Definitions

• Aerosol generating device comprising a supporting structure receiving heating plates
• a commonly available reduced-risk or modified-risk device is the heated substrate aerosol generation device or heat-not-burn device.
• Devices of this type generate aerosol or vapour by heating an aerosol substrate that typically comprises moist leaf tobacco or other suitable vaporizable material to a temperature typically in the range 150°C to 350°C. Heating an aerosol substrate, but not combusting or burning it, releases aerosol that comprises the components sought by the user but not the toxic and carcinogenic byproducts of combustion and burning.
• an aerosol generating device generally encloses at least one heating plate intended to heat an aerosol substrate. During operation, a heat transfer occurs between the heating plate and the aerosol substrate, but also with other internal components of the aerosol generating device as for example means supporting the heating plate. Hence, heat is dissipated in the aerosol generating device through said supporting means. Energy is lost and autonomy is limited.
• the tobacco article may be a flat-shaped cuboid, for example extending along a substrate axis X.
• both retention sides of each recess portion are inclined in respect with the transversal axis.
• FIG. 6 is an enlarged view of a part of Figure 5;
• vaporizable material may refer to a smokable material which may for example comprise nicotine or tobacco and an aerosol former.
• tobacco may take the form of various materials such as shredded tobacco, granulated tobacco, tobacco leaf and/or reconstituted tobacco.
• Suitable aerosol formers include: a polyol such as sorbitol, glycerol, and glycols like propylene glycol or triethylene glycol; a non-polyol such as monohydric alcohols, acids such as lactic acid, glycerol derivatives, esters such as triacetin, triethylene glycol diacetate, triethyl citrate, glycerin or vegetable glycerin.
• the mouthpiece part 16 defines a plurality of venting holes 22 arranged for example according to the whole perimeter of the mouthpiece part 16 along two axes perpendicular to the substrate axis X.
• the venting holes 22 are arranged on each wall of the substrate among the substrate side walls 13A, 13B and the substrate contact walls 14A, 14B.
• the venting holes 22 are arranged only on the substrate contact walls 14A, 14B or preferably, only on one of the substrate contact walls 14A, 14B.
• the venting holes 22 may be aligned perpendicularly to the substrate axis on the or each corresponding wall of the substrate 12, and can be spaced by a same distance.
• the venting holes 22 allow fresh air entering inside the substrate 12 to achieve particular vaping/tasting effects.
• the housing 34 may for example form a substantially rectangular shape with rounded edges.
• the housing 34 with the mouthpiece 32 form at least four outer walls 40.
• the housing 34 can have a round cross-sectional shape. In this case, it can form with the mouthpiece 32 only one outer wall 40.
• the housing 34 can be sealed at the end opposite to the insertion opening 36 receiving the mouthpiece 32.
• the housing 34 can be formed from a single piece or several assembled pieces made of any suitable material like aluminium or plastic.
• the material of the housing 34 can be a thermally conductive material. In some other embodiments, it can be a thermally insulating material.
