Description

Dispositif de scellé à support d'identification et moule d'injection pour sa fabrication. Sealing device with identification support and injection mold for its manufacture.
La présente invention concerne le domaine des dispositifs de scellés, en particulier pour la protection d' appareillages contre le vandalisme ou pour la protection ou la fermeture ou l'identification d'appareillages, de contenants ou d'obj ets. Des dispositifs de scellés couramment utilisés comprennent une pastille munie d'un fil flexible susceptible d' être engagé au travers d'un trou traversant de la pastille, des moyens permettant de maintenir le fil dans le trou afin de constituer une boucle inviolable. Le brevet FR-A-2 725 542 décrit un dispositif de scellé monobloc en matière plastique qui comprend une pastille qui présente un trou traversant réalisé parallèlement à ses grandes faces et un fil perlé s' engageant dans le trou de la pastille de façon à constituer une boucle, la pastille pouvant être écrasée par sertissage dans le sens de son épaisseur de telle sorte que le fil est fermement maintenu dans la pastille. Le brevet CH-A-684 137 décrit un dispositif d' étiquetage monobloc en matière plastique qui comprend une plaque qui présente un trou réalisé dans le sens de son épaisseur, dont le bord est d' épaisseur réduite, et un fil s' engageant dans le trou de la plaque et présentant des parties en saillie d' accrochage dans ce trou. Un tel dispositif est démontable sans dommage. Le brevet GB-A-2 164 003 décrit un dispositif de scellé en matière plastique qui comprend une boîte munie d'un fil présentant à son extrémité libre des dents d' accrochage et, dans cette boîte, des parties d'accrochage pour retenir en prise ces dents lorsque cette extrémité libre est engagée dans la boîte. Un tel dispositif présente l' inconvénient de devoir être fabriqué en plusieurs parties qui doivent ensuite être assemblées. Les brevets EP-A- 0 924 677 et US-A- 4 001 919 décrivent des dispositifs de scellés qui comprennent un fil cylindrique présentant des parties annulaires en saillie et une pastille présentant un passage traversant au travers duquel peut être engagé le fil, la pastille présentant, dans ce passage, des lèvres en saillie susceptibles de s' accrocher sur les parties en saillie du fil. De tels dispositifs ne sont cependant pas très résistants et présentent des applications très limitées. Par ailleurs, de façon courante, la pastille peut porter des informations d' identification qui sont soit préalablement réalisées lors du moulage soit réalisées lors de l' écrasement de la pastille autour du fil inséré dans le trou de cette dernière par un outil présentant une empreinte. La présente invention a pour but de proposer un perfectionnement aux dispositifs de scellés. La présente invention concerne un dispositif de scellé qui comprend une pastille, un fil flexible et des moyens d' accrochage pour relier le fil à la pastille de façon à constituer une boucle. Selon un objet de l' invention, ce dispositif de scellé comprend en outre un support, des moyens d'emboîtement pour accoupler ce support à ladite pastille et des moyens de verrouillage pour verrouiller de façon irréversible ledit support et ladite pastille, ces moyens de verrouillage comprenant une partie destructible solidaire de ladite pastille. Selon l'invention, pour constituer lesdits moyens de verrouillage, ledit support et ladite pastille comprennent de préférence des trous traversants au travers desquels ledit fil flexible est susceptible d' être engagé lorsqu' ils sont accouplés. Selon l'invention, ledit support et/ou ladite pastille comprennent de préférence des moyens coupants pour couper ledit fil flexible lors de la séparation du support et de la pastille préalablement accouplés. Selon l'invention, pour constituer lesdits moyens d'emboîtement, ledit support et ladite pastille comprennent de préférence des parties complémentaires s' engageant l'une dans l' autre. Selon l'invention, pour constituer lesdits moyens de verrouillage, lesdites parties complémentaires dudit support et de ladite pastille comprennent de préférence des trous traversants situés en face les uns des autres lorsqu' ils sont accouplés et au travers desquels ledit fil flexible est susceptible d' être engagé. Selon l'invention, lesdites parties complémentaires comprennent de préférence des parties adjacentes situées dans la zone desdits trous traversants, dont au moins l'une présente un bord coupant pour couper ledit fil flexible lors de la séparation du support et de la pastille préalablement accouplés. Selon l'invention, ledit support comprend de préférence une chambre pour la réception d'un organe d'identification. Selon l'invention, l' ouverture d' accès pour l' insertion dudit organe d' identification dans ladite chambre du support peut avantageusement être fermée par mise en contact et thermosoudage des parties de ce support délimitant cette ouverture. Selon l'invention, ledit organe d' identification est de préférence constitué par un circuit électronique comprenant une puce de circuits intégrés, éventuellement reprogrammable.

