Description

Domaine techniqueTechnical area

L'invention se rapporte à un ensemble comprenant un récipient et un dispositif de bouchage qui est équipé d'un bouchon et permet de garder ledit bouchon attaché au col du récipient, ce qui évite de perdre le bouchon dans la nature.The invention relates to an assembly comprising a container and a capping device which is equipped with a cap and makes it possible to keep said cap attached to the neck of the container, which avoids losing the cap in nature.

Arrière-plan technologiqueTechnology background

Dans l'état de la technique, il est connu des dispositifs de bouchage permettant de garder un bouchon attaché à un col du récipient. Un tel dispositif de bouchage est, par exemple, décrit dans le document EP1406820 ou US2018086510 .In the state of the art, capping devices are known for keeping a cap attached to a neck of the container. Such a capping device is, for example, described in the document EP1406820 Or US2018086510 .

Le dispositif de bouchage comporte une bague qui est destinée à être retenue sur le col du récipient, un bouchon qui est destiné à recouvrir l'orifice du récipient de manière à l'obturer, deux lamelles élastiques liant le bouchon à la bague inférieure et un dispositif de blocage agencé pour bloquer le bouchon dans une position basculée ouverte.The capping device comprises a ring which is intended to be retained on the neck of the container, a cap which is intended to cover the orifice of the container so as to close it, two elastic strips connecting the cap to the lower ring and a blocking device arranged to block the cap in an open tilted position.

Un tel dispositif de bouchage n'est pas pleinement satisfaisant. En particulier, ce bouchon est destiné à se clipser sur le col du récipient et ne peut être adapté à d'autres types de col. En outre, le mouvement du bouchon entre la position de fermeture et la position basculée ouverte est un simple mouvement de pivotement, ce qui limite la hauteur du bouchon et/ou du col susceptible d'être utilisé. Ceci limite les applications dudit dispositif de bouchage. En particulier, il ne convient pas pour les récipients destinés à recevoir des boissons gazeuses car la pression régnant à l'intérieur de tels récipients conduirait à des ouvertures indésirées du bouchon.Such a closure device is not fully satisfactory. In particular, this cap is intended to clip onto the neck of the container and cannot be adapted to other types of neck. In addition, the movement of the cap between the closed position and the tilted open position is a simple pivoting movement, which limits the height of the cap and/or neck that can be used. This limits the applications of said capping device. In particular, it is not suitable for containers intended to receive carbonated drinks because the pressure prevailing inside such containers would lead to unwanted openings of the cap.

De plus, le dispositif de blocage n'est pas adapté à tous les types de bouchon et n'assure pas une fiabilité suffisante pour maintenir la position basculée ouverte sur des bouchons vissés car exemple.In addition, the blocking device is not suitable for all types of caps and does not provide sufficient reliability to maintain the tilted open position on screwed caps, for example.

The invention provides a set comprising:
  • a container equipped with a neck, the neck comprising a distribution orifice, a helical thread, rotating around an axis
  • a capping device comprising:
    • a lower ring fixed axially to the neck and movable in rotation on the neck around said axis below the hanging collar so as to axially retain the lower ring on the neck of the container and a second sector, the first sector and the second sector of the lower ring being articulated to one another so that the second sector pivots relative to the first sector between a lowered position in which the second sector is arranged below the attachment flange and a raised position in which the second sector is arranged at least partly above the flange hanging,
    • a cap comprising an upper wall and an external peripheral skirt, the external peripheral skirt having a helical thread intended to cooperate with the helical thread of the neck so as to allow the movement of the cap between a closed position and a released position in which the helical thread of the cap is no longer engaged with the helical thread of the neck;

      • a heel which projects axially, from the external peripheral skirt, between the two lamellae of the articulation device and which includes a cleat which projects radially outwards; And
      • a projecting portion which projects axially from the second sector of the lower ring between the two lamellae of the articulation device;
      • the tab and the projecting portion being configured such that, when the cap is in the open tilted position and the second section of the lower ring is in the lowered position, the projecting portion is clamped between the tab and the flange of hooking.

Grâce à un tel agencement, le dispositif de blocage garantit un blocage robuste, avec un angle important, du bouchon dans sa position basculée ouverte. En outre, par rapport à un dispositif de blocage qui comporterait un taquet qui serait configuré pour venir contre le col du récipient, l'agencement proposé permet de limiter la dimension radiale du taquet. Ceci est particulièrement avantageux dans la mesure où un taquet ayant une dimension radiale trop importante est susceptible de nuire à la fiabilité et aux rendements des opérations d'embouteillage au cours desquelles les dispositifs de bouchage sont notamment transportés sur des convoyeurs avant d'être mis en place sur les récipients.Thanks to such an arrangement, the blocking device guarantees robust blocking, with a significant angle, of the cap in its tilted open position. Furthermore, compared to a blocking device which would include a tab which would be configured to come against the neck of the container, the proposed arrangement makes it possible to limit the radial dimension of the tab. This is particularly advantageous insofar as a stopper having too large a radial dimension is likely to harm the reliability and yield of bottling operations during which the capping devices are notably transported on conveyors before being put into place. place on the containers.

Selon d'autres modes de réalisation avantageux, un tel ensemble peut présenter une ou plusieurs des caractéristiques suivantes.According to other advantageous embodiments, such an assembly may have one or more of the following characteristics.

Selon un mode de réalisation, le taquet et la portion en saillie sont configurés de telle sorte que, lorsque le bouchon est en position basculée ouverte et la deuxième section de la bague inférieure est dans la position abaissée, le taquet et la portion en saillie sont en contact l'un contre l'autre dans une zone située dans le plan de la collerette d'accrochage.According to one embodiment, the tab and the projecting portion are configured such that, when the cap is in the open tilted position and the second section of the lower ring is in the lowered position, the tab and the projecting portion are in contact with each other in an area located in the plane of the attachment collar.

