Description

DISPOSITIF DE BOUCHON A CHARNIERE POUR FERMETURE D'UN RECIPIENT COMME UNE BOUTEILLE, FLACON OU ANALOGUE. HINGE CAP DEVICE FOR CLOSING A CONTAINER SUCH AS A BOTTLE, BOTTLE OR THE LIKE.
L'invention a pour objet un dispositif de bouchon à charnière pour fermeture d'un récipient comme une bouteille, flacon ou analogue.The invention relates to a hinged stopper device for closing a container such as a bottle, flask or the like.
On connaît déjà de nombreux dispositifs de fermeture pour récipients comme des bouteilles, des flacons, des tubes ou analogues constitués par un bouchon à charnière c'est-à- dire un dispositif moulé d'une pièce en matière plastique comportant une première partie munie d'une ouverture de sortie et destinée à être fixée au récipient et une seconde partie ou coiffe reliée à la première partie par une charnière-film en ladite matière plastique, par exemple du polypropylène dont l'excellente résistance à la flexion permet la réalisation de charnières extrêmement robustes susceptibles de subir un très grand nombre de pliages sans aucune altération notable. Lorsqu'on souhaite, complé entairement, commander l'ouverture et/ou la fermeture du dispositif par un action- ne ent simple, de préférence à l'aide d'une seule main, on prévoit que l'ouverture et/ou la fermeture s'effectue avec un effet de "ressort" c'est-à-dire de manière qu'elle se pour- suive drelle même après qu'elle ait été initiée par l'utili¬ sateur et après qu'ait été franchi un "point mort" lors du pivotement de la coiffe autour de ladite charnière.Numerous closure devices are already known for containers such as bottles, flasks, tubes or the like constituted by a hinged stopper, that is to say a device molded from a plastic part comprising a first part provided with '' an outlet opening and intended to be fixed to the container and a second part or cap connected to the first part by a film hinge in said plastic material, for example polypropylene whose excellent resistance to bending allows the production of hinges extremely robust likely to undergo a very large number of folds without any notable alteration. When it is desired, additionally, to control the opening and / or closing of the device by a simple action, preferably with one hand, provision is made for the opening and / or closing is carried out with a "spring" effect, that is to say in such a way that it follow d r itself after it has been initiated by the utili¬ sateur and may have been passed after a "neutral" during pivoting of the cap about said hinge.
Des dispositifs de bouchon à charnière pour ferme- ture de récipients de ce type sont divulgués, par exemple, dans FR-A-2 380 195, où les moyens constitutifs de la charnière proprement dite sont relativement volumineux et en saillie importante par rapport à la surface externe du dispositif ce qui écarte leur utilisation pour certaines applications, par exemple pour la fermeture de récipients du type de ceux uti¬ lisés pour le conditionnement de produits pharmaceutiques, cosmétiques, ou analogues. En outre, les réalisations décrites comportent des moyens de blocage de la coiffe par rapport à la partie fixée au récipient, de sorte que si elles sont appropriées pour s'opposer à l'ouverture non voulue, par des enfants, du récipient qu'elles équipent, elles sont d'une structure trop complexe pour être associées à des récipients pour lesquels la condition qui vient d'être rappelée est moins impérative. C'est, d'une façon générale, un but de l'invention de fournir un dispositif de bouchon à charnière pour ferme¬ ture de récipients comme des bouteilles, flacons, tubes ou analogues, qui pallie les inconvénients évoqués ci-dessus des dispositifs connus. C'est, également, un but de l'invention de fournir un tel dispositif dont la fabrication soit suffisamment sirtple, par les techniques de moulage par injection, pour ne pas gre¬ ver de façon importante le prix de revient et, ainsi son exploitation industrielle et/ou commerciale. Un dispositif de bouchon à charnière selon l'inven¬ tion, comprenant une première partie munie d'une ouverture de sortie et propre à être fixée au récipient et une seconde partie ou coiffe munie de moyens d'obturation de ladite ouver¬ ture et reliée à ladite première partie par une charnière- film avec effet élastique est caractérisé en ce que la charnière-film, unique, comprend des zones d'extrémités, - considérées suivant la direction axiale de la charnière -, qui sont conformées suivant des portions de surfaces sphérique On entend ici, par charnière-film, une articulatio dont les deux parties mobiles l'une par rapport à l'autre so reliées entre elles par une mince épaisseur ou film de matiè plastique, qui ménage l'axe de pivotement, comme d'ailleurs usuel dans la technique des bouchons, des reliures ou des boîtes pliantes moulées d'une seule pièce qui font applicati de telles charnières.Hinged stopper devices for closing containers of this type are disclosed, for