La poche est entièrement étanche vis-à-vis du produit cosmétique. Par exemple, elle est perméable aux gaz dégagés par le produit cosmétique. En variante, elle est étanche vis-à-vis du gaz dégagé par le produit cosmétique. Elle ne présente typiquement qu'un seul orifice, à travers lequel le corps plongeant est engagé. The cosmetic product is a fluid product, for example a liquid, a cream, an oil, a lotion or an emulsion. It is intended for make-up, or skin care or hair care or any other type of care. The flexible envelope is typically a plastic bag. The pouch is completely waterproof vis-à-vis the cosmetic product. For example, it is permeable to the gases released by the cosmetic product. As a variant, it is impervious to the gas evolved by the cosmetic product. It typically has only one orifice, through which the plunging body is engaged.
La poche est réalisée en tous matériaux adaptés. Par exemple, la poche est une poche de polyéthylène. La poche est monocouche. En variante, la poche est en un matériau multicouche, et comporte par exemple une couche de polyéthylène.  The pocket is made of all suitable materials. For example, the pocket is a polyethylene bag. The pocket is monolayer. In a variant, the pouch is made of a multilayer material, and comprises, for example, a layer of polyethylene.
Le corps plongeant présente toute sorte de section. Par exemple, il est à section circulaire. En variante, il est à section ovale, rectangulaire etc.  The diving body has all kinds of sections. For example, it is circular in section. Alternatively, it is oval section, rectangular etc.
Le corps plongeant est partiellement engagé à l'intérieur de l'enveloppe souple. Il présente donc un tronçon engagé à l'intérieur de l'enveloppe souple, et un tronçon situé à l'extérieur de l'enveloppe souple. Le bord de l'ouverture traversée par le corps plongeant est lié au corps plongeant par tous moyens adaptés pour réaliser une liaison étanche au produit cosmétique et au gaz éventuellement dégagé par le produit cosmétique. Par exemple, il est soudé sur le corps plongeant. En variante, il est collé sur le corps plongeant. Par exemple, le corps plongeant comporte à la jonction entre les tronçons interne et externe une collerette externe sur laquelle est fixée l'enveloppe souple.  The plunging body is partially engaged within the flexible envelope. It therefore has a section engaged inside the flexible envelope, and a section located outside the flexible envelope. The edge of the opening through which the plunging body is connected to the plunger body by any suitable means to achieve a tight connection to the cosmetic product and the gas possibly released by the cosmetic product. For example, it is welded to the diving body. Alternatively, it is glued on the plunging body. For example, the plunging body comprises at the junction between the inner and outer sections an outer flange on which is fixed the flexible envelope.
Le clapet est typiquement une pièce d'une matière plastique injectée. L'obturateur est normalement situé à l'extérieur de la chambre et l'organe élastique à l'intérieur de la chambre.  The valve is typically a piece of an injected plastic material. The shutter is normally located outside the chamber and the elastic member inside the chamber.
Cette disposition est particulièrement avantageuse quand le produit cosmétique dégage du gaz. La pression de gaz à l'intérieure de l'enveloppe souple sollicite le clapet vers sa position d'obturation. Le gaz ne peut donc pas s'échapper par l'orifice.  This arrangement is particularly advantageous when the cosmetic product releases gas. The gas pressure inside the flexible envelope urges the valve towards its closed position. The gas can not escape through the orifice.
Selon une caractéristique avantageuse de l'invention, la chambre est obturée vers l'intérieure de l'enveloppe souple par une paroi dans laquelle est ménagée l'orifice de prélèvement, la paroi présentant sur une face tournée vers l'intérieur de l'enveloppe souple une portée contre laquelle l'obturateur est en appui étanche en position d'obturation du clapet, et sur une face tournée vers la chambre une zone d'appui coopérant avec l'organe élastique pour rappeler le clapet en position d'obturation.  According to an advantageous characteristic of the invention, the chamber is closed towards the inside of the flexible envelope by a wall in which is formed the sampling orifice, the wall having on a face turned towards the inside of the envelope flexible a bearing against which the shutter is in sealing engagement in the closed position of the valve, and on a side facing the chamber a bearing zone cooperating with the elastic member to return the valve in the closed position.
La portée a toute forme adaptée. Par exemple, elle a une forme tronconique de section se réduisant vers l'orifice de prélèvement. L'obturateur dans ce cas, présente également une portion tronconique, destinée à coopérer avec ladite portée. Dans un autre exemple de réalisation, la portée a une forme annulaire. Avantageusement, l'orifice de prélèvement est une fente de forme allongée suivant une première direction, la partie d'extrémité du clapet étant conformée pour pouvoir être introduite à travers la fente. The scope has any suitable form. For example, it has a frustoconical section shape reducing to the sampling port. The shutter in this case, also has a frustoconical portion, intended to cooperate with said scope. In another embodiment, the scope has an annular shape. Advantageously, the sampling orifice is an elongate slot in a first direction, the end portion of the valve being shaped to be introduced through the slot.
Ceci permet de monter facilement le clapet.  This makes it easy to mount the valve.
Avantageusement, l'organe élastique comporte deux bras, la zone d'appui comportant deux surfaces d'appui disposées de part et d'autre de la fente et alignées suivant une seconde direction sensiblement perpendiculaire à la première direction.  Advantageously, the elastic member comprises two arms, the bearing zone comprising two bearing surfaces disposed on either side of the slot and aligned in a second direction substantially perpendicular to the first direction.
Une telle disposition est commode. L'organe élastique ne gêne pas l'écoulement du produit cosmétique à travers l'orifice de prélèvement.  Such an arrangement is convenient. The elastic member does not interfere with the flow of the cosmetic product through the sampling port.
