Description

La présente invention a trait à un ensemble, tel qu'utilisé notamment pour le conditionnement de produits cosmétiques, en particulier pour le conditionnement de produits sous forme d'un gel ou d'une crème.The present invention relates to an assembly, as used in particular for the conditioning of cosmetic products, in particular for conditioning of products in the form of a gel or a cream.

L'invention vise en particulier la distribution facilitée du contenu de tels pots. Typiquement, dans le domaine cosmétique, le contenu du pot est prélevé par l'utilisatrice, au moyen d'un ou plusieurs doigts qu'elle introduit dans le pot. Bien évidemment, l'opération est de plus en plus malaisée au fur et à mesure que l'on se rapproche du fond du pot, en particulier pour des pots de faible section relativement à leur hauteur.The invention aims in particular the facilitated distribution of the contents of such pots. Typically, in the cosmetic field, the contents of the pot are taken by the user, by means of one or more fingers that it introduces into the pot. Good obviously, the operation is more and more difficult as one gets closer to the bottom of the pot, especially for pots of small section relative to their height.

Sont connus des pots équipés de systèmes à piston ou à soufflet, et configurés de manière à, en réponse à une pression exercée sur le fond du pot, ou en réponse à une rotation d'un organe de manoeuvre, provoquer la sortie dosée d'un produit contenu à l'intérieur du pot.Are known pots equipped with piston or bellows systems, and configured way to, in response to pressure exerted on the bottom of the pot, or in response to a rotation of an operating member, causing the metered output of a product content inside the pot.

Ainsi, le brevet d'invention FR 1 570 600 décrit un dispositif comportant un conditionnement extérieur et un conditionnement intérieur, sous forme d'un soufflet, monté sur un piston. Le déplacement du piston, de bas en haut, de manière à comprimer le soufflet au fil des utilisations, et provoquer la sortie du produit, se fait soit par une poussée manuelle directement sur le fond, soit par rotation du conditionnement extérieur par rapport à un dispositif de distribution solidaire du conditionnement intérieur. Le mécanisme est compliqué. De ce fait, le coût de revient du pot est important, et incompatible avec les impératifs économiques dictés par les circuits de la grande distribution.Thus, patent FR 1 570 600 describes a device comprising a packaging and inner packaging, in the form of a bellows, mounted on a piston. The movement of the piston, from bottom to top, in order to compress the bellows during the use, and to cause the exit of the product, is done either by a manual push directly on the bottom, or by rotation of the outer packaging with respect to a dispensing device integral with the inner packaging. The mechanism is complicated. As a result, the cost of the pot is important, and incompatible with the imperatives dictated by the circuits of mass distribution.

Le brevet US 4 456 134 décrit un autre système de conditionnement dans lequel, on ajuste le volume d'un réceptacle, au moyen d'une partie souple, de type soufflet par exemple, et dont la hauteur peut être réduite par vissage, l'une sur l'autre, de deux parties cylindriques formant un conditionnement extérieur. La hauteur visible du récipient s'en trouve diminuée d'autant. De la même manière que pour le dispositif discuté précédemment, ce système est compliqué et coûteux. US Pat. No. 4,456,134 describes another packaging system in which, the volume of a receptacle is adjusted by means of a flexible part of a type bellows for example, and whose height can be reduced by screwing, one on the other, two cylindrical parts forming an outer package. The visible height of the container is diminished accordingly. In the same way that for the device discussed previously, this system is complicated and expensive.

Le brevet US 3 156 279 décrit un pot souple ayant une structure rigide de protection.US Patent 3,156,279 discloses a flexible pot having a rigid structure of protection.

Aussi, est-ce un des objets de l'invention que de réaliser un ensemble de type à pot dont la distribution du contenu soit aisé, et qui résolve en tout ou partie les problèmes discutés ci-avant en référence aux dispositifs connus.Also, is it an object of the invention to make a set of pot whose distribution of content is easy, and which solves all or part of the problems discussed above with reference to known devices.

C'est en particulier un objet de l'invention que de réaliser un tel pot qui soit économique à réaliser, et simple à utiliser.It is in particular an object of the invention to make such a pot which is Economical to achieve, and simple to use.

