Abstract

A covering or sealing label, comprising a base layer (1) of material which irreversibly deforms or contracts on heating, is new.

Description

The present invention relates to a cover or seal label, the at least one Has base layer.

Cover or seal labels are used in many areas of everyday life these days Found entrance and are used in particular if it applies solving security-relevant and security-sensitive problems. Just think in this connection, for example, to the area of packaging (for Example containers, cardboard boxes, ...), where it is crucial that these remain unopened during storage and transport to avoid the Original condition and completeness of the goods stored in the packaging guarantee. In these cases, the opening or openings of the Packaging attached at least one seal label, so that a unintentional opening or an intended opening of the packaging becomes clear and evident when the seal label is removed or damaged or destroyed, at least no longer in its original, intact condition. Such seal labels are used for unintentional or intended purposes Make manipulations recognizable, and should therefore not least also one have a deterrent effect on people who are unauthorized on packaging Lend a hand, for example to commit theft of goods or to close goods manipulate, for example with a toxic substance.

Cover or seal labels also play a role in other areas important role: This has been the case for many companies for some time of the service industry and / or the manufacturing industry Need to provide information to a customer that should be reserved exclusively for the respective customer and therefore one Protection as safe and reliable as possible against detection by unauthorized third parties Protection as safe and reliable as possible against detection by unauthorized third parties need. Such information can be, for example, the Winning number of a lottery ticket or a secret number for a card, for example for a bank card or for a check card.

In the past, various, more or less practicable ones became available Ways suggested such protection against discovery by to ensure unauthorized third parties:

So the winning number of a lottery ticket was roughly in small, from the respective Customers kept tear-open notes. This was an extensive one Protection against detection by unauthorized third parties guaranteed, but conditional Solution a disproportionate amount of material and processing costs in the Production of the envelopes, so that the manufacturing and processing costs Unfortunately, they were very high.

Due to the fact that in recent years the use of cards for example, increasingly popular in the banking and financial sectors, Naturally, the need for secure and reliable PIN numbers also increases to the respective customer, and only to this one. So it is surprising Not that there are already a number of options for this problem was proposed, but all of them in such a security-relevant Can not completely convince the area like the banking and finance sector. So will For example, discussed the possibility of the card and its associated Secret number separated for security reasons, that is, in two shipping processes to be sent to the customer. This has the advantage that an unauthorized person Recipient of only one of the two programs with this program alone does not do much can begin, but this possibility undesirably implies both higher ones Personnel and higher postage costs. There is also one in this approach to observe increased error rates.

As an alternative to these possibilities, solutions have been found recently proposed a so-called "scratch base":

The information is provided by a base layer and / or by a Covering layer covered or covered, the latter by rubbing and / or by Rubbing is irreversibly removable to cover the covered or covert Make information visible. The ones discussed so far in this context However, proposals are all material-intensive, expensive and cumbersome to handle; sometimes there are significant problems in functionality, that there is a risk, for example, that the relevant information is sent to the Rubbing with your fingernail or with a coin which is of course extremely disadvantageous and especially for security-sensitive people Applications is highly unacceptable.

In this context it can be concluded that the according to the State of the art for the aforementioned purposes disclosed cover or seal labels are very limited in their range of application and for the respective area of application require costly and cumbersome special solutions.

Common to the conventional covering or discussed above Seal labels, however, mainly the problem that these conventional masking or Seal labels due to the effects of heat or heat, for example by means of a Hair dryer or under certain conditions only as a result Sun exposure, can be deactivated in their effect essentially. Is such a cover or seal label, for example by means of a Pressure sensitive adhesive applied to a base, so the adhesive strength of the Pressure sensitive adhesive so far reduced by targeted heat or heat be that the cover or seal label is removable without this externally would be visible; then, for example, by an unauthorized person, without authorization information is obtained or theft or otherwise is inadmissible Manipulation can be made, whereupon the cover or seal label in the undamaged condition back to the original location of the surface can be applied without it being apparent in any form that a Manipulation has taken place. It goes without saying that by the possibility of such, partly criminal, manipulation of immense material and non-material damage can occur.

Given the shortcomings and disadvantages of conventional cover or seal labels is the present invention Task based on a cover or seal label of the type mentioned create that on the one hand material-saving and inexpensive to manufacture and in Within an integrated concept is individually processable and through that on the other hand an effective protection against deactivation by heat or Exposure to heat is required.

This task is solved by a cover or seal label, the at least one Has base layer, the base layer according to the teaching of the present Invention is at least partially in the form of at least one material that becomes irreversible when heated or when the cover or seal label is heated warps or contracts and that the warming or heating of the cover or irreversibly identifies seal labels.

This material is preferably formed in the form of at least one shrink film. Shrink films are cold-stretched, thermoplastic Plastic foils that get back on theirs during heat or heat treatment Contract the original state before stretching. The quest for plastic molecules, too to return to its original tension free arrangement is called elastic shape memory or referred to as memory. In this Context means stretching (stretching) a method of increasing the Strength of filaments and foils; these are in solid state or during the Freeze a train, less often a push, in one direction (so-called "monoaxial stretching" or "uniaxial stretching") or in two directions (so-called "biaxial stretching") exposed, which increases the size up to Ratio of 1:10.

The above solution with which when the cover is heated or heated, or seal labels of irreversibly warping or contracting material implies a number of particularly surprising benefits that are cleverly implemented are combined with each other so that the cover or seal label according to the present invention is also competitive in international markets:

Because of its simplicity, the cover or seal label is material-saving and inexpensive to manufacture. As part of an integrated concept, a user is or enables a processor to process it in just one step to achieve the desired safety and protection effect; nevertheless in individual or the user Solution and design options opened, the main one being effective protection against deactivation by heat or heat or also by steam, by moisture, by acid and / or by environmental influences is required:

If the cover or seal label namely a heat or heat treatment undergoes, the shrink film warps in irreversible, no longer traceable and no longer changeable form, so that a manipulation attempt is clearly marked on the outside. As a result, not just one reapply the cover or seal label in a reliable manner prevented, but also achieved a deterrent in that one Attempt to attempt theft or tampering knows that the theft or the manipulation will be discovered immediately.

In this context, those skilled in the art will particularly appreciate that the Base layer expediently in the form of the heat or heat sensitive material is deformable by stretching and / or by stretching and / or by pulling. Hence the teaching of the present invention is based on a solution principle, on the one hand can be used in a variety of ways and is also independent of the connection of the cover or seal labels with the base works:

Is the base layer of the cover or seal label firmly attached to the base connected, the entire surface is exposed to heat or heat for example by pulling it together with the cover or seal label deformed; the base layer of the cover or seal label, on the other hand, is only loosely included connected to the subsurface, it only shrinks when exposed to heat or heat the material of the base layer, so that only the cover or seal label, not however, the surface is deformed by warping.

As a result, the present cover or seal label can, for example, on the Opening or attached to the openings of a packaging (container, cardboard, ...) be, whereby it is crucial that this packaging during the Storage and transportation remains unopened to the original condition and the To ensure completeness of the goods stored in the packaging. On unintentional opening or an intentional opening of the packaging to the extent that it is clear and evident that the shrink film is formed Base layer with manipulative heat or heat treatment in irreversible, not warped more traceable and no longer changeable form or contracts so that the cover or seal label is no longer in the original is intact condition.

According to an advantageous development of the present invention Base layer transparent. By using a transparent base layer a clear view of the base of the cover or seal label is made possible, For example, on the opening (s) of a packaging that is covered by the cover or Seal label is sealed according to the present invention. That way through the transparent base layer clearly visible at which point the Packaging - properly and legitimately - can be opened. Essentially the same effects can also be achieved by a preferred embodiment who prints the base layer with at least one non-covering color or is colored.

If the present cover or seal label in a particularly inventive manner should be further developed, it is advisable to use the cover or seal label Covering or hiding information. For this purpose, the cover or Seal label preferably covering at least one expediently trained top layer, which as at least one rubbing layer and / or as at least one scratch layer can be formed and accordingly by Rubbing and / or scratching is irreversible to the covered or removable make hidden information visible. This is a cover or In any case, concealment of the information is guaranteed in a reliable manner, a particularly security-related advantage is the fact that due to the Irreversibility of removing the top layer is manipulation by unauthorized persons Third parties are immediately identified.

According to a preferred embodiment of the present invention, it extends the top layer essentially over the entire base layer. This variant enables a particularly simple, inexpensive and quick production of the Cover or seal labels.

Depending on the application and field of application of the present invention however, there are also case constellations in which the possibility is an advantage on the To add other things or symbols in addition to the top layer, such as pictures, serial numbers or the like, so that the Cover layer also essentially exclusively over the part of the base layer can extend in which the information is provided.

According to a particularly inventive development of the present cover or The cover layer at least partially contains at least one pressure sensitive adhesive. This opens up the possibility of placing at least one object on the Attach cover or seal label, this item with the covered or related information. Not only, but also in In this case it is advantageous if the pressure sensitive adhesive can be removed. Through this Property of the pressure sensitive adhesive can be avoided when detaching the object from the cover or seal label, adhesive residues remain on the object.

