1. An aerosol-generating system comprising:
an aerosol-generating article comprising:
an aerosol-forming substrate comprising homogenized tobacco material and an aerosol-former, the aerosol-forming substrate being molded to form the aerosol-generating article, the aerosol-generating article being a hollow frustum with an open base, a closed top, and a conical side wall, and an interior face and an exterior face of the side wall have a corresponding shape and orientation, wherein the conical side wall and the closed top of the aerosol-generating article are formed by the aerosol-forming substrate,
wherein a wrapping material covers the interior face of the side wall of the aerosol-generating article serving as an interface between the aerosol-forming substrate and a heating element of the aerosol-generating device, and
wherein a wrapping material covers the exterior face of the side wall, and the wrapping material that covers the interior face of the side wall and the wrapping material that covers the exterior face of the side wall are made of a same material; and
an electronic aerosol-generating device comprising a mouthpiece and a device housing, the device housing comprising a heating element having a shape comprising a frustum,
wherein the aerosol-generating article is mounted to the heating element with the interior face of the side wall of the aerosol-generating article having a corresponding shape and orientation with a lateral surface area of the frustum of the heating element, thereby forming a close contact between the heating element and the aerosol-generating article, and with the wrapping material covering the interior face of the side wall of the aerosol-generating article serving as an interface between the aerosol-forming substrate and the heating element,
wherein a height of the heating element corresponds to a height of the aerosol-generating article, and
wherein the mouthpiece comprises an internal conical wall, and the internal conical wall of the mouthpiece and the lateral surface area of the frustum of the heating element have a corresponding shape and orientation,
wherein the wrapping material on the exterior face of the side wall is immediately adjacent to the internal conical wall of the mouthpiece.
