Description

La présente invention concerne un bouchon destiné à être placé sur le goulot d'un récipient, typiquement sur une bouteille de champagne.The present invention relates to a cap to be placed on the neck of a container, typically on a bottle of champagne.

Un premier type de bouchon de champagne connu est inséré dans le goulot de façon à assurer l'étanchéité. A cet effet, il peut être mis en place à force ou être de diamètre plus réduit mais avoir la propriété de s'élargir pour venir obturer toute la section du goulot. Toutefois, dans ces deux cas, s'il existe une surpression dans la bouteille, le bouchon risque d'être éjecté, ce qui est dangereux.A first type of known champagne cork is inserted into the neck so as to seal. For this purpose, it can be set up by force or be smaller in diameter but have the property of widening to close the entire section of the neck. However, in both cases, if there is an overpressure in the bottle, the cap may be ejected, which is dangerous.

Un deuxième type de bouchon de champagne connu comporte une partie souple, appelée tétine, qui vient en appui sur le bord supérieur du goulot, et qui forme une seule pièce avec un capuchon. Deux branches identiques sont articulées sur le capuchon autour d'un axe horizontal solidaire du capuchon, et donc de la tétine. Pour fermer la bouteille, on rapproche les branches l'une de l'autre, en les rabattant contre le goulot. Les branches venant alors s'encliqueter sous une collerette du goulot, maintenant ainsi la tétine en appui étanche contre le bord supérieur du goulot.A second type of known champagne plug has a flexible portion, called pacifier, which bears on the upper edge of the neck, and which forms a single piece with a cap. Two identical branches are articulated on the cap around a horizontal axis integral with the cap, and therefore the nipple. To close the bottle, we bring the branches together, by folding them against the neck. The branches then snap under a collar of the neck, thus maintaining the nipple sealingly against the upper edge of the neck.

Ce type de bouchon donne généralement satisfaction. Toutefois, à la fois pour obtenir un centrage convenable du bouchon sur le goulot et pour actionner simultanément les deux branches, la mise en place d'un tel bouchon nécessite les deux mains de l'utilisateur, qui ne peut donc pas en plus tenir la bouteille.This type of plug generally gives satisfaction. However, both to obtain a proper centering of the stopper on the neck and to operate simultaneously the two branches, the establishment of such a stopper requires both hands of the user, which therefore can not also hold the bottle.

Un autre type de bouchon est décrit dans les documents EP 0 323 886 et FR 2 622 543 . Ces bouchons sont toutefois complexes à monter.Another type of plug is described in the documents EP 0 323 886 and FR 2 622 543 . These plugs are however complex to mount.

La présente invention vise à remédier aux inconvénients mentionnés ci-dessus, en fournissant un bouchon, notamment pour une bouteille de champagne, qui soit d'une mise en place aisée et qui permette de garantir une bonne étanchéité et la sécurité des utilisateurs. Un autre objectif de l'invention est de fournir un bouchon qui soit d'un montage simple.The present invention aims to overcome the drawbacks mentioned above, by providing a plug, especially for a bottle of champagne, which is easy to set up and which ensures a good seal and user safety. Another object of the invention is to provide a plug that is a simple assembly.

A cet effet, l'invention concerne un bouchon destiné à être placé sur le goulot d'un récipient tel qu'une bouteille de champagne, ledit goulot présentant un axe et comportant un bord supérieur et une collerette annulaire, le bouchon comprenant :

