Definitions

• the present invention relates to a device for transporting a container in a vertical position comprising a packaging inside which is arranged a gyroscopic system.
• the invention applies in particular to the field of transport and / or storage of goods, more specifically to the transport of liquid or solid products which must be kept in an upright position during their transportation.
• the products concerned by the invention are in particular, but not exclusively, biological products stored at very low temperature using a cryogenic fluid such as liquid nitrogen.
• a cryogenic fluid such as liquid nitrogen.
• two techniques are mainly known, namely on the one hand hermetically closed containers provided with a system which makes it possible to control the internal pressure and, on the other hand, non-hermetic containers to which the invention relates more particularly.
• non-airtight containers are used for transporting gases with high density at atmospheric pressure, these containers being designed to allow the vapors which they contain or which they produce to escape freely, as they heat up.
• nitrogen can thus be transported in thermally insulated containers without any device ensuring the tightness of the closure.
• the transport container must be kept in vertical position in order to avoid accidental spillage of liquid nitrogen.
• the weight of the metal containers contributes to increasing the cost of transport and, on the other hand, the empty repatriation of the container to the place of origin of the shipment must be organized if the costs to be incurred for the refunds are less than the purchase price of a new unit.
• This deposit system is an important constraint, especially when it comes to long distance shipments or when the sender has to deal with strong seasonal occasional demands governed by biological laws which it is difficult to thwart. This is particularly the case for the reproduction of certain animal species from frozen gametes or embryos.
• the packages are provided with a gyroscopic system, that is to say an internal mechanism allowing the free rotation of the transport container along two orthogonal axes so that, under the effect of its own weight, the container constantly keeps an upright position, regardless of the orientation of the packaging.
• Document FR-A-332.713 describes, for example, a device for transporting biological products, more particularly live yeasts in their feed liquids, comprising such a gyroscopic system.
• the gyroscopic system is integral with a cubic transport packaging and comprises a first outer circle which is mounted so as to be able to rotate, relative to the packaging, around an axis of articulation by means of two pins carried by two opposite sides of the packaging and a second inner circle which is mounted so that it can rotate, around another axis of rotation, inside the first circle by means of two other pins carried by the first circle and arranged in a direction perpendicular to that of the packing pins.
• the two articulation axes of the circles of the gyroscopic system are orthogonal to each other and perpendicular to the faces of the packaging.
• Such devices first of all require time in order to assemble and assemble them, in particular for mounting the first circle of the gyroscopic system secured to the walls of the package, so that such packages are, by their relatively complex design, time consuming and expensive to produce.
• the central container transported by means of such packaging proves to be very sensitive to shocks, in particular to shocks transmitted during transport and / or handling operations, because such shocks collected by the packaging are directly transmitted to the gyroscopic system secured to the walls of the packaging. There is thus a significant risk of deterioration, mainly of the structure of the gyroscopic system and / or of the container which it carries, and consequently of the product transported.
• such packaging must have sufficient rigidity so that the walls can in particular support the weight of the gyroscopic system and of the transport container.
• the invention provides a device for transporting a container which overcomes the drawbacks of the state of the art.
• the invention provides a device for transporting a container comprising a polyhedral packaging inside which is arranged a gyroscopic system intended to hold the container vertically, of the type in which the gyroscopic system comprises a first inner frame which carries the container and a second outer frame, the first inner frame being mounted movable in rotation relative to the second outer frame around a first articulation axis and the second frame being mounted movable in rotation relative to polyhedral packaging around a second axis of articulation orthogonal to the first axis, characterized in that the second axis of articulation extends substantially along one of the diagonals of the polyhedral packaging.
• the transport device has a structure less sensitive to shocks than packaging according to the prior art.
• the device includes shock absorption means arranged between the packaging and the gyroscopic system.
• the gyroscopic system according to the invention is simpler and quicker to arrange in the packaging and can be made with materials which are sufficiently inexpensive that there is no need to deposit them and that the transport device is for single use, that is to say disposable.
• the device according to the invention is simple in design and easy to implement, in particular because the gyroscopic system can be introduced and maintained in the packaging, from which it is independent, in a simple and rapid manner and without putting implemented no tools.
