powder is formed, which is irritating to the nasal mucous membranes and which gives off an unpleasant odor.
Pour pallier cet inconvénient, on a proposé de stocker la poudre décolorante dans un sachet en plastique et d'effectuer le mélange de la poudre décolorante et du révélateur, dans le sachet plastique, par malaxage manuel : un procédé de ce type est décrit dans US-A-4 116 365 et dans US-A-4 506 783. Cependant, le procédé décrit dans les brevets susmentionnés ne permet pas d'éliminer tous les risques de dégagement dans l'atmosphère d'un nuage de poudre décolorante et il correspond, en outre, à des ensembles de conditionnement relativement encombrants.To overcome this drawback, it has been proposed to store the bleaching powder in a plastic bag and to mix the bleaching powder and the developer, in the plastic bag, by manual mixing: a process of this type is described in US -A-4 116 365 and in US-A-4 506 783. However, the method described in the aforementioned patents does not make it possible to eliminate all the risks of release into the atmosphere of a cloud of bleaching powder and it corresponds , in addition, to relatively bulky packaging assemblies.
La présente invention a pour but de proposer un ensemble compact, qui permet d'éliminer totalement le dégagement dans l'atmosphère d'un nuage irritant de poudre décolorante.The object of the present invention is to propose a compact assembly which makes it possible to completely eliminate the release into the atmosphere of an irritating cloud of bleaching powder.
La présente invention a donc pour objet un ensemble de conditionnement de produits pour l'éclaircissement des cheveux contenant, dans un même conteneur, un sachet en plastique souple contenant une poudre décolorante et un récipient contenant un révélateur sous forme fluide, le sachet étant constitué par un sac en matière plastique souple, fixé sur une tête en matière plastique rigide comportant un élément annulaire formant goulot muni d'au moins un filetage, le sachet étant fermé par un capuchon vissé sur ledit élément annulaire ; caractérisé par le fait que le récipient est un tube en matière souple contenant le révélateur sous forme de crème, ce tube comportant un goulot muni d'un filetage, qui est susceptible de coopérer avec un filetage de l'élément annulaire, le tube étant fermé par un bouchon vissé sur le filetage de son goulot ; et qu'au moins un élément du conteneur constitue une barquette susceptible de recevoir le mélange de la poudre et du révélateur en vue de son application sur les cheveux.The present invention therefore relates to a set of packaging products for lightening hair containing, in the same container, a flexible plastic bag containing a bleaching powder and a container containing a developer in fluid form, the sachet being constituted by a flexible plastic bag, fixed on a rigid plastic head comprising an annular element forming a neck provided with at least one thread, the sachet being closed by a cap screwed onto said annular element; characterized in that the container is a tube made of flexible material containing the developer in the form of a cream, this tube comprising a neck provided with a thread, which is capable of cooperating with a thread of the annular element, the tube being closed by a plug screwed onto the thread of its neck; and that at least one element of the container constitutes a tray capable of receiving the mixture of the powder and of the developer with a view to its application to the hair.
Dans la présente demande et dans les revendications, on entend par "révélateur sous forme de crème" un révélateur sous forme de pâte visqueuse ou de gel visqueux, mais cependant fluide.In the present application and in the claims, the expression "developer in the form of a cream" means a developer in the form of a viscous paste or a viscous gel, but nevertheless fluid.
Dans cet ensemble de conditionnement, le sachet comporte un élément annulaire muni d'un filetage susceptible de coopérer avec le filetage du goulot du tube contenant le révélateur sous forme de crème ; il est ainsi possible d'éviter tout dégagement de nuage de substance décolorante lors du mélange de celle-ci avec le révélateur. En effet, selon l'invention, après avoir dévissé le capuchon fixé sur le sachet et le bouchon fixé sur le tube, on visse le goulot du tube sur l'élément annulaire du sachet et en comprimant le tube, on introduit dans le sachet le révélateur initialement contenu dans le tube, sans que le produit pulvérulent puisse se dégager du sachet car celui-ci est obturé par le tube pendant l'opération ; de plus, le révélateur étant sous forme de crème, il se dépose sur la poudre en formant une couche qui empêche tout dégagement d'un nuage de poudre dans le sachet ; il en résulte qu'aucune particule de poudre ne peut s'échapper hors du sachet au moment où on ouvre ledit sachet. De plus, étant donné que l'utilisateur ferme ensuite le sachet à l'aide du capuchon, avant de procéder au malaxage, il ne peut pas non plus y avoir formation d'un nuage de produit pulvérulent au stade du malaxage.In this packaging unit, the sachet comprises an annular element provided with a thread capable of cooperating with the thread of the neck of the tube containing the developer in the form of a cream; it is thus possible to avoid any release of cloud of bleaching substance when mixing it with the developer. In fact, according to the invention, after having unscrewed the cap fixed on the bag and the stopper fixed on the tube, the neck of the tube is screwed onto the annular element of the bag and by compressing the tube, the developer initially contained in the tube, without the pulverulent product being able to be released from the sachet because the latter is closed by the tube during the operation; moreover, the developer being in the form of a cream, it is deposited on the powder, forming a layer which prevents any release of a cloud of powder in the sachet; as a result, no powder particles can escape from the sachet when the sachet is opened. In addition, since the user then closes the sachet using the cap, before mixing, there can also be no formation of a cloud of powdery product at the mixing stage.
