Description
La présente invention concerne un récipient , notamment pour produit alimentaire, dont la paroi est recouverte au moins partiellement par une étiquette comprenant une couche externe portant des signes visibles de l'extérieur et une couche interne fixée par adhérence sur la paroi.The present invention relates to a container, in particular for a food product, the wall of which is covered at least partially by a label comprising an external layer bearing signs visible from the outside and an internal layer fixed by adhesion to the wall.
Les étiquettes portées par les récipients pour produits alimentaires sont généralement fixées de façon définitive, de sorte qu'il est pratiquement impossible de les enlever sans risquer de les déchirer.The labels carried by containers for food products are generally permanently fixed, so that it is practically impossible to remove them without risking tearing them apart.
Il existe pourtant des raisons pour lesquelles un enlèvement aisé des étiquettes apposées sur les récipients peut être nécessaire.There are, however, reasons why easy removal of labels from containers may be necessary.
Ces raisons peuvent par exemple être d'ordre écologique afin de permettre un tri des parties constitutives des récipients mis aux ordures et de faciliter ainsi les opérations de recyclage. Elles peuvent également être d'ordre éducatif ou ludique lorsque les étiquettes portent sur leur face visible des images susceptibles d'être collectionnées ou lorsqu'elles portent sur leur face invisible des mots croisés, des devinettes, des numéros de loterie, etc...These reasons may for example be ecological in order to allow sorting of the constituent parts of the containers put in the garbage and thus facilitate recycling operations. They can also be educational or fun when the labels bear on their visible side images likely to be collected or when they bear on their invisible side crosswords, riddles, lottery numbers, etc.
La présente invention se propose de permettre un tel enlèvement et, pour ce faire, elle a pour objet un récipient, notamment pour produit alimentaire, dont la paroi est recouverte au moins partiellement par une étiquette comprenant une couche externe portant des signes visibles de l'extérieur et une couche interne fixée par adhérence sur la paroi, et qui est caractérisé en ce que l'étiquette comprend une couche intermédiaire située entre la couche externe et la couche interne, la force d'adhérence de la couche intermédiaire vis-à-vis des couches externe et interne étant inférieure à la force d'adhérence de la couche interne vis-à-vis de la paroi.The present invention proposes to allow such removal and, to do this, it relates to a container, in particular for food product, the wall of which is covered at least partially by a label comprising an outer layer bearing visible signs of the outer layer and an inner layer fixed by adhesion to the wall, and which is characterized in that the label comprises an intermediate layer located between the outer layer and the inner layer, the adhesive strength of the intermediate layer vis-à-vis outer and inner layers being less than the adhesive strength of the inner layer vis-à-vis the wall.
Grâce à la couche intermédiaire, la couche externe peut être facilement séparée de la couche interne qui reste quant à elle solidaire du récipient.Thanks to the intermediate layer, the outer layer can be easily separated from the inner layer which remains as to it secured to the container.
Des images imprimées sur la face visible de l'étiquette peuvent donc être récupérées et collectionnées. De même, des mots croisés, des devinettes, des numéros de loterie, etc... prévus sur la face interne de la couche externe peuvent être découverts et utilisés.Images printed on the visible side of the label can therefore be recovered and collected. Likewise, crosswords, riddles, lottery numbers, etc. provided on the inner face of the outer layer can be discovered and used.
Selon un premier mode de réalisation de l'invention, la couche intermédiaire est constituée d'un produit à base de silicone, par exemple une huile de silicone de type polysiloxane, et a une épaisseur de l'ordre de 1 à 3 g/m2.According to a first embodiment of the invention, the intermediate layer consists of a silicone-based product, for example a silicone oil of the polysiloxane type, and has a thickness of the order of 1 to 3 g / m 2 .
Selon un deuxième mode de réalisation de l'invention, la couche intermédiaire est constituée d'un mélange d'une résine de polymère et d'un additif à base de silicone.According to a second embodiment of the invention, the intermediate layer consists of a mixture of a polymer resin and a silicone-based additive.
