Description

Domaine technique de l'inventionTechnical field of the invention

La présente invention concerne un bouchon pour récipient à col fileté. L'invention concerne plus particulièrement un bouchon qui est inséparable du récipient même lorsque le bouchon est ouvert.The present invention relates to a cap for a container with a threaded neck. The invention relates more particularly to a stopper which is inseparable from the container even when the stopper is open.

Arrière-plan techniqueTechnical background

Il est connu qu'un récipient à col fileté tel qu'une bouteille peut être muni d'un col sur lequel est fixé par vissage un bouchon. Le terme de récipient désigne ici toute sorte de contenants, sans limitation de forme ni d'utilisation. Le bouchon comporte par exemple un corps de bouchon comprenant une jupe de forme tubulaire et un plateau relié à sa périphérie à la jupe et destiné à venir recouvrir l'ouverture du col. La jupe comporte un filet disposé à l'intérieur, destiné à venir en prise avec une forme complémentaire du col d'un récipient.It is known that a container with a threaded neck such as a bottle can be provided with a neck on which a cap is fixed by screwing. The term container here designates all kinds of containers, without limitation of form or use. The stopper comprises for example a stopper body comprising a tubular shaped skirt and a plate connected at its periphery to the skirt and intended to cover the opening of the neck. The skirt comprises a net disposed inside, intended to come into engagement with a complementary shape of the neck of a container.

La jupe est fréquemment prolongée par une bague d'inviolabilité destinée à venir en prise avec une collerette du col. La bague d'inviolabilité est reliée à la jupe par des ponts entre lesquels s'étendent des séparations traversantes. Lors de l'ouverture du bouchon, la bague d'inviolabilité reste accrochée à la collerette et se détache de la jupe par la rupture des ponts. Ceci permet de montrer que le flacon a déjà été ouvert.The skirt is frequently extended by a tamper-evident ring intended to engage with a collar of the collar. The tamper-evident ring is connected to the skirt by bridges between which extend through partitions. When opening the cap, the tamper-evident ring remains attached to the collar and is detached from the skirt by breaking the bridges. This shows that the bottle has already been opened.

Récemment, les nouvelles directives européennes ont mis en place une norme exigeant que les bouchons basiques tels que décrits ci-dessus doivent désormais être reliés au col de la bouteille, afin de limiter l'impact de la pollution sur l'environnement par rejet de ces bouchons.Recently, the new European directives set up a standard requiring that the basic stoppers as described above must now be connected to the neck of the bottle, in order to limit the impact of pollution on the environment by rejecting these. caps.

Ainsi, le développement de certains récipients ne sera possible que dans la mesure où leur bouchon est attaché au reste du récipient afin qu'ils ne soient plus séparés, perdus dans la nature et ensuite ingérés par des animaux. C'est dans ce contexte que nous avons vu développer des bouchons qui sont inséparables du récipient, quel que soit leur état de fermeture ou d'ouverture.Thus, the development of certain containers will only be possible insofar as their cap is attached to the rest of the container so that they are no longer separated, lost in nature and then ingested by animals. It is in this context that we have seen the development of stoppers which are inseparable from the container, whatever their state of closure or opening.

Ces bouchons inséparables, dits bouchons de nouvelle génération, comprennent les mêmes éléments que des bouchons conventionnels sauf que le corps de bouchon est lié en permanence à la bague d'inviolabilité au moyen des bras de liaison. Ces bras de liaison sont conformés par leur longueur de manière à permettre au corps de bouchon de s'éloigner axialement la bague d'inviolabilité, de se détacher du col et de pouvoir basculer à une position d'ouverture dans laquelle l'accès au récipient est libéré.These inseparable caps, called new generation caps, include the same elements as conventional caps except that the cap body is permanently linked to the tamper-evident ring by means of the link arms. These connecting arms are shaped by their length so as to allow the stopper body to move away axially from the tamper-evident ring, to detach from the neck and to be able to switch to an open position in which access to the container is released.

Le document US 5215204 décrit un exemple de réalisation de ce type de bouchon.The document US 5215204 describes an exemplary embodiment of this type of stopper.

