Abstract
A heat-curlable identification carrying means comprising a transparent sheet, and an adhesive backing layer for attaching the means to a substrate, the means optionally having an intermediate sheet bearing or suitable for bearing indicia.
Claims7
Identification carrying means that curls on heating, comprising a transparent sheet that curls on heating and an adhesive layer bonded thereto along portions only of the surface of the transparent sheet, which surface becomes concave on heating, the areas of bonding allowing the insertion of a further sheet between the transparent sheet and the adhesive layer, wherein the transparent sheet is formed of a crosslinked thermoplastic material that has been deformed from a curled configuration to a room-temperature stable planar configuration.
Identification carrying means that curls on heating, comprising a transparent sheet that curls on heating and an adhesive layer bonded thereto along portions only of the surface of the transparent sheet, which surface becomes concave on heating, the areas of bonding allowing the insertion of a further sheet between the transparent sheet and the adhesive layer, wherein the adhesive is heat-activatable and the temperature at which the transparent sheet curls being a temperature at which the adhesive layer becomes functional.
Substantially flat identification carrying means for application to a curved surface comprising:
- a substantially flat transparent sheet which upon heating curls about a single axis to become concave;
- a heat-activatable adhesive layer bonded to selected portions of only one of the surfaces of the transparent sheet, said surface being the surface which becomes concave upon curling, the adhesive being activatable at a temperature at which the transparent sheet curls;
- and
- a pocket between the transparent sheet and the adhesive layer wherein the areas of bonding allow the insertion of identification means into the pocket.