La présente invention sera mieux comprise à l' étude de dispositifs de scellés décrits à titre d'exemples non limitatifs et illustrés par le dessin sur lequel : la figure 1 représente une vue en perspective d' un dispositif de scellé selon l'invention en position désaccouplée ; la figure 2 représente une vue en perspective du dispositif de scellé de la figure 1 en position emboîtée et verrouillée ; - la figure 3 représente une coupe longitudinale horizontale ou à plat du dispositif de scellé selon l' invention en position emboîtée ; la figure 4 représente une coupe longitudinale verticale du di spositif de scellé selon l'invention en position emboîtée ; - la figure 5 représente une coupe longitudinale à plat du di spositif de scellé selon l' invention en position emboîtée et verrouillée. la figure 6 représente une vue de dessus d'un dispositif de scellé selon la présente invention, apte à constituer une partie du di spositif de scellé précité, dans laquelle la pastille est en coupe ; la figure 7 représente une vue agrandie en coupe de la pastille accouplée au fil, du dispositif de scellé de la figure 6 ; la figure 8 représente une coupe transversale de la pastille du dispositif de scellé de la figure 6 ; - la figure 9 représente une vue en perspective et en coupe transversale de la pastille du dispositif de scellé de la figure 6 ; la figure 10 représente un moule pour la fabrication du dispositif de scellés du dispositif de scellé de la figure 6 , en coupe perpendiculairement à son plan de joint et parallèlement aux faces de la pastille ; la figure 1 1 représente une coupe du moule de la figure 10, perpendiculairement à son plan de joint et perpendi-culairement aux faces de la pastille ; et la figure 12 représente une coupe du moule de la figure 10 en un endroit du fil flexible à réaliser. Le dispositif de scellé 1 représenté sur les figures 1 à 5 comprend une première partie 2, par exemple en une matière plastique et réalisée en une seule pièce, qui comprend une pastille plate 3 de forme parallélépipédique et un fil flexible 4 qui s' étend par exemple à partir du milieu d' un petit côté 5 de la pastille 3. Parallèlement à sa petite face 5 et à ses grandes faces, la pastille 3 présente un trou traversant 6 au travers duquel peut être engagé le fil flexible 4. Sensiblement au milieu de sa longueur, le trou traversant 6 présente des dents d' accrochage 7 intérieurement en saillie. En différents endroits de sa longueur, le fil flexible 4 présente des dents annulaires d' accrochage 8 extérieurement en saillie. Les dents intérieures d' accrochage 7 de la pastille 3 et les dents extérieures d' accrochage 8 du fil flexible 4 sont telles qu' elles autorisent l'engagement du fil flexible 4 dans le trou 6 de la pastille 3 mais qu' elles interdisent son extraction, sauf à les rompre ou à rompre le fil flexible 4. Le dispositif de scellé 1 comprend en outre une seconde partie 9, par exemple en une matière plastique et réalisée en une seule pièce, constituant un support. Ce support 9 est plat et de forme générale parallélépipédique. Parallèlement à ses grandes faces, le support 9 présente une chambre longitudinale principale 10, parallélépipédique, ouverte sur un petit côté 1 1 de ce support. Cette chambre 10 est de forme complémentaire à celle de la pastille 3 , de telle sorte que la pastille 3 peut être engagée par emboîtement dans la chambre 10, jusqu' à ce que le côté 5 de la pastille 3 vienne sensiblement affleurer le côté 1 1 du support 9, le fil flexible 4 restant à l' extérieur. De part et d' autre de la chambre 10 et parallèlement à ses grandes faces, le support 9 présente des trous traversants 12 qui, lorsque la pastille 3 est emboîtée dans la chambre 10, sont situés en face des extrémités du trou traversant 6 de cette pastille. Ainsi, lorsque la pastille 3 est emboîtée dans la chambre 10 du support 9, le fil flexib le 4 peut être engagé, non seulement au travers du trou traversant 6 de la pastille 3 mais également et en même temps au travers des trous traversants 12 du support 9 situés de part et d' autre, de telle sorte que la pastille 3 et le support 9 soient alors verrouillés l'un avec l' autre. Les trous traversants 12 du support 9 sont de forme sensiblement tronconique ouverte vers l' extérieur, de telle sorte que leurs bords intérieurs adjacents à la chambre 10 sont d' épaisseurs réduites et constituent des couteaux coupants 13 de destruction du fil flexible 4. Ainsi, lorsque la pastille 3 est emboîtée dans la chambre 10 du support 9 et que le fil flexible 4 être engagé au travers du trou traversant 6 de la pastille 3 et des trous traversants 12 du support 9, il est possible de couper ou rompre par cisaillement