De préférence, la résine de polymère est choisie dans le groupe constitué par les vernis à base de nitrocellulose, les résines vinyliques, les résines acryliques et les résines de polyester.Preferably, the polymer resin is chosen from the group consisting of nitrocellulose-based varnishes, vinyl resins, acrylic resins and polyester resins.
On notera ici que la couche intermédiaire de ce mode de réalisation peut avoir une épaisseur de l'ordre de 3 à 5 g/m2.It will be noted here that the intermediate layer of this embodiment can have a thickness of the order of 3 to 5 g / m 2 .
Selon un troisième mode de réalisation de l'invention, la matière constituant la couche intermédiaire possède un pouvoir adhérent permanent tandis que son épaisseur peut être de l'ordre de 4 à 7 g/m2.According to a third embodiment of the invention, the material constituting the intermediate layer has a permanent adhesive power while its thickness can be of the order of 4 to 7 g / m 2 .
Comme la matière utilisée pour réaliser la couche intermédiaire de ce mode de réalisation possède un pouvoir adhérent permanent, l'étiquette peut bien entendu être enlevée et remise en place plusieurs fois.As the material used to make the intermediate layer of this embodiment has a permanent adhesive power, the label can of course be removed and replaced several times.
Selon un quatrième mode de réalisation, la couche intermédiaire est constituée d'un érucamide ou d'un oléamide.According to a fourth embodiment, the intermediate layer consists of an erucamide or an oleamide.
Le récipient selon la présente invention se caractérise en outre en ce que la couche interne de l'étiquette peut être constituée par un produit thermofusible scellable à une température d'environ 70°C.The container according to the present invention is further characterized in that the inner layer of the label can be constituted by a hot-melt product which can be sealed at a temperature of approximately 70 ° C.
Lorsque le récipient est réalisé par thermoformage d'une matière plastique, la chaleur de thermoformage est en effet normalement suffisante pour faire fondre superficiellement le produit constituant la couche interne et permettre la réalisation d'une liaison solide par adhérence entre celle-ci et la paroi du récipient.When the container is made by thermoforming a plastic material, the thermoforming heat is indeed normally sufficient to melt the product constituting the internal layer superficially and allow the creation of a solid bond by adhesion between the latter and the wall of the container.
Lorsque le récipient n'est pas en matière plastique et/ou n'est pas réalisé par thermoformage, il convient par contre de le chauffer suffisamment pour faire fondre superficiellement le produit constituant la couche interne et le faire adhérer au récipient.When the container is not made of plastic and / or is not produced by thermoforming, it should however be heated enough to melt the product constituting the inner layer superficially and cause it to adhere to the container.
Deux modes d'exécution de la présente invention seront décrits ci-après à titre d'exemples nullement limitatifs en référence au dessin annexé dans lequel :
- la figure 1 est une vue en perspective schématique d'un récipient pour produit alimentaire conforme à l'invention, portant une étiquette recouvrant une surface limitée de sa paroi latérale, cette étiquette pouvant être facilement enlevée sous l'action d'une traction ;
- la figure 2 est une vue en coupe schématique partielle et à échelle agrandie, réalisée selon la ligne II-II de la figure 1, les épaisseurs des couches constituant l'étiquette étant exagérées afin de mieux faire comprendre l'invention ; et
- la figure 3 est une vue en perspective schématique d'un pot de yaourt conforme à l'invention, ce pot portant une étiquette dont les deux extrémités se chevauchent lorsqu'elle est en place.
- Figure 1 is a schematic perspective view of a container for food product according to the invention, carrying a label covering a limited surface of its side wall, this label can be easily removed under the action of traction;
- Figure 2 is a partial schematic sectional view on an enlarged scale, taken along line II-II of Figure 1, the thicknesses of the layers constituting the label being exaggerated in order to better understand the invention; and
- Figure 3 is a schematic perspective view of a yogurt pot according to the invention, this pot carrying a label whose two ends overlap when it is in place.