Selon un mode de réalisation préféré de l'ensemble selon l'invention, le goulot du tube comporte un filetage externe, le capuchon du sachet comporte un filetage interne et l'élément annulaire comporte, d'une part, un filetage externe qui est susceptible de coopérer avec le filetage du capuchon et d'autre part, un filetage interne qui est susceptible de coopérer avec le filetage du goulot du tube. Avantageusement, dans le conteneur, la poudre décolorante est disposée dans le fond du sac, celui-ci étant plié de façon que sa partie contenant la poudre soit disposée en vis-à-vis d'une première partie vide dudit sac située au voisinage de la tête de fixation du sachet et, entre la partie du sac contenant la poudre et la pliure du sac, il existe une deuxième partie vide, qui est en vis-à-vis d'une zone de la première partie vide du sac, le tube étant disposé au droit de la zone où les première et deuxième parties vides susmentionnées se font vis-à-vis, parallèlement à la pliure du sac. Cette disposition, dans laquelle le sac est replié et dans laquelle le tube est disposé contre deux zones vides superposées du sac replié, qui ont, par conséquent, une faible épaisseur, permet de diminuer sensiblement le volume du conteneur et d'obtenir un ensemble compact.According to a preferred embodiment of the assembly according to the invention, the neck of the tube has an external thread, the cap of the bag has an internal thread and the annular element comprises, on the one hand, an external thread which is capable of cooperating with the thread of the cap and on the other hand, an internal thread which is capable of cooperating with the thread of the neck of the tube. Advantageously, in the container, the bleaching powder is placed in the bottom of the bag, the latter being folded so that its part containing the powder is placed opposite a first empty part of said bag located in the vicinity of the fixing head of the bag and, between the part of the bag containing the powder and the fold of the bag, there is a second empty part, which is opposite an area of the first empty part of the bag, the tube being arranged in line with the area where the first and second empty parts mentioned above are opposite, parallel to the fold of the bag. This arrangement, in which the bag is folded and in which the tube is placed against two superimposed empty zones of the folded bag, which therefore have a small thickness, makes it possible to significantly reduce the volume of the container and to obtain a compact assembly. .
Dans le cas où une certaine quantité d'eau doit être ajoutée au mélange pour obtenir un mélange plus ou moins fluide selon son utilisation, l'ensemble de conditionnement comporte un doseur qui est, de préférence, muni d'au moins un niveau de dosage et d'un bec verseur. Ce doseur est, avantageusement, fixé de manière détachable à l'extérieur du conteneur. Il faut noter que, selon l'invention, le révélateur étant sous forme de crème, il est possible de l'introduire dans l'ensemble de conditionnement en utilisant un tube qui contient le révélateur. Si l'on désire obtenir un mélange plus fluide, on introduit de l'eau ultérieurement au moyen du doseur susmentionné. On évite ainsi d'avoir à stocker un révélateur liquide dans un flacon rigide, ce qui nécessiterait un ensemble de conditionnement plus volumineux.In the event that a certain amount of water has to be added to the mixture in order to obtain a more or less fluid mixture depending on its use, the packaging assembly comprises a metering device which is preferably provided with at least one dosage level. and a spout. This dispenser is advantageously fixed detachably outside the container. It should be noted that, according to the invention, the developer being in the form of a cream, it is possible to introduce it into the packaging assembly using a tube which contains the developer. If it is desired to obtain a more fluid mixture, water is introduced subsequently using the aforementioned metering device. This avoids having to store a liquid developer in a rigid bottle, which would require a larger packaging unit.