En variante, l'orifice de prélèvement pourrait ne pas avoir une section en forme de fente, mais une section circulaire, rectangulaire, ovale, en croix à trois branches, quatre branches ou toute autre section. L'organe élastique, en variante, pourrait comporter plus de deux bras, par exemple trois bras, ou plus de trois bras. L'organe élastique peut être également conformé en forme de coupelle, avec un appui continu tout autour du passage. Dans ce cas, il comporte une ou plusieurs fenêtres découpées dans la coupelle pour permettre le passage du produit cosmétique.  Alternatively, the sampling port may not have a slit-shaped section, but a circular, rectangular, oval, cross-section with three branches, four branches, or any other section. The elastic member, as a variant, could comprise more than two arms, for example three arms, or more than three arms. The elastic member may also be shaped cup-shaped, with a continuous support all around the passage. In this case, it comprises one or more windows cut in the cup to allow the passage of the cosmetic product.
Avantageusement, l'âme est allongée suivant une direction axiale, les deux bras étant susceptible d'être introduit initialement à travers deux extrémités latérales de la fente puis déplacés circonférentiellement autour de la direction axiale jusqu'aux surfaces d'appui.  Advantageously, the core is elongate in an axial direction, the two arms being capable of being initially introduced through two lateral ends of the slot and then displaced circumferentially around the axial direction to the bearing surfaces.
En d'autres termes, le montage du clapet anti-retour dans le corps tubulaire se fait en introduisant ce clapet à travers l'orifice de prélèvement, puis en effectuant sensiblement un quart de tour de manière à placer les bras perpendiculairement à la première direction. Un tel montage est particulièrement commode et convient très bien à un clapet constitué d'une seule pièce. Les extrémités latérales de la fente correspondent aux deux extrémités de la fente opposées l'une à l'autre suivant la première direction.  In other words, the mounting of the non-return valve in the tubular body is done by introducing the valve through the sampling port, then making substantially a quarter turn so as to place the arms perpendicular to the first direction . Such an assembly is particularly convenient and is very suitable for a valve made of a single piece. The lateral ends of the slot correspond to the two ends of the slot opposite to each other in the first direction.
Avantageusement, chaque surface d'appui est jouxtée par des zones en saillie par rapport à ladite surface d'appui et disposée circonférentiellement entre ladite surface d'appui et les extrémités latérales de la fente.  Advantageously, each bearing surface is adjoined by areas projecting from said bearing surface and disposed circumferentially between said bearing surface and the lateral ends of the slot.
Les zones en saillie limitent le débattement circonférentiel des bras, et maintiennent ceux-ci contre les surfaces d'appui. Ils empêchent en particulier que les bras élastiques retombent dans la fente.  The protruding areas limit the circumferential movement of the arms, and maintain them against the bearing surfaces. They prevent in particular that the elastic arms fall back into the slot.
Pour le montage du clapet, les bras élastiques doivent franchir les zones en saillie lors du mouvement circonférentiel les amenant de la première direction à la deuxième direction. La hauteur des zones en saillie, et l'élasticité des bras, sont calculées pour que le déplacement circonférentiel des bras depuis les extrémités latérales de la fente jusqu'aux surfaces d'appui soit possible sous l'effet d'une forte sollicitation appliquée par un utilisateur, mais qu'un déplacement en sens inverse ne soit pas possible en l'absence d'une sollicitation appliquée par un utilisateur. For the mounting of the valve, the elastic arms must cross the protruding areas during the circumferential movement bringing them from the first direction to the second direction. The height of the protruding areas, and the elasticity of the arms, are calculated so that the circumferential movement of the arms from the lateral ends of the slot up to the bearing surfaces is possible under the effect of a strong stress applied by a user, but that a displacement in the opposite direction is not possible in the absence of a request applied by a user.
Avantageusement, la partie d'extrémité du clapet comporte un organe d'appui prolongeant l'âme au-delà des deux bras.  Advantageously, the end portion of the valve comprises a support member extending the core beyond the two arms.
Ainsi, quand on engage un organe de prélèvement de produits cosmétiques dans le corps plongeant, il est facile d'agencer l'extrémité de l'organe de prélèvement pour que cette extrémité vienne appuyer sur l'organe d'appui et déplacer le clapet jusqu'à sa position de dégagement.  Thus, when a cosmetic product sampling member is engaged in the plunging body, it is easy to arrange the end of the sampling member so that this end comes to bear on the support member and to move the flap until 'to its release position.
L'organe d'appui peut avoir toute sorte de forme, fonction de l'organe de prélèvement prévu pour être engagé dans la chambre.  The support member may have any kind of shape, depending on the sampling member intended to be engaged in the chamber.
Avantageusement, le dispositif comprend un bouchon amovible obturant une extrémité de la chambre située hors de l'enveloppe souple.  Advantageously, the device comprises a removable plug closing one end of the chamber located outside the flexible envelope.
Ce bouchon permet donc de fermer l'extrémité de la chambre qui est opposée au clapet. Ainsi, au cas où une petite quantité de produit cosmétique et/ou de gaz se trouve dans la chambre, le gaz et/ou le produit cosmétique restent confinés à l'intérieur de la chambre. Le bouchon est retiré quand un utilisateur veut prélever du produit cosmétique.  This plug thus makes it possible to close the end of the chamber which is opposite to the valve. Thus, in the case where a small amount of cosmetic product and / or gas is in the chamber, the gas and / or the cosmetic product remain confined within the chamber. The cap is removed when a user wants to take cosmetic product.
Le bouchon est monté sur la chambre par tout type de liaison adapté, par exemple par une liaison vissée, ou une liaison à baïonnette etc.  The plug is mounted on the chamber by any type of suitable connection, for example by a screw connection, or a bayonet connection etc.
Typiquement, la liaison est étanche au gaz dégagé par le produit cosmétique. Typically, the connection is gas-tight by the cosmetic product.
