Description

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 ainsi qu'un procédé de fabrication d'un tel distributeur. 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 and a method of manufacturing such a dispenser. 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.

L'organe de bouchage de la présente invention 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 de la présente invention s'apparente plutôt à un dispositif de fermeture classique comprenant un orifice de distribution obturable à l'aide d'un bouchon.The closure member of the present invention is part of the closure members that can be described as "inert", in that it does not incorporate pump or valve. In other words, the fluid product is not pressurized in an internal chamber formed by the closure member. The closure member of the present invention is rather similar to a conventional closure device comprising a dispensing orifice closable with a plug.

Cependant, un problème inhérent aux dispositifs de fermeture « inertes » réside dans le fait qu'il est difficile d'assurer à l'utilisateur que l'organe de bouchage n'a jamais été ouvert pour distribuer du produit fluide. L'utilisateur qui achète un distributeur de produit fluide veut en effet être assuré que le distributeur n'a jamais été utilisé auparavant. Pour pallier ce problème, il existe déjà dans l'art antérieur de nombreux systèmes de garantie de premier usage qui sont associés à l'organe de bouchage. On peut par exemple envelopper l'organe de bouchage avec un film que le premier utilisateur déchire pour pouvoir accéder à l'organe de bouchage. Les organes de bouchage vissables peuvent incorporer une bande de garantie de premier usage qui empêche le dévissage du bouchon. A la première utilisation, l'utilisateur arrache la bande ou force l'ouverture du bouchon détruisant ainsi la bande.However, an inherent problem with "inert" closure devices is that it is difficult to assure the user that the closure member has never been opened to dispense fluid. The user who buys a fluid dispenser wants to be assured that the dispenser has never been used before. To overcome this problem, there are already in the prior art many first-use guarantee systems that are associated with the closure member. For example, it is possible to wrap the closure member with a film that the first user tears in order to be able to access the closure member. Screw-on closures may incorporate a first-use guarantee tape that prevents unscrewing of the cap. AT the first use, the user tears the tape or forces the opening of the cap thus destroying the tape.

L'organe de bouchage de la présente invention n'est pas du type dévissable, et une telle bande périphérique arrachable ou destructible n'est pas appropriée pour la présente invention.The closure member of the present invention is not of the unscrewable type, and such a peelable or destructible peripheral band is not suitable for the present invention.

Ainsi, la présente invention propose un organe de bouchage destiné à être monté sur une ouverture d'un réservoir de produit fluide, ledit organe comprenant un corps de base formant un orifice de distribution de produit fluide, une pièce de montage destinée à être montée fixement sur le corps de base, et un couvercle d'obturation destiné à obturer l'orifice de distribution, le couvercle étant relié à la pièce de montage par une articulation, caractérisé en ce que le couvercle et la pièce sont réalisés de manière monobloc, le couvercle étant initialement relié à la pièce de montage, avant première ouverture du couvercle, par au moins un pont de matière cassable lors de la première ouverture. Cette pièce de montage remplit une fonction de pièce intermédiaire ou de liaison entre le couvercle d'obturation et le corps de base. En effet, sans cette pièce de montage, il ne serait pas possible de réaliser des ponts de matière cassable qui maintiennent le couvercle d'obturation en position fermée avant première utilisation. Une fois les ponts cassés, le couvercle peut être refermé et rouvert plusieurs fois sans détériorer l'articulation : le couvercle est donc repositionnable.Thus, the present invention proposes a closure member intended to be mounted on an opening of a fluid reservoir, said member comprising a base body forming a fluid dispensing orifice, a mounting piece intended to be fixedly mounted. on the base body, and a closure cap for sealing the dispensing orifice, the cover being connected to the mounting part by a hinge, characterized in that the cover and the part are made integrally, the cover being initially connected to the mounting part, before first opening of the lid, by at least one bridge of breakable material during the first opening. This mounting piece serves as an intermediate piece or connection between the closure cover and the base body. Indeed, without this mounting part, it would not be possible to make breakable material bridges that keep the closure cover in the closed position before first use. Once the bridges are broken, the lid can be closed and reopened several times without damaging the joint: the lid is repositionable.

