专利说明:
[0001] TECHNICAL FIELD OF THE INVENTION The present invention relates to an intermodal container for storing and transporting solid products packaged or in dry bulk. The intermodal container is a box (preferably a parallelepiped), usually made of steel, provided with a standardized internal wooden floor, used for the storage and transport of goods and reusable for example as a habitat (see Figures 1 to 5) . The intermodal containerized freight transport system is global and enables the safe and efficient movement of goods. [0002] The term "intermodal" indicates that the container can be moved from one mode of transport to another (maritime, river, rail, road) without breaking the load, that is to say without unloading and reloading the contents of the container. The containers each have a unique identification mark governed by ISO 6346; their length generally varies from 8 feet (2.388 m) to 56 feet (17.07 m) and their height from 8 feet (2.438 m) to 9 feet 6 inches (2.9 m). The capacity of the containers is often expressed in units equivalent to twenty feet (capacity equal to a length standard of 6.10 m x width of 2.44 m). [0003] We will call them later the "ISO containers" because they must comply with the ISO requirements in force at the time of their manufacture; for example in transport to allow transport by truck, train, boat and / or barge. Reference may also be made to ISO 668: 1995 (which defines containers of 10, 20, 30 and 40 feet). Indeed, the container was invented in 1956 by Malcom McLean and it has almost never changed. [0004] 3034086 The 20 'foot container, the most used is completely airtight and waterproof thanks to seals. It has rigid walls with at least one door. It is usually used to transport solid goods, seeds or powders that do not need a regulated temperature. Chemicals, electronic machines, craft products, medicines, everyday products, instrument and tissue parts can also be transported there. Many of today's high value-added manufactured products are in containers. The container for solid goods in stainless steel has the following advantages: - high strength, 10 - good resistance to rust and corrosion, - but it requires a significant investment, so it is not common. A container for solid goods can also be made of aluminum, according to two types: 15 - One is the type with steel frame and aluminum plates - The other type all aluminum with only the ends of the frame steel. A container can finally be aluminum. In this case it is light, it is often the case of containers used in the air transport. It has superior rust resistance and good appearance as well as good elasticity. On the other hand, it is expensive to build and lacks solidity. Finally, the most common are corten steel, a material resistant to corrosion and easy to repair. [0005] 25 A traditional container can be at the origin of various nuisances and constraints: Marine pollution During the sinking of a boat carrying containers, the contents of these, their coatings / paints of protection, can spread at sea whereas they may be toxic to the marine fauna and flora, their mere presence at sea when they float, involve a danger of navigation and when they sink and become irrecoverable, cause damage of indefinite duration for the marine fauna and flora , 3034086 3 Land Pollution Due to poor load distribution and / or overweight containers, a truck trailer can be knocked down on the highway, a rail car on a railway track, a pile of containers falling from a river barge or a ship, in a river, causing not only accidents but also land, river and ultimately maritime pollution. A health hazard for workers, consumers 10 The gases used for fumigation, ie for destroying harmful living organisms contained in the wooden floor of the containers and / or the products transported, are particularly toxic for humans by inhalation (hydrocyanic acid, methyl bromide, phosphorus hydride, etc.) or carcinogens (bromomethane, benzene, or 1-2-dichloroethane). [0006] 15 Fumigation is essential to prevent the spread of pests through transport. However, these fumigant gases are sometimes contained without any indication of their presence in the container so that many employees expose themselves to these toxic gases without any protection, without any prior information and without realizing it. In addition, these gases can mix with those released by the transported products and form exploding explosive mixtures on opening of the container. the constraint related to the maintenance of these containers which can sometimes represent 1/3 of the 25 price of the container (floor change, paint ... welding) to be able to guarantee a good seal despite the vulnerability of seals rubber vis-à-vis salt spray) not to mention the financial impact due to its immobilization. The lifespan of a container even if properly maintained does not exceed 10-15 years. [0007] State of the art and its drawbacks 3034086 4 To solve the problem of maritime shipping, the French patent FR 2 971 777 proposes a container convertible into an autonomous floating structure which facilitates its recovery at sea, accelerates it and thus avoids its contents or its coating pollute. This container can be made of polymer or composite material, lightweight materials allowing it to float better. This container is constituted by a stack of n boxes at least one of which is central, the boxes being connected together to form when deployed with respect to each other, a rigid and floating structure having a longitudinal dimension and / or a transverse dimension greater than those of the container in its undeployed position. [0008] However, this container solution consisting of the combination of n boxes involves a compartmentalization of its internal volume which is not suitable for the transport of certain products and does not solve the problems of danger to health, and danger during land transport. supra. [0009] To solve the problem of the distribution of the load within the container, and thus avoid the dangers related to the land transport of containers, the document FR 3 005 938 proposes