Description

La présente invention se rapporte à une boîte cylindrique comprenant un réceptacle et un dispositif de bouchage en liège pour venir boucher le réceptacle.The present invention relates to a cylindrical box comprising a receptacle and a cork closure device to come to plug the receptacle.

Un domaine d'application envisagé est notamment, mais non exclusivement, celui du stockage de denrées alimentaires qu'il convient de préserver vis-à-vis de l'air extérieur à la boîte.One envisaged field of application is in particular, but not exclusively, that of the storage of foodstuffs which should be preserved vis-à-vis the air outside the box.

Des boîtes cylindriques connues comportent un réceptacle cylindrique à courbe directrice circulaire et un dispositif de bouchage composite comprenant une partie en liège et une partie faite d'un matériau polymère. Ainsi, le réceptacle, usuellement réalisé dans un matériau à base cellulosique, présente un bord circulaire et une ouverture délimitée par ledit bord circulaire. S'agissant du dispositif de bouchage, il présente un épaulement délimitant l'une de l'autre, une partie de préhension et une partie de bouchage d'un diamètre inférieur à celui de la partie de préhension. Et la partie de bouchage, de symétrie cylindrique, présente une bande de contact et une face libre sensiblement perpendiculaire, recouvertes d'une couche d'un matériau polymère.Known cylindrical boxes include a cylindrical receptacle with a circular guide curve and a composite closure device comprising a cork portion and a portion made of a polymeric material. Thus, the receptacle, usually made of a cellulosic material, has a circular edge and an opening delimited by said circular edge. As regards the closure device, it has a shoulder delimiting one of the other, a gripping portion and a capping portion of a diameter smaller than that of the gripping portion. And the capping portion, of cylindrical symmetry, has a contact strip and a substantially perpendicular free face, covered with a layer of a polymeric material.

De la sorte, la partie de bouchage peut être portée à l'intérieur de l'ouverture du réceptacle de manière à venir obturer cette ouverture. La bande de contact recouverte du matériau polymère vient alors s'appliquer de façon étanche contre la bordure interne du réceptacle longeant le bord circulaire, tandis que l'épaulement vient s'appliquer contre le bord circulaire. Grâce au matériau polymère, on accroît l'étanchéité au niveau de la bande de contact entre le liège et la bordure interne du réceptacle.In this way, the closing portion can be carried inside the opening of the receptacle so as to close off this opening. The contact strip covered with the polymeric material then seals against the inner edge of the receptacle along the circular edge, while the shoulder is pressed against the circular edge. The polymer material increases the seal at the contact strip between the cork and the inner rim of the receptacle.

Un tel bouchage présente de nombreux avantages, en revanche, il est relativement coûteux, car il nécessite la mise en oeuvre d'un dispositif de bouchage composite.Such closure has many advantages, however, it is relatively expensive because it requires the implementation of a composite closure device.

Aussi, un problème qui se pose et que vise à résoudre la présente invention est de fournir une boîte cylindrique qui soit non seulement étanche mais aussi, qui soit moins coûteuse à réaliser.Also, a problem that arises and that aims to solve the present invention is to provide a cylindrical box which is not only waterproof but also, which is less expensive to achieve.

Dans le but de résoudre ce problème, selon un premier objet, la présente invention propose une boîte cylindrique comprenant un réceptacle et un dispositif de bouchage circulaire en liège destiné à venir boucher ledit réceptacle, ledit réceptacle présentant une ouverture et un bord circulaire entourant ladite ouverture, ledit dispositif de bouchage présentant un épaulement délimitant une partie de préhension et une partie de bouchage, ladite partie de bouchage présentant une bordure circulaire proximale longeant ledit épaulement. Ledit réceptacle comprend un renflement circulaire s'étendant à l'intérieur dudit réceptacle, le long dudit bord circulaire ; et ladite bordure circulaire proximale de ladite partie de bouchage présente une gorge, de manière à ce que ledit renflement circulaire vienne s'engager à l'intérieur de ladite gorge, lorsque ladite partie de bouchage est enfoncée à travers ladite ouverture.In order to solve this problem, according to a first object, the present invention proposes a cylindrical box comprising a receptacle and a circular cork closure device for butchering said receptacle, said receptacle having an opening and a circular edge surrounding said opening, said closure device having a shoulder delimiting a gripping portion and a capping portion, said capping portion having a proximal circular border along said shoulder. Said receptacle comprises a circular bulge extending inside said receptacle, along said circular edge; and said proximal circular rim of said capping portion has a groove, so that said circular bulge engages inside said groove, when said capping portion is squeezed through said opening.

