Abstract

The packaging box (1) for a solid or semi-solid product block (P) comprises a bottom (2) forming a receptacle for the block. The block is immobilised by a foam washer (8). A removable opercule (6), formed from a transparent PVC sheet, is located on the block surface and a removable cover (4) on the bottom can be used for opening or closing the box. Crenellations (32) in the opercule engaging in notches (46) in the cover ensure that opening the box by rotation of the cover causes rotation of the opercule relative to the product. This induces shearing between the opercule internal surface and the product surface.

Description

La présente invention se rapporte à un boítier pour le conditionnement et la présentation d'un produit délitable présenté sous forme de bloc solide. Généralement, ce produit est un produit de maquillage, appelé aussi « pain » ou « cake ». Ce produit peut être mis en place, dans le boítier par coulage du produit sous forme liquéfié qui se transforme, après solidification, en un produit solide et délitable, pouvant être prélevé, par l'utilisatrice, à l'aide d'un doigt, d'une houppette ou d'un pinceau. Plus particulièrement, le produit visé par l'invention, est un fard à joues, une ombre à paupières ou un fond de teint.The present invention relates to a housing for packaging and presentation of a breakable product presented in the form of a solid block. Generally, this product is a makeup product, also called “bread” or "Cake". This product can be put in place in the case by pouring the product in liquefied form which, after solidification, becomes a solid product and delitable, which can be removed by the user, using a finger, a powder puff or brush. More particularly, the product targeted by the invention, is a blush, an eye shadow or a foundation.

Le produit de maquillage liquéfié peut être présenté sous forme de pâte, obtenue en mélangeant une phase particulaire solide, soit avec une phase aqueuse, soit avec un liant, notamment une phase grasse dans un solvant ; elle peut également être sous forme d'un produit à base de cires thermofusibles ou d'un gel, qui est coulé à l'état chaud. Selon le type de composition choisi, la solidification se fait donc, soit par évaporation d'eau ou de solvant, soit par refroidissement, soit par réaction chimique.The liquefied makeup product can be presented in the form of a paste, obtained by mixing a solid particulate phase, either with an aqueous phase or with a binder, in particular a fatty phase in a solvent; she can also be in the form of a product based on hot-melt waxes or a gel, which is poured in the hot state. Depending on the type of composition chosen, the solidification is therefore done, either by evaporation of water or solvent, or by cooling, either by chemical reaction.

Il est connu de couler un produit de maquillage liquéfié dans un moule en volume, ce moule comportant une surface de moulage qui donne la forme au produit (plate, bombée ou munie de figures en relief ou en creux), à la surface destinée au prélèvement du produit, et un fond, muni d'un ou plusieurs orifices de remplissage, par lesquels on coule le produit.It is known to pour a liquefied makeup product into a mold by volume, this mold having a molding surface which gives the shape to the product (flat, curved or provided with raised or hollow figures), with the intended surface when the product is sampled, and a bottom fitted with one or more orifices for filling, by which the product is poured.

Ainsi, par le document EP-A-0 628 393 au nom de la demanderesse, on connaít un boítier pour la fabrication et la présentation d'un produit solide et délitable, ce boítier étant utilisé comme moule pour le coulage du produit liquéfié. Selon ce document, le boítier est constitué d'un fond, munie d'un bord circulaire et d'un couvercle bombé qui se visse sur le bord du fond. Ce fond est muni d'un orifice de remplissage. Le coté interne du fond est pourvu d'une rondelle en mousse alvéolaire. Pour le remplissage de ce boítier, ce dernier est retourné, de sorte qu'il repose sur son couvercle. Le produit liquéfié peut alors être coulé, au travers de l'orifice de remplissage et le centre de la rondelle, dans le volume défini entre le couvercle et le fond. Le produit liquéfié pénètre en partie dans la rondelle en mousse, où il reste accroché après solidification.Thus, by document EP-A-0 628 393 in the name of the applicant, we know a case for the manufacture and presentation of a solid and breakable product, this housing being used as a mold for pouring the liquefied product. According to what document, the case consists of a bottom, provided with a circular edge and a domed cover which screws onto the bottom edge. This bottom is provided with an orifice filling. The internal side of the bottom is provided with a foam washer alveolar. For the filling of this box, the latter is returned, so let it rest on its cover. The liquefied product can then be poured through of the filling orifice and the center of the washer, in the volume defined between the cover and the bottom. The liquefied product partially penetrates the washer foam, where it remains attached after solidification.