C'est en particulier un autre objet de l'invention que de réaliser un pot, avec lequel est conservée la gestuelle de prélèvement au moyen d'un doigt, et dont la facilité de distribution n'est sensiblement pas affectée au fil des distributions.It is in particular another object of the invention to make a pot, with which is preserved the gesture of sampling with a finger, and whose ease distribution is not significantly affected over the distributions.

D'autres objets encore apparaítront dans la description détaillée qui suit.Still other objects will appear in the following detailed description.

Selon l'invention, ces objets sont atteints, en tout ou partie, en réalisant un ensemble, pour le conditionnement d'un produit, notamment sous forme d'une crème ou d'un gel, comprenant :

  • a) un pot souple contenant le produit, le pot comportant une première extrémité fermée par un fond et une seconde extrémité, opposée à la première, formant un col délimitant une ouverture ;
  • b) une structure rigide à l'intérieur de laquelle est monté de manière amovible le pot souple, la structure rigide s'étendant sensiblement sur toute la hauteur du pot souple située sous le col ;
    •    le pot souple étant configuré de sorte que, une fois extrait de la structure rigide, une pression, exercée sur le pot souple provoque une déformation de ce dernier, et un déplacement du produit en direction de ladite ouverture, le pot reprenant par rappel élastique sa forme non déformée lorsque cesse ladite pression.According to the invention, these objects are achieved, in whole or in part, by producing an assembly, for the packaging of a product, in particular in the form of a cream or a gel, comprising:
  • a) a flexible jar containing the product, the jar comprising a first end closed by a bottom and a second end, opposite to the first, forming a neck defining an opening;
  • b) a rigid structure within which is mounted removably the flexible pot, the rigid structure extending substantially over the entire height of the flexible pot located under the neck;
    • the flexible pot being configured so that, once extracted from the rigid structure, a pressure exerted on the flexible pot causes a deformation of the latter, and a displacement of the product towards said opening, the pot taking up by elastic return its undeformed shape when said pressure ceases.

    Par "structure rigide" on entend une structure qui, en réponse à une contrainte axiale, offre une résistance supérieure à la résistance offerte par le pot souple en réponse à la même contrainte axiale. By "rigid structure" is meant a structure which, in response to a constraint axial, offers superior resistance to the resistance offered by the flexible pot in response to the same axial stress.

    De préférence, le matériau formant la structure rigide est de dureté shores supérieure à la dureté shores du matériau formant le pot souple.Preferably, the material forming the rigid structure is of shores hardness greater than the hardness shores of the material forming the flexible pot.

    Ainsi, du fait de la présence de la structure rigide, l'ensemble présente une parfaite tenue, lorsqu'il est disposé sur un présentoir, ou lors de son stockage, en particulier lors de son empilement.Thus, because of the presence of the rigid structure, the assembly presents a perfect hold, when it is placed on a display, or when it is stored, in especially when stacking.

    A l'utilisation, la consommatrice extrait le pot de la structure rigide. Cette opération est facilitée par le fait qu'au moins une partie du col, et, le cas échéant, du couvercle qui obture l'ouverture qu'il délimite, se situe au dessus de la structure rigide. De préférence, l'intégralité du col se situe au dessus de la structure rigide, un bord supérieur de cette dernière se situant sensiblement au niveau de l'épaulement formé à la base du col.In use, the consumer extracts the pot from the rigid structure. This operation is facilitated by the fact that at least part of the pass, and, where appropriate, the cover that closes the opening it delimits, is located above the structure rigid. Preferably, the entire neck is located above the rigid structure, an upper edge of the latter being substantially at the level of the shoulder formed at the base of the neck.

    Après dégagement de l'ouverture du pot, elle exerce une pression sur les parois du pot, de manière à forcer le produit en direction de l'ouverture. Le produit peut alors être prélevé de manière simple, en particulier au moyen d'un doigt ou de tout autre dispositif d'application. Le produit est alors appliqué de manière conventionnelle.After clearing the opening of the pot, it exerts a pressure on the walls of the pot, so as to force the product towards the opening. The product can then be taken in a simple way, especially by means of a finger or any other application device. The product is then applied in a conventional.

