Definitions
- the present invention relates to a tamper-proof seal intended in particular for containers of all types, such as wagons, trailers, tanks, sea containers or the like.
- Seals are already known, such as that described in French patent application FR-A-2 630 772, consisting of a male part snapping into a female part, the joining of these two parts made of metal being ensured by a U-shaped spring secured to the end of the male part, the branches of which, after introduction into the female part, are deployed in an internal cavity formed in the latter.
- tamper-evident seals are also known, such as those described in patent application EP-A-0 417 022, in the name of the applicant. These seals consist of a block of transparent plastic material in which is buried the end of a steel cable, the other end comprising a harpoon-type fixing means which is introduced into an orifice of suitable shape practiced in said block.
- Breaking in by extracting the cable from the block results in deterioration of the means for holding the end of the cable in the block, and this deterioration is visible from the outside due to the transparency of the material used to make said block. .
- the present invention overcomes this drawback by providing a tamper-proof seal with a lower manufacturing cost.
- the seal object of the present invention comprises two parts, a male part and a female part.
- the male part of the seal according to the invention consists of a rod, one end of which is in the form of a harpoon and the other of which has a locking means.
- This rod is made of a plastic material which has the particularity of not being able to be glued after sectioning, such as polypropylene.
- the female part of the seal according to the invention is a block of transparent plastic material in which is formed an orifice extended by a cavity capable of receiving and holding the harpoon-shaped end of the male part and preventing it from to get out of it other than by damaging said harpoon-shaped part or by breaking the rod.
- said rod is not of round section, but has a flat and the cavity of the female block is of the same section, so that said rod can be introduced into said female block only one way and that it cannot rotate there, which prevents its extraction.
- the flat part of the rod can advantageously be used as a support for a number which can be transferred to the female block, preventing any falsification, the number of the female block having to correspond to that read by transparency on the rod.
- the number written on the female block can be by hot stamping inside, which gives it the advantage of being inaccessible and therefore tamper-proof.
- the seal according to the invention makes it possible, for example, to connect the two doors of a container each comprising a tab pierced with an orifice, the two tabs and the two orifices being arranged facing each other: the male rod is introduced into these two orifices and its end is pressed into the female block, so that the male rod cannot be extracted from said orifices of said legs, being blocked on one side by the female block and on the other by the blocking means, which may be constituted an end bulge which serves as a stop.
- the seal 1 according to the invention comprises a female part 2 and a male part 3.
- the male part 3 consists of a plastic rod 30 having at one end a bulge 31 and at the other end 32 two fins 33 and 34 in the form of a harpoon. These fins 33 and 34 are flexible enough to be able, under the effect of bilateral pressure, to fall back into housings, respectively 33 ′ and 34 ′, constituted by a thinning of the rod 30, so as to adopt the latter's template over the rest of its length. By cons these fins 33 and 34 are breakable at the spacing.
- the female part 2 consists of a parallelepipedal block 20 of transparent plastic material in one face of which is formed an opening 21 extended by a cavity 22 to the dimensions of the rod 30, and the end portion 23 of which has a shape adapted to accommodate the the harpoon-shaped end 32 of the rod 30, having for this purpose two facing edges 24 and 25, substantially perpendicular to the axis of the tubular cavity 22.
- the seal comprises a second means of viewing an attempted break-in, consisting firstly of two lugs 26 ′ and 27 ′ arranged in two facing chambers 26 and 27 located substantially in the middle of the cavity 22, the lugs 26 ′, 27 ′ extending into the cavity 22, and on the other hand by a peripheral notch 35 formed in the rod 30 at a distance from its end 32 such that, when the rod 30 is introduced into the cavity 22, the ends lugs 26 ′ and 27 ′ are positioned in the peripheral notch 35, an attempt to withdraw the rod 30 from the block 20 resulting in deterioration, also visible, of the lugs 26 ′ and 27 ′.
- the block 20 has a location 28 on which a number can be affixed, and the rod 30 has a flat 36 on which the same number can be affixed, this flat 36 being visible by transparency when the rod 30 is introduced into the cavity 22.
- the flat 36 has another function, that of preventing the rod 30 from rotating in the cavity 22, which is not of round section but also comprises a flat (not visible in the figure).
- a non-angular widening 29 is also made in the cavity 22 between the housings 26 and 27 and the opening 21, in order to allow the temporary attachment of the male part 3 and the female part 2, by partial introduction of the end 21 of the rod 30 in the cavity 22, the fins 33 and 34 then deploying in the enlargement 29.
