Description

La présente invention concerne des sachets à au moins deux compartiments et leurs procédés de fabrication. L'invention concerne plus particulièrement mais non exclusivement les sachets destinés au conditionnement d'une coloration capillaire à utiliser à domicile. The present invention relates to sachets with at least two compartments and methods of making them. The invention relates more particularly, but not exclusively, to sachets intended for conditioning a hair coloring to be used at home.

On assiste en ce moment à l'émergence d'une tendance de fond, démarrant dans les pays émergents, concernant le fait de conditionner de plus en plus de produits dans des sachets. Or, l'évolution de cette tendance est de créer des kits pour lesquels le sur emballage est éliminé pour des raisons de coût et d'écologie, tout élément du kit se trouvant dans des sachets. La demande FR 2 918 038 décrit un sachet à deux compartiments détachables grâce à des prédécoupes. Un tel sachet est de fabrication relativement complexe. La demande EP 1 669 305 Al divulgue un matériau en feuille convenant à la réalisation de sachets contenant une composition de coloration capillaire. At the moment, we are witnessing the emergence of a fundamental trend, starting in emerging countries, concerning the packaging of more and more products in sachets. However, the evolution of this trend is to create kits for which the overpack is eliminated for reasons of cost and ecology, any element of the kit being in bags. The application FR 2 918 038 describes a bag with two compartments detachable through precuts. Such a bag is of relatively complex manufacture. EP 1 669 305 A1 discloses a sheet material suitable for making sachets containing a hair coloring composition.

La demande EP 1 948 529 décrit des sachets à plusieurs compartiments. La demande EP 0 639 364 Al et le brevet US 6 047 817 divulguent des dispositifs de conditionnement à deux compartiments. Néanmoins, les formules voire les objets à mettre en sachet ne sont pas toujours compatibles avec les mêmes matériaux complexes souples, et même temps, on ne 20 peut mettre les différents sachets dans un contenant unique, puisque ce contenant unique doit être éliminé Il existe un besoin pour proposer au consommateur des moyens à bas prix, multi complexes, facile à fabriquer, sans emballages extérieurs, capable de contenir des formules incompatibles avec une seule nature de complexe et/ou des objets. 25 L'invention vise à répondre à ce besoin. L'invention propose un unique sachet composé de plusieurs compartiments, dont au moins deux compartiments sont constitués de matériaux de compositions chimiques différentes. Ce nouveau type de sachet est basé sur le fait qu'il est par exemple possible de 30 souder ensemble plusieurs natures de complexes différents, dans la mesure ou au moins une des couches constituant ces complexes est commune ou soudable à au moins une des couches des autres complexes constituant le sachet. The application EP 1 948 529 describes sachets with several compartments. EP 0 639 364 A1 and US Pat. No. 6,047,817 disclose two-compartment packaging devices. Nevertheless, the formulas or the objects to be bagged are not always compatible with the same flexible complex materials, and at the same time, the different sachets can not be put in a single container, since this single container must be eliminated. need to offer the consumer means at low prices, multi complex, easy to manufacture, without outer packaging, capable of containing formulas incompatible with a single nature of complex and / or objects. The invention aims to meet this need. The invention proposes a single bag composed of several compartments, at least two compartments of which consist of materials of different chemical compositions. This new type of sachet is based on the fact that it is possible, for example, to weld together several types of different complexes, insofar as at least one of the layers constituting these complexes is common or weldable to at least one of the layers of other complexes constituting the bag.

Selon l'un de ses aspects, l'invention a pour objet un sachet à au moins deux compartiments, comportant : - un premier compartiment délimité par deux feuilles en matériaux identiques, un deuxième compartiment délimité par deux feuilles en matériaux identiques, - une ligne de soudure réunissant les premier et deuxième compartiments le long d'une portion au moins de leurs bords, caractérisé par le fait que lesdits matériaux sont de composition chimique différente. According to one of its aspects, the subject of the invention is a sachet with at least two compartments, comprising: a first compartment delimited by two sheets made of identical materials, a second compartment delimited by two sheets made of identical materials, a line weld joining the first and second compartments along at least a portion of their edges, characterized in that said materials are of different chemical composition.

