Abstract

An aerosol-generating article includes a charge of aerosol-generating material arranged in a container, wherein the aerosol-generating material is provided in a form of shaped individual elements including a foam-like material. The aerosol-generating article further includes a sealing portion provided to one longitudinal end of the container, and made of an air permeable material and/or having an air permeable structure such that air is capable of flowing therethrough.

First claim

The invention claimed is:

1 . An aerosol-generating article, comprising:
a plurality of containers each housing a charge of aerosol-generating material in a form of a shaped individual element comprising a foam material, and a sealing portion provided to one longitudinal end of the plurality of containers, and made of an air permeable material and/or having an air permeable structure such that air is capable of flowing therethrough, wherein the plurality of containers and the sealing portion are attached in abutment together by one or several wrappers to form an elongated, substantially cylindrical structure.

2 . The aerosol-generating article according to claim 1 , wherein each container is distinct from the sealing portion and is air permeable.

3 . The aerosol-generating article according to claim 2 , wherein each container is distinct from the sealing portion and comprises an air permeable material and/or an air permeable structure.

4 . The aerosol-generating article according to claim 1 , wherein the air permeable material is at least one of cellulose acetate, paper, metal, heat resistant plastic, activated charcoal, or a combination thereof.

5 . The aerosol-generating article according to claim 1 , wherein the aerosol-generating material comprises a tobacco originating agent having a weight of 0.1 66 wt. % of a weight of the foam material.

6 . The aerosol-generating article according to claim 5 , wherein the tobacco originating agent is at least one of tobacco, tobacco flavour, nicotine, or derivatives of nicotine.

7 . The aerosol-generating article according to claim 1 , wherein the aerosol-generating material further comprises an aerosol-forming agent, a foam-stabilizing agent, and a foam-forming agent, wherein the aerosol-forming agent has a weight of 10-80 wt. % of a weight of the foam material.

8 . The aerosol-generating article according to claim 1 , wherein each container comprises a tubular wall made of a material, wherein the material is at least one of paper, metal, plastic, silica or a combination thereof.

9 . The aerosol-generating article according to claim 1 , wherein each container is filled up to at most 95% of a space therein.

10 . The aerosol-generating article according to claim 1 , wherein the shaped individual elements of the aerosol-generating material are in a form of pods, granules, elongated fibres, elongated spirals or a combination thereof.

11 . The aerosol-generating article according to claim 10 , wherein the shaped individual elements of the aerosol-generating material together comprise a bundle of elongated fibres, wherein each elongated fibre has an average diameter of between 0.3 and 5 mm.

12 . The aerosol-generating article according to claim 1 , further comprising a filter attached at a longitudinal end of the plurality of containers.

13 . The aerosol-generating article according to claim 12 , wherein the filter comprises cellulose acetate, paper, heat resistant plastic or polymer, activated charcoal, a flavourant, or a combination thereof.

14 . The aerosol-generating article according to claim 1 , wherein the sealing portion is provided with gel, silica, gum, slurry, or matrix.

15 . The aerosol-generating article according to claim 3 , wherein each container comprises the air permeable structure, and the air permeable structure is micro holes or mesh.

16 . The aerosol-generating article according to claim 1 , wherein the aerosol-generating material further comprises an aerosol-forming agent, a foam-stabilizing agent, and a foam-forming agent, wherein the aerosol-forming agent has a weight of 30-70 wt. % of a weight of the foam material.

17 . The aerosol-generating article according to claim 1 , wherein one or more airflow channels are arranged longitudinally in a longitudinal direction of the aerosol-generating article between the shaped individual elements.

18 . The aerosol-generating article according to claim 1 , wherein 30% of the space of an aerosol-generating material portion housing the plurality of containers is unfilled.

19 . An aerosol-generating article, comprising:
a plurality of containers each housing a charge of aerosol-generating material in a form of a shaped individual element comprising a foam material, and a sealing portion provided to one longitudinal end of the plurality of containers, and made of an air permeable material and/or having an air permeable structure such that air is capable of flowing therethrough, wherein the plurality of containers each housing the charge of aerosol-generating material forms an aerosol-generating material portion, and wherein the sealing portion, the aerosol-generating material portion, and a mouthpiece portion of the aerosol-generating article are attached in abutment together by one or several wrappers.
