Abstract

The aim of the invention is to provide a means of more easily distinguishing proprietary articles from pirate copies. To this end, a security label (A, B) with a security feature (13, 13') which is recognisable to the consumer is stuck to the product or its packaging. Said security feature (13, 13') is only given characteristics which are difficult to copy.

Description

Security label with tamper-evident feature

description

Numerous branded products are increasingly imitated by pirated copies. Plagiarism of this kind, often of poor quality, is brought onto the market by sneaking in the brand name and exact replication of the branded product. This harms not only the manufacturer of the branded product, but also the buyer, who obtains an inferior plagiarism instead of the desired branded product.

The aim of the invention is therefore to provide the customer, but also the manufacturer, with an identification feature, on the basis of which he can undoubtedly distinguish a branded product from a pirated copy, and without extensive technical aids and special knowledge, mostly through direct perception of the product.

According to the invention, a security label to be adhered to an object with its underside is proposed with a plurality of layers lying one above the other, at least one of which is designed as a carrier material layer and at least one further one of which

Forms the top of the label visible, printing-technically produced overprint, characterized in that at least one of the layers in at least one partial area of the label at least one by influencing from the outside, in particular by mechanical or / and thermal and / or chemical influencing and / or radiation in a predetermined Has subsequently changeable security feature and / or at least one security feature formed by including or / and omitting a volume of material or / and adding or / and adding solid material to or from at least one of the superimposed layers. Based on the security feature, the product can be clearly identified as a branded product.

A plurality of such security labels are preferably present as a set of labels, namely with at least one security label for sticking on an object or a product, for example a dry cell battery, and a further security label for sticking on an outer packaging or the like for the object.

If the product and the outer packaging each have the same security features, a branded product can be identified as such by the customer comparing the security feature on the product with that of the outer packaging. If the functions or the configurations of the security features match, this suggests a branded product. If the outer packaging is to cover the product to such an extent that a comparison of the security features would not be possible, it is sufficient that only the labels for the outer packaging have a security feature in the label set.

In principle, all products that can be labeled across the surface, such as containers, bottles, and in particular dry cell batteries, are suitable as products. The security labels preferably carry a pressure-sensitive adhesive layer.

Furthermore, the security features can contain additional product information in a coded manner. The security features can be produced by means of printing or stamping technology, such as perforations, partial or flat adhesive cutouts, partial or flat paint cutouts.

Security features that can be changed by the user can include a so-called functional color, such as thermochromic or photo contain chrome lacquers, the mode of action of which may be based on luminescence, such as phosphorescence or fluorescence, metamerism effects or the like. Functional colors of this type will not be suitable for printing the labels over a large area, so that security features of this type are clearly visibly highlighted compared to the normal color printing of the label.

Also suitable for the security features are metallic or mother-of-pearl or other special effect colors, copy protection colors with and without additional photochromism, so-called ghost colors, which "bleed out" when in contact with water, hand-rubbed or erasable rubbish colors or so-called soft coin colors, which are used when rubbing , Etching or scratching can be rubbed off with a piece of money, for example, or hidden information or patterns can then become visible through a change in color. Printed windows or patterns in, under or on one of the supporting layers of the label, such as plastic film layers, in, under or on the label or in a combination at several different or identical locations of the label layer structure are also suitable.

Furthermore, the security features can contain odorous substances, such as aroma substances, fruit esters, perfume oils, fragrance oils or other substances with a noticeable odor that is introduced into the pressure-sensitive adhesive layer or the print or the carrier film layer, either directly as droplets or as a liquid film or as a cavity filled with liquid, a mixture in lacquer, adhesive or label material is also possible, such as embedding in a matrix material, as a solution or microencapsulated.

Security features produced separately from the imprint can be formed by foreign substances, such as an air or gas inclusion, for example in a laminating adhesive layer, which two film layers of the Connects label material with each other. This can be an enclosed liquid or a solid, such as a metal foil, as well as materials, such as wood, which have been completely untypical for adhesive labels. The foreign substance can also have a hologram or a holoprism film or a holoprism paper, such as endless or scattering oiograms, which are inserted between individual layers of the label material during manufacture, or printed on the top label layer and then optionally covered by a subsequent layer of lacquer or lamination .