Avantageusement, le dispositif comprend un suremballage rigide autour de l'enveloppe souple, le corps plongeant traversant le suremballage et étant fixé au suremballage. Advantageously, the device comprises a rigid overpack around the flexible envelope, the plunger passing through the overpack and being attached to the overpack.
Le suremballage est par exemple en carton, ou en tout autre matériau adapté. Il permet d'éviter que le produit cosmétique se répande, en cas de fuite de l'enveloppe souple. Il permet de conférer une apparence soignée à l'ensemble de conditionnement et de distribution. Notamment, de conférer une forme stable audit ensemble. L'enveloppe souple, au contraire, a une forme qui varie au fur et à mesure que le produit cosmétique est prélevé.  The overpack is for example cardboard, or any other suitable material. It prevents the cosmetic product from spreading, in case of leakage of the flexible envelope. It allows to confer a neat appearance to the set of packaging and distribution. In particular, to confer a stable form on the whole. The flexible envelope, on the contrary, has a shape that varies as the cosmetic product is removed.
Le corps plongeant est fixé au suremballage par tout moyen. Par exemple, il comporte deux collerettes externes définissant entres elles une gorge dans laquelle est engagée un bord de l'ouverture traversée par le corps plongeant. Par exemple, l'enveloppe souple est fixée à l'une des deux collerettes.  The plunging body is attached to the overpack by any means. For example, it comprises two outer flanges defining between them a groove in which is engaged an edge of the opening through which the plunging body. For example, the flexible envelope is attached to one of the two flanges.
Selon un second aspect, l'invention concerne un ensemble de conditionnement et de distribution d'un produit cosmétique, l'ensemble comprenant un dispositif de conditionnement ayant les caractéristiques ci-dessus, et un organe de prélèvement de produit cosmétique adapté pour être engagé dans le corps plongeant. According to a second aspect, the invention relates to a package for packaging and dispensing a cosmetic product, the assembly comprising a device for conditioning having the above characteristics, and a cosmetic product sampling member adapted to be engaged in the plunging body.
Avantageusement, l'organe de prélèvement est une seringue. Un tel mode de prélèvement est commode et permet à l'utilisateur de ne pas être en contact avec le produit cosmétique lors du prélèvement.  Advantageously, the sampling member is a syringe. Such a sampling method is convenient and allows the user not to be in contact with the cosmetic product during sampling.
Avantageusement, l'organe de prélèvement comprend un corps de seringue prévu pour être engagé dans le corps plongeant jusqu'à une position de prélèvement, un piston coulissant à l'intérieur du corps de seringue, un organe d'étanchéité externe interposé entre le corps plongeant et le corps de seringue, et un organe d'étanchéité interne interposé entre le piston et le corps de seringue.  Advantageously, the sampling member comprises a syringe body adapted to be engaged in the plunging body to a sampling position, a piston sliding inside the syringe body, an external sealing member interposed between the body plunging and the syringe body, and an internal sealing member interposed between the piston and the syringe body.
Ainsi, le prélèvement du produit cosmétique est effectué de manière très simple, en déplaçant le piston à l'intérieur du corps de seringue.  Thus, the removal of the cosmetic product is performed very simply, by moving the piston inside the syringe body.
L'organe d'étanchéité externe est par exemple une lèvre portée par le corps de seringue ou par le corps plongeant. L'organe d'étanchéité interne est par exemple un embout en un matériau élastique, fixé à une extrémité du piston. Les deux organes d'étanchéité sont typiquement en un caoutchouc naturel ou synthétique.  The external sealing member is for example a lip carried by the syringe body or the plunging body. The internal sealing member is for example a tip made of an elastic material, attached to one end of the piston. The two sealing members are typically made of a natural or synthetic rubber.
Avantageusement, le corps de seringue en position de prélèvement maintient le clapet en position de dégagement à rencontre de la force de rappel de l'organe élastique.  Advantageously, the syringe body in the sampling position maintains the valve in the disengaged position against the restoring force of the elastic member.
Il est ainsi possible de prélever le produit cosmétique.  It is thus possible to take the cosmetic product.
Par exemple, une extrémité du corps de seringue vient appuyer sur l'organe d'appui du clapet et déplace celui-ci vers la paroi de la chambre.  For example, one end of the syringe body presses against the support member of the valve and moves it to the wall of the chamber.
Avantageusement, l'ensemble comprend une fixation amovible du corps de seringue au corps plongeant.  Advantageously, the assembly comprises a removable attachment of the syringe body to the plunging body.
Le prélèvement de produits cosmétiques peut ainsi être fait très commodément. La fixation permet de maintenir le corps de seringue en position de prélèvement, et donc de maintenir le clapet dans sa position de dégagement de l'orifice de prélèvement.  The removal of cosmetics can be done very conveniently. The attachment makes it possible to keep the syringe body in the sampling position, and thus to keep the valve in its position of disengagement from the sampling orifice.
La fixation est de tout type adapté. Par exemple, la fixation est de type à baïonnette, ou de type vissé, ou de tout autre type adapté.  The attachment is of any suitable type. For example, the fastener is of the bayonet type, or of the screw type, or of any other suitable type.
Selon un troisième aspect, l'invention vise un procédé d'assemblage d'un dispositif de conditionnement pour un produit cosmétique ayant les caractéristiques ci-dessus, le procédé comprenant :  According to a third aspect, the invention relates to a method of assembling a packaging device for a cosmetic product having the above characteristics, the method comprising:
- une étape d'engagement du clapet à travers l'orifice de prélèvement suivant une direction axiale ;  - A step of engagement of the valve through the sampling port in an axial direction;
- une étape de verrouillage du clapet dans l'orifice de prélèvement, par rotation du clapet par rapport au corps plongeant autour de la direction axiale.  - A step of locking the valve in the sampling port, by rotating the valve relative to the body dipping around the axial direction.