example, in FR-A-2 380 195, where the means constituting the hinge itself are relatively bulky and projecting considerably from the external surface of the device, which precludes their use for certain applications, for example for closing containers of the type of those used for packaging pharmaceuticals, cosmetics, or the like. In addition, the embodiments described include means for blocking the cap relative to the part fixed to the container, so that if they are suitable for opposing the unwanted opening, by children, of the container that they equip, they are of a structure too complex to be associated with containers for which the condition which has just been recalled is less imperative. It is, in general, an object of the invention to provide a hinged stopper device for closing containers such as bottles, flasks, tubes or the like, which overcomes the drawbacks mentioned above of the devices. known. It is also an object of the invention to provide such a device, the manufacture of which is sufficiently simple, by injection molding techniques, so as not to significantly reduce the cost price and thus its use. industrial and / or commercial. A hinged plug device according to the invention, comprising a first part provided with an outlet opening and suitable for being fixed to the container and a second part or cap provided with means for closing said opening and connected to said first part by a film hinge with elastic effect is characterized in that the film hinge, unique, includes end zones, - considered in the axial direction of the hinge -, which are shaped according to spherical surface portions Here we mean, by film hinge, an articulation whose two movable parts l 'one with respect to the other so interconnected by a thin thickness or film of plastic material, which spares the pivot axis, as is usual in the technique of caps, bindings or folding boxes molded from a single piece that makes such hinges apply
Selon une autre caractéristique de l'invention, la zone médiane comprise entre lesdites portions de surfaces sphériques est à contour plan sensiblement rectangulaire, à longs côtés dirigés parallèlement à l'axe de la charnière. Dans une réalisation préférée les portions de surfa ces sphériques sont limitées par un plan sensiblement paral¬ lèle au bord libre de la coiffe, dans la condition de moulage du dispositif, tandis que ledit plan fait un angle de sensi¬ blement 90° par rapport à sa condition de moulage, dans la condition de fermeture du dispositif.According to another characteristic of the invention, the middle zone between said portions of spherical surfaces has a substantially rectangular plane outline, with long sides directed parallel to the axis of the hinge. In a preferred embodiment, the portions of these spherical surfaces are limited by a plane substantially parallel to the free edge of the cap, in the condition of molding of the device, while said plane makes an angle of appreciably 90 ° relative to its molding condition, in the closing condition of the device.
L'épaisseur du film constitutif de la charnière est la même, dans la zone médiane et dans les zones d'extrémités.The thickness of the film constituting the hinge is the same, in the middle zone and in the end zones.
En variante, le film est d'épaisseur variable, avantageusement plus épais dans la zone médiane que dans les zones d'extrémités en partie sphériques.As a variant, the film is of variable thickness, advantageously thicker in the middle zone than in the partly spherical end zones.
Dans une réalisation particulièrement préférée la première partie fixée au récipient comprend une lèvre d'extré¬ mité et la zone médiane de la charnière est reliée sur une des faces à la paroi latérale de la coiffe et à la paroi laté- raie de ladite lèvre par des arrondis tandis que la liaison de ladite zone auxdites parois a lieu par des chanfreins sur son autre face.In a particularly preferred embodiment, the first part fixed to the container comprises an end lip and the central zone of the hinge is connected on one of the faces to the side wall of the cap and to the side wall of said lip by rounded while the connection of said zone to said walls takes place by chamfers on its other face.
L'invention sera bien comprise par la description qui suit, faite à titre d'exemple et en référence au dessin annexé dans lequel : - la figure 1 est une vue partie en coupe, partie en élévation de dessus, d'un dispositif de bouchon selon l'in¬ vention dans sa condition d'ouverture totale ;The invention will be better understood from the following description, given by way of example and with reference to the appended drawing in which: - Figure 1 is a view partly in section, partly in elevation from above, of a plug device according to the invention in its fully open condition;

- la figure 6 en est une vue partielle, en coupe, et à plus grande échelle.- Figure 6 is a partial view, in section, and on a larger scale.
