Description
La présente invention est relative à des perfectionnements apportés auxThe present invention relates to improvements made to the
obturateurs inviolables réalisés en matière thermo-plastique et tamperproof shutters made of thermoplastic material and
comprenant une capsule filetée et une bague de garantie propre à s'enclen- comprising a threaded cap and a ring of guarantee
cher élastiquement dans une gorge du goulot d'un récipient. elastically in a neck groove of a container.
Les obturateurs du genre en question comportent une série de ponts de liaison de la capsule et de la bague qui se rompent lors du dévissage de la capsule. La section des ponts considérés doit donc être faible pour que leur rupture soit effective dès qu'on commence le dévissage de la capsule. Lors du démoulage de tels obturateurs la capsule est mise en rotation par un dispositif de dévissage qui extrait par élasticité le cordon intérieur de la bague de garantie hors de la gorge ayant permis de la mouler. Il s'ensuit une traction importante qui est encaissée par les ponts de liaison. Comme ils présentent une section réduite, il se produit The shutters of the kind in question comprise a series of connecting bridges of the capsule and the ring which break during the unscrewing of the capsule. The section of the bridges considered must be low so that their rupture is effective as soon as the unscrewing of the capsule is begun. When demolding such shutters the capsule is rotated by an unscrewing device which elastically pulls the inner cord of the guarantee ring out of the groove that has made it possible to mold it. It follows a significant traction that is cashed by the connecting bridges. As they have a reduced section, it occurs

teur doit être rebuté. Il est donc nécessaire que la température de démoulage des pièces soit très attentivement surveillée car le démoulage doit s'effectuer lorsque la matière est encore suffisamment chaude pour que l'extraction du cordon d'encliquetage de la bague de garantie ne must be put off. It is therefore necessary that the demolding temperature of the parts be very carefully monitored because the demoulding must take place when the material is still hot enough so that the extraction of the ratchet of the ring of guarantee does not
nécessite pas une force de traction trop importante. does not require too much traction force.
On est donc conduit à dimensionner les ponts de liaison de manière qu'ils résistent aux efforts d'éjection sans toutefois que leur section It is therefore necessary to size the connecting bridges so that they resist the ejection forces without their section
entraîne des difficultés de rupture lors du dévissage de l'obturateur. causes breakage difficulties when unscrewing the shutter.
Lorsque l'on met en place sur le goulot fileté d'une bouteille un obturateur tel que celui décrit plus haut, il est contenu dans une matrice qui entoure toute sa périphérie y compris celle de sa bague de garantie et qui est destinée à visser la capsule sur le filetage du goulot. Etant donné les cadences élevées de mise en place, l'effort axial subi par la bague de garantie est important dès que son cordon intérieur vient en contact avec la bague du goulot du récipient. On assiste donc When a shutter such as the one described above is placed on the threaded neck of a bottle, it is contained in a matrix which surrounds its entire periphery including that of its guarantee ring and which is intended to screw the capsule on the thread of the neck. Given the high rates of implementation, the axial force experienced by the ring guarantee is important as soon as its inner bead comes into contact with the collar of the neck of the container. We are therefore witnessing
très souvent à des ruptures par flambage des ponts de liaison. very often to buckling breaks connecting bridges.
Les perfectionnements qui font l'objet de la présente invention visent à remédier à cet inconvénient et à permettre la réalisation d'un obturateur comportant une capsule filetée et une bague inférieure de garantie dont les ponts de liaison ne puissent par flamber, et par conséquent ne se rompent pas sous l'effet de l'effort axial appliqué à la The improvements which are the object of the present invention are intended to remedy this drawback and to allow the realization of a shutter comprising a threaded cap and a lower guarantee ring whose connecting bridges can not flare up, and therefore do not do not rupture under the effect of the axial force applied to the
bague en direction de la capsule.ring towards the capsule.
A cet effet, le bord inférieur libre de la jupe de la capsule comporte des butées d'appui situées au voisinage immédiat des ponts de liaison de telle sorte que lors de la mise en place d'un obturateur ainsi agencé sur le goulot d'une bouteille, ce soient lesdites butées qui travaillent en compression à la place des ponts de liaison. Bien entendu la forme des butées est telle qu'elles permettent le démoulage des obturateurs, c'està-dire qu'elle présente des faces dépouillées en For this purpose, the free bottom edge of the skirt of the capsule comprises abutments located in the immediate vicinity of the connecting bridges so that when placing a shutter and arranged on the neck of a bottle, it is said stops which work in compression instead of connecting bridges. Of course the shape of the abutments is such that they allow the release of the shutters, that is to say it has stripped faces in
direction de l'extérieur.direction from the outside.
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 partielle d'un obturateur usuel comportant une capsule filetée et une bague de garantie située dans le prolongement de The accompanying drawing, given by way of example, will provide a better understanding of the invention, the characteristics it has and the advantages it is likely to provide: FIG. 1 is a partial section of a conventional shutter having a threaded cap and a guarantee ring located in the extension of
la jupe de ladite capsule.the skirt of said capsule.
Fig. 2 illustre en coupe la manière dont un obturateur tel Fig. 2 illustrates in section how a shutter such
que celui de fig. 1 est mis en place sur le goulot d'une bouteille. that of fig. 1 is put in place on the neck of a bottle.
Fig. 3 est une vue extérieure avec arrachement de l'obturateur Fig. 3 is an external view with tearing of the shutter
établi conformément à l'invention. established according to the invention.
Fig. 4 en est une coupe suivant IV-IV (fig. 3). Fig. 4 is a section along IV-IV (Fig. 3).
On a représenté en fig. 1 un obturateur affecté de la référence générale 1 et qui comporte une capsule filetée 2 et une bague de garantie 3 reliées par des ponts de liaison 4 assurant l'inviolabilité. Un tel obturateur bien connu dans la pratique est en particulier révélé dans le brevet antérieur N0 70 00832. Sa capsule est destinée à être vissée sur It is shown in fig. 1 a shutter affected by the general reference 1 and which comprises a threaded cap 2 and a guarantee ring 3 connected by connecting bridges 4 ensuring the inviolability. Such a shutter well known in the art is in particular disclosed in the prior patent No. 70 00832. Its capsule is intended to be screwed onto
le filetage 5a du goulot d'un récipient tel qu'une bouteille 5 (fig. 2). the thread 5a of the neck of a container such as a bottle 5 (FIG 2).
La face intérieure de la bague 3 comporte un cordon 3a qui fait saillie en vue de s'encliqueter élastiquement sous un épaulement 5b déterminé par un renflement 5c ménagé à la périphérie du goulot en dessous de son The inner face of the ring 3 comprises a cord 3a which protrudes in order to snap elastically under a shoulder 5b determined by a bulge 5c formed at the periphery of the neck below its
filetage 5a.thread 5a.
Pour effectuer la mise en place de l'obturateur 1 sur le goulot du récipient 5, on utilise une matrice 6 dans laquelle l'obturateur 1 est engagé, et qui est solidaire de la tête de la machine de bouchage. Cette tête est tout d'abord déplacée axialement en direction de la bouteille 5, puis elle est soumise à un mouvement de rotation qui provoque le vissage de la capsule 2 sur le filetage 5a de la bouteille 5. Le cordon 3a de la bague 3 vient coopérer avec le dessus du renflement 5c ce qui provoque un effort axial important entre cette bague et la capsule 2 de telle manière que les ponts de liaison 4 qui réunissent les deux éléments considérés de l'obturateur subissent un flambage important conduisant souvent à leur rupture. Conformément à l'invention, on prévoit de ménager sur le bord To carry out the introduction of the shutter 1 on the neck of the container 5, a die 6 is used in which the shutter 1 is engaged, and which is integral with the head of the capping machine. This head is first moved axially towards the bottle 5, then it is subjected to a rotational movement which causes the screwing of the cap 2 on the thread 5a of the bottle 5. The cord 3a of the ring 3 comes cooperate with the top of the bulge 5c which causes a significant axial force between the ring and the capsule 2 in such a way that the connecting bridges 4 which join the two considered elements of the shutter undergo significant buckling often leading to their rupture. According to the invention, provision is made to spare on the edge