This is the case according to an expedient embodiment of the present invention for example, a card, such as a card, on the cover or seal label "BahnCard", a bank card, a health insurance card, a credit card, one Customer card, a cell phone card, a check card, a "smart card" or one Telephone card to be attached to a document, such as at least one Letterhead, a customer is sent, which is the card sent Secret number belonging as covered or hidden information under the Cover or seal label can be and where the customer is covered or hidden information by removing the cover layer by rubbing or Rubbing can make it irreversibly visible.

The expert will appreciate in this context that at Do not rub or rub off the top layer as with known scratch-off films accumulating unpleasant waste are released because of binding effects by means of the pressure sensitive adhesive contained in the cover layer occur.

According to an advantageous embodiment of the present invention, the Cover layer at least partially by at least one opaque colored Pressure sensitive adhesive formed, on the one hand a gapless covering or concealment of the Guaranteed information and on the other hand the problem-free if desired Allows detachment of an object on the cover or seal label may be appropriate. In the latter case, the pressure sensitive adhesive is used in practice expediently be such that the object of the covering or Seal label can be removed without leaving adhesive residue on the item remain.

In an alternative, also preferred embodiment of the present Invention, the cover layer has at least one on the base layer at least partially arranged pressure-sensitive adhesive layer and at least one on the pressure-sensitive adhesive layer covering layer of paint arranged at least in places, preferably by Printing is applied and for example at least partially by at least a suitably dark, preferably black flexographic printing ink is formed. In this case it is provided that the opaque color layer, for example by a Fingernail or by a coin that is rubbed or rubbed off to underneath to make the information on the cover or seal label visible, whereby it proves to be expedient if the pressure-sensitive adhesive layer is transparent.

There is a design variant of the cover or seal label according to the present invention, in which the covering color layer has a smaller area than the pressure sensitive adhesive layer occupies, which can mean that the Pressure sensitive adhesive layer is exposed in places, so this design variant is for one Application of the cover or seal label is predestined, in which on the cover or seal label a card, such as a "BahnCard", a bank card, a Health insurance card, credit card, customer card, one A mobile phone card, a check card, a "smart card" or a telephone card, is attached, which on a document, such as at least one letterhead, the Customer is transmitted, the belonging to the transmitted card Secret number as covered or covert information under the cover or Seal label is located and the customer is the covered or covert information irreversible by removing the cover layer by rubbing or rubbing can make visible.

In an alternative embodiment of the present invention, the Cover layer at least one at least partially arranged on the base layer Pressure-sensitive adhesive layer and at least one on the pressure-sensitive adhesive layer at least in places arranged opaque colored adhesive layer. Also in this It is provided that the opaque colored adhesive layer, for example by a Fingernail or by a coin that is rubbed or rubbed off to underneath to make the information on the cover or seal label visible, whereby it proves to be expedient if at least partially on the base layer arranged pressure-sensitive adhesive layer is transparent.

This embodiment is also for an application of the cover or seal label predestined for a card, such as one, on the cover or seal label "BahnCard", a bank card, a health insurance card, a credit card, one Customer card, a cell phone card, a check card, a "smart card" or one Telephone card, is attached to a document, such as at least one Letterhead, which is sent to the customer, referring to the card sent Secret number belonging as covered or hidden information under the There is a cover or seal label and the customer has the covered or covered Information by removing the cover layer by rubbing or rubbing can make it irreversibly visible.

Regarding the cover or seal label according to the present invention in particularly security-sensitive applications, the - at least theoretical - Possibility of an unauthorized person rubbing or rubbing the top layer Removed scratches, takes note of the information underneath and then this information again by applying a new top coat covers or conceals. An existing cover layer is therefore not necessary a guarantee for the original condition of the top layer. Accordingly, according to one particularly inventive further development of the present cover or seal label at least one authenticity feature is provided on the cover layer, whereby the Authenticity or the original state of irreversible by rubbing or rubbing removable cover layer is recognizable by just looking, because when Removing the cover layer will damage or destroy this authenticity feature that is immediately and immediately visible, whether on the top layer beforehand hand was illegally applied.

In order to prevent even the most skilful manipulations, this can be done on the Authenticity feature on top layer on the underlying base layer be continued. The part of the authenticity feature lying on the base layer cannot be removed by rubbing or rubbing. Even if that Top layer is applied again after removal, is by the on the Base layer remaining fragment of the authenticity feature can clearly be seen that it is not the original top layer, because it is true to the original Restoring the removed part of the authenticity feature is practical impossible. According to an advantageous embodiment of the present invention The authenticity feature therefore extends over at least part of the Base layer and over at least part of the top layer.

Depending on the specific design of the authenticity feature, it is from special advantage to print or glue the authenticity feature or with to stamp on at least one hot stamping foil (this hot stamping foil can, for example have a hologram as an authenticity feature) or preferably in the cover layer embossed in relief. According to further alternative or complementary advantageous embodiments of the present invention is accordingly Authenticity feature printed or glued or with at least one Hot stamping foil stamped or stamped into the top layer.

When designing the authenticity feature, for example, picture elements and / or holograms and / or patterns and / or lettering are used. Often it is also advantageous to color the authenticity features in one color (e.g. red, black, white, ...) or multi-colored, especially when aesthetics are particularly important is placed. According to further advantageous refinements of the present invention the authenticity feature therefore has at least one image element and / or at least a hologram and / or at least one pattern and / or at least one lettering on. Independent of this or in connection with this, the authenticity feature can be single color or multicolor.

Forming the cover or seal label according to the present invention in particularly advantageously further, so the cover or seal label at least partially at least one layer of adhesive, the adhesive expediently on the side of the base layer facing away from the cover layer is provided. This adhesive layer serves to attach the cover or Seal labels, for example, on a surface provided for this purpose, for example on a To enable document, for example in the form of at least one letterhead. According to a further alternative or additional advantageous variant, the Adhesive arranged in several places that do not overlap the information.

If the information to be covered by the cover or seal label is below the cover or seal label, it will prove to be useful Adhesive not covering, but only colored or even better to choose transparently. According to this expedient embodiment of the In the present invention, the adhesive is transparent, which is precisely what that the adhesive is arranged flat on the preferably transparent base layer that makes the underlying information visible. For this reason, is after a further advantageous development of the adhesive flat on the base layer arranged, and the information is covered by the adhesive.

If one compares the adhesive strength of the adhesive with the adhesive force of the pressure sensitive adhesive, then the adhesive strength of the adhesive expediently greater than the adhesive force of the Pressure sensitive adhesive, thus a stable and reliable attachment of the cover pad Seal labels on the pad is guaranteed. In this context, the Adhesive, for example, an adhesive that can be activated by water, or an adhesive Be (permanent) pressure sensitive adhesive, with the use of a (permanent) pressure sensitive adhesive as an adhesive it is guaranteed that manipulative detachment attempts fail and close an immediately recognizable damage or even destruction of the cover or Sealing labels and / or the substrate carrying the covering or sealing label to lead.

• mindestens einen ersten Bereich, in dem die Grundschicht auf ihrer Unterseite zumindest partiell mit dem Klebstoff beschichtet ist, und
• mindestens einen zweiten Bereich, in dem die Grundschicht nichtklebend ist, aufweist und daß der zweite Bereich vom ersten Bereich abtrennbar ist, um abgedeckte oder verdeckte Informationen sichtbar zu machen. Auf diese Weise wird eine Abdeckung oder Verdeckung der Informationen in jedem Falle auf sichere und zuverlässige Weise gewährleistet, wobei ein besonders sicherheitsrelevanter Vorteil darin zu sehen ist, daß aufgrund der Irreversibilität des Entfernens des zweiten Bereichs der Grundschicht eine Manipulation durch unbefugte Dritte unmittelbar kenntlich gemacht wird; im Ergebnis kann also nur eine befugte Person, beispielsweise ein Kunde, die abgedeckten oder verdeckten Informationen durch Entfernen des zweiten Bereichs der Grundschicht irreversibel sichtbar machen.

If a particularly secure and reliable covering or concealment of the information is to be ensured, in such a way that making the information visible once leads to an easily recognizable irreversible change, this can be achieved in accordance with a particularly inventive further development of the present cover or seal label, that the base layer

• at least a first area in which the base layer is at least partially coated with the adhesive on its underside, and
• has at least one second area in which the base layer is non-adhesive, and that the second area can be separated from the first area in order to make covered or hidden information visible. In this way, coverage or concealment of the information is guaranteed in a safe and reliable manner, with a particularly security-related advantage being the fact that manipulation by unauthorized third parties is immediately identified due to the irreversibility of the removal of the second area of the base layer ; as a result, only an authorized person, for example a customer, can make the covered or hidden information irreversibly visible by removing the second area of the base layer.

It has proven to be advantageous if the second area starts from the first area is surrounded on at least two sides or - even more advantageously - on three sides. As a result, the first, that is, the non-adhesive area, the immediately Information covered, sealed all around by the second adhesive area, so that it is impossible to go unnoticed and unauthorized to the covered or to get hidden information.

