Tamper revealing inserts (16) are positioned in the strip and formed of coloured varnish which adheres to only one of the surfaces.

Description

L'invention concerne les sachets pour les transferts de fonds et de valeurs financières comportant un dispositif de détection de la première ouverture.The invention relates to bags for the transfer of funds and values financial systems comprising a device for detecting the first opening.

Actuellement ces sachets sont réalisés dans une nappe en matière synthétique et comportent à une extrémité une ouverture, par exemple transversale, dont l'obturation est assurée, comme montré aux figures 1 à 3 annexées, par un ruban adhésif 2 comportant une partie longitudinale 2a collée sur la paroi 1a et le long du bord de l'ouverture 3 du sachet et une partie longitudinale 2b formant un volet rabattable sur l'autre bord de l'ouverture, cet autre bord étant constitué, dans la forme d'exécution représentée, par l'autre partie 1 b de la paroi du sachet 1.Currently these sachets are made in a sheet of material synthetic and have an opening at one end, for example transverse, the obturation of which is ensured, as shown in Figures 1 to 3 appended, by an adhesive tape 2 comprising a longitudinal part 2a glued on the wall 1a and along the edge of the opening 3 of the bag and a part 2b longitudinal forming a foldable flap on the other edge of the opening, this other edge being constituted, in the embodiment shown, by the other part 1 b of the wall of the bag 1.

Pour détecter la première ouverture, c'est-à-dire pour éviter que, lors du transfert du sachet rempli, il soit possible de l'ouvrir, de prélever tout ou partie des valeurs qu'il contient et de le refermer, il est connu d'interposer, entre la couche d'adhésif 4 et le ruban 2 en matière synthétique, un complexe révélateur R1 composé d'un vernis incolore imprimé en formant un marquage 5a à 5d, tel que, par exemple, l'expression « ouvert », et d'une couche d'encre de couleur 6 répartie en aplat, l'un des composants encre-vernis étant choisi parmi ceux n'adhérant pas à l'autre mais adhérant à la matière du volet.To detect the first opening, i.e. to prevent the transfer of the filled sachet, it is possible to open it, to take all or part of the values it contains and of closing it, it is known to interpose, between the layer of adhesive 4 and the tape 2 of synthetic material, a revealing complex R1 composed of a colorless varnish printed by forming a marking 5a to 5d, such that for example the expression "open", and a layer of color ink 6 distributed in solid color, one of the ink-varnish components being chosen from those not adhering to the other but adhering to the material of the shutter.

Ainsi lors de la première ouverture d'un sachet par tirage sur le volet, et comme montré à la figure 4 annexée, la couche d'encre 6 adhérant à l'adhésif 4 et au volet 2b se répartit entre ces deux supports, sauf dans les zones comportant les marques de vernis, par exemple, celles 5c, 5d, puisque n'adhérant pas au vernis. Cette encre reste en totalité sur l'adhésif 4, comme montré en 6c, 6d. Les marques de vernis invisible 5c, 5d sont ainsi dégagées de toute impression colorée et font apparaítre, par opposition dans l'environnement coloré par l'encre adhérant au volet 2b, un texte signalant l'ouverture.Thus when the sachet is first opened by pulling on the flap, and as shown in Figure 4 attached, the ink layer 6 adhering to the adhesive 4 and in shutter 2b is distributed between these two supports, except in the zones with varnish marks, for example, those 5c, 5d, since not adhering to the varnish. This ink remains entirely on the adhesive 4, as shown in 6c, 6d. The invisible varnish marks 5c, 5d are thus freed from any colorful print and make it appear as opposed to the environment colored by the ink adhering to shutter 2b, a text indicating the opening.

Si le volet 2b est à nouveau rabattu et recollé sur la paroi 1 b, au moins une partie des marques 5c, 5d ne coincident pas avec les restes d'encre 6c, 6d correspondants et révèle l'action antérieure d'ouverture.If the flap 2b is folded down again and glued to the wall 1b, at least one part of marks 5c, 5d do not coincide with leftover ink 6c, 6d correspondents and reveals the previous opening action.

