Device which is used to transport a container in the vertical position, comprising packaging containing a gyroscopic system

The present invention relates to a device for transporting a container in an upright position comprising a package within which is arranged a gyroscopic system.

The invention applies in particular to the field of transport and / or storage of goods, namely the carriage of liquids or solids to be kept upright during transport.

The products concerned by the invention are particularly, but not exclusively, organic products stored at very low temperature with a cryogenic fluid such as liquid nitrogen.

In the field of containers for the transport of liquefied gases, mainly two techniques are known namely on the one hand the tightly closed containers equipped with a system that allows to control the internal pressure and, secondly, non-airtight containers which specifically relates to the invention.

These non-airtight containers are used for transport under atmospheric pressure gas whose density is high, these containers being provided to allow free escape the vapors they contain or produce as and when they change.

For example, nitrogen may well be transported in thermally insulated containers and lacking device sealing of the closure. However, container or shipping container should in return be strictly maintained in an upright position to prevent spillage of liquid nitrogen.

Due to its simplicity, this type of container is widely used especially for the transport or storage of biological materials requiring storage at very low temperatures.

However, most of these known containers and packing materials are metallic and are made from materials whose high cost makes it prohibitive any disposable use.

In addition, for the transport of biological materials whose commercial value is very low, shipping generated by the use of such containers are very important.

On the one hand, the weight of metal containers helps to increase the cost of transport and, secondly, to return the empty container to the place of origin of the shipment must be organized if the expenses incurred for the restitution are lower than the purchase price of a new unit.

This deposit system is a major constraint especially when it comes to distant expeditions or when the sender has to face strong seasonal ad hoc requests governed by biological laws it is difficult to thwart. This is particularly the case for the reproduction of some animals from gametes or embryos frozen.

Moreover, when the transport is by a courier service, the containers are vulnerable and remain vulnerable to shocks and frequent reversals, especially when it comes to smaller less stable units. But the total or partial loss of coolant diminishes the shelf life of the goods or causes irreparable destruction.

Known in the prior art various solutions have been proposed to overcome these drawbacks and implement in particular gyroscopic systems.

In these solutions, the packaging is provided with a gyroscopic system, i.e. an internal mechanism to allow free rotation of the transport container along two orthogonal axes so that, under the effect of its own weight, container constantly keeps an upright position and this regardless of the orientation of the package.

FR-A-332 113 and the Addition of Invention Patent no. 2170 describe, for example a biological product transport device, more particularly live yeast in their foster liquids, comprising such a gyroscopic system.

More specifically, the gyroscopic system is integral with a cubic transport packaging and comprises a first outer ring which is rotatably mounted relative to the package, about a hinge axis by means of two trunnions carried by two opposite faces of the packaging and a second inner ring that is rotatably mounted around a further axis of rotation, inside the first circle by means of two other trunnions carried by the first circle and arranged in a direction perpendicular to that of the pins of the package.

Thus, the two articulation axes of the gyroscopic system circles are mutually orthogonal and perpendicular to the surfaces of the packaging.

Such devices firstly require time to carry out their installation and assembly, including mounting the first circle of solidarity gyroscopic system of walls of the package, so that such packages are, by their relatively complex, lengthy and costly design to achieve.

Then they have another disadvantage that their repatriation because of their weight and their empty volume is very expensive since the gyroscopic system being attached to the packaging, it should be repatriated with ceiui it.

This disadvantage of the volume also appears when the packages are not used, requiring large storage areas.

Not least, the central container transported by means of such packages is very sensitive to shocks such shocks transmitted during transportation and / or handling, because such shocks received by the packaging are directly transmitted to the gyroscopic system solidarity with the walls of the package.

There is thus a significant risk of damage, mainly the structure of the gyroscopic system and / or the container which it carries, and therefore the product being transported.

Finally, such a package must be rigid enough so that the walls can support the weight of such gyroscopic system and the transport container.

The invention provides a device for transporting a container which allows to overcome the drawbacks of the prior art.

