• the internal temperature is limited by thermal insulation produced by light, multi-layer materials of variable density joined together by bonding, or by pins either at the external enclosure or at the internal enclosure.
• thermal insulation materials 17 and 18 bonded to the external enclosure the total thickness calculated is 70 mm, confirmed by tests on similar specimens, so that the internal temperature does not exceed 60 ° C on the contents for a flame temperature of 800 ° C outside for a limited duration of the fire.
• An active refrigeration system not shown, based on pressurized gas in a tank and placed in the external enclosure makes it possible to limit the temperature to a lower value if necessary.
• the enlargement shown in Figure 4 shows some elements of the transport case, according to the invention.
• folding handles 45 facilitating handling and in particular placing the edge of the trunk after loading, and the connection means between the body 36 and the cover 35.
• They consist mainly of bolts 19 tightening two edges of the outer enclosure 16 of the cover 35 and of the body 36.
• a fire seal 39 Protection vis-à-vis flames and hot gases is ensured by a fire seal 39 and by an insert in the form of a baffle 41 which, in addition, can receive a heat-inflating seal in the event of failure of the fire seal 39 In normal use-opening and filling of the trunk, this baffle serves to protect the insulators.
• the internal enclosure also has a body 38 and a cover 37.
• the latter preferably constitutes a single face of the parallelepiped constituted by the internal enclosure 15.
• Connecting means constituted by bolts 44 keep the body 38 and the cover 37 assembled, a seal 43 being inserted between these two elements.
• Figure 4 shows the presence of a metal reinforcement 42 in the shape of a U and placed on the periphery of the body 38, in order to stiffen this internal enclosure 15. It should be noted that the latter is preferably made of a relatively light material such as an alloy.
• the trunk 1 can be used alone for land transport, that is to say road and rail. With reference to FIG. 1 and concerning the container inside which the trunk 1 is located, there are these two main constituent parts which are a base 2B and a cover 2A.
• the base 2B of parallelepiped shape, so as to match the shape of the trunk, also has horizontal and vertical stiffeners 21 on the external surface 22 of this base 2B. Palletizing tunnels 23 are also provided in the lower part of this body 2B to allow the gripping of the entire container by a handling elevator.
• the base 2B and the cover 2A have closure flanges 24 placed at their junction and thus define a joint plane.
• corners 26 which are preferably made of balsa wood, or a very light equivalent wood. They constitute positioning and wedging devices for the trunk 1 placed in the container and make it possible to avoid the degradation of these internal adaptation materials by the pallet tunnels 14 of the trunk 1, during loading and during the transport phases.
• the rest of the interior of the base 2B that is to say the space remaining between the body 2B and the trunk 1, can be filled with a filling and / or internal adaptation material 27 intended to avoid an internal positioning intended to absorb shocks and to thermally insulate. Glass foam can perform these functions.
• the internal adaptation material can also consist of honeycombs, small deformable tubes of composite material thus constituting a structure which absorbs shock by absorbing energy.
• a deep baffle can fulfill this function.
• thermo-inflating joint it is also possible to use, at this joint plane, a "heat-inflating" joint, not shown.
• a "heat-inflating" seal is not effective, from the point of view of sealing, under normal conditions of transport.
• this thermo-inflating joint expands and takes up all the space in which it can expand and thus provides effective thermal insulation for the trunk placed inside the container.
• the assembly of the cover 2A and of the base 2B can be made of a very thick material (3 mm), such as steel E 690 or E 680 with high mechanical characteristics.
• the stiffeners are made of tubes, preferably of rectangular sections and are spaced about 300 mm apart. It is specified that, preferably, the reinforcing sheets 24 do not protrude with respect to the space defined by the external surfaces of the stiffeners 21.
• such a container complies with the standards of the IATA INTERNATIONAL AIR TRANSPORT ASSOCIATION on air containers (Unit Load Device Technical Manual).
• the container can therefore provide quality protection against external attacks to be recorded in an accidental environment, such as that of an air accident. It is specified that such a container can protect one or more fragile object (s) placed inside the trunk, during an impact test carried out at forty meters per second on a lateral face of the container, this speed corresponding to that of a vertical fall from the ground for an incidence of the impact of the aircraft on the envelope of the container of between twenty and thirty degrees.
• FIG. 2 we find the elements of the container, such as the corners 26, the internal adaptation material 27, the reinforcing sheets 24, the pallet tunnels 23 and the stiffeners 21. It is specified that these are perpendicular with respect to each other and with respect to the external surfaces of the air container which is of parallelepiped shape. On the section in section, that is to say the left part of this figure 2, there are around the horizontal stiffeners 21, sling shackles 28. Between the balsa wedge 26 and the internal adaptation material of the glass foam type 27, a housing 30 is provided for a palletization tunnel 14 of the trunk. A screw-nut closure system 29 has also been shown between the two reinforcing sheets 24 of the cover 2A and of the base 2B.

They consist here of elastic pads "RADIAFLEX” 33 marketed by the firm PAULSTRA and screwed elastic shims 49, arranged opposite the reinforcements 46. It is also possible to provide shock absorbers at this level made up of small tubes made of composite material with a high energy absorption capacity. A flange 40, fixed to the cover 35 just above the joint plane, protects the latter ("drop of water" type system).
• the external face of the external enclosure can be equipped with rigid gripping parts making it possible to tilt the boot from the loading position to the transport position, for example by means of a hoist.
