Description

La présente invention concerne le conditionnement d'un produit de consistance crémeuse à pâteuse, notamment un produit cosmétique tel qu'un fond de teint.The present invention relates to the packaging of a consistency product creamy to pasty, especially a cosmetic product such as a foundation.

On connaít des compositions pâteuses utilisées pour le maquillage, nécessitant pour leur extrusion, du fait de leur viscosité élevée, des filières de diamètre important.We know pasty compositions used for makeup, requiring for their extrusion, due to their high viscosity, large diameter dies.

Il est connu de conditionner ces compositions pâteuses dans des pots ou renfoncements d'un boítier, l'ouverture d'introduction du produit étant suffisamment grande pour permettre le remplissage à cadence élevée par la filière d'extrusion.It is known to package these pasty compositions in pots or recesses in a housing, the opening for introducing the product being sufficient large to allow filling at high speed through the extrusion die.

On connaít par le modèle d'utilité allemand DE-U-295 02 988 un applicateur en forme de gant de toilette, comportant une enveloppe renfermant une crème solaire ou une huile et, séparée de l'enveloppe par une feuille imperméable, une poche pour recevoir la main de l'utilisateur. Le produit est contenu dans un matériau formant réservoir, présent entre deux feuilles de l'enveloppe.We know by the German utility model DE-U-295 02 988 an applicator in the form of a washcloth, comprising an envelope containing a sunscreen or an oil and, separated from the envelope by a waterproof sheet, a pocket for receive the user's hand. The product is contained in a forming material tank, present between two sheets of the envelope.

L'enveloppe est réalisée dans un matériau choisi de telle sorte que le produit ne la traverse que si le contenu de l'enveloppe est mis sous pression au moment de l'application.The envelope is made of a material chosen so that the product does not the cross member only if the contents of the envelope are pressurized at the time of the application.

La feuille imperméable vise à éviter le contact des doigts de l'utilisateur avec le produit.The waterproof sheet aims to avoid contact of the user's fingers with the product.

Un tel applicateur convient pour l'application d'une crème solaire ou d'une pommade sur le corps mais n'est pas adapté au prélèvement d'un produit pâteux tel qu'un fond de teint, au moyen d'un doigt ou d'un applicateur.Such an applicator is suitable for applying a sunscreen or a ointment on the body but is not suitable for taking a pasty product such than a foundation, using a finger or an applicator.

On connaít par le brevet US 3,246,444 un procédé de fabrication d'une poche contenant un produit pouvant être versé, par exemple du sucre.We know from US Patent 3,246,444 a method of manufacturing a pocket containing a pourable product, for example sugar.

Dans ce procédé, la poche est remplie d'une certaine quantité de produit puis le haut de la poche est scellé au-dessus du niveau du produit.In this process, the bag is filled with a certain amount of product and then the top of the pocket is sealed above the level of the product.

On connaít par la demande de brevet britannique GB-A-2 217 299 un boítier agencé pour recevoir des blocs de produits cosmétiques ou des godets contenant des produits cosmétiques.We know from British patent application GB-A-2 217 299 a housing arranged to receive cosmetic blocks or buckets containing cosmetic products.

L'invention a pour objet une poche de conditionnement d'un produit de consistance crémeuse à pâteuse qui présente les caractéristiques énoncées dans la revendication 1. The subject of the invention is a pouch for packaging a product of creamy to pasty consistency that has the characteristics set out in the claim 1.

La perméabilité au produit de la feuille avant, au travers de laquelle s'effectue la distribution du produit, peut être obtenue grâce à des perforations multiples de la feuille ou par la réalisation de cette feuille en un matériau poreux tissé ou non tissé ou spongieux ou fritté.The permeability to the product of the front sheet, through which takes place product distribution, can be achieved through multiple perforations of the sheet or by making this sheet of porous woven or non-woven material or spongy or sintered.

Il est encore possible de réaliser ladite zone perméable en superposant un film perforé et un film en un matériau poreux tissé ou non tissé ou spongieux ou fritté. It is still possible to produce said permeable zone by superimposing a film perforated and a film of porous woven or non-woven or spongy or sintered material.