For this purpose, the invention proposes a device for transporting a container having a polyhedral-shaped casing inside which is arranged a gyroscopic system intended to keep the receptacle upright, of the type in which the gyroscopic system comprises an inner first frame which bears the receptacle and an outer second frame, the inner first frame being mounted mobile in rotation relative to the outer second frame about a first hinge axis and the second armature being rotatably mounted with respect to the polyhedral packaging about a second axis orthogonal to the first hinge axis, characterized in that the second hinge axis extends substantially along one of the diagonals of the polyhedral packaging.

Thanks to the invention, the conveying device has a structure less sensitive to shocks than the packs of the prior art. Preferably, the device includes means for shock absorption provided between the package and the gyroscopic system.

Advantageously, the gyroscopic system according to the invention is simpler and faster to match the package and can be manufactured with enough cheap materials so that it is not necessary to record and that the transport device to be single use, i.e. disposable.

Moreover, the device according to the invention is simple in design and easy to implement, particularly as the gyroscopic system can be introduced and maintained in the package, which is independent, simple and quick manner and without putting out any tools.

The time of preparation of the package prior to its shipment is significantly reduced compared with the solutions of the prior art.

In addition, the transport device according to the invention can be stored in the disassembled position generally flat so as to occupy a considerably reduced volume.

In the following description, identical reference numbers, or the like, designate identical parts or have similar functions.

By convention, the terms "inner", "outer" denote elements close to the container and close the package directions and "horizontal", "vertical" and "horizontal" are given by the system (L, V, T) of Figure 1.

There is shown in Figure 1, a transporting device 10 comprising, vertically from bottom to top, a polyhedral shape or packaging box 12 in which may be received a gyroscopic system 14 for holding vertically a container 16 .

The polyhedral packaging 12 is preferably of parallelepiped shape, particularly of cubic shape.

The polyhedral packaging 12 includes a lower horizontal face 18, an upper horizontal side open loading 20 and four vertical sides 22, each of the side faces 22 being orthogonal to the faces that are adjacent and parallel to an opposite side face.

The package 12 thus defines an internal volume 24 which is delimited downwards by the lower surface 18 forming a bottom, laterally by the four vertical faces 22 and upwardly by the upper face 20 which is open to allow filling of the packing 12.

In known manner, the upper face 20 is, after filling the volume 24 can be closed by folding inwards the two flaps 26, alternatively by a not shown removable cover.

The container or crate 12 comprises eight vertices 28 each defined by the intersection of three faces of the parallelepiped.

The packaging also comprises four inner corners 30 each of which is bounded by the intersection of two consecutive side faces 22.

In such a package 12, a diagonal D is defined by a straight line joining two vertices 28 do not belong to the same face of the parallelepiped.

The package thus has four vertical diagonal of which is illustrated in FIG 1.

The package 12 illustrated in Figure 1 is a cube forming a crate which is preferably made of cardboard but may also be made of other materials and other polyhedral shapes, e.g., rectangular parallelepiped or based 18 "hexagonal".

Figures 1 and 3 respectively represent the gyro system 14 in the use position and storage position, that is to say advantageously flat.

As can be seen in these figures, the gyroscopic system 14 comprises a first inner frame 32 capable of carrying the container 16 and a second outer frame 34.

The inner first frame 32 is rotatably mounted with respect to the outer second frame 34 about a first hinge axis A1 and the second outer frame 34 is rotatably mounted relative to the package 12 about a second axis A2 orthogonal to the joint first articulation axis A1.

The two axes A1 and A2 here are perpendicular and concurrent.

The second outer frame 34 is a flat ring and the second joint axis A2 is located in the plane of this ring 34.

More specifically, the outer second frame 34 is a substantially ring-shaped ellipse whose large axis is substantially coincident with the second hinge axis A2.

The inner first frame 32 is a flat ring of circular shape and the first hinge axis A1 is located in the plane of this ring 32.

In addition, the first joint axis A1 is substantially coincident with the minor axis of the ellipse forming the second outer frame 34.

The transport device 10 comprises support means of the gyro system 14 including the timing of the gyro system 14 in the package 12.

According to a first embodiment illustrated in Figures 1 to 3, the carrying means 14 of the gyroscopic system are constituted by a frame 36 on which the elliptical outer frame 34 is rotatably mounted around said second hinge axis A2.

