Description

ORGANE DE BOUCHAGE ET DISTRIBUTEUR DE PRODUIT  CLOGGING MEMBER AND PRODUCT DISPENSER
FLUIDE COMPRENANT UN TEL ORGANE  FLUID COMPRISING SUCH AN ORGAN
La présente invention concerne un organe de bouchage destiné à être monté sur une ouverture d'un réservoir de produit fluide, de manière à constituer un distributeur de produit fluide. D'ailleurs, la présente demande concerne également un distributeur de produit fluide comprenant un tel organe de bouchage. Divers organes de bouchage sont utilisés sur des distributeurs de tous types dans de nombreux domaines, et notamment dans les domaines de la parfumerie, de la cosmétique ou encore de la pharmacie. La fonction première d'un organe de bouchage est de permettre une distribution sélective du produit fluide stocké dans le réservoir sur lequel l'organe de bouchage est monté. The present invention relates to a closure member intended to be mounted on an opening of a fluid reservoir, so as to constitute a fluid dispenser. Moreover, the present application also relates to a fluid dispenser comprising such a closure member. Various closures are used on dispensers of all types in many fields, including the fields of perfumery, cosmetics or pharmacy. The primary function of a closure member is to allow selective dispensing of the fluid product stored in the reservoir on which the closure member is mounted.
Dans l'art antérieur, on connaît déjà le document WO2007/125241 qui décrit un organe de bouchage comprenant un corps de base formant un orifice de distribution de produit fluide, une pièce de montage sur laquelle le corps de base est reçu fixement, et un couvercle d'obturation destiné à obturer l'orifice de distribution, le couvercle étant relié à la pièce de montage par une articulation, le couvercle et la pièce étant réalisés de manière monobloc, le couvercle étant initialement relié à la pièce de montage par au moins un pont de matière cassable avant de la première ouverture du couvercle.  In the prior art, WO2007 / 125241 is already known which describes a closure member comprising a base body forming a fluid dispensing orifice, a mounting piece on which the base body is fixedly received, and a shutter cover for closing the dispensing orifice, the cover being connected to the mounting piece by a hinge, the cover and the part being made in one piece, the cover being initially connected to the mounting piece by at least a bridge of breakable material before the first opening of the lid.
L'organe de bouchage de ce document fait partie des organes de bouchage que l'on peut qualifier d'« inertes », en ce qu'il n'incorpore pas de pompe ni de valve. En d'autres termes, le produit fluide n'est pas mis sous pression dans une chambre interne formée par l'organe de bouchage. L'organe de bouchage s'apparente plutôt à un dispositif de fermeture classique comprenant un orifice de distribution obturable à l'aide d'un bouchon. Ce type particulier d'organe de bouchage est destiné à être associé à un réservoir sous la forme d'une poche souple que l'utilisateur peut écraser. Les distributeurs incorporant ce type d'organe de bouchage sont souvent utilisés comme échantillon, et peuvent de ce fait être insérés dans des magazines spécialisés à titre de promotion. Or, il existe des réglementations quant à la résistance des distributeurs, car ils sont soumis à des pressions importants, notamment lorsque les magazines sont empilés. Il ne faut pas que la poche souple éclate, ni que l'organe de bouchage fuit. En général, c'est l'organe de bouchage qui supporte toute la pression, car son épaisseur, même faible, est supérieure à celle de la poche. The closure member of this document is part of closure devices that can be described as "inert", in that it does not incorporate a pump or valve. In other words, the fluid product is not pressurized in an internal chamber formed by the closure member. The closure member is rather similar to a conventional closure device comprising a dispensing orifice closable with a plug. This particular type of closure member is intended to be associated with a reservoir in the form of a flexible bag that the user can crush. Dispensers incorporating this type of closure device are often used as a sample, and can therefore be inserted in specialized magazines as a promotion. However, there are regulations regarding the resistance of distributors, because they are subject to significant pressure, especially when magazines are stacked. It is not necessary that the flexible pouch burst, or that the closure member leaks. In general, it is the closure member that supports all the pressure, because its thickness, even small, is greater than that of the pocket.
L'organe de bouchage du document WO2007/125241 n'a pas été spécialement conçu pour supporter la pression exercée par une pile de magazines.  The closure member of WO2007 / 125241 has not been specifically designed to withstand the pressure exerted by a stack of magazines.
La présente invention a pour but d'améliorer la résistance à la pression de ce type d'organe de bouchage, sans pour autant compliquer la fabrication, ni le montage.  The present invention aims to improve the pressure resistance of this type of closure member, without complicating the manufacture or assembly.
