Description

La présente invention a pour objet un dispositif en deux pièces agencé pour assurer l'obturation étanche des flacons, bocaux et autres récipients similaires tout en permettant, à travers un évent de dégazage fonctionnant à la manière d'un clapet de surpression, l'échappement automatique des gaz engendrés par le contenu du récipient considéré.The present invention relates to a two-piece device arranged to ensure the tight sealing of the bottles, jars and other similar containers while allowing, through a degassing vent operating in the manner of a pressure relief valve, the exhaust automatic gas generated by the contents of the container in question.

Le dispositif suivant l'invention comprend en premier lieu un obturateur qui est propre à s'engager dans le débouché du récipient en vue de le fermer de manière étanche et dont la partie centrale est découpée d'une ouverture bordée d'une lèvre continue tournée vers le haut. A cette première pièce est associée une cape qui comporte, outre des moyens aptes à assurer sa retenue sur le récipient et celle de l'obturateur qu'elle coiffe, une lèvre centrale continue qui est tournée vers le bas pour coopérer de manière étanche avec la lèvre de l'obturateur, la partie centrale du fond de la cape qui est soumise à la pression interne du récipient à travers l'ouverture de l'obturateur étant apte à se déformer élastiquement pour faire momentanément cesser l'étanchéité au niveau des deux lévres en contact en permettant de la sorte l'échappement des gaz en surpression.The device according to the invention comprises in the first place a shutter which is capable of engaging in the opening of the container in order to close it in a sealed manner and the central part of which is cut out with an opening bordered by a continuous turned lip to the top. With this first part is associated a cape which comprises, in addition to means capable of ensuring its retention on the container and that of the shutter which it covers, a continuous central lip which is turned downwards to cooperate in leaktight manner with the obturator lip, the central part of the bottom of the cape which is subjected to the internal pressure of the container through the opening of the obturator being able to deform elastically to temporarily stop sealing at the two lips in contact, thereby allowing the overpressure gases to escape.

Il est bien entendu avantageux de réaliser l'obturateur en une matière synthétique relativement souple et déformable, alors que la cape est établie en une matière synthétique plus rigide.It is of course advantageous to produce the shutter in a relatively flexible and deformable synthetic material, while the cap is established in a more rigid synthetic material.

Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer :

  • Fig. 1 est une coupe axiale à échelle agrandie, montrant en superposition, préalablement à leur assemblage, les deux piè­ces constitutives d'un dispositif d'obturation suivant l'invention et la partie supérieure du récipient correspon­dant.
  • Fig. 2 reproduit fig. 1 après assemblage des trois éléments au moment du bouchage du récipient.
  • Fig. 3 est une coupe analogue à celle de fig. 2, illustrant la déformation de la cape lors du dégazage.
The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing:
  • Fig. 1 is an axial section on an enlarged scale, showing in superposition, prior to their assembly, the two constituent parts of a closure device according to the invention and the upper part of the corresponding container.
  • Fig. 2 reproduced fig. 1 after the three elements have been assembled when the container is capped.
  • Fig. 3 is a section similar to that of FIG. 2, illustrating the deformation of the cap during degassing.

Le dispositif d'obturation suivant l'invention tel qu'il apparaît en fig. 1 comprend en premier lieu un obturateur 1 à profil circulaire, réalisé en une matière synthétique relativement souple et déformable. Cet obturateur 1 comporte, au voisinage de son bord extérieur, une partie 10 en forme de cuvette annulaire ouverte vers le haut, qui se raccorde d'une part avec un rebord extérieur 11 ouvert en direction du bas, d'autre part avec une cloison annulaire 12 à profil tronconique ou­vert en direction du bas. Cette cloison 12 est elle-même réunie par une partie supérieure arquée 13 à un plateau central 14 qui est solidai­re d'une lèvre cylindrique 15 tournée axialement vers le haut. On observera que le plateau central 14 présente une série d'ouvertures ménagées entre des bras radiaux 16.The closure device according to the invention as it appears in FIG. 1 comprises firstly a shutter 1 with a circular profile, made of a relatively flexible and deformable synthetic material. This shutter 1 comprises, in the vicinity of its outer edge, a part 10 in the form of an annular bowl open upwards, which is connected on the one hand with an external rim 11 open in the direction of the bottom, on the other hand with a partition annular 12 with frustoconical profile open towards the bottom. This partition 12 is itself joined by an arcuate upper part 13 to a central plate 14 which is integral with a cylindrical lip 15 turned axially upwards. It will be observed that the central plate 14 has a series of openings formed between radial arms 16.

