249 1825249 1825
La présente invention a pour objet un récipient dont la paroi est constituée d'au moins deux couches d'un même polymère. Il est connu d'utiliser des récipients dont la paroi est constituée de plusieurs couches de polymères différents, pour le conditionnement de produits sensibles à la lumière et/ou aux gaz, comme l'oxygène de l'aire notamment les The present invention relates to a container whose wall consists of at least two layers of the same polymer. It is known to use containers whose wall consists of several layers of different polymers, for the packaging of products sensitive to light and / or gases, such as oxygen in the area including the
produits alimentaires.foodstuffs.
Le brevet français n0 2 132 395 décrit ainsi une bouteille constituée par une couche de polyamide et une couche de polyolèfine sur laquelle est greffé un acide dicarboxylique. Cette bouteille est notamment utilisée pour le conditionnement de produits alimentaires. Cette bouteille est obtenue par le procédé bien connu de coextrusion soufflage. Dans ce cas, la protection aux gaz est obtenue par la couche de polyamide, le polyéthylène French Patent No. 2,132,395 thus describes a bottle constituted by a polyamide layer and a polyolefin layer on which a dicarboxylic acid is grafted. This bottle is used in particular for the packaging of food products. This bottle is obtained by the well known method of coextrusion blowing. In this case, the gas protection is obtained by the polyamide layer, the polyethylene
étant perméable aux gaz.being permeable to gases.
La Demanderesse a établi qu'il est possible de réaliser, pour le conditionnement de produits sensibles à la lumière et aux gaz, des récipients à paroi multicouche d'un même polymère, et que ces récipients se distinguent avantageusement des récipients connus, dont la paroi est The Applicant has established that it is possible to produce multilayer wall containers of the same polymer for the packaging of products sensitive to light and gases, and that these containers are advantageously distinguished from known containers whose wall is
constituée de couches de polymères différents. made of layers of different polymers.
Le but de la présente invention est donc de proposer des récipients pour le conditionnement de produits sensibles The object of the present invention is therefore to provide containers for the packaging of sensitive products.
à la lumière et, éventuellement, aux gaz. in the light and, possibly, the gases.
A cet effet, l'invention a pour objet un récipient caractérisé en ce que sa paroi comprend au moins: a) une première couche extérieure d'un polymère thermoplastique contenant une charge telle que ladite première couche est apte à arrêter les rayons lumineux d'une longueur d'onde égale ou supérieure à 800 manomètres, b) une deuxième couche du même polymère thermoplastique contenant une charge telle que ladite deuxième couche est apte à arrêter les rayons lumineux d'une longueur d'onde For this purpose, the subject of the invention is a container characterized in that its wall comprises at least: a) a first outer layer of a thermoplastic polymer containing a filler such that said first layer is capable of stopping the light rays of a wavelength equal to or greater than 800 nanometers, b) a second layer of the same thermoplastic polymer containing a charge such that the said second layer is capable of stopping the light rays of a wavelength
inférieure à 800 nanomètres.less than 800 nanometers.
Les deux couches de la paroi arrêtent ainsi toutes les radiations lumineuses et l'effet de ces radiations -2- The two layers of the wall thus stop all the luminous radiations and the effect of these radiations -2-
sur le contenu du récipient est nul. on the contents of the container is void.
L'arrgt des radiations peut se faire par réflexion The stop of radiation can be done by reflection
ou par absorption.or by absorption.
Le fait que les deux polymères soient identiques supprime le phénomène d'incompatibilité qui peut exister quand ils sont différents, ce qui nécessite alors la The fact that the two polymers are identical eliminates the phenomenon of incompatibility that may exist when they are different, which then requires the
présence d'une couche adhésive.presence of an adhesive layer.
Les polymères pouvant constituer les couches du récipient selon l'invention peuvent être des polymères The polymers that can constitute the layers of the container according to the invention can be polymers
perméables ou imperméables aux gaz. permeable or impervious to gases.
Il peut s'agir, par exemple, de polyoléfines comme le polyéthylène haute ou basse densité, le polypropylène It may be, for example, polyolefins such as high or low density polyethylene, polypropylene
ou le polybutène.or polybutene.
La première couche peut contenir entre 0,5 et 30 % The first layer can contain between 0.5 and 30%
et, de préférence, entre 0,5 et 10 % en poids de charge. and preferably between 0.5 and 10% by weight filler.
Celle-ci peut être notamment une charge de couleur blanche ou très claire, comme le dioxyde de titane, le This can be in particular a charge of white or very light color, such as titanium dioxide,
carbonate de calcium, l'oxyde de zinc. calcium carbonate, zinc oxide.
Par son pouvoir réfléchissant, elle évite l'élévation de la température du produit contenu dans le récipient sous l'effet des rayons lumineux de longueur d'onde supérieure By its reflective power, it avoids the elevation of the temperature of the product contained in the container under the effect of the light rays of higher wavelength
à 800 nanomètres.at 800 nanometers.
La deuxième couche peut contenir entre 0,01 et 20 % The second layer can contain between 0.01 and 20%
et, de préférence, entre 0,1 et 5 % en poids de charge. and, preferably, between 0.1 and 5% by weight of filler.
Cette charge peut être notamment le noir de carbone. This charge can be in particular carbon black.
Le récipient selon l'invention peut être utilisé pour le conditionnement de tous les produits susceptibles de se dégrader sous l'action de la lumière. Dans le cas de produits alimentaires, il est naturellement nécessaire que le polymère constituant la couche en contact avec The container according to the invention can be used for the packaging of all products liable to degrade under the action of light. In the case of food products, it is of course necessary that the polymer constituting the layer in contact with
l'aliment soit de nature dite "alimentaire". the food is of so-called "food" nature.
