Description

Isothermal packaging device for thermosensitive products

FIELD OF THE INVENTION The present invention relates to devices for packaging and transporting heat-sensitive products, and more specifically to the isothermal boxes intended to maintain said products under determined temperature conditions.

STATE OF THE ART In the field of logistics, more specifically in the field of transport and storage of products, a number of containers have been developed for the purpose of protecting said products from physical damage. However, products of the food or pharmaceutical type do not only need protection against shock but also need to be kept in stable temperature conditions during transport and / or storage. Indeed, such thermal stability is necessary to prevent the products are damaged and rendered unusable, whether this damage is apparent or not. Such products sensitive to temperature variations are said to be heat-sensitive.

The field of pharmacy is the most representative example of these thermal stability constraints, since the drugs must absolutely be maintained in determined temperature ranges to guarantee their effect. Medicines are usually contained in relatively thin and fragile packages that are not suitable for ensuring the required thermal stability, and it is therefore necessary to gather these drugs in specific containers to both ensure the physical integrity of the drugs as well as as their thermal stability during transport time and / or storage. There are many solutions of isothermal boxes today which make it possible to maintain a particular product in a determined temperature range for a more or less important time. These isothermal boxes, whatever their size, are generally composed of an outer envelope formed for example in cardboard, which defines the external volume of the box, this outer envelope enclosing a number of thermal insulation plates formed from of various materials (such as polystyrene, polyurethane, etc.), these thermal insulation plates being arranged in the outer envelope so as to form a packaging space for the positioning of products, this packaging space being thermally insulated . In addition, there are provided inside the isothermal box housing for receiving thermal stabilizers to maintain determined temperature conditions within the conditioning space, these stabilizers being selected according to the external conditions, including transport. The various arrangements proposed today in the placement of thermal insulation plates and / or the positioning of thermal stabilizers are poorly suited for high volume packaging boxes, several hundred liters. In particular, one of the major disadvantages of large capacity isothermal containers is the thermal stabilization. Indeed, the volume of packaging of the products being important, it is difficult to maintain a homogeneous stabilized temperature within said volume, this being in particular due to the configurations of the containers and the placement of the thermal stabilizers. Another disadvantage of existing isothermal containers concerns their handling both as regards their assembly before placing the heat-sensitive products in the packaging space, but also their handling during the transport phase, in particular when it is necessary to replace thermal stabilizers to guarantee the temperature maintenance of products for a long time. The existing large-capacity isothermal containers also present a number of disadvantages as regards their storage when not in use, but also for their empty transport. An object of the present invention is therefore to provide a product conditioning solution to maintain a given temperature range, this solution to solve at least one of the aforementioned drawbacks. In particular, an object of the present invention is to provide a device for packaging products in isothermal conditions with increased reliability, especially when the isothermal container is of large capacity, with a packaging space of several hundred liters.

Another object of the present invention is to provide a device for packaging products in isothermal conditions whose handling is improved, particularly with regard to assembly and / or disassembly, use during transport, and also storage empty.

SUMMARY OF THE INVENTION To this end, there is provided a product conditioning device intended to maintain said products in a determined temperature range, comprising: a plurality of thermal insulation panels arranged to form a box of parallelepiped shape, said box having a front face, a rear face opposite to the front face, and four perpendicular two by two faces and opposed in pairs and each extending between the front face and the rear face; said front face being movable relative to the peripheral faces so as to form a main opening allowing access to an interior space of the box for the packaging of the products, at least one of the peripheral faces comprising at least one peripheral housing intended to receive at least one thermal stabilization element, the rear face also comprising at least one rear housing intended to receive at least one thermal stabilization element, characterized in that the device comprises at least one rear opening formed along an edge between the rear face and one of the peripheral faces, said rear opening being provided to allow access to the rear housing of the rear face from outside the box, and in that the device comprises a removable closure member for closing said lateral opening.

DESCRIPTION OF THE FIGURES Other features and advantages of the invention will become apparent from the description which follows, which is purely illustrative and nonlimiting, and should be read with reference to the accompanying drawings, in which: - Figure 1 is an exploded view of the various components of the isothermal box according to the invention: - Figure 2 is a perspective view of the isothermal box according to the invention during assembly; - Figure 3 is a perspective view of the isothermal box according to the invention during transport of products.

