Description

La présente invention a pour objet un dispositif de conditionnement d'un produit contenu dans un récipient, ce récipient étant présenté dans une coque externe. De préférence, l'invention permet un conditionnement esthétique d'un produit cosmétique, la coque externe étant choisie de manière à définir l'esthétique du dispositif de conditionnement, tandis que le récipient disposé dans la coque externe garantit des conditions de stockage optimale du produit.The present invention relates to a device for packaging a product contained in a container, this container being presented in an outer shell. Preferably, the invention allows cosmetic packaging of a cosmetic product, the outer shell being chosen so as to define the aesthetics of the packaging device, while the container disposed in the outer shell ensures optimal storage conditions of the product .

Par « produit cosmétique », on entend un produit tel que défini dans la Directive 93/35/CEE du Conseil du 14 juin 1993."Cosmetic product" means a product as defined in Council Directive 93/35 / EEC of 14 June 1993.

Dans l'état de la technique, on connaît des dispositifs de conditionnement dont l'esthétique de l'aspect extérieur est conférée par une coque externe, notamment on connaît de tels dispositifs des documents US-3871543 et FR-2715354 .In the state of the art, there are known packaging devices whose aesthetics of the external appearance is conferred by an outer shell, in particular such devices are known documents US 3871543 and FR-2715354 .

Le document US-3871543 décrit un récipient retenu dans une coque externe, le récipient comportant sur son pourtour extérieur une nervure destinée à coopérer par encliquetage avec un relief complémentaire dépassant du pourtour intérieur d'une paroi latérale de la coque externe.The document US 3871543 discloses a container retained in an outer shell, the container having on its outer periphery a rib for cooperating by snapping with a complementary relief protruding from the inner periphery of a side wall of the outer shell.

Le document FR-2715384 décrit un dispositif de conditionnement comportant un récipient monté de manière amovible dans une coque externe en forme d'hémisphère tronquée, le couvercle prévu pour obturer le récipient ayant une forme complémentaire d'hémisphère. Le récipient présente deux pattes diamétralement opposées à indexer relativement à deux encoches formées dans le pourtour extérieur du col de la coque externe, col avec lequel le couvercle coopère.The document FR-2715384 discloses a packaging device comprising a container removably mounted in an outer shell shaped truncated hemisphere, the cover provided to close the container having a hemisphere complementary shape. The container has two diametrically opposed tabs to index relative to two notches formed in the outer periphery of the neck of the outer shell, neck with which the lid cooperates.

Le document US-5590782 décrit un dispositif de conditionnement selon le préambule de la revendication 1.The document US 5590782 discloses a packaging device according to the preamble of claim 1.

L'invention a pour objet de proposer un dispositif qui soit peu cher à réaliser, facile à assembler et permettant une accroche solide entre la coque externe et le récipient, tout en ne nuisant pas à l'esthétique du dispositif de conditionnement.
L'invention a pour objet un dispositif de conditionnement d'un produit selon la revendication 1, et comportant une coque externe, un récipient formant au moins un logement apte à recevoir le produit, ce récipient étant retenu à l'intérieur de la coque externe, et un organe de fermeture apte à être retenu sur le récipient pour obturer ce dernier, caractérisé en ce que la coque externe comporte une fenêtre traversante formée au travers d'un col de la coque externe dans laquelle vient s'engager un décrochement latéral extérieur du récipient de manière à retenir le récipient dans la coque externe.The invention aims to provide a device that is inexpensive to achieve, easy to assemble and allowing a solid grip between the outer shell and the container, while not detracting from the aesthetics of the packaging device.
The invention relates to a device for packaging a product according to claim 1, and comprising an outer shell, a container forming at least one housing adapted to receive the product, this container being retained inside the outer shell , and a closure member adapted to be retained on the container for closing the latter, characterized in that the outer shell comprises a through window formed through a neck of the outer shell in which is engaged an external lateral recess of the container so as to hold the container in the outer shell.

L'intérêt d'une telle solution est qu'elle permet de former une zone d'accroche peu épaisse entre le récipient et la coque externe. Ainsi l'épaisseur des parois de respectivement la coque externe et du récipient peut être limitée, et par ailleurs la distance radiale laissée entre la coque externe et le récipient peut également être limitée.The advantage of such a solution is that it makes it possible to form a thin zone of attachment between the container and the outer shell. Thus the thickness of the walls of the outer shell and the container respectively can be limited, and moreover the radial distance left between the outer shell and the container can also be limited.

Avantageusement, le décrochement peut être annulaire et le col définit alors une surface interne en retrait en dehors de la zone annulaire où est formée la fenêtre. Ainsi, il n'est pas nécessaire d'indexer la position du récipient relativement à celle que la coque externe lors de l'assemblage du récipient dans la coque externe.Advantageously, the recess may be annular and the neck then defines an internal surface recessed outside the annular zone where the window is formed. Thus, it is not necessary to index the position of the container relative to that the outer shell when assembling the container in the outer shell.