Only at one point should the second area not be from the first area be enclosed in order to grab and tear off the first area at this point can. However, this point should be as narrow as possible in order to to prevent manipulative access to the information. It is preferred hence the second area at this point as at least one handle tab formed, which extends beyond the edge line of the first region.

From the point of view of manufacturing technology, one embodiment has proven to be proven advantageous in which the coating with adhesive in the second Area extends into or where the coating with adhesive even is applied continuously to the entire underside of the base layer, in which however, the adhesive force of the adhesive coating in the second area Cover with a non-adhesive layer is removed. Often Process-technically complex partial adhesive application can be done in this way be circumvented. As the layer that removes the adhesive force, for example at least one cover film, at least one preferably opaque printing ink or at least one varnish can also be used.

However, it is also possible to apply partial adhesive only in the first Area of the base layer the second area of the base layer on the underside of the To keep cover or seal labels (almost) completely free of adhesive, which leads to a Saving material compared to the previously described embodiment leads.

The first area of the base layer is according to an advantageous embodiment by at least one perforation punch from the second area of the base layer Cut. The non-adhesive second region of the base layer can thus pass through Separation of the perforation line can be easily separated; after that can the cover or seal label according to the present invention, however, no longer in the original state can be restored.

According to a particularly inventive development, the base layer is transparent and at least in the second area with an opaque ink on the top or printed on the underside of the base layer. However, it is also possible to use opaque Use material in the manufacture of the base layer.

According to a particularly advantageous development of the present invention the base layer expediently has at least one in its first region Perforation and / or at least one embossing and / or at least one punch on in the form of at least one safety perforation and / or in the form at least one security embossing and / or in the form of at least one Security punching can be formed and preferably essentially can be wavy. By such perforation and / or embossing and / or punching can be prevented that an unauthorized third party or remove the seal label from the surface and then put it back on the Can apply underground in order to manipulate packaging in this way, to commit theft, to cover up a "broken seal" or not to know information intended for him to arrive. The unauthorized third party undertakes namely, such an attempt, this attempt will inevitably result in irreversibly identified that the base layer through the perforation and / or embossing and / or punching expediently into several separate ones Is divided into segments after the cover or seal label has been removed can no longer be applied to the surface in a corresponding manner can.

Around an object, such as a card, on the cover or seal label To be able to attach, it is provided according to an advantageous embodiment that the top of the base layer at least partially at least one more, for example, has a transparent adhesive layer. In this context it is advantageous if the further adhesive layer has at least one removable pressure sensitive adhesive or if the further adhesive layer is at least one removable pressure sensitive adhesive acts so that a detachment of the object without increased Force is possible. The removable pressure sensitive adhesive is advantageously so chosen that none when removing the object from the cover or seal label Adhesive residues remain on the object.

If you compare the adhesive effect of the additional adhesive layer with the adhesive effect of the adhesive, the adhesive strength of the further adhesive layer is expedient less than the adhesive force of the adhesive, thus a stable and reliable Fastening of the cover or seal label on the base is also guaranteed is when the item is removed from the cover or seal label.

The general rule is that the design of the cover layer and the choice of material for the Cover layer according to the intended use of the cover or seal label judge according to the present invention. So according to a preferred one Embodiment of the cover layer by at least one applied to the base layer Color layer formed; regardless of this or in connection with this, the Cover layer to be printed on the base layer. Alternatively, the Top layer also by at least one brittle material layer or by at least a hot stamping foil may be formed.

According to a particularly inventive development of the present cover or The base layer has seal labels on the side facing away from the cover layer at least one sealing area that contains a coating that after Attaching the cover or seal label to an object separating the Indicates base layer of the object irreversibly. As a result, on the one hand increased security against targeted manipulations and others inevitably have a "broken seal". Through this optional technical Measure is therefore guaranteed that the information to be hidden can only be covered by a "broken seal" become accessible, which at least not with normal effort more can be undone or covered up. In this context a particularly high degree of functionality can be achieved if the coating on the Base layer in a substantially corresponding to the sealing area Form is arranged.

According to an advantageous embodiment of the present invention provided that the arrangement of the on the side facing away from the cover layer Base layer arranged adhesive essentially the shape of the Sealing area corresponds. Before using the cover or seal label can this layer of adhesive with at least one adhesive repellent Protective film to be protected. According to an alternative embodiment variant, this can Layer of adhesive may also be arranged on the object on which the covering or Seal label is to be attached.

All types of (permanent) pressure sensitive adhesives are particularly suitable as adhesives, because these do not require any additional activation, apart from the fact that at least a protective paper has to be removed. However, the use of a is also advantageous Water activatable adhesive.

The coating to indicate a first opening of the cover or According to a particularly inventive embodiment, the sealing label has at least one color layer, preferably applied by printing, which with with a first adhesive force on the object and with a second adhesive force the base layer adheres when the cover or seal label is on the item is appropriate. Adhesive force adjusting means are also provided, which Relationship between the first adhesive force and the second adhesive force locally set differently.

If the base layer is separated from the object, the color layer remains partially the base layer and partly hang on the object. This creates one irreversible optical change of the cover or seal label. Even if after separating the base layer, this is glued back onto the object, the color layer has other reflective properties because between the Color layer and the object or between the color layer and the base layer Air has entered, which irreversible and the optical impression of the color layer clearly changed.

In this context, the use of at least one transparent one is advantageous Shrink wrap as a base layer, preferably with a non-opaque bright Color is printed or colored. In such a case, there is a special one clear contrast between the different areas of the color layer when the glued together after the first separation.

A particularly clearly recognizable contrast effect also results when the Color layer an opaque and / or a dark, preferably black color having. A preferred embodiment also serves the same purposes, where the color of the color layer is in contrast to the color of the base layer.

The identification of the opening of the cover or Seal labels become particularly clear when, according to another, particularly advantageous embodiment as a base layer deformable by stretching Shrink wrap is used: To remove the base layer from the object, must a force is necessarily exerted on the base layer; the The base layer is permanently deformed so that when the base layer is glued back the separated parts of the color layer no longer fit together geometrically exactly, which shows the opening in a particularly striking manner. Hereby meets the cover or seal label according to the teachings of the present invention its protective function also regardless of an intended or manipulative Warming or heating.

A particularly advantageous embodiment of the cover or seal label according to the invention is present when the adhesive force setting means at least one partial treatment of the object and / or the base layer include. So the base layer can be printed before printing be subjected to ensure that the printing ink intensely with the Base layer connects and thus a durable print image is generated. Become certain areas of the base layer of the cover or seal label from the Pretreatment of printing, for example, by covering it up, then adheres there applied layer of paint poorly, and with a separation of object and Base layer, the paint layer will stick to that of the two parts, the has undergone print pre-treatment. This way, with the simplest of means the desired color layer separation effect is achieved when the base layer is removed become.

As an alternative or in addition to this, the adhesive force setting means can at least an adhesion promoter applied at least in places (= so-called "primer") include. Such an adhesion promoter who has a particularly intimate connection between the printing ink and the background can be easily done by printing be upset.

Again, alternatively or additionally, the use of at least one non-stick varnish applied at least in places as an adhesive force adjusting agent be beneficial. In particular, the non-stick varnish can be in the form of at least one pattern or be printed in the form of at least one lettering, so that a special Image, such as the word "OPEN", when separating object and Base layer becomes visible.

It is crucial for all types of adhesive force setting means that this Ratio of the respective forces with which the paint layer on the base layer on the one hand and on the top layer on the other hand, influence in such a way, that at least in places the adhesive force on one of the two parts is greater than other of the two parts is. This will separate the two parts Color layer divided according to a certain pattern, that is part of the Color layer remains on the base layer and the other part of the color layer remains on the top layer. The adhesive coating ensures this Relationship to the fact that the color layer with a precisely adjustable force on adhesive-coated area adheres.

The coating presented can be either on the object or on the Base layer may be provided.

If the adhesive force setting means at least in places at least in shape a preferably fine pattern of lines, dots or the like is provided are, even with a very small geometric position deviation between the both parts after gluing back the base layer a structure and / or Color change clearly visible.

The cover or seal label is advantageously on at least one side provided with at least one print, which is at least partially on the Base layer can be arranged and for example an instruction manual may contain. However, the print can also have complicated geometric figures or contain coats of arms, which in turn are not easily imitated and on them Vouch for originality. In any case, it is advantageous if the print is protected or sealed with at least one laminate layer; alternatively or in In addition, the print can be covered with at least one contrast layer his.

As already mentioned, it turns out in the manufacture and in the Further processing of the cover or seal label as an embodiment advantageous in the case of the base layer when heating or when Heating the cover or seal label irreversibly warping or contracting material. With regard to the choice of materials for the The base layer is plastic and in particular cold stretched plastic film deemed recommended, the plastic being preferred thermoplastic, for example polyamide (PA), polyacrylonitrile (PAN) to polycarbonate (PC), to polyethylene (PE), to polyethylene terephthalate (PETP) to polypropylene (PP), to polystyrene (PS) and / or to polyvinyl chloride (PVC), can act.