Un tel dispositif de détection d'une première ouverture a donné satisfaction jusqu'à ce que soit commercialisées des bombes aérosol délivrant un gaz réfrigérant permettant d'atteindre localement une température de- 40 à - 50°C.Such a device for detecting a first opening has given satisfaction until aerosol cans delivering gas are marketed refrigerant allowing to reach locally a temperature of -40 to - 50 ° C.

En effet, si un gaz réfrigérant est répandu sur l'une quelconque des deux parties du ruban adhésif 2, et par exemple sur le volet 2b, l'adhésif 4 de liaison du volet avec la paroi 1b du sachet perd son pouvoir adhésif et permet, dans certaines conditions d'ouverture, de séparer le volet 2a de la paroi 1 b sans que la fonction révélatrice puisse se réaliser. Il en est ainsi parce que, sous l'effet du froid l'adhésif a tendance a mieux adhérer à l'encre 6 et au vernis 5 qu'à la paroi 1b du sachet qui, en raison de sa réalisation en polyéthylène, est moins adhérent. Il en résulte que, non seulement il est possible d'accéder au contenu du sachet en conservant le pouvoir collant de l'adhésif, qui revient dès que le volet est à nouveau à température ambiante, mais aussi d'effectuer cette opération sans que les marques d'ouverture soient réalisées, c'est-à-dire sans que cette ouverture puisse être révélée. Il est bien évident que sous l'action du gaz réfrigérant, il est également possible de décoller la partie 2a du ruban adhésif de la paroi 1a du sachet.Indeed, if a refrigerant gas is spilled on any one of the two parts of the adhesive tape 2, and for example on the flap 2b, the bonding adhesive 4 of the shutter with the wall 1b of the bag loses its adhesive power and allows, in certain opening conditions, to separate the shutter 2a from the wall 1b without the revealing function can be realized. This is so because, under the effect of cold the adhesive tends to adhere better to ink 6 and varnish 5 than to the wall 1b of the sachet which, due to its polyethylene construction, is less adherent. As a result, not only is it possible to access the content of the sachet while retaining the stickiness of the adhesive, which returns as soon as the flap is again at room temperature but also to perform this operation without the opening marks being made, that is to say without that this opening can be revealed. It is obvious that under the action of refrigerant gas, it is also possible to peel off part 2a of the adhesive tape from the wall 1a of the bag.

Pour remédier à cela le document US 5 391 136 utilise une premier moyen de liaison entre le bord interne du volet et le bord de l'ouverture du sachet et un second moyen de liaison entre le bord externe du volet et la face externe de la paroi du sachet près de l'ouverture, ce deuxième moyen recouvrant le premier en assurant une liaison dite inviolable, alors que le premier assure une liaison dite normale. En pratique les deux moyens sont composés d'un ruban fragile et d'un adhésif agressif, disposé, respectivement sur les deux faces et sur une seule face, pour former un ensemble dit inviolable et très destructible. des impressions de couleurs sont envisagées pour accroítre la perception de la violation se caractérisant par des brisures, des déformations ou l'interruption d'un motif. L'expérience fait apparaítre que le prix de fabrication de tels sachets prend en compte pour près de la moitié le recours à des rubans adhésifs spéciaux et qu'il est souhaitable de limiter leur utilisation dans ce type de sachet.To remedy this, document US 5 391 136 uses a first means of connection between the internal edge of the flap and the edge of the opening of the bag and a second connecting means between the outer edge of the flap and the outer face of the wall of the bag near the opening, this second means covering the first in ensuring a so-called inviolable connection, while the first provides a so-called connection normal. In practice the two means are composed of a fragile ribbon and a aggressive adhesive, respectively placed on two sides and on one face, to form a set called inviolable and very destructible. impressions of colors are envisaged to increase the perception of the violation characterized by broken, distorted or interrupted pattern. Experience has shown that the manufacturing price of such sachets takes into account accounts for almost half the use of special adhesive tapes and it is desirable to limit their use in this type of sachet.

