Abstract

A smoking article, a smoking article assembly, a blank for forming a smoking article, and a method of manufacturing a smoking article. A smoking article comprising one or more rod articles, an inner layer extending around the rod articles, and an outer layer extending around the inner layer. The inner and outer layers are integrally formed. The outer layer comprises a selection portion configured to move over an underlying part of the inner layer to select a property of the smoking article.

First claim

The invention claimed is:

1. A smoking article, comprising:
one or more rod articles;
an inner layer disposed around the one or more rod articles; and
an outer layer disposed around the inner layer,
wherein the inner and outer layers are integrally formed, the outer layer including a selection portion configured to be moved relative to an underlying part of the inner layer to select a property of a smoking article.

2. The smoking article as claimed in claim 1 , wherein the selection portion of the outer layer defines a cut-out area adjacent to the inner layer and is configured such that the selection portion is movable towards the inner layer from an initial position.

3. The smoking article as claimed in claim 1 , further comprising:
a limiter configured to limit movement of the selection portion, wherein the limiter couples the selection portion to the underlying part of the inner layer.

4. The smoking article as claimed in claim 1 , wherein one of the outer layer and the inner layer defines a slot, and the other of the outer layer and the inner layer is attached to a limiter element moveable within the slot to limit movement of the selection portion.

5. The smoking article as claimed in claim 1 , wherein the selection portion of the outer layer is frangibly connected to a further part of the outer layer, and/or the underlying part of the inner layer is frangibly connected to a further part of the inner layer.

6. The smoking article as claimed in claim 1 , wherein the inner layer comprises includes a first ventilation area, the outer layer comprises a second ventilation area movable relative to the first ventilation area, and an overlapping area of the first ventilation area and the second ventilation area determines a ventilation of the smoking article.

7. The smoking article as claimed in claim 4 , wherein the inner layer includes a first ventilation area, the outer layer includes a second ventilation area movable relative to the first ventilation area, and an overlapping area of the first ventilation area and the second ventilation area determines a ventilation of the smoking article, wherein the slot defines one of the first ventilation area or the second ventilation area.

8. The smoking article as claimed in claim 1 , wherein the outer layer includes a forward part and a rearward part longitudinally rearward of the forward part, the selection portion disposed at an interface between the forward part and the rearward part.

9. The smoking article as claimed in claim 8 , wherein the forward part is frangibly connected to the rearward part and configured to detach from the rearward part on application of a force.

10. The smoking article as claimed in claim 1 , further comprising an indexing mechanism configured to index movement between the outer layer and the one or more rod articles.

11. A smoking article assembly for forming two smoking articles, the smoking article assembly comprising:
rod articles for forming the smoking articles;
an inner layer disposed around the rod articles; and
an outer layer disposed around the inner layer,
wherein the inner and outer layers are integrally formed, the outer layer including a selection portion for each smoking article, each said selection portion configured to move over a corresponding underlying part of the inner layer to select a property of a smoking article, the smoking article assembly configured to be cut into two separate smoking articles.

12. The smoking article assembly as claimed in claim 11 , wherein the inner and outer layers are configured such that the selection portion for each of the two smoking articles is rotatable in a same sense on each of the two separate smoking articles, once separated.

13. The smoking article assembly as claimed in claim 11 , wherein at least one selection portion of the outer layer defines a cut-out area adjacent to the inner layer, wherein said cut-out area is configured such that the selection portion is movable towards the inner layer from an initial position.

14. The smoking article assembly as claimed in claim 11 , further comprising a limiter for each smoking article, configured to limit movement of the corresponding selection portion, wherein each said limiter couples the corresponding selection portion for the respective smoking article to the corresponding underlying part of the inner layer, and is configured such that the selection portion for each of the two smoking articles is rotatable in a same sense on the two separate smoking articles, once separated.

15. The smoking article assembly as claimed in claim 14 , wherein each limiter of each of the two separate smoking articles, once separated, comprises:
a slot on one of the outer layer and the inner layer, and
a limiter element, attached to the other of the outer layer and the inner layer and located within the slot, the limiter element moveable to limit movement of the corresponding selection portion,
wherein the limiter element is initially disposed, at an end of its corresponding slot and arranged such that the two smoking articles are rotatable in a same sense when separated.

16. A blank for wrapping around one or more rod articles to form a smoking article, the blank comprising:
a first area configured to form an inner layer extending around one or more rod articles,
a second area configured to form an outer layer extending around the inner layer,
wherein the first and second areas are integrally formed, and the second area defines a selection portion configured to move over an underlying part of the inner layer to select a property of a smoking article.

17. The blank as claimed in claim 16 , wherein the selection portion of the second area defines a cut-out area adjacent to the first area and configured such that the selection portion is movable towards the inner layer from an initial position when wrapped around the rod articles.

18. The blank as claimed in claim 16 , wherein the blank is configured to wrap around the one or more rod articles to form two smoking articles, the first area includes a selection portion, for each smoking article, configured to move over a corresponding underlying part of the inner layer to select a property of the corresponding smoking article, and the blank is configured to be cut into two sections to define two separate smoking articles.

19. The blank as claimed in claim 18 , further comprising a limiter configured to limit movement of the selection portion of each smoking article, wherein the limiter is configured to couple the selection portion of each smoking article to the corresponding underlying part of the inner layer, and the limiter is configured such that the selection portion of each of the two smoking articles is rotatable in a same sense on the two smoking articles, once assembled and separated.

20. The blank as claimed in claim 19 , wherein the limiter comprises:
a slot on one of the outer layer and the inner layer for each smoking article, and
a limiter element attached to the other of the outer layer and the inner layer, configured to be located within the slot for each smoking article and moveable to limit movement of the corresponding selection portion,
wherein the limiter element is configured to be initially disposed at an end of its corresponding slot and configured such that the two smoking articles are rotatable in a same sense on the two smoking articles, once assembled and separated.

21. A method of manufacturing a smoking article, the method comprising:
providing one or m
