Description

SUMMARY OF THE INVENTION Forms of packaging or packaging auxiliaries with integral guarantee of opening for the first time or of original packing are elaborated from a substrate (10) and a single layer or several layers is applied on the substrate. Examples of substrates (10) are forms of packaging of deep stamping materials or of a sheet material such as, for example, metal sheets, plastic sheets, papers or the like. The substrate has a surface (11) that reflects visible light. On the reflecting surface (11) there is a single or multiple series of layers, comprising one or more layers (12, 14, 16), for example, a compound having the formula SiOx, where x represents a number of 1.5 to 2.0, the thickness of the layer is within a range of 50 to 2000 nm (nanometers), and on top of, the free surface of the SiOx layer is a reflective layer (13, 15, 17) that is semipermeable to visible light and has a thickness of 0.2 to 60 nm (nanometers). The incident light that comes into contact with the coated surface is reflected and the reflected light is observed in different colors according to the direction or angle of observation.

PACKING MATERIAL The present invention relates to packaging forms or packaging auxiliaries having an integral first time and / or original packaging warranty that contain a substrate with a reflecting surface and a process for manufacturing said forms of packaging or packaging. packing auxiliaries It is known to manufacture packaging forms or packaging auxiliaries that are safe against counterfeiting by using holograms, color codes or invisible characteristics. In order to determine if a package has already been opened, either with or without permission, a first opening guarantee is provided on the package itself. This guarantee allows the customer to see if the purchased item has actually been produced and packaged by the desired manufacturer and is not an imitation or counterfeit. The first opening guarantee can, for example, take the form of a label, stamp, or seal band, etc., which is placed, for example, on the lid of a bottle or a wide-necked jar, on the seam joining the lid and a container or on the release fastener in a bag. When opening the package in question, the label, stamp or seal band is broken, which shows that the package has already been opened. It is also possible to transfer or enclose items when packaging again in such a way that - by means of unmistakable characteristics that can not be copied, it is clear which supplier packaged the items in question. In practice, holograms have been used for this purpose. Examples of this situation are hologram labels or cover sheets with integral holograms. Obviously, it is extremely expensive to produce holograms. Due to the fact that forms of packaging and packing auxiliaries are used for products that have a short life that are only used once, efforts are made in the sense of offering packing forms or packing auxiliaries that are economical to manufacture but They are not easy to fake. The objective is achieved by means of the present invention to the extent that, on the reflective surfaces (11) there is a layer or several layers of one or more ceramic layers (12, 14, 16) containing or comprising a compound having the formula SiOx, where x represents a number from 1.5 to 2.0, each layer having a thickness of 50 to 2000 nm (nanometers), and on the surface of the ceramic layer or on at least one of the surfaces of the layers ceramic, a layer (13, 15, 17) that is semipermeable to visible light is provided, said layer is made of metal and has a thickness of 0.2 to 60 nm (nanometers), and is such that the light coming into contact with the coated substrate it is reflected and the reflected light can be seen as different colors depending on the direction or angle of observation. The integral guarantee of opening for the first time and / or origin of the packaging or packaging auxiliaries in accordance with the present invention can always be recognized by the observer under daylight or artificial light, directly and without the aid of any type of device. The color, the color tone observed by the observer depends on the direction or angle at which the package is seen. The substrate used can, for example, be any type of packaging material of choice. The packaging material may be rigid, semi-rigid or flexible, and may be a formed body, or, particularly, a sheet or film material. Examples of shaped bodies are blown bodies, formed by deep and / or stretched stamping, such as bottles, wide neck containers, precipitation basin, plates or base parts of pressure assemblies. Examples of sheet type materials are metal foils of aluminum, steel, copper, silver or gold. Other examples of sheet-like materials are paper, such as tissue paper with a weight per unit area of 20 to 30 g / m2 or highly bleached paper having a weight per unit area of 40 to 60 g / m2, cardboard , semicartón or similar. Especially important are films containing plastic, for example plastic based on polyolefins, polyethylenes or polypropylenes, polyamides, polyvinyl chloride, polyesters, such as for example polyalkylene teredtalates and particularly polyethylene terephthalate. Films that contain plastic can be plastic