Par « sachet » il faut comprendre une poche souple, avec ou sans la présence d'un organe de distribution tel qu'une capsule, un embout injecté ou une embase comportant un bouchon tel que décrit dans FR 2 921 346 ou FR 2 924 691. Cette embase viendrait par exemple prendre place entre les deux cotés d'un ou de plusieurs compartiment, dans une des lignes de soudures délimitant ce compartiment. By "bag" is meant a flexible bag, with or without the presence of a dispensing member such as a capsule, an injected tip or a base having a plug as described in FR 2 921 346 or FR 2 924 691 This base would for example take place between the two sides of one or more compartments, in one of the weld lines delimiting this compartment.

L'invention permet de réaliser un conditionnement fiable et économique de produits, par exemple une serviette et un produit ou bien une poudre et une huile. Les compartiments sont délimités chacun entièrement ou partiellement par des lignes de soudure. Une ligne de soudure peut souder deux cotés du même compartiment ensemble, ou chacun des cotés de part et d'autre d'une même embase L'invention a encore pour objet, selon un autre de ses aspects, un procédé de fabrication et de remplissage d'un sachet notamment, tel que défini plus haut, comportant les étapes consistant à : - Réaliser au moins deux compartiments ouverts d'extrémité en soudant deux feuilles de dimension différentes, disposées l'une sur l'autre pour former au moins deux compartiments comportant une patte latérale dépassant de la zone de soudure latérale entre les feuilles, ou bien une feuille est repliée sur elle-même, chair contre chair, le long d'une ligne différente de la médiane, de sorte qu'un des cotés dépasse de l'autre. Réaliser éventuellement un ou plusieurs compartiments intermédiaires en soudant deux feuilles de mêmes dimensions, disposées l'une sur l'autre avec un décalage latéral pour former un compartiment comportant une première patte latérale et une deuxième patte latérale dépassant de la zone de soudure latérale entre les feuilles, - Souder les pattes latérales des compartiments d'extrémité, éventuellement intermédiaire(s), entre eux pour former la ou les lignes de soudures, - Remplir les compartiments avec la ou les compositions, - Fermer l'ouverture des compartiments. Ces trois premières étapes ci-dessus peuvent être réalisées selon un processus continu, et ne pas nécessairement être séparées dans le temps. En particulier, on peut amener les différentes feuilles dans leurs positions définitives de manière continue et automatique, et faire les différentes soudures parallèles au sens de défilement avec des têtes de soudure rotatives, puis faire les soudures transversales de façon discontinues. Les sachets intermédiaires ont des parois de même largeur, décalées lors de l'assemblage d'une valeur équivalente à celle du débordement d'une des parois du sachet d'extrémité. La paroi débordante du sachet d'extrémité va être mise en vis-à-vis de la paroi débordante opposée du premier sachet intermédiaire, et la soudure va pouvoir assembler ces deux parois de façon définitive. Alors la seconde paroi du sachet intermédiaire, étant de la même largeur que l'autre, va déborder elle aussi, mais du coté opposé à la première (dessus/dessous). On profite de ce débordement pour y souder la paroi débordante opposée d'un autre sachet intermédiaire et ainsi de suite, jusqu'au dernier sachet d'extrémité, dont les deux bords des parois d'extrémité seront, elles, en vis-à-vis. L'invention concerne aussi un procédé de fabrication et de remplissage d'un sachet tel que défini ci-dessus, comportant les étapes consistant à : - Amener en contact au moins deux feuilles en matériaux présentant une composition chimique différente, Positionner les feuilles pour former au moins deux compartiments d'extrémité comportant une zone latérale dépassant et éventuellement, un ou plusieurs compartiments intermédiaires comportant chacun deux zones latérales dépassant, - Souder simultanément toutes les feuilles, de préférence thermiquement, pour obtenir ledit sachet. The invention makes it possible to produce a reliable and economical packaging of products, for example a towel and a product or a powder and an oil. The compartments are each delimited wholly or partially by welding lines. A weld line can weld two sides of the same compartment together, or each side on both sides of the same base Another object of the invention is, according to another of its aspects, a