Embodiment Construction

[0119] The same reference numerals will be used to denote the same components in the following description of the figures.

[0120] figure 1 There are shown first and second consumable parts of an aerosol-generating article according to a first embodiment of the present invention. The first consumable part 10 comprises a tubular section 12 sealed at both ends by frangible barriers 14 and 16 formed of metal foil. A medicament source 18 is mounted on the inner surface of the tubular section 12 and includes a medicament, such as nicotine, adsorbed on the porous adsorbent element.

[0121] Similarly, the second consumable part 20 comprises a tubular section 12 sealed at both ends by frangible barriers 14 and 16 . A volatile delivery-enhancing compound source 22 is mounted on the inner surface of the tubular section 12 and includes a volatile delivery-enhancing compound, such as pyruvate, adsorbed on a porous adsorbent element.

[0122] like figure 2 As shown, first and second...

Abstract

The present invention provides an aerosol-generating system (80) comprising an aerosol-generating device (70) including a heater element (72), and an aerosol-generating article (60). The aerosol-generating article (60) includes a source (18) of a medicament and a source (22) of a volatile delivery-enhancing compound. The aerosol generating system (80) also includes at least one elastic member (48, 58) provided in the aerosol generating device (70) or the aerosol generating article (60) and relative to the heated The device element (72) is resiliently biased. At least one of the medicament source (18) and the volatile delivery-enhancing compound source (22) contacts the at least one resilient member (48, 58), and the aerosol generating system (80) is configured to heat The medicament source (18) and the volatile delivery-enhancing compound source (22) of the aerosol-generating article (60) such that the medicament source (18) has a higher concentration than the volatile delivery-enhancing compound source (22). ) high temperature.

Description

technical field [0001] The present invention relates to an aerosol generating system for generating an aerosol comprising a medicament. The present invention is particularly useful as an aerosol generating system for generating an aerosol comprising nicotine salt particles. Background technique [0002] Some devices for delivering nicotine or other medicament to a user include a source of a volatile acid, such as pyruvate, or other volatile delivery-enhancing compound and a source of nicotine or other medicament. The volatile delivery enhancing compound reacts with nicotine in the gas phase to form an aerosol of nicotine salt particles which is inhaled by the user. [0003] At room temperature, both pyruvate and nicotine are sufficiently volatile to form corresponding vapors that react with each other in the gas phase to form nicotine pyruvate particles. However, at room temperature, the vapor pressure of pyruvate is substantially greater than that of nicotine, resulting i...