le fil flexible 4 sous l'effet des couteaux 13 lorsque l' on extrait la pastille 3 de la chambre 10 du support 9, par exemple en tirant sur la partie du fil 4 adj acente à la pastille 3. A l'opposé de sa chambre 10 et parallèlement à ses grandes faces, le support 9 présente en outre une chambre longitudinale secondaire 14 dans laquelle est enfermé longitudinalement un circuit électronique 15 de petites dimensions. Pour installer ce circuit électronique, on peut tout d' abord fabriquer un support 9 présentant une chambre 14 présentant une ouverture par exemple sur le côté 16 du support opposé à son côté 1 1 , mettre en place le circuit électronique 15 dans la chambre 14, mettre en contact les bords 17 de cette ouverture et les thermo-souder dans le but de fermer la chambre 14 et d' emprisonner le circuit électronique 15 de façon étanche. Le circuit électronique 15 comprend une puce de circuits intégrés présentant des mémoir es d' informations et des moyens pour les lire, par exemple à distance, des moyens pouvant être prévus pour reprogrammer ces mémoires, par exemple à distance, afin de modifier les informations qu' elles contiennent. Un tel circuit électronique est connu en soi. Avantageusement, lesdites informations peuvent être des données d'identification associ ées ou associables au dispositif de scellé 1, telles que, d'une manière générale, des données d'identification de personnes, d'identification d' obj ets, d' identification liées au temps, d'identification de lieux, d'identification de valeur ou de toutes autres données utiles. Le dispositif de scellé 1 qui vient d'être décrit peut être utilisé de la manière suivante. Disposant d'une part d'une première partie 2 constituée de la pastille 3 et du fil flexible 4 et d'autre part d'un support 9 renfermant un circuit électronique 15 à mémoires d'informations d'identification programmées, on emboîte la pastille 3 dans la chambre 10 du support 9 ; on passe le fil flexible 4 au travers ou autour d'une partie d'un objet à protéger ou à identifier ; et on engage, par son extrémité libre, le fil flexible 4 au travers des trous traversants correspondants 6 et 12 de la pastille 3 et du support 9, en mettant en prise les dents d' accrochage 7 et 8 ; ce pour former un boucle de la dimension souhaitée. Devant ôter le dispositif de scellé 1 de l' obj et sur lequel il a été précédemment installé, on procède, grâce aux couteaux 13 , à la rupture du fil flexible 4 en extrayant la pastille 3 de la chambre 10 du support 9. La première partie 2 constituée de la pastille 3 et du fil flexible 4 n'est alors plus utilisable mais le support 9 renfermant le circuit électronique 15, resté intact, est à nouveau utilisable et pourra être réutilisé, éventuellement en ayant reprogrammé sa puce 18, avec une première partie 2 neuve pour être installé sur le même obj et ou sur un autre obj et. Le dispositif de scellé 1 peut avantageusement être appliqué dans le domaine de la surveillance de l'usage ou de la protection d' objets, de machines ou d'appareillages tels que les compteurs d' électricité, de gaz ou d' eau, dans le domaine de la protection et du contrôle d' obj ets à transporter tels que des valises, des sacs postaux, de pièces de monnaie ou de billets de banque ou encore dans les domaines nécessitant une surveillance des parcours d' objets ou de produits, généralement appelés la traçabilité. En se reportant maintenant aux figures 6 à 9, on peut voir qu'on a représenté un dispositif de scellé 101 apte à constituer la partie 2 du dispositif de scellé 1 décrit en référence aux figures 1 à 5. Le dispositif de scellé 101 est monobloc et en matière plastique, par exemple en polyamide résistant. Il comprend une pastille rectangulaire 102 qui présente des grandes faces opposées 103 et 104 ainsi que des côtés opposés 105 et 106 et des côtés opposés 107 et 108. La pastille 102 présente un trou traversant médian 109, généralement cylindrique, qui s' étend parallèlement à ses grandes faces 103 et 104 et à ses côtés 105 et 106 et qui débouche sur ses côtés 107 et 108. Dans le trou traversant 109, sensiblement à mi-longueur, sont prévues deux lèvres opposées d' accrochage 1 10 et 1 1 1 en saillie, espacées circonférentiellement. Le dispositif de scellés 101 comprend également un fil flexibleThe present invention relates to the field of seal devices, in particular for the protection of devices against vandalism or for the protection or closure or identification of devices, containers or objects. Commonly used seal devices include a patch with a flexible wire capable of being engaged through a through hole in the patch, means for holding the wire in the hole to form a tamper-evident loop.

