Abstract
Official abstract text for this publication.
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
Opening claim text (preview).
That which is claimed is: 1. An aerosol delivery device comprising: a heating member formed of a heating element conformed to a heater substrate, the heater substrate comprising a film or membrane underlying the heating element, wherein the heater substrate is configured as a truncated cone having a first end of a first size and a second end of greater size, and wherein the heating element comprises an electrically conductive ink printed on the heater substrate; and a porous transport element configured for passage of an aerosol precursor composition along a length thereof, wherein the porous transport element has a first end in a heating arrangement with the heating member, wherein the truncated cone includes an interior passage therethrough, and wherein the first end of the porous transport element in the heating arrangement with the heating member is positioned at least partially within the interior passage of the truncated cone. 2. The aerosol delivery device according to claim 1 , wherein the heater substrate further comprises a film or membrane overlying the heating element. 3. The aerosol delivery device according to claim 2 , wherein one or both of the heater substrate and the film or membrane overlying the heating member comprises a textured surface. 4. The aerosol delivery device according to claim 3 , wherein the texturing is configured to provide for capillary flow across the textured surface.