Selon une autre caractéristique intéressante de l'invention, le couvercle est inscrit à l'intérieur de la pièce de montage. Cela signifie que le couvercle est contenu dans l'encombrement de la pièce de montage. La pièce de montage peut se présenter sous la forme d'un anneau définissant un espace intérieur délimité par la circonférence interne de l'anneau et sa hauteur : le couvercle ne fait pas saillie vers le haut hors de cet espace interne. Ceci confère une configuration particulièrement plate à l'organe de bouchage. Avantageusement, ledit au moins un pont de matière s'étend radialement vers l'extérieur à partir de la périphérie externe du couvercle et relie la pièce de montage. Selon un autre aspect, le couvercle est séparé de la pièce de montage par des segments de fentes annulaires. Les segments de gentes entourent radialement le couvercle. Avantageusement, le couvercle forme un pointeau d'obturation engagé de manière étanche dans l'orifice de distribution du corps de base. Seule le pointeau d'obturation peut faire saillie vers le bas hors de l'espace interne de la pièce de montage.According to another advantageous characteristic of the invention, the lid is inscribed inside the mounting piece. This means that the cover is contained in the bulk of the mounting piece. The mounting piece may be in the form of a ring defining an interior space delimited by the inner circumference of the ring and its height: the lid does not protrude upwardly from this internal space. This confers a particularly flat configuration to the closure member. Advantageously, said at least one material bridge extends radially outwardly from the outer periphery of the cover and connects the mounting piece. In another aspect, the cover is separated from the mounting piece by annular slot segments. The segments of gentes radially surround the lid. Advantageously, the lid forms a sealing needle sealingly engaged in the dispensing orifice of the base body. Only the shutter needle can protrude downward from the internal space of the mounting piece.

Selon une caractéristique intéressante de l'invention, le corps, la pièce et le couvercle sont réalisés de manière monobloc, la pièce étant reliée au corps par une charnière, la pièce étant rapportée et fixée sur le corps. La charnière qui sert de liaison entre le corps et la pièce peut être conservée une fois l'organe de bouchage assemblé, ou au contraire retirée. En variante, il est bien entendu possible de mouler séparément d'un côté le corps et de l'autre côté une pièce de moulage incorporant la pièce de montage et le couvercle d'obturation. Ensuite, ces deux pièces sont apportées l'une sur l'autre pour constituer l'organe de bouchage en position fermée.According to an advantageous characteristic of the invention, the body, the part and the lid are made integrally, the part being connected to the body by a hinge, the part being attached and fixed on the body. The hinge which serves as a connection between the body and the workpiece can be kept once the closure member assembled, or otherwise removed. Alternatively, it is of course possible to mold separately on one side the body and on the other side a molding part incorporating the mounting piece and the closure cover. Then, these two parts are brought one on the other to form the closure member in the closed position.

Selon un autre aspect de l'invention, la pièce de montage définit une zone de scellage sensiblement plane destinée à venir en contact étanche avec l'ouverture du réservoir. Additionnellement ou en variante, le corps définit une zone de scellage sensiblement plane destinée à venir en contact étanche avec l'ouverture du réservoir. Ainsi, l'ouverture du réservoir peut être scellée et avantageusement soudée, soit sur la pièce de montage, soit sur le corps, ou encore entre la pièce de montage et le corps. La zone de scellage est sensiblement plane ou parfaitement plane de manière à pouvoir y souder une feuille souple définissant une ouverture délimitée par un bord périphérique plan. De cette manière, on peut utiliser l'organe de bouchage de l'invention avec un réservoir de produit fluide qui peut se présenter sous la forme d'une poche réalisée à partir d'une ou de deux feuille(s) souple(s), une des deux feuilles souples formant une ouverture dont le bord plan est soudé sur la zone de scellage de la pièce de montage et/ou du corps. On peut ainsi réaliser un distributeur de produit fluide uniquement constitué d'une poche souple scellée sur sa périphérie et d'un organe de bouchage monté sur une ouverture pratiquée sur une des faces de la poche. 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.According to another aspect of the invention, the mounting piece defines a substantially planar sealing zone intended to come into sealed contact with the opening of the reservoir. Additionally or alternatively, the body defines a substantially planar seal area for sealing engagement with the reservoir opening. Thus, the opening of the reservoir can be sealed and advantageously welded, either on the mounting piece or on the body, or between the mounting piece and the body. The sealing zone is substantially flat or perfectly flat so as to weld a flexible sheet defining an opening defined by a plane peripheral edge. In this way, it is possible to use the closure member of the invention with a fluid reservoir which can be in the form of a pocket made from one or two flexible sheet (s). one of the two flexible sheets forming an opening whose plane edge is welded to the sealing zone of the mounting piece and / or the body. It is thus possible to produce a fluid dispenser consisting solely of a flexible bag sealed on its periphery and a closure member mounted on an opening made on one of the faces of the bag. Such a dispenser may have a very small thickness of the order of 3 to 5 millimeters or less. The thickness of the dispenser is essentially constituted by the thickness of the closure member, since the flexible sheets have a non-significant thickness. Therefore, such a flat dispenser can be used as a fluid sample that can be inserted into the magazines of the press.

