Definitions

  • the present invention relates to an aerosol-generating article with a filter that comprises a flavored segment containing at least one capsule and at least one dehydrated flavoring agent that is distributed at least partially inside said flavored segment.
  • the present invention also relates to a method to produce such filter segment.
  • Activated carbon particles are typically used and are usually embedded in a cellulose acetate filter segment or provided as charcoal beads in a cavity between two cellulose acetate filter segments while the smoke passes through the filter towards the mouth end of the filter.
  • smoke altering components can also be incorporated into the filter.
  • Those smoke altering components can in particular contain flavorants provided in the form of beads, which are arranged between filter plugs, within threads extending along the filter length or within breakable capsules encapsulating a liquid flavorant or neutral liquid such as water as wetting agent.
  • beads and threads provide inherent smoke altering upon consumption by a user
  • breakable capsules provide users with an opportunity to actuate smoke alteration "on demand", by crushing of the capsule manually or by biting the filter before or during use of the smoking article.
  • Such on-demand flavoring by crushable capsules has been well received among consumers in general.
  • the manufacturing of the crushable capsules and development of liquid flavors comprised therein is costly.
  • the processing of the capsules during filters and cigarettes manufacturing is constraining and can affect capsules integrity, leading to capsules defects and crushing during production, which affects the manufacturing efficiency and costs.
  • heat-not-burn smoking articles which have a similar structure to standard cigarettes, with a tobacco containing part attached to a filter part as a mouthpiece, but are made to be heated with a heating member or in a heating chamber of an electronic heating device rather than combusted have been marketed worldwide.
  • These new kind of smoking articles provide an alternative offer to traditional combustible cigarettes for consumers. They exhibit a similar structure to the conventional cigarettes, with a tobacco containing rod attached to a mouthpiece filter segment with a conventional tipping paper. However, they currently do not offer on-demand flavoring.
  • the filter comprises at least one flavored filter segment, through which an aerosol stream is passable from a distal to a proximal segment end of said flavored segment.
  • the flavored segment comprises at least one capsule arranged in said filter material, and at least one dehydrated flavoring agent distributed at least partially inside said filter material.
  • said capsule contains a liquid.
  • the placement of at least one liquid containing capsule, together with the dehydrated flavoring agent allows for on-demand flavoring of an aerosol stream generated from an aerosol-generating source of an aerosol-generating article such as a cigarette, a heat-not-burn stick or even an e-cigarette through hydration of the dehydrated flavoring agent upon crushing of the capsule to release at least part of the liquid therein.
  • an aerosol passing through the filter of the invention may be gently and long lastingly flavored as the dehydrated flavoring agent becomes hydrated in the filter material after crushing the capsule.
  • This provides a satisfying, progressive flavoring, which is become more intense at time lapses from the moment of crushing of the capsule, as opposed to simple capsule flavoring as known in the art, where the flavor intensity if higher right after crushing.
  • the flavored filter segment comprises more than one flavoring agents, e.g. two or more, to allow the consumer to have extra flavor experience and possibly to have flavors with different hydrophilic properties so as to ensure long lasting flavoring.
  • the dehydrated flavoring agent is embedded within and/or between the filter material of said segment. That way, the dehydrated flavoring agent can be distributed throughout the whole filter material of said segment.
  • the filter material of the flavored segment is impregnated with the dehydrated flavoring agent.
  • Dehydrated flavoring agents have longer shelf lives than hydrated agents and thus keep their flavor for a long time. Further, the manufacturing process is potentially easier and cheaper to impregnate the flavor agent and to place the capsule into the same filter than needing to use separate pieces and segmentation.
  • the flavoring agent is a powder or contains a powder.
  • a powder form of the flavoring agent can be best distributed within the filter material.
  • the size of the dehydrated powder particles is less than 1 mm, preferably less than 0.8 mm, preferably less 0.5 mm and larger than 0.05 mm, preferably larger than 0.1 mm, preferably larger than 0.2 mm.
  • larger particles will have a high chance of falling out of the end of the filter at the open end into the consumers mouth. Particles smaller than 0.05 mm are difficult to produce and to handle during production of the flavored filter segment.
  • the dehydrated flavoring agent is formed from plant material capable of releasing flavor into an aerosol generated from an aerosol-generating substrate, for example through heating or combusting thereof.