DETAILED DESCRIPTION OF THE INVENTION As seen in the figures, the packaging device according to the invention comprises a box 1 of parallelepiped shape which has a face for loading the products. This face comprises a shutter member removable from the other faces constituting the box, so as to allow access to the inside of the box that is to say in the packaging space of the products to be maintained in stabilized temperature conditions. The box consists of thermal insulation panels which are arranged relative to each other to form said parallelepiped box. Inside the box is also provided a number of housings arranged to receive thermal stabilizers which are intended to maintain the interior conditioning volume in a determined temperature range, in particular depending on the external conditions of storage and / or transport.

The proposed configuration described in detail below for the insulated box 1 allows access to the housing for receiving the thermal stabilizers without opening the inner space of product packaging. Thus, this makes it possible to limit any thermal disturbances at the level of the products stored inside the box, in particular in case of replacement of the thermal stabilizers during the transport of the insulated box 1. In order to guarantee optimum thermal stability, it is provided in the isothermal box, according to the invention, housing for receiving thermal stabilizers at the face opposite to the loading face, in order to have a maximum of the faces of the box comprising thermal stabilization elements.

In the case of isothermal boxes of large capacity, that is to say having a storage volume of several hundred liters, the loading face of the products is preferably the front face of the box so that the products can be loaded horizontally, at ground level, rather than from above. In this case, there are provided housing for thermal stabilizers on the rear face of the box which is the opposite side to the loading face. According to the invention, a retractable hatch is provided on the rear part of the box which makes it possible to position thermal stabilizers in the housings provided on the rear face of the box without having access to the internal volume of packaging of the products, in particular without having to use the main access way of the box by the front face, which would require to cross the interior space of conditioning. More specifically, the retractable door corresponds to an opening in the box, for example at the side edge between the rear face and one of the side faces of the box. Such an opening, preferably of longitudinal shape, thus makes it possible to insert thermal stabilizers inside the box in the housings provided for this purpose on the rear face. In addition there is provided a shutter member for closing the lateral positioning opening of the rear thermal stabilizers.