- the rod 30 is thus temporarily blocked in the block 20, but can be extracted therefrom, because the enlargement 29 is rounded, the fins 33 and 34 being able to enter the housings 33 ′ and 34 ′ during the extraction.
- the male part 3 and the female part 2 which bear the same number can be paired and packaged in this way.
- the female part 2 has two openings 210 and 211, formed in two opposite sides of a parallelepipedal block 200 and offset, each of these openings 210 and 211 being extended by a cavity, respectively 220 and 221, similar to the cavity 22 of the block 20 described above.
- the male part 3 consists of two rods 300 and 301 similar to the rod 30 and which are assembled to the block 200 in the same way as the rod 30 to the block 20.
- This other embodiment of the seal according to the invention makes it possible in particular to seal the doors of a container provided with a seal support such as that described in French patent application 91/05438 in the name of the applicant.
- the female part 2 can have two openings 212 and 213, made side by side on the same side of a block 201 and each opening on a cavity, respectively 222 and 223 , while the male part 3 consists of a cable 5 at each end of which is attached a part 50 similar to the front part of the rod 30 of Figure 1.
- This cable 5, which is relatively long, allows in particular to seal the doors of a container or a semi-trailer by passing it successively through several orifices before introducing the ends into the block 201.
- a seal support 6 such as that described in French patent application 91/05438, comprising on the one hand two tabs 60 and 61 arranged parallel one with respect to the 'other and secured to the lower rear crossmember 66 of a container or a trailer, each being pierced by two orifices, respectively 600, 601 and 610, 611, and further comprising a flat iron 62 secured to a leaf 63 of the container to be sealed and a flat iron 64 secured to the other leaf 65, these flat irons each comprising two orifices, respectively 620, 621 and 640, 641.
- the flat iron 62, respectively 64 is parallel to the tab 60, respectively 61, and the orifices 620, 621, 640 and 641 are opposite respectively the orifices 600, 601, 610 and 611.
- the seal making it possible to join the two legs 60 and 61 consists of the association of the block 200 shown in FIG. 2 with the male part 3, shown in FIG. 3.
- the block 200 is placed between the two legs 60 and 61, the opening 210 facing the orifice 600, and the opening 211 facing the orifice 611.
- the end 50 of the cable 5 is successively introduced into the orifices 620 and 600 then into the opening 210 to be blocked in the cavity 220.
- the other end 50 of the cable 5 is successively introduced into the orifices 621, 601, 610, 640, 641, 611 and finally blocked in the cavity 221.
- the cable 5 it is not necessary for the cable 5 to have two ends 50 and 51 which can be snapped into the female block 200, one of the two being able to be crimped from the original in said female block.

Description
La présente invention a pour objet un scellé infalsifiable destiné notamment aux conteneurs de tous types, tels que wagons, remorques, citernes, conteneurs maritimes ou analogues.The present invention relates to a tamper-proof seal intended in particular for containers of all types, such as wagons, trailers, tanks, sea containers or the like.
On connaît déjà des scellés, tels celui décrit dans la demande de brevet français FR-A-2 630 772, constitués d'une pièce mâle s'encliquetant dans une pièce femelle, la solidarisation de ces deux pièces réalisées en métal étant assurée par un ressort en U solidaire de l'extrémité de la pièce mâle dont les branches, après l'introduction dans la pièce femelle, se déploient dans une cavité intérieure ménagée dans cette dernière.Seals are already known, such as that described in French patent application FR-A-2 630 772, consisting of a male part snapping into a female part, the joining of these two parts made of metal being ensured by a U-shaped spring secured to the end of the male part, the branches of which, after introduction into the female part, are deployed in an internal cavity formed in the latter.
Ce type de scellé présente toutefois l'inconvénient de ne pas être totalement infalsifiable : il est en effet possible, avant que la pièce mâle soit introduite dans la pièce femelle, d'en couper l'extrémité servant à l'encliquetage puis de resolidariser les morceaux au moyen de colle, enfin d'assembler pièce mâle et pièce femelle en donnant l'illusion d'un scellé inviolé, la reconstitution au moyen de colle n'étant pas visible du fait de l'opacité de la pièce femelle. Il suffit ensuite de décoller puis de recoller les morceaux au gré d'intrusions dans le conteneur apparemment protégé.This type of seal, however, has the drawback of not being totally tamper-proof: it is indeed possible, before the male part is introduced into the female part, to cut off the end used for snap-fastening and then to re-join the pieces by means of glue, finally to assemble male part and female part by giving the illusion of a seal inviolate, the reconstitution by means of glue not being visible due to the opacity of the female part. Then just take off and then glue the pieces according to intrusions in the apparently protected container.