    Lorsque cesse la pression sur les parois du pot, le produit restant redescend en direction du fond du pot. L'ouverture peut être refermée en attente d'une prochaine utilisation.When the pressure on the walls of the pot stops, the remaining product goes down again direction of the bottom of the pot. The opening can be closed waiting for a next use.

    Alternativement, dans le cas de la réalisation d'une composition, notamment de coloration capillaire, obtenue par le mélange extemporané d'un colorant et d'un oxydant, il est possible d'imaginer que l'un des produits soit sous forme d'une crème conditionnée dans le pot souple.Alternatively, in the case of the realization of a composition, in particular of capillary coloration, obtained by the extemporaneous mixing of a dye and a oxidant, it is possible to imagine that one of the products is in the form of a cream packaged in the flexible jar.

    L'autre produit, en particulier le colorant, est conditionné séparément, notamment dans un logement ménagé dans le fond de la structure rigide, et maintenu isolé du pot souple par une pellicule amovible, notamment en un complexe à base d'aluminium. The other product, in particular the dye, is packaged separately, in particular in a housing formed in the bottom of the rigid structure, and kept isolated from flexible pot with a removable film, in particular a complex based aluminum.

    A l'utilisation, la consommatrice extrait le pot souple de la structure rigide. Elle enlève la pellicule amovible qui obture le logement formé dans le fond de la structure rigide et qui contient le colorant. Elle dégage l'ouverture du pot souple et en presse le contenu à l'intérieur de la structure rigide. Elle mélange le tout au moyen d'un outil approprié de manière à homogénéiser la composition de coloration, et l'applique de manière conventionnelle, en particulier sous forme de mèches.In use, the consumer extracts the flexible jar from the rigid structure. She removes the removable film that closes the housing formed in the bottom of the rigid structure and which contains the dye. It releases the opening of the flexible pot and in press the contents inside the rigid structure. She mixes everything means of a suitable tool so as to homogenize the composition of coloration, and applies it in a conventional manner, in particular in the form of wicks.

    La fixation amovible de la structure rigide sur le pot souple s'effectue par accrochage mécanique notamment par encliquetage, vissage, ou système à baïonnette. De préférence, cette fixation amovible est rendue possible par la présence de zones du pot plus épaisses et donc plus rigides, aux endroits où doit se faire l'accrochage. De telles zones d'épaisseur plus importantes peuvent être prévues notamment au niveau du fond du pot.The removable attachment of the rigid structure on the flexible pot is effected by mechanical fastening, particularly by snap-fastening, screwing, or system bayonet. Preferably, this removable attachment is made possible by the thicker and therefore more rigid areas of the pot, where hang on. Such areas of greater thickness may be provided especially at the bottom of the pot.

    Le col du pot peut également être d'épaisseur plus importante, en vue de permettre l'accrochage, notamment par vissage, d'un bouchon. A cet effet, et de préférence, une surface extérieure du col comporte un filetage apte à coopérer avec un filetage correspondant prévu sur une surface intérieure d'un bouchon.The neck of the pot may also be thicker, with a view to allow the attachment, especially by screwing, a plug. For this purpose, and preferably, an outer surface of the neck has a thread capable of cooperating with a corresponding thread provided on an inner surface of a plug.

    D'autres moyens de fixation du couvercle sur le pot peuvent être prévus. A titre d'exemples, l'accrochage peut se faire par encliquetage ou par un système à rampes.Other means of fixing the lid on the pot can be provided. As examples, snapping can be done by snapping or by a system to ramps.

    De la même manière que la structure rigide, le couvercle est réalisé en un matériau rigide. Dans la pratique, peuvent être utilisés des matériaux identiques ou différents.In the same way as the rigid structure, the lid is made in one rigid material. In practice, identical materials can be used or different.

    Avantageusement, en position montée du couvercle sur le pot, une partie du couvercle est sensiblement au contact d'une partie correspondante de la structure rigide. Ainsi, les pots peuvent être empilés sans risque d'écrasement.Advantageously, in the mounted position of the lid on the pot, part of the cover is substantially in contact with a corresponding part of the structure rigid. Thus, the pots can be stacked without risk of crushing.

