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, and said discrete emission periods are each greater than 35 minutes in length and less than 120 minutes in length.
