Description

I The present invention relates to the field of transport and / or

transport of

  paper securities such as, in particular, banknotes and documents.

  During the so-called security transport of valuables, banknotes or documents, these are usually placed in a transportable container by hand in order to

  allow transportation between the vehicle and the collection or drop-off location.

  Transport is provided in particular by means of armored vehicles driven by 10 armed men.

  There are also so-called "alternative" systems, in which unarmoured vehicles are used accompanied by unarmed men. In the "alternative systems", a security device is used which makes it possible to neutralize the values in the event of an attempt to break into the container by

smearing of these values.

  The Applicant has also developed a safety device in which in the event of an attempted break-in, the values are brought into contact with a destruction product acting by chemical combustion. These destruction products then act as oxidizers for a redox reaction, the paper values

playing the role of fuel.

  Destruction of paper can be accomplished by chemicals. This rapid destruction of the paper can for example be obtained by using strong mineral acids, and preferably strong oxidizing acids. Such acids are for example sulfuric acid, nitric acid, perchloric acid, perbromic acid or periodic acid. In addition, combinations of these products

can be considered.

  Such a destruction product is for example a mixture of sulfuric acid and periodic acid, in particular a mixture of 15 to 25% by volume of acid

  sulfuric (for example) and 75 to 85% by volume of periodic acid.

  By destruction of values is meant damage such as the values

are rendered unusable.

  In addition, the regulations currently in force in France require that 20% 5 of each side of each ticket is irretrievably destroyed and neutralized, and this immediately. Furthermore, the weight and the size of the transport container are limited in terms of ergonomics, we seek to reduce the size and weight of the safety device and therefore of the on-board destruction product. Thus, it is desired that the destruction of 20% of each side of each ticket can be carried out by a device having a weight ratio of 25% of destruction product for

% of paper values.

  The invention aims to overcome the drawbacks of existing security devices by proposing a security device for transporting or storing paper values which, while having a reduced volume and weight, allows destruction of paper values in accordance with the regulations in attempted break-in. In order to achieve or even reduce this ratio between the oxidizer and the fuel, it is proposed according to the invention that part of the container and / or of the envelope containing the values be made of a material capable of combining with the product of destruction and to contribute to the destruction of the values in the event of an attempted break-in. Such a device then makes it possible to take on a reduced quantity of destruction product and therefore has a reduced weight, while ensuring an identical destruction result. At the same time, it can reinforce the envelope or container, which increases the resistance

mechanical of the device.

  The invention therefore relates to a security device for the transport or storage of paper securities, comprising a container containing said values, a sensor capable of detecting an attempt to break into the container, a reservoir containing a product for destroying securities. , a pyrotechnic trigger capable of releasing the destruction product from the tank over all of the values, and an auxiliary material for destroying the values

  forming an integral part of the container and / or the sensor.

  According to other characteristics of the invention: - the sensor is a flexible printed circuit attached to the interior surfaces of the container or else a conductive wire inserted in the auxiliary destruction material; the auxiliary material for destroying securities is chemically inert before being brought into contact with the main destruction product; - that the destruction product is one or more mineral acids; the auxiliary destruction material is chosen, for example, from the group consisting of ammonium nitrate, lithium nitrate, magnesium nitrate, magnesium perchlorate, potassium iodate, potassium metaperiodate, potassium nitrate, sodium iodate, sodium metaperiodate, their hydrates, alone or as a mixture; - the destruction product and the auxiliary material includes a pigment or dye allowing the traceability of the container and the values transported in the event of triggering; - the auxiliary material for destroying values is associated with a binder; - the material associated with a binder is present in extruded form; - the device also comprises a microprogrammed system associated with a Radio Frequency device for receiving control signals

  likely to control the pyrotechnic release.

  In addition, the auxiliary destruction material is preferably inaccessible except

in the event of an attempted break-in.

  It is moreover preferable that it is not or not very toxic to humans and does not present any danger for the environment.

  The device according to the invention can be used in alternative systems using the smearing technique. In this case, the auxiliary material for destroying values can comprise coloring products such as pigments. According to a preferred embodiment, the security device comprises a destruction product allowing the chemical combustion of the paper values by

  redox, for example a strong mineral acid.