    A titre d'exemple préférentiel, le couvercle comprend un bord annulaire, disposé à l'opposé d'un fond du couvercle, et qui, en position montée du couvercle sur le fond, est sensiblement au contact d'une portion annulaire de la structure rigide, en particulier de son bord supérieur.By way of a preferred example, the lid comprises an annular rim, disposed at the opposite of a bottom of the lid, and which, in the mounted position of the lid on the bottom, is substantially in contact with an annular portion of the rigid structure, particular of its upper edge.

    De préférence, le pot souple comprend au voisinage de son fond des moyens d'accrochage, notamment sous forme de nervures ou ergots, aptes à coopérer de manière réversible avec des moyens d'accrochage complémentaires prévus au voisinage du fond de la structure rigide.Preferably, the flexible pot comprises in the vicinity of its bottom means fastening, in particular in the form of ribs or lugs, capable of cooperating with reversibly with additional fastening means provided for in near the bottom of the rigid structure.

    Avantageusement, le montage/démontage de la structure rigide relativement au pot souple se fait en réponse à la mise en rotation de l'un relativement à l'autre. Le sens du mouvement de rotation de la structure rigide relativement au pot, lors du démontage, peut être identique au sens de dévissage du bouchon du pot. Alternativement, le sens de rotation, en vue du démontage, est inverse au sens de rotation du bouchon du pot en vue de son dévissage.Advantageously, the assembly / disassembly of the rigid structure relative to the flexible pot is in response to the rotation of one relative to the other. The sense of the rotational movement of the rigid structure relative to the pot, during the disassembly, may be identical to the direction of unscrewing the cap of the pot. Alternatively, the direction of rotation, with a view to dismantling, is the opposite in the sense of rotation of the cap of the pot in order to unscrew it.

    Le pot souple peut être réalisé par injection soufflage, notamment en un matériau élastomérique ou en une polyoléfine, notamment un polyéthylène ou un polypropylène, obtenue par catalyse métallocene, éventuellement en mélange avec une autre polyoléfine.The flexible pot may be made by injection blow molding, in particular a material elastomer or a polyolefin, in particular a polyethylene or a polypropylene, obtained by metallocene catalysis, optionally in admixture with another polyolefin.

    A titre d'exemples plus spécifiques on peut citer un matériau (polyéthylène metallocene) commercialisé sous la marque Exact™ par la société DSM, ou encore un matériau (polypropylène métallocene) commercialisé sous la marque Metocene™ par la société TARGOR.As more specific examples, mention may be made of a material (polyethylene metallocene) marketed under the trademark Exact ™ by the company DSM, or another material (polypropylene metallocene) marketed under the brand name Metocene ™ by TARGOR.

    Il est possible également d'utiliser un matériau formé d'un mélange d'une polyoléfine obtenue par catalyse metallocène et d'une polyoléfine traditionnelle, et ceci afin de jouer sur la souplesse du matériau, indépendamment de l'épaisseur des parois.It is also possible to use a material formed of a mixture of a polyolefin obtained by metallocene catalysis and a conventional polyolefin, and this in order to play on the flexibility of the material, regardless of the thickness walls.

    Dans le cadre d'un tel processus d'injection soufflage, en jouant sur les épaisseurs de la préforme, et sur les variations de diamètre du corps du pot souple, on obtient une variation des épaisseurs de la paroi du corps. In the context of such an injection blow molding process, playing on the thicknesses of the preform, and on the variations of diameter of the body of the flexible pot, we obtain a variation of the thicknesses of the body wall.

    De manière plus spécifique, la préforme est d'épaisseur plus importante au niveau du col du pot, et au niveau du fond. De cette manière, lors du soufflage, la variation de diamètre entre la base du col et l'épaulement formé entre le col et la paroi latérale du pot va provoquer un amincissement de la paroi en direction du diamètre le plus large du pot. Le col sera donc plus épais que l'épaulement et que la paroi latérale du pot.More specifically, the preform is thicker at the level of the neck of the pot, and at the bottom. In this way, during blowing, the variation in diameter between the base of the neck and the shoulder formed between the neck and the side wall of the pot will cause a thinning of the wall towards the widest diameter of the pot. The collar will therefore be thicker than the shoulder and that the side wall of the pot.

