Abstract
Description
L'invention est relative à un bouchon distribuable et vissable avec sa jupe dinviolabilité. The invention relates to a distributable and screwable cap with its tamper-evident skirt.
Il est connu de recourir à une gaine en matériau thermorétractable pour assurer, simultanément, la décora tion et l'inviolabilité d'un obturateur et,en particulier,d'un bouchon vsse sur le col a5un récipient.En général,un tronçon de gaine est déposé sur le col du récipient après obturation de celui-ci par le bouchon, puis l'ensemble -col du récipient et tronçon-est porté temporairement à une température favorisant la rétraction du tronçon sur le col et le bouchon.Outre l'amelio- ration de 11 aspect esthétique,le tronçon de gaine s'op- pose à tout dévissage du bouchon en glissant autour de ce dernier lorsqu'il est soumis à un couple de rotation. It is known practice to use a sheath made of heat-shrinkable material to ensure, simultaneously, the decoration and the inviolability of a shutter and, in particular, of a plug vsse on the neck of a container. In general, a section of sheath is placed on the neck of the container after it has been closed off by the stopper, then the entire neck of the container and the section is temporarily brought to a temperature which favors the retraction of the section on the neck and the stopper. - Ration of 11 aesthetic aspect, the sheath section opposes any unscrewing of the plug by sliding around the latter when it is subjected to a torque.
Pour dévisser le bouchon,il est donc nécessaire de déchirer le tronçon de gaine qui constitue ainsi jupe d'inviolabilité.To unscrew the cap, it is therefore necessary to tear the section of sheath which thus constitutes a tamper-evident skirt.
Ce moyen d'inviolabilité donne entière satisfaction, mais nécessite un mécanisme complexe et onéreux que ne peuvent pas se procurer les petits embouteilleurs.Pour remédier à cela,il a té envisagé de déposer et de contracter la jupe direetement sur le bouchon avant distribution et vissage e celui-ci sur le récipient.Or,cette solution n'a pas pu être retenue,car la jupe s'oppose, en raison de son faible coefficient d frottement à l'en trainement; en rotation du bouchon par les moyens habituels ménagés dans les têtes de bouchage et destines à coopérer avec les crans périphériques du bouchon. This means of inviolability is entirely satisfactory, but requires a complex and expensive mechanism that cannot be obtained by small bottlers. To remedy this, it has been envisaged to deposit and contract the skirt directly on the cap before dispensing and screwing e this one on the container. However, this solution could not be retained, because the skirt is opposed, because of its low coefficient of friction in the drive; in rotation of the plug by the usual means provided in the plugging heads and intended to cooperate with the peripheral notches of the plug.
Pour entrainer le bouchon en rotationfil serait possible de ménager,dans sa partie centrale,des bras ra du aux aptes à coopérer avec des moyens complémentaires des organes de vissage.Cependant,une telle structure ne peut pas être retenue,car ces bras,d'une part,cachent le décor apparaissant par transparence à travers le bouchon,d'autre part,constltuent des réceptacles retenant les poussières et salissures et,de plus,permettent à tout possesseur d'un organe d'entrainement denté tel qu'une fourchette,de dévisser le boucon sans détruire la jupe d'inviolabilité. In order to drive the plug in rotation, it would be possible to provide, in its central part, arms ra due to the ability to cooperate with means complementary to the screwing members. However, such a structure cannot be retained, because these arms, on the one hand, conceal the decoration appearing by transparency through the plug, on the other hand, constitute receptacles retaining dust and dirt and, moreover, allow any owner of a toothed drive member such as a fork, to unscrew the boucon without destroying the tamper-evident skirt.
La présente invention a pour but de fournir un bouchon qui,distribuable avec sa jupe dtinviolabilitépuisse être vissé sans problème sur un récipient lors du bouchage de celui-ci,mais ne puisse pas être dévissé sans destruction de sa jupe d'inviolabilité. The object of the present invention is to provide a stopper which, distributable with its tamper-proof skirt, can be screwed without problem onto a container when it is plugged, but cannot be unscrewed without destroying its tamper-evident skirt.
A cet effet,le bouchon est muni ,dans sa partie supérieure,d'une nervure périphérique comportant une denture apte à coopérer,uniquement lors du vissage,avec une denture complémentaire ménagée dans les moyens de vissage,tandis que le tronçon de gaine ceinturant ce bouchon est disposé de manière que,après rétraction,son extrémité supérieure soit en-dessous du fond de la denture du bouchon et que sa partie inférieure coiffe la face diamétrale inférieure du bouchon. To this end, the cap is provided, in its upper part, with a peripheral rib comprising a toothing capable of cooperating, only during screwing, with complementary toothing provided in the screwing means, while the sheath section encircling this stopper is arranged so that, after retraction, its upper end is below the bottom of the toothing of the stopper and its lower part covers the lower diametrical face of the stopper.