As already stated above, the cover or seal label plays according to the present invention an important especially in security-sensitive applications Role. So it can be extremely useful if the base layer passes through at least one security material with low tear strength is formed because thereby an unauthorized person from unauthorized removal of the cover or Sealing labels, for example to manipulate packaging, around one Committing theft to cover up a "broken seal" or not to know information intended for the unauthorized person can be. If the unauthorized person has tried to cover or Unauthorized removal of the seal label will be attempted when using a Security material with low tear resistance for the base layer in everyone Trap identified by tearing the base layer in an irreversible manner is. In practice, such a security material is, for example, as at least a cast film is formed.

In connection with questions of the choice of material in the case of covering or Seal label, the pressure sensitive adhesive can be formed by at least one acrylate adhesive.

In addition to providing the shrink film as a base layer, the covering or Seal label according to a particularly advantageous development of the present Invention, at least in partial areas, at least one further temperature indicator on, the heating or heating of the cover or seal label irreversible identifies by heating or on heating the cover or Seal labels appeals irreversibly.

It is of increasing importance that the further temperature indicator is safe and reliably indicates an attempted intervention or manipulation in the case that the effect, for example, of the further pressure-sensitive adhesive layer with which the Base layer at least partially on the side facing away from the cover layer is coated, is deactivated by heating the cover or seal label or is heated. This is the - first time - manipulation of the cover or Seal labels immediately and easily based on the discoloration of the other Temperature indicator recognizable with which at least one side of the cover or Seal label is provided at least in some areas.

In addition to the mandatory shrinkage effect of the base layer, this also occurs Interventions and manipulations in the form of heating or in the form of heating the Cover or seal labels discolored when peeled or opened further temperature indicator on the one hand, irreversible, that is, not which is more reversible and which also can be Reseal the cover or seal label clearly and unmistakably indicates that the cover or seal label has already been used at least once was treated manipulatively.

According to a practical development of the cover or seal label is the further temperature indicator in the form of at least one strip on the cover or seal label arranged. As a result, interventions and manipulations in Form of heating or in the form of heating only parts of the Cover or seal labels can be verified safely and reliably.

The use of a transparent additional temperature indicator is, for example then of decisive advantage if the provision of the further Temperature indicator should not be visible to the naked eye, that is, if the one who undesirably manipulatively manipulates the cover or seal label Wants to treat form of heating or in the form of heating, may not know or is that another temperature indicator is arranged on the cover or seal label is. In this case, the manipulator is or heat inevitable discoloration of the transparent surely another temperature indicator surely surprised.

According to a particularly preferred embodiment, the other Temperature indicator formed by thermoreactive or: thermosensitive paper, for example when heating or heating the cover or seal label shows an at least in places black coloration, which expediently is irreversible.

The cover or seal label according to the present invention can at least contain a luminescent substance. This has an advantageous effect, for example, if in the context of an optical control system for a dispensing device for Cover or seal labels according to the present invention the presence or Absence of a cover or seal label, for example using a camera should be determined.

For a practical and easy to handle further processing and use of the To enable cover or seal labels, the cover or seal label can be used be arranged at least one carrier film, which expediently at least on the side facing the cover or seal label at least one adhesive-repellent smooth layer, for example at least one silicone layer, having.

As already indicated above, the information can be on a document are located, which can be formed for example by at least one letterhead for example, at least one barcode, at least one code word, at least one Secret number, at least one secret number, at least one customer number, at least one personal identification number (PIN = Personal Identification Number) and / or at least one barcode as by the cover or seal label information to be concealed is plotted.

According to a particularly inventive development, the covering or Seal label associated with at least one sheet or card-shaped object his. As already indicated, alternatively or in addition to this the pressure sensitive adhesive removably attached at least one object, the Pressure sensitive adhesive is advantageously matched to the object so that the Pressure sensitive adhesive can be removed from the object without leaving any residue. This item can be at least one card, for example a "BahnCard", a bank card, a Health insurance card, credit card, customer card, one Mobile phone card, a check card, a "smart card" or a phone card.

The same or similar components or features of the present invention are shown in Figures 1 to 18 provided with identical reference numerals.

FIG. 1 shows a cover or seal label applied to a packaging in shown from above. Here is the cover or seal label on the in Figure 1 provided slot-like opening of the approximately cuboid Cardboard packaging attached, it is crucial that this Packaging remains unopened during storage and transportation to the Original condition and completeness of the goods stored in the packaging guarantee.

A manipulative opening of the packaging is now clear and evident in that as the base layer 1 of the cover or seal label as a shrink film (thermoplastic plastic film) is formed and this shrink film Heat or heat treatment in irreversible, no longer traceable and not more changeable shape contracts, so that the cover shown in Figure 1 or the seal label is then no longer in its original, intact condition; the Attempted manipulation is then clearly identified on the outside.

As a result, it is not only possible to reapply the cover or seal label from Figure 1 can be prevented in a reliable manner, but a deterrent Effect can also be achieved in that a theft or Manipulation attempt knows that the theft or the Manipulation due to the shrunk condition of the warped cover or Seal labels will be discovered immediately. Here is the shrink wrap trained base layer 1 of the cover or seal label firmly with the base, that is connected to the top of the packaging, so that when heat or Heat also affects the area of the slit-shaped opening at the top of the Packaging deformed by pulling it together with the cover or seal label and is irreversibly affected.

A further exemplary embodiment of a shown in a sectional view in FIG Cover or seal labels has a base layer 1, which consists of a transparent Shrink wrap exists. On the top of the base layer 1 there is a cover layer 2 arranged, which essentially consists of a colored with an opaque color There is pressure sensitive adhesive. The pressure sensitive adhesive is a pressure sensitive adhesive with relative low adhesive strength, which is commonly referred to as "removable pressure sensitive adhesive". On the underside of the base layer 1 is another transparent pressure-sensitive adhesive layer 6 provided with the cover or seal label if desired on a Item or document can be attached. The attachment with others Means, such as with glue, with sealing wax or by stapling, is also possible.

The cover or seal label according to FIG. 2 is particularly suitable, certain Positions that contain secret key figures, for example, in a document to cover. Since the opaque colored pressure sensitive adhesive is a removable pressure sensitive adhesive, can this easily with a hard object, such as a coin, rubbed off or "rubbed off", thereby clearing the view. It has shown that when rubbing off the opaque colored adhesive layer is not the in the case of known scratch-off films, unpleasant color waste is released, because the color is bound by the removable adhesive. The Cover or seal label is also thanks to its adhesive top layer 2 suitable as a fastener for a small object, such as a Coin or check card to serve. The cover or seal label can thus conveniently when sending credit cards with simultaneous notification a secret number, which is explained in more detail below using a modified number Embodiment will be explained.

Another, to be explained in more detail with reference to FIG. 9 Embodiment can with the cover or seal label according to the present The invention also imprints 10a, 10b on the formed as a shrink film Base layer 1 may be attached, made visible by rubbing or rubbing become. For the application of such imprints 10a, 10b, both sides of the Base layer 1 are used, with the case in which the imprints 10a, 10b at least partially on the underside, that is to say on that of the cover layer 2 facing away from the base layer 1, the use of a transparent base layer 1 recommends.

FIG. 3A shows an embodiment variant of the cover or seal label, which differs from the The embodiment shown in FIG. 2 differs in that the cover layer 2 is made up of two layers, namely a transparent pressure-sensitive adhesive layer 4 and from a covering color layer 3 applied to the pressure-sensitive adhesive layer 4 Color materials for the color layer 3 are particularly suitable for flexographic printing inks, wherein the color layer 3 in Figure 3A is applied by printing. The Pressure sensitive adhesive layer 4, which is formed on the form of a shrink film Base layer 1 is arranged, in turn consists of a removable pressure sensitive adhesive The covering color layer 3 can be removed by rubbing or rubbing, so that the view is released through the cover or seal label. None fall here either annoying waste because the color layer 3 is bound by the pressure-sensitive adhesive layer 4 remains and is, as it were, only pushed aside.

Otherwise, the structure of the embodiment variant from FIG. 3A corresponds to the cover or seal label from FIG. 2. In particular, it is also shown in FIG. 3A Cover or seal label possible, both sides of the base layer 1 as a carrier for Imprints 10a, 10b (see FIG. 9) to use. The cover or shown in Figure 3A The seal label has the advantage that it has no exposed adhesive surfaces. It is therefore not suitable for attaching a credit card or the like. On However, the color layer 3 can be a seal print (not shown) or the like be arranged, which is an additional guarantee for the originality of the color layer 3 supplies.

Figure 3B shows the cover or seal label of Figure 3A on a document 20 is stuck on, under supervision. As can be seen from Figure 3B, the is as Shrink film formed base layer 1 of the cover or seal label by a undulating safety punching 17 divided into individual segments 18. The The cover or seal label serves to print one on the document 20 Cover and seal information 5. The through the cover or Sealed label 5 is shown in Figure 3B by dashed lines Numbers "1234567890" illustrates.