  • une coiffe sensiblement rigide comportant d'une part une paroi supérieure et d'autre part une jupe faisant saillie globalement perpendiculairement de la paroi supérieure depuis le bord périphérique de celle-ci, uniquement sur une portion dudit bord périphérique, de façon à définir une ouverture latérale, ladite jupe comportant un bourrelet intérieur apte à coopérer avec la face inférieure de la collerette du goulot ;
  • un organe d'étanchéité présentant un axe qui, en position montée du bouchon sur le goulot, est sensiblement confondu avec l'axe du goulot, ledit organe d'étanchéité comportant une face apte à coopérer avec étanchéité avec le bord supérieur du goulot lorsque le bourrelet coopère avec la collerette, afin de permettre le maintien du bouchon sur le goulot et la fermeture sensiblement étanche du récipient ;
For this purpose, the invention relates to a cap intended to be placed on the neck of a container such as a champagne bottle, said neck having an axis and having an upper edge and an annular flange, the cap comprising:
  • a substantially rigid cap comprising on the one hand an upper wall and on the other hand a skirt projecting generally perpendicularly from the upper wall from the peripheral edge of it, only on a portion of said peripheral edge, so as to define a lateral opening, said skirt having an inner bead adapted to cooperate with the underside of the flange of the neck;
  • a sealing member having an axis which, in the mounted position of the stopper on the neck, is substantially coincidental with the axis of the neck, said sealing member having a face adapted to cooperate sealingly with the upper edge of the neck when the bead cooperates with the collar, to allow the maintenance of the cap on the neck and the substantially sealed closure of the container;

l'organe d'étanchéité étant monté sur la coiffe de façon pivotante autour d'un axe de pivotement sensiblement orthogonal à l'axe de l'organe d'étanchéité, entre :

  • une position écartée de la coiffe, dans laquelle la paroi supérieure fait un angle aigu non droit avec l'axe de l'organe d'étanchéité, pour permettre la mise en place du bouchon sur le goulot ;
  • et une position rabattue de la coiffe, le goulot s'étant engagé dans la coiffe par l'ouverture latérale de celle-ci, dans laquelle la paroi supérieure est sensiblement orthogonale à l'axe de l'organe d'étanchéité et le bourrelet coopère avec la collerette, pour permettre le maintien du bouchon sur le goulot avec étanchéité,
the sealing member being mounted on the cap pivotally about a pivot axis substantially orthogonal to the axis of the sealing member, between:
  • a position spaced from the cap, in which the upper wall makes an acute angle not right with the axis of the sealing member, to allow the introduction of the cap on the neck;
  • and a folded position of the cap, the neck being engaged in the cap by the lateral opening thereof, wherein the upper wall is substantially orthogonal to the axis of the sealing member and the bead cooperates with the collar, to allow the maintenance of the cap on the neck with sealing,

l'organe d'étanchéité comprenant au moins un téton radial apte à être engagé par encliquetage dans une encoche ménagée sur la coiffe, à l'intérieur de celle-ci, pour former l'axe de pivotement de l'organe d'étanchéité par rapport à la coiffe.the sealing member comprising at least one radial stud adapted to be engaged by snapping into a notch provided on the cap, inside thereof, to form the axis of pivoting of the sealing member by compared to the cap.

Les termes « supérieur », « inférieur » et analogue sont utilisés par rapport à l'axe du récipient lorsque celui-ci est vertical, le récipient reposant sur son fond, ce qui correspond généralement à la position de mise en place du bouchon. Le terme « intérieur » désigne des éléments situés près de cet axe, ou tournés vers cet axe.The terms "upper", "lower" and the like are used relative to the axis of the container when it is vertical, the container resting on its bottom, which generally corresponds to the position of introduction of the cap. The term "interior" refers to elements located near this axis, or facing this axis.

Ainsi, et contrairement aux bouchons connus, le bouchon selon l'invention comprend d'une part une coiffe incluant une paroi supérieure et une jupe, typiquement réalisée d'une seule pièce, et d'autre part un organe d'étanchéité distinct de la coiffe et articulé sur celle-ci, à l'intérieur de celle-ci.Thus, and contrary to known plugs, the stopper according to the invention comprises on the one hand a cap including an upper wall and a skirt, typically made in one piece, and on the other hand a sealing member separate from the cap and articulated on it, inside of it.

Une caractéristique importante de l'invention est que cette coiffe comporte une jupe qui ne fait pas tout le tour de la coiffe. En d'autres termes, le bouchon ne comporte qu'une seule branche qui vient se cliper sous la collerette du goulot.An important feature of the invention is that this cap has a skirt that does not all around the cap. In other words, the cap has only one branch that comes to clip under the collar of the neck.

