The cap has a cover articulation device (3) that articulates a cover (2) on a base (1) between open and closed positions, where the cap is made by molding in closed position. A connection band (4) is connected to a ring that is supported on the base. A clamp provides a dead point to the device (3), when the cover is spaced from the base by pivoting during the opening of the cap. The clamp provides a spring effect to the device (3) when the cover exceeds the dead point while a user handles the cap. The cover is positioned in open or closed position, due to the spring effect. An independent claim is also included for an assembly comprising a container and a plastic cap.

Description

L'invention concerne un bouchon en matière plastique et un ensemble comprenant un bouchon et un récipient.The invention relates to a plastic plug and an assembly comprising a plug and a container.

Le bouchon selon l'invention est du type comportant une base à fixer au voisinage du goulot de la bouteille et une coiffe montée articulée entre une position de fermeture du récipient et une position d'ouverture.The plug according to the invention is of the type comprising a base to be fixed in the vicinity of the neck of the bottle and a cap mounted articulated between a closed position of the container and an open position.

Elle vise plus particulièrement le dispositif d'articulation du bouchon situé entre sa base et sa coiffe.It is more particularly the device for articulation of the plug located between its base and its cap.

Le document FR-A- 2 350 272 décrit un bouchon verseur dont l'ouverture résiste aux enfants, qui comprend une structure à genouillère servant à tenir le couvercle en position d'ouverture ou de fermeture et facilitant l'utilisation du bouchon comme bouchon résistant aux enfants.The document FR-A-2,350,272 discloses a child-resistant pouring cap that includes a toggle structure for holding the lid in the open or closed position and facilitating the use of the cap as a child resistant cap.

Le document US- 5 400 912 décrit un bouchon pouvant être moulé fermé, ayant une coiffe plate et un dispositif d'articulation attenant à la face d'extrémité libre de la coiffe. Ce dispositif d'articulation comporte d'une part deux zones plates formant charnières coaxiales mais écartées l'une de l'autre, et d'autre part une charnière en U qui est située entre les deux zones plates formant charnières. Cette charnière en U est située vers l'intérieur du bouchon.The document US 5 400 912 discloses a closed moldable plug having a flat cap and a hinge device adjoining the free end face of the cap. This hinge device comprises on the one hand two flat zones forming coaxial hinges but spaced apart from each other, and on the other hand a U-shaped hinge which is located between the two flat hinge zones. This U-shaped hinge is located towards the inside of the cap.

Le document EP-0 309 396 décrit un bouchon présentant une base à fixer sur le col d'un récipient, la base étant reliée par une charnière à une coiffe de fermeture du récipient. Au niveau du plan de jonction entre la base et la coiffe, ces dernières présentent des diamètres différents, de sorte qu'il existe un espace vide périphérique au col du récipient, entre la base et la coiffe. La charnière est située vers l'intérieur du bouchon de sorte que quand la coiffe est en position fermée, la charnière n'est pas visible.The document EP-0 309 396 discloses a plug having a base to be fixed on the neck of a container, the base being connected by a hinge to a closure cap of the container. At the junction plane between the base and the cap, the latter have different diameters, so that there is a peripheral empty space at the neck of the container, between the base and the cap. The hinge is located towards the inside of the plug so that when the cap is in the closed position, the hinge is not visible.

Le document DE 23 55 818 décrit un bouchon d'un pièce ayant une base et une coiffe articulée par un dispositif d'articulation, lequel est composée d'une paire de charnières pivotant au niveau de leur zone amincie médiane, et d'un étrier central situé entre les deux charnières afin de positionner le bouchon dans une position ouverte ou fermé. Ce bouchon est moulé en position ouverte.The document DE 23 55 818 discloses a one-piece plug having a base and a cap hinged by a hinge device, which is composed of a pair of pivoting hinges at their median thinned area, and a central yoke located between the two hinges to position the plug in an open or closed position. This cap is molded in the open position.

Le document WO-2004/007313 décrit un dispositif de fermeture comportant un capot articulé à une bague par une lanière, et la bague est conçue pour se fixer sur une base vissée sur le col d'un récipient. Les zones sensibles du bouchon sont réalisées de telle manière qu'elles sont susceptibles d'être en contact d'un liquide lorsque le dispositif est plongé dans le liquide ou lorsque le liquide est pulvérisé sur le dispositif, et aptes à être ensuite traitée afin d'éliminer le liquide, de sorte à permettre l'aseptisation du bouchon.The document WO-2004/007313 discloses a closure device having a cover hinged to a ring by a strap, and the ring is adapted to attach to a base screwed onto the neck of a container. The sensitive areas of the plug are made in such a way that they are likely to be in contact with a liquid when the device is immersed in the liquid or when the liquid is sprayed on the device, and able to be subsequently treated in order to eliminate the liquid, so as to allow the cap to be sanitized.

Les dispositifs précités présentent certains inconvénients. En effet, et par exemple, les bouchons moulés ouverts sont plus chers de fabrication, à cause des dimensions plus importantes des moules et à cause des machines qu'il faut impérativement prévoir pour refermer les bouchons après conditionnement des produits dans les récipients.The aforementioned devices have certain disadvantages. Indeed, and for example, the open molded plugs are more expensive manufacturing, because of the larger dimensions of the molds and because of the machines that must imperatively provide to close the caps after packaging of the products in the containers.

L'invention a pour objectif de réaliser un bouchon en matière plastique du type comprenant une base, une coiffe de fermeture, du type de ceux qui permettent à un utilisateur de « boire directement au goulot », c'est-à-dire de porter à leur bouche le bouchon afin de boire le contenu du récipient.The invention aims to provide a plastic plug of the type comprising a base, a closure cap, of the type that allow a user to "drink directly to the neck", that is to say to wear at their mouth the cap to drink the contents of the container.