Un tel bouchon,avec la gaine thermorétractée le ceinturant,peut être aisément distribué et vissé sur un récipient par des moyens très peu différents de ceux habituels et aptes à lui communiquer un couple de vissage suffisant pour assurer l'écrasement du joint du bouchon contre la face en bout du goulot.Par contre,une fois mis en place, ce bouchon est indévissable sans déchirage de sa jupe d'in violabilité,puisque,d'une part,sa jupe d'inviolabilité s'oppose à son dévissage manuel et que,d'autre part,même en engageant dans sa denture des moyens similaires à ceux utilisés pour le visser,la forme de cette denture s'oppose à tout entrainement dans le sens du dévissage. Such a stopper, with the heat-shrunk sheath surrounding it, can be easily dispensed and screwed onto a container by means very little different from the usual ones and capable of imparting to it a sufficient screwing torque to ensure the crushing of the seal of the stopper against the face at the end of the neck. On the other hand, once put in place, this plug is inevitable without tearing its tamper-proof skirt, since, on the one hand, its tamper-evident skirt is opposed to its manual unscrewing and that , on the other hand, even by engaging in its teeth means similar to those used to screw it, the shape of this teeth opposes any training in the direction of unscrewing.
D'autres caractéristiques et avantages ressortiront de la description qui suit en référence au dessin schématique annexé représentant,à titre d'exemple non limitatif,une forme d'exécution de ce bouchon. Other characteristics and advantages will emerge from the description which follows with reference to the appended diagrammatic drawing representing, by way of nonlimiting example, an embodiment of this plug.
Figure 7 est une mae en coupe longitudinale montrant le bouchon lorsqu'il est mis en place sur le col d'un récipient,
Figure 2 est une vue de côte en élévation montrant plus particulièrement sa denture. FIG. 7 is a mae in longitudinal section showing the stopper when it is placed on the neck of a container,
Figure 2 is an elevational side view showing more particularly its teeth.
Dans ce dessin,2 désigne le col d'un récipient muni localement d'un filet extérieur hélicoïdal 3, 4 désigne un bouchon vissable en matière synthétique, 5 une coupelle métallique disposée dans le fond du bouchon et constituant réceptacle pour un joint 6. en matériau étanche et déforma ble. 2 désigne une jupe d'inviolabilité réalisée dans un matériau $d'inviolactable. In this drawing, 2 denotes the neck of a container provided locally with a helical external thread 3, 4 denotes a screwable stopper made of synthetic material, 5 a metal cup placed in the bottom of the stopper and constituting a receptacle for a seal. waterproof and deformable material. 2 denotes a tamper-evident skirt made of a tamper-evident material $.
Selon l'invention, le bouchon est muni,dans sa partie supérieure, d'une nervure périphérique 8 délimitant un puits interne 9 et; comportant ure denture 10.Comme montré plus en détail à la figure 2,cette C denture a une forme de dents de scie dont les faces droltes 11a sont dans des plans passant par l'axe longitndinal du bouchon et dont les faces inclinées 11b sont disposées de manière a ne permettre la coopération de la denture 10 ----::c une denture complémen- taire que lorsque cette denture complémentaire est entrai ne en rotation dans le sans du vissage du bouchon.Ainsi, pour un bouchon se vissant dans le sens habituel, o'est-à dire dans le même sens que celui des aiguilles d 'une montre,comme représenté par la flèche 12 à la figure 2,ses faces inclinées vont de haut en bas en pénétrant dans le bouchon lorsqu'on les regarde de droite à gauche. According to the invention, the plug is provided, in its upper part, with a peripheral rib 8 delimiting an internal well 9 and; comprising a toothing 10. As shown in more detail in FIG. 2, this C toothing has the shape of a sawtooth whose funny faces 11a are in planes passing through the longitudinal axis of the plug and whose inclined faces 11b are arranged so as to allow the cooperation of the toothing 10 ---- :: c a complementary toothing only when this complementary toothing is rotated in the without screwing the cap. Thus, for a cap screwing into the usual direction, that is to say in the same direction as that of the hands of a watch, as represented by the arrow 12 in FIG. 2, its inclined faces go from top to bottom by penetrating into the stopper when they are look from right to left.