The security features can be fully developed when the label is printed or can also be changed by time-dependent effects, for example physical, chemical or electrochemical processes taking place after the label has been completed. If the label contains a layer of heat-shrinkable film, the security feature can only achieve its final shape when the label is shrunk onto the product.

The security feature can be permanently visible or only by pulling off a protective cover, such as a protective film, or loosening a perforation. The security feature can also only become visible through heat, light or other external influences, such as rubbing with a finger or a coin, in order to then either remain permanently visible or to change its appearance after a certain time or to disappear completely or partially .

If the security feature contains a thermochromatic color, it can be a thermochromatic color that has a color change from opaque to transparent when the temperature changes from cold to warm or vice versa, i.e. transparent to opaque when the temperature changes from cold to warm, or the color change manifests itself in a temperature-dependent manner or by exposure to light or other external influences such as pressure, Moisture, etc. induced change in hue or color location. The possible temperature interval for a reversible color change can be in the range of the body temperature, around 35 to 40 ° C, so that the color change can take place when touched with the hands.

If a symbol generated with such a thermochromatic color is touched, the heat transfer of the body heat to the security feature or rubbing leads to the color change mentioned. A symbol that is invisible at normal temperature can become visible (envelope transparent to opaque) or become invisible (envelope opaque to transparent). Furthermore, a symbol of the security feature hidden under a completely covering thermochromatic color layer can only become visible in that the thermochromatic layer changes from completely opaque to completely transparent when touched. The thermochromatic color can also respond to artificial heat sources, especially microwaves.

The symbol can be a pure identification symbol or a company logo or a technical symbol, such as the plus or minus sign of a dry cell battery. Examples of thermochromatic colors are the multi-component color systems sold by the Matsui Shikiso Chemical Company, which are based on photochemical interactions in an active solvent or solvent mixture which determines the temperature range of the color change. But it can also be other thermochromic substances, such as double salts of transition metals, such as cobalt, nickel or manganese with an amine, such as hexamethylenetetramine (H ₂ N- (CH ₂ ) 6NH ₂ ). Such double salts discolor with the elimination of water when heated and return to their original color when cooled with the absorption of moisture. Mercury iodide, dinuclear complex salts of mercury iodide and other metal iodides, heavy metal compounds such as lead chromate or ammonium metavanadate are also possible. organic components such as dixanthylene and biantron, as well as dyes or pigments.

If a photochromatic color is used for the security feature, this can also result in a color change under the influence of daylight or artificial light. The color change can run from transparent to colored, as well as a change from one color to another, for example colorless to blue, yellow to green, orange to gray, red to violet or green to blue. This change in color is caused by the UV content of artificial and daylight. The intensity of the envelope depends on the intensity and spectral composition of the UV portion of the artificial and daylight, so that the color varies constantly and visibly when the branded article is exposed to different lighting conditions. Here, too, the photochromatic color can form an identification symbol or a technical symbol (plus sign of the battery), or a company logo, a character or a trademark or the like.

Further color change variants can be created by mixing the photochromatic color with non-photoreactive standard colors, thus creating changing mixed colors. Likewise, the photochromatic color can be added to a laminating varnish connecting several carrier or film layers of the label and so the color appearance of the entire label can vary with changing light conditions.

Examples of such photochromatic colors are the color systems sold by Sicpa Aarberg AG, which are based on photochemical interactions between a color generator and a color developer, which can also be other photochromic substances, such as silver halides, dyes or pigments. The security feature can also be combined from thermochromatic and photochromatic colors and then show the reactions mentioned in some areas. This creates a double security effect. The change in the thermochromatic color occurs preferably in closed rooms, such as by rubbing with a finger, whereas the photochromatic color change under the UV component of daylight with an absorption maximum in the range from 280 to 380 nm light wavelength.

