Abstract:
1. A method for emitting two or more volatile compositions, said method comprising providing two or more different volatile compositions comprising at least a first volatile composition and a second volatile composition, wherein said first and second volatile compositions are emitted by heating the compositions and dispensing them through a wick, and further, wherein said first and second volatile compositions are emitted in a substantially continuous emission sequence in which the emission of the different volatile compositions automatically alternates between the different volatile compositions in the sequence, wherein in said alternating sequence: (a) said first volatile composition is emitted for a first time period, said first time period having a beginning and an end; (b) said second volatile composition is emitted for a second time period, said second time period having a beginning and an end, and said second time period begins at one of the following times: (c) after the beginning of said second period, said first volatile composition is emitted again, and the pattern repeats; wherein said different volatile compositions are emitted during discrete emission periods, said discrete emission periods are each from 23⅓ minutes to less than 120 minutes in length.
