Abstract

A smoking article, especially a smoking article in the form of a replaceable cartridge, pellet, or capsule for a water-pipe, includes a body of smoking material, such as tobacco or the like, and a heat source provided in the body for heating the smoking material, wherein the smoking article defines an airflow path for air to be heated by the heat source and to pass through the body of smoking material.

First claim

1 . A smoking article, comprising:
a body of smoking material; and a heat source provided or embedded in the body for heating the body of smoking material; wherein the smoking article defines an airflow path for air to be heated by the heat source and to pass through the body of smoking material.

2 . The smoking article according to claim 1 , wherein the heat source has at least one element for heating air on the airflow path, wherein the element includes one or more channels for flow of air there-through, the one or more channels forming a part of said airflow path.

3 . The smoking article according to claim 1 , wherein the body of smoking material includes at least one baffle member for directing airflow through the body of smoking material along the airflow path.

4 . The smoking article according to claim 1 , wherein the heat source is physically separated from the body of smoking material by a barrier layer.

5 . The smoking article according to claim 1 , wherein an air chamber is arranged in the air-flow path between the heat source and the body of smoking material.

6 . The smoking article according to claim 5 , wherein the air chamber is located below and/or laterally of the heat source and is in fluid communication with the body of smoking material.

7 . The smoking article according to claim 5 , wherein the body of smoking material includes at least one baffle member for directing airflow from the air chamber in a convoluted manner along the airflow path through the body of smoking material.

8 . The smoking article according to claim 1 , wherein the heat source is substantially surrounded or encompassed by the body of smoking material.

9 . The smoking article according to claim 1 , wherein the heat source is substantially centrally located in the body of smoking material.

10 . The smoking article according to claim 1 , wherein the body of smoking material is wrapped or covered with a protective barrier layer or film.

11 . The smoking article according to claim 1 , wherein an outer end region of the element of the heat source includes a cover or screen to prevent direct contact therewith by a user, the cover or screen including holes or apertures forming part of the airflow path.

12 . The smoking article according to claim 1 , wherein the heat source includes at least one heat transfer member that extends from the element into the body of smoking material for conducting heat thereto.

13 . The smoking article according to claim 1 , wherein the smoking article is formed as a cartridge, pellet or capsule.

14 . The smoking article according to claim 1 , wherein the body of smoking material comprises tobacco.

15 . The smoking article according to claim 2 , wherein the at least one element for heating air on the airflow path includes a fuel element.

16 . The smoking article according to claim 4 , wherein the barrier layer comprises an aluminum foil.

17 . The smoking article according to claim 6 , wherein the air chamber is in fluid communication with the body of smoking material via perforations or holes in a barrier layer.

18 . The smoking article according to claim 9 , wherein the body of smoking material is substantially cylindrical in shape.

19 . The smoking article according to claim 10 , wherein the protective barrier layer or film comprises a metal foil, and optionally an outer thermally insulating layer, such as paper.

20 . The smoking article according to claim 11 , further comprising an outer thermally insulating layer, such as paper.

21 . The smoking article according to claim 20 , wherein the outer thermally insulating layer comprises paper.

22 . The smoking article according to claim 12 , wherein the at least one heat transfer member comprises a fin or a plate.