Un autre objectif de l'invention est de réaliser un bouchon confortable pour un utilisateur, autrement dit un bouchon qui soit réalisé de telle manière qu'il ne gêne pas l'utilisateur lorsqu'il le porte à sa bouche.Another object of the invention is to provide a comfortable plug for a user, that is to say a plug that is made in such a way that it does not interfere with the user when he wears it to his mouth.

Un autre objectif de l'invention est de réaliser un bouchon apte à subir des traitements d'aseptisation.Another object of the invention is to provide a plug capable of undergoing sanitizing treatments.

Un autre objectif de l'invention est de réaliser un bouchon qui comporte un dispositif d'articulation de la coiffe sur la base, le dispositif d'articulation étant tel qu'il présente un point mort lorsque la coiffe est écartée de la base par pivotement lors de l'ouverture du bouchon et un effet ressort lorsque la coiffe a dépassé le dit point mort, de manière telle que lorsque l'utilisateur ouvre le bouchon en écartant par pivotement la coiffe de la base, la coiffe dépasse rapidement le point mort, puis grâce à l'effet ressort se positionne d'elle-même écartée de la base.Another object of the invention is to provide a plug which comprises a device for articulating the cap on the base, the hinge device being such that it has a dead point when the cap is pivoted away from the base. when opening the cap and a spring effect when the cap has exceeded the said dead point, so that when the user opens the cap by pivotally separating the cap of the base, the cap quickly exceeds the dead point, then thanks to the spring effect is positioned itself away from the base.

L'invention répond à tous ces objectifs. Elle concerne un bouchon selon la revendication 1.The invention meets all these objectives. It relates to a stopper according to claim 1.

Cette disposition assure une meilleure étanchéité que celle qui est assurée par le dispositif décrit dans le document EP-0 309 396 présenté ci avant.This arrangement provides a better seal than that provided by the device described in the document EP-0 309 396 presented above.

Selon d'autres caractéristiques du bouchon, la zone transversale amincie déformable de la bande de liaison est linéaire ou étroite. La bande de liaison présente une forme symétrique par rapport à la zone transversale amincie déformable, à savoir une première et une seconde parties extrêmes massives et de grande épaisseur et une zone transversale amincie déformable de plus faible épaisseur. La première et / ou la seconde partie extrême de la bande de liaison est incurvée à concavité tournée vers l'extérieur du bouchon, la face de la bande de liaison qui est opposée à l'étrier étant, dans la configuration correspondant au bouchon ouvert, plane.According to other features of the plug, the deformable thinned transverse zone of the connecting strip is linear or narrow. The connecting strip has a symmetrical shape with respect to the deformable thinned transverse zone, namely a first and a second extreme thick and massive end portions and a deformable thinned transverse zone of smaller thickness. The first and / or the second end portion of the connecting strip is curved concavity facing outwardly of the cap, the face of the connecting strip which is opposite the stirrup being, in the configuration corresponding to the open cap, plane.

L'épaisseur des première et seconde parties extrêmes massives de la bande de liaison peut être de trois à six fois l'épaisseur de la zone transversale amincie déformable. La longueur de la bande de liaison est de quatre à six fois l'épaisseur de ses première et seconde parties extrêmes massives.The thickness of the first and second massive end portions of the bonding strip can be three to six times the thickness of the cross-sectional area thinned deformable. The length of the connecting strip is four to six times the thickness of its first and second massive end portions.

Dans une réalisation, la bande de liaison a une longueur de 8 mm, la zone transversale amincie déformable une épaisseur de 0,3 mm et les première et seconde parties extrêmes massives une épaisseur moyenne de 1 mm.In one embodiment, the connecting strip has a length of 8 mm, the deformable thinned transverse zone has a thickness of 0.3 mm and the first and second extreme solid parts have an average thickness of 1 mm.

La zone transversale amincie déformable de la bande de liaison a une largeur de grandeur de son épaisseur. La bande de liaison et l'étrier ont une même largeur transversale de 1,5 mm. Ils sont réalisés de telle manière que, quand la coiffe est en position fermée, il existe une ouverture de passage pour un liquide aseptique entre la bande et la coiffe.The deformable thinned transverse zone of the bonding strip has a width of magnitude of its thickness. The connecting strip and the stirrup have the same transverse width of 1.5 mm. They are made in such a way that, when the cap is in the closed position, there is a passage opening for an aseptic liquid between the band and the cap.

Avec la disposition décrite, la bande de liaison est apte à se trouver dans deux configurations extrêmes, à savoir d'une part une configuration correspondant au bouchon fermé, dans laquelle elle est repliée sur elle même, les première et seconde parties extrêmes massives étant alors situées au droit l'une de l'autre en direction axiale du bouchon, et d'autre part une configuration correspondant au bouchon ouvert, dans laquelle elle est plane, la course de pivotement de la coiffe autour de l'axe de pivotement étant de 180°. L'étrier a une forme courbe en U dans lequel se loge la bande de liaison lorsque celle-ci est dans sa configuration correspondant au bouchon fermé.With the arrangement described, the connecting strip is able to be in two extreme configurations, namely on the one hand a configuration corresponding to the closed cap, in which it is folded on itself, the first and second massive outer parts then being located axially opposite the plug, and on the other hand a configuration corresponding to the open plug, in which it is flat, the pivoting stroke of the cap about the pivot axis being 180 °. The stirrup has a U-shaped curved shape in which the connection strip is housed when it is in its configuration corresponding to the closed plug.

Plus précisément, l'étrier a une forme de U dont les branches sont légèrement évasées. L'étrier a une forme de U d'épaisseur constante, à l'exception des parties extrêmes libres des branches qui sont amincies qui forment les première et seconde parties extrêmes amincies déformables de l'étrier définissant le premier et le second axe d'articulation transversal.Specifically, the stirrup has a U-shape whose branches are slightly flared. The stirrup has a constant thickness U-shape, with the exception of the free end portions of the branches which are thinned which form the first and second deformable thinned end portions of the stirrup defining the first and the second articulation axis transverse.

