Definitions

  • the present invention relates to a method for producing an unalterable decoration on a article, in particular a plug as commonly used to equip containers for perfumes or other cosmetic products.
  • the invention relates to also an article decorated according to this process.
  • the decor can be made up including a logo, trademark, design, or any other inscription or distinctive sign.
  • One of the techniques used for the realization of such a decoration or drawing consists to metallize the plastic part, protecting, in particular with a varnish, the parts which must not be metallized, which varnish is then eventually eliminated.
  • the plastic part which is wants to metallize is obtained by molding two plastic materials, compatible with each other, one of them being metallizable, the other not being not.
  • This technique encounters great practical difficulties in Implementation.
  • it is expensive, in particular as regards the construction of the molds, and the results obtained are not entirely satisfactory, in that it is difficult to obtain clear dividing lines at the junction of the two plastics.
  • it offers little room for maneuver in the choice of decor that can be achieved.
  • a method is described in which the part is formed from a metallizable material, such as ABS (Acrylonitrile Butadiene Styrene), PP (Polypropylene), POM (Polyoxymethylene), or charged polyester.
  • a sheet of a non-material metallizable such as PVC (polyvinyl chloride) or PC (polycarbonate).
  • PVC polyvinyl chloride
  • PC polycarbonate
  • the laser is a special form of digitally controlled marking.
  • the laser marking is particularly advantageous, in particular because of its cleanliness, recyclability of the marked item, inalterability of the inscription, the flexibility it offers, in particular in the choice of decor and its customization, the resolution it allows, and also because of its economic character to implement.
  • the laser allows for a remote decoration, i.e. without putting the object to be decorated in physical contact with a printing member.
  • these objects are achieved by carrying out a method for the realization of a decoration pattern on an article formed from a support made of a thermoplastic material, said process consisting in metallizing all or part of the support by electroplating, so as to form a coating metallic delimiting said decoration pattern, the thermoplastic surface corresponding to said decoration motif, having been the subject of a prior treatment so as not to be metallizable by electroplating, said prior treatment consisting in irradiating the thermoplastic surface of the support corresponding to said decoration motif by means of a laser beam.
  • Electroplating is a technique of metallizing an object, using the conductivity properties of the material forming the object.
  • the materials thermoplastics used are made conductive by a multiple process stages during which the object to be galvanized is dipped in a succession of baths.
  • a first step we create micro roughness on the surface of the object so as to generate anchor points for the deposit metallic. For this, organic bridges of its structure are broken during this step.
  • the butadiene microspheres arranged on the surface of the material are destroyed, thus leaving room for micro-cavities intended to form such points anchor.
  • the protective colloid is removed so as to activate the palladium.
  • the object is made conductive by an operation, called "Chemical nickel plating".
  • Nickel layer typically, a layer of Copper can be deposited on which one deposits a layer of Nickel, Bronze, Chromium or gold.
  • the layer of copper has the function of reinforcing and stiffening the thin deposit of Nickel.
  • the decoration motif can consist of a text, a trademark, a logo, a design, or any other motif.
  • the combinations of contrasts and colors that can be obtained are multiple, simply by playing on the choice of metallic coating, on the choice of the material forming the support, and in particular on its reactivity to laser irradiation, as well as on the choice characteristics of the irradiation.
  • the advantages of the method according to the invention are multiple.
  • the marking is fast (the cycle time, depending on the decor and the room can be around seconds).
  • the resolution of the image produced is of good quality (from the order of a few ⁇ m).
  • it is possible to decorate profile surfaces not planar, or difficult to access, which surfaces would be difficult to access by conventional screen printing or labeling techniques. Marking of the article to be decorated is done remotely, without contact with it.
  • Such a laser decor technology in combination with selective electroplating can be implemented in industrial parts outlet installations, using equipment such as conveyors, robotic arms, rotary tables, or any other means commonly used in the industry industrial.
  • the article to be decorated can be fixed, the laser beam being moved according to the decor to be produced.
  • the laser beam is fixed, the article is moved according to the decoration pattern to be produced.
  • said laser beam is produced by a CO 2 , YAG type laser or an excimer laser.
  • the support can be made of a thermoplastic material such as ABS (Acrylonitrile Butadiene Styrene), PP (polypropylene), POM (polyoxymethylene), a loaded polyamide, or polyester. Any other material can be metallized by electroplating. Materials can be loaded with all types of loads suitable for example to modify their properties physico-chemical.
  • the metallic coating delimiting the decoration pattern is preferably formed superposition of at least two layers of selected metals or alloys especially among chromium, nickel, bronze, silver, gold, zinc, or copper.
  • selected metals or alloys especially among chromium, nickel, bronze, silver, gold, zinc, or copper.
  • an overlay of a layer of nickel is used, copper, and chromium.
  • the material which can be metallized by electroplating is loaded with one or more pigments or dyes so that improve the reactivity to the laser beam of the material forming the support.
  • the material which can be metallized by electroplating is loaded with one or more pigments or dyes so that improve the reactivity to the laser beam of the material forming the support.
  • the material can be loaded by means of pigments, in particular mineral pigments, optionally coated with a layer of chitin or of chitin derivatives.
  • the pigments are chosen from metal oxides, in particular zinc (ZnO), nanotitanes, titanium oxides (TiO 2 ), antimony oxides (Sb 2 O 3 ), mica titanes, calcium carbonates (CaCO 3 ).
  • an article decorated with the process as described above is an article of packaging, in particular a case, a bottle or a jar, or an accessory associated with such a packaging article, in particular a stopper.
  • said article forms a cap for a container intended in particular for packaging a cosmetic product, said cap being formed of a side skirt, in particular cylindrical, one end of which is closed by a transverse wall, said decoration pattern being formed on the wall transverse and / or on the side skirt.
  • the article to be decorated 1 is a plug intended to equip a flask.
  • This plug 1 is formed from a support 2, obtained by molding a galvanizable thermoplastic material such as ABS.
  • the support 2 includes a cylindrical side skirt 3 of circular section, intended to come into engagement with the neck of the bottle.
  • One end of the side skirt 3 is closed by a wall transverse 4 of square section, greater than the section of the side skirt cylindrical 3.
  • the surface of the support 2 corresponding to the decoration pattern to be produced 6 is irradiated by means of a beam 5 generated by a laser 7.
  • the laser 7 is an Nd: YAG laser.
  • the wavelength of laser beam 5 is 1064 nm. Its power is 9 W.
  • the surface to be decorated is about 200mm from the laser, and the focal length is 160 mm.
  • the decoration is more or less visible on the surface of the support.
  • Her color and its contrast vary depending on the reactivity of the material forming the laser irradiation support.
  • the reactivity of the material to the laser beam can be improved by adding pigments or fillers to the material forming the support as previously mentioned.
  • the support 2 thus marked is then caused to pass into a series of baths so as to, by electroplating, cover its non-irradiated surface with coating consisting of a plurality of metallic layers, so as to give at plug 1, as well as at decor 6, their final appearance.
  • the metal coating is formed by an overlay of a layer of Nickel 10, a layer of Copper 11, and a layer of Chrome 12.
  • the thickness of the three layers of metal thus deposited Ni / Cu / Cr can range from 10 ⁇ m to 30 ⁇ m.
  • the surface of the support 2 corresponding to the decoration pattern 6 is as for it, free of any metallic deposit. According to the embodiment which has just been described, the surface corresponding to the decoration pattern 6 is both matt and relatively dark.
  • the metallic coating surrounding it is colored silver, thus achieving sufficient contrast.