L'utilisateur peut prélever le produit contenu dans la poche en passant son doigt sur la feuille avant, ou au moyen d'un applicateur.The user can take the product from the pocket by running his finger over the front sheet, or by means of a applicator.

La feuille avant étant réalisée dans un matériau souple, elle confère à l'utilisateur une impression de douceur au toucher.The front sheet being made of a flexible material, it gives the user an impression of softness to the touch.

En outre, l'utilisateur peut en pressant la feuille avant contre la feuille arrière, laquelle est rigide, semi-rigide ou souple mais repose alors sur une surface rigide, prélever juste la quantité de produit nécessaire, ce qui n'est pas toujours le cas lors du conditionnement du produit dans un pot et que le produit est soit très adhérent soit faiblement adhérent.In addition, the user can by pressing the sheet before against the backsheet, which is rigid, semi-rigid or flexible but then rests on a rigid surface, just take the amount of product required, which is not always the case when packaging of the product in a jar and that the product is either very adherent or weakly adherent.

En effet, dans le premier cas, le produit tend à adhérer en bloc au doigt de l'utilisateur qui veut le prélever de sorte qu'il est difficile d'extraire du pot une faible quantité de produit seulement.Indeed, in the first case, the product tends to adhere in block to the finger of the user who wants to take it so that it it is difficult to extract a small amount of product from the jar only.

Lorsqu'au contraire le produit est faiblement adhérent et a tendance à former des agglomérats sans coller au doigt de l'utilisateur, il est difficile de prélever proprement du produit.When, on the contrary, the product is weakly adherent and has tendency to form agglomerates without sticking to the finger it is difficult for the user to collect the product properly.

Grâce à l'invention, il est possible de conditionner un produit de consistance crémeuse à pâteuse, très adhérent ou faiblement adhérent, sans rencontrer les inconvénients du conditionnement en pot.Thanks to the invention, it is possible to condition a creamy to pasty consistency, very sticky or weakly adherent, without encountering the disadvantages of packaging in jar.

Ainsi, l'invention offre la possibilité de conditionner une très large gamme de produits.Thus, the invention offers the possibility of conditioning a very wide range of products.

Dans une réalisation particulière de l'invention, les feuilles avant et arrière sont sensiblement planes et assemblées l'une sur l'autre de manière à ce qu'après le vidage complet de la poche, cette dernière soit plane et lesdites feuilles soient au contact l'une avec l'autre sur une majeure partie de leur surface.In a particular embodiment of the invention, the sheets front and rear are substantially flat and assembled one on the other so that after the complete emptying of the bag, this last is flat and said sheets are in contact with one the other over most of their surface.

Avantageusement, on recouvre la feuille perméable au produit d'une pellicule pelable amovible pour empêcher la sortie du produit et garantir la conservation de ce dernier à l'abri de l'air jusqu'à la première utilisation.Advantageously, the sheet permeable to the product is covered removable peel-off film to prevent product from coming out and guarantee the conservation of the latter sheltered from air until the first use.

Dans une réalisation particulière de l'invention, la feuille avant, perméable au produit, est recouverte d'un cache ajouré en son centre.In a particular embodiment of the invention, the sheet front, permeable to the product, is covered with an openwork cover in center.

Avantageusement, ce cache est constitué par un cadre rigide. Advantageously, this cover is constituted by a rigid frame.

La poche peut avantageusement être utilisée comme recharge dans un boítier pour le maquillage.The pouch can advantageously be used as a refill in a case for makeup.

L'invention a ainsi également pour objet un boítier pour le maquillage, comportant un réceptacle présentant un fond, et logeant une poche telle que précitée, la feuille arrière reposant sur ledit fond.The invention therefore also relates to a housing for the makeup, comprising a receptacle having a bottom, and accommodating a pocket as mentioned above, the back sheet resting on said background.

Selon une réalisation particulière dudit boítier, le fond dudit réceptacle est rigide et la feuille arrière de la poche est souple et repose sur ledit fond.According to a particular embodiment of said housing, the bottom of said receptacle is rigid and the back sheet of the pocket is flexible and rests on said bottom.

