Description

La présente invention concerne l'obturation de récipients au moyen d'un dispositif assurant un évent.The present invention relates to closing containers by means of a device ensuring a vent.

L'invention concerne plus particulièrement un dispositif d'obturation de récipients qui, une fois convenablement mis en place sur le récipient à obturer, permet d'éviter pratiquement toute fuite de liquide ou de matieres solides dudit récipient et également d'assurer l'élimination automatique des gaz en surpression existants ou formés dans ce même récipient.The invention relates more particularly to a container closure device which, once suitably placed on the container to be closed, makes it possible to practically avoid any leakage of liquid or solid matter from said container and also to ensure elimination automatic overpressure gases existing or formed in the same container.

Bien que l'invention ne soit pas limitée à un type de récipient particulier, ni à un domaine d'application plus qu'à d'autres, il paraît plus simple pour l'exposé qui va suivre de décrire l'invention, et la technique antérieure dont elle se démarque, en référence à une application particulière et à un récipient de type flacon à goulot fileté et bouchon vissé. Il est clair que, l'invention ne s'appliquant pas seulement à ce cas, ce qui est dit dans la suite peut être transposé mutatis mutandis à d'autres catégories de récipients et/ou d'applications, sans qu'on sorte pour autant du cadre de l'invention revendiquée.Although the invention is not limited to a particular type of container, nor to a field of application more than others, it seems simpler for the description which follows to describe the invention, and the prior art from which it stands out, with reference to a particular application and to a container of the bottle type with a threaded neck and a screw cap. It is clear that, the invention not applying only to this case, what is said hereinafter can be transposed mutatis mutandis to other categories of containers and / or applications, without going out for as much of the scope of the claimed invention.

Le domaine d'application ainsi retenu à titre illustratif dans ce qui suit est le bouchage de flacons renfermant un produit de nettoyage liquide contenant un hypochlorite, notamment de l'hypochlorite de sodium ayant un titre chlorométrique élevé.The field of application thus retained by way of illustration in what follows is the closure of bottles containing a liquid cleaning product containing a hypochlorite, in particular sodium hypochlorite having a high chlorometric titer.

Il est connu que les compositions liquides de nettoyage contenant de l'hypochlorite ayant un titre chlorométrique élevé libèrent en cours de stockage de l'oxygène gazeux produit par la décomposition lente de l'hypochlorite.It is known that liquid cleaning compositions containing hypochlorite having a high chlorometric titer release during storage oxygen gas produced by the slow decomposition of hypochlorite.

Si le récipient contenant ces compositions a un bouchage parfaitement étanche aux gaz, la surpression des gaz peut faire gonfler le récipient et le rendre fuyard.If the container containing these compositions has a perfectly gas-tight stopper, the overpressure of the gases can cause the container to swell and make it leaky.

Il existe actuellement des systèmes de bouchage agencés de façon à procurer un effet de soupape dont le déclenchement est automatique à partir d'une surpression plus ou moins prédéterminée de gaz dans le récipient. Ces systèmes, dont le fonctionnement repose sur un déplacement par déformation d'une pièce d'étanchéification circulaire --ce déplacement étant permis par un profil approprié du fond du bouchon dans lequel cette pièce circulaire s'insère --, ont toutefois pour inconvénients :

  • - qu'ils laissent s'échapper du récipient, non seulement le gaz en surpression, mais aussi du mélange liquide-gaz sous forme d'une mousse qui suinte et forme des dépôts cristallisés autour du système de bouchage ; et
  • - qu'ils ne peuvent fonctionner que si leur serrage sur le col fileté du récipient demeure suffisamment lâche pour laisser subsister un degré de liberté pour la pièce d'étanchéification circulaire, mais n'est cependant pas trop lâche pour que n'apparaisse pas une absence totale d'étanchéité aux liquides.
There are currently closure systems arranged so as to provide a valve effect the triggering of which is automatic from a more or less predetermined overpressure of gas in the container. These systems, the operation of which is based on a displacement by deformation of a circular sealing part - this displacement being permitted by an appropriate profile of the bottom of the plug in which this circular part is inserted - have the disadvantages, however:
  • - that they let escape from the container, not only the gas in overpressure, but also of the liquid-gas mixture in the form of a foam which seeps and forms crystallized deposits around the closure system; and
  • - They can only work if their tightening on the threaded neck of the container remains sufficiently loose to allow a degree of freedom to remain for the circular sealing part, but is not, however, too loose so that a total lack of liquid tightness.