On connaît également d'autres scellés infalsifiables, tels ceux décrits dans la demande de brevet EP-A-0 417 022, au nom du demandeur. Ces scellés sont constitués d'un bloc de matière plastique transparente dans lequel est noyée l'extrémité d'un câble en acier, l'autre extrémité comportant un moyen de fixation de type harpon que l'on introduit dans un orifice de forme adaptée pratiqué dans ledit bloc.Other tamper-evident seals are also known, such as those described in patent application EP-A-0 417 022, in the name of the applicant. These seals consist of a block of transparent plastic material in which is buried the end of a steel cable, the other end comprising a harpoon-type fixing means which is introduced into an orifice of suitable shape practiced in said block.
Une effraction par extraction du câble hors du bloc a pour conséquence la détérioration des moyens de maintien de l'extrémité du câble dans le bloc, et cette détérioration est visible de l'extérieur du fait de la transparence de la matière employée pour réaliser ledit bloc.Breaking in by extracting the cable from the block results in deterioration of the means for holding the end of the cable in the block, and this deterioration is visible from the outside due to the transparency of the material used to make said block. .
Ces scellés, qui sont réellement infalsifiables, présentent néanmoins l'inconvénient d'être d'un coût de fabrication relativement élevé.These seals, which are truly tamper-proof, nevertheless have the disadvantage of being of relatively high manufacturing cost.
La présente invention permet de remédier à cet inconvénient en proposant un scellé infalsifiable d'un coût de fabrication moindre.The present invention overcomes this drawback by providing a tamper-proof seal with a lower manufacturing cost.
Le scellé objet de la présente invention comporte deux parties, une partie mâle et une partie femelle.The seal object of the present invention comprises two parts, a male part and a female part.
La partie mâle du scellé selon l'invention est constituée d'une tige dont l'une des extrémités est en forme de harpon et dont l'autre présente un moyen de blocage. Cette tige est réalisée en une matière plastique qui présente la particularité de ne pas pouvoir être recollée après sectionnement, telle qu'un polypropylène.The male part of the seal according to the invention consists of a rod, one end of which is in the form of a harpoon and the other of which has a locking means. This rod is made of a plastic material which has the particularity of not being able to be glued after sectioning, such as polypropylene.
La partie femelle du scellé selon l'invention est un bloc de matière plastique transparente dans lequel est pratiqué un orifice prolongé par une cavité apte à recevoir et à maintenir l'extrémité en forme de harpon de la partie mâle et à l'empêcher d'en sortir autrement qu'en détériorant ladite partie en forme de harpon ou en cassant la tige.The female part of the seal according to the invention is a block of transparent plastic material in which is formed an orifice extended by a cavity capable of receiving and holding the harpoon-shaped end of the male part and preventing it from to get out of it other than by damaging said harpoon-shaped part or by breaking the rod.
Conformément à l'invention, ladite tige n'est pas de section ronde, mais comporte un méplat et la cavité du bloc femelle est de même section, de manière que ladite tige ne puisse être introduite dans ledit bloc femelle que d'une seule façon et qu'elle ne puisse y tourner, ce qui empêche son extraction.According to the invention, said rod is not of round section, but has a flat and the cavity of the female block is of the same section, so that said rod can be introduced into said female block only one way and that it cannot rotate there, which prevents its extraction.
Le méplat de la tige peut avantageusement être utilisé comme support d'un numéro qui peut être reporté sur le bloc femelle, interdisant toute falsification, le numéro du bloc femelle devant correspondre à celui lu par transparence sur la tige.The flat part of the rod can advantageously be used as a support for a number which can be transferred to the female block, preventing any falsification, the number of the female block having to correspond to that read by transparency on the rod.
Le numéro inscrit sur le bloc femelle peut l'être par marquage à chaud à l'intérieur, ce qui lui confère l'avantage d'être inaccessible, donc infalsifiable.The number written on the female block can be by hot stamping inside, which gives it the advantage of being inaccessible and therefore tamper-proof.
Le scellé selon l'invention permet de relier par exemple les deux portes d'un container comportant chacune une patte percée d'un orifice, les deux pattes et les deux orifices étant disposés en regard : la tige mâle est introduite dans ces deux orifices et son extrémité est enfoncée dans le-bloc femelle, en sorte que la tige mâle ne peut être extraite desdits orifices desdites pattes, étant bloquée d'un côté par le bloc femelle et de l'autre par le moyen de blocage, qui peut être constitué d'un renflement d'extrémité qui sert de butée.The seal according to the invention makes it possible, for example, to connect the two doors of a container each comprising a tab pierced with an orifice, the two tabs and the two orifices being arranged facing each other: the male rod is introduced into these two orifices and its end is pressed into the female block, so that the male rod cannot be extracted from said orifices of said legs, being blocked on one side by the female block and on the other by the blocking means, which may be constituted an end bulge which serves as a stop.