    A titre purement indicatif, au niveau du col, l'épaisseur peut être de l'ordre de 1,5 mm. L'épaisseur diminue progressivement sur l'épaulement, en direction de la paroi latérale du corps du pot. L'épaisseur moyenne de cette dernière peut être de l'ordre de 0,7 mm à 0,8 mm. L'épaisseur du fond peut être du même ordre que l'épaisseur de la paroi du col.As a purely indicative, at the neck, the thickness may be of the order of 1.5 mm. The thickness gradually decreases on the shoulder, towards the side wall of the pot body. The average thickness of the latter may be 0.7 mm to 0.8 mm. The thickness of the bottom can be of the same order as the thickness of the wall of the neck.

    A titre d'exemple également, la structure rigide peut être réalisée en matériau thermoplastique, notamment en polypropylène ou polyéthylène, et obtenue par exemple, par injection. Alternativement, la structure rigide est en métal, en verre, ou en aluminium.For example also, the rigid structure can be made of material thermoplastic, in particular polypropylene or polyethylene, and obtained by example, by injection. Alternatively, the rigid structure is made of metal, glass, or aluminum.

    L'ensemble selon l'invention peut être utilisé avantageusement pour le conditionnement, et éventuellement la préparation d'un produit cosmétique, notamment d'un produit de coiffage, de coloration capillaire, de soin de la peau, ou de soin du cheveu.The assembly according to the invention can advantageously be used for conditioning, and possibly the preparation of a cosmetic product, in particular a styling product, hair coloring, skincare, or hair care.

    L'invention consiste, mises à part les dispositions exposées ci-dessus, en un certain nombre d'autres dispositions qui seront explicitées ci-après, à propos d'exemples de réalisation non limitatifs, décrits en référence aux figures annexées, parmi lesquelles :

    • la figure 1 est une vue assemblée d'un ensemble selon un mode de réalisation préférentiel de l'invention ;
    • la figure 2 est une vue de l'ensemble de la figure 1 en position démontée ;
    • - la figure 3 est une vue en coupe longitudinale de l'ensemble de la figure 1 ; et
    • la figure 4 illustre l'utilisation du pot représenté aux figures 1-3.
    The invention consists, apart from the arrangements described above, in a certain number of other arrangements which will be explained below, with reference to nonlimiting exemplary embodiments, described with reference to the appended figures, among which:
    • Figure 1 is an assembled view of an assembly according to a preferred embodiment of the invention;
    • Figure 2 is a view of the assembly of Figure 1 in disassembled position;
    • - Figure 3 is a longitudinal sectional view of the assembly of Figure 1; and
    • Figure 4 illustrates the use of the pot shown in Figures 1-3.

    L'ensemble 1 représenté aux figures 1-3 comprend un pot souple 2, une armature rigide 30, et un bouchon 40. L'ensemble 1 est d'axe longitudinal X.The assembly 1 represented in FIGS. 1-3 comprises a flexible pot 2, an armature rigid 30, and a plug 40. The assembly 1 is of longitudinal axis X.

    Le pot souple est réalisé par injection soufflage en un matériau commercialisé sous la marque Exact™ par la société DSM.The flexible pot is made by injection blow molding of a commercial material under the Exact ™ brand by DSM.

    Il comprend un corps 3 délimité par une paroi latérale 4 dont le diamètre diminue progressivement en direction d'un fond fermé 5. L'autre extrémité se termine par un col 6, lequel est relié à la paroi latérale par un épaulement transversal 7. Un bord libre du col 6 délimite une ouverture 10.It comprises a body 3 delimited by a side wall 4 whose diameter decreases progressively towards a closed bottom 5. The other end ends with a neck 6, which is connected to the side wall by a transverse shoulder 7. A free edge of the neck 6 defines an opening 10.

    La surface extérieure du col 6 comprend un filetage 8 apte à coopérer avec un filetage correspondant prévu sur une surface interne du bouchon 40.The outer surface of the neck 6 comprises a threading 8 adapted to cooperate with a corresponding thread provided on an inner surface of the plug 40.