method of manufacturing and filling of a particular bag, as defined above, comprising the steps of: - Making at least two open end compartments by welding two sheets of different size, arranged one on the other to form at least two compartments having a side tab protruding from the lateral seam area between the sheets, or a sheet is folded over itself, flesh to flesh, along a different line from the median, so that one of the sides protrudes the other. Optionally producing one or more intermediate compartments by welding two sheets of the same dimensions, arranged one over the other with a lateral offset to form a compartment having a first side leg and a second side tab protruding from the lateral welding zone between the sheets, - Weld the lateral tabs of the end compartments, possibly intermediate (s), between them to form the weld line (s), - Fill the compartments with the composition (s), - Close the opening of the compartments. These first three steps above can be performed in a continuous process, and not necessarily be separated in time. In particular, it is possible to bring the various sheets into their definitive positions in a continuous and automatic manner, and to make the different welds parallel to the direction of travel with rotating welding heads, then to make the transverse welds in a discontinuous manner. The intermediate bags have walls of the same width, offset during assembly by a value equivalent to that of the overflow of one of the walls of the end bag. The protruding wall of the end bag will be placed opposite the opposite projecting wall of the first intermediate bag, and the weld will be able to assemble these two walls definitively. Then the second wall of the intermediate bag, being of the same width as the other, will overflow too, but the opposite side to the first (above / below). We take advantage of this overflow to weld the opposing overflowing wall of another intermediate bag and so on, to the last end bag, the two edges of the end walls will be vis-à-vis screw. The invention also relates to a method of manufacturing and filling a bag as defined above, comprising the steps of: - bringing into contact at least two sheets of materials having a different chemical composition, positioning the sheets to form at least two end compartments having a protruding lateral zone and optionally one or more intermediate compartments each having two lateral zones protruding, - simultaneously welding all the sheets, preferably thermally, to obtain said sachet.

L'invention a encore pour objet, selon un autre de ses aspects, un procédé cosmétique comportant l'application sur les cheveux ou la peau du contenu d'au moins un compartiment d'un sachet. L'invention a encore pour objet, selon un autre de ses aspects, l'utilisation d'un sachet selon l'invention, tel que défini plus haut, pour le conditionnement d'un produit de coloration permanente, semi-permanente ou temporaire. Avantageusement, la ligne de soudure comporte au moins une zone reliant la feuille du premier compartiment et la feuille du deuxième compartiment. De cette façon, la séparation est adaptée aux produits conditionnés. The invention further relates, in another of its aspects, a cosmetic process comprising the application to the hair or the skin of the contents of at least one compartment of a bag. The invention further relates, in another of its aspects, to the use of a sachet according to the invention, as defined above, for the packaging of a permanent, semi-permanent or temporary coloring product. Advantageously, the weld line comprises at least one zone connecting the sheet of the first compartment and the sheet of the second compartment. In this way, the separation is adapted to the packaged products.

Plus avantageusement, une feuille s'étend dans le prolongement de l'autre feuille sur une portion au moins d'un bord. Ainsi, la soudure est visible et facilement repérable. Par exemple, le sachet comporte au moins trois compartiments, les compartiments intermédiaires comportant deux feuilles et de même dimension. Par exemple, le sachet comporte deux compositions à mélanger et un outil. More preferably, one sheet extends in the extension of the other sheet over at least one portion of an edge. Thus, the weld is visible and easily identifiable. For example, the bag has at least three compartments, the intermediate compartments having two sheets and the same size. For example, the bag has two compositions to mix and a tool.

