Description

Emballage isothermique Isothermal packaging
La présente invention concerne un emballage isother¬ mique permettant de conserver au frais des objets durant leur transport. L'emballage est plus particulièrement des¬ tiné à recevoir des denrées alimentaires, des produits médico-pharmaceutiques ou cosmétiques ou toutes marchan¬ dises susceptibles de subir des modifications au contact de la chaleur.The present invention relates to isothermal packaging for keeping objects cool during transport. The packaging is more particularly intended to receive foodstuffs, medico-pharmaceutical or cosmetic products or any goods which are liable to undergo modifications in contact with heat.
Généralement pour transporter ce type de denrées, on utilise des dispositifs connus sous le nom de "cool-box" qui se présentent sous la forme d'une boîte dans laquelle sont disposés un ou plusieurs éléments refroidissants pré¬ alablement congelés.Generally for transporting this type of food, devices known as “cool-boxes” are used which are in the form of a box in which one or more pre-frozen cooling elements are placed.
On connaît également des sacs isothermiques dont les parois comportent des logements destinés à recevoir des refroidisseurs. Ces derniers n'assurent pas une tempéra¬ ture homogène des aliments à conserver; il est en effet assez difficile de positionner les denrées dans un sac ou dans une boîte afin qu'elles soient directement à proximi¬ té des refroidisseurs.-Isothermal bags are also known, the walls of which include housings intended to receive coolers. The latter do not ensure a uniform temperature of the food to be preserved; it is indeed quite difficult to position the foodstuffs in a bag or in a box so that they are directly close to the coolers.
Le but de la présente invention est de remédier aux inconvénients mentionnés ci-dessus en proposant un embal¬ lage peu encombrant qui offre une excellente conservation des aliments ou autres denrées en présence d'une tempéra¬ ture ambiante élevée et ce pendant une durée adaptée à un usage domestique. Grâce à cet emballage isothermique, on assure une température homogène des denrées à conserver durant leur transport.The object of the present invention is to remedy the drawbacks mentioned above by proposing a space-saving packaging which offers excellent preservation of food or other foodstuffs in the presence of a high ambient temperature and for a period adapted to domestic use. Thanks to this isothermal packaging, a uniform temperature is ensured for the foodstuffs to be stored during their transport.
D'autre part cet emballage doit être facile à fabri¬ quer, d'un coût de revient modeste et pratique à l'utili¬ sation. L'espace publicitaire occupe toute la surface si nécessaire. L'emballage objet de la présente invention se distingue par les caractéristiques énumérées à la revendi¬ cation 1.On the other hand, this packaging must be easy to manufacture, with a modest cost price and practical to use. The advertising space occupies the entire surface if necessary. The packaging which is the subject of the present invention is distinguished by the characteristics listed in claim 1.
D'autres avantages ressortent des caractéristiques exprimées dans les revendications dépendantes et de la description exposant ci-dessous l'invention plus en détail à l'aide de dessins qui représentent schématiquement et à titre d'exemple trois formes d'exécution de l'emballage.Other advantages emerge from the characteristics expressed in the dependent claims and from the description setting out the invention below in more detail with the aid of drawings which schematically represent by way of example three embodiments of the packaging .
La figure 1 est une vue de dessus d'une première forme d'exécution de l'emballage en position ouverte, avant utilisation.Figure 1 is a top view of a first embodiment of the packaging in the open position, before use.
La figure 2 est une vue en perspective de l'emballage illustré à la figure 1.FIG. 2 is a perspective view of the packaging illustrated in FIG. 1.
La figure 3 est une vue en perspective de l'emballage illustré à la figure 1 en position repliée.Figure 3 is a perspective view of the packaging illustrated in Figure 1 in the folded position.
La figure 4 est une vue de dessus d'une deuxième forme d'exécution de l'emballage.Figure 4 is a top view of a second embodiment of the package.