As illustrated by Figure 3C, rubbing off the one in Figure 3C cannot recognizing, covering color layer 3 arranged on the base layer 1 the view on the document 20 and thus on the information 5 can be obtained. in the illustrated embodiment, the color layer 3 is already in an area 19 eliminated so that in this area 19 some digits "34567" of information 5 are already partially recognizable. By "rubbing off" the paint layer 3 however, it is also irreversibly clear that an authorized or unauthorized person has gained knowledge of the information 5. In other words, it delivers The integrity of the cover layer 3 (see FIGS. 3A and 3B) of the justified Person the guarantee that the one covered by the cover or seal label Information 5 in front of him no unauthorized persons have gained knowledge.

The punch 17 prevents anyone from peeling off the cover or Seal labels from its base 20 and then stick it back provides unnoticed knowledge of the information 5. With such a The base layer, which is in the form of a shrink film, would attempt to remove it 1 disassemble into many individual segments 18, which after being detached no longer exactly in the original arrangement to be glued back to document 20 could; this would make the "seal break" recognizable. By using a material low tear strength for the base layer 1 formed as a shrink film a similar safety function can be achieved as through the punch 17.

An embodiment variant with a stamping pattern 17, by which the tearing from Edge is particularly promoted, is shown in Figure 3D. As in Figure 3D recognizable, the punching pattern consists of punching lines that run from the edge of the base film 1 go out and are completed by a transverse line, so that in total each results in a T shape.

Figure 4A shows another embodiment of the cover or seal label, the especially for attaching credit cards or similar ID cards suitable, which are used together with a secret code. The in Figure 4A in Sectional or cover label shown has a base layer 1, the from a transparent shrink film, that is from a transparent thermoplastic and cold stretched plastic film. On top of the Base layer 1 is a cover layer 2, which is composed of two layers is, namely from a transparent pressure-sensitive adhesive layer 4 and from one to the Pressure-sensitive adhesive layer 4 applied covering color layer 3. As color materials for the color layer 3 is particularly suitable for flexographic printing inks, the color layer 3 in Figure 4A is applied by printing.

The color layer 3 does not extend over the entire area of the pressure-sensitive adhesive layer 4, but leaves an edge strip free. The pressure-sensitive adhesive layer 4, which on the as Shrink film formed base layer 1 is composed of a removable pressure sensitive adhesive. On the underside of the base layer 1 is another transparent pressure-sensitive adhesive layer 6 is provided, with which, if desired, the cover or seal label can be attached to an object or document. This further adhesive layer 6 is a permanent adhesive that has a greater adhesive force than the removable adhesive 4. The use of other means instead of the further pressure-sensitive adhesive layer 6, such as, for example Glue, sealing wax or tacking agents is also possible.

It is also possible for both sides of the cover or seal label shown in FIG. 4A to use the base layer 1 as a carrier for prints 10a, 10b (cf. FIG. 9). On the ink layer 3 can be arranged with a seal print, not shown, or the like be, which provides an additional guarantee for the originality of the color layer 3.

Figure 4B shows how the cover or seal label for transmitting a Check card 13 and an associated PIN 5 is used. The cover or seal label is with its further adhesive layer 6 on a letter 20 glued. The peripheral edge strip of the pressure sensitive adhesive 4, which is not covered by the color layer 3 is covered, is used to attach the check card 13.

As is clear from the supervision in FIG. 4C, the cover or seal label is like this glued to the letter paper 20 that the color layer 3 lies over the secret number 5, which is printed on the letterhead 20. The check card 13 is, however, larger than that Cover or seal label and can therefore on their free, on the cover or Sealed label protruding edge area and gripped by the cover or Seal label to be removed. Since the pressure-sensitive adhesive layer 4 consists of a removable Pressure-sensitive adhesive is formed, the check card 13 without adhesive residues and without great effort is removed.

Figure 4D shows the constellation after detaching the check card 13. In Figure 4D is also in particular the free area of the area not covered by the color layer 3 Detect adhesive layer 4, which was used to attach the check card 13 would have. The secret number 5 is not visible at this stage. Your location is merely indicated by dashed lines for illustration.

As illustrated by Figure 4E, by rubbing the on the Pressure-sensitive adhesive layer 4 arranged color layer 3 the view of the letterhead 20 and thus get the secret number 5. There is no annoying waste here either, because the color layer 3 remains bound by the pressure-sensitive adhesive layer 4 and is just pushed aside. In the illustrated embodiment the ink layer 3 has already been removed in an area 19, so that in this area some digits "34567" of the secret number 5 are already partially recognizable. By the "Rubbing" of the color layer 3 is also irreversibly clear that an authorized or unauthorized person has gained knowledge of the PIN 5. Different expressed the integrity of the color layer 3 provides the authorized user the guarantee that the one covered by the cover or seal label PIN 5 before he had no knowledge of unauthorized persons.

Another embodiment of a cover or seal label according to the The present invention is shown in Figure 5A in a sectional view along that in Figure 5B provided section line Va - Va shown. In Figure 5A is one in the form of a Shrink film formed base layer 1 can be recognized by a perforation 22 into an edge-side first area 1a and into a central second area 1b is divided. The base layer 1 is on its lower side in FIG Use of the masking or sealing label for the information to be concealed 5, For example, the information 5 on a sheet of paper 20 facing and in the hereinafter simply referred to as "bottom" for convenience, with glue 6 coated. The adhesive coating 6 is continuous, what under Manufacturing technology has the advantage that a prefabricated, with Adhesive 6 coated film for the production of the cover or seal label can be used. The adhesive layer 6 is in the central second region 1b printed with a layer of lacquer 14 so that the adhesive effect is eliminated there and as a result, the base layer 1 in this second region 1b is non-adhesive. The Lacquer layer 14 extends somewhat over the perforation 22, that is, over the Limits of the second area 1b, which will be explained further below becomes. Instead of printing the second area 1b with the adhesive effect canceling varnish layer can also be achieved by selective application of the adhesive that the second area 1b remains completely free of adhesive. this leads to better transparency in this area. Additionally or alternatively non-adhesive islands can be provided in the edge area (not shown). A Heating then leads to the fact that the base layer is only in the non-sticky islands curled up (evidence of tampering) while the label is in its Whole remains on the object or paper.

FIG. 5A also shows a part of a letter sheet 20 on which a specific one Information 5, such as a bank account number and a bank secret number, are printed. The base layer 1 of the covering or formed as a shrink film Seal label is glued to the letter 20 so that the information 5 dated second, that is covered by the non-adhesive region 1b of the base layer 1. The edge-side first area 1a adheres firmly to the letterhead 20, in particular when a permanent adhesive is used as adhesive 6.

Figure 5B shows the cover or seal label in supervision. In the representation of the figure 5B, part of a letterhead 20 can again be seen on which information 5, here according to the embodiment, the digits "1234567890" are printed. The information 5 is through the base layer 1 of the cover or seal label obscured for what reason it is hatched in Figure 5B.

FIG. 5B shows the first region 1a, which is the second region 1b Encloses base layer 1. The base layer 1 is so on the letter paper 20 stuck on that the information 5 through the second area 1b, that is through the non-adhesive central area are covered. As can be seen in FIG. 5B, the central area 1b on three sides completely from the edge-located first Enclosed area 1a. Only bumps on the side drawn in FIG. 5B the central second area 1b to the outer edge of the first area 1a. The second area 1b has a bottle neck-like taper there. The second At this point, area 1b extends beyond the edge of the first area 1a and forms a tab 23 there.

FIG. 5B also shows that the second area 1b is from the first area 1a is separated by a perforation 22. Furthermore, the first area is 1a provided with a wave-shaped stamping 17 through which the base layer 1 in individual segments 18 is divided.

The information 5 is in this way all around the first area 1a sealed. In the event of an unauthorized person gaining unauthorized access wants to get the information 5 and tries to do this, the first area 1a to lift the base layer 1 from the letterhead 20, this would be a recognizable one Destruction of the base layer 1, which cannot be undone can. Access to information 5 is also not via the one on the left in FIG. 5B drawn side possible, on which the second area 1b to the limits of extends first area 1a. That is because - as already mentioned - the area 1b tapered to a narrow web, so that with conventional means anyway no knowledge of the content of the information 5 either about this left-hand side in FIG. 5B can be obtained.

In order to gain authorized access to the information 5, the authorized users the handle tab 23, which, like the second area 1b, is not is adhesive, grasp and pull the area 1b along the perforation 22 cut out.

The latter constellation is shown in Figure 5C. Since - as mentioned above - the lacquer layer 14 (see FIG. 5A) slightly beyond the perforation line 22 extends into the first area 1a, it is ensured that the entire lower surface of the 5C separated second region 1b is non-adhesive and therefore light can be peeled off without damaging the surface of the letterhead 20. To the "opening" of the cover or seal label, that is after removing the second area 1b, however, is the relationship between the first area 1a and the second area 1b irreversibly destroyed, so that it can be seen that someone has knowledge of the information 5. This means with others Words that as long as the perforation line 22 is intact, the recipient of the Letter 20 can be sure that no one is in front of him in an unauthorized manner Knowledge of the content of the information 5.

For the exemplary embodiment illustrated in FIGS. 5A to 5C, the following, Variants not shown possible: The base layer 1 can be transparent, must in this case, however, in the second area 1b with an opaque printing ink be printed to ensure that the information 5 reliably covered are. About the opaque printing ink on the second area 1b Operating instructions must be printed. Of course, the whole Base layer 1 be made of opaque material.

