The transport of goods, which is carried out, for example, by standardized transport container, is likely to successively use various means of transport with between each phase waiting periods in generally poorly monitored areas: it is necessary to guarantee the receiver, either that the transport container was not opened during transport, or that if it has been opened the receiver has the means to realize it for himself in order to make all the reservations use on the goods received; this guarantee is currently provided by a tamper-evident device placed on the doors of the transport container.
Un dispositif d'inviolabilité est constitué, par exemple, d'un fil de fer formé de deux brins torsadés ensembles qui passent successivement à travers des trous pratiqués dans les portes et éventuellement dans leur chambranle ; les extrémités libres du fil de fer torsadé sont ensuite scellées entre elles par un sceau ; ce sceau est constitué initialement, par exemple, d'un dispositif de scellage réalisé dans une matière relativement malléable telle que du plomb et comportant un perçage ; les extrémités du fil de fer torsadé sont passées à travers le perçage et le dispositif de scellage est écrasé à l'aide d'une pince de manière que les torsades du fil de fer se bloquent dans la matière molle afin de former une boucle fermée qu'il faudra rompre pour ouvrir le conteneur de transport ; au moins l'un des mors comporte en creux la gravure du sceau qui sert à estampiller le dispositif de scellage afin qu'il puisse être facilement reconnu par le réceptionnaire.A tamper-evident device consists, for example, of an iron wire formed by two strands twisted together which pass successively through holes made in the doors and possibly in their jamb; the free ends of the twisted wire are then sealed together with a seal; this seal initially consists, for example, of a sealing device made of a relatively malleable material such as lead and comprising a bore; the ends of the twisted wire are passed through the hole and the sealing device is crushed using pliers so that the twists of the wire are blocked in the soft material in order to form a closed loop that 'it will be necessary to break to open the transport container; at least one of the jaws has in hollow the engraving of the seal which is used to stamp the sealing device so that it can be easily recognized by the receiver.
Il est constaté de plus en plus fréquemment des vols dans les conteneurs de transport alors que le sceau d'origine
ne présente pas de traces d'effraction ; il apparaît qu'il est facile avec les moyens actuels de gravure de reproduire le sceau avec précision et à moindre coût ; de telle sorte que les voleurs peuvent détruire le sceau en place pour ouvrir le conteneur de transport et après avoir prélevé de la marchandise poser un nouveau sceau qui ne peut être discerné du sceau posé initialement sur le conteneur de transport.Thefts in transport containers are more and more frequently observed while the original seal shows no signs of break-in; it appears that it is easy with the current means of engraving to reproduce the seal with precision and at low cost; in such a way that thieves can destroy the seal in place to open the transport container and, after removing the goods, place a new seal which cannot be discerned from the seal initially placed on the transport container.

Figure 4 shows a perspective view of the tamper-evident container according to Figure 3 after closing.
La figure 5 représente une vue perspective d'un conteneur d'inviolabilité selon une variante de la version de la figure 3. Tout en conservant le dispositif d*' inviolabilité traditionnel 1 (fig.l) précédemment décrit utilisant un fil de fer torsadé 2 passant successivement par des trous 3, pratiqués dans la ou les portes 4 et si nécessaire leur chambranle et un sceau 5 reliant les deux extrémités libres 6 du fil de fer torsadé 2 pour réaliser une boucle 7, l'invention consiste à enfermer le sceau 5 dans un petit conteneur d'inviolabilité 8, comportant des moyens de passage du fil de fer torsadé 2 de la boucle 7 à travers des parois du conteneur d'inviolabilité ; le conteneur d'inviolabilité 8 est formé d'un corps creux 10 et d'un couvercle de fermeture 11 susceptible d'être verrouillé sur le corps creux 10 à l'aide de moyens de verrouillage composé, par exemple, des éléments 12,13,14,15, constituant un dispositif de verrouillage du couvercle de fermeture 11 présentant la particularité de se rompre en fin de verrouillage et au moins
