Abstract

A smoking article includes identification information encoded on the smoking article. The smoking article can be used with an electrically heated smoking system having a detector for detecting the smoking article and distinguishing the smoking article from other articles based on the identification information. A cleaning article includes identification information encoded on the cleaning article. The cleaning article cleans an electrically heated smoking system having a detector for detecting the cleaning article and distinguishing the cleaning article from other articles based on the identification information. An electrically heated smoking system for receiving an article configured for use with the smoking system includes: a cavity for receiving the article having identification information encoded thereon, a heating element, a power supply, electrical hardware, and a detector capable of detecting the presence of the article in the cavity and distinguishing the article from other articles based on the identification information.

First claim

We claim:

1. A smoking system comprising:
a smoking article including,
a tubular body,
an aerosol-forming substrate, the aerosol-forming substrate including reconstituted tobacco,
encoded identification information, and
usage information, the usage information indicating whether the smoking article has been used, the usage information being separate from the encoded identification information; and

a detector configured to detect a presence of the article in the system and distinguish the article among the other articles configured for use with the smoking system, based on the encoded identification information and the usage information.

2. The smoking system of claim 1 , wherein the encoded identification information is printed on the smoking article.

3. The smoking system of claim 1 , wherein the encoded identification information includes at least one of visible ink, ultra violet (UV) ink, infrared (IR) ink, phosphorescent ink, fluorescent ink, metallic ink, a sub-combination thereof or a combination thereof.

4. The smoking system of claim 1 , wherein the encoded identification information identifies at least one of smoking article type, aerosol-forming substrate type, cleaning article type, cleaning means information, cleaning ingredient type, date of production, place of production, production batch number, production details, use-by date, a sub-combination thereof or a combination thereof.

5. The smoking system of claim 1 , wherein the encoded identification information includes a plurality of lines having spaces therebetween, each of the plurality of lines representing a first value and each of the spaces representing a second value, the first value and the second value being different.

6. The smoking system of claim 5 , wherein the first value and the second value are binary values.

7. The smoking system of claim 5 , wherein the plurality of lines are circular.

8. The smoking system of claim 1 , wherein the encoded identification information includes at least a first line and a second line, the first line having a first width and the second line having a second width, the first width and the second width being different.

9. The smoking system of claim 8 , wherein the first line represents a first value and the second line represents a second value, the first value and the second value being different.

10. The smoking system of claim 9 , wherein the first value and the second value are binary values.

11. The smoking system of claim 8 , wherein the first line and the second line are circular.

12. The smoking system of claim 1 , wherein the usage information includes a thermally sensitive ink that changes when heated at a noncombustible temperature.