Les figures 5 et 6 sont des vues en perspective de l'emballage de la figure 4 illustrant l'emballage ouvert pour permettre l'introduction respectivement des denrées à conserver et des refroidisseurs.Figures 5 and 6 are perspective views of the packaging of Figure 4 illustrating the packaging opened to allow the introduction respectively of foodstuffs and coolers.
La figure 7 est une vue en coupe transversale de l'emballage de la figure 4.Figure 7 is a cross-sectional view of the packaging of Figure 4.
La figure 8 est une vue en coupe d'une troisième forme d'exécution de l'emballage isothermique. En référence à la figure 1, l'emballage est constitué d'une bande obtenue par la superposition de deux feuilles 1,1' en matière isolante. Les feuilles isolantes 1,1 ' seront de préférence constituées d'une structure à deux couches. La feuille inférieure 1 ' est composée d'une couche en mousse de polyethylene expansé recouverte d'un film de PET. La feuille supérieure 1 se compose d'une couche en polyethylene présentant une structure alvéolaire ou une structure à bulles recouverte d'un film blanc de polyethylene. Une couche PET intérieure ou extérieure peut être recouverte d'un film aluminisé pour obtenir une meil¬ leure réfléxivité des rayons du soleil. Il est bien évident que d'autres matériaux présentant de bonnes quali¬ tés isothermiques peuvent être utilisés pour réaliser ces feuilles isolantes 1,1'.Figure 8 is a sectional view of a third embodiment of the isothermal packaging. Referring to Figure 1, the packaging consists of a strip obtained by the superposition of two sheets 1,1 'of insulating material. The insulating sheets 1,1 'will preferably consist of a two-layer structure. The lower sheet 1 'is composed of a layer of expanded polyethylene foam covered with a PET film. The top sheet 1 consists of a polyethylene layer having a honeycomb structure or a bubble structure covered with a white polyethylene film. An inner or outer PET layer can be covered with an aluminized film to obtain better reflectivity of the sun's rays. It is obvious that other materials having good isothermal qualities can be used to make these insulating sheets 1,1 '.
La bande formant l'emballage est obtenue par superpo¬ sition des deux feuilles 1,1', leur face en polyethylene expansé étant en contact. Les feuilles 1,1' sont ensuite maintenues ensemble le long de leurs bords, par exemple par soudage à chaud. Des lignes de soudure à chaud déli¬ mitent des poches 2, 2' qui présentent une ouverture 3,3' sur un de leurs côtés. Comme l'illustre la figure 2, ces poches 2,2' sont destinées à recevoir des refroidisseurs. Les refroidisseurs sont constitués d'une enveloppe exté¬ rieure en plastique contenant un liquide tel que du glycol par exemple, et dont la quantité et la grandeur varient selon la grandeur de l'emballage. Il est ainsi possible de congeler ces refroidisseurs et de les introduire une fois congelés dans les poches 2,2' par les ouvertures 3,3'. Des moyens de fermeture 4,4' des ouvertures 3,3' sont prévus afin d'éviter que les refroidisseurs ne s'échappent de leurs logements. Ces moyens de fermeture 4,4' peuvent être réalisés par tous moyens connus en particulier on peut prévoir des boutons pression, une fermeture de type "Vel- cro" ou encore une fermeture à glissière.The strip forming the packaging is obtained by superposition of the two sheets 1,1 ′, their face in expanded polyethylene being in contact. The sheets 1,1 'are then held together along their edges, for example by heat welding. Heat seal lines delimit pockets 2, 2 'which have an opening 3.3' on one of their sides. As illustrated in Figure 2, these pockets 2,2 'are intended to receive coolers. The coolers consist of a plastic outer envelope containing a liquid such as glycol for example, and the quantity and size of which vary according to the size of the packaging. It is thus possible to freeze these coolers and introduce them once frozen in the bags 2.2 ′ through the openings 3.3 ′. Closing means 4,4 'of openings 3,3' are provided to prevent the coolers from escaping from their housings. These closing means 4,4 ′ can be produced by any known means, in particular press buttons, a "Velcro" type closure or a zipper can be provided.