Préférentiellement, les compartiments d'extrémité comportent des feuilles et de dimensions différentes. Ainsi, les compartiments d'extrémité peuvent s'aplatir facilement sans se déchirer. Selon un mode de réalisation préféré, la contenance des compartiments allant de 0,1 à 1500 ml, de préférence allant de 0,2 à 100 ml. Ces volumes conviennent bien à un 20 mono-usage. Très avantageusement, les compartiments sont délimités chacun entièrement par des lignes de soudure. Cette présentation procure un avantage visuel et technique. L'un des compartiments peut contenir une composition tinctoriale pour la coloration des cheveux. EN général, il peut s'agir d'un produit pour la coloration 25 permanente (coloration d'oxydation), ou un produit pour la coloration semi-permanente ou temporaire (coloration directe). Des exemples de tels produits sont donnés dans le livre « Chemical and Physical Behavior of Human Hair », 4ème édition, chapitre 6, pages 311 à 344 de Clarence R. Robbins paru aux éditions Springer. En particulier, la composition tinctoriale contenue dans le sachet peut contenir 30 une ou plusieurs bases d'oxydation et/ou un ou plusieurs coupleurs conventionnellement utilisés pour la teinture de fibres kératiniques. Preferably, the end compartments comprise sheets and of different dimensions. Thus, the end compartments can flatten easily without tearing. According to a preferred embodiment, the capacity of the compartments ranging from 0.1 to 1500 ml, preferably ranging from 0.2 to 100 ml. These volumes are well suited for a single use. Very advantageously, the compartments are each delimited by solder lines. This presentation provides a visual and technical advantage. One of the compartments may contain a dye composition for coloring the hair. In general, it may be a product for permanent coloring (oxidation dye), or a product for semi-permanent or temporary coloring (direct dyeing). Examples of such products are given in Clarence R. Robbins' book "Chemical and Physical Behavior of Human Hair", 4th Edition, Chapter 6, pages 311-344. In particular, the dyeing composition contained in the sachet may contain one or more oxidation bases and / or one or more couplers conventionally used for dyeing keratinous fibers.

Parmi les bases d'oxydation, on peut citer les para-phénylènediamines, les bis-phénylalkylènediamines, les para-aminophénols, les bis-para-aminophénols, les ortho-aminophénols, les bases hétérocycliques et leurs sels d'addition. Parmi les coupleurs, on peut notamment citer les méta-phénylènediamines, les méta-aminophénols, les méta-diphénols, les coupleurs naphtaléniques, les coupleurs hétérocycliques et leur sels d'addition. La composition tinctoriale peut également comprendre un agent oxydant qui peut être choisi parmi le peroxyde d'hydrogène, le peroxyde d'urée, les bromates de métaux alcalins, les persels tels que les perborates et les persulfates, ainsi que les enzymes parmi lesquelles on peut citer les peroxydases, les oxydoréductases à 2 électrons tels que les uricases et les oxygénases à 4 électrons comme les laccases. L'utilisation du peroxyde d'hydrogène est particulièrement préférée. La composition tinctoriale peut en outre contenir des colorants directs additionnels. De tels colorants peuvent être utilisés seuls ou en combinaison avec une composition tinctoriale telle que précédemment décrite. Ces colorants directs sont par exemple choisis parmi les colorants directs nitrés benzéniques neutres, acides ou cationiques, les colorants directs azoïques neutres, acides ou cationiques, les colorants tétraazapentaméthiniques, les colorants quinoniques et en particulier anthraquinoniques neutres, acides ou cationiques, les colorants directs aziniques, les colorants directs triarylméthaniques, les colorants directs indoaminiques et les colorants directs naturels. Parmi les colorants directs naturels, on peut citer la lawsone, la juglone, l'alizarine, la purpurine, l'acide carminique, l'acide kermésique, la purpurogalline, le protocatéchaldéhyde, l'indigo, l'isatine, la curcumine, la spinulosine, l'apigénidine. On peut également utiliser les extraits ou décoctions contenant ces colorants naturels et notamment les cataplasmes ou extraits à base de henné. Des agents bénéfiques pour les matières kératiniques, ou solution nutritive, peuvent également être ajoutés à de telles compositions. L'invention sera mieux comprise à la lecture de la description qui suit et à l'examen des figures qui l'accompagnent. Celles ci ne sont présentées