La figure 1 montre également que na denture 10 ne dé- bouche que sur le côté extérieur de la rainure 8 et qu'elle présente un fond 13 qui est Incliné de l'intérieur vers l'extérieur en allant du sommet de la nervure 8 à la périphérie de cette même nervure0
Dans cet agencement, dès sa fabrication,le bouchon peut recevoir un tronçon de gaine 2 dont la longueur est déter- minée et qui est positionné,de manière qu'après rétraction, d'une part,l'extrémité supérieure 7a de la jupe d'inviolabilité 7 soit au-dessous du fond 13 de la denture 10 et que,d'autre part,sa partie inférieure 7b coiffe la face
diamétrale inférieure 4a du bouchon 4.FIG. 1 also shows that the toothing 10 opens only on the outside of the groove 8 and that it has a bottom 13 which is inclined from the inside towards the outside from the top of the rib 8 to the periphery of this same rib0
In this arrangement, as of its manufacture, the plug can receive a section of sheath 2 whose length is determined and which is positioned, so that after retraction, on the one hand, the upper end 7a of the skirt d inviolability 7 is below the bottom 13 of the teeth 10 and that, on the other hand, its lower part 7b covers the face
lower diameter 4a of the plug 4.
Grâce à cet agencement,la Jupe n'empeche pas l'accès à la denture 10 et,compte tenu de sa faible epaisseur,ne peut pas non plus être arrachée du bouchon pour accéder au contenu du récipient.En outre,du fait de sa rétraction sur le bouchon 4, elle forme une sorte de frette qui rigidifie ce dernier et permet,entre autres,de réduire son épaisseur,donc la quantité de matière utilisée,sans pour autant que sa résistance mécanique soit réduite. Thanks to this arrangement, the skirt does not prevent access to the toothing 10 and, given its small thickness, can not be torn off from the cap to access the contents of the container. retraction on the plug 4, it forms a sort of hoop which stiffens the latter and makes it possible, among other things, to reduce its thickness, therefore the amount of material used, without however reducing its mechanical strength.
le bouchon 4 avec sa jupe 2 rétractée sur lui peut être aisément stocké et distribué et peut donc être utilisé dans de petites installations d'embouteillage ne disposant pas de moyens pour débiter et distribuer de la gaine thermorétractable et assurer sa rétraction sur le col du récipient. the stopper 4 with its skirt 2 retracted on it can be easily stored and dispensed and can therefore be used in small bottling plants having no means for delivering and distributing heat-shrinkable tubing and ensuring its retraction on the neck of the container .
Lorsqu'un tel bouchon parvient sur le récipient,son vissage est assuré de façon connue par un outil en forme de cloche coiffant le bouchon,mais comportant dans son fond une denture complémentaire de celle 10 .Lorsque cet outil est entrainé en rotation, les faces droites de sa denture viennent buter contre celles de la denture 10 pour entrainer positivement le bouchon en rotation jusqu'à 11 obtention d'un couple de serrage suffisant pour assurer l'écrasement du joint 6 contre la face sommitale du goulot. When such a stopper reaches the container, it is screwed in known manner by a bell-shaped tool covering the stopper, but having in its bottom a toothing complementary to that 10. When this tool is rotated, the faces straight of its teeth abut against those of the teeth 10 to positively drive the rotating plug until 11 obtaining a sufficient tightening torque to ensure the crushing of the seal 6 against the top face of the neck.
Des que le bouchon est vissé,toute autre tentative de dévissage manuel est vouée à l'échec puisque le couple de rotation communiqué à la jupe d'inviolabilité 2 ne se transmet pas au bouchon-4*grâce au faible coefficient de frottement de cette jupe.De même,quand bien même l'utilisateur disposerait d'un outil comportant une denture complémentaire de celle du bouchon,il ne serait pas possible d'entrainer en rotation ce dernier,puisque, dans ce cas, les faces inclinées iib de la denture du bouchon se comporteraient comme un rochet et s'opposeraient à tout entrainement positif du bouchon.Il faut encore noter que, grâce à la réalisation de la denture sur la partie extérieure de la nervure 8,il est impossible de faire pénétrer un instrument rectiligne dans deux dents diamétralement opposées pour essayer de communiquer un couple de rotation au bouchon. As soon as the cap is screwed on, any other attempt at manual unscrewing is doomed to failure since the torque imparted to the tamper-evident skirt 2 is not transmitted to the cap-4 * thanks to the low coefficient of friction of this skirt . Similarly, even if the user would have a tool having a toothing complementary to that of the plug, it would not be possible to drive the latter in rotation, since, in this case, the inclined faces iib of the toothing of the plug would behave like a ratchet and would oppose any positive drive of the plug. It should also be noted that, thanks to the teeth on the outer part of the rib 8, it is impossible to penetrate a straight instrument into two diametrically opposed teeth to try to communicate a torque to the plug.
I1 est évident que la jupe d'inviolabilité 2 est munie de tous moyens,tel qu'une languette d'arrachage,permettant de la déchirer pour accéder au bouchon 4 lors de la première ouverture. I1 is obvious that the tamper-evident skirt 2 is provided with all means, such as a tear-off tab, making it possible to tear it in order to access the plug 4 during the first opening.