Ainsi, une caractéristique de l'invention réside dans la mise en oeuvre d'un renflement circulaire à l'intérieur du réceptacle et de la réalisation d'une gorge dans la partie de bouchage au niveau de la bordure circulaire proximale jouxtant l'épaulement. De la sorte, lorsque la partie de bouchage du dispositif de bouchage est portée à travers l'ouverture du réceptacle, elle y est portée sensiblement coaxialement au réceptacle, et vient s'appliquer tout d'abord uniformément contre le bord externe du renflement circulaire. Ensuite, en entraînant à force le dispositif de bouchage, la partie de bouchage est entraînée en frottement contre le renflement circulaire et tend à se comprimer radialement, tandis que le renflement circulaire à l'inverse s'élargit sensiblement pour autoriser le passage de la partie de bouchage. En bout de course, le bord circulaire vient en butée contre l'épaulement, tandis que le renflement circulaire se relâche sensiblement à l'intérieur de la gorge et qu'à l'inverse, la partie de bouchage se relâche au-delà du renflement circulaire à l'intérieur du réceptacle. Conséquemment, non seulement le dispositif de bouchage est solidement relié au réceptacle, mais aussi, le bouchage est plus étanche car, la surface de contact entre la partie de bouchage et le réceptacle est supérieure à celle des surfaces de contact entre deux éléments cylindriques des boîtes selon l'art antérieur. Au surplus, il n'est nul besoin de prévoir une couche supplémentaire en matériau polymère, ce qui réduit les coûts de réalisation.Thus, a feature of the invention lies in the implementation of a circular bulge inside the receptacle and the realization of a groove in the capping portion at the proximal circular edge adjacent the shoulder. In this way, when the closing portion of the closure device is carried through the opening of the receptacle, it is carried substantially coaxially with the receptacle, and is applied firstly uniformly against the outer edge of the circular bulge. Then, by forcing the closure device, the sealing portion is driven in friction against the circular bulge and tends to compress radially, while the circular bulge conversely widens substantially to allow the passage of the part. capping. At the end of the stroke, the circular edge abuts against the shoulder, while the circular bulge is released substantially inside the groove and conversely, the closing portion is relaxed beyond the bulge. circular inside the receptacle. Consequently, not only is the closure device securely connected to the receptacle, but also, the closure is more tight because, the contact surface between the capping portion and the receptacle is greater than that of the contact surfaces between two cylindrical elements of the cans. according to the prior art. In addition, there is no need to provide an additional layer of polymer material, which reduces the costs of production.

Selon un mode de mise en oeuvre de l'invention particulièrement avantageux, ladite partie de bouchage présente une bordure circulaire distale libre opposée à ladite bordure circulaire proximale, et ladite bordure distale présente un chanfrein. De la sorte, la bordure distale chanfreinée de la partie de bouchage est apte à venir s'engager dans l'ouverture à l'intérieur du renflement circulaire, et par conséquent, l'opération de rebouchage du réceptacle est plus aisée, comme on l'expliquera plus en détail dans la suite de la description.According to a particularly advantageous embodiment of the invention, said closure portion has a free distal circular border opposite to said proximal circular border, and said distal edge has a chamfer. In this way, the chamfered distal edge of the closure portion is adapted to engage in the opening inside the circular bulge, and therefore, the plugging operation of the receptacle is easier, as it is will be explained in more detail later in the description.

En outre, ladite partie de bouchage présentant une épaisseur de bouchage, tandis que ladite partie de préhension présente une épaisseur de préhension, ladite épaisseur de préhension est supérieure à ladite épaisseur de bouchage. De la sorte, les contraintes que l'on vient exercer sur la partie de préhension pour pouvoir engager la partie de bouchage à l'intérieur du réceptacle, sont mieux absorbées, et ne risque pas de l'endommager.In addition, said capping portion having a capping thickness, while said gripping portion has a gripping thickness, said gripping thickness is greater than said capping thickness. In this way, the stresses that are just exerted on the gripping portion to be able to engage the corking part inside the receptacle, are better absorbed, and does not risk damaging it.