La demanderesse a constaté qu'il était préférable, notamment pour des raisons d'étanchéité et dans le souci de garantir un état de surface parfaitement lisse, d'intercaler, entre le couvercle et le produit, un opercule thermoformé, de sorte que ce dernier constitue la base du moule, lors du coulage du produit. En outre, un tel opercule peut être utilisé comme indicateur de non-violation du produit, ce qui est intéressant, notamment, lorsque le boítier est exposé sur les rayons d'un supermarché.The Applicant has found it preferable, in particular for reasons sealing and in order to guarantee a perfectly smooth surface condition, to insert, between the cover and the product, a thermoformed cover, so that the latter constitutes the base of the mold, during the casting of the product. In addition, such a seal can be used as an indicator of non-violation of the product, this which is interesting, in particular, when the case is exposed on the shelves of a supermarket.

Les essais effectués par la demanderesse ont montré que, lorsque l'utilisatrice, en vue d'effectuer un maquillage, enlève un tel opercule par simple traction, une partie du produit restait accrochée à l'opercule, rendant la surface de prélèvement du produit inesthétique et friable. The tests carried out by the applicant have shown that, when the user, in order to make up, remove such a seal by simple pulling, a part of the product remained attached to the lid, making the surface of unsightly and brittle product removal.

La demanderesse a cherché à remédier à cet inconvénient. De façon inattendue, elle a constaté qu'en soulevant l'opercule, après lui avoir subi un mouvement de rotation, le produit solide gardait une surface de prélèvement lisse et non friable. Afin d'éviter le soulèvement vertical de l'opercule par l'utilisatrice, la demanderesse a cherché à réaliser un mécanisme permettant de donner automatiquement une légère rotation à l'opercule lors de l'ouverture du boítier. En quelque sorte, la séparation du produit et de l'opercule doit être effectuée par cisaillement.The Applicant has sought to remedy this drawback. Unexpectedly, she found that by lifting the cover, after having undergone a movement of rotation, the solid product kept a smooth and non-friable sampling surface. In order to avoid vertical lifting of the cover by the user, the plaintiff sought to provide a mechanism for giving automatically a slight rotation at the lid when opening the case. In somehow, the separation of the product and the seal must be done by shear.

Ce but est atteint en accouplant temporairement l'opercule au couvercle, de sorte que ce denier, lors de son dévissage, entraíne l'opercule en rotation, par exemple sur un ¼ ou un ½ tour.This goal is achieved by temporarily coupling the lid to the cover, so that the latter, when it is unscrewed, causes the cover to rotate, for example on a ¼ or ½ turn.

Aussi, la présente invention a pour objet un boítier pour le conditionnement d'un produit sous forme de bloc solide ou semi-solide comprenant : - un fond définissant un réceptacle pour le bloc solide, des moyens d'accrochage du produit étant prévus pour immobiliser le bloc à l'intérieur du réceptacle, - un opercule disposé de manière amovible sur une surface du produit de manière à enfermer le bloc dans le réceptacle, et - un couvercle monté de manière amovible sur le fond de manière à sélectivement ouvrir/fermer le boítier. Selon l'invention, ce boítier comprend, en outre, des moyens de couplage entre le couvercle et l'opercule de sorte que l'ouverture du boítier par rotation du couvercle par rapport au fond, provoque, sur un angle donné, une rotation de l'opercule par rapport au produit, induisant ainsi un effet de cisaillement entre la surface interne de l'opercule et la surface du produit.Also, the present invention relates to a housing for the packaging of a product in the form of a solid or semi-solid block comprising: - a base defining a receptacle for the solid block, means for hooking the product being provided to immobilize the block inside the receptacle, - a lid removably arranged on a surface of the product so as to enclose the block in the receptacle, and - a cover removably mounted on the bottom so as to selectively open / close the housing. According to the invention, this housing further comprises coupling means between the cover and the cover so that the opening of the housing by rotation of the cover relative at the bottom, causes, on a given angle, a rotation of the cover relative to the product, thus inducing a shearing effect between the internal surface of the seal and the surface of the product.

Par l'expression « produit sous forme de bloc solide ou semi-solide » en entend tout produit délitable dont la consistance ne lui permet pas de s'écouler sous l'effet de son propre poids.The expression "product in the form of a solid or semi-solid block" means any crumbly product whose consistency does not allow it to flow under the effect of its own weight.