En pratique, la position écartée de la coiffe permet l'introduction de l'organe d'étanchéité dans le goulot. Puis, lors du pivotement de la coiffe, l'organe d'étanchéité sert de guidage. Ceci, combiné au fait que l'organe d'étanchéité est articulé sur la coiffe, compense le déséquilibre créé par la présence d'une unique branche - la jupe - sur la coiffe, qui conduirait à un positionnement « en travers » du bouchon par rapport au goulot. Enfin, en position rabattue, la coiffe enveloppe le goulot, et le goulot est pris en sandwich, avec serrage axial, entre la face de l'organe d'étanchéité en appui sur le bord supérieur du goulot et le bourrelet de la coiffe en appui sous la collerette.In practice, the position away from the cap allows the introduction of the sealing member in the neck. Then, during the pivoting of the cap, the sealing member serves as a guide. This, combined with the fact that the sealing member is articulated on the cap, compensates for the imbalance created by the presence of a single branch - the skirt - on the cap, which would lead to a "cross" position of the cap by compared to the bottleneck. Finally, in the folded position, the cap wraps around the neck, and the neck is sandwiched, with axial clamping, between the face of the sealing member resting on the upper edge of the neck and the bead of the support cap under the collar.

Ainsi, le bouchon selon l'invention est facile à mettre en place d'une seule main - l'autre main maintenant le récipient - et ce sans risque de positionnement en biais qui pourrait notamment nuire à l'étanchéité. Cet avantage est obtenu quel que soit le goulot, notamment quel que soit son diamètre ou si ce diamètre est irrégulier.Thus, the cap according to the invention is easy to set up with one hand - the other hand now the container - and without risk of skew positioning which could particularly affect the seal. This advantage is obtained regardless of the neck, especially regardless of its diameter or if this diameter is irregular.

Ce bouchon remplit la double fonction de fermeture du récipient de façon étanche et de sécurité puisque, en cas de surpression, l'organe d'étanchéité peut se décoller du bord supérieur du goulot et permettre ainsi à l'air de fuir, évitant donc l'éjection du bouchon.This plug fulfills the double function of closing the container in a sealed and safe manner since, in the event of overpressure, the sealing member can be detached from the upper edge of the neck and thus allow the air to escape, thus avoiding the ejection of the plug.

De plus, l'existence d'une jupe unique venant se cliper sous la collerette du goulot - par opposition à deux branches distinctes articulées - confère à ce bouchon une esthétique particulière, sans pour autant nuire à l'efficacité du maintien du bouchon sur le goulot. En outre, cette jupe peut offrir une grande surface pouvant recevoir des ornements ou des informations, notamment publicitaires.In addition, the existence of a single skirt that clip under the collar of the neck - as opposed to two separate branches articulated - gives this cap a particular aesthetic, without affecting the effectiveness of maintaining the cap on the neck. In addition, this skirt can offer a large area that can receive ornaments or information, including advertising.

Par ailleurs, le montage de l'organe d'étanchéité sur la coiffe par encliquetage du ou des tétons radiaux est très simple à mettre en oeuvre en pratique.Furthermore, the mounting of the sealing member on the cap by snapping the radial stud or pins is very simple to implement in practice.

Par exemple, la coiffe comporte deux pattes sensiblement parallèles faisant saillie sensiblement perpendiculairement de la paroi supérieure, dans le même sens que la jupe, chaque patte comportant une encoche ouverte vers l'ouverture latérale de la coiffe, et l'organe d'étanchéité comporte un appendice supérieur pourvu de deux tétons latéraux, l'appendice étant logé entre les deux pattes lorsque l'organe d'étanchéité est assemblé à la coiffe. Le positionnement intérieur, sensiblement caché, de l'axe de pivotement, contribue à améliorer l'esthétique du bouchon.For example, the cap comprises two substantially parallel tabs projecting substantially perpendicularly from the upper wall, in the same direction as the skirt, each tab having a notch open towards the lateral opening of the cap, and the sealing member comprises an upper appendage provided with two lateral pins, the appendix being housed between the two lugs when the sealing member is assembled to the cap. The substantially hidden internal positioning of the pivot axis contributes to improving the aesthetics of the cap.