To attempt to peel off base layer 1 using heat or heat, counteracting effectively can be on the base layer 1 or on parts thereof Temperature indicator such as thermal inks can be attached, which indicates a heating of the Makes base layer 1 irreversibly identifiable. Alternatively or additionally, one can Solvents or cleaning agents reacting to changes in color or bleeding be provided. In this respect, it is a temperature indicator an additional security feature than the main effective protection against the deactivation of the cover or seal label not only by heat or Exposure to heat, but also by steam, by moisture, by acid, Detergent and / or due to environmental influences. In addition, the Base layer 1 is formed in the form of a shrink film, which when heated or irreversibly warps when the cover or seal label is heated or contracts and which the warming or heating of the covering or Makes seal labels irreversibly recognizable.

If the cover or seal label according to FIGS. 5A to 5C is therefore a heat or subjected to heat treatment, the shrink film warps in irreversible, no longer traceable and no longer changeable form, so that an attempt at manipulation is clearly marked on the outside. As a result, it is not just a matter of reapplying the cover or seal label 5A to 5C prevented in a reliable manner, but one also achieved a deterrent effect in that one attempted manipulation making person knows that the manipulation will be discovered immediately.

Figure 6A shows another embodiment of the cover or seal label. The Cover or seal label shown in Figure 6A in turn has one in the form of a Shrink film formed base layer 1 with a first region 1a and with a second region 1b, which are separated from one another by a perforation 22 are. The underside of the base layer 1 is in turn coated with adhesive 6, its adhesive effect by a lacquer layer 14 at least in the second area 1b is canceled. The base layer 1 is in turn due to the action of the adhesive 6 attached to a letterhead 20, which carries information 5. So far Correspondence to the exemplary embodiment from FIGS. 5A to 5C.

In a departure from the exemplary embodiment from FIGS. 5A to 5C, however, the as Shrink film formed base layer 1 another adhesive layer 19 on the the adhesive layer 6 opposite side, which is the simplicity below for the sake of being referred to as the "top". The further adhesive layer 19 consists of a removable adhesive and serves an object 13, such as a Check card to be attached to base layer 1. The adhesive power of the others Adhesive layer 19 is significantly less than the adhesive strength of the adhesive layer 6, so that when detaching the object 13 from the cover or seal label no danger there is that the cover or seal label partially or completely from Sheet 20 with peels off. It is therefore a proper function of the Figures 6A and 6B illustrated embodiment guaranteed.

The object 13 is somewhat larger than the floor plan of the base layer 1, see above that the object 13 survives somewhat over the base layer 1. Figure 6B shows this Constellation under supervision. The object 13 can be attached to the base layer 1 protruding edges can be gripped and detached. As the further layer of adhesive 19 consists of a removable adhesive, the separation takes place without large Exertion of force, so that the connection between the base layer 1 and the letterhead 20 is not affected by this detachment. After removing the Object 13 creates a constellation as it is shown in FIGS. 5B and 5C has already been described above. From a renewed description can so far be disregarded.

FIG. 7 shows a further exemplary embodiment of the present invention in Sectional view. The embodiment shown in Figure 7 differs from the embodiment shown in Figure 5A in that the adhesive 6 on the Partial underside of the base layer 1, that is to say only in the first region 1a is applied, whereas the second area 1b is kept completely free of adhesive 6 is. The application of a paint layer 14 which removes the adhesive force is therefore dispensable.

In the embodiment shown in Figure 7, the top of the Base layer 1 with a removable adhesive for fastening an object 13, such as a check card, as provided by the Embodiment according to Figures 6A and 6B already explained above has been.

Figure 8 shows another embodiment in supervision. In Figure 8, the second, cross-hatched area 1b essentially the shape of a rectangular strip that runs through the entire cover or seal label. The Strip is on one side (in the exemplary embodiment on the left side of FIG. 8) extended beyond the circumferential edge of the first area 1a to the grip tab 23 form. The first area 1a and the second area 1b are as in FIGS Embodiments of Figures 5A to 5C, Figures 6A and 6B and the figure 7, separated by a perforation 22.

The cover or seal label is with pressure sensitive adhesive 6 on a letter paper 20 glued on. For this purpose, the entire base layer 1 is on the letter sheet 20 facing side, that is coated on the underside with adhesive 6. To the To cancel the adhesive effect in the second area 1b is there from the bottom Base layer 1 printed with an opaque printing ink. This will not only the adhesive effect of the pressure sensitive adhesive 6 is eliminated, but also the base layer 1 in second area 1b made opaque so that the is under the second area 1b of the basic layer 1, information 5 located there. To the Making the information 5 visible, the grip tab 23 is gripped and the second Area 1b torn out along perforation 22.

The production of the cover or seal label according to FIG. 8 is special inexpensive because the removal of the adhesive force and the printing of the area 1b in can be done in a single step.

The further exemplary embodiment of a cover shown in FIG. or seal label has a base layer 1, which consists of a transparent thermoplastic shrink film. On the upper side of FIG Base layer 1 is a cover layer 2, which consists essentially of a there is waxy color. Alternatively, it is also possible to use a brittle, use opaque colored material layer as top layer 2. The color of the Cover layer 2 is adapted to the color of the information 5 to be covered. On the On top of the base layer 1 there is also an imprint which is formed by black bars 10a and 10b is symbolized.

On the other side of base layer 1, which is lower in FIG. 9, this is in places printed with a non-stick varnish 9. The non-stick paint 9 can be in the form of a Have lettering, such as "VOID" or "OPEN". On the Non-stick paint 9 is a layer of an adhesion promoter 8 (= so-called "primer") printed. The adhesive layer 8 causes a printed color layer 7th adheres firmly to the base layer 1, at least at the points where the base layer 1 is not printed with non-stick varnish 9. The color layer 7 is finally with a Layer of a pressure sensitive adhesive 6 covered. The non-stick paint 9, the adhesion promoter 8, the color layer 7 and the adhesive layer 6 are circumferential at the edge of the base layer 1 arranged and form one there - as will be explained in more detail below Sealing area covering the central area largely or completely encloses.

In the central area of the base layer 1, this is with a temperature indicator 21 provided, that is, with a chemical substance that when heated or at Heating irreversibly loses its transparency and / or one Color change shows. In this respect, it is the temperature indicator 21 an additional security feature than the main effective protection against the deactivation of the cover or seal label according to FIG. 9 not only through the action of heat or heat, but also through steam, through moisture, by acid and / or by environmental influences is required that the Base layer 1 is formed in the form of the shrink film, which is when heated or irreversible when the cover or seal label is heated according to FIG. 9 warps or contracts and which heats or heats the cover or seal labels according to FIG. 9 irreversibly identifiable.

The cover or seal label illustrated with reference to FIG. 9 is usually used held ready on a siliconized carrier film, not shown. Before the The cover or seal label is used manually or mechanically by the siliconized carrier film separated and by means of the then exposed Adhesive layer 6 glued to an object 20, which is, for example can trade a letterhead.

The cover or seal label according to FIG. 9 is particularly suitable, certain Positions that contain secret key figures 5, for example, in a document 20 to cover. The waxy color of the top layer 2, which corresponds to the color of the Hiding information 5 is easily adapted to a hard object, such as with a coin, rubbed or rubbed off to thereby to release the view of the information 5. According to another, not graphically illustrated embodiment can with the cover or seal label according to the present invention also prints on the base layer 1, the can be made visible by rubbing or rubbing.

After sticking the cover or seal label on the object 20 is liable Color layer 7 over the adhesive layer 6 with a first adhesive force on Item 20; the side of the color layer 7 facing the base layer 1 also adheres a second adhesive force on the base layer 1. The ratio of the first Adhesive force to the second adhesive force is determined locally by that from the Adhesion promoter 8 and 9 consisting of the non-stick paint "Adhesive force setting means" varies, so that in the areas with non-stick paint 9 first adhesive force greater than the second adhesive force and in the areas without Non-stick paint 9, the first adhesive force is less than the second adhesive force. There consequently, the color layer 7 by the action of the adhesion promoter 8 firmly on the Base layer 1 is liable - with the exception of those places where base layer 1 has been prepared with non-stick varnish 9 before application of the adhesion promoter 8 - in an attempt to remove the base layer 1, the color layer 7 in two parts separated.

If the base layer 1 is then glued back onto the object 20, it could the part of the color layer 7 remaining on the base layer 1 is again in the resulting gaps in the color layer 7 are inserted. However, since between the Color layer 7 and the base layer 1 by tearing out parts of the Color layer 7 air has penetrated, these parts have a changed Light reflection behavior compared to the parts of the color layer 7 on the Base layer 1 are left. This can be done through the transparent base layer 1 are observed so that the process of opening is clearly recognizable is made. In this way it becomes apparent that an unauthorized person is acting against unfair practices Weise tried to gain knowledge of the information 5. If it if the information 5 is, for example, a secret number, it must be PIN and the bank card belonging to this PIN are blocked immediately to prevent further abuse and material damage.