films, sheets of two or more plastic films, sheets of metal sheets and plastic films, sheets of two or more plastic films, sheets of metal and plastic film, sheets of papers and plastic films or sheets of paper and sheets of metal and plastic films. The individual plastic films can have a thickness of 12 to lOOμm and metal sheets of 12 to lOOμm in thickness. Substrates and also sheets can be, for example, paper, semicarton, cardboard and metal sheets. The individual layers of sheet-like materials can be joined together by means of adhesives, rolling agents, bonding agents and / or by extrusion coating, co-extrusion or lamination, etc. Preferred substrates are biaxially oriented, single or unoriented monolayers or sheets of two or more unoriented, single-oriented or biaxially oriented films based on polyolefins, such as polyethylenes or polypropylenes, polyamides, chloride polyvinyl, polyesters such as polyalkylene terephthalates, and particularly polyethylene terephthalate. For example, mono-films can be provided which act as the basic substrate with the layers according to the present invention and, in subsequent processing steps, the mono-films deposited in additional layers until the final formation of the substrate. Additional typical examples of substrates have the following constitution: a) a first layer containing a unoriented monolayer, uniaxially oriented or biaxially oriented or a sheet of two or more ho oriented, uniaxially oriented or biaxially oriented films based on polyolefins such as for example polyethylenes or polypropylenes, polyamides, polyvinyl chloride, polyesters such as for example polyalkylene terephthalates and particularly polyethylene terephthalate and / or paper such as for example a tissue paper with a weight per unit area of 20 to 30 gm / m2 or a highly bleached paper of 40 to 60 gm / m2, or a protective layer of organic coating, b) a second layer such as a sheet of metal and particularly an aluminum sheet, c) a third layer in the form of a deposited layer of organic heat sealing material; or a) a first layer in accordance with what is described above, b) a second layer, in accordance with what is written above, c) a third layer of unoriented mono-film, oriented monoaxially or biaxially or a film of two or more films not oriented, oriented monoaxially or biaxially of plastics based on polyolefins, such as for example polyethylenes or polyamides, polyvinyl chloride, polyesters such as for example polyalkylene terephthalate, and particularly polyethylene terephthalate or a coating of molten polyethylene; or a) this layer is omitted, b) a first layer, such as for example a metal layer, and in particular an aluminum sheet, c) a second layer containing one or more monoaxially or biaxially oriented monolayers or a sheet of two or more non-oriented, monoaxially oriented or biaxially oriented films of polyolefin-based plastics, such as polyethylenes or polypropylenes, polyamides, polyvinyl chloride, polyesters such as polyalkylene terephthalates and particularly polyethylene terephthalate, and / or a paper such as example paper for tissue with a weight per unit area of 20 to 30 g / m2 or a highly bleached paper having a weight per unit area of 40 to 60 g / m2, or a protective organic coating. As a rule, the first layer a) faces outwards from the package or is itself the side facing towards the outside of the package. Accordingly, the reflecting surface is located on the free surface of layer a) or the free side of layer b) represents the reflecting surface. When using a packaging material available, for example, as a cover material for the purpose of covering transparent containers, such as transparent base parts of blister packs or transparent buckets or the like, a reflecting surface and the series of layers in accordance with the present invention deposited there can be focused towards the internal part of the package and be visible through the transparent container part, precipitate tank or the like. The substrate must present the external surface that reflects the visible light. For this reason, it is necessary that the paper, cardboard or half-film, films or films with external plastic layers have a reflective surface layer. In the case of metal sheets, the reflective layer may be the metal sheet itself. Metal sheets that act as a reflective layer can already present a shiny surface until highly reflective, if said metal sheet is not present in the substrate, or if the metal sheet is integrated between other layers, or if the properties Reflectors of the metal layer are inadequate, then a reflective layer can be deposited, for example, by chemical, wet chemical or physical deposition of a metal. The deposition of the metal can preferably be carried out by means of a thin film deposition process in vacuum such as for example chemical vapor deposition (CVD) or physical vapor deposition (PVD) or by electronic deposition. If the substrate is a material that can be bent, then this coating can be carried out continuously in an inductive treatment process. On the reflecting surface are one or more ceramic layers in the form of a compound having the formula SiO x or containing a compound having the formula SiO x, where x is a number from 