Selon une autre réalisation particulière dudit boítier, ledit réceptacle est constitué par un tiroir permettant, lorsqu'il est extrait du boítier, l'introduction ou le remplacement de la poche.According to another particular embodiment of said housing, said receptacle is constituted by a drawer allowing, when it is extract from the case, introduction or replacement of the pocket.

L'invention a encore pour objet un procédé selon la revendication 18.The invention also relates to a method according to claim 18.

Avantageusement, la masse de produit est étalée en pressant les feuilles l'une contre l'autre.Advantageously, the mass of product is spread by pressing the leaves against each other.

Dans un mode de mise en oeuvre particulier, la poche comporte une feuille qui est perforée au moins dans sa région centrale et recouverte sur sa région perforée d'une pellicule amovible.In a particular embodiment, the pocket comprises a sheet which is perforated at least in its central region and covered on its perforated region with a removable film.

La masse de produit peut être déposée sur l'une des feuilles puis recouverte par l'autre feuille.The mass of product can be deposited on one of the sheets then covered with the other sheet.

En variante, les deux feuilles sont préassemblées pour former un fourreau, permettant l'introduction d'un bec de remplissage en produit de grand diamètre.Alternatively, the two sheets are pre-assembled for form a sheath, allowing the introduction of a filling spout in large diameter product.

Avantageusement, les feuilles sont préassemblées de manière à former un entonnoir à l'extérieur dudit fourreau, facilitant l'introduction dudit bec de remplissage. Advantageously, the sheets are pre-assembled so to form a funnel outside of said sheath, facilitating the introduction of said filling spout.

Après le remplissage du fourreau, le côté d'introduction du bec de remplissage est fermé et l'entonnoir est détaché par découpe pour former ladite poche.After filling the sleeve, the insertion side of the filling spout is closed and the funnel is cut out to form said pocket.

On a représenté sur la figure 1 une poche de conditionnement 1 conforme à un premier exemple de réalisation de l'invention.There is shown in Figure 1 a packaging bag 1 in accordance with a first embodiment of the invention.

Cette poche 1 présente dans l'exemple décrit un contour rectangulaire et des faces supérieure et inférieure généralement convexes vers l'extérieur.This pocket 1 present in the example describes a contour rectangular and upper and lower faces generally convex outwards.

La poche 1 est formée dans l'exemple décrit par l'assemblage de deux feuilles 2,3 indépendantes, souples, selon une ligne de scellage S s'étendant le long du bord des quatre côtés de la poche sur une largeur e.The pocket 1 is formed in the example described by the assembly of two independent sheets 2,3, flexible, according to a line of S seal extending along the edge of all four sides of the pocket over a width e.

La feuille supérieure 3, qui est destinée à faire face à l'utilisateur pendant l'usage de la poche, est appelée feuille avant dans la suite, et la feuille inférieure 2, qui repose sur une surface plane ou légèrement courbe lors de l'utilisation, est appelée feuille arrière.The top sheet 3, which is intended to face the user while using the pocket, is called the front sheet below, and the lower sheet 2, which rests on a surface flat or slightly curved when in use, is called sheet back.

En variante, la poche peut être formée à partir d'une bande souple pliée sur elle-même, auquel cas les deux feuilles sont liées entre elles par un côté avant d'être assemblées le long des trois côtés restants.Alternatively, the pocket can be formed from a strip flexible folded on itself, in which case the two sheets are linked between them by one side before being assembled along the three remaining sides.

Dans une variante encore, la poche peut être formée par l'assemblage d'une feuille souple sur une feuille relativement rigide, telle qu'une feuille de carton plastifiée ou une plaque mince en matière plastique rigide.In another variant, the pocket can be formed by assembling a flexible sheet on a relatively sheet rigid, such as a sheet of laminated cardboard or a thin plate made of rigid plastic.

