Abstract

The present disclosure relates to an aerosol delivery device. The aerosol delivery device may include a first outer body, a second outer body, and a coupler defining a coupler inlet positioned between, and welded to, the first outer body and the second outer body. A sealing member may be engaged with the coupler, the sealing member including one or more penetrable portions, wherein the one or more penetrable portions of the sealing member are configured to be pierced with one or more electrical connectors such that the one or more electrical connectors extend through the sealing member from the coupler and seal against the sealing member. Related assembly methods are also provided.

Claims

1. An aerosol delivery device, comprising:

a first outer body;

a second outer body;

a power source positioned in the first outer body;

an atomizer positioned in the second outer body;

one or more electrical connectors configured to electrically connect the atomizer to the power source;

a coupler defining a first engagement portion, a second engagement portion, an outer rib positioned between the first engagement portion and the second engagement portion, an annular recess positioned at an end of the second engagement portion, at least one connector aperture configured to receive the one or more electrical connectors, a coupler inlet disposed on the first engagement portion, and a longitudinal channel in fluid communication with the coupler inlet; and

a sealing member defining an annular shape, the sealing member comprising one or more penetrable portions, at least two inner ribs disposed about an interior of the annular shape and at least one outer rib disposed about an exterior of the annular shape;

wherein the sealing member is arranged within the annular recess of the coupler such that the at least two inner ribs seal against the inner surface of the annular recess and the at least one outer rib seals against the outer surface of the annular recess;

wherein the one or more electrical connectors are configured to pass through the at least one connector aperture of the coupler and to pierce and extend through the one or more penetrable portions of the sealing member;

wherein the sealing member is configured to seal against the coupler and the one or more electrical connectors;

wherein the first engagement portion is welded to the first outer body and the second engagement portion is welded to the second outer body; and

wherein the coupler is configured to receive air through the coupler inlet and to direct the air to the atomizer in the second outer body through the longitudinal channel.

2. The aerosol delivery device of claim 1, further comprising a reservoir and a flow director positioned in the second outer body, the flow director extending at least partially through the reservoir.

3. The aerosol delivery device of claim 2, wherein the coupler defines a nipple and the flow director engages the nipple of the coupler.

4. The aerosol delivery device of claim 2, further comprising a flow director fastener extending at least partially around the flow director and a slit defined through the flow director.

5. The aerosol delivery device of claim 2, further comprising a mouthpiece assembly defining a nipple, wherein the flow director engages the nipple of the mouthpiece assembly.

6. The aerosol delivery device of claim 5, further comprising a substrate fastener extending at least partially around the flow director and the nipple of the mouthpiece assembly, the substrate fastener being configured to retain the reservoir in a selected position.

7. The aerosol delivery device of claim 1, wherein the atomizer extends linearly between first and second ends of the atomizer.

8. The aerosol delivery device of claim 1, wherein the coupler is laser welded to the first outer body and the second outer body.

9. The aerosol delivery device of claim 1, wherein the outer rib of the coupler is configured to separate the first outer body from the second outer body.

10. The aerosol delivery device of claim 1, wherein the coupler further defines a recessed portion at a peripheral surface of the first engagement portion, and wherein the coupler inlet is defined through the recessed portion.

11. The aerosol delivery device of claim 1, wherein the coupler defines one or more separator extensions and a pressure port proximate the first outer body and in fluid communication with the coupler inlet, the one or more separator extensions being configured to prevent the power source from blocking the pressure port.

12. The aerosol delivery device of claim 11, wherein the pressure port extends into the longitudinal channel to resist leakage into the first outer body.

13. A method for assembling an aerosol delivery device, the method comprising:

positioning a power source in a first outer body;

positioning an atomizer in a second outer body;

providing one or more electrical connectors configured to electrically connect the atomizer to the power source;

providing a coupler defining a first engagement portion, a second engagement portion, an outer rib positioned between the first engagement portion and the second engagement portion, an annular recess positioned at an end of the second engagement portion, at least one connector aperture configured to receive the one or more electrical connectors, a coupler inlet disposed on the first engagement portion, and a longitudinal channel in fluid communication with the coupler inlet;

providing a sealing member defining an annular shape, one or more penetrable portions, at least two inner ribs disposed about an interior of the annular shape and at least one outer rib disposed about an exterior of the annular shape;

positioning the sealing member within the annular recess of the coupler such that the at least two inner ribs seal against the inner surface of the annular recess and the at least one outer rib seals against the outer surface of the annular recess;

engaging the first engagement portion of the coupler with the first outer body and the second engagement portion of the coupler with the second outer body such that the coupler is positioned between the first outer body and the second outer body and configured to receive air through the coupler inlet and to direct the air to the atomizer in the second outer body through the longitudinal channel;

positioning the one or more electrical connectors such that the one or more electrical connectors pass through the at least one connector aperture of the coupler, pierce and extend through the one or more penetrable portions of the sealing member and connect the atomizer to the power source;

sealing against the coupler and the one or more electrical connectors with the sealing member; and

welding the first engagement portion of the coupler to the first outer body and the second engagement portion of the coupler to the second outer body.

14. The method of claim 13, further comprising positioning a reservoir and a flow director in the second outer body such that the flow director extends at least partially through the reservoir.

15. The method of claim 14, further comprising coupling the flow director to a nipple of the coupler.

16. The method of claim 14, further comprising engaging a flow director fastener with the flow director such that the flow director fastener extends at least partially thereabout.

17. The method of claim 14, further comprising coupling the flow director to a nipple of a mouthpiece assembly.

18. The method of claim 17, further comprising engaging a substrate fastener with the flow director such that the substrate fastener extends at least partially around the nipple of the mouthpiece assembly.

19. The method of claim 13, wherein welding the first engagement portion of the coupler to the first outer body and the second engagement portion of the coupler to the second outer body comprises laser welding the first engagement portion of the coupler to the first outer body and the second engagement portion of the coupler to the second outer body.