L'invention a pour objet de fournir un dispositif de détection de la première ouverture d'un sachet qui soit insensible à l'action des basses températures, mais en améliorant encore la visualisation de la première ouverture, tout en limitant le nombre de rubans adhésifs à un et en faisant appel à des techniques de fabrication couramment mises en oeuvre par le fabricant de films et de sachets.The object of the invention is to provide a device for detecting the first opening of a sachet which is insensitive to the action of low temperatures, but by further improving the visualization of the first opening, while limiting the number of adhesive tapes to one and using techniques commonly used by the manufacturer of films and sachets.

A cet effet, le dispositif selon l'invention comprend, en complément du complexe de révélation porté par le ruban adhésif et sur chacune des parois du sachet venant en contact avec le ruban adhésif, c'est-à-dire de part et d'autre de l'ouverture ménagée dans ce sachet, des couches complémentaires de révélation, ayant sensiblement la même surface que la partie correspondante du volet devant les recouvrir, chacune de ces couches de complexe révélateur étant composée de marques imprimées par un vernis incolore et d'une couche d'encre colorée, répartie en aplat et recouvrant les marques , l'un des composants vernis ou encre étant choisi parmi ceux n'adhérant pas à l'autre composant.To this end, the device according to the invention comprises, in addition to the revelation complex carried by the adhesive tape and on each of the walls of the sachet coming into contact with the adhesive tape, i.e. on either side of the opening in this sachet, additional layers of revelation, having substantially the same surface as the corresponding part of the flap to cover them, each of these layers of developer complex being composed of marks printed by a colorless varnish and a layer of ink colored, distributed in solid color and covering the marks, one of the varnished components or ink being chosen from those which do not adhere to the other component.

Avec ce dispositif, qui complète celui existant ménagé sur le ruban adhésif, lors d'une tentative d'ouverture par effraction au gaz réfrigérant, l'adhésif du ruban conserve, comme par le passé, suffisamment de pouvoir adhérant pour rester au contact de l'encre déposée sur le volet le portant mais aussi, et cela est nouveau, au contact de l'encre déposée sur la paroi en vis à vis.With this device, which complements the existing one provided on the tape adhesive, when trying to break in with refrigerant gas, the adhesive tape retains, as in the past, enough adhesive power to stay in contact with the ink deposited on the flap carrying it but also, and this is again, in contact with the ink deposited on the opposite wall.

Il en résulte que les couches d'encre et d'adhésif se déchirent par cisaillement en se répartissant de manière aléatoire sur chacune des parties volet-paroi. Cela entraíne le dégagement des marques de vernis sur la paroi et le volet et assure la révélation du message indiquant la première ouverture.As a result, the ink and adhesive layers tear apart. shear by being distributed randomly over each part wall shutter. This results in the release of varnish marks on the wall and the shutter and ensures the revelation of the message indicating the first opening.

Il ressort de ce qui précède que, si la détection à la première ouverture met en oeuvre deux couches révélatrices similaires ménagées respectivement sur le ruban adhésif et sur les parois du sachet, l'une de ces couches étant associées à l'adhésif, elle met à profit la meilleure adhérence au froid de l'adhésif avec les couches d'encre pour obtenir l'action révélatrice, jusqu'alors annulée par le froid. En d'autres termes ce dispositif combine des moyens connus, mais obtient, par une fonction nouvelle, la rupture des couches générant la révélation de l'ouvertureIt follows from the above that, if the detection at the first opening implements two similar revealing layers provided respectively on the adhesive tape and on the walls of the bag, one of these layers being associated with the adhesive, it takes advantage of the better adhesion to cold of the adhesive with the ink layers to obtain the revealing action, hitherto canceled by cold. In other words, this device combines known means, but obtains, by a new function, the rupture of the layers generating the revelation from the opening