La poche 1 contient une masse d'un produit de consistance crémeuse à pâteuse 4 et la feuille avant 3 présente une région centrale perméable à ce produit.Bag 1 contains a mass of a consistency product creamy to pasty 4 and the front leaf 3 has a region central permeable to this product.

Avantageusement, la feuille avant 3 au moins est transparente pour permettre à l'utilisateur de voir le produit contenu à l'intérieur de la poche.Advantageously, the front sheet 3 at least is transparent to allow the user to see the product contained at inside the pocket.

Dans l'exemple décrit, la feuille avant 3 est perforée dans sa région centrale à la manière d'un tamis pour permettre la distribution du produit au travers de multiples perforations 6 de petit diamètre. Jusqu'à la première utilisation, cette région perforée est recouverte extérieurement d'une pellicule d'obturation amovible 5, constituée par exemple par un film adhésif. In the example described, the front sheet 3 is perforated in its central region like a sieve to allow distribution of the product through multiple perforations 6 of small diameter. Until the first use, this region perforated is covered externally with a sealing film removable 5, constituted for example by an adhesive film.

La feuille avant 3 peut être perforée sur la totalité de sa surface ou seulement dans sa région centrale.The front sheet 3 can be perforated over all of its surface or only in its central region.

Avantageusement, on peut rapporter sur la feuille avant 3 un cache ajouré en son centre, destiné à masquer la zone d'assemblage des feuilles 2 et 3, pouvant également servir à délimiter précisément la zone de distribution du produit et à supporter la pellicule amovible 5.Advantageously, one can report on the sheet before 3 a openwork cover in its center, intended to hide the assembly area sheets 2 and 3, which can also be used to delimit precisely the product distribution area and to support the film removable 5.

Un tel cache peut être réalisé sous la forme d'un cadre relativement rigide comme cela sera décrit dans la suite.Such a cover can be made in the form of a frame relatively rigid as will be described below.

La souplesse de la feuille avant 3 permet d'assurer le vidage complet de la poche de conditionnement au travers des perforations de la feuille avant 3 lorsque les feuilles 2,3 sont pressées l'une contre l'autre, la feuille arrière 2 reposant si elle est souple sur une surface rigide telle que le fond d'un réceptacle, comme cela sera précisé dans la suite.The flexibility of the front sheet 3 ensures emptying complete of the packaging pouch through the perforations of the front sheet 3 when the sheets 2,3 are pressed one against the other, the back sheet 2 resting if it is flexible on a rigid surface such as the bottom of a receptacle, as will be specified below.

La feuille 3 peut avantageusement être conformée de manière à prendre au repos une forme légèrement bombée vers l'extérieur et se détacher de la masse de produit contenue à l'intérieur de la poche.The sheet 3 can advantageously be shaped so as to at rest take a slightly domed outward shape and detach from the mass of product contained inside the bag.

Le produit se présente sous la forme d'une couche mince entre les feuilles 2,3.The product is in the form of a thin layer between the leaves 2,3.

L'épaisseur du produit est sensiblement constante ou légèrement supérieure au centre de la poche, étant comprise de préférence entre 1 et 6 mm, et de préférence encore entre 2 et 4 mm.The thickness of the product is substantially constant or slightly higher than the center of the pocket, being comprised of preferably between 1 and 6 mm, and more preferably between 2 and 4 mm.

Ainsi, l'épaisseur de produit est par exemple de 0,5 mm au voisinage de la périphérie et elle est comprise entre 2 et 4 mm au voisinage du centre de la poche.Thus, the product thickness is for example 0.5 mm at near the periphery and it is between 2 and 4 mm at the near the center of the pocket.

L'épaisseur de la feuille 3, perméable au produit, est comprise entre 5 µm et 1 mm, de préférence entre 40 µm et 500 µm, et de préférence encore, entre 100 µm et 300 µm.The thickness of the sheet 3, permeable to the product, is between 5 µm and 1 mm, preferably between 40 µm and 500 µm, and more preferably between 100 µm and 300 µm.

Les feuilles 2,3 peuvent être réalisées en un même matériau ou en des matériaux différents.The sheets 2,3 can be made of the same material or in different materials.