Avantageusement, le fond est muni d'un bord cylindrique et d'un filetage externe, un orifice de remplissage du produit étant prévu, traversant le fond et lesdits moyens d'accrochage, l'opercule prenant appui contre le bord cylindrique. De manière avantageuse, le couvercle est apte à se fixer, par exemple par vissage, sur le bord du fond. Selon un aspect intéressant de l'invention, les moyens de couplage comportent un ou plusieurs organes d'entraínement, portés par l'opercule, coopérant avec un ou plusieurs organes complémentaires portés par la surface interne du couvercle, un mouvement de rotation du couvercle par rapport au fond, lors de l'ouverture du boítier, provoquant une mise en engagement de l'organe d'entraínement et de l'organe complémentaire, entraínant alors en rotation l'opercule par rapport au produit.Advantageously, the bottom is provided with a cylindrical edge and an external thread, a product filling orifice being provided, passing through the bottom and said attachment means, the cover bearing against the cylindrical edge. Of advantageously, the cover is able to be fixed, for example by screwing, on the bottom edge. According to an interesting aspect of the invention, the means of coupling include one or more drive members, carried by the cover, cooperating with one or more complementary bodies carried by the inner surface of the cover, a movement of rotation of the cover by report to the bottom, when opening the case, causing a setting commitment of the training body and the complementary body, then causing the cover to rotate relative to the product.

En particulier, les moyens de couplage peuvent comporter une ou plusieurs encoches disposées sur un bord périphérique de l'opercule, et destinées à coopérer avec un ou plusieurs crans disposés sur la périphérie interne du couvercle, la rotation du couvercle par rapport au fond provoquant la mise en engagement de l'une des encoches avec l'un des crans. In particular, the coupling means may include one or more notches arranged on a peripheral edge of the cover, and intended to cooperate with one or more notches arranged on the internal periphery of the cover, the rotation of the cover relative to the bottom causing the setting engagement of one of the notches with one of the notches.

Il est possible, cependant, de disposer les organes d'entraínement sur un endroit quelconque de l'opercule, à condition que cet endroit se trouve en vis-à-vis du couvercle. Dans ce cas, le couvercle porte des organes complémentaires coopérant avec les organes d'entraínement de l'opercule.It is possible, however, to arrange the drives on a place any of the cover, provided that this place is opposite the lid. In this case, the cover carries complementary members cooperating with the drive members of the cover.

Lorsque plusieurs encoches et plusieurs crans sont prévus, ceux-ci sont repartis, avantageusement, de manière régulière, sur l'opercule et le couvercle respectivement. Le nombre des encoches peut être égal au nombre des crans. Cependant, il est avantageux de prévoir un nombre d'encoches différent d'au moins une unité du nombre de crans. Par cette disposition, l'angle suivant lequel un cran s'engage dans une encoche peut être considérablement réduit.When several notches and several notches are provided, these are distributed, advantageously, on a regular basis, on the cover and the cover respectively. The number of notches can be equal to the number of notches. However, it is advantageous to provide a number of notches different from at least minus one unit of the number of notches. By this arrangement, the angle from which a notch engages in a notch can be considerably reduced.

Selon un mode de réalisation particulier, le bord périphérique de l'opercule comporte n encoches reparties de manière régulière sur le bord périphérique de l'opercule et disposées en vis-à-vis de n-1 crans repartis de manière régulière sur la surface interne du couvercle, n étant au moins égal à 2. De manière générale, l'engagement d'un cran dans une encoche est d'autant plus rapide à atteindre que le nombre d'encoches et de crans sur l'opercule et le couvercle respectivement, est élevé.According to a particular embodiment, the peripheral edge of the cover has n notches distributed evenly on the peripheral edge of the cover and arranged opposite n-1 notches distributed regularly over the internal surface of the cover, n being at least equal to 2. In general, engaging a notch in a notch is all the faster to achieve that the number of notches and notches on the lid and the cover respectively, is high.

De manière avantageuse, le nombre n est égal ou supérieur à 6. Plus particulièrement, par exemple avec un nombre n d'encoches égal à 13 et un nombre de crans n-1 égal à 12, on obtient l'engagement d'un cran dans une encoche au bout d'un angle de rotation maximum du couvercle, par rapport au fond, égal ou inférieur à 2°4'.Advantageously, the number n is equal to or greater than 6. More particularly, for example with a number n of notches equal to 13 and a number of notches n-1 equal to 12, we obtain the engagement of a notch in a notch at the end of a maximum angle of rotation of the cover, relative to the background, equal to or less than 2 ° 4 '.

Avantageusement, les moyens d'accrochage sont constitués par une plaque annulaire en mousse alvéolaire à cellules ouvertes. De préférence, on utilise une plaque de mousse élastiquement déformable. Cette plaque de mousse sert de support pour le produit, ce qui est particulièrement avantageux lorsque le produit présente un rétreint important lors de sa solidification. En effet, lors du coulage du produit, ce dernier pénètre partiellement dans les cellules où il se solidifie sans fragilisation du pain moulé, comme indiqué dans le document EP-A-O 628 393 précité. La plaque de mousse peut être rendue solidaire du fond, soit par calage, soit par collage, soit par thermosoudage.Advantageously, the attachment means consist of a plate ring-shaped open cell foam. Preferably, a elastically deformable foam plate. This foam plate serves as support for the product, which is particularly advantageous when the product exhibits significant shrinkage during solidification. Indeed, when pouring the product, the latter partially penetrates into the cells where it solidifies without embrittlement of molded bread, as indicated in document EP-A-O 628 393 cited above. The foam plate can be made integral with the bottom, either by wedging, either by gluing or by heat sealing.