Il peut être également nécessaire que le récipient comprenne une troisième couche supplémentaire interne du même polymère, afin d'éviter le contact de l'aliment avec la charge contenue dans la deuxième couche, et que cette troisième couche ne contienne pas de charge, ou contienne It may also be necessary for the container to comprise a third additional inner layer of the same polymer, in order to avoid contact of the food with the load contained in the second layer, and that this third layer contains no load, or contains
une charge de nature "alimentaire".a load of "food" nature.
Le récipient selon l'invention peut être constitué - par The container according to the invention can be constituted by
249 1825249 1825
exemple, dans le cas o il est destiné au conditionnement du lait - de trois couches de polyéthylène haute densité: a) une première couche extérieure contenant du dioxyde de titane, b) une deuxième couche intermédiaire contenant du noir de carbone, c) une troisième couche intérieure contenant, ou ne example, in the case where it is intended for the conditioning of milk - of three layers of high density polyethylene: a) a first outer layer containing titanium dioxide, b) a second intermediate layer containing carbon black, c) a third inner layer containing, or not
contenant pas, du dioxyde de titane. not containing titanium dioxide.
Dans ce cas, l'épaisseur de la couche extérieure peut 4tre comprise entre 50 et 400 microns, celle de la couche intermédiaire entre 100 et 300 microns, celle de la couche In this case, the thickness of the outer layer may be between 50 and 400 microns, that of the intermediate layer between 100 and 300 microns, that of the layer
intérieure entre 50 et 400 microns. between 50 and 400 microns.
Comme il a été indiqué précédemment, ces récipients peuvent 8tre obtenus par le procédé de coextrusion-soufflage, o chaque couche est obtenue à partir d'une extrudeuse distincte quand les polymères constituant ces couches As indicated above, these containers can be obtained by the coextrusion-blow molding process, where each layer is obtained from a separate extruder when the polymers constituting these layers.
comportent des charges différentes. have different loads.
Dans le cas o les polymères constituant deux couches sont chargés de manière identique-(cas des bouteilles de lait décrit ci-dessus),le récipient peut 4tre obtenu à In the case where the polymers constituting two layers are loaded in an identical manner (in the case of the milk bottles described above), the container can be obtained from
partir de deux extrudeuses pour trois couches. from two extruders for three layers.
En effet, la présence de dioxyde de titane n'est pas Indeed, the presence of titanium dioxide is not
g4nante pour le lait dans la couche interne. G4nante for the milk in the inner layer.
L'exemple qui suit, qui n'a aucun caractère limitatif, The following example, which has no limiting character,
est destiné à illustrer l'invention. is intended to illustrate the invention.
EXEMPLEEXAMPLE
Cet exemple concerne la description d'un récipient This example concerns the description of a container
selon l'invention et son application au conditionnement et according to the invention and its application to conditioning and
à la conservation du lait.to the preservation of milk.
On réalise par coextrusion des bouteilles tricouches en polyéthylène haute densité.de densité d = o,960, de masse moléculaire en nombre Mn = 13 000 et de masse Three-ply high density polyethylene bottles of density = 0.960, with a number-average molecular weight Mn = 13 000 and mass are produced by coextrusion.
moléculaire en poids Me = 120 000.molecular weight Me = 120,000.
La couche extérieure a une épaisseur de 100 microns The outer layer has a thickness of 100 microns
environ et contient 3 % en poids de dioxyde de titane. approximately and contains 3% by weight of titanium dioxide.
La couche intermédiaire a une épaisseur de 300 microns The intermediate layer has a thickness of 300 microns
environ et contient 2 % en poids de noir de carbone. about and contains 2% by weight of carbon black.
La couche intérieure est identique à la couche -4- extérieure. Ces bouteilles ont été remplies par du lait préstérilisé à 1300C, pendant 4 secondes. Après bouchage des bouteilles par une capsule constituée d'un complexe d'aluminium (épaisseur 50 microns) et de polyéthylène contenant, à l'état greffé, moins de 5 % en poids d'acide acrylique (épaisseur 50 microns), les bouteilles ont été portées à The inner layer is identical to the outer layer. These bottles were filled with pre-sterilized milk at 1300C for 4 seconds. After capping the bottles with a capsule consisting of an aluminum complex (thickness 50 microns) and polyethylene containing, in the grafted state, less than 5% by weight of acrylic acid (thickness 50 microns), the bottles have been brought to
1200C pendant 20 minutes.1200C for 20 minutes.
Ces bouteilles ont été exposées à la lumière naturelle, These bottles were exposed to natural light,
à 200C environ, pendant 3 mois.at 200C, for 3 months.
A la fin de cette période, le lait est toujours d'excellente qualité, ce qui n'est pas le cas avec des bouteilles constituées d'une couche de polyéthylène sans At the end of this period, the milk is always of excellent quality, which is not the case with bottles made of a layer of polyethylene without
charge, o la conservation du lait est d'environ 2 jours. load, o the storage of milk is about 2 days.
Il faut remarquer que les bouteilles testées sont des bouteilles perméables à l'air et que le lait contient de l'oxygène. On peut penser que les réactions d'oxydation ne se produisent pas, car la catalyse des réactions d'oxydation par la lumière ne se produit pas, en raison de la présence des charges contenues dans les différentes It should be noted that the bottles tested are bottles permeable to air and that the milk contains oxygen. It may be thought that the oxidation reactions do not occur because the catalysis of light oxidation reactions does not occur due to the presence of the charges contained in the different
couches de polymère.polymer layers.