On peut ainsi réaliser la poche de conditionnement 1 en polyéthylène (PE), en polychlorure de vinyle, en polyéthylène téréphtalate(PET), ou en un copolymère PE/PET, non limitativement.It is thus possible to produce the packaging bag 1 in polyethylene (PE), polyvinyl chloride, polyethylene terephthalate (PET), or a PE / PET copolymer, not restrictively.

On peut encore réaliser la poche de conditionnement 1 en utilisant des feuilles constituées chacune par exemple par un stratifié de polyéthylène téréphtalate et d'aluminium ou un stratifié de polyéthylène téréphtalate et de polyéthylène.It is also possible to produce the packaging bag 1 in using sheets each consisting for example of a polyethylene terephthalate and aluminum laminate or a polyethylene terephthalate and polyethylene laminate.

L'utilisation de films multicouches pour réaliser la poche peut s'avérer utile pour empêcher l'échappement de certains constituants du produit conditionné vers l'extérieur, au travers des parois de la poche, en l'absence d'utilisation.The use of multilayer films to make the pocket can be useful in preventing the escape of certain constituents of the product packaged outside, through pocket walls, when not in use.

La région perméable au produit peut être réalisée comme dans l'exemple représenté sur les figures 1 et 2 par de simples perforations de la feuille supérieure 3, le diamètre et le nombre de ces perforations étant choisis en fonction de la nature du produit à conditionner et à distribuer et des conditions d'utilisation de la poche.The region permeable to the product can be produced as in the example shown in Figures 1 and 2 by simple perforations of the top sheet 3, the diameter and the number of these perforations being chosen according to the nature of the product to condition and distribute and conditions of use of the poached.

En variante, on peut utiliser pour constituer la feuille supérieure 3 un matériau intrinséquement perméable au produit à conditionner et à distribuer, tel qu'un matériau tissé ou non tissé ou spongieux.Alternatively, one can use to form the sheet superior 3 a material intrinsically permeable to the product to package and distribute, such as woven or non-woven material or spongy.

Dans une variante encore, représentée sur la figure 18, on peut utiliser pour constituer la région perméable au produit une superposition d'un film perforé 3 apte à permettre le passage du produit au travers des perforations et d'un film poreux 3" en matériau tissé ou non tissé ou spongieux, s'étendant en regard desdites perforations et destiné par exemple à assurer une distribution plus homogène du produit ou à modifier la sensation au toucher. Ce film poreux 3" peut s'étendre sur toute la surface du film perforé ou seulement sur la région perforée de ce dernier.In another variant, shown in FIG. 18, we can use to constitute the region permeable to the product a superimposition of a perforated film 3 capable of allowing the passage of the produced through perforations and a 3 "porous film in woven or non-woven or spongy material extending opposite said perforations and intended for example to ensure a more homogeneous distribution of the product or to modify the sensation to touch. This porous 3 "film can extend over the entire surface of the perforated film or only on the perforated region thereof.

On a illustré sur les figures 3 à 7 différentes étapes d'un premier procédé pour réaliser la poche de conditionnement 1.We illustrated in Figures 3 to 7 different stages of a first process for making the packaging bag 1.

On dépose, comme illustré sur les figures 3 et 4, au centre de la face supérieure de la feuille arrière 2, la masse de produit 4 sortant d'une filière d'extrusion à bec large, non représentée.We place, as illustrated in Figures 3 and 4, in the center of the upper face of the back sheet 2, the mass of product 4 leaving a wide-spout extrusion die, not shown.

La feuille avant 3 munie de sa pellicule amovible 5 est ensuite rapportée sur la masse de produit 4 comme représenté sur la figure 5, en étant choisie suffisamment grande pour couvrir celle-ci.The front sheet 3 provided with its removable film 5 is then reported on the mass of product 4 as shown on the Figure 5, being chosen large enough to cover it.

