COMBUSTIBLE INSECT REPELLENT OR INCENSE COIL

摘要

Insect repellent or incense in coils or other configurations is made substantially of a combustible hydrocarbon material especially amorphous carbon. The amorphous carbon may be charcoal or activated carbon. Particularly and advantageously, insect repellent or incense coils are made by grinding and mixing charcoal or activated carbon, a binder agent, and water into a paste. The paste is extruded to form a flat sheet. A coil imprint is stamped in turn on said flat sheet. The imprints are either dipped in or sprayed with chemicals-in-alcohol solution. The chemicals include an active ingredient and perfume (in the case of making insect repellent) perfume (in the case of making incense). The treated imprints are air-dried and then packed.
