Abstract

The present disclosure relates to an aerosol delivery device, an input for such devices, and methods of preparing such devices. In some embodiments, the present disclosure provides a method of forming an aerosol delivery device, which can comprise providing a fibrous substrate, providing a shell, wetting the fibrous substrate with a wetting liquid, and inserting the wetted fibrous substrate into the shell. After the inserting step, the shell further can comprise one or more of a heater, a liquid transport element, and an electrical connection. In some embodiments, the present disclosure provides an input that can comprise a liquid transport element, a heater in a heating arrangement with the liquid transport element, and a wetted fibrous substrate wrapped around at least a portion of the liquid transport element.

Claims

1. A method for adding an aerosol precursor composition to an aerosol delivery device comprising:

providing a fibrous substrate and a shell of the aerosol delivery device;

adding a portion of the aerosol precursor composition to the fibrous substrate prior to combining the fibrous substrate with the shell;

combining the fibrous substrate with the shell; and

adding a remainder of the aerosol precursor composition to the fibrous substrate after combining the fibrous substrate with the shell.

2. The method according to claim 1, wherein the aerosol precursor composition comprises water, and wherein the method comprises adding all or a portion of the water to the fibrous substrate prior to combining the fibrous substrate with the shell.

3. The method according to claim 1, wherein the fibrous substrate has a maximum liquid retention capacity, and wherein, after adding the portion of the aerosol precursor composition to the fibrous substrate but prior to combining the fibrous substrate with the shell, a mass of any liquid in the wetted fibrous substrate is less than 75% of the maximum retention capacity.

4. The method according to claim 1, wherein the portion of the aerosol precursor composition is only a single component of the aerosol precursor composition.

5. The method according to claim 4, wherein the single component of the aerosol precursor composition is water.

6. The method according to claim 4, wherein the single component of the aerosol precursor composition is a polyol.

7. The method according to claim 1, wherein the fibrous substrate is a nonwoven material.

8. The method according to claim 1, wherein the fibrous substrate comprises cellulose acetate.