Le dispositif de bouchon selon l'invention, pour la fermeture d*un récipient comme une bouteille, un flacon, ou un tube, T, figure 2, comprend essentiellement une première partie 11 destinée à être fixée sur le récipient T par vis¬ sage d'une jupe 12 sur l'embout e du tube et une seconde partie ou coiffe 13 reliée à la première partie par une char- nière 14 du type "charnière-film" c'est-à-dire réalisée par une zone de faible épaisseur de la matière plastique consti¬ tutive du dispositif, par exemple du polypropylène dont l'excellente résistance à la flexion permet la réalisation de ce type de charnière. La jupe 12, qui présente sur sa surface externe deux nervures 12a et 12b diamétralement opposées formant butées, dépend d'une calotte tronconique 15 dont la base de plus petit diamètre est percée d'une ouverture 16 de passage du produit contenu dans le récipient T, tandis qu'à la base de plus grand diamètre se raccorde une paroi 17 à très faible conicité 17 dont la partie d'extrémité libre est reliée par un épaulement 18 à une lèvre cylindrique à section droite circulaire 19. La coiffe 13 est conformée suivant une cuvette tronconique à très faible conicité également et dont le profil de la face interne de la paroi latérale 20 est conjugué de celui de la paroi 17, tandis que le diamètre externe du bord libre 20a correspond à celui de la lèvre 19. Un fond 21, lé¬ gèrement bombé vers l'intérieur de la cuvette,porte en son centre un téton 22 de forme et dimensions conjuguées de l'ou¬ verture 16 qu'il est destiné à obturer dans la condition de fermeture du dispositif.The stopper device according to the invention, for closing a container like a bottle, a flask or a tube, T, FIG. 2, essentially comprises a first part 11 intended to be fixed to the container T by screws. a skirt 12 on the end piece e of the tube and a second part or cap 13 connected to the first part by a hinge 14 of the "film hinge" type, that is to say made by a zone of weak thickness of the consti¬ tutive plastic of the device, for example polypropylene, the excellent flexural strength of which enables this type of hinge to be produced. The skirt 12, which has on its outer surface two diametrically opposite ribs 12a and 12b forming stops, depends on a frustoconical cap 15 whose base of smaller diameter is pierced with an opening 16 for passage of the product contained in the container T , while at the base of larger diameter is connected a wall 17 with very small conicity 17 whose free end part is connected by a shoulder 18 to a cylindrical lip with circular cross section 19. The cap 13 is shaped as follows a frustoconical bowl with very low taper also and whose profile of the internal face of the side wall 20 is conjugated with that of the wall 17, while the external diameter of the free edge 20a corresponds to that of the lip 19. A bottom 21, slightly curved inwardly of the bowl , carries in its center a stud 22 of combined shape and dimensions of the opening 16 which it is intended to close in the closed condition of the device.
La charnière 14, illustrée avec plus de précision su les figures 3 à 6, est ménagée à la périphérie de la lèvre 19 et au voisinage de l'extrémité de la paroi 20 distante du fon 21. Selon l' invention,1a charnière-film 14 comprend une zone médiane 30, figures 1, 3 et 5 sensiblement plane et à contour quelque peu rectangulaire avec de longs côtés 32, 33 dirigés tangentiellement aux surfaces cylindriques ou quasi cylindri- ques constitutives de la lèvre 19 et de la paroi 20 et de petits côtés parallèles au plan de symétrie d'ensemble du dispositif, tel que montré par la ligne II-II de la figure 1.The hinge 14, illustrated more precisely in FIGS. 3 to 6, is formed at the periphery of the lip 19 and in the vicinity of the end of the wall 20 distant from the fon 21. According to the invention, the film hinge 14 comprises a central zone 30, FIGS. 1, 3 and 5 substantially planar and with a somewhat rectangular outline with long sides 32, 33 directed tangentially to the cylindrical or almost cylindrical surfaces constituting the lip 19 and the wall 20 and short sides parallel to the overall plane of symmetry of the device, as shown by line II-II in Figure 1.
A cette zone médiane 30 se raccordent aux extrémités longitudinales du rectangle (dont la direction des longs cotés définit l'axe de la charnière) des zones 35 et 36 conformées suivant des portions de surfaces sphériques limitées par un plan parallèle à celui du bord libre 20a de la coiffe 13, dans la condition de moulage du dispositif, et dont le rayon est légèrement supérieur à la largeur de la zone médiane 30 dans le plan de symétrie II-II du dispositif.To this central zone 30 are connected to the longitudinal ends of the rectangle (the direction of the long sides of which defines the axis of the hinge) zones 35 and 36 shaped according to portions of spherical surfaces bounded by a plane parallel to that of the free edge 20a of the cap 13, in the molding condition of the device, and whose radius is slightly greater than the width of the middle zone 30 in the plane of symmetry II-II of the device.
