  • Patent number: 7083353
    Abstract: The writing pen creates a background of metallic coated under-layers embossed with strings of impressions on a writing medium. The pen comprises a cartridge with a removable cap connected to the non-writing end of the pen. The cartridge acts as a cylindrical housing for a replaceable sub-cartridge, which stores a coating substance. An out-feeding roller is rotatably disposed, in proximity with the sub-cartridge to receive the coating substance. An intermediate roller is rotatably disposed to receive the coating substance from the out-feeding roller for onward transmission to an embossing and metal coating roller. The embossing and metal coating roller has projections on its surface and is rotatably disposed in the cylindrical housing to generate a unique string of repeated impressions in quick succession on a writing medium. The rollers meshed together to form a gear train to provide a cumulative radial drive to the embossing and coating roller.
