Abstract
Official abstract text for this publication.
There is provided a smoking article ( 10 ) comprising: a tobacco rod ( 12 ) comprising a charge ( 16 ) of tobacco material circumscribed by a wrapper ( 18 ); a filter ( 14 ) arranged downstream of the tobacco rod ( 12 ); and a hollow tube ( 20 ) defining an inner cavity ( 22 ) and attaching the filter ( 14 ) to the tobacco rod ( 12 ). An affixing portion ( 24 ) of the tobacco rod ( 12 ) is received within the inner cavity ( 22 ) and secured to the hollow tube ( 20 ) by means of a thermally deactivatable adhesive ( 26 ) provided on an outer surface of the wrapper ( 18 ) or on an inner surface of the hollow tube ( 20 ) or on both. Thus, upon deactivation of the adhesive, at least a portion of the tobacco rod ( 12 ) becomes slidable within the hollow tube ( 20 ) in relation to the filter ( 14 ).

A smoking article comprising: a tobacco rod comprising a charge of tobacco material circumscribed by a wrapper; a filter arranged downstream of the tobacco rod; a hollow tube defining an inner cavity and attaching the filter to the tobacco rod; wherein an affixing portion of the tobacco rod is received within the inner cavity and secured to the hollow tube by means of a thermally deactivatable adhesive provided on an outer surface of the wrapper or on an inner surface of the hollow tube or on both such that, upon deactivation of the adhesive, at least a portion of the tobacco rod becomes slidable within the hollow tube in relation to the filter. 2. The smoking article according to claim 1 , wherein a length of the tobacco rod is less than about 40 millimetres. 3. The smoking article according to claim 1 , wherein a length of the tobacco rod is at least about 10 millimetres. 4. The smoking article according to claim 1 , wherein the length of the affixing portion of the tobacco rod is at least about 1 millimetre. 5. The smoking article according to claim 1 , wherein the length of the affixing portion of the tobacco rod is less than about 10 millimetres. 6. The smoking article according to claim 1 , wherein the tobacco rod comprises tobacco cut filler. 7. The smoking article according to claim 1 , wherein the tobacco rod comprises crimped reconstituted tobacco. 8. The smoking article according to claim 1 , wherein the thermally deactivatable adhesive is provided over an affixing area of the outer surface of the wrapper or of the inner surface of the hollow tube or of both, the affixing area extending circumferentially about the tobacco rod. 9. The smoking article according to claim 1 , wherein the thermally deactivatable adhesive is provided over the outer surface of the wrapper or of the inner surface of the hollow tube or of both in a pattern spiralling about the tobacco rod. 10. The smoking article according to claim 1 comprising a ventilation zone at a location along the filter. 11. The smoking article according to claim 1 comprising a ventilation zone at a location along the hollow tube. 12. The smoking article according to claim 1 , wherein an adhesive force of the adhesive following deactivation is less than about 0.15 Newtons. 13. The smoking article according to claim 1 , wherein an adhesive force of the adhesive prior to deactivation is at least about twice the adhesive force of the adhesive following deactivation. 14. The smoking article according to claim 1 , wherein the adhesive has a deactivation temperature of less than about 120 degrees Celsius. 15. The smoking article according to claim 1 , wherein the adhesive has a deactivation temperature of less than about 90 degrees Celsius.
