- isothermal boxes which make it possible to maintain a particular product in a determined temperature range for a more or less important time.
- These isothermal boxes 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 .
- thermal stabilizers to maintain determined temperature conditions within the conditioning space, these stabilizers being selected according to external conditions, including transport.
- German utility model published on September 6, 2001 under the reference DE 201 08 553 describes an example of an isothermal box that makes it possible to keep products cold, in particular thanks to thermal stabilizers that it integrates into its structure.
- This isothermal box has a particular arrangement, low volume, allowing it to be portable through a handle.
- thermal stabilization 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.

- 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.
- 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.
- 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.
- 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 the inner packaging space. 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.

- straps 90 may be used as shown in FIG. figure 3 . It is of course possible to use any other means of attachment 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 makes it possible 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 conditioning 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 insulation plates thermal internal the time of the insertion of the thermal stabilizers 80 in their respective housing.
- 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.
- a plastic envelope for example high density polyethylene - HDPE

Description
La présente invention concerne les dispositifs de conditionnement et de transport de produits thermosensibles, et plus précisément les boites isothermes destinées à maintenir lesdits produits dans des conditions de température déterminées.The present invention relates to devices for packaging and transport of thermosensitive products, and more specifically the isothermal boxes for maintaining said products under determined temperature conditions.
Dans le domaine de la logistique, plus précisément dans le domaine du transport et du stockage de produits, il a été développé un certain nombre de conteneurs ayant pour objet de protéger lesdits produits de dommages physiques. Toutefois, des produits de types alimentaires ou pharmaceutiques n'ont pas uniquement besoin d'une protection contre les chocs mais nécessitent également d'être maintenus dans des conditions de température stables pendant leur transport et/ou stockage. En effet, une telle stabilité thermique est nécessaire pour éviter que les produits ne soient endommagés et rendus inutilisables, que ce dommage soit apparent ou non. De tels produits sensibles aux variations de température sont dits thermosensibles.In the field of logistics, more specifically in the field of transport and storage of products, it has been developed a number of containers 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.
Le domaine de la pharmacie est l'exemple le plus représentatif de ces contraintes de stabilité thermiques, puisque les médicaments doivent absolument être maintenus dans des plages de température déterminées pour garantir leur effet. Les médicaments sont généralement contenus dans des emballages relativement fins et fragiles qui ne sont pas adaptés pour garantir la stabilité thermique requise, et il est donc nécessaire de rassembler ces médicaments dans des conteneurs spécifiques permettant à la fois de garantir l'intégrité physique desdits médicaments ainsi que leur stabilité thermique au cours du temps de transport et/ou stockage.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.
Il existe aujourd'hui de nombreuses solutions de boites isothermes qui permettent de maintenir un produit particulier dans une gamme de température déterminée pendant un temps plus ou moins important. Ces boites isothermes, quelle que soit leur taille, sont généralement composées d'une enveloppe externe formée par exemple dans du carton, qui définit le volume externe de la boite, cette enveloppe externe enfermant un certain nombre de plaques d'isolation thermique formées à partir de divers matériaux (tels que du polystyrène, du polyuréthane, etc.), ces plaques d'isolation thermique étant agencées dans l'enveloppe externe de manière à former un espace de conditionnement pour le positionnement de produits, cet espace de conditionnement étant isolé thermiquement. Par ailleurs, il est prévu à l'intérieur de la boite isotherme des logements permettant de recevoir des stabilisateurs thermiques pour maintenir des conditions de température déterminées à l'intérieur de l'espace de conditionnement, ces stabilisateurs étant choisis en fonction des conditions extérieurs, de transport notamment.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 . Furthermore, it is provided inside the isothermal housing housing for receiving thermal stabilizers to maintain determined temperature conditions within the conditioning space, these stabilizers being selected according to external conditions, including transport.