Selon un mode de réalisation de l'invention avantageux, ladite gorge présente un flanc droit s'étendant dans le prolongement dudit épaulement. Ainsi, la gorge vient longer l'épaulement, et lorsque le renflement circulaire vient s'y engager, le bord circulaire du réceptacle est alors maintenu en appui contre l'épaulement. Cela participe également de l'étanchéité du bouchage.According to an advantageous embodiment of the invention, said groove has a straight flank extending in the extension of said shoulder. Thus, the groove comes along the shoulder, and when the circular bulge is engaged, the circular edge of the receptacle is then held in abutment against the shoulder. This also contributes to the sealing of the closure.

Selon un autre mode de réalisation de l'invention, ladite gorge présente un flanc courbé à l'opposé dudit épaulement, présentant un rayon de courbure de flanc Rf. Le rayon de courbure est alors défini par l'intersection d'un plan radial venant couper le flanc courbé, et le flanc de la gorge est alors défini par une portion de surface ellipsoïdale. De la sorte, le flanc courbé forme alors rampe pour le renflement circulaire lorsque la partie de bouchage est engagée dans l'ouverture. Lorsque le renflement circulaire se rétracte, tandis que la partie de bouchage se relâche, le dispositif de bouchage et alors entraîné axialement vers l'intérieur du réceptacle et ainsi, le bord circulaire en appui contre l'épaulement.According to another embodiment of the invention, said groove has a curved flank opposite said shoulder, having a radius of curvature of flank Rf. The radius of curvature is then defined by the intersection of a radial plane coming to cut the curved flank, and the flank of the groove is then defined by an ellipsoidal surface portion. In this way, the curved flank then forms a ramp for the circular bulge when the capping part is engaged in the opening. When the circular bulge retracts, while the closing portion is released, the closure device and then driven axially inwardly of the receptacle and thus the circular edge bearing against the shoulder.

De plus, ledit chanfrein présente un rayon de courbure de chanfrein Rc. Le rayon de courbure de chanfrein est également défini par rapport à un plan radial venant couper le chanfrein. La surface de la bordure circulaire distale libre est alors sensiblement de forme ellipsoïdale également, ce qui permet de faciliter l'emboîtement de la partie de bouchage sur le réceptacle. Préférentiellement, les rayons de courbure de flanc Rf et de Chanfrein Rc sont sensiblement identiques.In addition, said chamfer has a chamfer radius of curvature Rc. The radius of curvature of the chamfer is also defined with respect to a radial plane which cuts the chamfer. The surface of the free distal circular border is then substantially of ellipsoidal shape also, which makes it possible to facilitate the nesting of the capping part on the receptacle. Preferably, the radii of curvature of flank Rf and Chamfer Rc are substantially identical.

Au surplus, de manière particulièrement avantageuse, ladite partie de bouchage définit un cylindre tangentiel de bouchage présentant un rayon de bouchage Rb, tandis que ladite partie de préhension définit un cylindre tangentiel de préhension coaxial audit cylindre tangentiel de bouchage et présentant un rayon de préhension Rp , et la différence desdits rayons de bouchage Rb et de préhension Rp est comprise entre 3 et 5 mm. Une telle valeur relative des rayons de bouchage et des rayons de préhension permet d'opérer le bouchage dans les limites acceptables de déformation du liège de la partie de bouchage.Moreover, in a particularly advantageous manner, said closing portion defines a tangential closure cylinder having a closure radius Rb, while said gripping portion defines a tangential gripping cylinder coaxial with said tangential closure cylinder and having a gripping radius R.sub.A. , and the difference of said plugging radius Rb and gripping Rp is between 3 and 5 mm. Such a relative value of the corking radii and the gripping rays makes it possible to operate the capping within the acceptable limits of deformation of the cork of the corking part.