    La figure 6 montre que le sachet selon l'invention est constitué par une nappe en matière synthétique 10 repliée à chacune des extrémités 10a, 10b du sachet et dont les propres extrémités 11a, 11b se recouvrent pour former l'ouverture 13. Les extrémités 11a, 11b délimitent donc les parties de la nappe destinées à coopérer avec un ruban adhésif 12 comportant une partie 12a se collant sur la partie 11a de la nappe et une partie 12b, en forme de volet, apte à être collée à la partie 11b de la nappe.FIG. 6 shows that the bag according to the invention consists of a ply of synthetic material 10 folded at each of the ends 10a, 10b of the bag and whose own ends 11a, 11b overlap to form the opening 13. The ends 11a, 11b therefore delimit the parts of the ply intended to cooperate with an adhesive tape 12 comprising a part 12a sticky on part 11a of the ply and part 12b, in the form of a flap, suitable for be glued to part 11b of the tablecloth.

    Comme dans l'état de la technique, le ruban adhésif 12 est composé d'un ruban en matière synthétique comprenant, entre lui et une couche d'adhésif 14, un complexe révélateur R1 composé de marques 15a à 15e imprimées par un vernis invisible et d'une couche d'encre 16, colorée et répartie en aplat. L'un des deux composants vernis 15, encre 16, et par exemple l'encre 16, est choisie parmi ceux n'adhérant pas à l'autre composant, à savoir le vernis 15.As in the prior art, the adhesive tape 12 is composed of a plastic tape comprising, between it and a layer of adhesive 14, a revealing complex R1 composed of marks 15a to 15e printed by a invisible varnish and a layer of ink 16, colored and distributed in solid color. One of the two varnished components 15, ink 16, and for example ink 16, is chosen among those which do not adhere to the other component, namely varnish 15.

    Selon l'invention, chacune des zones du sachet coopérant avec le ruban adhésif 12, à savoir l'extrémité 11a et l'extrémité 11b, est recouverte par un complexe révélateur R2 et R3 composé de marques 25a à 25e imprimées par un vernis incolore 25 et d'une couche d'encre 26, colorée et répartie en aplat, l'un des deux composants encre et vernis étant choisi parmi ceux n'adhérant pas à l'autre composant. Le vernis 25 et l'encre 26 peuvent être identiques, respectivement, au vernis 15 et à l'encre 16 utilisés sur le ruban adhésif 12 de l'état de la technique, mais ils peuvent être différents. A titre d'exemple, le ruban 12 est en polyéthylène, le vernis 15, 25 est à base de cires synthétiques et par exemple est celui commercialisé par la société française REXOR sous la référence PC 140 WT, tandis que l'encre est à base nitrocellulosique et par exemple est celle commercialisée par la société française SICPA sous la référence Série 9230, qui n'adhère pas au vernis.According to the invention, each of the zones of the bag cooperating with the ribbon adhesive 12, namely the end 11a and the end 11b, is covered by a revealing complex R2 and R3 composed of marks 25a to 25e printed by a colorless varnish 25 and a layer of ink 26, colored and distributed in a solid color, one of the two components ink and varnish being chosen from those which do not adhere to the other component. The varnish 25 and the ink 26 can be identical, respectively, with the varnish 15 and the ink 16 used on the adhesive tape 12 of the state of the art, but they may be different. For example, the ribbon 12 is made of polyethylene, the varnish 15, 25 is based on synthetic waxes and by example is that marketed by the French company REXOR under the reference PC 140 WT, while the ink is nitrocellulose-based and by example is that marketed by the French company SICPA under the reference Series 9230, which does not adhere to the varnish.

    La mise en place des composants du complexe révélateur ne pose aucun problème puisque lors de sa fabrication chaque sachet reçoit des impressions diverses auxquelles s'ajoutent l'impression de l'encre 15, 25et du vernis 16, 26.The installation of the components of the revealing complex poses no problem since during its manufacture each sachet receives impressions various to which are added the printing of ink 15, 25 and varnish 16, 26.