butées d'appui 7 situées au voisinage immédiat des ponts de liaison 4. bearing abutments 7 located in the immediate vicinity of the connecting bridges 4.
On a illustré fig. 4 les butées 7 qui se présentent sous la forme de picots à section transversale triangulaire et qui occupent l'épaisseur du bord libre inférieur 2a de la capsule 2. Le sommet de la section transversale triangulaire de chaque butée 7 se trouve à l'extérieur de manière à faciliter le démoulage, si bien qu'elle se présente sous la forme d'un prisme à paroi latérale en dépouille. En réalité, l'arête We have illustrated fig. 4 abutments 7 which are in the form of triangular cross section pins and which occupy the thickness of the lower free edge 2a of the capsule 2. The vertex of the triangular cross section of each abutment 7 is outside of to facilitate demolding, so that it is in the form of a sidewall prism stripped. In reality, the ridge
verticale de chaque butée est arrondie afin d'être moins visible. vertical of each stop is rounded to be less visible.
On observe qu'en pratique la hauteur des butées 7 est légèrement inférieure à celle des ponts 4, un jeu de 0,4 mm étant par exemple prévu par une hauteur desdits ponts de 1 mm. Mais bien entendu ce jeu n'est pas nécessairement de cette importance; il suffit qu'il permette le moulage des butées 7 de manière que leurs extrémités libres soient séparées de la It is observed that in practice the height of the abutments 7 is slightly less than that of the bridges 4, a set of 0.4 mm being for example provided by a height of said bridges of 1 mm. But of course this game is not necessarily of this importance; it suffices that it allows the molding of the abutments 7 so that their free ends are separated from the
bague 3.ring 3.
Lors de la mise en place de l'obturateur il se produit une faible compression des ponts de liaison 4 dont la déformation est limitée à la valeur du jeu entre les extrémités libres des butées 7 et le dessus de la bague 3, puisqu'au-delà de cette valeur ce sont les butées qui encaissent During the introduction of the shutter there is a low compression of the connecting bridges 4 whose deformation is limited to the value of the clearance between the free ends of the stops 7 and the top of the ring 3, since Beyond this value are the stops that cash

Etant donné la section de chaque butée 7, on peut diminuer au maximum celle des ponts de liaison 4 puisqu'ils n'encaissent pratiquement aucun effort lors de la mise en place. La section considérée des ponts de liaison n'est donc déterminée que par leur résistance à la traction Given the section of each abutment 7, one can reduce as much as the connecting bridges 4 since they hardly incur any effort during installation. The considered section of the connecting bridges is therefore determined only by their tensile strength

On a ainsi réalisé un obturateur inviolable dont les ponts de liaison 4 ne subissent aucun effort lors de sa mise en place sur le goulot fileté d'un récipient, leur section étant alors suffisamment faible pour assurer leur rupture immédiate dès le début du dévissage de It has thus been realized a tamper-proof shutter whose connection bridges 4 do not undergo any effort when it is placed on the threaded neck of a container, their section then being small enough to ensure their immediate rupture from the beginning of the unscrewing of