The supporting frame 36 is a planar frame and is constituted by tubular sections preferably made by plastic molding in one piece as the plates 32 and 34.

The supporting frame 36 comprises two parallel and opposed uprights vertical 38 and horizontal 39 which together form a rectangle with two diagonally opposite corners are "truncated" by two arms 40, parallel and opposite, which form an acute angle with respect to posts 38, 40, here substantially equal to 45 °.

The branches 40 are means 42 for articulation of the elliptical frame 34 relative to the carrier frame 36 which, as can be seen in Figure 2, is fixed relative to the package 12.

The means of articulation 42 of the elliptical frame 34 along the axis A2 relative to the frame 36 are for example formed by pins or other appropriate means.

Similarly, there are provided known means of articulation 44 of the circular inner ring 32 relative to the outer elliptical frame 34 along the axis A1.

In known manner, the gyro system 14 is intended to maintain the container 16 to the vertical, in particular during transport and / or handling operations in which the package 12 may for example be turned in any orientation or any shocks .

The container 16 is advantageously a cryostat, i.e. a thermally insulated container for holding liquids or solids, for example biological products, at low temperature for a given through a cryogenic fluid duration, such as the liquid nitrogen.

The container 16 here comprises an outer body 46 which is preferably made of a thermally insulating material such as polystyrene or polyurethane and which centrally comprises a housing open upwardly and sealed a cap 48.

Housing (not shown) of the external body 46 of the container 16 is eg able to receive an insulating inner bulb (not shown) of the type that has a double wall separate glass by a vacuum to hold for a fixed term and a given temperature the organic products it contains, such a lamp is known commercially under the name bulb "thermos" (registered trademark).

Along a horizontal cutting plane, the outer cylindrical body 46 of the container 16 is of generally circular section.

The body 46 includes a bottom portion 50 of substantially equal diameter D1 to the diameter of the circular ring 32 and which is connected to an upper portion 52 of greater diameter D2 to the diameter D1, by a shoulder 54 facing downwards for positioning the circular ring 32 along the outer wall of vessel 16.

Advantageously, the container 16 and the inner first frame 32 comprise complementary means so as to allow the insertion as a "vertical" race fitting perpendicular to the plane of the circular ring 32, then the locking of the container 16 in the circular ring 32 in the end fitting race.

According to the first embodiment of the gyroscopic system 14 illustrated in Figure 3, the container 16 can be pushed vertically downwards easily in the circular ring 32 before the transportation configuration of the system 14. In the absence of a 39 branches of the support frame 36 can hinder the fitting operation.

Figure 4 shows more particularly a first embodiment of such a container 16 having complementary means for the circular ring 32 making a bayonet mount.

Specifically, the circular ring 32 comprises lugs 56 which extend radially inwardly of the ring 32 and the bottom 50 of the container 16 has two grooves 58 arranged symmetrically with respect to the central vertical axis and one is illustrated.

Each groove 58 comprises a first guide section 60 which extends vertically and rectilinearly and that extends, at its upper end, a second horizontal lock segment 62 forming a complementary detent lugs 56 of the circular ring 32.

Thus, the lugs 56 being coincident with the guide sections 60 of the grooves 58, the container 16 is fitted vertically from top to bottom in the circular ring 32, then the lock is obtained by rotation of the container 16 so as to penetrate the lugs 56 in the notches or latching sections 62.

The initial introduction of the container 16 in the circular ring 32 is facilitated by the end chamfer forming the lower profile of the lower portion 50 of container 16.

2 shows the transport device 10 in the transport configuration, that is to say, the configuration in which the sub-assembly constituted by the support frame 36 and the gyro system 14 in which there is mounted the container 16, is arranged in the interior volume 24 of the polyhedral packaging 12, shown in silhouette.

According to the invention, the second hinge axis A2 of the gyroscopic system 16 extends substantially along the diagonal D of the package 12.

The gyro system 14 can be arranged in the interior volume 24 of the package 12 according to any one of four diagonals.

Then, regardless of the storage or transport position of the package axis A2 is always oriented in a diagonal and the container is upright.