Il est bien entendu, que les moyens d'accrochage peuvent être constitués par tout autre moyen d'ancrage, par exemple des pattes, portées par la platine, pénétrant dans le produit solidifié, ce qui est possible pour tout produit ne présentant pas ou peu de rétreint, lors de sa solidification.It is understood that the attachment means can be constituted by any other anchoring means, for example legs, carried by the plate, entering the solidified product, which is possible for any product with little or no shrinkage during solidification.

Selon une forme de réalisation préférée, le bord cylindrique du fond présente une extrémité libre sur laquelle est posé l'opercule. Cet opercule présente un axe de révolution confondu avec l'axe du boítier.According to a preferred embodiment, the cylindrical edge of the bottom has a free end on which the cover is placed. This cover has an axis of revolution confused with the axis of the case.

Avantageusement, cet opercule présente une jupe périphérique, faisant étanchéité avec l'extrémité libre du bord cylindrique du fond. L'opercule peut présenter une forme bombée, concave, par exemple une forme de calotte, la concavité de l'opercule étant tournée vers l'extérieur du boítier. Toute autre forme présentant un axe de rotation peut convenir également. Par cette disposition, l'opercule, la plaque de mousse et la platine définissent un volume, destiné à recevoir le produit. Ainsi, ces pièces forment un « moule », dans lequel le produit peut être déposé par coulage.Advantageously, this cover has a peripheral skirt, making sealing with the free end of the cylindrical edge of the bottom. The seal can have a domed, concave shape, for example a cap shape, the concavity of the cover being turned towards the outside of the case. Any other form having an axis of rotation may also be suitable. By this provision, the cover, the foam plate and the plate define a volume, intended for receive the product. Thus, these parts form a "mold", in which the product can be deposited by casting.

Dans cette configuration, le produit doit être liquéfiable, apte à être mis en place dans le « moule » par coulage au travers de l'orifice de remplissage et au travers du centre ouvert de la rondelle en mousse, et à se solidifier dans le volume après le coulage. Pour couler le produit liquéfié, on retourne le boítier, de sorte que l'orifice de remplissage devienne accessible. On remplit alors le « moule » complètement, en prenant soin de noyer la rondelle de mousse dans le produit. Après solidification du produit, l'orifice de remplissage de la platine peut être obturé par un bouchon.In this configuration, the product must be liquefiable, capable of being put in place in the "mold" by pouring through the filling orifice and through from the open center of the foam washer, and to solidify in volume after pouring. To pour the liquefied product, we turn the case over, so that the filling opening becomes accessible. We then fill the "mold" completely, taking care to drown the foam ring in the product. After solidification of the product, the filling orifice of the plate can be closed by a plug.

Selon une forme de mise en oeuvre préférée de l'invention, le produit à couler contient, outre des pigments colorés, de charges et de liants, du sulfate de calcium hemihydrate (CaSO4, ½ H2O) et une quantité suffisante d'eau pour obtenir un mélange coulable, la solidification se produisant, après coulage dans le boítier, par formation de sulfate de calcium dihydrate (CaSO4, 2H2O). Le cas échéant, le mélange coulable peut contenir un agent modificateur du temps de prise du sulfate de calcium hemihydrate.According to a preferred embodiment of the invention, the product to be cast contains, in addition to colored pigments, fillers and binders, calcium sulfate hemihydrate (CaSO 4 , ½ H 2 O) and a sufficient amount of water to obtain a flowable mixture, solidification occurring, after pouring into the housing, by formation of calcium sulfate dihydrate (CaSO 4 , 2H 2 O). If necessary, the pourable mixture may contain an agent which modifies the setting time of the calcium sulphate hemihydrate.

Cependant, il est possible de mettre en oeuvre des produits se liquéfiant à température élevée, et se solidifiant après refroidissement. Il est envisageable, également, de couler une dispersion de pigments dans un solvant, la solidification du produit étant obtenue par évaporation du solvant.However, it is possible to use products which liquefy at high temperature, and solidifies after cooling. It is possible, also, to pour a dispersion of pigments in a solvent, solidification of the product being obtained by evaporation of the solvent.