Pour atteindre ce but, la présente invention prévoit que le corps de base soit entièrement inscrit à l'intérieur de la pièce de montage. Avantageusement, le couvercle est aussi entièrement inscrit à l'intérieur de la pièce de montage, de sorte que l'épaisseur maximale de l'organe de bouchage est définit par la pièce de montage. Selon un mode de réalisation pratique, la pièce de montage comprend une couronne qui entoure le corps de base et le couvercle. Avantageusement, la couronne définit une épaisseur maximale de l'organe de bouchage. Avantageusement, l'organe de bouchage présente une configuration générale plate de manière à s'étendre dans un plan, l'épaisseur maximale de la couronne s'étend perpendiculairement au plan. La couronne remplit ainsi une fonction de support ou de poutre qui encaisse la totalité de la pression exercée sur le distributeur. Le corps de base et le couvercle ne sont pas contraints ou pressés contre la pièce de montage.  To achieve this object, the present invention provides that the base body is fully inscribed within the mounting piece. Advantageously, the lid is also fully inscribed inside the mounting piece, so that the maximum thickness of the closure member is defined by the mounting piece. According to a practical embodiment, the mounting piece comprises a ring which surrounds the base body and the cover. Advantageously, the ring defines a maximum thickness of the closure member. Advantageously, the closure member has a generally flat configuration so as to extend in a plane, the maximum thickness of the crown extends perpendicularly to the plane. The crown thus fulfills a support or beam function that takes up all the pressure exerted on the distributor. The base body and cover are not forced or pressed against the mounting piece.
Selon une autre caractéristique de l'invention, le corps de base est reçu par encliquetage étanche à l'intérieur de la couronne de la pièce de montage. Etant donné que le corps de base n'est pas soumis à la pression et que la couronne supporte aisément la pression, l'encliquetage étanche du corps dans la couronne ne subi pas de contraintes qui pourraient rompre l'étanchéité et créer des fuites. According to another characteristic of the invention, the base body is received by snap sealing inside the ring of the mounting piece. Since the base body is not subjected to pressure and the crown easily withstands the pressure, the snap-in body in the crown does not suffer any stress that could break the seal and create leaks.
Selon un autre aspect de l'invention, le couvercle définit une épaisseur maximale de l'organe de bouchage. Dans ce cas, la couronne et le couvercle définissent chacun une épaisseur maximale de l'organe de bouchage. La couronne et le couvercle supportent individuellement la pression, sans contraintes entre eux : la couronne constitue un support annulaire, alors que le couvercle constitue un support central localisé.  According to another aspect of the invention, the lid defines a maximum thickness of the closure member. In this case, the ring and the cover each define a maximum thickness of the closure member. The crown and the lid individually support the pressure, without constraints between them: the ring constitutes an annular support, while the lid constitutes a localized central support.
Avantageusement, la pièce de montage définit une zone de scellage destinée à venir en contact étanche avec l'ouverture du réservoir.  Advantageously, the mounting piece defines a sealing zone intended to come into sealed contact with the opening of the reservoir.
La présente invention définit également un distributeur de produit fluide dont le réservoir de volume variable comprend au moins une feuille souple définissant une ouverture dans laquelle l'organe de bouchage est monté. Le réservoir est de préférence formé par une poche constituée par une ou deux feuilles souples. En variante, le réservoir peut également être formé à partir d'une feuille souple et d'un autre élément, comme par exemple une coque thermoformée. Il n'est d'ailleurs pas exclu que l'organe de bouchage puisse être monté sur la coque thermoformée, qui formerait alors une ouverture pour la réception de l'organe de bouchage.  The present invention also defines a fluid dispenser whose variable volume reservoir comprises at least one flexible sheet defining an opening in which the closure member is mounted. The reservoir is preferably formed by a pocket consisting of one or two flexible sheets. Alternatively, the reservoir may also be formed from a flexible sheet and another element, such as a thermoformed shell. It is also not excluded that the closure member can be mounted on the thermoformed shell, which would then form an opening for the reception of the closure member.
