Definitions

• the present invention relates to a device for compressing a reservoir containing a product or smearing liquid, usable especially in the secure transport of funds or valuables, for the projection of said product or liquid on said funds or objects, in case of aggression, said smearing device preferably being used in a cassette-type secure enclosure for automatic ticket dispensing, or container type for conveying said documents or valuables from a shipping point to a destination point.
• the smearing devices generally consist of a power source, an electronic card which manages the putting into service of said device and activates the triggering of a device for compressing a tank during the detection of a break-in. or attempted break-in, the detection being carried out by means of sensors of the thermal, hydrometric, gyroscopic, infrared, positional contact type, etc., capable of detecting any malfunction.
• the compression device compresses a reservoir containing a product or dye or aggressive liquid, thus allowing the perforation of said reservoir which releases the product or liquid, said product or compressed liquid being then projected, by means of sprinkling, on documents or valuables that are so degraded.
• Compression devices known to those skilled in the art are variable, but generally use a similar technique of triggering a pyrotechnic charge which releases, with a high intensity, a breath or a gas capable of either compressing the reservoir directly or moving a plate, such as a piston, which compresses said reservoir or directly expels the smearing liquid.
• Compression devices and / or devices smearing are generally not hermetic, because of their design, resulting in a loss of gas emitted during the explosion of the pyrotechnic charge, tending to reduce the intensity of the load, and thus to reduce the compressive force on the tank.
• the compression devices consisting of a piston, implemented generally by means of a plate which slides inside the body of the smearing device to compress the reservoir, as for example in the patent application FR 2.858.005
• the explosion of the charge exerts a strong pressure on the plateau, but with a very irregular distribution; the plate is therefore very likely to tilt inside the body of the device, tending to bend the two parts, which reduces the compressive force on the tank and limits the complete recovery of the plate which, moreover , is inclined.
• the tank can not be emptied in its entirety.
• the spraying means on the smearing device are designed to distribute the deflagrator liquid in various places in the secure enclosure in order to spray all the documents or valuables. It is therefore generally provided several points of perforation on the reservoir for injecting the liquid in all the channels provided on the spraying means. Due to the poor distribution of the compressive force on the reservoir, the perforation of said reservoir is not synchronized and the ejection of the liquid out of the reservoir varies according to the offset between each of the perforations and according to the random compression of the reservoir; the smudging is not homogeneous and some documents or objects of value can still be recovered during a break-in.
• smearing devices are also known for example the patent application FR 2,836,461 which describes a cylindrical device having a circular central chamber closed at its ends by two lids, said chamber containing smearing liquid.
• the two lids comprise a circular and peripheral weakening line.
• the two lids each comprise an axial cylindrical portion, one being solid and the other hollow, the two cylindrical portions being slidably mounted relative to each other such as a piston.
• These sliding mounted parts receive a pyrotechnic generator.
• the triggering of the pyrotechnic generator makes it possible to emit a gas inside the sliding mounted parts, the pressure exerted by this gas makes it possible to detach the two lids closing the chamber at their line of weakening.
• US Patent 2004/0007165 discloses an ink device for protection against theft.
• This device comprises a movable element consisting of at least one compression plate, a tank and motor elements that can be activated by a mechanical triggering device.
• the motor element allows the displacement of the plateau of compression, from an initial position where the closed tank is full to a final position where the tank is perforated and emptied of its contents.
• the motor element consists of springs that exert pressure under the compression plate. The expansion of the springs moves the tray which compresses the reservoir to perforate it and empty it of its smearing ink.
• this trigger device described in US 2004/0007165 is purely mechanical.
• This mechanical triggering device is subjected to a retaining force of the compression plate, this retaining force being proportional to the pressure exerted by the springs under the plate, said springs serving to move the plate when the mechanism is triggered.
• the trigger is obtained by a translation of the mechanism during an attempted forced opening of the smearing device, which releases the compression plate. The restraint force therefore tends to oppose the translation of the mechanism. The mechanism may eventually become blocked and prevent the device from functioning properly.
• the present invention proposes a new mode of design of a reservoir or bag compression device, adaptable to any type of document smudging device or valuable objects, ensuring a proper distribution of the compressive force exerted by the tray on said tank in order to perforate it simultaneously at the various points provided for this purpose, and to promote uniform spraying on the documents or valuables, thus rendering them all useless.
• Another advantage of the present invention is to allow the complete compression of the reservoir, and therefore the use of the entire product or liquid when smearing documents or valuables.
• Another advantage of the present invention is to guarantee an immediate pressurization of the reservoir in the compression device to ensure a uniform perforation of said reservoir and thus a homogeneous evacuation of the ink contained therein for spraying the assembly. documents or valuables.
• the present invention also aims to ensure immediate triggering of the compression device, - without risk of failure of the trigger device, and instantaneous perforation of the reservoir during an attempt fraudulent opening of the smearing device.