Dans une réalisation, l'étrier a une épaisseur de l'ordre de grandeur de l'épaisseur de la bande de liaison entre ses première et seconde parties extrêmes et la zone transversale amincie déformable définissant l'axe de pivotement de la coiffe par rapport à la base. L'épaisseur des parties extrêmes libres des branches de l'étrier est de grandeur de l'épaisseur de la zone transversale amincie déformable de la bande de liaison. La longueur des parties extrêmes libres des branches de l'étrier est de grandeur de leur épaisseur.In one embodiment, the stirrup has a thickness of the order of magnitude of the thickness of the connecting strip between its first and second end portions and the deformable thinned transverse zone defining the pivot axis of the cap with respect to the base. The thickness of the free end portions of the stirrup legs is of magnitude of the thickness of the thinned cross-section deformable of the connecting band. The length of the free end parts of the arms of the stirrup is of size of their thickness.

Dans une réalisation, l'étrier a une longueur de 5 mm et une épaisseur de 1 mm, les parties extrêmes libres des branches ayant une épaisseur de 0,3 mm.In one embodiment, the stirrup has a length of 5 mm and a thickness of 1 mm, the free end parts of the branches having a thickness of 0.3 mm.

Dans la réalisation envisagée, la bande de liaison et l'étrier sont réalisés en polypropylène.In the embodiment envisaged, the connecting strip and the stirrup are made of polypropylene.

Dans une variante de réalisation, la bande de liaison et l'étrier pourraient être réalisés dans un matériau plastique présentant des propriétés physiques similaires à celles du polypropylène.In an alternative embodiment, the connecting strip and the stirrup could be made of a plastic material having physical properties similar to those of polypropylene.

Plus particulièrement, la bande de liaison et l'étrier sont réalisés de façon monobloc au moins avec les parties de la base et de la coiffe du bouchon qui sont attenantes au dispositif d'articulation. Plus précisément encore, la bande de liaison, l'étrier, la base et la coiffe sont réalisés de façon monobloc à l'état fermé du bouchon.More particularly, the connecting strip and the stirrup are made integrally at least with the parts of the base and the plug cap which are adjacent to the articulation device. More specifically, the connecting strip, the stirrup, the base and the cap are made integrally in the closed state of the cap.

Les dispositions décrites sont tout particulièrement adaptées au cas où la première partie extrême de la bande de liaison est attenante à la bague qui est montée rigidement sur une partie de la base du bouchon faisant corps.The arrangements described are particularly suitable in the case where the first end portion of the connecting strip is adjacent to the ring which is rigidly mounted on a portion of the base of the plug body.

Dans ce cas, le corps peut comporter une partie de fixation sur le col d'un récipient, de forme cylindrique, pourvue de moyens d'accrochages susceptibles de coopérer avec des moyens d'accrochage complémentaires du récipient, et une partie formant goulot, la bague étant montée dans une rainure située entre la partie de fixation et la partie formant goulot. La partie du corps formant goulot présente une forme de tronc de cône ou de pseudo-tronc de cône. Le corps est pourvu d'un filetage de fixation au col du récipient et d'une bague d'inviolabilité à ponts ou équivalent frangibles.In this case, the body may comprise a fixing portion on the neck of a container, of cylindrical shape, provided with hooking means capable of cooperating with complementary fastening means of the container, and a neck portion, the ring being mounted in a groove between the fixing portion and the neck portion. The neck portion of the body has a form of truncated cone or pseudo-truncated cone. The body is provided with a thread for attachment to the neck of the container and a tamper-evident ring with bridges or frangible equivalent.

D'autre part, la bague sur laquelle est fixée la bande de liaison comporte au moins un pont frangible ou équivalent de liaison avec la coiffe. Ce pont frangible est situé diamétralement à l'opposé du dispositif d'articulation.On the other hand, the ring on which is fixed the connecting strip comprises at least one frangible bridge or equivalent connection with the cap. This frangible bridge is located diametrically opposite the hinge device.

En outre, la coiffe comporte diamétralement à l'opposé du dispositif d'articulation une forme ergonomique pour le doigt, notamment le pouce, de l'utilisateur en vue d'ouvrir le bouchon. Cette forme ergonomique comporte une face latérale tronconique incurvée à concavité tournée vers l'extérieur du bouchon et une partie en saillie en direction transversale diamétralement opposée au dispositif d'articulation, sur la face transversale d'extrémité opposée à la bague.In addition, the cap has diametrically opposite the hinge device ergonomic shape for the finger, including the thumb, the user to open the cap. This ergonomic shape has a concave frustoconical lateral face concavity facing outwardly of the plug and a projecting portion in the transverse direction diametrically opposite the articulation device, on the transverse end face opposite the ring.

Avec la disposition constructive décrite, le point mort est atteint après une course de 90°.With the described constructive arrangement, the dead point is reached after a stroke of 90 °.

Suivant un mode de réalisation avantageux, la coiffe présente un diamètre voisin du diamètre d'une partie de la base sur laquelle elle est placée en position de fermeture du bouchon, pour assurer une fermeture étanche du bouchon par serrage radial.According to an advantageous embodiment, the cap has a diameter close to the diameter of a portion of the base on which it is placed in the closed position of the plug, to ensure sealing of the plug by radial clamping.