    Le deuxième moyen de révélation ne modifie en rien les conditions normales d'utilisation du dispositif de fermeture ni d'ailleurs celles de révélation de la première ouverture puisque, lors de celle-ci, et comme montré figure 8, l'effort d'arrachement exercé sur le volet 12b génère sur l'adhésif 14, adhérant aux deux couches d'encre 16 et 26, des contraintes de cisaillement provoquant sa déchirure en formant des fragments 27a, 27b, 27c de couches complexes, se délaminant en suivant le volet 2b ou en restant sur la paroi 11b en vis à vis. Chaque fragment 27a à 27c se sépare de l'un des supports, volet 2b ou paroi 11b, présentant une adhérence plus faible, c'est-à-dire dans une zone comportant une marque imprimée en vernis incolore, en faisant apparaítre cette marque, comme montré pour celles 25c, 15d et 15e.The second means of disclosure does not change the conditions normal use of the closing device or, moreover, those of revelation of the first opening since, during this opening, and as shown in FIG. 8, the tearing force exerted on the flap 12b generates on the adhesive 14, adhering at the two ink layers 16 and 26, shear stresses causing its tearing by forming fragments 27a, 27b, 27c of complex layers, delaminating by following the flap 2b or by remaining on the wall 11b opposite. Each fragment 27a to 27c separates from one of the supports, flap 2b or wall 11b, having weaker adhesion, that is to say in an area comprising a mark printed in colorless varnish, making this appear mark, as shown for those 25c, 15d and 15th.

    Ainsi, non seulement la marque n'est plus occultée par la couche d'encre colorée mais se distingue nettement par contraste ou opposition avec son environnement par le reste de cette couche colorée l'entourant.So not only is the brand no longer obscured by the ink layer colored but clearly stands out by contrast or opposition with its environment by the rest of this colored layer surrounding it.

    Lors d'une ouverture par effraction au gaz réfrigérant, la révélation de cette ouverture s'effectue dans les mêmes conditions, puisque, la couche d'adhésif 14 n'est pas en contact direct avec une paroi en polyéthylène, matière vis à vis de laquelle elle perd son pouvoir adhérent, mais en contact avec deux couches d'encre vis à vis desquelles elle conserve son pouvoir adhérent.During a break-in with refrigerant gas, the revelation of this opening is carried out under the same conditions, since, the adhesive layer 14 is not in direct contact with a polyethylene wall, material opposite which it loses its adhesive power, but in contact with two layers ink towards which it retains its adherent power.

    Il en résulte que, même à l'état surgelé, le dispositif de détection fait apparaítre des marques révélant la première ouverture et qu'ainsi il n'est plus possible d'ouvrir le sachet par effraction au gaz réfrigérant sans que cette ouverture soit signalée.As a result, even in the frozen state, the detection device appear marks revealing the first opening and thus it is no longer it is possible to break the bag into refrigerant gas without this opening is signaled.

    Il est à noter que, d'une part, la couche composée du vernis 25 et de l'encre 26 se distingue de la couche formée par le vernis 15 et par l'encre 16, par le fait qu'elle n'est pas associée à une couche adhésive 14, et que, d'autre part, la combinaison des deux couches met à profit les conditions d'adhérence privilégiée de l'adhésif avec les encres 16 et 26 pour, dans les conditions d'effraction au gaz réfrigérant, utiliser le différentiel d'adhérence avec les deux marques de vernis 15a à 15e et 25a à 25e, pour entraíner la désoccultation de ces marques.It should be noted that, on the one hand, the layer composed of varnish 25 and the ink 26 differs from the layer formed by the varnish 15 and by the ink 16, by the fact that it is not associated with an adhesive layer 14, and that, on the other hand, the combination of the two layers takes advantage of the adhesion conditions preferred adhesive with inks 16 and 26 for, under the conditions use of refrigerant gas, use the adhesion differential with both varnish marks 15a to 15e and 25a to 25e, to cause the concealment of these marks.