Selon un mode de réalisation, e1 > L - e2 avec :

  • L : la longueur des lamelles dans un état initial dans lequel le bouchon dans la position de fermeture ;
  • e1 : une distance radiale entre une zone de contact du taquet destinée à venir en contact avec la portion en saillie lorsque le bouchon est en position basculée ouverte et une intersection entre une droite passant par des extrémités supérieures des lamelles et un plan de symétrie des lamelles l'une par rapport à l'autre ; et
  • e2 : une distance radiale entre une zone de contact de la portion en saillie destinée à venir en contact avec le taquet lorsque le bouchon est en position basculée ouverte et une intersection entre une droite passant par des extrémités inférieure des lamelles et le plan de symétrie P.
According to one embodiment, e1 > L - e2 with:
  • L: the length of the slats in an initial state in which the cap is in the closed position;
  • e1: a radial distance between a contact zone of the cleat intended to come into contact with the projecting portion when the cap is in the open tilted position and an intersection between a straight line passing through the upper ends of the slats and a plane of symmetry of the slats one in relation to the other; And
  • e2: a radial distance between a contact zone of the projecting portion intended to come into contact with the stopper when the cap is in the open tilted position and an intersection between a straight line passing through the lower ends of the strips and the plane of symmetry P .

Selon un mode de réalisation, e1 > L - e2 + e3 +e4 avec :

  • e3 : une jeu radial entre la bague inférieure et le col selon une direction radiale à l'axe X et inscrite dans le plan de symétrie P ; et
  • e4 : un jeu radial entre la portion en saillie et la collerette d'accrochage.
According to one embodiment, e1 > L - e2 + e3 +e4 with:
  • e3: a radial clearance between the lower ring and the neck in a direction radial to the axis X and inscribed in the plane of symmetry P; And
  • e4: a radial clearance between the projecting portion and the attachment collar.

Selon un mode de réalisation, e1 = L - e2 + e3 + e4+ Δ avec Δ compris entre 0,05 et 2 mm.According to one embodiment, e1 = L - e2 + e3 + e4+ Δ with Δ between 0.05 and 2 mm.

Selon un mode de réalisation, la portion en saillie fait saillie au-delà d'une limite inférieure de la jupe périphérique externe.According to one embodiment, the projecting portion projects beyond a lower limit of the external peripheral skirt.

Selon un mode de réalisation, le premier secteur de la bague inférieure comporte une zone avant qui est diamétralement opposée au deuxième secteur et deux zones d'accrochage qui sont chacune disposées entre la zone avant du premier secteur et le deuxième secteur, les éléments d'accrochage étant uniquement disposés dans les deux zones d'accrochage de sorte à permettre un mouvement radial de la bague inférieure apte à faciliter le passage d'une partie du deuxième secteur de part et d'autre de la collerette d'accrochage lors du mouvement du deuxième secteur entre la position abaissée et la position libérée. Ainsi, les efforts de traction à exercer sur la bague inférieure pour permettre au deuxième secteur de se déplacer entre la position abaissée et la position relevée sont moindres, ce qui permet de faciliter l'utilisation du dispositif de bouchage.According to one embodiment, the first sector of the lower ring comprises a front zone which is diametrically opposite to the second sector and two attachment zones which are each arranged between the front zone of the first sector and the second sector, the elements of hooking being only arranged in the two hooking zones so as to allow radial movement of the ring lower capable of facilitating the passage of a part of the second sector on either side of the attachment collar during the movement of the second sector between the lowered position and the released position. Thus, the tensile forces to be exerted on the lower ring to allow the second sector to move between the lowered position and the raised position are less, which makes it easier to use the capping device.

Selon un mode de réalisation, le deuxième secteur est dépourvu d'éléments d'accrochage.According to one embodiment, the second sector is devoid of hooking elements.

Selon un mode de réalisation, la zone avant du premier secteur est dépourvue d'éléments d'accrochage.According to one embodiment, the front zone of the first sector is devoid of hooking elements.

Selon un mode de réalisation, les éléments d'accrochage sont des protubérances qui font saillie radialement vers l'intérieur.According to one embodiment, the hooking elements are protuberances which project radially inwards.

Selon un mode de réalisation, le deuxième secteur s'étend sur une plage angulaire comprise entre 90 et 180°.According to one embodiment, the second sector extends over an angular range of between 90 and 180°.

Selon un mode de réalisation, la zone avant du premier secteur s'étend sur une plage angulaire comprise entre 40 et 150°.According to one embodiment, the front zone of the first sector extends over an angular range of between 40 and 150°.

Selon un mode de réalisation, chacune des deux zones d'accrochage s'étend sur une plage angulaire comprise entre 10 et 90°.According to one embodiment, each of the two attachment zones extends over an angular range of between 10 and 90°.

Selon un mode de réalisation, le premier secteur et le deuxième secteur sont séparés l'un de l'autre par deux zones amincies dans lesquelles la bague inférieure présente localement une diminution d'épaisseur radiale de manière à permettre l'articulation du deuxième secteur par rapport au premier secteur.According to one embodiment, the first sector and the second sector are separated from each other by two thinned zones in which the lower ring locally has a reduction in radial thickness so as to allow the articulation of the second sector by in relation to the first sector.

Selon un autre mode de réalisation, la bague inférieure a une épaisseur suffisamment faible pour permettre le pivotement du deuxième secteur par rapport au premier secteur sans pour autant que le premier secteur et le deuxième secteur soient séparés l'un de l'autre par deux zones amincies.According to another embodiment, the lower ring has a sufficiently small thickness to allow the second sector to pivot relative to the first sector without the first sector and the second sector being separated from each other by two zones. thinned.

Selon un mode de réalisation, la jupe périphérique externe comporte une portion échancrée et les lamelles élastiques rejoignent ladite jupe périphérique externe dans ladite portion échancrée. Un tel agencement permet de ménager des lamelles élastiques de longueur suffisante tout en limitant les dimensions des interstices, ménagés entre le bouchon et la bague inférieure, et susceptibles d'autoriser le passage de poussières.According to one embodiment, the external peripheral skirt comprises a notched portion and the elastic strips join said external peripheral skirt in said notched portion. Such an arrangement makes it possible to provide elastic strips of sufficient length while limiting the dimensions of the gaps, provided between the plug and the lower ring, and likely to allow the passage of dust.