Avantageusement, l'axe de pivotement de l'organe d'étanchéité par rapport à la coiffe est situé à proximité immédiate de la face inférieure de la paroi supérieure de la coiffe, typiquement juste en-dessous de cette paroi supérieure.Advantageously, the axis of pivoting of the sealing member relative to the cap is located in the immediate vicinity of the lower face of the upper wall of the cap, typically just below this upper wall.

L'organe d'étanchéité peut comprendre une portion d'appui dont une face inférieure est apte à coopérer avec le bord supérieur du goulot et un élément inférieur apte à être inséré dans le goulot.The sealing member may comprise a bearing portion of which a lower face is adapted to cooperate with the upper edge of the neck and a lower member adapted to be inserted into the neck.

L'élément inférieur peut présenter une cavité intérieure ouverte vers le bas. De ce fait, l'élément inférieur voit son diamètre augmenter sous l'effet de la pression régnant dans le récipient, et vient se coller contre la paroi intérieure du goulot, améliorant ainsi l'étanchéité.The lower element may have an interior cavity open downward. As a result, the lower element sees its diameter increase under the effect of the pressure in the container, and sticks against the inner wall of the neck, thus improving the seal.

Avantageusement, la jupe de la coiffe peut s'étendre le long du bord périphérique de la paroi supérieure sur un angle compris entre 240 et 280°, par exemple sur environ 270°. En prévoyant une jupe s'étendant dans cette gamme d'angles, on libère une ouverture suffisante pour le passage du goulot lors de la mise en place du bouchon, tout en fournissant un bourrelet de longueur suffisante pour assurer la retenue efficace du bouchon sur le goulot.Advantageously, the skirt of the cap may extend along the peripheral edge of the upper wall at an angle of between 240 and 280 °, for example about 270 °. By providing a skirt extending in this range of angles, it releases an opening sufficient for the passage of the neck during the introduction of the cap, while providing a bead of sufficient length to ensure effective retention of the cap on the neck.

Selon une réalisation possible, les bords latéraux de la jupe de la coiffe, qui délimitent l'ouverture latérale, sont incurvés, de sorte que ladite jupe présente deux languettes inférieures. Ceci permet d'augmenter la longueur périphérique du bourrelet, et donc d'améliorer le maintien du bouchon. En outre, cela allège le bouchon par rapport à une structure où les bords latéraux de la jupe seraient parallèles à l'axe du goulot - en position montée et rabattue de la coiffe. Outre un gain de matière, on obtient un effet esthétique.According to one possible embodiment, the lateral edges of the skirt of the cap, which delimit the lateral opening, are curved, so that said skirt has two lower tongues. This makes it possible to increase the peripheral length of the bead, and thus to improve the maintenance of the plug. In addition, this lighten the cap relative to a structure where the lateral edges of the skirt would be parallel to the axis of the neck - in the assembled and folded position of the cap. In addition to a material gain, we obtain an aesthetic effect.

Au moins certaines des parties de l'organe d'étanchéité destinées à être en contact avec le goulot du récipient peuvent être réalisées en un matériau élastiquement déformable, par exemple en un élastomère alimentaire. Ceci permet d'absorber les différences de diamètre du goulot et les différentes hauteurs de collerette. Le bouchon peut donc plus facilement s'adapter à des goulots différents. De plus, le risque d'éjection est encore diminué, car l'organe d'étanchéité peut aussi absorber les différences de pression lors de l'ouverture du récipient.At least some of the parts of the sealing member intended to be in contact with the neck of the container may be made of an elastically deformable material, for example a food elastomer. This makes it possible to absorb the differences in the diameter of the neck and the different collar heights. The cap can therefore more easily adapt to different necks. In addition, the risk of ejection is further reduced, because the sealing member can also absorb pressure differences when opening the container.

