Description

The present invention relates to a security device for transporting and / or storing printed values with printing inks.

It is known that the transport and / or storage of values of this type are currently carried out using receivers of these values, these speakers being able for example to be formed by chests, armored cabinets, secure suitcases or cassettes. cash dispensers.

Despite all the precautions taken, there has been a recent upsurge of attacks against, for example, the transport vehicles used and the crews of the latter.

It was then decided to associate to the receiving receivers of values, tanks of maculant adapted to disperse on the values therein and whose operation is controlled by control means.

Different types of remote control means or operators of a vehicle, for example, have been developed.

These staining products are in fact formed by inks or pigments theoretically intended to render the values unusable. However, there is no guarantee that washing and chemical treatment products so smeared have not been or will not be discovered, which would then allow for example to criminals, to wash and treat these values for them. put back into circulation.

It is conceivable then that the protection of paper values by staining is not completely reliable and no longer plays its dissuasive role. The object of the invention is to propose a device for solving this problem.

For this purpose, the subject of the invention is a security device for the transport and / or storage of printed values, of the type comprising a receiving chamber of these values, associated with at least one solubilization product reservoir of the printing ink binder and the inks themselves comprising a sulfonating agent, adapted to disperse on the values under the control of control means .

On the other hand, it is known that bank notes and printed values are generally printed with inks composed of inorganic pigments and an organic binder. Some inks, including ultra-violet light reflecting inks, are composed of organic compounds.

A banknote exposed to chlorosulfonic acid and then immersed in a water bath, releases pigment and metal particles. This phenomenon is referred to as the solubilization of inks. It is concluded that chlorosulfonic acid acts at the level of organic compounds, and in particular binders.

It is assumed that chlorosulfonic acid has a sulphonating action on these organic compounds, thus rendering them soluble in water and leading to the disintegration of the dye. This reaction would mainly involve binders, but could also reach other organic compounds present on the surface of the printed values, in particular inks. It is very fast, and complete in a period of time of the order of the second.

Thus, the device described makes it possible to render the printed values unusable in the event of an infringement in a fast and efficient manner.

• les moyens de commande sont adaptés pour déclencher le fonctionnement d'un déclencheur pyrotechnique de dispersion du produit sur les valeurs, associé au réservoir ;
• le produit chimique comprend en outre un composé oxydant et/ou un composé déshydratant et/ou un composé acide tels le peroxyde d'hydrogène, l'acide para-toluenesulfonique ou le chlorure de sulfuryle ;
• il s'agit d'un distributeur automatique de billets (DAB) ou un container de transport de fonds.

According to particular embodiments, the security device comprises one or more of the following characteristics:

• the control means are adapted to trigger the operation of a pyrotechnic product dispersion trigger on the values associated with the reservoir;
• the chemical further comprises an oxidizing compound and / or a desiccant compound and / or an acidic compound such as hydrogen peroxide, para-toluenesulfonic acid or sulfuryl chloride;
• it is a cash machine (DAB) or a fund transport container.

The invention finally relates to the use, in a security device for the transport and / or storage for the destruction of values printed with printing inks, of a solubilization product for inks comprising at least acid chlorosulfonic.

The invention will be better understood on reading the description which follows, with reference to the appended figure which represents a block diagram illustrating the general structure of a device according to the invention and non-limiting examples.

It has in fact shown in this figure a safety device for the transport and / or storage of printed values.

This device comprises an enclosure for receiving these values, this enclosure being designated by the general reference 1 and being for example in the form of a secure case or a banknote dispenser cassette, the values being, for to them, designated by the general reference 2, and presenting for example in the form of banknotes or other, such as securities, checks, contracts, etc..

The printed values 2 preferably contain 2 to 10% and especially 5% of PVA (polyvinyl alcohol).

This chamber is associated with at least one reservoir 3 of ink solubilization product 4 adapted to disperse on the values, under the control of control means designated by the general reference 5.