Selon un mode de réalisation, la bague inférieure est reliée à la jupe périphérique externe par des ponts frangibles.According to one embodiment, the lower ring is connected to the external peripheral skirt by frangible bridges.

Selon un mode de réalisation, le dispositif de bouchage est venu de moulage en une seule pièce.According to one embodiment, the capping device is molded in one piece.

Selon un mode de réalisation, les lamelles et le dispositif de blocage sont configurés de telle sorte que, lors du mouvement de pivotement du bouchon entre la position fermée et la position basculée ouverte, les lamelles soient soumises à une force de traction qui augmente jusqu'à une position instable intermédiaire puis qui décroit de ladite position instable intermédiaire vers la position basculée ouverte.According to one embodiment, the slats and the blocking device are configured such that, during the pivoting movement of the cap between the closed position and the tilted open position, the slats are subjected to a traction force which increases until to an intermediate unstable position then which decreases from said intermediate unstable position towards the open tilted position.

Selon un mode de réalisation, lorsque le bouchon est dans la position basculée ouverte et que le deuxième secteur de la bague inférieure est dans la position abaissée, l'angle d'ouverture du bouchon est supérieur à 120° et avantageusement, supérieure ou égale à 145°, et par exemple de l'ordre de 180°.According to one embodiment, when the cap is in the open tilted position and the second sector of the lower ring is in the lowered position, the opening angle of the cap is greater than 120° and advantageously, greater than or equal to 145°, and for example of the order of 180°.

Dans la description et les figures, l'axe X correspond à l'axe de rotation du bouchon 1 du dispositif de bouchage lorsque celui-ci est vissé sur le col 2 du récipient. Par convention, l'orientation « radiale » est dirigée orthogonalement à l'axe X et l'orientation axiale est dirigée parallèlement à l'axe X. Les termes « externe » et « interne » sont utilisés pour définir la position relative d'un élément par rapport à un autre, par référence à l'axe X, un élément proche de l'axe X est ainsi qualifié d'interne par opposition à un élément externe situé radialement en périphérie.In the description and the figures, the axis By convention, the "radial" orientation is directed orthogonal to the X axis and the axial orientation is directed parallel to the X axis. The terms "external" and "internal" are used to define the relative position of a element in relation to a other, with reference to the X axis, an element close to the X axis is thus qualified as internal as opposed to an external element located radially on the periphery.

Les termes « supérieur » et « inférieur » sont utilisés pour définir la position relative d'un élément par rapport à un autre par référence à une position dans laquelle l'orifice 3 du col 2 est dirigé vers le haut et le bouchon 1 est en position de fermeture sur le col 2 du récipient, un élément destiné à être placé plus bas étant désigné par inférieur et un élément destiné à être placé plus haut étant désigné par supérieur. Les termes « avant » et « arrière » sont utilisés pour définir la position relative d'un élément par rapport à un autre le long d'un diamètre perpendiculaire à l'axe X.The terms "upper" and "lower" are used to define the relative position of one element with respect to another with reference to a position in which the orifice 3 of the neck 2 is directed upwards and the plug 1 is in closed position on the neck 2 of the container, an element intended to be placed lower being designated by lower and an element intended to be placed higher being designated by upper. The terms "front" and "back" are used to define the relative position of one element to another along a diameter perpendicular to the X axis.

En relation avec les figures 1 à 6, il est décrit ci-dessous un ensemble comprenant un dispositif de bouchage, notamment représenté sur la figure 1, et un récipient équipé d'un col 2, notamment représenté sur la figure 2.In relation to the figures 1 to 6 , an assembly is described below comprising a capping device, in particular shown on the figure 1 , and a container equipped with a neck 2, in particular shown on the figure 2 .

Comme représenté sur la figure 2, le col 2 du récipient comporte une extrémité supérieure dans laquelle est ménagé un orifice 3 permettant de déverser le contenu du récipient. Le col 2 du récipient comporte un collier de support 4 qui fait saillie radialement vers l'extérieur et une collerette d'accrochage 5 qui fait également saillie radialement vers l'extérieur et qui est disposée axialement entre le collier de support 4 et l'orifice 3. Une portion cylindrique est ménagée axialement entre le collier de support 4 et l'orifice 3. Par ailleurs, le col 2 comporte, positionné axialement entre la collerette d'accrochage 5 et l'orifice 3, un filetage hélicoïdal 6 formé d'une série de nervures hélicoïdales, faisant saillie radialement vers l'extérieur depuis une surface externe du col 2. Le filetage hélicoïdal 6 est destiné à coopérer avec un filetage hélicoïdal 7 complémentaire, représenté notamment sur la figure 5, formé d'une série de nervures hélicoïdales qui sont ménagées dans le bouchon 1 du dispositif de bouchage.As shown on the figure 2 , the neck 2 of the container has an upper end in which an orifice 3 is provided allowing the contents of the container to be poured out. The neck 2 of the container comprises a support collar 4 which projects radially outwards and a hooking collar 5 which also projects radially outwards and which is arranged axially between the support collar 4 and the orifice 3. A cylindrical portion is provided axially between the support collar 4 and the orifice 3. Furthermore, the neck 2 comprises, positioned axially between the attachment flange 5 and the orifice 3, a helical thread 6 formed of a series of helical ribs, projecting radially outwards from an external surface of the neck 2. The helical thread 6 is intended to cooperate with a complementary helical thread 7, shown in particular on the Figure 5 , formed of a series of helical ribs which are provided in the cap 1 of the capping device.

