PANNEAU COMPOSITE ET SES APPLICATIONS COMME
ELEMENT DE PROTECTION, DE DEOORAT10N
ETIOU D'IDENTIFICATION
La présente invention concerne un panneau composite et ses applications comme élément de protection, de décoration et/ou d'sdentifi- cation.COMPOSITE PANEL AND ITS APPLICATIONS AS
PROTECTION ELEMENT, DEOORAT10N
IDENTIFICATION LABEL
The present invention relates to a composite panel and its applications as a protection, decoration and / or identification element.
On connaît actuellement de nombreux panneaux composites à base de matières plastiques utilisés comme éléments de protection et de décoration. Numerous composite panels based on plastics used as protective and decorative elements are currently known.
Ces panneaux sont généralement constitués d'un assemblage de feuilles en matière plastique, éventuellement transparentes, prenant en sandwich une feuille prévue pour servir d'élément de décoration; il s'agit le plus souvent de feuilles de papier ou de matières plastiques imprimées. These panels generally consist of an assembly of plastic sheets, possibly transparent, sandwiching a sheet intended to serve as a decorative element; these are most often sheets of paper or printed plastics.
Il faut noter que cet assemblage est réalisé soit par simple solidarisation, par collage ou tout autre moyen, des feuilles de matière plastique sur toute leur périphérie, soit par collage des feuilles extérieures de matière plastique sur la totalité de la surface de la feuille constituant l'élément de décoration. It should be noted that this assembly is carried out either by simple joining, by bonding or any other means, of the sheets of plastic material over their entire periphery, or by bonding of the outer sheets of plastic material over the entire surface of the sheet constituting the decorative element.
La présente invention s'est donné pour objet de fournir un panneau composite permettant la réalisation d'éléments de protection et de décoration qui se distingue des différents panneaux de la technique décrits ci-avant. The object of the present invention is to provide a composite panel allowing the production of protective and decorative elements which differs from the various panels of the technique described above.
Le panneau composite selon l'invention, constitué de l'association de deux feuilles de matière plastique thermo-soudables ou thermocollables prenant en sandwich une feuille comportant un motif de décoration etlou d'identification, est caractérisé en ce que la feuille comportant le motif de décoration et/ou d'identication est munie de perforations la traversant de part en part, en ce qu'elle est réalisée en une matière présentant une aptitude au thermo-soudage et/ou au thermo-collage différente des feuilles extérieures et en ce que l'assemblage des éléments du sandwich est réalisé à travers les perforations traversant la feuille comportant le motif de décoration et/ou d'identification. The composite panel according to the invention, consisting of the association of two sheets of heat-sealable or heat-sealable plastic material sandwiching a sheet comprising a decoration pattern and / or identification, is characterized in that the sheet comprising the pattern of decoration and / or identification is provided with perforations passing right through, in that it is made of a material having an aptitude for thermo-welding and / or thermo-bonding different from the outer sheets and in that the assembly of the sandwich elements is carried out through the perforations passing through the sheet comprising the decoration and / or identification pattern.
Les feuilles de matière plastique constituant les parties extérieures du sandwich sont avantageusement choisies parmi les polymères thermo-plastiques susceptibles d'être réunis par thermo-soudage ou par collage tels que les polyoléfines et plus spécialement le polypropylène et le polyéthylène, le polystyrène, les polyesters et le chlorure de polyvinyle. The plastic sheets constituting the external parts of the sandwich are advantageously chosen from among the thermoplastic polymers capable of being joined together by heat welding or by bonding such as polyolefins and more especially polypropylene and polyethylene, polystyrene, polyesters and polyvinyl chloride.
Selon un mode de réalisation de l'invention, la feuille comportant le motif de décoration et/ou d'identification est choisie parmi les feuilles de papier, de tissu et de métal. According to one embodiment of the invention, the sheet comprising the decoration and / or identification pattern is chosen from sheets of paper, fabric and metal.
Selon un autre mode de réalisation de l'invention, la feuille comportant le motif de décoration et/ou d'identification est une feuille de matière plastique présentant une température de fusion supérieure à celle de la ou des matières plastiques constituant les parties extérieures du sandwich. According to another embodiment of the invention, the sheet comprising the decoration and / or identification pattern is a sheet of plastic material having a melting temperature higher than that of the plastic material (s) constituting the external parts of the sandwich .
Le motif de décoration peut être constitué d'une impression appliquée sur la feuille centrale préalablement à l'assemblage du sand wich ; ce mode de réalisation est tout spécialement adapté au cas où au moins l'une des feuilles extérieures est réalisée en une matière transparente ; cet effet de décoration est renforcé par l'aspect "granité" communiqué au panneau du fait de la solidarisation des feuilles extérieures par l'intermédiaire des perforations ménagées dans la feuille centrale. The decoration pattern can consist of an impression applied to the central sheet prior to the assembly of the sand wich; this embodiment is particularly suitable for the case where at least one of the outer sheets is made of a transparent material; this decorative effect is reinforced by the "granite" appearance communicated to the panel due to the joining of the outer sheets through the perforations made in the central sheet.