un des éléments 13 (fig.2) qui le compose se trouvant séparé du conteneur d'inviolabilité 8, d'une part pour empêcher que le conteneur d'inviolabilité 8 puisse être ouvert sans qu'il apparaisse de traces sur la surface extérieure de ce dernier, d'autre part pour laisser à l'expéditeur un élément 13 susceptible d'être transmis au réceptionnaire permettant à ce dernier de vérifier que le conteneur d'inviolabilité 8 est bien celui qui a été posé au départ .FIG. 5 represents a perspective view of a tamper-evident container according to a variant of the version of FIG. 3. While retaining the traditional tamper-evident device 1 (fig.l) previously described using a twisted wire 2 passing successively through holes 3, made in the door (s) 4 and if necessary their jamb and a seal 5 connecting the two free ends 6 of the twisted wire 2 to form a loop 7, the invention consists in enclosing the seal 5 in a small tamper-evident container 8, comprising means for passing the twisted wire 2 of the loop 7 through the walls of the tamper-evident container; the tamper-evident container 8 is formed of a hollow body 10 and a closure cover 11 capable of being locked on the hollow body 10 using locking means composed, for example, of elements 12, 13 , 14,15, constituting a locking device for the closing cover 11 having the particularity of breaking at the end of locking and at least one of the elements 13 (fig. 2) which composes it being separated from the tamper-proof container 8, on the one hand to prevent the tamper-proof container 8 from being able to be opened without any traces appearing on the outer surface of the latter, on the other hand to leave to the sender an element 13 capable of being transmitted to the receiver allowing the latter to verify that the tamper-proof container 8 is indeed the one that was placed at the start.
Dans une version préférée de l'invention, le conteneur d'inviolabilité 8 est métallique et constitué d'un corps creux' 10 cylindrique de révolution constitué d'une paroi latérale tubulaire 16, fermée à une extrémité par un fond 17 de préférence plat et comportant à l'autre extrémité une ouverture totale 18 limitée par la paroi latérale tubulaire 16 ; le côté interne 19 de la paroi latérale tubulaire 16 du corps creux 10 comporte un filetage femelle 15 débouchant sur l'ouverture totale 18 ; le fond 17 est percé, par exemple, par au moins un trou 9 de petit diamètre et de préférence deux trous 9, pour laisser passer chacun au moins une extrémité libre 6 du fil de fer torsadé 2 ; le côté extérieur 20 de la paroi latérale tubulaire 16 comporte deux aplats parallèles 14, taillés dans l'épaisseur 21 de cette dernière et à une distance l'un de l'autre permettant l'utilisation d'une clé plate standard. Le couvercle de fermeture 11 est composé d'un disque 22 de révolution, autour d'un premier axe de symétrie 23, de diamètre 24 sensiblement égal au diamètre extérieur 25 du corps creux 10 et d'une épaisseur 26 suffisante pour pouvoir le tenir par la partie latérale 27, par exemple, avec une pince à prises multiples ; le disque 22 du couvercle de fermeture 11 comporte un côté externe 28 et un côté interne 29 ; le côté interne 29 du couvercle de fermeture 11 comporte une partie cylindrique de révolution 30, coaxiale avec le premier axe de symétrie 23, comportant latéralement un filetage mâle 12 venant se visser dans le filetage femelle 15 du corps creux 10 ; le côté externe 28 du couvercle de fermeture 11 comporte une tête de vissage 13 du couvercle de fermeture 11 dans le corps creux 10 ; la tête de vissage 13 est, par exemple, une tête hexagonale à six pans permettant d'utiliser, par exemple, une clé à pipe standard ; la tête de vissage 13 comporte un axe de symétrie confondu
