Description

Aerosol-generating article comprising a plurality of portions of an aerosol-generating substrate

The present invention relates to an aerosol-generating article comprising a plurality of portions of an aerosol-generating substrate for generating an inhalable aerosol when heated. The invention also relates to an aerosol-generating system comprising an aerosol-generating article and an aerosol-generating device configured to heat the aerosol-generating article.

Aerosol-generating articles in which an aerosol-generating substrate, such as a tobacco-containing material, is heated without combustion are known in the art. The goal of these 'heated' aerosol-generating articles is to reduce known hazardous smoke components of the type produced by combustion and thermal decomposition of tobacco in conventional cigarettes.

Typically in heated aerosol-generating articles, aerosols are generated by heat transfer from the heat source to an aerosol-generating substrate that is physically separate. In use, the volatile compounds are released from the aerosol-generating substrate by heat transfer from the heat source to the aerosol-generating substrate and are entrained in the air drawn through the aerosol-generating article. The released compounds condense as they cool, forming an aerosol that is inhaled by the user.

A number of portable aerosol-generating devices are known in the art that are configured to heat the aerosol-generating substrate of a heated aerosol-generating article. These include electrically heated aerosol-generating devices in which aerosols are generated by heat transfer from one or more electrical heating elements of the aerosol-generating device to the aerosol-generating substrate of the heated aerosol-generating article. Known portable, powered aerosol-generating devices typically include a battery, control electronics, and one or more electric heating elements for heating the aerosol-generating substrate of a heated aerosol-generating article specifically designed for use with the aerosol-generating device.

Some known electrically operated aerosol-generating devices include an internal heating element configured to be inserted into the aerosol-generating substrate of a heated aerosol-generating article. Other known electrically operated aerosol-generating devices include one or more external heating elements. For example, WO 2020/115151 A1 discloses an aerosol-generating system comprising an aerosol-generating article and an electrically operated aerosol-generating device comprising an external heating element surrounding the outer periphery of the aerosol-generating article.

Electrically operated aerosol-generating devices comprising an inductor configured to inductively heat an aerosol-generating substrate of a heated aerosol-generating article are also known in the art. For example, WO 2015/176898 A1 covers aerosol-generating articles comprising an elongated susceptor in thermal contact with an aerosol-generating substrate, and an electrically operated aerosol-generating device having an inductor for heating the aerosol-generating substrate. The generation system is being launched. In use, the fluctuating or alternating electromagnetic field generated by the inductor induces eddy currents within the susceptor, causing the susceptor to heat as a result of resistance losses (Joule heating) and/or hysteresis losses if the susceptor is magnetic. . The heat generated within the susceptor is transferred to the aerosol-forming substrate by conduction.

One known type of heated aerosol-generating article, commonly referred to as heated-non-combustible tobacco product or heated tobacco product, comprises a solid aerosol-generating substrate comprising tobacco material that is heated to produce an inhalable aerosol. Known heated tobacco products typically comprise a single piece of an aerosol-generating substrate. In use, air is typically drawn through the entire length of a single portion of the aerosol-generating substrate during each puff by the user. This can adversely affect the quality and consistency of the aerosol delivered to the user in successive puffs. Especially if the user stops using heated tobacco products and then subsequently resumes it. For example, if a user discontinues and subsequently resumes use of a heated tobacco product, the quality of the aerosol delivered to the user after resuming use of the heated tobacco product will be different from that delivered to the user prior to cessation of use of the heated tobacco product. The quality can be significantly worse than that of the aerosol. As a result, if the user stops using the heated tobacco product, the user may choose to discard the partially used heated tobacco product rather than resume use of the heated tobacco product.

It would be desirable to provide an aerosol-generating article in which the quality and consistency of the aerosol delivered to the user in successive puffs is improved compared to known heated tobacco products of the type described above.

It would be desirable to provide an aerosol-generating article that allows use of the aerosol-generating article to be discontinued and subsequently resumed by the user without adversely affecting the quality of the aerosol delivered to the user.