Thus the supporting frame 36 is arranged in the package 12 such that the horizontal bars 39 extend parallel to the sides and bottom 18 and upper 20, so that the uprights 38 are received without play in two interior angles of 30 12 opposite the package according to diagonally so as to calibrate the subset in the package 12.

It is particularly advantageous that the package 12 can absorb some of the shock and vibration without these being transmitted to the gyroscopic system 14 by the support frame 36.

Advantageously, the support frame 36 does not extend in both upper and lower peaks 28 opposed along a diagonal axis of articulation A2, so that the shocks in this direction are not transmitted, or transmitted bit, sub subassembly formed by the frame 36 and the gyroscopic system 14.

In variant not shown, the support frame 36 includes four branches 40 of angles so that the frame 36 does not include any part which extends in one of the vertices 28 of the package 12.

Thus, in case of fall, for example, the corners of the package 12 corresponding to the peaks 28 are susceptible to deformation by crushing of the carton, without however that the shock wave is directly and fully transmitted to the gyro system 14 and / or the container 16.

The deformation capacity of the corners of the package 12 is made possible by the arrangement recessed inwardly of the package 12 of the legs 40 of the support frame 36, and by the choice of material used for the package 12.

Thanks to the invention, the container 16 is better protected against shocks, particularly lateral impact, that is to say according to one of the faces 22 of the package 12, with respect to the prior art in wherein one of the hinge axes of the system was secured to the faces.

In fact, no shock on a lateral face is transmitted directly to the gyroscopic system which no axis A1, A2 is orthogonal to any of the faces of the package 12.

Preferably, the supporting frame 36 is capable of deforming to absorb shock and comprises for example recesses in its structure, as in the horizontal bars 39, to give it a capacity for elastic deformation, especially in the vertical direction and surplus to reduce its weight.

Advantageously, the support frame 36 comprises additional means for shock absorption which are interposed generally between the frame 36 and the package 12.

Such means are not shown for the first embodiment.

The supporting frame 36 can thus be provided with shock absorbing means such as slotted foam cylindrical sleeves which are mounted on the uprights of the frame 36 so as to be interposed between the frame 36 and the package 12 in the corners 30 .

Figures 5 to 7 show a second preferred embodiment of the carrying means of the gyro system 14 which will now be described by comparison and analogy with the first embodiment illustrated in Figures 1 to 3.

As can be seen in Figure 5, the carrier means 14 of the gyroscopic system comprise two identical parts diagonally opposite each bearing 64 of the articulation means of the second outer frame 34 in the form of elliptical ring.

Specifically, each intermediate piece carrier 64 comprises a base or body 66 of generally triangular shape which bears on the one hand the articulation means and, on the other hand, three positioning arms 68 arranged in a trihedron which each extend from one of the peaks of the triangular base 66.

Thus, each arm 68 is provided to extend in a direction parallel to the intersection of two faces of the packing case 12.

The means of articulation of the cam ring 34 relative to the carrier means, so compared to the package 12 along the axis A2 of articulation are constituted for example by a pin 70 integral with the second outer frame 34 which is received in a complementary recess 72 of the base 66 of the intermediate member 64.

Advantageously, the assembly of the cam ring 34 with the base 66 of the intermediate member 64 is realized by elastic fitting of the pin 70 in the manner that the connection housing can be carried out simply and quickly.

The shock absorbing means represented are constituted by cylindrical sleeves 74 which are preferably made of foam or other resiliently deformable material.

The use of such cylindrical sleeves 74 is particularly advantageous in the case of a single use disposable device. Indeed they can be obtained economically by cutting a tubular profile of expanded foam.

Each cylindrical sleeve 74 has at one end a bearing face 75 and at least in the opposite side of its other end a hole 76 for receiving, for example by fitting, one of the positioning arm 68 of the carrier member 64.

6 shows, prior to its arrangement in the package 12, the subassembly constituted by the gyroscopic system 14 and the carrier means after assembly of each intermediate piece 64 with the cam ring 34 and the cylindrical sleeves 74 dampers.

Advantageously, the container 16 can be mounted by fitting into the circular ring 32 of the gyroscopic system 14 after the arrangement of the subset operation in the package 12 so as to obtain the transport configuration shown in Figure 7 .

