Abstract
Cartridges for vaporizer devices are provided. In one exemplary embodiment, the cartridge can include a primary reservoir, a secondary reservoir in fluid communication with the primary reservoir, and a vaporization chamber in communication with the secondary reservoir in which the vaporization chamber includes a first wicking element. The primary reservoir is configured to store a majority fraction of vaporizable material when in a first pressure state and configured to expel the vaporizable material in response to an increase in headspace when in a second pressure state. The secondary reservoir is formed of absorbent material configured to receive a first volume of the vaporizable material from the primary reservoir in the first pressure state and to receive a second volume of the vaporizable material from the primary reservoir in the second pressure state in which the second volume is greater than the first volume. Vaporizer devices are also provided.