1.5 to 2.0, usually a number from 1.5 to 1.9 , and preferably a number from 1.5 to 1.8. such ceramic layers have low refractive indices, preferably with values less than 1.6. the ceramic layers can be obtained by methods such as vacuum film deposition techniques, usually based on electron beam vaporization or resistance heating or inductive heating of the materials to be vaporized, which are known as white or white materials. Preferably the vaporization by electronic rays is used, the described processes can be reactive and / or supported by sputtering. These processes are carried out in such a way that the materials to be vaporized, for example, mixtures of silicon oxide and metallic silicon, are vaporized in vacuum in a vacuum chamber. In the vacuum chamber, a ceramic layer of compounds of the formula SiOx or containing compounds of the formula SiOx is deposited on the entire surface of the substrate and forms the ceramic layer on the substrate side exposed to the vaporized material . The desired value x can be obtained, for example, by adjusting the stoichiometric ratio between Si02 and Si or between Si02 and Si and other additives. The ratio in terms of amounts between the oxygen-containing compound and Si semimetal can, in accordance with the present invention, represent an oxygen deficit of up to 10 to 30% with reference to the pure oxide in the vaporized material. The present invention therefore relates to a process for the manufacture of forms for packaging and / or packaging auxiliaries with an integral guarantee of first opening and / or origin, which contains a substrate with a reflecting surface. According to the process, a thin film deposition process is used in vacuum to deposit on the reflecting surface - simultaneously in vacuum - silicon dioxide (Si02) and the silicon semimetal (Si) as material to be vaporized, at least one ceramic layer 200 nm (nanometer) thick that comprises or contains a compound having the formula SiOx, where x represents a number from 1.5 to 2.0. Subsequently, a reflecting layer of 2.0 to 60 nm (nanometers) of a metal is deposited which is semipermeable to visible light - for example by electron deposition - on the free surface of the ceramic layer. Additional additives, such as for example A1203 B203, and / or MgO can be added to Si02 for vaporization in "amounts of, for example, up to 50 mol%, usually at least 5 mol% and preferably up to 30 mol%, in each case, with reference to the amount of SiO2 Additional materials that can be added for vaporization in SiO2 are materials such as Al, B and / or Mg, in pure form or in an Si alloy, containing Al, B and / or Mg. The additions of Al, B and / or Mg may be in amounts of, for example, up to 50 mol%, usually at least 5 mol%, and preferably up to 30 mol%, in each case with reference to the amount of Si. The quantitative proportions between the oxygen-containing compounds such as Si02, A1203, B203 and MgO and the metals or semimetals are selected, for example, such that in the vaporized material there is a stoichiometric oxygen deficit of 10 to 30% - with reference to the sum of the pure oxides (Si02 and possibly A120, B203, and / or MgO).

The coating process is controlled through the rate of vaporization of the material in the trisol, the rate of deposition in the substrate and the duration during which the substrate is exposed to the atmosphere in the vacuum chamber, and such that deposit a layer of 50 nm (nanometer) ceramic material at 2000 nm thick, usually 100 to 1000 nm thick, preferably 150 to 500 nm thick. These layer thicknesses define the color effect that can be achieved. On all or part of the surface of the first ceramic layer, a second layer or several layers of the aforementioned ceramic materials can be deposited, such as, for example, materials that consist of or contain compounds having the general formula SiOx, each layer having a thickness of the thicknesses provided for the first ceramic layer. In the case of a partial coating, the second layer may have the form of a pattern, such as a logo, a character, a series of lines, etc. Visual effects can be created by reflecting the incident radiation by layers of different thickness. An additional layer of a metal of a thickness of 0.2 to 60 nm (nanometers) usually from 1 to 40 nm and preferably from 2 to 20 nm is provided on the ceramic layer or the ceramic layers. This additional layer reflects the visible light in a semitransparent manner and comprises or contains, for example, one or more of the following metals viz., Stainless steels, Ni, Al, Cu, Ag, Au and preferably Cr. The semitransparent layer of metal it can be deposited using an additional vacuum film deposition process, for example as described above, with one of the aforementioned metals as material to be vaporized or by electronic deposition with one of the aforementioned metals as white. The blank may, for example, be one of the following viz metals, stainless steel, nickel, aluminum, copper, silver, gold, and preferably chromium or mixtures of alloys thereof containing or consisting of the aforementioned metals. In continuous coating processes, the substrate can be coated with the ceramic layer in a first chamber, then passed through a slit-type gate