Ensuite, comme illustré sur la figure 6, la feuille avant 3 est pressée contre la feuille arrière 2 reposant sur une surface plane rigide pour étaler la masse de produit 4 et former un sandwich d'une mince couche de pâte étalée entre les feuilles 2 et 3. Then, as illustrated in Figure 6, the front sheet 3 is pressed against the back sheet 2 resting on a surface rigid plane to spread the mass of product 4 and form a sandwich a thin layer of dough spread between sheets 2 and 3.

Après étalement, on obtient une masse de produit 4 d'épaisseur sensiblement uniforme sur toute la surface interne des feuilles 2 et 3, comme illustré sur la figure 7.After spreading, a mass of product 4 is obtained substantially uniform over the entire internal surface of the sheets 2 and 3, as illustrated in FIG. 7.

Les feuilles 2 et 3 sont ensuite pressées sur leur pourtour l'une contre l'autre à partir de leur bord libre sur une largeur e et les régions des feuilles ainsi rapprochées sont scellées sur quatre côtés au travers d'une épaisseur résiduelle de produit, par toutes techniques connues en soi, pour former la poche 1.Sheets 2 and 3 are then pressed around their edges one against the other from their free edge over a width e and the regions of the leaves so close together are sealed on four sides through a residual thickness of product, by all techniques known per se, to form the bag 1.

Comme moyens de scellage utilisables on peut citer par exemple le soudage à ultra-sons ou à haute fréquence.As sealing means which can be used, mention may, for example, be made ultrasonic or high frequency welding.

La pellicule de protection 5 permet de fermer de façon hermétique la poche 1 en l'absence d'utilisation.The protective film 5 allows to close so airtight pocket 1 when not in use.

Après retrait de celle-ci, l'utilisateur peut prélever du produit au travers des perforations 6 de la feuille avant 3.After removing it, the user can withdraw produced through perforations 6 of the front sheet 3.

On va maintenant décrire un deuxième exemple de procédé pour réaliser la poche de conditionnement 1, en référence aux figures 8 à 15.We will now describe a second example of a process for make the packaging bag 1, with reference to FIGS. 8 to 15.

On part d'un fourreau 12 ouvert à son extrémité supérieure 13.We start from a sheath 12 open at its upper end 13.

Ce fourreau 12 est réalisé dans une matière plastique souple, telle que celle utilisée pour fabriquer les feuilles 2 et 3 de l'exemple de réalisation précédent.This sheath 12 is made of a flexible plastic material, such as that used to make sheets 2 and 3 of the previous embodiment example.

Le fourreau 12 est obtenu en rapprochant face contre face deux feuilles 14 et 15 de même forme et en les soudant à leur périphérie sur trois côtés seulement.The sleeve 12 is obtained by bringing face to face two sheets 14 and 15 of the same shape and welding them to their periphery on three sides only.

En variante, on peut former le fourreau 12 en repliant sur elle-même une bande souple unique, auquel cas il suffit de souder deux côtés seulement.Alternatively, the sheath 12 can be formed by folding over itself a single flexible strip, in which case it suffices to weld two sides only.

Le fourreau 12 comporte sur une face principale des perforations et une pellicule amovible, que l'on n'a pas représentées dans un souci de clarté du dessin.The sheath 12 has on a main face of the perforations and a removable film, which we have not shown for the sake of clarity of the drawing.

Le fourreau 12 est rectangulaire à sa partie inférieure et s'élargit à son extrémité supérieure ouverte pour former un entonnoir 16 destiné à faciliter l'introduction à l'intérieur du fourreau d'un bec de remplissage en produit.The sheath 12 is rectangular at its lower part and widens at its open upper end to form a funnel 16 intended to facilitate the introduction inside the sheath of a product filling spout.

On a indiqué par des pointillés les lignes d'assemblage S des feuilles 14 et 15. The assembly lines S have been indicated by dotted lines. sheets 14 and 15.