Selon un mode de réalisation, le filetage hélicoïdal 6 ménagé dans le col 2 ainsi que le filetage hélicoïdal 7 ménagé dans le bouchon 1 sont interrompus. En d'autres termes, les nervures hélicoïdales adjacentes sont séparées par un espace formant évent et permettant notamment d'évacuer le gaz présent à l'intérieur du récipient alors que le bouchon 1 est toujours en prise sur le col 2.According to one embodiment, the helical thread 6 provided in the neck 2 as well as the helical thread 7 provided in the cap 1 are interrupted. In other words, the adjacent helical ribs are separated by a space forming a vent and allowing in particular to evacuate the gas present inside the container while the cap 1 is still engaged on the neck 2.

Le dispositif de bouchage comporte une bague inférieure 9 qui est retenue sur le col 2 du récipient, un bouchon 1 qui est destiné à recouvrir l'orifice 3 du récipient de manière à l'obturer et un dispositif d'articulation 10 liant le bouchon 1 à la bague inférieure 9. Le bouchon 1 est mobile entre une position de fermeture, représentée sur la figure 1 et une position libérée, représentée sur la figure 3, dans laquelle, le bouchon 1 n'est plus en prise avec le col 2. Le bouchon 1 est en outre apte à être basculé de la position libérée vers la position basculée ouverte, représentée sur les figures 5 et 6, dans laquelle le bouchon 1 est dégagé de l'orifice 3 du col 2 de manière à ce qu'il ne gêne pas le déversement du contenu du récipient. Le dispositif de bouchage comporte également un dispositif de blocage agencé pour bloquer le bouchon 1 dans la position basculée ouverte.The capping device comprises a lower ring 9 which is retained on the neck 2 of the container, a cap 1 which is intended to cover the orifice 3 of the container so as to close it and a hinge device 10 connecting the cap 1 to the lower ring 9. The cap 1 is movable between a closed position, shown on the figure 1 and a released position, shown on the Figure 3 , in which the cap 1 is no longer engaged with the neck 2. The cap 1 is also capable of being tilted from the released position to the open tilted position, shown on the figures 5 and 6 , in which the cap 1 is released from the orifice 3 of the neck 2 so that it does not hinder the pouring of the contents of the container. The capping device also includes a blocking device arranged to block the cap 1 in the tilted open position.

Comme représenté notamment sur la figure 1, le bouchon 1 comporte une paroi supérieure 13 destinée à être disposée sensiblement orthogonalement à l'axe X, en regard de l'orifice 3 du col 2 lorsque ledit bouchon 1 est en position de fermeture. Le bouchon 1 comporte, en outre, une jupe périphérique externe 14 destinée à entourer le col 2 du récipient lorsque le bouchon 1 est en position de fermeture. La jupe périphérique externe 14 s'étend, vers le bas, perpendiculairement à la paroi supérieure 13, depuis la périphérie externe de ladite paroi supérieure 13. Le filetage hélicoïdal 7 est ménagé sur la face interne de la jupe périphérique externe 14.As shown in particular on the figure 1 , the cap 1 has an upper wall 13 intended to be arranged substantially orthogonal to the axis X, facing the orifice 3 of the neck 2 when said cap 1 is in the closed position. The cap 1 further comprises an external peripheral skirt 14 intended to surround the neck 2 of the container when the cap 1 is in the closed position. The external peripheral skirt 14 extends downwards, perpendicular to the upper wall 13, from the external periphery of said upper wall 13. The helical thread 7 is provided on the internal face of the external peripheral skirt 14.

Comme représenté notamment sur les figures 5 et 6, le bouchon 1 comporte une jupe interne 8, qui s'étend perpendiculairement vers le bas depuis la paroi supérieure 13 du bouchon 1 et est dimensionnée de manière à s'insérer à l'intérieur de l'orifice 3 du col 2. Le bouchon 1 comporte en outre une lèvre annulaire 15 qui s'étend, depuis la paroi supérieure 13, radialement entre la jupe interne 8 et la jupe périphérique externe 14. La jupe interne 8 et la lèvre annulaire 15 sont dimensionnées de telle sorte que, lorsque le bouchon 1 est en position de fermeture, sur le col 2 du récipient, la jupe interne 8 est en contact contre la face interne du col 2 tandis que la lèvre annulaire 15 est en contact contre la face externe du col 2. Ainsi, la jupe interne 8 et la lèvre annulaire 15 permettent d'assurer l'étanchéité de la fermeture.As shown in particular on the figures 5 and 6 , the cap 1 comprises an internal skirt 8, which extends perpendicularly downwards from the upper wall 13 of the cap 1 and is dimensioned so as to be inserted inside the orifice 3 of the neck 2. The cap 1 further comprises an annular lip 15 which extends, from the upper wall 13, radially between the internal skirt 8 and the external peripheral skirt 14. The internal skirt 8 and the annular lip 15 are dimensioned such that, when the cap 1 is in the closed position, on the neck 2 of the container, the internal skirt 8 is in contact against the internal face of the neck 2 while the annular lip 15 is in contact against the external face of the neck 2. Thus, the skirt internal 8 and the annular lip 15 ensure the tightness of the closure.

De manière avantageuse, la bague inférieure 9 est, avant la première ouverture du récipient, reliée au bouchon 1 par des ponts frangibles, non visibles sur les figures, destinés à se rompre lors de l'ouverture du bouchon 1. Ces ponts frangibles constituent ainsi des témoins d'inviolabilité.Advantageously, the lower ring 9 is, before the first opening of the container, connected to the cap 1 by frangible bridges, not visible in the figures, intended to break when opening the cap 1. These frangible bridges thus constitute witnesses of inviolability.

La bague inférieure 9 est maintenue axialement sur le col 2 du récipient tout en pouvant tourner par rapport à celui-ci autour de l'axe X. Comme représenté sur les figures 1, 3 et 4, la bague inférieure 9 comporte deux parties qui sont articulées l'une à l'autre, à savoir un premier secteur 16 et un deuxième secteur 17 par lequel la bague inférieure 9 est liée au bouchon 1 au moyen du dispositif d'articulation 10.The lower ring 9 is held axially on the neck 2 of the container while being able to rotate relative to the latter around the axis figures 1 , 3 and 4 , the lower ring 9 comprises two parts which are articulated to one another, namely a first sector 16 and a second sector 17 by which the lower ring 9 is linked to the plug 1 by means of the articulation device 10.