Le dispositif comprend également une cape 2 en forme de couvercle, éta­blie en une matière synthétique rigide qui n'est susceptible de se dé­former élastiquement que moyennant l'application d'un effort relative­ment important. La jupe cylindrique de cette cape 2 est divisée par une zone annulaire amincie 20 en deux partie superposées. La partie inférieure 21 est destinée à former ceinture déchirable de garantie et elle comporte un bourrelet interne de retenue 22, tandis que la partie supérieure 23 présente elle-même une saillie annulaire interne 24. Le fond supérieur 25 de la cape est établi à un profil très légèrement concave ouvert à l'opposé de la jupe, et il est solidaire dans sa partie centrale d'une lèvre cylindrique axiale 26 tournée vers le bas. Il convient de remarquer que les lévres 15 et 26, destinées à coopérer l'une avec l'autre, comportent une face droite et une face oblique. La face oblique, référencée 17, de la lèvre 15 est disposée à l'interieur alors que la face oblique 27 de la lèvre 26 est située à l'extérieur. De plus, ces deux faces obliques 17 et 27 présentent des angles légèrement différent.The device also comprises a cape 2 in the form of a cover, made of a rigid synthetic material which is capable of deforming elastically only with the application of a relatively large force. The cylindrical skirt of this cape 2 is divided by a thinned annular zone 20 into two superimposed parts. The lower part 21 is intended to form a tear-away guarantee belt and it has an internal retaining bead 22, while the upper part 23 itself has an internal annular projection 24. The upper bottom 25 of the cap is established in a profile very slightly concave open opposite the skirt, and it is integral in its central part with an axial cylindrical lip 26 facing downwards. It should be noted that the lips 15 and 26, intended to cooperate with each other, have a straight face and an oblique face. The oblique face, referenced 17, of the lip 15 is arranged inside while the oblique face 27 of the lip 26 is located outside. In addition, these two oblique faces 17 and 27 have slightly different angles.

Le dispositif ainsi agencé est destiné à assurer l'obturation d'un pot en verre 3 dont l'ouverture 30 est bordée à son sommet par un rebord 31 tourné vers l'extérieur.The device thus arranged is intended to close off a glass jar 3, the opening 30 of which is bordered at its top by a rim 31 facing outwards.

Lors du bouchage réalisé après remlplissage du pot 3 ainsi agencé, l'ob­turateur 1 est engagé dans l'ouverture 30, la cuvette 10 venant s'adap­ter étroitement dans le débouché supérieur 32 de ladite ouverture en assurant un contact étanche. Comme illustré en fig. 2, le rebord 11 vient lui-même prendre appui contre la face supérieur plane du rebord 31. Pour opérer le bouchage complet, il suffit de mettre en place la ca­pe 2 ; le bourrelet 22 de la ceinture de garantie 21 vient s'encliqueter au-dessous du rebord 31 en assurant la retenue de ladite cape et de l'obturateur 1 coiffé par celle-ci, étant observé que le bord libre de cet obturateur 1 vient lui-même se clipser au-dessus de la saillie annu­laire 24. Par ailleurs, la lèvre 26 de la cape 2 s'engage à force à l'intérieur de la lèvre 15 de l'obturateur qui est ainsi déformée ; on obtient ainsi un contact étanche qui opère en quelque sorte le bouchage du plateau central ajouré 14 de l'obturateur.During the capping carried out after filling the pot 3 thus arranged, the shutter 1 is engaged in the opening 30, the bowl 10 coming to closely fit in the upper outlet 32 of said opening while ensuring a tight contact. As illustrated in fig. 2, the rim 11 itself comes to bear against the flat upper face of the rim 31. To operate the complete closure, it suffices to put on the cap 2; the bead 22 of the guarantee belt 21 snaps below the rim 31 while ensuring the retention of said cap and of the shutter 1 capped by the latter, it being observed that the free edge of this shutter 1 comes to it -Even clip on above the annular projection 24. Furthermore, the lip 26 of the cap 2 engages by force inside the lip 15 of the shutter which is thus deformed; a tight contact is thus obtained which in a way operates the plugging of the perforated central plate 14 of the shutter.

On peut remarquer que la coopération des lèvres cylindriques 15 et 26 renforce l'application élastique de la cuvette 10 contre le débouché 32 de l'ouverture 30 du pot 3, de telle sorte que l'étanchéité à ce niveau est obtenue même dans le cas où le débouché précité serait mal calibré dans ses dimensions comme dans son profil. En même temps, la déformation qui résulte de la coopération susvisée provoque, outre l'abaissement du plateau central ajouré 14, le raidissement de celui-ci qui se comporte alors comme une paroi pratiquement rigide.It can be noted that the cooperation of the cylindrical lips 15 and 26 strengthens the elastic application of the bowl 10 against the outlet 32 of the opening 30 of the pot 3, so that the seal at this level is obtained even in the case where the aforementioned outlet would be badly calibrated in its dimensions as in its profile. At the same time, the deformation which results from the abovementioned cooperation causes, in addition to the lowering of the perforated central plate 14, the stiffening of the latter which then behaves like a practically rigid wall.

