1. An electronic cigarette comprising:
- a mouthpiece configured to receive air with vapor;
a soft fluid bladder storing a fluid and configured to prevent excess air in the bladder by collapsing as the fluid is removed;
a member configured to support the soft fluid bladder;
a porous material coupled with the soft fluid bladder and configured to transfer a portion of the fluid; and
an atomizer configured to receive the portion of the fluid transferred from the porous material, wherein the atomizer is configured to generate the vapor by heating the transferred fluid.

Abstract
An aerosol delivery device or electronic cigarette generates an aerosol or vapor for consumption by a consumer. The device may include a cartridge holding an aerosol precursor substance or fluid that is turned into the aerosol or vapor. The fluid may be stored in reservoir that allows for the fluid to be passed to an atomizer for generating the aerosol. The reservoir may be a flexible bladder that equalizes pressure inside the cartridge to reduce leakage, such as with an internal valve to activate fluid transfer. Alternatively, the reservoir may include one or more capsules that can be broken or melted to release the fluid.

11. An aerosol delivery device comprising:
-
a container storing an aerosol precursor substance; a moveable wall enclosed by the container that is configured to move relative to the container to release the aerosol precursor substance; and a vaporizer configured to receive the aerosol precursor substance after the moveable wall causes the releasing, wherein the vaporizer generates an aerosol by vaporizing the aerosol precursor substance. - View Dependent Claims (12, 13, 14, 15, 16)

17. A vaporization device comprising:
-
a battery portion; and a cartridge configured to receive power from the battery portion and to store a fluid, the cartridge comprising; a flexible bladder configured to hold the fluid that equalizes a pressure inside the flexible bladder to control leakage caused by pressure changes, wherein the equalization of pressure is due to a shape of the flexible bladder collapsing as the fluid is removed; a porous material coupled with the flexible bladder that is configured to transfer at least a portion of the fluid from the flexible bladder; and a heating element configured to generate vapor from the fluid. - View Dependent Claims (18, 19, 20)
