Abstract

L'invention porte sur une cigarette à filtre comprenant : une tige de cigarette cylindrique pleine (110) ayant une surface d'extrémité avant circulaire (111) et une surface d'extrémité de base circulaire (112) ; et un filtre (120) relié à la tige de cigarette (110). Le filtre (120) a une forme cylindrique pleine obliquement tronquée qui a une surface inférieure (122) ayant la même forme circulaire que la surface d'extrémité de base (112) de la tige de cigarette (110) et qui a également une surface inclinée (121), inclinée par rapport à une ligne s'étendant à partir de l'axe de la tige de cigarette (110). Le filtre (120) est relié à la tige de cigarette (110) au niveau de la surface inférieure (122).