The further exemplary embodiment of a cover shown in FIG. or seal label has a base layer 1, which consists of a transparent thermoplastic shrink film. On the upper side of FIG Base layer 1 is a cover layer 2, which consists essentially of a there is an opaque colored ink adhesive. The pressure sensitive adhesive is is a pressure sensitive adhesive with relatively low adhesive strength, which is usually called "Removable pressure sensitive adhesive" is called. The color of the top layer 2 is the color the information to be hidden 5 adapted. Over the top layer 2 is one Check card 13 arranged, which is secure by the adhesive effect of the cover layer 2 is held.

In the central area of the base layer 1, this is with a temperature indicator 21 provided, that is, with a chemical substance that when heated or at Heating irreversibly loses its transparency and / or one Color change shows. In this respect, it is the temperature indicator 21 an additional security feature than the main effective protection against the deactivation of the cover or seal label according to FIG. 10 not only through the action of heat or heat, but also through steam, through moisture, by acid and / or by environmental influences is required that the Base layer 1 is formed in the form of the shrink film, which is when heated or irreversible when the cover or seal label is heated according to FIG. 10 warps or contracts and which heats or heats the cover or irreversibly identifies seal labels according to FIG. 10.

An object 20, for example a letter sheet, is in places with one Non-stick varnish 9 printed. The non-stick paint 9 can have the shape of a lettering, such as for example, "VOID" or "OPEN". About the non-stick paint 9 is one Layer of an adhesion promoter 8 (= so-called "primer") printed. The Adhesion layer 8 causes a printed ink layer 7 firmly on Item 20 is liable, at least where the item 20 is not included Non-stick paint 9 is printed. The color layer 7 is finally made with one layer a pressure sensitive adhesive 6 covered. The non-stick paint 9, the adhesion promoter 8, the Color layer 7 and the adhesive layer 6 are arranged around an area which information 5 to be hidden is on the object 20, and form in this area - as will be explained in more detail below - one Sealing area that contains the information 5 largely or completely encloses.

The base layer 1 with the cover layer 2 and the check card 13 arranged thereon is glued to the adhesive areas created by the pressure-sensitive adhesive layer 6, whereby the structure shown in Figure 10 is created.

The cover or seal label according to FIG. 10 is particularly suitable, certain Positions that contain secret key figures 5, for example, in a document 20 to cover. Since the opaque colored pressure sensitive adhesive is a removable pressure sensitive adhesive, can this after removing the check card 13 easily with a hard object, such as for example, with a coin, rubbed or rubbed off to thereby the To release view of information 5. It has been in this context shown that when rubbing off the opaque colored adhesive layer not the known unpleasant color wastes are released, because the color is bound by the removable adhesive. The Cover or seal label according to Figure 10 is also thanks to its adhesive Cover layer 2 suitable as a fastener for a small object 13, such as for example for a coin or for a check card. The covering or Seal label according to Figure 10 can thus be advantageous when sending check cards 13 can be used with the simultaneous communication of a PIN.

The color layer 7 adheres via the adhesive layer 6 with a first adhesive force on the base layer 1; the side of the color layer 7 facing away from the base layer 1 adheres to the object 20 with a second adhesive force. The ratio of the first Adhesive force to the second adhesive force is determined locally by that from the Adhesion promoter 8 and 9 consisting of the non-stick paint "Adhesive force setting means" varies, so that in the areas with non-stick paint 9 first adhesive force greater than the second adhesive force and in the areas without Non-stick paint 9, the first adhesive force is less than the second adhesive force. There consequently, the color layer 7 due to the action of the adhesion promoter 8 on Item 20 is liable - with the exception of those places where item 20 has been prepared with non-stick varnish 9 before application of the adhesion promoter 8 - in an attempt to remove the base layer 1, the color layer 7 in two parts separated.

If the base layer 1 is then glued back onto the object 20, it could the part of the color layer 7 remaining on the base layer 1 is again in the resulting gaps in the color layer 7 are inserted. However, since between the Color layer 7 and the object 20 by tearing out parts of the Color layer 7 air has penetrated, these parts have a changed Light reflection behavior compared to the parts of the color layer 7, which on the Item 20 have remained. This can be done through the transparent base layer 1 are observed so that the operation of opening the cover or Seal label according to Figure 10 is clearly identified. That way recognizable that an unauthorized person has improperly attempted to withdraw from to provide information 5. If the information is 5 For example, if it is a secret number, this secret number as well as that too bank card belonging to this PIN will be blocked immediately for further Prevent abuse and material damage.

FIG. 11A shows an embodiment variant of the cover or seal label, which itself differs from the embodiment shown in Figure 9 in that the Cover layer 2 is made up of two layers, namely a transparent one Pressure-sensitive adhesive layer 4 and from an opaque layer applied to the pressure-sensitive adhesive layer 4 Color layer 3. Particularly suitable as color materials for the color layer 3 Flexographic printing inks, the ink layer 3 in FIG. 11A being applied by printing is. The pressure-sensitive adhesive layer 4, which is formed on the form of a shrink film Base layer 1 is arranged, in turn consists of a removable pressure sensitive adhesive. The covering color layer 3 can be removed by rubbing or rubbing, so that the view through the cover or seal label is released. Fall here too no annoying waste because the color layer 3 through the pressure-sensitive adhesive layer 4 remains bound and is, as it were, only pushed aside. Otherwise the structure of the cover or seal label according to FIG. 11A corresponds to the structure the cover or seal label according to FIG. 9; in particular it is also in the figure 11A cover or seal label possible, both sides of the base layer 1 as Carrier for imprints 10a, 10b (see FIG. 9) to use.

In FIG. 11A, the color layer 3 does not extend over the entire area of the PSA layer 4, but leaves an edge strip free. The pressure-sensitive adhesive layer 4, which is arranged on the base layer 1, consists of a removable pressure sensitive adhesive. The adhesive effect of the edge area not covered by the color layer 3 serves the attachment of the check card 13.

The use of the covering or Seal labels according to the present invention exemplarily for the in Figure 11A in Exemplary embodiment shown in section explains:

As is clear from the supervision of Figure 11B, is the cover or seal label glued to the letter paper 20 such that the color layer 3 over the secret number 5 lies, which is printed on the letterhead 20. The cover or seal label and the PIN 5 is not visible at this stage; their location is only for Illustration indicated by dashed lines. The check card 13 is larger than that Cover or seal label and can therefore be freely, via the cover or Gripped seal area protruding edge area and from the cover or seal label be separated. Since the pressure-sensitive adhesive layer 4 is formed from a removable pressure-sensitive adhesive is, the check card 13 without adhesive residue and without great effort be removed.

FIG. 11C shows the constellation after detaching the check card 13. FIG. 11C is also in particular the free area of the area not covered by the color layer 3 Detect adhesive layer 4, which has served to secure the check card 13. The secret number 5 is not visible at this stage; their location is only for Illustration indicated by dashed lines.

As illustrated in Figure 11D, by rubbing or rubbing on the pressure-sensitive adhesive layer 4 arranged color layer 3 the view of the letterhead 20 and thus get the secret number 5. No annoying things fall here either Waste because the color layer 3 remains bound by the pressure-sensitive adhesive layer 4 and is just pushed aside. In the illustrated embodiment the color layer 3 is already removed in a partial area, so that in this A few digits "234567" of the secret number 5 are partially recognizable are. By "rubbing off" the color layer 3, however, irreversible Make it clear that an authorized or unauthorized person is not aware of the information 5 Has gained knowledge. In other words, the integrity of the color layer 3 provides the authorized user the guarantee that by the cover or Seal label hidden secret number 5 no unauthorized persons in front of him Have gained knowledge.

Figure 11E shows the constellation after someone has tried by detaching the Base layer 1 to get the secret number 5. Since the color layer 7 due to the adhesive force setting means 8, 9 with locally different adhesive force the base layer 1 and adheres to the object 20, the color layer 7 becomes detached the base layer 1 separated into two parts 7a and 7b, of which the first part 7a the object 20 and the second part 7b remains on the base layer 1. in the Embodiment of Figure 11E, the second part 7b has the shape of the lettering "VOID", whereas the first part 7a has the complementary form. Also after the base layer 1 is stuck back, the lettering "VOID" remains as a result of the changed light reflection properties of the color layer 7 by the transparent Base layer 1 and recognizable through the transparent pressure-sensitive adhesive layer 4.

FIG. 12 shows a further exemplary embodiment of a cover or seal label in Shown sectional view, the information to be hidden 5 on a Underlay 20 are located, on which the cover or seal label with a transparent adhesive layer 6 is fixed. The pad 20 can be Paper, cardboard, or other paper. Above the adhesive layer 6 there is a transparent base layer 1 in the form of a thermoplastic Shrink film on which a cover layer 2 is attached. With this top layer 2 is an opaque color layer made of flexographic printing ink or from a different color.

As can be seen from the illustration in FIG. 12, there is a on the cover layer 2 Authenticity feature 16 applied. The application can depend on the Application, the type and the desired size of the authenticity feature 16 for example by printing. There is also the possibility that Emboss authenticity feature 16 in the top layer 2 in relief. Furthermore, the authenticity feature 16 can be glued or stamped with a hot-melt film. An authenticity feature 16 generated in this way is after a single damage Cover layer 2 is extremely difficult to restore by third parties.

