Description

  

  
 



  Procédé pour augmenter l'isothermie d'un récipient en polystyrène expansé
 et autres mousses en matières plastiques
 Les     mousses      de matières plastiques diverses, en particulier le   polystyrène expansé  , permettent la fabrication de récipients, boîtes, caisses, etc., ayant comme caractéristiques la légèreté, la résistance aux chocs, la protection contre l'humidité et surtout l'isothermie, c'est-à-dire la protection contre les variations de température.



   Or, cette dernière propriété s'est révélée, à l'usage, très relative, en ce sens que la durée d'isolation thermique était notoirement insuffisante, par exemple valable pour quelques heures seulement alors qu'on l'espérait efficace pendant plusieurs jours.



   Cette insuffisance a pour conséquence grave l'impossibilité d'utiliser ce matériau pour la fabrication de récipients pour le transport, dans les régions tropicales, de produits chimiques et pharmaceutiques particulièrement sensibles au froid ou à la chaleur.



   Dans le but de remédier à cet inconvénient, l'invention a pour objet un procédé, visant la protection des parois d'un tel récipient contre les rayons thermiques par une enveloppe augmentant l'isothermie du polystyrène expansé et autres mousses en matière plastique.



   Pour la mise en oeuvre du procédé, il est donné deux exemples d'application:
 Le premier consiste à revtir les parois extérieures du récipient d'une mince couche d'un métal ou d'un produit réfléchissant les rayons thermiques tels que de l'aluminium mince, du papier métallisé ou un flocage de parcelles d'aluminium ou d'un autre métal, verni ou laque et autres.



   Le deuxième exemple préconise d'enfermer le récipient dans un sachet plastique dans lequel on fait le vide, au moyen d'une soudeuse de plastique.



  Ce sachet doit tre imperméable aux gaz.



   On peut appliquer aussi les deux solutions simultanément.



   REVENDICATIION
 Procédé pour augmenter l'isothermie d'un récipient en polystyrène expansé et autres mousses en matières plastiques, caractérisé en ce que les parois du récipient sont protégées par une enveloppe contre les rayons thermiques.
 



   SOUS-REVENDICATIONS
 1. Procédé suivant la revendication, caractérisé en ce que le récipient est revtu d'une couche de métal réfléchissant.



   2. Procédé suivant la revendication, caractérisé en ce que le récipient est entouré d'un sachet plastique dans lequel est fait le vide.



   3. Procédé suivant la revendication et la sousrevendication 1, caractérisé en ce que le revtement   métalliqlue    est sous forme de feuille.



   4. Procédé suivant la revendication et la sousrevendication 1, caractérisé en ce que le revtement est en papier métallisé.



   5. Procédé suivant la revendication et la sousrevendication 1, caractérisé en ce que le revtement est obtenu par flocage de parcelles de métal.



   6. Procédé suivant la revendication et les sousrevendications 1, 3 à 5, caractérisé en ce que le métal est de l'aluminium.

  Process for increasing the isothermal energy of an expanded polystyrene container
 and other plastic foams
 Foams of various plastic materials, in particular expanded polystyrene, allow the manufacture of containers, boxes, cases, etc., having as characteristics lightness, impact resistance, protection against humidity and especially isothermal, c 'that is to say protection against temperature variations.



   However, this last property has proved, in use, very relative, in the sense that the duration of thermal insulation was notoriously insufficient, for example valid for a few hours only whereas it was hoped to be effective for several days. .



   The serious consequence of this insufficiency is the impossibility of using this material for the manufacture of containers for the transport, in tropical regions, of chemical and pharmaceutical products which are particularly sensitive to cold or to heat.



   With the aim of remedying this drawback, the subject of the invention is a method aimed at protecting the walls of such a container against thermal rays by an envelope increasing the isothermal nature of the expanded polystyrene and other plastic foams.



   For the implementation of the method, two application examples are given:
 The first is to coat the outer walls of the container with a thin layer of a metal or a heat reflective product such as thin aluminum, foil, or flocking of foil or foil. another metal, varnished or lacquered and others.



   The second example recommends enclosing the container in a plastic bag in which a vacuum is made, using a plastic sealer.



  This bag must be impermeable to gases.



   The two solutions can also be applied simultaneously.



   CLAIM
 Process for increasing the isothermal energy of a container made of expanded polystyrene and other plastic foams, characterized in that the walls of the container are protected by an envelope against thermal rays.
 



   SUB-CLAIMS
 1. Method according to claim, characterized in that the container is coated with a layer of reflective metal.



   2. Method according to claim, characterized in that the container is surrounded by a plastic bag in which a vacuum is created.



   3. Method according to claim and subclaim 1, characterized in that the metallic coating is in the form of a sheet.



   4. Method according to claim and subclaim 1, characterized in that the coating is metallized paper.



   5. Method according to claim and subclaim 1, characterized in that the coating is obtained by flocking of pieces of metal.



   6. A method according to claim and subclaims 1, 3 to 5, characterized in that the metal is aluminum.
