Definitions

  • This invention relates to a security label for inhibiting tampering with equipment to which such a label is applied in use.
  • Electronic equipment such as cellular telephones, iPodsTM, television sets, laptops, computers, keyboards and computer components are usually sold together with a guarantee which guarantees the working parts of the piece of equipment for a specified amount of time.
  • Tamper-proof stickers/ labels which indicate exposure to a fluid are applied to electronic equipment. These stickers can often be removed by applying heat to melt the adhesive on the sticker or they can be removed using a solvent or water after which they are replaced with a similar sticker to cover up tampering or the indication of exposure to fluid.
  • a security label including a thermal indicator for indicating whether the label has been heated above a predetermined temperature and a fluid damage indicator for indicating whether the label has come into contact with a liquid or a vapour.
  • the thermal indicator may be a first zone of the label and the fluid damage indicator may be a second zone.
  • the thermal indicator may be a first layer and the fluid damage indicator may be a second layer.
  • the thermal indicator may be a first chemical composition applied to a carrier or substrate material or from which a carrier material is made.
  • the fluid damage indicator may be a second chemical composition applied to a carrier or substrate material or from which a carrier material is manufactured.
  • the label may be provided with an adhesive backing layer which may be covered with a removable sheet.
  • the label may be attached to a piece of equipment by removing the sheet and sticking the label onto the piece of equipment at a zone at which tampering is likely to occur.
  • the label may be in the form of a sheet or token associated with an article so that, in use, if the article is exposed to heat or fluid the label indicates said exposure.
  • the label may in use, for example, be applied over a fastening means which holds in place a cover of a housing in which working parts of the piece of electronic equipment are housed.
  • the fastening means may be in the form of a screw, a clip, a bolt, and the like.
  • the thermal indicator may be a thermochromic coating which irreversibly changes colour when the label is heated above a predetermined temperature.
  • the colour it changes to may be grey or black or any other colour.
  • the predetermined temperature may be from -10 degrees Celcius, typically from fifty degrees Celsius but may be 500 degrees Celsius.
  • thermochromic coating may be applied to a portion of the label which acts as a substrate.
  • the fluid damage indicator may be a coating, reactive security ink, or dye that runs, smudges, or irreversibly changes colour when exposed to a liquid or a vapour.
  • the colour it changes to may be pink or black or yellow or orange, however, it may become invisible or completely wash away .
  • the coating may be applied to a portion of the label which acts as a substrate to define the fluid damage indicator.
  • the coating may include Rhodamine and/or Aquableed, which is a dye which smudges, causes streaks or run marks on the substrate or completely washes off when exposed to a liquid or a vapour, especially water, or an equivalent thereof
  • thermochromic coating when used in respect of a coating or a dye means that when a substrate has the coating or dye applied to it, for example by printing on the substrate, then if the dye or coating is exposed to a liquid or a vapour the coating or dye causes streaks and stains on the substrate or completely washes off the substrate so that it becomes apparent that the substrate got wet or moist.
  • the thermochromic coating may be applied to the label using a printing process. As such, the thermochromic coating may form part of a logo, wording or bar code that is applied to the label.
  • the coating defining the second zone may be applied to the label using a printing process.
  • the second zone may form part of a logo, wording or bar code that is applied to the label.
  • the label may include several first and second zones which may preferably be arranged in an alternating pattern.
  • the label may be frangible so that it loses its integrity when an attempt is made at removing the label from a surface to which it has been applied.
  • the label may be manufactured from tamper evident material such as destructible polypropylene, polyester, polyethylene or acetate destructible label material or foam tac or paper.
  • the label may include weakened zones which cause disintegration of the label when an attempt is made to remove the label from a surface to which it has been applied.
  • the weakened zones may be in the form of slits or so-called “enhanced" slits.
  • the label may include several layers which may become separated from each other when an attempt is made at removing the label from a surface to which it has been applied.
  • the label may include a third zone which may be a verification zone for verifying that the label has been applied to a piece of electronic equipment by the manufacturer thereof.
  • the verification zone may include one or more microdots carrying unique identifier data, a watermark, an RFID circuit, or a hologram.
  • a portion of the label may be printed with a thermal transfer ribbon which may contain UV properties which becomes visible under a UV light.
  • the printing may be of an image or graphic.
  • the dimensions and shape of the label may be selected according to the dimensions and shape of the area which it is to cover in use.
  • the label may, for example, be round and have a diameter of 1 mm or it may be square, rectangular, triangular, or any other suitable shape with a maximum side length of 300mm.
  • the label may be laminated with a partially permeable material to slow down permeation of water onto the fluid damage indicator thereby to reduce false positive fluid contact indications.
  • the material used for the lamination may include the one or more microdots carrying unique identifier data, the watermark, the RFID circuit, or the hologram.
  • Figure 1 shows a first embodiment of a security label in accordance with the present invention
  • Figure 2 shows a second embodiment of a security label in accordance with the present invention.
  • Figure 3 shows a third embodiment of a security label in accordance with the present invention.
  • reference numeral 10 generally indicates an embodiment of a security label in accordance with the present invention.
  • the security label 10 includes two zones, wherein a first zone 12 is a thermal indicator for indicating whether the label 10 has been heated above a predetermined temperature (which can be any desired negative or positive temperature as described above) and wherein a second zone 14 is a fluid damage indicator for indicating whether the label 10 has come into contact with a liquid or a vapour.

Abstract

L'invention concerne une étiquette de sécurité (10) qui présente une couche de base (16) sur laquelle au moins deux revêtements délimitant la première et la seconde zone (12 et 14) sont appliqués. La première zone (12) est délimitée par un revêtement thermochromique qui change de couleur de manière irréversible lorsque l'étiquette (10) est chauffée au-dessus d'une température voulue pouvant être positive ou négative. La couleur change en gris ou noir lorsqu'elle est exposée à la chaleur. Le revêtement thermochromique délimitant la première zone (12) est appliqué sur la couche de base (16) par un procédé d'impression. La seconde zone (14) est délimitée par un revêtement qui change de couleur de manière irréversible ou macule lorsqu'elle est exposée à un liquide ou à une vapeur.