On a représenté en élévation sur la figure 9 le fourreau 12 avant le remplissage, qui s'effectue au moyen d'un bec 17 de large diamètre, introduit par l'extrémité supérieure 13, pour délivrer vers le bas par un orifice 19 à l'intérieur du fourreau la masse de produit 4. L'orifice 19 est situé, lors de la distribution, à mi-hauteur environ des côtés parallèles 20 de la partie inférieure du fourreau 12.The sleeve 12 is shown in elevation in FIG. 9 before filling, which is done by means of a spout 17 wide diameter, introduced by the upper end 13, to deliver towards the bottom through an opening 19 inside the sheath the mass of product 4. The orifice 19 is located, during the distribution, at about halfway up the parallel sides 20 of the bottom of the scabbard 12.

On a représenté sur la figure 11 le fourreau 12 après retrait du bec de remplissage 17.There is shown in Figure 11 the sleeve 12 after removal filling spout 17.

La masse de produit 4 est alors étalée en pressant l'une contre l'autre les deux faces principales du fourreau 12, comme illustré sur la figure 12.The mass of product 4 is then spread by pressing one against the other the two main faces of the sheath 12, as illustrated in figure 12.

L'étalement de la masse de produit 4 fait remonter celle-ci jusqu'à la base de l'entonnoir 16, donc au dessus de l'extrémité supérieure des côtés 20 de la partie inférieure du fourreau, comme représenté sur la figure 13.Spreading the mass of product 4 brings it up to the base of funnel 16, therefore above the end upper sides 20 of the lower part of the sheath, as shown in figure 13.

Le fourreau 12 est ensuite scellé après rapprochement des feuilles 14 et 15 selon une ligne de fermeture reliant les extrémités supérieures des côtés 20, au travers d'une épaisseur résiduelle de produit, comme illustré sur la figure 14.The sheath 12 is then sealed after bringing the sheets 14 and 15 along a closing line connecting the ends upper sides 20, through a residual thickness of product, as shown in Figure 14.

Le fourreau 12 est ensuite découpé selon une ligne de coupe parallèle au côté dernièrement scellé, pour séparer l'entonnoir 16 de la partie inférieure du fourreau qui forme alors une poche de conditionnement identique à la poche 1 précédemment décrite, quoique remplie différemment.The sheath 12 is then cut along a cutting line parallel to the last sealed side, to separate the funnel 16 from the lower part of the sheath which then forms a pocket of identical packaging to bag 1 previously described, although completed differently.

On peut rapporter sur les deux feuilles assemblées pour contenir le produit un cache comme mentionné précédemment.We can report on the two sheets assembled for contain the product a cache as previously mentioned.

On a représenté sur les figures 16 et 17 une poche 1' comportant une feuille arrière 3', une feuille avant perforée 8', un cache 9' et une pellicule de protection amovible 5' munie d'une languette de préhension 7'.FIGS. 16 and 17 show a pocket 1 ' comprising a rear sheet 3 ', a perforated front sheet 8', a cover 9 'and a removable protective film 5' provided with a grip tab 7 '.

Les feuilles 3' et 8' sont assemblées pour contenir le produit 4. Le cache 9' est ajouré en son centre pour permettre à l'utilisateur de prélever du produit en passant son doigt ou un applicateur sur la feuille avant 8' après retrait de la pellicule amovible 5'. Cette dernière est fixée à sa périphérie sur la face externe du cache 9'. La feuille avant 8' est traversée par des perforations régulièrement réparties sur toute sa surface.The 3 'and 8' sheets are assembled to contain the product 4. The cover 9 'is perforated in its center to allow the user to withdraw the product by passing his finger or a applicator on the sheet before 8 'after removal of the film removable 5 '. The latter is fixed to its periphery on the face external cover 9 '. The front sheet 8 'is crossed by perforations regularly distributed over its entire surface.