Selon une autre caractéristique de l'invention, la pièce définit une zone de contact périphérique continue et fermée destinée à venir en contact étanche avec le corps. La pièce de montage peut présenter une configuration annulaire fermée sur elle-même et le couvercle d'obturation est situé à l'intérieur de cette pièce annulaire en étant relié à cette pièce par une articulation et un ou deux pont(s) de matière cassable. La pièce annulaire peut ainsi être fixée sur le corps de base de manière étanche, par exemple par collage ou soudage. Le contact étanche peut s'étendre sur toute la périphérie de la pièce et du corps, de sorte que le produit fluide ne peut pas fuir entre le corps de base et la pièce de montage. Une technique appropriée de soudage est une technique de soudage aux ultrasons.According to another characteristic of the invention, the part defines a continuous and closed peripheral contact zone intended to come into sealed contact with the body. The mounting piece may have an annular configuration closed on itself and the closure cover is located inside this annular piece being connected to this piece by a hinge and one or two bridge (s) of breakable material . The annular piece can thus be fixed to the base body sealingly, for example by gluing or welding. The sealed contact may extend over the entire periphery of the workpiece and the body, so that the fluid can not leak between the base body and the mounting piece. An appropriate welding technique is an ultrasonic welding technique.

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. Avantageusement, l'ouverture est délimitée par un bord périphérique plan qui est scellé de manière étanche sur la pièce et/ou sur le corps. Ce bord périphérique plan peut être formé par la feuille souple ou encore par la coque thermoformée. Il faut bien noter que l'ouverture est réalisée dans une feuille, et non pas par le bord de deux feuilles soudées ensemble comme cela est généralement le cas avec les poches de l'art antérieur.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. Advantageously, the opening is delimited by a plane peripheral edge which is sealingly sealed to the workpiece and / or to the body. This flat peripheral edge may be formed by the flexible sheet or by the thermoformed shell. It should be noted that the opening is made in a sheet, and not by the edge of two sheets welded together as is generally the case with the pockets of the prior art.

Selon un autre aspect de l'invention, la feuille définit un côté intérieur destiné à venir en contact du produit fluide et un côté extérieur, l'organe de bouchage étant scellé sur le côté intérieur de la feuille. Avantageusement, cette opération de scellage de l'organe de bouchage est effectuée alors que la feuille souple ne constitue pas encore le réservoir de produit fluide. En d'autres termes, lorsque le réservoir de produit fluide est réalisé à partir d'une seule feuille repliée sur elle-même, l'organe de bouchage est scellé sur la feuille avant pliage de cette dernière.According to another aspect of the invention, the sheet defines an inner side for contacting the fluid and an outer side, the closure member being sealed on the inner side of the sheet. Advantageously, this Sealing operation of the closure member is performed while the flexible sheet does not yet constitute the fluid reservoir. In other words, when the fluid reservoir is made from a single sheet folded on itself, the closure member is sealed on the sheet before folding thereof.

La présente invention a également pour objet un procédé de fabrication d'un distributeur de produit fluide comprenant une étape de soudure unique au cours de laquelle la pièce de montage est soudée sur le corps et la feuille est soudée sur l'organe de bouchage. Ainsi, ces deux soudures sont effectuées simultanément à l'aide d'un ensemble de soudage unique, qui peut par exemple être un ensemble de soudage par ultrasons.The present invention also relates to a method of manufacturing a fluid dispenser comprising a single welding step in which the mounting piece is welded to the body and the sheet is welded to the closure member. Thus, these two welds are performed simultaneously with the aid of a single welding assembly, which may for example be an ultrasonic welding assembly.

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.

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 ou d'un autre 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 or another in a dispenser according to the present invention will be described in a second time.

L'organe de bouchage représenté sur les figures 1 à 6 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 sont réalisés de manière monobloc de manière à ne former qu'une seule pièce de moulage 2. Le couvercle 25 est relié à la pièce de base 20 par une articulation 26 qui peut se présenter sous la forme d'un pont de matière souple.The closure member represented on the Figures 1 to 6 has been designated as a whole by the letter C. It essentially comprises three constituent elements, namely a base body 1, a mounting piece 20 and a cover 25. The mounting piece 20 and the cover 25 are made integrally so as to form only one molding part 2. The cover 25 is connected to the base part 20 by a hinge 26 which may be in the form of a bridge of flexible material.