Selon un aspect intéressant de l'invention, le couvercle et l'opercule sont transparents. Cette disposition présente l'avantage que le produit est visible de l'extérieur, le boítier ayant ainsi une fonction de présentoir. A cet effet, le couvercle peut être moulé en un matériau transparent tel que le polystyrène. L'opercule, quant à lui, peut être obtenu par thermoformage d'une feuille transparente, réalisée en un matériau tel que le PVC (chlorure de polyvinyle), le polypropylène, le polycarbonate, le polystyrène, le polyéthylène téréphthalate, etc..According to an interesting aspect of the invention, the cover and the lid are transparent. This arrangement has the advantage that the product is visible from the exterior, the housing thus having a display function. To this end, the cover can be molded from a transparent material such as polystyrene. The cover, on the other hand, can be obtained by thermoforming a sheet transparent, made of a material such as PVC (polyvinyl chloride), polypropylene, polycarbonate, polystyrene, polyethylene terephthalate, etc.

Pour assurer la fixation de l'opercule sur le bord cylindrique du fond, avantageusement, le couvercle est pourvu d'une saillie interne, apte à s'appliquer contre la face opposée à la partie de l'opercule qui est en contact avec l'extrémité libre du bord cylindrique du fond. A son tour, le couvercle, muni d'un filetage interne, peut se fixer, de façon réversible, par vissage, sur le filetage externe du fond. Ainsi, l'opercule est pris en sandwich entre le couvercle et le fond.To secure the cover on the cylindrical edge of the bottom, advantageously, the cover is provided with an internal projection, suitable for being applied against the face opposite to the part of the cover which is in contact with the end free from the bottom cylindrical edge. In turn, the cover, provided with a thread internal, can be fixed, reversibly, by screwing, on the external thread of the background. Thus, the cover is sandwiched between the cover and the bottom.

Pour effectuer un maquillage, il suffit de dévisser le couvercle. Conformément à l'invention, le dévissage du couvercle entraíne en rotation l'opercule suivant l'angle de rotation décrit précédemment. Lors du dévissage du couvercle, très rapidement un cran s'engage dans une encoche et entraíne l'opercule en rotation. En même temps, le couvercle exécute une montée suivant l'axe du boítier, provoquant, après avoir parcouru un angle compris, par exemple, entre environ 10° et environ 180°, le désengagement de l'encoche et du cran concerné. De préférence cet angle est compris entre 90° et 180°. Sa valeur peut être réglée en fonction de la hauteur du pas de vis réalisé sur le couvercle et le fond respectivement, ainsi que de la hauteur du cran. Ensuite, il suffit de deviser complètement le couvercle et de retirer l'opercule par simple traction.To make up, simply unscrew the cover. In accordance with the invention, unscrewing the cover rotates the following cover the angle of rotation described above. When unscrewing the cover, very quickly a notch engages in a notch and drives the seal in rotation. At the same time, the cover rises along the axis of the housing, causing, after having traversed an angle included, for example, between approximately 10 ° and approximately 180 °, the disengagement of the notch and the notch concerned. Preferably this angle is between 90 ° and 180 °. Its value can be adjusted depending on the height of the thread on the cover and the bottom respectively, as well as the notch height. Then just talk the cover completely and remove the cover by simple pull.

L'opercule et le produit solide étant séparés ainsi par un mouvement relatif de cisaillement, la surface d'application est lisse et ne porte pas de traces d'effritement.The cover and the solid product being thus separated by a relative movement of shear, the application surface is smooth and does not show marks crumbling.

Avantageusement, le produit conditionné dans le boítier est un fard à joues, une ombre à paupières ou un fond de teint.Advantageously, the product packaged in the case is a blush, a eye shadow or foundation.

Pour mieux faire comprendre la présente invention, on va décrire maintenant, à titre d'exemple purement illustratif et nullement limitatif, un mode de réalisation d'un boítier conforme à l'invention, en référence aux dessins annexés.To better understand the present invention, we will now describe, at purely illustrative and in no way limitative, an embodiment of a housing according to the invention, with reference to the accompanying drawings.

La figure 1 représente une coupe axiale du boítier de l'invention muni d'un opercule.Figure 1 shows an axial section of the housing of the invention provided with a operculum.

La figure 2 représente une coupe axiale de l'opercule du boítier de la figure 1.2 shows an axial section of the cover of the housing of Figure 1.

La figure 3 représente une vue de dessus de l'opercule du boítier de la figure 1, selon la direction III-III de la figure 2.FIG. 3 represents a top view of the cover of the box of FIG. 1, in the direction III-III of Figure 2.