Au regard de l'art antérieur, le bouchon selon l'invention présente les avantages suivants :

  • Du fait que le bouchon est conçu pour être moulé fermé, il assure une meilleure étanchéité au voisinage de la partie du corps formant goulot que les bouchons qui sont moulés ouvert. En effet, les bouchons qui sont réalisés par moulage en position ouverte ont tendance se fermer moins bien que ceux qui sont réalisés par moulage en position fermée.
  • Également, le moulage du bouchon en position fermée permet d'équiper le bouchon d'un témoin d'inviolabilité, tel qu'une bague d'inviolabilité reliée à la coiffe par des ponts frangibles. Suivant ce mode de réalisation, le dispositif d'articulation relie la bague d'inviolabilité et la coiffe, et l'ensemble est rapporté sur le corps de la base venant se visser sur le goulot d'un récipient, tel qu'une bouteille par exemple.
  • Le moulage en position fermé réduit les coûts de production du bouchon. En effet, le moule nécessaire à sa réalisation est de dimension plus petite que le moule nécessaire à la réalisation d'un bouchon en position ouverte. D'autre part, il est inutile de prévoir une machine de fermeture du bouchon.
  • La réalisation du dispositif d'articulation permet l'aseptisation du bouchon.
  • Du fait de la présence de la bande de liaison et de l'étrier, le dispositif d'articulation est plus résistant que les dispositifs de l'art antérieur, ces derniers ayant tendance à se casser lorsqu'une force de torsion leur est appliquée.
  • Du fait que le dispositif d'articulation se trouve à l'extérieur du bouchon, l'utilisateur n'est pas gêné par ce dispositif lorsqu'il porte le bouchon à sa bouche.
In view of the prior art, the plug according to the invention has the following advantages:
  • Because the plug is designed to be molded closed, it provides a better seal near the neck portion of the neck than the plugs that are molded open. Indeed, the plugs which are made by molding in the open position tend to close less well than those which are made by molding in the closed position.
  • Also, the molding of the cap in the closed position makes it possible to equip the stopper with a tamper-proof indicator, such as a tamper-proof ring connected to the cap by frangible bridges. According to this embodiment, the hinge device connects the tamper-evident ring and the cap, and the assembly is attached to the body of the base which is screwed onto the neck of a container, such as a bottle by example.
  • Molding in the closed position reduces the production costs of the cap. Indeed, the mold required for its realization is of smaller size than the mold necessary for the production of a plug in the open position. On the other hand, it is useless to provide a plug closure machine.
  • The embodiment of the hinge device allows the cap to be sanitized.
  • Due to the presence of the connecting strip and the stirrup, the articulation device is stronger than the devices of the prior art, the latter having a tendency to break when a torsion force is applied thereto.
  • Because the hinge device is outside the cap, the user is not bothered by this device when he wears the cap to his mouth.

Selon un second aspect, l'invention concerne un ensemble comportant un récipient et un bouchon tel qu'il vient d'être décrit.According to a second aspect, the invention relates to an assembly comprising a container and a cap as just described.

D'autres avantages et caractéristiques du bouchon selon l'invention apparaîtront à la lecture de la description qui va suivre, en faisant notamment référence aux figures 1 à 6 parmi lesquelles :

  • Et la figure 6 illustre en vue de coupe d'un dispositif d'articulation selon l'invention.
Other advantages and characteristics of the plug according to the invention will become apparent on reading the following description, with particular reference to the Figures 1 to 6 among :
  • The figure 1 illustrates a plug according to an advantageous embodiment in side view;
  • The figure 2 shows the cap of the figure 1 in side view, the plug cap being shown in the open position;

  • The figure 5 is an enlargement of the articulation device represented in figure 2 ;
  • And the figure 6 illustrates in sectional view of a hinge device according to the invention.

La figure 1 représente un bouchon selon l'invention qui est réalisé en matière plastique, et plus particulièrement en polypropylène.The figure 1 represents a plug according to the invention which is made of plastic material, and more particularly of polypropylene.

Le bouchon comprend une base 1, une coiffe 2 et un dispositif 3 d'articulation de la coiffe 2 sur la base 1 entre une position fermée, illustré sur la figure 1, et une position ouverte illustrée sur la figure 2.The cap comprises a base 1, a cap 2 and a device 3 for articulating the cap 2 on the base 1 between a closed position, illustrated in FIG. figure 1 , and an open position illustrated on the figure 2 .

Le dispositif d'articulation 3 est réalisé monobloc entre la coiffe 2 et une bague 13 rapportée sur et autour de la base 1 .The hinge device 3 is made in one piece between the cap 2 and a ring 13 attached to and around the base 1.

On prévoit de réaliser la coiffe dans un matériau transparent, de manière à laisser apparaître un embout de la base 1 qui est conçu pour être porté à la bouche d'un utilisateur. Cette réalisation permet ainsi à un utilisateur de reconnaître le bouchon.It is intended to make the cap in a transparent material, so as to reveal a tip of the base 1 which is designed to be worn in the mouth of a user. This embodiment thus allows a user to recognize the plug.

Suivant l'invention, et comme le montre plus particulièrement la figure 2, le dispositif d'articulation 3 comporte une bande de liaison 4 et un étrier 5.According to the invention, and as shown more particularly figure 2 , the articulation device 3 comprises a connecting strip 4 and a stirrup 5.

La bande de liaison 4 est reliée d'un côté par sa première partie extrême 41 à la bague 13 et du côté opposé par sa seconde partie extrême 42 à la coiffe 2.The connecting strip 4 is connected on one side by its first end portion 41 to the ring 13 and on the opposite side by its second end portion 42 to the cap 2.

La bande de liaison 4 comporte une zone transversale amincie 43 qui est déformable et qui définit au moins sensiblement un axe de pivotement X (figure 3) de la coiffe 2 par rapport à la base 1 entre une position ouverte de la coiffe et une position fermée.The connecting strip 4 comprises a thinned transverse zone 43 which is deformable and which at least substantially defines a pivot axis X ( figure 3 ) of the cap 2 relative to the base 1 between an open position of the cap and a closed position.

Pour ce faire, la zone transversale amincie 43 de la bande de liaison 4 est réalisée linéaire ou étroite, comme le montre les figures 1, 2, 3, 5 et 6.To do this, the thinned transverse zone 43 of the connecting strip 4 is made linear or narrow, as shown in FIGS. Figures 1, 2 , 3 , 5 and 6 .

La bande de liaison 4 présente une forme sensiblement symétrique par rapport à la zone transversale amincie 43, c'est-à-dire une première partie 44 et une seconde partie 45 qui sont extrêmes, massives et de grande épaisseur (figures 5 et 6), la zone transversale amincie 43 étant de plus faible épaisseur.The connecting strip 4 has a substantially symmetrical shape with respect to the thinned transverse zone 43, that is to say a first part 44 and a second part 45 which are extreme, massive and of great thickness ( figures 5 and 6 ), the thinned transverse zone 43 being of smaller thickness.