avec le premier axe de symétrie 23 et elle est prolongée par un tronc de cône de révolution 31 ayant le premier axe de symétrie 23 comme axe de symétrie dont la grande base 32 est raccordée sur la tête de vissage 13 et dont la petite base est reliée au côté externe 28 du couvercle de fermeture 11 suivant un cercle de petit diamètre, centré sur le premier axe de symétrie 23, constituant une petite base de rupture 33 entourant une zone de rupture circulaire 34 (fig.2).In a preferred version of the invention, the tamper-evident container 8 is metallic and consists of a cylindrical hollow body 10 of revolution consisting of a tubular side wall 16, closed at one end by a bottom 17 preferably flat and comprising at the other end a total opening 18 limited by the tubular side wall 16; the internal side 19 of the tubular side wall 16 of the hollow body 10 has a female thread 15 leading to the total opening 18; the bottom 17 is pierced, for example, by at least one hole 9 of small diameter and preferably two holes 9, to let each pass at least one free end 6 of the twisted wire 2; the outer side 20 of the tubular side wall 16 comprises two parallel flats 14, cut in the thickness 21 of the latter and at a distance from each other allowing the use of a standard open-end wrench. The closing cover 11 is composed of a disc 22 of revolution, around a first axis of symmetry 23, of diameter 24 substantially equal to the outside diameter 25 of the hollow body 10 and of a thickness 26 sufficient to be able to hold it by the lateral part 27, for example, with a multi-grip pliers; the disc 22 of the closure cover 11 has an outer side 28 and an inner side 29; the internal side 29 of the closure cover 11 comprises a cylindrical part of revolution 30, coaxial with the first axis of symmetry 23, laterally comprising a male thread 12 coming to be screwed into the female thread 15 of the hollow body 10; the outer side 28 of the closure cover 11 has a screw head 13 of the closure cover 11 in the hollow body 10; the screwing head 13 is, for example, a hexagonal hexagon head making it possible to use, for example, a standard pipe wrench; the screwing head 13 has a coincident axis of symmetry with the first axis of symmetry 23 and it is extended by a truncated cone of revolution 31 having the first axis of symmetry 23 as an axis of symmetry whose large base 32 is connected to the screw head 13 and whose small base is connected on the external side 28 of the closure cover 11 in a circle of small diameter, centered on the first axis of symmetry 23, constituting a small rupture base 33 surrounding a circular rupture zone 34 (fig.2).
La mise en place du conteneur d'inviolabilité 8 (fig.l) se fait après avoir passé le fil de fer torsadé 2 dans les trous- 3 des portes 4 à rendre inviolable, comme cela est fait actuellement, en introduisant chacune des deux extrémités 6 du fil de fer torsadé 2 à travers les trous 9 du fond 17 du corps creux 10 dans le sens allant de l'extérieur vers l'intérieur jusqu'à ce que les deux extrémités 6 du fil de fer torsadé 2 ressortent par l'ouverture totale 18 ; ce qui permet de poser le sceau 5 de préférence au voisinage des extrémités 6 du fil de fer torsadé 2 pour constituer la boucle 7 précédemment décrite ; en faisant coulisser le fil de fer torsadé 2 dans les trous 9 du fond du corps creux 10 dans le sens allant de l'intérieur vers l'extérieur, le sceau 5 vient se loger à l'intérieur du corps creux 10 ; le couvercle de fermeture 11 est ensuite vissé grâce au filetage mâle 12 qui se visse dans le filetage femelle 15 du corps creux 10 jusqu'à ce que la face interne 29 'du disque 22 vienne en appui sur le bord 35 de l'ouverture totale 18, puis il est serré, d'une part en bloquant en rotation le corps ceux 10 avec une clé plate emmanchée sur les aplats 14 et, d'autre part, en serrant le couvercle de fermeture 11 avec, par exemple, une clé à pipe emboîtée sur la tête de vissage 13 jusqu'à ce que la tête de vissage 13 se sépare du disque 22 du couvercle de fermeture 11 par rupture du métal au niveau du cercle constituant la petite base de rupture 33 de la tête de vissage 13. Dans ces conditions, le couvercle de fermeture 11 (fig.2) présente à l'extérieur la face extérieure 28 du disque 22 avec en son centre une zone de rupture circulaire 34 dont la conformation de la surface s'adapte à celle de la petite base de rupture 33 ; le dévissage du couvercle de fermeture 11 ne peut se faire qu'en créant des points