The security feature can also be irreversibly changeable, which contains at least two substances that are spatially close together, but cannot touch, since one of the substances is microencapsulated. If pressure is exerted on such a security feature, the capsule walls burst and both substances can react chemically with one another, for example with a visible color change, for example from transparent to opaque (colored) or with a color change, for example from white to black. Another possibility is the leakage of dye from a preferably opaque microcapsule when it is destroyed, so that the dye is only visible to the naked eye after the leak.

The dye emerging from the microcapsules can initially be visible and then disappear again through a later chemical reaction with environmental substances, or only become visible through a chemical reaction with environmental substances.

A symbol that is already visible can be converted into another, whereby a triangle becomes a circle, a minus sign a plus sign. It can also be a combination of color and symbol changes if a white triangle turns into a black circle. The security labels intended for the product and the outer packaging are preferably produced in one and the same production sequence, so that the layer structure of the respective labels is in principle identical, in which case the features of the labels can be arranged at the same point in the layer sequence, for example in each case protected embedded under the top film layer or between an uppermost and an underlying film layer of the layer sequence. The films are preferably shrinkable plastic films in order to enable the labels to be shrunk onto and around the products.

The labels can contain one or more thermoplastic films or paper layers as a carrier layer, printed or applied as a layer polymer layers which form a film after application and form barriers against migrating solvents between the label layers. Furthermore, such support layers are to be understood to mean vacuum vapor metallizations or dusted metallizations.

If the labels each contain two or three plastic films lying on top of one another, such as heat-shrinkable plastic films, the security feature can be arranged in a protected manner between that film which represents a print carrier layer and an overlying transparent film which represents the outermost layer of the label. In this case, the security feature is preferably printed directly onto one of the foils, for example from below onto the transparent foil lying on top, for example in one operation, with the remaining, unchangeable colors of the imprint.

If the labels only have a transparent plastic film, which is printed from below in reverse printing and optionally has underlying decorative layers, such as a metallization, the feature can be inserted in print or as a piece between the single film and the layers below. The fact that the security feature is arranged under the uppermost or single film in such single or multi-film labels means that the security feature is protected against manipulation or accidental damage.

The security labels can each have one or more identical or different security features.

To produce a set of security labels, each with at least one security label for the product and another for the outer packaging, the security labels of each set can first be produced simultaneously in one and the same production process and releasably leave the production process on a common carrier tape, the sets on the Lay the carrier tape in a row. Then the common carrier tape is separated to separate the first security labels from the second security labels.

If one then uses the separated carrier tape in a labeling device to apply the labels adhering thereon to the products and the other separated carrier tape to apply the labels adhering thereon to the outer packaging, the associated labels come together again when the product is packaged in the outer packaging , so that the customer can carry out the symbol or function comparison between the product and the outer packaging.

The security features can be used in particular in connection with heat-shrinkable adhesive labels for sheathing dry cell batteries, as are known from the applicant's writings with priority of DE 33 22 309, DE 34 30 162 and DE 295 13 170, on the disclosure of which in full Scope is referred to.

The outer packaging can be, for example, a windowed folding box, a blister pack, a card to which the product is attached by means of molded tabs or a banderole, or the like, to which the further security label can be affixed over a large area. A large number of first and / or further security labels A and B, each of which has the same layer structure, adhere in succession to the respective anti-adhesive carrier sheets or tapes 1, 1 '. Each security label A and B has a transparent, heat-shrinkable cover film layer 3, 3 'as the top layer. At least the first security label A is printed on the underside with an unchangeable decorative layer 5, 5 ', for example using solvent-based or radiation-curable lacquers. This decorative layer 5, 5 'is followed on the underside here by a laminating adhesive layer 7, 7', optionally made of radiation-curable lacquer, which can serve as an optical background for the decorative imprint 5, 5 'or / and a barrier to solvents, which is otherwise separated from the layers below penetrate the printing layer 5, 5 'and could make it unsightly. A metallization 9, 9 'is vapor-deposited or dusted onto this barrier or laminating adhesive layer 7, 7', for example made of aluminum, but this can also be omitted. Next, the layer structure is followed by a pressure-sensitive adhesive layer 11, 11 'on the underside, by means of which the security labels A and B adhere to their respective carrier tapes 1, 1' and are to be glued to the product or the outer packaging after detachment.