Le corps de base 1 se présente ici sous la forme d'une rondelle ou d'un disque comprenant une plage centrale 14 entourée par un bord annulaire périphérique 11. La plage 14 et le bord 11 définissent une surface de fond commune 13. Le bord 11 définit d'autre part une surface supérieure 12 qui est de préférence sensiblement ou parfaitement plane et annulaire. La plage centrale 14 fait saillie au niveau de sa périphérie extérieure par rapport à la surface supérieure 12 du bord périphérique 11. Ainsi, la plage 14 définit un rebord saillant 16 de forme annulaire. La surface supérieure de la plage centrale 14 forme une cuvette concave 15 qui est percée en son centre par un orifice de distribution 17 qui traverse la plage centrale 14 de part en part pour déboucher au niveau de la surface inférieure 13. La cuvette 15 va servir de récipient de récupération de produit fluide.The base body 1 is here in the form of a washer or disc comprising a central area 14 surrounded by a peripheral annular edge 11. The deck 14 and the edge 11 define a common bottom surface 13. The edge 11 defines on the other hand an upper surface 12 which is preferably substantially or perfectly flat and annular. The central area 14 protrudes at its outer periphery with respect to the upper surface 12 of the peripheral edge 11. Thus, the area 14 defines a projecting flange 16 of annular shape. The upper surface of the central zone 14 forms a concave bowl 15 which is pierced at its center by a dispensing orifice 17 which passes through the central zone 14 from one end to the other at the level of the lower surface 13. The bowl 15 will serve of fluid product recovery container.

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 ou de fond 13 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 geometrical shapes are conceivable, such as for example polygonal or oblong shapes. The bottom or bottom surface 13 of the base body is here perfectly flat: it can however be imagined that this surface 13 is made with any particular or particular profiles favoring for example the flow of fluid 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 toutes façons que cette pièce de montage soit adaptable sur le corps de base. La pièce de montage annulaire 20 comprend ici une zone de contact périphérique annulaire 22 définit par la surface inférieure de la pièce de montage. De l'autre côté, la pièce de montage forme un cordon annulaire saillant 23 au niveau de la périphérie interne de la pièce. Radialement vers l'extérieur de ce cordon 23, la surface supérieure de la pièce de montage 20 forme une zone de scellage plane de forme sensiblement ou parfaitement annulaire. Cette zone de scellage 21 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. It is necessary in any case that this mounting piece is adaptable to the basic body. The annular mounting piece 20 here comprises an annular peripheral contact area 22 defined by the lower surface of the mounting piece. On the other side, the mounting piece forms a projecting annular bead 23 at the inner periphery of the workpiece. Radially outwardly of this bead 23, the upper surface of the mounting piece 20 forms a planar sealing zone of substantially or perfectly annular shape. This sealing zone 21 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 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 25 est relié à la périphérie interne de la pièce de montage, et plus précisément au niveau du cordon saillant 23, par une articulation souple 26, mais également par un ou plusieurs pont(s) de matière 28, comme on peut le voir sur les figures 3, 4 et 5. La surface supérieure du couvercle 25 peut être située dans le même plan que le haut du cordon saillant 23. Ainsi, le bord périphérique extérieur du couvercle 25 est séparé du cordon saillant 23 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. Hormis le pointeau, 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 integrally formed with the mounting piece 20, also has a disc or washer shape which is disposed within the mounting piece 20, as can be seen in the figures. The cover 25 is connected to the inner periphery of the mounting piece, and more precisely to the projecting bead 23, by a flexible joint 26, but also by one or more bridge (s) of material 28, as can be seen on the Figures 3, 4 and 5 . The upper surface of the cover 25 may be located in the same plane as the top of the projecting bead 23. Thus, the outer peripheral edge of the cover 25 is separated from the projecting bead 23 by segments of annular slots 29 separated by the material bridges 28. and the flexible hinge 26. In its center, the lid 25 defines a closure needle 27 which extends from the bottom surface of the lid. Aside from the needle, the lid is fully inscribed in the size of the mounting piece. The needle can also be eccentric if the dispensing orifice 17 is also eccentric.

A l'état monté, comme représenté sur les figures 1 et 2, la pièce de montage 20 est rapportée sur le corps de base 1 de telle sorte que la zone de contact 22 de la pièce de montage 20 vient en contact avec la surface supérieure 22 du bord périphérique 12 du corps de base 1. Avantageusement, le contact entre la zone 22 et la surface 12 est étanche sur la totalité de la périphérie. Ce contact étanche peut être réalisé par n'importe quel moyen approprié, comme par exemple par serrage étanche, encliquetage étanche, collage ou soudage. Une technique de soudage par ultrasons est particulièrement bien appropriée. On peut remarquer sur les figures 1 et 2 que la pièce de montage 20 vient se loger étroitement autour du rebord saillant 16 formé par la plage centrale 14. Avantageusement, le diamètre externe de la pièce de montage 20 est identique au diamètre externe du corps de base 1. Une fois la pièce de montage 20 ainsi rapportée sur le corps de base 1, le couvercle 25 peut pivoter autour de l'articulation 26 entre une position ouverte, telle que représentée sur la figure 2, et une position fermée, telle que représentée sur la figure 1 dans laquelle le pointeau d'obturation 27 est engagé de manière étanche dans l'orifice de distribution 17 du corps de base 1. Le couvercle peut être rouvert et refermé à volonté sans casser l'articulation 26.In the assembled state, as shown in Figures 1 and 2 , the mounting piece 20 is attached to the base body 1 so that the contact area 22 of the mounting piece 20 comes into contact with the upper surface 22 of the peripheral edge 12 of the base body 1. Advantageously, the contact between the zone 22 and the surface 12 is sealed over the entire periphery. This sealed contact can be made by any suitable means, such as for example by tight sealing, snap sealing, bonding or welding. An ultrasonic welding technique is particularly well suited. We can notice on Figures 1 and 2 that the mounting piece 20 is housed tightly around the protruding flange 16 formed by the central area 14. Advantageously, the outer diameter of the mounting piece 20 is identical to the outer diameter of the base body 1. Once the mounting piece As reported on the base body 1, the cover 25 is pivotable about the hinge 26 between an open position, as shown in FIG. figure 2 , and a closed position, as shown on the figure 1 in which the sealing needle 27 is sealingly engaged in the dispensing orifice 17 of the basic body 1. The lid can be reopened and closed again at will without breaking the articulation 26.