  Such a device for destroying values by chemical combustion is described in French patent application No. 01 08 826 filed on July 3, 2001 by the first applicant.

  The auxiliary destruction material is then advantageously chosen from oxidizing compounds. Among these compounds are particularly preferred the salts of oxidizing acids such as nitrates, iodates, chlorates and perchlorates. Where appropriate, these salts can be used in hydrated form.

  In particular, the auxiliary material for destroying values is chosen from the group consisting of ammonium nitrate, lithium nitrate, magnesium nitrate, magnesium perchlorate, potassium iodate, potassium metaperiodate, potassium nitrate, sodium iodate,

  sodium metaperiodate and their hydrates or mixtures thereof.

  It is preferable that the auxiliary destruction material is solid. It's not

  however not a necessary condition when combined with a binder.

  The auxiliary material for destroying values can be integrated into the container and / or the sensor by various means. Thus, the material can be applied, for example by coating, spraying or any other means of a solution or composition containing it directly on the surface of the envelope or of the container. It is also possible to produce a woven or nonwoven from the auxiliary material of destruction of values coextruded with a polymer

  suitable, such as polybutadiene for example.

  The invention will be better understood on reading the description which follows, and

  made with reference to the accompanying drawing given by way of example, in which: FIG. unique: shows a view in elevation and in section of a safety device according to an embodiment of the invention. The security device comprises a container (1) generally made of resistant and light material, for example aluminum or reinforced plastic. The security device also comprises a sensor (8) capable of detecting an attempted break-in. Preferably, the sensor (8) is fixed on the

internal faces of the container (1).

  It may for example be an envelope formed from a flexible printed circuit or

  a conductive wire whose conductivity is modified during its destruction in the event of an attempted break-in or in the event of significant deformation. The conductivity of the circuit then goes from a closed circuit level to an open circuit. Such an envelope is described, for example, in the application filed on behalf of the applicant FR 2 822 032.

  Securities or banknotes or bags containing said securities or notes

  bank (4) are arranged in the container (1).

  The trigger system is preferably configurable and generally controlled by radio frequency. Such a control and command device is for example described in French patent application No. 01 02 750 filed on

  February 28, 2001 by the plaintiff.

  A radio frequency identification device (5) is preferably associated

  container (1) to allow the definition of a security perimeter. A microprogrammed system (6) is connected to this radio frequency identification device (5). The micro-programmed system is capable of managing the command to destroy the values via a pyrotechnic trigger (3). The transceiver

  radio frequency signal receiver (5) allows the pyrotechnic trigger (3) to be controlled remotely and / or in the event of a micro-programmed system (6)

  away from the device beyond the security perimeter.

  The security device also comprises at least one tank (2) of destruction product. The reservoir (2) is made of a material inert towards the destruction product, for example a glass or a polymeric material such

than polyethylene (PE).

  On command of the micro-programmed system, the pyrotechnic trigger (3) explodes and generates a breath. The breath thus generated has mainly two functions. On the one hand, it makes it possible to break the reservoir (2) which pours its contents

  by gravity and / or by projection in the container, in contact with paper values.

  i5 On the other hand, in the case of banknotes in particular, the breath generated by the pyrotechnic trigger (3) makes it possible to separate the bundles of bills from one another, and the bills themselves in the bundles of bills and thus facilitates the l access of the destruction product to all the banknotes. This effect is particularly effective for separating bundles of new banknotes. Preferably, the pyrotechnic trigger (3) consists of several initiators coupled in parallel. The contact between the destruction product and the values then leads to the

  chemical combustion of paper securities, causing their destruction.

  According to the invention, the container (1) and / or the envelope (8) is at least partially

  made of auxiliary material for destroying values.

  In order to facilitate industrialization and shaping, the auxiliary destruction material is preferably mixed with one or more binders ensuring

  stiffness such as polybutadiene, then extruded.

  In this way, the auxiliary product forms an integral part of the device (1) and / or of the casing (8), and can also perform functions of reinforcing

  structure or mechanical insulation. In the event of an attempted break-in, it contributes, by its oxidizing action, to the destruction reaction caused by the destruction product of the cellulose making up the paper values.
