Volatile carrier for use with a heating device has a reservoir block that is limited to move in only discrete increments

摘要

A volatile carrier (10) for supplying a volatile ingredient to a heating device (12) to be dispensed thereby, the heating device (12) having a heat transfer site and a pass-through path to receive an inserted volatile carrier at one end of the pass-through path to position the volatile carrier adjacent to the heat transfer site. The volatile carrier has a substantially unitary reservoir block containing a supply of the volatile ingredient. The reservoir block is greater in size than the heat transfer site. An advancement device is supplied by which a user can manually advance the reservoir block past the heat transfer site to expose different portions of the reservoir block to heat. A method of supplying a volatile ingredient to such a heating device by use of such a volatile carrier is also described.
