Problems solved by technology

This may cause the temperature of the aerosol-forming substrate to drop outside the desired range, thereby affecting the performance of the aerosol-generating article
If the temperature of the aerosol-forming substrate drops too low, it may, for example, adversely affect the consistency and amount of aerosol delivered to the user

example 1

[0195]In order to form the inorganic glue layer, inorganic sodium silicate glue having a silica content of 28.5% to 30.0%, a sodium oxide content of 8.5% to 9.0%, and a molar ratio of 3.3 to 3.5 is used about Figure 3A and 3B The method described above is applied between the combustible heat source and the packaging material.

example 2

[0197] In order to form the inorganic glue layer, an inorganic sodium silicate glue with a silica content of about 29.9%, a sodium oxide content of about 9.4%, and a molar ratio of about 3.3 was used with respect to Figure 3A and 3B The method described above is applied between the combustible heat source and the packaging material.

example 3

[0199] Inorganic sodium silicate glue having a silica content of 33.1% to 34.1%, a sodium oxide content of 12.0% to 13.0%, a molar ratio of 2.6 to 2.9, and a dry solid content of 45.1% to 47.1% for forming an inorganic glue layer use about Figure 3A and 3B The method described above is applied between the combustible heat source and the packaging material.

Abstract

A multi-segment assembly (50) is provided for an aerosol-generating article (2), the multi-segment assembly comprising a combustible heat source (4); an aerosol-forming substrate (10) downstream of the combustible heat source; and a length along the combustible heat source At least a portion of a wrapping material (38) surrounding the combustible heat source. The combustible heat source has a shaped recess (110) on its outer surface (102), which is at least partially filled with an inorganic glue (42).

Description

technical field [0001] The present invention relates to multi-section assemblies for aerosol-generating articles. In particular, the present invention relates to a multi-section assembly having a combustible heat source for heating an aerosol-forming substrate downstream of the combustible heat source, and wrapping material surrounding at least the rear portion of the combustible heat source. The invention also relates to combustible heat sources for such multi-segment assemblies and aerosol generation comprising such multi-segment assemblies. Background technique [0002] Various smoking articles in which tobacco is heated rather than combusted have been proposed in the art. One object of such 'heated' smoking articles is to reduce known types of noxious smoke constituents produced in conventional cigarettes by the combustion and pyrolytic degradation of tobacco. In one known type of heated smoking article, an aerosol is generated by transferring heat from a combustible h...