Toutefois, les divers agencements proposés aujourd'hui dans le placement des plaques d'isolation thermique et/ou le positionnement des stabilisateurs thermiques sont peu adaptés pour les boites à grand volume de conditionnement, de plusieurs centaines de litres. -However, 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. -
En particulier, l'un des inconvénients majeur des conteneurs isothermes à grande capacité réside dans la stabilisation thermique. En effet, le volume de conditionnement des produits étant important, il est difficile de maintenir une température stabilisée homogène à l'intérieur dudit volume, ceci étant notamment dû aux configurations des conteneurs et au placement des stabilisateurs thermiques.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.
Un autre inconvénient des conteneurs isothermes existants concerne leur manutention aussi bien en ce qui concerne leur montage avant de placer les produits thermosensibles dans l'espace de conditionnement, mais également leur manutention pendant la phase de transport, en particulier lorsqu'il est nécessaire de remplacer les stabilisateurs thermiques pour garantir le maintien en température des produits pendant une longue durée.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.
Les conteneurs isothermes de grande capacité existants aujourd'hui présentent également un certain nombre d'inconvénients quant à leur stockage lorsqu'ils ne sont pas utilisés, mais également pour leur transport à vide.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.
Un but de la présente invention est donc de fournir une solution de conditionnement de produits pour les maintenir dans une plage de température déterminée, cette solution permettant de résoudre au moins l'un des inconvénients précités.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.
En particulier, un but de la présente invention est de proposer un dispositif de conditionnement de produits dans des conditions isothermes présentant une fiabilité accrue, notamment lorsque le conteneur isotherme est de grande capacité, avec un espace de conditionnement de plusieurs centaines de litres.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.
Encore un but de la présente invention est de proposer un dispositif de conditionnement de produits dans des conditions isothermes dont la manutention est améliorée, en ce qui concerne notamment le montage et/ou démontage, l'utilisation en cours de transport, et également le stockage à vide.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 empty storage.
A cette fin, on propose un dispositif de conditionnement de produits destin à maintenir lesdits produits dans une plage de température déterminée selon la revendication 1. Il comprend
- une pluralité de panneaux d'isolation thermique agencés pour former une boite de forme parallélépipédique, ladite boite ayant une face avant, une face arrière opposée à la face avant, et quatre faces perpendiculaires deux à deux et opposées deux à deux et s'étendant chacune entre la face avant et la face arrière ;
- ladite face avant étant mobile par rapport aux faces périphériques de manière à former une ouverture principale permettant un accès à un espace intérieur de la boite pour le conditionnement des produits,
- au moins une des faces périphériques comprenant au moins un logement périphérique destiné à recevoir au moins un élément de stabilisation thermique,
- la face arrière comprenant également au moins un logement arrière destiné à recevoir au moins un élément de stabilisation thermique,
Au moins l'une des faces périphériques comprend au moins un panneau d'isolation thermique à fourreaux orienté de sorte que le logement périphérique formé par le fourreau soit accessible depuis l'ouverture principale de la boite.
La face avant comprend une plaque intermédiaire destinée à être positionnée entre les quatre faces périphériques afin d'obturer l'accès à l'intérieur de la boite tout en laissant libre l'accès au logement périphérique de la face périphérique.
La plaque intermédiaire comprend au moins un logement avant destiné à recevoir au moins un élément de stabilisation thermique l'accès audit logement avant étant prévu à la surface de la plaque intermédiaire destinée à être orientée vers l'extérieur de la boite.To this end, there is provided a product conditioning device for maintaining said products in a temperature range determined according to
- 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 faces two by two and opposite two by two and each extending between the front and the back side;
- 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 for receiving at least one thermal stabilizing element,
At least one of the peripheral faces comprises at least one insulated thermal insulation panel oriented so that the peripheral housing formed by the sleeve is accessible from the main opening of the box.
The front face comprises an intermediate plate intended to be positioned between the four peripheral faces in order to seal access to the inside of the box while leaving free access to the peripheral housing of the peripheral face.
The intermediate plate comprises at least one front housing for receiving at least one thermal stabilizing element access to said front housing being provided on the surface of the intermediate plate intended to be oriented towards the outside of the box.