Le récipient représenté sur la figure 1 est un récipient classique réalisé en matière plastique, dont la paroi latérale 1 est solidaire d'un fond circulaire et dont l'entrée est fermée par un couvercle 2 pourvu d'une jupe 3.The container shown in FIG. 1 is a conventional container made of plastic, the side wall 1 of which is secured to a circular bottom and the inlet of which is closed by a cover 2 provided with a skirt 3.
Il porte une étiquette 4 recouvrant une surface limitée de sa paroi latérale 1 et pouvant être facilement arrachée à la main.It carries a label 4 covering a limited surface of its side wall 1 and which can be easily torn off by hand.
Comme on le voit clairement sur la figure 2, l'étiquette 4 comprend une couche externe 5 portant des signes 6 visibles de l'extérieur, une couche interne 7 fixée par adhérence sur la paroi latérale 1 du récipient, et une couche intermédiaire 8 située entre la couche externe 5 et la couche interne 7.As can be clearly seen in FIG. 2, the label 4 comprises an outer layer 5 bearing signs 6 visible from the outside, an inner layer 7 fixed by adhesion to the side wall 1 of the container, and an intermediate layer 8 located between the outer layer 5 and the inner layer 7.
Pour que l'étiquette 4 puisse être facilement arrachée, la force d'adhérence de la couche intermédiaire vis-à-vis des couches externe et interne doit être inférieure à la force d'adhérence de la couche interne vis-à-vis de la paroi latérale 1 du récipient.So that the label 4 can be easily torn off, the adhesive force of the intermediate layer vis-à-vis the external and internal layers must be less than the adhesive force of the internal layer vis-à-vis the side wall 1 of the container.
A titre indicatif, on précisera que la différence entre les forces d'adhérence ci-dessus peut résulter d'un manque d'affinité physique ou chimique entre les couches externe et intermédiaire et/ou entre les couches intermédiaire et interne, ainsi que d'une grande différence de tension de surface entre les couches externe et intermédiaire et/ou entre les couches intermédiaire et interne.As an indication, it will be specified that the difference between the above adhesion forces may result from a lack of physical or chemical affinity between the outer and intermediate layers and / or between the intermediate and inner layers, as well as from a large difference in surface tension between the outer and middle layers and / or between the middle and inner layers.
La matière utilisée pour réaliser la couche intermédiaire peut être constituée d'un produit à base de silicone, par exemple d'une huile de silicone de type polysiloxane, et avoir une épaisseur de l'ordre de 1 à 3 g/m2. Un tel produit peut par exemple être le PERENOL commercialisé par la société HENKEL.The material used to make the intermediate layer may consist of a silicone-based product, for example a silicone oil of the polysiloxane type, and have a thickness of the order of 1 to 3 g / m 2 . Such a product can for example be PERENOL sold by the company HENKEL.
Cette matière peut également être constituée d'un mélange d'une résine de polymère et d'un additif à base de silicone, la résine de polymère étant choisie de préférence dans le groupe constitué par les vernis à base de nitrocellulose, les résines vinyliques, les résines acryliques et les résines de polyester. Elle est dans ce cas appliquée sous la forme d'une couche dont l'épaisseur est de préférence de l'ordre de 3 à 5 g/m2.This material can also consist of a mixture of a polymer resin and a silicone-based additive, the polymer resin preferably being chosen from the group consisting of nitrocellulose-based varnishes, vinyl resins, acrylic resins and polyester resins. It is in this case applied in the form of a layer whose thickness is preferably of the order of 3 to 5 g / m 2 .
Elle peut par ailleurs être constituée par une matière possédant un pouvoir adhérent permanent et former une couche dont l'épaisseur est de l'ordre de 4 à 7 g/m2.It can also be constituted by a material having a permanent adhesive power and form a layer whose thickness is of the order of 4 to 7 g / m 2 .
