Method for providing an aerosol-generating device, aerosol-generating device and flat aerosol-generating article for use in such a device

Aerosol-generating device comprising a device housing comprising a moulding cavity for receiving an aerosol-forming substrate,

• the moulding cavity at least partially corresponds to a moulding space between a first and a second mould half of a mould, the first mould half and the second mould half being internal surfaces of the device housing,
• wherein in an open state of the mould corresponding to an open device housing, the aerosol-generating device is adapted to receive a flat aerosol-forming substrate in between the first and second mould halves,
• wherein in a closed state of the mould corresponding to a closed device housing, the moulding space in between the first and second mould halves has a non-flat shape, wherein the first and second mould halves are adapted to transform a flat aerosol-forming substrate supplied between the first and second mould halves into a non-flat aerosol-forming substrate having a shape corresponding to the non-flat moulding space in the mould upon closing of the mould.

Flat aerosol-generating article for use in an aerosol-generating device, the flat aerosol-generating article comprising an aerosol-forming substrate and having an at least partially convex circumference, the flat aerosol-generating article being transformable into a conical shape.

Kit for an aerosol-generating system, the kit comprising:

• an aerosol-generating device comprising a device housing comprising a moulding cavity, the moulding cavity at least partially corresponding to a moulding space between a first and a second mould half of a mould, the first mould half and the second mould half being internal surfaces of the device housing, the mould having a longitudinal mould extension and a lateral mould extension;
• a flat aerosol-generating article comprising a flat aerosol-forming substrate having a longitudinal substrate extension and a lateral substrate extension,
• wherein the flat aerosol-generating article is configured to be mounted in the moulding cavity in between the first and second mould half of the device housing, and is configured to be transformed into a non-flat aerosol-forming substrate having a shape corresponding to the non-flat moulding space in the mould upon closing of the mould, and wherein the lateral substrate extension is larger than the lateral mould extension or wherein the longitudinal substrate extension is larger than the longitudinal mould extension.
