Definitions

  • Typical aerosol-forming articles are usable in a single usage session. For example, the aerosol-generating article is heated for a predetermined amount of time, or until another usage threshold is met, and then heating may be stopped and the usage session ends. The aerosolgenerating article may be removed from the device and disposed of. To start a new usage session, a user must insert another aerosol-generating article into the aerosol-forming device. This requires a user to carry an aerosol generating device and at least one spare aerosolgenerating article for insertion into the device. Carrying spare aerosol-generating articles and having to remove and insert aerosol-generating articles between each usage session may inconvenience the user.

Abstract

L'invention concerne un produit de génération d'aérosol (100) pour produire un aérosol. Le produit de génération d'aérosol (100) comprend, ou est constitué de, une bande allongée de matériau distribuable (10) définie par une longueur de bande (L), une largeur de bande (W) et une épaisseur de bande (T) initiales. La bande allongée de matériau distribuable (10) comprend un canal d'écoulement d'air initial s'étendant longitudinalement (15) s'étendant entre une extrémité distale (13) et une extrémité proximale (14) de la bande allongée de matériau distribuable (10). La bande allongée de matériau distribuable (10) est conçue pour pouvoir être séparée en une pluralité d'articles de génération d'aérosol discrets (25). Chacun de la pluralité d'articles de génération d'aérosol discrets (25) a une longueur d'article (LA) qui est plus courte que la longueur de bande initiale (L) du matériau distribuable (10) et un canal d'écoulement d'air s'étendant longitudinalement (251). Le canal d'écoulement d'air s'étendant longitudinalement (251) est formé d'une partie du canal d'écoulement d'air initial s'étendant longitudinalement (15) et est défini entre une extrémité distale (231) et une extrémité proximale (241) de l'article de génération d'aérosol discret (25).
