Abstract

A smoking article component comprising a viscoelastic material (500).

First claim

The invention claimed is:

1. A smoking article component, the smoking article component comprising:
a plug of filter material; and
a viscoelastic tipping material surrounding the plug of filter material, wherein the viscoelastic tipping material comprises a two-ply structure having a first layer and a second layer in which the first layer comprises a paper and the second layer comprises a viscoelastic material, wherein the second layer comprising the viscoelastic material has a thickness between 0.25 mm and 4 mm, and wherein the viscoelastic tipping material is configured to mold around the external shape of an external object when pressure is exerted against the viscoelastic tipping material by the object.

2. The smoking article component according to claim 1 , wherein the viscoelastic tipping material comprises a memory foam.

3. The smoking article component according to claim 1 , wherein the viscoelastic tipping material comprises viscoelastic polyurethane foam.

4. The smoking article component according to claim 1 , wherein the viscoelastic tipping material has a thickness of between 0.5 mm and 2 mm.

5. The smoking article component according to claim 1 , wherein the component is configured to deform upon the application of a force by the external object to provide receiving region in the component, the shape of the receiving region substantially matching the external shape of the object.

6. The smoking article component according to claim 1 , wherein the component comprises a plug wrap surrounding the plug of filter material, wherein the viscoelastic tipping material surrounds the plug wrap.

7. The smoking article component according to claim 1 , wherein the component comprises a tobacco wrap.

8. The smoking article component according to claim 1 , wherein the viscoelastic tipping material is an outermost layer of the component.

9. The smoking article component according to claim 1 , wherein the viscoelastic tipping material is provided around an exterior of the plug of filter material or a plug wrap.

10. The smoking article component of claim 1 , wherein the viscoelastic tipping material forms an outer surface of a filter.

11. The smoking article component of claim 1 , wherein the viscoelastic tipping material is arranged to be in direct contact with the fingers and/or lips of a user during smoking.

12. The smoking article component of claim 1 , wherein the second layer is provided on an outer surface of the first layer.

13. A smoking article comprising the smoking article component according to claim 1 .

14. A method comprising providing a viscoelastic tipping material in a smoking article component, the viscoelastic tipping material comprising a two-ply structure having a first layer and a second layer in which the first layer comprises a paper and the second layer comprises a viscoelastic material, wherein the second layer comprising the viscoelastic material has a thickness between 0.25 mm and 4 mm.