On décrit à présent, à titre d'exemple non limitatif, un mode de réalisation possible de l'invention, en référence aux figures annexées :

  • Les figures 1 et 2 sont des vues en perspective d'un bouchon selon l'invention, la coiffe étant respectivement en position rabattue et en position écartée ;
  • Les figures 3 et 4 sont des vues similaires aux figures 1 et 2, le bouchon étant vu latéralement ;
  • Les figures 5 et 6 sont des vues similaires aux figures 1 et 2, le bouchon étant vu de dessous ;
  • Les figures 7 à 9 illustrent trois étapes successives de la mise en place du bouchon sur le goulot d'un récipient.
We will now describe, by way of nonlimiting example, a possible embodiment of the invention, with reference to the appended figures:
  • The Figures 1 and 2 are perspective views of a cap according to the invention, the cap being respectively in the folded position and in the separated position;
  • The Figures 3 and 4 are similar views to Figures 1 and 2 , the plug being seen laterally;
  • The Figures 5 and 6 are similar views to Figures 1 and 2 , the cap being seen from below;
  • The Figures 7 to 9 illustrate three successive stages of the introduction of the cap on the neck of a container.

Comme illustré sur les figures 1 à 6, un bouchon 1 selon l'invention comprend d'une part une coiffe 2 et d'autre part un organe d'étanchéité 3.As illustrated on Figures 1 to 6 , a plug 1 according to the invention comprises on the one hand a cap 2 and on the other hand a sealing member 3.

Un tel bouchon 1 est destiné à permettre la fermeture étanche d'un récipient, typiquement une bouteille de champagne, comme représenté sur les figures 7 à 9. Ce récipient comporte un goulot 4 d'axe 5 (représenté verticalement sur les figures). Le goulot 4 possède une face intérieure 6 sensiblement cylindrique et une face extérieure 7. Le goulot 4 comporte un bord supérieur 8 sensiblement annulaire, plan et orthogonal à l'axe 5, et une collerette annulaire 9 faisant saillie depuis la face extérieure 7, à distance sous le bord supérieur 8.Such a cap 1 is intended to allow the tight closure of a container, typically a bottle of champagne, as shown on the Figures 7 to 9 . This container has a neck 4 axis 5 (shown vertically in the figures). The neck 4 has a substantially cylindrical inner face 6 and an outer face 7. The neck 4 has a substantially annular upper edge 8, plane and orthogonal to the axis 5, and an annular flange 9 projecting from the outer face 7, to distance under the upper edge 8.

La coiffe 2 est sensiblement rigide et réalisée d'une seule pièce. Elle peut par exemple être obtenue par moulage d'une matière plastique ou métallique. Elle présente ici un axe 10.The cap 2 is substantially rigid and made in one piece. It may for example be obtained by molding a plastic or metal material. Here it presents an axis 10.

La coiffe 2 comporte une paroi supérieure 11 qui est ici globalement plane et en forme de disque orthogonal à l'axe 10, et qui présente un bord périphérique circulaire 12. En outre, la coiffe 2 comporte une jupe 13 qui fait saillie globalement perpendiculairement de la paroi supérieure 11 depuis le bord périphérique 12, sur environ 270°. La jupe 13 présente un bord inférieur 14 situé sensiblement dans un plan orthogonal à l'axe 10 et deux bords latéraux 15a, 15b. Les bords latéraux 15a, 15b sont incurvés et définissent ainsi deux languettes 16a, 16b inférieures arrondies. Les deux bords latéraux 15a, 15b de la jupe 13 et la partie du bord périphérique 12 non attenante à la jupe 13 délimitent une ouverture 17 latérale permettant l'accès au volume intérieur de la coiffe 2. De plus, la jupe 13 comporte un bourrelet 18 intérieur s'étendant globalement orthogonalement à l'axe 10, d'une languette 16a à l'autre 16b.The cap 2 has an upper wall 11 which is here generally planar and disk-shaped orthogonal to the axis 10, and which has a circular peripheral edge 12. In addition, the cap 2 comprises a skirt 13 which protrudes generally perpendicularly from the upper wall 11 from the peripheral edge 12, about 270 °. The skirt 13 has a lower edge 14 located substantially in a plane orthogonal to the axis 10 and two side edges 15a, 15b. The lateral edges 15a, 15b are curved and thus define two tongues 16a, 16b rounded lower. The two lateral edges 15a, 15b of the skirt 13 and the portion of the peripheral edge 12 not adjacent to the skirt 13 define a lateral opening 17 allowing access to the interior volume of the cap 2. In addition, the skirt 13 comprises a bead 18 extending generally orthogonal to the axis 10, a tab 16a to the other 16b.