and in an additional chamber where the semitransparent layer of metal is deposited by electronic deposition. In addition, it is also possible to print on a part of the semitransparent metal reflective layer using any color printing material of choice. Printing can be done as an image such as a logo, a character, line patterns, etc., in one or more colors. In order to achieve the effectiveness of the layer system according to the present invention, the printed image can be deposited only on a part of the surface area. A printed image, to characterize the packaging and packaging auxiliaries and protection thereof against forgery, can be deposited directly on the reflective layer of the substrate in another way or additionally. The print may have a shape of an image such as a logo, a character, line patterns, etc., in one or several colors provided the white color is not used. Transparent printing colors and clear organic materials are especially suitable and, as a result of the small amount of pigment or dye, form a transparent or translucent cover. The printed image directly on the reflecting surface preferably using a transparent printing material can be in one or more shades of color and the color tones correspond especially to the colors that are created by the layer system according to the invention when Observe at a particular angle. By observing the packaging or packing aid in the particular angle, the printed image disappears since the color of the image and the color created by the reflection of the light through the different layers is the same. The reflective layer can also be equipped with a logo, character, pattern of lines, etc., by chemical means such as for example engraving and the like. The ceramic layer is then in the printed image or engraved pattern. Before or after depositing the layers, it is also possible to emboss a pattern on a substrate, such as logo, character, pattern of lines, particularly when using a sheet metal substrate, i.e., for example by using of embossing rollers or embossing stamps. Before or after printing in accordance with the present invention, it is also possible, for example, when the substrate has the form of a film, to stretch the substrate in the form of a package, for example, by the use of deep stamping or well-drawn stretch, or a process that combines deep stamping with stretch printing. The embossing process and the stretching process do not influence the color effect, or its influence is very slight, and the color effect is preserved. The aforementioned vacuum thin film deposition processes based on electron beam vaporization and electron deposition can be refined for the purpose of coating the substrates in question. By continuously measuring the reflection spectrum of the coated substrate, and thereby the color of the layer system in the substrate, the power of the electronic beam can be increased or decreased as required to achieve the desired layer thickness or color. The control can be carried out through an automatic control system. In continuous processes, the deposition speed can in some cases be controlled through the substrate advance speed. The process and the choice of the material described for the vaporization or the white material used to create the layers of the aforementioned ceramic materials allow, for example, high yields of 100 m / min while coating substrates in the form of bands, or speeds of coating up to 200 m2 / min. Particularly clear ceramic layers, free of yellowing, are obtained by the appropriate choice of the material for vaporization or white materials and the creation of ceramic layers of the compounds having the general formula SiOx or containing the compounds having the general formula SiOx / where x represents a value between 1.5 and 2.0. the formation of oxygen, which has to be continuously removed in order to maintain the vacuum, is reduced as a result of the fractions of Si, Al, B or Mg in the materials to be vaporized. This entails, overall, at high vaporization rates. The series of layers according to the present invention can finally be covered by a thermal seal layer or protective outer layer or, in particular, with a transparent plastic film or sheet or plastic extrudate, for example, with the object of protecting said series of layers against damage caused by abrasion or the like. Typical films, sheets or extruded products for this purpose contain, for example polyolefins such as polypropylene. The substrate treated in accordance with that described above can form the packaging or packing aid according to the invention. For example, by stamping and sealing, it is possible to manufacture, for example bags, envelopes, wraps, bags, etc., from substrates in the form of a film. Using the methods of deep stamping and / or drawing stamping, the films can be formed into packages such as packaging parts for pressure packings or blister packs, or wide neck containers, cups for saucers, buckets etc. For example, tubes (tubes in foil) or covers for packaging forms can be manufactured from the films, from the substrates containing, for example, cardboard, it is possible to make boxes such as for example folding boxes. It is also possible to use, for example bottles from blown