En outre, ladite partie de bouchage présente une face libre opposée à ladite parie de préhension et délimitée dudit chanfrein par une ligne circulaire présentant un diamètre inférieur au diamètre de fond de ladite gorge. Ainsi, en ajustant les dimensions du renflement circulaire, la bordure circulaire distale libre vient aisément s'engager à l'intérieur du renflement circulaire, tandis que ce dernier demeure sensiblement comprimé à l'intérieur de la gorge de manière à assurer, d'une part une bonne étanchéité du bouchage, mais également une meilleure liaison du dispositif de bouchage et du réceptacle.In addition, said closing portion has a free face opposite to said gripping portion and defined by said chamfer by a circular line having a diameter smaller than the bottom diameter of said groove. Thus, by adjusting the dimensions of the circular bulge, the free distal circular edge easily engages inside the circular bulge, while the latter remains substantially compressed inside the groove so as to ensure, a a good sealing of the closure, but also a better connection of the closure device and the receptacle.

Selon un autre objet, la présente invention propose un dispositif de bouchage circulaire en liège pour une boite cylindrique selon l'une quelconque des caractéristiques énoncées ci-dessus, le dispositif de bouchage présentant un épaulement délimitant une partie de préhension et une partie de bouchage, ladite partie de bouchage présentant une bordure circulaire proximale longeant ledit épaulement ; ladite bordure circulaire proximale de ladite partie de bouchage présentant une gorge.According to another object, the present invention proposes a circular cork closure device for a cylindrical box according to any one of the characteristics stated above, the closure device having a shoulder delimiting a gripping portion and a capping portion, said capping portion having a proximal circular border along said shoulder; said proximal circular edge of said capping portion having a groove.

Par exemple, le dispositif de bouchage conforme à l'invention est réalisé à partir d'un matériau en liège fait de particules de liège agglomérées.For example, the closure device according to the invention is made from a cork material made of agglomerated cork particles.

D'autres particularités et avantages de l'invention ressortiront à la lecture de la description faite ci-après d'un mode de réalisation particulier de l'invention, donné à titre indicatif mais non limitatif, en référence aux dessins annexés sur lesquels :

  • la Figure 1 est une vue schématique en coupe axiale d'un dispositif de bouchage conforme à l'invention; et,
  • la Figure 2 est une vue schématique en coupe axiale d'un élément de la boite cylindrique conforme à l'invention apte à recevoir le dispositif de bouchage conforme à l'invention.
Other features and advantages of the invention will emerge on reading the following description of a particular embodiment of the invention, given by way of indication but not limitation, with reference to the accompanying drawings in which:
  • the Figure 1 is a schematic view in axial section of a closure device according to the invention; and,
  • the Figure 2 is a schematic view in axial section of an element of the cylindrical box according to the invention adapted to receive the closure device according to the invention.

La Figure 1 illustre un dispositif de bouchage 10, tandis que la Figure 2 illustre un réceptacle 12. Comme on l'expliquera dans la suite de la description, le dispositif de bouchage 10 est destiné à coopérer avec le réceptacle 12 pour former une boîte cylindrique conforme à l'invention.The Figure 1 illustrates a closure device 10, while the Figure 2 illustrates a receptacle 12. As will be explained in the following description, the closure device 10 is intended to cooperate with the receptacle 12 to form a cylindrical box according to the invention.

Le dispositif de bouchage 10 est réalisé d'une seule pièce de symétrie circulaire en liège. Il peut être taillé dans une pièce de liège naturel. Avantageusement, le dispositif de bouchage 10 est réalisé dans une pièce de liège agglomérée. Il comprend une partie de préhension 14 et une partie de bouchage 16, séparées l'une de l'autre par un épaulement 18. La partie de bouchage 16 présente une face libre interne 20, tandis qu'à l'opposé, la partie de préhension 14 présente une face libre externe opposée 22.The closure device 10 is made of a single piece of circular symmetry cork. It can be cut in a piece of natural cork. Advantageously, the closure device 10 is made in a piece of agglomerated cork. It comprises a gripping portion 14 and a closing portion 16, separated from each other by a shoulder 18. The closing portion 16 has an inner free face 20, while on the opposite side, the portion of grip 14 has an opposite outer free face 22.