Such a device is removable without damage. GB-A-2 164 003 describes a plastic sealing device which comprises a box provided with a wire having at its free end hooking teeth and, in this box, hooking parts for retaining in taken these teeth when this free end is engaged in the box. Such a device has the disadvantage of having to be manufactured in several parts which must then be assembled. The patents EP-A-0 924 677 and US-A-4 001 919 describe seal devices which include a cylindrical wire having annular projecting parts and a pellet having a through passage through which the wire can be engaged, the pellet having, in this passage, projecting lips capable of catching on the projecting parts of the wire. However, such devices are not very resistant and have very limited applications. Furthermore, commonly, the patch may carry identification information which is either previously produced during molding or carried out when the tablet is crushed around the wire inserted into the hole of the latter by a tool having an imprint. . The object of the present invention is to propose an improvement to seal devices. The present invention relates to a sealing device comprising a patch, a flexible wire and hooking means for connecting the wire to the patch so as to form a loop.

According to the invention, the inner cylindrical faces of said lips are preferably adapted to wrap the cylindrical parts of the wire at a short distance. The present invention also relates to an injection mold for the production of a pellet provided with a flexible wire, the pellet having a through hole for receiving the wire and thus constituting a loop and the pellet and the wire having means of hanging. According to the invention, said mold preferably comprises at least two parts delimiting between them at least one main cavity for the production of at least one pellet and at least one complementary cavity communicating with the main cavity for the manufacture of 'an elongated wire connected to the patch and preferably comprises at least one elongated insert passing through said cavity for the production of at least one hole passing through said patch parallel to its large faces.

The sealing device 1 shown in FIGS. 1 to 5 comprises a first part 2, for example made of a plastic material and produced in one piece, which comprises a flat patch 3 of parallelepiped shape and a flexible wire 4 which extends through example from the middle of a small side 5 of the patch 3. Parallel to its small face 5 and to its large faces, the patch 3 has a through hole 6 through which the flexible wire can be engaged 4. Significantly in the middle of its length, the through hole 6 has internally projecting hooking teeth 7. At different places along its length, the flexible wire 4 has annular hooking teeth 8 projecting from the outside. The inner hooking teeth 7 of the pad 3 and the outer hooking teeth 8 of the flexible wire 4 are such that they allow the flexible wire 4 to be engaged in the hole 6 of the pad 3 but that they prohibit its extraction, except to break them or to break the flexible wire 4. The sealing device 1 further comprises a second part 9, for example made of a plastic material and produced in one piece, constituting a support. This support 9 is flat and of generally parallelepiped shape. Parallel to its large faces, the support 9 has a main longitudinal chamber 10, parallelepiped, open on a small side 1 1 of this support. This chamber 10 is of complementary shape to that of the patch 3, so that the patch 3 can be engaged by interlocking in the chamber 10, until the side 5 of the patch 3 comes substantially flush with the side 1 1 of the support 9, the flexible wire 4 remaining outside. On either side of the chamber 10 and parallel to its large faces, the support 9 has through holes 12 which, when the wafer 3 is fitted into the chamber 10, are located opposite the ends of the through hole 6 of this pellet. Thus, when the patch 3 is fitted into the chamber 10 of the support 9, the flexib wire 4 can be engaged, not only through the through hole 6 of the patch 3 but also and at the same time through the through holes 12 of the support 9 located on either side, so that the pad 3 and the support 9 are then locked with each other. The through holes 12 of the support 9 are of substantially frustoconical shape open towards the outside, so that their internal edges adjacent to the chamber 10 are of reduced thickness and constitute cutting knives 13 for destroying the flexible wire 4. Thus, when the pad 3 is fitted into the chamber 10 of the support 9 and the flexible wire 4 is engaged through the through hole 6 of the pad 3 and through holes 12 of the support 9, it is possible to cut or break by shearing flexible wire 4 under the effect of the knives 13 when the pellet 3 is extracted from the chamber 10 from the