Independent claims are included for the following: (a) an article decorated by the above method; (b) a hollow article whose interior surface has been decorated by a method as above.

Description

La présente invention concerne l'application d'un décor sur un article, grâce à un procédé de dépôt par sublimation dans lequel une encre sublimable, portée par un support flexible, est transférée sur une face de l'article au moyen de chaleur et de pression.The present invention relates to the application of a decoration on an article, thanks to a sublimation deposition process in which a sublimable ink, carried by a flexible support, is transferred to one side of the article by means of heat and pressure.

Les brevets européens EP-B1-0451067 et EP-B1-0606189 décrivent des procédés de ce type.European patents EP-B1-0451067 and EP-B1-0606189 describe processes of this type.

La température à laquelle doit être porté le support flexible pour provoquer la sublimation de l'encre est typiquement comprise entre 140 et 250 °C.The temperature to which the flexible support must be brought to cause the sublimation of the ink is typically between 140 and 250 ° C.

Ainsi, seuls sont actuellement décorés par ce procédé des articles réalisés dans des matériaux ayant une résistance thermique suffisante.Thus, only articles currently produced by this process are currently decorated. in materials with sufficient thermal resistance.

Il est toutefois fréquent, dans le domaine du conditionnement, de réaliser des articles tels que des dispositifs de bouchage ou des récipients en polyéthylènetéréphtalate ou en polypropylène.However, it is common in the field of packaging to carry out articles such as closure devices or polyethylene terephthalate containers or polypropylene.

De tels articles ne peuvent être décorés par les procédés de dépôt par sublimation connus, car le chauffage du support flexible nécessaire à la sublimation de l'encre entraínerait des déformations qui leur feraient perdre leur fonctionnalité.Such items cannot be decorated by the deposition processes by known sublimation, because the heating of the flexible support necessary for the sublimation of the ink would cause deformations which would make them lose their functionality.

La présente invention a pour objet un nouveau procédé de dépôt par sublimation permettant de réaliser un décor sur un article, ce procédé étant caractérisé par le fait qu'il comporte les étapes consistant à :

  • disposer au contact d'une face de l'article un support revêtu d'une encre sublimable,
  • chauffer le support à l'aide de moyens de chauffage pour provoquer la sublimation de l'encre et son transfert sur l'article, tout en refroidissant la face opposée de l'article à l'aide de moyens de refroidissement.
The subject of the present invention is a new sublimation deposition process making it possible to produce a decoration on an article, this process being characterized by the fact that it comprises the steps consisting in:
  • placing in contact with one side of the article a support coated with a sublimable ink,
  • heating the support using heating means to cause the sublimation of the ink and its transfer to the article, while cooling the opposite face of the article using cooling means.

Grâce à l'invention, il est possible de décorer des articles réalisés dans des matières plastiques ayant une résistance thermique normalement insuffisante pour pouvoir être décorés par les procédés connus de dépôt par sublimation.Thanks to the invention, it is possible to decorate articles made in plastics with a thermal resistance normally insufficient for be able to be decorated by known sublimation deposition processes.

On peut ainsi décorer des articles en polyéthylènetéréphtalate ou en polypropylène.We can thus decorate articles in polyethylene terephthalate or polypropylene.

On peut encore décorer des articles réalisés dans des thermoplastiques styrèniques (en particulier les polystyrènes dont le polystyrène choc et le polystyrène superchoc, et leurs copolymères, en particulier SAN, ABS, MABS, NAS, ABS/PC) ou les polyacryliques.We can still decorate articles made of thermoplastics styrenics (in particular polystyrenes including impact polystyrene and polystyrene super shock, and their copolymers, in particular SAN, ABS, MABS, NAS, ABS / PC) or polyacrylics.

Il est également possible, grâce au nouveau procédé selon l'invention, de décorer un article creux en appliquant le support sur une face intérieure de l'article, même si ce dernier est de petites dimensions, puisque la face extérieure correspondante de l'article est alors refroidie.It is also possible, thanks to the new method according to the invention, to decorate a hollow article by applying the support on an interior face of the article, even if the latter is small, since the corresponding outer face of the article is then cooled.

