Definitions

  • the present invention relates to the field of tobacco, in particular to reconstituted tobacco as well as aerosol-generating articles.
  • the present invention further relates to smoking devices, especially to an electrically heated e-liquid system or an electrically heated aerosol-generating system.
  • Heated tobacco inhaler devices are referred to as “heat-not-burn” systems (HNB). They provide a more authentic tobacco flavour compared to electronic cigarettes, which deliver an inhalable aerosol from heating of a liquid charge comprising aerosol formers, flavorants, and often nicotine.
  • the HNB system s working principle is to heat a tobacco material comprising an aerosol-forming substance (such as glycerine and/or propylene glycol) which vaporises during heating and creates a vapour that extracts nicotine and flavour components from the tobacco material.
  • the tobacco substance is heated to between 200 and 350°C, which is below the normal burning temperatures of a conventional cigarette.
  • the inhaler device is typically a hand-held heater, which is configured to receive rod-shaped consumable articles.
  • Illicit trade of aerosol-generating articles is a problem, as counterfeit articles in particular may be of inferior quality, may not guarantee a controlled delivery amount of aerosol or may not be suited to a specifically dedicated aerosol generating system.
  • a code or equivalent marking containing information about the article may be arranged onto an outer surface of the article, for it to be detected in use or prior use with a certain device. This allows to check for authenticity of the consumable article and in case of negative check, to provide an appropriate control, such as to power off or correctly adjust the heating system with which it is used.
  • WO201 9185747 discloses an e-cigarette comprising an article that includes an indicia, arranged on a surface of the article, and which is indicative of an encoded parameter associated with the article.
  • the e-cigarette also comprises a sensor arrangement to sense the indicium to identify or recognize the article.
  • US20190008206A1 discloses a smoking article comprising an indicium printed on the outer wrapper paper of the smoking article and represents a type of smoking article and may be in the form of pattern or one/two-dimensional barcode.
  • the indicium includes different grey levels that can be generated by printing in dots which have smaller size. Such indicium is easily detectable and reproducible and may contain only a small density of information, or to be provided with an unacceptably large size.
  • the system described in US20190008206 A1 relies on printed indicia which optical properties have to match the LEDs used in the sensor module, such as having specific infrared absorption bands.
  • the invention is related to a method of identifying a consumable in an aerosol generating device comprising: - providing a consumable comprising identification information in the consumable identifiable by identification means of the device,
  • variable characteristic is an identifiable shape of the cutting edge of said at least one layer.
  • the shape may for instance be toothed, notched, undulated, or designed with a non-nil angle relative to the extension direction of the layer.
  • the cutting edge may have a variation of curvature and/or inclination relative to the longitudinal axis of the consumable article.
  • the pattern may be varied in amplitude, period, width, and combinations thereof.
  • the shape of the cutting edge may be produced in a repetitive way during the manufacturing process.
  • the shape of the cutting edge may be varied depending on the type of article to be identified, e.g., to distinguish between different tobacco blends.
  • the optical properties of the cutting edge can be identified under light by an optical detector, such as photodiodes, of the aerosol generating device.
  • variable characteristic may also be, at least, a spectral characteristic of at least a portion of said at least one layer.
  • the characteristic is the optical property of an insert arranged in or on said at least one layer. Inserts may be present in an article, for example rigidifying layers as further described.
  • the characteristic is a reduction or increase of the thickness of the wrapper or rigidifying component.
  • the variation of the characteristic may enable to distinguish different types of article from others.
  • the at least one layer may comprise a conductive thread arranged in or on said at least one layer.
  • Figure 23 shows the shape of a glue layer for detection that is present in a manufactured aerosol-generating article.
  • the term “constituents” refers to the detailed composition of the aerosol generating substance, for example tobacco, aerosol formers, binders, flavouring agents, nicotine, and combinations thereof.
  • An aerosol-forming substrate may be provided in a stable support. Such a support may be in the form of a powder, granules, small strips, sheets, or foam.
  • Fig. 2 illustrates a typical cross-section aerosol-generating article 1 comprising a layer 10 that is typically a glue layer 10.
  • the article 1 comprises the further preferred elements 1 a-1 f: a consumable section T; - a consumable paper wrap 1a, for example a tobacco paper wrap 1a;
  • a layer 10 may be electrically conductive over a first length L1 and have less optical reflection over a second length L2.