qu'à titre indicatif et nullement limitatif de l'invention. Les figures montrent : Figure 1: Vue en perspective d'un sachet selon l'invention, Figure 2: Vue de dessus d'une soudure entre deux compartiments du sachet selon la figure 1, Sur la figure 1, le sachet selon l'invention comporte trois compartiments 5, 7 et 9. Les compartiments 5 et 9 forment des compartiments d'extrémité. Le compartiment 7 forme un compartiment intermédiaire. Le premier compartiment 5 s'étend selon un axe X, qui est l'axe longitudinal pour ce compartiment, sur une longueur (1). Il s'étend sur une largeur (L) définie selon l'axe Y. Ce compartiment est fermé par des soudures à ses deux extrémités latérales parallèles à l'axe X ainsi qu'à une extrémité longitudinale définissant un fond. L'autre extrémité longitudinale est ouverte. Avantageusement, la longueur (1) du compartiment est comprise entre 5 et 20 cm, de préférence entre 8 et 15 cm. Avantageusement, la largueur (L) du compartiment est comprise entre 3 cm et 10 cm, de préférence entre 5 cm et 8 cm. La largeur (L) est pratiquement constante. Elle peut diminuer vers une extrémité supérieure pour définir par exemple un col qui sert à la distribution du contenu de ce compartiment, ce col pouvant être ouvert par découpe du sachet selon une ligne de déchirure transversale. La contenance du premier compartiment 5 est par exemple de 100 ml. Le compartiment 5 représenté sur la figure 1 présente une forme générale allongée selon l'axe longitudinal X. Il présente une largeur sensiblement constante mais il pourrait en être autrement sans que l'on sorte du cadre de la présente invention. Le compartiment 5 pourrait, par exemple, présenter une forme trapézoïdale ou ovale. Les feuilles 2a et 2b sont soudées entre elles le long des côtés du sachet entre les portions 21a et 21b d'un côté et 22a et 22b de l'autre côté. Elles peuvent aussi être soudées sur le fond du sachet. Conformément à l'invention, la feuille 2a dépasse d'un seul côté du sachet 5 de la zone de soudure entre les portions 22a et 22b. Avantageusement, la feuille 2a dépasse de cette zone de soudure sur tout le côté du sachet, sur une portion 122a Plus avantageusement encore, la feuille 2a dépasse de la zone de soudure entre les portions 22a et 22b d'une distance égale et de préférence égale à la largeur de la zone de soudure entre les portions 22a et 22b mesurée selon l'axe Y. Among the oxidation bases that may be mentioned are para-phenylenediamines, bis-phenylalkylenediamines, para-aminophenols, bis-para-aminophenols, ortho-aminophenols, heterocyclic bases and their addition salts. Among the couplers, there may be mentioned meta-phenylenediamines, meta-aminophenols, meta-diphenols, naphthalenic couplers, heterocyclic couplers and their addition salts. The dye composition may also comprise an oxidizing agent which may be chosen from hydrogen peroxide, urea peroxide, alkali metal bromates, persalts such as perborates and persulfates, as well as the enzymes from which mention peroxidases, 2-electron oxidoreductases such as uricases and 4-electron oxygenases such as laccases. The use of hydrogen peroxide is particularly preferred. The dye composition may further contain additional direct dyes. Such dyes may be used alone or in combination with a dyeing composition as previously described. These direct dyes are, for example, chosen from neutral, acidic or cationic nitro-benzene direct dyes, neutral azo, acid or cationic direct dyes, tetraazapentamethine dyes, neutral or acidic or cationic quinone dyes, in particular neutral anthraquinone dyes and direct azine dyes. , triarylmethane direct dyes, indoamine direct dyes and natural direct dyes. Among the natural direct dyes that may be mentioned are lawsone, juglone, alizarin, purpurin, carminic acid, kermesic acid, purpurogalline, protocatechaldehyde, indigo, isatin, curcumin, spinulosin, apigenidine. It is also possible to use the extracts or decoctions containing these natural dyes, and in particular poultices or extracts made from henna. Agents beneficial to keratin materials, or nutrient solution, can also be added to such compositions. The invention will be better understood on reading the description which follows and on examining the figures which accompany it. These are presented only as an indication and in no way limitative of the invention. The figures show: Figure 1: Perspective view of a bag according to the invention, Figure 2: Top view of a weld between two compartments of the bag according to Figure 