Patent

CA 2508710

The present invention relates to a smoking article comprising two layers of wrapper material, the outer wrapper having an air permeability of at least 200 C.U. and having a greater permeability than the inner wrapper. Encapsulated flavour is held between the inner and outer wrappers. The encapsulation technique is dependent upon the flavour to be encapsulated and the sidestream to mainstream flavour delivery ratio required. Sidestream smoke may be altered without altering the mainstream smoke, thereby altering room odours.

L'invention concerne un article pour fumeur comprenant deux couches de matériau d'enveloppe, la couche extérieure présentant une perméabilité à l'air d'au moins 200 C.U. cette perméabilité étant supérieure à celle de la couche d'enveloppe interne. Un arôme encapsulé est retenu entre les enveloppes interne et externe. La technique d'encapsulation dépend de l'arôme à encapsuler et du rapport de diffusion d'arôme entre le courant principal (CP) et le courant secondaire (CS). La fumée du courant secondaire peut être modifiée sans modification de la fumée du courant principal, de manière à modifier les odeurs dans une pièce.
