Problems solved by technology

One disadvantage is the possibility of liquid leaking from the liquid reservoir both during transport and storage and when the cartridge is connected to the device part
Using a wick to deliver fluid from the reservoir to the heater can add complexity to the system
Another disadvantage is the increased cost of the cartridge due to the incorporation of a heater inside the cartridge

Embodiment Construction

[0103] figure 1 A cross-sectional view of a cartridge 10 according to one embodiment of the invention is shown. Cartridge 10 includes a container 12 that includes a tubular portion 16 and a base portion 18 that partially defines a cartridge cavity 14 . The outer surface 13 of the container 12 partially defines the outer surface of the cartridge 10 . Positioned within the barrel cavity 14 is a susceptor material 20 having an annular shape having an inner surface 21 and an outer surface 23 that partially define the barrel cavity 14 . The susceptor material 20 comprises a sheet of ferromagnetic stainless steel adhered at its outer surface 23 to the inner surface 25 of the tubular portion 16 of the container 12 . The annular shape of the susceptor material 20 defines a space 27 that can be used as at least one of a mixing chamber and a gas flow channel during use of the cartridge 10 .

[0104] The cartridge 10 also includes a seal 26 extending across the open end of the tubular...

Abstract

There is provided a cartridge (10) for an aerosol-generating system (100), the cartridge (10) comprising a container (12) comprising an outer surface (13) and an inner surface (25), wherein the container outer surface (13) at least partially defines an outer surface of the cartridge (10). The cartridge (10) also comprises a susceptor material (20) comprising a susceptor material inner surface (21)at least partially defining a cartridge cavity (14), the susceptor material inner surface (21) defining a plurality of interstices (22). The cartridge (10) also comprises an aerosol-forming substrate(24) in the form of a gel at room temperature, wherein the gel is positioned within the plurality of interstices (22).

Description

technical field [0001] The present invention relates to a cartridge for an aerosol generating system, the cartridge comprising a susceptor material having an inner surface defining a plurality of gaps. The invention also relates to an aerosol generating system comprising a cartridge and a method of assembling the cartridge. Background technique [0002] Aerosol generating systems, such as electronic cigarettes, which operate by heating a liquid formulation to generate an aerosol for inhalation by a user, are widely used. Typically they comprise device parts and a cartridge. In some systems, the device portion contains the power supply and control electronics, and the cartridge contains a liquid reservoir that holds the liquid formulation, a heater for vaporizing the liquid formulation, and a wick that delivers the liquid from the liquid reservoir to the heater. Despite the popularity of this type of system, it does have several disadvantages. One disadvantage is the possi...