La partie de préhension 14 du dispositif de bouchage 10 présente par exemple, un diamètre compris entre 90 mm et 70 mm, soit un rayon Rp de préhension compris entre 45 mm et 35 mm, tandis que la partie de bouchage 16 présente un diamètre compris entre 82 mm et 64 mm, soit un rayon Rb compris entre 41 mm et 32 mm. On observera que les diamètres et les rayons sont mesurés par rapport à deux cylindres théoriques concentriques, tangents respectivement à la partie de préhension 14 et à la partie de bouchage 16.The gripping portion 14 of the closure device 10 has, for example, a diameter of between 90 mm and 70 mm, ie a gripping radius Rp of between 45 mm and 35 mm, while the closing part 16 has a diameter between 82 mm and 64 mm, a radius Rb between 41 mm and 32 mm. It will be observed that the diameters and the radii are measured with respect to two concentric theoretical cylinders, tangent respectively to the gripping portion 14 and to the closing portion 16.

Il est également prévu de concevoir des dispositifs de bouchage 10 avec des rayons Rp de préhension et Rb de bouchage avec des diamètres situés en dehors des limites mentionnées ci-dessus.It is also intended to design closure devices 10 with Rp rays for gripping and Rb capping with diameters outside the limits mentioned above.

Plus précisément, la différence des rayons de bouchage Rb et de préhension Rp est comprise, par exemple entre 3 mm et 5 mm, de manière à pouvoir assurer à la fois un mode de bouchage étanche et conserver un caractère esthétique à la boîte cylindrique objet de l'invention. Car en effet, le rayon de bouchage Rb correspond en ce cas, sensiblement au rayon externe du réceptacle 12.More precisely, the difference between the plugging radius Rb and the gripping radius Rp is, for example, between 3 mm and 5 mm, so as to be able to ensure both a sealed plugging mode and to preserve an aesthetic character to the cylindrical box object of the invention. For indeed, the capping radius Rb corresponds in this case, substantially to the outer radius of the receptacle 12.

Au surplus, la partie de bouchage 16 présente une épaisseur Eb, comprise par exemple entre 5 mm et 8 mm, tandis que la partie de préhension 18 présente une épaisseur Ep comprise entre 6 mm et 10 mm. On observera que l'épaisseur Ep de la partie de préhension 18 est supérieure à l'épaisseur Eb de la partie de bouchage de manière à obtenir une bonne résistance mécanique de la partie de préhension 18 au regard des efforts qui s'exercent sur elle comme on l'expliquera ci-après.In addition, the capping portion 16 has a thickness Eb, for example between 5 mm and 8 mm, while the gripping portion 18 has a thickness Ep between 6 mm and 10 mm. It will be observed that the thickness Ep of the gripping portion 18 is greater than the thickness Eb of the sealing portion so as to obtain good mechanical strength of the gripping portion 18 with regard to the forces exerted on it as it will be explained below.

La partie de bouchage 16 présente en outre une bordure circulaire proximale 24 et une bordure circulaire distale 26 contiguë. Une gorge 28 est pratiquée dans la bordure circulaire proximale 24. La gorge 28 présente un flanc droit 30 s'étendant dans le prolongement de l'épaulement 18 et à l'opposé, un flanc courbé 32. La bordure circulaire distale 26 présente en outre un chanfrein 34.The closure portion 16 further has a proximal circular border 24 and a contiguous distal circular border 26. A groove 28 is formed in the proximal circular edge 24. The groove 28 has a right sidewall 30 extending in the extension of the shoulder 18 and the opposite a curved sidewall 32. The distal circular edge 26 furthermore a chamfer 34.

Ainsi, la gorge 28 de la bordure circulaire proximale 24 présente, selon une section radiale, un rayon de courbure Rf compris entre 1 mm et 2,5 mm. S'agissant de la bordure circulaire distale 26 chanfreinée, elle présente, toujours selon une section radiale, un rayon de courbure Rc compris entre 1 mm et 2,5 mm également. Par exemple, les rayons de courbure Rf et Rc sont identiques. Leur valeur est par exemple de 1,75 mm.Thus, the groove 28 of the proximal circular edge 24 has, in a radial section, a radius of curvature Rf between 1 mm and 2.5 mm. With regard to the chamfered distal circular edge 26, it has, always in a radial section, a radius of curvature Rc of between 1 mm and 2.5 mm also. For example, the radii of curvature Rf and Rc are identical. Their value is for example 1.75 mm.