La figure 4 représente une coupe axiale du couvercle de boítier de la figure 1.FIG. 4 represents an axial section of the housing cover of FIG. 1.

La figure 5 représente une vue de dessus de la platine de boítier de la figure 1, selon la direction V-V de cette figure.FIG. 5 represents a top view of the box plate of FIG. 1, in the direction V-V of this figure.

En référence à ces figures, notamment à la figure 1, on voit qu'on a désigné l'ensemble d'un boítier de maquillage par la référence 1. Le boítier contient un fard à joues P solide, délitable. Ce boítier présente un axe de rotation A et se compose d'un fond 2 définissant un réceptacle, surmonté d'un couvercle transparent 4, un opercule transparent 6, d'une rondelle en mousse alvéolaire 8 est d'un bouchon 10.With reference to these figures, in particular to Figure 1, we see that we have designated the whole of a make-up case by the reference 1. The case contains a blush P solid, crumbly. This case has an axis of rotation A and is consists of a bottom 2 defining a receptacle, surmounted by a cover transparent 4, a transparent cover 6, of a cellular foam washer 8 is a plug 10.

Le fond 2 présente une structure annulaire et comporte une embase 12 munie d'une large ouverture centrale 14 dans laquelle est inséré le bouchon 10.The bottom 2 has an annular structure and has a base 12 provided a large central opening 14 into which the plug 10 is inserted.

Du côté du fond, l'embase 12 présente une périphérie 13 de forme arrondie, sensiblement en quart de cercle. Du coté opposé au fond 12, l'embase porte une courte portion cylindrique 16, de diamètre plus faible que celui de l'embase 12, cette portion 16 étant pourvue d'un filetage externe 18 servant à la fixation du couvercle 4. A la portion 16 est raccordée une jupe cylindrique 20 dont le diamètre est plus faible que celui de la portion 16, formant un décrochement interne 22. La jupe 20 présente une extrémité libre formant un bord cylindrique 24, en contact avec l'opercule 6.On the bottom side, the base 12 has a periphery 13 of rounded shape, substantially in a quarter circle. On the opposite side to the bottom 12, the base carries a short cylindrical portion 16, of smaller diameter than that of the base 12, this portion 16 being provided with an external thread 18 used for fixing the cover 4. To the portion 16 is connected a cylindrical skirt 20, the diameter is smaller than that of portion 16, forming a step internal 22. The skirt 20 has a free end forming a cylindrical edge 24, in contact with the cover 6.

Cet opercule 6 est réalisé par thermoformage, notamment à partir d'une feuille en PVC transparent. Il est possible, également de le réaliser en polypropylène, polycarbonate, polystyrène, polyéthylène téréphthalate, etc..This cover 6 is produced by thermoforming, in particular from a sheet of Transparent PVC. It is also possible to make it out of polypropylene, polycarbonate, polystyrene, polyethylene terephthalate, etc.

Comme visible sur les figures 2 et 3, l'opercule 6 comporte une partie centrale 26 sous forme de calotte bombée, raccordée à un plateau annulaire 28, dont la largeur correspond sensiblement à la largeur du bord 24. Le plateau 28 est replié d'équerre pour former une courte partie cylindrique 30, elle-même repliée radialement vers l'extérieur pour former une bordure annulaire 32. La partie cylindrique s'applique à friction contre la paroi externe de la jupe 20. La bordure 32 comporte un certain nombre n d'encoches (34), espacées régulièrement sur sa périphérie. Typiquement n est égal ou supérieur à 2, de préférence supérieur ou égal à 6. Dans le mode de réalisation illustré, la bordure 32 est interrompue par 13 créneaux 34, régulièrement repartis sur cette bordure (voir figure 3). Chaque créneau 34 se trouve espacé d'un angle α de 27,7° par rapport un créneau voisin. La largeur de chaque créneau 34 est symbolisée par la référence d1 (voir figure 3).As shown in Figures 2 and 3, the cover 6 has a central portion 26 in the form of a domed cap, connected to an annular plate 28, the width of which corresponds substantially to the width of the edge 24. The plate 28 is folded angle to form a short cylindrical part 30, itself folded radially outwards to form an annular border 32. The cylindrical part is applied frictionally against the external wall of the skirt 20. The border 32 has a number n notches (34), regularly spaced around its periphery. Typically n is equal to or greater than 2, preferably greater than or equal to 6. In the illustrated embodiment, the border 32 is interrupted by 13 slots 34, regularly distributed over this border (see FIG. 3). Each slot 34 is spaced at an angle α of 27.7 ° relative to a neighboring slot. The width of each slot 34 is symbolized by the reference d 1 (see FIG. 3).

