Definitions

  • This invention relates to secrecy protection in communicating written messages.
  • a typical application is in communicating codes (such as the code of a rechargeable telephone card or of a credit card) or other messages written on a sheet, card etc., to a user by the organization providing the service.
  • Another known system uses self-adhesive labels with a transparent plastic laminar surface which have their lower surface covered with permanently adhering glue and their upper surface covered with a layer of scratch-off ink adhering to the support.
  • a label is applied to the message to be protected. Again in this case the ink layer has to be scratched off to read the message, hence again revealing that this action has been taken.
  • This system is simple and economical to apply. In particular, it requires the use of devices (of the type suitable for applying self-adhesive labels to sheets and the like) which are simple and are easy to use even by inexperienced personnel, and is hence suitable for many different applications and usable by personnel without particular expertise and without special machinery.
  • An object of the invention is to provide a method, and the relative article carrying the secret communication, which protects the message secrecy much more reliably than the known system using self-adhesive labels with scratch-off ink, while at the same time, in its preferred embodiment, requiring merely the application of a self-adhesive label with scratch-off ink and the necessary application devices, which are relatively very simple and easy to use.
  • the reference numeral 10 indicates an article acting as a movable support for a written message. This can be a sheet of cardboard, as in the illustrated example, or a sheet of paper, plastic etc.
  • said lower ink film 21 is applied to the support article 10 using a self-adhesive label 20 comprising a transparent laminar plastic support 22 (in particular of polyester) having its lower surface covered with a thin layer of permanently adhering glue 23 (also transparent), and having on its upper surface said film of opaque ink 21, which is of scratch-off type and adheres to the support 22.
  • a self-adhesive label 20 comprising a transparent laminar plastic support 22 (in particular of polyester) having its lower surface covered with a thin layer of permanently adhering glue 23 (also transparent), and having on its upper surface said film of opaque ink 21, which is of scratch-off type and adheres to the support 22.
  • Said label 20 is of known type, available commercially and known as a "self-adhesive scratch-off label". Brand names of these labels include "ARCA ETICHETTE R ", "EUROLABEL R” and “ETIKA R ".
  • At least one of these labels 20 is applied to the surface of the article 10, so that a lower ink film 21 rigidly adheres to the article.
  • the secret message (for example a code) is then written on said lower ink film 21 so as to be visible on the ink film 21.
  • the message is typically printed on the film 21 with an ink of different colour.
  • the written parts of the message are shown schematically in Figure 1, where they are indicated by 11.
  • a transparent laminar plastic support 32 which carries on its upper surface an upper adhering film 31 of opaque ink (or equivalent covering material) of the type able to be scratched off the plastic support 32 in small disintegrated particles by a hard sharp-edged object.
  • the support 32 and the relative film 31 are adheringly applied to said lower ink film 21 such as to cover and hide the written message 11.
  • said upper ink film 31 is applied to the lower film 21 using a self-adhesive label 30 comprising a transparent laminar plastic support 32 (in particular of polyester) having its lower surface covered with a thin layer of permanently adhering glue 33 (also transparent), and having on its upper surface a film of opaque ink, which is of scratch-off type and adheres to the support 32.
  • a self-adhesive label 30 comprising a transparent laminar plastic support 32 (in particular of polyester) having its lower surface covered with a thin layer of permanently adhering glue 33 (also transparent), and having on its upper surface a film of opaque ink, which is of scratch-off type and adheres to the support 32.
  • said label 30 is identical to the label 20.
  • the plastic upper support 32 is uncovered, and being transparent enables the message lying below it to be seen.
  • the support 32 itself is formed of a material which is not substantially scratched by the object with which the film 31 is scratched off. In contrast, this latter is formed of a layer of covering material (typically ink) which, while remaining adhering to the support 32 during normal handling, easily crumbles when scratched, to uncover the support 32 and hence allow the underlying message 11 to be seen.
  • the message 11 can only be read by scratching off the upper ink layer 31, this having the required result of leaving a clear and unerasable indication of the fact that this action has been accomplished.
  • the films of scratch-off ink 21 and 31 are absolutely opaque to better conceal the message 11.
  • Figure 2 is an exploded view of an article, in particular a sheet of paper, cardboard or plastic, for secret message communication, prepared by the aforedescribed method, and in particular the article 10 shown in Figure 1.
  • the article 10 carries a lower self-adhesive label 20 which utilizing its self-adhesive properties is applied to the surface of the sheet 10.
  • the message (code) which is to be kept secret is written on the upper surface of the label 20.
  • An upper self-adhesive label 30, in particular of greater length and width than the lower label 20, is applied over the lower label 20 to totally cover this and also conceal its perimetral edge.
  • the sheet 10 formed in this manner is enclosed within an envelope composed of two sheets, namely an upper sheet 41 and a lower sheet 42, which are joined together along their respective perimetral edges 41' and 42'.
  • the upper sheet 41 also possesses a window 43 enabling the region carrying the secret message to be inspected.
  • the invention enables relatively very secure protection to be provided for the secret message.
  • this is achieved using and applying a (known) self-adhesive label with scratch-off ink, requiring simple and inexpensive devices (of the type suitable for applying a self-adhesive label to sheets and the like), and hence suitable for many uses in various fields, it moreover being usable by users without particular expertise and without special machines.