Selon un mode de réalisation, la bague inférieure 9 comporte deux zones amincies, c'est-à-dire dont l'épaisseur radiale est inférieure à l'épaisseur radiale de la bague inférieure 9 en dehors desdites zones amincies. Les deux zones amincies délimitent le premier secteur 16 et le deuxième secteur 17. Les zones amincies forment ainsi des pivots permettant l'articulation du deuxième secteur 17 par rapport au premier secteur 16. Selon un autre mode de réalisation, la bague inférieure 9 ne comporte pas de zones amincies délimitant les premier et deuxième secteurs 16, 17.According to one embodiment, the lower ring 9 comprises two thinned zones, that is to say whose radial thickness is less than the radial thickness of the lower ring 9 outside said thinned zones. The two thinned zones delimit the first sector 16 and the second sector 17. The thinned zones thus form pivots allowing the articulation of the second sector 17 relative to the first sector 16. According to another embodiment, the lower ring 9 does not include no thinned zones delimiting the first and second sectors 16, 17.

Comme représenté sur la figure 3, le deuxième secteur 17 est apte à pivoter vers le haut par rapport au premier secteur 16, entre une position abaissée dans laquelle le deuxième secteur 17 est destiné à être disposé en-dessous de la collerette d'accrochage 5 et une position relevée, dans laquelle le deuxième secteur 17 est disposé au moins en partie au-dessus de la collerette d'accrochage 5. Ceci autorise le bouchon 1 à se déplacer vers le haut par rapport au col 2 du récipient, jusqu'à ce que le filetage hélicoïdal 7 du bouchon 1 se désengage du filetage hélicoïdal 6 ménagé sur le col 2 du récipient. En d'autres termes, lorsque le bouchon 1 est dévissé, la bague inférieure 9 est entraînée en rotation autour de l'axe X tandis que le deuxième secteur 17 de la bague inférieure 9 pivote par rapport au premier secteur 16 jusqu'à la position relevée de sorte à autoriser un mouvement axial, vers le haut du bouchon 1, de la position de fermeture, jusqu'à la position libérée représentée sur la figure 3. Lorsque le bouchon 1 est pivoté de la position libérée vers la position basculée ouverte, le deuxième secteur 17 de la bague inférieure 9 pivote en sens inverse par rapport au premier secteur 16 et retrouve alors la position abaissée. Par ailleurs, comme décrit de manière plus détaillée par la suite, le deuxième secteur 17 pivote également par rapport au premier secteur 16 de la position abaissée vers la position relevée lorsque le bouchon 1 est pivoté de la position basculée ouverte vers la position libérée.As shown on the Figure 3 , the second sector 17 is capable of pivoting upwards relative to the first sector 16, between a lowered position in which the second sector 17 is intended to be arranged below the attachment flange 5 and a raised position, in which the second sector 17 is arranged at least partly above the attachment flange 5. This allows the plug 1 to move upwards relative to the neck 2 of the container, until the helical thread 7 of the cap 1 disengages from the helical thread 6 provided on the neck 2 of the container. In other words, when the cap 1 is unscrewed, the lower ring 9 is rotated around the axis raised so as to allow axial movement, upwards of the cap 1, from the closed position, to the released position shown on the Figure 3 . When the cap 1 is pivoted from the released position to the open tilted position, the second sector 17 of the lower ring 9 pivots in the opposite direction relative to the first sector 16 and then returns to the lowered position. Furthermore, as described in more detail below, the second sector 17 also pivots relative to the first sector 16 from the lowered position towards the raised position when the cap 1 is pivoted from the open tilted position to the released position.

La bague inférieure 9 est maintenue axialement sur le col 2 du récipient au moyen de la collerette d'accrochage 5. Comme représenté sur la figure 2, la collerette d'accrochage 5 présente une surface externe tronconique se rétrécissant vers le haut, c'est-à-dire en direction de l'orifice 3 du récipient. La collerette d'accrochage 5 délimite, vers le bas, c'est-à-dire dans une direction opposée à l'orifice 3, un épaulement.The lower ring 9 is held axially on the neck 2 of the container by means of the hooking collar 5. As shown in the figure 2 , the attachment collar 5 has a frustoconical external surface tapering upwards, that is to say in the direction of the orifice 3 of the container. The attachment collar 5 delimits, downwards, that is to say in a direction opposite to the orifice 3, a shoulder.

Comme représenté sur la figure 4, le premier secteur 16 de la bague inférieure 9 comporte des éléments d'accrochage 18 qui coopèrent avec la collerette d'accrochage 5 ménagée sur le récipient afin de retenir axialement la bague inférieure 9 au col 2 du récipient. Les éléments d'accrochage 18 sont des protubérances qui font saillie radialement vers l'intérieur depuis le premier secteur 16 de la bague inférieure 9. Les éléments d'accrochage 18 présentent une dimension radiale qui augmente, du bas vers le haut, c'est-à-dire en direction du bord supérieur de la bague inférieure 9. Lors de l'assemblage du dispositif de bouchage sur le col 2 du récipient, les éléments d'accrochage 18 glissent contre la surface tronconique de la collerette d'accrochage 5 puis se verrouillent par rappel élastique derrière la collerette d'accrochage 5.As shown on the Figure 4 , the first sector 16 of the lower ring 9 comprises hooking elements 18 which cooperate with the hooking collar 5 provided on the container in order to axially retain the lower ring 9 to the neck 2 of the container. The hooking elements 18 are protuberances which project radially inwards from the first sector 16 of the lower ring 9. The hooking elements 18 have a radial dimension which increases, from bottom to top, this is that is to say towards the upper edge of the lower ring 9. When assembling the capping device on the neck 2 of the container, the hooking elements 18 slide against the frustoconical surface of the hooking collar 5 then lock by elastic return behind the attachment collar 5.