Comme l'illustrent plus particulièrement les figures 1, 2 et 3, la première 44 et la seconde 45 partie extrême de la bande de liaison 4 sont incurvées à concavité tournée vers l'extérieur du bouchon, la face de la bande de liaison 4 qui est opposée à l'étrier étant, dans la configuration correspondant au bouchon ouvert (figure 2), sensiblement plane.As illustrated more particularly by Figures 1, 2 and 3 , the first 44 and the second 45 end portions of the connecting strip 4 are concavely curved towards the outside of the cap, the face of the connecting strip 4 which is opposite the stirrup being, in the configuration corresponding to the open cap ( figure 2 ), substantially flat.

L'épaisseur des première 44 et seconde 45 parties extrêmes massives de la bande de liaison 4 est de l'ordre de trois à six fois l'épaisseur de la zone transversale amincie déformable.The thickness of the first 44 and second 45 extreme end portions of the connecting strip 4 is of the order of three to six times the thickness of the deformable thinned transverse zone.

Aussi, la longueur de la bande de liaison 4 est de l'ordre de quatre à six fois l'épaisseur de ses première 44 et seconde 45 parties extrêmes massives.Also, the length of the connecting strip 4 is of the order of four to six times the thickness of its first 44 and second 45 extreme end portions.

Dans le cadre de ce mode de réalisation, la bande de liaison 4 a une longueur de l'ordre de 8 mm, la zone transversale amincie déformable 43 présente une épaisseur de l'ordre de 0,3 mm et les première 44 et seconde 45 parties extrêmes massives une épaisseur moyenne de l'ordre de 1 mm.In the context of this embodiment, the connecting strip 4 has a length of the order of 8 mm, the deformable thinned transverse zone 43 has a thickness of the order of 0.3 mm and the first 44 and second 45 massive extreme parts an average thickness of the order of 1 mm.

La largeur de la zone transversale 43 est sensiblement égale à son épaisseur, soit 0,3 mm.The width of the transverse zone 43 is substantially equal to its thickness, ie 0.3 mm.

L'étrier 5 présente une forme de bande courbe. Dans le cadre de ce mode de réalisation, l'étrier 5 présente une forme de bande conformée en U en position ouverte (figure 5). Il devra toutefois être compris que l'invention n'est pas limitée à la réalisation d'un étrier en forme de U, car l'étrier pourrait présenter toute forme courbe.The stirrup 5 has a curved band shape. In the context of this embodiment, the stirrup 5 has a U-shaped strip shape in the open position ( figure 5 ). It should be understood, however, that the invention is not limited to the production of a U-shaped stirrup, because the stirrup could have any curved shape.

Dans le cadre du mode de réalisation présentement décrit et représenté sur la figure 6, l'étrier est situé par rapport à la bande de liaison 4 à proximité et au droit d'elle en direction axiale du bouchon. L'étrier 5 est réalisé de telle manière qu'il est la partie du bouchon la plus éloignée de la coiffe, de manière à venir entourer l'étrier.In the context of the embodiment currently described and represented on the figure 6 , the stirrup is located relative to the connecting strip 4 in the vicinity and to the right of it in the axial direction of the plug. The stirrup 5 is made in such a way that it is the part of the stopper farthest from the cap, so as to surround the stirrup.

Comme le montrent les figures 1, 2 et 3, l'étrier 5 est localisé à l'extérieur du bouchon.As shown by Figures 1, 2 and 3 , the stirrup 5 is located outside the cap.

Comme représenté sur la figure 6, l'étrier 5 est relié d'un côté à la première partie extrême 41 de la bande de liaison 4 par une première partie extrême amincie 51 qui est déformable autour d'un premier axe d'articulation transversal (figure 1). La partie extrême amincie 51 comporte un créneau 51a sur toute sa largeur. La partie 51 se prolonge sur la branche 53 par une section chanfreinée 53a de raccordement.As shown on the figure 6 the yoke 5 is connected on one side to the first end portion 41 of the connecting strip 4 by a first thinned end portion 51 which is deformable around a first transverse hinge axis ( figure 1 ). The thinned end portion 51 has a slot 51a along its entire width. The portion 51 extends on the branch 53 by a chamfered section 53a connection.

L'étrier 5 est relié du côté opposé à la seconde partie extrême 42 de la bande de liaison 4 par une seconde partie extrême amincie 52 qui est déformable autour d'un second axe d'articulation transversal.The yoke 5 is connected on the opposite side to the second end portion 42 of the connecting strip 4 by a second thinned end portion 52 which is deformable about a second axis of transverse articulation.

La partie amincie 52 se rattache à la section en U de l'étrier par une zone 54 de raccordement à bord intérieur curviligne.The thinned portion 52 is attached to the U-shaped section of the stirrup by a connecting zone 54 with a curvilinear inner edge.

La paroi intérieure de la bague 13 présente dans la zone de raccordement à la bande de liaison, une dépouille 41 a qui se prolonge par un bossage 44a de liaison disposé sur la partie extrême massive 44 de la bande de liaison.The inner wall of the ring 13 has in the area of connection to the connecting strip, a recess 41a which is extended by a boss 44a connecting disposed on the solid end portion 44 of the connecting strip.

La paroi intérieure de la zone de raccordement entre, d'une part, la seconde partie extrême 42 de la bande de liaison et, d'autre part, la seconde partie extrême amincie 52 de l'étrier 5, présente un épaulement intérieur à angle vif 42a. La paroi intérieure de la partie extrême massive 45 présente une courbure 45a qui fait face au bossage 44a en position de fermeture du dispositif d'articulation (figure 6).The inner wall of the connection zone between, on the one hand, the second end portion 42 of the connecting strip and, on the other hand, the second thinned end portion 52 of the stirrup 5, has an angled inner shoulder. lively 42a. The inner wall of the solid end portion 45 has a curvature 45a which faces the boss 44a in the closed position of the articulation device ( figure 6 ).