  • the combination of the information on the electrical property of said first length L1 and the optical property of said second length L2 may be used as a more complex variable characteristic to identify if the consumable 1 is a genuine product.
  • said at least one layer 10 is an array of glue bands, as illustrated in the embodiments of Figures 3, 4, 5, 6, 8, 14 and 15.
  • said at least one layer 10 has non-uniform geometry in its length and/or its width.
  • Figures 1 , 10 and 11 illustrate examples of layers 10 that have portions 10a, 10b having a greater width and/or thickness than the remaining parts of the layer 10.
  • layers 10 may have at least a portion having a conical shape in a horizontal X-Z, Y-Z plane.
  • the layer 10 as described herein may have several optical functions such as:
  • a layer 10 may deviate and reflect an incident light beam 220;
  • the internal reflection of a light beam in a layer 10 may be enhanced by a reflection layer that may be arranged to a layer, such as a metallic coating layer, not illustrated in Figures.
  • a detector system may be arranged at different locations along a glue layer 10 , and in variants more than one detector system 300 may be arranged in front of outcoupling areas of a light-guiding layer 10. In the embodiments illustrated in Fig.21 light is transferred by maximal 4 internal reflections in the layer 10.
  • the incoupling and outcoupling (A-D) areas may be configured to constitute a recognizable and unique pattern.
  • a detector system 300 may detect 4 outcoupled light beams and provide a signal comprising 4 intensity steps as illustrated in Fig.21.
  • a glue layer 10 may be realized in production so that it comprises a regular pattern of simple ridges that may provide the function of incoupling and outcoupling (A-D) areas.
  • A-D incoupling and outcoupling
  • Such incouplers and outcouplers A,B,C,D arranged in a layer 10 of an article 1 may also be realized by imposing a slight prismatic shape that can be easily replicated in the manufacturing process of the article 1 .
  • incoupling surfaces may have also the function as outcoupling surface, which is the case in the example of Fig.21.
  • incouplers and outcouplers may be different areas or shapes or structures arranged on said layer 10.
  • light beams 220 as used in the invention may be ambient light or light provided by a light emitting system 200 as illustrated in Fig.13.
  • a light emitting system 200 comprises a light source 210 that may be a UV, visible or infrared light source. A light source having shorter wavelengths than the wavelengths of UV light may be used. Due to the very limited space available in aerosol-generating devices, light sources 210 are preferably semi conductor light sources such as LEDs, SLEDs or semiconductor light sources .
  • Light sources and light detectors may be arrays of light sources, not illustrated in the figures, and arrays of light detectors 310 as illustrated in the embodiment of Fig.18.
  • the detectors may be distributed circumferentially around the article such as at a certain angular path (e.g. 90 degrees).
  • the identification of the identification information that is encoded by at least one variable characteristic as described herein, may be detected by identification means of an aerosol-generating device 2.
  • the identification means are preferably, but not necessarily, optical detection means. Indeed, in embodiments said optical detection means may imply simple detectors or may require an imaging system 300 for providing and processing an image 400 of said characteristic of said at least one layer 10.
  • the articles 1 may also be detected during or after their introduction in a package.
  • the characteristics of said layer 10 may be well known from the manufacturing process and may not vary with time or they may vary according to well-determined production cycles.
  • a device may recognize at least two typical characteristics of a layer and identify that the article is genuine. For example if a layer 10 of a genuine product 1 has a central blob 10a (as illustrated in Fig.1 ) and this central blob 10 is displaced during a new production cycle, the device may recognize that both blob positions are valid and recognize the article as genuine, even if provided from different production cycles.
  • the method of the invention may comprise the following imaging steps:
  • Image processing comprising feature extraction techniques are well known in the field of 2D and 3D image processing and are not further described here. It is referred therefor to the following publications that are incorporated herein in their entirety:
  • Ultrasonic imaging techniques may also be used, as they allow to recognize the presence and shape of at least a portion of the layer 10 by sending a sound wave at a particular frequency and tuning that frequency in for the sound wave’s reflection.
  • Thermal imaging may be deployed also and are similar to optical techniques, with the difference that thermal effects are detected.
  • the heater in an aerosol-generating device may be used to generate the heat source to provide an infrared image.
  • the invention also provides an aerosol-generating system comprising an aerosol-generating device 2 and an aerosol-generating consumable article 1 , also defined as consumable, that is inserted, at least partially, in said aerosol-generating device 2.
  • the consumable article 1 comprises at least one layer 10 as described herein.