Both security labels A and B are produced simultaneously on a common carrier tape, which is separated into the individual carrier tapes 1, 1 'after the security labels A and B have been completed.

In each case at least one security protection feature 13, 13 'is embedded in the plane of the imprint 5, 5' between the plastic film layer 3, 3 'and the lamination adhesive layer 7, 7', with a side distance from an edge 4, 4 'of the security label.

The protective feature can also be realized by means of a complete or partial punching 17, 17 'of the label layers, the side can be completely enclosed by the label material or open towards the edge.

Figure 2 shows a further set of security labels A and B with two, here heat-shrinkable plastic film layers, for example made of HPVC, in the layer structure similar to DE 33 22 309. Parts corresponding to the first embodiment are provided with the same reference numbers, increased by the number 100.

Here too, a large number of first and / or further security labels A and B, each with the same layer structure, adhere to the respective anti-adhesive carrier tapes 101, 101 '. Each security label A and B has at the top a transparent, heat-shrinkable cover film layer 103, 103 ', which is glued here to an underlying print layer 105, 105' by means of a lamination adhesive layer 121, 121 '. The printing layer 105, 105 'is printed on an underlying metallization layer 109, 109', which was previously vapor-deposited or sputtered onto an underlying second transparent, heat-shrinkable film layer 123, 123 '. On the underside of the second plastic film layer 123 there is a pressure-sensitive adhesive layer 1 1 1, 1 1 1 ', by means of which the security labels releasably adhere to their carrier tapes 101, 101' and, after detachment thereof, are to be adhered to the product or the outer packaging. The lowest film layer 123 can be replaced by a paper layer. At least one of the layers 103, 103 'and 123, 123' functions as the carrier layer of the label.

Similar to the above embodiment, there is in each case at least one security feature 1 13, 1 13 'in the plane of the printed layer 105, 105'. Both the imprint 105, 105 'and the security features 1 13, 1 13' are visible through the uppermost plastic film 103, 103 ', while the metallization 109, 109' provides an optical background for the security feature 1 13, 1 13 'and the imprint 105, 105 'forms. Missing that Metallization 1 09, 1 09 ', the lower layer 1 23, 1 23' forms the optical background for the print.

As indicated by dashed lines in FIG. 2, the security feature 1 1 3a can cover the label A almost completely or / and can be partially covered by the print 105 from the edge. This applies to all exemplary embodiments.

FIG. 3 shows a further set of security labels A and B, each with three plastic film layers, each heat-shrinkable, such as HPVC, in the layer structure similar to DE 33 22 309. Parts corresponding to the second embodiment are provided with the same reference numbers, again increased by 100.

A large number of first and / or further security labels A and B, each with the same layer structure, adhere to one another on the respective anti-adhesive carrier tapes 201, 201 '. Each security label A and B has at the top a transparent, heat-shrinkable cover film layer 203, 203 ', which adheres by means of a lamination adhesive layer 221, 221' to an underlying print layer 205, 205 ', which previously adheres to an underlying second transparent, heat-shrinkable plastic film layer 231, 231' has been printed. The second plastic film layer 231, 231 'is followed on the underside by a metallization layer 209, 209', and this in turn is followed by a third heat-shrinkable plastic film layer 223, 223 'which, similar to the second embodiment, releasably adheres to the carrier tape 201, 201' by means of a pressure-sensitive adhesive layer 21 1. The metallization layer 209, 209 'can be vapor-deposited or dusted onto the second plastic film layer 231, 231' from below and then connected to the third plastic film layer 223, 223 'by means of a laminating adhesive layer, for example. Alternatively, the metallization layer 209, 209 'can be vapor-deposited or dusted onto the third plastic film layer 223, 223' and then be glued onto the second plastic film layer 231, 231 ', for example with the aid of a laminating adhesive layer. At least one security feature 213, 213 'is located here in the plane of the imprint 5, 5', embedded above and below between the lamination adhesive layer 221 and the second plastic film layer 231.