Cependant, 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.However, when the closure member C has just been assembled, as shown in FIG. figure 1 , the cover 25 is connected to the mounting piece 20 not only by the flexible joint 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.

Il faut bien noter qu'un tel organe de bouchage C n'est réalisable qu'en trois parties distinctes, à savoir un corps 1, une pièce de montage 20 et un couvercle 25 même si ces pièces peuvent être réalisées de manière monobloc. En effet, il ne serait pas possible, pour des raisons techniques de moulage, de relier directement le couvercle 25 au corps de base 1 par une articulation souple 26 et des ponts de matière cassants 28. Cette configuration particulière est rendue possible par l'utilisation d'une pièce de montage intermédiaire 20 qui fait la liaison entre le corps de base 1 et le couvercle 25. Cette pièce de montage 20 peut être réalisée de manière monobloc avec le couvercle 25 en étant reliés ensemble par l'articulation souple 26 et les ponts de matière cassants 28. Cette pièce de montage 20 est ensuite rapportée et fixée en place sur le corps de montage 1, de préférence de manière étanche. Le corps de base 1 et la pièce de moulage 2 formés par la pièce de montage 20 et le couvercle 25 peuvent être réalisés en deux pièces, comme représenté sur les figures 4, 5 et 6, ou en variante, le corps 1 et la pièce de moulage 2 peuvent être réalisés de manière monobloc en étant reliés par une charnière 24, comme représenté sur la figure 3. Les deux pièces peuvent alors être rapportées l'une sur l'autre en déformant la charnière 24.It should be noted that such a closure member C is only feasible in three distinct parts, namely a body 1, a mounting piece 20 and a cover 25 even if these parts can be made in one piece. Indeed, it would not be possible, for technical reasons of molding, to directly connect the cover 25 to the base body 1 by a flexible joint 26 and bridges of brittle material 28. This particular configuration is made possible by the use of an intermediate mounting piece 20 which makes the connection between the base body 1 and the cover 25. This mounting piece 20 can be made in one piece with the cover 25 being connected together by the flexible joint 26 and the bridges of brittle material 28. This mounting piece 20 is then attached and fixed in place on the mounting body 1, preferably sealingly. The base body 1 and the molding part 2 formed by the mounting part 20 and the cover 25 can be made in two parts, as shown in the drawings. Figures 4, 5 and 6 or alternatively, the body 1 and the molding part 2 can be made integrally by being connected by a hinge 24, as shown in FIG. figure 3 . The two pieces can then be attached to one another by deforming the hinge 24.

On peut également remarquer que l'organe de bouchage C de la présente invention présente une épaisseur très réduite de l'ordre de 2 à 5 millimètres. Ceci est rendu possible du fait que la pièce de montage 20 s'emboîte légèrement à l'intérieur du corps de base 1 (autour du rebord 16) et du fait que le couvercle 25 est disposé à l'intérieur de la pièce de montage 20 sans en faire saillie vers le haut. Ainsi, l'épaisseur de l'organe de bouchage C correspond grossièrement à la hauteur du pointeau d'obturation 27 du couvercle 25.It may also be noted that the closure member C of the present invention has a very reduced thickness of the order of 2 to 5 millimeters. This is made possible because the mounting piece 20 fits slightly inside the base body 1 (around the flange 16) and because the cover 25 is disposed within the mounting piece 20 without projecting upward. Thus, the thickness of the closure member C corresponds roughly to the height of the closure needle 27 of the cover 25.