Le col peut être configuré de telle sorte que l'organe de fermeture comporte une jupe masquant ladite fenêtre en position assemblée sur le récipient. Ainsi l'esthétique du dispositif n'est pas affectée par les moyens d'accrochage prévus entre la coque externe et le récipient. De plus, même si des déformations, ou retassures, sont observées dans le col du fait de l'insertion du récipient dans la coque externe, ces déformations peuvent être masquées par ladite jupe.The neck may be configured such that the closure member has a skirt masking said window in the assembled position on the container. Thus the aesthetics of the device is not affected by the attachment means provided between the outer shell and the container. In addition, even if deformations, or sinkholes, are observed in the neck due to the insertion of the container into the outer shell, these deformations can be masked by said skirt.

Le col peut comporter au moins deux fenêtres radialement opposées. Dans ce cas, lors de l'insertion du récipient, le col se déforme dans les zones situées à distance des fenêtres. Dans le cas où le col est de section circulaire, il s'ovalise lors de l'insertion du récipient, la plus grande dimension de l'ovale d col étant donnée entre les fenêtres radialement opposées, jusqu'à ce que le décrochement vienne en engagement dans lesdites fenêtres.The neck may include at least two radially opposed windows. In this case, during the insertion of the container, the neck deforms in the areas located away from the windows. In the case where the neck is of circular section, it is ovalized during the insertion of the container, the largest dimension of the oval neck being given between the radially opposite windows, until the recess comes in engagement in said windows.

La coque externe peut être obtenue de moulage, et en particulier de moulage à partir d'un moule comportant des coquilles ou des tiroirs, en particulier au niveau du col. Ainsi, la précision des côtes de réalisation de la coque externe est forte, et les tolérances de fabrication peuvent être faibles.The outer shell may be obtained from molding, and in particular molding from a mold having shells or drawers, particularly at the neck. Thus, the accuracy of the ribs for producing the outer shell is high, and manufacturing tolerances can be low.

Avantageusement, le récipient peut aussi être obtenu de moulage. De préférence, il est également obtenu à partir d'un moule comportant des coquilles ou des tiroirs, notamment pour former le décrochement, de manière à ce que les tolérances de fabrication du récipient puissent être faibles également.Advantageously, the container may also be obtained by molding. Preferably, it is also obtained from a mold comprising shells or drawers, in particular to form the recess, so that the manufacturing tolerances of the container can also be low.

L'utilisation de moules à coquilles permet une géométrie des surfaces d'accrochage prévues entre la coque externe et le récipient, ces surfaces étant perpendiculaires ou sensiblement perpendiculaires à l'axe longitudinal, bien planes, d'orientation parfaitement définies et bien anguleuses à leur extrémité. Ainsi le décrochement et la fenêtre traversante présentent respectivement des surfaces d'accroche ayant la planéité, l'orientation et les arêtes marquées de manière à assurer une bonne accroche. L'utilisation de tels moules permet de pallier aux défauts conférés par un démoulage en force qui confère aux surfaces d'accrochage une orientation et une planéité incertaines, les arêtes de ces surfaces n'étant pas nettes mais rayonnées.The use of shell molds allows a geometry of the attachment surfaces provided between the outer shell and the container, these surfaces being perpendicular or substantially perpendicular to the longitudinal axis, well planar, orientation perfectly defined and well angular to their end. Thus the recess and the through window respectively have gripping surfaces having the flatness, orientation and sharp edges so as to ensure good grip. The use of such molds overcomes the defects imparted by a force release which gives the gripping surfaces orientation and flatness uncertain, the edges of these surfaces are not sharp but radiated.

Dans les cas où la précision de fabrication est forte, contrairement aux cas où les objets sont démoulés en force, alors les tolérances de montage et le jeu prévu entre les deux pièces à assembler peut être fortement réduit ce qui participe à un des objets de l'invention qui est de proposer un moyen d'accroche radialement peu épais. De plus la qualité de l'accroche formée entre la coque externe et le récipient peut aussi en être améliorée, dans la mesure où les faces de respectivement le décrochement du récipient et le pourtour de la fenêtre peuvent être amenées en contact direct, de telle sorte qu'elles s'étendent l'un contre l'autre selon un plan de contact sensiblement perpendiculaire à l'axe selon lequel le récipient est monté dans la coque externe.In cases where the manufacturing accuracy is high, unlike in cases where the objects are demolded in force, then the mounting tolerances and the expected clearance between the two parts to be assembled can be greatly reduced which contributes to one of the objects of the invention. invention which is to propose a means of attachment radially thin. In addition, the quality of the grip formed between the outer shell and the container can also be improved, insofar as the faces of respectively the recess of the container and the periphery of the window can be brought into direct contact, so that that they extend against each other in a contact plane substantially perpendicular to the axis in which the container is mounted in the outer shell.