Le premier secteur 16 de la bague inférieure 9 comporte une zone avant 19 qui est diamétralement opposée au deuxième secteur 17 de la bague inférieure 9 et deux zones d'accrochage 20, dont l'une est représentée sur la figure 4, qui sont disposées de part et d'autre de la zone avant 19 et sont chacune disposées entre la zone avant 19 et le deuxième secteur 17 de la bague inférieure 9. Selon un mode de réalisation, les éléments d'accrochage 18 sont uniquement disposés dans les deux zones d'accrochage 20, 21. Ainsi, en raison de l'absence d'éléments d'accrochage 18 dans la zone avant du premier secteur 16, il existe un jeu radial (désigné e4 par la suite) entre la bague inférieure 9 et le col 2 qui permet à la bague inférieure 9 de se déplacer de l'avant vers l'arrière et inversement. Le jeu radial e4 entre la bague inférieure 9 et le col 2 selon la direction avant/arrière est par exemple compris entre 0.5 et 1 mm. Ceci permet de faciliter le passage d'une partie du deuxième secteur 17 de part et d'autre de la collerette d'accrochage 5 lors du mouvement du deuxième secteur 17 entre la position abaissée et la position relevée. En d'autres termes, les efforts de traction à exercer sur la bague inférieure 9 pour permettre au deuxième secteur 17 de passer de part et d'autre de la collerette d'accrochage 5 sont moindres.The first sector 16 of the lower ring 9 comprises a front zone 19 which is diametrically opposite to the second sector 17 of the lower ring 9 and two attachment zones 20, one of which is shown on the Figure 4 , which are arranged on either side of the front zone 19 and are each arranged between the front zone 19 and the second sector 17 of the lower ring 9. According to one embodiment, the hooking elements 18 are only arranged in the two hooking zones 20, 21. Thus, due to the absence of hooking elements 18 in the front zone of the first sector 16, there is a radial clearance (designated e4 hereinafter) between the ring lower 9 and the collar 2 which allows the lower ring 9 to move from front to rear and vice versa. The radial clearance e4 between the lower ring 9 and the neck 2 in the front/rear direction is for example between 0.5 and 1 mm. This makes it possible to facilitate the passage of part of the second sector 17 on both sides. other of the attachment collar 5 during the movement of the second sector 17 between the lowered position and the raised position. In other words, the tensile forces to be exerted on the lower ring 9 to allow the second sector 17 to pass on either side of the attachment collar 5 are less.

Dans le mode de réalisation représenté, le dispositif d'articulation 10 comporte deux lamelles 11, 12, notamment visibles sur la figure 4, qui relient le bouchon 1 et plus particulièrement la jupe périphérique externe 14 du bouchon 1 à la bague inférieure 9, et plus particulièrement au deuxième secteur 17 de la bague inférieure 9. Les lamelles 11, 12 sont symétriques l'une à l'autre par rapport à un plan de symétrie P, représenté sur les figures 8 et 9, qui est vertical et passe par l'axe X.In the embodiment shown, the articulation device 10 comprises two lamellae 11, 12, in particular visible on the figure 4 , which connect the plug 1 and more particularly the external peripheral skirt 14 of the plug 1 to the lower ring 9, and more particularly to the second sector 17 of the lower ring 9. The strips 11, 12 are symmetrical to each other with respect to a plane of symmetry P, represented on the figures 8 And 9 , which is vertical and passes through the X axis.

En revenant à la figure 1, on observe que les lamelles 11, 12 rejoignent la jupe périphérique externe 14 dans une portion échancrée. De même, les lamelles 11, 12 rejoignent de manière avantageuse le deuxième secteur 17 de la bague inférieure 2 dans une portion échancrée. En d'autres termes, les lamelles 11, 12 s'étendent sensiblement au-dessus de la limite inférieure de la jupe périphérique externe 9 et s'étendent sensiblement en dessous de la limite supérieure de la bague inférieure 3.Returning to the figure 1 , we observe that the slats 11, 12 join the external peripheral skirt 14 in a notched portion. Likewise, the strips 11, 12 advantageously join the second sector 17 of the lower ring 2 in a notched portion. In other words, the strips 11, 12 extend substantially above the lower limit of the external peripheral skirt 9 and extend substantially below the upper limit of the lower ring 3.

Le dispositif de blocage comporte un talon 22, notamment visible sur les figures 1, 5 et 6, qui est ménagé dans la jupe périphérique externe 14 du bouchon 1. Le talon 22 fait saillie axialement vers le bas, c'est-à-dire en direction de la bague inférieure 9, depuis la jupe périphérique externe 14 du bouchon 1. Le talon 22 fait saillie entre les deux lamelles 11, 12. Le talon 22 comporte un taquet 23 qui s'étend circonférentiellement entre les deux lamelles 11,12 et qui fait saillie radialement vers l'extérieur depuis le talon 22.The blocking device includes a heel 22, particularly visible on the figures 1 , 5 and 6 , which is provided in the external peripheral skirt 14 of the cap 1. The heel 22 projects axially downwards, that is to say in the direction of the lower ring 9, from the external peripheral skirt 14 of the cap 1. The heel 22 projects between the two slats 11, 12. The heel 22 includes a tab 23 which extends circumferentially between the two slats 11, 12 and which projects radially outwards from the heel 22.

Le dispositif de blocage comporte également une portion en saillie 24 qui fait saillie axialement vers le haut, c'est-à-dire vers la jupe périphérique externe 14 du bouchon 1, depuis le deuxième secteur 17 de la bague inférieure 9. La portion en saillie 24 fait également saillie entre les deux lamelles 11, 12.The blocking device also comprises a projecting portion 24 which projects axially upwards, that is to say towards the external peripheral skirt 14 of the plug 1, from the second sector 17 of the lower ring 9. The portion in projection 24 also projects between the two strips 11, 12.