II faut noter toutefois que l'on peut également obtenir un effet de décoration très attractif par le seul effet des perforations ménagées dans la feuille centrale, et ceci est spécialement intéressant quand les feuilles extérieures sont réalisées en une matière opaque. It should be noted, however, that one can also obtain a very attractive decorative effect by the sole effect of the perforations formed in the central sheet, and this is particularly advantageous when the outer sheets are made of an opaque material.
Les perforations peuvent, en effet, être ménagées dans la feuille centrale selon un dessin quelconque dont il sera possible de modifier les caractéristiques en faisant varier tant la section que la profondeur desdites perforations. The perforations can, in fact, be made in the central sheet according to any drawing the characteristics of which can be modified by varying both the section and the depth of said perforations.
On obtiendra ainsi un panneau composite présentant un effet de dessin granité très intéressant, susceptible d'être réalisé en petites quantités à un coût et avec des délais nettement inférieurs à ceux réalisés de façon connue qui nécessitent toujours la réalisation et le montage préalable d'un dispositif graineur (généralement un cylindre gravé au motif choisi), alors que pour réaliser le granité de l'invention, il suffit d'utiliser une feuille perforée choisie dans un stock sans avoir à changer les cylindres. A composite panel will thus be obtained having a very attractive granite design effect, capable of being produced in small quantities at a cost and with considerably shorter time periods than those produced in known manner which always require the production and prior assembly of a granulating device (generally a cylinder engraved with the chosen pattern), while to achieve the granita of the invention, it suffices to use a perforated sheet chosen from a stock without having to change the cylinders.
Le panneau composite selon l'invention trouve des applications dans de nombreux domaines ; c'est ainsi qu'il peut être utilisé en papeterie pour la réalisation d'articles de bureau (chemises, classeurs...) ainsi que comme élément d'identification. The composite panel according to the invention finds applications in numerous fields; thus it can be used in stationery for the production of office articles (folders, binders ...) as well as as an identification element.
II convient également bien à la réalisation d'emballages, notam
ment alimentaires, quand les feuilles extérieures sont réalisées à partir
de matières plastiques prévues pour cet usage.It is also well suited for making packaging, in particular
food, when the outer leaves are made from
of plastics intended for this use.
Il est bien évident, par ailleurs, que si les feuilles constituant
les éléments extérieurs du sandwich sont suffisamment épaisses et résis
tantes, le panneau composite selon l'invention peut constituer un élément
de choix pour la réalisation de bagages ; dans ce cas, on utilise, de préfé
rence, des plaques de chlorure de polyvinyle pour la réalisation des élé
ments extérieurs de sandwich et le polypropylène pour la réalisation de
la feuille intermédiaire munie de perforations.It is quite obvious, moreover, that if the leaves constituting
the external elements of the sandwich are sufficiently thick and resistant
aunts, the composite panel according to the invention can constitute an element
of choice for carrying luggage; in this case, we use, preferably
rence, polyvinyl chloride plates for the realization of ele
outer sandwich elements and polypropylene for the realization of
the intermediate sheet provided with perforations.
La présence de ce polypropylène autorise la formation facile
de charnières sur le panneau, ce qui le rend également propre à la réalisa
tion de couvertures de livres.The presence of this polypropylene allows easy formation
of hinges on the panel, which also makes it suitable for the realization
tion of book covers.
Dans une autre application de l'invention, ce panneau est composé
d'une feuille centrale perforée en papier prise en sandwich entre deux
feuilles extérieures de polypropylène, la feuille centrale assurant la fonction
décoration et/ou identification tandis que les feuilles extérieures en polypro
pylène assurent l'effet charnière et la fonction protection, sans nécessiter
de reprise pour impression ou grainage.In another application of the invention, this panel is composed
a perforated central sheet of paper sandwiched between two
outer polypropylene sheets, the central sheet providing the function
decoration and / or identification while the outer polypro sheets
pylene ensure the hinge effect and the protection function, without requiring
recovery for printing or embossing.
La présente invention sera mieux comprise et ses avantages
ressortiront bien de la description qui suit en référence au dessin sché
matique annexé, dans lequel
Figure 1 est une vue en perspective éclatée du panneau compo
site selon l'invention, dans le cas où les feuilles extérieures sont en une
matière plastique thermo-soudable ;
Figure 2 est une vue en coupe transversale du panneau composite
selon l'invention.The present invention will be better understood and its advantages
will emerge well from the description which follows with reference to the dried drawing
attached material, in which
Figure 1 is an exploded perspective view of the component panel
site according to the invention, in the case where the outer sheets are in one
heat-sealable plastic;
Figure 2 is a cross-sectional view of the composite panel
according to the invention.