plastics, or preformed packaging as substrates and depositing the series of layers according to the invention on said forms or substrates. Closures, openings, seams between a related base part and lid, etc., may be equipped with a packaging aid according to the invention in the form of a label, sealing strip, stamp, warranty seal or seal of coating. Generally speaking, the aforesaid packaging auxiliaries are in the form of a film and are fixed on the containers in question through an opening and on the adjacent part of the container, for example by means of an adhesive bond, welding, forming Flange or shrinkage, etc. The packaging assistant characterizes the layer structure according to the present invention which protects against counterfeiting. This layer structure, in some cases, includes the additional measurement of a printed or engraved pattern, and shows, for example, an easily recognized identification mark on the typical packaging of the manufacturer. The layer structure results in the desired reflection of the incident light and color shift of the reflected light in accordance with the angle of view. The falsification by photocopying of the packing assistant and use of the photocopy as a guarantee of the original packaging and original manufacturer would be immediate and easily recognizable since the reflection and the displacement of the color would be missing. In order for the packaging assistant, for example, seal band or bell, to be more easily broken by the consumer, it may be convenient to offer auxiliary for breaking such as weak parts, notches or detachment tabs. It is also possible to employ pressure films that are easy to break, such as for example plastic films containing a filler material or films of two plastics with limited compatibility. Other substrates are shrinkable films. Figures 1 to 3 show by way of example, cuts through the layers of a packaging or packing aid according to the invention. In Figure 1 a substrate (10) is shown as for example a plastic sheet having a reflecting surface (11), for example, covered with a layer, for example, an «aluminum layer deposited by electronic deposition. At the top of the reflective layer (11), there is a series of layers comprising 2 layers (12, 16) of a compound having the formula SiOx, where x is a number from 1.5 to 2.0, each layer having a thickness within a range of 50 to 2000 nm (nanometers) and, in the upper part of the free surface layers of SiOx (12,16), a reflective layer of 0.2 to 60 nm thickness (17) of metal that is Semitransparent to electromagnetic radiation in the range of visible light. The layer (16) of a compound having the formula SiOx represents a deposit that is only partially coated in the form of a pattern such as, for example, a line pattern. In a first process step, the layer (12) is deposited on the entire surface and in a second step, parts of the first layer (12) are masked, for example, by depositing by structured steam of oils (as shown in FIG. known from the manufacture of capacitor sheets) or covered by a template, etc., and the second layer (16) is deposited in the form of vapor on it. By removing the cover, the layer (16) is conserved as an image of the spaces between the cover and the first layer (12). Figure 2 shows a substrate (10), for example, a plastic sheet, a reflecting surface (11), for example a reflective layer, for example aluminum produced by electronic deposition. On the reflecting surface (11) there is a series of layers comprising a layer with a thickness of 50 to 2000 nm (nanometer) (12) of a compound having the formula SiOx, where x is number of 1.5 to 2 and, from the top of the free surface of the SiOx layer, there is a layer of 0.2 to 60 nm (nm) ) reflective (13) of metal, which is semi-transparent to electromagnetic radiation within the range of visible light. Figure 3 shows a substrate (10), for example a plastic sheet covered by a reflecting layer, for example, aluminum, as a reflecting surface (11). On the reflecting surface (11) there is a series of layers repeated twice each comprising a layer of 50 to 2000 nm (nanometer) thick (12, 14) of a compound having the formula SiOx, where x is a number from 1.5 to 2.0, and in the upper part of the free surface of the SiOx layers, there is a layer of 0.2 to 60 nm (nanometers) of reflective thickness (13, 15) of metal that is semi-transparent to electromagnetic radiation within the range of visible light. Instead of the sheets mentioned in the examples, it is possible to use any of the other mentioned substrates. If a substrate (10) with a reflective surface (11) is used, then the reflective layer can be omitted. A color printed image and / or several additional layers, for example, a film or extrudate of a transparent material such as, for example, polyethylene or polymers with ethylacrylic acid (EAA) can be deposited on the free side of the semitransparent reflective layer extreme (13, 15, 17). A printed image can be provided directly on the reflecting surface (11) facing the layer (12), said printed image can be made using a clear Organic coating or, particularly, a transparent printing material. The reflecting surface (11) can also be characterized through a embossed or engraved image.