Le conteneur est, de préférence, constitué par une coque en plastique rigide ou semi-rigide munie d'un couvercle détachable, l'ensemble ayant, en général, la forme d'un prisme ou cylindre droit. La coque peut être utilisée comme barquette pour verser le mélange obtenu par malaxage avant de le prélever et de l'appliquer sur les cheveux. Selon un mode de réalisation préféré, lorsque l'ensemble comporte un doseur, le conteneur a la forme d'un prisme droit à base polygonale dont deux faces adjacentes forment entre elles, à l'extérieur du conteneur, un angle inférieur à 180° pour constituer à l'extérieur du conteneur un logement permettant le positionnement du doseur.The container is preferably constituted by a rigid or semi-rigid plastic shell provided with a detachable cover, the assembly having, in general, the shape of a right prism or cylinder. The shell can be used as a tray to pour the mixture obtained by kneading before removing it and applying it to the hair. According to a preferred embodiment, when the assembly includes a metering device, the container has the shape of a straight prism based polygonal of which two adjacent faces form between them, outside the container, an angle less than 180 ° to constitute outside the container a housing allowing the positioning of the metering device.
Selon un mode de réalisation préféré du sachet, l'extrémité du sac, qui est à l'opposé de la tête de fixation, constitue un fond fermé par une soudure transversale dans laquelle sont scellées deux à quatre barrettes rigides dont la longueur totale est au moins égale aux deux tiers de la largeur du sac au niveau dudit fond. Les barrettes sont, de préférence, en matière plastique rigide. La présence de ces barrettes séparées permet de malaxer le sachet dans le sens de la largeur car le sac peut se plier longitudinalement entre deux barrettes. Cependant, l'ensemble des barrettes reste suffisamment rigide pour que l'on puisse rouler le sac autour des barrettes pour expulser en totalité le mélange hors du sachet. Avantageusement, la soudure transversale du fond du sac définit avec les bords longitudinaux dudit sac des angles arrondis pour éviter toute rétention de poudre dans les coins du sac.According to a preferred embodiment of the bag, the end of the bag, which is opposite to the fixing head, constitutes a bottom closed by a transverse weld in which two to four rigid bars are sealed, the total length of which is at less equal to two thirds of the width of the bag at said bottom. The bars are preferably made of rigid plastic. The presence of these separate bars makes it possible to knead the bag in the width direction because the bag can fold longitudinally between two bars. However, all of the bars remain rigid enough so that the bag can be rolled around the bars to completely expel the mixture from the sachet. Advantageously, the transverse weld of the bottom of the bag defines with the longitudinal edges of said bag rounded corners to avoid any retention of powder in the corners of the bag.
Le sac est, de préférence, au moins partiellement, en matière plastique transparente de façon à permettre à l'utilisateur de contrôler l'homogénéité du mélange malaxé pendant le malaxage. Selon un mode de réalisation préféré, le sac est composé de deux feuilles de matière plastique, l'une de ces feuilles étant transparente et l'autre opaque : le sac comporte, dans ce cas, deux soudures longitudinales et une soudure de fond transversale.The bag is preferably at least partially made of transparent plastic so as to allow the user to check the homogeneity of the kneaded mixture during kneading. According to a preferred embodiment, the bag is composed of two sheets of plastic, one of these sheets being transparent and the other opaque: the bag comprises, in this case, two longitudinal welds and a transverse bottom weld.
Le sachet a, de préférence, sur une certaine hauteur au voisinage de la tête de fixation, et en projection sur le plan passant par la soudure du fond et par l'axe de la tête de fixation, une largeur décroissante en direction de ladite tête de fixation. Le sachet forme, ainsi, en quelque sorte un entonnoir, ce qui facilite l' écoulement, hors du sachet, du mélange obtenu après malaxage.The bag preferably has, over a certain height in the vicinity of the fixing head, and in projection on the plane passing through the bottom weld and through the axis of the fixing head, a decreasing width in the direction of said head. of fixation. The sachet thus forms, in a way, a funnel, which facilitates the flow, out of the sachet, of the mixture obtained after kneading.