a container whose length can be modified between a maximum length used for a container. maximum load (for example on a one-way trip) and a minimum length used for a minimum load (for example on the return journey 20 while the container has been emptied of the original merchandise which has been replaced by another less large). This container can also be made of plastic, which facilitates its maintenance. Although this solution appears relatively satisfactory in terms of reducing the dangers associated with the transport itself, it is however tacit on the problems related to the health of workers and consumers. Furthermore, the document EP 1 179 978 proposes a container for maritime transport whose internal volume is divided into a fumigation chamber, in which are arranged the products to be transported and smoking, and a fumigation control chamber. Once the fumigation is carried out, in order to reduce the toxicity of the internal volume of the container, the gases are purified by an absorption bed activated carbon before being discharged to the outside atmosphere by a fan. However, the solution of rejecting these even purified gases in the atmosphere is unsatisfactory from an environmental point of view (risk of filter saturation, poor purification and pollution). DISCLOSURE OF THE INVENTION The invention aims to overcome these drawbacks by proposing a container solution allowing both: easy recovery at sea, secure including in case of falling at sea participation in the reduction of fixed costs related to transport (energy) all 10 mode confused without reducing the commercial speed securing the handling and control personnel (and end user) without any modification of the container in terms of dimensions and handling and transport functions, in order to comply with the standards in force. [0010] To achieve this object, the invention relates to a container, stackable, for the transport of products, comprising: a box-forming portion defining a base and four side walls, secured to each other in a sealed manner, made mainly of plastic material , 20 a sealed closure door of the box, forming with the box when closed on it, a sealed box, a suction system and compression of the gas contained in the closed box, at least one sealed envelope for storing the gases sucked and compressed, 25 secured to the box and forming a wedge flange during transport and float buoy during an immersion of the container. The invention thus defined allows, thanks to the main elements above, to have a relatively light structure and easy maintenance compared to those of steel, while ensuring sanitary safety due to the suction of gases from the internal volume of the caisson, a safer transport due to the rigging of products and easier recovery at sea because of the relative lightness of the container and the presence of buoys. [0011] The invention also has one and / or the following additional characteristics: the suction and compression system for the gases contained in the closed box and / or the sealed gas storage envelope Aspirated and compressed is disposed inside the box - the sealed storage envelope is fixed in a zone of the internal volume of the box where the bag once inflated, is likely to serve as wedging 10 transported products. the sealed storage envelope is removably attached to the interior of the box; the gas suction and compression system comprises a gas analyzer aspirated by the pumping system; the analyzer comprises a comparison unit of the results; method for analyzing aspirated gases with a database listing the results of analysis obtained under similar conditions in the presence of known control elements such as narcotics, and / or a human presence - the bottom wall of the casing includes a integrated weight sensor - the box of the container is obtained by molding 25 - The box is obtained: by molding in its parallelepipedal shape or by molding in a flat shape defining between the side walls and the base, sealed joints allowing a setting volume, volume setting in the parallelepipedic form and then sealing the adjacent walls not bound by a sealed joint - the box comprises at least on its upper wall a solar panel 3034086 - the container comprises corner pieces for stacking the container, and / or a weight sensor such as a strain gauge, and / or a connection system of a solar panel, these parts or gauges or this connection system being comoulés or overmoulded with the box the door is obtained by molding and the frames ensuring its articulation are comoulées or overmolded with the door 10 the container comprises an external access hatch to the internal volume of the chamber likely in an open position, to allow entry into the internal volume of a movable element for detecting the presence of narcotic and / or human presence such as a robot or a small animal. [0012] Other Figures, Features and Advantages of the Present Invention will be apparent from the following nonlimited description, with reference to the accompanying figures which show a non-limiting example of embodiment of the invention and among which: FIGS. 1 to 5 above represent a container according to the state of the art; FIG. 6 is a diagrammatic view of the opening side of the container according to the invention without gas-tight envelope, FIG. 7 illustrates with a view similar to FIG. FIG. 6 shows the same container with 25 gas-tight envelopes inflated by the gas sucked into the internal volume of the container, FIG. 8 represents a schematic perspective view of the container according to the invention, with tearing of the roof giving a glimpse of the system of Figure 9 is an enlargement of Figure 10 centered on the suction system. [0013] According to FIG. 8, the invention relates to an ISO container as defined above, comprising a substantially parallelepipedal main body 1 closed by a door 2, the box defining a bottom wall 3 for supporting the products to be transported, 3034086 8 two side walls 6, 7 including vents (circular insert of Figure 3), an upper wall 5 and a wall 8 opposite an opening closed by the door 2. When closed by the door 2, the