On se référera maintenant aux figures 7 et 8 pour décrire en détail un procédé de fabrication avantageux d'un distributeur de produit fluide susceptible d'intégrer un organe de bouchage C tel que décrit en référence aux figures 1 à 6. Le distributeur de produit fluide qui va être décrit peut également intégrer un autre type d'organe de bouchage. Toutefois, nous considérerons dans la suite de cette description que l'organe de bouchage utilisé dans les figures 7 et 8 est celui des figures 1 à 6.We will now refer to Figures 7 and 8 to describe in detail an advantageous manufacturing process of a fluid dispenser capable of integrating a closure member C as described with reference to Figures 1 to 6 . The fluid dispenser that will be described may also incorporate another type of closure member. However, we will consider in the remainder of this description that the closure member used in the Figures 7 and 8 is that of Figures 1 to 6 .

La figure 7 est une vue qui montre de manière très schématique les différentes étapes de fabrication a, b, c, d, e, f, g et h mises en oeuvre dans un procédé de fabrication d'un distributeur de produit fluide selon l'invention. Le procédé de fabrication utilise comme matière première une bande continue de feuille souple 3 et des organes de bouchage C. Pour travailler ces matières premières, le procédé de fabrication de l'invention utilise également des outils, comme par exemple un poinçon 4 ou un ensemble de soudage (figure 8).The figure 7 is a view which shows very schematically the various manufacturing steps a, b, c, d, e, f, g and h implemented in a method of manufacturing a fluid dispenser according to the invention. The manufacturing method uses as a raw material a continuous strip of flexible sheet 3 and capping members C. To work these raw materials, the manufacturing method of the invention also uses tools, such as a punch 4 or a set welding ( figure 8 ).

La bande de feuille souple 3 est initialement plane et peut être déroulée à partir d'un rouleau. La feuille 3 présente ainsi une largeur déterminée. Lorsque l'on regarde la figure 7, on peut voir que la feuille 3 est parfaitement plane dans les étapes a et b, en cours de pliage dans la étapes c et d et complètement repliée sur elle-même dans les étapes e, f, g et h. Le déroulement du procédé de fabrication selon l'invention se lit de gauche à droite sur la figure 7 en commençant par l'étape a. Ainsi, une fois la bande de feuille souple 3 déroulée de son rouleau, elle parvient jusqu'à un premier poste de poinçonnage ou de découpe au niveau duquel la feuille est découpée à l'aide d'un outil de poinçonnage 4 de manière à former une ouverture 31, qui est ici de forme circulaire. Il est à noter que cette opération de poinçonnage est réalisée alors que la feuille 3 est plane, c'est-à-dire exempte de toute pliure. Le bord 32 de l'ouverture est donc sensiblement ou parfaitement plan et fait le tour de l'ouverture.The flexible sheet web 3 is initially planar and can be unwound from a roll. The sheet 3 thus has a determined width. When we look at the figure 7 it can be seen that sheet 3 is perfectly flat in steps a and b, being folded in steps c and d and completely folded back on itself in steps e, f, g and h. The course of the manufacturing process according to the invention is read from left to right on the figure 7 starting with step a. Thus, once the flexible sheet web 3 unwraps from its roll, it reaches a first punching station or cutting at which the sheet is cut with a punching tool 4 so as to form an opening 31, which is here circular. It should be noted that this punching operation is performed while the sheet 3 is flat, that is to say free of any fold. The edge 32 of the opening is substantially or perfectly flat and around the opening.

Dans la seconde étape b, la feuille 3 est toujours plane, et l'on procède alors au montage de l'organe de bouchage C au niveau de l'ouverture 31 de la feuille 3.In the second step b, the sheet 3 is always flat, and then one proceeds to the mounting of the closure member C at the opening 31 of the sheet 3.

Une fois l'organe de bouchage C en place sur la feuille 3 toujours plane, on procède dans l'étape c à la fixation de l'organe de bouchage C dans l'ouverture 31, par exemple à l'aide d'une technique de soudage, par exemple par ultrasons. Il est à noter que l'organe de bouchage C est mis en place sur la feuille 3 avec son couvercle orienté vers le bas et sa surface de fond 13 orientée vers le haut.Once the closure member C in place on the sheet 3 always flat, proceed in step c to the fixing of the closure member C in the opening 31, for example using a technique welding, for example by ultrasound. It should be noted that the closure member C is placed on the sheet 3 with its lid facing downwards and its bottom surface 13 facing upwards.

Au cours de l'étape d, la feuille 3 est repliée sur elle-même de sorte que l'organe de bouchage C est visible de son autre face.During step d, the sheet 3 is folded back on itself so that the closure member C is visible from its other face.

Au niveau de l'étape e, l'opération de pliage est terminée : la feuille 3 est alors repliée sur elle-même en formant deux pans reliés par le bord inférieur.In step e, the folding operation is completed: the sheet 3 is then folded on itself, forming two panels connected by the lower edge.