According to the invention, in the transport configuration, the second hinge axis A2 of the gyroscopic system 14 extends substantially along a diagonal D of the package 12.

Each of the intermediate parts bearing 64 is arranged inside one of the two vertices 28 of the package 12 opposed along said diagonal D corresponding to the second hinge axis A2.

Preferably, the base or plate 66 of the part 64 extends in a plane perpendicular to said diagonal and each of the positioning arm 68 and the associated cylindrical sleeves 74 extends along one of the three edges of the interior angles the corresponding top 28.

The length of the sleeves 74 is such that their sides with the free ends 75 abut against the side faces in facing relation so as to ensure the wedging of the part 64 in the body 12.

Thanks to the invention, the container 16 is better protected against shocks including side impact that is to say according to one of the faces 22 of the package 12.

The sleeves 74 constitute shock absorbing means which are interposed between the carrying means formed by the parts 64 and the package 12.

Preferably, the elliptical ring 34 is elastically deformable to increase the capacity of shock absorption of the device.

8 shows a second embodiment for the fitting and locking the container 16 forming a cryostat in the circular ring 32 of the gyroscopic system 14.

In this example, the locking of the receptacle 16 in the inner first frame 32 is obtained, after vertical fitting by elastic deformation of said first armature 32 so that the frame 32 formed by the circular ring is automatically positioned in a groove in 78 additional locking of the container 16.

The container 16 and the circular ring 32 comprise similar complementary means, namely at least one radial lug 56 of the ring which projects into the straight section of guide 60 in a vertical groove 58 during the fitting of the race container by an up and down movement.

More specifically, the container 16 comprises a lower cylindrical portion 50 including a control portion 80 has, in section along a horizontal plane, and a noncircular cross section such as oval whose perimeter is substantially equal to the diameter of the circular ring 32 of so as to cause elastic deformation of said ring at the vertical fitting of the container 16.

For a container 16 made according to the first or second embodiment described above, tests have shown that there may be for specific conditions determined, a non-zero risk of damage to the insulating bulb.

These special conditions exist for the case of a fall during which a shock would occur on the package 12 before the gyroscopic system 14 has not been able to bring the container 16 substantially vertically so that the container 16 is at the moment of impact in a generally horizontal position, that is to say, forming an acute angle with the central vertical axis.

In such position of container 16, if a shock wave is to be transmitted by the circular ring 32 to the outer body 46 of the container 16, the forces exerted are then not distributed symmetrically about the entire circumference of the circular ring 32, but only on a portion thereof, unlike the case wherein at the moment of impact the container 16 is upright.

Therefore, there is a risk that in the vicinity of the circular ring 32, a shock wave can, in propagating through the outer body 46 made of polystyrene, be transmitted to the bulb, in particular the vertical walls forming the cylindrical body of the cartridge.

However, in such an insulating bulb, the cylindrical section double wall glass is more sensitive to shocks than are the top or the bottom or base of the bulb which, because of the manufacture by blow molding, have a thickness substantially higher.

Therefore, when the circular ring 32 is positioned on the outer body 46 vertically on the portion of the cylindrical body formed by the side walls of the bulb is increased in these specific conditions, the risk of transmission of shocks to a zone the most fragile of the insulating bulb.

To improve the protection of the bulb can be provided according to an embodiment not shown, to interpose between the inner wall of the container defining the housing 16 and the insulating bulb means for absorbing a wave shock and / or limit the spread to insulating bulb.

Advantageously, it is for example possible to inject inside the container 16 a polyurethane foam to fill the space between the bulb and the inner wall of the outer body 46.

After curing, the polyurethane foam forms a layer of material capable of absorbing all or part of the shock wave. In addition, the polyurethane foam immobilizes and stalling the insulating bulb housing, such a bulb obtained blow having no background or base level on which it can be placed vertically into the slot.

Thus, it overcomes the accuracy requirements on the tolerances of the respective ribs of the insulating bulb and complementary recess of the container 16, that is to say of two components made of such material and of manufacturing processes for where such precision is difficult to achieve.