Un tel distributeur peut présenter une épaisseur très réduite de l'ordre de 3 à 5 millimètres, voire moins. L'épaisseur du distributeur est essentiellement constituée par l'épaisseur de l'organe de bouchage, étant donné que les feuilles souples présentent une épaisseur non significative. On peut par conséquent utiliser un tel distributeur plat en tant qu'échantillon de produit fluide insérable dans les magazines de la presse : la résistance à la pression est garantit par la couronne, et optionnellement par le couvercle, qui définissent l'épaisseur maximale de l'organe de bouchage.  Such a dispenser may have a very small thickness of the order of 3 to 5 millimeters or less. The thickness of the distributor is essentially constituted by the thickness of the closure member, since the flexible sheets have a non-significant thickness. Therefore, such a flat distributor can be used as a fluid sample insertable in magazines of the press: the resistance to pressure is guaranteed by the crown, and optionally by the lid, which define the maximum thickness of the clogging organ.
La présente invention sera maintenant plus amplement décrite en référence aux dessins joints donnant à titre d'exemple non limitatif un mode de réalisation de l'invention.  The present invention will now be more fully described with reference to the accompanying drawings giving by way of non-limiting example an embodiment of the invention.
Sur les figures : - la figure 1 est une vue de dessus d'un organe de bouchage selon l'invention, In the figures: FIG. 1 is a view from above of a closure member according to the invention,
- la figure 2 est une vue en coupe transversale verticale à travers l'organe de bouchage de la figure 1 à l'état fermé, et  FIG. 2 is a vertical cross-sectional view through the closure member of FIG. 1 in the closed state, and
- la figure 3 est une vue similaire à celle de la figure 2 pour l'organe de bouchage à l'état ouvert.  - Figure 3 is a view similar to that of Figure 2 for the closure member in the open state.
Nous allons tout d'abord décrire en détail la structure et le fonctionnement d'un organe de bouchage fabriqué selon un mode de réalisation non limitatif de l'invention. L'intégration de cet organe de bouchage dans un distributeur selon la présente invention sera décrite dans un second temps.  We will first describe in detail the structure and operation of a closure member manufactured according to a non-limiting embodiment of the invention. The integration of this closure member in a dispenser according to the present invention will be described in a second step.
L'organe de bouchage représenté sur les figures 1 à 4 a été désigné dans son ensemble par la lettre C. Il comprend essentiellement trois éléments constitutifs, à savoir un corps de base 1 , une pièce de montage 20 et un couvercle 25. La pièce de montage 20 et le couvercle 25 peuvent être réalisés de manière monobloc de manière à ne former qu'une seule pièce de moulage. Le couvercle 25 peut être relié à la pièce de base 20 par une articulation 26 qui peut se présenter sous la forme d'un pont de matière souple. L'organe de bouchage est relativement plat de sorte que l'on peut définir un plan P dans lequel il s'étend.  The closure member shown in Figures 1 to 4 has been designated as a whole by the letter C. It comprises essentially three constituent elements, namely a base body 1, a mounting piece 20 and a lid 25. The piece 20 and the cover 25 can be made in one piece so as to form a single molding part. The lid 25 may be connected to the base piece 20 by a hinge 26 which may be in the form of a bridge of flexible material. The closure member is relatively flat so that one can define a plane P in which it extends.
Le corps de base 1 se présente ici sous la forme d'une rondelle ou d'un disque définissant une cuvette concave 15 qui est percée en son centre par un orifice de distribution 17 qui traverse l'épaisseur du corps pour déboucher au niveau de la surface inférieure. La cuvette 15 va servir de récipient de récupération de produit fluide. Sur sa périphérie externe, le corps de base forme une bride annulaire 12 qui fait saillie radialement vers l'extérieur.  The base body 1 is here in the form of a washer or disk defining a concave bowl 15 which is pierced at its center by a dispensing orifice 17 which passes through the thickness of the body to open at the level of the body. lower surface. The bowl 15 will serve as a container for recovering fluid product. On its outer periphery, the base body forms an annular flange 12 which protrudes radially outwardly.
Le corps de base 1 est de préférence réalisé par injection/moulage de matière plastique. Il présente ici une forme annulaire ou circulaire : toutefois, d'autres formes géométriques sont envisageables, comme par exemple des formes polygonales ou oblongues. La surface inférieure du corps de base est ici parfaitement plane : on peut toutefois imaginer que cette surface 13 soit réalisée avec des profils quelconques ou particuliers favorisant par exemple l'écoulement de produit fluide en direction de l'orifice de distribution 17. The base body 1 is preferably made by injection molding / plastic molding. Here it has an annular or circular shape: however, other geometric shapes are possible, such as polygonal or oblong shapes. The bottom surface of the base body is here perfectly flat: it can however be imagined that this surface 13 is realized with any particular or particular profiles favoring for example the flow of fluid product in the direction of the dispensing orifice 17.