Cependant, le bouchon inséparable tel que décrit présente l'inconvénient qu'une fois que le corps de bouchon est dans la position d'ouverture, les bras de liaison, en combinaison avec la force élastique des charnières, tendent à ramener le corps de bouchon au-dessus de l'ouverture du col. Ceci crée un état semi-ouvert du récipient, c'est-à-dire un état dans lequel l'ouverture du col est partiellement libérée. Cet état semi-ouvert gêne l'écoulement du liquide hors du récipient et oblige l'utilisateur à tenir le corps du bouchon dans une position ouverture pour laquelle l'ouverture du col est complètement libérée.However, the inseparable stopper as described has the disadvantage that once the stopper body is in the open position, the link arms, in combination with the elastic force of the hinges, tend to pull the stopper body back. above the neck opening. This creates a semi-open state of the container, i.e. a state in which the opening of the neck is partially released. This semi-open state hinders the flow of liquid out of the container and forces the user to hold the body of the stopper in an open position for which the opening of the neck is completely released.

Ainsi, l'invention a pour objectif de proposer un bouchon assurant la bonne étanchéité de la bouteille et garantissant l'inviolabilité. Ce bouchon est pratique à utiliser tout en garantissant un confort d'utilisation.Thus, the object of the invention is to provide a stopper ensuring good sealing of the bottle and guaranteeing inviolability. This cap is practical to use while ensuring comfort of use.

Résumé de l'inventionSummary of the invention

Avec ces objectifs en vue, l'invention propose un bouchon pour récipient à col fileté, comprenant :

  • un corps de bouchon comprenant une jupe sensiblement tubulaire centrée sur un axe longitudinal et des moyens pour sa venue en prise avec le col du récipient, le corps de bouchon étant monté pivotant entre une position de fermeture dans laquelle le corps de bouchon obture une ouverture du col et une position d'ouverture dans laquelle le corps de bouchon est dégagé de l'ouverture du corps pour permettre l'accès à l'intérieur du récipient ;
  • une bague d'inviolabilité centrée sur l'axe longitudinal et comprenant des moyens pour sa venue en prise avec une collerette du col ; et
  • deux bras de liaison s'étendant selon une direction angulaire, les bras de liaison étant reliés d'une part à la bague d'inviolabilité et d'autre part au corps de bouchon.
With these objectives in view, the invention provides a stopper for a container with a threaded neck, comprising:
  • a stopper body comprising a substantially tubular skirt centered on a longitudinal axis and means for its engagement with the neck of the container, the stopper body being mounted to pivot between a closed position in which the stopper body closes an opening of the neck and an open position in which the stopper body is disengaged from the opening of the body to allow access to the interior of the container;
  • a tamper-evident ring centered on the longitudinal axis and comprising means for its engagement with a collar of the neck; and
  • two link arms extending in an angular direction, the link arms being connected on the one hand to the tamper-evident ring and on the other hand to the stopper body.

L'organe de blocage comprend une première partie située au niveau du corps de bouchon et une deuxième partie située au niveau de la bague d'inviolabilité, les première et deuxième parties étant constituées de matière pleine. Enfin, la première partie et la deuxième partie de l'organe de blocage coopèrent l'une avec l'autre par une liaison d'appui pour permettre le maintien du bouchon dans une position d'ouverture complète dans laquelle l'ouverture du col est complètement dégagée.According to the invention, the stopper comprises a locking member located between the two link arms. The locking member comprises a first part located at the level of the stopper body and a second part located at the level of the tamper-evident ring, the first and second parts being made of solid material. Finally, the first part and the second part of the locking member cooperate with each other by a support connection to allow the stopper to be kept in a fully open position in which the opening of the neck is completely clear.

A noter que le corps du bouchon est monté pivotant entre plusieurs positions d'ouverture. En effet, le corps du bouchon peut basculer de la position de fermeture à une position à peine ouverte dans laquelle seule une partie de l'ouverture du col est libérée, ou à une position d'ouverture extrême dans laquelle l'inclinaison du corps de bouchon par rapport à la bague d'inviolabilité est maximale. Lorsque le corps de bouchon est en position d'ouverture extrême, on peut aussi dire que le récipient est en position de pleine ouverture.Note that the body of the cap is mounted to pivot between several opening positions. Indeed, the body of the stopper can switch from the closed position to a barely open position in which only part of the opening of the neck is released, or to an extreme open position in which the inclination of the body of cap relative to the tamper-evident ring is maximum. When the stopper body is in the extreme open position, it can also be said that the container is in the fully open position.