On a maintenant trouvé, de façon inattendue, qu'on peut apporter une solution à ces problèmes, et obtenir d'autres avantages qui apparaîtront dans la suite de la présente description, au moyen d'un dispositif pratique et simple d'obturation avec évent.We have now unexpectedly found that it is possible to provide a solution to these problems, and to obtain other advantages which will appear in the remainder of this description, by means of a practical and simple device for closing with a vent. .

L'invention a pour objet un dispositif d'obturation formant valve pour l'élimination automatique des gaz en surpression dans un récipient muni d'un tel dispositif. Ce dispositif ne laisse pratiquement pas fuir de liquide ou de matières solides, dans des conditions normales d'utilisation, et ne nécessite pas d'être ajusté à un stade incomplet de serrage.The subject of the invention is a closure device forming a valve for the automatic elimination of overpressure gases in a container fitted with such a device. This device practically does not leak liquid or solid matter, under normal conditions of use, and does not need to be adjusted at an incomplete tightening stage.

Ce dispositif est, dans son principe, tel que décrit dans les figures 1 et 2 de la planche unique de dessins ci-annexée.

  • La figure 1 représente une vue de côté en coupe longitudinale schématique de la partie supérieure d'un flacon à goulot fileté muni d'une forme de réalisation d'un dispositif selon l'invention.
  • La figure 2 représente une vue de dessus, en coupe partielle schématique selon la ligne A-A, du dispositif selon l'invention correspondant à la même forme de réalisation.
This device is, in principle, as described in Figures 1 and 2 of the single sheet of drawings attached.
  • Figure 1 shows a schematic longitudinal sectional side view of the upper part of a threaded neck bottle provided with an embodiment of a device according to the invention.
  • 2 shows a top view, in schematic partial section along the line AA, of the device according to the invention corresponding to the same embodiment.

De manière générale, ce dispositif comprend essentiellement :

  • - une pièce d'obturation 1 ou bouchon à fond plat,
  • - un secteur de disque de matière 2 venant s'insérer sur le fond plat du bouchon et tel que le secteur de disque soit supérieur à la moitié du secteur circulaire de même diamètre, et
  • - une pièce 3 comportant une couronne circulaire et exerçant, lorsque le dispositif est en position d'obturation de l'orifice du récipient, une pression d'écrasement sur la couronne circulaire du secteur de disque élastique correspondant à cette couronne circulaire, tandis que la partie dudit secteur de disque élastique, située à l'intérieur de cette couronne circulaire, demeure non écrasée

ou écrasée seulement partiellement et conserve une élasticité propre pour fléchir sous l'effet d'une surpression de gaz et revenir ensuite à sa position de bouchage étanche normal.In general, this device essentially comprises:
  • - a sealing piece 1 or flat-bottomed plug,
  • a disc sector of material 2 which is inserted on the flat bottom of the cap and such that the disc sector is greater than half of the circular sector of the same diameter, and
  • a part 3 comprising a circular crown and exerting, when the device is in the closed position of the container orifice, a crushing pressure on the circular crown of the sector of elastic disc corresponding to this circular crown, while the part of said elastic disc sector, located inside this circular crown, remains not crushed

or only partially crushed and retains its own elasticity to flex under the effect of an overpressure of gas and then return to its position normal sealing closure.

Selon une forme de réalisation, la pièce 3 susdite peut être constituée directement par la couronne circulaire surélevée de l'orifice, tel que par exemple un goulot du récipient concerné, ce qui ramène donc à deux le nombre des pièces du dispositif selon l'invention.According to one embodiment, the above-mentioned part 3 can be formed directly by the raised circular crown of the orifice, such as for example a neck of the container concerned, which therefore reduces the number of parts of the device according to the invention to two .

