Abstract
A smoking article is formed from two component parts. These parts are a rod comprising an aerosol-forming substrate and a removable cap. The removable cap can be coupled to the rod in two configurations. In a first configuration, the removable cap is coupled to a first end of the rod and a heat source located at or near a second end of the rod heats the aerosol-forming substrate to generate an inhalable aerosol. In a second configuration, the removable cap is coupled to the second end of the rod and at least substantially covers the heat source. The smoking article is arranged in the second configuration for disposal.

-15. (canceled)
A smoking article, comprising:
- a rod having a first end and a second end;
- a combustible heat source located at or proximate to the second end of the rod;
- and
- a removable cap, the removable cap being removably couplable to both the first end and the second end of the rod,
- wherein in a first configuration of the smoking article the removable cap is coupled to the first end of the rod such that air may be drawn from the rod through the removable cap,
- wherein in a second configuration of the smoking article the removable cap is coupled to the second end of the rod such that the second end is at least substantially covered by the removable cap, such that in the second configuration the removable cap facilitates disposal of the smoking article after use, and
- wherein the removable cap comprises a thermally insulating material to thermally isolate the combustible heat source when the removable cap is coupled to the second end of the rod.
A removable cap for a smoking article, wherein the cap is removably couplable to both a first end and a second end of a rod comprising an aerosol-forming substrate to form the smoking article, in which the cap is configured such that when coupled to the first end of the rod air may be drawn from the rod through the cap, and when coupled to the second end of the rod, the cap facilitates disposal of the smoking article after use of the smoking article.
Use of the removable cap according to claim 8 as a mouthpiece when coupled to a first end of a rod comprising an aerosol-forming substrate, and as a means to facilitate disposal of the rod when coupled to a second end of the rod after use.
The removable cap according to claim 8, further comprising a thermochromatic material or pigment.
A method of using a smoking article comprising a rod having a first end and a second end, and a removable cap coupled to the first end of the rod, the method comprising:
- applying a source of heat to the second end of the rod;
- drawing air from the rod through the removable cap;
- removing the removable cap from the first end of the rod;
- and
- coupling the removable cap to the second end of the rod such that the second end of the rod is at least substantially covered by the removable cap.
A method of facilitating disposal of a smoking article comprising a rod comprising a heat source and an aerosol-forming substrate after use, the method comprising providing a removable cap that is removably couplable to a first end of the rod such that air may be drawn from the rod through the cap, and removably couplable to a second end of the rod such that the heat source is at least substantially covered by the removable cap.