Comme représenté sur les figures 5 et 6, le taquet 23 et la portion en saillie 24 sont agencés de telle sorte que, lorsque le bouchon 1 est en position basculée ouverte, la portion en saillie 24 est prise en sandwich entre le taquet 23 et la collerette d'accrochage 5. En d'autres termes, lorsque le bouchon est en position basculée ouverte, le taquet 23 et la portion en saillie 24 sont en contact l'un contre l'autre dans une zone située dans le plan de la collerette d'accrochage 5 et la portion en saillie 24 est également en contact contre la collerette d'accrochage 5.As shown on the figures 5 and 6 , the tab 23 and the projecting portion 24 are arranged such that, when the cap 1 is in the tilted open position, the projecting portion 24 is sandwiched between the tab 23 and the collar hooking 5. In other words, when the cap is in the open tilted position, the tab 23 and the projecting portion 24 are in contact with one another in a zone located in the plane of the flange d hooking 5 and the projecting portion 24 is also in contact against the hooking collar 5.

Comme représenté respectivement sur les figures 8 et 9, la zone de contact du taquet 23 avec la portion en saillie 24 est placée à une distance radiale e1 de l'intersection entre la droite passant par les extrémités supérieures des lamelles 11, 12 et le plan de symétrie P et la zone de contact de la portion en saillie 24 avec le taquet 23 est placée à une distance radiale e2 de l'intersection entre la droite passant par les extrémités inférieures des lamelles 11, 12 et le plan de symétrie P.As shown respectively on the figures 8 And 9 , the contact zone of the tab 23 with the projecting portion 24 is placed at a radial distance e1 from the intersection between the straight line passing through the upper ends of the strips 11, 12 and the plane of symmetry P and the contact zone of the projecting portion 24 with the tab 23 is placed at a radial distance e2 from the intersection between the line passing through the lower ends of the slats 11, 12 and the plane of symmetry P.

La dimension e1 est telle que e1 > L - e2, avec L : la longueur des lamelles 11, 12, à l'état initial, lorsque le bouchon est dans la position de fermeture. Ceci assure que le taquet 23 vienne en contact contre la portion en saillie 24 et que les lamelles 11, 12 soient contraintes en traction lorsque le bouchon 1 est dans la position basculée ouverte.The dimension e1 is such that e1 > L - e2, with L: the length of the strips 11, 12, in the initial state, when the cap is in the closed position. This ensures that the tab 23 comes into contact against the projecting portion 24 and that the strips 11, 12 are stressed in traction when the plug 1 is in the open tilted position.

En outre, e1 >L - e2 + e3 + e4 avec e3 : le jeu radial entre la portion en saillie 24 et la collerette d'accrochage 5 et e4 : le jeu radial entre la bague inférieure 9 et le col 2 selon la direction avant/arrière, c'est à-dire selon une direction radiale à l'axe X et inscrite dans le plan de symétrie P. De préférence, e1 = L - e2 + e3 + e4+ Δ avec Δ compris entre 0,05 et 2 mm, et déterminé de sorte que la portion en saillie 24 vienne en contact contre la collerette d'accrochage 5 lorsque le bouchon 1 est dans la position basculée ouverte.In addition, e1 >L - e2 + e3 + e4 with e3: the radial clearance between the projecting portion 24 and the attachment flange 5 and e4: the radial clearance between the lower ring 9 and the neck 2 in the forward direction /rear, that is to say in a direction radial to the axis , and determined so that the projecting portion 24 comes into contact against the hooking collar 5 when the plug 1 is in the open tilted position.

Par ailleurs, comme représenté sur la figure 7, lorsque le bouchon 1 est en position basculée ouverte, le bord supérieur de la surface de contact du taquet 23 s'étend axialement en-dessous de l'extrémité supérieure des lamelles 11, 12 d'un distance d1, le bord supérieur de la portion en saillie 24 s'étend axialement au-dessus de l'extrémité inférieure des lamelles 11, 12 d'une distance d2 et le bord supérieur de collerette d'accrochage 5 s'étend axialement au-dessus de l'extrémité inférieure des lamelles 11, 12 d'une distance d3. De manière avantageuse, la distance d1 est inférieure à d2 et à d3.Furthermore, as shown in the Figure 7 , when the cap 1 is in the open tilted position, the upper edge of the contact surface of the tab 23 extends axially below the upper end of the strips 11, 12 by a distance d1, the upper edge of the projecting portion 24 extends axially above the lower end of the slats 11, 12 by a distance d2 and the upper edge of the attachment flange 5 extends axially above the lower end of the slats 11, 12 from a distance d3. Advantageously, the distance d1 is less than d2 and d3.

La cinématique du bouchon 1 est la suivante. Lors du premier dévissage, le bouchon 1 quitte la position de fermeture et s'éloigne de la bague inférieure 9 jusqu'à la position libérée, illustrée sur la figure 3. Les ponts frangibles se rompent au cours de ce mouvement. En outre, lors de ce mouvement de dévissage du bouchon 1, la bague inférieure 9 est entraînée en rotation autour de l'axe X et le deuxième secteur 17 de la bague inférieure 9 pivote vers la position relevée au fur et à mesure que le bouchon 1 s'éloigne de la collerette d'accrochage 5.The kinematics of cap 1 are as follows. During the first unscrewing, the cap 1 leaves the closed position and moves away from the lower ring 9 to the released position, illustrated on the Figure 3 . Frangible bridges break during this movement. Furthermore, during this movement of unscrewing the cap 1, the lower ring 9 is rotated around the axis X and the second sector 17 of the lower ring 9 pivots towards the raised position as the cap 1 moves away from the attachment collar 5.