En variante, la pièce 3 peut être (voir figure 1) une pièce qui assure, de manière classique, une réduction du diamètre d'ouverture de l'orifice du récipient et qui, venant s'insérer en force dans ledit orifice et ayant, sur le pourtour de sa surface supérieure, une zone (couronne circulaire) surélevée, exerce, lorsque le dispositif est en position d'obturation de l'orifice du récipient, une pression d'écrasement sur la couronne circulaire du secteur de disque élastique correspondant à cette couronne circulaire surélevée, tandis que la partie dudit secteur de disque élastique, située à l'intérieur de cette couronne circulaire, se comporte comme indiqué ci-dessus.As a variant, the part 3 can be (see FIG. 1) a part which ensures, in a conventional manner, a reduction in the opening diameter of the orifice of the container and which which, being inserted by force into said orifice and having, on the periphery of its upper surface, a raised zone (circular crown), exerts, when the device is in the closed position of the container orifice, a crushing pressure on the circular crown of the elastic disc sector corresponding to this raised circular crown, while the part of said elastic disc sector, located inside this circular crown, behaves as indicated above.

Ainsi que le montrent les figures ci-jointes, la pièce 2 est constituée par un secteur de disque dont la surface est supérieure à celle du demi-secteur circulaire de même diamètre, de façon à recouvrir l'orifice du récipient sur lequel le dispositif trouve sa place ou l'orifice 4 de la pièce 3.As shown in the attached figures, the part 2 is constituted by a disk sector whose surface is greater than that of the circular half-sector of the same diameter, so as to cover the orifice of the container on which the device finds its place or the orifice 4 of the part 3.

La ligne de bord 5 de la pièce 2 peut se situer à un niveau, a priori, quelconque, dans la limite indiquée ci-dessus ; de plus, cette ligne de bord peut avoir un profil quelconque dans sa partie intérieure entre les deux extrémités de la ligne de pourtour circulaire. La ligne de bord susdite est, de préférence, constituée par un segment de droite et il est apparu avantageux qu'elle se situe de façon à être pratiquement tangente au diamètre intérieur de l'orifice du récipient concerné ou de la partie surélevée de la pièce 3.The edge line 5 of the part 2 can be located at any level, a priori, within the limit indicated above; moreover, this edge line can have any profile in its inner part between the two ends of the circular perimeter line. The abovementioned edge line is preferably constituted by a straight line and it has appeared advantageous that it is situated so as to be practically tangent to the internal diameter of the orifice of the container concerned or of the raised part of the part. 3.

Bien entendu, il est également possible, conformément à l'invention, de munir la pièce 2 de plusieurs lignes de bord telles que celle décrite ci-dessus et portant sur les schémas la référence 5 ; à titre d'exemples non limitatifs on peut ainsi réaliser une pièce 2 dans laquelle deux lignes de bord sont présentes, dans des dispositions respectives quelconques et, de préférence, parallèles l'une à l'autre et diamétralement opposées, ou bien la pièce 2 peut recevoir, par des découpes ou une fabrication appropriées, trois lignes de bord, dont chacune répond à la définition donnée plus haut pour la ligne de bord 5 et qui sont, de préférence, disposées de façon à faire entre elles un angle de 120°, prises deux à deux.Of course, it is also possible, in accordance with the invention, to provide the part 2 with several edge lines such as that described above and bearing on the diagrams the reference 5; by way of nonlimiting examples, it is thus possible to produce a part 2 in which two edge lines are present, in any respective arrangements and, preferably, parallel to one another and diametrically opposite, or else part 2 may receive, by appropriate cutouts or manufacture, three edge lines, each of which meets the definition given above for edge line 5 and which are preferably arranged so as to form an angle of 120 ° between them , taken two by two.

