ELECTRONIC CIGARETTE WITH MULTICAMERAL LIQUID RESERVOIR

The present invention concerns an electronic smoking device that includes a battery portion (12) comprising a battery (18), an atomizer/liquid reservoir portion (14) comprising a multicameral liquid reservoir (34), and an atomizer (26) operable when connected to the battery (18) to atomize liquid stored in the multicameral liquid reservoir (34). The multicameral liquid reservoir (34) comprises a first chamber (202) comprising an unflavored fluid, a second chamber (204) comprising a flavored fluid, the first chamber (202) and the second chamber (204) being disposed in communication with each other via an opening (206), and a plurality of reservoir walls (208) enclosing the two chambers. A portion of the plurality of reservoir walls (208) enclosing the second chamber (204) comprising a flexible portion (40), the flexible portion (40) when acted upon causing the flavored fluid to migrate from the second chamber (204) to the first chamber (202) through the opening (206).