La position d'ouverture complète peut être une position intermédiaire entre la position à peine ouverte et la position d'ouverture extrême. De manière générale, le corps de bouchon est dans une position d'ouverture complète lorsqu'il forme avec la bague d'inviolabilité un angle supérieur à 90°.The fully open position can be an intermediate position between the barely open position and the extreme open position. In general, the stopper body is in a fully open position when it forms an angle of greater than 90 ° with the tamper-evident ring.

Dans le bouchon proposé, l'organe de blocage est pour but de maintenir le corps de bouchon dans une position d'ouverture complète. Précisément, la première partie et la deuxième partie de l'organe de blocage s'appuient l'une sur l'autre de façon à maintenir le corps du bouchon décalé par rapport à l'ouverture du col pour qu'elle soit complètement dégagée.In the proposed stopper, the blocking member is intended to maintain the stopper body in a fully open position. Specifically, the first part and the second part of the blocking member rest on one another so as to keep the body of the stopper offset from the opening of the neck so that it is completely free.

Ainsi, l'écoulement du liquide n'est plus gêné par le corps de bouchon. Le bouchon est donc pratique à utiliser. L'utilisateur n'a qu'à ouvrir le bouchon jusqu'à ce que le corps de bouchon soit immobilisé au moyen de l'organe de blocage. Ensuite, il peut verser librement le liquide contenu dans le récipient sans avoir besoin de tenir le corps du bouchon.Thus, the flow of liquid is no longer hampered by the stopper body. The cap is therefore convenient to use. The user only has to open the stopper until the stopper body is immobilized by means of the locking member. Then it can freely pour the liquid contained in the container without needing to hold the body of the stopper.

En outre, grâce à l'organe de blocage, le bouchon garantit une sécurité de l'utilisation, car le corps de bouchon n'est plus en position de pouvoir retenir une quantité résiduelle du liquide après le versement. Autrement dit, le corps de bouchon reste sec et peut être manipulé sans gêne pour la fermeture du bouchon.In addition, thanks to the locking member, the stopper guarantees safe use, since the stopper body is no longer in a position to be able to retain a residual quantity of liquid after pouring. In other words, the stopper body remains dry and can be handled without hindrance for closing the stopper.

Description détaillée de l'inventionDetailed description of the invention

Les figures représentent un bouchon 1 destiné à être monté sur un col 21 d'un récipient 2. Le col 21 et le récipient 2 sont représentés sur les figures 8 et 9.The figures show a stopper 1 intended to be mounted on a neck 21 of a container 2. The neck 21 and the container 2 are shown in the figures. figures 8 and 9 .

Sur la figure 1, le bouchon 1 comprend un corps de bouchon 10 et une bague d'inviolabilité 11. Le corps de bouchon 10 comprend ici une jupe latérale 101 ayant une forme de cylindre droit d'axe révolution X-X'. Ledit axe est considéré comme axe longitudinal du bouchon 1. La jupe latérale 101 comprend des nervures 103 qui s'étendent tous selon l'axe longitudinal X-X' et sont réparties de manière uniforme sur toute la face externe de la jupe latérale 101. Ainsi, ces nervures 103 permettent une meilleure accroche des doigts de l'utilisateur au corps de bouchon 10 lorsqu'il saisit le corps de bouchon 10 pour ouvrir ou fermer le bouchon 1.On the figure 1 , the stopper 1 comprises a stopper body 10 and a tamper-evident ring 11. The stopper body 10 here comprises a side skirt 101 having the shape of a right cylinder of revolution axis X-X '. Said axis is considered to be the longitudinal axis of the stopper 1. The side skirt 101 comprises ribs 103 which all extend along the longitudinal axis XX 'and are distributed uniformly over the entire outer face of the side skirt 101. Thus, these ribs 103 allow better grip of the user's fingers to the stopper body 10 when he grasps the stopper body 10 to open or close the stopper 1.

Le corps de bouchon 10 comprend en outre un plateau 102 orienté perpendiculairement à l'axe longitudinal X-X' et relié à sa périphérie à la jupe latérale 101. Le plateau 102 forme ainsi un fond du bouchon 1.The stopper body 10 further comprises a plate 102 oriented perpendicularly to the longitudinal axis X-X 'and connected at its periphery to the side skirt 101. The plate 102 thus forms a bottom of the stopper 1.