La pièce de montage 20 se présente dans ce mode de réalisation non limitatif sous la forme d'un anneau qui est de préférence complet et fermé. On peut toutefois imaginer des pièces de montage de forme partiellement annulaire ou encore polygonale. Il faut de toute façon que cette pièce de montage soit adaptable sur le corps de base. La pièce de montage 20 comprend une couronne annulaire 21 qui présente une épaisseur verticale ou axiale E dans la direction perpendiculaire au plan P. Cette épaisseur E est l'épaisseur maximale de l'organe de bouchage. La couronne définit sur sa périphérie interne une gorge annulaire d'encliquetage 22 pour la réception fixe et étanche de la bride 12 du corps de base 1 . En variante non représentée, le corps de base et la pièce de montage peuvent être surmoulés ou bi-injectés. Sur sa périphérie externe, la couronne se prolonge en formant une zone de scellage 23 de forme sensiblement ou parfaitement annulaire. Cette zone de scellage 23 va servir de surface de fixation pour la feuille souple constitutive de la poche souple du distributeur de l'invention, comme on le verra ci-après.  The mounting piece 20 is in this non-limiting embodiment in the form of a ring which is preferably complete and closed. However, it is possible to imagine mounting pieces of partially annular or polygonal shape. In any case, this mounting piece must be adaptable to the basic body. The mounting piece 20 comprises an annular ring 21 which has a vertical or axial thickness E in the direction perpendicular to the plane P. This thickness E is the maximum thickness of the closure member. The ring defines on its inner periphery an annular locking groove 22 for the fixed and sealed reception of the flange 12 of the base body 1. Alternatively not shown, the base body and the mounting piece can be overmoulded or bi-injected. On its outer periphery, the ring is extended by forming a sealing zone 23 of substantially or perfectly annular shape. This sealing zone 23 will serve as a fixing surface for the flexible sheet constituting the flexible pouch of the dispenser of the invention, as will be seen below.
Le couvercle 25, qui est avantageusement réalisé de manière monobloc avec la pièce de montage 20, présente également une forme de disque ou de rondelle qui est disposé à l'intérieur de la pièce de montage 20, comme on peut le voir sur les figures. Le couvercle peut cependant présenter une découpe de préhension 29 au niveau duquel l'utilisateur peut saisit le couvercle. Le couvercle 25 est relié à la périphérie interne de la couronne 22 par une articulation souple 26, mais également par un ou plusieurs pont(s) de matière 28, comme on peut le voir sur la figure 1 . La surface supérieure du couvercle 25 peut être située dans le même plan que le haut de la couronne 21 . Ainsi, le bord périphérique extérieur du couvercle 25 est séparé de la couronne par des segments de fentes annulaires 29 séparés par les ponts de matière 28 et l'articulation souple 26. En son centre, le couvercle 25 définit un pointeau d'obturation 27 qui s'étend à partir de la surface inférieure du couvercle. Le couvercle est entièrement inscrit dans l'encombrement de la pièce de montage. Le pointeau peut également être excentré, si l'orifice de distribution 17 l'est aussi. The lid 25, which is advantageously made in one piece with the mounting piece 20, also has a disk or washer shape which is disposed inside the mounting piece 20, as can be seen in the figures. The lid may however have a gripping cutout 29 at which the user can grip the lid. The cover 25 is connected to the inner periphery of the ring 22 by a flexible articulation 26, but also by one or more bridge (s) of material 28, as can be seen in FIG. The upper surface of the cover 25 may be located in the same plane as the top of the ring 21. Thus, the outer peripheral edge of the cover 25 is separated from the ring by segments of annular slots 29 separated by the material bridges 28 and the flexible joint 26. In its center, the cover 25 defines a closure needle 27 which extends from the bottom surface of the lid. The lid is fully inscribed in the clutter of the mounting piece. The needle can also be eccentric if the dispensing orifice 17 is also eccentric.
On peut remarquer que l'épaisseur maximale du couvercle, au niveau du pointeau 27, est égale à celle de la couronne, à savoir E, qui correspond à l'épaisseur maximale de l'organe de bouchage.  It may be noted that the maximum thickness of the lid, at the needle 27, is equal to that of the crown, namely E, which corresponds to the maximum thickness of the closure member.