support 9, for example by pulling on the part of the wire 4 adjacent to the pellet 3. Opposite its chamber 10 and parallel to its large faces, the support 9 also has a secondary longitudinal chamber 14 in which is longitudinally enclosed an electronic circuit 15 of small dimensions. To install this electronic circuit, it is first of all possible to manufacture a support 9 having a chamber 14 having an opening for example on the side 16 of the support opposite its side 11, put the electronic circuit 15 in the chamber 14, bring the edges 17 of this opening into contact and heat seal them in order to close the chamber 14 and trap the electronic circuit 15 tightly. The electronic circuit 15 comprises an integrated circuit chip presenting information memories and means for reading them, for example remotely, means which can be provided for reprogramming these memories, for example remotely, in order to modify the information that ' they contain. Such an electronic circuit is known per se. Advantageously, said information can be identification data associated with or associated with the seal device 1, such as that, in general, personal identification data, object identification, time-related identification, location identification, value identification or any other useful data. The seal device 1 which has just been described can be used in the following manner. Having on the one hand a first part 2 consisting of the pad 3 and the flexible wire 4 and on the other hand of a support 9 containing an electronic circuit 15 with programmed identification information memories, the pad is fitted 3 in the chamber 10 of the support 9; the flexible wire 4 is passed through or around a part of an object to be protected or identified; and engaging, by its free end, the flexible wire 4 through the corresponding through holes 6 and 12 of the pad 3 and of the support 9, by engaging the hooking teeth 7 and 8; this to form a loop of the desired dimension. Before removing the sealing device 1 from the object and on which it was previously installed, we proceed, using knives 13, to break the flexible wire 4 by extracting the disc 3 from the chamber 10 of the support 9. The first part 2 consisting of the patch 3 and the flexible wire 4 is then no longer usable but the support 9 containing the electronic circuit 15, remaining intact, is again usable and can be reused, possibly having reprogrammed its chip 18, with a first part 2 new to be installed on the same object and or on another object and. The seal device 1 can advantageously be applied in the field of monitoring the use or protection of objects, machines or equipment such as electricity, gas or water meters, in the field of protection and control of objects to be transported such as suitcases, postal bags, coins or banknotes or in fields requiring surveillance of the course of objects or products, generally called traceability. Referring now to FIGS. 6 to 9, it can be seen that a seal device 101 has been shown capable of constituting part 2 of the seal device 1 described with reference to FIGS. 1 to 5. The sealing device 101 is in one piece and made of plastic, for example of resistant polyamide. It includes a rectangular patch 102 which has large opposite faces 103 and 104 as well as opposite sides 105 and 106 and opposite sides 107 and 108. The patch 102 has a median through hole 109, generally cylindrical, which extends parallel to its large faces 103 and 104 and at its sides 105 and 106 and which opens on its sides 107 and 108. In the through hole 109, substantially at mid-length, there are provided two opposite hooking lips 1 10 and 1 1 1 in protruding, circumferentially spaced. The seal device 101 also includes a flexible wire
1 12 qui s' étend par exemple à partir du côté 106 de la pastille 102, perpendiculairement. Ce fil 1 12 est généralement cylindrique et est susceptible d' être introduit au travers du trou traversant 109 de la pastille 102 de façon à former une boucle. Le fil 1 12 présente des parties annulaires d' accrochage 1 13 en saillie, espacées et réparties sur une partie médiane de sa longueur. Le trou traversant 109 de la pastille 102 et le fil 1 12 sont adaptés de façon que le fil 1 12 soit guidé longitudinalement dans le trou traversant 109 de la pastille 102 et les parties annulaires d' accrochage1 12 which extends for example from the side 106 of the patch 102, perpendicularly. This wire 1 12 is generally cylindrical and is capable of being introduced through the through hole 109 of the patch 102 so as to form a loop. The wire 1 12 has annular hooking parts 1 13 projecting, spaced apart and distributed over a median part of its length. The through hole 109 of the patch 102 and the wire 1 12 are adapted so that the wire 1 12 is guided longitudinally in the through hole 109 of the patch 102 and the annular hooking parts.