d'accrochage sur le couvercle de fermeture 11 qui laissent obligatoirement des traces dans le métal et permet de détecter si le conteneur d'inviolabilité 8 a été ouvert frauduleusement ; ces points d'accrochage peuvent être faits, par exemple, en serrant la partie latérale 27 du couvercle de fermeture 11 avec une pince à prises multiples et en utilisant une clé plate emboîtée sur les aplats du corps creux pour opérer le dévissage du couvercle de fermeture 11 ; c'est aussi la méthode qui peut être utilisée par le réceptionnaire pour ouvrir le conteneur d'inviolabilité 8 pour vérifier que le sceau 5 (fig.l) est intact.The establishment of the tamper-proof container 8 (fig.l) is done after passing the twisted wire 2 in the holes- 3 of the doors 4 to be made tamper-proof, as is currently done, by introducing each of the two ends 6 of the twisted wire 2 through the holes 9 in the bottom 17 of the hollow body 10 in the direction going from the outside towards the inside until the two ends 6 of the twisted wire 2 come out through the total opening 18; which allows to place the seal 5 preferably in the vicinity of the ends 6 of the twisted wire 2 to form the loop 7 previously described; by sliding the twisted wire 2 in the holes 9 in the bottom of the hollow body 10 in the direction from the inside to the outside, the seal 5 is housed inside the hollow body 10; the closure cover 11 is then screwed using the male thread 12 which is screwed into the female thread 15 of the hollow body 10 until the internal face 29 ′ of the disc 22 comes to bear on the edge 35 of the total opening 18, then it is tightened, on the one hand by blocking in rotation the body those 10 with a flat key fitted on the flat areas 14 and, on the other hand, by tightening the closing cover 11 with, for example, a wrench pipe fitted onto the screwing head 13 until the screwing head 13 separates from the disc 22 of the closure cover 11 by breaking the metal at the level of the circle constituting the small breaking base 33 of the screwing head 13. Under these conditions, the closing cover 11 (fig. 2) has on the outside the outer face 28 of the disc 22 with at its center a circular rupture zone 34 whose conformation of the surface adapts to that of the small rupture base 33; unscrewing the closing cover 11 can only be done by creating points hooking on the closure cover 11 which necessarily leave traces in the metal and makes it possible to detect whether the tamper-evident container 8 has been fraudulently opened; these attachment points can be made, for example, by tightening the lateral part 27 of the closure cover 11 with a pliers with multiple grips and by using a flat key fitted on the flat surfaces of the hollow body to operate the unscrewing of the closure cover 11; it is also the method that can be used by the receiver to open the tamper-proof container 8 to verify that the seal 5 (fig.l) is intact.
Le métal constituant le couvercle de fermeture 11 (fig.l) est de préférence un alliage de faible dureté et obtenu par coulage et solidification de manière à avoir une structure cristalline ayant une faible élasticité et susceptible de se briser brutalement sous l'effet de la contrainte de torsion appliquée au moment du verrouillage du couvercle de fermeture 11 sur le corps creux 10 ; dans ces conditions, il est possible de contrôler que la zone de rupture circulaire 34 du couvercle de fermeture 11 a une conformation dans laquelle vient s'emboîter la petite base de rupture 33 de la tête de vissage 13 afin de vérifier que le couvercle de fermeture 11 n'a pas été changé. L'alliage constituant le couvercle de fermeture 11 peut être un alliage de cuivre et d'aluminium.The metal constituting the closure cover 11 (fig.l) is preferably an alloy of low hardness and obtained by casting and solidification so as to have a crystalline structure having a low elasticity and liable to break suddenly under the effect of the torsional stress applied when locking the closure cover 11 on the hollow body 10; under these conditions, it is possible to check that the circular rupture zone 34 of the closure cover 11 has a conformation in which the small rupture base 33 of the screw head 13 fits in order to verify that the closure cover It has not been changed. The alloy constituting the closure cover 11 can be an alloy of copper and aluminum.
Le métal constituant le corps creux 10 est de préférence un acier inoxydable présentant de bonnes caractéristiques mécaniques pour être éventuellement réutilisable.The metal constituting the hollow body 10 is preferably a stainless steel having good mechanical characteristics to be optionally reusable.