De manière connue et comme observé sur la figure 9, le corps de bouchon 10 comprend en outre les nervures hélicoïdales 108 qui sont destinées à venir en prise avec des nervures hélicoïdales complémentaires 24 qui sont pratiquées sur le col 20 du récipient 2. Les nervures hélicoïdales 108 du corps de bouchon sont réalisées sur une face interne de la jupe latérale 101. Une bague d'inviolabilité 11 est dans le prolongement de la jupe latérale 101 du corps de bouchon 10. La bague d'inviolabilité 11 est reliée au corps de bouchon 10 par l'intermédiaire des bras de liaison 12, ici au nombre de deux, et qui sont eux-mêmes reliés au corps de bouchon 10 via un organe de blocage 13 et des branches de maintien 14.In a known manner and as observed on the figure 9 , the stopper body 10 further comprises the helical ribs 108 which are intended to engage with complementary helical ribs 24 which are formed on the neck 20 of the container 2. The helical ribs 108 of the stopper body are formed on one side internal of the side skirt 101. A tamper-evident ring 11 is an extension of the side skirt 101 of the stopper body 10. The tamper-evident ring 11 is connected to the stopper body 10 by means of the link arms 12 , here two in number, and which are themselves connected to the stopper body 10 via a locking member 13 and holding branches 14.

En outre, avant la toute première ouverture du bouchon, le corps de bouchon 10 est relié à la bague d'inviolabilité 11 par des ponts frangibles qui sont répartis sur la circonférence du bouchon. Les ponts frangibles sont conformés pour se rompre lors de la rotation du corps de bouchon 10 par rapport à la bague d'inviolabilité 11.In addition, before the very first opening of the stopper, the stopper body 10 is connected to the tamper-evident ring 11 by frangible bridges which are distributed over the circumference of the stopper. The frangible bridges are shaped to break during the rotation of the stopper body 10 relative to the tamper-evident ring 11.

Dans l'exemple illustré, les bras de liaison 12 sont formés dans la bague d'inviolabilité 11. Pour ce faire, un évidement angulaire 113 est réalisé dans la bague 11 pour former une partie du bas 111 et une partie du haut 112 séparées par l'évidement 113. La partie du bas 111 est destinée à être attachée à une collerette du col tandis que la partie du haut 112 forme les bras de liaison 12. La jonction entre la partie du bas 111 et la partie du haut 112 marque la fin de l'évidement angulaire 113.In the example illustrated, the link arms 12 are formed in the tamper-evident ring 11. To do this, an angular recess 113 is made in the ring 11 to form a part of the bottom 111 and a part of the top 112 separated by the recess 113. The bottom part 111 is intended to be attached to a collar of the neck while the top part 112 forms the link arms 12. The junction between the bottom part 111 and the top part 112 marks the end of angular recess 113.

Ici, l'évidement angulaire 113 est continu et sert également à séparer la partie du bas 111 de l'organe de blocage 13.Here, the angular recess 113 is continuous and also serves to separate the bottom part 111 from the locking member 13.

Selon l'invention et comme dans cet exemple, le corps de bouchon 10 est monté pivotant par rapport à la bague d'inviolabilité 11 entre une position de fermeture et au moins une d'ouverture.According to the invention and as in this example, the stopper body 10 is mounted to pivot relative to the tamper-evident ring 11 between a closed position and at least one open position.

Dans la position de fermeture, le plateau 102 du corps de bouchon 10 est dans une position horizontale et située juste au-dessus une ouverture 20 du col 21 de sorte à obturer complètement cette ouverture. Ici, les termes « horizontal » et « vertical » sont définis avec un bouchon monté sur un récipient tenu debout sur une surface plane. Le récipient se tient debout selon un axe vertical. La direction horizontale est perpendiculaire à cet axe vertical. Le bouchon 1 tel qu'illustré sur la figure 1 ou sur la figure 7 est dans la position de fermeture.In the closed position, the plate 102 of the stopper body 10 is in a horizontal position and located just above an opening 20 of the neck 21 so as to completely close this opening. Here, the terms "horizontal" and "vertical" are defined with a cap mounted on a container held upright on a flat surface. The container stands upright along a vertical axis. The horizontal direction is perpendicular to this vertical axis. Cap 1 as shown on figure 1 or on the figure 7 is in the closed position.