1, In Figure 1, the bag according to the invention has compartments 5, 7 and 9. Compartments 5 and 9 form end compartments. The compartment 7 forms an intermediate compartment. The first compartment 5 extends along an axis X, which is the longitudinal axis for this compartment, over a length (1). It extends over a width (L) defined along the Y axis. This compartment is closed by welds at its two lateral ends parallel to the X axis and at a longitudinal end defining a bottom. The other longitudinal end is open. Advantageously, the length (1) of the compartment is between 5 and 20 cm, preferably between 8 and 15 cm. Advantageously, the width (L) of the compartment is between 3 cm and 10 cm, preferably between 5 cm and 8 cm. The width (L) is practically constant. It can decrease towards an upper end to define for example a neck which serves for the distribution of the contents of this compartment, this neck can be opened by cutting the bag according to a transverse tear line. The capacity of the first compartment 5 is for example 100 ml. The compartment 5 shown in Figure 1 has a generally elongated shape along the longitudinal axis X. It has a substantially constant width but it could be otherwise without departing from the scope of the present invention. The compartment 5 could, for example, have a trapezoidal or oval shape. The sheets 2a and 2b are welded together along the sides of the bag between the portions 21a and 21b on one side and 22a and 22b on the other side. They can also be welded to the bottom of the bag. According to the invention, the sheet 2a protrudes from one side of the bag 5 of the weld zone between the portions 22a and 22b. Advantageously, the sheet 2a protrudes from this weld zone over the entire side of the bag, on a portion 122a. More advantageously, the sheet 2a protrudes from the weld zone between the portions 22a and 22b by an equal and preferably equal distance. to the width of the weld zone between the portions 22a and 22b measured along the Y axis.

En général, la largeur des zones de soudure entre les feuilles 2a et 2b est identiques sur les deux bords latéraux du compartiment, c'est-à-dire entre les portions 21a et 21b d'un côté et 22a et 22b de l'autre. Le premier compartiment 5 est configuré pour contenir un premier produit. In general, the width of the weld zones between the sheets 2a and 2b is identical on the two lateral edges of the compartment, that is to say between the portions 21a and 21b on one side and 22a and 22b on the other. . The first compartment 5 is configured to contain a first product.

Le second compartiment d'extrémité 9 est de préférence réalisé de manière identique au premier compartiment, néanmoins il peut présenter une section différente de celle du premier compartiment 5. Le second compartiment d'extrémité 9 est configuré pour contenir un second produit. Le compartiment 9 est formé par la superposition de deux feuilles 4a et 4b. Ces feuilles sont soudées entre elles le long des côtés du sachet entre les portions 41a et 41b d'un côté et 42a et 42b de l'autre côté. Elles peuvent aussi être soudées sur le fond du sachet. Conformément à l'invention, la feuille 4b dépasse avantageusement d'un seul côté du sachet 9 de la zone de soudure entre les portions 41a et 41b. Avantageusement, la feuille 4b dépasse de cette zone de soudure sur tout le côté du sachet, sur une portion 141b. Le compartiment intermédiaire 7 est délimité par une paroi supérieure 3a et une paroi inférieure 3b reliées entre elles par deux soudures formées au niveau de leurs bords périphériques respectifs3 la et 31b d'un côté et 32a et 32b de l'autre. Les deux parois 3a et 3b sont de préférence de section sensiblement identique. L'une au moins des parois peut être bombée, voire comporter un soufflet, de manière à conférer un volume de l'ordre de quelques millimètres cube supplémentaires. Conformément à l'invention, la feuille 3a dépasse d'un premier côté du compartiment 7 de la zone de soudure entre les portions 32a et 32b. La partie débordante forme la zone 132a de ce premier côté du compartiment 7. La feuille 3b dépasse de l'autre côté du sachet 7 de la zone de soudure entre les portions 31a et 31b. La partie débordante forme la zone 131b du deuxième côté du compartiment 7. Le compartiment 7 est relié : - au compartiment 5 par une ligne de soudure entre les portions 122a de la feuille 2a et 131b de la feuille 3b, - au compartiment 9 par une ligne de soudure entre les portions 132a de la feuille 3a et 141b de la feuille 