Abstract

L'invention concerne une cigarette à filtre qui permet d'empêcher la contamination de fumée de tabac avec des matières étrangères telles que des pollens tout en garantissant une bonne circulation d'air, et qui permet aussi d'empêcher l'exsudation d'un agent aromatisant libéré de capsules ayant l'agent aromatisant encapsulé en son sein vers le côté papier à copeaux quand les capsules sont incluses dans un filtre de cigarette ; un filtre de cigarette, et un papier enveloppe destiné à être utilisé dans un filtre de cigarette. Une cigarette à filtre (1) est pourvue d'une partie tabac (2) qui est construite en enveloppant des bandes de feuille de tabac (21) par un papier en rouleau (22) et une partie filtre (3) qui est reliée à une extrémité de la partie tabac et qui comporte des matériaux filtrants (41, 42), la partie filtre comportant des morceaux de papier enveloppe (51, 52), chacun de ces derniers enveloppant les matériaux filtrants et étant fabriqué à partir d'une feuille de nanofibre.
