Problems solved by technology

However, at room temperature, the vapor pressure of pyruvate is substantially greater than that of nicotine, resulting in a difference in the vapor concentrations of the two agents
The difference between the volatile delivery-enhancing compound and the vapor concentration of nicotine in devices of the type disclosed in WO 2008 / 121610 A1, WO 2010 / 107613 A1 and WO 2011 / 034723 A1 can detrimentally lead to unreacted delivery Enhances compound vapor delivery to the user

Embodiment Construction

[0169] figure 1 An aerosol-generating system comprising an aerosol-generating article 2 and an aerosol-generating device 4 according to a first embodiment of the invention is schematically shown.

[0170] The aerosol-generating article 2 has an elongated cylindrical shape and comprises a housing comprising a first compartment 6 comprising a volatile delivery compartment 6, a second compartment 8 and a third compartment 10. To enhance the source of compounds, the second compartment 8 includes a source of nicotine. like figure 1 As shown in , the first compartment 6, the second compartment 8, and the third compartment 10 are arranged consecutively and coaxially aligned within the aerosol-generating article 2. The first compartment 6 is positioned at the distal or upstream end of the aerosol-generating article 2 . The second compartment 8 is positioned immediately downstream of and adjoins the first compartment 6 . The third compartment 10 is positioned downstream of the seco...

Abstract

An aerosol-generating system comprises an aerosol-generating article (2) and an aerosol-generating device (4). The aerosol-generating article (2) comprises: a first compartment (6) comprising a first one of a volatile delivery enhancing compound source and a medicament source; and a second compartment (8) comprising a second one of the volatile delivery enhancing compound source and the medicament source. The aerosol-generating device (4) comprises: a cavity configured to receive the first compartment (6) and the second compartment (8) of the aerosol-generating article (2); and an external heater (16, 16a, 16b) positioned about a perimeter of the cavity. The aerosol-generating device (4) is configured to heat the first compartment (6) and the second compartment (8) of the aerosol-generating article (2) so that first compartment (6) of the aerosol-generating article (2) has a lower temperature than the second compartment (8) of the aerosol-generating article (2).

Description

technical field [0001] The present invention relates to an aerosol generating system and an aerosol generating device for use in an aerosol generating system. In particular, the present invention relates to an aerosol-generating system for generating an aerosol comprising nicotine salt particles and an aerosol-generating device for use in such an aerosol-generating system. Background technique [0002] WO 2008 / 121610 A1, WO 2010 / 107613 A1 and WO 2011 / 034723 A1 disclose devices for delivering nicotine or other agents to a user, including volatile acids such as pyruvate, or Other volatile sources of delivery enhancing compounds and sources of nicotine or other pharmaceutical agents. The volatile delivery-enhancing compound reacts with the nicotine in the gas phase to form an aerosol of nicotine salt particles that is inhaled by the user. [0003] At room temperature, both pyruvate and nicotine are sufficiently volatile to form respective vapors that react with each other in ...