Selon un autre mode de réalisation non représenté, les moyens de couplage comportent un certain nombre de reliefs disposés sur la surface externe de l'opercule, destinés à coopérer avec des reliefs complémentaires portés par la surface interne du couvercle. De tels reliefs peuvent être situés, par exemple, autour du centre de l'opercule, ou ailleurs encore, entre l'axe et la périphérie.According to another embodiment not shown, the coupling means have a number of reliefs arranged on the external surface of the cover, intended to cooperate with complementary reliefs carried by the inner surface of the cover. Such reliefs can be located, for example, around the center of the cover, or elsewhere, between the axis and the periphery.

A l'intérieur du réceptacle 2 est placée la rondelle 8. Elle comporte une ouverture centrale 36. L'ouverture du fond 14 et l'ouverture 36 de la rondelle 8 constituent, selon ce mode de réalisation, un orifice de remplissage du produit P. La rondelle 8 s'étend radialement jusqu'à la portion cylindrique 16 et est maintenue sous le décrochement 22 où elle est fixée par soudage thermique. La rondelle 8 est réalisée en mousse alvéolaire à cellules ouvertes, par exemple en mousse de polyéthylène, élastiquement compressible. Elle constitue les moyens d'accrochage du bloc de produit P. Elle peut être rendue solidaire du fond 2 par collage, également ou par tout autre moyen adapté.Inside the receptacle 2 is placed the washer 8. It has an opening central 36. The opening of the bottom 14 and the opening 36 of the washer 8 constitute, according to this embodiment, a filling orifice for the product P. The washer 8 extends radially to the cylindrical portion 16 and is held under the recess 22 where it is fixed by thermal welding. Washer 8 is made of open-cell alveolar foam, for example polyethylene, elastically compressible. It constitutes the means for hanging the product block P. It can be secured to the bottom 2 by bonding, also or by any other suitable means.

Le couvercle 4 (voir notamment les figures 4 et 5) est conformé en calotte, de dimension suffisante pour être posé au-dessus de l'opercule 6. Il est moulé en un matériau, de préférence, transparent. On peut utiliser, par exemple du polystyrène. ll présente un flanc cylindrique 38, pourvu à l'intérieur d'un filetage, apte à coopérer avec le filetage 18 du fond 2. Le couvercle 4 présente, en outre, une saillie interne 42 annulaire, apte à venir en appui contre le plateau annulaire 28 de l'opercule 6, afin d'immobiliser ce dernier, lorsque le couvercle est fixé sur le fond 2. Sur un pourtour interne 44 de la paroi du couvercle, situé entre la saillie 42 et le filetage 40, sont régulièrement repartis des crans 46, destinés à s'engager dans les encoches de l'opercule 6. Typiquement, pour un nombre n d'encoches (n ≥ 2) sur l'opercule, on prévoit un certain nombre de crans sur le couvercle. Avantageusement, le nombre de crans diffère d'au moins une unité du nombre des encoches. Dans le mode de réalisation illustré à la figure 5, on prévoit 12 crans. Chaque cran 42 présente une largeur d2 inférieure à la largeur d1 des créneaux 34. Les crans 46 présentent une hauteur d3 (voir figure 4) suffisante pour s'appuyer, en position de fermeture du boítier, sur la bordure 32 de l'opercule 6.The cover 4 (see in particular Figures 4 and 5) is shaped into a cap, of sufficient size to be placed above the cover 6. It is molded from a material, preferably transparent. It is possible to use, for example polystyrene. It has a cylindrical flank 38, provided inside with a thread, capable of cooperating with the thread 18 of the bottom 2. The cover 4 has, moreover, an internal annular projection 42, capable of coming to bear against the plate annular 28 of the cover 6, in order to immobilize the latter, when the cover is fixed on the bottom 2. On an internal periphery 44 of the wall of the cover, located between the projection 42 and the thread 40, are regularly distributed from the notches 46, intended to engage in the notches of the cover 6. Typically, for a number n of notches (n ≥ 2) on the cover, a number of notches are provided on the cover. Advantageously, the number of notches differs by at least one unit from the number of notches. In the embodiment illustrated in FIG. 5, 12 notches are provided. Each notch 42 has a width d 2 less than the width d 1 of the slots 34. The notches 46 have a height d 3 (see Figure 4) sufficient to rest, in the closed position of the housing, on the edge 32 of the '' cover 6.

