Description

The present invention relates to a secure container for the transport and / or storage of values, comprising a product of staining and / or destruction of values.

More particularly, the invention relates to an improvement in the distribution of a product of staining and / or destruction of values in such a container.

Containers for transporting and / or storing secure valuables may contain a chemical intended to render the values unusable in the event of an attempted break-in.

The product of staining and / or destruction of values is usually contained in a reservoir, for example a glass or polymer bulb.

Moreover, the values are generally contained in a bag, for example polymer, to protect them and facilitate their transport.

When triggering, pyrotechnic means provided then have a dual function. The detonating effect of the pyrotechnic means makes it possible to break the reservoir containing the product of staining and / or destruction, thus ensuring the release of the product and its propulsion towards the values, and at the same time destroying the bag containing the values in order to expose them to the product.

• une perte du produit lorsqu'il est distribué sur les valeurs inaccessibles car encore protégées par le sac ;
• une perte du produit par distribution du produit de maculation et/ou de destruction en dehors de l'espace où se trouvent les valeurs ;
• une dégradation au niveau moléculaire du produit de par la violence et l'immédiateté de l'onde de choc de la détonation ; et
• une vaporisation violente du produit ce qui induit une évaporation au contact des parois du conteneur contenant les valeurs.

However, it has been found that this process does not always provide the desired satisfaction. Indeed, the concomitance of the action and the violence of the detonation which takes place over a period of a period of the order of a microsecond can result in one or more of the following disadvantages:

• a loss of the product when it is distributed on inaccessible values because still protected by the bag;
• a loss of the product by distribution of the staining and / or destruction product outside the space where the values are;
• a degradation at the molecular level of the product due to the violence and immediacy of the shock wave of the detonation; and
• a violent vaporization of the product which induces evaporation in contact with the walls of the container containing the values.

The object of the present invention is therefore to propose a container for transport and / or storage of values improving the distribution of the product over the values and avoiding the loss of efficiency, in particular by making it possible to confer on the product a speed and a direction of controlled displacement.

Consequently, the subject of the invention is a container for transporting and / or storing values comprising values possibly contained in a bag, at least one reservoir of product for staining and / or destruction of values, pyrotechnic means capable of be triggered by control means, comprising a device delaying the distribution of the chemical on the values.

This device makes it possible to confer on the product staining and / or destructive values a controlled movement speed and a controlled direction in order to increase the efficiency.

The proposed improvement is therefore specifically focused on controlling the speed and distribution of the staining and / or destruction product.

The invention will be better understood on reading the description which follows, given solely by way of example and with reference to the appended figures, which show:

By its design, the device delaying the distribution of the staining product and / or destruction on the values, produces an effect delaying between the moment of destruction of the bag containing the values and the distribution of the product of staining and / or destruction on the said values. This time difference between the cutting of the bag containing the values and the distribution of the product corresponds to the time of movement of the product of staining and / or destruction in the device.

For this purpose, the device is designed to absorb the kinetic energy of the detonation and thus to avoid that the product reservoir is perforated by said detonation.

According to a preferred embodiment, the device 1 takes the form of a flexible and removable plate 12.

Damping by the presence of the flexible polymer reservoir containing the staining product in the conduit of the device also contributes to the delaying effect of the distribution. Advantageously, the reservoir is partially filled with staining and / or destruction product. Indeed, the gas bubble thus formed creates additional damping. Furthermore, this embodiment allows a mixture of the product in the tank depending on the movements of the container.

Advantageously, the conical shape of the device 1 delaying the distribution of the product on the values constrains and channels the flow of the propulsion gas from the detonation to the reservoir containing the product of staining and / or destruction allowing the focusing of the blast effect on the reservoir of staining and / or destruction product. The shape makes it possible to avoid a loss of propulsion flow in the edges of the device.

The conical shape of the device 1 near the chemical reservoir facilitates the flow of the staining and / or destruction product at the outlet of the distribution enclosure.

On the other hand, the reservoir of maculation and / or destruction product is disposed inside the conduit of the device and thus partially obstructs the latter upstream of the cutting gate, which leads to a partial shape of seal when the tank is emptied of the product, as shown on the In fact, it is essentially only the product of staining and / or destruction that passes through the cutting gate after opening the reservoir which is torn by the plurality of pins and knives integrated in the grid and not the residual gases of the blast effect of the detonation. This principle avoids the vaporization effect by gas interference.

The temperature in contact with the explosive, in this case a detonating cord, is of the order of 3000 ° C. In operation, this exotherm is absorbed by the product of staining and / or destruction, and can lead to degradation of the part of said product in contact with the hot gases and which would be heated beyond its losing point of decomposition due to its desired properties.