Conformément à l'invention, l'étrier 5 est conçu de manière à être suffisamment rigide dans son ensemble mais néanmoins déformable, pour conférer au dispositif d'articulation :

  • un point mort lorsque la coiffe est écartée de la base par pivotement lors de l'ouverture du bouchon,
  • et un effet ressort lorsque la coiffe a dépassé ledit point mort.
According to the invention, the stirrup 5 is designed to be sufficiently rigid as a whole but nevertheless deformable, to give the articulation device:
  • a dead point when the cap is pivotally separated from the base when the cap is opened,
  • and a spring effect when the cap has passed said dead point.

De cette manière, lorsque l'utilisateur manoeuvre le bouchon en écartant ou en rapprochant par pivotement la coiffe de la base, la coiffe dépasse rapidement le point mort, puis grâce à l'effet ressort se positionne d'elle-même dans une position d'ouverture ou dans une position de fermeture.In this way, when the user maneuver the cap by separating or by pivotally bringing the cap of the base, the cap quickly exceeds the neutral position, and thanks to the spring effect is positioned itself in a position d opening or in a closed position.

Plus particulièrement, la position de pleine ouverture de la coiffe correspond à une position stable obtenue par tension de l'étrier sous l'action du déploiement de la bande de liaison.More particularly, the fully open position of the cap corresponds to a stable position obtained by tension of the caliper under the action of the deployment of the connecting strip.

En position d'ouverture, l'étrier est sous contrainte et il subit l'effet de tension de la bande de liaison qui forme un arc-boutement entre la coiffe et la base.In the open position, the yoke is under stress and it undergoes the tension effect of the connecting strip which forms an arching between the cap and the base.

Dans le cadre du mode de réalisation illustré sur les figures, la bande de liaison et l'étrier ont une largeur transversale de l'ordre de 1,5 mm.In the context of the embodiment illustrated in the figures, the connecting strip and the stirrup have a transverse width of the order of 1.5 mm.

Pour assurer le passage de la coiffe de sa position fermée illustrée en figure 1 à sa position ouverte illustrée en figure 2, la bande de liaison est conçue pour présenter deux configurations extrêmes, à savoir d'une part une configuration correspondant à la position fermée de la coiffe, et d'autre part une configuration correspondant à la position ouverte de la coiffe.To ensure the passage of the cap from its closed position illustrated in figure 1 at its open position illustrated in figure 2 , the connecting strip is designed to have two extreme configurations, namely on the one hand a configuration corresponding to the closed position of the cap, and on the other hand a configuration corresponding to the open position of the cap.

Quand elle adopte sa configuration fermée, la bande de liaison 4 est repliée sur elle-même. Les première 44 et seconde 45 parties extrêmes massives sont alors situées sensiblement au droit l'une de l'autre en direction axiale du bouchon (figures 1 et 3).When it adopts its closed configuration, the connecting strip 4 is folded back on itself. The first 44 and second 45 massive end portions are then located substantially right of each other in the axial direction of the plug ( figures 1 and 3 ).

Quand elle adopte sa configuration ouverte, la bande de liaison 4 est sensiblement plane, la course de pivotement de la coiffe autour de l'axe de pivotement étant de l'ordre de 180° (voir figure 2).When it adopts its open configuration, the connecting strip 4 is substantially flat, the pivoting stroke of the cap around the pivot axis being of the order of 180 ° (see figure 2 ).

Cette course, ou rotation de 180° est possible grâce à la forme de la bande au voisinage de la zone transversale amincie 43.This stroke, or rotation of 180 ° is possible thanks to the shape of the band in the vicinity of the thinned transverse zone 43.

Comme on peut le voir sur la figure 4, la bande de liaison 4 présente un plat 46 perpendiculaire au plan de jonction entre les deux parties de la bande dans la zone transversale amincie 43.As can be seen on the figure 4 , the connecting strip 4 has a flat 46 perpendicular to the plane of junction between the two parts of the strip in the thinned transverse zone 43.

Les deux parties de la bande de liaison étant montées articulées, libre en rotation autour de l'axe X (figure 3), l'une de ces parties peut réaliser une rotation par rapport à l'axe d'articulation jusqu'à ce que le plat 46 de cette partie vienne en appui contre le plat 46 de l'autre partie. Ce mouvement correspond à un angle de rotation de 180°.The two parts of the connecting strip being hingedly mounted, free to rotate about the X axis ( figure 3 ), one of these parts can rotate relative to the axis of articulation until the plate 46 of this part bears against the plate 46 of the other part. This movement corresponds to an angle of rotation of 180 °.

Comme on peut le voir sur les figures 1 et 3, l'étrier 5 a une forme générale de U dans lequel se loge la bande de liaison 4 lorsque celle-ci est dans sa configuration correspondant au bouchon fermé.As can be seen on the figures 1 and 3 , the stirrup 5 has a general U-shape in which is housed the connecting strip 4 when it is in its configuration corresponding to the closed cap.

Quand la coiffe est en position ouverte, l'étrier 5 a également une forme générale de U. Toutefois, comme on le voit plus particulièrement sur la figure 2, les branches du U sont légèrement évasées.When the cap is in the open position, the stirrup 5 also has a general shape of U. However, as can be seen more particularly on the figure 2 , the branches of the U are slightly flared.

Contrairement on peut le voir notamment sur la figure 2, l'étrier 5 a une forme de U d'épaisseur sensiblement constante, à l'exception des parties extrêmes libres et des branches qui sont amincies qui forment les première 51 et seconde 52 parties extrêmes amincies déformables de l'étrier définissant le premier et le second axe d'articulation transversal.Unlike it can be seen in particular on the figure 2 the yoke 5 has a U-shape of substantially constant thickness, with the exception of the free end portions and branches which are thinned which form the first 51 and second 52 deformable thinned end portions of the yoke defining the first and second the second axis of transverse articulation.