Lorsque l'on exerce une traction sur l'étiquette afin de la séparer du récipient, la couche interne 7 reste sur la paroi latérale 1, comme représenté sur la figure 1. Quant à la couche intermédiaire 8, elle peut soit rester sur la couche externe 5, soit rester sur la couche interne 7, soit se répartir sur la couche externe et sur la couche interne.When pulling on the label in order to separate it from the container, the internal layer 7 remains on the side wall 1, as shown in FIG. 1. As for the intermediate layer 8, it can either remain on the outer layer 5, either remain on the inner layer 7, or spread over the outer layer and over the inner layer.
Lorsque la face de la couche externe 5 qui est tournée vers la couche intermédiaire 8 est imprimée, ses impressions deviennent visibles après l'enlèvement de la couche externe 5, ce qui peut constituer un élément attractif pour les consommateurs.When the face of the outer layer 5 which faces the intermediate layer 8 is printed, its impressions become visible after the removal of the outer layer 5, which can be an attractive element for consumers.
Pour faciliter l'arrachement, l'étiquette pourrait comporter une zone n'adhérant pas ou pratiquement pas à la paroi latérale du récipient. Cette zone pourrait être située au niveau d'un coin de l'étiquette dans lequel la matière constituant la couche interne 7 pourrait être remplacée par une matière non adhésive.To facilitate removal, the label could include a zone which does not adhere to or practically does not adhere to the side wall of the container. This area could be located at a corner of the label in which the material constituting the inner layer 7 could be replaced by a non-adhesive material.
Lorsque l'on souhaite fixer l'étiquette 4 à l'aide d'une machine automatique réalisant le récipient par thermoformage, il est indispensable que les faces opposées de cette étiquette présentent un coefficient de frottement dynamique faible, par exemple de l'ordre de 0,20 à 0,35.When it is desired to attach the label 4 using an automatic machine producing the container by thermoforming, it is essential that the opposite faces of this label have a low dynamic coefficient of friction, for example of the order of 0.20 to 0.35.
Afin de satisfaire cette exigence, la couche externe est de préférence réalisée en un papier couché sur au moins sa face externe et ayant une épaisseur de l'ordre de 80 à 130 g/m2. Elle pourrait toutefois être également constituée par un film de matière plastique et/ou de métal, éventuellement associé à une couche de papier.In order to satisfy this requirement, the outer layer is preferably made of paper coated on at least its outer face and having a thickness of the order of 80 to 130 g / m 2 . However, it could also consist of a plastic and / or metal film, possibly associated with a layer of paper.
Lorsque la couche externe est imprimée, il peut être souhaitable de la protéger contre les agressions extérieures à l'aide d'un vernis transparent glissant.When the outer layer is printed, it may be desirable to protect it from external aggressions using a transparent sliding varnish.
Quant à la couche interne, elle peut être réalisée par un produit thermofusible scellable à une température d'environ 70°C. Un tel produit a l'avantage de ne pas être collant ou poisseux à la température ambiante et de permettre l'utilisation des machines automatiques actuelles de production de récipients par thermoformage.As for the internal layer, it can be produced by a sealable hot-melt product at a temperature of around 70 ° C. Such a product has the advantage of not being sticky or sticky at room temperature and of allowing the use of current automatic machines for producing containers by thermoforming.
A titre d'exemple, on indiquera que le produit thermofusible peut être à base d'un mélange constitué d'un copolymère d'éthylène et d'acétate de vinyle, d'une paraffine et d'une résine poisseuse, et peut-être appliqué à raison de 10 à 15 g/m2.By way of example, it will be indicated that the hot-melt product may be based on a mixture consisting of a copolymer of ethylene and vinyl acetate, of a paraffin and a tacky resin, and can be applied at a rate of 10 to 15 g / m 2 .
En fait, le produit thermofusible utilisé pour réaliser la couche interne est choisi en fonction de la nature du matériau constituant le récipient. Plus précisément, il doit être capable de fondre superficiellement sous l'action de la chaleur de thermoformage de ce matériau.In fact, the hot-melt product used to make the internal layer is chosen according to the nature of the material constituting the container. More specifically, it must be able to melt superficially under the action of the thermoforming heat of this material.