There is a marked improvement in the effectiveness of the staining and / or destruction product which is uniformly and judiciously distributed over the values after the bag surrounding the values has already been destroyed.

FIGS are diagrammatically illustrated in the figures, a container for transporting and / or storing values according to one embodiment of the invention.

The container can be portable or not and can be in various forms and be used in all cases where it is desired to secure values during the transport of values or when storing such as a pedestrian transport container, a suitcase , a safe, a cash machine, a recycling machine or others.

The values 9 are not shown in FIGS. 2 and 3 for the sake of clarity, and are illustrated in the form of a bundle of bills in FIG. 1 B. In general, the values can be, for example, paper documents, banknotes made of cellulose or plastic polymer, bank cards or identification cards made of plastic or any other valuable support.

Generally, the values are surrounded by a bag 10, which is generally made of polymeric material, in particular polyethylene, which can be torn.

The device 1 comprises at least one, and preferably two tanks 2 containing one or more staining products and / or destruction.

Preferably, the reservoir 2 of staining and / or destruction product is in the form of a welded bag. Preferably, the reservoir is made of a flexible material, for example polymer. Among the polymers, polyethylene, polypropylene, FEP or PFA are particularly preferred. The choice of the material depends inter alia on its resistance to the products of staining and / or destruction. Moreover, it is desirable that it is susceptible to being torn.

The product of staining and / or destruction contained in the tank 2 is intended to render the values unusable. Preferably, it acts by alteration or destruction of values.

It is understood that the products include precursors producing the effect of staining and / or destruction after reaction between them or with air, for example.

The alteration can be carried out for example by staining. In this case, a suitable product can be chosen from inks and pigments.

Preferably, the values are rendered unusable by destruction. The adapted product is then chosen according to the support of the values. These may be products with a high heat in contact with air or water, leading to combustion, or melting in the case of polymer-supported values.

For paper values, it can also be strong mineral acids, such as in particular sulfoperiodic acid or chlorosulfonic acid or products giving off acidic vapors on contact with, for example, air or water. Preferably, the product is in liquid solution form.

The container 8 further comprises pyrotechnic means 4, which are connected to control means 11.

The pyrotechnic means 4 comprise means forming a traditional pyrotechnic initiator and means generating a detonation, itself generating a breath effect.

When they are fired by the control and control device 11, the pyrotechnic means 4 have the function, on the one hand, of instantaneously causing the rupture of the bag 10 containing the values by the blast effect caused by the detonation 5, and on the other hand said detonation causes a blast effect 6 allowing the propulsion of the chemical and its dispersion on the values 9.

The control means 11 can trigger the pyrotechnic means 4 in case of detection of a predetermined event. For this purpose, they are capable of generating sufficient energy to trigger the initiation of pyrotechnic means. Different types of control means are known in the state of the art. In particular, the means described in patent applications FR 2 821 382 and FR 2 844 294 are suitable. They are connected to the pyrotechnic means by connection wires.

The container and the device illustrated in Figure 1 B, 2 and 3 further contains a cutting grid 3 between the values 9 and the product tank 2.

The cutting grid 3 of the product reservoir is preferably provided on its side facing the reservoir with a plurality of projecting openings, preferably forming pins and knives. It is preferably made of a rigid material, for example polymer, metal or ceramic. The protruding pins and knives create openings through laceration in the tank 2 when it is crushed against the cutting grid 3 by the gas expansion 6 of the pyrotechnic means 4.

The openings made allow the passage of the product at a speed which is delayed with respect to the initial detonation of the pyrotechnic means.

The number, the arrangement and the size of the openings of the grid 3 are judiciously arranged in order to generate the appropriate lacerations and thus to control the speed of propulsion of the chemical product and its dispersion in order to ensure a correct distribution on the values 9. They can be determined on a case-by-case basis, in particular according to the density and the viscosity of the product of staining and / or destruction.

The pyrotechnic means are preferably detonating cord cutters, known in themselves. They usually include a pyrotechnic initiator and a detonating cord. In the case of the use of two dispensing devices, the arrangement will be realized as shown in Figure 1 B, that is to say that the detonating cord chopper will be mounted forming an unfinished loop so that it is initiated using a single initiator.

In the event of a predetermined event, such as an attempt to break the container, the control means 11 send a signal likely to trigger the pyrotechnic means 4.

It is therefore conceivable that the particular means of the device, including the arrangement in the container of the pyrotechnic means 4, the reservoir or tanks 2 of the staining and / or destruction product, the arrangement and the shape of the cutting grid 3 and the arrangement and the shape of the device 1 delaying the distribution of the product on the values 9 have a certain advantage in terms of the dispersion of this product on these values.

Of course, other embodiments of the container described can be envisaged.