Le prix de revient d'un tel scellé est inférieur à celui des scellés connus, puisqu'il ne nécessite que la fabrication par moulage du bloc femelle d'une part et de la tige mâle d'autre part. Il n'est donc pas nécessaire de réaliser des opérations d'usinage et de sertissage, comme c'est le cas pour les scellés connus.The cost price of such a seal is lower than that of known seals, since it only requires the manufacture by molding of the female block on the one hand and of the male rod on the other hand. It is therefore not necessary to carry out machining and crimping operations, as is the case for known seals.
Les avantages et les caractéristiques de la présente invention ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente quelques modes de réalisation non limitatifs.The advantages and characteristics of the present invention will emerge more clearly from the description which follows and which refers to the appended drawing, which represents some non-limiting embodiments.

Si on se réfère d'abord à la figure 1 on peut voir que le scellé 1 selon l'invention comporte une partie femelle 2 et une partie mâle 3.If we refer first to FIG. 1, it can be seen that the seal 1 according to the invention comprises a
La partie mâle 3 est constituée d'une tige 30 en matière plastique présentant à une extrémité un renflement 31 et à l'autre extrémité 32 deux ailettes 33 et 34 en forme de harpon. Ces ailettes 33 et 34 sont suffisamment souples pour pouvoir, sous l'effet d'une pression bilatérale, se rabattre dans des logements, respectivement 33′ et 34′, constitués par un amincissement de la tige 30, de manière à adopter le gabarit de cette dernière sur le reste de sa longueur. Par contre ces ailettes 33 et 34 sont cassables à l'écartement.The
La pièce femelle 2 est constituée d'un bloc parallélépipédique 20 en matière plastique transparente dans une face duquel est pratiquée une ouverture 21 prolongée par une cavité 22 aux dimensions de la tige 30, et dont la partie extrême 23 présente une forme adaptée à loger l'extrémité 32 en forme de harpon de la tige 30, présentant à cet effet deux bords 24 et 25 en regard, sensiblement perpendiculaires à l'axe de la cavité tubulaire 22.The
Ainsi lorsque la tige 30 est introduite dans la cavité 22 par son extrémité 32, les ailettes 33 et 34 se replient dans les logements 33′ et 34′ pour se déployer dans l'extrémité 23, venant en appui sur les bords 24 et 25 en cas de tentative de retrait de la tige 30, et se détériorant de façon visible si l'on poursuit ladite tentative de retrait.Thus when the
Le scellé comporte un second moyen de visualisation d'une tentative d'effraction, constitué d'une part par deux ergots 26′ et 27′ disposés dans deux chambres 26 et 27 en regard situées sensiblement au milieu de la cavité 22, les ergots 26′, 27′ se prolongeant jusque dans la cavité 22, et d'autre part par une entaille périphérique 35 pratiquée dans la tige 30 à une distance de son extrémité 32 telle que, lorsque la tige 30 est introduite dans la cavité 22, les extrémités des ergots 26′ et 27′ se positionnent dans l'entaille périphérique 35, une tentative de retrait de la tige 30 du bloc 20 ayant pour conséquence la détérioration, également visible, des ergots 26′ et 27′.The seal comprises a second means of viewing an attempted break-in, consisting firstly of two
Le bloc 20 comporte un emplacement 28 sur lequel peut être apposé un numéro, et la tige 30 comporte un méplat 36 sur lequel peut être apposé le même numéro, ce méplat 36 étant visible par transparence lorsque la tige 30 est introduite dans la cavité 22.The
Le méplat 36 a une autre fonction, celle d'empêcher la tige 30 de tourner dans la cavité 22, laquelle n'est pas de section ronde mais comporte également un méplat (non visible sur la figure).The flat 36 has another function, that of preventing the
Un élargissement 29 non anguleux est également pratiqué dans la cavité 22 entre les logements 26 et 27 et l'ouverture 21, en vue de permettre la solidarisation provisoire de la pièce mâle 3 et de la pièce femelle 2, par introduction partielle de l'extrémité 21 de la tige 30 dans la cavité 22, les ailettes 33 et 34 se déployant alors dans l'élargissement 29.A
La tige 30 est ainsi provisoirement bloquée dans le bloc 20, mais peut en être extraite, du fait que l'élargissement 29 est arrondi, les ailettes 33 et 34 pouvant rentrer dans les logements 33′ et 34′ lors de l'extraction.The
La pièce mâle 3 et la pièce femelle 2 qui portent le même numéro peuvent être appairées et conditionnées de cette façon.The
Si on se réfère maintenant à la figure 2 on peut voir que dans un autre mode de réalisation du scellé selon l'invention, la pièce femelle 2 comporte deux ouvertures 210 et 211, pratiquées dans deux côtés opposés d'un bloc parallélépipédique 200 et de façon décalée, chacune de ces ouvertures 210 et 211 étant prolongée par une cavité, respectivement 220 et 221, semblable à la cavité 22 du bloc 20 décrit précédemment.Referring now to Figure 2 we can see that in another embodiment of the seal according to the invention, the
La partie mâle 3 est constituée de deux tiges 300 et 301 semblables à la tige 30 et qui s'assemblent au bloc 200 de la même manière que la tige 30 au bloc 20.The
Cet autre mode de réalisation du scellé selon l'invention permet notamment de sceller les portes d'un container munies d'un support de scellé tel que celui décrit dans la demande de brevet français 91/05438 au nom du demandeur.This other embodiment of the seal according to the invention makes it possible in particular to seal the doors of a container provided with a seal support such as that described in French patent application 91/05438 in the name of the applicant.
