Abstract

The aerosol-generating article for use with an aerosol-generating device, the aerosol-generating article comprises an aerosol-forming substrate, and a surface area comprising a three dimensional code. The invention also relates to an aerosol-generating system comprising an aerosol-generating device and an aerosol-generating article.

First claim

The invention claimed is:

1. An aerosol-generating article for use with an aerosol-generating device, the aerosol-generating article comprising:
an aerosol-forming substrate, and
a surface area comprising a three dimensional code,
wherein the three dimensional code comprises pits and lands, and wherein the aerosol-generating article has a flat shape, and the three dimensional code is provided on or in a reflective surface.

2. An aerosol-generating article according to claim 1 , wherein the three dimensional code is provided in a form of a sticker or a wrapper attached to the aerosol-generating article.

3. An aerosol-generating article according to claim 1 , wherein the three dimensional code is readable by optical or mechanical means.

4. An aerosol-generating article according to claim 1 , wherein the three dimensional code is covered by transparent, protective material.

5. An aerosol-generating article according to claim 1 , wherein the three dimensional code is provided at a single area of the aerosol-generating article.

6. An aerosol-generating article according to claim 1 , wherein the three dimensional code is provided in a form of a wrapper attached to the aerosol-generating article, wherein the wrapper is formed from a layered structure.

7. An aerosol-generating device comprising:
a cavity for at least partially receiving the aerosol-generating article according to claim 1 ;
a detector capable of reading the three dimensional code of the aerosol-generating article.

8. An aerosol-generating device according to claim 7 , wherein the detector for reading the three dimensional code comprises optical means for reading the three dimensional code.

9. An aerosol-generating device according to claim 8 , wherein the optical means for reading the three dimensional code comprises a radiation source.

10. An aerosol-generating device according to claim 9 , wherein the optical means for reading the three dimensional code further comprises at least one mirror and an optical receiver, and wherein the at least one mirror is configured to direct the radiation onto the three dimensional code, and wherein the optical receiver is configured to receive radiation reflected from the three dimensional code.

11. An aerosol-generating device according to claim 9 , wherein the radiation source is also configured for heating the aerosol-forming substrate of the aerosol-generating article.

12. An aerosol-generating system comprising:
an aerosol-generating device according to claim 7 ; and
an aerosol-generating article comprising:
an aerosol-forming substrate, and
a surface area comprising a three dimensional code,

wherein the three dimensional code comprises pits and lands, and wherein the aerosol-generating article has a flat shape, and the three dimensional code is provided on or in a reflective surface.
