  • Patent number: 6663838
    Abstract: A heated volatile dispenser and a volatile carrier for use therewith are disclosed. The volatile dispenser has a closed heating chamber having ceiling and exit vents. A fuel burner is contained within the heating chamber, and a carrier holder is positioned over the fuel burner. The carrier holder holds a volatile carrier in a location above the fuel burner such that hot gases from the fuel burner pass the carrier holder and directly heat a volatile carrier held thereby. The volatile carrier may be held in an edge-on orientation with respect to the flow of hot gases, or transversely with respect to them. The volatile carrier has an inward end that has a cross-sectional profile made to be complementary to that of an insert slot through which the volatile carrier must be inserted for use. An alternative embodiment is shown that uses a candle as a fuel burner.

  • Patent number: 6389739
    Abstract: Disclosed herein is a container for holding a burnable coil bearing an active ingredient, such as an insecticide, insect repellant, deodorizer, or fragrance. The container includes a base having a raised coil support for mounting the coil and a spiral recess or spirally arrayed support peaks which permit air circulation beneath the coil and inhibit premature snuffing. The coil is enclosed by a cover having a downwardly depending hold-down aligned with the coil support to prevent the coil from moving in the container. The cover also has openings allowing air to pass into the container and vapors to be released. The cover is rotatably mounted to the base so that the cover openings can be selectively opened and closed to allow controlled venting and snuffing of the coil.