La coque externe peut être réalisée dans un matériau transparent. En particulier, elle est réalisée à partir d'un matériau plastique. Le matériau utilisé peut être un polymère styrénique, tel que le polystyrène, les copolymères de styrène et de butadiène (SBS) ou les copolymères statistiques de styrène et d'acrylonitrile (SAN). Le matériau utilisé pour la réalisation de la coque externe peut aussi être un polymère de polyéthylène téréphtalate (PET) ou un polymère de polyéthylène naphtalate (PEN) ou un copolymère de ces deux polymères. Il peut aussi être réalisé à partir d'un polymère de cyclohexadiène téréphtalate glycol (PCTG) ou un polymère de polyamide.The outer shell can be made of a transparent material. In particular, it is made from a plastic material. The material used may be a styrenic polymer, such as polystyrene, styrene and butadiene copolymers (SBS) or random copolymers of styrene and acrylonitrile (SAN). The material used for producing the outer shell may also be a polyethylene terephthalate (PET) polymer or a polyethylene naphthalate (PEN) polymer or a copolymer of these two polymers. It can also be produced from a cyclohexadiene terephthalate glycol polymer (PCTG) or a polyamide polymer.

Pour réaliser la coque externe, tous les choix de matériaux sont possibles dans la mesure où il n'y a pas de contraintes à respecter en matière de compatibilité des matériaux de cette coque externe avec le produit contenu dans le récipient, ce dernier étant le seul au contact du produit.To achieve the outer shell, all material choices are possible insofar as there are no constraints to respect the compatibility of the materials of this outer shell with the product contained in the container, the latter being the only in contact with the product.

Le décrochement peut comporter une face dressée radialement au pourtour extérieur du récipient et une deuxième face formant une pente configurée pour faciliter l'insertion du récipient dans la coque externe, et respectivement faciliter le placement du décrochement dans la fenêtre. Selon un plan en coupe longitudinal selon un axe d'insertion du récipient dans la coque externe, le décrochement présente un profil en forme de harpon.The recess may comprise a face raised radially to the outer periphery of the container and a second face forming a slope configured to facilitate the insertion of the container into the outer shell, and respectively facilitate the placement of the recess in the window. According to a longitudinal sectional plane along an axis of insertion of the container into the outer shell, the recess has a profile in the form of a harpoon.

La fenêtre est de préférence formée au travers du col de telle sorte qu'elle s'étend au travers du col selon une direction sensiblement perpendiculaire à un axe d'insertion du récipient dans la coque externe. Au moins la face supérieure de cette fenêtre contre laquelle le décrochement vient en engagement s'étend selon un plan perpendiculaire à cet axe d'insertion.The window is preferably formed through the neck so that it extends through the neck in a direction substantially perpendicular to an axis of insertion of the container into the outer shell. At least the upper face of this window against which the recess comes into engagement extends in a plane perpendicular to this axis of insertion.

En dehors de la zone où est formée la fenêtre, l'épaisseur radiale du col peut être inférieure à la différence entre l'épaisseur radiale du col au niveau de la fenêtre et l'épaisseur radiale du décrochement. Ces variations d'épaisseur peuvent modifier le pourtour intérieur du col, sans pour autant modifier le pourtour extérieur du col, qui peut notamment rester circulaire..Outside the area where the window is formed, the radial thickness of the neck may be less than the difference between the radial thickness of the neck at the window and the radial thickness of the recess. These variations in thickness can modify the inner periphery of the neck, without modifying the outer circumference of the neck, which can in particular remain circular.

Le col peut être dressé sur un chant de la paroi latérale de la coque externe de telle sorte que l'épaisseur radiale de cette paroi latérale est de l'ordre de la somme de l'épaisseur radiale du col et de l'épaisseur radiale de la jupe de l'organe de fermeture. Ainsi, lorsque l'organe de fermeture est monté sur le récipient, la jupe latérale de l'organe de fermeture peut être inscrite selon la même génératrice que celle du pourtour latéral extérieur de la coque externe.The neck can be erected on a edge of the lateral wall of the outer shell so that the radial thickness of this side wall is of the order of the sum of the radial thickness of the neck and the radial thickness of the the skirt of the closure member. Thus, when the closure member is mounted on the container, the lateral skirt of the closure member may be inscribed according to the same generator as that of the outer lateral periphery of the outer shell.

Selon un mode particulier de réalisation de l'invention, le décrochement dépasse radialement du pourtour extérieur du récipient de 0,4 mm, le col a une épaisseur radiale de 1 mm au niveau de la fenêtre, et a une épaisseur radiale de 0,6 mm en dehors de la zone où est formée la fenêtre, et enfin la jupe de l'organe de fermeture a une épaisseur radiale de 1 mm.According to a particular embodiment of the invention, the recess protrudes radially from the outer periphery of the container by 0.4 mm, the neck has a radial thickness of 1 mm at the level of the window, and has a radial thickness of 0.6. mm outside the area where the window is formed, and finally the skirt of the closure member has a radial thickness of 1 mm.

L'organe de fermeture peut comporter une lèvre d'étanchéité appuyée contre le pourtour intérieur du récipient lorsqu'il est monté sur le récipient. Avantageusement, le récipient est configuré de telle sorte que le décrochement soit réalisé à un premier niveau axial, distinct d'un second niveau axial auquel sont réalisés les moyens de fixation destinés à coopérer avec l'organe de fermeture, ce deuxième niveau axial étant lui-même distinct d'un troisième niveau axial contre lequel ladite lèvre d'étanchéité vient s'appliquer. Ainsi la lèvre d'étanchéité est prévue pour venir au contact du troisième niveau axial qui est de préférence d'épaisseur radiale constante sur toute la circonférence du récipient. L'étanchéité peut ainsi être garantie.The closure member may comprise a sealing lip pressed against the inner periphery of the container when it is mounted on the container. Advantageously, the container is configured in such a way that the recess is made at a first axial level, distinct from a second axial level at which the fastening means intended to cooperate with the closure member are made, this second axial level being -same distinct from a third axial level against which said sealing lip is applied. Thus the sealing lip is provided to come into contact with the third axial level which is preferably of constant radial thickness over the entire circumference of the container. The seal can thus be guaranteed.