1 13 du fil 1 12 sont susceptibles de passer au-dessus des lèvres d'accrochage 1 10 et 1 1 1 et de coopérer avec ces dernières de façon à empêcher le retrait du fil 1 12 après qu'il ait été introduit dans le trou1 13 of the wire 1 12 are capable of passing over the hooking lips 1 10 and 1 1 1 and of cooperating with the latter so as to prevent the withdrawal of the wire 1 12 after it has been introduced into the hole
109 de la pastille 102. En se reportant aux figures 10 à 12, on va maintenant décrire un moule d' injection 1 14 conçu spécialement pour la réalisation du dispositif de scellé 101. Ce moule d'injection 1 14 comprend deux parties 1 15 et 1 16 accolées par un plan de joint 1 17. Dans les parties 115 et 1 16 est formée une cavité principale 1 1 8 pour la réalisation de la pastille 102, cette cavité 1 1 8 étant symétrique par rapport au plan de joint 1 17 et formée de telle sorte que les grandes faces 103 et 104 de la pastille à réaliser s' étendent perpendiculairement à ce plan de joint 1 17. En vue de la réalisation du trou traversant 109 de la pastille et des lèvres 1 10 et 1 1 1 en saillie dans ce trou traversant 109, le moule 1 14 est équipé d'un insert allongé 120 qui traverse la cavité 1 18 perpendiculairement à son plan de joint 1 17 et qui comprend deux parties 120 et 121 qui présentent des parties d' extrémité 122 et 123 adjacentes et accouplées. Dans la cavité 118, la partie d' insert 120 comprend un cylindre 124 qui présente un trou axial 125. L ' épaulement frontal annulaire 126 du cylindre 124 ainsi réalisé présente deux portions de faces frontales tronconiques 127a et 127b, opposés et symétriques, dont le sommet est situé vers l' avant, ainsi que deux méplats opposés et symétriques 128a et 128b plus inclinés que ces faces tronconique 127a et 1 27b et réalisés dans ces dernières. Ainsi, l' épaulement frontal annulaire 125 est convexe. Dans le trou axial 125 du cylindre 124 est monté un ergot cylindrique 129 dépassant vers l' avant. Dans la cavité 1 18, la partie d'insert 121 comprend un cylindre 130 dont le diamètre est légèrement supérieur au diamètre du cylindre 124 de la partie d'insert 120 et qui présente dans sa partie d' extrémité •123 un évidement axial 13 1. L' épaulement frontal ainsi réalisé présente une face frontale tronconique 132 dont la pointe est dirigée vers l' arrière et de même conicité que les faces tronconiques 127a et 127b de la partie d'insert 120. Ainsi, la face frontale tronconique 132 est concave. Lorsque les parties d'insert 120 et 121 sont accouplées et en position de moulage, l' ergot 129 de la partie d'insert 120 est engagé juste dans l'évidement 131 de la partie d'insert 130 et les faces frontales tronconiques opposées 127a et 127b de la partie d' insert 120 sont en contact ou en appui sur deux parties opposées de la face frontale tronconique 132 de la partie d'insert 121 , tandis qu' entre les méplats opposés et inclinés 128a et 129a de la partie d' insert 120 et les autres parties opposées de la partie d'insert 121 , situées en vis-à-vis de la face frontale tronconique 132, déterminent des espaces opposés et symétriques 133 et 134, ouverts latéralement et inclinés, dont les volumes et les formes correspondent aux lèvres 110 et 111 à réaliser. Ainsi, l'épaisseur des espaces 133 et 134 augmente de leur partie d'extrémité circonférentielle à leur partie médiane et leur épaisseur augmente depuis l'ergot 129 jusqu'à leur périphérie, les espaces 133 et109 of the patch 102. Referring to Figures 10 to 12, we will now describe an injection mold 1 14 specially designed for the production of the seal device 101. This injection mold 1 14 comprises two parts 1 15 and 1 16 joined by a joint plane 1 17. In parts 115 and 1 16 is formed a main cavity 1 1 8 for the production of the patch 102, this cavity 1 1 8 being symmetrical with respect to the joint plane 1 17 and formed so that large faces 103 and 104 of the patch to be produced extend perpendicular to this joint plane 1 17. With a view to making the through hole 109 of the patch and the lips 1 10 and 1 1 1 projecting into this through hole 109, the mold 1 14 is equipped with an elongated insert 120 which passes through the cavity 1 18 perpendicular to its joint plane 1 17 and which comprises two parts 120 and 121 which have end parts 122 and 123 adjacent and coupled. In the cavity 118, the insert part 120 comprises a cylinder 124 which has an axial hole 125. The annular front shoulder 126 