Dans une variante, les refroidisseurs ne sont pas amovibles mais sont pris dans l'épaisseur de la bande, entre les deux feuilles 1,1' . Dans ce cas c'est tout le dispositif que l'on introduira dans un congélateur en vue de sa réfrigération. Pour éviter la formation de moisis¬ sures, on imbibera l'intérieur de la poche contenant le refroidisseur d'un agent conservateur ad hoc, tel que l'é- thyleap à base d'alcool.In a variant, the coolers are not removable but are taken in the thickness of the strip, between the two sheets 1,1 '. In this case it is the whole device that will be introduced into a freezer for refrigeration. To avoid the formation of mold, the interior of the bag containing the cooler will be soaked with an ad hoc preservative, such as alcohol-based ethyleap.
Des découpes 5,5 ',5" sont situées aux extrémités de la bande formant l'emballage. Ces découpes 5,5',5" forment une poignée lorsque la bande est repliée sur elle-même le long d'une ligne médiane 7.5.5 ', 5 "cutouts are located at the ends of the strip forming the package. These 5.5', 5" cutouts form a handle when the strip is folded back on itself along a center line 7 .
Cette poignée a pour fonction de faciliter le trans¬ port de l'emballage lorsque ce dernier contient un aliment. Pour utiliser l'emballage selon la présente in¬ vention, on place l'emballage de préférence sur une sur¬ face plane, puis on dispose l'objet à emballer sur l'une des poches 2 contenant le refroidisseur, de telle sorte que la surface inférieure de l'objet soit en contact avec le refroidisseur contenu dans la poche 2. On replie en¬ suite l'emballage le long de la ligne 7 de telle sorte que la poche 2' contenant le refroidisseur soit en contact avec la surface supérieure de l'objet comme l'illustre la figure 3. Des moyens de fermeture 6 sont agencés de façon à permettre le maintien de l'emballage dans cette position repliée. Ces moyens de fermeture sont constitués par exemple par des boutons pression en plastique ou des lan¬ guettes auto-adhésives à usage multiple. Dans le cas de petits emballages, un simple recouvrement des extrémités des feuilles 1,1' est suffisant, sans qu'il soit néces¬ saire de prévoir les découpes 5,5',5" servant à constituer la poignée.The purpose of this handle is to facilitate the transport of the packaging when the latter contains a food. To use the packaging according to the present invention, the packaging is preferably placed on a flat surface, then the object to be packaged is placed on one of the pockets 2 containing the cooler, so that the lower surface of the object is in contact with the cooler contained in the bag 2. The packaging is then folded along the line 7 so that the bag 2 'containing the cooler is in contact with the upper surface of the object as illustrated in Figure 3. Closing means 6 are arranged so as to allow the packaging to be held in this folded position. These closing means are constituted for example by plastic snaps or self-adhesive lan¬ guettes for multiple use. In the case of small packages, a simple covering of the ends of the sheets 1,1 ′ is sufficient, without it being necessary to provide the cutouts 5,5 ′, 5 "used to constitute the handle.
Il va de soi que d'autres moyens de fermeture peuvent être envisagés pour réaliser le maintien de l'emballage dans la position illustrée à la figure 3.It goes without saying that other closing means can be envisaged in order to maintain the packaging in the position illustrated in FIG. 3.
La bande constituée des feuilles isolantes 1,1' peut comporter une pluralité de poches 2 destinées à recevoir des refroidisseurs, de telle sorte que l'on puisse dispo¬ ser plusieurs aliments par pliages successifs de la bande sur elle-même et empilage des refroidisseurs les uns sur les autres, chaque aliment étant alors pris en sandwich entre deux refroidisseurs.The strip consisting of the insulating sheets 1,1 ′ may comprise a plurality of pockets 2 intended to receive coolers, so that several foods can be provided by successive folding of the strip on itself and stacking of the coolers on top of each other, each food then being sandwiched between two coolers.
