Abstract

The present disclosure relates to aerosol delivery devices and related methods of delivering aerosol to a user. The aerosol delivery devices include a housing providing multiple aerosol pathways having a mouth-end opening through which aerosol can be inhaled by a user, the housing defining a first aerosol delivery pathway in fluid communication with the mouth-end opening and a second aerosol delivery pathway separate from the first aerosol delivery pathway and in fluid communication with the mouth-end opening. An atomizer including a heating element or piezoelectric element and a liquid transport element in fluid communication with an aerosol precursor composition is provided in fluid communication with the first aerosol delivery pathway. A flavorant-infused material is positioned within the second aerosol delivery pathway and adapted to produce a second aerosol upon contact between the flavorant-infused material and flowing air.

First claim

The invention claimed is:

1 . An aerosol delivery device, comprising:
a first housing providing multiple aerosol pathways having a mouth-end with one or more openings through which aerosol can be inhaled by a user, the first housing defining a first aerosol delivery pathway in fluid communication with at least one of the one or more openings and a second aerosol delivery pathway separate from the first aerosol delivery pathway and in fluid communication with at least one of the one or more openings; a reservoir located within the first housing or a second housing separate from the first housing, the reservoir containing a liquid aerosol precursor composition; an atomizer located within the first housing or the second housing, the atomizer being in fluid communication with the reservoir, the atomizer adapted to produce a first aerosol from the liquid aerosol precursor composition, the atomizer positioned in fluid communication with the first aerosol delivery pathway, wherein the atomizer is in fluid communication with a first air inlet; a flavorant-infused material positioned within the second aerosol delivery pathway and adapted to produce a second aerosol upon contact between the flavorant-infused material and flowing air, the flavorant-infused material positioned in fluid communication with a second air inlet.

2 . The aerosol delivery device of claim 1 , wherein the liquid aerosol precursor composition is substantially flavorant-free and optionally comprises nicotine.

3 . The aerosol delivery device of claim 1 , wherein the flavorant-infused material comprises a liquid solution or emulsion comprising a liquid carrier and a flavorant admixed with the liquid carrier, or comprises a substrate and a releasable flavorant carried by the substrate.

4 . The aerosol delivery device of claim 1 , wherein the flavorant-infused material is in the form of one or more porous monoliths, beads, particles, gels, capsules, and coatings.

5 . The aerosol delivery device of claim 1 , wherein the first housing further defines a mixing area downstream from the first and second aerosol delivery pathways and adapted to allow mixing of the first and second aerosols prior to exit from the one or more openings in the mouth-end.

6 . The aerosol delivery device of claim 1 , wherein the first housing comprises a plurality of different flavorant-infused materials, each flavorant-infused material positioned within a separate aerosol delivery pathway and in fluid communication with a separate air inlet.

7 . The aerosol delivery device of claim 6 , further comprising a mouth-end cap having first and second apertures, the first aperture downstream from, and in fluid communication with, the first aerosol delivery pathway and the second aperture downstream from, and in fluid communication with, at least one of the separate aerosol delivery pathways having a flavorant-infused material positioned therein.

8 . The aerosol delivery device of claim 7 , wherein the mouth-end cap is rotatable such that the user can move the second aperture into fluid communication with at least one of the separate aerosol delivery pathways having a flavorant-infused material positioned therein.

9 . The aerosol delivery device of claim 6 , further comprising a first aerosol delivery pathway and a plurality of separate aerosol delivery pathways, wherein a first opening is in fluid communication with the first aerosol delivery pathway and a plurality of different openings are in fluid communication with each of the plurality of separate aerosol delivery pathways having a flavorant-infused material positioned therein.

10 . The aerosol delivery device of claim 1 , wherein the atomizer is located within the second housing upstream from the first housing providing multiple aerosol pathways, the first housing providing multiple aerosol pathways being fixedly or removably attached to the separate second housing.

11 . The aerosol delivery device of claim 1 , wherein the first aerosol delivery pathway is centrally located within the first housing and the second aerosol delivery pathway is an annular region surrounding the first aerosol delivery pathway.

12 . The aerosol delivery device of claim 11 , wherein the annular region surrounding the first aerosol delivery pathway is divided into a plurality of separate aerosol delivery pathways, each containing a different flavorant-infused material and in fluid communication with a separate air inlet.

13 . The aerosol delivery device of claim 12 , further comprising a mouth-end cap having first and second apertures, the first aperture downstream from, and in fluid communication with, the first aerosol delivery pathway and the second aperture downstream from, and in fluid communication with, at least one of the separate aerosol delivery pathways having a flavorant-infused material positioned therein.

14 . The aerosol delivery device of claim 13 , wherein the mouth-end cap is rotatable such that the user can move the second aperture into fluid communication with different aerosol delivery pathways having a flavorant-infused material positioned therein.

15 . The aerosol delivery device of claim 12 , wherein a first opening is in fluid communication with the first aerosol delivery pathway and a plurality of different openings are in fluid communication with each of the plurality of separate aerosol delivery pathways having a flavorant-infused material positioned therein.

16 . The aerosol delivery device of claim 1 , further comprising a heater positioned to heat at least a portion of the flavorant-infused material positioned within the second aerosol delivery pathway.

17 . The aerosol delivery device of claim 1 , wherein the flavorant-infused material comprises a liquid solution or emulsion comprising a liquid carrier and a flavorant admixed with the liquid carrier, and wherein an aerosol jet array is positioned within the second aerosol delivery pathway to form droplets from the flavorant-infused material.

18 . The aerosol delivery device of claim 1 , wherein the atomizer is located within the housing providing multiple aerosol pathways.

19 . The aerosol delivery device of claim 18 , wherein the first aerosol delivery pathway and the second aerosol delivery pathway are in a side-by-side configuration within the first housing.

20 . The aerosol delivery device of claim 1 , wherein at least one breakable capsule containing an internal payload comprising a flavorant is positioned within the second aerosol delivery pathway.

21 . The aerosol delivery device of claim 1 , further comprising a rotatable absorbent material in fluid communication with a flavorant-infused material comprising a liquid solution or emulsion comprising a liquid carrier and a flavorant admixed with the liquid carrier, the rotatable adsorbent material adapted to produce droplets of the flavorant-infused material during rotation.

22 . The aerosol delivery device of claim 1 , wherein the first aerosol is respirable and the second aerosol is non-respirable.

23 . The aerosol delivery device of claim 1 , further comprising one or more of:
