Abstract:
1. A method for creating a negative bias pressure within a sealed reservoir, the method comprising: providing a liquid reservoir coupled with an aerosol generator, the aerosol generator comprising an aperture plate, the aperture plate having a liquid side and an air side; storing a liquid in the liquid reservoir, the liquid reservoir having a head space; providing a cap, wherein the cap comprises a flexible seal and a pivot portion; sealing the liquid reservoir to create the sealed reservoir by the flexible seal of the cap being inserted into the head space of the liquid reservoir and then pivoted into position by pivoting the pivot portion of the cap against the liquid reservoir to seal the liquid reservoir and fill at least a portion of the head space of the liquid reservoir, wherein: vibrating the aperture plate to dispense the portion of the liquid, wherein: decreasing the amount of liquid in the sealed reservoir creates a negative bias pressure as compared to the air side of the aperture plate.