Ainsi, le montage du clapet sur le corps plongeant est particulièrement simple. D'autres caractéristiques et avantages de l'invention ressortiront de la description détaillée qui en est donnée ci-dessous à titre indicatif et nullement limitatif, en référence aux figures annexées, parmi lesquelles : Thus, the mounting of the valve on the plunging body is particularly simple. Other features and advantages of the invention will emerge from the detailed description which is given below by way of indication and in no way limiting, with reference to the appended figures, among which:
- la figure 1 est une vue en coupe d'un ensemble de conditionnement et de distribution de produits cosmétiques conforme à l'invention, représenté dans une configuration où la seringue n'est pas engagée dans le corps plongeant ;  - Figure 1 is a sectional view of a set of packaging and dispensing of cosmetic products according to the invention, shown in a configuration where the syringe is not engaged in the plunging body;
- la figure 2 est une vue similaire à celle de la figure 1 , avec la seringue engagée dans le corps plongeant ; et  - Figure 2 is a view similar to that of Figure 1, with the syringe engaged in the plunging body; and
- la figure 3 est une vue de face de la paroi du corps plongeant portant l'orifice de prélèvement.  - Figure 3 is a front view of the wall of the plunger body carrying the sampling port.
L'ensemble 1 représenté sur les figures 1 et 2 est destiné au conditionnement et à la distribution d'un produit cosmétique. Ce produit cosmétique est par exemple un produit décolorant pour les fibres kératinique, tels que les cheveux ou les sourcils. Un tel produit contient un composé susceptible de s'oxyder en présence d'oxygène.  The assembly 1 shown in Figures 1 and 2 is for the packaging and dispensing of a cosmetic product. This cosmetic product is for example a bleaching product for keratin fibers, such as the hair or the eyebrows. Such a product contains a compound that can oxidize in the presence of oxygen.
L'ensemble 1 comporte un dispositif 3 de conditionnement pour le produit cosmétique, et un organe 5 destiné à prélever le produit cosmétique stocké dans le dispositif 3 en vue de son utilisation.  The assembly 1 comprises a device 3 for packaging the cosmetic product, and a member 5 for taking the cosmetic product stored in the device 3 for use.
Le dispositif de conditionnement 3 comprend :  The conditioning device 3 comprises:
- une enveloppe souple 7 étanche ;  a flexible envelope 7 sealed;
- de préférence, un suremballage rigide 9 autour de l'enveloppe souple 7 ;  - Preferably, a rigid overwrap 9 around the flexible envelope 7;
- un corps tubulaire plongeant 1 1 , traversant l'enveloppe souple 7 et lié de manière étanche à l'enveloppe souple 7, le corps plongeant 1 1 délimitant intérieurement une chambre 13 débouchant à l'intérieur de l'enveloppe souple 7 par un orifice de prélèvement 15 ;  - A tubular plunging body 1 1, passing through the flexible envelope 7 and sealingly attached to the flexible envelope 7, the plunging body 1 1 internally defining a chamber 13 opening into the flexible envelope 7 through an orifice sampling 15;
- un clapet 17 susceptible d'adopter une position d'obturation de l'orifice de prélèvement 15 et une position de dégagement de l'orifice de prélèvement 15 ;  a valve 17 capable of adopting a closed position of the sampling orifice 15 and a release position of the sampling orifice 15;
- un produit cosmétique, non représenté, disposé dans l'enveloppe souple 7.  a cosmetic product, not shown, disposed in the flexible envelope 7.
L'enveloppe souple 7 est une poche de polyéthylène, étanche au produit cosmétique et non étanche au gaz dégagé par le produit cosmétique. Par exemple, la poche est formée d'une feuille de polyéthylène. Par exemple, la poche est formée en pliant la feuille de polyéthylène et en soudant les deux demi-feuilles l'une à l'autre.  The flexible envelope 7 is a polyethylene bag, impervious to the cosmetic product and not gas-tight by the cosmetic product. For example, the pocket is formed of a polyethylene sheet. For example, the pouch is formed by folding the polyethylene sheet and welding the two half-sheets to each other.
L'enveloppe souple 7 présente une ouverture unique 19, qui est traversée par le corps plongeant 1 1 .  The flexible envelope 7 has a single opening 19, which is traversed by the plunger 11.
Le suremballage 9 est une boîte en carton, de forme sensiblement parallélépipédique. Le corps plongeant 1 1 traverse le suremballage. Plus précisément, le suremballage 9 présente une ouverture 21 , positionnée en vis-à-vis de l'ouverture 19 de l'enveloppe 7, à travers laquelle le corps plongeant 1 1 est engagé. The overwrap 9 is a cardboard box, substantially parallelepiped shape. The plunging body 11 passes through the overpack. More specifically, the overpack 9 has an opening 21, positioned vis-à-vis the opening 19 of the casing 7, through which the plunger 1 1 is engaged.
Le corps plongeant 1 1 est typiquement une pièce injectée en matière plastique. Il présente un tronçon 23 engagé dans la poche de polyéthylène et un tronçon 25 situé hors de la poche de polyéthylène et hors du suremballage 9. Le corps plongeant 1 1 présente un axe central X. Dans l'exemple représenté, sa section droite, perpendiculairement à l'axe X, est circulaire.  The plunging body 1 1 is typically an injected piece of plastic material. It has a section 23 engaged in the polyethylene bag and a section 25 located outside the polyethylene bag and out of the overpack 9. The dipping body 1 1 has a central axis X. In the example shown, its cross section, perpendicularly at the X axis, is circular.