Il est possible d'identifier chaque corps creux 10 et chaque couvercle de fermeture 11 par rapport à la composition de l'alliage métallique qui le constitue et qui est unique pour une coulée déterminée ; cela peut être réalisé, par exemple, en donnant un premier numéro 36, 37, à chaque barre métallique ayant servi à faire un corps creux 10 ou un couvercle de fermeture 11 et en donnant un numéro d'ordre 38, 39 à chaque pièce effectuée dans une barre métallique ; ces deux numéros, 36 et 38 pour le corps creux 10 d'une part, et 37 et 39 pour le couvercle de fermeture 11 d'autre part, peuvent être reportés sur la pièce en fin d'usinage ; en ce qui concerne le couvercle de fermeture 11 il est souhaitable
que les numéros 37 et 39 figurent sur le disque 22 et sur la tête de vissage 13 ; le premier numéro 36, 37 est aussi reporté sur un échantillon de la barre métallique usinée qui est ensuite classé dans une réserve ; ces numéros 36, 37, 38, 39 sont transmis directement au réceptionnaire ainsi que la tête de vissage 13.It is possible to identify each hollow body 10 and each closure cover 11 with respect to the composition of the metal alloy which constitutes it and which is unique for a specific casting; this can be achieved, for example, by giving a first number 36, 37, to each metal bar used to make a hollow body 10 or a closure cover 11 and by giving a serial number 38, 39 to each piece made in a metal bar; these two numbers, 36 and 38 for the hollow body 10 on the one hand, and 37 and 39 for the closure cover 11 on the other hand, can be transferred to the part at the end of machining; with regard to the closing cover 11 it is desirable that the numbers 37 and 39 appear on the disc 22 and on the screwing head 13; the first number 36, 37 is also transferred to a sample of the machined metal bar which is then classified in a reserve; these numbers 36, 37, 38, 39 are transmitted directly to the receiver as well as the screwing head 13.
En cas de litige, il est alors possible de contrôler que le métal de l'échantillon gardé en réserve a bien la même composition que le métal du corps creux 10 et/ou du couvercle de fermeture 11 objet du litige ; si la composition n'est pas la même, cela veut dire que le conteneur d'inviolabilité 8 a été remplacé par un conteneur d'origine frauduleuse.In the event of a dispute, it is then possible to check that the metal of the sample kept in reserve has the same composition as the metal of the hollow body 10 and / or of the closure cover 11 which is the subject of the dispute; if the composition is not the same, this means that the tamper-evident container 8 has been replaced by a container of fraudulent origin.
Afin de rendre plus complexe le démontage et/ou l'usinage frauduleux du corps creux 10 et du couvercle de fermeture 11, il est possible d'utiliser des pas de vissage non standardisés comme, par exemple, un pas à gauche de onze soixante quatrièmes de pouce qui exige la possession d'outillage presque impossible à trouver. Le corps creux 10 du conteneur d'inviolabilité 8 peut être réutilisé pour un autre transport .In order to make the disassembly and / or fraudulent machining of the hollow body 10 and of the closure cover 11 more complex, it is possible to use non-standardized screwing steps such as, for example, a step to the left of eleven sixty fourth inch which requires the possession of tools almost impossible to find. The hollow body 10 of the tamper-evident container 8 can be reused for another transport.
