La présente invention a encore pour objet un procédé de fabrication dudit matériau stratifié par les techniques papetières. The present invention also relates to a process for manufacturing said laminated material by paper techniques.
D'autres buts et avantages de l'invention apparaîtront à la lecture de la description suivante et des figures jointes données à titre illustratif et nullement limitatif. Other objects and advantages of the invention will appear on reading the following description and the appended figures given by way of illustration and in no way limitative.
- les figures 1 et 2 représentent différents modes de
réalisation du matériau stratifié selon
l'invention;
- les figures 3 à 5 représentent des emballages formés du
matériau stratifié selon la figure 1.- Figures 1 and 2 show different modes of
production of the laminated material according to
the invention;
- Figures 3 to 5 show packaging formed of
laminate material according to figure 1.
Sur la figure 1, est représenté un matériau stratifié 1 formé de deux couches de carton ondulé 2 entre lesquelles est disposé un sandwich 3 formé de deux feuilles d'aluminium 4 dont la face, en regard des couches de carton, est revêtue de polyéthylène. Entre les deux feuilles d'aluminium, sont placées deux feuilles 5 de polyéthylène dont la surface comporte une multitude de zones repoussées de sorte que des bulles d'air soient incluses entre ces deux feuilles. In Figure 1, there is shown a laminated material 1 formed of two layers of corrugated cardboard 2 between which is disposed a sandwich 3 formed of two sheets of aluminum 4 whose face, facing the layers of cardboard, is coated with polyethylene. Between the two aluminum sheets, two sheets of polyethylene are placed, the surface of which has a multitude of repelled zones so that air bubbles are included between these two sheets.
En fait, le sandwich 3 formé des deux feuilles d'aluminium 4 et des deux feuilles de polyéthylène 5 présente une épaisseur totale de 8 mm environ. La résistance thermique de ce sandwich est de 1,32 m2K/W et une résistance à l'humidité de l'ordre de 4 000 Mns/qm. Dans le test de résistance au feu, il est classé dans la classe 1. Ce sandwich est imper méable, imputrescible, résistant et tenace. In fact, the sandwich 3 formed from the two aluminum sheets 4 and the two polyethylene sheets 5 has a total thickness of approximately 8 mm. The thermal resistance of this sandwich is 1.32 m2K / W and a humidity resistance of the order of 4000 Mns / qm. In the fire resistance test, it is classified in class 1. This sandwich is waterproof, rotproof, resistant and tenacious.
La figure 2 représente un matériau stratifié 2 formé de trois couches de carton ondulé, la couche intermédiaire 2' pouvant présenter une épaisseur inférieure à celle des deux couches 2 extrêmes. Dans l'intervalle formé entre chaque couple de couches de carton ondulé, est disposé un sandwich 3 du type précité. FIG. 2 represents a laminated material 2 formed from three layers of corrugated cardboard, the intermediate layer 2 ′ possibly having a thickness less than that of the two extreme layers 2. In the interval formed between each pair of layers of corrugated cardboard, a sandwich 3 of the aforementioned type is placed.
L'épaisseur du matériau stratifié 1 representé sur la figure 1 est de l'ordre de 12 à 16 mm et l'épaisseur du matériau stratifié 6 représenté sur la figure 2 est de l'ordre de 16 à 32 mm. The thickness of the laminate material 1 shown in Figure 1 is in the range of 12 to 16 mm and the thickness of the laminate material 6 shown in Figure 2 is in the range of 16 to 32 mm.
Le matériau représenté sur la figure 1 est employe pour former des emballages du type des caisses en carton, ces emballages étant représentés sur les figures 3 à 5 par une coupe selon leur plan longitudinal médian. The material shown in Figure 1 is used to form packages of the type of cardboard boxes, these packages being shown in Figures 3 to 5 by a section along their median longitudinal plane.
Les emballages 11 représentés en coupe sur ces figures à 5 contiennent des pots 7' de yaourts regroupés par packs 7 de 12 ou 16 pots disposés sur deux hauteurs. La masse totale des yaourts est de 15 kg et la masse totale, emballage inclus, de chacun de ces emballages est de 16 kg. The packages 11 shown in section in these figures to 5 contain pots 7 'of yoghurt grouped by packs 7 of 12 or 16 pots arranged on two heights. The total mass of the yogurts is 15 kg and the total mass, including packaging, of each of these packages is 16 kg.
Sur la figure 3, sont représentés quatre sondes à thermocouples 8 placés entre deux pots de packs différents et destins à suivre l'évolution de la température avec le temps. In FIG. 3, four thermocouple probes 8 are represented, placed between two jars of different packs and intended to follow the evolution of the temperature over time.
Sur les figures 4 et 5, les thermocouples 8 ne sont pas représentés; il est évident cependant qu'ils sont employés tout comme dans le cas de la figure 3 pour suivre l'évolution de la température avec le temps. In FIGS. 4 and 5, the thermocouples 8 are not shown; it is obvious however that they are used just as in the case of figure 3 to follow the evolution of the temperature with time.
Dans le mode de réalisation représenté sur la figure 4, deux poches 9 de glace sont placées dans la partie inférieure de l'emballage et trois poches 9 de glace sont placées dans la partie supérieure de cet emballage. Elles sont séparées des packs 7 par une plaque de carton 10. In the embodiment shown in Figure 4, two ice pockets 9 are placed in the lower part of the package and three ice pockets 9 are placed in the upper part of this package. They are separated from the packs 7 by a cardboard plate 10.
Dans le mode de réalisation représenté sur la figure 5, le même nombre de poches 9 est placé dans le carton mais selon une disposition différente, à savoir: une dans la partie inférieure, deux dans la partie supérieure et une dans chaque partie extrême. Une plaque de carton 10 sépare chacune des poches 9 des packs 7. In the embodiment shown in Figure 5, the same number of pockets 9 is placed in the carton but in a different arrangement, namely: one in the lower part, two in the upper part and one in each end part. A cardboard plate 10 separates each of the pockets 9 from the packs 7.
Le volume de ces poches de glace est de 1 litre et elles sont rectangulaires, leur dimension étant 30 x 20 cm. The volume of these ice packs is 1 liter and they are rectangular, their size being 30 x 20 cm.
On suit l'évolution de la température du contenu, la température initiale du contenu étant de 4 C + 1 C et, dans le cas des figures 4 et 5, la température initiale de la glace contenue dans les poches étant comprise entre -20 et -25 C. La température extérieure est de 35 C. The temperature of the content is followed, the initial temperature of the content being 4 ° C. + 1 ° C. and, in the case of FIGS. 4 and 5, the initial temperature of the ice contained in the bags being between -20 and -25 C. The outside temperature is 35 C.
Les quatre sondes à thermocouple sont connectées à un enregistreur graphique. The four thermocouple probes are connected to a graphic recorder.
Le tableau ci-dessous montre l'évolution de la température en fonction du temps pour des essais effectués dans les mêmes conditions de température externe. The table below shows the evolution of the temperature as a function of time for tests carried out under the same external temperature conditions.