Par la suite, le bouchon 1 peut alors être pivoté vers l'arrière en direction de la position basculée ouverte dans laquelle la jupe périphérique externe 14 s'étend vers le haut depuis la paroi supérieure 13. Lors du mouvement du bouchon 1 vers l'arrière en direction de sa position basculée ouverte, le taquet 23 vient en appui contre la portion en saillie 24 et entraîne ainsi le pivotement du deuxième secteur 17 de la bague inférieure 9 pivote de la position relevée vers la position abaissée.Subsequently, the cap 1 can then be pivoted rearward towards the open tilted position in which the outer peripheral skirt 14 extends upwards from the upper wall 13. When the cap 1 moves towards the rear towards its open tilted position, the tab 23 comes to bear against the projecting portion 24 and thus causes the pivoting of the second sector 17 of the lower ring 9 pivots from the raised position to the lowered position.

Les possibilités d'étirement des lamelles 11, 10 conjointement aux caractéristiques précitées du dispositif de blocage, permettent de créer un point dur lors du basculement du bouchon 1 entre la position libérée, représentée sur la figure 3, et la position basculée ouverte, représentée sur les figures 4 et 5. En d'autres termes, les lamelles 11, 12 ainsi que le dispositif de blocage sont configurés de telle sorte que, durant une première partie du mouvement du bouchon 4 de la position libérée vers la position basculée ouverte, les deux lamelles élastiques 28, 29 sont, en raison de l'appui du taquet 23 sur la portion en saillie 24, soumis à une force de traction qui augmente jusqu'à une position instable intermédiaire puis qui décroit de ladite position instable intermédiaire vers la position basculée ouverte. Ceci permet de bloquer le bouchon 1 dans la position basculée ouverte.The possibilities of stretching the strips 11, 10 together with the aforementioned characteristics of the blocking device, make it possible to create a hard point when the plug 1 tilts between the released position, shown on the Figure 3 , and the tilted open position, shown on the figures 4 And 5 . In other words, the slats 11, 12 as well as the blocking device are configured such that, during a first part of the movement of the plug 4 from the released position to the open tilted position, the two elastic slats 28, 29 are, due to the support of the cleat 23 on the projecting portion 24, subjected to a traction force which increases to an intermediate unstable position then which decreases from said intermediate unstable position towards the open tilted position. This makes it possible to block the cap 1 in the tilted open position.

Comme représenté sur les figures 5 et 6, lorsque le deuxième secteur 17 de la bague inférieure 9 est dans la position abaissée et que le bouchon 1 est dans sa position basculée ouverte, le taquet 23 est en appui contre la portion en saillie 24 qui se trouve ainsi prise en sandwich entre ledit taquet 23 et la collerette d'accrochage 5.As shown on the figures 5 and 6 , when the second sector 17 of the lower ring 9 is in the lowered position and the plug 1 is in its tilted open position, the tab 23 rests against the projecting portion 24 which is thus sandwiched between said tab 23 and the hanging collar 5.

Ainsi, le bouchon 1 demeure dans sa position basculée ouverte puisque, en raison de la disposition précitée, le bouchon 1 ne peut pas être pivoté vers la position libérée dans laquelle le bouchon 1 est en regard de l'orifice 3 de distribution tant que le deuxième secteur 17 de la bague inférieure 9 reste dans la position abaissée.Thus, the cap 1 remains in its tilted open position since, due to the aforementioned arrangement, the cap 1 cannot be pivoted towards the released position in which the plug 1 faces the distribution orifice 3 as long as the second sector 17 of the lower ring 9 remains in the lowered position.

De manière avantageuse, lorsque le bouchon 1 est dans sa position basculée ouverte et que le deuxième secteur 17 de la bague inférieure 9 est dans la position abaissée, l'angle d'ouverture du bouchon 1 est supérieur à 120° et avantageusement, supérieure ou égale à 145° et par exemple de l'ordre de 180°. L'angle d'ouverture correspond au secteur angulaire saillant qui est formé à l'intersection entre un plan parallèle à la paroi supérieure 13 du bouchon 1 et un plan horizontal.Advantageously, when the cap 1 is in its open tilted position and the second sector 17 of the lower ring 9 is in the lowered position, the opening angle of the cap 1 is greater than 120° and advantageously, greater than or equal to 145° and for example of the order of 180°. The opening angle corresponds to the protruding angular sector which is formed at the intersection between a plane parallel to the upper wall 13 of the plug 1 and a horizontal plane.

Pour refermer le bouchon 1, l'utilisateur bascule le bouchon 1 vers l'avant jusqu'à la position libérée. Lors de ce basculement, le contact entre le taquet 23 et la portion en saillie 24 disparait, ce qui autorise le mouvement du deuxième secteur 17 de la bague inférieure 9 vers la position relevée.To close cap 1, the user tilts cap 1 forward to the released position. During this tilting, the contact between the tab 23 and the projecting portion 24 disappears, which allows the movement of the second sector 17 of the lower ring 9 towards the raised position.

Lorsque le deuxième secteur 17 est dans la position relevée et que le bouchon 1 est dans la position libérée, ledit bouchon 1 peut alors être revissé sur le col 2 du récipient. Lors du revissage, la bague inférieure 9 est entraînée en rotation autour de l'axe X et le deuxième secteur 17 de la bague inférieure 9 pivote vers la position abaissée au fur et à mesure que le bouchon 1 s'approche de la collerette d'accrochage 5.When the second sector 17 is in the raised position and the cap 1 is in the released position, said cap 1 can then be screwed back onto the neck 2 of the container. When screwing back, the lower ring 9 is rotated around the axis hooking 5.

De manière avantageuse, l'ensemble du dispositif de bouchage est venu de moulage en une seule pièce de matière synthétique, tel que du polyéthylène et avantageusement du polyéthylène haute densité. De manière avantageuse, le dispositif de bouchage est moulé dans la configuration de la figure 1, c'est-à-dire dans une position de fermeture, position dans laquelle il peut être directement monté sur le col 2 du récipient.Advantageously, the entire closure device is molded in a single piece of synthetic material, such as polyethylene and advantageously high density polyethylene. Advantageously, the capping device is molded in the configuration of the figure 1 , that is to say in a closed position, position in which it can be directly mounted on the neck 2 of the container.