9 illustrates in detail a third example of embodiment in which the inner frame 32 previously formed by the circular ring is integrated into the container 16 so as to improve shock absorption and protection of the insulating inner bulb.

The container 16 comprises an external cylindrical body 46 which is generally formed by two half-shells 45 recessed which, after assembly, internally delimit a housing 47 in which is received an insulating inner bulb 82.

The two half-shells 45 are preferably made by molding polystyrene and are symmetrical along a vertical plane containing the central vertical axis of the container.

The container 16 is closed, not hermetically by a plug 48 which is housed in a recess 49 of complementary shape that the external body 46 comprises in its upper horizontal side.

The body 46 comprises, symmetrically on each of the vertical edges of the shells 45, complementary profiles which, after assembly of the half shells 45 form the vertical groove 58.

As before, the container 16 is designed to be inserted vertically upwards, here in the elliptical ring 34 of which the container 16 is fixed, for example by snap-fastening or elastic interlocking.

The inner frame 32 comprises a horizontal top portion 31 which is received in a complementary cavity 92 that internally comprises the upper part 52 of the body 46 of each half-shell 45, and comprises two diametrically opposite vertical arm 33 integral with each end of the portion 31 of the armature 32.

The arms 33 extend vertically downwardly through the outer body 46 of the container 16 outside which they extend in the upper section 57 of the groove 58.

The arms 33 have at their lower end means 35 that are complementary to articulation means carried by the outer armature 34.

The articulation means along the axis A1, which carries the outer frame 34, are for example constituted by pins (not shown) which extend radially in the manner of lugs 56, inside the elliptical ring 34 and on which are fitted the complementary means 35 of the arms 33 of the inner frame 32.

The groove 58 preferably has a lower straight portion 59 enlarged to facilitate the vertical fitting of the receptacle 16 in the cam ring 34 and which extends a guide section 60 of frustoconical shape which tapers upwardly to drive the articulation means of the cam ring 34 in axial coincidence with the complementary means 35 of the arms 33, which are in form of an open ring down.

Advantageously, the arms 33 have elasticity in the radial direction and can be elastically deformed in the upper portion 57 of the groove 58 so as to filter a part of the shock wave.

The insulating bulb 82 comprises here vertically from top to bottom, a neck 84 defining an upper opening 86 to allow the introduction of organic products and of the cryogenic fluid in the interior volume that laterally delimits a body 88, generally cylindrical, formed by a double glass wall separated by an empty and closes a bottom or base 90.

The horizontal portion 31 of the armature is centrally perforated to allow the passage with radial play of the head 84 of the ampoule 82.

The inner frame 32 is advantageously secured to the upper portion of the outer body 46 of the container 16 so as to avoid such a shock wave is transmitted to the side walls of the insulating bulb.

The axis A1 of articulation of the inner frame 32 forming a sub-assembly with the container 16 relative to the elliptical outer frame 34 is arranged vertically at a substantially equal height of the body 46 of the container 16 that in the exemplary embodiments precedents.

Of course, as has been described above, the polyurethane foam may be injected to form a shock absorbing layer interposed between the insulating bulb 82 and the housing 47 of the receptacle 16 and allowing the timing of the bulb 82 in the housing 47.

Advantageously, the conveying device 10 according to the first or second embodiment is a disposable device of low manufacturing cost for a disposable use.

In addition, in the storage configuration, the device 10 is of small dimensions, in particular the gyroscopic system 14 which is then substantially flat.

Alternatively, after receiving the package 12, the transport device 10, in particular the gyroscopic system 14 arranged in the package 12, could be disassembled and packed temporarily in the storage position, prior to its return to low cost batch comprising several devices.

The arrangement along a diagonal D allows, for given dimensions of the cubic box, to have one part of an outer frame 34 of the gyroscopic system of the largest possible dimension along the major axis of the ellipse and, on the other hand, a larger vessel.

Thus, the exterior armature has a greater ability to deform elastically and thus protect the container 16 from impact.

The transport device according to the present invention applies more particularly to the transport of biological products, such as gametes or embryos, which are stored at very low temperature by a cryogenic fluid such as liquid nitrogen for a specified time sufficient to their delivery.