Dans une forme de réalisation les zones 35, 36 ont la même épaisseur que celle de la zone 30.In one embodiment, the zones 35, 36 have the same thickness as that of the zone 30.
En variante, les zones 35 et 36 sont de plus faible épaisseur que la zone 30. Cette dernière, comme bien visible sur les figuresAs a variant, zones 35 and 36 are thinner than zone 30. The latter, as clearly visible in the figures
2, 4 et 6 se raccorde à la face externe de la paroi 20 par un arrondi 40, à la face externe de la lèvre 19 par un même ar¬ rondi 41 et par des chanfreins 43 et 44 au bord libre 20a de la coiffe 13, d'une part et, à la face 45 de l'épaulement 18 q^ est sensiblement coplanaire audit bord libre dans la con- dition d'ouverture à 180e du dispositif du bouchon, qui est celle montrée sur les figures 1 et 2, d'autre part.2, 4 and 6 is connected to the external face of the wall 20 by a rounded 40, to the external face of the lip 19 by the same rounded ar¬ 41 and by chamfers 43 and 44 to the free edge 20a of the cap 13 , on the one hand and, on the face 45 of the shoulder 18 q ^ is substantially coplanar with said free edge in the con- dition opening 180 e of the plug device, which is that shown in Figures 1 and 2, on the other hand.
Selon l'invention, le moulage du dispositif par injection de polypropylène a lieu à partir de la partie 10, de sorte qu'une résistance élevée est obtenue pour la charnière, tant dans sa zone médiane 30 que dans ses zones d'extrémité en partie sphériques, ces dernières contribuant à la supression de tout phénomène d'entaille préjudiciable à la résistance du dispositif laquelle est encore accrue par l'orientation des molécules constitutives de la matière moulée.According to the invention, the injection molding of the polypropylene device takes place from the part 10, so that a high resistance is obtained for the hinge, both in its central zone 30 and in its end zones in part. spherical, the latter contributing to the suppression of any notch phenomenon detrimental to the resistance of the device which is further increased by the orientation of the constituent molecules of the molded material.
Lorsque, à partir de la condition montrée sur les figures 1 et 2, la coiffe 13 est amenée à pivoter autour de la charnière 14 par actionnement dans le sens de la flèche f_ jusqu'à ce que le récipient T soit obturé par coopération du téton 22 et de l'ouverture 16, la zone médiane 30 est fléchie à 180° et cette flexion provoque la déformation, - avec mise sous contrainte par compression partielle et de manière par¬ faitement directionnelle -, des zones en partie sphériques 35 et 36. Dans la condition de fermeture,' en laquelle la coiffe 13 est maintenue sur la partie 10 par coopération de formes conjuguées, le plan limitant les bords libres des parties sphériques 35 et 36 forme un angle de sensiblement 90° avec le plan de moulage initial, de sorte que les moyens de char¬ nière forment alors une structure close qui contribue à la bonne étanchéité d'ensemble.When, from the condition shown in Figures 1 and 2, the cap 13 is caused to pivot around the hinge 14 by actuation in the direction of the arrow f_ until the container T is closed by cooperation of the stud 22 and of the opening 16, the median zone 30 is bent by 180 ° and this bending causes the deformation, - under stress by partial compression and in a perfectly directional manner - of the partially spherical zones 35 and 36. In the closed condition, ' in which the cap 13 is held on the part 10 by cooperation of conjugated shapes, the plane limiting the free edges of the spherical parts 35 and 36 forms an angle of substantially 90 ° with the initial molding plane, so that the hinge means then form a closed structure which contributes to the good overall tightness.
Lorsque, pour avoir accès au contenu du récipient T, on écarte la coiffe 13 de la partie 10 solidaire du récipient, la contrainte de compression des zones 35 et 36 en partie sphériques de la charnière 14 est relâchée et leur libération entraîne, par élasticité, l'effet de ressort recherché pour l'ouverture du dispositif.When, in order to gain access to the content of the container T, the cap 13 is removed from the part 10 integral with the container, the compressive stress of the zones 35 and 36 of the spherical part of the hinge 14 is released and their release leads, by elasticity, the desired spring effect for opening the device.
Celui-ci peut être réalisé avec une charnière-film de faible épaisseur, de l'ordre de 3/10 mm, tout en obtenant la facilité requise d'actionnement par la présence des zones en partie sphériques dont le rôle est quelque peu analogue à celui de rotules. This can be achieved with a thin film hinge, of the order of 3/10 mm, while obtaining the required ease of actuation by the presence of partly spherical zones whose role is somewhat analogous to that of ball joints.
