Abstract

Smoking articles and a method for making a smoking article are provided. The smoking articles include an aerosol-generating element configured to produce an aerosol in response to heat, a housing defining a cavity configured to receive the aerosol-generating element therein, a heating element engaged with the housing and configured to provide heat to the aerosol-generating element, a power source in electrical communication with the heating element and configured to provide electrical energy thereto, the heating element producing heat in response to the electrical energy, an aerosol-generating element identification device configured to identify an attribute of an aerosol-generating element and a control device in communication with the aerosol-generating element identification device and configured to modulate electrical energy provided to a heating element of the smoking article to direct the heating element to heat the aerosol-generating element to an aerosolization temperature associated with the identified attribute of the aerosol-generating element.

First claim

That which is claimed:

1. A smoking article comprising:
an attribute identifier engaged with the aerosol-generating element;
a housing defining a cavity configured to receive an aerosol-generating element therein, the aerosol generating element including at least one constituent component configured to produce aerosol in response to heat; and
an aerosol-generating element identification device engaged with the housing and configured to interact with the attribute identifier to identify, upon actuation of the aerosol-generating element identification device, an attribute of the aerosol-generating element, the attribute being associated with at least a maximum aerosolization temperature of the at least one constituent component of the aerosol-generating element, as indicated by the attribute identifier, the aerosol-generating element identification device being configured to identify the attribute through analysis of the at least one constituent component of the aerosol-generating element, or through user input to the aerosol-generating element identification device regarding the maximum aerosolization temperature of the at least one constituent component of the aerosol-generating element.

2. The article of claim 1 , further comprising:
a heating element operably engaged with the housing and configured to provide heat to the aerosol-generating element;
a power source in electrical communication with the heating element and configured to provide electrical energy thereto, the heating element producing heat in response to the electrical energy; and
a control device in communication with the aerosol-generating element identification device and configured to modulate the electrical energy provided to the heating element by the power source so as to direct the heating element to heat the aerosol-generating element to an aerosolization temperature associated with the identified attribute of the aerosol-generating element, the aerosolization temperature being at least the maximum aerosolization temperature of the at least one constituent component of the aerosol-generating element.

3. The article of claim 2 , wherein the housing comprises an outer wall defining the cavity such that the cavity is a cylindrical cavity.

4. The article of claim 3 , wherein the heating element comprises a first portion configured to extend about the outer wall and a second portion configured to extend within the cylindrical cavity.

5. The article of claim 4 , wherein the control device is configured to modulate the electrical energy provided to the first portion separately and discretely from the electrical energy provided to the second portion of the heating element so as to provide for individual control of the first and second portions.

6. The article of claim 2 , wherein the aerosol-generating element identification device comprises an attribute identification detector configured to detect the attribute identifier identifying the attribute of the aerosol-generating element.

7. The article of claim 6 , wherein the attribute identifier comprises a Universal Product Code (UPC) barcode, a QR-Code, or a radio-frequency identification (RFID) device identifying the attribute of the aerosol-generating element.

8. The article of claim 6 , wherein the attribute identification detector comprises a camera, a wireless transceiver, or a scanner configured to detect, upon actuation thereof, the attribute identifier, and to identify the attribute of the aerosol-generating element associated therewith, and to communicate the identification of the attribute to the control device.

9. The article of claim 1 , wherein a second attribute identifier is provided on a packaging of the aerosol-generating element.

10. The article of claim 2 , wherein the attribute of the aerosol-generating element further includes a flavor, a heating profile of the at least one constituent component of the aerosol-generating element, a wattage for controlling the power source relative to the maximum aerosolization temperature of the at least one constituent component of the aerosol-generating element, or combinations thereof.

11. The article of claim 2 , wherein the aerosol-generating element identification device comprises a processor configured to execute an algorithm to identify the attribute of the aerosol-generating element associated therewith, and to communicate the identification of the attribute to the control device.

12. The article of claim 11 , wherein the aerosol-generating element identification device is configured to analyze the aerosol-generating element to determine the at least one constituent component thereof, determine the maximum aerosolization temperature of the at least one constituent component, and to communicate the determined maximum aerosolization temperature to the control device, and wherein the control device is configured to modulate the electrical energy provided to the heating element by the power source in response to the determined maximum aerosolization temperature.

13. The article of claim 11 , wherein the aerosol-generating element identification device is configured to receive user input regarding the maximum aerosolization temperature of the at least one constituent component of the aerosol-generating element and to communicate the user input maximum aerosolization temperature to the control device, and wherein the control device is configured to modulate the electrical energy provided to the heating element by the power source in response to the user input maximum aerosolization temperature.

14. The article of claim 1 , wherein the aerosol-generating element comprises an annular tobacco plug configured to be removably received within the cavity of the housing.

15. The article of claim 1 , wherein the aerosol-generating element comprises an aerosol-generating liquid received in a cartridge, the cartridge being removably engaged with the housing.

16. The article of claim 14 , wherein an inner surface of the annular tobacco plug extends about the second portion of the heating element and such that the first portion of the heating element extends about an outer surface of the annular tobacco plug within the cylindrical cavity.

17. The article of claim 14 , wherein the housing comprises a removal mechanism configured to remove the annular tobacco plug from within the cavity of the housing.

18. The article of claim 14 , wherein the heating element comprises a resistive coil.

19. The article of claim 14 , wherein the housing is removable from a component housing that includes the power source.