Dans une position d'ouverture, le plateau 102 du corps de bouchon 10 ne recouvre plus la totalité de l'ouverture 20 du col, ce qui permet de libérer cette ouverture 20 et donc l'accès à l'intérieur du récipient. Ainsi, le corps de bouchon 10 en position d'ouverture permet donc de verser le liquide à partir du récipient 2.In an open position, the plate 102 of the stopper body 10 no longer covers the entire opening 20 of the neck, which makes it possible to free this opening 20 and therefore access to the interior of the container. Thus, the stopper body 10 in the open position therefore makes it possible to pour the liquid from the container 2.

Le corps de bouchon 10 peut basculer entre plusieurs positions d'ouverture parmi lesquelles il y a la position d'ouverture complète dans laquelle le corps de bouchon 10 est désaxé par rapport à l'ouverture du col et se trouve vers l'extérieur par rapport au récipient 2 de manière à laisser l'ouverture 20 à découvert. La figure 9 représente un exemple de la position d'ouverture complète du corps de bouchon 10.The stopper body 10 can switch between several open positions among which there is the fully open position in which the stopper body 10 is offset with respect to the opening of the neck and lies outwardly with respect. to the container 2 so as to leave the opening 20 uncovered. The figure 9 shows an example of the fully open position of the stopper body 10.

De plus, le corps de bouchon 10 peut se trouver aussi à une position d'ouverture extrême dans laquelle l'inclinaison de celui-ci est au maximum. Ici, dans la position d'ouverture extrême, le corps de bouchon 10 est retourné de 180° par rapport à sa position de fermeture, comme on peut le voir sur la figure 10.In addition, the stopper body 10 may also be in an extreme open position in which the inclination thereof is at the maximum. Here, in the extreme open position, the stopper body 10 is turned 180 ° from its closed position, as can be seen in the figure. figure 10 .

Le pivotement du corps de bouchon 10 est effectué au moyen des charnières 15. Celles-ci sont formées par les branches de maintien 14 présentant une épaisseur suffisamment faible pour qu'elles puissent se plier sur elle-même. L'axe des charnières 15 forme l'axe de pivotement. On définit comme direction transversale la direction qui est sensiblement parallèle à l'axe de pivotement.The cap body 10 is pivoted by means of the hinges 15. These are formed by the retaining branches 14 having a sufficiently small thickness so that they can bend on themselves. The axis of the hinges 15 forms the pivot axis. The direction which is substantially parallel to the pivot axis is defined as the transverse direction.

Selon l'invention et comme illustré dans cet exemple, l'organe de blocage 13 est disposé entre les deux bras de liaison 12 et sert à maintenir le corps de bouchon 10 dans une position d'ouverture complète, et précisément dans la position d'ouverture extrême.According to the invention and as illustrated in this example, the locking member 13 is arranged between the two link arms 12 and serves to maintain the stopper body 10 in a fully open position, and precisely in the position of. extreme opening.

Sur la figure 2, on peut observer que l'organe de blocage 13 est composé d'une première partie 131 située au niveau du corps de bouchon 10 et d'une deuxième partie 132 située au niveau de la bague d'inviolabilité 11.On the figure 2 , it can be observed that the locking member 13 is composed of a first part 131 located at the level of the stopper body 10 and of a second part 132 located at the level of the tamper-evident ring 11.

Ici, la première partie 131 est formée d'un ergot, ou une bande saillante, qui fait saillie vers l'extérieur dans une direction radiale.Here, the first part 131 is formed of a lug, or a protruding strip, which protrudes outwardly in a radial direction.

La deuxième partie 132 est formée d'un îlot de matière pleine relié de part et d'autre aux deux bras de liaison 12. Ici, l'îlot présente la forme d'un segment de cercle. Décrit autrement, l'îlot comprend une extrémité supérieure 137 qui dessine un arc de cercle.The second part 132 is formed of an island of solid material connected on either side to the two connecting arms 12. Here, the island has the shape of a segment of a circle. Described otherwise, the island includes an upper end 137 which forms an arc of a circle.

La deuxième partie 132 de l'organe de blocage 13 est reliée également à deux branches de maintien 14. Celles-ci s'étendent directement depuis le corps de bouchon 10 selon la direction longitudinale et situées respectivement de chaque côté de la première partie 131.The second part 132 of the locking member 13 is also connected to two holding branches 14. These extend directly from the stopper body 10 in the longitudinal direction and located respectively on each side of the first part 131.