Le pot à yaourt représenté sur la figure 3 est tout à fait classique. On indiquera simplement qu'il est réalisé en matière plastique et qu'il comporte un rebord périphérique entourant son entrée et sur lequel est fixé un opercule plat 9.The yogurt pot shown in Figure 3 is completely conventional. It will simply be indicated that it is made of plastic and that it has a peripheral rim surrounding its entry and on which a flat cover 9 is fixed.
Ce pot comporte une étiquette 10 dont la structure est la même que celle de l'étiquette 4 puisqu'elle est constituée, comme cette dernière, d'une couche externe 11 portant des signes 12 visibles de l'extérieur, d'une couche interne 13 fixée par adhérence sur la paroi latérale du pot, et d'une couche intermédiaire 14 située entre les couches externe 11 et interne 13.This jar has a label 10 whose structure is the same as that of the label 4 since it consists, like the latter, of an outer layer 11 carrying signs 12 visible from the outside, of an inner layer 13 fixed by adhesion to the side wall of the pot, and an intermediate layer 14 located between the outer 11 and inner 13 layers.
Les couches externe 11, interne 13 et intermédiaire 14 peuvent avoir la même constitution et la même épaisseur que les couches correspondantes de l'étiquette 4.The outer layers 11, inner 13 and intermediate 14 can have the same constitution and the same thickness as the corresponding layers of the label 4.
En fait, l'étiquette 11 ne diffère de l'étiquette 4 que par ses dimensions. Alors que l'étiquette 4 ne recouvre qu'une surface limitée de la paroi latérale 1 du récipient, l'étiquette 11 s'étend tout autour de la paroi latérale du pot, ses deux extrémités transversales étant superposées lorsqu'elle est fixée.In fact, the label 11 differs from the label 4 only in its dimensions. While the label 4 covers only a limited surface of the side wall 1 of the container, the label 11 extends all around the side wall of the pot, its two transverse ends being superimposed when it is fixed.
Afin de faciliter la prise de l'étiquette 11 en vue de son arrachement, il est possible de prévoir un vernis anti-adhérent entre les deux côtés transversaux superposés de l'étiquette.To facilitate taking of the label 11 for tearing, it is possible to provide a non-stick varnish between the two overlapping transverse sides of the label.
On notera ici que la couche intermédiaire peut être réalisée lors de la fabrication des étiquettes, par dépôt de la matière qui la constitue entre les couches interne et externe, ou avant la fabrication des étiquettes, par dépôt de cette matière soit sur la couche externe, soit sur la couche interne.It will be noted here that the intermediate layer can be produced during the manufacture of the labels, by deposition of the material which constitutes it between the internal and external layers, or before the manufacture of the labels, by deposition of this material either on the outer layer or on the inner layer.
La couche intermédiaire pourrait également être constituée par une matière incorporée dans la masse de la couche interne ou de la couche externe et ayant migré entre les couches interne et externe. Une telle matière pourrait par exemple être constituée par un érucamide ou un oléamide.The intermediate layer could also consist of a material incorporated into the mass of the internal layer or of the external layer and having migrated between the internal and external layers. Such a material could for example consist of an erucamide or an oleamide.
Grâce à la présente invention, les étiquettes apposées sur des récipients pour produits alimentaires ou autres peuvent être arrachées facilement. Leur arrachement s'effectue au niveau de leur couche intermédiaire, leur couche interne restant fixée sur le récipient. Cette caractéristique permet d'utiliser un matériau ayant un faible coefficient de frottement dynamique pour réaliser la couche interne et de poser des étiquettes telles que les étiquettes 4 et 11 avec une machine automatique réalisant les récipients par thermoformage dans des moules à l'intérieur desquels elle a préalablement introduit les étiquettes.Thanks to the present invention, the labels affixed to containers for food products or the like can be removed easily. They are torn off at their intermediate layer, their internal layer remaining fixed on the container. This characteristic makes it possible to use a material having a low coefficient of dynamic friction to produce the internal layer and to apply labels such as labels 4 and 11 with an automatic machine producing the containers by thermoforming in molds inside which it previously introduced the labels.
