• the aerosol-generating material may comprise a binder, such as a gelling agent, and an aerosol former.
• a substance to be delivered and/or filler may also be present.
• a solvent such as water, is also present and one or more other components of the aerosol-generating material may or may not be soluble in the solvent.
• the aerosol-generating material is substantially free from botanical material.
• the aerosol-generating material is substantially tobacco free.
• the aerosol-generating material may comprise or be in the form of an aerosol-generating film.
• the aerosol-generating film may comprise a binder, such as a gelling agent, and an aerosol former.
• a substance to be delivered and/or filler may also be present.
• the aerosol-generating film may be substantially free from botanical material.
• the aerosol-generating material is substantially tobacco free.
• the aerosol-generating film may have a thickness of about 0.015 mm to about 1 mm.
• the thickness may be in the range of about 0.05 mm, 0.1 mm or 0.15 mm to about 0.5 mm or 0.3 mm.
• the aerosol-generating film may be continuous.
• the film may comprise or be a continuous sheet of material.
• the sheet may be in the form of a wrapper, it may be gathered to form a gathered sheet or it may be shredded to form a shredded sheet.
• the shredded sheet may comprise one or more strands or strips of aerosol-generating material.
• the aerosol-generating film may be discontinuous.
• the aerosol-generating film may comprise one or more discrete portions or regions of aerosol-generating material, such as dots, stripes or lines, which may be supported on a support.
• the support may be planar or non-planar.
• the aerosol-generating film may be formed by combining a binder, such as a gelling agent, with a solvent, such as water, an aerosol-former and one or more other components, such as one or more substances to be delivered, to form a slurry and then heating the slurry to volatilise at least some of the solvent to form the aerosol-generating film.
• a binder such as a gelling agent
• a solvent such as water
• an aerosol-former such as one or more other components, such as one or more substances to be delivered
• the slurry may be heated to remove at least about 60 wt%, 70 wt%, 80 wt%, 85 wt% or 90 wt% of the solvent.
• the aerosol-generating material may comprise or be an "amorphous solid".
• the aerosol-generating materiel comprises an aerosol-generating film that is an amorphous solid.
• the amorphous solid may be a "monolithic solid".
• the amorphous solid may be substantially non-fibrous.
• the amorphous solid may be a dried gel.
• the amorphous solid is a solid material that may retain some fluid, such as liquid, within it.
• the amorphous solid may, for example, comprise from about 50wt%, 60wt% or 70wt% of amorphous solid, to about 90wt%, 95wt% or 100wt% of amorphous solid.
• the amorphous solid may be substantially free from botanical material.
• the amorphous solid may be substantially tobacco free.
• the aerosol-generating material may comprise or consist of plant/botanical material.
• the term “botanical material” includes any material derived from plants including, but not limited to, leaves, bark, fibres, stems, roots, seeds, flowers, fruits, pollen, husk, shells or the like.
• the term “botanical material” refers to solid plant matter (i.e., part of a plant) and does not encompass a "botanical extract”.
• Example botanicals are tobacco, eucalyptus, star anise, hemp, cocoa, cannabis, fennel, lemongrass, peppermint, spearmint, rooibos, chamomile, flax, ginger, ginkgo biloba, hazel, hibiscus, laurel, licorice (liquorice), matcha, mate, orange skin, papaya, rose, sage, tea such as green tea or black tea, thyme, clove, cinnamon, coffee, aniseed (anise), basil, bay leaves, cardamom, coriander, cumin, nutmeg, oregano, paprika, rosemary, saffron, lavender, lemon peel, mint, juniper, elderflower, vanilla, wintergreen, beefsteak plant, curcuma, turmeric, sandalwood, cilantro, bergamot, orange blossom, myrtle, cassis, valerian, pimento, mace, damien, marjoram, olive, lemon
• the mint may be chosen from the following mint varieties: Mentha arvensis, Mentha c.v., Mentha niliaca, Mentha piperita, Mentha piperita citrata c.v., Mentha piperita c.v., Mentha spicata crispa, Mentha cordifolia, Mentha longifolia, Mentha suaveolens variegata, Mentha pulegium, Mentha spicata c.v. and Mentha suaveolens.
• the botanical is selected from eucalyptus, star anise, cocoa and hemp.
• the botanical is selected from rooibos and fennel.
• the botanical material comprises leaf material.
• the botanical material is tobacco material.
• a "non-combustible" aerosol provision system is one where a constituent aerosol-generating material of the aerosol provision system (or component thereof) is not combusted or burned in order to facilitate delivery of at least one substance to a user.
• the delivery system is a non-combustible aerosol provision system, such as a powered non-combustible aerosol provision system.
• the non-combustible aerosol provision system is an electronic cigarette, also known as a vaping device or electronic nicotine delivery system (END), although it is noted that the presence of nicotine in the aerosol-generating material is not a requirement.
• END electronic nicotine delivery system
• the non-combustible aerosol provision system is an aerosol-generating material heating system, also known as a heat-not-burn system.
• a heat-not-burn system is a tobacco heating system.
• the disclosure relates to consumables comprising aerosol-generating material and configured to be used with non-combustible aerosol provision devices. These consumables are sometimes referred to as articles throughout the disclosure.
• the non-combustible aerosol provision system such as a non-combustible aerosol provision device, may comprise a power source and a controller.
• the power source may, for example, be an electric power source or an exothermic power source.
• the exothermic power source comprises a carbon substrate which may be energised so as to distribute power in the form of heat to an aerosol-generating material or to a heat transfer material in proximity to the exothermic power source.
• the non-combustible aerosol provision system may comprise an area for receiving the consumable, an aerosol generator, an aerosol generation area, a housing, a mouthpiece, a filter and/or an aerosol-modifying agent.
• the consumable for use with the non-combustible aerosol provision device may comprise aerosol-generating material, an aerosol-generating material storage area, an aerosol-generating material transfer component, an aerosol generator, an aerosol generation area, a housing, a wrapper, a filter, a mouthpiece, and/or an aerosol-modifying agent.