Such a configuration therefore allows to provide housing on each of the peripheral faces of the isothermal box 1, these housings being configured to receive thermal stabilizers to be loaded from the front of the box. The front face also preferably comprises housings for receiving thermal stabilizers so that the isothermal box 1 according to the invention may comprise thermal stabilizers on each of the faces that compose it, thus ensuring increased thermal stability, as well as that a homogeneity in the thermal regulation at the level of the products stored in the inner space of conditioning. This configuration is particularly advantageous since it allows a loading of the thermal stabilizers without having to access the inner space of packaging. Indeed, the stabilizers of the peripheral faces can be positioned from the front face. The stabilizers on the front panel are positioned when closing the main access road. And finally, the rear thermal stabilizers are positioned at the rear face using the retractable hatch at the back of the box. We will now describe a particular embodiment of the invention with reference to Figures 1 to 3, the latter being non-limiting, the teachings presented above can be adapted to other particular configurations. Referring to Figure 1, the packaging device shown comprises a plurality of thermal insulation panels for forming the isothermal box 1. This isothermal box 1 has a parallelepipedal shape and comprises a front face 10, a rear face 20 opposite to the front face 10. Moreover, this isothermal box 1 comprises four peripheral faces perpendicular two by two, parallel in pairs, and extending between the front face 10 and the rear face 20. More specifically, the isothermal box 1 comprises a face lower 30 forming the base of the isothermal box, that is to say corresponding to the support face of the isothermal box 1. Opposite this lower face 30 and also extending between the front face 10 and the rear face 20 , there is provided an upper face 40 forming the top of the isothermal box 1. Finally, the isothermal box 1 comprises two opposite side walls 50 and 60 each extending between the face a 10 and the rear face 20 and between the lower face 30 and the upper face 40. In the embodiment shown in Figures 1 to 3, each of the faces constituting the isothermal box 1 comprises housings for receiving a stabilizing element. thermal 80 provided to maintain a stable temperature within the interior of the packaging space for the storage of heat-sensitive products. The thermal insulation panels used to form each of the faces composing the isothermal box 1 can take various forms. For example, it is possible to provide thermal insulation panels with sleeves whose structure makes it possible both to provide the necessary thermal insulation, thermal regulation by receiving thermal stabilizers 80, and also giving the isothermal box resistance. increased mechanics. Referring to Figure 1, the rear face 20, the upper face 40, and the side faces 50 and 60 comprise such a heat insulated duct panel whose structure is as follows. Each of the thermal insulating panels comprises an outer plate (21, 41, 51, 61) intended to form the outer surface of the corresponding face, and thus forming the outer envelope of the insulated box 1. In this respect, it is coated with a protective material, such as kraft or cardboard. This external plate can furthermore have an insulating function. The outer plate can thus be formed of an insulating material coated with a protective material. The insulating material may for example be polyurethane, polystyrene, extruded polystyrene (XPS), polyethylene, or be formed of vacuum panels (VIP) . Each insulated thermal insulation panel also comprises at least one inner plate (22, 42, 52, 62) intended to form the inner surface of each of the corresponding faces, and thus defining the internal space for packaging the products of the 1. Preferably, these internal plates (22, 42, 52, 62) are formed in insulating materials selected according to the desired product storage conditions and temperature maintenance ranges. Such internal insulation plates (22, 42, 52, 62) may for example be formed in materials based on polystyrene, polyurethane, polyethylene, etc. The internal plates may for example be formed based on extruded polystyrene (XPS for "extruded polystyrene"), or be formed of vacuum panels (VIP according to the acronym "Vacuum Insulated Panels"). Finally, each of the insulating thermal insulation panels comprises spacers (23, 43, 53, 63) arranged between the outer plate (21, 41, 51, 61) and the inner plate (22, 42, 52, 62). of the corresponding panel and being arranged relative to each other so as to form sleeves for the housing of thermal stabilizers 80. These spacers (23, 43, 53, 63) preferably have a longitudinal shape and are distributed on the outer plates and internal so as to provide a certain rigidity to the thermal insulation panels considered. Moreover, these spacers (23, 43, 53, 63) also make it possible to ensure an increased mechanical strength of the isothermal box assembly 1 when the thermal insulating panels are assembled with each other in order to form the different faces of the isothermal box 1. This configuration of thermal insulation panels with sleeves with the use of transverse struts is also particularly advantageous for the reception of thermal stabilizers 80 which can have a relatively high weight. Indeed, the sleeves created by the struts form slides within which the thermal stabilizers 80 can be inserted and translated.

Preferably, the spacers are also formed of an insulating material, for example based on polystyrene, polyurethane, polyethylene, etc. According to a preferred embodiment, the insulated thermal insulation panels have a kraft coated polyurethane outer plate, spacers and an extruded expanded polystyrene outer plate XPS.

In the embodiment shown in FIG. 1, the lower face 30 of the isothermal box 1 does not include such a thermal insulation panel with ducts. It is intended to use a single outer panel 31 for forming the support and insulation of the isothermal box 1 without housing to receive thermal stabilizers are provided. For this purpose, the lower face 30 of the isothermal box 1 is generally positioned on a handling element of the isothermal box 1, such as a pallet 2 illustrated in FIG. 3. In this case, it is generally provided with housing for the positioning of thermal stabilizers 80 within the pallet 2 handling so that it is not necessary to provide such housing in the lower face 30 of the isothermal box 1. It is possible, however, to provide that the face The bottom 30 of the isothermal box 1 also comprises one or more insulated thermal insulation panels as presented above. The front panel 10 of the isothermal box 1 could also be in the form of a heat insulating panel which would be positioned resting on the edges of the different peripheral faces (30, 40, 50, 60) of the box isothermal 1.