L'étrier 5 présente une épaisseur de l'ordre de grandeur de l'épaisseur de la bande de liaison 4 entre ses première et seconde parties extrêmes 51 et 52, et la zone transversale amincie 43 de la bande de liaison 4 qui définit l'axe de pivotement de la coiffe 2 par rapport à la base 1.The stirrup 5 has a thickness of the order of magnitude of the thickness of the connecting strip 4 between its first and second end portions 51 and 52, and the thinned transverse zone 43 of the connecting strip 4 which defines the pivot axis of the cap 2 relative to the base 1.

Concernant l'épaisseur des parties extrêmes 51 et 52 de l'étrier, elle est de l'ordre de grandeur de l'épaisseur de la zone transversale amincie déformable 43 de la bande de liaison 4.As regards the thickness of the end portions 51 and 52 of the stirrup, it is of the order of magnitude of the thickness of the deformable thinned transverse zone 43 of the connecting strip 4.

La longueur des parties extrêmes 51 et 52 de l'étrier est de l'ordre de grandeur de leur épaisseur.The length of the end portions 51 and 52 of the stirrup is of the order of magnitude of their thickness.

Selon le mode de réalisation illustré sur les figures, l'étrier 5 a une longueur de l'ordre de 5 mm et une épaisseur de l'ordre de 1 mm, et les parties extrêmes libres 51 et 52 présentent une épaisseur de l'ordre de 0,3 mm.According to the embodiment illustrated in the figures, the stirrup 5 has a length of the order of 5 mm and a thickness of about 1 mm, and the free end portions 51 and 52 have a thickness of about 0.3 mm.

La bande de liaison 4 et l'étrier 5 sont réalisés de façon monobloc au moins avec les parties de la base 1 et de la coiffe 2 du bouchon qui sont attenantes au dispositif d'articulation 3.The connecting strip 4 and the stirrup 5 are made in one piece at least with the parts of the base 1 and the cap 2 of the cap which are adjacent to the articulation device 3.

La base 1 comporte un corps 11 venant se fixer sur le col d'une bouteille, le col étant de forme cylindrique.The base 1 comprises a body 11 which is fixed on the neck of a bottle, the neck being of cylindrical shape.

Pour ce faire, le corps 11 est pourvu d'un filetage interne coopérant avec le filetage externe complémentaire réalisé sur le col de la bouteille.To do this, the body 11 is provided with an internal thread cooperating with the complementary external threading formed on the neck of the bottle.

Afin d'assurer au consommateur que le bouchon n'a pas été dévissé, le corps 11 est relié à une bague d'inviolabilité 15 par des ponts frangibles.In order to assure the consumer that the stopper has not been unscrewed, the body 11 is connected to a tamperproof ring 15 by frangible bridges.

Le corps de la base comporte également une partie formant goulot 12.The body of the base also has a neck portion 12.

Cette partie formant goulot 12 présente une forme générale de tronc de cône ou de pseudo-tronc de cône, comme illustré sur la figure 2. Cette forme permet au consommateur de porter le bouchon à sa bouche, et de boire directement le liquide contenu dans la bouteille.This neck portion 12 has the general shape of a truncated cone or pseudo-truncated cone, as illustrated in FIG. figure 2 . This form allows the consumer to carry the cap to his mouth, and drink the liquid directly in the bottle.

La bague 13 qui est rapportée sur et autour de la base 1, est montée dans une rainure 14 ménagée autour du corps, entre la partie de fixation et la partie formant goulot 12.The ring 13 which is attached to and around the base 1, is mounted in a groove 14 formed around the body, between the attachment portion and the neck portion 12.

La première partie extrême 41 de la bande de liaison est attenante à la bague 13.The first end portion 41 of the connecting strip is adjacent to the ring 13.

Dans le cadre de ce mode de réalisation, on prévoit de réaliser la bande de liaison 4, l'étrier 5, la bague 13 et la coiffe 2 de façon monobloc, par moulage et en position fermée de la coiffe.In the context of this embodiment, provision is made to make the connecting strip 4, the stirrup 5, the ring 13 and the cap 2 integrally, by molding and in the closed position of the cap.

La jonction entre l'extrémité de coiffe 2 et la bague 13 définit un plan P de joint en position fermée de la coiffe 2 (figure 1), au niveau duquel la coiffe et la bague sont de diamètres sensiblement égaux de sorte qu'il n'existe aucune fente entre la bague et la coiffe.The junction between the cap end 2 and the ring 13 defines a joint plane P in the closed position of the cap 2 ( figure 1 ), at which the cap and the ring are of substantially equal diameters so that there is no slot between the ring and the cap.

De plus, la bague 13 sur laquelle est fixée la bande de liaison 4 comporte au moins deux ponts frangible 16 de liaison avec la coiffe (figure 3).In addition, the ring 13 on which the connecting strip 4 is fixed comprises at least two frangible bridges 16 of connection with the cap ( figure 3 ).

Comme on peut le voir sur la figure 3, les ponts frangibles 16 sont situés diamétralement à l'opposé du dispositif d'articulation 3.As can be seen on the figure 3 , the frangible bridges 16 are located diametrically opposite the articulation device 3.

La bague 13 est également équipée d'un ergot 17 permettant à l'utilisateur de rompre les ponts frangibles 16, en tirant sur l'ergot, pour ouvrir la coiffe lors d'une première utilisation.The ring 13 is also equipped with a lug 17 allowing the user to break the frangible bridges 16, by pulling on the lug, to open the cap during a first use.

L'étanchéité du bouchon est obtenue notamment par serrage radial de la coiffe sur la base. Pour assurer cette fermeture étanche, la coiffe présente un diamètre voisin du diamètre d'une partie 18 de la base sur laquelle elle est placée en position de fermeture du bouchon.The sealing of the plug is obtained in particular by radial clamping of the cap on the base. To ensure this tight closure, the cap has a diameter next to the diameter of a portion 18 of the base on which it is placed in the closed position of the cap.