Comme observé sur la figure 3, la deuxième partie 132 a une épaisseur variable selon la direction longitudinale. Plus on est proche du corps de bouchon 10, plus la deuxième partie 132 est mince. La portion la plus mince 136 de la deuxième partie est située au voisinage de l'extrémité supérieure 137.As observed on the figure 3 , the second part 132 has a variable thickness in the longitudinal direction. The closer one is to the plug body 10, the thinner the second part 132 is. The thinnest portion 136 of the second part is located in the vicinity of the upper end 137.

La portion la plus mince 136 comprend une face extérieure 135 qui est une face biseautée vers l'intérieur du bouchon. En d'autres termes, selon l'épaisseur, la portion la plus mince 136 est en forme de biseau.The thinnest portion 136 includes an exterior face 135 which is an inwardly beveled face of the cap. In other words, depending on the thickness, the thinnest portion 136 is bevel-shaped.

Ici, l'épaisseur est mesurée selon la direction radiale, la longueur est mesurée selon la direction longitudinale et la largeur est mesurée selon la direction transversale.Here, the thickness is measured in the radial direction, the length is measured in the longitudinal direction, and the width is measured in the transverse direction.

Selon l'invention et comme dans cet exemple, une gorge 134 est réalisée sur la face extérieure biseautée 135. La gorge 134 s'étend sur toute la largeur de la face extérieure biseautée 135.According to the invention and as in this example, a groove 134 is produced on the bevelled outer face 135. The groove 134 extends over the entire width of the beveled outer face 135.

La gorge 134 est conformée pour former un siège d'appui sur lequel se repose la première partie 131 et pour former un moyen pour retenir l'ergot lorsque le corps de bouchon atteint la position d'ouverture extrême, comme illustré sur la figure 4.The groove 134 is shaped to form a bearing seat on which the first part 131 rests and to form a means for retaining the lug when the stopper body reaches the extreme open position, as illustrated in the figure. figure 4 .

De manière plus précise, dans l'exemple illustré, l'ergot formant la première partie 131 de l'organe de blocage comprend un bord supérieur externe 133 qui s'appuie sur la gorge 134 lorsque le corps de bouchon 10 est dans la position d'ouverture extrême.More precisely, in the example illustrated, the lug forming the first part 131 of the locking member comprises an outer upper edge 133 which rests on the groove 134 when the stopper body 10 is in the position of. extreme openness.

La gorge 134, de par sa configuration, est bornée axialement par deux bandes 138, 139 légèrement en saillie. Ainsi, au moins la bande inférieure 139 empêche temporairement l'ergot 131 de glisser hors de la gorge 134. Autrement dit, la présence des bandes saillantes permet de retenir l'ergot 131 en appui sur la gorge 134 et de vaincre la force élastique des branches de maintien 14 formant charnière et des bras de liaison 12, qui ont tendance à rappeler le corps de bouchon 10 vers la bague d'inviolabilité 11.The groove 134, by virtue of its configuration, is axially bounded by two strips 138, 139 slightly projecting. Thus, at least the lower band 139 temporarily prevents the lug 131 from sliding out of the groove 134. In other words, the presence of the projecting bands makes it possible to retain the lug 131 resting on the groove 134 and to overcome the elastic force of the grooves. holding branches 14 forming a hinge and connecting arms 12, which tend to remind the stopper body 10 towards the tamper-evident ring 11.

De cette manière, le corps de bouchon 10 est maintenu en position d'ouverture extrême pour ne pas gêner le versement du liquide à partir du récipient. De plus, le corps de bouchon 10 se tient dans cette position sans avoir besoin d'intervention de l'utilisateur. Une fois que le versement du liquide est fini, l'utilisateur peut appliquer une force suffisante pour faire sortir l'ergot 131 de la gorge 134 et puis faire basculer le corps de bouchon dans la position de fermeture pour fermer le récipient.In this way, the stopper body 10 is kept in the extreme open position so as not to interfere with the pouring of liquid from the container. In addition, the stopper body 10 is held in this position without the need for user intervention. Once the pouring of the liquid is finished, the user can apply sufficient force to pop the lug 131 out of the groove 134 and then tilt the stopper body into the closed position to close the container.

Ici, le bord supérieur externe 133 est légèrement arrondi pour faciliter le glissement de l'ergot sur la face externe 135 de la deuxième partie 132.Here, the outer upper edge 133 is slightly rounded to facilitate the sliding of the lug on the outer face 135 of the second part 132.

