• the container will, of course, be equipped with a reliable alarm system or security system, of which at least certain parts are located within the container.
• the system is constructed so that the destructive element or elements will always be activated before the security system for the destructive element can be rendered safe by unauthorized methods and before the valuables stored in the container can be removed therefrom unlawfully.
• the security system must have a short reaction time, so as to prevent the system being disarmed by means of a so- called high speed weapon, for instance.
• the main object of the present invention is to provide a particularly designed laminate structure which can be used to great advantage in the construction o_ a wall or a casing of a security container or of a security room or' space. This object is achieved with a laminate structure defined in the following Claims and also with the use of such a laminate.
• the invention can be made thin and light in weight, which, of course, imparts weight advantages to the transport container in which the laminate is used, for instance.

• the material used is an electrically conductive material, and may have the form of wires, filaments or strips of metal or an electrically con ⁇ ductive plastic material, hereinafter referred to genetically as threads.
• the "threads" 5 of material used are coated with an insulating layer. For in ⁇ stance, the threads may consist of copper threads coated with an insulating varnish of the type normally used in small electric motors.
• FIG. 3 illustrates very schematically one method of constructing an alarm mat 2 in accordance with the invention.
• the alarm mat 2 shown partially in Figure 3 is a knitted structure. When the structure is knitted with a single thread 5 solely two thread ends are obtained with the mat, such as to obtain a continuous electric circuit.
• the mat 2 may alternatively be con ⁇ structed from double threads 5, 5', which results in two continuous electric circuits.
• the aforesaid electric circuits are connected together so that the mat 2 will obtain a single electric circuit in which current flows in different directions in the mutually parallel threads 5, 5'.

• the alarm layer/alarm mat 2 is thus comprised of a fine-mesh material, and a central inventive feature of the mat is that it is constructed from one or more insulated, electrically conductive threads, and that the thread or threads is/are disposed to form mutually integral meshes, loops or eyes, for instance of the kind obtained when knitting, crocheting or weaving thread material. This also applies to the use of optical fibres.
• the inventive alarm mat is extremely capable of re ⁇ sisting disturbances in the form of electromagnetic force fields, static electricity and the like.
• Prevailing technical requirements on the alarm layer 2 are factors which control the choice of an appropriate method of manufacture.
• One or more electric signals are transmitted through the mat 2 and any attempt to make a hole in the laminate 10 will result in the fracture of a thread, or a number of threads in the mat, causing the electric signal to be interrupted and an alarm to be triggered .
• the second outer layer or sheet 3 is conveniently constructed in the same manner or in a similar manner to the first outer layer or sheet l.
• the laminate 10 is used so that the outer sheet 1 will form the exterior of the container and the second sheet or layer 3 will form the interior of said container, and the finish and construction of respective outer layers or sheets may be varied accordingly.
• the sheets 1-3 are joined together in some appropriate manner, for in ⁇ stance by gluing, injection-moulding or press-moulding techniques.
• a number of different adhesive binders can be used in this regard, for instance polyester resin or other resins may be used, therewith to produce a stable laminate.
• polyester resin or other resins may be used, therewith to produce a stable laminate.
• a security container or a securi ⁇ ty case can be produced from solely two curved lami- nate sections which overlap one another at their meeting point.
• An example of a transport container or case 20 constructed in this way is illustrated in Figure 4.
• the case 20 illustrated in Figure 4 is constructed from two particularly shaped inventive laminate sec ⁇ tions 10a and 10b, said sections being so configured that when the case is closed, the laminate sections will overlap in an overlap zone 21 which presents the smallest possible gap or clearance 22 between the overlapping parts.
• the case 20 is typically provided with a handle 23 glued to the outside of the case, and also with hinge means, locking devices, etc., which are mounted in a manner which excludes the necessity of perforating the laminate sections.
• a number of electrical contact or detectors 24 and 25 are mounted immediately inwards of the overlapping zone 21, the devices 24 being carried by a strip 26 bonded to the laminate section 10a and the devices 25 being carried by a further strip 27 glued to the other laminate section 10b.
• the strips 26 and 27 will preferably extend around the full perimeter of the container 20, and an appropriate number of electric contact devices 24, 25 are therewith mounted around the container perimeter.
• a security cage is formed by mutually connecting the respective alarm mats 2 of the laminate sections 10a and 10b and the electrical contact devic ⁇ es 24 and 25, so as to form one or more electric signal circuits.
• the circuit or circuits is/are broken when a thread 5, 5' in the mat 2 is fractured or cut as a result of attempting to make a hole in the con ⁇ tainer, and it will be understood from this that the mat 2 will extend over the whole of the container surface.
• a mat overlap is also provided in the overlap zone 21.