Le corps plongeant 1 1 comporte une paroi latérale tubulaire 24 et une paroi d'extrémité 25 dans laquelle est ménagé l'orifice de prélèvement 15. La paroi d'extrémité 25 obture la chambre vers l'intérieur de l'enveloppe souple 7. Elle est solidaire d'une extrémité axiale de la paroi tubulaire 24. Le corps plongeant 1 1 , à l'extrémité axiale opposée à la paroi 25, est ouvert.  The plunging body 11 comprises a tubular side wall 24 and an end wall 25 in which the sampling orifice 15 is formed. The end wall 25 closes the chamber towards the inside of the flexible envelope 7. It is integral with an axial end of the tubular wall 24. The dipping body 1 1 at the axial end opposite the wall 25 is open.
Le corps plongeant 1 1 comporte encore une collerette externe 27 s'étendant radialement à partir d'une surface externe de la paroi 24 tubulaire. La collerette 27 s'étend sur toute la périphérie du corps plongeant 1 1 . L'enveloppe souple 7 est soudée étanche sur la collerette 27.  The dipping body 11 also has an outer collar 27 extending radially from an outer surface of the tubular wall 24. The flange 27 extends over the entire periphery of the plunger 11. The flexible envelope 7 is sealed on the flange 27.
Le corps plongeant 1 1 comporte encore une seconde collerette externe 29, s'étendant radialement à partir d'une surface externe de la paroi tubulaire 24. Les collerettes 27 et 29 délimitent entre elles une gorge 31 . Le bord périphérique 33 délimitant l'ouverture 21 du suremballage est engagé dans la gorge 31 , liant ainsi le corps tubulaire 1 1 au suremballage 9.  The plunging body 11 further comprises a second outer flange 29, extending radially from an outer surface of the tubular wall 24. The flanges 27 and 29 delimit a groove 31 between them. The peripheral edge 33 delimiting the opening 21 of the overwrap is engaged in the groove 31, thus binding the tubular body 1 1 to the overwrap 9.
La paroi d'extrémité 25 comporte une zone périphérique annulaire 35 solidaire de la paroi tubulaire 24, prolongée par un col cylindrique 37. Le col cylindrique 37 est coaxial à l'axe X. Il fait saillie par rapport à la zone annulaire 35 vers l'extérieur de la chambre 13. II est partiellement fermé par une cloison 39, sensiblement perpendiculaire à l'axe X, dans laquelle est découpé l'orifice de prélèvement 15.  The end wall 25 has an annular peripheral zone 35 integral with the tubular wall 24, extended by a cylindrical neck 37. The cylindrical neck 37 is coaxial with the axis X. It projects relative to the annular zone 35 towards the outside of the chamber 13. It is partially closed by a partition 39, substantially perpendicular to the axis X, in which the sampling orifice 15 is cut out.
La cloison 39 est décalée axialement à l'intérieur du col 37, de telle sorte que le bord libre 41 du col 37 fait saillie par rapport à la cloison 39, à l'opposé de la chambre 13.  The partition 39 is axially offset inside the neck 37, so that the free edge 41 of the neck 37 protrudes with respect to the partition 39, opposite the chamber 13.
Le bord libre 41 , vers l'intérieur du col 37, définit une portée d'étanchéité sensiblement tronconique 43.  The free edge 41, towards the inside of the neck 37, defines a substantially frustoconical sealing surface 43.
Le clapet 4 comporte :  The valve 4 comprises:
- un obturateur 53, prévu pour obturer l'orifice de prélèvement 15 en position d'obturation ;  a shutter 53, designed to close the sampling orifice 15 in the closed position;
- une âme 55 liée à l'obturateur et engagée dans l'orifice de prélèvement 15 ;  a core 55 connected to the shutter and engaged in the sampling orifice 15;
- une partie d'extrémité 57 liée à l'âme 55, pourvue d'un organe élastique 59 rappelant le clapet en position d'obturation. Dans l'exemple représenté, l'obturateur 53 est un disque ayant une tranche 61 biseautée. La tranche 61 présente une forme tronconique, complémentaire de celle de la portée 43. Elle coopère avec cette portée 43 pour obturer le passage 19 en position d'obturation. L'obturateur 53 présente encore une grande face supérieure 63, à l'opposé de la cloison 39. Cette grande face, en position d'obturation, est de niveau avec le bord libre 41 . - An end portion 57 connected to the core 55, provided with an elastic member 59 reminding the valve in the closed position. In the example shown, the shutter 53 is a disc having a slice 61 beveled. The wafer 61 has a frustoconical shape, complementary to that of the span 43. It cooperates with this seat 43 to close the passage 19 in the closed position. The shutter 53 also has a large upper face 63, opposite the partition 39. This large face, in the closed position, is flush with the free edge 41.
L'âme 55 s'étend selon l'axe X. Elle est par exemple à section circulaire, ou à section en croix, ou peut présenter toutes sortes d'autres formes.  The core 55 extends along the axis X. It is for example circular section, or section cross, or can present all kinds of other forms.
L'obturateur 53 est solidaire d'une première extrémité axiale de l'âme, la partie d'extrémité 57 étant solidaire d'une seconde extrémité axiale de l'âme 55, opposée à la première.  The shutter 53 is integral with a first axial end of the core, the end portion 57 being integral with a second axial end of the core 55, opposite to the first.
L'organe élastique 59 comporte deux bras 65, diamétralement opposés par rapport à l'axe X. Les deux bras 65 s'inscrivent sensiblement dans un même plan contenant l'axe X. Chaque bras 65 présente la forme d'une griffe. Plus précisément, chaque bras 65, dans l'exemple de réalisation représenté sur la figure 1 , comporte un premier tronçon s'étendant radialement vers l'extérieur à partir de l'âme 55, prolongé par un second tronçon s'étendant à partir du premier tronçon, radialement vers l'extérieur et axialement vers l'obturateur 53.  The elastic member 59 comprises two arms 65, diametrically opposite to the axis X. The two arms 65 are substantially in the same plane containing the X axis. Each arm 65 has the shape of a claw. More specifically, each arm 65, in the exemplary embodiment shown in FIG. 1, comprises a first section extending radially outwardly from the core 55, extended by a second section extending from the first section, radially outwards and axially towards the shutter 53.