On se référera à présent à la Figure 2 montrant le réceptacle 12 avec lequel est apte à coopérer le dispositif de bouchage 10.We will now refer to the Figure 2 showing the receptacle 12 with which the closure device 10 is able to cooperate.

Le réceptacle 12 est réalisé dans un matériau à base cellulosique par exemple. Il est néanmoins rigide. Le matériau présente par exemple, une épaisseur comprise entre 1 mm et 2,5 mm. Le réceptacle 12 est de symétrie cylindrique à courbe directrice circulaire. Il présente un bord circulaire 36 délimitant une ouverture 38, laquelle débouche à l'intérieur 40 du réceptacle 12. Celui-ci présente un fond 41. De plus, le réceptacle 12 comprend un renflement circulaire supérieur 42 libre, réalisé selon la technique du bord roulé. Le renflement circulaire supérieur 42 s'étend vers l'intérieur de l'ouverture 38. Par exemple, il présente une épaisseur radiale comprise entre 3 mm et 5 mm. Avantageusement, l'épaisseur radiale du renflement circulaire 42 est de 4 mm. Préférentiellement, selon une coupe radiale, le renflement circulaire supérieur 42 présente un rayon sensiblement identique au rayon de courbure Rf de la gorge 28.The receptacle 12 is made of a cellulosic material for example. It is nonetheless rigid. The material has, for example, a thickness of between 1 mm and 2.5 mm. The receptacle 12 has a cylindrical symmetry with a circular guide curve. It has a circular edge 36 defining an opening 38, which opens into the interior 40 of the receptacle 12. The latter has a bottom 41. In addition, the receptacle 12 comprises an upper circular bulge 42 free, made according to the technique of the edge rolled. The upper circular bulge 42 extends inwardly of the opening 38. For example, it has a radial thickness of between 3 mm and 5 mm. Advantageously, the radial thickness of the circular bulge 42 is 4 mm. Preferably, in a radial section, the upper circular bulge 42 has a radius substantially identical to the radius of curvature Rf of the groove 28.

On observera que le diamètre extérieur du réceptacle 12 est sensiblement égal à deux fois le rayon Rp de la partie de préhension 18 du dispositif de bouchage 10. En outre, le réceptacle 12 présente un renflement circulaire inférieur 44 s'étendant vers l'intérieur 40 du réceptacle 12 et sur lequel vient s'appuyer le fond 41.It will be observed that the outer diameter of the receptacle 12 is substantially equal to twice the radius Rp of the gripping portion 18 of the closure device 10. In addition, the receptacle 12 has a lower circular bulge 44 extending inwardly 40 of the receptacle 12 and on which bears the bottom 41.

Ainsi, en se référant aux Figures 1 et 2, on décrira la coopération du dispositif de bouchage 10 et du réceptacle 12.Thus, by referring to Figures 1 and 2 , we will describe the cooperation of the closure device 10 and the receptacle 12.

En approchant coaxialement le dispositif de bouchage 10 du réceptacle 12 on vient tout d'abord introduire la partie de bouchage 16 à travers l'ouverture 38 et de la sorte, porter le chanfrein 34 de la bordure circulaire distale 26 en appui contre le renflement circulaire supérieur 42. Plus précisément, le chanfrein 34 vient en contact sur la partie supérieure du renflement circulaire supérieur 42. Au point de contact, la tangente commune au renflement circulaire supérieur 42 et au chanfrein 34 est sensiblement inclinée par rapport à l'axe de symétrie du dispositif de bouchage 10 lequel est commun à celui du réceptacle 12. L'inclinaison de la tangente est par exemple de 45°.By coaxially approaching the closure device 10 of the receptacle 12, the capping portion 16 is firstly introduced through the opening 38 and in this way, the chamfer 34 of the distal circular edge 26 bears against the circular bulge. 42. More precisely, the chamfer 34 comes into contact on the upper part of the upper circular bulge 42. At the point of contact, the tangent common to the upper circular bulge 42 and the chamfer 34 is substantially inclined with respect to the axis of symmetry. of the closure device 10 which is common to that of the receptacle 12. The inclination of the tangent is for example 45 °.