Sur les figures, le panneau est désigné, de façon générale, par -1, les feuilles de matière plastique thermo-soudable par 2 et par 3, la
feuille intermédiaire par 4 et les perforations par 5.In the figures, the panel is generally designated by -1, the sheets of heat-sealable plastic by 2 and by 3, the
intermediate sheet by 4 and the perforations by 5.
Comme on le voit sur les figures, le panneau composite 1 selon
l'invention est constitué de l'association de deux feuilles de matière plasti
que thermo-soudable 2,3 prenant en sandwich une feuille 4.As seen in the figures, the composite panel 1 according to
the invention consists of the association of two sheets of plastic material
than heat sealable 2,3 sandwiching a sheet 4.
Les feuilles de matière plastique 2,3 constituant les parties exté
rieures du sandwich peuvent être de même nature ou de nature différente.The plastic sheets 2,3 constituting the external parts
sandwiches can be of the same or different nature.
Elles sont avantageusement choisies parmi les polymères thermo-plastiques
susceptibles d'être réunis par thermo-soudage ou par collage tels que
les polyoléfines et, plus spécialement, le polypropylène et le polyéthylène, le polystyrène, les polyesters et le chlorure de polyvinyle.They are advantageously chosen from thermoplastic polymers
likely to be joined by heat welding or by bonding such as
polyolefins and, more particularly, polypropylene and polyethylene, polystyrene, polyesters and polyvinyl chloride.
La feuille 4, prévue pour constituer la partie décorative et/ou d'identification du panneau 1 peut être une feuille de papier, de tissu ou de métal, préalablement revêtue d'un motif décoratif, par exemple par impression. Elle peut être aussi réalisée en une matière plastique présentant une température de fusion supérieure à celle des feuilles 2 et 3. The sheet 4, intended to constitute the decorative and / or identification part of the panel 1 can be a sheet of paper, fabric or metal, previously coated with a decorative pattern, for example by printing. It can also be made of a plastic material having a melting temperature higher than that of sheets 2 and 3.
Selon l'invention, cette feuille 4 est traversée de part et d'autre par des perforations 5 ; c'est par l'intermédiaire de ces perforations que sera assurée la solidarisation des éléments du sandwich. En effet, les résines thermoplastiques constituant les feuilles 2 et 3 assureront, lors de l'opération de thermo-soudage ou de collage, cette solidarisation en passant à travers les perforations 5. According to the invention, this sheet 4 is traversed on either side by perforations 5; it is through these perforations that the joining of the sandwich elements will be ensured. In fact, the thermoplastic resins constituting the sheets 2 and 3 will ensure, during the heat-welding or bonding operation, this joining by passing through the perforations 5.
Il convient toutefois, pour ce faire, que l'aptitude au thermosoudage (ou au collage) des feuilles 2 et 3 soit différente de celle de la feuille 4 munie de perforations 5. However, to do this, the ability to heat seal (or stick) sheets 2 and 3 is different from that of sheet 4 provided with perforations 5.
Ainsi, on peut aussi obtenir un effet granité fort intéressant qu'il est possible de moduler en faisant varier la section et la profondeur des perforations, la profondeur de ces dernières étant liée à l'épaisseur de la feuille 4. Thus, it is also possible to obtain a very interesting granita effect which it is possible to modulate by varying the section and the depth of the perforations, the depth of the latter being linked to the thickness of the sheet 4.
Cet effet granité peut, en lui-même, constituer l'effet décoratif désiré, notamment dans le cas où les feuilles 2 et 3 sont réalisées en un matériau opaque, ainsi que dans le cas où les perforations dont est revêtue la feuille 4 sont réalisées selon un dessin. This granite effect can, in itself, constitute the desired decorative effect, in particular in the case where the sheets 2 and 3 are made of an opaque material, as well as in the case where the perforations with which the sheet 4 is coated are made according to a drawing.
Dans le cas où au moins l'une des feuilles 2 et 3 est réalisée en un matériau transparent, il est possible d'utiliser comme élément central du sandwich une feuille 4 déjà revêtue d'un motif décoratif, par exemple par impression ; l'effet granité obtenu par l'effet des perforations s'ajoutera alors éventuellement à l'effet décoratif du dessin. In the case where at least one of the sheets 2 and 3 is made of a transparent material, it is possible to use as central element of the sandwich a sheet 4 already coated with a decorative pattern, for example by printing; the granita effect obtained by the effect of the perforations will then possibly add to the decorative effect of the design.