However, according to the preferred embodiment, illustrated in the figures, the front face 10 of the isothermal box 1 comprises two separate plates 11 and 12 to ensure a closure in two stages of the main access of the isothermal box 1. In Indeed, as illustrated in FIGS. 1 and 2, the front face 10 firstly comprises an intermediate plate 12 intended to be positioned between the different peripheral faces (30, 40, 50, 60) of the isothermal box 1 so as to closing the access to the internal conditioning space delimited by the inner plates (22, 42, 52, 62) and the plate 31 of the peripheral faces and the rear face of the isothermal box 1. Preferably, the surface towards the outside of the intermediate plate 12 of the front face 10 comprises housings 13 provided to receive thermal stabilizers 80, in order to ensure the thermal regulation at the front face 10. Moreover, the front face 10 of the b isothermal unit 1 comprises an outer plate 11 intended to be positioned on the inner plate 12 to cover it and also to cover the accesses to the various housings formed by the sleeves of the thermal insulating plates constituting the peripheral faces of the isothermal box 1 In this respect, the outer plate 11 has dimensions substantially greater than the intermediate plate 12 of the front face 10.

As is apparent from the foregoing description, each of the faces of the insulated box 1 is made from flat thermal insulation panels and independent of each other which greatly facilitates both the handling and storage of the isothermal box 1. In fact, when the insulated box 1 is not used, that is to say when it is not necessary to transport or store heat-sensitive products, then this can be stored or transported in such a way that completely disassembled, the thermal insulation plates being for this purpose simply stacked on top of each other. Such disassembled arrangement allows a volume gain particularly advantageous for storage but also for transporting the elements constituting the isothermal box 1.

The fact that the different faces of the isothermal box 1 consist of flat panels also facilitates its assembly and disassembly. Indeed, as shown in Figure 1, the mounting of the isothermal box 1 consists only of an assembly of the panels relative to each other, and a possible fixation of the assembly to maintain some cohesion.

Thus, it is possible for example to position in a first step the plate 31 forming the lower face, that is to say the base of the isothermal box 1. It is then positioned around this lower plate 31 the thermal insulation panels with sleeves defining the lateral faces and the insulating thermal insulation panel defining the rear face 20. These different panels cooperate with each other and with the lower panel 31 by any suitable fastening means, for example by cooperations of shape between the different panels, or simply by the use of suitable fastening means (glue, screws, etc.). Once the lateral faces 50 and 60 and the rear face 20 are positioned around the lower face 30, the upper face is positioned between the lateral faces 50 and 60 and the rear face thus defining a parallelepipedal box with a single open face. . The thermal insulating panel of the upper face 40, also cooperates with adjacent panels, fixing means may also be provided to maintain these panels. A set of straps 90 can additionally complement or replace any fastening system between the panels. Once this assembly is completed, an isothermal box 1 is obtained as shown in FIG. 2, which presents a main access path to the internal space for packaging the products through the front face of the insulated box 1. As is apparent from FIG. of Figure 2, openings are provided at the edges between the rear face 20 and the side faces 50 and 60 so as to be able to access the receiving sheaths of thermal stabilizers 80 of the thermal insulation panel with sleeves constituting the rear face 20 of the isothermal box 1.

These lateral openings are preferably formed on either side of the rear face 20 but it could be envisaged to form a single passage as long as it guarantees access to the housing formed by the sheaths of the thermal insulation panel. The lateral openings may, for example, be formed directly in the lateral panels forming the lateral faces 50 and 60 of the isothermal box 1. In addition, closure elements 70 are provided for these lateral openings. in such a way as to constitute retractable access hatches for the ducts of the thermal insulating panel of the rear face 20. Such closure elements 70 may, for example, take the form of longitudinal bars (71; 72) having a corresponding shape at the opening formed along the edge between the rear face 20 and one of the lateral faces 50 and 60. More preferably, the longitudinal bars Nales (71; 72) are provided to be positioned flush with the outer faces of the outer panels (51; 61) side faces (50; 60). These lateral openings positioned at the rear face 20 of the isothermal box 1, allow access to the housing thermal stabilizers to be positioned on the rear face. If it is imperative to have at least one retractable hatch at the rear face 20 for the loading and unloading of the thermal stabilizers 80 on the rear face 20 without having to access the internal space of product packaging, it is possible to also provide other retractable hatches in the isothermal box 1 to also facilitate the establishment and removal of thermal stabilizers 80 positioned on the other faces constituting the isothermal box 1. Once the isothermal box 1 has been mounted, it is that is to say when the different lateral faces and the rear face are integral with each other, then the isothermal box 1 is ready to receive the temperature sensitive products intended to be maintained in a determined temperature range.

