Abstract

The present disclosure relates to a cartridge for an aerosol delivery device such as a smoking article. The cartridge may include a base, a reservoir substrate, and an atomizer. The reservoir substrate may define a cavity therethrough. The atomizer may comprise a liquid transport element and a heating element extending at least partially about the liquid transport element. The atomizer may extend through the cavity through the reservoir substrate such that the heating element is positioned proximate an end of the reservoir substrate. Ends of the liquid transport element may extend to an opposing end of the reservoir substrate. A related method for assembling a cartridge for a smoking article is also provided.

First claim

The invention claimed is:

1 . A cartridge for a smoking article, the cartridge comprising:
a cartridge body comprising a connector end; an atomizer arranged to aerosolize an aerosol precursor composition, the atomizer comprising a plurality of terminals extending from the atomizer through the connector end so as to be exposed about connecting ends, wherein each one of the plurality of terminals comprises a contact surface electrically coupled with the atomizer; wherein the plurality of terminals extend through the connector end so as to be exposed about connecting ends for direct contact with electrical contacts of a control body, and wherein when the connector end is brought into engagement with the control body, the electrical contacts of the control body engage the contact surfaces.

2 . The cartridge of claim 1 , wherein the atomizer comprises a resistive heating element arranged to aerosolize the aerosol precursor composition.

3 . The cartridge of claim 1 , further comprising a mouth end of the cartridge body opposing the connector end, the mouth end defining an opening of the cartridge body configured to receive suction.

4 . The cartridge of claim 3 , wherein the atomizer receives uninterrupted current flow for up to a defined period during application of suction to the opening of the mouth end of the smoking article.

5 . The cartridge of claim 1 , further comprising a reservoir configured to hold the aerosol precursor composition.

6 . The cartridge of claim 5 , wherein the reservoir defines a cavity extending therethrough from a first reservoir end to a second reservoir end, wherein the first reservoir end is positioned proximate the connector end and the second reservoir end is positioned proximate a mouth end opposite the connector end, wherein the cavity includes an opening adjacent to the first reservoir end adapted for exit of aerosol therefrom.

7 . The cartridge of claim 1 , wherein the connector end is configured to engage the control body via press-fit engagement or magnetic engagement.

8 . The cartridge of claim 5 , further comprising a liquid transport element extending between a first liquid transport element end and a second liquid transport element end, the liquid transport element being configured to transport the aerosol precursor composition to the atomizer from the reservoir for aerosolization thereof.

9 . The cartridge of claim 1 , wherein the smoking article defines a quadrilateral-shaped cross-section such that one or both of the cartridge body and the control body defines a quadrilateral-shaped cross-section.

10 . The cartridge of claim 2 , wherein the resistive heating element comprises a wire defining a plurality of coils wound about a liquid transport element extending between a first wire end and a second wire end.

11 . The cartridge of claim 1 , wherein the cartridge body further comprises an air intake positioned between the contact surfaces.

12 . The cartridge of claim 3 , wherein the mouth end comprises a mouthpiece engaged with the cartridge body.

13 . The cartridge of claim 12 , wherein the mouthpiece is retained in engagement with the cartridge body via engagement of corresponding protrusions and indentations.
