Definitions

  • the present invention relates to an aerosol-generating article and the method for manufacturing an aerosol-generating article.
  • the aerosol-generating article comprises an aerosol-generating substrate and a mouthpiece which is arranged downstream of the aerosol generating substrate.
  • Such an aerosol-generating article is generally used in heat-not-burn aerosol-generating devices.
  • the aerosol-generating substrate is at least partially contained in a wrapper for wrapping the aerosol-generating substrate. Said wrapper comprises a flavoring agent adhered to the surface facing towards the aerosol-generating substrate, thus directed inwards. This wrapper is usually made of paper.
  • the taste should not be distorted. Therefore, the aerosol-generating substrate should be kept in its original state and also while heated it should not take on other unwanted flavors of the wrapper.
  • the wrapper can be used to positively influence and intensify the taste. By doing so, also the external appearance must be considered. E.g. the outside of the wrapper must not show any discoloration.
  • Aerosol-generating articles are consumer goods produced in large quantities. Therefore, the method of production must be as simple as possible and process-secure to keep raw material consumption as well as costs low. Furthermore, it is desired to keep process reliability in production high.
  • WO 2014/012 841 A2 discloses an aerosol-generating article comprising a first wrapper enveloping at least partly a mouthpiece and an outer wrapper overlying the first wrapper.
  • a plurality of fragile capsules containing a flavor agent are provided in a flavored region of the surface of the first wrapper.
  • the outer wrapper comprises a cut-out portion exposing the capsules.
  • the capsules can be manually ruptured by the consumer prior or during use of the heat-not-burn aerosol-generating device.
  • This aerosol-generating device is very complex and cost intensive due to the double layer wrapper with cut outs in the upper layer Furthermore, handling is difficult since the consumer needs to release a flavor by an additional manual step. Also, the flavors are stored in micro capsulates, which are complexes to produce.
  • an aerosol generating article which consists of a plurality of elements assembled into a rod, comprising an aerosol-forming substrate and a volatile flavor-generating component disposed between the aerosol-forming substrate and the mouthpiece filter within the rod.
  • the volatile flavor-generating component is supported by a low resistance support element located between the aerosolforming substrate and the mouthpiece filter. Therefore, comparable to the application mentioned above, a very complex assembly with a plurality of different parts is required.
  • Document US 10 383 360 B2 discloses a smoking composition comprising a tobacco material and a flavor delivery system.
  • the flavor delivery system comprises a flavor material and a first wax material, forming a core.
  • a second wax material forming an encapsulated flavor particle surrounds the core and is disposed directly to the core.
  • the wax of first and second wax are different materials.
  • This document discloses a possibility to positively influence the taste of a base aerosol generating material by another flavor material.
  • the application discloses waxes in a radial layered arrangement, which also requires high process efforts.
  • WO 2015/028812 A1 discloses a method of producing a smoking article.
  • the smoking article comprises a smoke constituent reducing technology which is capable of reducing the concentration of a smoke constituent generated by a smoking article in use, thus it does not disclose fine particles of a flavoring agent which is attached to the inside of the inner surface of the wrapper.
  • the aim of changing the flavour of an aerosol-generating article or improving its taste is therefore not achieved with this invention.
  • US 4 941 486 discloses a cigarette comprising smokable material contained in the wrapping material.
  • the wrapping material has an intimate contact with a flavor precursor in an amount sufficient to provide alteration to the aroma of the sidestream smoke of the cigarette during burning.
  • the flavor precursor provides essentially no perceivable aroma characteristics to the cigarette prior use.
  • WO 2011/140430 A1 discloses a filter element for a smoking article.
  • the filter element includes a first segment of fibrous tow filter material.
  • a second segment of fibrous tow filter material is spaced in relation to the first segment and a cavity is positioned between the two segments of fibrous tow filter material.
  • the cavity contains a plurality of breakable capsules comprising a flavorant, wherein one segment of fibrous tow filter material includes an adsorbent material.
  • This invention also shows the disadvantage of a complex structure and the associated costs. In addition, due to the perforations, it is not possible to have an intact and unaltered wrapper.
  • the known aerosol-generating articles are based on different methods and designs to positively influence the taste of the main flavor carrier. However, all have in common, that they are production intensive due to a more-layer or more-material-design. Thus, these articles are more cost intensive than a single flavor source aerosol-generating article. Also, the externally unchanged appearance or intactness (e.g. no cut outs) of the wrapper is not ensured in state-of-the-art applications.
  • the wrapper should be intact and unaltered to reserve it for visually recognizable markings located on the outer surface of the wrapper.
  • the method of production should be simple and process-safe and as few as possible new parts and steps should be added therefore.
  • An aerosol-generating article comprises an aerosol-generating substrate and a mouthpiece downstream of the aerosol-generating substrate.
  • the aerosol-generating substrate is at least partially contained in a wrapper.
  • the wrapper comprises an inner surface and an outer surface, wherein the inner surface is facing towards the aerosol-generating substrate.
  • fine particles of a flavoring agent are adhered.
  • the flavor agent can be used to bring a further flavor to the main flavor of the aerosol-generating substrate, or to enhance the taste of the main flavor further. Therefore, the particles which are included in the flavoring agent may be fine tobacco particles or other flavorings. These flavors can be chemically produced or finely ground and treated raw materials.
  • the size of the flavor particles can determine how strong and how fast the consumer experiences the flavoring agent while smoking.
  • the size (sDso Sedigraph) of the particles is smaller than 100 pm, more preferable smaller than 60 pm, even more preferable smaller than 50 pm.
  • the size of the particles is smaller than 30 pm. This fine particle size enables a homogeneous adhering of the particles on the thin paper of the wrapper. This homogenous distribution is therefore part of the invention to improve the experience for the customer. Due to the preferred small particle size, the mass of the particles applied on the wrapper is small.
  • the mass of the homogeneously distributed particles is 1 - 2 % weight of the total weight of the wrapper.
  • the outer surface of the wrapper does not show any discoloration caused by the flavor generating substrate or flavoring agent, as the customer should get a visual pleasing outer appearance of the aerosol-generating article.
  • This outer appearance can also be used to give the customer information, e.g. brand, selected flavor, or date of manufacturing.
  • codes can be applied on the outer surface. Wherein the visually recognizable markings are preferably letters, symbols trademarks numbers and combinations thereof.
  • the wrapper has a grammage of 5 - 100 g/m 2 .
  • the grammage is further limited to a range of 8 - 80 g/m 2 ’ more preferably to 10 - 50 g/m 2 or even 12 - 40 g/m 2 .
  • the most preferred grammage of the wrapper is 12,5 - 25 g/m 2 .
  • a wrapper in this range shows the most advantageous characteristics in combination with an adhered flavoring agent on the inner surface of the wrapper.
  • Length and width of the wrapper preferably correspond to the size of the aerosol-generating article. This again is dependent on the heat-not-burn aerosol generating device. Therefore, different length and width are in use. The ratio of length and width is depending on the shape of the aerosol-generating article.
  • the length of the wrapper is in a range of 30 - 100 mm, preferably 40 - 90 mm. Even more preferred is a length of 50 - 80 mm. Most preferred is an embodiment with a length of the wrapper of 60 - 70 mm.