    Comme il apparaít sur la vue en coupe de la figure 3, le fond 5 et le col 6 sont d'épaisseur supérieure à l'épaisseur de la paroi latérale 4 et de l'épaulement transversal 7.As it appears on the sectional view of FIG. 3, the bottom 5 and the neck 6 are thicker than the thickness of the side wall 4 and the shoulder transversal 7.

    La surépaisseur du col permet d'assurer un bon accrochage par vissage entre le couvercle 40 et le corps 3. La surépaisseur du fond 5 permet de conférer de la tenue au pot lorsqu'il est posé sur une surface plane. Elle permet en outre de favoriser l'accrochage réversible entre le pot souple 2 et la structure rigide 30 à laquelle il va être fait référence par la suite.The extra thickness of the neck makes it possible to ensure a good fastening by screwing between the cover 40 and the body 3. The overthickness of the bottom 5 makes it possible to confer held in the pot when placed on a flat surface. It also allows promote the reversible hooking between the flexible pot 2 and the rigid structure 30 to which will be referred to later.

    Sur sa surface périphérique externe, le fond présente trois portions de nervures 9, espacées de 120°, et destinées à l'accrochage réversible de la structure rigide 30 sur le pot 2.On its outer peripheral surface, the bottom has three portions of ribs 9, spaced 120 °, and intended for the reversible attachment of the rigid structure 30 on the pot 2.

    La structure rigide 30 est réalisée par injection en polypropylène. Elle comprend une paroi latérale 31 de profil similaire au profil extérieur de la paroi latérale 4 du pot souple 2. Sa section interne est toutefois légèrement supérieure à celle du pot souple de manière à ce que ce dernier puisse y être introduit avec un léger jeu. The rigid structure 30 is made by polypropylene injection. She understands a side wall 31 of profile similar to the outer profile of the side wall 4 of the flexible pot 2. Its internal section is however slightly greater than that of the pot flexible so that it can be introduced with a slight game.

    Une extrémité de la paroi latérale 31 est fermée par un fond 32. Celui ci n'est toutefois pas indispensable.One end of the side wall 31 is closed by a bottom 32. This is not however not essential.

    Au voisinage du fond 32, sur sa surface intérieure, la paroi latérale 31 présente 3 portions 33 formant saillie par rapport à la surface interne de la jupe latérale 31. Les portions 33 sont espacées à 120° et sont destinées à coopérer avec les nervures 9 prévues sur le fond du pot 2, de manière à permettre l'accrochage réversible de la structure rigide 30 sur le pot 2.In the vicinity of the bottom 32, on its inner surface, the side wall 31 has 3 portions 33 protruding from the inner surface of the side skirt 31. The portions 33 are spaced at 120 ° and are intended to cooperate with the ribs 9 provided on the bottom of the pot 2, so as to allow the hooking reversible of the rigid structure 30 on the pot 2.

    La mise en engagement des nervures 9 avec les portions d'accrochage 33 de la structure rigide se fait par la mise en rotation de quelques degrés de la structure rigide 30 relativement au pot souple 2.The engagement of the ribs 9 with the attachment portions 33 of the rigid structure is done by rotating a few degrees of structure rigid 30 relative to the flexible pot 2.

    L'autre extrémité de la paroi latérale 31 de la structure rigide 30 est ouverte et se termine par un bord libre 34. Sa section transversale interne est légèrement supérieure à la section externe de l'épaulement 7 du pot souple 2.The other end of the side wall 31 of the rigid structure 30 is open and ends with a free edge 34. Its internal cross-section is slightly greater than the outer section of the shoulder 7 of the flexible pot 2.

    En position montée, et ainsi qu'il ressort plus clairement de la vue en coupe de la figure 3, l'extrémité ouverte de la structure rigide 30 est sensiblement au niveau du bord périphérique de l'épaulement 7.In mounted position, and as is more clearly apparent from the sectional view of the 3, the open end of the rigid structure 30 is substantially at the level of peripheral edge of the shoulder 7.

