Definitions

  • the present invention relates to a method of destroying objects or products stored in an alarm-protected safety enclosure, there being used a destructive agent which when an alarm is triggered is distributed over the product or products and therewith mark and/or destroy the same.
  • the invention also relates to a device for carrying out the method.
  • Safety containers for the transportation of valuable objects normally include a destructive agent in the form of ink cartridges or ink ampules which are activated in the event of unauthorized manipulation of the container, so as to deface or destroy the contents of the container.
  • WO 92/07159 teaches a destructive device in which ink-defacement of valuable products contained in a safety enclosure is improved with the aid of an explosive device.
  • the destructive efficiency of this arrangement has been found wanting in practice, since certain parts of the products sometimes remain undamaged and can be used by the thief, contrary to intentions.
  • the object of the present invention is to provide a method and a device which, when necessary, will destroy effectively products that are contained in a safety enclosure. This object is achieved with a method and a device having the characteristic features set forth in the following Claims.
  • a primary shockwave which will split or flake-up the wrapping and/or the bundled banknotes or other products, so as to expose for coaction with the destructive agent a much larger surface area than that exposed with earlier known devices in this respect.
  • the destructive efficiency of the invention is further enhanced by coaction between a first and a second explosive substance.
  • the inventive device takes-up only a small amount of space and is of simple design and construction, and can be used together with varying explosive compositions and provides many alternatives with regard to the positioning of the explosive or explosives.
  • the device will operate with both single-component and multicomponent destructive agents of different types, and also different agents for destroying magnetic tapes, diskettes and other information carriers.
  • the inventive device can be readily produced in desired lengths and can be adapted to desired requirement specifications.
  • the inventive device affords both technical and economical advantages.
  • FIG. 1 is a schematic cross-sectional view of a first embodiment of an inventive destructive device
  • Figs. 2-4 are schematic cross-sectional views of alternative embodiments of the inventive destructive device
  • Fig. 5 is a schematic view of the destructive device from above.
  • the destructive device 1 illustrated in Fig. 1 includes a casing in the form of, for instance, from an aluminium extruded profile 10.
  • the housing/profile 10 includes a cavity 11 which extends along the full length of the profile and accommodates a destructive agent 50.
  • the front side 12 of the profile 10 includes a groove or recess 13 which accommodates a first explosive string 61.
  • the front side 12 of the profile or housing is intended to face towards the product or products 100 to be destroyed upon unauthorized manipulation of the container.
  • the groove or recess 13 preferably extends along the whole of the profile 10.
  • the destructive device 1 of the Fig. 1 embodiment also includes a groove 14 or a recess 14 for accommodating a second explosive string 62.
  • the recess 14 extends along the whole of the profile 10 and is located in a region of the cavity 11 that faces towards the rear side 15 of the profile 10.
  • the profile 10 has provided at its corners so-called screw pockets/screw grooves 16 which enable two end plates 20 to be readily screwed to the profile 10, so as to cover both ends thereof.
  • the destructive device 1 illustrated in Figs. 1 and 5 also includes a destructive agent 50, which may be any one of many different kinds.
  • the destructive agent 50 may be a single-component heavily staining liquid or ink encapsulated, for instance, in a thin-wall plastic hose 51 which is sealed at both ends thereof, the length of the closed plastic hose 51 coinciding essentially with the length of the profile 10, so that the cavity 11 will be adequately filled.
  • the destructive agent 50 may alternatively comprise a two-component liquid, for instance two-component polyurethane, wherein the different liquid components for instance are each encapsulated in a respective thin-wall plastic-foil hose 52, 53 which is sealed at both ends thereof.
  • the closed plastic hoses 52, 53 share the cavity 11 and together extend essentially along the full length of the cavity 11, as exemplified in Fig. 3.
  • the destructive agent may be comprised of many different types of chemicals or substances, and that the destructive agent may be in powder form as an alternative to a liquid form.
  • the plastic-foil hoses may sometimes be omitted, provided that the cavity 11 is effectively sealed in some efficient manner.
  • the first explosive substance 61 of the Fig. 1 embodiment may have the form of a cordtex or pentyl string, which may optionally be encased in plastic and which extends along the full length of the groove 13.