Ce dispositif présente encore l'avantage d'être ré¬ utilisable, lui conférant de ce fait des qualités écolo¬ giques.This device also has the advantage of being reusable, thereby giving it ecological qualities.
Des essais effectués en laboratoire ont montré qu'un tel emballage permet de maintenir les aliments à une tem¬ pérature inférieure à 23° pendant les durées mentionnées ci-dessous pour diverses températures ambiantes. A température ambiante de 23°Tests carried out in the laboratory have shown that such packaging makes it possible to maintain food at a temperature below 23 ° for the periods mentioned below for various ambient temperatures. At room temperature of 23 °
- 1 refroidisseur de 2 dl à -18° = 10 heures- 1 cooler of 2 dl at -18 ° = 10 hours
- 1 refroidisseur de 2 dl à - 7° = 3 heures A température ambiante de 30°- 1 cooler of 2 dl at - 7 ° = 3 hours At room temperature of 30 °
- 2 refroidisseurs de 2 dl à -18° = 6 heures 30 A température ambiante de 40°- 2 coolers of 2 dl at -18 ° = 6 hours 30 At 40 ° ambient temperature
- 2 refroidisseurs de 2 dl à -18° = 5 heures 30- 2 coolers of 2 dl at -18 ° = 5 hours 30
La deuxième forme d'éxecution de l'emballage isother¬ mique illustré à la figure 4 se présente sous la forme d'une pochette rectangulaire 8; la pochette se compose de deux ou plusieurs sachets de même type de matériel s'im¬ briquant les uns dans les autres dans un sens ou dans l'autre pour éviter des échanges de température. Cette po¬ chette 8, dont les dimensions peuvent varier en fonction des denrées à conserver, comporte deux ouvertures 9,10 s'étendant sur toute la largeur des petits côtés du rec¬ tangle. Des moyens de fermeture 11, 11', 12,12' sont prévus à proximité de chacune des ouvertures. Ces moyens de fer¬ meture sont constitués par exemple de glissières en plas¬ tique collées ou soudées à chaud sur les bord intérieurs de la pochette 8. Il est ainsi possible de fermer la po¬ chette par simple pression en appliquant le bord supérieur sur le bord inférieur.The second form of execution of the insulated packaging illustrated in FIG. 4 is in the form of a rectangular pocket 8; the pouch is composed of two or more sachets of the same type of material, which are imbricated in one direction in one direction or the other to avoid temperature exchanges. This po¬ chette 8, the dimensions of which may vary depending on the foodstuffs to be stored, has two openings 9,10 extending over the entire width of the short sides of the rec¬ tangle. Closing means 11, 11 ', 12, 12' are provided near each of the openings. These closing means consist for example of plastic slides glued or hot welded to the inner edges of the pocket 8. It is thus possible to close the pocket by simple pressure by applying the upper edge to the bottom edge.
A l'intérieur de la pochette 8 se trouve une enve¬ loppe interne 13 que l'on distingue en pointillés sur la figure 4. Cette enveloppe interne 13 destinée à recevoir les aliments ou d'autres produits à conserver est fermée sur trois de ces côtés et présente une ouverture qui coïn¬ cide avec l'une des ouvertures de la pochette 8. L'enve- loppe 13 est maintenue par soudage à chaud à l'intérieur de la pochette 8 au niveau de son ouverture. La soudure relie la face interne de la pochette 8 à la face externe de l'enveloppe 13 sur environ 1 centimètre, de telle sorte que lorsqu'on ouvre la pochette, comme l'illustre la figure 5, on accède directement à l'intérieur de l'enve¬ loppe. A l'autre extrémité de la pochette (figure 6), l'enveloppe 13 est libre et permet l'introduction de re¬ froidisseurs 14,14' entre la face interne de la pochette 8 et l'enveloppe 13 comme le montre les flèches F,F1.Inside the pocket 8 is an internal envelope 13 which can be seen in dotted lines in FIG. 4. This internal envelope 13 intended to receive food or other products to be kept is closed on three of these sides and has an opening which coincides with one of the openings in the pocket 8. The envelope loppe 13 is maintained by hot welding inside the pocket 8 at its opening. The weld connects the internal face of the pocket 8 to the external face of the envelope 13 over approximately 1 centimeter, so that when the pocket is opened, as illustrated in FIG. 5, one reaches directly inside of the envelope. At the other end of the pouch (FIG. 6), the casing 13 is free and allows the introduction of coolers 14, 14 'between the internal face of the pouch 8 and the casing 13 as shown by the arrows F, F 1 .