Le sac est, avantageusement, fabriqué à partir d'une ou deux feuilles en matière plastique souple. Ces feuilles peuvent être, par exemple, en polyéthylène, ou en un complexe plastique multicouche constitué de couches de (polyéthylène téréphtalate/polyéthylène) ou de couches de (polyéthylène téréphtalate/polyéthylène/copolymère d'éthylène et d'alcool vinylique/polyéthylène).The bag is advantageously made from one or two sheets of flexible plastic. These sheets can be, for example, made of polyethylene, or a multilayer plastic complex consisting of layers of (polyethylene terephthalate / polyethylene) or layers of (polyethylene terephthalate / polyethylene / copolymer of ethylene and vinyl alcohol / polyethylene).
L'ensemble de conditionnement peut contenir des accessoires, tels que des gants, un bonnet perforé pour la décoloration de mèches, des crochets pour les mèches ou une notice d'utilisation. Il contient généralement aussi un applicateur, tel qu'un pinceau, utilisable indépendamment du sachet ou un applicateur susceptible d'être vissé sur l'élément annulaire du sachet, à la place du capuchon.The packaging set may contain accessories, such as gloves, a perforated cap for bleaching locks, hooks for locks or instructions for use. It generally also contains an applicator, such as a brush, usable independently of the sachet or an applicator capable of being screwed onto the annular element of the sachet, in place of the cap.

Les figures 1 et 2 représentent un ensemble 1 de conditionnement selon l'invention. Cet ensemble est constitué par un conteneur formé par une coque 2 en plastique semi-rigide, dont la base a la forme d'un rectangle, rectangle dont un des angles 8 est échancré de façon à former deux côtés constituant à l'extérieur un angle inférieur à 180° ; les parois latérales de la coque sont perpendiculaires à ses bases. Cette coque 2 est ouverte sur l'une de ses bases et un couvercle 28 vient s'emboîter sur les parois latérales de la coque 2 pour la fermer ; dans une variante, le couvercle 28 pourrait être remplacé par une pellicule pelable thermosoudée sur les bords de la coque 2. Dans la coque 2 sont disposés un sachet 4, un tube 5 et un applicateur constitué par un pinceau 6.Figures 1 and 2 show a package 1 according to the invention. This assembly is constituted by a container formed by a
Dans l'angle 8 échancré de la coque 2 est fixé un doseur 7 qui vient de moulage avec la coque 2 ; ce doseur est rattaché à la coque 2 par des picots 9, qui peuvent être brisés pour détacher le doseur 7 de la coque 2. Le doseur 7 est représenté en détail sur la figure 3 : il a une forme générale parallélépipédique ; on y a ménagé un bec verseur 10. Un trait est tracé sur sa paroi pour indiquer le niveau de remplissage à respecter.In the notched corner 8 of the
Le sachet 4 est illustré plus en détail sur les figures 4 et 5. Il est constitué d'un sac 11 en matière plastique soudé sur une tête de fixation 12. Le sac 11 est formé par soudure de deux feuilles de matière plastique 13 et 14, l'une de ces feuilles 13 étant transparente et l'autre 14 étant opaque. Pour former le sac, les deux feuilles 13 et 14 sont soudées latéralement par les soudures 15 et, pour former le fond, par une soudure transversale 16. Dans la soudure de fond 16, sont scellées deux barrettes 17 en plastique rigide. Comme on peut le voir sur la figure 4, la jonction entre la soudure de fond 16 et les soudures latérales 15 se fait chaque fois en ménageant un angle arrondi 18 ; on évite ainsi, qu'à l'étape de malaxage, de la poudre décolorante reste prisonnière dans les angles. Les deux feuilles plastiques 13 et 14 ont, en partant de la soudure de fond 16, une largeur constante sur une certaine hauteur puis une largeur décroissante en direction de l'embouchure du sac 11 de façon à former en quelque sorte un entonnoir qui favorise l'écoulement du mélange malaxé.The