Lorsque l'article est réalisé dans une matière plastique transparente, on peut obtenir des effets esthétiques particulièrement intéressants quand le décor est déposé sur sa face intérieure.When the article is made of transparent plastic, it can obtain particularly interesting aesthetic effects when the decoration is placed on its inner face.

Les moyens de chauffage précités peuvent comporter une poche souple dans laquelle est injecté ou insufflé un fluide chaud, liquide ou gazeux, de préférence de l'air chaud comprimé.The aforementioned heating means may include a flexible pocket in which is injected or blown with a hot, liquid or gaseous fluid, preferably air hot compressed.

Cette poche souple peut être facilement insérée à l'intérieur de l'article à l'état dégonflé et servir, une fois gonflée, à plaquer le support sur la face intérieure de l'article et à apporter la chaleur nécessaire à la sublimation de l'encre et à son transfert. Les moyens de chauffage peuvent encore être constitués par un organe de chauffage présentant une surface complémentaire de celle de l'article devant être décorée, porté à une température suffisante pour provoquer la sublimation de l'encre et son transfert sur l'article.This flexible pocket can be easily inserted inside the article to deflated state and serve, once inflated, to press the support on the inside of the article and provide the heat necessary for the sublimation of the ink and its transfer. The heating means can also be constituted by a heating having a surface complementary to that of the article to be decorated, brought to a temperature sufficient to cause sublimation of the ink and its transfer to the article.

La surface extérieure d'un tel organe de chauffage présente avantageusement une certaine déformabilité, de manière à bien épouser la forme de la face intérieure de l'article.The external surface of such a heating member advantageously has a certain deformability, so as to conform to the shape of the inner face of the article.

Les moyens de refroidissement peuvent être constitués par un noyau de refroidissement sur lequel la pièce est engagée lorsque le décor est appliqué sur la face extérieure de l'article.The cooling means can be constituted by a core of cooling on which the part is engaged when the decoration is applied to the face exterior of the item.

Les moyens de refroidissement peuvent comporter, lorsque le décor est appliqué sur la face intérieure de l'article, des moyens de soufflage ou de pulvérisation permettant de diriger sur la face extérieure de l'article un courant d'un fluide de refroidissement, liquide ou gazeux, de préférence de l'air froid.The cooling means may include, when the decor is applied to the inside of the article, blowing or spraying means making it possible to direct a stream of a cooling, liquid or gaseous, preferably cold air.

L'invention a encore pour objet un article décoré au moyen d'un procédé tel que défini plus haut. The subject of the invention is also an article decorated using a method such as as defined above.

L'invention a encore pour objet un article creux comportant sur sa face intérieure un décor obtenu par sublimation d'encre au moyen d'un procédé comprenant les étapes consistant à :

  • disposer au contact d'une face intérieure de l'article un support revêtu d'une encre sublimable,
  • chauffer le support à l'aide de moyens de chauffage pour provoquer la sublimation de l'encre et son transfert sur l'article, tout en refroidissant autant que nécessaire la face opposée de l'article à l'aide de moyens de refroidissement.
The subject of the invention is also a hollow article comprising on its inner face a decoration obtained by sublimation of ink by means of a process comprising the steps consisting in:
  • placing in contact with an interior face of the article a support coated with a sublimable ink,
  • heating the support using heating means to cause the sublimation of the ink and its transfer to the article, while cooling as much as necessary the opposite face of the article using cooling means.

