Definitions

  • Another object of the invention is to provide a collection and transport container for the container materials obtained in the unpolluted state.
  • containers made of polymers such as polyethylene (PE), polypropylene (PP), polystyrene (PS), polyamides (PA), polyester, polyacrylonitrile (PAN), polyether, polyvinyl chloride (PVC), polyvinylidene chloride (PVDC), ethylene-vinyl alcohol copolymers (EVOH), polyvinyl alcohol (PVAL), and their mixtures and copolymers with one another and with other copolymerizable ethylenically unsaturated monomers.
  • PE polyethylene
  • PP polypropylene
  • PS polystyrene
  • PA polyamides
  • PET polyacrylonitrile
  • PAN polyether
  • PVC polyvinyl chloride
  • PVDC polyvinylidene chloride
  • EVOH ethylene-vinyl alcohol copolymers
  • PVAL polyvinyl alcohol
  • Container walls according to the invention are preferably produced from layers of polyethylene, polypropylene and polystyrene, and their mixtures and copolymers.
  • polystyrene will increasingly take a back seat, because for health reasons, especially in food packaging, the residual monomer content, i.e. the rest of the unreacted styrene must be reduced to a minimum.
  • this reduction in the residual monomer content is very complex and therefore expensive, so that plastics such as polyethylene, polypropylene and their copolymers are preferred.
  • the ratio of PE homopolymer to the second component of the blend is in the range of 70:30 to 30:70, preferably 60:40 to 40:60, and more preferably about 50:50.
  • the containers according to the invention can be used for packaging a wide variety of goods, including liquid, pasty, powdery, granular or solid substances.
  • the collection and transport container is preferably designed as an all-plastic box or as a corrugated plastic box and consists of the same thermoplastic materials from which the carrier layers of the containers according to the invention are made.
  • a recyclate material made from carrier layers of the containers according to the invention is preferably used to produce the collection and transport containers. Providing households with these containers as widely as possible immediately results in a main area of application for the recycled material.
  • the present invention thus provides a container 10 which can be produced in a simple and inexpensive manner and the wall of which consists of a carrier layer 11, an inner layer 12 and optionally at least one further layer 13 which adhere to one another and the inner layer 12 can be separated by a predetermined force.
  • the inner layer 12 and the optionally further layer 13 or layers 13 protect the carrier layer 11, which comprises the predominant proportion of the container material, from contamination with the filling material and can, after removal of the filling material and removal of the inner layer 12 and possibly existing further layer 13, provided that it is in the form of a printed, separable layer on the outside of the container, is obtained in pure form and is fed to new high-quality products by recycling.

Abstract

Un récipient en matières plastiques recyclables est fabriqué de manière simple et économique par co-extrusion suivie de thermoformage, et comprend une paroi constituée d'une couche de support (11), d'une couche intérieure (12) et le cas échéant d'au moins une couche supplémentaire (13-18) qui adhèrent les unes aux autres, certaines couches pouvant être détachées par une force prédéterminée. La couche intérieure (12) et le cas échéant la couche supplémentaire (13) ou les couches supplémentaires (13-18) protègent la couche de support (11), qui constitue le pourcentage le plus élevé de matériau constitutif du récipient, d'une contamination par les matières de remplissage. La couche de support (11) peut ainsi être gardée dans sa forme pure et être recyclée afin de fabriquer de nouveaux produits de haute qualité, une fois que les matières de remplissage ont été prélevées et que la couche intérieure (12), ainsi que des couches supplémentaires éventuelles (18-18), ont été elevées. Un conteneur de collecte et de transport de ces récipients permet de les collecter, de les transporter et de les recycler de manière efficace. L'invention concerne en outre un procédé de fabrication simple et économique de ce récipient.

Claims (10)

  1. Récipient à parois multiples (10), fabrique avec une feuille plane coextrudée et soumis à un processus de formage à chaud consécutif, le récipient (10) comprenant une couche de support (11), une couche intérieure (12) et, le cas échéant, au moins une autre couche (13-18), lesquelles collent les unes contre les autres à la sortie du processus de coextrusion, dans lequel la couche intérieure (12) est au moins disposée dans la zone de la couche de support (11), qui entrerait sinon en contact avec l'intérieur du récipient, et dans lequel l'adhérence de chaque couche (11-18) peut être ajustée par le processus de coextrusion et la couche intérieure (12), ainsi qu'une autre couche (13-18) disposée le cas échéant sur la paroi extérieure du récipient, est (sont) détachables(s) par une force prédéfinie.
  2. Récipient selon la revendication 1, dans lequel la couche de support (11) de la paroi du récipient confère essentiellement l'ensemble de la stabilité dimensionnelle et de la résistance et est nettement plus épaisse que la couche intérieure (12) et, le cas échéant, les différentes autres couches (13-18).
  3. Récipient selon la revendication 1 ou 2, le récipient pouvant être stérilisé.
  4. Récipient selon l'une quelconque des revendications précédentes, dans lequel au moins une des autres couches (13-18) est une couche isolante.
  5. Récipient selon l'une quelconque des revendications précédentes, dans lequel l'adhérence entre la couche intérieure (12), une des autres couches (13-18), disposée le cas échéant sur la paroi extérieure du récipient, et chaque couche contigue est comprise entre 0,5 et 10 N/cm².
  6. Récipient selon l'une quelconque des revendications précédentes, dans lequel la couche intérieure (12) est une couche copolymère de polyéthylène et polypropylène ou une couche homopolymère de polypropylène.
  7. Récipient selon l'une quelconque des revendications précédentes, dans lequel la couche qui est en contact avec la couche intérieure (12) est une couche formée d'un mélange de copolymère polyéthylène et polypropylène et d'homopolymère polyéthylène dans un rapport exprimé en pourcentage en poids de 70:30 à 30:70.
  8. Procédé de fabrication d'un récipient selon l'une quelconque des revendications précédentes, dans lequel on fabrique un produit de co-extrusion qui constituera plus tard toutes les couches du futur récipient et dans lequel le produit de co-extrusion plat obtenu est ensuite soumis à un processus de formage à chaud pour le formage du récipient.
  9. Conteneur de stockage et conteneur de transport (50 ; 51) comprenant des récipients (10) selon l'une quelconque des revendications 1 à 7, le conteneur étant essentiellement formé du même matériau synthétique que celui choisi pour la couche de support (11) du récipient (10).
  10. Utilisation d'un récipient selon l'une quelconque des revendications 1 à 7, pour le conditionnement des produits alimentaires, des boissons, des produits pharmaceutiques ou cosmétiques.