L'utilisation de l'emballage est extrêmement pratique puisque' il suffit d'ouvrir la pochette à l'extrémité qui coïncide avec l'ouverture de l'enveloppe 13 et d'y intro¬ duire les denrées à conserver, puis on introduit par l'autre extrémité deux refroidisseurs de part et d'autre de l'enveloppe 13. L'enveloppe 13 isole ainsi les denrées à conserver des refroidisseurs et se trouve prise en sand¬ wich entre deux refroidisseurs 14, comme illustré en coupe à la figure 7, assurant de ce fait une température homo¬ gène à l'intérieur de l'enveloppe.The use of the packaging is extremely practical since 'it suffices to open the pouch at the end which coincides with the opening of the envelope 13 and to introduce therein the foodstuffs to be preserved, then introduced by the other end two coolers on either side of the casing 13. The casing 13 thus isolates the foodstuffs to be kept coolers and is taken in sand¬ wich between two coolers 14, as illustrated in section in the figure 7, thereby ensuring a uniform temperature inside the envelope.
Dans une variante, la pochette 8 peut être munie d'une poignée pour faciliter son transport.In a variant, the pocket 8 can be provided with a handle to facilitate its transport.
Les matériaux utilisés pour la réalisation de la po¬ chette 8 et de l'enveloppe 13 sont identiques à ceux dé¬ crits dans la première forme d'exécution, à savoir une couche en mousse de polyethylene expansé recouverte d'un film de PET. D'autre matériaux présentant de bonnes carac¬ téristiques isothermiques peuvent également être utilisés.The materials used for the production of the pocket 8 and of the casing 13 are identical to those described in the first embodiment, namely a layer of expanded polyethylene foam covered with a film of PET. Other materials with good isothermal characteristics can also be used.
La figure 8 illustre une troisième forme d'exécution de l'emballage selon la présente invention plus particu- lièrement destiné à recevoir des denrées volumineuses. L'emballage se compose d'un boîtier externe 15 en polysty¬ rène expansé ou en polypropylene à l'intérieur duquel se trouve un compartiment interne amovible ou fixe 16, s'im¬ briquant l'un dans l'autre, dans un sens ou dans l'autre, afin d'éviter tout échange de température. Le compartiment interne 16 est destiné à recevoir les denrées à conserver. Des refroidisseurs 14,14' sont introduits en dessous et au dessus du compartiment 16. La fermeture de l'emballage s'effectue à l'aide d'un couvercle (non représenté) ou de tout autre moyen connu.FIG. 8 illustrates a third embodiment of the packaging according to the present invention more particularly intended for the reception of bulky food. The packaging consists of an external casing 15 made of expanded polystyrene or polypropylene, inside of which is a removable or fixed internal compartment 16, which is built into one another in one direction. or in the other, in order to avoid any temperature exchange. The internal compartment 16 is intended to receive the foodstuffs to be stored. Coolers 14, 14 ′ are introduced below and above the compartment 16. The packaging is closed using a cover (not shown) or any other known means.
Ces emballages sont d'un coût modeste à fabriquer, d'une utilisation extrêmement simple et aisée et pré¬ sentent l'avantage d'être réutilisables à volonté. Ils sont donc parfaitement adaptés à un usage domestique. These packages are of low cost to manufacture, extremely simple and easy to use and present the advantage of being reusable at will.