La coiffe 2 comporte également deux pattes 20a, 20b sensiblement identiques et parallèles faisant saillie sensiblement perpendiculairement de la paroi supérieure 11 dans le même sens que la jupe 13. Chaque patte 20a, 20b comporte une encoche 21 ouverte vers l'ouverture 17 latérale, les deux encoches 21 étant alignées selon un axe 22 perpendiculaire à l'axe 10 de la coiffe 2 et situé juste en-dessous de la paroi supérieure 11.The cap 2 also comprises two substantially identical and parallel tabs 20a, 20b protruding substantially perpendicularly from the upper wall 11 in the same direction as the skirt 13. Each lug 20a, 20b has a notch 21 open towards the lateral opening 17, the two notches 21 being aligned along an axis 22 perpendicular to the axis 10 of the cap 2 and located just below the upper wall 11.

L'organe d'étanchéité 3 présente un axe 23. Il comprend un corps 24 comportant un appendice 25 supérieur rigide pourvu de deux tétons 26 latéraux s'étendant de part et d'autre de l'appendice 25, de façon alignée selon un axe orthogonal à l'axe 23. De plus, l'organe d'étanchéité 3 comporte un insert 27 monté dans le corps 24, et dépassant sous celui-ci. L'insert 27 est réalisé en un matériau déformable, typiquement en un élastomère alimentaire. L'insert 27 comporte une partie inférieure qui présente, à l'état non contraint, un diamètre extérieur inférieur au diamètre intérieur du goulot, et qui possède une cavité 28 intérieure ouverte vers le bas.The sealing member 3 has an axis 23. It comprises a body 24 having a rigid upper appendage 25 provided with two lateral studs 26 extending on either side of the appendage 25, aligned along an axis orthogonal to the axis 23. In addition, the sealing member 3 comprises an insert 27 mounted in the body 24, and protruding below it. The insert 27 is made of a deformable material, typically a food elastomer. The insert 27 has a lower portion which has, in the unconstrained state, an outside diameter less than the inside diameter of the neck, and which has an interior cavity 28 open downwards.

L'organe d'étanchéité 3 est monté dans la coiffe 2 par encliquetage des tétons 26 dans les encoches 21 de la coiffe 2, l'appendice 25 étant donc logé entre les deux pattes 20a, 20b. Est ainsi défini un axe de pivotement de l'organe d'étanchéité 3 par rapport à la coiffe qui est confondu avec l'axe 22 des encoches 21 et qui est orthogonal à l'axe 23 de l'organe d'étanchéité 3.The sealing member 3 is mounted in the cap 2 by snapping the pins 26 into the notches 21 of the cap 2, the appendage 25 being housed between the two tabs 20a, 20b. Is thus defined a pivot axis of the sealing member 3 relative to the cap which coincides with the axis 22 of the notches 21 and which is orthogonal to the axis 23 of the sealing member 3.

