Description

La présente invention concerne un bouchon à visser comportant essentiellement deux éléments formés par une jupe et une bague de garantie qui est reliée par endroits à cette jupe par l'intermédiaire de petits éléments d'entretoise qui, en raison de leur faible section, peuvent être rompus lors du dévissage du bouchon.The present invention relates to a screw cap comprising essentially two elements formed by a skirt and a guarantee ring which is connected in places to this skirt by means of small spacer elements which, due to their small section, can be broken when unscrewing the cap.

Un bouchon offrant cette particularité a fait l'objet de la demande de brevet luxembourgeois n° 87469 du 8 mars 1989 au nom de la demanderesse.A stopper offering this feature was the subject of Luxembourg patent application No. 87469 of March 8, 1989 in the name of the applicant.

Le bouchon décrit par cette demande de brevet présente une structure telle que les déplacements, selon l'axe géométrique du bouchon, de la jupe par rapport à la bague de garantie ne provoquent pas une séparation prématurée, donc intempestive de ces deux éléments du bouchon. Les bouchons de ce type conçus par la demanderesse constituent donc de ce point de vue une remarquable amélioration.The stopper described by this patent application has a structure such that the displacements, along the geometrical axis of the stopper, of the skirt relative to the guarantee ring do not cause a premature, therefore untimely separation of these two elements of the stopper. The plugs of this type designed by the applicant therefore constitute a remarkable improvement from this point of view.

Il est apparu cependant que, en raison des chocs imprimés à ces bouchons au cours de leur transfert dans des machines distributrices, la bague de garantie pouvait encore se détâcher de la jupe. En effet, les chocs latéraux imprimés à ces bouchons peuvent provoquer la rupture de certains des petits éléments d'entretoise auxquels il est fait allusion dans le préambule.However, it appeared that due to the shocks to these plugs during their transfer to vending machines, the guarantee ring could still come off the skirt. Indeed, the side shocks printed on these plugs can cause the rupture of some of the small spacer elements to which reference is made in the preamble.

La présente demande de brevet a pour but de remédier à cet inconvénient très sérieux qui provoque la mise hors d'usage d'un nombre trop élevé de bouchons et exige, en tout état de cause, des vérifications qu'il y aurait lieu d'éviter.The purpose of this patent application is to remedy this very serious drawback which causes too many plugs to be put out of use and in any event requires checks which should be carried out. to avoid.

Pour réaliser cet objectif conformément à l'invention et pour permettre la production de bouchons qui ne risquent aucun dommage au cours de leurs manipulations, le bouchon à visser selon l'invention est caractérisé en ce que des deux éléments précités soit la jupe précitée (2), soit la bague de garantie précitée (3) présente, soit intérieurement, soit extérieurement, au moins localement, des prolongements (8 - 11) qui s'étendent suffisamment loin en direction de et au-delà de l'élément opposé pour empêcher toute déformation, dans le sens radial du bouchon, de la bague de garantie précitée (3), déformations qui sont à l'origine de la rupture des petits éléments d'entretoise précités (5).To achieve this objective in accordance with the invention and to allow the production of plugs which do not risk any damage during their handling, the screw plug according to the invention is characterized in that of the two aforementioned elements either the aforementioned skirt (2) or the aforementioned guarantee ring (3) has, either internally or externally, at least locally, extensions (8 - 11) which extend far enough towards and beyond the opposite element to prevent any deformation, in the radial direction of the plug, of the aforementioned guarantee ring (3), deformations which are at the origin of the rupture of the aforementioned small spacer elements (5).

D'autres détails et avantages de l'invention ressortiront de la description qui sera donnée ci-après d'un bouchon à visser équipé d'une bague de garantie, selon l'invention. Cette description n'est donnée qu'à titre d'exemple et ne limite pas l'invention. Les notations de référence se rapportent aux figures ci-jointes.Other details and advantages of the invention will emerge from the description which will be given below of a screw cap fitted with a guarantee ring, according to the invention. This description is given by way of example only and does not limit the invention. The reference notations refer to the attached figures.

La figure 1 est une vue pour moitié en coupe et pour moitié en élévation du bouchon selon l'invention dans une première forme d'exécution.Figure 1 is a view in half in section and half in elevation of the plug according to the invention in a first embodiment.

La figure 2 est une vue analogue relative à une première variante.Figure 2 is a similar view relating to a first variant.

La figure 3 est une vue analogue relative à une deuxième variante.Figure 3 is a similar view relating to a second variant.

La figure 4 et une vue analogue relative à une troisième variante.Figure 4 and a similar view relating to a third variant.

Le bouchon à visser 1 représenté par ces cinq figures comporte une jupe 2, et une bague de garantie 3.The screw cap 1 represented by these five figures comprises a skirt 2, and a guarantee ring 3.

Sur la jupe ou sur la bague de garantie peuvent être prévus des éléments d'appui protectifs 4 qui empêchent que la jupe 2 se rapprochent complètement de la bague de garantie 3 ce qui pourrait briser certains des petits éléments d'entretoise 5 qui relient la bague de garantie de la jupe.Protective support elements 4 can be provided on the skirt or on the guarantee ring which prevent the skirt 2 from coming completely close to the guarantee ring 3 which could break some of the small spacer elements 5 which connect the ring skirt warranty.

Tous ces détails, comme la présence d'une dent 6 pénétrant dans une découpe 7 de la bague de garantie 2, ont été décrits dans la demande luxembourgeoise citée plus haut.All these details, such as the presence of a tooth 6 penetrating into a cutout 7 of the guarantee ring 2, have been described in the Luxembourg application cited above.

