Description

A non-combustible heating stick comprising a foam-shaped aerosol-generating material disposed within a container The present invention relates to a cigarette containing a foam-shaped or mousse-shaped aerosol-generating material for use in the tobacco industry, particularly in non-combustible heated articles. The aerosol-generating material is provided in a container contained within a portion of an aerosol-generating article heated for smoking. Aerosol-generating articles, including aerosol-generating materials used in non-combustion heated (HnB) smoking devices, have been known since 1980. Nevertheless, these articles only began to become more popular after the 21st century, as research confirmed that HnB vapors release significantly fewer of most chemicals found in cigarette smoke. Furthermore, when HnB smoking articles are used within an HnB holder, no combustion emission process occurs. Therefore, there is general agreement that such smoking articles can be better known as aerosol-generating articles in that the generated aerosol is not smoke. Commercially available HnB systems, such as Glo (produced by British American Tobacco (BAT)) or IQOS (Philip Morris International (PMI)), include a charger, a holder, and a tobacco stick, plug, or capsule. When inserted into the holder, the tobacco stick is heated by an electronically controlled heating element. Patent document US 20150150302 relates to a rod for use as an aerosol-generating article comprising at least two sheets of tobacco material joined together and wrapped by a wrapper, wherein the sheets of tobacco material may be physically or chemically different from each other. The sheets of tobacco material may have the same thickness or different thicknesses, or may be crimped. An aerosol-generating substrate is provided in a portion that is in direct contact with a heat source. Patent document WO 2017/202965 relates to a method for providing an aerosol-generating device for use with an article such as a shape-deformable aerosol-forming substrate. Such an article has a layer of an aerosol-forming substrate and a second layer, which is an open layer, for example, a mesh arrangement. The open layer allows air and aerosol or material evaporated from the substrate to enter into the aerosol-generating article as well as into the open layer. The article may also have an outer paper layer, for example, cigarette paper, on top of the open layer and below the aerosol-forming substrate layer. US 2011/088708 A1 describes a smoking-capable filler material and a process for manufacturing the same, wherein the smoking-capable filler material comprises a blowing agent, a formulation capable of forming chemical crosslinks, and a crosslinking agent. It is disclosed that the smoking-capable filler material is a self-supporting foam when dried. Advantageously, drying the stabilized foam material further stabilizes the foam structure and enables further processing thereof. Additionally, it is disclosed that the foam material is dried to maintain stability. Despite the increasing popularity of existing HnB aerosol-generating materials and products, consumers are aware that they do not provide a taste and sensory experience comparable to conventional smoking products such as cigarettes or cigars. In particular, consumers seek currently available products that lack the actual taste of tobacco. In addition, existing non-combustible heated products and devices require heating the reconstituted tobacco material to very high temperatures exceeding 300°C and below 350°C, which requires insulating the heating device not only to avoid causing harm to the consumer but also to cool the generated aerosol before inhalation by the consumer, which is generally achieved by a polylactic acid (PLA) corrugated film introduced into the filter of the heated aerosol-generating article. Therefore, it would be advantageous to provide consumers with aerosol-generating articles and materials that offer a taste experience closer to actual tobacco and more enjoyable, and that require less heating for aerosol generation and consequently less cooling for consumption.

FIG. 2 illustrates a cross-sectional view of the portion containing the container, and the aerosol-generating material is contained within the container. FIG. 1 illustrates an exemplary embodiment of an aerosol-generating article (100) according to the present invention. The aerosol-generating article (100) has a cylindrical shape similar to a non-combustible heated article currently on the market. The aerosol-generating article (100) comprises a plurality of portions (10, 20, 30) arranged longitudinally in an end-to-end manner. One longitudinal end of the aerosol-generating article (100) represents a distal end (15), while the other longitudinal end of the aerosol-generating article (100) represents a proximal, mouse