Si le contenu du pot 3 engendre à un moment donné une surprssion inter­ne, cette dernière contre la partie centrale du fond 25 définie par la lèvre 26, si bien que lorsque l'effet de poussée ainsi exercé dépasse un certain seuil, c'est l'ensemble du fond 25 qui se dé­forme momentanément vers le haut (fig. 3), ledit fond 25 perdant son profil concave pour affecter un profil pratiquement plan. Cette deforma­tion de la cape 2 fait cesser l'étanchéité du contact des deux lèvres 26 et 15, de telle sorte que les gaz sous pression enclos dans la partie supérieure du pot 3 peuvent s'échapper à l'extérieur en traversant tout d'abord l'espace ménagé entre les deux lèvres précitées, puis des rainu­res 18, 28 et 29 pratiquées à cet effet respectivement dans la face su­périeure du rebord annulaire 11 de l'obturateur 1, dans la saillie annu­laire 24 et dans le bourrelet de retenue 22.If the content of the pot 3 generates an internal overload at a given moment, the latter against the central part of the bottom 25 defined by the lip 26, so that when the pushing effect thus exerted exceeds a certain threshold, it is l 'set of the bottom 25 which momentarily deforms upwards (fig. 3), said bottom 25 losing its concave profile to affect a practically flat profile. This deformation of the cap 2 causes the sealing of the contact between the two lips 26 and 15 to cease, so that the pressurized gases enclosed in the upper part of the pot 3 can escape to the outside by first passing through the space provided between the two aforementioned lips, then grooves 18, 28 and 29 made for this purpose respectively in the upper face of the annular rim 11 of the shutter 1, in the annular projection 24 and in the retaining bead 22.

Il va de soi que cet échappement est instantané et que le fond 25 de la cape 2 revient, de manière pratiquement immédiate sous l'effet de son élasticité, à son profil concave antérieure en assurant à nouveau l'étanchéité au niveau des lèvres 26 et 15. L'échappement est suscepti­ble de se répéter autant de fois que nécessaire pour permettre l'évacua­tion plus ou moins périodique des gaz engendrés par le produit renfermé par le pot 3. On observera que la déformation momentanée du fond 25 peut intervenir même dans le cas où les pots fermés se trouveraient empilés les uns sur les autres, par suite du profil concave dudit fond et du profil le plus souvent concave du fond des pots de ce type.It goes without saying that this escapement is instantaneous and that the bottom 25 of the cap 2 returns, almost immediately under the effect of its elasticity, to its anterior concave profile while again ensuring the seal at the lips 26 and 15. The exhaust is likely to repeat itself as many times as necessary to allow the more or less periodic evacuation of the gases generated by the product contained in the pot 3. It will be observed that the momentary deformation of the bottom 25 can intervene even in the case where the closed pots are stacked on top of each other, as a result of the concave profile of said bottom and the most often concave profile of the bottom of pots of this type.

Bien évidemment, la ceinture de garantie 21, qui n'est au surplus nulle­ment obligatoire, joue le rôle habituel, à savoir qu'elle garantit par sa présence le contenu original du pot 3 jusqu'au moment de la première utilisation de celui-ci. Une fois cette ceinture 21 éliminée par déchirage au niveau de la zone amincie 20, la cape 2 n'est plus retenue sur le pot 3, si bien qu'elle peut être otée par l'utilisateur, étant observé que l'obturateur 1 est enlevé en même temps du fait que le clip­sage du bord terminal du rebord 11 au-dessus de la saillie annulaire 24 assure la solidarisation des deux pièces 1 et 2 du dispositif de bouchage.Obviously, the guarantee belt 21, which is in no way obligatory, plays the usual role, namely that it guarantees by its presence the original content of the pot 3 until the time of its first use. . Once this belt 21 has been removed by tearing at the thinned zone 20, the cap 2 is no longer retained on the pot 3, so that it can be removed by the user, it being observed that the shutter 1 is removed at the same time because the clipping of the end edge of the rim 11 above the annular projection 24 ensures the joining of the two parts 1 and 2 of the closure device.

On conçoit que la mise en place de ce dispositif peut être effectuée en deux phases successives comme on l'a décrit plus haut, ou en une seule phase, les deux pièces 1 et 2 étant alors assemblés l'une à l'autre soit par clipsage au-dessus de la saillie 24, soit par simple engagement du bord de l'obturateur 1 dans le logement annulaire déterminé entre le bourrelet 22 et ladite saillie 24.It is understood that the installation of this device can be carried out in two successive phases as described above, or in a single phase, the two parts 1 and 2 then being assembled to each other either by clipping above the projection 24, either by simple engagement of the edge of the shutter 1 in the annular housing determined between the bead 22 and said projection 24.