Si on se réfère à la figure 3 on peut voir que la pièce femelle 2 peut comporter deux ouvertures 212 et 213, pratiquées côte-à-côte sur un même côté d'un bloc 201 et ouvrant chacune sur une cavité, respectivement 222 et 223, tandis que la pièce mâle 3 est constituée d'un câble 5 à chaque extrémité duquel est solidarisée une pièce 50 semblable à la partie antérieure de la tige 30 de la figure 1. Ce câble 5, qui est de relativement grande longueur, permet notamment de sceller les portes d'un container ou d'un semi-remorque en le faisant passer successivement dans plusieurs orifices avant d'en introduire les extrémités dans le bloc 201.If we refer to Figure 3 we can see that the
Si on se réfère maintenant à la figure 4 on peut voir un support de scellé 6 tel que celui décrit dans la demande de brevet français 91/05438, comportant d'une part deux pattes 60 et 61 disposées parallèlement l'une par rapport à l'autre et solidarisées à la traverse arrière basse 66 d'un conteneur ou d'une remorque, chacune étant percée de deux orifices, respectivement 600, 601 et 610, 611, et comportant d'autre part un fer plat 62 solidarisé à un battant 63 du contenant à sceller et un fer plat 64 solidarisé à l'autre battant 65, ces fers plats comportant chacun deux orifices, respectivement 620, 621 et 640, 641. Lorsque les battants sont fermés le fer plat 62, respectivement 64 est parallèle à la patte 60, respectivement 61, et les orifices 620, 621, 640 et 641 sont en regard respectivement des orifices 600, 601, 610 et 611.If we now refer to FIG. 4, we can see a
Le scellé permettant de réunir les deux pattes 60 et 61 est constitué de l'association du bloc 200 représenté à la figure 2 avec la pièce mâle 3, représentée à la figure 3.The seal making it possible to join the two
Le bloc 200 est placé entre les deux pattes 60 et 61, l'ouverture 210 étant en regard de l'orifice 600, et l'ouverture 211 en regard de l'orifice 611.The
L'extrémité 50 du câble 5 est introduite successivement dans les orifices 620 et 600 puis dans l'ouverture 210 pour être bloquée dans la cavité 220. L'autre extrémité 50 du câble 5 est introduite successivement dans les orifices 621, 601, 610, 640, 641, 611 et enfin bloquée dans la cavité 221.The
Ainsi le scellé est protégé d'une part par les pattes 60 et 61 et d'autre part par le câble 5 qui plaque le bloc 200 contre le container, le câble 5 étant de longueur adéquate.Thus the seal is protected on the one hand by the
Dans ce mode de réalisation il n'est pas nécessaire que le câble 5 comporte deux extrémités 50 et 51 encliquetables dans le bloc femelle 200, l'une des deux pouvant être sertie d'origine dans ledit bloc femelle.In this embodiment, it is not necessary for the
Il va de soi que la présente invention ne saurait être limitée à la description qui précède et qui est susceptible de subir un certain nombre de modifications sans pour autant sortir du cadre de l'invention resultant des revendications suivantes.It goes without saying that the present invention cannot be limited to the preceding description and which is liable to undergo a certain number of modifications without departing from the scope of the invention resulting from the following claims.