  • these flavoring agent particles are discrete, solid particles, which are particularly soluble in water and may be formed of e.g. herbaceous plant material, which has been subjected to a mechanical process to densify the plant material or crystals, such as menthol crystal. It is also possible that the dehydrated flavoring agent is composed of originally tasteless particles that have been processed and flavored.
  • Such material will release an especially high amount of flavor and may contain, mints, such as peppermint and spearmint, lemon balm, basil, cinnamon, lemon basil, chive, coriander, lavender, sage, tea, thyme or a combination thereof.
  • mints such as peppermint and spearmint
  • lemon balm basil
  • cinnamon lemon basil
  • chive coriander
  • lavender sage
  • tea thyme
  • the flavor granules comprise non-tobacco plant material.
  • said capsule is situated within said flavored segment and spaced from the proximal segment end along a longitudinal direction of the filter.
  • said capsule is also concentrically arranged around a longitudinal axis of the flavored filter segment and particularly within an offset of a maximum of 60%, preferably of 40%, more preferably of 20% of the radius of the filter.
  • the capsule is spaced to a distal end of the flavored filter segment.
  • the spacing between the capsule and the proximal end of the filter segment is larger than the spacing between the capsule and the distal end of the filter. It is also possible that the spacing between the capsule and the proximal end of the filter segment is smaller than the spacing between the capsule and the distal end of the filter. It is further possible that the spacing between the capsule and the proximal end of the filter segment is similar to the spacing between the capsule and the distal end of the filter segment, so that the capsule is placed in the middle of the filter segment. This arrangement guarantees that the capsule is situated close to the middle of the filter segment or close a distal or proximal end of the filter segment. Thus, there are less interfaces for a released filling of the capsule to escape or leak from the flavored filter segment. During use of the inventive filter the filling of the capsule can then be brought into contact or mixed with an aerosol produced from an aerosol-generating source to which the filter is attached or adjoined.
  • said capsule comprises a liquid substance and allows the release of said liquid substance by activation.
  • the capsule can be activated by breaking the capsule due to an external force so that the consumer can decide whether he wants to activate the release of capsules filling or not.
  • two or more capsules with different fillings and/or flavors are incorporated into the flavored filter segment so that for example, the user can selectively break one or more of them to selectively customize the taste by crushing specific capsules hosting e.g. the wanted flavor and/or mix of flavors.
  • the filter material of the flavored filter segment will be impregnated with the liquid substance and thus, the filter may be impregnated with additional flavors.
  • said liquid substance contains an aqueous solution, typically water and/or comprises a flavor solved in a liquid.
  • the liquid is water.
  • Water can make more direct contact with the flavor agent without having to flow into a separate neighboring segment. Further, water will hydrate the dehydrated flavoring agent, so that the hydrated flavoring agent is capable of releasing much more flavor to the smoke than in their dehydrated form. If the liquid substance contains a flavor solved in the liquid, such flavor can be mixed with the flavor of the dehydrated flavoring agent allowing the consumer to have a special taste experience.
  • said capsule allows the release of said substance in a specific direction with respect to the longitudinal direction of the filter.
  • Directional capsules may in particular be in the form described in EP 3531846 A1 , to name of the present applicant.
  • the substance contained in the capsule is released towards the distal end of the flavored filter segment, to avoid its content flowing towards the proximal end where a user outs his mouth in use.
  • the filter and/or the capsule has a circular or oval cross section.
  • Oval or circular cross sections result in a good and comfortable feeling when holding a cigarette with a filter between fingers or lips while puffing said cigarette.
  • Capsules can be broken very easily, when they are shaped circular or oval, while being less prone to breaking through inadvertent pressing of the filters during manufacturing.
  • capsules may destroy the fibers of the filter material.
  • a polygonal shape, especially with rounded corners would also be possible.
  • the filter further comprises a carbon filter segment containing activated carbon.
  • activated carbon particles are situated within another filter segment of the filter.
  • Such a carbon containing filter segment is particularly impregnated with activated carbon particles, which may also be flavored.
  • activated carbon particles are preferably used to filtrate certain constituents in the smoke and therefore the overall filtration of the smoke is improved with the removal of unwanted chemical components from the smoke.
  • the carbon containing filter segment is completely arranged longitudinally at the distal end of the flavored filter segment, which may in use be at the connection end of the inventive filter with a source of aerosol-generating material such as a tobacco containing rod of a smoking article or heat-not-burn article.