Le cas échéant, lorsque l'organe de fermeture est monté à demeure sur le récipient , il est avantageusement prévu des moyens coopératifs entre la coque externe et cet organe de fermeture de manière à les immobiliser respectivement en rotation l'un par rapport à l'autre.If necessary, when the closure member is permanently mounted on the container, it is advantageously provided with cooperative means between the outer shell and this closure member so as to immobilize them respectively in rotation with respect to the other.

L'organe de fermeture peut être en contact serrant sur le col lorsqu'il est monté sur le récipient. Il peut être retenu par vissage ou claquage sur le pourtour extérieur du récipient.The closure member may be in tight contact on the neck when mounted on the container. It can be retained by screwing or snapping on the outer periphery of the container.

Selon un mode de réalisation particulier de l'invention, l'organe de fermeture peut être équipé d'un moyen de distribution du produit contenu dans le récipient. En particulier, ce moyen de distribution peut être une pompe sans reprise d'air. Dans ce cas, le récipient peut être réalisé avec des parois latérales rigides et être équipé d'un piston ou bien encore être réalisé avec des parois déformables se collapsant les unes sur les autres au fur et à mesure de la vidange du récipient.According to a particular embodiment of the invention, the closure member may be equipped with a means of dispensing the product contained in the container. In particular, this dispensing means can be a pump without air intake. In this case, the container can be made with rigid side walls and be equipped with a piston or be made with deformable walls collapsing on each other as the emptying of the container.

La figure 1 montre un dispositif de conditionnement 1 selon l'invention. Figure 2, le dispositif de conditionnement comporte un récipient 2 dans lequel est contenu un produit P, le récipient 2 étant disposé dans une coque externe 3 et fermé par un organe de fermeture 4 du dispositif 1.The figure 1 shows a conditioning device 1 according to the invention. Figure 2 , the packaging device comprises a container 2 in which a product P is contained, the container 2 being disposed in an outer shell 3 and closed by a closure member 4 of the device 1.

Figure 2, le récipient 2 comporte une ouverture 5 concentrique à l'ouverture 6 de la coque externe via laquelle le récipient 2 est disposé dans cette coque externe. L'ouverture 5 est obturée par l'organe de fermeture 4 qui est retenu sur le récipient 2. Le récipient 2 est monté dans la coque externe 3 par translation le long d'un axe longitudinal X perpendiculaire à l'ouverture 6. La coque externe étant sensiblement cylindrique, cet axe longitudinal X est parallèle à une génératrice d'une paroi latérale 7 de la coque externe. Figure 2 , the container 2 has an opening 5 concentric with the opening 6 of the outer shell via which the container 2 is disposed in this outer shell. The opening 5 is closed by the closing member 4 which is retained on the container 2. The container 2 is mounted in the outer shell 3 by translation along a longitudinal axis X perpendicular to the opening 6. The shell outer being substantially cylindrical, this longitudinal axis X is parallel to a generator of a side wall 7 of the outer shell.

Sur la figure 1, la coque externe 3 est transparente et permet à l'utilisateur de voir le récipient 2 au moins au travers de la paroi latérale 7. L'organe de fermeture 4 est selon le mode de réalisation représenté sur les figures 1 et 2 sous la forme d'un bouchon. Le bouchon est ici opaque. Il est monté sur le récipient 2 de telle sorte qu'une jupe latérale 8 de l'organe de fermeture 4 est disposée dans la continuité de la paroi latérale 7. La paroi latérale 7 est définie selon une génératrice qui peut être superposable à une génératrice de la jupe latérale 8.On the figure 1 , the outer shell 3 is transparent and allows the user to see the container 2 at least through the side wall 7. The closure member 4 is according to the embodiment shown on the Figures 1 and 2 in the form of a plug. The cap is opaque here. It is mounted on the container 2 so that a lateral skirt 8 of the closure member 4 is disposed in the continuity of the side wall 7. The side wall 7 is defined according to a generator which can be superimposed on a generator of the side skirt 8.

De préférence, la paroi latérale 7 est cylindrique de section circulaire, la jupe latérale 8 de l'organe de fermeture 4 est alors également cylindrique de section circulaire. Dans ce mode de réalisation, le récipient 2 comporte un fond 9 orienté sensiblement parallèlement à l'ouverture 5, une paroi latérale 10 de ce récipient 2 étant dressée perpendiculairement au fond 9. La paroi latérale 10 comporte, à proximité de son chant libre 11, délimitant l'ouverture 5, des moyens de fixation 12 aptes à coopérer avec des moyens complémentaires 13 de la paroi latérale 7 de la coque externe de manière à ce que le récipient 2 puisse être immobilisé axialement dans cette coque externe 3.Preferably, the side wall 7 is cylindrical with a circular section, the lateral skirt 8 of the closure member 4 is then also cylindrical with a circular section. In this embodiment, the container 2 comprises a bottom 9 oriented substantially parallel to the opening 5, a side wall 10 of the container 2 being erected perpendicular to the bottom 9. The side wall 10 has, near its free edge 11 , delimiting the opening 5, fixing means 12 adapted to cooperate with complementary means 13 of the side wall 7 of the outer shell so that the container 2 can be axially immobilized in the outer shell 3.