La coiffe 2 comporte, diamétralement à l'opposé du dispositif d'articulation, un logement 21 de forme ergonomique pour y poser le pouce, de sorte que l'utilisateur ouvre le bouchon d'une seule main, en exerçant une simple poussée avec son pousse dans le logement 21 de la coiffe.The cap 2 comprises, diametrically opposite the hinge device, a housing 21 of ergonomic shape for laying the thumb, so that the user opens the cap with one hand, exerting a simple push with his grows in the housing 21 of the cap.

Comme on peut le voir sur la figure 3, la forme ergonomique de la coiffe comporte une face latérale tronconique incurvée à concavité tournée vers l'extérieur du bouchon et une partie en saillie en direction transversale diamétralement opposée au dispositif d'articulation, sur la face transversale d'extrémité opposée à la bague 13.As can be seen on the figure 3 , the ergonomic shape of the cap comprises a concave frustoconical lateral face concavity facing outwardly of the plug and a projecting portion in the transverse direction diametrically opposite the articulation device, on the transverse end face opposite to the ring 13 .

Enfin, un moletage est réalisé sur le corps 11 pour faciliter sa préhension quand un utilisateur souhaite dévisser entièrement le bouchon.Finally, a knurling is performed on the body 11 to facilitate its grip when a user wants to completely unscrew the cap.

Les éléments principaux du bouchon selon l'invention ayant été exposés, un mode de fabrication du bouchon va maintenant être décrit.The main elements of the plug according to the invention having been exposed, a method of manufacturing the plug will now be described.

Le bouchon détaillé ci avant est réalisé en deux pièces.The cap detailed above is made in two pieces.

La première pièce consiste en le corps 11 solidaire du goulot 12 et de la bague d'inviolabilité 15, et la seconde pièce consiste en la coiffe 2, le dispositif d'articulation 3 et la bague 13.The first part consists of the body 11 integral with the neck 12 and the tamper-proof ring 15, and the second part consists of the cap 2, the articulation device 3 and the ring 13.

Le corps 11, le goulot 12 et la bague d'inviolabilité 15 sont réalisés en une seule pièce par injection de matière plastique dans un moule. Plus particulièrement, la matière plastique consiste en du polypropylène destiné au conditionnement de produits alimentaires, ou tout autre matériau équivalent du point de vue de ses capacités de déformation.The body 11, the neck 12 and the tamperproof ring 15 are made in one piece by injection of plastic into a mold. More particularly, the plastic consists of polypropylene for the packaging of food products, or any other equivalent material from the point of view of its deformation capabilities.

La coiffe 2, la bague 13 et le dispositif d'articulation 3 sont également réalisés en une seule pièce par injection de matière plastique dans un moule, de sorte que la coiffe 2 se trouve en position fermée, reliée à la bague 13 par les ponts frangibles 16. La matière plastique utilisée pour réaliser cette seconde pièce est également le polypropylène destiné au conditionnement alimentaire.The cap 2, the ring 13 and the hinge device 3 are also made in one piece by injecting plastic into a mold, so that the cap 2 is in the closed position, connected to the ring 13 by the bridges. breakable 16. The plastic material used to make this second part is also polypropylene for food packaging.

La première pièce est insérée à force autour du col de la bouteille, de sorte que les ponts frangibles reliant la bague d'inviolabilité 15 au corps 11 ne soient pas rompus avant une première utilisation.The first piece is inserted by force around the neck of the bottle, so that the frangible bridges connecting the tamperproof ring 15 to the body 11 are not broken before a first use.

La seconde pièce est insérée à force autour du goulot 12, en introduisant la bague 13 dans la rainure 14, de manière à ce que les ponts frangibles 16 ne soient pas rompus avant une première utilisation.The second piece is inserted by force around the neck 12, by introducing the ring 13 into the groove 14, so that the frangible bridges 16 are not broken before a first use.

Le bouchon est utilisé comme suit :The cap is used as follows:

Pour une première ouverture de la coiffe, l'utilisateur tire sur l'ergot 17 pour rompre les ponts frangibles 16, de manière à libérer la coiffe 2.For a first opening of the cap, the user pulls on the lug 17 to break the frangible bridges 16, so as to release the cap 2.

Il place son pouce dans le logement 21 et exerce une pression suffisamment forte pour que la course de pivotement de la coiffe atteigne le point mort du bouchon, c'est-à-dire l'angle au-delà duquel la coiffe s'ouvre dans une position maximale par rappel élastique exercé par l'étrier tendant à reprendre sa forme originelle.He places his thumb in the housing 21 and exerts a pressure strong enough that the pivoting stroke of the cap reaches the dead point of the plug, that is to say the angle beyond which the cap opens in a maximum position by elastic return exerted by the stirrup tending to resume its original form.

Dans le cadre de ce mode de réalisation, le point mort est atteint après une course de pivotement de l'ordre de 90°autour de l'axe X représenté en figure 3.In the context of this embodiment, the neutral point is reached after a pivoting stroke of the order of 90 ° around the X axis represented in FIG. figure 3 .

Si la course de pivotement n'atteint pas les 90°, la coiffe est automatiquement rappelée dans sa position fermée par rappel élastique de l'étrier tendant à reprendre sa forme originelle.If the pivoting stroke does not reach 90 °, the cap is automatically recalled in its closed position by elastic return of the stirrup tending to resume its original form.

Quand la coiffe se trouve en position ouverte, elle ne gêne pas l'utilisateur portant le goulot 12 à sa bouche du fait de l'angle de 180° existant entre la coiffe 2 et la bague 13.When the cap is in the open position, it does not interfere with the user carrying the neck 12 to his mouth because of the 180 ° angle between the cap 2 and the ring 13.

Il en va de même pour la charnière qui ne gêne pas non plus l'utilisateur quand il porte le goulot 12 à sa bouche.It is the same for the hinge that does not interfere with the user when he wears the neck 12 to his mouth.
