Definitions

  • This invention relates to a security labelling system for deterring the theft of portable articles and for assisting in the recovery of such articles if they are lost or stolen.
  • This invention provides a security labelling system for portable articles comprising a label having an underside marked with fluorescent ink and an adhesive for securing the underside of the label to the article so that the ink cannot be removed without damaging the article, the label including opaque material which protects the ink from exposure to light until that material is removed following loss or theft of the article.
  • the invention could take the form of a single sheet of opaque plastics material or metal carrying a warning message on its upper surface and the fluorescent message on its underside.
  • epoxy resin adhesive applied over the fluorescent marking, would be used to attach the label to the article to be protected. Should it be stolen, the label would be difficult to remove without causing damage, and even if removed would expose the visible or invisible fluorescent marking, absorbed into any adhesive remaining on the stolen article.
  • the fluorescent ink should be applied to one side of a transparent sheet, this transparent sheet being covered by an opaque cover-sheet to which it is attached using an adhesive less strong than the first-mentioned adhesive.
  • the thief does manage to remove the cover sheet, in doing so he exposes the transparent sheet and the fluorescent marking, which can then be detected by the police. Even if the transparent sheet is in some way ground away, the marking will still be retained by absorption into the adhesive and/or the material of the article.
  • the upper or under surface of the transparent sheet can also carry a visible non-fluorescent marking.
  • the opaque cover-sheet should overlap the edges of the transparent sheet.
  • the transparent sheet is preferably of polyester material having a coating of a composition conventionally used for inkjet printing of transparencies.
  • Such coatings which may include an ink absorbent porous polymer layer, have been found to retain the fluorescent ink without risk of smudging either the fluorescent ink or any normal ink which might also be printed on the same surface.
  • the opposite surface of the sheet is preferably left uncoated so that it is relatively smooth. This ensures that, if a thief does manage to remove the cover sheet, the adhesive remains on the cover sheet in preference to the transparent sheet and does not unduly damage the transparency thereof.
  • Fig 1 is a perspective view, shown partly cut away to illustrate a cross-section, of a security label constructed in accordance with the invention and employing a cover sheet of synthetic plastics material;
  • Figs 2A, 2B, and 2C illustrate progressive steps in the application, to a portable article, of a security label similar to that of Fig 1 but employing a metal cover sheet; and
  • Fig 3 is a perspective view, shown partly cut away to illustrate a cross-section of a variant embodiment of a security label shown in Fig 1.
  • the illustrated security label employs a cover sheet 1 of synthetic plastics material which is sufficiently flexible to fit around curved surfaces.
  • the cover sheet 1 carries printing 2 on its upper surface typically containing a warning message, a logo, contact details of a central registry, and an identification code which allows the registry to identify the person to whom the label has been issued.
  • the printed material is covered with a protective and decorative dome-shaped shaped layer 3 of clear synthetic plastics material.
  • the underside of the cover sheet 1 carries, at a central portion thereof, a thin layer 4 of contact adhesive, completely surrounded by a border region which is clear of adhesive.
  • a thin transparent sheet 5 of polyester inkjet transparency film having an uncoated, shiny, surface which is applied to the adhesive, and an absorbent coating on its under surface.
  • two images are printed.
  • One of these images, 5A might typically include the word "STOLEN” and a repeat of the information on the cover sheet 1. This is printed in black and coloured inks using an inkjet printer.
  • the image 5 A is then overprinted with the image 5B using fluorescent ink in an inkjet printer. After printing, the film is cut to size and its shiny face is applied to the sticky film 4 at the centre of the cover sheet 1.
  • an industrial strength epoxy adhesive 6 is thinly applied over the whole lower surface which is then applied to the article 7 to be protected.