Lorsque l'organe de bouchage C vient d'être assemblé, comme représenté sur la figure 1 , le couvercle 25 est relié à la pièce de montage 20 non seulement par l'articulation souple 26, mais également par les ponts de matière 28 qui sont alors encore intacts. Telle est la configuration de l'organe de bouchage C avant première utilisation ou ouverture du couvercle. Dans cette configuration initiale, l'intégrité des ponts de matière 28 donne à l'utilisateur ou l'acheteur une indication visuelle infaillible comme quoi l'organe de bouchage n'a jamais été ouvert. En d'autres termes, les ponts de matière 28 remplissent une fonction de garantie de premier usage à l'utilisateur.  When the closure member C has just been assembled, as shown in FIG. 1, the cover 25 is connected to the mounting piece 20 not only by the flexible articulation 26, but also by the material bridges 28 which are then still intact. This is the configuration of the closure member C before first use or opening of the lid. In this initial configuration, the integrity of the material bridges 28 gives the user or purchaser an infallible visual indication that the closure member has never been opened. In other words, the material bridges 28 fulfill a function of guarantee of first use to the user.
On peut également remarquer que l'organe de bouchage C de la présente invention présente une épaisseur très réduite de l'ordre de 3 à 5 millimètres. Ceci est rendu possible du fait que le corps de base 1 et le couvercle 25 s'emboîtent entièrement à l'intérieur de la pièce de montage 20. L'épaisseur maximale de l'organe de bouchage correspond à l'épaisseur maximale E de la couronne 21 , ce qui lui confère une très bonne résistance à la pression. En effet, la conception monobloc et massive de la couronne lui permet d'assurer une fonction de support, d'étai ou d'entretoise qui est pratiquement indéformable, même lorsque soumise à des pressions considérables. Cette résistance extrême permet de réaliser des distributeurs susceptibles d'être insérés dans des magazines.  It may also be noted that the closure member C of the present invention has a very reduced thickness of the order of 3 to 5 millimeters. This is made possible by the fact that the base body 1 and the lid 25 fully fit inside the mounting piece 20. The maximum thickness of the closure member corresponds to the maximum thickness E of the 21, which gives it a very good resistance to pressure. Indeed, the one-piece and solid design of the crown allows it to provide a support function, strut or spacer that is virtually indeformable, even when subjected to considerable pressure. This extreme resistance makes it possible to produce distributors that can be inserted in magazines.
Sur la figure 4, on voit un distributeur comprenant un réservoir R constitué de deux feuilles souples F reliées ensemble sur leurs périphéries de manière à forme un poche souple destinée à contenir du produit fluide. Une des feuilles F est percée d'une ouverture annulaire plane O qui est soudée (ou autrement fixée) sur la zone de scellage 23 de l'organe de bouchage C. Avant la première utilisation de distributeur, le couvercle doit être ouvert, ce qui cause la rupture des ponts 28 et dégage l'orifice de distribution 17. En appuyant sur la poche souple, du produit fluide est refoulé à travers l'orifice de distribution et peut être récupéré par l'utilisateur au niveau de la coupelle 15. Ensuite le couvercle peut à nouveau être remis en place de manière à obturer l'orifice de distribution. In Figure 4, there is shown a dispenser comprising a reservoir R consisting of two flexible sheets F connected together on their peripheries so as to form a flexible bag for containing fluid. One of the sheets F is pierced with a flat annular opening O which is welded (or otherwise fixed) to the sealing zone 23 of the closure member C. Before the first use of the dispenser, the cover must being opened, which causes the bridges 28 to rupture and disengages the dispensing orifice 17. By pressing on the flexible bag, fluid product is discharged through the dispensing orifice and can be retrieved by the user at the level of the dispensing orifice. the cup 15. Then the cover can be put back in place so as to close the dispensing orifice.
Grâce aux caractéristiques de l'invention, on peut aisément fabriquer à moindre coût un distributeur de produit fluide dont l'organe de bouchage est mis en place avant formation de la poche. D'autre part, cet organe de bouchage peut avantageusement intégrer des moyens de sécurité de premier usage sans pour autant compliquer son moulage et son assemblage. Au final, on obtient un distributeur qui présente une épaisseur minimale et une résistance maximale. On peut de ce fait insérer un tel distributeur dans des magazines à titre d'échantillon publicitaire.  Thanks to the characteristics of the invention, it is easy to manufacture at low cost a fluid dispenser whose closure member is put in place before forming the bag. On the other hand, this closure member may advantageously integrate security means of first use without complicating its molding and assembly. In the end, we obtain a distributor that has a minimum thickness and maximum strength. One can thus insert such a distributor into magazines as an advertising sample.
