摘要

A self-sealing stamping device suitable for use with non-alcohol based inks is described. The stamping device includes an applicator that has raised features for providing a stamped design. The applicator also includes sealing features that mate with sealing features on an inkpad housing to provide one or more airtight seals therebetween. The inkpad housing provides an enclosure for an inkpad with one or more apertures. Sealing features are provided circumscribing the apertures for mating with sealing features of the applicator. In a closed position, the stamping device provides an airtight enclosure for the inkpad comprised of the inkpad housing and the applicator.

1. A self-sealing stamping device comprising:
an applicator having one or more raised features on a stamping surface for transferring an ink to a marking surface, wherein the applicator includes a sealing feature around an exterior perimeter of the stamping surface; an inkpad housing having an aperture with an interior perimeter operably configured to receive the stamping surface of the applicator, wherein the inkpad housing includes a sealing feature around the interior perimeter of the aperture, wherein an airtight seal is formed between the inkpad housing and the applicator when the stamping device is in a closed position based on mating the sealing feature around the exterior perimeter of the stamping surface with the sealing feature around the interior perimeter of the aperture of the inkpad housing, and further wherein at least a portion of one or more of the applicator and the inkpad housing comprises a chitin-based polyurethane material; and a mechanism for rotatably actuating the applicator from the closed position facing and contacting the inkpad housing to a stamping position facing and contacting the marking surface.