Les panneaux d'isolation thermiques sont agencés de manière à permettre un accès aux logements destinés à recevoir les éléments de stabilisation thermique sans ouverture de l'espace intérieur de conditionnement des produits. Une telle structure est particulièrement avantageuse puisque cela participe au maintien d'une température stabilisée homogène à l'intérieur du volume de conditionnement des produits. En effet, cela permet de remplacer n'importe lequel des stabilisateurs thermiques tout en maintenant les produits stockés dans le dispositif de conditionnement isolés du milieu extérieur. Les produits stockés ne subissent ainsi pas d'écart ou de variation de température importants qui pourraient leur être nuisibles.The thermal insulation panels are arranged to allow access to the housing for receiving the thermal stabilization elements without opening the interior of the product packaging space. Such a structure is particularly advantageous since it contributes to the maintenance of a homogeneous stabilized temperature within the packaging volume of the products. Indeed, this makes it possible to replace any of the thermal stabilizers while maintaining the products stored in the conditioning device isolated from the external environment. The stored products thus do not undergo any significant variation or temperature variation that could be harmful to them.

D'autres caractéristiques et avantages de l'invention ressortiront encore de la description qui suit, laquelle est purement illustrative et non limitative et doit être lue en regard des dessins annexés, sur lesquels :

Comme on le voit illustré sur les figures, le dispositif de conditionnement selon l'invention comprend une boite 1 de forme parallélépipédique qui présente une face permettant le chargement des produits. Cette face comprend un élément d'obturation amovible par rapport aux autres faces constituant la boite, de manière à permettre un accès vers l'intérieur de la boite c'est-à-dire dans l'espace de conditionnement des produits à maintenir dans des conditions de température stabilisées.As can be seen in the figures, the packaging device according to the invention comprises a
La boite est constituée par des panneaux d'isolation thermique qui sont agencés les uns par rapport aux autres pour former ladite boite parallélépipédique. A l'intérieur de la boite est également prévu un certain nombre de logements agencés pour recevoir des stabilisateurs thermiques qui ont pour objet de maintenir le volume de conditionnement intérieur dans une plage de température déterminée, notamment en fonction des conditions extérieures de stockage et/ou de transport.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.
La configuration proposée décrite en détail ci-dessous pour la boite isotherme 1 permet un accès aux logements destiné à recevoir les stabilisateurs thermiques sans ouverture de l'espace intérieur de conditionnement des produits. Ainsi, cela permet de limiter toutes perturbations thermiques au niveau des produits stockés à l'intérieur de la boite, notamment en cas de remplacement des stabilisateurs thermiques pendant le transport de la boite isotherme 1.The proposed configuration described in detail below for the
Pour garantir une stabilité thermique optimale, il est prévu dans la boite isotherme, selon l'invention, des logements destinés à recevoir des stabilisateurs thermiques au niveau de la face opposée à la face de chargement, afin d'avoir un maximum des faces de la boite comprenant des éléments de stabilisation thermique.In order to guarantee optimum thermal stability, housings intended to receive thermal stabilizers at the level of the face opposite to the loading face are provided in the isothermal box according to the invention, so as to have a maximum of the faces of the box comprising elements of thermal stabilization.
Dans le cas des boites isothermes de grande capacité, c'est-à-dire ayant un volume de stockage de plusieurs centaines de litres, la face de chargement des produits est de préférence la face avant de la boite de sorte que les produits peuvent être chargés horizontalement, au niveau du sol, plutôt que par le dessus. Dans ce cas, on prévoit des logements pour stabilisateurs thermiques sur la face arrière de la boite qui est bien la face opposée à la face de chargement.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.