4b. The second end compartment 9 is preferably identical to the first compartment, however it may have a different section than the first compartment 5. The second end compartment 9 is configured to contain a second product. The compartment 9 is formed by the superposition of two sheets 4a and 4b. These sheets are welded together along the sides of the bag between the portions 41a and 41b on one side and 42a and 42b on the other side. They can also be welded to the bottom of the bag. According to the invention, the sheet 4b advantageously extends on one side of the bag 9 of the weld zone between the portions 41a and 41b. Advantageously, the sheet 4b protrudes from this weld zone over the entire side of the bag, on a portion 141b. The intermediate compartment 7 is delimited by an upper wall 3a and a lower wall 3b interconnected by two welds formed at their respective peripheral edges 3a and 31b on one side and 32a and 32b on the other. The two walls 3a and 3b are preferably of substantially identical section. At least one of the walls may be curved, or even include a bellows, so as to confer a volume of the order of a few cubic millimeters additional. According to the invention, the sheet 3a protrudes from a first side of the compartment 7 of the weld zone between the portions 32a and 32b. The protruding portion forms the zone 132a of this first side of the compartment 7. The sheet 3b protrudes from the other side of the bag 7 of the weld zone between the portions 31a and 31b. The protruding portion forms the zone 131b of the second side of the compartment 7. The compartment 7 is connected: - to the compartment 5 by a weld line between the portions 122a of the sheet 2a and 131b of the sheet 3b, - the compartment 9 by a welding line between the portions 132a of the sheet 3a and 141b of the sheet 4b.

Les deux feuilles délimitant chaque compartiment 5, 7 et 9 sont de préférence formées à partir d'au moins une feuille en matériau aluminium et ou en matériau thermoplastique tel que des matériaux polyoléfiniques comme le polyéthylène (PE) ou le polypropylène (PP), ou encore en polyéthylène téréphtalate (PET), éthylène vinyle 5 hydroxyde (EVOH), éthylène vinyle acétate (EVA), polychlorure de vinyle (PVC) ou en polyamide (PA). Elles sont par exemple stratifiées en plusieurs couches, par exemple en une succession de couches de respectivement PE, EVOH et PE aux fonctions d'isolation et d'imperméabilité différentes. De telles feuilles peuvent notamment être assemblées entre elles par thermosoudure. 10 Plus avantageusement encore, les deux feuilles délimitant chaque compartiment 5, 7 et 9 sont réalisées en matériaux identiques. Ainsi, chaque compartiment peut avoir une structure et une nature différente les un des autres, on peut par exemple avoir un sachet de structure PET/PE, destiné à contenir un objet, gants, notice, un sachet de structure PPET/colle/Alu/EAA/PE destiné à contenir un 15 colorant pour cheveux, un sachet de structure PET/Colle/Alu/PE destiné à contenir une solution oxydante. Les sachets peuvent être opaques ou transparents, de taille différentes les un des autres, que ce soit en largeur ou en longueur. La figure 2 montre une vue de dessus de la zone de jonction entre les compartiments 5 et 7. Cette zone peut être divisée en trois parties : 20 une partie où se superposent les feuilles 2a et 2b, une partie où se superposent les feuilles 2a et 3b, une partie où se superposent les feuilles 3a et 3b. Chaque feuille présente de préférence une épaisseur inférieure ou égale à 250 gm. Par exemple, pour le compartiment 5, les deux feuilles 2 et 3 du matériau 25 multicouche sont disposées en regard l'une de l'autre, partie soudable contre partie soudable, et soudées ensemble par soudure thermique de manière à fermer le sachet en laissant une partie ouverte. Par cette partie ouverte, on insère par exemple une canne d'un dispositif de remplissage de la composition et l'on injecte celle-ci. 30 Après retrait du dispositif de remplissage, une soudure thermique vient fermer le sachet de façon complètement étanche, tout en lui donnant la forme définitive désirée. Le compartiment 7 est réalisé de la même façon. The two sheets delimiting each compartment 5, 7 and 9 are preferably formed from at least one sheet of aluminum material and or thermoplastic material such as polyolefinic materials such as polyethylene (PE) or polypropylene (PP), or polyethylene terephthalate (PET), ethylene vinyl hydroxide (EVOH), ethylene vinyl acetate (EVA), polyvinyl