L'invention sera mieux comprise à la lecture de la description détaillée qui va suivre, d'exemples de mise en oeuvre non limitatifs, et à l'examen du dessin annexé sur lequel :

  • la figure 1 est une vue schématique en coupe illustrant une mise en oeuvre du procédé pour décorer la face extérieure d'un article,
  • la figure 2 illustre une mise en oeuvre du procédé pour décorer la face intérieure d'un article creux, et
  • la figure 3 illustre une variante de mise en oeuvre du procédé pour décorer la face intérieure d'un article creux.
The invention will be better understood on reading the detailed description which follows, of nonlimiting examples of implementation, and on examining the appended drawing in which:
  • FIG. 1 is a schematic sectional view illustrating an implementation of the method for decorating the outer face of an article,
  • FIG. 2 illustrates an implementation of the method for decorating the interior face of a hollow article, and
  • FIG. 3 illustrates an alternative implementation of the method for decorating the interior face of a hollow article.

On a représenté, sur la figure 1, un article 10 en matière plastique, constitué par une pièce destinée à être assemblée avec un autre élément, par exemple un bouchon ou un couvercle.There is shown in Figure 1, an article 10 of plastic, consisting of a part intended to be assembled with another element, for example a plug or a lid.

L'article 10 comporte une paroi tubulaire 11 fermée à son extrémité supérieure par une paroi de dessus 12.Article 10 has a tubular wall 11 closed at its upper end by a top wall 12.

Un support flexible 20, constitué par exemple par un tissu, un papier ou un film, revêtu d'une encre sublimable déposée par impression, est disposé au contact de la surface extérieure 13 de l'article 10.A flexible support 20, constituted for example by a fabric, a paper or a film, coated with a sublimable ink deposited by printing, is placed in contact with the outer surface 13 of article 10.

L'article 10 est engagé sur un noyau de refroidissement 30 assurant le refroidissement de sa surface intérieure 14.The article 10 is engaged on a cooling core 30 ensuring the cooling of its internal surface 14.

Dans l'exemple de réalisation décrit, ce noyau de refroidissement 30 est métallique et comporte des conduits intérieurs 31 parcourus par un liquide de refroidissement à une température de 10°C par exemple.In the embodiment described, this cooling core 30 is metallic and has internal conduits 31 through which a liquid of cooling to a temperature of 10 ° C for example.

Pour transférer le décor sur l'article, de l'air chaud est dirigé sur la surface extérieure du support flexible 20 pour porter ce dernier à une température comprise entre 150 et 250 °C, de préférence entre 180 et 220 °C.To transfer the decoration on the article, hot air is directed on the surface outside of the flexible support 20 to bring the latter to a temperature between 150 and 250 ° C, preferably between 180 and 220 ° C.

La présence du noyau de refroidissement 30 permet à l'article 10 de conserver ses dimensions malgré le chauffage du support 20.The presence of the cooling core 30 allows the article 10 to retain its dimensions despite heating of the support 20.

Au terme d'une certaine durée, l'encre portée par le support 20 se sublime et migre sur l'article 10.After a certain period of time, the ink carried by the support 20 sublimes and migrates on article 10.

La profondeur de pénétration de l'encre dans l'article dépend notamment de la durée de chauffage et de la température de chauffage et peut être de l'ordre de 300 µm par exemple.The penetration depth of the ink in the article depends in particular on the heating time and heating temperature and can be of the order of 300 µm per example.

Une fois le transfert de l'encre ainsi réalisé, le support 20 est retiré.Once the ink has thus been transferred, the support 20 is removed.

L'article 10 peut être revêtu d'une couche d'un vernis protecteur compatible avec l'encre sublimable utilisée, par exemple un vernis polyester ou polyuréthanne.Article 10 may be coated with a layer of protective varnish compatible with the sublimable ink used, for example a polyester or polyurethane varnish.

On va maintenant décrire, en référence à la figure 2, la mise en oeuvre du procédé pour décorer la surface intérieure d'un article creux, constitué ici par l'article 10 précité.We will now describe, with reference to FIG. 2, the implementation of the method to decorate the interior surface of a hollow article, constituted here by the aforementioned article 10.

Le support flexible 20 est cette fois disposé au contact de la surface intérieure 14 de l'article 10.The flexible support 20 is this time disposed in contact with the interior surface 14 of article 10.