Il apparaît aux figures 2, 5 et 6 que chacune des branches de maintien 14 est reliée à la deuxième partie 132. La jonction 19 entre chacune de ces branches 14 et la deuxième partie 132 présente une épaisseur e1 inférieure à celle de la deuxième partie 132 (e3) et à celle de la branche de maintien 14 (e2). Cette jonction 19 d'épaisseur moindre forme une zone souple qui accorde plus de mobilité au corps de bouchon 10, ce qui permet de faciliter la manipulation du corps de bouchon 10 lors de l'ouverture et de la fermeture du bouchon 1. La jonction 19 permet également de faciliter la flexion des branches de maintien 14 au niveau de la jonction pour assurer un bon positionnement de l'ergot 131 par rapport à la deuxième partie 132 lorsque l'ergot 131 vient en contact avec cette deuxième partie 132.It appears to figures 2 , 5 and 6 that each of the holding branches 14 is connected to the second part 132. The junction 19 between each of these branches 14 and the second part 132 has a thickness e1 less than that of the second part 132 (e3) and that of the branch hold 14 (e2). This junction 19 of lesser thickness forms a flexible zone which grants more mobility to the stopper body 10, which makes it possible to facilitate the handling of the stopper body 10 during opening and closing. of the stopper 1. The junction 19 also makes it possible to facilitate the bending of the holding branches 14 at the level of the junction to ensure a good positioning of the lug 131 relative to the second part 132 when the lug 131 comes into contact with this part two 132.

Ici, nous avons deux charnières 15, car les branches de maintien 14 sont au nombre de deux.Here we have two hinges 15, because the holding branches 14 are two in number.

Les charnières 15 sont situées au-dessus de la gorge 134. Autrement dit, les charnières 15 sont décalées axialement vers le haut par rapport à la gorge 134.The hinges 15 are located above the groove 134. In other words, the hinges 15 are offset axially upwards with respect to the groove 134.

Sur la figure 6, la jupe latérale 101 se termine en bas par un volet inférieur 104. Par une vue de dessus, le volet inférieur 104 forme un cercle ouvert avec deux extrémités libres 105. L'organe de blocage 13 et les branches de maintien 14 sont disposés dans l'espace séparant les deux extrémités libres 105 du volet 104.On the figure 6 , the side skirt 101 ends at the bottom with a lower flap 104. In a top view, the lower flap 104 forms an open circle with two free ends 105. The locking member 13 and the holding branches 14 are arranged in the space separating the two free ends 105 of the shutter 104.

Selon l'invention et comme dans cet exemple, les extrémités libres 105 du volet sont situées à distance des branches de maintien 14 de façon à former un premier espace traversant 16, s'étendant longitudinalement, entre chaque extrémité libre 105 et le côté extérieur 141 de la branche de maintien 14 correspondante. Ici, le côté extérieur 141 d'une branche de maintien 14 est celui qui est le plus éloigné de l'ergot 131 dans la direction transversale. D'un autre côté, le volet inférieur 104 est situé au-dessus et à l'écart des bras de liaison 12 de manière à former un deuxième espace traversant 17 s'étendant angulairement.According to the invention and as in this example, the free ends 105 of the shutter are located at a distance from the holding branches 14 so as to form a first through space 16, extending longitudinally, between each free end 105 and the outer side 141 of the corresponding holding branch 14. Here, the outer side 141 of a retaining branch 14 is that which is furthest from the lug 131 in the transverse direction. On the other hand, the lower flap 104 is located above and away from the link arms 12 so as to form a second through space 17 extending angularly.

Le volet inférieur 104, les branches de maintien 14 et les bras de liaison 12 sont agencées de sorte que le premier espace traversant 16 débouche dans le deuxième espace traversant 17 pour former un espace traversant résultant 18 continu qui présente une forme en L. Décrit autrement, le premier espace traversant 16 et le deuxième espace traversant 17 se joignent et forment ici un angle droit.The lower flap 104, the holding branches 14 and the link arms 12 are arranged so that the first through space 16 opens into the second through space 17 to form a resulting continuous through space 18 which has an L-shape. , the first through space 16 and the second through space 17 join and here form a right angle.