La coiffe 2 peut ainsi occuper une position écartée (figures 2, 4 et 6) dans laquelle la paroi supérieure 11 de la coiffe 2 fait un angle aigu non droit avec l'axe 23 de l'organe d'étanchéité 3. En d'autres termes, il existe un angle α aigu et non nul, ici de l'ordre de 30 à 50°, entre l'axe 10 de la coiffe 2 et l'axe 23 de l'organe d'étanchéité 3.The cap 2 can thus occupy a remote position ( Figures 2, 4 and 6 ) in which the upper wall 11 of the cap 2 makes an acute right angle with the axis 23 of the sealing member 3. In other words, there is an acute angle α and not zero, here the order of 30 to 50 °, between the axis 10 of the cap 2 and the axis 23 of the sealing member 3.

De plus, la coiffe 2 peut pivoter autour de l'axe 22 jusqu'à une position rabattue (figures 1, 3 et 5) dans laquelle la paroi supérieure 11 est sensiblement orthogonale à l'axe 23 de l'organe d'étanchéité 3.In addition, the cap 2 can pivot about the axis 22 to a folded position ( Figures 1, 3 and 5 ) in which the upper wall 11 is substantially orthogonal to the axis 23 of the sealing member 3.

La mise en place du bouchon sur le goulot 4 s'effectue comme suit.The introduction of the cap on the neck 4 is performed as follows.

Tout d'abord, comme illustré sur la figure 7, l'organe d'étanchéité 3 est inséré dans le goulot 4, les axes 23 de l'organe d'étanchéité 3 et 5 du goulot étant sensiblement confondus. Pour permettre cette insertion, la coiffe 2 est placée dans la position écartée.First of all, as illustrated on the figure 7 , the sealing member 3 is inserted into the neck 4, the axes 23 of the sealing member 3 and 5 of the neck being substantially merged. To allow this insertion, the cap 2 is placed in the remote position.

En fin d'insertion (figure 8), l'organe d'étanchéité 3 est en appui contre le bord supérieur 8 du goulot 4 et la partie inférieure de l'insert 27 est logée dans le goulot 4. Un utilisateur fait alors pivoter la coiffe 2 autour de l'axe 22. Au cours de ce pivotement, l'organe d'étanchéité 3, et plus précisément la partie inférieure de l'insert 27, sert de guidage et empêche un basculement de l'organe d'étanchéité 3. La coiffe 2 vient progressivement recevoir le goulot 4 et l'organe d'étanchéité 3 dans son volume intérieur, depuis l'ouverture 17.At the end of insertion ( figure 8 ), the sealing member 3 is in abutment against the upper edge 8 of the neck 4 and the lower part of the insert 27 is housed in the neck 4. A user then rotates the cap 2 around the axis 22. During this pivoting, the sealing member 3, and more precisely the lower part of the insert 27, serves as a guide and prevents tilting of the sealing member 3. The cap 2 gradually comes to receive the neck 4 and the sealing member 3 in its interior volume, since the opening 17.

En position rabattue (figure 9), le bourrelet 18 coopère avec la face inférieure de la collerette 9, encliquetant ainsi le bouchon 1 sur le goulot 4. Le goulot est donc serré axialement entre l'organe d'étanchéité 3 en appui étanche sur le bord supérieur 8 et le bourrelet 18 placé sous la collerette 9, d'un seul côté du goulot 4. On obtient ainsi un très bon maintien du bouchon 1 sur le goulot 4 et la fermeture sensiblement étanche du récipient.In the folded position ( figure 9 ), the bead 18 cooperates with the underside of the flange 9, thus snapping the cap 1 on the neck 4. The neck is thus clamped axially between the sealing member 3 in sealing engagement on the upper edge 8 and the bead 18 is placed under the flange 9 on one side of the neck 4. This provides a very good maintenance of the cap 1 on the neck 4 and the substantially sealed closure of the container.

Il va de soi que l'invention n'est pas limitée au mode de réalisation décrit ci-dessus à titre d'exemple mais qu'elle comprend tous les équivalents techniques et les variantes des moyens décrits ainsi que leurs combinaisons.It goes without saying that the invention is not limited to the embodiment described above by way of example but that it includes all the technical equivalents and variants of the means described as well as their combinations.