Au cours de l'étape f, la feuille repliée est soudée sur deux ou trois côtés, étant donné que la soudure du bord inférieure est optionnelle, puisque la feuille 3 est continue à ce niveau. Les soudures S ont pour résultat de souder ensemble les deux pans formés par la feuille repliée 3. Au résultat, on obtient une petite poche P délimitée par au moins deux soudures latérales verticales S et un bord inférieur soudé ou non. L'organe de bouchage C est situé sur un des deux pans de la feuille repliée, à distance des soudures S.In step f, the folded sheet is welded on two or three sides, since the bottom edge weld is optional, since the sheet 3 is continuous at this level. The welds S result in welding together the two panels formed by the folded sheet 3. As a result, there is obtained a small pocket P defined by at least two vertical side welds S and a lower edge welded or not. The closure member C is located on one of the two sides of the folded sheet, away from the S welds.

Au cours de l'étape g, la poche P est remplie de produit fluide F par le côté de la poche P qui n'est pas encore soudé. Pour cela, il suffit de faire entrebâiller la poche P de manière à créer une ouverture.During step g, the pocket P is filled with fluid product F by the side of the pocket P which is not yet welded. For this, simply open the pocket P to create an opening.

Ensuite, l'étape h consiste à terminer la soudure de la poche P au niveau du côté par lequel le remplissage de produit fluide F a été effectué à l'étape g. Ainsi, le produit fluide F contenu dans la poche P est isolé de l'extérieur par les soudures périphériques S. Sa seule sortie possible est par l'organe de bouchage C qui est encore fermé.Then, step h consists in completing the welding of the pocket P at the side by which the filling of fluid product F has been carried out in step g. Thus, the fluid product F contained in the pocket P is isolated from the outside by the peripheral welds S. Its only possible outlet is through the closure member C which is still closed.

La dernière étape de fabrication consiste à détacher chaque poche P de manière à définir un distributeur de produit fluide D.The last manufacturing step consists of detaching each pocket P so as to define a fluid dispenser D.

Il faut noter dans ce procédé de fabrication que l'organe de bouchage C est monté sur la feuille souple 3 avant la formation de la poche P, et même avant pliage de la feuille souple. En effet, l'organe de bouchage C est monté sur la feuille 3 alors que celle-ci est encore plane, c'est-à-dire exempte de toute pliure servant à réaliser une poche.It should be noted in this manufacturing process that the closure member C is mounted on the flexible sheet 3 before the formation of the pocket P, and even before folding of the flexible sheet. Indeed, the closure member C is mounted on the sheet 3 while it is still flat, that is to say free of any fold used to make a pocket.

On peut également remarquer que l'organe de bouchage C est monté de l'intérieur, c'est-à-dire sur le côté intérieur 3i de la feuille 3 qui va ensuite former les parois internes de la poche.It can also be noted that the closure member C is mounted from the inside, that is to say on the inner side 3i of the sheet 3 which will then form the inner walls of the pocket.

Cette technique de fixation de l'organe de bouchage sur la feuille 3, alors que celle-ci est encore à plat, et de surcroît sur le côté 3i formant l'intérieur de la poche, facilite considérablement le procédé de fabrication du distributeur de produit fluide. En effet, il est bien plus facile de monter un organe de bouchage sur une feuille plane qu'à l'intérieur d'une poche déjà formée et remplie de produit fluide.This technique of fixing the closure member on the sheet 3 while it is still flat, and moreover on the side 3i forming the inside of the bag, greatly facilitates the manufacturing process of the product dispenser fluid. Indeed, it is much easier to mount a closure member on a flat sheet inside a pocket already formed and filled with fluid.