La paroi latérale 10 du récipient 2 comporte une portion cylindrique 14, à l'opposé du chant libre 11, dressée sur le fond 9. La portion cylindrique 14 est de préférence de section transversale circulaire, cette portion cylindrique 14 étant entourée par la paroi latérale 7 de la coque externe 3 en position assemblée, tout en maintenant un jeu 15 entre les deux éléments. Le jeu 15 facilite l'assemblage du récipient 2 dans la coque externe 3 et permet un effet optique et esthétique avantageux. Un orifice 16 est prévu dans la coque externe 3 pour permettre le maintien à pression atmosphérique du volume délimité entre la coque externe et le récipient, que ce soit lors de l'assemblage du récipient 2 dans cette coque externe, et ou au fur et à mesure de la distribution du produit contenu dans le récipient, le cas échéant.The side wall 10 of the container 2 comprises a cylindrical portion 14, opposite the free edge 11, raised on the bottom 9. The cylindrical portion 14 is preferably of circular cross section, this cylindrical portion 14 being surrounded by the side wall 7 of the outer shell 3 in the assembled position, while maintaining a game 15 between the two elements. The clearance 15 facilitates the assembly of the container 2 in the outer shell 3 and allows an advantageous optical and aesthetic effect. An orifice 16 is provided in the outer shell 3 to allow maintenance at atmospheric pressure of the volume defined between the outer shell and the container, whether during assembly of the container 2 in the outer shell, and or as and when measuring the distribution of the product contained in the container, if any.

Les moyens de fixations 12 en coopération avec les moyens complémentaires 13 sont représentés selon une vue en coupe partielle, Figure 3. Les moyens de fixation 12 se présentent sous la forme d'un décrochement dépassant radialement vers l'extérieur de la paroi latérale 10. Ce décrochement comporte une première face 17 se dressant radialement perpendiculairement au pourtour extérieur de la paroi latérale 10 du récipient 2. Cette première face 17 se termine au niveau d'un retour 18 sensiblement parallèle à la paroi 10. Une deuxième face 19 relie le retour 18 à la paroi latérale 10, cette deuxième face 19 formant un angle différent de 90° avec la paroi 10. Selon un plan de coupe longitudinal, selon ledit axe X, le décrochement 12 a une forme de harpon.The fastening means 12 in cooperation with the complementary means 13 are represented in a partial sectional view, Figure 3 . The fastening means 12 are in the form of a recess protruding radially outwardly from the side wall 10. This recess comprises a first face 17 standing radially perpendicular to the outer periphery of the side wall 10 of the container 2. first face 17 terminates at a return 18 substantially parallel to the wall 10. A second face 19 connects the return 18 to the side wall 10, this second face 19 forming an angle different from 90 ° with the wall 10. According to FIG. a longitudinal sectional plane, along said axis X, the recess 12 has a harpoon shape.

La face 17 bien plane et non rayonnée, en variante non représentée, peut avantageusement être légèrement pentue vers le bas en s'étendant radialement vers l'extérieur du récipient 2, avec une pente d'environ 20° pour absorber le jeu axial entre la coque externe 3 et récipient 2.The flat and non-radiated face 17, in a variant that is not shown, can advantageously be slightly sloping downwards and extending radially outwardly of the container 2, with a slope of approximately 20 ° to absorb the axial clearance between the outer shell 3 and container 2.

Le décrochement 12 est ici annulaire et continu sur toute la circonférence de la paroi latérale 10. Lorsque le récipient 2 est monté dans la coque externe 3, le décrochement 12 vient coopérer avec le relief complémentaire 13, la coque externe 3 étant déformée lorsque le décrochement 12 est amené en engagement avec le relief complémentaire 13.The recess 12 is here annular and continuous over the entire circumference of the side wall 10. When the container 2 is mounted in the outer shell 3, the recess 12 cooperates with the complementary relief 13, the outer shell 3 being deformed when the recess 12 is brought into engagement with the complementary relief 13.

Le relief complémentaire 13 est ici sous la forme d'une fenêtre formée dans la paroi latérale 7. La fenêtre 13 est traversante, elle débouche au niveau du pourtour intérieur 20 de la paroi latérale 7, et au niveau du pourtour extérieur 21 de cette paroi latérale 7. Une bordure 22 de cette fenêtre comporte au moins une face 23 perpendiculaire à la paroi latérale 7, cette face perpendiculaire 23 étant celle contre laquelle la première face 17 vient en butée.The complementary relief 13 is here in the form of a window formed in the side wall 7. The window 13 is through, it opens at the inner periphery 20 of the side wall 7, and at the outer periphery 21 of this wall 7. A border 22 of this window has at least one face 23 perpendicular to the side wall 7, the perpendicular face 23 being the one against which the first face 17 abuts.