of the cylinder 124 thus produced has two opposite and symmetrical portions of frustoconical front faces 127a and 127b, the vertex is located towards the front, as well as two opposite and symmetrical flats 128a and 128b more inclined than these frustoconical faces 127a and 1227b and produced in the latter. Thus, the annular front shoulder 125 is convex. In the axial hole 125 of the cylinder 124 is mounted a cylindrical lug 129 projecting forward. In the cavity 1 18, the insert part 121 comprises a cylinder 130 whose diameter is slightly greater than the diameter of the cylinder 124 of the insert part 120 and which has in its end part • 123 an axial recess 13 1 The front shoulder thus produced has a frustoconical front face 132 whose tip is directed towards the rear and of the same conicity as the frustoconical faces 127a and 127b of the insert part 120. Thus, the frustoconical front face 132 is concave . When the insert parts 120 and 121 are coupled and in the molding position, the lug 129 of the insert part 120 is engaged just in the recess 131 of the insert part 130 and the opposite frustoconical front faces 127a and 127b of the insert part 120 are in contact with or bear on two opposite parts of the frustoconical front face 132 of the insert part 121, while between the opposite and inclined flats 128a and 129a of the part of insert 120 and the other opposite parts of the insert part 121, located opposite the frustoconical front face 132, define opposite spaces and symmetrical 133 and 134, open laterally and inclined, whose volumes and shapes correspond to the lips 110 and 111 to be produced. Thus, the thickness of the spaces 133 and 134 increases from their circumferential end part to their middle part and their thickness increases from the lug 129 to their periphery, the spaces 133 and
134 présentant des surfaces cylindriques intérieures 135 et 136 présentant des arêtes circulaires d'extrémité opposées aux méplats. Comme le montre la figure 11, en vue de la réalisation du fil 112, le moule 114 comprend en outre une cavité allongée complémentaire cylindrique 137 qui communique avec la cavité principale 118. Dans cette cavité complémentaire 137 sont ménagées, en vue de la réalisation des parties annulaires en saillie 113 du fil 112, des parties annulaires en creux 138 qui présentent une face radiale 139 située du côté de la cavité 118 et une face tronconique 140 dont le sommet est opposée à la cavité 118. Ayant accolé les parties 115 et 116 du moule 114 et ayant placé les parties d'insert 120 et 121 dans la position décrite ci-dessus, on procède à l'injection d'une matière plastique dans les cavités 118 et 137. Ensuite, on extrait de la cavité 118, dans des sens opposés, les parties d'insert 120 et 121 et on procède à l'éjection du dispositif de scellé 101 ainsi réalisé. En conséquence de la forme des espaces 133 et 134 de l'insert 119, comme le montre plus précisément la figure 9, les lèvres d'accrochage 110 et 111 forment, dans le trou traversant 109, des coins inclinés espacés circonférentiellement et présentant des faces intérieures axiales cylindriques 110a et 111a résultant de la paroi cylindrique de l'ergot 129 et délimitant un passage cylindrique, des faces tronconiques avant 110b et 111b résultant de la face tronconique 132 de la partie d'insert 121 et des faces plates inclinées arrière 110c et 111c résultant des méplats inclinés 128a et 128b de l'insert 119, les faces intérieures axiales cylindriques 110a et 111a et les faces tronconiques 110b et 111b se rejoignant en formant des bords circulaires d'extrémité HOd et 11 ld. Ainsi, l'épaisseur des lèvres 110 et 111 augmente de leur partie d'extrémité circonférentielle à leur partie médiane et leur épaisseur augmente depuis leur extrémité jusqu'à la paroi du trou 109. Comme le montre plus précisément la figure 7, lorsque le fil 112 est engagé au travers du passage 109 de la pastille 102 pour constituer une boucle, chaque partie annulaire d'accrochage en saillie 113 du fil 112, obtenue dans les parties annulaires en creux 138 du moule 114, peut franchir en les déformant élastiquement les lèvres 110 et 111 ménagées dans le trou traversant 109 de la pastille 102, qui glissent sur sa surface tronconique 113a résultant de la surface 140 du moule 114, puis venir en avant des extrémités des lèvres d'accrochage 110 et 111, de façon à constituer un accrochage empêchant l'extraction du fil 112, sauf à rompre ce dernier. Dans cette position