La figure 8 montre plus en détail la mise en oeuvre de l'étape c au cours de laquelle l'organe de bouchage C est monté sur l'ouverture 31 de la feuille souple 3. Cette étape utilise un ensemble de soudage qui est schématisé par les deux mâchoires 5 sur la figure 8. Il peut par exemple s'agir des mâchoires d'un ensemble de soudage par ultrasons comprenant une enclume et une sonotrode. La figure 8 montre également le détail de l'organe de bouchage C, qui est celui des figures 1 à 6. On peut identifier le corps de base 1 et la pièce de moulage 2 incorporant la pièce de montage 20 et le couvercle 25. Selon une forme de réalisation préférée, le bord 32 de l'ouverture 31 est soudé sur la périphérie externe de la pièce de montage 20 au niveau de la zone de scellage 21. En réalité, la figure est une représentation à l'envers par rapport à l'étape c représentée sur la figure 7. En effet, alors que la feuille 3 est représentée dans l'étape c de la figure 7 sur son côté intérieur 3i formant ensuite l'intérieur de la poche P, la feuille 3 sur la figure 8 est représentée avec son côté intérieur orienté vers le bas et son côté extérieur 3e orienté vers le haut. Une fois la feuille 3 repliée sur elle-même, le corps de base 1 va être situé à l'intérieur de la poche, seuls le couvercle 25 et le cordon saillant 23 étant visible à travers l'ouverture 31 de la feuille.The figure 8 shows in greater detail the implementation of step c during which the closure member C is mounted on the opening 31 of the flexible sheet 3. This step uses a welding assembly which is schematized by the two jaws 5 on the figure 8 . It may for example be the jaws of an ultrasonic welding assembly comprising an anvil and a sonotrode. The figure 8 also shows the detail of the closure member C, which is that of Figures 1 to 6 . It is possible to identify the base body 1 and the molding part 2 incorporating the mounting piece 20 and the cover 25. According to a preferred embodiment, the edge 32 of the opening 31 is welded to the outer periphery of the piece of 20. In reality, the figure is a representation in reverse with respect to step c shown in FIG. figure 7 . Indeed, while the sheet 3 is represented in step c of the figure 7 on its inner side 3i then forming the inside of the pocket P, the sheet 3 on the figure 8 is shown with its inner side facing downwards and its outer side 3rd facing upwards. Once the sheet 3 folds back on itself, the base body 1 will be located inside the pocket, only the cover 25 and the bead 23 being visible through the opening 31 of the sheet.

En variante, il est également possible de souder le bord 32 de l'ouverture de la feuille 3 sous le corps de base 1 c'est-à-dire contre la surface de fond 13 ou encore entre le corps de base 1 et la pièce de moulage 2. Ceci est représenté sur la figure 8 avec la feuille 3 illustrée en traits pointillés. On peut par exemple se servir de la feuille 3 comme interface de liaison ou de soudage entre le corps de base 1 et la pièce de moulage 2.Alternatively, it is also possible to weld the edge 32 of the opening of the sheet 3 under the base body 1 that is to say against the bottom surface 13 or between the base body 1 and the workpiece 2. This is shown on the figure 8 with the sheet 3 illustrated in dashed lines. For example, the sheet 3 may be used as a bonding or welding interface between the base body 1 and the molding part 2.

Selon une autre caractéristique intéressante de l'invention, la pièce de moulage 2 incorporant la pièce de montage 20 et le couvercle 25 est fixée sur le corps de base 1 en même temps que l'on fixe la feuille 3 sur l'organe de bouchage C. Selon une forme de réalisation avantageuse, l'ensemble de soudage 5 soude simultanément la feuille 3 sur l'organe de bouchage C et la pièce de moulage 2 sur le corps de base 1. Deux soudures distinctes sont ainsi réalisées au cours d'une seule et même opération à l'aide d'un seul et unique ensemble de soudage.According to another advantageous characteristic of the invention, the molding part 2 incorporating the mounting piece 20 and the cover 25 is fixed on the base body 1 at the same time as the sheet 3 is fixed on the closure member C. According to an advantageous embodiment, the welding assembly 5 simultaneously welds the sheet 3 on the closure member C and the molding part 2 on the basic body 1. Two separate welds are thus produced in one and the same operation by means of a single welding assembly.

Le procédé de fabrication qui vient d'être décrit utilise avantageusement, mais pas exclusivement, un organe de bouchage C tel que décrit et représenté sur les figures 1 à 6. Toutefois, on peut utiliser un autre type d'organe de bouchage dans le procédé de fabrication selon l'invention.The manufacturing method which has just been described advantageously uses, but not exclusively, a closure member C as described and shown in FIGS. Figures 1 to 6 . However, another type of closure member may be used in the manufacturing method according to the invention.

La feuille souple 3 peut être réalisée à partir de n'importe quels matériaux appropriés, et peut par exemple se présenter sous la forme d'un film complexe métal/plastique. La feuille souple 3 doit permettre de fabriquer une poche P qui n'a pas ou sensiblement pas de mémoire de forme. En d'autres termes, lorsque l'on déforme la poche P, elle va rester dans l'état déformé.The flexible sheet 3 may be made from any suitable material, and may for example be in the form of a metal / plastic complex film. The flexible sheet 3 must make it possible to manufacture a pocket P which has no or substantially no shape memory. In other words, when the pocket P is deformed, it will remain in the deformed state.

Grâce aux caractéristiques de l'invention, on peut aisément fabriquer à moindre coût un distributeur de produit fluide D 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 D qui présente une épaisseur minimale qui correspond sensiblement à l'épaisseur de l'organe de bouchage qui est de l'ordre de 2 à 5 millimètres. On peut de ce fait insérer le distributeur D 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 D 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. Finally, there is obtained a distributor D which has a minimum thickness which substantially corresponds to the thickness of the closure member which is of the order of 2 to 5 millimeters. Thus, distributor D can be inserted in magazines as an advertising sample.