The layer lying under the imprint or the metallization can also consist of a material other than plastic film or heat-shrinkable plastic film, such as paper.

FIG. 4 schematically shows a section through a cover film layer 303, as a variant of the cover layers of the above three versions, the corresponding reference numbers being increased by 100 again. This can in turn be an approximately heat-shrinkable plastic film. In contrast to the above statements, here a security feature 313 is attached to the top of the cover layer 303, 303 'of the first and second security labels A and B, for example printed on or glued on as a solid. By removing the security feature 313, 313 'from the cover film 303, 303' by hand or by changing the color of the security feature 313, 313 'by the influence of heat or UV radiation or the like, as described at the beginning, an underlying part of the imprint 305, 305 becomes here 'visible.

FIG. 5 shows an embodiment similar to FIG. 4, the corresponding reference numbers being increased by 100 again. Here, the security feature 413, 413 'is covered by a transparent cover layer 433, for example a printed lacquer layer or an additional film layer, which protects the security feature 413, 413'. Alternatively, the cover layer 433, 433 'can be opaque and removable by the user in order to expose the security feature 413, 413' underneath. Here too, as indicated by dashed lines, the security feature 313a, 313a 'can cover approximately the entire area of the label A, B. The security feature of the first adhesive label for the product can also be omitted in all of the above-mentioned designs, in particular if it were invisibly covered by the packaging.

FIG. 6 shows a set of labels A, B, which is similar to FIG. 1, in which the corresponding reference numbers are increased by 400. A fabric layer 51 3, 51 3 ', which is embedded between the laminating adhesive layer 507, 507' and the pressure-sensitive adhesive layer 51 1, 51 1 ', serves as a security feature. The fabric layer 513, 513 'can consist of individual parts, loose flow, or threads woven in a certain way, for example warp threads and / or weft threads arranged at irregular intervals, the special arrangement or pattern or type of fabric of which functions as a security feature. The fabric layer can contain carbon fibers. In order to be able to recognize the fabric layer, the imprint 505, 505 'has recessed windows 505a, 505a' or is glazed, i.e. transparent, applied. It can also be single threads.

FIG. 7 schematically shows the application of a first security label A to a cylindrical battery body 600 of a rechargeable or non-rechargeable dry cell battery. The security label A is placed with its adhesive layer 11 on the circumference of the battery body 600 such that its longitudinal edges 3a, 3a protrude beyond end surfaces 601, 601 of the battery body 600, the stretching direction R of the cover film 3 in particular extending in the circumferential direction of the battery body 600. The additional plastic film layers of versions 2 and 3, which may be underneath, are also stretched in this stretching direction R, although they can also be stretched in a direction transverse to this, albeit to a lesser extent. The security label A is then wrapped around the circumference of the battery body 600 so that end regions 3b, 3b of the security label A overlap one another. The security label A is then shrunk onto the battery body 600 under the influence of heat, so that the longitudinal edges 3a, 3a rest on the end surfaces 601, 601 of the battery body 600 and, if appropriate, additionally adhere to the end surfaces 601, 601 by means of the pressure-sensitive adhesive 11. Due to the overlapping end regions 3b, 3b and the longitudinal edges 3a, 3a resting on the end faces of the battery body, the security label A encapsulates the battery body in a mechanically protective manner and also forms an electrical insulation of the cell and a leakage protection.

The security feature 13 is here in the area of the least shrinkage of the security label A when applied to the battery body 600, namely approximately halfway between the end areas 3b, 3b.

FIG. 8 schematically shows two cylindrical batteries 600 in a common blister packaging 700, in the axial normal section through the batteries 600. Each battery 600 is covered by a security label A, with the security feature 13 on top. The packaging 700 comprises a carrier, for example one Carrier cardboard 712, and a transparent plastic hood 710 covering the batteries 600 together, which holds the batteries 600 between themselves and the carrier 712 in such a way that their security features 13 are held in position from the outside. In addition to the plastic hood 710, a further security label B with a security feature 13 'adheres to the carrier 712.