  • the whole label is sufficiently flexible to conform to the shape of a curved surface if so required. If a determined attempt is made to remove the label it is possible that the plastics cover sheet 1 could be torn away from the smooth upper surface of the transparent film 4, only to reveal a repeat of the warning message visible through the film. Removing this message is impossible without damaging the article 7 since it is embedded in the epoxy adhesive which becomes inseparable from the article. Even if the epoxy resin were ground off in places 5A where the message appears, the thief would not know that the invisible fluorescent message remains in other places 5B.
  • Fig 2 shows, at A, B and C, a product similar to that of Fig 1 equivalent parts being denoted with reference numerals identical to those of Fig 1.
  • this security label has a cover sheet 1A made of metal but sufficiently thin to bend to the shape of a curved article.
  • the metal sheet 1A is anodised at IB and carries printing 2 protected with clear plastic 3 as for the Fig 1 embodiment.
  • the whole under surface of the cover sheet carries contact adhesive 4, this being protected with a release sheets 4A(in the centre) and 4B around the edges.
  • the central release sheet 4 A is removed and a clear plastic film 5, identical to that of Fig 1, is pressed into the adhesive, as show on Fig 2B. Finally, epoxy resin adhesive is applied to the central portion, over the film 5 and the label is pressed onto the article 5 as shown in Fig 2C.
  • the Fig 2 embodiment works in a similar fashion to that of Fig 1, except that a determined effort to remove the label will result in the component parts parting along the line of the contact adhesive 4, leaving just the film 5 and its associated visible and invisible messages irremovably attached to the article.
  • Fig 3 illustrates a variation embodiment of Fig 1.
  • the label comprises a cover sheet made from either synthetic plastics material or metal sheet carrying printing 2 and domed shaped layer 3.
  • the underside of the cover sheet 1 carries, at a central portion thereof, a thin layer 4 of contact adhesive completely surrounded by a border region or well 8 which is clear of adhesive.
  • the well 8 is itself surrounded by a border layer 9 of contact adhesive.
  • a thin transparent sheet 5 is secured to the central portion of contact adhesive 4. It is preferable that the dimensions of the transparent sheet
  • the contact adhesive of border layer 9 may be protected before use by a single release sheet which may be removed immediately before use.
  • Industrial strength epoxy adhesive 6 is thinly applied over the under surface of transparent sheet 5 which is then applied to the article 7 to be protected.
  • the whole label is sufficiently flexible to conform to the shape of a curved surface if so required.
  • the well 8 holds and inhibits excess epoxy 6 from transgressing outside the edge of the plate which would otherwise look unsightly.
  • the border layer 9 of contact adhesive also promotes the preferential separation of the cover sheet 1 from the transparent sheet 5 rather than the transparent sheet 5 from the article 7.
  • Fig 3 shows the thickness of the border layer 9 to be greater than that of the central portion 4, in practice, these thicknesses may be the same, with any inconsistencies in the topography of the lower surface of the label caused by the application of epoxy
  • the fluorescent writing might be visible so as to make a potential thief aware that there is a UV marking but unsure whether, any attempt to remove it has been completely successful.

Abstract

Une pratique commune destinée à aider à la récupération de marchandises volées consiste à marquer des articles avec un code de propriétaire au moyen d'une encre fluorescente invisible à la lumière normale mais qui devient visible lorsqu'on l'irradie avec des ultraviolets. Ce procédé est complètement inefficace pour décourager le vol des articles marqués et, des articles doivent être remarqués tous les six ou douze mois car l'encre exposée perd sa fluorescence après une exposition continuelle à la lumière. Ces problèmes sont résolus par une étiquette possédant une face arrière marquée avec une encre fluorescente (5B) et un adhésif (6) destiné à coller la face arrière de cette étiquette à un article de sorte que cette encre ne peut être retirée sans détérioration de l'article. Cette étiquette comprend une feuille de recouvrement opaque (1) portant un message d'avertissement (2). Cette étiquette protège l'encre (5B) d'une exposition à la lumière jusqu'à ce qu'on la retire à la suite de la perte ou du vol de l'article.