Il est à remarquer que la présente invention vise des perfectionnements à ces bouchons mais également à d'autres types de bouchons, pourvu qu'ils comportent une jupe, une bague de garantie et de petites entretoises reliant ces éléments entre-eux.It should be noted that the present invention relates to improvements in these plugs but also in other types of plugs, provided that they include a skirt, a guarantee ring and small spacers connecting these elements between them.

Pour éviter qu'un ou plusieurs de ces petits éléments d'entretoise ne soient rompus lors des manipulations machinales, il est prévu selon la présente demande de brevet des moyens qui empêchent tout déplacement axial de la bague de garantie (3), c.à.d. tout mouvement vers l'intérieur ou l'extérieur du bouchon.To prevent one or more of these small spacer elements from being broken during mechanical manipulations, means are provided according to the present patent application which prevent any axial displacement of the guarantee ring (3), ie .d. any movement in or out of the cap.

Cet objectif peut être atteint par diverses formes d'exécution techniques possibles mais dont il est évident que certaines posent des problèmes de conception des moules d'injection.This objective can be achieved by various possible technical embodiments, but it is obvious that some of them pose problems in the design of injection molds.

En se référant à la figure 1 on remarque que la jupe 2 présente un prolongement 8 dirigé vers la bague de garantie 3. Lorsque le bouchon et la bague de garantie se trouvent dans la position représentée à la figure, c.à.d. lorsqu'il n'y a pas encore eu rupture de petits éléments d'entretoise, le prolongement 8 de la jupe 2 du bouchon s'étend suffisamment loin pour que toute déformation radiale de la bague de garantie soit empêchée. Il suffit pour cela que le prolongement 8 s'étende un dixième de millimètre ou quelques dixièmes de millimètre au-delà du bord de la bague de garantie qui est dirigée vers la jupe.Referring to Figure 1 we note that the skirt 2 has an extension 8 directed towards the guarantee ring 3. When the plug and the guarantee ring are in the position shown in the figure, i.e. when the small spacer elements have not yet broken, the extension 8 of the skirt 2 of the plug extends far enough that any radial deformation of the guarantee ring is prevented. It suffices for this that the extension 8 extends a tenth of a millimeter or a few tenths of a millimeter beyond the edge of the guarantee ring which is directed towards the skirt.

Une première variante du bouchon selon l'invention est représentée à la figure 2 où le prolongement, qui porte ici la référence 9, est prévu à l'extérieur de la bague de garantie 3. Il suffit que le prolongement 9 s'étende très légèrement au-delà du bord libre de la bague de garantie 3 pour que tout mouvement radial de cette bague de garantie soit empêché. Dans les deux cas, la bague de garantie demeure parfaitement circulaire et aucune rupture des petits éléments d'entretoise 5 n'est à craindre.A first variant of the plug according to the invention is shown in FIG. 2 where the extension, which here bears the reference 9, is provided outside the guarantee ring 3. It suffices that the extension 9 extends very slightly beyond the free edge of the guarantee ring 3 so that any radial movement of this guarantee ring is prevented. In both cases, the guarantee ring remains perfectly circular and no breakage of the small spacer elements 5 is to be feared.

La même situation est créée par la deuxième variante représentée par la figure 3 où, à l'inverse, c'est la bague de garantie 3 qui présente un prolongement, désigné par la référence 10, prévu à l'extérieur la partie de la jupe 2 du bouchon qui est dirigée vers la bague de garantie.The same situation is created by the second variant represented by FIG. 3 where, conversely, it is the guarantee ring 3 which has an extension, designated by the reference 10, provided outside the part of the skirt 2 of the plug which is directed towards the guarantee ring.

Il est clair que si les formes d'exécution les plus logiques consistent à prévoir des prolongements 8 - 10 s'étendant de manière circulaire sur tout le périmètre, soit de la jupe du bouchon, soit de la bague de garantie, ces prolongements pourraient être prévus à certains endroits seulement.It is clear that if the most logical embodiments consist in providing extensions 8 - 10 extending in a circular fashion over the entire perimeter, either of the skirt the plug or the warranty ring, these extensions could be provided in certain places only.

Dans une dernière variante il serait également possible de prolonger tous les godrons 11, ou une partie de ceux-ci. Par godron il faut entendre les saillies verticales que la jupe de certains bouchons présente à l'extérieur, généralement dans un but de faciliter le vissage et le dévissage.In a last variant it would also be possible to extend all of the gadroons 11, or a part of them. Godron means the vertical projections that the skirt of certain plugs has on the outside, generally for the purpose of facilitating screwing and unscrewing.

Quoique plusieurs modes d'exécution aient été décrits, dont certains doivent être considérés comme préférentiels du seul point de vue de la réalisation des pièces qui permettent l'injection des bouchons selon l'invention, on remarquera que toutes ces formes de réalisation réalisent le même objectif qui est d'empêcher tout mouvement radial de la bague de garantie, ces mouvements étant la cause de la rupture des petits éléments d'entretoise 5.Although several embodiments have been described, some of which must be considered preferential solely from the point of view of the production of the parts which allow the injection of the plugs according to the invention, it will be noted that all of these embodiments achieve the same objective which is to prevent any radial movement of the guarantee ring, these movements being the cause of the rupture of the small spacer elements 5.

L'invention n'est donc en principe pas limitée aux formes d'exécution décrites et bien des modifications pourraient y être apportées sans sortir du cadre de la présente demande de brevet.The invention is therefore in principle not limited to the embodiments described and many modifications could be made thereto without departing from the scope of the present patent application.
