  • Patent number: 5865892
    Abstract: An expandable stamp pad comprising a plurality of ink pads arranged in a line and suitable for use with a multitude of different aqueous dye-based inks, and methods of using the same. Typically, the line is straight, although, if desired, the line may be curved. The plurality of ink pads are retained on an extension member that permits adjacent ink pads to contact one another when the extension member is retracted, (e.g., in use) while maintaining the plurality of ink pads in separation when the extension member is extended (e.g., in storage). Also, a multi-color stamp pad suitable for use with aqueous dye-based inks wherein a plurality of ink pads each impregnated with a different ink have disposed therebetween a thin, aqueous-impermeable film, such as a thin plastic film. Preferably, the stamp pad comprises more than two ink pads, further preferably five or more ink pads.

  • Patent number: 5531829
    Abstract: A fan-shaped stamp pad that provides from one to a multitude of differently colored inks to a single stamp, at the option of a user. Additionally, the fan-shaped stamp pad permits the application of a great number of colors of ink to a stamp while requiring only one application of the stamp to the stamp pad, thereby reducing the chance of smearing, or otherwise contaminating, the ink from one section of the pad to another.