Le dispositif de bouchage 10 est alors entraîné à force selon l'axe de symétrie précité vers le réceptacle 12. Partant, le chanfrein 34 et la partie supérieure du renflement circulaire supérieur 42 forme rampe l'un par rapport à l'autre, et tandis que la bordure circulaire distale 26 tend à provoquer l'élargissement radial de l'ouverture 38 en déformant sensiblement le renflement circulaire supérieur 42, le même renflement circulaire supérieur 42 tend à venir comprimer radialement la bordure circulaire distale 26 elle-même. Compte tenu de sa nature, le liège, cette contraction radiale est rendue possible. Poursuivant l'enfoncement du dispositif de bouchage 10 à l'intérieur 40 du réceptacle 12, lorsque le flanc courbé 32 vient alors en contact avec la partie inférieure du renflement circulaire supérieur 42, la bordure circulaire distale 26 à l'inverse se décontracte radialement tandis que le renflement circulaire supérieur 42 se relâche et resserre ainsi l'ouverture 38. Ces deux effets concomitants, tendent à provoquer l'entraînement plus encore du dispositif de bouchage 10 vers l'intérieur 40 du réceptacle 12, jusqu'à ce que l'épaulement 18 vienne en butée contre le bord circulaire 36. Le renflement circulaire supérieur 42 se relâche alors à l'intérieur de la gorge 28. Le dispositif de bouchage 10 est alors totalement solidaire du réceptacle 12. Il en est d'ailleurs prisonnier dans la limite des efforts à exercer sur le dispositif de bouchage 10 pour l'en désolidariser. On observera que ces efforts sont supérieurs à ceux qu'il convient de mettre en oeuvre pour désolidariser les dispositifs de bouchage classiques où la partie de bouchage est purement cylindrique.The closure device 10 is then force-driven along the aforementioned axis of symmetry towards the receptacle 12. Therefore, the chamfer 34 and the upper part of the upper circular bulge 42 form crawl with respect to each other, and while that the distal circular edge 26 tends to cause the radial widening of the opening 38 by substantially deforming the upper circular bulge 42, the same upper circular bulge 42 tends to compress radially the distal circular edge 26 itself. Given its nature, cork, this radial contraction is made possible. Continuing the depression of the closure device 10 inside 40 of the receptacle 12, when the curved flank 32 then comes into contact with the lower part of the upper circular bulge 42, the distal circular edge 26 conversely relaxes radially while that the upper circular bulge 42 is loosened and thus tightens the opening 38. These two concomitant effects, tend to cause the drive of the closure device 10 to be further inwardly 40 of the receptacle 12, until the shoulder 18 comes into abutment against the circular edge 36. The upper circular bulge 42 then relaxes inside the groove 28. The closure device 10 is then completely integral with the receptacle 12. It is also a prisoner in the limit of efforts to exert on the closure device 10 to separate it. It will be observed that these forces are greater than those which must be implemented to separate the conventional plugging devices where the plugging portion is purely cylindrical.

Compte tenu des surfaces de contact entre le dispositif de bouchage 10 et le réceptacle 12 qui s'étendent du point de contact entre le bord circulaire 36 et l'épaulement 18 jusqu'à l'intérieur 40 du réceptacle 12, du point de contact entre le flanc courbé 32 et la partie inférieure du renflement circulaire supérieur 42, on obtient une bonne étanchéité de l'intérieur 40 de la boîte vis-à-vis de l'extérieur.Given the contact surfaces between the closure device 10 and the receptacle 12 which extend from the point of contact between the circular edge 36 and the shoulder 18 to the inside 40 of the receptacle 12, the point of contact between the curved flank 32 and the lower part of the upper circular bulge 42, a good seal is obtained from the inside 40 of the box vis-à-vis the outside.

Au surplus, grâce au renflement circulaire inférieur 44, de même nature que le renflement circulaire supérieur 42, on peut venir rapporter le dispositif de bouchage 10 contre la paroi de fond 41 et l'y solidariser. Le dispositif de bouchage 10 demeure alors imperdable lors de l'utilisation du réceptacle 12.Moreover, thanks to the lower circular bulge 44, of the same nature as the upper circular bulge 42, we can come bring the closure device 10 against the bottom wall 41 and join it there. The closure device 10 then remains captive when using the receptacle 12.