Pour former le récipient 2 avec un décrochement tel que 12 et la coque externe 3 avec une fenêtre traversante telle que 13, on réalise de préférence chacune de ces pièces par injection dans un moule à tiroirs ou coquilles, pour obtenir une précision importante des pièces fabriquées, avec des faces bien planes et des angles vifs. En effet, un moule à tiroirs ou coquilles, permet d'éviter la déformation de la pièce moulée du fait du retrait du moule.To form the container 2 with a recess such as 12 and the outer shell 3 with a through window such as 13, each of these parts is preferably made by injection into a mold with drawers or shells, to obtain a significant accuracy of the manufactured parts. , with flat faces and sharp angles. Indeed, a mold with drawers or shells, avoids deformation of the molded part due to removal of the mold.

La coque externe 3 est de préférence obtenue par moulage d'un matériau thermoplastique transparent tel qu'un copolymère statistique de styrène et d'acrylonitrile. Le récipient 2 est de préférence obtenu de moulage d'un matériau thermoplastique opaque de couleur blanche nacrée. II est par exemple réalisé en polypropylène.The outer shell 3 is preferably obtained by molding a transparent thermoplastic material such as a random copolymer of styrene and acrylonitrile. The container 2 is preferably obtained by molding an opaque thermoplastic material of white pearlescent color. It is for example made of polypropylene.

Dès lors que le décrochement 12 est engagé dans la fenêtre 13, un mouvement axial du récipient 2 relativement à la coque externe visant à les séparer est rendu impossible à obtenir manuellement, dans des conditions normales d'utilisation. Pour limiter également le jeu axial en enfoncement du récipient 2 dans la coque externe 3, un deuxième décrochement 24 est prévu sur le pourtour extérieur de la paroi latérale 10 du récipient configurée à distance du décrochement 12 de telle sorte qu'une face inférieure 25 de ce second décrochement 24 soit en appui sur le chant libre 26 de la paroi latérale 7, s'étendant entre le pourtour intérieur 20 et le pourtour extérieur 21.As the recess 12 is engaged in the window 13, an axial movement of the container 2 relative to the outer shell to separate them is made impossible to obtain manually under normal conditions of use. To also limit the axial clearance by driving the container 2 into the outer shell 3, a second recess 24 is provided on the outer periphery of the side wall 10 of the container configured at a distance from the recess 12 so that a lower face 25 of this second recess 24 is supported on the free edge 26 of the side wall 7, extending between the inner periphery 20 and the outer periphery 21.

Pour limiter le jeu radial du récipient 2 dans la coque externe 3, la paroi latérale 10 présente une surépaisseur 27 dans la zone définie entre les deux décrochements respectivement 12 et 24. Ainsi le jeu 15 d'aisance au montage n'affecte pas ensuite l'immobilisation du récipient 2 dans la coque externe 3, ce qui donne un aspect qualitatif à cet assemblage, et l'utilisateur a ainsi l'impression de n'avoir q'une seule pièce en main.To limit the radial clearance of the container 2 in the outer shell 3, the side wall 10 has an extra thickness 27 in the area defined between the two recesses 12 and 24 respectively. Thus, the clearance clearance during assembly does not affect the clearance. immobilization of the container 2 in the outer shell 3, which gives a qualitative aspect to this assembly, and the user thus has the impression of having only one piece in hand.

Pour que la limitation de ce jeu radial soit efficace, et pour renforcer l'immobilisation axiale du récipient 2 relativement à la coque externe 3, la coque externe comporte une deuxième fenêtre diamétralement opposée à la fenêtre 13, cette deuxième fenêtre étant symétrique à la première fenêtre relativement à un axe de symétrie de la coque externe. Cet axe de symétrie correspond à l'axe longitudinal X.So that the limitation of this radial clearance is effective, and to enhance the axial immobilization of the container 2 relative to the outer shell 3, the outer shell has a second window diametrically opposite the window 13, the second window being symmetrical to the first window relative to an axis of symmetry of the outer shell. This axis of symmetry corresponds to the longitudinal axis X.

Selon un mode de réalisation particulier de la coque externe 3, la paroi latérale 7 est cylindrique de section circulaire et comporte sur respectivement deux quarts de son pourtour, les deux quarts étant diamétralement opposés, huit fenêtres telles que 13. Chaque quart de pourtour présente quatre fenêtres telles que 13 dont deux à ouverture plus large que les deux autres, les ouvertures larges encadrant les deux autres.According to a particular embodiment of the outer shell 3, the side wall 7 is cylindrical with a circular cross section and comprises on two quarters of its circumference respectively, the two quarters being diametrically opposite, eight windows such as 13. Each quarter circumference has four windows such 13 of which two with wider opening than the other two, the wide openings framing the other two.

L'intérêt de la division en plusieurs fenêtres tels que 13 au sein d'une même portion du pourtour du col 28 permet de rendre plus solides les ponts de matière formant les bordures respectives de chacune de ces fenêtres.The advantage of dividing into several windows such as 13 within the same portion of the perimeter of the neck 28 makes it possible to make the bridges of material forming the respective edges of each of these windows more solid.

