Abstract
The present disclosure provides a smoking article comprising a combustible heat source, comprising: a first part containing a combustible heat source; a second part containing a tobacco material; an airflow hole extending to the upstream side of the combustible heat source from the downstream side end of the first part; and a buffer space located between the first part and the second part and connected to the airflow hole, wherein the airflow hole does not penetrate the combustible heat source. The smoking article has an effect of improving combustion persistency by using a combustible heat source to which an airflow hole is applied.
Claims8
A smoking article comprising a combustible heat source, comprising:
- a first part containing a combustible heat source;
- a second part containing a tobacco material;
- a thermally conductive wrapper surrounding the first part and the second part;
- an airflow hole extending toward the upstream side of the combustible heat source from the downstream side end of the first part;
- a buffer space located between the first part and the second part and connected to the airflow hole, and
- an outer cigarette paper surrounding the smoking article comprising the combustible heat source,
- wherein the airflow hole does not penetrate the combustible heat source,
- wherein the combustible heat source is not penetrated,
- wherein the depth of the airflow hole has a length of 50 to 70% of the length of the combustible heat source, and
- wherein the thermally conductive wrapper and an outer circumferential surface of the outer cigarette paper include one or more perforations thereof.