La partie d'extrémité 57 comporte encore un organe d'appui 71 , prolongeant l'âme 55 axialement au-delà des bras 65. L'organe d'appui 71 s'inscrit sensiblement dans le même plan que les deux bras 65.  The end portion 57 further comprises a support member 71, extending the core 55 axially beyond the arms 65. The support member 71 is substantially in the same plane as the two arms 65.
L'orifice de prélèvement 15, comme visible sur la figure 3, est une fente présentant une section, perpendiculairement à l'axe X, allongée suivant une première direction. Cette première direction D1 est matérialisée par un trait mixte sur la figure 3. La portée 43 entoure l'orifice de prélèvement  The sampling orifice 15, as visible in FIG. 3, is a slot having a section, perpendicular to the axis X, elongate in a first direction. This first direction D1 is shown by a dashed line in FIG. 3. The span 43 surrounds the sampling orifice
La paroi 25 présente une zone d'appui 73 coopérant avec l'organe élastique 59 pour rappeler le clapet dans sa position d'obturation. Comme visible sur la figure 3, la zone d'appui comporte deux surfaces d'appui 75 disposées de part et d'autre de la fente, et alignées suivant une seconde direction D2 sensiblement perpendiculaire à la première direction D1 . Quand le clapet est monté sur le corps, les extrémités libres des bras 65 sont en appui sur les surfaces d'appui 75. Les surfaces d'appui 75 sont ménagées sur une surface 76 de la cloison 39 tournée vers la chambre 13.  The wall 25 has a bearing zone 73 cooperating with the elastic member 59 to return the valve to its closed position. As can be seen in FIG. 3, the bearing zone comprises two bearing surfaces 75 disposed on either side of the slot, and aligned in a second direction D2 substantially perpendicular to the first direction D1. When the valve is mounted on the body, the free ends of the arms 65 are supported on the bearing surfaces 75. The bearing surfaces 75 are formed on a surface 76 of the partition 39 facing the chamber 13.
Les surfaces d'appui 75 sont disposées de telle sorte que les deux bras 65 du clapet sont susceptibles d'être introduit axialement à travers les deux extrémités latérales opposées de la fente, puis déplacés circonférentiellement autour de la direction axiale X jusqu'aux surfaces d'appui 75. Les extrémités latérales de la fente sont opposées l'une à l'autre selon la première direction D1 . The bearing surfaces 75 are arranged such that the two arms 65 of the valve are capable of being introduced axially through the two opposite lateral ends of the slot and then displaced circumferentially around the axial direction X to the bearing surfaces 75. The lateral ends of the slot are opposed to each other in the first direction D1.
En d'autres termes, les deux bras 65 sont susceptibles d'être introduits à travers la fente axialement, les deux bras étant alors orientés de manière à être placés dans un plan contenant l'axe X et la première direction D1 . Ils sont ensuite pivotés de manière à être placés dans un plan contenant l'axe X et la seconde direction D2.  In other words, the two arms 65 are capable of being introduced through the slot axially, the two arms then being oriented so as to be placed in a plane containing the axis X and the first direction D1. They are then rotated so as to be placed in a plane containing the X axis and the second direction D2.
De manière à maintenir les extrémités libres des bras sur les surfaces d'appui et empêcher qu'elles retombent dans la fente 15, chaque surface d'appui 75 est jouxtée par deux zones en saillie 77, disposée de part et d'autre de la surface 75, circonférentiellement autour de l'axe X entre ladite surface d'appui 75 et les extrémités latérales de la fente. Les zones en saillie font saillies par rapport aux surfaces d'appui. Elles sont délimitées par des bords biseautés 79, de manière à faciliter le franchissement des zones en saillie 77 par les bras 65.  In order to keep the free ends of the arms on the bearing surfaces and prevent them from falling into the slot 15, each bearing surface 75 is adjoined by two projecting zones 77, disposed on either side of the surface 75, circumferentially about the X axis between said bearing surface 75 and the lateral ends of the slot. The protruding areas protrude from the bearing surfaces. They are delimited by bevelled edges 79, so as to facilitate the crossing of the protruding zones 77 by the arms 65.
Le dispositif 3 comporte encore un bouchon amovible 81 (figure 1 ), obturant l'extrémité de la chambre 13 située hors de l'enveloppe souple. Le bouchon 81 comporte un fond 83 et une jupe 85 solidaire et entourant le fond 83. La jupe 85 comporte un filetage interne 87 coopérant avec un filetage externe 89 ménagé à l'extrémité du tronçon 23 du corps plongeant.  The device 3 further comprises a removable plug 81 (Figure 1), closing the end of the chamber 13 located outside the flexible envelope. The plug 81 has a bottom 83 and a skirt 85 integral and surrounding the bottom 83. The skirt 85 has an internal thread 87 cooperating with an external thread 89 formed at the end of the section 23 of the plunging body.
