Abstract

L'invention concerne une tige compressible pour un dispositif de génération d'aérosol qui comprend une première couche et une enveloppe entourant la première couche. La première couche comprend un premier matériau. Le premier matériau peut comprendre du tabac. La tige compressible a une forme de section transversale circulaire et un centre creux. La tige compressible est conçue pour être comprimée, de sorte que la tige compressible a une forme de section transversale non circulaire après compression.