Dans une autre version de l'invention, le corps creux 40 (fig.3) ne comporte pas de petits trous permettant de faire passer le fil de fer torsadé 41 ; en contrepartie la partie cylindrique de révolution 42 supportant sur sa face latérale extérieure le filetage mâle 43 du ' couvercle de fermeture 44 est une portion de tube, constituant une paroi latérale 45 dont la face intérieure 46 délimite un volume libre 55 cylindrique de révolution avec des génératrices perpendiculaires au plan de la face interne 47 du disque 48 appartenant au couvercle de fermeture 44 qui limite le volume libre 55 à une première extrémité, la deuxième extrémité 49 étant ouverte ; ce volume libre 55 a des dimensions permettant de recevoir un sceau 50 fixé sur les fils de fer torsadés 41 pour former une boucle ; cette paroi latérale 45 comporte sur toute sa hauteur au moins deux fentes 51,52 de préférence rectilignes perpendiculaires au disque 48 du couvercle de fermeture 44 ; ces fentes 51 et 52 commencent au niveau de la face interne 47 du couvercle de fermeture 44 et débouchent au niveau de la deuxième extrémité 49 ; les fentes 51 et 52 sont de préférence placées en des positions
diamétralement opposées et leur largeur permet d'y placer au moins un fil de fer torsadé 41. Un tel conteneur d'inviolabilité 53 (fig.4) peut être placé sur la boucle d'inviolabilité 54 après la pose de sceau 50 (fig.3) ; le sceau 50 est introduit dans le volume libre 55 et les fils de fer torsadés 41 sont passés à travers les fentes 51 et 52 pour se positionner sensiblement radialement à la paroi interne 47 du disque 48 ; lors du vissage du couvercle 44 suivant la description précédente les fils de fer torsadés 41 (fig.4) sont coincés entre le disque 48 du couvercle de fermeture 44 et le sommet de l'ouverture totale du corps creux 40 et viennent s'encastrer dans la face intérieure 47 du couvercle de fermeture 44 lors du serrage de ce dernier sur le corps creux 40. Le sceau 50 (fig.3) ne supporte plus de contraintes et donc ne peut être détruit par inadvertance. Dans une variante de l'invention, dans le cas où l'incrustation des fils de fer torsadés 41 ne pourrait se faire à cause, par exemple, d'une trop grande dureté des matériaux utilisés, ce qui pourrait rendre la force de serrage aléatoire, les fentes 51 et 52 sont prolongées par des sillons 56 creusés sur la face interne 59 du disque 60 et débouchant sur le bord latéral 57 de ce dernier de manière que les fils de fer torsadés 61 puissent y être logés avant serrage du couvercle de fermeture 58 sur le corps creux 40 du conteneur d'inviolabilité 62. Les conteneurs d" inviolabilité 53 et 62 ainsi décrits peuvent être posés à tout moment en cours de transport pendant, par exemple, certaines phases spécifiques à haut risque et enlevé avant la livraison finale .
In another version of the invention, the hollow body 40 (fig.3) does not have small holes for passing the twisted wire 41; in return the cylindrical part of revolution 42 supporting on its external lateral face the male thread 43 of the 'closing cover 44 is a portion of tube, constituting a lateral wall 45 whose internal face 46 defines a free volume 55 cylindrical of revolution with generatrices perpendicular to the plane of the internal face 47 of the disc 48 belonging to the closure cover 44 which limits the free volume 55 at a first end, the second end 49 being open; this free volume 55 has dimensions making it possible to receive a seal 50 fixed on the twisted wires 41 to form a loop; this side wall 45 comprises over its entire height at least two slots 51, 52 preferably rectilinear perpendicular to the disc 48 of the closure cover 44; these slots 51 and 52 start at the internal face 47 of the closure cover 44 and open at the second end 49; the slots 51 and 52 are preferably placed in positions diametrically opposite and their width allows to place at least one twisted wire 41. Such a tamper-evident container 53 (fig.4) can be placed on the tamper-evident loop 54 after the installation of seal 50 (fig. 3); the seal 50 is introduced into the free volume 55 and the twisted wires 41 are passed through the slots 51 and 52 to position themselves substantially radially to the internal wall 47 of the disc 48; during the screwing of the cover 44 according to the preceding description the twisted iron wires 41 (fig. 4) are wedged between the disc 48 of the closure cover 44 and the top of the total opening of the hollow body 40 and come to be embedded in the inner face 47 of the closure cover 44 when the latter is tightened on the hollow body 40. The seal 50 (FIG. 3) can no longer bear stresses and therefore cannot be destroyed inadvertently. In a variant of the invention, in the case where the inlaying of the twisted wires 41 cannot be done because, for example, of too great a hardness of the materials used, which could make the clamping force random , the slots 51 and 52 are extended by grooves 56 hollowed out on the internal face 59 of the disc 60 and opening onto the lateral edge 57 of the latter so that the twisted wires 61 can be accommodated there before tightening the closure cover 58 on the hollow body 40 of the tamper-evident container 62. The tamper-evident containers 53 and 62 thus described can be placed at any time during transport during, for example, certain specific high-risk phases and removed before final delivery .