Le cache 9' peut être soudé sur la feuille avant 8' lors de l'assemblage de cette dernière avec la feuille arrière 3', et il peut être réalisé dans une matière plastique relativement rigide et opaque, de manière à faciliter le maniement de la poche et conférer à cette dernière un aspect esthétique agréable. Dans une variante non représentée, on peut utiliser pour maintenir et masquer les feuilles souples sur leur pourtour deux éléments formant cadre en matière plastique relativement rigide, superposés et assemblés comme pour retenir le tronçon de film d'une diapositive. Avant leur assemblage, les deux éléments peuvent être indépendants ou reliés par une charnière film et l'un seulement des éléments peut être ajouré pour permettre à l'utilisateur de prélever le produit.The cover 9 'can be welded to the front sheet 8' during the assembly of the latter with the back sheet 3 ', and it can be made of a relatively rigid plastic and opaque, so as to facilitate the handling of the pocket and give the latter a pleasant aesthetic aspect. In a variant not shown, can be used to hold and hide leaves flexible around their periphery two elements forming a frame relatively rigid plastic, stacked and assembled as for retain the stretch of film on a slide. Before their assembly, the two elements can be independent or linked by a film hinge and only one of the elements can be perforated to allow the user to collect the product.

La poche 1 ou 1' peut avantageusement être utilisée dans un accessoire de maquillage 25 tel que représenté schématiquement en perspective sur la figure 19.The pocket 1 or 1 'can advantageously be used in a makeup accessory 25 as shown diagrammatically in perspective in figure 19.

L'accessoire 25 comporte un boítier 26 muni d'un couvercle pivotant 27 qui peut loger en son fond un miroir 28.The accessory 25 comprises a box 26 provided with a cover swivel 27 which can house a mirror 28 at its bottom.

Le corps du boítier 26 loge un tiroir coulissant 29 dont le fond 33 est rigide et qui peut être tiré pour recevoir la poche 1 ou 1' dont la taille est adaptée.The body of the housing 26 houses a sliding drawer 29, the bottom 33 is rigid and can be pulled out to receive pocket 1 or 1 'whose size is suitable.

La poche 1 ou 1' est retenue dans le corps du boítier 26 une fois le tiroir 29 en place par un cadre 30 définissant un accès 31 à la face supérieure de la poche.The pocket 1 or 1 'is retained in the body of the housing 26 a times the drawer 29 in place by a frame 30 defining an access 31 to the upper side of the pocket.

Le produit est prélevé au moyen du doigt ou d'un applicateur 32, amené au contact de la région perméable de la feuille avant 3 après enlèvement de la pellicule de protection 5.The product is removed using the finger or an applicator 32, brought into contact with the permeable region of the front sheet 3 after removal of the protective film 5.

Avantageusement, comme représenté sur la figure 20, l'applicateur 32 se loge dans l'accessoire 25 en l'absence d'utilisation entre le cadre 30 et le couvercle 27 rabattu sur le corps du boítier.Advantageously, as shown in FIG. 20, the applicator 32 is housed in the accessory 25 in the absence of use between the frame 30 and the cover 27 folded down on the body of the housing.

La souplesse de la feuille avant perméable au produit permet d'assurer le vidage complet de la poche en l'appliquant contre la feuille arrière ; les deux feuilles sont alors l'une au contact de l'autre sur la majeure partie de leur surface. The flexibility of the permeable front sheet allows ensure the complete emptying of the bag by applying it against the back sheet; the two sheets are then one in contact with the other on most of their surface.

L'invention permet ainsi le conditionnement d'un produit coûteux sans perte de produit pour l'utilisateur.The invention thus allows the packaging of a product expensive without loss of product for the user.

Bien entendu l'invention n'est pas limitée aux exemples de réalisation qui viennent d'être décrits.Of course, the invention is not limited to the examples of realization which have just been described.

On peut notamment modifier la géométrie de la poche et adopter une forme non pas rectangulaire mais circulaire par exemple.One can in particular modify the geometry of the pocket and adopt a shape not rectangular but circular for example.

Par ailleurs, la poche peut être reçue non pas dans un tiroir coulissant mais dans une simple fente du boítier d'un accessoire de maquillage semblable à celui décrit précédemment.Furthermore, the pocket can be received not in a drawer sliding but in a simple slot of the case of an accessory of makeup similar to that described above.

La poche peut également servir d'échantillon à insérer dans des magazines ou à envoyer par courrier, permettant de tester le produit contenu à l'intérieur.The pocket can also be used as a sample to insert into magazines or send by mail, to test the product contained inside.
