Abstract
There is provided a filter for a smoking article. The filter comprises a filter segment comprising filter material, and the filter segment has a cross sectional area measured perpendicular to the longitudinal direction of the filter. The filter further comprises a flavour delivery member embedded in the filter segment and surrounded on all sides by the filter material. The flavour delivery member comprises structural material enclosing liquid flavourant for flavouring smoke during smoking of a smoking article provided with the filter, and the flavour delivery member releases at least a portion of the liquid flavourant when the filter is subjected to external force. The cross sectional area of the flavour delivery member measured perpendicular to the longitudinal direction of the filter is about 30% of the cross sectional area of the filter segment or greater.
