Abstract

The present disclosure relates to aerosol delivery devices including a cartridge and a control body. The control body may include a coupler and the cartridge may include a base. The base may be configured to releasably engage the cartridge. Further the base and the coupler may include anti-rotation mechanisms configured to prevent rotation of the cartridge relative to the base when engaged with one another. The anti-rotation mechanisms may include alternating protrusions and recesses in some embodiments. Related methods are also provided.

Claims

1. An aerosol delivery device, comprising:

a control body comprising;

a control component;

an electrical power source; and

a coupler comprising a plurality of electrical contacts, the coupler extending between a body end oriented toward the control component and the electrical power source and a connector end comprising an anti-rotation mechanism; and

a cartridge comprising;

a reservoir substrate configured to hold an aerosol precursor composition;

an atomizer configured to atomize the aerosol precursor, the atomizer comprising a plurality of heater terminals; and

a base extending between a body end oriented toward the reservoir substrate and the atomizer and a connector end configured to releasably engage the control body, the heater terminals extending at least partially through the base, the connector end of the base comprising an anti-rotation mechanism,

the base being configured to engage the coupler such that the anti-rotation mechanism of the base engages the anti-rotation mechanism of the coupler to prevent rotation of the cartridge relative to the control body and the heater terminals engage the electrical contacts to electrically couple the cartridge to the control; and

wherein the anti-rotation mechanism of the base comprises a plurality of protrusions and a plurality of recesses alternatingly disposed about an inner periphery thereof and the anti-rotation mechanism of the coupler comprises a plurality of protrusions and a plurality of recesses alternatingly disposed about an outer periphery thereof; and

wherein a width of each of the protrusions of the base and the protrusions of the coupler increases from the connector end toward the body end and a width of each of the recesses of the base and the recesses of the coupler respectively decreases from the connector end toward the body end.

2. The aerosol delivery device of claim 1, wherein the base further comprises a plurality of ribs extending from the inner periphery thereof at the recesses.

3. The aerosol delivery device of claim 1, wherein a radial dimension of the inner periphery of the base decreases from the connector end toward the body end and a radial dimension of the outer periphery of the coupler increases from the connector end toward the body end.

4. The aerosol delivery device of claim 1, wherein the base further comprises a groove extending at least partially around the inner periphery thereof and the coupler further comprises a circumferential protrusion extending at least partially around the outer periphery thereof.

5. A method for forming an aerosol delivery device, the method comprising:

providing a control body comprising;

a control component;

an electrical power source; and

a coupler comprising a plurality of electrical contacts, the coupler extending between a body end oriented toward the control component and the electrical power source and a connector end comprising an anti-rotation mechanism, the anti-rotation mechanism of the coupler comprising a plurality of protrusions and a plurality of recesses alternatingly disposed about an outer periphery thereof; and

providing a cartridge comprising;

a reservoir substrate configured to hold an aerosol precursor composition;

an atomizer configured to atomize the aerosol precursor, the atomizer comprising a plurality of heater terminals; and

a base extending between a body end oriented toward the reservoir substrate and the atomizer and a connector end comprising an anti-rotation mechanism, the heater terminals extending at least partially through the base, the anti-rotation mechanism of the base comprising a plurality of protrusions and a plurality of recesses alternatingly disposed about an inner periphery thereof; and

engaging the connector end of the base to the connector end of the coupler such that the cartridge releasably engages the control body, the anti-rotation mechanism of the control body engages the anti-rotation mechanism of the cartridge to substantially prevent rotation of the cartridge relative to the control body, and the heater terminals engage the electrical contacts to electrically couple the cartridge to the control body; and

wherein a width of each of the protrusions of the base and the protrusions of the coupler increases from the connector end toward the body end and a width of each of the recesses of the base and the recesses of the coupler respectively decreases from the connector end toward the body end.

6. The method of claim 5, wherein engaging the connector end of the base to the connector end of the coupler further comprises engaging a plurality of ribs extending from the inner periphery of the base at the recesses with the protrusions of the control body.

7. The method of claim 5, wherein engaging the connector end of the base to the connector end of the coupler further comprises engaging a circumferential protrusion extending at least partially around the outer periphery of the coupler with a groove extending at least partially around the inner periphery of the base.