Selon l'invention, il est prévu une trappe escamotable sur la partie arrière de la boite qui permet de positionner des stabilisateurs thermiques dans les logements prévus sur la face arrière de la boite sans accéder au volume intérieur de conditionnement des produits, en particulier sans avoir à utiliser la voie d'accès principale de la boite par la face avant, qui nécessiterait de traverser l'espace intérieur de conditionnement. Plus précisément, la trappe escamotable correspond à une ouverture ménagée dans la boite, par exemple au niveau de l'arrête latérale entre la face arrière et une des faces latérales de la boite. Une telle ouverture, de préférence de forme longitudinale, permet donc d'insérer des stabilisateurs thermiques à l'intérieur de la boite dans les logements prévus à cet effet sur la face arrière. En outre est prévu un élément d'obturation destiné à venir fermer l'ouverture latérale de positionnement des stabilisateurs thermiques arrière.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.
Une telle configuration permet donc de prévoir des logements sur chacune des faces périphériques de la boite isotherme 1, ces logements étant configurés pour pouvoir recevoir des stabilisateurs thermiques destinés à être chargés depuis la face avant de la boite. La face avant comprend quant à elle également des logements destinés à recevoir des stabilisateurs thermiques de sorte que la boite isotherme 1 selon l'invention peut comprendre des stabilisateurs thermiques sur chacune des faces qui la composent, garantissant ainsi une stabilité thermique accrue, ainsi qu'une homogénéité dans la régulation thermique au niveau des produits stockés dans l'espace intérieur de conditionnement.Such a configuration therefore allows to provide housing on each of the peripheral faces of the
Cette configuration est particulièrement avantageuse puisqu'elle permet un chargement des stabilisateurs thermiques sans avoir à accéder à l'espace intérieur de conditionnement. En effet, les stabilisateurs des faces périphériques peuvent être positionnés depuis la face avant. Les stabilisateurs de la face avant sont positionnés au moment de refermer la voie d'accès principale. Et enfin, les stabilisateurs thermiques arrière sont positionnés au niveau de la face arrière en utilisant la trappe escamotable ménagée à l'arrière de la boite.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.
Nous allons maintenant décrire un mode de réalisation particulier de l'invention en référence aux
En référence à la
Dans le mode de réalisation présenté sur les
Les panneaux d'isolation thermique utilisés pour former chacune des faces composant la boite isotherme 1 peuvent prendre diverses formes. Il peut par exemple être prévu des panneaux d'isolation thermique à fourreaux dont la structure permet à la fois d'assurer l'isolation thermique nécessaire, la régulation thermique par la réception de stabilisateurs thermiques 80, et conférant également à la boite isotherme une résistance mécanique accrue.The thermal insulation panels used to form each of the faces composing the
En référence à la
Chacun des panneaux d'isolation thermique à fourreaux comprend une plaque externe (21, 41, 51, 61) destinée à former la surface extérieure de la face correspondante, et formant donc l'enveloppe externe de la boite isotherme 1. A cet égard, elle est revêtue d'un matériau de protection, de type kraft ou carton par exemple. Cette plaque externe peut en outre avoir une fonction d'isolation. La plaque externe peut donc être formée dans un matériau isolant revêtu d'un matériau protecteur. Le matériau isolant peut par exemple être du polyuréthane, du polystyrène, du polystyrène expansé extrudé (XPS pour « extruded polystyrene »), du polyéthylène, ou être formé de panneaux sous vides (VIP selon l'acronyme anglais de « Vacuum Insulated Panels »).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
Chaque panneau d'isolation thermique à fourreaux comprend par ailleurs au moins une plaque interne (22, 42, 52, 62) destinée à former la surface intérieure de chacune des faces correspondantes, et donc définissant l'espace intérieur de conditionnement des produits de la boite isotherme 1. De préférence, ces plaques internes (22, 42, 52, 62) sont formées dans des matériaux isolants choisis en fonction des conditions de stockage de produits et des gammes de maintien en température recherchées. De telles plaques internes d'isolation (22, 42, 52, 62) peuvent par exemple être formées dans des matériaux à base de polystyrène, de polyuréthane, de polyéthylène, etc. Les plaques internes pourront par exemple être formées à base de polystyrène expansé extrudé (XPS pour « extruded polystyrene »), ou être formées de panneaux sous vides (VIP selon l'acronyme anglais de « Vacuum Insulated Panels »).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").