  • width of the wrapper which should be in a range of 10 - 50 mm, preferably 10 - 40 mm more preferably in a range of 10 - 30 mm and in a most preferred embodiment 10 - 25 mm. Even more preferred is a width of 10 - 20 mm. Most preferred is an embodiment with a width of the wrapper of 12 - 20 mm.
  • the width is perpendicular to the length of the wrapper and corresponds to the circumference of the aerosol-generating article.
  • the width is preferably slightly larger than the circumference of the aerosol-generating article to create a narrow overlap area.
  • the invention is further directed to a method for manufacturing an aerosol generating article.
  • the method for manufacturing the aerosol generating article according to the embodiments described comprises different clearly structured steps.
  • the aerosol generating substrate needs to be provided as it is produced in a several manufacturing process state of the art.
  • the wrapper needs to be provided in the already preferred dimensions. Since these process steps are state of art, they will not be explained further.
  • the flavoring agent is adhered to the first surface of the wrapper.
  • this can be conducted by a spray provided by a nozzle or other spray tools, which produce a fine spray through pressure so that the paper is homogeneously covered.
  • ultrasonic nozzles can be used to spray the flavoring agent on the first surface of the wrapper.
  • Whichever type of nozzle is used, it can be favorable to constantly control the application of the flavoring agent on the wrapper. For steering the process, different measures can be taken into account.
  • Spray-pressure and the distance of nozzle and wrapper can be used to determine spray quality and homogeneity of the application.
  • a nozzle with an adjustable spray-head can be used to influence the spray pattern in a favorable way. It is also possible to move the wrapper and/or the nozzle with respect to each other, e.g. towards or away from each other. At this it is depending on the installation and machinery, if it is favorable to move the nozzle, the wrapper or both relative to each other.
  • the application of the flavoring agent on the wrapper has an input to control this process step.
  • This input is preferably provided by an optical evaluation, e.g. by camera or photosensitive sensor or by any other non-contact measurement method, like e.g. laser.
  • the flavoring agent is applied in a liquid solution, therefore also a non-contact moisture measurement by using microwave radiation or a capacitive measuring method is feasible.
  • the surface roughness of the inner side of the wrapper after applying the flavoring agent can be used to stere the application of the flavoring agent.
  • the particles of the flavoring agent can be suspended in a liquid solution, this ensures an easy way to get a very homogeneous distribution of particles on the wrapper.
  • This liquid solution can be a transfer liquid solution, that means, it is removed from the wrapper after it is sprayed on the wrapper. In this variant of the method, it is only a temporary carrier of the flavoring agent particles.
  • a heat treatment can be conducted. In support for evaporation also a joint treatment by temperature and pressure is feasible. Also a longer resting period at room temperatures could be applied to evaporate the liquid of the suspended liquid solution. Heat irradiation by a heating lamp is another preferred embodiment.

  • the particles of the flavoring agent comprise tobacco.
  • the particle size determines processing quality during the spray application and also flavor releasing while smoking or vaping. Therefore, a preferred particle size (sDso Sedigraph) is smaller than 100 pm or more preferred smaller than 50 pm. In the most preferred embodiment, the particle size is smaller than 30 pm, as this is best for processing and flavor development while smoking.
  • the wrapper of the aerosol-generating article is marked on the second side, facing outwards.
  • This marking can include letters, symbols, trademarks, numbers and combinations thereof. These marks can be used to provide information like flavor or brand to the customer or to provide information of the manufacturing like badge and date of production. Also printed optical codes like QR codes or barcodes are possible marks on the second side of the wrapper, facing in an outward direction.
  • Printing prior or after applying the flavoring agent gives the degree of freedom to locate the printing machinery beside the spray nozzles of the spray application of the flavors. Therefore, both process steps can be executed from above. This prevents liquid from running while not dried.
  • the printing is a predominantly dry step, then a simultaneous application is feasible. Then printing machinery and nozzles for applying the flavoring agent are arranged on the opposite to each other with the wrapper in between.