Une cloche de refroidissement 40, comprenant des conduits intérieurs 41 parcourus par un fluide de refroidissement, par exemple un liquide à la température de 10 °C, est disposée autour de l'article 10, au contact de sa surface extérieure 13.A cooling bell 40, comprising interior conduits 41 traversed by a coolant, for example a liquid at the temperature of 10 ° C, is arranged around the article 10, in contact with its outer surface 13.

Une poche souple 50 est introduite dans l'article 10 à l'état dégonflé et un fluide chaud, constitué ici par de l'air chaud comprimé est insufflé dans cette poche pour provoquer son expansion et plaquer sa paroi contre le support 20.A flexible bag 50 is introduced into article 10 in the deflated state and a fluid hot, consisting here of hot compressed air is blown into this pocket to cause its expansion and press its wall against the support 20.

La poche souple 50 amène le support 20 à une température suffisante pour provoquer la sublimation de l'encre et son transfert sur la surface intérieure 14 de l'article 10.The flexible bag 50 brings the support 20 to a temperature sufficient to cause the sublimation of the ink and its transfer to the interior surface 14 of the article 10.

Une fois le transfert de l'encre effectué, la poche souple 50 peut être dégonflée et extraite de l'article 10.Once the ink has been transferred, the flexible bag 50 can be deflated and from article 10.

L'article 10 est avantageusement réalisé dans une matière plastique transparente, ce qui permet d'obtenir des effets esthétiques intéressants.Article 10 is advantageously made of a transparent plastic, which provides interesting aesthetic effects.

On a représenté, sur la figure 3, un article 10' creux qui présente une forme générale évasée.There is shown in Figure 3, a hollow article 10 'which has a shape general flared.

Dans ce cas, on peut utiliser comme moyen de chauffage un organe de chauffage 50' ayant une surface extérieure dont la forme est complémentaire de celle de la surface intérieure de l'article 10'.In this case, a heating device can be used as the heating means. 50 'having an outer surface whose shape is complementary to that of the surface inside of article 10 '.

La cloche de refroidissement 40' utilisée présente ici une forme adaptée à celle de la surface extérieure de l'article 10'.The cooling bell 40 'used here has a shape adapted to that of the external surface of article 10 '.

La paroi de l'organe de chauffage 50' destinée à venir au contact du support flexible 20 présente avantageusement une certaine déformabilité, de manière à bien épouser la forme de la surface intérieure de l'article 10'.The wall of the heating member 50 'intended to come into contact with the support flexible 20 advantageously has a certain deformability, so that conform to the shape of the interior surface of article 10 '.

On peut utiliser pour réaliser cette paroi un élastomère de silicone par exemple.One can use to make this wall a silicone elastomer for example.

Grâce à l'invention, on peut décorer des articles, notamment des articles qui ne soient pas des textiles, réalisés dans des matières thermoplastiques telles que PET, PP, PS, SAN, ABS, MABS, NAS, ABS/PC ou PMMA, sans craindre de variations dimensionnelles importantes qui feraient perdre aux articles leur fonctionnalité.Thanks to the invention, it is possible to decorate articles, in particular articles which do not are not textiles, made from thermoplastic materials such as PET, PP, PS, SAN, ABS, MABS, NAS, ABS / PC or PMMA, without fear of variations important dimensions that would make the articles lose their functionality.

Bien entendu, l'invention n'est pas limitée aux exemples de réalisation décrits.Of course, the invention is not limited to the embodiments described.

On peut ainsi décorer un article en appliquant un décor sur sa face intérieure ou extérieure par le procédé de sublimation selon l'invention et en appliquant sur sa face opposée un autre décor par un procédé quelconque, autre qu'un procédé de dépôt par sublimation.We can thus decorate an article by applying a decoration on its interior face or exterior by the sublimation process according to the invention and by applying to its face opposite another decoration by any process, other than a deposition process by sublimation.
