SMOKING ARTICLE FILTER HAVING LIQUID ADDITIVE CONTAINING TUBES THEREIN

摘要

Provided are filters (14) including at least one impervious additive containing tube (24). A barrier layer (28), such as a liquid barrier layer (28), seals each end of the tube (24) so as to contain additives, such as a liquid additive (26), within the additive containing tube (24). The one or more additive containing tubes (24) are inserted into filters (14) for smoking articles (10). Drawing action during a puff causes breach of the barrier layer (28) and release of the additive (26) into the surrounding filter material (36).