L'homme du métier est à même de choisir à convenance les matériaux constituant chacune des pièces susdites. A titre d'exemples non limitatifs, la pièce 1 et la pièce 3 ou la partie du récipient constituant la couronne circulaire entourant l'orifice peuvent être choisies indépendamment l'une de l'autre, parmi des matières plastiques rigides ou semi-rigides, telles que du polyéthylène, du polypropylène ou autres, de l'ébonite, des matériaux métalliques ou composites ; la pièce 2 peut être constituée par tout matériau approprié ayant une élasticité propre, tel que par exemple du polyéthylène expansé, du caoutchouc naturel ou synthétique, du liège et autres. L'élasticité du matériau de la pièce 2 doit être telle que, sous les surpressions de gaz auxquelles on souhaite qu'il y ait évacuation substantielle du gaz en surpression sans fuite notable du contenu liquide ou solide du récipient muni du dispositif selon l'invention, la pièce 2 de ce dernier subisse un écrasement partiel permettant tout juste de dégager le long de la ligne de bord susdite un orifice secondaire ou zone d'échappement des gaz.A person skilled in the art is able to choose the materials constituting each of the aforementioned parts at will. By way of nonlimiting examples, the part 1 and the part 3 or the part of the container constituting the circular crown surrounding the orifice can be chosen independently of one another, from rigid or semi-rigid plastics, such as polyethylene, polypropylene or the like, ebonite, metallic or composite materials; the part 2 can be constituted by any suitable material having its own elasticity, such as for example expanded polyethylene, natural or synthetic rubber, cork and the like. The elasticity of the material of the part 2 must be such that, under the gas overpressures at which it is desired that there is a substantial evacuation of the gas under pressure without significant leakage of the liquid or solid content of the container provided with the device according to the invention , part 2 of the latter undergoes a partial crushing just allowing to release along the above edge line a secondary orifice or gas exhaust zone.

Les caractéristiques dimensionnelles des différents éléments du dispositif peuvent également être établies à convenance par l'homme du métier qui a simplement comme tâches de se fixer ou de prendre en compte des contraintes techniques, dimensionnelles ou autres, et de procéder à des essais de routine, nécessaires à la mise au point d'un prototype dans chaque cas d'application spécifique. Toutefois, une donnée commune à tous les cas d'applications est que, d'une part, la compressibilité du matériau de la pièce 2 et, d'autre part, le niveau de la couronne circulaire de la pièce 3 soient tels que, en position d'utilisation, la compression de la pièce 2 sous l'effet d'une surpression de gaz puisse dégager, au niveau de la ligne de bord 5 une zone d'échappement pour les gaz du récipient responsables de cette surpression.The dimensional characteristics of the various elements of the device can also be established at will by the person skilled in the art, who simply has the tasks of fixing or taking into account technical, dimensional or other constraints, and of carrying out routine tests, necessary for the development of a prototype in each specific application case. However, a data common to all the cases of applications is that, on the one hand, the compressibility of the material of the part 2 and, on the other hand, the level of the circular crown of the part 3 are such that, in position of use, the compression of the part 2 under the effect of a gas overpressure can release, at the edge line 5 an exhaust zone for the gases of the container responsible for this overpressure.

Pour que les gaz évacués puissent effectivement s'échapper dans . l'atmosphère, il importe qu'il y ait, dans la pièce 1 du dispositif selon l'invention ou entre la pièce 1 et le pourtour de l'orifice du récipient auquel s'adapte ce dispositif, des orifices appropriés ou des cheminements, aptes à être suivis par des gaz et débouchant dans l'atmosphère environnante. De préférence, on réalise l'évacuation des gaz dans l'atmosphère sans aucun orifice ou cheminement spécial, mais simplement en utilisant le cheminement laissé par la tolérance des cotes entre le filetage de la pièce 1 du dispositif et le filetage correspondant du goulot d'un récipient à goulot fileté.So that the exhaust gases can effectively escape into. the atmosphere, it is important that there are, in room 1 of the device according to the invention or between room 1 and the periphery of the orifice of the container to which this device adapts, suitable orifices or paths, able to be followed by gases and opening into the surrounding atmosphere. Preferably, the gas is evacuated into the atmosphere without any special opening or path, but simply by using the path left by the tolerance of the dimensions between the thread of part 1 of the device and the corresponding thread of the neck of a threaded neck container.

Bien entendu, l'invention susdite s'applique dans tous les domaines, sous réserve des nécessaires adaptations qui sont à la portée de l'homme du métier et ne font pas pour autant sortir du cadre de l'invention revendiquée.Of course, the above invention applies in all fields, subject to the necessary adaptations which are within the reach of those skilled in the art and do not, however, depart from the scope of the claimed invention.