These control means are connected to means for detecting a triggering event, for example an unauthorized opening contact 6 of the bag or means 7 for checking the integrity of the bag, for In case of attempted break-in, allow the control means 5 to trigger the operation of means 8 for dispersing the solubilization product of the inks on the values.

These dispersion means comprise for example a pyrotechnic trigger associated with the reservoir, in a conventional manner.

Of course, other control means can be envisaged, such as, for example, means for detecting the reception or not of a security signal, as is known.

The enclosure may also be formed by a safe, an armored cabinet, etc., disposed in a vehicle, a building, etc.

In particular, it is a cash machine (ATM). This type of enclosure imposes certain additional requirements on the pedestrian transport containers. In particular, they are less suitable for a destruction product generating a significant exotherm and an emission of toxic gases that it is necessary to filter with a filter adapted to the nature of the gases emitted. Indeed, the pedestrian transport containers are sealed while the storage cassettes of said values in the cash dispensers are not waterproof.

However, the ink solubilization method generates little exotherm and the gases resulting from the sulfonation can be filtered with a simple filter.

According to the invention, for the solubilization of the inks of the printed values contained in the enclosure, the product 4 has a composition such that, when the printed values are put in contact with the product, the sulphonated chlorosulfonic acid the organic binder of the inks of printing or the inks themselves leading to the disappearance of the printing of the printed values, thus rendering them useless and therefore worthless.

The solubilization of the inks with chlorosulfonic acid is thus obtained, due to a sulfonation mechanism.

The solubilization product of the inks, in particular chlorosulphonic acid, is preferably used in pure form. The product may, however, also comprise another agent and be in the form of a mixture.

In particular, the product 4 used may consist of a mixture of at least two constituents. Thus, the mixture may further comprise useful additives such as hydrogen peroxide, sulfuryl chloride or para-toluenesulfonic acid.

By way of example, the mixture allowing the solubilization of the inks can have the following composition: chlorosulfonic acid 50 to 75% by weight hydrogen peroxide (50% by volume) 25 to 50% by weight

In the following examples, the effectiveness of the solubilization product described was evaluated and compared to that of other products. Unless otherwise indicated, acids are used in pure form.

EXAMPLE 1

In a suitable container, 100 mL of chlorosulfonic acid is poured over 1000 mL of printed values (vignettes) at room temperature and at atmospheric pressure.

After a waiting time indicated in Table 1, the condition of the stickers and the yield are evaluated. The results are summarized in Table 1 below.

Furthermore, the amount of acid is determined which makes it possible to obtain a 25% yield at ambient temperature and atmospheric pressure. The results are shown in Table 2.

EXAMPLES 2 to 4 (comparison examples)

For comparison, sulfuric acid solutions (Example 2), perchloric acid (Example 3) and containing a sulfuric acid and periodic acid mixture were prepared in a weight ratio of 85:15 (Example 4).

The effectiveness of the prepared solutions is evaluated as in Example 1. The results are collated in Tables 1 and 2 below. <b><u> Table 1 </ u></b> Example Solubilization product Action time observations yield 1 Chlorosulfonic acid 1s No additional treatment 100% 2 Sulfuric acid alone 3 min Need for additional mechanical treatment 100% 3 Perchloric acid 1 min Need for additional mechanical treatment 70% 4 Sulfuric acid - Periodic acid 5s No additional treatment 30 % Example Reactivity solution / vignette 1 1: 15 2 1: 1 3 1: 1 4 1: 4

The Applicant has found that the use of the solubilization products indicated ensures satisfactory solubilization of inks, commonly used in banknotes.

The time required to ensure satisfactory solubilization of the inks is advantageously less than a few seconds. We understand that in a safety device such as that described here, when the mixture suitable for the solubilization of inks is spread over the printed values, the inks are solubilized and the printed values become unreadable, unusable, and therefore worthless.
