Abstract
Description
La présente invention a pour objet un emballage isothermique qui permet au moins de doubler, toutes conditions et proportions gardées, la durée pendant laquelle le produit est maintenu à une température acceptable, c'est-à-dire se situant au-dessus ou au-dessous selon le cas de la température critique. The subject of the present invention is an isothermal packaging which makes it possible at least to double, all conditions and proportions kept, the time during which the product is kept at an acceptable temperature, that is to say being above or above below depending on the critical temperature.
Cet emballage, qui est constitué par une enveloppe présentant une ouverture pour l'introduction et le retrait du produit, est caractérisé par le fait que les parois de l'enveloppe sont formées chacune de plusieurs feuilles délimitant entre elles au moins un espace fermé rempli d'un fluide. This packaging, which consists of an envelope having an opening for the introduction and the withdrawal of the product, is characterized in that the walls of the envelope are each formed of several sheets delimiting between them at least one closed space filled with 'a fluid.
Le dessin ci-annexé représente schématiquement et à titre d'exemple non limitatif une forme d'exécution de l'objet de l'invention et illustre un procédé de fabrication de cette forme d'exécution de l'emballage selon l'invention. The attached drawing shows schematically and by way of nonlimiting example an embodiment of the object of the invention and illustrates a method of manufacturing this embodiment of the packaging according to the invention.
La fig. 1 est une vue en plan de l'emballage vide; Fig. 1 is a plan view of the empty package;
la fig. 2 en est une section par la ligne II-II de la fig. 1 ; fig. 2 is a section through the line II-II of FIG. 1;
la fig. 3 est une section, analogue à la fig. 2, de l'emballage contenant un produit. fig. 3 is a section, similar to FIG. 2, of the packaging containing a product.
La fig. 4 est une vue d'un détail: Fig. 4 is a view of a detail:
les fig. 5 à 9 illustrent les diverses opérations du procédé de fabrication de cet emballage. fig. 5 to 9 illustrate the various operations of the manufacturing process for this packaging.
L'emballage représenté aux fig. 1 à 4 est constitué par une enveloppe plate, souple 10, de forme rectangulaire, dont les deux parois 11 et 12 sont soudées sur trois côtés de manière à ménager une ouverture 13 pour l'introduction et le retrait du produit. The packaging shown in fig. 1 to 4 consists of a flat, flexible envelope 10, of rectangular shape, the two walls 11 and 12 of which are welded on three sides so as to provide an opening 13 for the introduction and the withdrawal of the product.
Les parois 11 et 12 se composent chacune de deux feuilles 14, 15 qui limitent entre elles des poches 16 et 17 remplies d'air ou d'un gaz à faible pouvoir de transmission de chaleur à une pression légèrement supérieure à la pression atmosphérique. The walls 11 and 12 each consist of two sheets 14, 15 which limit between them pockets 16 and 17 filled with air or a gas with low heat transmission power at a pressure slightly higher than atmospheric pressure.
Les poches 16 et 17 sont reliées entre elles, du côté opposé à l'ouverture 13, par un passage 18. The pockets 16 and 17 are connected together, on the side opposite to the opening 13, by a passage 18.
Les feuilles 14, 15, que l'on trouve dans le commerce, sont constituées par une couche de matière plastique 19 et par une couche métallisée 20. The sheets 14, 15, which are commercially available, consist of a plastic layer 19 and a metallized layer 20.
Le produit à transporter est introduit dans l'emballage à travers l'ouverture 13 puis l'enveloppe est enroulée à partir de cette ouverture jusqu'à ce que le produit soit bien tenu, puis la partie enroulée est fixée avec un ou deux clips éventuellement avec des moyens de fermeture ad hoc incorporés ou non à l'emballage, ces moyens pouvant.être dotés d'un dispositif de préhension. Au cours de l'enroulement l'épaisseur de la couche d'air augmente plus ou moins selon le volume du produit. The product to be transported is introduced into the packaging through the opening 13, then the envelope is rolled up from this opening until the product is well held, then the rolled up part is fixed with one or two clips if necessary. with ad hoc closing means incorporated or not incorporated into the packaging, these means possibly being provided with a gripping device. During the winding the thickness of the air layer increases more or less depending on the volume of the product.
La barrière thermique formée par cette couche d'air et par la double épaisseur des parois elles-mêmes constituées par des feuilles isothermiques permet de maintenir plusieurs heures durant à des températures voisines de leurs températures de conservation les produits transportés ou stockés. The thermal barrier formed by this layer of air and by the double thickness of the walls themselves constituted by isothermal sheets makes it possible to maintain for several hours during at temperatures close to their conservation temperatures the products transported or stored.
On remarquera que cette barrière thermique ne présente pas de solution de continuité au fond de l'emballage grâce au passage 18. Ceci est particulièrement important en regard du fait que le fond des emballages isothermiques connus est généralement l'endroit où les échanges de chaleur — de l'extérieur vers l'intérieur ou inversement — sont les plus grands. It will be noted that this thermal barrier does not present a solution of continuity at the bottom of the packaging thanks to the passage 18. This is particularly important in view of the fact that the bottom of known isothermal packaging is generally the place where the heat exchanges - from outside to inside or vice versa - are the largest.
Le procédé de fabrication de l'emballage illustré aux fig. 5 à 9 est particulièrement économique. The packaging manufacturing process illustrated in figs. 5 to 9 is particularly economical.
Ce procédé consiste à partir de deux feuilles rectangulaires du type représenté à la fig. 4, dont l'une A est plus longue et plus large que l'autre B (fig. 5). à superposer ces deux feuilles, couche plastique contre couche plastique en faisant coïncider leurs petits côtés et en formant une ondulation C pour absorber l'excédent de longueur de la feuille A (fig. 6), à souder à chaud les deux feuilles le long de bandes D (fig. 7), à rabattre l'une contre l'autre les deux moitiés des s This process consists of two rectangular sheets of the type shown in FIG. 4, one of which A is longer and wider than the other B (fig. 5). to superimpose these two sheets, plastic layer against plastic layer, making their short sides coincide and forming a corrugation C to absorb the excess length of the sheet A (fig. 6), to heat-weld the two sheets along bands D (fig. 7), fold the two halves of the s against each other

deux feuilles ainsi soudées (fig. 8), à souder à chaud les bords correspondants E de la feuille A, à insuffler durant cette dernière opération de l'air ou un gaz approprié dans les poches 16 et 17 en formation. two sheets thus welded (fig. 8), to heat weld the corresponding edges E of sheet A, to breathe during this last operation air or a suitable gas into the pockets 16 and 17 in formation.

Dans une variante de ce procédé, on pourra regrouper les opérations de soudage (fig. 7 et 9) en une seule opération après avoir rabattu, en les positionnant convenablement, les deux feuilles A et B (fig. 8). In a variant of this process, the welding operations can be grouped together (fig. 7 and 9) in a single operation after having folded down, by positioning them properly, the two sheets A and B (fig. 8).
