Abstract: The invention relates to a battery module for an aerosol generating system. It comprises a battery extending substantially in a longitudinal direction and a printed circuit board assembly connected to the battery. The battery comprises along the longitudinal direction a first portion of a first thickness, and a second portion comprising opposite faces defining a second thickness, the second thickness being less than the first thickness. The printed circuit board assembly is electrically connected to the second portion of the battery on one of said opposite faces. This allows spatial optimization of the battery module. The invention also relates to a corresponding aerosol generating system, and to a corresponding set comprising a battery charger.

Abstract: An aerosol generation system comprises a consumable and an aerosol generation device. The consumable comprises a housing configured to contain an aerosol generating material, the housing having a first surface configured to engage with the aerosol generation device. The first surface comprises a breakable material configured to be broken upon interaction with piercing elements of the aerosol generation device, and a protective barrier configured to be resistant to the piercing elements. The breakable material and the protective barrier are arranged such that the protective barrier defines breakable regions in the first surface. The aerosol generation device comprises piercing elements arranged to pierce cooperating breakable regions in the first surface of the consumable, and to be inhibited from piercing a protective barrier in the first surface of the consumable.