Enfin, chacun des panneaux d'isolation thermique à fourreaux comprend des entretoises (23, 43, 53, 63) agencées entre la plaque externe (21, 41, 51, 61) et la plaque interne (22, 42, 52, 62) du panneau correspondant et étant agencées les unes par rapport aux autres de manière à former des fourreaux pour le logement des stabilisateurs thermiques 80. Ces entretoises (23, 43, 53, 63) ont de préférence une forme longitudinale et sont réparties sur les plaques externes et internes de manière à assurer une certaine rigidité aux panneaux d'isolation thermique à fourreaux considérés. Par ailleurs, ces entretoises (23, 43, 53, 63) permettent également d'assurer une résistance mécanique accrue de l'ensemble de boite isotherme 1 lorsque les panneaux d'isolation thermiques à fourreaux sont assemblés les uns avec les autres afin de former les différentes faces de la boite isotherme 1. Cette configuration des panneaux d'isolation thermique à fourreaux avec l'utilisation d'entretoises transversales est également particulièrement avantageuse pour la réception des stabilisateurs thermiques 80 qui peuvent avoir un poids relativement élevé. En effet, les fourreaux créés grâce aux entretoises forment des glissières à l'intérieur desquelles les stabilisateurs thermiques 80 peuvent être insérés et translatés.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
De préférence, les entretoises sont également formées dans un matériau isolant, par exemple à base de polystyrène, de polyuréthane, de polyéthylène, etc. Selon un mode de réalisation préféré, les panneaux d'isolation thermique à fourreaux ont une plaque externe en polyuréthane revêtue de kraft, des entretoises et une plaque externe en polystyrène expansé extrudé XPS.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.
Dans le mode de réalisation présenté à la
Le panneau avant 10 de la boite isotherme 1 pourrait également se présenter sous la forme d'un panneau d'isolation thermique à fourreaux qui serait positionné en appui sur les arrêtes des différentes faces périphériques (30, 40, 50, 60) de la boite isotherme 1. Toutefois, selon le mode de réalisation préféré, illustré aux figures, la face avant 10 de la boite isotherme 1 comprend deux plaques distinctes 11 et 12 permettant d'assurer une obturation en deux temps de l'accès principal de la boite isotherme 1.The
En effet, comme cela est illustré en
Par ailleurs, la face avant 10 de la boite isotherme 1 comprend une plaque externe 11 destinée à être positionnée sur la plaque interne 12 pour la recouvrir et pour recouvrir également les accès aux différents logements formés par les fourreaux des plaques d'isolation thermique à fourreaux constituant les faces périphériques de la boite isotherme 1. A cet égard, la plaque externe 11 a des dimensions sensiblement supérieures à la plaque intermédiaire 12 de la face avant 10.Furthermore, the
Comme il ressort de la description qui précède, chacune des faces de la boite isotherme 1 est fabriqué à partir de panneaux d'isolation thermique plans et indépendants les uns des autres ce qui facilite grandement à la fois la manutention et le stockage de la boite isotherme 1. En effet, lorsque la boite isotherme 1 n'est pas utilisée, c'est-à-dire lorsqu'il n'est pas nécessaire de transporter ou stocker des produits thermosensibles, alors celle-ci peut être stockée ou transportée de façon complètement démontée, les plaques d'isolation thermique étant à cet effet simplement empilées les unes sur les autres. Un tel agencement démonté permet un gain de volume particulièrement avantageux pour le stockage mais également pour le transport des éléments constituant la boite isotherme 1.As is apparent from the foregoing description, each of the faces of the
Le fait que les différentes faces de la boite isotherme 1 soient constituées de panneaux plans permet également de faciliter son montage et démontage. En effet, comme cela est illustré à la