La rondelle 8, la jupe 20 et l'opercule 6 définissent un volume déterminé, apte à recevoir, par coulage par exemple, une quantité appropriée de produit P à l'état liquéfié. Pour effectuer ce coulage, on assemble le fond 2 muni de la rondelle en mousse 8 avec l'opercule 6. La partie cylindrique de l'opercule 6 est engagé à friction sur la jupe 20 du fond 2. Cet ensemble est posé, opercule en bas, de sorte que l'orifice de remplissage 14, 36 soit accessible. On coule alors une quantité de produit P à l'état liquide, suffisante pour noyer la rondelle 8 dans le produit. Après solidification du produit, l'ouverture 14 du fond 2 est fermée par le bouchon 10 et le couvercle est fixé, par vissage sur le filetage 18 du fond. Du fait de la transparence de l'opercule 6 et du couvercle 4, l'utilisatrice peut vérifier, d'un seul coup d'oeil, la couleur du produit P.The washer 8, the skirt 20 and the cover 6 define a determined volume, suitable for receive, by pouring for example, an appropriate quantity of product P in the state liquefied. To carry out this pouring, the bottom 2 is fitted with the washer in foam 8 with the cover 6. The cylindrical part of the cover 6 is engaged at friction on the skirt 20 of the bottom 2. This assembly is placed, covers at the bottom, so that the filling orifice 14, 36 is accessible. We then pour a quantity of product P in the liquid state, sufficient to drown the washer 8 in the product. After solidification of the product, the opening 14 of the bottom 2 is closed by the plug 10 and the cover is fixed, by screwing on the thread 18 of the bottom. Because the transparency of the cover 6 and the cover 4, the user can check, at a glance, the color of the product P.

Pour effectuer un maquillage, l'utilisatrice enlève le couvercle 4 par vissage. Lors de la rotation du couvercle par rapport au fond, très rapidement, c'est-à-dire au bout d'un angle de rotation inférieur à 2°4', dans le cas de la configuration détaillée ci-avant, l'un des crans 46 s'engage dans l'un des créneaux 34. Lorsque l'utilisatrice continue le dévissage, le couvercle 4 entraíne l'opercule 6 en rotation. Lors de la rotation de l'opercule, celui-ci se désolidarise du produit solide P par cisaillement. En même temps, le couvercle 4 s'éloigne axialement du fond 2, de sorte qu'au bout d'un ¼ ou d'un ½ tour de dévissage, le cran 46 se désengage du créneau 34. A ce stade l'opercule 6 est toujours solidaire du fond 2. Après dévissage complet du couvercle 4, l'utilisatrice peut soulever l'opercule 6 par simple traction, sans provoquer de détérioration de la surface de prélèvement 48 (figure 1) du produit P.To make up, the user removes the cover 4 by screwing. When of the rotation of the cover relative to the bottom, very quickly, that is to say end of a rotation angle less than 2 ° 4 ', in the case of the configuration detailed above, one of the notches 46 engages in one of the slots 34. When the user continues unscrewing, the cover 4 drives the cover 6 in rotation. When the lid is rotated, it separates from the solid product P by shear. At the same time, the cover 4 moves axially away from the bottom 2, so that after a ¼ or ½ unscrewing turn, the notch 46 disengages from the slot 34. At this stage the cover 6 is always secured to the bottom 2. After completely unscrewing the cover 4, the user can lift the cover 6 by simple pull, without causing damage to the sampling surface 48 (figure 1) of product P.

L'utilisation d'un opercule 6 pour mouler la surface de prélèvement 48 du boítier présente plusieurs avantages : grâce à la présence de l'opercule 6 lors du coulage du produit liquéfié, on évite le colmatage des filetages 18 et 40, car l'étanchéité du volume de produit se fait au niveau du plateau 24 de la platine et la partie cylindrique 30 de l'opercule. En outre, sans être obligé de changer la forme du fond 2, de la rondelle 8 et du couvercle 4, il est possible de modifier la forme de la surface de prélèvement 48. Ainsi, la surface 48 peut présenter une forme plate, conique, à bourrelets annulaires concentriques, etc.. En effet, il est possible de réaliser toute forme de l'opercule, à condition que cette forme présente un axe de rotation A. La réalisation d'un tel opercule 6, par thermoformage, est avantageuse du point de vue économique.The use of a cover 6 for molding the sampling surface 48 of the housing has several advantages: thanks to the presence of the seal 6 during the pouring the liquefied product, avoiding clogging of the threads 18 and 40, because the volume of the product is sealed at the level of the plate 24 of the plate and the cylindrical part 30 of the cover. In addition, without having to change the shape of the bottom 2, of the washer 8 and of the cover 4, it is possible to modify the shape of the sampling surface 48. Thus, the surface 48 may have a flat, conical shape, with concentric annular beads, etc. Indeed, it is possible to form any form of the cover, provided that this form has an axis of rotation A. The production of such a cover 6, by thermoforming, is advantageous from the economic point of view.