    Bien que non représenté, il est possible de prévoir que le bord supérieur de la paroi latérale 4 du pot souple 2 soit en léger retrait par rapport au bord périphérique de l'épaulement 7 du pot, d'une valeur correspondant sensiblement à l'épaisseur du bord supérieur de la structure rigide 30 de sorte que le bord périphérique de l'épaulement 7 du pot souple 2 prenne appui sur le bord supérieur de la structure rigide 30.Although not shown, it is possible to provide that the upper edge of the side wall 4 of the flexible pot 2 is slightly inward with respect to the edge peripheral of the shoulder 7 of the pot, a value corresponding substantially to the thickness of the upper edge of the rigid structure 30 so that the edge peripheral of the shoulder 7 of the flexible pot 2 bears on the upper edge of the rigid structure 30.

    Le couvercle 40 comprend une jupe latérale 41 de section croissant progressivement en direction d'un bord libre 42. L'autre extrémité de la jupe 41 est fermée par une paroi transversale 43. Il est réalisé en un matériau identique au matériau formant la structure rigide 30. The lid 40 comprises a lateral skirt 41 of ascending section gradually towards a free edge 42. The other end of the skirt 41 is closed by a transverse wall 43. It is made of a material identical to the material forming the rigid structure 30.

    La section transversale du bord libre 42 du couvercle 40 est sensiblement égale à la section transversale du bord supérieur 34 de la structure rigide 30 de sorte que, en position montée, le couvercle 40 soit sensiblement en butée contre la structure rigide 30.The cross section of the free edge 42 of the cover 40 is substantially equal to the cross section of the upper edge 34 of the rigid structure 30 so that in the mounted position, the cover 40 is substantially in abutment against the structure rigid 30.

    Pour utiliser l'ensemble selon l'invention, l'utilisatrice fait tourner la structure rigide 30 relativement au pot 2, en maintenant ce dernier par le couvercle 40, et ce d'un angle suffisant pour que les ergots 9 se désengagent des rebords 33 formés sur la surface interne de la structure rigide 30.To use the assembly according to the invention, the user rotates the rigid structure 30 relative to the pot 2, maintaining the latter by the lid 40, and that of a angle sufficient for the lugs 9 to disengage the flanges 33 formed on the internal surface of the rigid structure 30.

    Après désengagement des ergots 9, elle extrait le pot souple 2 de la structure rigide 30.After disengaging the pins 9, it extracts the flexible pot 2 of the structure rigid 30.

    Elle dévisse le couvercle 40.She unscrews the lid 40.

    Ensuite, et ainsi qu'il ressort de la figure 4, l'utilisatrice exerce une pression sur la paroi latérale 4 du pot 2. Ce faisant, la section du pot est réduite, et le produit qu'il contient est forcé en direction de l'ouverture 10 . A ce moment, le produit peut être prélevé aisément au moyen d'un doigt.Then, as shown in Figure 4, the user exerts pressure on the side wall 4 of the pot 2. In doing so, the pot section is reduced, and the product it contains is forced towards the opening 10. At this moment, the product can be taken easily by means of a finger.

    Lorsque l'utilisatrice relâche la pression exercée sur le pot 2, celui-ci reprend sa forme initiale, causant ainsi le retour du produit restant dans le pot, en direction du fond 5.When the user releases the pressure exerted on the pot 2, it resumes its initial shape, thus causing the return of the product remaining in the pot, towards the background 5.

    Après utilisation partielle du contenu du pot 2, elle repositionne le couvercle 40, et stocke le pot 2 en vue d'une nouvelle utilisation, soit indépendamment de la coque rigide 30, soit en le repositionnant à l'intérieur de celle-ci.After partial use of the contents of the pot 2, it repositions the lid 40, and stores pot 2 for further use, regardless of shell rigid 30, or by repositioning it inside thereof.

    Dans la description détaillée qui précède, il a été fait référence à des modes de réalisation préférés de l'invention. Il est évident que des variantes peuvent y être apportées sans s'écarter de l'esprit de l'invention telle que revendiquée ci-après.In the above detailed description, reference has been made to modes of preferred embodiment of the invention. It is obvious that variants can be without departing from the spirit of the invention as claimed hereinafter.