  • the second explosive substance 62 may also have the form of a cordtex string or a pentyl string and optionally encased in plastic and extend along the full length of the groove 14.
  • the explosive substances 61 and 62 are connected in an electrical alarm circuit incorporated in the safety enclosure or container and are preferably connected so that the first explosive substance 61 will be triggered shortly before the second explosive substance 62, for instance with a time lapse of 1 ⁇ s.
  • the first explosive substance 61 and, when applicable, also the second explosive substance 62 will conveniently include means, for instance an electrically conductive wire, which will detect, e.g. through measurement of resistance, any function disturbing breakage of the explosive strings.
  • Figs. 2-4 illustrate by way of example different alternatives in the positioning of the explosive strings.
  • the destructive device illustrated in Fig. 2 uses only the aforesaid first explosive string 61.
  • the destructive device illustrated in Fig. 3 uses two first explosive strings 61, which in this case have been placed in grooves 17 on respective sides of the opening/groove 13, and two second explosive strings 62 placed in respective grooves 18 in the rear wall of the cavity 11.
  • the destructive device includes three first explosive strings 61, of which one is placed in the outlet groove 13, and one second explosive string 62 which is placed in the rear wall of the cavity 11.
  • the destructive device 1 is placed in an alarm-protected safety container, with the first explosive substance 61 and, when applicable, the second explosive substance 62 connected to the alarm arrangement of the safety container.
  • the length of the destructive device 1 will preferably be the maximum permitted by the container, and the destructive device is placed as close as possible to the products or objects 100 to be destroyed upon unauthorized manipulation of the container, wherewith the front side 12 of the destructive device is directed towards the products 100, which may, for instance, have the form of plastic-wrapped, sealed bundles of banknotes.
  • the first explosive substance 61 acts at least partially on the product/products 100 before the product/products is/are acted upon by the destructive agent 50 accommodated in the destructive device. It will be understood that the first explosive substance 61 propagates freely in a direction towards the product/products 100. It will also be understood that the device will always include at least one explosive charge which acts at least partially outwards against the product/products 100 and therewith open the wrapping material and shred or flake-up the valuable products while increasing the surface area available to the destructive agent. The inventive procedure ensures that the valuable products are acted upon by the explosive forces before the destructive agent has time to reach the products.
  • the groove 13 functions as an outlet zone for the destructive agent 50.
  • the first explosive substance 61 will act outwardly against the products 100 and also inwardly against the destructive agent 50.
  • the second explosive substance 62 acts against the destructive agent 50 so as to puncture or rupture the capsule of the desctruction agent and propels the agent through the outlet zone 13 and onto the already damaged products 100.
  • Coaction between the first explosive substance 61 and the second explosive substance 62 is most effective when the first explosive substance is exploded shortly before the second explosive substance, for instance with an intermediate time span of 1 ⁇ s. It will be understood, however, that the first and the second explosive substances 61 and 62 may be exploded simultaneously.
  • the first explosive substance 61 is effected in disintegrating or splitting-up the valuable products 100 as well as in propelling the destructive agent 50.
  • the first explosive substances 61 are effected in disintegrating or splitting-up the valuable products 100 and the second explosive substances are effective in propelling the desctuctive agent 50.
  • the first explosive substances 61 are effective in disintegrating or splitting-up the valuable products, while the destructive agent is distributed by virtue of coaction between the first explosive substance 61 placed in the outlet zone 13 and the second explosive substance 62.
  • the destructive agent When the destructive agent is comprised of more than one component, these components will be mixed effectively by the explosive substances prior to leaving the destructive device through the outlet slot 13.
  • first and the second explosive substances can be triggered simultaneously when their mutual positions are such that the first explosive substance will act on the products 100 before the second explosive substance acts thereon. Otherwise, the earlier mentioned time lapse between detonations is highly important.
  • the second explosive substance 62 may also be placed directly in the space or cavity 11, if so desired.
  • the second explosive charge may have the form of an explosive powder coated on the inner wall surface of the cavity 11.
  • the second explosive charge may have the form of a string of pentyl explosive placed directly in the cavity 11.