• the signal circuit will also be broken when attempting to widen the gap 22, by bending apart the overlapping parts of respective laminate sections in an attempt to unlawfully force the container 20.
• the space between the devices 24 and 25 will alter and therewith break the electric circuit.
• an electronic unit mounted inside the container 20 is an electronic unit and one or more ampules or cartridges which contain a destructive agent, for instance dye cartridges.
• the electronic unit is constructed so as to activate the cartridges or ampules immediately the circuit is broken, so as to destroy or render useless the _schreib,-- perennial--
• the container 20 will also contain a current supply source. It is conceiv ⁇ able in this regard to preset a time at which the destructive element is activated or triggered, with the intention of introducing an additional stress factor for those attempting unlawful access to the container.
• the inventive alarm mat 2 consisting of mutually integral meshes, loops or eyes, will function as a particularly effec ⁇ tive guard against external disturbances, for instance in the form of magnetic fields of different kinds and electrostatic fields and the like, in addition to its aforedescribed hole-security function.
• This second function is achieved because the tensions induced or the disturbances generated by such external distur ⁇ sayes are dampened by the laminate so quickly as to enable the reaction time of the electronic unit to be made so short as to render it impossible to disarm the destructive element in time, even when firing, for instance, a high speed weapon towards the activating device of the destructive element.
• a thread wire, filament, band, etc.
• an electric circuit is, in many instances, a suffi ⁇ cient protection against external disturbances in the form, e.g., of powerful magnetic fields and transient voltages.
• the arrangement of two mutually parallel threads which are connected in an electric circuit with in which current flows in opposite direc ⁇ tions affords a still better resistance to external disturbances»
• the inventive alarm mat 2 will thus effectively prevent disturbance of the electronic and data equipment carried within the container construct ⁇ ed from the inventive laminate sections 10.
• Figure 6 illustrates an example of a throughlet for a signal-carrying cable 30 arranged in one laminate section 10.
• an overlap zone 31 is conveniently provided in the mat 2, so as to eliminate the possibility of a hole being made through the laminate section 10 without resulting in an alarm.
• a knitted mat 2 it is possible to provide an overlap zone of sufficient dimensions for the purpose intended, by knitting a so-called button ⁇ hole in the alarm mat.
• the cable throughlet shown in Figure 6 may be used in conjunction with the illus ⁇ trated security case 20, for instance.
• Figure 7 illustrates an example of a security space or room 40 built from inventive laminate sections 10.
• the joint regions of the laminate sec- tions include overlap zones 41 (see Figure 8), so that the mat 2 will be continuous, as described above with reference to the case 20.
• each overlapping joint is suitably provided with bend- indicating contact devices, similar to the embodiment aforedescribed with reference to the case 20. Some overlapping joins may also be adhesively bonded. Overlapping of adjacent laminate sections at the corners of the room structure 40 can be facilitated with the aid of separate, angled laminate strips 10c. The laminate strips 10c or the angled corner strips may, of course, be placed internally of respective laminate sections 10.
• the room structure 40 is provid ⁇ ed with a door 42, or some similar entrance, and means for indicating overlapping and bending of the laminate section devices will also be provided around the door or like entrance.
• the inventive laminate 10 can thus be used in the construction of containers, rooms or other spaces where it is desired to prevent access by making holes in the structure, for instance. If a hole is made in a structure comprised of the inventive laminate, a destructive element will be activated so as to render material stored in the space no longer valuable or unusable.
• An overlapping drill guard is provided at joins and doors, and electric contacts which function to break the signal circuit when an attempt is made to separate the join are provided inwardly thereof. These electric contacts are conveniently connected in series with the alarm mats, so as to reduce the number of current circuits.
• the inventive laminate can be used, for instance, in the construction of containers or cases for the trans ⁇ portation of valuable items, such as for cash trans ⁇ portation, security containers for use in motor vehi ⁇ cles and aircraft, weapon storage systems, inexpensive bank vaults, etc.
• the inventive laminate can also be used to provide around different containers, localities and spaces a shell which will make unauthorized access impossible without activating an alarm system or a destructive system.
• the inventive laminate may be constructed in various ways.
• the laminate will consist solely of one alarm layer 11 arid one outer sheet or layer, provided that the alarm layer, or mat, is bonded adhesively to the outer layer in an effective and satisfactory manner.
• the laminate may include further layers or sheets of different kinds if so desired.
• the materials used may also vary.
• the laminate will suitably have a thickness of about 5 mm.
• the alarm mat is suitably baked, moulded or glued firmly in the laminate.
• the laminate may also be provided with stiffening means.
• the laminate comprises optical fibres instead of electrically conductive threads
• the remaining, peripheral equipment will, of course, be adapted to the use of optical fibres, and that the above description concerning electric current circuits will, instead, apply to light signal circuits.