Le sac 11 est fixé sur la tête de fixation 12, qui est en matière plastique rigide. Ladite tête 12 est obtenue d'une pièce par moulage et se compose de deux éléments coaxiaux 19, 20. Le premier élément 19 est constitué par une jupe ayant en section droite une forme oblongue et dont la surface externe est munie de stries horizontales pour faciliter la fixation du sac 11. Le périmètre de l'élément 19 est voisin du périmètre de l'embouchure du sac 11 de façon à pouvoir enfiler et souder le sac sur l'élément 19 sans faire de plis. L'élément 20 est relié par un épaulement à l'élément 19 ; il constitue un élément annulaire, qui forme un goulot pour le remplissage et le vidage du sachet 4. Ledit élément annulaire 20 est muni d'un filetage externe 21 et d'un filetage interne 22. Le sachet 4 peut être fermé par un capuchon 23, qui est muni d'un filetage interne 24 susceptible de coopérer avec le filetage externe 21 de l'élément annulaire 20.The
Avant la mise en place du sachet 4 dans la coque 2, la poudre décolorante P est introduite dans ledit sachet 4 par l'élément annulaire 20 formant goulot. Après introduction de la poudre P, on presse le sachet 4 entre deux poussoirs pour en expulser l'air et on visse le capuchon 23. On plie ensuite le sachet 4 en deux parties que l'on superpose de façon que les barrettes 17 se trouvent au niveau de l'élément 19 de fixation du sac, tout en maintenant la poudre au voisinage du fond du sac, de façon à préserver de part et d'autre de la pliure une partie vide, la zone où ces deux parties vides sont superposées étant de faible épaisseur. On dispose le sachet ainsi plié dans la coque 2. Le tube 5 contenant le révélateur sous forme de crème est disposé contre le sachet 4, au droit de la zone de faible épaisseur précitée. Dans la coque 2, un pinceau 6 est disposé à côté du tube 5 au niveau de la pliure du sachet 4.Before the
Le tube 5 comporte un goulot 25 (voir figure 6B) muni d'un filetage externe 26 susceptible de coopérer avec le filetage interne 22 de l'élément annulaire 20. Le tube est fermé par un bouchon 27 vissé sur le filetage 26.The tube 5 comprises a neck 25 (see FIG. 6B) provided with an external thread 26 capable of cooperating with the
La disposition relative du sachet 4 sous forme pliée et du tube 5 sur une zone du sachet 4 plié, dans laquelle deux parties vides de poudre se font vis-à-vis, permet d'obtenir un ensemble de conditionnement très compact.The relative arrangement of the
Lorsqu'un utilisateur désire utiliser l'ensemble de conditionnement décrit ci-dessus, il opère de la façon illustrée schématiquement sur les figures 6A à 6E. Il ouvre la coque 2 en enlevant le couvercle 28 et y prélève le sachet 4 contenant la poudre P et le tube 5 contenant le révélateur sous forme de crème C. Il dévisse le capuchon 23 du sachet 4 et le bouchon 27 du tube 5 puis visse le tube 5 dans l'élément annulaire 20, le filetage 26 du goulot 25 du tube 5 coopérant avec le filetage interne 22 de l'élément annulaire 20 (voir figure 6B). Il comprime ensuite le tube 5 pour introduire dans le sachet 4 la totalité de la crème C contenue dans le tube 5. Au cours de cette opération, le tube 5 fermant le sachet 4, la poudre décolorante ne peut pas s'échapper du sachet. L'utilisateur dévisse alors le tube 5 de façon à libérer l'élément annulaire 20 : la poudre décolorante P ne peut s'échapper du sachet 4 puisqu'elle est recouverte par la crème C.When a user wishes to use the packaging assembly described above, he operates in the manner schematically illustrated in FIGS. 6A to 6E. He opens the
L'utilisateur détache ensuite le doseur 7 de la coque 2 et y verse de l'eau (E) jusqu'au niveau déterminé par un trait : il verse cette eau (E) dans le sachet 4 (voir figure 6C). Il revisse ensuite le capuchon 23 sur l'élément annulaire 20 pour fermer le sachet 4 et malaxe le mélange jusqu'à ce qu'il soit homogène, l'homogénéité du mélange pouvant être contrôlée visuellement à travers la face 13 en plastique transparent du sachet 4. Il faut noter que la présence des deux barrettes 17 ne gêne aucunement le malaxage puisque le sachet peut se plier longitudinalement entre les deux barrettes. Pour finir, l'utilisateur dévisse le capuchon 23 et vide le sachet 4 dans la coque 2 qui constitue ainsi une barquette 70 ; le vidage complet du sachet 4 est obtenu en roulant le sac 11 sur les barrettes rigides 17.The user then detaches the
Le mélange obtenu par malaxage peut alors être prélevé dans la barquette 70 à l'aide du pinceau 6 pour être appliqué sur la chevelure.The mixture obtained by kneading can then be taken from the
