Definitions

  • the present invention relates to the field of tobacco, especially tobacco-containing foam-like or mousse-like aerosol-generating material for use in a heating type vaping device or an oven-type vaping device.
  • Aerosol-generating articles comprising aerosol-generating material used in a heat-not-burn (HnB) vaping device have been known since 1980. It is nonetheless only becoming more popular since the turn of the 21 st century, as studies have shown that HnB vapour releases significantly less of most of the chemicals in tobacco smoke. Moreover, none of the combustion emission process occurs when the HnB smoking articles are used in the HnB holder Hence, it is generally agreed that the aerosol generated is not smoke, and thus such a smoking consumables could be better known as an aerosol-generating consumables or an aerosol-generating article.
  • HnB heat-not-burn
  • Patent document US20170280769 relates to a cartridge for an electronic vaping device.
  • a roll of material is impregnated with a coating of additive of tobacco products like a pH adjusting agent, a vapour former, flavourant, tobacco material, and nicotine.
  • the roll of material is positioned between a heater and a mouth-end insert.
  • the roll of material may be formed into a sheet having the additive spread on both the sides. Nevertheless, the cartridge as described therein has a poor vapour performance due to the materials chosen for the cartridge.
  • HnB aerosol generating articles Although there exist different shapes and sizes of HnB aerosol generating articles in the market, consumers at the same time acknowledge that they do not offer a comparable taste and sensory experience to conventional smoking articles such as cigarettes or cigars. In particular, consumers find currently available products to lack real tobacco taste.
  • a first aspect of the invention relates to a rolled sheet coated on at least one of its surface with a foam of tobacco-containing aerosol-generating substrate.
  • a second aspect of the invention relates to a method of manufacturing an aerosol-generating article according to the present invention, comprising the steps of: a. Providing a sheet; b. Coating at least one face of the sheet with a foam of aerosol generating substrate; c. Rolling up the sheet to form the aerosol-generating article.
  • the rolled sheet having a foam coated thereon according to the present invention is suitable for the generation of aerosol.
  • the large surface of the sheet provides large area for the foam to be applied on. Furthermore, the rolled sheet further increases the amount of the surface area of the sheet.
  • the foam is applied to both surface of the rolled sheet.
  • the foam which comprises aerosol-generating substrate may be sufficient to be applied on only one surface of the sheet to provide sufficient vapour or aerosol. Both surfaces of the sheet can be applied with the foam when stronger, richer, or longer vaping session is desired.
  • the rolled sheet is only partially coated or fully coated with the foam.
  • the foam may be provided to only about half of the surface on one side or each sides of the sheet in order to reduce the amount of unused foam. Nevertheless, the foam is preferably evenly coated to the surface of the rolled sheet compared to methods such as spraying to ensure a smooth release and constant release of aerosol.
  • a plurality of perforations are provided to the rolled sheet.
  • the perforations provided to the sheet encourages the air flow, thereby higher aerosol can be released when heated air and flows through the perforations and contact with more surface of the sheet.
  • a rolled sheet having no perforations means that the heated can only flow along the longitudinal axis of the rolled sheet. Having a plurality of perforations can thereby promote the interaction of the heated air and the surface of the coated sheet.
  • the rolled sheet has a wavy surface, embossed or debossed surface, a studded surface, a pointed surface or a corrugated surface. These rolled sheets are thereby provided with an increased surface, vapour performance of the aerosol-generating article of the present invention is thereby increased.
  • the rolled sheet has a corrugated sheet structure. This embodiment is particularly advantageous as a plurality of longitudinal axis of air channel can be created, thereby increases the vapour performance (aerosol performance) or the present invention.
  • the rolled sheet comprises a multiple layers of sheets stacked on top of each other, wherein at least one, two, three or four sheets are coated with the foam to form the rolled sheet.
  • the surface of the rolled sheet are preferably provided with wavy surface, embossed or debossed surface, a studded surface, a pointed surface, a corrugated surface, or a plurality of perforations to avoid the sheets from lying completely to each other as no air flow between these sheets is possible.
  • These uneven surfaces provided to the surface of the rolled sheet encourage air flow to flow between these stacked layers of sheets, thereby increases the vapour performance.
  • the sheets coated with the foam are separated by one or more sheets without coating.
  • the use of more layers of sheet may allow a longer vaping session, however the amount of the foam can be reduced by not coating on each layers of the rolled sheet.
  • the rolled sheet is an inert and/or porous and/or flexible material such as a plastic material, reconstituted tobacco. These materials are suitable as they are not being burnt but instead heated. Nevertheless, it is preferably that the plastic material is made of thermo resistance material.
  • the rolled sheet is fibrous material such as a woven or an unwoven material. These materials do not break off easily upon heated by high temperature, thereby reducing waste and ashes from the aerosol-generating article.
  • the method further comprises one or more of the following steps: a. Stacking up multiple sheets on top of each other, wherein the sheets comprises only sheets coated with a said foam of aerosol generating substrate or a mix of coated or uncoated sheets; b. Cutting the rolled sheet perpendicular to its longitudinal axis; c. Providing a fastening means to the rolled sheet to prevent unrolling of the sheet; d. Providing a wrap to the rolled sheet for packaging purpose.
  • cross section profile of the aerosol-generating consumable article or a component of the aerosol-generating article refers to the transverse cross-section unless stated otherwise.
  • a “tobacco-containing” can be any compound, mixture, particle matter, and/or solution that contains and/or carries a constituent of tobacco, either artificially included or naturally contained in tobacco, e.g. tobacco, tobacco particles, tobacco flavor and/or nicotine in any available form (e.g. nicotine salts).
  • tobacco, tobacco particles, tobacco flavor and/or nicotine in any available form (e.g. nicotine salts).

  • aerosol-generating reconstituted tobacco material have poor vaporizing performance, as a large portion of the consumable products have not been heated properly to release the vapour and/or aerosol, thereby resulting in the wasting of the consumables, as excess amount of the tobacco material have not been used.
  • the rolled sheet 100 of the present invention is not only easy to manufacture and has lower cost, its vapour performance is also increased due to the foam coated on the surface of the rolled sheet 100 can be heated evenly and more effectively while minimising the amount of tobacco-containing foam applied on the rolled sheet 100.