L'organe de prélèvement 5 (figure 2) est une seringue. La seringue 5 comporte un corps de seringue tubulaire 91 et un piston 93. Le corps tubulaire 91 comporte une paroi périphérique tubulaire 95 délimitant un volume interne 97 dans lequel se déplace le piston 93. La paroi périphérique 95 est partiellement fermée à une extrémité par une paroi ajourée 99. Elle est ouverte à l'opposée de la paroi ajourée 99. Le corps tubulaire 91 comporte encore une jupe cylindrique 101 , entourant l'extrémité de la paroi périphérique 95 opposée à la paroi ajourée 99. La paroi 95 et la jupe 101 sont raccordées l'une à l'autre par un pont de matière annulaire 103.  The sampling member 5 (Figure 2) is a syringe. The syringe 5 comprises a tubular syringe body 91 and a piston 93. The tubular body 91 has a tubular peripheral wall 95 delimiting an internal volume 97 in which the piston 93 moves. The peripheral wall 95 is partially closed at one end by a perforated wall 99. It is open to the opposite of the perforated wall 99. The tubular body 91 further comprises a cylindrical skirt 101, surrounding the end of the peripheral wall 95 opposite the perforated wall 99. The wall 95 and the skirt 101 are connected to each other by a bridge of annular material 103.
La paroi périphérique 95 présente un diamètre externe légèrement inférieur au diamètre interne de la paroi tubulaire 24 du corps plongeant.  The peripheral wall 95 has an outer diameter slightly smaller than the internal diameter of the tubular wall 24 of the plunging body.
La paroi ajourée 99 comporte une pluralité de lumière 105, découpée autour d'une zone centrale pleine 107. La zone centrale 107 porte une nervure cylindrique 109, se dressant vers l'extérieur du volume 97 interne.  The perforated wall 99 has a plurality of lumens 105, cut around a solid central zone 107. The central zone 107 carries a cylindrical rib 109, rising towards the outside of the internal volume 97.
Le piston 93 comporte une tête 1 1 1 engagée dans le volume 97, une partie de préhension 1 13 et une tige 1 15 raccordant la tête 1 1 1 à la partie de préhension 1 13. La tête 1 1 1 porte un organe d'étanchéité 1 17. Une chambre de prélèvement de volume variable est délimitée entre la tête 1 1 1 et la paroi ajourée 99. Le volume de la chambre varie en fonction du déplacement du piston le long du corps de seringue. La tête est constamment en appui étanche contre la paroi périphérique 95, par l'intermédiaire de l'organe d'étanchéité 1 17. The piston 93 comprises a head 1 1 1 engaged in the volume 97, a gripping portion 1 13 and a rod 1 15 connecting the head 1 1 1 to the gripping portion 1 13. The head 1 1 1 carries a body of 1 Sealing 1 17. A sampling chamber of variable volume is delimited between the head 1 1 1 and the perforated wall 99. The volume of the chamber varies as a function of the displacement of the piston along the syringe body. The head is constantly sealing against the peripheral wall 95, via the sealing member 1 17.
Le corps de piston 91 porte un autre organe d'étanchéité 1 19, formé d'une lèvre située sensiblement le long de la ligne de jonction entre la paroi périphérique 95 et la paroi ajourée 99. La lèvre 1 19 fait saillie vers l'extérieur par rapport à la paroi périphérique 95, et entoure celle-ci sur toute sa périphérie.  The piston body 91 carries another sealing member 1 19, formed of a lip located substantially along the line of junction between the peripheral wall 95 and the perforated wall 99. The lip 1 19 projects outwardly relative to the peripheral wall 95, and surrounds it over its entire periphery.
L'ensemble comporte encore une fixation amovible du corps de seringue au corps plongeant, non représentée. Cette fixation est par exemple de type baïonnette. Elle lie une face interne de la jupe 101 à une face externe du tronçon 23 du corps plongeant.  The assembly further comprises a removable attachment of the syringe body to the plunging body, not shown. This attachment is for example bayonet type. It links an inner face of the skirt 101 to an outer face of the section 23 of the plunging body.
La fabrication de l'ensemble ci-dessus va maintenant être détaillée.  The manufacture of the above set will now be detailed.
Le produit cosmétique est d'abord placé dans l'enveloppe 7, puis cette enveloppe 7 est fermée de telle sorte qu'il ne subsiste plus que l'ouverture 19.  The cosmetic product is first placed in the envelope 7, then this envelope 7 is closed so that only the opening 19 remains.
Le corps plongeant 1 1 est fabriqué, par injection d'une matière plastique. Le clapet 17 est lui aussi fabriqué par injection d'une matière plastique.  The plunging body 1 1 is manufactured by injection of a plastic material. The valve 17 is also manufactured by injection of a plastic material.
Le clapet 17 est ensuite monté sur le corps plongeant 1 1 . 11 est d'abord placé dans une orientation où les bras 65 sont situés dans un plan contenant l'axe X et la première direction D1 . Il est ensuite déplacé axialement jusqu'à ce que la tranche 61 vienne en appui contre la portée 43. L'organe d'appui 71 et les bras 65 font alors saillis sous la cloison 39. Un opérateur saisit ensuite le clapet par l'intermédiaire de la partie d'appui 71 et lui fait effectuer un quart de tour de manière à placer les bras 65 selon la seconde direction D2. Au cours de ce mouvement de rotation autour de l'axe X, les bras 65 doivent franchir les zones en saillie 77 avant d'atteindre les surfaces d'appui 75. Le franchissement des zones en saillie est aidé du fait que ces zones présentent des bords biseautés 79. Une fois les bras 65 en appui contre les surfaces d'appui 75, ces bras 65 sollicitent l'obturateur 53 contre la portée d'étanchéité 43.  The valve 17 is then mounted on the plunger 1 1. 11 is first placed in an orientation where the arms 65 are located in a plane containing the X axis and the first direction D1. It is then moved axially until the slice 61 bears against the bearing surface 43. The support member 71 and the arms 65 then protrude under the partition 39. An operator then grasps the valve via of the bearing portion 71 and makes it a quarter turn so as to place the arms 65 in the second direction D2. During this rotational movement about the X axis, the arms 65 must cross the projecting zones 77 before reaching the bearing surfaces 75. The crossing of the projecting zones is aided by the fact that these zones have Beveled edges 79. Once the arms 65 bear against the bearing surfaces 75, these arms 65 urge the shutter 53 against the sealing surface 43.