d'accrochage, les lèvres 110 et 111 sont orientées vers la face radiale 113b d'une partie annulaire en saillie 113 du fil 112. Leurs bords circulaires d'extrémité HOd et 111 d sont en contact avec la partie intérieure de cette face radiale 113b. Les faces cylindriques intérieures 110a et 111a des lèvres 110 et 111 enveloppent à faible distance la partie cylindrique correspondante du fil 112. Grâce à la structure de l'accrochage du fil 112 dans le trou 109 de la pastille 102, on peut assurer une résistance relativement importante à l'arrachement et à l'extraction du fil, la structure des lèvres 110 et 111 de la pastille 102 et la structure des parties annulaires d'accrochage 113 du fil 112 leur conférant une résistance pouvant être largement supérieure à la résistance à la rupture par traction du fil 112 dans ses parties cylindriques. La présente invention ne se limite pas aux exemples ci-dessus décrits. Bien des variantes sont possibles sans sortir du cadre défini par les revendications annexées. 134 having internal cylindrical surfaces 135 and 136 having circular end edges opposite the flats. As shown in FIG. 11, with a view to producing the wire 112, the mold 114 further comprises an elongated complementary cylindrical cavity 137 which communicates with the main cavity 118. In this complementary cavity 137 are provided, for the realization of the annular protruding parts 113 of the wire 112, hollow annular parts 138 which have a radial face 139 situated on the side of the cavity 118 and a frustoconical face 140 the apex of which is opposite to the cavity 118. Having joined the parts 115 and 116 of the mold 114 and having placed the insert parts 120 and 121 in the position described above, one proceeds to the injection of a plastic material into the cavities 118 and 137. Then, one extracts from the cavity 118, in opposite directions, the insert parts 120 and 121 and the sealing device 101 thus produced is ejected. As a consequence of the shape of the spaces 133 and 134 of the insert 119, as shown more precisely in FIG. 9, the hooking lips 110 and 111 form, in the through hole 109, inclined corners spaced circumferentially and having faces cylindrical axial interior 110a and 111a resulting from the cylindrical wall of the lug 129 and delimiting a cylindrical passage, frustoconical front faces 110b and 111b resulting from the frustoconical face 132 of the insert part 121 and rear inclined flat faces 110c and 111c resulting from the inclined flats 128a and 128b of the insert 119, the axial cylindrical inner faces 110a and 111a and the frustoconical faces 110b and 111b joining together to form circular end edges HOd and 11d. Thus, the thickness of the lips 110 and 111 increases by their part of circumferential end at their middle part and their thickness increases from their end to the wall of the hole 109. As shown more precisely in FIG. 7, when the wire 112 is engaged through the passage 109 of the patch 102 to constitute a loop, each annular projecting hooking part 113 of the wire 112, obtained in the hollow annular parts 138 of the mold 114, can pass by elastically deforming the lips 110 and 111 formed in the through hole 109 of the patch 102, which slide on its frustoconical surface 113a resulting from the surface 140 of the mold 114, then come in front of the ends of the hooking lips 110 and 111, so as to constitute a hooking preventing the extraction of the wire 112, except to break the latter . In this hooking position, the lips 110 and 111 are oriented towards the radial face 113b of an annular projecting part 113 of the wire 112. Their circular end edges HOd and 111 d are in contact with the internal part of this radial face 113b. The inner cylindrical faces 110a and 111a of the lips 110 and 111 envelop the corresponding cylindrical part of the wire 112 at a short distance. Thanks to the structure of the attachment of the wire 112 in the hole 109 of the patch 102, it is possible to ensure relatively resistance important when pulling out and extracting the wire, the structure of the lips 110 and 111 of the patch 102 and the structure of the annular attachment parts 113 of the wire 112 gives them a resistance which can be much greater than the resistance to tensile rupture of the wire 112 in its cylindrical parts. The present invention is not limited to the examples described above. Many variations are possible without departing from the scope defined by the appended claims.