body 1 forms a box of container 12. [0014] The container further comprises corner pieces 9 (particularly visible in Figure 4) for securing said container and / or its stacking on other containers (and vice versa) in a conventional manner and in accordance with standards relating to existing containers and in force at the time of manufacture (eg ISO 668: 1995, and in particular Annex A). It thus comprises at least four corner pieces 9 on its upper face, and / or on its lower face. To guarantee a container of this type a relatively light structure, easy maintenance compared to steel, a sanitary safety vis-à-vis fumigation gases, safer transportation and easier recovery at sea, while ensuring strength 15, the container according to the invention comprises a box whose walls are secured to each other in a sealed manner, and mainly made of plastic material, and further comprises as visible in Figures 6 to 9: - a system of suction and compression of the gases 11 contained in the closed box, including 20 - means for conveying the sucked and compressed gases to tight envelopes for storing the sucked and compressed gases 13, integral with the box and forming plugs of the products during transport and buoys when immersing the container in water. [0015] As shown, these envelopes 13 have in the deflated state (not shown) a deflated bag shape, and in the expanded state shown in FIG. 7, that of cushions extending along at least one inner wall of the box (the side walls, upper and lower (under a false floor) in the illustrated example) of the container. These envelopes are in fact fixed in an area allowing it to best stall the products 30 transported without unduly encroaching on the internal volume of the box. For example, on the bottom wall 3 of the container, there will be defined areas where the products may be placed and areas to be left free, since they will receive the bags once inflated. [0016] The envelope is made of an inflatable seamable technical fabric that can be removed from the container. Notches 20, for example T-shaped in cross-section are provided on the inner walls of the container intended to be provided with envelopes and the envelopes comprise tabs 30 which engage firmly in these notches 20. In the example shown , the gas suction and compression system 11 and / or the sealed gas storage envelope are both arranged inside the box. This system may be a venturi 11 or replaced by another device such as a suitable refrigeration system 10 or an agrifood vacuum machine with gas reinjection. The sealed storage envelope is ideally removably attached to the interior of the box so that it can be extracted from the box for cleaning. [0017] The gas suction and compression system can be activated after a fumigation and / or just after the closing of the door for the transport of the container to ensure that these fumigant gases and any other gases released by the products, are trapped in the tubes or cushions 13. [0018] Ideally, the aspirated gases can be analyzed by an analyzer and the analysis results can be accessed from or transmitted outside the container. A resealable orifice may be provided on each sealed envelope for emptying their contents, this opening being able to serve as a connection to a pipe for recovering these gases 25 with a view to their evacuation towards the outside if these gases are harmless, or of their storage / recovery / treatment if they are stale. This analyzer may furthermore comprise a unit for comparing the results of analysis of the aspirated gases with a database listing the results of analysis obtained under similar conditions (identical internal volume, presence of the same number of tubes) in presence of witnesses such as narcotics, and / or a human presence, and sending an alert message when the comparison tends to prove the presence of narcotics or people or animals inside the container. [0019] Interesting technical elements such as solar panels 14 shown schematically, or weight sensors or strain gauges can equip the container. Thus, outside the container (FIG. 8) there may be photovoltaic cells 31 sandwiched by a phosphorescent frame 32. They are connected to elements supplying power to the measuring devices (sensors, gauge, door switch and alarm ): a system equipped with an inverter 33 (FIG. 9) and a battery 34 (FIG 9) enclosed in a box 35 placed inside the container, for example near the ceiling on the opening side. [0020] Since the box 1 and the door 2 are made of mechanically resistant plastics (ideally PET and having a thickness to achieve the required technical performance), the box can advantageously be obtained by molding directly in a single piece. its parallelepipedic shape (without the door) or by molding in a flat shape defining between the side walls and the base, sealed joints (lesser thickness of plastic material for example) allowing a setting volume and volume setting in the form parallelepiped and then sealing the adjacent walls not bound by a sealed joint. By this embodiment, the door can be formed in one piece with the body. In the case of this molding, the corner pieces 9 for stacking the container, and / or a weight sensor such as a strain gauge, and / or the connection system of a solar panel, can be comoulés or overmoulded with the crate. Similarly, the doors and doors of the door (ideally ceramic door frames) will be comoulées or overmoulded with the door. [0021] To allow the entry into the internal volume of a movable element for detecting the presence of a narcotic and / or human presence such as a robot or a small animal, or control devices, the container may further comprise a external hatch 50 (FIG. 8) for access to the internal volume of the box capable of opening in an open position, to let the movable member pass, and, in a closed position, to seal the internal volume . This hatch of about fifty centimeters is accessible by the side wall of the container. It opens via a key-switch which triggers when introduced into the switch, an alarm (for example sound) to avoid theft attempts. Only control personnel are authorized to use it.