Les fenêtres telles que 13 sont de préférence formées au niveau d'un col 28 de la paroi latérale 7 délimitant ledit chant 26. Le col 28, en dehors des zones où sont formées les fenêtres 13, est configuré de tel sorte qu'il existe un faible jeu entre le décrochement 12 et ce pourtour intérieur du col. Ce faible jeu autorise ainsi la déformation du col 28 lors du passage en force du décrochement 12 sous la face inférieure 23 de la bordure 22 de la fenêtre 13, et ce pour chacune des fenêtres telles que 13.Windows such as 13 are preferably formed at a neck 28 of the side wall 7 defining said edge 26. The neck 28, outside the areas where the windows 13 are formed, is configured so that it exists. a weak clearance between the recess 12 and the inner periphery of the neck. This low clearance thus allows deformation of the neck 28 during the passage of force of the recess 12 under the lower face 23 of the edge 22 of the window 13, and for each of the windows such as 13.

Pour faciliter cette déformation, le col 28 est de préférence aminci dans les zones où il ne comporte pas de fenêtres 13. De ce fait, la zone du pourtour extérieur 21 au niveau du col 28 reste circulaire.To facilitate this deformation, the neck 28 is preferably thinned in the areas where it does not have windows 13. As a result, the zone of the outer periphery 21 at the neck 28 remains circular.

L'épaisseur radiale 29 du col 28 au niveau d'une fenêtre 13 est de l'ordre de 1 mm. L'épaisseur radiale 30 du décrochement 12 est de l'ordre de 0,4 mm. L'épaisseur radiale 31 du col 28 en dehors des fenêtres telles que 13 est sensiblement inférieure à la différence entre l'épaisseur 29 et l'épaisseur 30. Elle est dans cet exemple de l'ordre de 0,6 mm.The radial thickness 29 of the neck 28 at a window 13 is of the order of 1 mm. The radial thickness of the recess 12 is of the order of 0.4 mm. The radial thickness 31 of the neck 28 outside the windows such as 13 is substantially less than the difference between the thickness 29 and the thickness 30. It is in this example of the order of 0.6 mm.

Grâce à la conception selon l'invention, l'épaisseur radiale 50 définie entre le pourtour extérieur du récipient 2 et le pourtour extérieur du col 28 peut être minimisée.With the design according to the invention, the radial thickness 50 defined between the outer periphery of the container 2 and the outer periphery of the neck 28 can be minimized.

La section transversale du pourtour extérieur du col 28 est inférieure à la section transversale du pourtour extérieur d'une portion 32 de la paroi latérale 7 sur laquelle se dresse le col 28. L'organe de fermeture 4 est conçu de telle sorte que sa jupe latérale 8 entoure le col 28 et présente un pourtour extérieur défini selon une même génératrice que celle du pourtour extérieur de la portion 32. Par exemple, la jupe latérale 8 a une épaisseur radiale 33 de l'ordre de 1 mm. La portion 32 de la paroi latérale 7 a alors une épaisseur radiale 34 de l'ordre de la somme des épaisseurs radiales 29 et 33. Cette épaisseur radiale 34 est de l'ordre de 3 mm.The cross section of the outer periphery of the neck 28 is smaller than the cross section of the outer periphery of a portion 32 of the side wall 7 on which the neck 28 stands. The closure member 4 is designed so that its skirt 8 surrounds the neck 28 and has an outer periphery defined according to the same generator as that of the outer periphery of the portion 32. By for example, the side skirt 8 has a radial thickness 33 of the order of 1 mm. The portion 32 of the side wall 7 then has a radial thickness 34 of the order of the sum of the radial thicknesses 29 and 33. This radial thickness 34 is of the order of 3 mm.

L'organe de fermeture 4 obture le récipient 2 en étant retenu sur ce dernier via des moyens de fixation 35 présentés par la jupe latérale 8. Ces moyens de fixation 35 sont présentés sur le pourtour intérieur de la jupe 8 pour coopérer avec des moyens complémentaires 36 présentés dans une portion annulaire supérieure 37 du récipient 2. La portion annulaire supérieure 37 est disposée entre le second décrochement 24 et le chant libre 11 délimitant l'ouverture 5. La coopération entre les moyens de fixation 35 et 36 se fait dans une zone à l'aplomb de la paroi latérale 7, de sorte que la fixation de l'organe de fermeture 4 sur le récipient 2 maintient la faible épaisseur radiale obtenue entre le ledit récipient 2 et la coque externe 3.The closure member 4 closes the container 2 by being retained on the latter via fastening means 35 presented by the side skirt 8. These fastening means 35 are presented on the inner periphery of the skirt 8 to cooperate with complementary means 36 in the upper annular portion 37 of the container 2. The upper annular portion 37 is disposed between the second recess 24 and the free edge 11 defining the opening 5. The cooperation between the fixing means 35 and 36 is in a zone in line with the side wall 7, so that the fixing of the closure member 4 on the container 2 maintains the small radial thickness obtained between said container 2 and the outer shell 3.