  • an aerosol-generating article which comprises an aerosol-generating material segment comprising an aerosol-generating segment having a proximal end and a distal end and a filter according to the previous description attached at the proximal end of the aerosol-generating material segment.
  • the aerosol-generating material segment preferably comprises tobacco.
  • the present invention further provides a method to produce a flavored filter segment for a filter according to the above description, comprising the steps of:
  • step b at least one dehydrated flavoring agent is provided, which may for instance be produced by spray drying.
  • the dehydrated agent may be formed from a slurry comprising e.g. water, a carrier substance and/or at least one flavored substance, which is brought into a stream of hot gas and will be atomized.
  • the slurry will preferably be dried to a fine dry powder containing the flavor of the flavored substance.
  • the drying procedure takes place within 5 seconds, preferably within 3 seconds, preferably within 1 second.
  • the slurry is sprayed preferably using a nozzle into a controlled drop size and dried very rapidly, trapping the volatile flavor constituents inside the droplets.
  • the resulting powder is then recovered via cyclone collectors.
  • the flavor retention is quite satisfactory and the dryer operating parameters are properly chosable.
  • the flavor retention is maximized by using a high infeed level, high viscosity infeed, an optimum inlet, high exit gas temperatures and/or high molecular weight flavor molecules.
  • An optimum inlet of less than 300°C, preferably less than 250°C, preferably less than 220°C and/or higher than 80°C, preferably higher than 100°C, preferably higher than 140°C is preferred.
  • exit gas temperatures of less than 300°C, preferably less than 200°C, preferably less than 160°C and higher than 60°C, preferably higher than 80°C, preferably higher than 100°C are preferred.
  • the shelf life of oxidizable flavor compounds is strongly influenced by the flavor carrier, but is increased due to the dehydration process.
  • the advantage of using a dehydration process is the preservation of flavor of flavored powder as well as the increased choice of possible flavor and the possibility of a combination of flavor compounds.
  • impregnation of the filter material with at least one dehydrated flavoring agent takes place just before or after the addition of a plasticizer to the filter material during the production process of a shaped filter material.
  • the filter material is impregnated with said dehydrated flavoring agent after the addition of a plasticizer and before shaping the filter material.
  • the plasticizer is triacetin or another softening agent with a high boiling point.
  • the advantage of impregnating the filter material before its shaping is that the dehydrated flavoring agent can be distributed throughout the whole filter and between the fibers of the filter material. Preferably the dehydrated flavoring agent is dusted on the unshaped filter material.
  • step d the filter material that is impregnated with the dehydrated flavoring agent is shaped into a desired form.
  • a desired form has a rod shape.
  • a rod shaped filter can easily be cut into several pieces in step e. and is very suitably for use in any kind of smoking articles.
  • the flavoring agent comprises a powder or is a powder.
  • a powder form of the flavoring agent can be best dusted on and distributed within the filter material.
  • the size of the dehydrated powder particles is less than 1 mm, preferably less than 0.8 mm, preferably less than 0.5 mm and/or larger than 0.05 mm, preferably larger than 0.1 mm, preferably larger than 0.2 mm. Any larger particles will begin to affect the layering of the cellulose acetate in the filter. Further, larger particles will have a high chance of falling out of the end of the filter at the open end into the consumers mouth. Particles smaller than 0.05 mm are difficult to produce and to handle during production of the flavored filter segment.
  • lognormal distributed particle sizes of the flavoring agent the size of particles to be impregnated in the filter material can be best determined and the risk that particles too large or too small for the desired purpose will find their way into the filter is extremely low.
  • a plurality of capsules are incorporated periodically into the filter rod and each cut flavored segment comprises at least one capsule arranged therein.
  • the placement of at least one capsule, per flavored segment allows the addition of liquid and/or flavored material and/or aroma in a liquid and/or powdered and/or another form.
  • the shaped filter material comprising the dehydrated flavoring agent and the capsule is cut into filter segments with specific dimensions.
  • such filter segments have a rod shape and are particularly cut into in such a way that the space between the capsule and a first end of the filter segment is larger than the spacing between the capsule and a second end of the filter segment. It is also possible that the filter is cut in such a way that the space between the capsule and the first end and the second of the filter segment is similar, so that the capsule is placed in the middle of the filter segment. This arrangement guarantees that the capsule is situated close to the middle of the filter segment or close a distal or proximal end of the filter segment.