Ainsi, on peut par exemple positionner dans un premier temps la plaque 31 formant la face inférieure, c'est-à-dire la base de la boite isotherme 1. On vient ensuite positionner autour de cette plaque inférieure 31 les panneaux d'isolation thermique à fourreaux définissant les faces latérales ainsi que le panneau d'isolation thermique à fourreaux définissant la face arrière 20. Ces différents panneaux coopèrent les uns avec les autres et avec le panneau inférieur 31 par tous moyens de fixation appropriés, par exemple par des coopérations de forme entre les différents panneaux, ou simplement par l'utilisation de moyens de fixation adaptés (colle, visserie, etc.). Une fois que les faces latérales 50 et 60 et la face arrière 20 sont positionnées autour de la face inférieure 30, la face supérieure est positionnée entre les faces latérales 50 et 60 et la face arrière 20 définissant ainsi une boite parallélépipédique avec une seule face ouverte. Le panneau d'isolation thermique à fourreaux de la face supérieure 40, vient également coopérer avec les panneaux qui lui sont adjacents, des moyens de fixation pouvant par ailleurs être prévus pour maintenir ces panneaux. Un ensemble de sangles 90 peut en outre venir en complément ou remplacement de tout système de fixation entre les panneaux. Une fois cet assemblage effectué, on obtient une boite isotherme 1 telle que représentée sur la
Comme il ressort de la
Il est en outre prévu des éléments d'obturation 70 de ces ouvertures latérales, de manière à constituer des trappes escamotables d'accès aux fourreaux du panneau d'isolation thermique à fourreaux de la face arrière 20. De tels éléments d'obturation 70 peuvent par exemple prendre la forme de barres longitudinales (71 ; 72) ayant une forme correspondant à l'ouverture ménagée le long de l'arrête entre la face arrière 20 et l'une des faces latérales 50 et 60. De manière encore préférée, les barres longitudinales (71 ; 72) sont prévues pour être positionnées de manière affleurante par rapport aux faces externes des panneaux externes (51 ; 61) des faces latérales (50 ; 60).In addition, shut-off
Ces ouvertures latérales positionnées au niveau de la face arrière 20 de la boite isotherme 1, permettent un accès aux logements des stabilisateurs thermiques destinés à être positionnés sur la face arrière. S'il est impératif d'avoir au moins une trappe escamotable au niveau de la face arrière 20 pour le chargement et déchargement des stabilisateurs thermiques 80 sur cette face arrière 20 sans avoir à accéder à l'espace intérieur de conditionnement des produits, on peut également prévoir d'autres trappes escamotables dans la boite isotherme 1 pour faciliter également la mise en place et le retrait des stabilisateurs thermiques 80 positionnés sur les autres faces constituant la boite isotherme 1.These lateral openings positioned at the
Une fois que la boite isotherme 1 a été montée, c'est-à-dire lorsque les différentes faces latérales et la face arrière sont solidaires les unes des autres, alors la boite isotherme 1 est prête pour recevoir les produits thermosensibles destinés à être maintenus dans une gamme de température déterminée.Once the
L'accès aux différents logements destinés à recevoir les stabilisateurs thermiques 80 est très aisé, puisque les logements de la face arrière 20 sont accessibles par l'intermédiaire de l'une des deux trappes escamotables latérales, après avoir retiré l'une des barres longitudinales (71, 72). De la même manière, il est simple de positionner les stabilisateurs thermiques 80 dans les fourreaux ménagés sur les faces périphériques de la boite isotherme 1, l'accès à ces logements étant effectué depuis la face avant 10 de la boite isotherme 1.Access to the various housings intended to receive the
Comme on le voit sur la
Une fois que les stabilisateurs thermiques 80 des faces périphériques et de la face arrière sont positionnés dans la boite isotherme 1, les produits à conditionner peuvent être mis en place dans l'espace intérieur de conditionnement et la face avant 10 est ensuite positionnée pour fermer cet espace intérieur de conditionnement. Plus précisément, le panneau intermédiaire 12 de la face avant est positionné de manière à obturer l'accès principal de l'espace intérieur de conditionnement. Comme indiqué plus haut, la plaque intermédiaire 12 comprend des logements 13 permettant de positionner des stabilisateurs thermiques 80 de sorte que la face avant comprenne également des moyens de stabilisation thermique. Une fois que ces stabilisateurs thermiques 80 sont positionnés dans le logement 13 prévu sur la face avant 10, le panneau externe 11 de la face avant est positionné pour obturer totalement la boite isotherme 1.Once the