chloride (PVC) or polyamide (PA). For example, they are laminated in several layers, for example in a succession of layers of respectively PE, EVOH and PE with different insulation and impermeability functions. Such sheets may in particular be assembled together by heat sealing. More preferably, the two sheets delimiting each compartment 5, 7 and 9 are made of identical materials. Thus, each compartment can have a structure and a different nature from one another, one can for example have a PET / PE structure bag, intended to contain an object, gloves, instructions, a bag structure PPET / glue / Alu / EAA / PE for containing a hair dye, a PET / Glue / Alu / PE structure bag for containing an oxidizing solution. The bags may be opaque or transparent, of different sizes from one another, whether in width or length. FIG. 2 shows a view from above of the junction zone between the compartments 5 and 7. This zone can be divided into three parts: a part where the sheets 2a and 2b are superimposed, a part where the sheets 2a are superposed and 3b, a part where the sheets 3a and 3b are superimposed. Each sheet preferably has a thickness of less than or equal to 250 gm. For example, for the compartment 5, the two sheets 2 and 3 of the multilayer material 25 are arranged facing each other, part weldable against weldable part, and welded together by thermal welding so as to close the bag leaving an open party. For this open part, for example, a cane of a device for filling the composition is inserted and the latter is injected. After removal of the filling device, a heat seal closes the bag completely sealed, while giving it the desired final shape. The compartment 7 is made in the same way.

On procède alors à une soudure supplémentaire pour relier les deux compartiments 5 et 7. Cette soudure supplémentaire est du type de celles qui permettent de souder au travers d'une composition sans détériorer celle-ci, de préférence une soudure par ultrasons. Cette soudure est aussi une soudure thermique, car il n'y a pas de formule à l'endroit ou les feuilles des deux compartiments adjacents doivent être soudées ensemble. Les deux étapes de fabrication sont effectuées l'une après l'autre, sans rupture de la chaîne de production. Puis, on soude de la même façon le compartiment 9. Selon l'invention, toutes les feuilles des différents matériaux aussi peuvent être amenées ensemble, déjà positionnées comme sera leur position respective dans le sachet final. Puis, elles sont soudées. L'invention n'est pas limitée à l'exemple qui vient d'être décrit. Un sachet selon l'invention permet d'offrir une sécurité à l'utilisateur, présente une empreinte carbone inférieure à celle d'un tube en aluminium tel qu'utilisé actuellement, est d'un coût de revient inférieur à un tel tube et à des sachets individuels et est beaucoup plus simple à réaliser industriellement. De manière connue, on peut réaliser sur les sachets des entailles ou des lignes de déchirure, par exemple qui s'étendent obliquement relativement à l'axe longitudinal X. L'expression « comportant un » doit être comprise comme étant synonyme de « comportant au moins un », sauf si le contraire est spécifié.20 An additional weld is then used to connect the two compartments 5 and 7. This additional weld is of the type which makes it possible to weld through a composition without damaging it, preferably an ultrasonic weld. This weld is also a heat weld because there is no formula where the leaves of the two adjacent compartments must be welded together. The two manufacturing steps are carried out one after the other, without breaking the production line. Then, the compartment 9 is welded in the same way. According to the invention, all the sheets of the different materials can also be brought together, already positioned as will be their respective position in the final bag. Then, they are welded. The invention is not limited to the example which has just been described. A pouch according to the invention makes it possible to offer safety to the user, has a carbon footprint lower than that of an aluminum tube as currently used, is of a lower cost price than such a tube and individual bags and is much simpler to produce industrially. In a known manner, it is possible to make notches or tear lines on the bags, for example which extend obliquely with respect to the longitudinal axis X. The expression "comprising a" must be understood as being synonymous with "comprising at least one minus one "unless otherwise specified.20