Cette disposition particulière permet d'avoir une attache solide entre le corps de bouchon et la bague d'inviolabilité tout en permettant une grande flexibilité de basculement du corps de bouchon.This particular arrangement makes it possible to have a solid attachment between the stopper body and the tamper-evident ring while allowing great flexibility in tilting the stopper body.

Les figures 7 à 9 illustrent les différentes étapes de l'ouverture du bouchon 1 décrit précédemment. L'organe de blocage 13 n'est pas illustré en détail sur ces figures.The figures 7 to 9 illustrate the different stages of opening the cap 1 described above. The locking member 13 is not illustrated in detail in these figures.

Ici, il s'agit d'une toute première ouverture du bouchon 1.Here, this is the very first opening of cap 1.

Sur la figure 7, le bouchon 1 est complètement fermé. Le corps de bouchon 10 est dans la position de fermeture. Des ponts frangibles, non représentés sur les figures, relient le corps de bouchon 10 à la bague d'inviolabilité 11. Pour ouvrir le bouchon, l'utilisateur réalise une première étape pendant laquelle il saisit le corps de bouchon 10 dans une main et le récipient 2 dans l'autre main, et ensuite l'utilisateur fait tourner le bouchon 10 dans un sens illustré par la flèche R sur la figure 7. Suite à cette action, les ponts frangibles se rompent, ce qui indique que le bouchon ou le récipient a été déjà ouvert. Le corps de bouchon 10 est désormais délié de la bague d'inviolabilité 11.On the figure 7 , cap 1 is completely closed. The stopper body 10 is in the closed position. Frangible bridges, not shown in the figures, connect the stopper body 10 to the tamper-evident ring 11. To open the stopper, the user performs a first step during which he grasps the stopper body 10 in one hand and holds it. container 2 in the other hand, and then the user turns the cap 10 in a direction illustrated by the arrow R on the figure 7 . As a result of this action, the frangible bridges break, indicating that the cap or container has already been opened. The stopper body 10 is now unbound from the tamper-evident ring 11.

A l'étape suivante, l'utilisateur soulève le corps de bouchon 10 pour l'éloigner axialement de la bague d'inviolabilité 11 comme illustré sur la figure 8. Les bras de liaison 12 se ploient progressivement avec la montée du corps de bouchon 10. L'élasticité des bras de liaison 12 permet cet éloignement du corps de bouchon 10 de la bague d'inviolabilité.In the next step, the user lifts the stopper body 10 to move it axially away from the tamper-evident ring 11 as illustrated in figure figure 8 . The link arms 12 gradually bend with the rise of the stopper body 10. The elasticity of the link arms 12 allows the stopper body 10 to be moved away from the tamper-evident ring.

Ensuite, le corps de bouchon 10 bascule vers l'extérieur du récipient 2 en faisant un pivotement autour de l'axe des charnières 15. Le corps de bouchon 10 atteint une position d'ouverture complète comme illustré sur la figure 9.Then, the stopper body 10 swings out of the container 2 by pivoting about the axis of the hinges 15. The stopper body 10 reaches a fully open position as illustrated in the figure. figure 9 .

Enfin, dans l'exemple illustré et comme montré sur la figure 10, le corps de bouchon 10 continue à pivoter jusqu'à atteindre la position d'ouverture extrême qui sera maintenue par l'organe de blocage 13.Finally, in the example illustrated and as shown on figure 10 , the stopper body 10 continues to pivot until it reaches the extreme open position which will be maintained by the locking member 13.

Le bouchon 1 décrit à titre illustratif de l'objet de l'invention présente plusieurs avantages. Le bouchon assure la bonne étanchéité du récipient tout en indiquant l'état d'usage de ce récipient, s'il est déjà ouvert ou non. Le bouchon, par l'organe de blocage, est maintenu ouvert et libère complètement l'ouverture du col pour ne pas gêner l'écoulement du liquide. Enfin, en restant dans la position ouverte complète, le bouchon, précisément le corps de bouchon, ne sera pas au contact du liquide sortant du récipient et restera sec pendant et après le versement du liquide..The stopper 1 described by way of illustration of the subject of the invention has several advantages. The cap ensures a good seal of the container while indicating the state of use of this container, whether it is already open or not. the stopper, by the blocking member, is kept open and completely frees the opening of the neck so as not to obstruct the flow of the liquid. Finally, by remaining in the fully open position, the stopper, precisely the stopper body, will not come into contact with the liquid leaving the container and will remain dry during and after pouring the liquid.