In Figure 13 is another embodiment of the cover or seal label shown. In this exemplary embodiment, the adhesive layer 6 does not cover the entire area provided over the base layer 1 designed as a shrink film, but only in places and here the information 5 is not overlapping. The Adhesive layer 6 therefore does not have to be transparent in order to remove the Cover layer 2 visibly through information 5 through the transparent base layer 1 do. The cover layer 2 extends only over to cover the Information 5 necessary sub-area of the base layer 1. This allows on the one hand a continuation of the authenticity feature 16 on the base layer 1; on the other hand FIG. 14 shows that the part in the form not covered by the cover layer 2 a shrink film formed base layer 1 so space for the application of Patterns, embossing, lettering, serial numbers, die cuts (all not shown here) or adhesive 19 for attaching objects 13 is created. Such a cover or seal label is just in context with the dispatch of credit or check cards 13 in combination with the associated secret numbers 5 particularly suitable because the sender on the secret number 5 covering cover or seal label at the same time an option for attachment the associated card 13 finds.

FIG. 15A shows a further exemplary embodiment of the cover or seal label, the hiding of the information 5 not by pasting it over with the Cover or seal label is achieved, but rather the information 5 part of the Cover or seal labels are and between the top layer 2 and the Base layer 1 are located. This variant has the advantage that the base layer 1 and the adhesive layer 6 does not necessarily have to be transparent.

FIG. 15B illustrates the original condition of a covering or Seal label that adheres to a base 20. The top layer 2 is still intact. An authenticity feature 16 is shown here in the form of a lettering and extends over part of the formed in the form of a shrink film Base layer 1 and over part of the cover layer 2; this ensures that Authenticity feature 16 fulfills its purpose, that is, at least partially damaged if an authorized or unauthorized person contacts the wants to get hidden information 5, the authenticity feature 16 so should be appropriate that it is at least partially directly over the protected Information 5 is located.

Figure 15C shows the same cover or seal label after a partial Damage to the top layer 2. Simultaneously with the top layer 2, this becomes Authenticity feature 16 destroyed at the point where the cover layer 2 by rubbing or is removed by rubbing, and a subsequent recovery is when at all, only possible with very great effort, so that it is guaranteed that by the introduction of the authenticity feature 16 is immediately recognizable whether on the Cover layer 2 was manipulated or not.

The further exemplary embodiment of a cover shown in FIG. or seal labels with an authenticity feature 16 and with a cover layer 2 a base layer 1, which consists of a transparent thermoplastic shrink film consists. An object 20, for example a letter sheet, is in places with one Non-stick varnish 9 printed. The non-stick paint 9 can have the shape of a lettering, such as for example, "VOID" or "OPEN". About the non-stick paint 9 is one Layer of an adhesion promoter 8 (= so-called "primer") printed. The Adhesion layer 8 causes a printed ink layer 7 firmly on Item 20 is liable, at least where the item 20 is not included Non-stick paint 9 is printed. The color layer 7 is with a layer of one Pressure sensitive adhesive 6 covered. The non-stick paint 9, the adhesion promoter 8, the color layer 7 and the adhesive layer 6 are arranged around an area to which hidden information 5 are on the object 20, and form there - how will be explained in more detail below - a sealing area that the Information 5 largely or completely encloses.

The base layer 1, which is designed in the form of a shrink film, can be used, for example the top layer 2 and with a check card 13 arranged thereon on the adhesive Places are glued, which are generated by the pressure-sensitive adhesive layer 6 (see FIG 14).

The color layer 7 adheres via the adhesive layer 6 with a first adhesive force on the base layer 1; the side of the color layer 7 facing away from the base layer 1 adheres to the object 20 with a second adhesive force. The ratio of the first Adhesive force to the second adhesive force is determined locally by that from the Adhesion promoter 8 and 9 consisting of the non-stick paint "Adhesive force setting means" varies, so that in the areas with non-stick paint 9 first adhesive force greater than the second adhesive force and in the areas without Non-stick paint 9, the first adhesive force is less than the second adhesive force. There thus the color layer 7 due to the action of the adhesion promoter 8 firmly on the object 20 is liable - with the exception of those places where the item 20 is present Applying the adhesion promoter 8 with non-stick varnish 9 has been prepared - at an attempt to remove the base layer 1, the color layer 7 in two parts separated.

If the base layer 1 is then glued back onto the object 20, it could the part of the color layer 7 remaining on the base layer 1 is again in the resulting gaps in the color layer 7 are inserted. However, since between the Color layer 7 and the object 20 by tearing out parts of the Color layer 7 air has penetrated, these parts have a changed Light reflection behavior compared to the parts of the color layer 7, which on the Item 20 have remained. This can be done through the transparent base layer 1 are observed so that the process of opening is clearly recognizable is made. In this way it becomes apparent that an unauthorized person is on has attempted to gain knowledge of the information 5 unfairly. For example, if the information 5 is a secret number, must have this PIN and the bank card belonging to this PIN be blocked immediately to prevent further abuse and material damage prevent.

The further exemplary embodiment of a cover shown in FIG. or seal labels with authenticity feature 16 also under the top layer 2 a base layer 1, which consists of a transparent thermoplastic shrink film consists. This is in places on the lower side of the base layer 1 in FIG. 17 printed with a non-stick varnish 9. The non-stick paint 9 can be in the form of a Have lettering, such as "VOID" or "OPEN". On the Non-stick paint 9 is a layer of an adhesion promoter 8 (= so-called "primer") printed. The adhesive layer 8 causes a printed color layer 7th adheres firmly to the base layer 1, at least at the points where the base layer 1 is not printed with non-stick varnish 9. The color layer 7 is made with one layer a pressure sensitive adhesive 6 covered. The non-stick paint 9, the adhesion promoter 8, the Color layer 7 and adhesive layer 6 are circumferential at the edge of base layer 1 arranged and form - as will be explained in more detail below - one Sealing area covering the central area largely or completely encloses.

The exemplary embodiment of a cover or Seal labels are usually placed on a label that is not shown in FIG siliconized carrier film ready. Before use, the cover or Seal label separated from the siliconized carrier film manually or by machine and glued to an object 20 by means of the then exposed adhesive layer 6 which can be a letterhead, for example.

After sticking the cover or seal label on the object 20 is liable Color layer 7 over the adhesive layer 6 with a first adhesive force on Item 20; the side of the color layer 7 facing the base layer 1 also adheres a second adhesive force on the base layer 1. The ratio of the first Adhesive force to the second adhesive force is determined locally by that from the Adhesion promoter 8 and 9 consisting of the non-stick paint "Adhesive force setting means" varies, so that in the areas with non-stick paint 9 first adhesive force greater than the second adhesive force and in the areas without Non-stick paint 9, the first adhesive force is less than the second adhesive force. There consequently, the color layer 7 by the action of the adhesion promoter 8 firmly on the Base layer 1 is liable - with the exception of those places where base layer 1 has been prepared with non-stick varnish 9 before application of the adhesion promoter 8 in an attempt to remove the base layer 1, the color layer 7 in two parts separated.

If the base layer 1 is then glued back onto the object 20, it could the part of the color layer 7 remaining on the base layer 1 is again in the resulting gaps in the color layer 7 are inserted. However, since between the Color layer 7 and the base layer 1 by tearing out parts of the Color layer 7 air has penetrated, these parts have a changed Light reflection behavior compared to the parts of the color layer 7 on the Base layer 1 are left. This can be done through the transparent base layer 1 are observed so that the process of opening is clearly recognizable is made. In this way it becomes apparent that an unauthorized person is on has attempted to gain knowledge of the information 5 unfairly. For example, if the information 5 is a secret number, must have this PIN and the bank card belonging to this PIN be blocked immediately to prevent further abuse and material damage prevent.

Figure 18 shows the constellation after an authorized or unauthorized person has tried by removing the base layer 1 designed as a shrink film to the Secret number 5 to arrive, at the same time damaging the authenticity feature 16 to bypass:

Since the color layer 7 is due to the use of the adhesive force setting means 8, 9 with locally different adhesive force on the base layer 1 and on the object 20 adheres, the color layer 7 becomes when the base layer 1 is separated into two parts 7a and 7b separated, of which the first part 7a on the object 20 and the second Part 7b remain on the base layer 1. In the exemplary embodiment according to FIG. 18 the second part 7b has the shape of the lettering "VOID", whereas the first part 7a which has a complementary form. Even after sticking back the base layer 1 remains the lettering "VOID" due to the changed light reflection properties of the Color layer 7 can be seen through the transparent base layer 1.

In all of the exemplary embodiments shown, it is advantageous if a Interference pattern, scatter pattern or random pattern is provided, which is in the range of is arranged to conceal writing. The scatter pattern prevents for example a secret number when the label is screened with an intensive one Light source can be read through the different layers. The Scatter patterns can be printed on the carrier on which the label is attached or it can be inside the scratch layer.