Une fois que tous les panneaux d'isolation thermique sont positionnés afin de former la boite isotherme 1, ceux-ci peuvent être solidarisés par tout moyen approprié. On peut par exemple utiliser des sangles 90 comme cela est illustré sur la
Un des avantages présenté par la boite isotherme 1 décrite ici est la possibilité de pouvoir remplacer les stabilisateurs thermiques 80 positionnés dans les différents logements prévus à l'intérieur de la boite isotherme 1 sans ouvrir l'espace intérieur de conditionnement recevant les produits thermosensibles. En effet, s'il s'avérait nécessaire de remplacer les différents stabilisateurs thermiques 80 utilisés dans la boite isotherme 1, il suffit de retirer la plaque externe 11 de la face avant pour pouvoir accéder aux logements à la fois de la face avant et des faces périphériques de la boite isotherme. La présence de la plaque intermédiaire 12 au niveau de l'accès principal de l'espace intérieur de conditionnement permet de maintenir cet espace intérieur de conditionnement fermé. De la même manière, il est possible de changer les stabilisateurs thermiques 80 prévus au niveau de la face arrière 20 grâce aux trappes escamotables 70 ménagées au niveau de la phase arrière 20 de la boite isotherme 1.One of the advantages presented by the
Cette configuration est particulièrement avantageuse puisqu'elle permet de garantir que le produit reste isolé thermiquement, grâce aux différents panneaux isolants internes (12, 22, 31, 42, 52, 62) qui définissent l'espace intérieur de conditionnement.This configuration is particularly advantageous since it makes it possible 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 conditioning space.
La structure et le mode d'assemblage proposé pour la boite isotherme 1 permet également d'optimiser le temps de préparation tout en sécurisant et garantissant un meilleur respect de la chaine du froid. En effet, ce mode d'assemblage permet si nécessaire de dissocier le temps de l'opération montage de la boite isotherme 1 du temps de l'opération de préparation pour l'expédition. On peut ainsi préparer la structure de la boite isotherme 1 la veille, insérer les produits thermosensibles et stocker la boite isotherme dans une chambre de froid pour maintenir la température, puis insérer les stabilisateurs thermiques 80 au dernier moment juste avant l'expédition afin d'obtenir une autonomie la plus longue possible. Le produit est protégé par les plaques d'isolation thermique internes le temps de l'insertion des stabilisateurs thermiques 80 dans leurs logements respectifs.The structure and the method of assembly proposed for the
Les logements étant de préférence formés par des fourreaux agencés sur les différents panneaux d'isolation thermique constituant les faces de la boite isotherme 1, il est préférable d'utiliser des stabilisateurs thermiques 80 ayant une forme longitudinale de manière à faciliter leurs glissements dans ces logements. Par ailleurs, si la boite isotherme 1 est de très grande dimension, il est possible d'utiliser des stabilisateurs thermiques 80 couplés entre eux par tous moyens de liaison permettant ainsi de les rendre solidaires les uns des autres, notamment pour leur retrait desdits logements depuis une seule extrémité du fourreau.The housings being preferably formed by sheaths arranged on the various thermal insulation panels constituting the faces of the
Les stabilisateurs thermiques 80 sont généralement des briquettes rigides ou semi-rigides formés d'une enveloppe plastique (par exemple du polyéthylène haute densité - PEHD) contenant un agent eutectique permettant d'assurer la fonction de stabilisation thermique recherchée.The
Le lecteur aura compris que de nombreuses modifications peuvent être apportées sans sortir matériellement des nouveaux enseignements et des avantages décrits ici.