Dans l'exemple représenté Figure 2, l'organe de fermeture 4 sous la forme d'un bouchon comporte une lèvre d'étanchéité 38 élastiquement déformée, en position assemblée, contre le pourtour intérieur du récipient 2 pour éviter toute fuite de produit pendant le stockage. La lèvre d'étanchéité 38 se dresse de manière concentrique relativement à la jupe latérale 8. Le bouchon est par exemple retenu par vissage, les moyens de fixation 35 et 36 étant alors des filets complémentaires.In the example shown Figure 2 , the closure member 4 in the form of a plug has a sealing lip 38 elastically deformed, in the assembled position against the inner periphery of the container 2 to prevent product leakage during storage. The sealing lip 38 is raised concentrically relative to the side skirt 8. The cap is for example retained by screwing, the fastening means 35 and 36 then being complementary threads.

En position assemblée, la jupe latérale 8 est de préférence montée de manière légèrement serrante de telle sorte que son pourtour intérieur vient en contact serrant avec le pourtour extérieur du col 28.In the assembled position, the lateral skirt 8 is preferably mounted in a slightly tightening manner so that its inner periphery comes into tight contact with the outer periphery of the neck 28.

Selon la variante de réalisation représentée Figure 5, l'organe de fermeture 4 est monté à demeure sur le récipient 2. Il est en particulier monté de manière définitive sur le récipient 2. Les moyens de fixations respectivement 35 et 36 sont par exemple prévus pour coopérer par encliquetage de telle sorte qu'il ne soit pas possible manuellement, dans des conditions normales d'usage, de détacher l'organe de fermeture 4 du récipient 2.According to the embodiment variant shown Figure 5 , the closing member 4 is permanently mounted on the container 2. It is in particular permanently mounted on the container 2. The attachment means 35 and 36 are, for example, provided for snap-in cooperation so that it is not possible manually, under normal conditions of use, to detach the closure member 4 from the receptacle 2.

Selon ce mode de réalisation, pour éviter toute rotation de l'organe de fermeture relativement à la coque externe, l'organe de fermeture 4 et la coque externe 3 présentent des stries verticales respectivement 60 et 61 en engagement mutuel.According to this embodiment, to prevent rotation of the closure member relative to the outer shell, the closure member 4 and the outer shell 3 have vertical ridges respectively 60 and 61 in mutual engagement.

Dans cette variante, pour permettre la distribution du produit P contenu dans le récipient 2, l'organe de fermeture 4 est équipé d'un moyen de distribution 39. Ce moyen de distribution est surmonté d'un organe d'actionnement 40. Dans l'exemple représenté, le moyen de distribution 39 est une pompe sans reprise d'air, et l'organe d'actionnement 40 un bouton poussoir. A chaque actionnement du bouton poussoir, une dose de produit est distribuée via la pompe, et un piston 41 prévu à l'intérieur du récipient 2 remonte. L'actionnement du bouton poussoir se fait par enfoncement selon l'axe longitudinal X du récipient 2. Pour optimiser la vidange du récipient 2, une bague de purge 42 est montée autour du corps de la pompe 39, cette bague de purge 42 étant configurée pour coopérer avec le piston 41 de manière à limiter le volume résiduel en fin de course du piston 41. La bague de purge est retenue à l'intérieur de la lèvre d'étanchéité 38.In this variant, to allow the dispensing of the product P contained in the container 2, the closure member 4 is equipped with a dispensing means 39. This dispensing means is surmounted by an actuating member 40. In the example shown, the dispensing means 39 is a pump without air intake, and the actuating member 40 is a push button. Each actuation of the push button, a dose of product is distributed via the pump, and a piston 41 provided inside the container 2 rises. The actuation of the push button is done by depressing along the longitudinal axis X of the container 2. To optimize the emptying of the container 2, a purge ring 42 is mounted around the body of the pump 39, this purge ring 42 being configured to cooperate with the piston 41 so as to limit the residual volume at the end of stroke of the piston 41. The purge ring is retained inside the sealing lip 38.

En variante, le récipient 2 peut être prévu avec des parois souples de telle sorte qu'au fur et à mesure de la distribution du produit, les parois du récipient 2 se collapsent les unes sur les autres.Alternatively, the container 2 may be provided with flexible walls so that as the product is dispensed, the walls of the container 2 collapse on each other.

En variante encore, une pompe simple avec reprise d'air peut être montée sur le récipient 2. Dans ce cas, contrairement à ce qui est représenté Figure 5, le fond 9 du récipient 2 ne comporte pas d'orifice traversant 43. En effet, l'orifice traversant 43 est utile dans les cas où un piston tel que 41 est prévu dans le récipient 2, pour permettre la remontée du piston sans créer de dépression dans le récipient 2.In another variant, a simple pump with air intake can be mounted on the container 2. In this case, contrary to what is shown Figure 5 , the bottom 9 of the container 2 does not have a through hole 43. Indeed, the through hole 43 is useful in cases where a piston such as 41 is provided in the container 2, to allow the piston to rise without creating depression in the container 2.

Dans toute la description, l'expression « comportant un » doit être considérée comme étant synonyme de « comportant au moins un », sauf si le contraire est spécifié.Throughout the description, the phrase "having one" should be considered synonymous with "having at least one", unless the opposite is specified.