Le corps plongeant 1 1 est ensuite partiellement introduit à l'intérieur de l'enveloppe souple 7, et le bord périphérique de l'ouverture 19 est soudé sur la collerette 27. Puis, le bord 33 de l'ouverture 31 du suremballage 9 est engagé dans la gorge 31 . Enfin, le capuchon 81 est vissé à l'extrémité du corps plongeant 1 1 .  The plunging body 1 1 is then partially inserted inside the flexible envelope 7, and the peripheral edge of the opening 19 is welded to the flange 27. Then, the edge 33 of the opening 31 of the overpack 9 is engaged in the throat 31. Finally, the cap 81 is screwed to the end of the plunging body January 1.
Le corps de seringue 91 et la lèvre 1 19 sont injectés d'une pièce. Le piston 93 est lui aussi injecté d'une pièce. L'organe d'étanchéité 1 17 est ensuite monté sur la tête du piston et la tête du piston est engagée dans le volume 97 délimité par le corps de seringue.  The syringe body 91 and the lip 1 19 are injected in one piece. The piston 93 is also injected in one piece. The sealing member 1 17 is then mounted on the piston head and the piston head is engaged in the volume 97 defined by the syringe body.
Le fonctionnement de l'ensemble de conditionnement et de distribution va maintenant être détaillé. Tant qu'il n'est pas nécessaire de prélever du produit cosmétique hors de l'enveloppe 7, le bouchon 81 reste en place et ferme la chambre 13 délimitée par le corps plongeant 1 1 . Les bras 65 maintiennent le clapet dans sa position d'obturation de l'orifice de prélèvement. The operation of the packaging and distribution package will now be detailed. As long as it is not necessary to take cosmetic product out of the casing 7, the plug 81 remains in place and closes the chamber 13 delimited by the plunger 11. The arms 65 hold the valve in its closed position of the sampling port.
Quand un utilisateur veut prélever du produit cosmétique, il commence par dévisser le bouchon 81 et le sépare du corps plongeant 1 1 .  When a user wants to take cosmetic product, he begins by unscrewing the cap 81 and separates it from the plunging body 1 1.
Il engage ensuite la seringue 5 à l'intérieur du corps plongeant. Il engage la seringue de telle sorte que la paroi ajourée 99 soit tournée vers la paroi terminale 25 du corps plongeant. L'utilisateur enfonce le corps de seringue 91 à l'intérieur du corps plongeant, pratiquement sur toute sa longueur. Il continue ce mouvement jusqu'à ce que le bord libre du corps plongeant 1 1 vienne en butée contre le pont de matière 103 raccordant la jupe 101 au corps de seringue. Il fixe ensuite le corps de seringue au corps plongeant par l'intermédiaire des moyens de fixation prévus à cet effet, par exemple en effectuant une légère rotation du corps de seringue par rapport au corps plongeant dans le cas d'une fixation à baïonnette.  He then engages the syringe 5 inside the diving body. It engages the syringe so that the perforated wall 99 is turned towards the end wall 25 of the plunging body. The user pushes the syringe barrel 91 into the plunging body substantially along its entire length. It continues this movement until the free edge of the plunging body 1 1 comes into abutment against the material bridge 103 connecting the skirt 101 to the syringe body. It then attaches the syringe body to the plunger body via the fixing means provided for this purpose, for example by performing a slight rotation of the syringe body relative to the plunger in the case of a bayonet attachment.
Le corps de seringue est alors bloqué axialement par rapport au corps plongeant, parallèlement à l'axe X. Dans cette situation, la paroi périphérique 95 s'étend à proximité immédiate de la paroi tubulaire 24. La lèvre 1 19 assure l'étanchéité entre les deux parois.  The syringe body is then locked axially relative to the plunger body, parallel to the axis X. In this situation, the peripheral wall 95 extends in the immediate vicinity of the tubular wall 24. The lip 1 19 seals between both walls.
Comme illustré sur la figure 2, dans cette position, la zone pleine 107 de la paroi ajourée est en appui contre l'organe d'appui 71 . Le clapet est alors bloqué axialement à sa position de dégagement de l'orifice de prélèvement. Pour prélever du produit cosmétique, l'utilisateur saisi la partie de préhension 1 13 du piston et tire le piston selon l'axe X, de manière à écarter la tête 1 1 1 du piston de la paroi ajourée 99. Le produit cosmétique est alors aspiré à travers l'orifice de prélèvement 15, et à travers les lumières 105 jusque dans la chambre de prélèvement, c'est-à-dire entre la tête du piston et la paroi ajourée 99. L'utilisateur continu à déplacer le piston jusqu'à ce que quantité souhaitée de produit cosmétique soit prélevée.  As illustrated in FIG. 2, in this position, the solid zone 107 of the perforated wall bears against the support member 71. The valve is then locked axially at its release position of the sampling port. To collect cosmetic product, the user grasps the grip portion 1 13 of the piston and pulls the piston along the axis X, so as to move the head 1 January 1 of the piston of the perforated wall 99. The cosmetic product is then sucked through the sampling orifice 15, and through the lights 105 into the sampling chamber, that is to say between the piston head and the perforated wall 99. The user continues to move the piston up to the desired amount of cosmetic product is removed.
Il sépare ensuite la seringue 5 du corps plongeant 1 1 , et remet en place le bouchon 81 . Le clapet 17 revient dans sa position d'obturation de l'orifice de prélèvement sous l'effet de la force de rappel des bras 65.  It then separates the syringe 5 from the plunger 1 1, and puts back the stopper 81. The valve 17 returns to its closed position of the sampling port under the effect of the restoring force of the arms 65.