Access to the various housings intended to receive the thermal stabilizers 80 is very easy, since the housings of the rear face 20 are accessible via one of the two retractable side hatches, after removing one of the longitudinal bars. (71, 72). In the same way, it is simple to position the thermal stabilizers 80 in the sheaths formed on the peripheral faces of the insulated box 1, access to these housings being made from the front face 10 of the insulated box 1. As it is see in Figure 2, the embodiment shown allows to load the thermal stabilizers 80 horizontally which is very advantageous in terms of handling. In fact, the isothermal box 1 presented is intended to condition a large volume of products, the inner packaging space having a volume of several hundred liters. As a result, the dimensions of the isothermal box and the dimensions of the thermal stabilizers are important as is the weight of said thermal stabilizers. It is therefore particularly advantageous to be able to position and remove the thermal stabilizers horizontally rather than vertically. By way of non-limiting example, the isothermal box may have a length and a width of between 1 meter and 4 meters, and a height of 1 meter to 2 meters. The thermal stabilizers can weigh them of the order of 2 kg to 20 kg. Once the thermal stabilizers 80 of the peripheral faces and of the rear face are positioned in the isothermal box 1, the products to be packaged can be placed in the interior of the conditioning space and the front face 10 is then positioned to close this interior space of conditioning. More specifically, the intermediate panel 12 of the front face is positioned to close the main access of the inner space conditioning. As indicated above, the intermediate plate 12 comprises housings 13 for positioning thermal stabilizers 80 so that the front face also comprises thermal stabilization means. Once these thermal stabilizers 80 are positioned in the housing 13 provided on the front face 10, the outer panel 11 of the front face is positioned to completely close the isothermal box 1.

Once all the thermal insulation panels are positioned to form the isothermal box 1, they can be secured by any appropriate means. One can for example use straps 90 as shown in Figure 3. It is of course possible to use any other fastening means that would be suitable. One of the advantages presented by the isothermal box 1 described here is the possibility of being able to replace the thermal stabilizers 80 positioned in the various housings provided inside the insulated box 1 without opening the inner space of packaging receiving the heat-sensitive products. Indeed, if it proves necessary to replace the various thermal stabilizers 80 used in the insulated box 1, simply remove the outer plate 11 of the front to access the housing of both the front and the peripheral faces of the isothermal box. The presence of the intermediate plate 12 at the main access of the interior of the packaging space keeps the inner packaging space closed. In the same way, it is possible to change the thermal stabilizers 80 provided at the rear face 20 through retractable hatches 70 formed at the rear phase 20 of the isothermal box 1. This configuration is particularly advantageous since it allows to guarantee that the product remains thermally insulated, thanks to the various internal insulating panels (12, 22, 31, 42, 52, 62) which define the interior of the packaging space. The structure and the method of assembly proposed for the isothermal box 1 also makes it possible to optimize the preparation time while securing and guaranteeing a better respect of the chain of cold. Indeed, this method of assembly makes it possible, if necessary to separate the time of the assembly operation of the isothermal box 1 from the time of the preparation operation for shipping. It is thus possible to prepare the structure of the isothermal box 1 the day before, to insert the thermosensitive products and to store the isothermal box in a cold room to maintain the temperature, then to insert the thermal stabilizers 80 at the last moment just before the shipping in order to to obtain the longest possible autonomy. The product is protected by the internal thermal insulation plates during the insertion of the thermal stabilizers 80 into their respective housings. The housings being preferably formed by sheaths arranged on the various thermal insulation panels constituting the faces of the isothermal box 1, it is preferable to use thermal stabilizers 80 having a longitudinal shape so as to facilitate their sliding in these dwellings. . Furthermore, if the isothermal box 1 is of very large size, it is possible to use thermal stabilizers 80 coupled together by any means of connection thus making them integral with each other, especially for their removal from said housing since only one end of the sheath. The thermal stabilizers 80 are generally rigid or semi-rigid briquettes formed of a plastic envelope (for example high density polyethylene - HDPE) containing a eutectic agent to ensure the desired thermal stabilization function.

The reader will understand that many changes can be made without materially escaping the new lessons and benefits described here. Therefore, all modifications of this type are intended to be incorporated within the scope of the presented packaging device.
