Abstract

The present disclosure relates to aerosol delivery devices, methods of forming such devices, and elements of such devices. In some embodiments, the present disclosure provides a heating member that can be formed of a heating element conformed to a heater substrate configured as a truncated cone (or similar shape) having a first end of a first size and a second end of greater size. In some embodiments, the disclosure provides methods of forming an aerosol delivery device, which can include providing a shell, providing a heating member formed of a heating element conformed to a substrate, configuring the heating member as a truncated cone (or similar shape) having a first end of a first size and a second end of greater size, and inserting the heating member within the shell.

First claim

That which is claimed is:

1 . An aerosol delivery device comprising:
a heating member extending between a first electrical terminal and a second electrical terminal in a curved arrangement; a liquid transport element arranged to transport an aerosol precursor composition to the heating member; and a frame member within which the heating member and the liquid transport element are at least partially positioned.

2 . The aerosol delivery device of claim 1 , wherein the liquid transport element is at least partially surrounding the heating member.

3 . The aerosol delivery device of claim 1 , wherein the liquid transport element comprises a plurality of layers of fibrous material.

4 . The aerosol delivery device of claim 1 , wherein the liquid transport element is configured so that at least a portion thereof has a substantially tubular shape and defines a central passage therethrough.

5 . The aerosol delivery device of claim 1 , wherein the heating member comprises a metal that provides resistive heating.

6 . The aerosol delivery device of claim 1 , wherein the heating member is configured as a metal ribbon.

7 . The aerosol delivery device of claim 1 , wherein the heating member, the liquid transport element, and the frame member are arranged in a shell.

8 . The aerosol delivery device of claim 7 , further comprising a liquid storage within the same shell.

9 . The aerosol delivery device of claim 8 , further comprising one or both of a control component and a power component within the same shell.

10 . The aerosol delivery device of claim 1 , wherein the frame member comprises a metal.

11 . The aerosol delivery device of claim 1 , wherein the frame member has an open free end.

12 . The aerosol delivery device of claim 1 , wherein the heating member and the liquid transport element are arranged within the frame member with the liquid transport element positioned between the heating member and the frame member.

13 . The aerosol delivery device of claim 1 , wherein a portion of the liquid transport element extends outward from the frame member.
