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). ## Claims ### Claim 1 An electronic cigarette (10), comprising: 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), wherein said multicameral liquid reservoir (34) comprising: a first chamber (202) comprising an unflavored fluid, a second chamber (204) comprising a flavored fluid, said first chamber (202) and said second chamber (204) disposed in communication with each other via an opening (206), and a plurality of reservoir walls (208) enclosing said first (202) and second (204) chamber, wherein a portion of said plurality of reservoir walls (208) enclosing said second chamber (204) comprising a flexible portion (40), said flexible portion (40) when acted upon causing said flavored fluid to migrate from the second chamber (204) to the first chamber (202) through said opening (206). ### Claim 2 (depends on 1) The electronic cigarette (10) of claim 1, wherein when acting upon said flexible portion (40) an internal pressure of said flavored fluid is increased causing said flavored fluid to migrate from the second chamber (204) to the first chamber (202). ### Claim 3 (depends on 1) The electronic cigarette (10) of claim 1, wherein a volume of said first chamber (202) is larger than a volume of said second chamber (204). ### Claim 4 (depends on 1) The electronic cigarette (10) of claim 1, wherein said flexible portion (40) forming an outside portion of said atomizer/liquid reservoir portion (14) of the electronic cigarette (10). ### Claim 5 (depends on 1) The electronic cigarette (10) of claim 1, wherein said second chamber (204) comprising a capsule (300) comprising said flavored fluid, and wherein said capsule (300) is adapted to break due to pressure exerted upon the capsule (300) via said flexible portion (40). ### Claim 6 (depends on 5) The electronic cigarette (10) of claim 5, wherein the capsule (300) is disposed within said second chamber (204) between said flexible portion (40) of said plurality of reservoir walls (208) and said opening (206). ### Claim 7 (depends on 1) The electronic cigarette (10) of claim 1, wherein said opening (206) comprising a first valve (400). ### Claim 8 (depends on 1) The electronic cigarette (10) of claim 1, wherein a portion of said plurality of walls (208) enclosing said second chamber (208) comprising a second valve (400). ### Claim 9 (depends on 8) The electronic cigarette (10) of claim 8, wherein said second valve (400) is a unidirectional valve capable of functioning as an air inlet. ### Claim 10 (depends on 7) The electronic cigarette (10) of claim 7, wherein said first valve (400) is a unidirectional valve. ### Claim 11 (depends on 7) The electronic cigarette (10) of claim 7, wherein said first valve (400) is a bidirectional pin hole valve. ### Claim 12 (depends on 7) The electronic cigarette (10) of claim 7, wherein the atomizer (26) comprising a heating coil (28) and a wick (30), and wherein said wick (30) is disposed in the proximity of the opening (206) between said first (202) and second chambers (204). ### Claim 13 An atomizer/liquid reservoir portion (14), comprising: a multicameral liquid reservoir (34), and an atomizer (26) operable when connected to a battery (18) of an electronic cigarette (10) to atomize liquid stored in the multicameral liquid reservoir (34), wherein the multicameral liquid reservoir (34) comprising: a first chamber (202) comprising an unflavored fluid, a second chamber (204) comprising a flavored fluid, said first chamber (202) and said second chamber (202) disposed in communication with each other via an opening (206), and a plurality of reservoir walls (208) enclosing said first (202) and second chamber (204), wherein a portion of said plurality of reservoir walls (208) enclosing said second chamber (204) comprising a flexible portion (40), said flexible portion (40) when pressed causing said flavored fluid to migrate from the second chamber (204) to the first chamber (202) through said opening (206). ### Claim 14 (depends on 13) The atomizer/liquid reservoir portion (14) of claim 13, wherein when pressing said flexible portion (40) an internal pressure of said flavored fluid is increased causing said flavored fluid to migrate from the second chamber (204) to the first chamber (202). ### Claim 15 (depends on 13) The atomizer/liquid reservoir portion (14) of claim 13, wherein said flexible portion (40) forming an outside portion of said atomizer/liquid reservoir portion (14) of electronic cigarette (10).
